Isothermal calorimetric titration of 18-crown-6 ether with BaCl2 in pure aqueous solution over the temperature range 7-40 degrees C gives precise binding constants and enthalpy changes. Nonlinear least-squares fitting of the binding constants to the integrated van't Hoff equation, including a temperature-independent change in heat capacity, leads to van't Hoff enthalpies that differ significant...
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...
The vascular endothelium plays an essential role in the control of the blood flow. Pharmacological agents like quinone (menadione) at various doses modulate this process in a variety of ways. In this study, Q7, a 2-phenylamino-1,4-naphthoquinone derivative, significantly increased oxidative stress and induced vascular dysfunction at concentrations that were not cytotoxic to endothelial or vascu...
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...
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...
Nguyen, Thien-Son, H. Richard Winn, and Damir Janigro. ATP-sensitive potassium channels may participate in the coupling of neuronal activity and cerebrovascular tone. Am. J. Physiol. Heart Circ. Physiol. 278: H878–H885, 2000.—K1 dilate and constrict cerebral vessels in a dosedependent fashion. Modest elevations of abluminal K1 cause vasodilatation, whereas larger extracellular K1 concentration ...
