HS2324+3944 is a peculiar PG1159 star, with a high amount of H in its atmosphere (Dreizler et al. 1995). Its location in the logTeff – log g plane is well inside the GW Vir instability strip. In this paper I report the results of two photoelectric observations of HS 2324+39, which clearly show that the luminosity of this star presents periodical variations with a period of (2140 ± 11) s. This p...

Background: The process of inflammation induces hepatic synthesis of various acute phase proteins such as high sensitivity C-reactive protein (hs-CRP) which is believed to play a role in insulin resistance. Higher incidence of type-2 diabetes mellitus has been observed with high levels of hs-CRP. Objectives: The present case control study was under taken to 1. Find the serum hs-CRP levels in ty...

* The cpr5-1 Arabidopsis thaliana mutant exhibits constitutive activation of salicylic acid (SA), jasmonic acid (JA) and ethylene (ET) signalling pathways and displays enhanced tolerance of heat stress (HS). * cpr5-1 crossed with jar1-1 (a JA-amino acid synthetase) was compromised in basal thermotolerance, as were the mutants opr3 (mutated in OPDA reductase3) and coi1-1 (affected in an E3 ubiqu...

Previous analyses of the distribution of heat shock (hs) proteins in soybean (Glycine max L. Merr., var Wayne) have demonstrated that a fraction of the low molecular weight hs protein associates with ribosomes during hs. To more specifically characterize the nature of this association, isokinetic centrifugation of ribosomes through sucrose gradients was used to separate monosomes from polysomes...

Mast cells are widely distributed in perivascular connective tissues, especially in areas of active tumor growth and vascular reactivity. Incubation of metabolically [35S]O4 = -labeled subendothelial extracellular matrix (ECM) with lysates of bone marrow-derived mouse mast cells (BMMC) resulted in extensive degradation of heparan sulfate (HS) into fragments 5 to 6 times smaller than intact HS s...

In 2008, Hashimoto and Sakurai proposed a new efficient signature scheme, which is a non-commutative ring version of Shamir’s birational permutation signature scheme. Shamir’s scheme is a generalization of the OSS (Ong-Schnorr-Shamir) signature scheme and was broken by Coppersmith et al. using its linearity and commutativity. The HS (Hashimoto-Sakurai) scheme is expected to be secure against th...

Exercise is one of the best therapies, if not the best, for the prevention and treatment of type 2 diabetes. Kondo, Araki, Kai and colleagues, in this issue of EBioMedicine, introduce a device that mimics exercise (1). When applied to subjects with metabolic syndrome (MS) or type 2 diabetes (t2DM) the therapy improves the diverse parameters inherit to metabolic syndrome (MS) and type 2 diabetes...

The syndecans are transmembrane heparan sulfate (HS) proteoglycans expressed on all adherent cells (Bernfield et al., 1999; Rapraeger and Ott, 1998). A family of four, they have diverse functions ranging from participation in cell–cell adhesion, regulation of the signaling of HS binding growth factors, and organization of cell–matrix adhesion and signaling. A paper published in this issue of Th...

To cause infections, microbial pathogens elaborate a multitude of factors that interact with host components. Using these host–pathogen interactions to their advantage, pathogens attach, invade, disseminate, and evade host defense mechanisms to promote their survival in the hostile host environment. Many viruses, bacteria, and parasites express adhesins that bind to cell surface heparan sulfate...

این پژوهش با الهام گرفتن از نتایج یک طرح مطالعاتی کاربردی، رویکرد سلسله­‌مراتبی جهت پیگیری فرایند توسعه تأمین‌کنندگان و حمایت تصمیمات موجود در هر مراحل آن ارائه‌ می‌کند. ابتدا، زمینه‌های تأمین نیازمند سپس واجد شرایط هریک زمینه‌ها به کمک تصمیم‌گیری چندشاخصه بهترین-بدترین مشخص می‌گردند. معیارهای شناسایی نیز مرور مطالعات پیشین بهره‌گیری نظرات خبرگان حوزه‌ی خرید استخراج‌شده‌اند. درنهایت، مدل ریاضی ...
