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 frost as a harmful climatologic phenomenon affects various human activities and biological processes. due to mountainous nature of kurdistan province as the study area of this research in one hand and type and diversity of effective air masses on the other, the frequency, severity and duration of this phenomenon in the province are outstanding. confronting frost could be one of the...

Background & Aim: Medicinal plants, Since time immemorial, have been used in virtually all cultures as a source of medicine and ethnobotany has prevent to be a valuable method to find new herbal medicine and plant derived drugs. Material & Methods: This study determined medicinally important plants that are most frequently by the local inhabitants of Sistan to treat human diseases. In current ...

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...

Background: Embryonal carcinoma (EC) cells derived from germ cell tumors are valuable tools for investigating differentiation and developmental biology processes in vitro. The advantage of the reproducible and rapid expansion of these cell lines provides a useful alternative to embryos for the study of mammalian cell differentiation. During early stages of cell differentiation, the rate of tran...

The goal of medicine is to prevent harm as Hippocrates pointed out; “primum non nocere; first do no harm”. Has this fact been taken into account in developing Medical Education curricula in Asia? Frequency of diseases in Asia is different from high income countries (1, 2) and funds for research are lacking.  It is therefore important to allocate available funds to the most applicable issues to...
