background: musculoskeletal disorders (msd) are concerned as costly health problems worldwide. rural people are more susceptible to musculoskeletal disorders. this study aimed to investigate the prevalence of musculoskeletal disorders and related factors among adult living in aq qalaian, iran. material and methods: this was a cross-sectional study which performed among 200 adult living in rural...

a recently described species of dysdercus, named dysdercus stehliki schaefer, 2013 (hemiptera: heteroptera: pyrrhocoridae), found in viçosa, minas gerais state, brazil, feeds upon the seeds of fallen fruits of sterculia chicha a. st. hil. (malvales: sterculiaceae). the biology and immature stages’ descriptions of d. stehliki were assessed in two environments: laboratory and field. individuals o...

nucleolar organizer regions (nor) are defined as nucleolar components containing a set of argyrophilic proteins which are selectively stained by colloidal silver nitrate staining. although studies have shown that the number of nor dots or particles is directly related to the rapidity of cell proliferation in cancer cells, prognostic or diagnostic value of nor remains controversial. the aim of t...

the problem of eye detection in face images is very important for a large number of applications ranging from face recognition to gaze tracking. in this paper we propose a new algorithm for eyes detection. first, the face region is extracted from the image by skin-color information. second, horizontal projection in image is used to approximate region of the eye be obtained . at last, the eye ce...

background: recently, we have shown that peroxisomal protein expression was induced upon retinoic acid treatment in mouse embryonic stem cells during the process of neurogenesis. thus, characterization of the respective promoter could elucidate the molecular aspects of transcriptional regulation of this gene. methods: using the conventional software programs for promoter prediction, a putative ...

this paper represents a new region-based active contour model that can be used to segment images with intensity non-uniformity and high level noise. the main idea of our proposed method is to use gaussian distributions with different means and variances with incorporation of intensity non-uniformity model for image segmentation. in order to integrate the spatial information between neighboring ...

Introduction: There are suspended fungal spores in the air and in the nasal mucosa of adults, especially in areas with a humid climate. Several studies have revealed the role of fungi in the pathogenesis of chronic rhinosinusitis (CRS) in recent years but it is a topic of controversy, especially in regions with low humidity. The aim of this study was to evaluate the prevalence of fungal specie...
