Chronic cannabinoid exposure during adolescence in male rats induces chronic cognitive and emotional impairments. However, the impact of this form of exposure on offspring vulnerability to stress is unknown. The aim of this study was to evaluate the behavioural and epigenetic effects of stress in the offspring of male rats whose fathers were exposed to cannabinoids during adolescence. Male adolescent offspring of Win55,212‐2 (1.2 mg/kg) treated rats were exposed during one week to variable stressors and subjected to behavioural tests of anxiety and episodic‐like memory, followed by an assessment of global DNA methylation and expression of DNA methyltransferases enzymes DNMT1 and DNMT3a mRNA in the prefrontal cortex. Stress exposure induced a significant anxiogenic‐like effect but did not affect the episodic‐like memory in the offspring of Win55,212‐2 exposed fathers in comparison to the offspring of non‐exposed fathers. These behavioural changes were subsequent to a significant increase in global DNA methylation and DNMT1 and DNMTa3 transcription in the prefrontal cortex. These data suggest that the deleterious effect of chronic exposure to cannabinoids during adolescence are not limited to the exposed individuals but may increase the vulnerability to stress‐induced anxiety in the offspring and alter their epigenetic programming.

Background: University life is a crucial period when dietary habits and lifestyle behaviours are formed and may have long-lasting effects on the development of obesity and related chronic diseases. Aim: To investigate the association of overweight/obesity with dietary habits, physical activity, screen time and sleep duration among university students. Methods: A total of 438 students aged 18–26 years were recruited from Mohammed V University in Rabat, Morocco. Anthropometric measurements were assessed using standardized equipment. Data regarding dietary habits, physical and sedentary activities were collected via a self-administered questionnaire. Results: The prevalence of overweight and obesity was 14.8% and 1.6%, respectively. Students who reported frequent consumption (>3 times/week) of fast food, fried potatoes and sugary drinks were more likely to be overweight/obese than peers who did not. Similarly, odds of being overweight/obese were slightly higher among females who reported non-daily intake of fruits and milk or dairy products and among males who ate vegetables less frequently (<7 times/week). Approximately 26% of students were physically inactive, with a higher proportion of females (35.8%) than males (10.7%). Both short and long sleep durations were associated with an increased risk of overweight/obesity in males. In contrast, physical inactivity and increased screen time were associated with a slightly reduced risk of overweight/obesity, particularly in females. Conclusions: Overall, unhealthy dietary habits were associated with an increased risk of overweight/obesity. A similar trend was also observed between abnormal sleep duration and overweight/obesity in males. Interventions to promote healthy dietary and lifestyle habits and prevent overweight/obesity in this population are needed.

Objective: This study was undertaken to justify and validate a very frequent traditional use of a very well-known and widely used plant by a large part of the Moroccan population. It's about Corrigiola telephiifolia, and the activity in question is the diuretic activity. Methods: The aqueous ethanol root extract of corrigiola telephiifolia (200 mg/kg, 400 mg/kg, and 700 mg/kg) was orally administered to rats. The urinary excretion rate and pH, and electrolyte excretion were measured in the urine of saline-loaded rats. Negative control group received only an equivalent volume of distilled water, while the positive control groups received the diuretic drugs hydrochlorothiazide at dose 10 mg/kg. Results: The results showed that hydrochlorothiazide induced significant diuresis and electrolytes excretion at 1, 6 and 24 h after the treatment. Both the higher doses of the extract produced a significant increase in urine volume than the control from the first hour until the end of observation. However, the lowest dose increased significantly only at 24 h after the treatment. With regard to the electrolyte excretion, the tested doses of CTRE which have shown a significant increase in Na + , K + and Clexcretion in comparison to normal control rats, are 400 and 700 mg/kg bw. Conclusion: These findings collectively indicate that the extracts of C. telephiifolia have a potential to induce diuresis markedly, and providing evidence, for its traditional use.
