Assessment of reduction in stimulus generalization of ethanol-seeking during recovery: A rapid procedure.

Previously, we developed a procedure which showed that longer histories of reinforced alternative behavior decrease the risk of relapse caused by a range of stimuli which had previously occasioned drinking. The decrease in relapse risk was likely due to a decrease in attention to the stimuli over the course of repeated engagement in the alternative behavior. However, this previous procedure was time consuming and did not mirror the procedure we used to observe changes in relapse risk.

Judges' attitudes and experiences related to a trauma-informed approach: An exploratory study.

Objective: Understanding judges' views is crucial to the successful adoption of a trauma-informed (TI) approach in the U.S. court system, yet little is known on this topic.

Structural Evolution of Photoexcited Methylcobalamin toward a CarH-like Metastable State: Evidence from Time-Resolved X-ray Absorption and X-ray Emission.

CarH is a protein photoreceptor that uses a form of B, adenosylcobalamin (AdoCbl), to sense light via formation of a metastable excited state. Aside from AdoCbl bound to CarH, methylcobalamin (MeCbl) is the only other example─to date─of photoexcited cobalamins forming metastable excited states with lifetimes of nanoseconds or longer. The UV-visible spectra of the excited states of MeCbl and AdoCbl bound to CarH are similar.

ALDH2 polymorphism and myocardial infarction: From alcohol metabolism to redox regulation.

Acute myocardial infarction (AMI) remains a leading cause of death worldwide. Increased formation of reactive oxygen species (ROS) during the early reperfusion phase is thought to trigger lipid peroxidation and disrupt redox homeostasis, leading to myocardial injury. Whilst the mitochondrial enzyme aldehyde dehydrogenase 2 (ALDH2) is chiefly recognised for its central role in ethanol metabolism, substantial experimental evidence suggests an additional cardioprotective role for ALDH2 independent of alcohol intake, which mitigates myocardial injury by detoxifying breakdown products of lipid peroxidation including the reactive aldehydes, malondialdehyde (MDA) and 4-hydroxynonenal (4-HNE).
