Introduction HIV post-exposure prophylaxis (PEP) involves taking antiretroviral medication after potential exposure to HIV to reduce the probability of becoming infected. New York State recommends PEP following certain occupational (e.g., needle sticks by healthcare workers) and non-occupational (e.g., sexual and needle-sharing activities) exposures.1 Little information exists on the uptake of ...

PEP-19/PCP4 maps within the Down syndrome critical region and encodes a small, predominantly neuronal, IQ motif protein. Pep-19 binds calmodulin and inhibits calmodulin-dependent signaling, which is critical for synaptic function, and therefore alterations in Pep-19 levels may affect synaptic plasticity and behavior. To investigate its possible role, we generated and characterized pep-19/pcp4-n...

Peplomycin emulsified in hydroxypropyl cellulosum (HPC-PEP) was prepared for intravesical chemotherapy. Clinical efficacy of HPC-PEP and tissue concentration of peplomycin (PEP) were studied in 12 patients with bladder tumor. Histopathology showed transitional cell carcinoma; 2 in grade 1,8 in grade 2, and 2 in grade 3. The total volume of 30 ml HPC-PEP was prepared from a mixture of 2% HPC and...

Rabbit antisera evoked by type 5 streptococcal M protein (M5) were screened by enzyme-linked immunosorbent assay (ELISA) for immunological cross-reactivity with purified rabbit muscle phosphorylases a and b. Of 10 pep M5 antisera tested, 3 showed significant cross-reactivity with both forms of the enzyme. ELISA inhibition studies using one of the pep M5 antisera showed that all of the phosphory...

BACKGROUND AND OBJECTIVES Birthweight differences between kwashiorkor and marasmus suggest that intrauterine factors influence the development of these syndromes of malnutrition and may modulate risk of obesity through dietary intake. We tested the hypotheses that the target protein intake in adulthood is associated with birthweight, and that protein leveraging to maintain this target protein i...

HYPOTHESIS We hypothesized that aerosol distribution in the lungs of patients with cystic fibrosis changes with positive expiratory pressure (PEP). METHODS Eight patients were randomized to one of 2 conditions. On one study day, patients inhaled saline aerosol containing 99mtechnetium generated by a Pari LC Plus nebulizer and exhaled through a Pari PEP device. On another day, the same patient...

BACKGROUND In 2009, national guidelines for hepatitis A control in Australia changed to recommend hepatitis A vaccine (HAV), instead of normal human immune globulin (NHIG), for post-exposure prophylaxis (PEP). AIMS (1) Determine whether the uptake of PEP among contacts of hepatitis A cases changed after the introduction of the new guidelines, and (2) assess the field effectiveness of the HAV ...

BACKGROUND There is limited evidence on the efficacy of post-exposure prophylaxis (PEP) for sexual exposures. We sought to determine the factors associated with adherence to treatment and describe the incidence of PEP failures in a Montreal clinic. METHODS We prospectively assessed all patients consulting for PEP following sexual exposures from October 2000 to July 2014. Patients were followe...

peroxisomes are small size organelles in nearly all eukaryotic cells involved in various metabolic functions including β-oxidation of very long chain fatty acids and metabolite peroxidation and plasmalogens synthesis. the latter is one of the major constituents in neural cell membranes. the biogenesis of peroxisomes is a complex process which requires multiple proteins encoded by pex genes. dys...

BACKGROUND & AIMS Advanced techniques have been developed to overcome difficult cannulation cases in endoscopic retrograde cholangiopancreatography (ERCP). Pancreatic duct guidewire placement method (PGW) is performed in difficult cannulation cases; it is possible that it places patients at risk of post-ERCP pancreatitis (PEP). The mechanism of PEP is still unclear, but pancreatic duct pressure...
