Since 1988, institutions have been offering antiretroviral postexposure prophylaxis (PEP) for occupational exposures to HIV (1,2). Although much has been accomplished since 1990, many important questions remain: What are the initiating events in the pathogenesis of occupational HIV infection associated with a percutaneous exposure? What evidence supports the effectiveness of PEP in preventing o...

This report updates U.S. Public Health Service recommendations for the management of health-care personnel (HCP) who have occupational exposure to blood and other body fluids that might contain human immunodeficiency virus (HIV). Although the principles of exposure management remain unchanged, recommended HIV postexposure prophylaxis (PEP) regimens have been changed. This report emphasizes adhe...

Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Risk factors for post-ERCP pancreatitis (PEP) are both patient-related and procedure-related. Identification of patients at high risk for PEP is important in order to target prophylactic measures. Prevention of PEP includes administration of nonsteroidal inflammatory drugs (NSAIDs), use of spe...

In previous reports from this laboratory [ 1,2] we have shown that in guinea pig liver mitochondria there is a competition for energy between PEP and citrulline synthesis. Fatty acids are known to affect the intramitochondrial PEP* formation. Octanoate has been found to inhibit PEP production [3,4], while oleate results in a stimulation of this process [5,6] . In the present investigation the e...

Ambulatory recording of the preejection period (PEP) can be used to measure changes in cardiac sympathetic nervous system (SNS) activity under naturalistic conditions. Here, we test the ECG T-wave amplitude (TWA) as an alternative measure, using 24-h ambulatory monitoring of PEP and TWA in a sample of 564 healthy adults. The TWA showed a decrease in response to mental stress and a monotonic dec...

FK506 binding protein 12 (FK506BP) belongs to a family of immunophilins, and is involved in multiple biological processes. However, the function of FK506BP in corneal disease remains unclear. In this study, we examined the protective effects on dry eye disease in a Botulinum toxin A (BTX-A) induced mouse model, using a cell-permeable PEP-1-FK506BP protein. PEP-1-FK506BP efficiently transduced i...

BACKGROUND Functionalized gold nanoparticles are emerging as a promising nanocarrier for target specific delivery of the therapeutic molecules in a cancer cell, as a result it targeted selectively to the cancer cell and minimized the off-target effect. The functionalized nanomaterial (bio conjugate) brings novel functional properties, for example, the high payload of anticancer, antioxidant mol...

BACKGROUND The protein transduction domain (PTD) enables therapeutic proteins to directly penetrate the membranes of cells and tissues, and has been increasingly utilized. Glutaredoxin-1 (GRX-1) is an endogenous antioxidant enzyme involved in the cellular redox homeostasis system. In this study, we investigated whether PEP-1-GRX-1, a fusion protein of GRX-1 and PEP-1 peptide, a PTD, could suppr...

Este trabalho tem como título Perfil Epidemiológico De Adesão Pacientes Pós-Exposição Na Região Norte Do Brasil, onde o intuito foi buscar um total de pessoas que iniciaram tratamento da PEP (profilaxia pós exposição), verificar a adesão e descrever perfil epidemiológico dos pacientes com indicação 2018 2022. Para isso, definimos objetivo geral determinar expostos ao vírus do HIV na região nort...

We report the direct measurement of electrical transport through rod-like polymer molecules, of poly(ethyl propiolate) (PEP), utilizing single walled carbon nanotubes (SWNTs) as electrodes. The electrical properties of the devices were measured (i) before cutting a SWNT, (ii) when a SWNT was cut and (iii) after PEP deposition into the nanoscale gap in a cut SWNT. The gate-dependent electrical p...
