Background Vitamin D regulates cell growth and differentiation, encourages pro-apoptotic effect, stimulates antiangiogenic effect, and affects both innate and adaptive immunity. However, serum vitamin D level could differ between countries according to geographic, genetic, and dietary factors. Aim of the work Cosidering that most studies of relations between vitamin D level and breast cancer were conducted outside Africa and c...

The study aimed to assess the mitigation of negative impacts of heat stress (HS) by the willow bark ( Salix mucronata Thunb.) powder (SWBP) or betaine (BET) as natural antioxidants on semen quality, blood biochemicals, and oxidative status in rabbit bucks. Under control conditions, forty mature NZW adult males were distributed into five groups of eight replicates. The 1st group fed the basal diet without any additives (control...

Wheat is one of the most important cereal crops and an important source of food for billions of people worldwide. However, drought stress can pose a real threat to its productivity and lead to significant yield losses, especially in Egypt. The rhizospheric microbiome of wheat can play an important role in drought stress and help wheat to respond to this abiotic stress. Understanding this microbiome is therefore also important...

Aging represents a complex biological process associated with decline in skeletal muscle functions. Aging impairs satellite cells that serve as muscle progenitor cells. Probiotic supplementation may have many beneficial effects via various mechanisms. We examined the possible effects of probiotics in stimulating the proliferation of myogenic stellate cells in aging rats . Twenty-four male albino Sprague–Dawley rats were classi...
