Tsa1 is the dominant peroxide scavenger and a source of HO-dependent GSSG production in yeast.

Hydrogen peroxide (HO) is an important biological molecule, functioning both as a second messenger in cell signaling and, especially at higher concentrations, as a cause of cell damage. Cells harbor multiple enzymes that have peroxide reducing activity in vitro. However, the contribution of each of these enzymes towards peroxide scavenging in vivo is less clear.

Watching Televised Counter-Stereotypes Alone or with Mom: Studying the Effects on Preadolescents' Gender Attitudes and Beliefs.

Despite the dominant presence of traditional gender portrayals on television, there is a growing effort to incorporate more diverse gender representations, including in youth television series. The impact of such counter-stereotypical portrayals on preadolescents' gender attitudes and beliefs remains largely unexplored. This mixed-design experimental study among 75 mother-child dyads ( = 10.

Brain-derived neuerotrophic factor and related mechanisms that mediate and influence progesterone-induced neuroprotection.

Historically, progesterone has been studied significantly within the context of reproductive biology. However, there is now an abundance of evidence for its role in regions of the central nervous system (CNS) associated with such non-reproductive functions that include cognition and affect. Here, we describe mechanisms of progesterone action that support its brain-protective effects, and focus particularly on the role of neurotrophins (such as brain-derived neurotrophic factor, BDNF), the receptors that are critical for their regulation, and the role of certain microRNA in influencing the brain-protective effects of progesterone.
