in order to determine aqueous extract effects of cool-season turfgrass mixture clipping on germination and seedling growth of four weed species, laboratory and outdoor pot experiments were done at the experimental laboratory and greenhouse of the doroud parks and landscape organization, located in doroud, lorestan, iran. the first factor was the concentration of sport turfgrass clipping extract...
fungi produce a wide range of secondary metabolites such as antibiotics, toxins, alkaloids, fatty acids, ketones and alcohols during active cell growth. the present study was aimed to identify secondary metabolites from some penicillium species, using gc-ms. many important compounds such as 3-oxoquinuclidine in penicillium jenseii, formamidine in penicillium pusillum, orcinol and 1,3,8-p-mentha...
مقدمه: گزارش هایی مبنی بر خصوصیات آنتی دیابتیک ترکیب 4 – هیدروکسی ایزولوسین وجود دارد، اما به هرحال معرفی این ترکیب به عنوان داروی جدید نیازمند اثبات کامل اثرات مفید آن در درمان بیماری دیابت و همچنین یافتن روش های مناسب تهیه مقدار کافی از آن می باشد تا انجام مطالعات in vivo امکان پذیر شود. هدف: این پژوهش به منظور جداسازی 4 – هیدروکسی ایزولوسین از دانه شنبلیله و مقایسه مقادیر آن در دانه هایی که ...
We have examined the compositional evolution of noncoding DNA in the primate genome by comparison of lineage-specific substitutions observed in 1.8 Mb of genomic alignments of human, chimpanzee, and baboon with 6542 human single-nucleotide polymorphisms (SNPs) rooted using chimpanzee sequence. The pattern of compositional evolution, measured in terms of the numbers of GC-->AT and AT-->GC change...
The mammalian genome encodes seven guanylyl cyclases, GC-A to GC-G, that are homodimeric transmembrane receptors activated by a diverse range of endogenous ligands. These enzymes convert guanosine-5'-triphosphate the intracellular second messenger cyclic guanosine-3',5'-monophosphate (cyclic GMP). GC-A, GC-B and GC-C expressed predominantly in cardiovascular system, skeletal system intestinal e...
Group specific component (Gc) is an abundant plasma protein whose functional role is not clearly established. Gc protein is synthesised in the liver and is known to bind vitamin D, vitamin D metabolites, and G actin; Gc protein is also implicated in macrophage activation. Several polymorphic electrophoretic variants of Gc protein are found in all human populations; the most common alleles are G...
OBJECTIVE A quality improvement (QI) strategy to improve the rate of genetic counseling (GC) services was initiated in cystic fibrosis (CF) care Center E in 2010. This statewide study was conducted to determine: (1) GC rates before and after implementation of the QI strategy at Center E; (2) characteristics associated with not receiving GC; and (3) topic areas addressed during GC. METHODS The...
We recently described two eye guanylyl cyclases (GC-E and GC-F) that contain an apparent extracellular domain potentially capable of binding ligands (Yang, R.-B., Foster, D. C., Garbers, D. L., and Fülle, H.-J. (1995) Proc. Natl. Acad. Sci. U. S. A. 92, 602-606). Here, Northern and Western analyses showed that both cyclases are expressed in the retina and enriched in photoreceptor outer segment...
A sensitive and selective determination of glycyrrhizin (GC) based on surface plasmon resonance (SPR) was performed by using an anti-GC monoclonal antibody (GC-MAb) and GC-bovine serum albumin (GC-BSA) conjugate (antigen). GC-BSA was immobilized on an Au thin film of the SPR sensor chip by physical adsorption, and GC determinations were performed by an indirect competitive method. The addition ...
The human genome is composed of long stretches of DNA with distinct GC contents, called isochores or GC-content domains. A boundary between two GC-content domains in the human NF1 gene region is also a boundary between domains of early- and late-replicating sequences and of regions with high and low recombination frequencies. The perfect conservation of the GC-content distribution in this regio...
