We report evidence of a displacive phase transformation from retained austenite to martensite during preparation of quenched and partitioned steel micro-pillars by using a focused ion beam (FIB) technique. The BCC phase produced by the FIB damage was identified as martensite. The invariant-plane strain surface relief associated with the martensitic transformation was observed in the retained austenite phase immediately after a FIB scan of the surface with the Ga ion beam.

Hydrogen is introduced in PHS during the hot press forming (HPF) process, by an atmospheric corrosion process. In this study, the hydrogen embrittlement behavior of uncoated, aluminized, and galvanized PHSs was investigated.

Thus, protection of hepatocytes against alcohol-induced death is considered to be a critical approach to prevent development of liver disease. Substance P (SP) is capable of promoting cell proliferation and blocking cell death under diverse stresses, leading to beneficial effects in severe diseases, and is therefore likely to have a therapeutic application in hepatic injury.

The strain hardening behavior during tensile deformation of a lath martensitic press hardening steel was described using a dislocation density-based constitutive model.

Thus, regulation of inflammation is regarded as the ultimate therapy for intestinal disease. Substance-P (SP) is known to mediate proliferation, migration, and cellular senescence in a variety of cells.

Background: Acetyl-L-carnitine (ALC) has demonstrated neuroprotective effects in several experiments and is widely prescribed to reduce cognitive impairment in Alzheimer's disease patients or manage neuropathic symptoms in diabetic patients.
Objectives: This study was designed to assess the pharmacokinetic (PK) bioequivalence between a new generic (test) formulation of ALC hydrochloride 590 mg and a branded (reference) formulation of ALC hydrochloride 590 mg in healthy Korean male volunteers.
Methods: This was a randomizedsequence, single-dose, two-way crossover study.
Purpose: The purpose of this study was to investigate the effects of aquatic exercise and CES treatment on the cognitive function by using K-WAB and BDNF, IGF-1, and VEGF of persons with intellectual disabilities.
Methods: All subjects were 15 male with intellectual disabilities who were participating in the aquatic training program and CES treatment during 12 weeks at rehabilitation center. The subjects were divided into control group, exercise group, and exercise+CES group.
An exopolysaccharide-producing Gram negative bacterium was isolated and determined to be a Sphingomonas sp. (CS101). A sugar composition analysis of an exopolysaccharide indicated that the Sphingomonas sp.
