The astronomical site parameters for the Magdalena Ridge Observatory (MRO) are being studied from numerous aspects including meteorological, environmental, seismic and sky quality (e.g. “seeing”, cloud cover). Results to date indicate that MRO is an excellent site for astronomical observing. Seeing measurements of less that 1 arc second in the optical are routinely obtained. Seismic conditions ...

According to the authors, breast augmentation can be safely performed with the use of well-monitored sedation anesthesia. They credit this method with a brief recovery period, fast return to normal activity, minimal discomfort, and more safety and convenience than general anesthesia.

In this study, 22 patients (15-75 years old) were selected and transferred to CT scan for tumor ablation. For ablations, after prep and drep under the local anesthesia and mild sedation in proper position, small incision made and special needle inserted and guided by proper direction to the core of the tumor. Then, laser probe inserted through the needle and laser energy delivered. Although we ...

Cardiac electrophysiologic effects of verapamil in vivo are the result of both direct and indirect actions on the heart (the latter due to augmentation of sympathetic neural tone, diminution of parasympathetic neural tone, and increased circulating catecholamines). In this study we assessed the interaction of verapamil's direct and indirect actions on electrophysiologic properties of the heart ...

BACKGROUND Platelet-associated epidermal growth factor (EGF) and transforming growth factor-beta (TGF-beta) can augment synthesis of plasminogen activator inhibitor type 1 (PAI-1). Accordingly, exacerbation of atherogenesis may accompany release of platelet-associated growth factors (or mitogens) occurring in association with occult, repetitive thrombosis and thrombolysis. In the Helsinki prima...

The results of quantitative PCR (qPCR) presented in the paper clearly demonstrate that the sixteen-fold genome reduction inCyclops kolensisduring chromatin diminution (from 15.3 pg to 0.98 pg) results in a dramatic decrease in ribosomal RNA gene copy numbers in the genome of a somatic cell line by more than two orders of magnitude. The results presented allow for the consideration of the chroma...

Increased generation of reactive oxygen species contribute to endothelial dysfunction in atherosclerosis, hypertension and heart failure. Recently, it was suggested that bursts of superoxide anions may inactivate endothelial surface-bound enzymes such as angiotensin converting enzyme (ACE). Here, we tested effects of xanthine/xanthine oxidase-derived superoxide anions on vascular responses and ...

The intraaortic balloon pump (IABP) has been employed in the management of five patients with ventricular septal rupture (VSD) and six patients with acute mitral regurgitation (AMR) following myocardial infarction. All patients were in cardiogenic shock which responded poorly to medical therapy including pressor and inotropic agents. IABP resulted in significant clinical and hemodynamic improve...

Hypercapnia induces cerebral vasodilation and increases cerebral blood flow (CBF), and hypocapnia induces cerebral vasoconstriction and decreases CBF. The relation between changes in CBF and cerebral blood volume (CBV) during hypercapnia and hypocapnia in humans, however, is not clear. Both CBF and CBV were measured at rest and during hypercapnia and hypocapnia in nine healthy subjects by posit...
