the effects of sucrose and some regulators on freezing tolerance in chickpea studied. four weeks in vitro explants were cultured in three different ms media without growth regulators and with normal level of sucrose (30 gl-1) (a), without growth regulators and with reduced sucrose (10 gl-1) (b) and medium supplemented with lmg gl-1 bap and 0.1 mgi1 iba and with 30 gi-1sucrose (c) for two weeks....

objective: to evaluate the prevalence of gestational diabetes mellitus (gdm) and its risk factors in tehran. materials and methods: from march 2002 to october 2004, screening for gdm was performed on 1804 women in tehran. all pregnant women were referred for a 50 g oral glucose challenge test (ogct) between 24th and 28th week of gestation. all subjects with an abnormal gct (blood glucose level ...

materials and methods statistical and regressive modeling methods were used to investigate the effects of the carbon source and to optimize the production media. results the spinosad production of s. spinosa co121 increased 77.13%, from 310.44 ± 21.84 μg/ml in the initial fermentation medium (with glucose as the main carbon source) to 549.89 ± 38.59 μg/ml in a new optimized fermentation medium ...

A series of glycan-coated quantum dots were prepared to probe the effect of glycan presentation in intracellular localization in HeLa and SV40 epithelial cells. We show that glycan density mostly impacts on cell toxicity, whereas glycan type affects the cell uptake and intracellular localization. Moreover, we show that lactose can act as a "Trojan horse" on bi-functionalized QDs to help intrace...

Maternal prenatal screening for group B streptococci (GBS) followed by offering of intrapartum chemoprophylaxis to carriers is one of the strategies used to reduce the incidence of neonatal early-onset GBS infections. Culturing of vaginal and anorectal swab specimens in selective broth is the screening procedure recommended by the Centers for Disease Control and Prevention. This technique is se...
