Suppression of nitrosative stress and inflammation of the knee joint synovium in collagen type ii-induced rheumatoid arthritis by the inhibition of glycogen synthase kinase-3ß

Int. j. morphol; 40 (1), 2022
SUMMARY: Rheumatoid arthritis (RA), an inflammatory autoimmune disease that causes cartilage degradation and tissue destruction, can affect synovial joints such as the knee joint. The link between the nitrosative stress enzyme inducible nitric oxide synthase (iNOS) and the cytokine interleukin-1 (IL-1 ...

The beneficial effects of virgin olive oil against oxidative stress induced by hypercholesterolemia in rats

Acta sci., Health sci; 44 (), 2022
Cardiovascular disease(CVD) remains the major cause of mortality in the world, typically claiming a third of all deaths. The primary cause of CVD is atherosclerosis. Therefore, timely prevention and therapy of atherosclerosis are able to reduce the risk of the development of its clinical manif...

Effect of Prosopis ruscifolia on incretin and insulin secretion in alloxan-induced hyperglycemic rats

Vitae (Medellín); 29 (1), 2022
Background: Diabetes mellitus treatment is based on oral hypoglycemic agents or insulin. Medicinal plants constitute an option, and the leaves of Prosopis ruscifolia (Pr) were shown to be effective in reducing glycemia in hyperglycemic animals. Objective: In this paper, we report the effect of P. ru...

Endogenous and exogenous serotonin, but not sumatriptan, ameliorate seizures and neuroinflammation in the pentylenetetrazole-induced seizure model in rats

Arq. neuropsiquiatr; 80 (1), 2022
ABSTRACT Background: Epilepsy has neuropsychiatric comorbidities such as depression, bipolar disorder, and anxiety. Drugs that target epilepsy may also be useful for its neuropsychiatric comorbidities. Objective: To investigate the effects of serotonergic modulation on pro-inflammatory cytokines and th...

Effect of dietary plants on the production of immunoglobulins A in healthy Wistar rats

Introduction: some plants such as turmeric, cinnamon, and okra are known to have therapeutic functions such as antioxidant and anti-inflammatory activity. Furthermore, an immunomodulatory role has been observed in the production of antibodies, in particular immunoglobulin A (IgA), which mediates a variet...

Avaliação da influência da Coenzima Q10 sobre o processo de reparo periimplantar de implantes instalados em tíbias de ratos expostos ou não à nicotina

O propósito do presente estudo foi avaliar a influência da Coenzima Q10 (CoQ10) no reparo periimplantar em implantes instalados em tíbias de ratos modificados sistemicamente ou não pela nicotina. Oitenta ratos machos (Wistar), foram divididos em quatro grupos (n=20). No dia 0 os animais receberam um ...

Perinatal exposure to a high-fat diet alters proopiomelanocortin, neuropeptide Y and dopaminergic receptors gene expression and the food preference in offspring adult rats

Braz. j. biol; 82 (), 2022
Exposure to the hight-fat diet may alter the control of food intake promoting hyperphagia and obesity. The objective of this study was to investigate the effects of this diet on dopamine receptors (drd1 and drd2), proopiomelanocortin (pomc), neuropeptideY (npy) genes expression, and preference food in ad...

Incisional hernia repair in rats: description of the sublay technique under videomagnification system

Acta cir. bras; 37 (8), 2022
Purpose: To describe the technique of sublay correction of incisional hernia in Wistar rats under videomagnification system. Methods: Five male rats of the species Rattus norvegicus, of the Wistar lineage, with body weight between 250–350 g and 60 days old were used. Incisional hernia was inducted in ...

Microsurgical arterial anastomosis in young and adult rats: an evolutive and comparative study

Acta cir. bras; 37 (6), 2022
Purpose: To evaluate the caliber of an arterial micro-anastomosis in the young growing animal using a continuous suture technique. Additionally, late morphological changes and blood flows distal to the anastomosis were evaluated. Methods: Seventy-four Wistar rats were submitted to laparotomy to access t...

Treatment of experimentally induced partial-thickness burns in rats with different silver-impregnated dressings

Acta cir. bras; 37 (8), 2022
Purpose: To evaluate the morphometric, macroscopic and microscopic aspects of experimentally induced partial-thickness burns in rats treated with different silver-based dressings. Methods: Wistar rats were used, divided into six treatments: saline (NaCl 0.9%); silver sulfadiazine 1%; Silvercel; Mepilex ...
