Abstract Repeatedly frying process of dietary edible oil has a potential role in the generation of free radicals. Therefore, questions have always been raised as to whether, there is an efficient and economical method to reduce the harmful effects of repeated use of frying edible oil. Since hibiscus has been stated to have a wide variety of therapeutic effects, it was important to investigate its properties against harmful effects of free radicals. The current study aspires to find out whether irradiated powder of hibiscus has a protective role against adverse effects of repeated use of frying edible oil. Thirty-five adult male albino rats were equally assigned into five groups. First group"G1" was fed with normal diet as control group, meanwhile, group"G2" the diet mixed with fresh oil, "G3" diet mixed with repeatedly frying oil only, "G4" diet mixed with frying oil treated with hibiscus and "G5" diet mixed with frying oil treated with irradiated hibiscus. Feeding duration was six weeks. Fatty acid analyses of oil as well as peroxide values were determined. Blood and liver samples were collected for biochemical analyses as well as histological study. Repeatedly heated cooked oil has significant increases in peroxide value, acid value, free fatty acid and both conjugated diene and triene compared with repeatedly frying oil treated with hibiscus. Also there are significant increases in cholesterol and triglyceride and impaired in liver functions in "G3"compared with others. In addition, relative to the hibiscus groups, there is a substantial reduction in oxygen consumption in "G3". Both hibiscus as well as irradiated hibiscus attract attention in order to play a vital and economical role against harmful effects of frequent use of frying edible oil on some biological functions but, irradiated hibiscus was more effective.

Resumo O processo de fritura repetida de óleo comestível da dieta tem papel potencial na geração de radicais livres que podem ter efeitos prejudiciais em algumas funções biológicas. Portanto, sempre se questionou se existe uma maneira eficiente e econômica de prevenir ou pelo menos reduzir os efeitos nocivos do uso repetido de óleo comestível para fritar. Como o hibisco tem ampla variedade de efeitos terapêuticos, foi importante investigar suas propriedades como agente antioxidante contra os efeitos nocivos dos radicais livres. O presente estudo pretende descobrir se o pó irradiado de hibisco tem papel protetor contra os efeitos adversos do uso repetido de óleo comestível para fritar. Trinta e cinco ratos albinos machos adultos foram divididos igualmente em cinco grupos. O primeiro grupo "G1" foi alimentado com dieta normal como grupo controle, enquanto o grupo "G2" dieta misturada com óleo fresco, dieta "G3" misturada com óleo de fritura repetida, dieta "G4" misturada com óleo de fritura tratada com hibisco e dieta "G5" misturada com óleo de fritura tratada com hibisco irradiado. A duração da alimentação foi de seis semanas. Foram determinadas as análises de ácidos graxos de óleo, bem como os valores de peróxidos. Amostras de sangue e fígado foram coletadas para análises bioquímicas e estudo histológico. O óleo cozido repetidamente aquecido tem aumentos significativos no valor de peróxido, valor de ácido, ácido graxo livre e dieno e trieno conjugados em comparação com óleo de fritura repetidamente tratado com hibisco. Também há aumentos significativos no colesterol e triglicérides e comprometimento das funções hepáticas no "G3" em comparação com outros. Além disso, em relação aos grupos de hibiscos, há uma redução substancial no consumo de oxigênio no "G3". Tanto o hibisco como o hibisco irradiado chamam atenção por desempenhar papel vital e econômico contra os efeitos nocivos do uso frequente de óleo comestível para fritar em algumas funções biológicas, mas o hibisco irradiado foi mais eficaz.

La diabetes mellitus tipo 2 (DM2) es un factor de riesgo cardiovascular (FRCV) mayor. La DM confiere dos a cuatro veces más riesgo cardiovascular (RCV). El riesgo es aún más elevado en el paciente con DM2 que ha sufrido un infarto agudo de miocardio (IAM) o un accidente cerebrovascular (ACV). La dislipidemia de la DM2 consiste en triglicéridos elevados de ayuno, con mayor excursión posprandial, bajos niveles de HDLc, y alteraciones cuantitativas y cualitativas de LDLc y HDLc. El control glucémico apropiado en DM2 mejora en gran medida las alteraciones lipoproteicas. La terapia hipolipemiante es clave para reducir el RCV en la DM2. La reducción del RCV que se consigue con estatinas se basa en la reducción del LDLc y sus efectos pleiotrópicos. En pacientes que persisten con el perfil lipídico alterado, a pesar de dosis altas de estatinas, se debe considerar el agregado de otros agentes hipolipemiantes para reducir las lipoproteínas aterogénicas.

Type 2 diabetes (T2D) is a major cardiovascular risk factor (CVRF). Diabetes confers two to four times more cardiovascular risk (CVR). The risk is even higher in patients with T2D who have suffered an acute myocardial infarction (AMI) or cerebrovascular accident (CVA). The dyslipidemia of T2D consists of high fasting triglycerides, with greater postprandial excursion, low levels of HDLc and qualitative alterations of LDLc and HDLc. Appropriate glycemic control in T2D greatly improves lipoprotein abnormalities. Lipid-lowering therapy is key to reducing CVR in T2D. The CVR reduction achieved with statins is based on the reduction of LDLc. In patients who persist with an altered lipid profile despite highdose statins, the addition of other lipid-lowering agents to reduce atherogenic lipoproteins may be considered.

Excess weight causes disorders in locomotor, cardiorespiratory and reproductive systems and increases the incidence of endocrinopathies, as well it can often cause dyslipidemias, leading to atherosclerosis. Aims: Report the evolution of homeopathic treatment in 4 overweight patients, being 2 female dogs and 2 female rabbits with hypertriglyceridemia, analyzing the values in biochemical test. Methodology:Homeopathic treatment was chosen, based on the principle of similitude, using Cholesterinum due to its action to decrease cholesterol and triglyceride levels. Results:The same protocol was made for all of the four patients, included 2 globules of Cholesterinum 30CH direct in its mouth, every 12 hours for 30 days. The first dog attended on 01/09/2019, and presented 328 mg/dL of triglycerides, decreasing this level to 132 mg/dL after just one-monthtreatment. The second dog attended on 04/05/2019, presented higher hypertriglyceridemia with 617 mg/dL that decreased to 259 mg/dL. Likewise, on 02/06/2019, the first rabbit attended, presented 445mg/dL of triglycerides, which were reduced to 337 mg/dL, while the second rabbit, on 06/27/2019, presented 372 mg/dL of triglycerides, decreasing to 274 mg/dL after. Although the values of cholesterol in all patients were in agreement with the reference, the treatment still proved improvements. In the beginning of the treatment, the first dog showed 207 mg/dL of cholesterol and in the end, it reduced to 170 mg/dL, as well with the second dog with 218 mg/dL in the beginning and 200 mg/dL after. Regarding rabbits, the first one presented an initialvalue of 60 mg/dL, which decreased to 52 mg/dL, while the second started with 57 mg/dL and went to 41 mg/dL. Conventionally, Bezafibrate is indicated as a lipid-lowering agent, but it is contraindicated in patients with liver or kidney failure, vesicular diseases,and for pregnant or lactating. Conclusion:Dyslipidemia can be controlled with High dilution. (The exposed information is consented by the tutors)

Introduction Intracranial aneurysm (IA) is a major healthcare concern. The use of statin to reduce serum cholesterol has shown evidence to reduce cardiovascular risk in various diseases, but the impact on IA has not been described. This study aims to determine whether statin use, and serum cholesterol levels interfere with outcomes after IA event. Methods A cohort of patients with IA was analyzed. Patients social and demographics data were collected.Modified Rankin scale (mRS) score after 6months of follow-up was the endpoint. The data regarding statins use, presence or not of atherosclerotic plaque in radiological images and serum cholesterol of 35 patients were included in our study. Linear regression models were used to determine the influence of those 6 variables in the clinical outcome. Results The prevalence of atherosclerotic plaque, high cholesterol and use of statins was 34.3%, 48.5%, and 14.2%, respectively. Statins and serum cholesterol did not impact the overall outcome,measured by mRS after 6 months (p>0.05), but did show different tendencies when separated by IA rupture status. Serum cholesterol shows na important association with rupture of aneurysm (p»0.0382). High cholesterol and use of statins show a tendency for worse outcome with ruptured aneurysm, and the opposite is true for unruptured aneurysm. The presence of atherosclerotic plaques was not related with worse outcomes. Conclusions Multiple and opposite mechanisms might be involved in the pathophysiology of IA. Ruptured aneurysms are associated with higher levels of serum cholesterol. Serum cholesterol and statins use were not correlated with worse outcomes, but further studies are important to clarify these relationships.

Introdução Aneurisma intracranial (AI) é uma grande preocupação para a saúde. Evidências apontam que o uso de estatina para reduzir o colesterol sérico diminui o risco cardiovascular em diversas doenças, mas o impacto em AI ainda não foi descrito. Este estudo almeja determinar se o uso de estatina e o nível sérico de colesterol interferem no desfecho clínico após a ocorrência de AIs. Métodos Uma coorte de pacientes com AI foi analisada. Os dados sociodemográficos dos pacientes foram coletados. Ao final de 6 meses de acompanhamento, aplicou-se a escala modificada de Rankin (mRS). Os dados sobre uso de estatina, existência de placa aterosclerótica em imagens radiológicas, e colesterol sérico de 35 pacientes foram incluídos no estudo. Modelos de regressão linear foram usados para determinar a influência dessas 6 variáveis nos desfechos clínicos. Resultados A prevalência de placa aterosclerótica, colesterol elevado, e uso de estatina foram respectivamente 34,3%, 48,5% e 14,2%. Estatina e colesterol sérico não impactaram nos desfechos medidos pela mRS em 6 meses (p > 0,05), mas mostraram diferentes tendências quando separados pelo estado de ruptura do AI. Colesterol sérico apresenta uma importante associação com ruptura de aneurisma (p » 0,0382). Colesterol elevado e uso de estatinas representam uma tendência a piores desfechos para aneurismas rompidos, e o oposto é verdade para os não rompidos. A presença de placa aterosclerótica não está relacionada com piores resultados. Conclusões Mecanismos múltiplos e opostos podem estar envolvidos na patofisio logia do AI. Aneurismas rompidos estão associados com maiores níveis de colesterol sérico. Colesterol sérico e estatinas não foram correlacionados com piores desfechos, mas mais estudos são importantes para clarificar a relação entre esses fatores

The aim of the study was to evaluate the effect of the volume of participation in exercise programs offered in Primary Health Care (PHC), for 24 weeks on blood biochemical parameters of adult women. Three Basic Health Units in Rio Claro City (São Paulo) were selected and 2 exercise inter-ventions were implemented with different volumes (3 weekly sessions, 90 minutes each; 2 weekly sessions, 60 minutes each). In total, 53 participants remained until the end of the interventions. Regardless of their number of absences, they were divided into 4 groups, according to the volume of participation (calculated individually according to the duration of sessions and the number of classes held), forming groups according to quartiles: Low Volume Group (LVG; 57.62 ± 9.97 years-old), Low Medium Volume Group (LMVG; 56.31 ± 12.18 years-old), High Medium Volume Group (HMVG; 53.00 ± 10.25 years-old), and High-Volume Group (HVG; 59.69 ± 7.66 years-old). Blood biochemical parameters were dosed using the ELISA method. The Generalized Estimation Equa-tion Model was used to compare the biochemical parameters (time, group, and interaction; p ≤ 0.05). The analysis showed significant and positive time effect for low-density lipoproteins (LDL) and glycemia in all groups and for total cholesterol (TC) in LVG, LMVG and HMVG; a significant group effect for HVG on TC (higher levels compared to all other groups) and LDL (higher levels compared to LVG and LMVG). It is concluded that the physical exercise programs offered in the PHC contributed to a significant reduction in LDL and blood glucose levels, regardless of the vol-ume of participation of individuals in the programs

O objetivo do presente estudo foi avaliar o efeito do volume de participação em programas de exercícios, ofer-tados na Atenção Primária à Saúde (APS), durante 24 semanas, nos parâmetros bioquímicos sanguíneos de mulheres adultas. Foram selecionadas 03 Unidades Básicas de Saúde de Rio Claro-São Paulo e implementa-das 2 intervenções de exercícios com diferentes volumes (3 sessões/semana, 90 minutos cada; 2 sessões/semana, 60 minutos cada). No total, 53 participantes se mantiveram até o final das intervenções, independentemente do número de faltas foram divididos em 4 grupos, de acordo com o volume de participação (calculado con-forme a duração das sessões e a quantidade de aulas realizadas de forma individual), formando os grupos segundo os quartis: Grupo Baixo Volume (GBV; 57,62 ± 9,97 anos), Grupo Baixo Médio Volume (GBMV; 56,31 ± 12,18 anos), Grupo Médio Alto Volume (GMAV; 53,00 ± 10,25 anos) e Grupo Alto Volume (GAV; 59,69 ± 7,66 anos). Os parâmetros bioquímicos sanguíneos foram dosados pelo método ELISA. Foi utilizado o Modelo de Equações de Estimações Generalizadas para a comparação dos parâmetros bioquímicos (tempo, grupo e interação; p ≤ 0,05). A análise evidenciou efeito significativo favorável do tempo para lipoproteínas de baixa densidade (LDL) e glicemia em todos os grupos e para colesterol total (CT) no GVB, GBMV e GMAV; e efeito significativo do grupo para GAV no CT (maiores níveis comparado a todos os grupos) e LDL (maiores níveis comparados ao GBV e GBMV ). Conclui-se que o programa de exercício físico ofertado na APS contribuiu para a redução significativa dos níveis de LDL e glicemia, independentemente do volume de participação dos indivíduos nos programas

Cardiovascular disease(CVD) remains the major cause of mortality in the world, typically claiming a third of all deaths. The primary cause of CVD is atherosclerosis. Therefore, timely prevention and therapy of atherosclerosis are able to reduce the risk of the development of its clinical manifestations. Anti-atherosclerotic activity of medicinal plants mainly appears in their multiple effects.This study was carried out to evaluate the hypolipidemic activity of virgin olive oil in experimentally induced hyperlipemic Wistar. A total of 24 rats were randomly allocated to 4 equal groups and treated as follows for 50 days: (1) Normal control (NC); that were fed with a standart diet; (2) High Cholesterol Diet Control (HCD); which received high cholesterol diet for 50 days; (3) Animals receiving high cholesterol diet for 50 days, after this period the animals are fed for eight days by the standard foodand receiving by gavage virgin olive oil (HCD+VOO) and(4) Animals fed for eight days with the standard food and receiving by gavage olive oil (VOO). High Cholesterol Diet containing yolk egg and coconut oil. Results showed that olive oil caused a significant (p < 0.01) reduction in serum levels of Total Cholesterol (TC), Triglycerides (TG), Low­Density Lipoprotein Cholesterol (LDL) and Atherogenic Index Serum (AIS). The results also demonstrated a significant (p < 0.01) increase in High­Density Lipoprotein Cholesterol (HDL). Moreover, virgin olive oil induced a significant reduction in liver lipid content. On the other hand, a High cholesterol diet induced oxidative stress was measured by estimating reduced glutathione level and amount of thiobarbituric acid reactive substances (TBARS) formed as an index of lipid peroxidation in a liver and a heart. Virgin olive oil supplementation attenuated all these variations. Our observations of the study indicate that the virgin olive oil has a significant antihyperlipidemic potential.

OBJECTIVE@#To investigate the abnormality and distribution of plasma cholesterol levels in single-center hospitalized children.@*METHODS@#The blood lipid levels of children aged 2-18 years who had blood lipid test results in Peking University First Hospital from June 2016 to June 2019 were etrospectively analyzed. Cholesterol oxidase method was used for total cholesterol, and high-density lipoprotein cholesterol and low-density lipoprotein cholesterol were detected by clearance method. The counting data were compared with chi-square test.@*RESULTS@#The survey had involved 11 829 children (7 087 were boys and 4 742 were girls). 1 822 (15.4%) children were with elevated total cholesterol, 1 371 (11.6%) children with elevated low-density lipoprotein cholesterol, and 2 798 (23.7%) children with high-density lipoprotein cholesterol reduction. The total number of the children with abnormal cholesterol levels was 4 427 (37.4%). Among the 7 835 children who visited hospital due to the disease not commonly inducing dyslipidemia, 731 (9.3%) had elevated TC, 561 (7.2%) had elevated LDL-C, 1 886 (24.1%) had decreased HDL-C, and 2 576 (32.9%) had abnormal cholesterol levels. Among the children with different diseases, the difference in the incidence of abnormal cholesterol was statistically significant. The top three main groups of the children with increased total cholesterol and low-density lipoprotein cholesterol were "dyslipidemia", "urinary tract disease", and "nutritional disease"; The top three main groups of the children with reduced high-density lipoprotein cholesterol were "respiratory diseases", "dyslipidemia", "hematological diseases and malignant tumors". Among the 1 257 blood li-pid test results sent by other departments, 300 cases had abnormal cholesterol levels (23.8%). Among them, there were 70 children with hypercholesterolemia (5.6%), 44 children with increased low-density lipoprotein cholesterol (3.5%), and 224 children with reduced high-density lipoprotein cholesterol (17.8%). There were 365 (4.6%) children with low-density lipoprotein cholesterol ≥140 mg/dL (3.6 mmol/L) who needed to further exclude familiar hypercholesterolemia among the children who visited hospitals due to the disease not commonly inducing dyslipidemia.@*CONCLUSION@#Children in hospitals have a high incidence of cholesterol abnormalities. Doctors need to pay more attention to the cholesterol diagnosis and management regardless of the discipline, which not only helps to control secondary hypercholesterolemia, but also provides the possibility of detecting familial hypercholesterolemia in time.

Objective: To compare clinical efficacy between laparoscopic radical proximal gastrectomy with double-tract reconstruction (LPG-DTR) and laparoscopic radical total gastrectomy with Roux-en-Y reconstruction (LTG-RY) in patients with early upper gastric cancer, and to provide a reference for the selection of surgical methods in early upper gastric cancer. Methods: A retrospective cohort study method was carried out. Clinical data of 80 patients with early upper gastric cancer who underwent LPG-DTR or LTG-RY by the same surgical team at the Department of General Surgery, the First Affiliated Hospital of Xi'an Jiaotong University from January 2018 to January 2021 were retrospectively analyzed. Patients were divided into the DTR group (32 cases) and R-Y group (48 cases) according to surgical procedures and digestive tract reconstruction methods. Surgical and pathological characteristics, postoperative complications (short-term complications within 30 days after surgery and long-term complications after postoperative 30 days), survival time and nutritinal status were compared between the two groups. For nutritional status, reduction rate was used to represent the changes in total protein, albumin, total cholesterol, body mass, hemoglobin and vitamin B12 levels at postoperative 1-year and 2-year. Non-normally distributed continuous data were presented as median (interquartile range), and the Mann-Whitney U test was used for comparison between groups. The χ(2) test or Fisher's exact test was used for comparison of data between groups. The Mann-Whitney U test was used to compare the ranked data between groups. The survival rate was calculated by Kaplan-Meier method categorical, and compared by using the log-rank test. Results: There were no statistically significant differences in baseline data betweeen the two groups, except that patients in the R-Y group were oldere and had larger tumor. Patients of both groups successfully completed the operation without conversion to laparotomy, combined organ resection, or perioperative death. There were no significant differences in the distance from proximal resection margin to superior margin of tumor, postoperative hospital stay, time to flatus and food-taking, hospitalization cost, short- and long-term complications between the two groups (all P>0.05). Compared with the R-Y group, the DTR group had shorter distal margins [(3.2±0.5) cm vs. (11.7±2.0) cm, t=-23.033, P<0.001], longer surgery time [232.5 (63.7) minutes vs. 185.0 (63.0) minutes, Z=-3.238, P=0.001], longer anastomosis time [62.5 (17.5) minutes vs. 40.0 (10.0) minutes, Z=-6.321, P<0.001], less intraoperative blood loss [(138.1±51.6) ml vs. (184.3±62.1) ml, t=-3.477, P=0.001], with significant differences (all P<0.05). The median follow-up of the whole group was 18 months, and the 2-year cancer-specific survival rate was 97.5%, with 100% in the DTR group and 95.8% in the R-Y group (P=0.373). Compared with R-Y group at postoperative 1 year, the reduction rate of weight, hemoglobin and vitamin B12 were lower in DTR group with significant differences (all P<0.05); at postoperative 2-year, the reduction rate of vitamin B12 was still lower with significant differences (P<0.001), but the reduction rates of total protein, albumin, total cholesterol, body weight and hemoglobin were similar between the two groups (all P>0.05). Conclusions: LPG-DTR is safe and feasible in the treatment of early upper gastric cancer. The short-term postoperative nutritional status and long-term vitamin B12 levels of patients undergoing LPG-DTR are superior to those undergoing LTG-RY.

OBJECTIVE@#To analyze the effect of Xuezhikang on the markers of the serum lipid levels of cholesterol synthesis and absorption in early menopausal women with hypercholesterolemia, and preliminarily explore its lipid-lowering mechanism.@*METHODS@#A total of 90 early menopausal women with hypercholesterolemia were enrolled from December, 2014 to May, 2016 from Beijing Anzhen Hospital, Capital Medical University, who were randomly allocated to receive Xuezhikang (1200 mg/d, orally) or atorvastatin (10 mg/d, orally) according to a random number table. Serum levels of some related biomarkers, including cholesterol synthesis markers (squalene, dihydrocholesterol, dehydrocholesterol, and lathosterol), and absorption markers (campesterol, stigmasterol, and sitosterol) as well as safety indices were obtained at baseline and after 8 weeks of the intervention.@*RESULTS@#Eight weeks after treatment, both Xuezhikang and atorvastatin significantly reduced the levels of total cholesterol, triglycerides, low density cholesterol compared to baseline (all P<0.01). Xuezhikang significantly reduced the levels of squalene, dehydrocholesterol and lathosterol compared to baseline (all P<0.01), but atorvastatin only significantly reduced the level of squalene (P<0.01), compared to baseline. All cholesterol absorption markers showed no significant differences before and after treatment (P>0.05), however, a more obvious downward trend was shown in the Xuezhikang group. In addition, all the safety indices showed no significant differences between the two groups. Although the creatinekinase level in the Xuezhikang group was significantly higher, it remained within the safe range.@*CONCLUSIONS@#Xuezhikang may have more comprehensive effects on the markers of cholesterol synthesis and metabolism in early menopausal women with hypercholesterolemia through ergosterol and flavonoids in its "natural polypill."

OBJECTIVE@#This study aimed to investigate the effects of caprylic acid (C8:0) on lipid metabolism and inflammation, and examine the mechanisms underlying these effects in mice and cells.@*METHODS@#Fifty-six 6-week-old male C57BL/6J mice were randomly allocated to four groups fed a high-fat diet (HFD) without or with 2% C8:0, palmitic acid (C16:0) or eicosapentaenoic acid (EPA). RAW246.7 cells were randomly divided into five groups: normal, lipopolysaccharide (LPS), LPS+C8:0, LPS+EPA and LPS+cAMP. The serum lipid profiles, inflammatory biomolecules, and ABCA1 and JAK2/STAT3 mRNA and protein expression were measured.@*RESULTS@#C8:0 decreased TC and LDL-C, and increased the HDL-C/LDL-C ratio after injection of LPS. Without LPS, it decreased TC in mice ( P < 0.05). Moreover, C8:0 decreased the inflammatory response after LPS treatment in both mice and cells ( P < 0.05). Mechanistic investigations in C57BL/6J mouse aortas after injection of LPS indicated that C8:0 resulted in higher ABCA1 and JAK2/STAT3 expression than that with HFD, C16:0 and EPA, and resulted in lower TNF-α, NF-κB mRNA expression than that with HFD ( P < 0.05). In RAW 264.7 cells, C8:0 resulted in lower expression of pNF-κBP65 than that in the LPS group, and higher protein expression of ABCA1, p-JAK2 and p-STAT3 than that in the LPS and LPS+cAMP groups ( P < 0.05).@*CONCLUSION@#Our studies demonstrated that C8:0 may play an important role in lipid metabolism and the inflammatory response, and the mechanism may be associated with ABCA1 and the p-JAK2/p-STAT3 signaling pathway.

Mounting evidence has shown that exercise exerts extensive beneficial effects, including preventing and protecting against chronic diseases, through improving metabolism and other mechanisms. Recent studies have shown that exercise preconditioning affords significant cardioprotective effects. However, whether exercise preconditioning improves high fat diet (HFD)-induced obesity and lipid metabolic disorder remains unknown. The study was aimed to explore the effects of exercise preconditioning on HFD-induced obesity and lipid metabolic disorder in mice. 4-week-old C57BL/6 mice were subjected to swimming or sedentary control for 3 months, and then were fed with normal diet (ND) or HFD for 4 more months. The results showed that the blood glucose was decreased, and the glucose tolerance and grip strength were increased in exercised mice after training. Exercise preconditioning failed to improve HFD-induced body weight gain, but improved HFD-induced glucose intolerance. Exercise preconditioning showed no significant effects on both exercise capacity and physical activity in ND- and HFD-fed mice. HFD feeding increased total cholesterol and low density lipoprotein (LDL) levels in circulation, promoted subcutaneous fat and epididymal fat accumulation in mice. Exercise preconditioning increased circulating high density lipoprotein (HDL) and decreased circulating LDL, without affecting the subcutaneous fat and epididymal fat in HFD-fed mice. HFD feeding increased liver weight and hepatic total cholesterol contents, and dysregulated the expressions of several mitochondria function-related proteins in mice. These abnormalities were partially reversed by exercise preconditioning. Together, these results suggest that exercise preconditioning can partially reverse the HFD-induced lipid metabolic disorder and hepatic dysfunction, and these beneficial effects of exercise sustain for a period of time, even after exercise is discontinued.

O câncer colorretal (CCR) é o terceiro câncer mais diagnosticado em humanos. O CCR causou mais de 900.000 mortes em 2020 e foi estimado, para o período entre 2020 - 2025, um incremento de 13.5 % no número de casos novos de acordo com a plataforma Web Global Cancer Observatory. A Terapia Fotodinâmica (PDT) é uma alternativa terapêutica promissora. Conhecer as vias de sinalização de morte celular, assim como, as respostas associadas com a resistência ao dano foto-oxidativo, são relevantes para incrementar a eficiência da PDT. Neste trabalho, investigamos como as células de adenocarcinoma colorretal HT 29 respondem ao dano fotoinduzido gerado pelo fotossensibilizador (FS) meso-tetrafenilporfirina dissulfônado (TPPS2a), uma molécula que é ativada pela irradiação com luz em 522 nm. Como esperado, após irradiação (2.1 J cm-2) foi verificado que com o incremento do TPPS2a houve diminuição da viabilidade celular. A concentração do FS escolhida para darmos seguimento ao estudo foi a necessária para reduzir em 30 % a sobrevida celular (DL30; 148 nM). Abordagens moleculares nos permitiram identificar que nas células fotossensibilizadas a redução na maturação da catepsina D (CTSD, 55 %) e da catepsina B (CTSB, 52 %) contribuem com a disfunção endolisossomal. Além disso, comprovamos que as células fotossensibilizadas tiveram, pela menor quantidade de CTSD ativa, o processamento da prosaposina (PSAP) significativamente afetado. Células coletadas após 24 horas de irradiação expressaram 7 vezes mais PSAP do que as amostras dos grupos controle, sugerindo que as reações de oxidação causadas pelo TPPS2a podem ocasionar o acúmulo de glicoesfingolipídios nos endossomos e nos lisossomos, mimetizando o fenótipo observado em doenças de armazenamento lisossomal. Imagens de células HT 29 com expressão estável da proteína LGALS3 fusionada ao marcador EFGP mostraram que, após 24 horas de irradiação, as células não ativaram a lisofagia para remover os endossomos e os lisossomos danificados. A ausência do recrutamento da LGALS3 também apontou que as membranas dos endossomos e dos lisossomos não apresentam rupturas permanentes que permitam a passagem de uma molécula de 26 kDa. Experimentos complementares de análise da expressão proteica dos marcadores autofágicos LC3-II e p62/SQSTM1 (referida como p62) confirmaram o bloqueio do fluxo autofágico nas células fotosenssibilizadas. Pelo envolvimento do sistema endolisossomal no tráfego de membranas e no fluxo de lipídios, o aumento da transcrição da Hidroximetilglutaril-CoA reductase (HMGCR) (≈ 1.6 vezes) uma enzima envolvida na síntese de novo do colesterol - sugeriu que a disfunção dos endossomos e dos lisossomos altera a distribuição de colesterol. Não obstante, para manter a homeostase lipídica nas células fotossensibilizadas este não foi o único mecanismocompensatório acionado, uma vez que houve um incremento sutil; porém, significativo (1.2 vezes) na transcrição da ceramidase ácida (ASAH1). Em conjunto, nossos dados apontam que a fotossensibilização com TPPS2a constitui uma ferramenta promissora para causar dano no sistema endolisossomal, inibindo a autofagia e permitindo o estudo das respostas metabólicas em células expostas a estresse oxidativo

Colorectal cancer (CRC) is the third most commonly diagnosed cancer in humans. CRC caused more than 900,000 deaths in 2020 and it was estimated for the period 2020 - 2025, an increase of 13.5 % in the number of new cases according to the Global Cancer Observatory Web platform. Photodynamic Therapy (PDT) is a promising therapeutic alternative. Understandings of cell death signaling pathways as well as the adaptive responses associated with resistance to photo-oxidative damage are relevant to optimize the effectiveness of PDT. For this purpose, in this research, we investigated how HT-29 colorectal adenocarcinoma cells respond to photosensitization reactions generated by TPPS2a, a molecule activated by irradiation with light at 522 nm. PS concentrations displayed increased inhibitory effect on cell viability after irradiation (2.1 J cm-2). The lethal dose selected to photosensibilize cells was the TPPS2a concentration able to reduce 30 % of cell survival (LD30; 148 nM). By molecular methods, we observed a reduction in cathepsin D (CTSD, 55 %) and cathepsin B (CTSB, 52 %) maturation, depletion that may contribute to endo-lysosomal dysfunction in photosensitized cells. It is widely known that endo-lysosomal cathepsins are crucial in protein turnover and degradation. Thus, we focused on the consequence of CTSD reduction. Literature data indicate that CTSD plays a key role in prosaposin (PSAP) processing to the four saposins (SAPs) that are required in glycosphingolipids breakdown. In fact, our results in photosensitized cells showed that, due to the lower amount of active CTSD, PSAP processing was significantly affected. Cells collected after irradiation expressed 7 times more PSAP than cells from the control groups. This data suggest that oxidative photodamage induced by TPPS2a may result in glycosphingolipid-accumulating endosomes and lysosomes, phenotype which mimics lysosomal storage diseases. Furthermore, we monitored by fluorescence microscopy a form of selective autophagy which detects and removes damaged endosomes and lysosomes known as lysophagy. Images of HT-29 cells expressing Galectin 3/LGALS3 fused to EFGP showed that photosensitized cells did not activate lysophagy. The absence of LGALS3 recruitment also indicated that the membranes of endosomes and lysosomes do not present ruptures which allow the passage of proteins with a molecular weight up to at least 26 kDa. Protein expression analysis of the autophagic markers LC3-II and p62/SQSTM1 (referred as p62) confirmed autophagic flux blockade in cells challenged with photoactivated TPPS2a. The endo-lysosomal system plays a key role in membrane trafficking and lipid flux. At the transcriptional level, 1.6-fold increase in gene expression of Hydroxymethylglutaryl-CoA reductase (HMGCR) - an enzyme involved in the synthesis de novo of cholesterol - indicated that endosomes and lysosomes dysfunction alters the distribution of cholesterol in cellschallenged with photoactivated TPPS2a. However, to maintain lipid homeostasis in photosensitized cells, this was not the only compensatory mechanism triggered, since there was a slightly increase (1.2-fold) in the transcription of acid ceramidase (ASAH1). Taken together, our data showed that photosensitization with TPPS2a constitutes a promising tool to damage the endolysosomal system, to inhibit autophagy and to study metabolic responses in cells exposed to oxidative stress

ABSTRACT The present study estimate the prevalence of negative self-rated health and to analyze its association with simultaneous risk behaviors (insufficient levels of physical activity, greater exposure to sedentary time and inappropriate sleep time) in students at a public university in the state from Minas Gerais, Brazil. It consists of cross-sectional study, with data collected through a questionnaire. The outcome variable was negative self-rated health. The independent variables were estimated by the questions related to the time spent on physical activity, sitting and sleep time, and these three behaviors were considered according to the risk criteria (none, one, two and three risk behaviors). The association was estimated by the Prevalence Ratios (PR), via Poisson regression. 1,110 students participated in the study. The prevalence of negative self-rated health among university students was 47.3%, and the prevalence of two risk behaviors and three risk behaviors were 41.3% and 11.3%, respectively. The simultaneous occurrence of three risk behaviors was associated with negative self-rated health in university students. The information in this study makes it possible to characterize the need for actions to promote health in the university environment.

Abstract Hepatoprotective effects of many herbal agents have been reported in animal studies and clinical trials. In this study, five hepatoprotective plants with potent antioxidant, anti-inflammatory, and hypolipidemic effects were chosen to prepare a polyherbal compound for managing NAFLD. Sixty patients with NAFLD were randomly divided into treatment and control groups (2:1 ratio). Both group were advised to take healthy diet and exercise. The treatment group also received herbal capsules containing 400 mg of the mixture of Anethum graveolens, Citrus aurantium, Cynara scolymus, Portulaca oleracea, and Silybum marianum (2 capsules, thrice daily, for two months). The liver ultrasound and biochemical markers including the serum lipids, liver enzymes, and glucose were evaluated before starting the study and at the end of the treatment. Thirty patients in the treatment group and sixteen patients in the control group completed the study. The herbal compound significantly decreased the serum level of alanine transaminase (ALT), aspartate transaminase (AST), and total cholesterol. Treatment with the herbal compound significantly improved the grade of the fatty liver, but no significant change was found in the control group. In conclusion, the formulated herbal compound appeared to be effective in biochemical improvement and decreasing the grade of the fatty liver in the patients with NAFLD.

The use of plants in disease treatment is cost effective and relatively safe. This study was designed to investigate anti-hyperlipidemic and anti-diabetic activity of ethanolic leaf extract of Catharanthus roseus alone and in combination therapy in hyperlipidemic & diabetic mice. Eight groups comprising five mice each were used. Group A was hyperlipidemic control, group B, C, D received atorvastatin (20 mg/kg), leaf extract (200 mg/kg) and leaf extract in combination with atorvastatin (200 mg/kg and 20 mg/kg) orally for 15 days. Group E was diabetic control. Group F, G, H received sitagliptin (40 mg/kg), leaf extract (200 mg/kg) and extract in combination with sitagliptin (200 mg/kg and 40 mg/kg) orally for 7 days. Blood cholesterol levels were measured at 1st, 5th, 10th and 15th day and fasting blood sugar levels were measured at 2, 12, 24, 72 and 168 hours during treatment. One-way ANOVA with tukey- kramer multiple comparison test was used. The chemical characterization of ethanolic extract of Catharanthus roseus leaves showed presence of alkaloids, saponins, tannins and flavonoids. Ethanolic extract of Catharanthus roseus has significant anti-hyperlipidemic & anti-diabetic effects (p<0.05, p<0.01) when compared with control but had not cause significantly increase in anti-hyperlipidemic effects of atorvastatin. While significantly increased the antidiabetic effect of sitagliptin (p<0.05)

A series of N-(benzoylphenyl)-carboxamide derivatives (2a, 2b, 3a, 3b, 4a, 4b, 5a, 5b, 6a and 6b) was prepared with good yields by reacting the corresponding carbonyl chlorides with aminobenzophenones at room temperature. This was followed by evaluating the hypotriglyceridemic and hypocholesterolemic effects of 3b, 5a and 5b. Triton WR-1339 (300 mg/kg) was intraperitoneally administered to overnight-fasted rats to induce hyperlipidemia. Rats were divided into six groups: control, hyperlipidemic, hyperlipidemic plus compounds 3b, 5a and 5b and hyperlipidemic plus bezafibrate. Results showed that after 18 h of treatment at a dose of 15 mg/kg body weight of each of the test compounds, the elevated plasma levels of triglycerides (TG) and total cholesterol (TC) were significantly lowered by compounds 5b and 3b (p < 0.001) and by 5a (p < 0.0001), compared to the hyperlipidemic control group. Compounds 3b and 5a significantly increased levels of high-density lipoprotein cholesterol (HDL-C) by 58 and 71%, respectively. In addition, compounds 3b and 5a caused significant reduction (p < 0.0001) of low-density lipoprotein cholesterol (LDL-C) levels compared to the control group. These results suggest a promising potential for compounds 3b, 5a and 5b as lipid-lowering agents, which may contribute to reducing the risk of atherosclerosis and cardiovascular disease

: O exercício físico, em especial a corrida de rua tem sido recomendada para prevenção e tratamento de doenças crônicas não transmissíveis. O objetivo desta revisão sistemática foi verificar os efeitos de diferentes métodos de treinamento sobre os indicadores cardiometabólicos de corredores recreacionais. As bases de dados eletrônicas utilizadas na presente pesquisa foram: PUBMED, SCIENCE DIRECT, LILACS e COCHRANE LIBRARY, usando os descritores agrupados segundo o método PICO; População ("adults" OR "young adult" OR "middle aged") AND Intervenção ("endurance training" OR "aerobic training" OR "running") OR Comparação ("recreational runners" OR "jogging") AND Outcome/Desfecho ("cardiovascular risk factors" OR "cardiometabolic risk factors" OR "metabolic syndrome"). Na seleção os artigos foram excluídos por título, resumo e texto. Obteve-se um total de 813 artigos encontrados, no qual nove (9) preencheram os critérios de inclusão e baixo risco de viés de acordo com a Escala Testex. Foram encontrados três métodos de treinamento: Combinado (Contínuo +Intervalado); Contínuo e Intervalado. Considerando a somatória das amostras dos nove estudos, um total de 604 indivíduos (466 homens e 138 mulheres) participaram dos ensaios. Os diferentes métodos de treinamentos resultaram na redução dos níveis de triglicerídeos, insulina e glicose e na redução do colesterol total e LDL, e consequentemente o aumento do HDL. Na composição corporal houve diminuição significativa do peso e da gordura corporal, do IMC, na medida da circunferência da cintura, e no aumento da capacidade aeróbia (VO2). Concluiu-se que os treinamentos combinado, contínuo e intervalado podem ser aplicados para melhora dos indicadores cardiometabólicos, cada um dentro da sua especificidade de frequência, volume e intensidade.(AU)

Physical exercise, especially running, has been recommended for the prevention and treatment of chronic non-communicable diseases. The objective of this systematic review was to verify the effects of different training methods on the cardiometabolic indicators of recreational runners. The electronic databases used in the present research were: PUBMED, SCIENCE DIRECT, LILACS and COCHRANE LIBRARY, using the descriptors grouped according to the PICO method; Population ("adults" OR "young adult" OR "middle aged") AND Intervention ("endurance training" OR "aerobic training" OR "running") OR Comparison ("recreational runners" OR "jogging") AND Outcome / Outcome ("Cardiovascular risk factors" OR "cardiometabolic risk factors" OR "metabolic syndrome"). In the selection, articles were excluded by title, abstract and text. A total of 813 articles were obtained, in which nine (9) met the inclusion criteria and low risk of bias according to the Testex Scale. Three training methods were found: Combined (Continuous + Interval); Continuous and Interval. Considering the sum of the samples from the nine studies, a total of 604 individuals (466 men and 138 women) participated in the trials. The different training methods resulted in a reduction in the levels of triglycerides, insulin and glucose and in the reduction of total cholesterol and LDL, and consequently an increase in HDL. In body composition, there was a significant decrease in weight and body fat, in BMI, as measured by waist circumference, and in increased aerobic capacity (VO2). It is concluded that combined, continuous and interval training can be applied to improve cardiometabolic indicators, each within its specific frequency, volume and intensity.(AU)

The restriction of sodium intake, one of the pillars of antihypertensive treatment, has been associated with the increase in cholesterol levels. Given this, we hypothesize that a sodium intake restriction may increase cholesterol levels in hypertensive women. The present study aimed to evaluate the influence of sodium intake, sociodemo-graphic, lifestyle and anthropometric variables on the blood cholesterol levels of hypertensive women. This was a cross-sectional study with hypertensive and nondiabetic women aged 20 to 59 years, recruited from the primary healthcare units of Maceio, Alagoas, in the Brazilian Northeast. Sodium intake was estimated by the 24-hour urinary excretion of sodium; and blood cholesterol was estimated by capillary blood. Age (years), education level (<4 or ≥4 years), race (white or nonwhite), smoking and alcohol consumption were evaluated. The weight, height and waist circumference were measured and body mass index, conicity index and waist-to-height ratio were quantified. The percentage of body fat was measured using a tetrapolar bioelectrical impedance device. The relationship between blood cholesterol and other variables was assessed by multiple regression analysis. A significance level of 5% was used in the final model. This study included 165 hypertensive women. In linear regression, blood cholesterol was directly proportional to age (p<0.001), education level (p=0.01) and race (p=0.04). These variables, as well as sodium intake (p = 0.07) and conicity index (p = 0.12), were included in the multiple regression analysis. Sodium intake (p=0.03) and age (p=0.001) were related, in an inverse and a direct way, respectively, to the blood choles-terol in the hypertensive women studied. (AU)

ção da ingestão de sódio, um dos pilares do tratamento anti-hipertensivo, tem sido associada ao aumen-to dos níveis de colesterol. Diante disso, levantou-se a hipótese de que a ingestão de sódio influencia os níveis de colesterol de mulheres hipertensas, independentemente de outros fatores associados. Trata-se de um estudo transversal realizado com mulheres hipertensas e não diabéticas, na faixa etária entre 20 e 59 anos, recrutadas em unidades básicas de saúde de Maceió, Alagoas, situada no Nordeste do Brasil. A ingestão de sódio foi estimada pela excreção urinária de sódio de 24 horas; e o colesterol sérico foi mensurado por coleta de sangue capilar. Foram ava-liados idade (anos), escolaridade (<4 ou ≥4 anos), raça (branca ou não branca), tabagismo e consumo de álcool. O peso, a estatura e a circunferência da cintura foram aferidos e o índice de massa corporal, índice de conicidade e razão cintura/estatura foram calculados. A porcentagem de gordura corporal foi medida usando um dispositivo de impedância bioelétrica tetrapolar. A relação entre o colesterol sérico e as outras variáveis em estudo foi avalia-da por meio de análise de regressão múltipla, adotando-se um nível de significância de 5% no modelo final. Este estudo incluiu 165 mulheres hipertensas. Na análise de regressão linear, o colesterol sérico foi relacionado à idade (p<0,001), escolaridade (p=0,01) e raça (p=0,04). Essas variáveis, assim como o consumo de sódio (p=0,07) e o índice de conicidade (p=0,12), foram incluídas na análise de regressão múltipla. As variáveis que permaneceram no modelo final foram ingestão de sódio (p=0,03) e idade (p=0,001). A ingestão de sódio e a idade foram as variáveis que influenciaram o colesterol sérico de mulheres hipertensas. (AU)

Abstract Background: The use of androgenic anabolic steroids (AAS) is prevalent among young bodybuilders, motivated by aesthetic results. Although the medical community condemns this practice for its potential deleterious effect, we must recognize the need for more scientific research on the likelihood and magnitude of the adverse events. Objective: To evaluate whether high-quality, scientific evidence supports that AAS negatively affect lipid profile and promote muscle hypertrophy in resistance training practitioners. Methods: A systematic review of the literature of randomized clinical trials was conducted in the PubMed / Medline, Scielo and Science direct databases. The searches were conducted by two independent researchers by June 2018. A significance level of 5% was considered in the analysis. Results: Six clinical trials involving 170 resistance training practitioners were included. A significant heterogeneity was found in studies evaluating the effects of AAS on lipid profile and muscle hypertrophy (I² = 97, 95 and 91%, respectively), with no significant effects on HDL-cholesterol (-5.62mg/dL, 95%CI −12.10, 0.86, p= 0.09), LDL-cholesterol (7.76 mg/dL, 95%CI −9.70, 25.23, p= 0.57) and muscle hypertrophy (2.44kg 95%CI 0.02, 4.86, p=0.05). Conclusion: Current evidence does not support that low-to-moderate doses of AAS cause serious negative effects on lipid profile or promote muscle hypertrophy in resistance training practitioners.
