We introduce an application of thermionic emission in a PMT photocathode. Because of the nonlinear dependence of thermionic emission on absorbed laser power, a conventional PMT is found to produce a virtual pinhole effect that rejects unfocused light at least as strongly as a physical pinhole. This virtual pinhole effect is exploited in a scanning transmission confocal microscope equipped with ...

BACKGROUND Paratonia, a form of hypertonia, is associated with loss of mobility and with the development of contractures especially in the late stages of the dementia. Passive movement therapy (PMT) currently is the main physiotherapeutic intervention. General doubt about the beneficial effects of this widely used therapy necessitates a randomised clinical trial (RCT) to study the efficacy of P...

Protein O-mannosyltransferases (PMTs) catalyze the initial reaction of protein O-mannosylation by transferring the first mannose unit onto serine and threonine residues of a nascent polypeptide being synthesized in the endoplasmic reticulum (ER). The PMTs are well conserved in eukaryotic organisms, and in vivo defects of these enzymes result in cell death in yeast and congenital diseases in hum...

d-Fenfluramine (d-Fen) has been demonstrated to alter body temperature (BT), decrease 5-hydroxytryptamine (5-HT) and decrease 5-HT plasma membrane transporters (PMT) in rats. Therefore, experiments were designed to test whether a correlation existed between elevated BT and brain 5-HT depletions. It was hypothesized that d-Fen would induce hyperthermia if the environmental temperature was elevat...

Xanthomonas oryzae pv.oryzae (Xoo) causes the serious bacterial blight disease of rice. Xoo secretes a repertoire of plant cell wall degrading enzymes (CWDEs) like cellulases, xylanases, esterases etc., which act on various components of the rice cell wall. The major cellulases and xylanases secreted by Xoo have been identified and their role in virulence has been determined. In this study, we ...

The 146-kDa Pasteurella multocida toxin (PMT) is the main virulence factor to induce P. multocida-associated progressive atrophic rhinitis in various animals. PMT leads to a destruction of nasal turbinate bones implicating an effect of the toxin on osteoblasts and/or osteoclasts. The toxin induces constitutive activation of Gα proteins of the G(q/11)-, G₁₂/₁₃- and G(i)-family by deamidating an ...

Multilevel determinants of sedentary behavior (SB), including constructs couched within evidence-based psychological frameworks, can contribute to more efficacious interventions designed to decrease sitting time. This study aimed to: (1) examine the factor structure and composition of sedentaryderived protection motivation theory (PMT) constructs and (2) determine the utility of these construct...

Protein O mannosylation is initiated in the endoplasmic reticulum by protein O-mannosyltransferases (Pmt proteins) and plays an important role in the secretion, localization, and function of many proteins, as well as in cell wall integrity and morphogenesis in fungi. Three Pmt proteins, each belonging to one of the three respective Pmt subfamilies, are encoded in the genome of the human fungal ...

Detailed Monte-Carlo simulations were used to evaluate the performance of a liquid neon scintillation detector for dark matter and low-energy solar neutrino interactions. A maximum-likelihood event vertex fitter including PMT time information was developed, which significantly improves position resolution over spatial-only algorithms, and substantially decreases the required detector size and a...
