To date, only one crystal structure has been reported in the literature for oxalyl dihydrazide [H(2)N.NH.CO.CO.NH.NH(2)]. In the present paper, we report the discovery of four new polymorphs of oxalyl dihydrazide, obtained by crystallization from solution under different conditions, including the use of different crystallization solvents. All polymorphs have the trans-trans-trans conformation o...
background: coarctation of the aorta (coa) is a defect that accounts for 5-8% of all congenital heart diseases. balloon angioplasty as a treatment for coa is increasingly performed, with endovascular stents having been proposed as a means of improving the efficacy and safety of the procedure. the aim of this study was to evaluate the systolic blood pressure gradient at rest and during maximal e...

Moonlighting proteins Hal3 and Vhs3 form a heteromeric PPCDC with Ykl088w in yeast CoA biosynthesis.
Unlike most other organisms, the essential five-step coenzyme A biosynthetic pathway has not been fully resolved in yeast. Specifically, the genes encoding the phosphopantothenoylcysteine decarboxylase (PPCDC) activity still remain unidentified. Sequence homology analyses suggest three candidates-Ykl088w, Hal3 and Vhs3-as putative PPCDC enzymes in Saccharomyces cerevisiae. Notably, Hal3 and Vhs...
تاکنون الگوریتمها و روشهای بهینهسازی مختلفی در بهرهبرداری بهینه از مخازن با اهداف مختلف بکار گرفته شدهاند. به تازگی، از الگوریتم بهینهسازی فاخته(COA) ، به عنوان یک الگوریتم تکاملی (EA) جدید، در حل تعدادی از توابع معیار و مسائل واقعی بهرهوری گردیده، و عملکرد و توانایی بالای آن در حل مسائل بهینهسازی دشوار گزارش شده است. هدف این مقاله بررسی کارایی COA در سامانهی منابع آب، به منظور استخراج...
Cells continually adjust their gene expression profiles in order to adapt to the availability of nutrients. Glucose is a major regulator of pxancreatic β-cell function and cell growth. However, the mechanism of β-cell adaptation to high levels of glucose remains uncertain. To identify the specific targets responsible for adaptation to high levels of glucose, the differentially expressed genes f...
A complete tricarboxylic acid (TCA) cycle is generally considered necessary for energy production from the dicarboxylic acid substrates malate, succinate, and fumarate. However, a Bradyrhizobium japonicum sucA mutant that is missing a-ketoglutarate dehydrogenase is able to grow on malate as its sole source of carbon. This mutant also fixes nitrogen in symbiosis with soybean, where dicarboxylic ...
