HIV screening practices for living organ donors, New York State, 2010: need for standard policies.

Our survey of kidney and liver transplant centers in New York State found a wide variation among transplant centers in evaluation and screening for HIV risk and infection among prospective living donors. Survey results underscore the need to standardize practices. A recent transmission of human immunodeficiency virus (HIV) from a living donor to a kidney recipient revealed a possible limitation in existing screening protocols for HIV infection in living donors.

Biosynthesis of sulfidopeptide leukotrienes via the transfer of leukotriene A4 from polymorphonuclear cells to bovine retinal pericytes.

Administration of exogenous sulfidopeptide leukotrienes (LTs) is associated with enhanced microvascular permeability. In addition, endogenous LTs have been implicated as participants in permeability (nonhydrostatic) edema formation. The source of LTs for interaction with the microvasculature is, however, unknown.

Nitric oxide opposes phorbol ester-induced increases in pulmonary microvascular permeability in dogs.

In addition to its effects on vascular tone, nitric oxide (NO) has been suggested to function as a participant in fluid homeostasis affecting interactions between the endothelium and circulating inflammatory cells. The role of NO in the increased microvascular permeability of acute lung injury, however, remains controversial. We investigated the hypothesis that NO opposes increases in pulmonary vascular permeability after phorbol myristate acetate administration, i.

Modulation of synovial blood flow by the calcitonin gene-related peptide (CGRP) receptor antagonist, CGRP(8-37).

1. The effect of the calcitonin gene-related peptide (CGRP) receptor antagonist, CGRP(8-37) on blood flow in the knee joint of the anaesthetized rat was investigated. 2.
