Agmatine Signaling: Odds and Threads

P62: Agmatine Protects Against Intracerebroventricular Streptozotocin-Induced Water Maze Memory Deficit, Hippocampal ApoptosisandAkt/GSK3β Signaling Disruption

Intracerebroventricular stereptozotocin (STZ) treatment has been described as a suitable model for sporadic Alzheimer’s disease (sAD). Centrally administered STZ decreases insulin and insulin receptors in the brain and interrupts PI3/Akt signaling pathway and GSK-3β. Additionally it raises Bax/Bcl-2 ratio and prompts hippocampal apoptosis. Agmatine, a polyamine derived from L-arginin...

Making sense of odds and odds ratios.

Odds and odds ratios are hard for many clinicians to understand. Odds are the probability of an event occurring divided by the probability of the event not occurring. An odds ratio is the odds of the event in one group, for example, those exposed to a drug, divided by the odds in another group not exposed. Odds ratios always exaggerate the true relative risk to some degree. When the probability...

Agmatine Ameliorates High Glucose-Induced Neuronal Cell Senescence by Regulating the p21 and p53 Signaling

Neuronal senescence caused by diabetic neuropathy is considered a common complication of diabetes mellitus. Neuronal senescence leads to the secretion of pro-inflammatory cytokines, the production of reactive oxygen species, and the alteration of cellular homeostasis. Agmatine, which is biosynthesized by arginine decarboxylation, has been reported in previous in vitro to exert a protective effe...

A Crossing with Java Threads and POSIX Threads

The primitives for Java threads and POSIX threads are compared by means of a simulation of cars at a crossing. These cars have to be synchronized in such a way that at every moment only cars in one direction proceed. The initial solution is based on compound await statements. This solution is subsequently implemented with Java threads and POSIX threads. These two thread formalisms differ: POSIX...
