Published: May 2018

Preeclampsia is a persistent hypertensive gestational disease characterized by high blood pressure and proteinuria, which presents from the second trimester of pregnancy. At the cellular level, preeclampsia has largely been associated with the release of free radicals by the placenta. Placenta-borne oxidative and nitrosative stresses are even sometimes considered as the major molecular determinants of the maternal disease. In this review, we present the recent literature evaluating free radical production in both normal and pathological placentas (including preeclampsia and other major pregnancy diseases), in humans and animal models. We then assess the putative effects of these free radicals on the placenta and maternal endothelium. This analysis was conducted with regard to recent papers and possible therapeutic avenues.

This study aims to reveal the potential molecular mechanisms of modified Gegen Qinlian decoction (MGQD) in relieving ulcerative colitis (UC). C57BL/6J mice were used to establish experimental colitis via dextran sodium sulfate (DSS). Body weight, disease activity index (DAI), spleen weight, colon length, and histopathologic features were measured to evaluate the therapeutic effects of MGQD on mice with UC.

Oxidative stress (OS) is established as a key factor in the etiology of both male and female infertility, arising from an imbalance between reactive oxygen species (ROS) production and the endogenous antioxidant (AOX) defenses. In men, OS adversely affects sperm function by inducing DNA damage, reducing motility, significantly impairing sperm vitality through plasma membrane peroxidation and loss of membrane integrity, and ultimately compromising overall sperm quality. In women, OS is implicated in various reproductive disorders, including polycystic ovary syndrome, endometriosis, and premature ovarian failure, leading to diminished oocyte quality, disrupted folliculogenesis, and poorer reproductive outcomes.

Here, a high molecular weight polysaccharide preparation from Ophiocordyceps gracilis was utilized as a stabilizer and dispersant to create nanocomposites based on selenium nanoparticles (GSP-1a-SeNPs). The NPs showed the highest stability at a selenium/polysaccharide mass ratio of 1:1, with no significant change after 28 days of storage at 4 °C. The NPs exhibited a symmetrical spheroid structure with an average diameter of 85.

Xanthine oxidase (XO) and lactoperoxidase (LPO) are highly abundant enzymes in milk. Their substrates, xanthine and thiocyanate, are found in elevated amounts in infant saliva, leading to a proposed interaction between milk and saliva referred to as the XO-LPO system. This system is suggested to generate reactive oxygen and nitrogen species with potential antibacterial effects.
