A system for measurement and calibration of nonorthogonal joints and limbs in humans.

Human limbs are a multilinked system in which the revolute joints are not orthogonal to the limb segments or to each other. The standard method for movements of multilinked systems is the Denavit-Hartenberg (DH) representation, which is useful for orthogonal systems. When applied to non-orthogonal systems, the DH representation projects the reference frames outside of the limb segments.

Hemopressin, a hemoglobin fragment, dilates the rat systemic vascular bed through release of nitric oxide.

The present study was undertaken to investigate the effects of intravenous (i.v.) administration of rat hemopressin (rHP), 30-1000 microg/kg, on systemic arterial pressure (SAP), cardiac output (CO) and systemic vascular resistance (SVR) in the anesthetized rat.

Intermedin/adrenomedullin-2 dilates the rat pulmonary vascular bed: dependence on CGRP receptors and nitric oxide release.

Intermedin/adrenomedullin-2 (IMD/AM2) is a 47 amino acid peptide formed by enzymatic degradation of preprointermedin. The present study was undertaken to investigate the effects of rat IMD (rIMD) in the isolated buffer perfused rat lung (IBPR) under resting conditions and under conditions of elevated pulmonary vasoconstrictor tone (PVT). Under resting conditions in the IBPR, rIMD had little or no activity.
