ABSTRACT

Abstract Galaxias maculatus aquaculture objectives is to produce millions of eggs. Wild females are small (2 g), have quick sexual maturity and low mean fecundity (500 eggs/female), requiring larger fishes with higher fecundity. This study aim is to evaluate experimentally the effect of the levels of protein, lipid and dietary energy on weight increases in adults. Five independent experiments were performed at different sequential time periods at the UCT hatchery, Chile. Specimens were obtained from a) Crystalline sea return specimen catches in the Tolten estuary (4 -6 cm, 0.3-0.4 g.). b) Hatchery cultured fish. Fish were fed by hand ad libitum. In experiments 1 to 4, pelleted diets were prepared with 3 to 5 levels of protein (treatments 27 up to 57%), crumble size, three 100 L fibre ponds replicates. In experiment 5 the effect of two lipid levels (8 and 21%) was evaluated with commercial extruded Salmon Nutra Starter isoproteic crumble 1 diet at 63%, replicated in 4 ponds. The results show: A tendency to increased weight in all sizes with an increased protein level in the pelleted diet.A maximal adult growth is obtained with a diet containing a minimum of 37% crude protein, with 40% the optimal value. A higher % protein in the diet or growth in weight lower feed conversion ratio. The feed conversion ratio in the extruded diet reaches up to 0.5 and in the pelleted vary from 0.7 to 1.5. Fish 0.6 g fed with 63% protein, extruded commercial diet with two different lipid levels (8 and 21%, 20.40 and 23.84 MJ kg-1, PE/TE 0.62 and 0.71) increased weight the first month 67 and 105% each. It has been established that high-energy diets with optimal levels of protein and lipid are a good short-term solution to obtain G. maculatus of higher weight.


Resumo O objetivo da aquicultura de Galaxias maculatus é produzir milhões de ovos. As fêmeas selvagens são pequenas (2 g) e têm maturidade sexual rápida e fecundidade média baixa (500 ovos/fêmea), necessitando de peixes maiores e com fecundidade superior. O objetivo deste estudo é avaliar experimentalmente o efeito dos níveis de proteínas, lipídios e energia da dieta sobre o aumento de peso em adultos. Cinco experimentos independentes foram realizados em diferentes períodos sequenciais de tempo no incubatório UCT, Chile. Os espécimes foram obtidos a partir de: a) capturas de espécimes de retorno do mar cristalino no estuário de Tolten (4-6 cm, 0,3-0,4 g); b) peixes de cultura em incubatório. Os peixes foram alimentados à mão ad libitum. Nos experimentos de 1 a 4, dietas peletizadas foram preparadas com três a cinco níveis de proteína (tratamentos 27 a 57%), tamanho do crumble, três repetições de tanques de fibra de 100 L. No experimento 5, o efeito de dois níveis de lipídios (8 e 21%) foi avaliado com dieta comercial isoproteica crumble 1 de Salmon Nutra Starter extrusada a 63%, replicada em quatro tanques. Os resultados mostram: uma tendência ao aumento de peso em todos os tamanhos, com um aumento do nível de proteína na dieta peletizada; um crescimento adulto máximo com uma dieta contendo um mínimo de 37% de proteína bruta, com 40% do valor ideal; uma porcentagem maior de proteína na dieta ou crescimento em peso com menor taxa de conversão alimentar. A taxa de conversão alimentar na dieta extrusada chega a 0,5, e na peletizada varia de 0,7 a 1,5. Peixes de 0,6 g alimentados com 63% de proteína e dieta comercial extrusada com dois níveis lipídicos diferentes (8 e 21%; 20,40 e 23,84 MJ kg-1; PE / TE 0,62 e 0,71) aumentaram de peso no primeiro mês em 67 e 105% cada, respectivamente. Foi estabelecido que dietas de alta energia com níveis ótimos de proteínas e lipídios são uma boa solução de curto prazo para obter G. maculatus de peso mais alto.

ABSTRACT

Abstract This study determines the associations among serum lipid profiles, risk of cardiovascular disease, and persistent organic pollutants. Using Gas chromatography technique, the intensity of toxic pollutant residues in serum samples of Hypertensive patients were measured. Based on statistical analysis, the effects of different covariates namely pesticides, age, systolic blood pressure, diastolic blood pressure, and lipid profile duration was checked using the logistic regression model. Statistical computation was performed on SPSS 22.0. The P-values of F-Statistic for each lipid profile class are greater than 0.01 (1%), therefore we cannot reject the null hypothesis for all cases. The estimated coefficients, their standard errors, Wald Statistic, and odds ratio of the binary logistic regression model for different lipid profile parameters indicate if pesticides increase then the logit value of different lipid profile parameters changes from -0.46 to -0.246 except LDL which increases by 0.135. The study reports a significantly increased threat of cardiovascular disease with increased concentrations of toxic pollutants.


Resumo Este estudo determina as associações entre o perfil lipídico sérico, o risco de doença cardiovascular e os poluentes orgânicos persistentes. Por meio da técnica de cromatografia gasosa, mediu-se a intensidade dos resíduos de poluentes tóxicos em amostras de soro de pacientes hipertensos. Com base na análise estatística, os efeitos de diferentes covariáveis ​​- ou seja, pesticidas, idade, pressão arterial sistólica, pressão arterial diastólica e duração do perfil lipídico - foram verificados usando o modelo de regressão logística. O cálculo estatístico foi realizado no SPSS 22.0. Os valores P da estatística F para cada classe de perfil lipídico são maiores que 0,01 (1%), portanto não podemos rejeitar a hipótese nula para todos os casos. Os coeficientes estimados, seus erros padrão, estatística de Wald e odds ratio do modelo de regressão logística binária para diferentes parâmetros do perfil lipídico indicam se os pesticidas aumentam, então o valor logit de diferentes parâmetros do perfil lipídico muda de -0,46 para -0,246, exceto LDL, que aumenta em 0,135. O estudo relata um aumento significativo da ameaça de doença cardiovascular com aumento das concentrações de poluentes tóxicos.

ABSTRACT

Introdução: estudos sugerem forte associação da exposição perinatal e pós-natal a dietas ricas em gordura e complicações cardiovasculares. Objetivo: avaliar os efeitos da exposição a dieta hiperlipídica no período perinatal e pós desmame sobre indicadores de risco cardiometabólico e alterações histomorfometrica na aorta em ratos. Metodologia: Ratas Wistar foram separadas em grupos de acordo com a dieta durante a gestação e lactação: dieta controle (n=3) e dieta hiperlipídica (n=3). No 21º dia de vida filhotes machos foram divididos em subgrupos (n=6): CC: formado por ratos expostos a dieta controle durante toda a vida; CH: formado por ratos cuja a mãe consumiu dieta controle e após o desmame os filhotes consumiram dieta hiperlipídica; HH: formado por filhotes expostos a dieta hiperlipídica durante toda a vida e HC: formado por ratos cuja a mãe consumiu dieta hiperlipídica e após o desmame os filhotes consumiram dieta controle. No 60º dia de vida, IMC, índices aterogênicos, proteína C reativa e histomorfometria da aorta dos descendentes foram avaliados. Resultados: o grupo HC apresentou maior IMC em comparação aos grupos HH e CH (p= 0,0004). A razão colesterol total / HDL-colesterol foi maior para o grupo CH comparado ao CC e HC (p = 0,016). Coeficiente aterogênico (p = 0,003), espessura da aorta (p = 0,003) e quantidade de lamelas elásticas (p = 0,0002) foram maiores nos grupos CH e HH em comparação a CC e HC. Conclusão: exposição a dieta hiperlipídica nos períodos perinatal e pós desmame aumentou o risco cardiometabólico e alterou a histomorfometria aórtica de ratos.


Background: studies suggest a strong association of perinatal and postnatal exposure to high-fat diets and cardiovascular complications. Objective: to evaluate the effects of exposure to a high-fat diet in the perinatal and post-weaning period on indicators of cardiometabolic risk and aorta histomorphometric changes in the rats. Methodology: Wistar rats were separated into groups according to the diet during pregnancy and lactation: control diet (n=3) and high fat diet (n=3). On the 21st day of life, male pups were divided into subgroups (n=6): CC: formed by rats exposed to a control diet for all life; CH: formed by rats whose mother consumed a control diet and after weaning the pups consumed a high-fat diet; HH: formed by pups exposed to a high-fat diet for all life and HC: formed by rats whose mother consumed a high-fat diet and after weaning the pups consumed a control diet. On the 60th day of life, BMI, atherogenic indices, C-reactive protein and histomorphometry of the aorta of the offspring were evaluated. Results: the HC group showed higher BMI compared to the HH and CH groups (p=0.0004). The total cholesterol / HDL-cholesterol ratio was higher for the CH group compared to CC and HC (p = 0.016). Atherogenic coefficient (p= 0,003), aortic thickness (p = 0.003) and amount of elastic lamellae (p = 0.0002) were higher in CH and HH groups compared to CC and HC. Conclusion: exposure to a high-fat diet in the perinatal and post-weaning periods increased cardiometabolic risk and altered aortic histomorphometry in rats.

ABSTRACT

Introduction: High-Intensity Interval Training (HIIT) involves developing exercises in short periods of time with high intensity, followed by periods of rest between the series of exercises performed, and is considered an important tool to combat obesity. Therefore, the present work aimed to identify the effects of high-intensity intermittent training on the lipid profile in overweight and obese university students. Materials and methods: quasi-experimental study, consisting of a sample of 30 students, who were randomly assigned into two groups of 15 students, thus leaving a control group (continuous training): 15 and an experimental group (intermittent exercise of high intensity: 15. Moreover, there were carried out Laboratory tests before and after training to find the lipid profile. Also, the realization of 20 training sessions, which were distributed three times a week, with an average duration of 50 minutes. Additionally, the performed of statistical tests with a level of statistical significance of p <0.05. Results: there is a statistically significant relationship in the HDL value of the control and experimental group. The Glucose values show statistically significant relationships in the experimental group (p = 0.001). Conclusions: Intermittent high-intensity training and continuous moderate-intensity work generate a decrease in LDL and Triglycerides variables and an increase in HDL. However, they are not statistically significant after 20 training sessions. However, high-intensity intermittent training results in glucose-lowering in overweight and obese people.

ABSTRACT

Background: This research was motivated by the complaints of tomato farmers about their crops that quickly rotted before being sold, as well as the many research results (raw materials and methods) that edible coating films could not be applied optimally. Objectives: The research was a practical recommendation by comparing the effectiveness of raw materials (polysaccharides, proteins, and lipids) with the dipping and spray methods. Materials and methods used in the comparison process were the application of Structural Equation Modeling (SEM) with the Partial Least Square (PLS) approach. Results: Dipping has a strong effect (f2 ≥ 0.35; p<0.05), while spray had a moderate effect (f2: 0.15-0.35; p<0.05). Thus, the role of dipping as a mediator was more dominant than spray. Compared to proteins and lipids, polysaccharides had the best effectiveness (ß:0.460-0.584; f2: 0.15-0.35; p<0.05). Conclusion: the three ingredients improved the quality of tomatoes, and the dipping method was easier to apply by farmers than the spray method, which had many obstacles in its application


Antecedentes: esta investigación está motivada por las quejas de los productores de tomate sobre sus cultivos que se pudren rápidamente antes de ser vendidos, así como por los muchos resultados de la investigación (materias primas y métodos) de que las películas de recubrimiento comestibles no se pudieron aplicar de manera óptima. Objetivos: La investigación consiste en recomendaciones prácticas mediante la comparación de la eficacia de las materias primas (polisacáridos, proteínas y lípidos) con los métodos de inmersión y aspersión. Métodos: El método utilizado en el proceso de comparación es la aplicación del modelo de ecuaciones estructurales (SEM) con el enfoque de mínimos cuadrados parciales (PLS). Resultados: La inmersión tiene un efecto fuerte (f2 ≥ 0,35; p<0,05), mientras que la pulverización tiene un efecto moderado (f2: 0,15-0,35; p<0,05). Por lo tanto, el papel de la inmersión como mediador es más dominante que el del rociado. Los polisacáridos tienen la mejor eficacia (ß:0,460-0,584; f2: 0,15-0,35; p<0,05) en comparación con las proteínas y los lípidos. Conclusión: es que los tres ingredientes pueden mejorar la calidad de los tomates, y el método de inmersión es más fácil de aplicar por los agricultores que el método de aspersión, que tiene muchos obstáculos en su aplicación

ABSTRACT

La difenhidramina tiene efectos antihistamínico anti-H1 específico y antimuscarínico que pueden ocasionar un desenlace fatal según la dosis total ingerida. Se reporta un caso de intoxicación por difenhidramina tratado de forma exitosa con emulsiones lipídicas a pesar de ingesta de dosis letal. Se presenta el caso de un paciente de 19 años que ingresó por intoxicación por difenhidramina a dosis de 25 mg/kg (1.5 g) después del tiempo de descontaminación, con toxidrome anticolinérgico, con neurotoxicidad, cardiotoxicidad (QRS y QT prolongados) y sin respuesta al enfoque inicial, se iniciaron emulsiones lipídicas y, a su vez, se logró alta temprana por evolución clínica favorable y resolución de la prolongación del intervalo QTc y del cuadro anticolinérgico. La emulsión lipídica es una opción terapéutica para disminuir la morbimortalidad y la estancia hospitalaria por contrarrestar la cardiotoxicidad y neurotoxicidad producidas por moléculas lipofílicas como la difenhidramina.


Diphenhydramine has specific anti-H1 antihistamine and antimuscarinic effects that can be fatal depending on the total dose ingested. A case of diphenhydramine poisoning successfully treated with lipid emulsions despite ingesting a lethal dose is presented. We present the case of a 19-year-old patient who was admitted for diphenhydramine intoxication at a dose of 25 mg/kg (1.5 g) after the decontamination time, with anticholinergic toxidrome, with neurotoxicity, cardiotoxicity (prolonged QRS and QT) and without response to initial approach. Lipid emulsions were started and, in turn, early discharge was achieved due to favorable clinical evolution and resolution of the prolongation of the QTc interval and the anticholinergic symptoms. Lipid emulsion is a therapeutic option to reduce morbidity and mortality and hospital stay by counteracting cardiotoxicity and neurotoxicity produced by lipophilic molecules such as diphenhydramine.


A difenidramina tem efeitos anti-histamínicos e antimuscarínicos anti-H1 específicos que podem ser fatais dependendo da dose total ingerida. Relata-se um caso de intoxicação por difenidramina tratada com sucesso com emulsões lipídicas apesar da ingestão de uma dose letal. Apresentamos o caso de uma paciente de 19 anos que foi internada por intoxicação por difenidramina na dose de 25 mg/kg (1,5 g) após o tempo de des-contaminação, com toxina anticolinérgica, neurotoxicidade, cardiotoxicidade (QS e QT prolongados) e sem resposta na abordagem inicial, iniciaram-se emulsões lipídicas e, por sua vez, obteve-se alta precoce devido à evolução clínica favorável e resolução do prolongamento do intervalo QTc e dos sintomas anticolinérgicos. A emulsão lipídica é uma opção terapêutica para reduzir a morbimortalidade e o tempo de internação por neutralizar a cardiotoxicidade e a neurotoxicidade produzidas por moléculas lipofílicas como a difenidramina.

ABSTRACT

O descarte inadequado de medicamentos pode levar a impactos ambientais negativos e deve ser considerado um problema de saúde pública. O presente estudo teve como objetivo levantar dados quantitativos e qualitativos relacionados ao perfil dos medicamentos descartados no município de Governador Valadares - MG. O trabalho foi desenvolvido nas UAPS/ESF que possuíam farmácias, e também na Farmácia Central/Policlínica Municipal. Nesses locais, foi realizada uma análise dos medicamentos descartados no período de julho de 2017 a maio de 2018. Por meio dos dados obtidos nesse período foi possível perceber que as principais classes de medicamentos descartadas foram os inibidores da enzima conversora de angiotensina, antagonistas da angiotensina II, agentes betabloqueadores, diuréticos, hipoglicemiantes, contraceptivos hormonais e agentes modificadores de lipídeos. Além disso, foi realizada uma ação de educação em saúde e aplicado um questionário semiestruturado aos usuários participantes dos grupos operativos. Dos 34 usuários respondentes do questionário, 23 (69,70%) não tinham acesso a informação sobre o local correto de descarte e armazenamento de medicamentos. Após a ação de educação em saúde verificou-se um aumento no quantitativo de medicamentos descartados pelos usuários nas UAPS/ESF Mãe de Deus I e II, Altinópolis III e IV, Santa Rita II, São Pedro I e II e Esperança e Nossa Senhora das Graças. O trabalho desenvolvido permitiu apresentar dados relevantes para a gestão municipal demonstrando a importância do farmacêutico no cuidado em saúde e o caráter epidemiológico local da prevalência das doenças crônico não transmissíveis.


The inadequate disposal of drugs can lead to negative environmental impacts and should be treated as a public health problem. This study aimed at surveying quantitative and qualitative data related to the profile of drugs discarded in the city of Governador Valadares - MG. The work was developed in the UAPS / ESF that had pharmacies, and also in the Central Pharmacy/Municipal Polyclinic. In these locations, an analysis of the drugs discarded between July 2017 and May 2018 was carried out. Through the data obtained in this period, it was possible to notice that the main classes of drugs discarded were angiotensin-converting enzyme inhibitors, angiotensin II antagonists, beta-blocking agents, diuretics, hypoglycemic agents, hormonal contraceptives, and lipid-modifying agents. In addition, a health education action was carried out and a semi-structured questionnaire was applied to users participating in the operating groups. From the 34 users who responded the questionnaire, 23 (69.70%) did not have access to information on the correct place to dispose and store medicines. After the health education action, there was an increase in the amount of drugs discarded by users in the UAPS/ESF Mãe de Deus I and II, Altinópolis III and IV, Santa Rita II, São Pedro I and II, and Esperança and Nossa Senhora das Graças. The work carried out made it possible to present relevant data for municipal management, demonstrating the importance of the pharmacist in health care and the local epidemiological character of the prevalence of chronic non-communicable diseases.

ABSTRACT

O objetivo deste estudo foi avaliar o efeito da aplicação de hormônio do crescimento (Growth Hormone - GH) e treinamento de força (TF) na composição do tecido ósseo de ratos Wistar a partir da Espectroscopia Raman. 40 ratos machos foram distribuídos de forma aleatória em quatro grupos: controle (C [n=10]), controle a aplicação de GH (GHC [n=10]), treinamento de força (T [n=10]) e treinamento de força e aplicação de GH (GHT [n=10]). O treinamento foi composto por quatro séries de 10 saltos aquáticos, realizados três vezes por semana, com sobrecarga correspondente a 50% do peso corpóreo e duração de quatro semanas. O GH foi aplicado na dose de 0,2 UI/Kg em cada animal, três vezes por semana e em dias alternados. Ao final do experimento, os animais foram eutanasiados e coletados os fêmures direitos para realização da análise da composição óssea. A espectroscopia Raman (ER) foi utilizada para observar os seguintes compostos a partir de suas respectivas bandas: colágeno e fosfolipídio (1445 cm-1), colesterol (548 cm-1), glicerol (607 cm-1), glicose (913 cm-1), Pico de carboidrato (931 cm-1 ) e prolina (918 cm-1 ). Para a análise estatística, foram realizados os testes de normalidade de Shapiro-Wilk e análise de variâncias ANOVA one-way, seguida pelo pós-teste de Tukey. Os resultados revelaram aumento nas concentrações de colágeno e fosfolipidio, colesterol, glicerol, glicose, pico de carboidrato e prolina em todos os grupos experimentais, associados ou não à realização do ST e/ou aplicação de GH. Porém, somente o grupo T diferiu significativamente do grupo C (p<0,05). Conclui-se que todas intervenções puderam promover ganho no tecido ósseo, porém, somente o grupo T demonstrou diferença significativa nos compostos minerais analisados. (AU)


The objective of this study was to evaluate the effect of the application of growth hormone (GH) and strength training (TF) on the bone tissue composition of Wistar rats using Raman Spectroscopy. 40 male rats were randomly assigned to four groups: control (C [n = 10]), control the application of GH (GHC [n = 10]), strength training (T [n = 10]) and training of strength and application of GH (GHT [n = 10]). The training consisted of four series of 10 water jumps, performed three times a week, with an overload corresponding to 50% of body weight and lasting four weeks. GH was applied at a dose of 0.2 IU / kg to each animal, three times a week and on alternate days. After four weeks, the animals were euthanized and the right femurs were collected to carry out the analysis of the bone composition. Raman spectroscopy (ER) was used to observe the following compounds from their respective bands: collagen and phospholipid (1445 cm-1), cholesterol (548 cm-1), glycerol (607 cm-1), glucose (913 cm-1), Peak carbohydrate (931 cm-1), proline (918 cm-1). For statistical analysis, the Shapiro-Wilk normality tests and ANOVA One-Way analysis of variances were performed, followed by the Tukey post-test. The results revealed an increase in the concentrations of collagen and phospholipid, cholesterol, glycerol, glucose, peak carbohydrate and proline in all experimental groups, associated or not with the performance of ST and / or application of GH. However, only group T differed significantly from group C (p <0.05). It was concluded that all intervention could promote gain in bone tissue, however, only the T group showed a significant difference in the analyzed mineral compounds. (AU)

ABSTRACT

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

ABSTRACT

ABSTRACT Objective To investigate the relationship between calcidiol (25(OH)D3) concentrations and iron parameters in patients with chronic kidney disease. Methods This is a cross-sectional, descriptive, and quantitative study. The sample consisted of 86 adult patients of both sexes undergoing dialysis. 25(OH)D3 concentrations were determined by chemiluminescence; food consumption was assessed using 24-hour recalls, and the serum levels of hemoglobin, iron, ferritin, and transferrin saturation were assessed. Data analysis was performed using the program Stata, with a significance level of p<0.05. Results The results pointed to 25(OH)D3 concentrations compatible with sufficiency, iron levels consistent with normality, and ferritin and transferrin saturation above the reference values. The consumption of carbohydrates and lipids was higher in females. There was no relationship between the adequacy of 25(OH)D3 and the presence of anemia and iron parameters. Conclusion Considering that the mean serum levels of iron and 25(OH)D3 were adequate, it is suggested that resistance to erythropoietin and the inflammatory process may have contributed to the percentage of anemic individuals found in the study.


RESUMO Objetivo Investigar a relação entre as concentrações de calcidiol (25(OH)D3) e os parâmetros de ferro em pacientes com doença renal crônica. Métodos É um estudo transversal, descritivo e quantitativo. A amostra foi composta por 86 pacientes, adultos, de ambos os sexos, em terapia dialítica. As concentrações de 25(OH)D3 foram determinadas pelo método de quimioluminescência; o consumo alimentar foi avaliado pela aplicação de Recordatórios de 24 horas e foram avaliados os níveis séricos de hemoglobina, ferro, ferritina e saturação de transferrina. A análise dos dados foi realizada no programa Stata, com nível de significância p<0.05. Resultados Os resultados apontaram para concentrações de 25(OH)D3 compatíveis com suficiência, níveis de ferro compatíveis com a normalidade e ferritina e saturação de transferrina superiores à referência. O consumo de carboidratos e lipídios foi superior no sexo feminino. Não foi verificada relação entre a adequação de 25(OH)D3 e a presença de anemia e parâmetros de ferro. Conclusão Tendo em vista que os níveis médios séricos de ferro e 25(OH)D3 estavam adequados, sugere-se que a resistência à eritropoietina e o processo inflamatório podem ter contribuído para o percentual de anêmicos constatado no estudo.

ABSTRACT

OBJECTIVE@#To explore the mechanism underlying the hepatoprotective effect of dihydromyricetin (DMY) against lipid accumulation in light of the lipophagy pathway and the inhibitory effect of DMY on HepG2 cell proliferation.@*METHODS@#LO2 cells were cultured in the presence of 10% FBS for 24 h and treated with 100 μg/mL DMY, or exposed to 50% FBS for 24 h followed by treatment with 50, 100, or 200 μg/mL DMY; the cells in recovery group were cultured in 50% FBS for 24 h and then in 10% FBS for another 24 h. Oil red O staining was used to observe the accumulation of lipid droplets in the cells, and the levels of TC, TG, and LDL and activities of AST, ALT and LDH were measured. The expression of LC3 protein was detected using Western blotting. AO staining and transmission electron microscopy were used to determine the numbers of autophagolysosomes and autophagosomes, respectively. The formation of autophagosomes was observed with MDC staining, and the mRNA expression levels of LC3, ATG7, AMPK, mTOR, p62 and Beclin1 were determined with q-PCR. Flow cytometry was performed to analyze the effect of 50, 100, and 200 μg/mL DMY on cell cycle and apoptosis of HepG2 cells; DNA integrity in the treated cells was examined with cell DNA fragmentation test.@*RESULTS@#DMY treatment and pretreatment obviously inhibited lipid accumulation and reduced the levels of TC, TG, LDL and enzyme activities of AST, ALT and LDH in LO2 cells (P < 0.05). In routinely cultured LO2 cells, DMY significantly promoted the formation of autophagosomes and autophagolysosomes and upregulated the expression of LC3 protein. DMY obviously attenuated high FBS-induced inhibition of autophagosome formation in LO2 cells, up- regulated the mRNA levels of LC3, ATG7, Beclin1 and AMPK, and downregulated p62 and mTOR mRNA levels (P < 0.05 or 0.01). In HepG2 cells, DMY caused obvious cell cycle arrest, inhibited cell proliferation, and induced late apoptosis and DNA fragmentation.@*CONCLUSION@#DMY reduces lipid accumulation in LO2 cells by regulating the AMPK/ mTOR-mediated lipophagy pathway and inhibits the proliferation of HepG2 by causing cell cycle arrest and promoting apoptosis.

ABSTRACT

OBJECTIVE@#To investigate the inhibitory effect of RSL3 on the proliferation, invasion and migration of cisplatinresistant testicular cancer cells (I-10/DDP) and the effect of carbenoxolone on the activity of RSL3 against testicular cancer.@*METHODS@#MTT assay was used to evaluate the survival rate of I-10/DDP cells following treatment with RSL3 (1, 2, 4, 8, 16 or 32 μmol/L) alone or in combination with carbenoxolone (100 μmol/L) or after treatment with Fer-1 (2 μmol/L), RSL3 (4 μmol/L), RSL3+Fer-1, RSL3+carbenoxolone (100 μmol/L), or RSL3+Fer-1+carbenoxolone. Colony formation assay was used to assess the proliferation ability of the treated cells; wounding-healing assay and Transwell assay were used to assess the invasion and migration ability of the cells. The expression of GPX4 was detected using Western blotting, the levels of lipid ROS were detected using C11 BODIPY 581/591 fluorescent probe, and the levels of Fe2+ were determined with FerroOrange fluorescent probe.@*RESULTS@#RSL3 dose-dependently decreased the survival rate of I-10/DDP cells, and the combined treatment with 2, 4, or 8 μmol/L RSL3 with carbenoxolone, as compared with RSL3 treatment alone, resulted in significant reduction of the cell survival rate. The combination with carbenoxolone significantly enhanced the inhibitory effect of RSL3 on colony formation, wound healing rate (P=0.005), invasion and migration of the cells (P < 0.001). Fer-1 obviously attenuated the inhibitory effects of RSL3 alone and its combination with carbenoxolone on I-10/DDP cells (P < 0.01). RSL3 treatment significantly decreased GPX4 expression (P=0.001) and increased lipid ROS level (P=0.001) and Fe2+ level in the cells, and these effects were further enhanced by the combined treatment with carbenoxolone (P < 0.01).@*CONCLUSION@#Carbenoxolone enhances the inhibitory effect of RSL3 on the proliferation, invasion and migration of cisplatin-resistant testicular cancer cells by promoting RSL3-induced ferroptosis.

ABSTRACT

Objective: To investigate the effect of visceral fat area (VFA) on the surgical efficacy and early postoperative complications of radical gastrectomy for gastric cancer. Methods: A retrospective cohort study method was used. Clinicopathological data and preoperative imaging data of 195 patients who underwent D2 radical gastric cancer surgery at the First Affiliated Hospital of Xi'an Jiaotong University from January 2014 to December 2017 were analyzed retrospectively. Inclusion criteria: (1) complete clinicopathological and imaging data; (2) malignant gastric tumor diagnosed by preoperative pathology, and gastric cancer confirmed by postoperative pathology; (3) no preoperative complications such as bleeding, obstruction or perforation, and no distant metastasis. Those who had a history of abdominal surgery, concurrent malignant tumors, poor basic conditions, emergency surgery, palliative resection, and preoperative neoadjuvant therapy were excluded. The VFA was calculated by software and VFA ≥ 100 cm2 was defined as visceral obesity according to the Japan Obesity Association criteria . The patients were divided into high VFA (VFA-H, VFA≥100 cm2, n=96) group and low VFA (VFA-L, VFA<100 cm2, n=99) group . The clinicopathological characteristics, surgical outcomes and early postoperative complications were compared between the two groups. Univariate and multivariate Logistic regression models were used to analyze the risk factors of early complications. Receiver operating characteristic (ROC) curve was used to analyze predictive values of VFA for early complications. Pearson's χ2 test was used to analyze the correlation between BMI and VFA. Results: There were no significant differences in terms of gender, age, American Society of Anesthesiologists physical status classification, preoperative comorbidities, preoperative anemia, tumor TNM staging, N staging, T staging and tumor differentiation, surgical method, extent of resection, and tumor location between the VFA-L group and the VFA-H group (all P>0.05). However, patients in the VFA-H group had higher BMI, larger tumor, lower rate of hypoalbuminemia and greater subcutaneous fat area (SFA) (all P<0.05). The VFA-H group presented significantly longer operation time and significantly less number of harvested lymph nodes as compared to the VFA-L group (both P<0.05). However, there were no significant differences in intraoperative blood loss, conversion to laparotomy and postoperative hospital stay (all P>0.05). Complications of Clavien-Dindo grade II and above within 30 days after operation were mainly anastomosis-related complications (leakage, bleeding, infection and stricture), intestinal obstruction and incision infection. The VFA-H group had a higher morbidity of early complications compared to the VFA-L group [24.0% (23/96) vs 10.1% (10/99), χ2=6.657, P=0.010], and the rates of anastomotic complications and incision infection were also higher in the VFA group [10.4% (10/96) vs. 3.0% (3/99), χ2=4.274, P=0.039; 7.3% (7/96) vs. 1.0% (1/99), P=0.033]. Multivariate logistic analysis showed that high BMI (OR=3.688, 95%CI: 1.685-8.072, P=0.001) and high VFA (OR=2.526, 95%CI: 1.148-5.559,P=0.021) were independent risk factors for early complications. The area under the ROC curve (AUC) of VFA for predicting early complications was 0.645, which was higher than that of body weight (0.591), BMI (0.624) and SFA (0.626). Correlation analysis indicated that there was a significantly positive correlation between BMI and VFA (r=0.640, P<0.001). Conclusion: VFA ≥ 100 cm2 is an independent risk factor for early complications after radical gastrectomy for gastric cancer.It can better predict the occurrence of above early postoperative complications.

ABSTRACT

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.

ABSTRACT

Objective: To evaluate the effects of a high-protein diet on anthropometric indices and blood lipid in overweight and obese children and provide evidence for their dietary management. Methods: This was a Meta-analysis. The randomized controlled trials on the effects of a high-protein diet on anthropometric indices and blood lipid in overweight and obese children published up to January 19, 2022 were searched in PubMed, Web of Science, Embase, Cochrane Library and CNKI database, with the key words of "child" "adolescent" "obesity" "overweight" "pediatric obesity" "weight loss" "dietary protein" "dietary carbohydrate" "caloric restrict" both in English and Chinese. The quality of the included literature was evaluated according to the "risk of bias" assessment tool, which included bias from the randomization process, deviation from intended interventions, missing outcome data, measurement of the outcome and selection of the reported results. Moreover, calculated the pooled mean difference, perform heterogeneity test, and assess publication bias. Results: A total of 8 articles were selected from the retrieved 4 836 articles, all in English. The sample sizes ranged from 4 to 120. The analysis showed that the post-intervention body mass index (mean difference (MD)=-0.66, 95%CI -1.76-0.44), body mass index Z-scores (MD=-0.09, 95%CI-0.23-0.05), fat content percentage (MD=-1.07, 95%CI-2.88-0.74), high density lipoprotein (MD=0.02, 95%CI-0.02-0.06) and low density lipoprotein (MD=0.04, 95%CI-0.08-0.17) were not significantly different with those of the standard protein diet group, with P values being 0.240, 0.220, 0.250, 0.360 and 0.480, respectively. Subgroup analysis showed that after excluding one study, the difference in body mass index between the short-term intervention group and control group was statistically significant (MD=-1.60, 95%CI-3.14--0.06, P=0.040). Conclusions: A short-term high-protein diet intervention seems to improve the body mass index status of overweight and obese children. Nevertheless, a high-protein diet does not affect any other selected anthropometric indices and blood lipids. More studies with large sample sizes, higher quality and comparable standard of high-protein diet are needed for further demonstration.

ABSTRACT

OBJECTIVE@#To assess the influence of apolipoprotein E (ApoE) gene polymorphisms on the therapeutic effect of lipid-lowering statins in patients with ischemic cerebral infarction.@*METHODS@#One hundred and six patients with ischemic cerebral infarction who orally took lipid-lowering statins for 3 months were enrolled. Changes in serum triacylglycerol (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) before and after the drug administration were analyzed. ApoE gene polymorphisms were detected by real-time fluorescent quantitative PCR, and genotypes of ApoE gene in patients with different effects were compared.@*RESULTS@#The detection rates for E2/E2, E2/E3, E3/E3, E2/E4 and E3/E4 genotypes were 0.94%, 11.32%, 63.21%, 1.89% and 22.64%, respectively. And the detection rates for E2, E3 and E4 alleles were 7.55%, 80.19% and 12.26%, respectively. Biochemical phenotypes included E2 type (13 cases, 12.26%), E3 type (69 cases, 65.09%) and E4 type (24 cases, 22.65%). Before administration, TG and TC of E2 type were the highest (P<0.05), but no significant difference was detected in HDL-C and LDL-C among the three phenotypes (P>0.05).Following the drug administration, TG, TC and LDL-C were decreased, while HDL-C was increased. HDL-C of E2 type was the highest, TC and LDL-C of E4 type were the highest (P<0.05). The E3/E3 ratio in low-efficiency group at admission was lower than that in the high-efficiency group, while the E3/E4 ratio was higher than that in the high-efficiency group (P<0.05). The proportion of E3 allele in low-efficiency group was lower than that in high-efficiency group, while the proportion of E4 allele was higher than that in high-efficiency group (P<0.05).@*CONCLUSION@#ApoE gene polymorphisms are closely correlated with the therapeutic effect of lipid-lowering statins in patients with ischemic cerebral infarction. The lipid-lowering effects are more significant in patients with E2 and E3 genotypes, but were poor in those with the E4 genotype. Personalized regimens should be applied.

ABSTRACT

Liposomes with precisely controlled composition are usually used as membrane model systems to investigate the fundamental interactions of membrane components under well-defined conditions. Hydration method is the most common method for liposome formation which is found to be influenced by composition of the medium. In this paper, the effects of small alcohol (ethanol) on the hydration of lipid molecules and the formation of liposomes were investigated, as well as its coexistence with sodium chloride. It was found that ethanol showed the opposite effect to that of sodium chloride on the hydration of lipid molecules and the formation of liposomes. The presence of ethanol promoted the formation of liposomes within a certain range of ethanol content, but that of sodium chloride suppressed the liposome formation. By investigating the fluorescence intensity and continuity of the swelled membranes as a function of contents of ethanol and sodium chloride, it was found that sodium chloride and ethanol showed the additive effect on the hydration of lipid molecules when they coexisted in the medium. The results may provide some reference for the efficient preparation of liposomes.

ABSTRACT

This study selected three typical Chinese herbs with cold property(Rhei Radix et Rhizoma, Scutellariae Radix, and Coptidis Rhizoma) and another three with heat property(Cinnamomi Cortex, Zingiberris Rhizoma, and Aconiti Lateralis Radix Praeparata) to observe their regulatory effects on metabolism in animal organism, especially on lipid and energy metabolism in mice after a short-(7 d) and long-term(35 d) intervention. The mRNA expression levels of lipid metabolism genes in epididymal adipose tissue and liver were determined by real-time PCR. The oxygen consumption, carbon dioxide production, and energy consumption were detected by metabolic system. After the short-term intervention, the Chinese herbs with heat property significantly reduced epididymal adipose tissue index and elevated the expression levels of acetyl-CoA carboxylase(ACC), lipoprotein lipase(LPL), and carnitine-palmityl transferase 1(CPT-1) in liver and epididymal adipose tissues. However, those with cold property promoted the expression of above-mentioned genes in epididymal adipose tissue. After the long-term intervention, cold and heat Chinese herbs had no significant effect on epididymal adipose tissue index of animals, while cold Chinese herbs could increase carbon dioxide production and energy consumption and reduce activity. These findings demonstrated that the short-term intervention effects of cold and heat Chinese herbs on animal metabolism were significantly stronger than the long-term intervention effects. Specifically, the short-term intervention with cold Chinese herbs enhanced the lipid metabolism in epididymal adipose tissue, while the heat Chinese herbs promoted lipid metabolism in epididymal adipose tissue and liver. The long-term intervention with cold and heat Chinese herbs resulted in no obvious change in lipid level, but long-term intervention with cold Chinese herbs accelerated energy consumption of the body. This study preliminarily observed the effects of cold and heat Chinese herbs on normal animal physiology from lipid and energy metabolism, which would provide reference for explaining the biological basis of Chinese herbs with cold or heat property based on biological response.

ABSTRACT

The present study investigated the therapeutic effect and mechanism of Di'ao Xinxuekang(DXXK) on non-alcoholic steatohepatitis(NASH) in mice. Sixty-five C57 BL/6 J mice were randomly divided into a normal group and an experimental group for model induction with the high-fat diet for 16 weeks. Then the mice in the experimental group were randomly divided into a model group, an atorvastatin group(4 mg·kg~(-1)·d~(-1)), and high-(200 mg·kg~(-1)·d~(-1)), medium-(60 mg·kg~(-1)·d~(-1)), and low-dose(20 mg·kg~(-1)·d~(-1)) DXXK groups, with 10 mice in each group. Drugs were administered by gavage for eight weeks. Serum lipid, liver lipid, serum alanine aminotransferase(ALT), aspartate aminotransferase(AST), malondialdehyde(MDA), superoxide dismutase(SOD), and glutathione reductase(GSH-Px) were determined. Interleukin-1β(IL-1β) and tumor necrosis factor-α(TNF-α) were measured by enzyme-linked immunosorbent assay(ELISA). The liver index was calculated. The liver pathological change and lipid accumulation were observed by HE and oil red O staining. The liver ultrastructure was observed by the transmission electron microscope. The mRNA and protein expression of nuclear factor-erythroid 2 related factor 2(Nrf2) and heme oxygenase-1(HO-1) was detected by real-time fluorescence-based quantitative PCR and Western blot, respectively. The results showed that compared with the normal group, the model group displayed serum lipid and liver lipid metabolism disorders, elevated transaminase, lipid deposition, steatosis, and inflammation, suggesting that the NASH model in mice was properly induced. Compared with the model group, the DXXK groups showed decreased serum lipid, liver lipid, ALT, AST, MDA, IL-1β, and TNF-α, increased SOD and GSH-Px, alleviated hepatic steatosis, ballooning, and inflammation, and up-regulated Nrf2 and HO-1 gene and protein expression. In conclusion, DXXK can significantly alleviate NASH in mice, which is related to the inhibition of oxidative stress and inflammatory damage by up-regulating the Nrf2/HO-1 signaling pathway.

ABSTRACT

Emodin nanostructured lipid carriers(ED-NLC) were prepared and their quality was evaluated in vitro. Based on the results of single-factor experiments, the ED-NLC formulation was optimized by Box-Behnken response surface method with the dosages of emodin, isopropyl myristate and poloxamer 188 as factors and the nanoparticle size, encapsulation efficiency and drug loading as evaluation indexes. Then the evaluation was performed on the morphology, size and in vitro release of the nanoparticles prepared by emulsification-ultrasonic dispersion method in line with the optimal formulation, i.e., 3.27 mg emodin, 148.68 mg isopropyl myristate and 173.48 mg poloxamer 188. Under a transmission electron microscope(TEM), ED-NLC were spherical and their particle size distribution was uniform. The particle size of ED-NLC was(97.02±1.55) nm, the polymer dispersion index 0.21±0.01, the zeta potential(-38.96±0.65) mV, the encapsulation efficiency 90.41%±0.56% and the drug loading 1.55%±0.01%. The results of differential scanning calorimeter(DSC) indicated that emodin may be encapsulated into the nanostructured lipid carriers in molecular or amorphous form. In vitro drug release had obvious characteristics of slow release, which accorded with the first-order drug release equation. The fitting model of Box-Behnken response surface methodology was proved accurate and reliable. The optimal formulation-based ED-NLC featured concentrated particle size distribution and high encapsulation efficiency, which laid a foundation for the follow-up study of ED-NLC in vivo.
