Cardiac calsequestrin (Casq2) is thought to be the key sarcoplasmic reticulum (SR) Ca2+ storage protein essential for SR Ca2+ release in mammalian heart. Human CASQ2 mutations are associated with catecholaminergic ventricular tachycardia. However, homozygous mutation carriers presumably lacking functional Casq2 display surprisingly normal cardiac contractility. Here we show that Casq2-null mice...
The small intestine contributes to diabetic dyslipidemia through the overproduction of apolipoprotein B48 (apoB48)-containing chylomicron particles. An important regulator of chylomicron generation is dietary lipid absorption, underlining the potential involvement of intestinal lipid transporters for developing dyslipidemia. Intestinal expression of scavenger receptor class B type I (SR-BI) has...
objective(s): hardystonite (ht) is zn-modified silicate bioceramics with promising results for bone tissue regeneration. however, ht possesses no obvious apatite formation. thus, in this study we incorporated sr and ti into ht to prepare sr-ti-hardystonite (sr-ti-ht) nanocomposite and evaluated its in vitro bioactivity with the purpose of developing a more bioactive bone substitute material. ma...
Previous ventricular myocyte studies indicated that ryanodine receptors (RyRs) are in the sarcoplasmic reticulum (SR) and are critical in excitation–contraction coupling, whereas the inositol trisphosphate (InsP3) receptors are separately localized on the nuclear envelope (NucEn) and involved in nuclear Ca signaling. Here, we find that both caffeine and InsP3 receptor agonists deplete free [Ca ...
The decolorization of direct Solophenyl red 3BL (SR), a polyazo dye extensively used in textile industry was studied. The Fomes fomentarius laccase alone did not decolorize SR. The natural redox mediator, acetosyringone (AS), was necessary for decolorization to occur. Box-Behnken design was used to evaluate the effects of three parameters, namely, enzyme concentration (0.5-2.5 U mL(-1)), redox ...
در این پژوهش نانوپودر های سری ترکیبات (45/0، 3/0، 15/0، 1/0=x ) به روش فعال سازی مکانیکی و گرمادهی ساخته شد. مواد اولیه مورد استفاده bao، sro، بود که با نسبت گلوله به پودر 1:10، در ظرف آسیا همراه گلوله های فولادی به قطر mm11 آسیا شدند. بررسی ساختاری نشان داد که ساختار پروسکایت این ترکیب بعد از ? ساعت آسیا کاری، در دمای اتاق و با گرمادهی در کوره با دمای به مدت 2 ساعت، تشکیل می شود. همچنین نتایج...
Systematic reviews (SR) are a strategic resource for many who may assume that comprehensive computer searches are used to identify the studies that are used in SR. The current study assessed the reports of comprehensive computer searching in SR in psychology. Comprehensive computer search methods listed as basic in SR manuals and publications of major SR organizations (e.g., Cochrane Collaborat...
High precision measurements of Sr/Ca in planktonic foraminifera for the last 150 ka reveal Sr/Ca variations of up to 12% on glacial/interglacial time scales. Although records showing the largest variations appear to be strongly influenced by selective dissolution, other records show Sr/Ca variations of 3–5% that do not covary with indicators of dissolution intensity and that are reproduced in s...
A CONSISTENT OBSERVATION with fatigue in skeletal muscle is a decline in the amplitude of the myoplasmic Ca transient, which is thought to result primarily from a reduced Ca flux through the ryanodine receptor (RyR1) of the sarcoplasmic reticulum (SR) (Fig. 1). This in turn is thought to contribute to the loss in muscle force and power (2). In the past 20 years, the important proteins at the t-...
