The incidence of human immunodeficiency virus (HIV) infection continues to rise among core groups and efforts to reduce the numbers of new infections are being redoubled. Post-exposure prophylaxis (PEP) is the use of short-term antiretroviral therapy (ART) to reduce the risk of acquisition of HIV infection following exposure. Current guidelines recommend a 28-day course of ART within 36-72 hour...

Glioma presents one of the most malignant brain tumors, and the therapeutic effect is often limited due to the existence of brain tumor barrier. Based on interleukin-13 receptor α2 (IL-13Rα2) over-expression on glioma cell, it was demonstrated to be a potential receptor for glioma targeting. In this study, Pep-1-conjugated PEGylated nanoparticles loaded with paclitaxel (Pep-NP-PTX) were develop...

Illumination of previously darkened maize (Zea mays L. cv Golden Cross Bantam T51) leaves had no effect on the concentration of phosphoenolpyruvate (PEP) carboxylase protein, but increased enzyme activity about 2-fold when assayed under suboptimal conditions (pH 7.0 and limiting PEP). In addition, sensitivity to effectors of PEP carboxylase activity was significantly altered; e.g. malate inhibi...

Potentially eventually positive (PEP) sign patterns were introduced in “Sign patterns 1 that allow eventual positivity,” Electronic Journal of Linear Algebra, 19 (2010): 108–120, where it 2 was noted that A is PEP if its positive part is primitive, and an example was given of a 3× 3 PEP 3 sign pattern with reducible positive part. We extend these results by constructing n × n PEP sign 4 pattern...

BACKGROUND Nebulized hypertonic saline is a highly effective therapy for patients with cystic fibrosis (CF), yet 10% of patients are intolerant of hypertonic saline administered via jet nebulizer. Positive expiratory pressure (PEP) nebulizers splint open the airways and offers a more controlled rate of nebulization. METHODS In 4 consecutive adult CF patients who were intolerant of hypertonic ...

The transplantation of neural stem cells (NSCs) has been demonstrated as a potential treatment strategy for traumatic brain injury (TBI). Cu, Zn-superoxide dismutase (SOD1) is an important antioxidant enzyme that detoxifies intracellular reactive oxygen species, thereby protecting cells from oxidative damage. PEP-1, a peptide carrier, is able to deliver full-length native peptides or proteins i...

3-Deoxy-d-manno-octulosonate 8-phosphate (KDO8P) synthase catalyzes the condensation of arabinose 5-phosphate (A5P) and phosphoenolpyruvate (PEP) to form KDO8P, a key precursor in the biosynthesis of the endotoxin of Gram-negative bacteria. Earlier studies have established that the condensation occurs with a syn addition of water to the si side of C2(PEP) and of C3(PEP) to the re side of C1(A5P...

PURPOSE This study aims to identify the clinical significance of serum autoantibodies against dickkopf-1 (DKK1) and evaluate their feasibility in the immunodiagnosis and prognosis of non-small cell lung cancer (NSCLC). EXPERIMENTAL DESIGN Epitope mapping by peptide microarray-based serum screening of NSCLC patients (n=72) and healthy controls (n=16) was performed. Indirect ELISA with peptides...

BACKGROUND Patients with cystic fibrosis perform airway clearance techniques and receive nebulized medications on a regular basis. Some positive expiratory pressure (PEP) devices allow concomitant administration of aerosol. I hypothesized that this practice alters the aerosol characteristics and patient dose. I compared the aerosol characteristics and patient dose of nebulized albuterol from 2 ...

The study investigated the relationship between self-focused attention (SFA) and post-event processing (PEP) in social anxiety. SFA is the process of directing attention to internal stimuli during a social interaction. PEP is a detailed review of performance following an interaction. Highly socially anxious students (N = 82) were randomly assigned to a high SFA (n = 40) or low SFA condition (n ...
