Invisible enemies: evaluating human health threats of mosquito repellents through animal studies.

Mosquito-borne diseases continue to pose significant threats to human populations, especially in developing and underdeveloped regions, where access to effective preventive measures remains limited. Mosquito repellents represent a cornerstone in the arsenal against these diseases, providing a barrier against mosquito bites. Mosquito repellents come in various formulations, including topical ointments and commercial vaporizers, with varying compositions.

Mechanistic interplay of dual environmental stressors: Bisphenol-A and cadmium-induced ovarian follicular damage and hepatocyte dysfunction in vivo.

This study investigates the individual and combined toxic effects of Bisphenol A (BPA) and Cadmium (Cd) in zebrafish, recognizing the complex mixture of pollutants organisms encounter in their natural environment. Examining developmental, neurobehavioral, reproductive, and physiological aspects, the study reveals significant adverse effects, particularly in combined exposures. Zebrafish embryos exposed to BPA + Cd exhibit synergistically increased mortality, delayed hatching, and morphological abnormalities, emphasizing the heightened toxicity of the combination.

Osteoporosis in polycystic ovary syndrome (PCOS) and involved mechanisms.

Polycystic Ovary Syndrome (PCOS) and osteoporosis, though seemingly unrelated, exhibit intricate connections influenced by genetic and epigenetic factors. PCOS, characterized by elevated androgen levels, insulin resistance, and increased body weight, has historically been considered protective against bone fragility disorders. However, emerging research suggests that chronic inflammation, prevalent in PCOS, can adversely affect bone health.
