We consider the azimuthal angle dependence in the cross section of the hard leptoproduction of a photon on a nucleon target. We show that this dependence allows to define observables that isolate the twist-two and twist-three sectors in the deeply virtual Compton scattering amplitude. All twist-two and twist-three Compton form factors can be extracted from measurements of the charge odd part of...
Angiogenesis is a critical step in the growth and dissemination of malignant diseases, including pancreatic cancer. Twist has been shown to stimulate angiogenesis in the tumor site. However, whether Twist contributes to angiogenesis in pancreatic cancer remains unknown. In this paper, we found that the expression of Twist was significantly increased in human pancreatic cancer cell lines and pan...
800x600 background: pregnancy, due to hormonal changes and body reshaping, might disturb the pregnant women’s body image and self-esteem and also increase depression susceptibility. body dissatisfaction may result in some compensating attempts, such as weight loss, for improving body shape. these behaviors could result in serious outcomes for maternal and child health. the aim of the present st...
review studies are those researches in which the population under study consists of original articles in a defined field of human knowledge. the aim of the present review article is to overview such review studies and to determine the advantages and disadvantages of each study within the health domain. at the end of 2012 the pub med search engine was searched using “ systematic reviews ” and “ ...
background: previous studies on the correlation between dietary intakes and stroke have mostly focused on the dietary glycemic index (gi) of potatoes and there is no information regarding the correlation between potato consumption and risk of stroke. therefore, the aim of this study was to evaluate the correlation between potato consumption and risk of stroke in an iranian population. methods: ...
800x600 abstract: aim: the aim of this study was to investigate that the necessity of screening for celiac disease in idiopathic osteoporotic patients. background: osteopenia and osteoporosis are well-known and prevalent complications of celiac disease. however, the relative prevalence of celiac disease among osteoporotic populations is not known, and the benefit of screening for celiac disease...
Twist-three analysis of photon electroproduction off pion. Abstract We study twist-three effects in spin, charge, and azimuthal asymmetries in deeply virtual Compton scattering on a spin-zero target. Contributions which are power suppressed in 1/Q generate a new azimuthal angle dependence of the cross section which is not present in the leading twist results. On the other hand the leading twist...
Twist is a key transcription activator of epithelial-mesenchymal transition (EMT). It remains unclear how Twist induces gene expression. Here we report a mechanism by which Twist recruits BRD4 to direct WNT5A expression in basal-like breast cancer (BLBC). Twist contains a "histone H4-mimic" GK-X-GK motif that is diacetylated by Tip60. The diacetylated Twist binds the second bromodomain of BRD4,...
Twist is required in Drosophila embryogenesis for mesodermal specification and cell-fate choice. We have examined the role of Twist and Notch during adult indirect flight muscle development. Reduction in levels of Twist leads to abnormal myogenesis. Notch reduction causes a similar mutant phenotype and reduces Twist levels. Conversely, persistent expression, in myoblasts, of activated Notch cau...
