Neuroprotective effects of selenium against lithium-induced cerebellar toxicity in rats: The role of apoptosis, gliosis, and aging markers.

Background: Prolonged lithium therapy in psychiatric disorders may be complicated by multi-organ dysfunction, particularly in the nervous system. Toxicity to the cerebellum is one of these, which, while uncommon, inevitably emerges negatively and permanently. Selenium is a trace element regarded as one of the critical antioxidants.

Selenium modulates bisphenol A-induced intestinal apoptosis, oxidative stress and autophagy in rats: A biochemical, histological and immunohistochemical study.

Bisphenol A (BPA) is a hazardous endocrine disruptor released into the environment during the production of certain plastics used for covering of food and beverage cans. In this work, we examined the protective benefits of selenium (Se) against intestinal damage induced by BPA in male rats. Rats were distributed randomly into four groups.

Rarity of monodominance in hyperdiverse Amazonian forests.

Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" forests are known from all of the main tropical regions.
