In this article, we consider and discuss some properties of the positive
 solutions to following rational nonlinear DE ${x_{n+1}}=\frac{{\alpha {%

An inclusion complex consisting of a fluorescent phenylboronic acid (C1-APB) and beta-cyclodextrin (beta-CD) acts as a supramolecular saccharide sensor whose response mechanism is based on photoinduced electron transfer (PET). This study evaluated four kinds of cyclodextrins (alpha-CD, beta-CD, gamma-CD, and NH(2)-beta-CD) by comparing their pH profiles, and confirmed that beta-CD was the best ...

We determined the relative contribution of beta 1- and beta 2-adrenoceptor stimulation to the positive inotropic responses of human atrial myocardium to catecholamines. (-)Norepinephrine produced stimulation predominantly through beta 1-receptors and (-)epinephrine through both beta 1- and beta 2-receptors. However, there were marked differences in the responses of tissues from patients treated...

We give the necessary and sufficient conditions for weighted inequality \begin{document}$ \begin{equation*} \||x|^{-b} T_{{\alpha}_{1}, \dots, {\alpha}_{m}, {\beta}_{1}, {\beta}_{m}, {\gamma}_{1}, {\gamma}_{m}}f \|_{L^q(\mathbb{R}^{n})} \leq C \||x|^{a} f\|_{L^p(\mathbb{R}^{n})} \end{equation*} $\end{document} both inside outside scaling regime of singular operator$ {\gamma}_{m}}f(x): = \int_{\...

The nature of beta adrenergic receptors in human cerebral arteries was characterized and alteration of these receptors after subarachnoid hemorrhage was examined using a radioligand binding assay. The specific 3H-dihydroalprenolol, a beta adrenergic antagonist, binding to human cerebral arteries was saturable and of high affinity (KD = 12.3 nM) with a Bmax of 790 fmol/mg protein. Ki values and ...

background and objective: organisms producing ctx-m β-lactamases are emerging as a source of resistance to oxyiminocefalosporins such as ceftriaxone and ceftazidime. however, the laboratory detection of these strains is not well defined. in this study, phenotypic assay for screening of extended-spectrum β-lactamases producing strains and molecular assay for the identification of ctx-m β-lactama...
