January 1983 (T/E) c, b, AND T LIFETIME MEASUREMENTS IN e+eINTERACTIONS* . John A. Jaros Stanford Linear Accelerator Center INTRODUCTION Measurements of the lifetimes of weakly decaying particles let us infer the strength of the interaction responsible for their decay. Two features of these interactions have emerged from studies of the lighter quarks and leptons. First, the interactions have un...

Despite the availability of effective anti-rabies vaccine, rabies keeps affecting people in developing countries such as Côte d'Ivoire. The low compliance with Post Exposure Prophylaxis (PEP) partially explains this situation. This study was aiming at studying the reasons to abandon PEP. This descriptive and cross-sectional study has taken place at the anti-rabies Center of Abidjan from October...

Phosphoenolpyruvate phosphomutase (PEP mutase) from Tetrahymena pyriformis catalyzes the rearrangement of phosphoenolpyruvate (PEP) to phosphonopyruvate (P-pyr). A spectrophotometric P-pyr assay consisting of the coupled actions of P-pyr decarboxylase, phosphonoacetaldehyde hydrolase, and alcohol dehydrogenase was devised to monitor mutase catalysis. The reaction constants determined for PEP mu...

BACKGROUND Acute pancreatitis is the most common complication of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP). Several clinical trials used glyceryl trinitrate (GTN) to prevent the incidence of post-ERCP pancreatitis (PEP). However, the results were still controversial. OBJECTIVE To conduct a meta-analysis of published, full-length, randomized controlled tr...

In the current study, the role of pre-ejection period (PEP) and respiratory sinus arrhythmia (RSA) was studied in the association between prior adversities and antisocial behavior in adolescence. PEP and RSA task reactivity and recovery to a public speaking task were assessed in adolescents from a longitudinal population-based study (N=624, Mage=16.14 years, 49.2% boys). Perinatal adversities w...

To date there are no published studies on the effectiveness of HIV post-exposure prophylaxis (PEP) after sexual exposure. However, as emergency physicians we are faced with the dilemma of assessing the risk of HIV transmission and providing appropriate care for patients who present to us after sexual assault. Current practice in UK emergency departments and genitourinary clinics varies from tru...

PEP-19 is a small protein that increases the rates of Ca2+ binding to the C-domain of calmodulin (CaM) by an unknown mechanism. Although an IQ motif promotes binding to CaM, an acidic sequence in PEP-19 is required to modulate Ca2+ binding and to sensitize HeLa cells to ATP-induced Ca2+ release. Here, we report the NMR solution structure of a complex between PEP-19 and the C-domain of apo CaM. ...

Increased susceptibility of birds to avian pathogens in intensive husbandry system has emphasized on necessity of improvement of innate and specific immune responses of birds by the fast establishment of a beneficial microflora and immune stimulator factors to guarantee healthy and low-price products. During this study, 192 one-day-old broiler chicks (Ross-380) in four groups with three replica...

In Arabidopsis leaf coloration mutants, the delayed greening phenomenon is common. Nonetheless, the mechanism remains largely elusive. Here, a delayed greening mutant fln2-4 of FLN2 (Fructokinase-Like Protein2) was studied. FLN2 is one component of Transcriptionally Active Chromosome (TAC) complex which is thought to contain the complete plastid-encoded polymerase (PEP). fln2-4 displayed albino...

BACKGROUND Positive expiratory pressure (PEP) is regularly used as a self-administered airway clearance technique. OBJECTIVE The aim of this study was to evaluate the need to teach the correct use of the PEP device and to measure the progress of the success rate of the maneuver after training. METHOD A PEP system (PariPEP-S Sytem) was used to generate PEP in 30 healthy volunteers. They were...
