Segments of rat aortic arch were studied to determine the existence of sexual dimorphism.
The influence of the endothelium in mediating gender differences in contractility (maximum …

In the presence of indomethacin, arachidonic acid relaxes pre-contracted rings of rat aorta
only when the endothelium is intact. Arachidonate-induced, endothelium-dependent …

The pulmonaryarteriesof rats were studiedinorderto determine the existence of sexual
dimorphism. Gender differences, in the sensitivity (EC@) and maximum contractility (T,,,@) of ring …

L-arginine has been proposed to be the precursor of the endothelium-derived relaxing factor.
In this study, we evaluated the pulmonary vascular effects of L-arginine-HCl and its …

Eicosanoids such as thromboxanes (Txs) and leukotrienes (LTs) are powerful spas-mogens.
The pulmonary hemodynamic actions of leukotrienes are complex. For example, in the …

Rats exposed to 20 Gy whole-body irradiation demonstrated a depressed aortic responsiveness
to the thromboxane mimic, U46619, 48 h postirradiation. The mechanism for this …

Exposure to ionizing radiation has demonstrated that vascular tissue is very radiosensitive (1–3).
Besides structural changes, ionizing radiation exposure alters vascular permeability (2,…

… DBH ≥10 cm. Within the 5 m radius plot we measured the DBH of every tree <10 and ≥4
cm DBH, and also tallied all of the trees that were ≥2 m in height, but <4 cm DBH. Abundance …

It is one of the ironies of medical practice that as physicians we can competently and confidently
treat diseases of whose pathogenesis we remain woefully ignorant. Such is the case …

An explosive formulation containing fine tungsten particles mixed with HMX was detonated.
Samples of the tungsten powder were recovered and investigated to characterize the …
