Obesity influences the development of bisphosphonate-induced osteonecrosis in Wistar rats.

Medication-related osteonecrosis of the jaw (MRONJ) is characterized by bone exposure for more than eight weeks in patients who have used or been treated with antiresorptive or antiangiogenic drugs, without a history of radiation therapy or metastatic diseases in the jaws. Obesity is associated with changes in periodontal tissues and oral microbiota that are linked to bone alterations. This study aimed to analyze the influence of obesity on the development of bisphosphonate-induced osteonecrosis.

Intermittent fasting associated with aerobic exercise improves oxidative parameters and causes muscle damage without compromising the performance of Wistar rats.

Objectives: The aim of this study was to` investigate the effects of intermittent fasting (IF) and the possible association with aerobic exercise on performance, oxidative, biochemical, and somatic parameters of Wistar rats.

Methods: Forty rats were randomized into the following groups: sedentary (SC) and trained (TC) controls, sedentary intermittent fasting (SIF), and trained intermittent fasting (TIF). The rats were subjected to IF for 15 h every day and aerobic exercise lasting 30 min, five times a week, at a speed of 15 m/min for 4 wk.

Maternal high-fat diet alters the neurobehavioral, biochemical and inflammatory parameters of their adult female rat offspring.

Background: Lipid metabolism dysregulations have been associated with depressive and anxious behaviors which can affect pregnant and lactating individuals, with indications that such changes extend to the offspring. Therefore, the aim of this study was to evaluate the effect of a maternal high-fat diet on the neurobehavioral, biochemical and inflammatory parameters of their adult female offspring.

Methods: Wistar rats ± 90 days old were mated.

Malicia honey (Mimosa quadrivalvis L.) produced by the jandaíra bee (Melipona subnitida D.) improves depressive-like behaviour, somatic, biochemical and inflammatory parameters of obese rats.

Malícia honey produced by the jandaíra bee has hypoglycaemic and hypolipidemic effects and antioxidant activity in vitro and in vivo, which makes it potential adjuvant treatment for obesity. This study aimed to evaluate the effects of malícia honey on somatic and biochemical parameters, depressive-like behaviour and anti-inflammatory activity in obese rats. A total of 40 adult male Wistar rats were initially randomized into a healthy group (HG, n = 20) that consumed a control diet, and an obese group (OG, n = 20) which consumed a cafeteria diet for eight weeks.
