Recently, artificial ribonucleases (aRNases)--conjugates of oligodeoxyribonucleotides and peptide (LR)(4)-G-amide--were designed and assessed in terms of the activity and specificity of RNA cleavage. The conjugates were shown to cleave RNA at Pyr-A and G-X sequences. Variations of oligonucleotide length and sequence, peptide and linker structure led to the development of conjugates exhibiting G...

This article and the subsequent one suggest that the currently accepted view of a simplistic (direct) relationship between encephalitis lethargica (EL) and postencephalitic Parkinsonism (PEP) is based on a incomplete evaluation of the epidemic period literature. In this article we provide a detailed analysis of the literature from the period that demonstrates that Parkinsonism was not initially...

This guideline is an update of the post-exposure prophylaxis (PEP) guideline published by the Southern African HIV Clinicians Society in 2008. It updates the recommendations on the use of antiretroviral medications to prevent individuals who have been exposed to a potential HIV source, via either occupational or non-occupational exposure, from becoming infected with HIV. No distinction is made ...

Background. The aim of this study was to understand the use and distribution of human rabies post exposure prophylaxis (PEP) vaccination in Izmir. Methods. A retrospective analysis of the files of all patients who consulted for rabies PEP at the Infectious Diseases Clinic of Karsiyaka State Hospiltal in Izmir, Turkey, between January 2013 and June 2013 was conducted. Results. PEP data were eval...

Pistil final morphology relies on floral meristem homeostasis, proper organ specification and regional differentiation. These are developmental processes in which sophisticated signaling networks are being uncovered. However, further elements for fine-tuning adjustment still remain to be disclosed. At the molecular level, posttranscriptional modulators may fit such a profile. In this work, we d...

BACKGROUND Acute pancreatitis is a common complication of endoscopic retrograde cholangiopancreatography and the benefit of its pharmacological treatment is unclear. Although prophylactic use of gabexate for the reduction of pancreatic injury after ERCP has been evaluated, the discrepancy about gabexate's beneficial effect on pancreatic injury still exists. This study aimed to evaluate the effe...

BACKGROUND AND OBJECTIVE Prolyl endopeptidase (PEP) (EC 3.4.21.26) is a serine peptidase involved in differentiation, development and proliferation processes of several tissues. Recent studies have demonstrated the increased expression and activity of this cytosolic enzyme in colorectal cancer (CRC). However, there are no available data about the impact of this peptidase in the biological aggre...

Coxiella burnetii is a category B bioterrorism agent. We numerically evaluated the risks and benefits from postexposure prophylaxis (PEP) after an intentional release of C. burnetii to the general population, pregnant women, and other high-risk populations. For each group, we constructed a decision tree to estimate illness and deaths averted by use of PEP/100,000 population. We calculated the t...

Experimental autoimmune uveitis (EAU) is a well established model for immune-mediated organ-specific disease. Our group has recently shown that the M. leprae Hsp65 aggravated the uveitis in mice; in the present study, we evaluated the action of M. leprae  K(409)A mutant protein and the synthetic peptides Leader pep and K(409)A pep (covering amino acids residues 352-371 of WT and K(409)A protein...
