The Wingless (Wg) protein is a secreted glycoprotein involved in intercellular signaling. On activation of the Wg signaling pathway, Armadillo is stabilized, causing target genes to be activated by the transcription factor Pangolin (Pan). This study investigated the roles of Pan in the developing wing of Drosophila by clonal analysis. Three different aspects of wing development were examined: c...
Spontaneous perirenal hemorrhage (SPH) is uncommon but can be a life-threatening condition which is associated with flank or abdominal pain and hypovolemia. The etiologies of SPH include tumor, vascular disease, and infection. Among the vascular diseases, polyarteritis nodosa (PAN) is common cause of the SPH. However, patients with PAN usually complain of nonspecific symptoms and the incidence ...
Chimpanzees' immediate responses to the death of a group-member have rarely been described. Exceptions include maternal care towards dead infants, and frenzied excitement and alarm following the sudden, traumatic deaths of older individuals [1-5]. Some wild chimpanzees die in their night nest [6], but the immediate effect this has on others is totally unknown. Here, with supporting video materi...
This paper describes a method for calibrating a pan-tilt camera head. The key feature of the method is that the camera, the pan-tilt unit, and the relationship between the camera and the pan-tilt unit, are calibrated independently. This paper develops a geometric model of the pan-tilt camera head and presents procedures to estimate the values of the unknown model parameters. Target image reposi...
We have analyzed anatomic variations in the pectoralis major and pectoralis minor muscles of common chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) and compared them to anatomic variations in these muscles in humans (Homo sapiens). We have macroscopically dissected these muscles in six adult Pan troglodytes, five Pan paniscus of ages ranging from fetus to adult, and five adult Homo sap...
Panchromatic (PAN) satellite imagery has been used successfully in different applications such as topographic mapping and terrain modelling. Nevertheless, PAN imagery is still one of the less used digital sources for land-change studies except few processes where the high-resolution of the PAN images is used to improve the visualization quality of the multi-spectral images. This research aimed ...
effect of seed priming on germination and seedling growth of sesame investigated under controlled conditions. the primed seeds with znso4 had the maximum germination percentage whereas the highest germination rate was observed in hydro-primed seeds. the treated seeds with peg showed the best growth of the seedlings and rootlet. the complementary field experiment was conducted to evaluate the ef...
Polyarteritis nodosa (PAN) is characterized by multisystem necrotizing vasculitis, primarily affecting small-to-medium-sized muscular arteries, and it is typically found in middle-aged men. PAN is rarely found in the female genital tract (including the uterus), and imaging of the uterus with PAN has not previously been reported. Reported is a case of a 78-year-old patient with uterus enlargemen...
مطالعه غشای آلیاژی پلی آکریلونیتریل ـ پلی سولفون و اثر نانو ذره های آلومینیوم اکسید برای جداسازی گاز
وجود برتری های فراوان سامانه های غشایی باعث گسترش استفاده از آن ها شده است. از غشا برای جداسازی گاز نیز استفاده می شود. در ایـن پـژوهش، بهبود ویژگی های جداسازی گاز در غشای آلیاژی پلیآکریلونیتریل (PAN)و پلیسولفون(PSF) با افزودن نـانو ذره های آلومینیوم اکسید مورد مطالعه قرار گرفته است. با افزودن پلـی سـولفون به غشای پلی آکریلونیتریل، بهترین ترکیب...
Cutting samples from evaporite deposits of Member Two of Gachsaran Formation in well #1 at Ab-Teymure Oil Field have been studied by petrographic microscope, SEM with EDX attachment and XRD to identify the halite crystal shapes. This study led to recognition of three stages, including flooding, concentration and desiccation, for the formation of halite in salt pan. In the flooding stage, the fl...
