Recent evidence indicates that the ephrin receptors and ephrin ligands (Eph/ephrin) expression modulate axonal reorganization and synaptic plasticity in stroke recovery. To investigate the effect of task-specific training (TST) on Eph/ephrin expression in the corticospinal tract (CST) after stroke, we compared Eph/ephrin expression in the peri-infarct cortex, pyramid, and spinal cord of a photo...

Transition state theory (TST) 1 is the most widely used theory for calculating rates of bimolecular eactions occurring in the gas phase and in condensed phases. TST is also incorporated into the widely used RRKM theory for unimolecular reactions. The popularity of TST is largely due to its simplicity and its usefulness for correlating trends in reaction rates in terms of easily interpreted quan...

The recently proposed threat simulation theory (TST) states that dreaming about threatening events has a biological function. In the past few years, the TST has led to several dream content analysis studies that empirically test the theory. The predictions of the TST have been investigated mainly with a new content analysis system, the Dream Threat Scale (DTS), a method developed for identifyin...

BACKGROUND Not all health care workers (HCWs) are at the same risk for tuberculin skin test (TST) conversion, indicating latent tuberculosis (TB) infection. OBJECTIVE To identify risk factors for TST conversion among HCWs. METHODS A retrospective cohort study conducted at a tertiary university medical centre included every HCW who had had a negative two-step TST at work entry and at least o...

Background Understanding whether the preceding low lipid profile leads to active tuberculosis (TB) or active TB leads to low lipid profile is crucial. Methods Lipid profile concentrations were determined from 159 study participants composed of 93 active TB patients [44 HIV coinfected (HIV+TB+) and 49 HIV negative (HIV-TB+)], 41 tuberculin skin test (TST) positive cases [17 HIV coinfected (HIV...

Progressive multifocal leukoencephalopathy results from an opportunistic infection of myelin-producing oligodendrocytes by the glia-specific human papovavirus JC. In this report, evidence is presented that the glial transcription factor Tst-1, a member of the POU-domain family, stimulates transcription of both early and late viral genes. Stimulation was dependent on site-specific binding of Tst...

BACKGROUND Military personnel are at risk for acquiring Mycobacterium tuberculosis infection because of activities in close quarters and in regions with a high prevalence of tuberculosis (TB). Accurate tests are needed to avoid unnecessary treatment because of false-positive results and to avoid TB because of false-negative results and failure to diagnose and treat M. tuberculosis infection. We...

The tuberculin skin test (TST) was compared with QuantiFERON-TB Gold in-tube (QFT-GIT) test for the diagnosis of tuberculosis in non-Mycobacterium bovis BCG-vaccinated military personnel. Among subjects positive by TST, 44.4% of recruits were positive by QFT-GIT compared with 11.5% subjects tested after missions abroad, suggesting that most TST conversions in the latter group were caused by non...

Abstract This paper compares the degradation of sintered silver (s-Ag) die attach between thermal shocked test (TST) and mechanical cycling to correctly understand mechanism s-Ag failure in power module products during practical operation. A bar-shaped specimen is subjected two types four-point bending tests: centered (CBT) for moment application shifted (SBT) shear force application. crack pat...

BACKGROUND Despite sustained exposure to a person with pulmonary tuberculosis (TB), some M. tuberculosis (Mtb) exposed individuals maintain a negative tuberculin skin test (TST). Our objective was to characterize these persistently negative TST (PTST-) individuals and compare them to TST converters (TSTC) and individuals who are TST positive at study enrollment. METHODS During a TB household ...
