The Bicoid morphogen directs pattern formation along the anterior-posterior (A-P) axis of the Drosophila embryo. Bicoid is distributed in a concentration gradient that decreases exponentially from the anterior pole, however, it transcribes target genes such as hunchback in a step-function-like pattern; the expression domain is uniform and has a sharply defined posterior boundary. A 'gradient-af...
استفاده از سنجش از دور بخصوص در محدوده حرارتی به دلیل کاربرد های متعدد در علوم محیطی به طور روز افزون در حال افزایش می باشد. در حال حاضر دسترسی به داده های حرارتی با قدرت تفکیک مکانی و زمانی مناسب، محدودیت-های زیادی دارد. به همین دلیل در سال های اخیر روش های برای بهبود قدرت تفکیک مکانی این تصاویر با استفاده از تصاویر انعکاسی ارائه شده است. این تحقیق بر روی داده های سنجنده etm+و modis در بخش ها...
aim: injury from needle is one of the main ways of transmitting blood diseases in the medical staff. prevention and reduction of such diseases' side effects have been emphasized by the health ministry. this study aimed to investigate factors influencing the behavior of the elam city medical staff when working with sharps instruments. methods: in a cross-sectional study, using a census method, a...
Cellular fate of nanoparticles is vital to application of nanoparticles to cell imaging, bio-sensing, drug delivery, suppression of drug resistance, gene delivery, and cytotoxicity analysis. However, the current studies on cellular fate of nanoparticles have been controversial due to complications of interplay between many possible factors. By well-controlled experiments, we demonstrated unambi...
Background and Aim: Considering the increasing drug resistance to Aspergillus fumigatus, search for genes involved in its pathogenicity and identifying alternative antifungal drugs is of utmost importance. The aim of this study was to determine the effects of diclofenac sodium on the growth and sidB gene expression in Aspergillus fumigatus. Materials and Methods: In this study, Aspergillu...
The functional state of an organism is determined largely by the pattern of expression of its genes. The analysis of gene expression data from gene chips has primarily revolved around clustering and classi cation of the data using machine learning techniques based on the intensity of expression alone with the time-varying pattern mostly ignored. In this paper, we present a pattern recognition-b...
