The Relationship

An analytical and experimental study was conducted to investigate the elastic and failure behavior of composite laminated pipe under torsion. The analytical model was developed based on the mechanics of composite materials and the maximum strain failure criterion. Five composite pipe samples were tested on a specially designed pipe torsional tester. A finite element analysis was also performed to be compared with the analytical and experimental results. The relationship between applied torque and shear strain and between torque and torsional angles was obtained by all three methods. The effects of fiber angle and its deviation were also studied.

Anaerobic Test

The relationship between vibriocin production by streptomycin-sensitive (SMs) Vibrio comma and a specific redox potential is described. Streptomycin-resistant (SMr) mutants are shown to be predominantly sensitive to vibriocin and thus serve as indicator strains. Vibriocin sensitivity can be demonstrated under aerobic but not anaerobic test conditions. A discussion is given, implicating bacteriocins as a factor contributing to the "Welsch phenomenon" wherein the growth of a mixed population of SMs and SMr bacteria in broth results in a steady decrease of the SMr mutants to the level normally present in a sensitive culture.

Definite Limit

Homocysteine (HCY), a physiological amino acid formed when proteins break down, leads to a pathological condition called hyperhomocysteinemia (HHCY), when it is over a definite limit. It is well known that an increase in HCY levels in blood, can contribute to arterial damage and several cardiovascular disease, but the knowledge about the relationship between HCY and brain disorders is very poor. Recent studies demonstrated that an alteration in HCY metabolism or a deficiency in folate or vitamin B12 can cause altered methylation and/or redox potentials, that leads to a modification on calcium influx in cells, or into an accumulation in amyloid and/or tau protein involving a cascade of events that culminate in apoptosis, and, in the worst conditions, neuronal death. The present review will thus summarize how much is known about the possible role of HHCY in neurodegenerative disease.
