Pep M5, the pepsin-derived N-terminal half of the group A streptococcal type 5 M protein exhibits immunologic crossreaction with type 6 M protein, localizing some of the M6-crossreactive epitope(s) within this segment of the M5 protein. Based on the amino acid sequence of the Pep M5 protein, two structurally distinct domains have been recognized within its coiled-coil structure. We have now fou...

Rabies claims approximately 59,000 human lives annually and is a potential risk to 3.3 billion people in over 100 countries worldwide. Despite being fatal in almost 100% of cases, human rabies can be prevented by vaccinating dogs, the most common vector, and the timely administration of post-exposure prophylaxis (PEP) to exposed victims. For the control and prevention of human rabies in N'Djame...

Many gluten peptides elicit proliferative responses from T cells from Celiac Sprue patients, influencing the pathogenesis of this small intestinal disorder. These peptides are Pro- and Gln-rich in character, suggesting that resistance to proteolysis promotes their toxicity. To test this hypothesis, we analyzed the digestive resistance of a panel of alpha- and gamma-gliadin peptides believed to ...

OBJECTIVES Acute pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP) is a severe complication with substantial morbidity and mortality. Indomethacin has been identified to prevent this complication; however, the results using indomethacin have varied. Therefore, we performed a meta-analysis on the efficacy of rectally administered indomethacin in the prevention of post-ERCP...

It has not been well elucidated whether patients with measles who have undergone postexposure prophylaxis (PEP) exhibit milder clinical symptoms than would be expected in the absence of PEP. In the present study, we compared the severity of measles of patients who had undergone incidental PEP to those of patients who had not received such prophylaxis. An outbreak of measles occurred among the p...

BACKGROUND The efficacy of antiretrovirals as postexposure prophylaxis (PEP) to prevent viral acquisition was demonstrated in nonhuman primate models of human immunodeficiency virus (HIV) in the early 1990s. To complement the evidence base for efficacy of HIV PEP in humans, we systematically reviewed the published data on PEP efficacy across animal studies. METHODS PubMed, Web of Science, and...

OBJECTIVES In the course of studies to identify novel treatment strategies against the pathogenic bacterium, Chlamydia, we tested the carrier peptide, Pep-1, for activity against an intracellular infection. METHODS Using a cell culture model of Chlamydia trachomatis infection, the effect of Pep-1 was measured by incubating the peptide with extracellular chlamydiae prior to infection, or by ad...

BACKGROUND HIV/AIDS infection in health care facility has become a major health problem. Especially in resource poor setting health care workers are managing huge number of HIV infected patients that made them to be more exposed to HIV infection. This situation makes the use of post exposure prophylaxis for HIV very important. Therefore the aim of the study was to assess knowledge, attitude and...

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...
