Functional and structural heterogeneity exists among skeletal muscle vascular beds related, in part, to muscle fiber type composition. This study was designed to delineate whether the vulnerability to vascular dysfunction in insulin resistance is uniformly distributed among skeletal muscle vasculatures and whether physical activity modifies this vulnerability. Obese, hyperphagic Otsuka Long-Eva...

Hyperglycemia leads to alterations in mesangial cell function and extracellular matrix (ECM) protein accumulation. These adverse effects of glucose may be mediated by glucose metabolism through the hexosamine biosynthesis pathway (HBP). The HBP converts fructose-6-phosphate to glucosamine-6-phosphate via the rate-limiting enzyme, glutamine:fructose-6-phosphate amidotransferase (GFA). We have in...

We s(ate the following conjecture and prove it for the case where q is a proper prime power: Let A be a nonsingular n by n matrix over the finite fieM GF~, q~-4, then there exists a vector x in (GFa) ~ such that both x and ~4x have no zero component. In this note we consider-the following conjecture: Conjecture 1. Let A be a nonsingular n by n matrix over the finite field GFa, q~_4, then there ...

Mobile IP is one of the solutions for connecting mobile nodes without breaking ongoing communications. Mobile IP uses two IP addresses: one is home address and another is care-of address which is used when the mobile node is moved to another network. Although original mobile IP can support seamless roaming, it still has many problems such as packet loss during handoff and handoff latency. Those...

The use of modern neuroimaging methods to characterize the complex anatomy of brain development at different stages reveals an enormous wealth of information in understanding this highly ordered process and provides clues to detect neurological and neurobehavioral disorders that have their origin in early structural and functional cerebral maturation. Non-invasive diffusion tensor magnetic reso...

بخش اورژانس یکی از شلوغ‌ترین بخش‌های یک بیمارستان است و بهبود عملکرد این تأثیر بسیاری در کیفیت ارائه خدمات دارد. اخیراً پژوهشگران به­‌دلیل تمرکز مهندسی تاب‌آوری مدیریت ناب بر کارایی سیستم‌ها توجه بسیار زیادی به دو دیدگاه کنار یکدیگر داشته‌اند. هدف پژوهش، رویکردی یکپارچه برای ارزیابی مبتنی شاخص‌های با ارتقای رضایت شغلی کاهش هزینه‌های درمانی واحد خصوصی است. منظور، ابتدا شناسایی مؤثر، مدل مفهومی مس...

We developed an analysis pipeline enabling population studies of HARDI data, and applied it to map genetic influences on fiber architecture in 90 twin subjects. We applied tensor-driven 3D fluid registration to HARDI, resampling the spherical fiber orientation distribution functions (ODFs) in appropriate Riemannian manifolds, after ODF regularization and sharpening. Fitting structural equation ...

Controlling crystal nucleation and growth leading to formation of nano structures by an original flux treatment method mainly in calcia and magnesia crucibles followed by water-cooling allowed production of Ti45Cu45Fe10 bulky nanostructured alloy of 16mm in diameter. Since a glass forming ability (GFA) of the alloy composition is low, the alloy could not form an amorphous structure even by a co...
