to determine the effects of steckling weight and planting density on seed quantitative and qualitative characteristics of monogerm sugar beet c.v. 9597, this experiment was carried out in ardabil agricultural research station in two years (1998-99). in this study, steckling weight with three different sizes(including 4.5 mm seed portion, velocity and unifomity of germination and decreasing of g...

Objective: The high global incidence of type 2 diabetes has challenged researchers to establish animal models that resemble the chronic stage observed in type 2 diabetes patients. One such model is induced by neonatal streptozotocin (n-STZ) administration to rat pups at 0, 2, or 5 days after birth. In this study, we assessed Ins-1 gene expression and tissue insulin levels as well as serum conce...

3-[5-{2-(2,3-Dihydroxyprop-1-yl)-o-carboran-1-yl}pentan-1-yl]thymidine (N5-2OH) is a first generation 3-carboranyl thymidine analog (3CTA) that has been intensively studied as a boron-10 ((10)B) delivery agent for neutron capture therapy (NCT). N5-2OH is an excellent substrate of thymidine kinase 1 and its favorable biodistribution profile in rodents led to successful preclinical NCT of rats be...

Hyperhalogens are a class of highly electronegative molecules whose electron affinities even exceed those of their superhalogen ligands. Such species can serve as new oxidizing agents, biocatalysts, and building blocks of unusual salts, and hence are important to the chemical industry. Utilizing stable N5(-) as the ligand, a series of aromatic hyperhalogen anions, namely mononuclear M(N5)(k+1)(...

Only recently, with the identification of antibodies to a 43-kDa muscle autoantigen, subsequently identified as cytoplasmic 50-nucleotidase 1A (cN1A) in sera from patients with inclusion body myositis (IBM), has a role for B-cell autoimmunity in IBM been demonstrated. IgG antibodies to cN1A have> 90% specificity and 34%–70% sensitivity in IBM. Detection of all 3 isotypes (IgG, IgM, and IgA) by ...

effects of different planting on phenology, grain yield and its components of two sunflower culitvars were investigated. in 1996, an experiment was conducted in the experimental field of azad islamic university of khorasgan, located in khatonabad village, isfahan. the experiment was arranged in a randomized complete block design with a split plot layaout and four replications. the main plots co...

In a replicated field plot experiment, the population density of Meloidogyne incognita was monitored biweekly through the overwintering period (December through April) between soybean crops. The population survived as second-stage juveniles whose numbers remained stable through the winter months and did not decline until February. The yields of plots planted with a M. incognita susceptible cult...

To induce differentiation of embryonic stem cells (ESCs) into specialized cell types for therapeutic purposes, it may be desirable to combine genetic manipulation and appropriate differentiation signals. We studied the induction of dopaminergic (DA) neurons from mouse ESCs by overexpressing the transcription factor Nurr1 and coculturing with PA6 stromal cells. Nurr1-expressing ESCs (N2 and N5) ...
