BACKGROUND Color M-mode Doppler echocardiography has been suggested as a new noninvasive technique for assessing left ventricular diastolic function. The present study investigated intraventricular filling pattern by color M-mode Doppler in patients during percutaneous transluminal coronary angioplasty (PTCA). In a dog model of myocardial ischemia, the color M-mode flow pattern was related to i...

The effects of bovine skeletal muscle m-calpain and calpastatin on the degradation of casein and isolated bovine myofibrils were characterized under various pH values (7.0, 6.2, 5.7) and ionic strengths (32 to 400 mM KCl) at 25 degrees C. Caseinolytic assays indicated that m-calpain activity increased with increasing pH (P < .01) but decreased with increasing ionic strength (P < .01). Regardles...

BACKGROUND Vasospasm is a serious complication associated with subarachnoid hemorrhage. Successful management of vasospasm will ultimately depend on a clear understanding of the scope of this phenomenon, including whether arterial elements of different calibers are equally affected. We therefore examined the responses to subarachnoid hemorrhage in rabbit basilar arteries, small pial arteries, a...

Biopolymeric nanoparticles were synthesized using Gellan Gum and loaded with Atenolol, an antihypertensive drug by ionotropic gelation (an easy ecofriendly system) induced BaCl2 as ionic crosslinking agent to improve absorption bioavailability of drug. These characterized scanning electron microscope, fourier-transform infrared spectroscopy, X-ray diffraction analysis dynamic light scattering t...

with T (z) = D 1 (z)D 2 (z 01)0 D 2 (z)D 1 (z 01): The sign of Q(z) is the same as that of Re fG(z)=D1(z)g on the unit circle; an identical consideration can be made for R(z) and D 2 (z): Therefore, G(z) can be computed by finding Q(z) = Q(z 01) and R(z) = R(z 01) positive on the unit circle and such that R(z)D 1 (z) 0 Q(z)D 2 (z) = 0 8z such that T (z) = 0; jzj 1: The roots of T (z) outside th...

BACKGROUND Punica granatum Linn. (PG) is native to the Mediterranean region. Its flower exhibited antioxidant activity. The present study attempt to investigate the effect of these extract on uterine contraction and its possible mechanism(s). METHODS Thirty five female Wistar rats (200-300 g) at estrous phases of cycle was examined in this study; pieces of virgin adult rat uterus (1.5 cm) wer...
