- 围产期流行病学 围产期流行病学
背景情况:
- 过早分娩仍然是婴儿死亡的一个重要原因,在许多情况下,病因不明.
- 环境暴露,包括内分泌干扰化学物质,如酸盐,被怀疑是导致早产的因素.
- 酸盐是广泛使用的增塑剂,导致人类无处不在的暴露,但它们对妊娠时间的影响报告不一致.
研究的目的:

Teratogenicity
2.8K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Pathophysiology of Diabetes
1.2K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
