Objective: To report the results of repeat fine-needle aspiration cytology (FNAC) in thyroid nodules with an initial benign cytological diagnosis that grow during follow-up and/or present suspicious ultrasonographic characteristics. Subjects and methods: The sample consisted of 456 patients with 895 nodules. FNAC was repeated after 12 to 18 months in the case of nodules with suspicious ultrason...

water is one of the most important restrictive factors in crop production. therefore, optimum use of water resources in line with sustainable agriculture is mandatory. in this research the effects of different amounts of allowed soil water depletion at various growth stages of root sugar beet and its effect on qualitative and quantitative characters of the crop were studied. the experimental de...

priming is one of the seed enhancement methods that might be resulted in increased seed performance (germination and emergence), seedling growth and plant yield under stress conditions, such as salinity, temperature and drought stress. in order to evaluate the effect of growth hormones on morphology characteristics and essential oil of basil under drought stress condition, a experiment was cond...

Random samples of this plant were taken andtheir vegetation habitat conditions and their growth characteristics including height ofcollar leaves, height of flower stem, flower stem number and forag...

this study was conducted with the main purpose of investigating genetic variation among 13 selected sweetcherry (prunus avium cv. siah mashhad) genotypes, i.e., the most important iranian sweet cherry cultivars based on their pomological, morphological, and phonological characteristics. the experiment was laid out in a randomized complete block design with three replications at khorasan-e-razav...

BACKGROUND Vascular endothelial growth factor-A (VEGF-A) is intensively investigated in various medical fields. However, comparing VEGF-A measurements is difficult because sample acquisition and pre-analytic procedures differ between studies. We therefore investigated which variables act as confounders of VEGF-A measurements. METHODS Following a standardized protocol, blood was taken at three...

Administration of exogenous bovine ST (bST) increases growth rate, feed efficiency, and carcass quality in beef cattle. The magnitude of response to bST in beef cattle is variable and related to the age of the animal. Our objective was to determine the response of the somatotropic axis, in particular IGF-I, IGFBP-2, and IGFBP-3, to bST treatment from birth to 1 yr of age. Blood samples were col...
