The aim of this study is to investigate the role of chaperonin-containing t-complex polypeptide 1 beta (CCT2) in the regulation of mouse mesangial cell (mMC) contraction, proliferation, and migration with filamentous/globular-(F/G-) actin ratio under high glucose induction. A low CCT2 mMC model induced by treatment of small interference RNA was established. Groups with and without low CCT2 indu...
NO released by myenteric neurons controls the off contraction induced by electrical field stimulation (EFS) in distal esophageal smooth muscle, but in the presence of nitric oxide synthase (NOS) inhibitor, L-NAME, contraction by EFS occurs at the same time. The authors investigated the intracellular signaling pathways related with G protein and ionic channel EFS-induced contraction using cat es...
Let $\varphi=\{\varphi_k\}_{k=-\infty}^\infty$ denote the extended Takenaka--Malmquist system on unit circle $\mathbb T$ and let $\sigma_{n,\varphi}(f),$ $f\in L^1(\mathbb T)$, be Fej\'er-type operator based $\varphi$, introduced by V. N. Rusak. We give convergence criteria for $\sigma_{n,\varphi}(f)$ in Banach space $X(\mathbb T):=L^p(\mathbb T)\vee C(\mathbb $p\ge 1$. Also we prove Voronovska...
بررسی مقایسه ای پنج آزمون عملکردی اندام تحتانی در بیماران با پارگی لیگامان متقاطع قدامی و افراد سالم
این پژوهش بصورت غیرتجربی و توصیفی - تحلیلی با هدف بررسی مقایسه ای پنج آزمون عملکردی اندام تحتانی در دو گروه بیماران با پارگی لیگامان متقاطع قدامی و افراد سالم انجام شد. دراین تحقیق از پنج آزمون عملکردی زیر استفاده گردید: 1 - آزمون co-contraction semicircular . 2- آزمونcarioca . 3 - آزمون shuttle run . 4- آزمونtimed hop . 5- آزمون cross-over hop .
G. Darbo [Rend. Sem. Math. Univ. Padova, 24 (1955) 84--92] used the measure of noncompactness to investigate operators whose properties can be characterized as being intermediate between those of contraction and compact operators. In this paper, we apply the Darbo's fixed point theorem for solving infinite system of linear equations in some sequence spaces.
We prove theorems on boundedness of operators weak type $(\varphi_0, \psi_0, \varphi_1, \psi_1)$ from Lorentz space $\Lambda_{\varphi,a}(\mathbb{R}^n)$ to $\Lambda_{\varphi,b}(\mathbb{R}^n)$ in “limit” cases, when one functions $\varphi(t) / \varphi_0(t)$, \varphi_1(t)$ slowly changes at zero and infinity.
Previously, we reported that hyposmotic swelling evoked transient vascular smooth muscle cell (SMC) contraction that was completely abolished by L-type Ca(2+) channel blockers. In contrast, sustained contraction revealed in hyper- and isoosmotically-shrunken SMCs was insensitive to L-type channel blockers and was diminished in Ca(2+)-free medium by only 30-50%. Several research groups reported ...
Adenosine as a possible mediator of active hyperemia in skeletal muscle was studied in hindlimbs of dogs. Sciatic nerve stimulation decreased vascular resistance to 55 +/- 5% (mean +/- SE) of the control value in hindlimbs perfused at a constant flow rate (61 +/- 6 ml/min). Venous plasma K+ concentrations were elevated after 2 min (from 4.0 +/- 0.2 to 4.8 +/- 0.2 meq/liter; P is less than 0.005...
