The mechanisms that drive placental dysfunction in pregnancies complicated by hypoxia and fetal growth restriction remain poorly understood. Changes to mitochondrial respiration contribute to cellular dysfunction in conditions of hypoxia and have been implicated in the pathoaetiology of pregnancy complications, such as pre-eclampsia. We used bespoke isobaric hypoxic chambers and a combination of functional, molecular and imaging techniques to study cellular metabolism and mitochondrial dynamics in sheep undergoing hypoxic pregnancy.

Gansu University of Chinese Medicine, Lanzhou, Gansu Province, China.
Background: Previous research has demonstrated that exposure to individual heavy metals elevates the incidence rate of congenital heart defects (CHDs). However, there is a paucity of data concerning the relationship between combined exposure to multiple heavy metals and the occurrence of CHDs. This study seeks to investigate the association between combined heavy metal exposure in pregnant women and the incidence of CHDs in their offspring in Lanzhou, China.

Preterm birth remains a leading cause of neurodevelopmental disability in offspring, prompting various preventive measures. However, controversies persist surrounding these approaches, particularly regarding beta-mimetic drugs. In Japan, it remains a concerning reality that ritodrine infusion continues to be used for long-term tocolysis in preterm labor, despite the warning issued by the US Food and Drug Administration.

Tartrazine finds widespread application in the realms of alimentation, pharmaceuticals, cosmetic formulations, and textile manufacturing. Tartrazine has a negative effect on human health such as hyperactivity, allergies and asthma in children. Substances such as tartrazine might effect the embryo in a kind of aspects, containing physical or mental disorders, and a decrease in the child's intellectual memory.
