ABSTRACT

Abstract Introduction: Glyphosate is the most widely used herbicide worldwide and in Brazil. There is currently increasing concern about the effects of glyphosate on human health. The Brazilian Institute for Consumer Protection showed data on the presence of glyphosate in some of Brazil's most consumed ultra-processed products. Currently, regulations on the upper limit for these residues in ultra-processed foods have yet to be established by the National Health Surveillance, and ultra-processed food consumption is independently associated with an increased risk of incident chronic kidney disease. Methods: Since an unbalanced diet can interfere with kidney function, this study aims to investigate the effect of daily intake of 5 mg/kg bw glyphosate in conjunction with a balanced diet and the possible impact on renal function in rats. Kidney function, kidney weight, markers of renal injury, and oxidative stress were evaluated. Results: There was a decrease in kidney weight. The main histopathological alterations in renal tissues were vacuolation in the initial stage and upregulation of the kidney injury marker KIM-1. Renal injury is associated with increased production of reactive oxygen species in mitochondria. Conclusion: This study showed changes in the kidney of rats exposed to a balanced diet with glyphosate, suggesting a potential risk to human kidney. Presumably, ultra-processed food that contain glyphosate can potentiate this risk. The relevance of these results lies in drawing attention to the need to regulate glyphosate concentration in ultra-processed foods in the future.


RESUMO Introdução: O glifosato é o herbicida mais utilizado no mundo e no Brasil. Atualmente, há uma preocupação crescente com os efeitos do glifosato na saúde humana. O Instituto Brasileiro de Defesa do Consumidor apresentou dados sobre a presença de glifosato em alguns dos produtos ultraprocessados mais consumidos no Brasil. Atualmente, as regulamentações sobre o limite máximo desses resíduos em alimentos ultraprocessados ainda não foram estabelecidas pela Vigilância Sanitária Nacional, e o consumo de alimentos ultraprocessados está indepen­dentemente associado a um risco maior de doença renal crônica incidente. Métodos: Como uma dieta desbalanceada pode interferir na função renal, este estudo tem como objetivo investigar o efeito da ingestão diária de 5 mg/kg pc de glifosato em conjunto com uma dieta equilibrada e o possível impacto na função renal em ratos. Foram avaliados função renal, peso dos rins, marcadores de lesão renal e estresse oxidativo. Resultados: Houve redução no peso dos rins. As principais alterações histopatológicas nos tecidos renais foram vacuolização no estágio inicial e regulação positiva do marcador de lesão renal KIM-1. A lesão renal está associada à produção aumentada de espécies reativas de oxigênio nas mitocôndrias. Conclusão: Esse estudo mostrou alterações nos rins de ratos expostos a uma dieta balanceada com glifosato, sugerindo um risco potencial ao rim humano. Presumivelmente, alimentos ultraprocessados que contenham glifosato podem potencializar esse risco. A relevância desses resultados está no fato de chamar a atenção para a necessidade de regulamentar a concentração de glifosato em alimentos ultraprocessados no futuro.

ABSTRACT

SUMMARY: Traumatic ankle osteoarthritis is a degenerative condition resulting from traumatic injuries. The objective of this study was to evaluate the impact of minimally invasive ankle joint fusion surgery on ankle function, oxidative damage, and inflammatory factor levels in traumatic ankle osteoarthritis patients. A total of 112 traumatic ankle osteoarthritis patients treated in our hospital from January 2022 to January 2023 were enrolled. They were randomly rolled into a control group (Group C) and an experimental group (Group E), with the former undergoing conventional open ankle joint fusion surgery and the latter receiving minimally invasive ankle joint fusion surgery. A comparison was made between the two groups based on American Orthopedic Foot and Ankle Society (AOFAS), bony fusion rates, and visual analog scale (VAS) scores at pre-operation, and at 1, 2, and 3 months post-operation. Additionally, serum oxidative damage indicators and inflammatory factor levels were measured to evaluate the recovery effects in both groups. Relative to Group C, Group E showed drastically increased AOFAS scores and bony fusion rates (P<0.05), as well as greatly decreased VAS scores (P<0.05). Moreover, Group E exhibited more pronounced improvements in oxidative damage indicators and inflammatory factors versus Group C (P<0.05). Minimally invasive ankle joint fusion surgery drastically improves ankle function in traumatic ankle osteoarthritis patients and reduces levels of oxidative damage and inflammatory response. This provides an important clinical treatment option.


La osteoartritis traumática del tobillo es una afección degenerativa resultante de lesiones traumáticas. El objetivo de este estudio fue evaluar el impacto de la cirugía mínimamente invasiva de fusión de la articulación talocrural sobre la función del tobillo, el daño oxidativo y los niveles de factor inflamatorio en pacientes con osteoartritis traumática del tobillo. Se inscribieron un total de 112 pacientes con artrosis traumática de tobillo tratados en nuestro hospital desde enero de 2022 hasta enero de 2023. Fueron divididos aleatoriamente en un grupo de control (Grupo C) y un grupo experimental (Grupo E), donde el primero se sometió a una cirugía de fusión de la articulación talocrural abierta convencional y el segundo recibió una cirugía de fusión de la articulación talocrural mínimamente invasiva. Se realizó una comparación entre los dos grupos según la Sociedad Estadounidense de Ortopedia de Pie y Tobillo (AOFAS), las tasas de fusión ósea y las puntuaciones de la escala visual analógica (EVA) antes de la operación y 1, 2 y 3 meses después de la operación. Además, se midieron los indicadores de daño oxidativo sérico y los niveles de factor inflamatorio para evaluar los efectos de la recuperación en ambos grupos. En relación con el grupo C, el grupo E mostró puntuaciones AOFAS y tasas de fusión ósea drásticamente aumentadas (P <0,05), así como puntuaciones VAS muy disminuidas (P <0,05). Además, el grupo E exhibió mejoras más pronunciadas en los indicadores de daño oxidativo y factores inflamatorios en comparación con el grupo C (P <0,05). La cirugía de fusión de la articulación talocrural mínimamente invasiva mejora drásticamente la función del tobillo en pacientes con osteoartritis traumática del tobillo y reduce los niveles de daño oxidativo y la respuesta inflamatoria. Esto proporciona una importante opción de tratamiento clínico.

ABSTRACT

Abstract Introduction: Nephrotic syndrome (NS) is one of the reasons of end-stage kidney disease, and elucidating the pathogenesis and offer new treatment options is important. Oxidative stress might trigger pathogenesis systemically or isolated in the kidneys. Octreotide (OCT) has beneficial antioxidant effects. We aimed to investigate the source of oxidative stress and the effect of OCT on experimental NS model. Methods: Twenty-four non-uremic Wistar albino rats were divided into 3 groups. Control group, 2 mL saline intramuscular (im); NS group, adriamycin 5 mg/kg intravenous (iv); NS treatment group, adriamycin 5 mg/kg (iv) and OCT 200 mcg/kg (im) were administered at baseline (Day 0). At the end of 21 days, creatinine and protein levels were measured in 24-hour urine samples. Erythrocyte and renal catalase (CAT) and thiobarbituric acid reactive substance (TBARS) were measured. Renal histology was also evaluated. Results: There was no significant difference among the 3 groups in terms of CAT and TBARS in erythrocytes. Renal CAT level was lowest in NS group, and significantly lower than the control group. In treatment group, CAT level significantly increased compared with NS group. In terms of renal histology, tubular and interstitial evaluations were similar in all groups. Glomerular score was significantly higher in NS group compared with control group and it was significantly decreased in treatment group compared to NS group. Conclusions: Oxidative stress in NS might be due to the decrease in antioxidant protection mechanism in kidney. Octreotide improves antioxidant levels and histology in renal tissue and might be a treatment option.


Resumo Introdução: Síndrome nefrótica (SN) é uma das causas de doença renal em estágio terminal. É importante elucidar a patogênese e oferecer novas opções de tratamento. Estresse oxidativo pode desencadear a patogênese sistemicamente ou isoladamente nos rins. O octreotide (OCT) tem efeitos antioxidantes benéficos. Nosso objetivo foi investigar a fonte de estresse oxidativo e efeito do OCT no modelo experimental de SN. Métodos: Dividimos 24 ratos albinos Wistar não urêmicos em 3 grupos. Grupo controle, 2 mL de solução salina intramuscular (im); grupo SN, adriamicina 5 mg/kg intravenosa (iv); grupo tratamento SN, adriamicina 5 mg/kg (iv) e OCT 200 mcg/kg (im) foram administrados no início do estudo (Dia 0). Aos 21 dias, mediram-se os níveis de creatinina e proteína em amostras de urina de 24 horas. Mediu-se a catalase (CAT) eritrocitária e renal e a substância reativa ao ácido tiobarbitúrico (TBARS). Avaliou-se também histologia renal. Resultados: Não houve diferença significativa entre os três grupos em termos de CAT e TBARS em eritrócitos. O nível de CAT renal foi menor no grupo SN e significativamente menor que no grupo controle. No grupo tratamento, o nível de CAT aumentou significativamente em comparação com o grupo SN. Quanto à histologia renal, as avaliações tubular e intersticial foram semelhantes em todos os grupos. O escore glomerular foi significativamente maior no grupo SN em comparação com o grupo controle e diminuiu significativamente no grupo de tratamento em comparação com o grupo SN. Conclusões: Estresse oxidativo na SN pode ser devido à diminuição do mecanismo de proteção antioxidante nos rins. O octreotide melhora níveis de antioxidantes e histologia do tecido renal e pode ser uma opção de tratamento.

ABSTRACT

Abstract The incidence of non-alcoholic fatty liver (NAFLD) remains high, and many NAFLD patients suffer from severe ischemia-reperfusion injury (IRI). Currently, no practical approach can be used to treat IRI. Puerarin plays a vital role in treating multiple diseases, such as NAFLD, stroke, diabetes, and high blood pressure. However, its role in the IRI of the fatty liver is still unclear. We aimed to explore whether puerarin could protect the fatty liver from IRI. C57BL/6J mice were fed with a high‐fat diet (HFD) followed by ischemia reperfusion injury. We showed that hepatic IRI was more severe in the fatty liver compared with the normal liver, and puerarin could significantly protect the fatty liver against IRI and alleviate oxidative stress. The PI3K-AKT signaling pathway was activated during IRI, while liver steatosis decreased the level of activation. Puerarin significantly protected the fatty liver from IRI by reactivating the PI3K-AKT signaling pathway. However, LY294002, a PI3K-AKT inhibitor, attenuated the protective effect of puerarin. In conclusion, puerarin could significantly protect the fatty liver against IRI by activating the PI3K-AKT signaling pathway.

ABSTRACT

SUMMARY: This study assessed the effects of Acacia Senegal (AS) combined with insulin on Na+/K+-ATPase (NKA) activity and mRNA expression, serum glucose, renal function, and oxidative stress in a rat model of diabetic nephropathy (DN). Sixty rats were equally divided into six groups: normal control, normal+AS, diabetic (DM), DM+insulin, DM+AS, and DM+insulin+AS groups. Diabetes mellitus (type 1) was induced by a single injection of streptozotocin (65 mg/kg), and insulin and AS treatments were carried until rats were culled at the end of week 12. Serum glucose and creatinine levels, hemoglobin A1c (HbA1c) were measured. Renal homogenate levels of NKA activity and gene expression, malondialdehyde, superoxide dismutase (SOD), catalase and reduced glutathione (GSH) were evaluated as well as kidney tissue histology and ultrastructure. Diabetes caused glomerular damage and modulation of blood and tissue levels of creatinine, glucose, HbA1c, malondialdehyde, NKA activity and gene expression, SOD, catalase and GSH, which were significantly (p<0.05) treated with AS, insulin, and insulin plus AS. However, AS+insulin treatments were more effective. In conclusion, combined administration of AS with insulin to rats with DN decreased NKA activity and gene expression as well as oxidative stress, and improved glycemic state and renal structure and function.


Este estudio evaluó los efectos de Acacia senegal (AS) combinada con insulina sobre la actividad Na+/K+- ATPasa (NKA) y la expresión de ARNm, la glucosa sérica, la función renal y el estrés oxidativo en un modelo de nefropatía diabética (ND) en ratas. Sesenta ratas se dividieron equitativamente en seis grupos: control normal, normal+AS, diabética (DM), DM+insulina, DM+AS y DM+insulina+AS. La diabetes mellitus (tipo 1) se indujo mediante una única inyección de estreptozotocina (65 mg/kg), y los tratamientos con insulina y AS se llevaron a cabo hasta que las ratas fueron sacrificadas al final de la semana 12. Se midieron niveles séricos de glucosa y creatinina, hemoglobina A1c (HbA1c). Se evaluaron los niveles de homogeneizado renal de actividad NKA y expresión génica, malondialdehído, superóxido dismutasa (SOD), catalasa y glutatión reducido (GSH), así como la histología y ultraestructura del tejido renal. La diabetes causó daño glomerular y modulación de los niveles sanguíneos y tisulares de creatinina, glucosa, HbA1c, malondialdehído, actividad y expresión génica de NKA, SOD, catalasa y GSH, los cuales fueron tratados significativamente (p<0,05) con AS, insulina e insulina más AS. Sin embargo, los tratamientos con AS+insulina fueron más efectivos. En conclusión, la administración combinada de AS con insulina a ratas con DN disminuyó la actividad de NKA y la expresión genética, así como el estrés oxidativo, y mejoró el estado glucémico y la estructura y función renal.

ABSTRACT

RESUMEN Objetivo: Identificar la influencia del consumo de hidratos de carbono (HCO) sobre el estado oxidante en mujeres con y sin diabetes mellitus gestacional (DMG). Materiales y métodos: Se realizó un estudio transversal, observacional y comparativo a dos grupos de 21 mujeres con y sin DMG, respectivamente, en la ciudad de Toluca, México, de enero a diciembre del 2022. Para evaluar parámetros sociodemográficos, se les aplicó un cuestionario de historia clínica; en cuanto a los parámetros antropométricos, se les midió peso corporal y estatura; y respecto a los parámetros bioquímicos, colesterol total (CT) y triglicéridos (TG). Para evaluar el estado oxidante/antioxidante se cuantificaron, como marcador oxidante, el malondihaldeído (MDA), y como antioxidantes, catalasa (cat), superóxido dismutasa (SOD) y capacidad antioxidante total (CAT). Los hábitos dietéticos se evaluaron a través de un recordatorio de 24 horas, en ambos grupos de mujeres, para obtener los macronutrientes: proteínas, lípidos e HCO. A partir de los hidratos de carbono totales (HCOT), se calcularon los hidratos de carbono complejos (HCOC) e hidratos de carbono simples (HCOS) como la sacarosa. Para el cálculo de HCOS por día, se usó la lista de alimentos con contenido de sacarosa por cada 100 gramos de consumo que emplea el Sistema Mexicano de Equivalentes; para el análisis de dieta, se utilizó el programa Nutrikcal VO. Se usaron las pruebas estadísticas t de Student para muestras independientes, U de Mann-Whitney para las variables no homogéneas y se realizó la correlación de Spearman (p < 0,05) en el programa SPSS, versión 19. Resultados: Los resultados mostraron que la diferencia entre los valores de CT (p < 0,029), TG (p < 0,029), las enzimas: cat (p < 0,011), SOD (p < 0,013), así como el MDA (p < 0,039), fueron significativamente mayores en las pacientes del grupo con DMG en comparación con el grupo sin DMG. Además, el grupo con DMG consumió mayor proporción de sacarosa. Conclusiones: Las mujeres con DMG tienen un desequilibrio en el estado oxidante/antioxidante influenciado por el tipo de HCO que consumen, en particular los HCOS como la sacarosa.


ABSTRACT Objective: To identify the influence of carbohydrate (CHO) intake on oxidative status among women with and without gestational diabetes mellitus (GDM). Materials and methods: A cross-sectional, observational and comparative study was carried out with two groups of 21 women each with and without GDM in the city of Toluca, Mexico, from January to December 2022. The sociodemographic parameters were determined by administering the patients a medical history questionnaire; anthropometric parameters such as body weight and height were measured; and biochemical parameters including total cholesterol (TC) and triglycerides (TG) were calculated. The oxidant/antioxidant status was assessed as follows: malondialdehyde (MDA) as oxidative stress marker; and catalase (CAT), superoxide dismutase (SOD) and total antioxidant capacity (TAC) as antioxidants. Dietary habits were evaluated through a 24-hour reminder in both groups of women to obtain the macronutrient classes, i.e., proteins, fats and CHOs. Based on the total carbohydrates (TCHOs), complex (CCHOs) and simple carbohydrates (SCHOs) such as sucrose were calculated. SCHOs per day were measured using the list of foods with sucrose content per 100 grams according to the Mexican Food Equivalence System (SMAE). The NutriKcal VO program was used for the dietary analysis. Statistical tests such as Student's t test and Mann-Whitney U test were performed for the independent samples and nonhomogeneous variables, respectively, and Spearman's rank correlation coefficient (p < 0.05) was determined using the IBM SPSS Statistics V19. Results: The results showed that the difference between the levels of TC (p < 0.029), TG (p < 0.029), enzymes CAT (p < 0.011) and SOD (p < 0.013), as well as MDA (p < 0.039) was significantly higher among patients in the group with GDM compared to that in the group without GDM. In addition, the group with GDM consumed a higher proportion of sucrose. Conclusions: Women with GDM have an imbalance in the oxidant/antioxidant status, influenced by the type of CHO they consume, particularly SCHOs such as sucrose.

ABSTRACT

ABSTRACT Purpose: This study aimed to determine the effect of serum G receptor-mediated protein-1 levels on the development of retinopathy in patients with diabetes in comparison with healthy individuals. Methods: The study enrolled patients with diabetic retinopathy (Group 1), patients without diabetic retinopathy (Group 2), and healthy individuals (Group 3). Levels of serum progesterone, serum G receptor-mediated protein-1, estradiol, oxidant/antioxidants, and thyroid-releasing hormones were analyzed and compared among the groups. Post-hoc analysis was performed to compare the subgroups in which significant differences were found. Results: Groups 1, 2, and 3 each included 40 patients. A significant difference was found among all groups in terms of serum G receptor-mediated protein-1, oxidant/antioxidant, and estradiol levels (p<0.01), but no significant difference was found in terms of thyroid-releasing hormone or progesterone (p=0.496, p=0.220, respectively). In the post-hoc analysis of the groups with significant differences, another significant difference was found among all groups for serum G receptor-mediated protein-1 and oxidant/antioxidant levels (p<0.05). Serum G receptor-mediated protein-1 and oxidant levels were positively correlated, whereas serum G receptor-mediated protein-1 and antioxidant levels were negatively correlated (r=0.622/p<0.01, r=0.453/p<0.01, r=0.460/p<0.01, respectively). The multiple regression analysis showed that increased levels of serum G receptor-mediated protein-1 may help prevent diabetic retinopathy. Conclusions: Serum G receptor-mediated protein-1 levels, which were the highest in the diabetic retinopathy Group, increased as the oxidant/antioxidant balance changed in favor of oxidative stress. This appears to be a defense mechanism for preventing neuronal damage.


RESUMO Objetivo: Esta pesquisa buscou determinar o im­pacto dos níveis de proteína G sérica no desenvolvimento da retinopatia em pacientes diabéticos, comparando-os a indivíduos saudáveis. Métodos: Foram incluídos, no estudo, 40 pacientes com retinopatia diabética (Grupo 1), 40 pacientes sem retinopatia diabética (Grupo 2) e 40 indivíduos saudáveis (Grupo 3). Os níveis hormonais de progesterona sérica, de proteína G sérica, estradiol, oxidante/antioxidante e hormônio liberado pela tireoide foram analisados e comparados. A análise post hoc foi realizada para comparar os subgrupos nos quais diferenças estatisticamente significativas foram encontradas. Resultados: Uma diferença significativa foi encontrada entre todos os grupos em termos de proteína G sérica, oxidante/antioxidante e níveis de estradiol (p<0.01), mas nenhuma diferença significativa foi encontrada em termos de hormônio liberado pela tireoide ou progesterona (p=0,496, p=0,220, respectivamente). Na análise post hoc dos grupos com diferenças estatisticamente significativas, outra diferença significativa foi encontrada entre todos os grupos para proteína G sérica e níveis oxidantes/antioxidantes (p<0,05). Os níveis de proteína G sérica e os níveis de oxidante foram positivamente correlacionados, enquanto os níveis de proteína G sérica e os níveis de antioxidantes foram negativamente correlacio­nados (r=0,622/p<0,01, r=0,453/p<0,01, r=0,460/p<0,01, respectivamente). A análise de regressão múltipla mos­trou que o aumento da proteína G sérica pode ajudar a prevenir a retinopatia diabética. Conclusões: Os níveis de proteína G sérica que eram mais altos no grupo de retinopatia diabética, aumentaram à medida que o equilíbrio oxidante/antioxidante mudou em favor do estresse oxidativo. Este parece ser um mecanismo de defesa para prevenir danos neuronais.

ABSTRACT

ABSTRACT Purpose: The regulatory effect of microRNA on diseases has been confirmed. This study aimed to evaluate the expression of microRNA-210-3p in age-related cataracts and assess the effect of abnormal miR-210-3p expressions on H2O2-induced SAR01/04 cells. Methods: Reverse-transcription quantitative polymerase chain reaction method was performed to assess the levels of miR-210-3p in aqueous humor samples. Receiver operating characteristic analysis was employed to assess the discrimination ability of miR-210-3p between patients with age-related cataracts and healthy people, and Pearson correlation analysis was used to identify the correlation between miR-210-3p and oxidative stress indices such as superoxide dismutase, glutathione peroxidase, malonaldehyde. Cell counting kit-8 assay and Transwell assay were used to estimate the biological function of H2O2-induced age-related cataract cell model. The levels of oxidative stress indices such as superoxide dismutase, glutathione peroxidase, and malonaldehyde were measured to evaluate the degree of oxidative stress damage in the age-related cataract cell model. The relationship between miR-210-3p and its target gene was verified by luciferase reporter gene analysis. Results: The miR-210-3p expression was elevated in the aqueous humor of patients with age-related cataracts. A high miR-210-3p expression showed a high diagnostic value for age-related cataracts and was significantly associated with the level of oxidative stress markers in patients with age-related cataracts. The inhibition of miR-210-3p can reverse oxidative stress stimulation and adverse effects on H2O2-induced cell function. Conclusions: The results suggested that miR-210-3p could promote cell viability, cell migration, and oxidative stress by targeting autophagy-related gene 7 in in vitro age-related cataract cell model.


RESUMO Objetivo: O efeito regulador do microRNA em doenças tem sido confirmado, e este artigo tentou avaliar a expressão do microRNA-210-3p na catarata relacionada à idade e avaliar o efeito da expressão anormal do miR-210-3p em células SAR01/04 induzidas por H2O2. Métodos: O método de transcrição reversa seguida de reação em cadeia da polimerase (RT-PCR) quantitativa foi realizado para avaliar os níveis de miR-210-3p em amostras de humor aquoso. Análise de características operacionais do receptor foi feita para avaliar a capacidade de discriminação do miR-210-3p entre pacientes com catarata relacionada à idade e pessoas saudáveis. A análise de correlação de Pearson identificou a correlação do miR-210-3p e índices de estresse oxidativo, como superóxido dismutase, glutationa peroxidase, malonaldeído. O ensaio de contagem de células kit-8 (cck-8) e o ensaio no sistema Transwell foram utilizados para estimar a função biológica do formato de células de catarata relacionada com a idade induzida por H2O2. Os níveis de índices de estresse oxidativo como superóxido dismutase, glutationa peroxidase e malonaldeído foram detectados para avaliar o grau de dano do estresse oxidativo em formato de células de catarata relacionada à idade. A relação entre miR-210-3p e seu gene alvo foi verificada por análise do gene repórter luciferase. Resultados: A expressão miR-210-3p foi elevada no humor aquoso de pacientes com catarata relacionada à idade. A expressão miR-210-3p altamente expressiva mostrou alto valor diagnóstico para catarata relacionada à idade e foi significativamente associado ao nível de marcadores de estresse oxidativo em pacientes com catarata relacionada à idade. A inibição de miR-210-3p pode reverter a estimulação do estresse oxidativo e os efeitos adversos da função celular induzida por H2O2. Conclusões: Esses dados sugeriram que a expressão miR-210-3p poderia promover a viabilidade celular, migração celular e estresse oxidativo ao direcionar genes ATG 7 relacionados à autofagia em modelo in vitro de células de catarata relacionadas à idade.

ABSTRACT

Abstract Objective: This study aimed to investigate the effects of systemic administration of P. eurycarpa Yalt. plant extract on alveolar bone loss and oxidative stress biomarkers in gingival tissue in a rat model of experimental periodontitis. Methodology: 32 male Wistar albino rats, weighing 200-250 g, were divided into four groups (n=8): Healthy control (HC), Experimental periodontitis control (EPC), Experimental periodontitis 400 mg/kg (EP400), Experimental periodontitis 800 mg/kg (EP800). Experimental periodontitis was induced using the ligating method. Distilled water was administered to the HC and EPC groups and the plant extract was administered to the EP400 and EP800 groups by oral gavage at doses of 400 mg/kg and 800 mg/kg, respectively. The rats were sacrificed on the 15th day. The values of glutathione peroxidase GSH-Px, malondialdehyde (MDA), superoxide dismustase (SOD), interleukin-1β (IL-1β), interleukin-10 (IL-10), total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI) in the gingival tissues were analyzed by ELISA tests. Alveolar bone loss was assessed using micro-CT images of the maxilla. Results: Although the IL-1β, TOS, OSI results of the healthy control group were lower than those of the other groups, the TAS values were higher (p<0.05). No significant difference was found in the biochemical parameters among the EPC, EP400, and EP800 groups (p>0.05). Alveolar bone loss was significantly reduced in the extract groups compared to the EPC group (p<0.001). Conclusion: Within the limitations of this study, it was observed that the systemic P. eurycarpa extract application reduced alveolar bone loss in a rat model of experimental periodontitis. Further studies are needed to elucidate the beneficial effects of P. eurycarpa.

ABSTRACT

Purpose: To investigate the protective effect of breviscapine on myocardial ischemia-reperfusion injury (MIRI) in diabetes rats. Methods: Forty rats were divided into control, diabetes, MIRI of diabetes, and treatment groups. The MIRI of diabetes model was established in the latter two groups. Then, the treatment group was treated with 100 mg/kg breviscapine by intraperitoneal injection for 14 consecutive days. Results: After treatment, compared with MIRI of diabetes group, in treatment group the serum fasting blood glucose, fasting insulin, homeostasis model assessment of insulin resistance, and glycosylated hemoglobin levels decreased, the serum total cholesterol, triacylglycerol, and low-density lipoprotein cholesterol levels decreased, the serum high-density lipoprotein cholesterol level increased, the heart rate decreased, the mean arterial pressure, left ventricular ejection fraction, and fractional shortening increased, the serum cardiac troponin I, and creatine kinase-MB levels decreased, the myocardial tumor necrosis factor α and interleukin-6 levels decreased, the myocardial superoxide dismutase level increased, and the myocardial malondialdehyde level decreased (all P < 0.05). Conclusions: For treating MIRI of diabetes in rats, the breviscapine can reduce the blood glucose and lipid levels, improve the cardiac function, reduce the myocardial injury, and decrease the inflammatory response and oxidative stress, thus exerting the alleviating effect.

ABSTRACT

Abstract Background: Trimethylamine N-oxide (TMAO), a gut microbiota metabolite, is associated with cardiovascular disease (CVD) development. TMAO can trigger an inflammatory response by inducing the nuclear factor-kappa B (NF-κB) signaling cascade and increasing the expression of pro-inflammatory cytokines, contributing to the worsening of CVD. This study aimed to evaluate the association between TMAO plasma levels and inflammation in patients with coronary artery disease (CAD). Methods: A cross-sectional study was carried out including 29 patients with CAD. Peripheral blood mononuclear cells (PBMC) were isolated from fasting blood samples, and NF-κB and vascular cell adhesion protein 1 (VCAM1) mRNA expression were estimated using real-time quantitative PCR. We determined TMAO plasma levels by LC-MS/MS and TNF-α by ELISA. Routine biochemical parameters were evaluated using an automatic biochemical analyzer. Correlations were estimated by Spearman or Pearson test. Statistical significance was set at the level of p < 0.05. Results: All patients presented TMAO levels within the normal range according to EUTox (normal range: 2.83 ± 1.53 mg/L; CAD patients: 0.2 [0.1 to 0.2] ng/μL). TMAO plasma levels were positively correlated with NF-κB mRNA expression (0.555; p = 0.002). Conclusion: TMAO plasma levels may be associated with NF-κB mRNA expression in patients with CAD and may contribute to the pathogenesis of this disease.

ABSTRACT

ABSTRACT Purpose: Pre-eclampsia (PE) is a pregnancy-related complication. Eucommia is effective in the treatment of hypertensive disorders in pregnancy, but the specific effects and possible mechanisms of Eucommia granules (EG) in PE remain unknown. The aim of this study was to investigate the effects and possible mechanisms of EG in PE rats. Methods: Pregnant Sprague Dawley rats were divided into five groups (n = 6): the control group, the model group, the low-dose group, the medium-dose group, and the high-dose group of EG. The PE model was established by subcutaneous injection of levonitroarginine methyl ester. Saline was given to the blank and model groups, and the Eucommia granules were given by gavage to the remaining groups. Blood pressure and urinary protein were detected. The body length and weight of the pups and the weight of the placenta were recorded. Superoxide dismutase (SOD) activity and levels of malondialdehyde (MDA), placental growth factor (PIGF), and soluble vascular endothelial growth factor receptor-1 (sFIt-1) were measured in the placenta. Pathological changes were observed by hematoxylin-eosin staining. Wnt/β-catenin pathway-related protein expression was detected using Western blot. Results: Compared with the model group, the PE rats treated with EG had lower blood pressure and urinary protein. The length and weight of the pups and placental weight were increased. Inflammation and necrosis in the placental tissue was improved. SOD level increased, MDA content and sFIt-1/PIGF ratio decreased, and Wnt/β-catenin pathway-related protein expression level increased. Moreover, the results of EG on PE rats increased with higher doses of EG. Conclusions: EG may activate the Wnt/β-catenin pathway and inhibit oxidative stress, inflammation, and vascular endothelial injury in PE rats, thereby improving the perinatal prognosis of preeclamptic rats. EG may inhibit oxidative stress, inflammation, and vascular endothelial injury through activation of the Wnt/β-catenin pathway in preeclampsia rats, thereby improving perinatal outcomes in PE rats.

ABSTRACT

ABSTRACT Purpose: XinJiaCongRongTuSiZiWan (XJCRTSZW) is a traditional Chinese medicine compound for invigorating the kidney, nourishing blood, and promoting blood circulation. This study aimed to explore the effect of XJCRTSZW on triptolide (TP)-induced oxidative stress injury. Methods: Adult female Sprague-Dawley rats and human ovarian granulosa cell lines were treated with TP and XJCRTSZW. Hematoxylin and eosin staining, enzyme-linked immunosorbent assay, flow cytometry, CCK-8, JC-1 staining, transmission electron microscopy, reverse transcription-quantitative polymerase chain reaction, and Western blotting were performed in this study. Results: XJCRTSZW treatment observably ameliorated the TP-induced pathological symptoms. Furthermore, XJCRTSZW treatment observably enhanced the TP-induced reduction of estradiol, anti-Mullerian hormone, progesterone, superoxide dismutase, ATP content, mitochondrial membrane potential, p62, and Hsp60 mRNA, and protein levels in vivo and in vitro (p < 0.05). However, TP-induced elevation of follicle stimulating hormone and luteinizing hormone concentrations, malondialdehyde levels, reactive oxygen species levels, apoptosis rate, mitophagy, and the mRNA and protein expressions of LC3-II/LC3-I, PTEN-induced kinase 1 (PINK1), and Parkin were decreased (p < 0.05). In addition, XJCRTSZW treatment markedly increased cell viability in vitro (p < 0.05). Conclusions: XJCRTSZW protects TP-induced rats from oxidative stress injury via the mitophagy-mediated PINK1/Parkin pathway.

ABSTRACT

ABSTRACT Purpose: Reflux esophagitis is a condition characterized by inflammation and irritation of the esophagus, resulting from the backflow of stomach acid and other gastric contents into the esophagus. Columbianadin is a coumarin derivative that exhibits anti-inflammatory and antioxidant effects. In this study, we tried to scrutinize the protective effect of Columbianadin against acute reflux esophagitis in rats. Methods: RAW 264.7 cells were utilized to assess cell viability and measure the production of inflammatory parameters. The rats received anesthesia, and reflux esophagitis was induced via ligation of pylorus and fore stomach and corpus junction. Rats received the oral administration of Columbianadin (25, 50 and 100 mg/kg) and omeprazole (20 mg/kg). The gastric secretion volume, acidity, and pH were measured. Additionally, the levels of oxidative stress parameters, cytokines, and inflammatory markers were determined. At the end of the study, mRNA expression was assessed. Results: Columbianadin remarkably suppressed the cell viability and production of tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), and prostaglandin (PGE2). Columbianadin treatment remarkably suppressed the secretion of gastric volume, total acidity and enhanced the pH level in the stomach. Columbianadin remarkably altered the level of hydrogen peroxidase, free iron, calcium, and plasma scavenging activity, sulfhydryl group; oxidative stress parameters like malonaldehyde, glutathione, superoxide dismutase, catalase, glutathione peroxidase; inflammatory cytokines viz., TNF-α, IL-6, IL-1β, IL-10, IL-17, and monocyte chemoattractant protein-1; inflammatory parameters including PGE2, iNOS, COX-2, and nuclear kappa B factor (NF-κB). Columbianadin remarkably (P < 0.001) suppressed the mRNA expression TNF-α, IL-6, IL-1β and plasminogen activator inhibitor-1. Conclusions: Columbianadin demonstrated a protective effect against acute reflux esophagitis via NF-κB pathway.

ABSTRACT

Abstract Background: This study examines the direct nephrotoxic effects of Daboia siamensis venom (RVV) and venom fractions in in vivo and isolated perfused kidneys (IPK) to understand the role of inflammation pathways and susceptibility to oxidative stress in venom or fraction-induced acute renal failure. Methods: We administered RVV and its venom fractions (PLA2, MP, LAAO, and PDE) to rabbits in vivo and in the IPK model. We measured oxidative stress biomarkers (SOD, CAT, GSH, and MDA) in kidney tissue, as well as inflammatory cytokines (TNF-α, IL-1β, IFN-γ, IL-4, IL-5, and IL-10), MDA and GSH levels in plasma and urine. We also calculated fractional excretion (FE) for pro-/anti-inflammatory cytokines and oxidative stress biomarkers, including the ratios of pro-/anti-inflammatory cytokines in urine after envenomation. Results: In both kidney models, significant increases in MDA, SOD, CAT, and GSH levels were observed in kidney tissues, along with elevated concentrations of MDA and GSH in plasma and urine after injecting RVV and venom fractions. Moreover, RVV injections led to progressive increases in FEMDA and decreases in FEGSH. The concentrations of IL-4, IL-5, IL-10, IFN-γ, and TNF-α in plasma increased in vivo, as well as in the urine of the IPK model, but not for IL-1β in both plasma and urine after RVV administrations. Urinary fractional excretion of TNF-α, IL-1β, IFN-γ, IL-4, IL-5, and IL-10 tended to decrease in vivo but showed elevated levels in the IPK model. A single RVV injection in vivo disrupted the balance of urinary cytokines, significantly reducing either the TNF-α/IL-10 ratio or the IFN-γ/IL-10 ratio. Conclusion: RVV induces renal tubular toxicity by increasing oxidative stress production and elevating inflammatory cytokines in urine. During the acute phase of acute kidney injury, the balance of urine cytokines shifts toward anti-inflammatory dominance within the first two hours post-RVV and venom fractions.

ABSTRACT

SUMMARY OBJECTIVE: We aimed to examine the effect of remission status on thiol-disulfide homeostasis in celiac patients and thus to indirectly determine the effect of oxidative stress and inflammation caused by non-compliance with the diet. METHODS: Between February 2019 and December 2021, 117 patients diagnosed with celiac disease were included in this prospective randomized and controlled study. In addition to routine tests of celiac patients, thiol and disulfide measurements were made from the blood both at the beginning of the study and at the end of the first year. RESULTS: While 52 of the patients (44.4%) were in remission, 65 patients (55.6%) were not. There was an evident increase in native thiol levels of the patients who were initially not in remission but went into at the end of the first year (347.4±46.7 μmol/L vs. 365.3±44.0 μmol/L; p=0.001). Mean plasma disulfide levels of patients with celiac going into remission became reduced in the first year from the level of 14.5±5.1 μmol/L down to 8.9±4.2 μmol/L (p<0.001). In celiac patients who entered remission, disulfide and anti-tissue transglutaminase immunoglobulin A levels decreased in a correlation (r=0.526; p<0.001). CONCLUSION: Not being in remission in celiac disease leads to increased oxidative stress, and thiol-disulfide homeostasis is an indirect indicator of this. Additionally, providing remission in celiac patients reduces oxidative stress.

ABSTRACT

ObjectiveTo investigate the effect of Tangbikang granules on oxidative stress of sciatic nerve in diabetic rats by regulating adenylate activated protein kinase/peroxisome proliferator-activated receptor γ coactivator-1α/mitochondrial Sirtuins 3 (AMPK/PGC-1α/SIRT3) signaling pathway. MethodThe spontaneous obesity type 2 diabetes model was established using ZDF rats. After modeling, they were randomly divided into high, medium, and low dose Tangbikang granule groups (2.5, 1.25, 0.625 g·kg-1·d-1) and lipoic acid group (0.026 8 g·kg-1·d-1), and the normal group was set up. The rats were administered continuously for 12 weeks after modeling. The blood glucose of rats was detected before intervention and at 4, 8, 12 weeks after intervention. At the 12th week, motor nerve conduction velocity (MNCV), sensory nerve conduction velocity (SNCV), nerve blood flow velocity, mechanical pain threshold, and thermal pain threshold were detected. The sciatic nerve was taken for hematoxylin-eosin (HE) staining to observe the tissue morphology. The ultrastructure of the sciatic nerve was observed by transmission electron microscope. The expression levels of superoxide dismutase (SOD), malondialdehyde (MDA), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) in sciatic nerve were determined by enzyme-related immunosorbent assay (ELISA). The mRNA expressions of AMPKα, AMPKβ, PGC-1α, and SIRT3 in sciatic nerve were determined by real-time polymerase chain reaction (Real-time PCR). ResultCompared with the normal group, fasting blood glucose in the model group was increased at each time point (P<0.01). The mechanical pain threshold was decreased (P<0.05), and the incubation time of the hot plate was extended (P<0.01). MNCV, SNCV, and nerve blood flow velocity decreased (P<0.05). The expression level of SOD was decreased (P<0.01). The expression levels of MDA, IL-1β, and TNF-α were increased (P<0.01). The mRNA expression levels of AMPKα, AMPKβ, PGC-1α, and SIRT3 were decreased (P<0.01). The structure of sciatic nerve fibers in the model group was loose, and the arrangement was disordered. The demyelination change was obvious. Compared with the model group, the fasting blood glucose of rats in the high dose Tangbikang granule group was decreased after the intervention of eight weeks and 12 weeks (P<0.01). The mechanical pain threshold increased (P<0.05). The incubation time of the hot plate was shortened (P<0.01). MNCV, SNCV, and Flux increased (P<0.05). The expression level of SOD was increased (P<0.01). The expression levels of MDA, IL-1β, and TNF-α were decreased (P<0.01). The mRNA expression levels of AMPKα, AMPKβ, PGC-1α, and SIRT3 were increased (P<0.01). The sciatic nerve fibers in the high-dose Tangbikang granule group were tighter and more neatly arranged, with only a few demyelinating changes. The high, medium, and low dose Tangbikang granule groups showed a significant dose-effect trend. ConclusionTangbikang granules may improve sciatic nerve function in diabetic rats by regulating AMPK/PGC-1α/SIRT3 signaling pathway partly to inhibit oxidative stress.

ABSTRACT

Endocrine disrupting chemicals (EDCs) are a class of chemical substances widely present in daily-life environment, and can enter human body through various pathways, posing a threat to reproductive development and health. Oxidative stress (OS) is one of the most important fundamental mechanisms underlying the reproductive toxicity of EDCs. Numerous studies have found that exposure to EDCs can increase the levels of reactive oxygen species (ROS) in human reproductive system and reduce the activity and quantity of multiple enzymatic antioxidants, leading to oxidative stress and inducing damage to the reproductive system at various levels such as DNA and cells. Many research results have shown that supplementing food-derived non-enzymatic antioxidants can reduce ROS levels and increase the activity of enzymatic antioxidants, thereby reduce OS levels, and further repair EDCs-induced reproductive damage. In addition, many food-derived antioxidants are important elements involved in reproductive physiological activities and have protective effects on reproductive health. This paper summarized the reproductive toxicity of EDCs, including damage to reproductive cells, interference with hormone action, and influence on reproductive-related epigenetic regulation, elaborated the relationship between OS and reproductive toxicity of EDCs, and further summarized the alleviating effects and related mechanisms of food-derived antioxidants such as vitamins, trace elements, and plant polyphenols and pigments against reproductive toxicity of EDCs, aiming to provide a theoretical and scientific basis for prevention and treatment against reproductive toxicity of EDCs.

ABSTRACT

Acute pancreatitis (AP) is a common clinical acute abdominal disease, which is characterized by acute onset, rapid development, severe disease, many complications, and high mortality rate. It can progress to severe AP (SAP) if not treated promptly in the early stage. The pathogenesis of AP is complex and involves multiple cellular and molecular levels. It is now clear that oxidative stress and reactive oxygen species (ROS) production are involved in the physiopathological process of AP, which is associated with a low quantity and activity of antioxidant enzymes in pancreatic cells. Nuclear factor E2-related factor 2 (Nrf2) serves as the ''golden key'' to maintain redox homeostasis in tissue cells and constitutes an important signaling pathway for antioxidant response and inflammation in vivo by collaborating with downstream antioxidant enzymes such as heme oxygenase-1 (HO-1). Traditional Chinese medicine has unique efficacy in treating diseases due to its multi-component, multi-target, multi-drug delivery, and multi-formulation characteristics. Based on the concept of synergy between traditional Chinese and Western medicine, traditional Chinese medicine is becoming a new craze in the treatment of AP. The level of oxidative stress and Nrf2/HO-1 signaling pathway in AP pancreatic tissue are in a dynamic change process, and the intervention of traditional Chinese medicine can clean ROS production, affect the inflammatory pathway, and reduce oxidative stress damage, so as to protect against pancreatic injury. This suggests that this pathway plays an important role in AP. This article reviews the recent literature on the regulation of the Nrf2/HO-1 signaling pathway by traditional Chinese medicine for AP and summarizes that the monomers of traditional Chinese medicine targeting this pathway are mainly heat-clearing and detoxifying, blood-activating and blood-stasis-removing, and Qi benefiting and middle warming, and the compounds of traditional Chinese medicine include Yinchenhao Decoction and QingYi Ⅱ, so as to provide a new direction for the prevention and treatment of AP and further drug development.
