glutathione s-transferases (gsts) are members of multigenic family which have the essential functionin cells as an antioxidant. in the present study we studied the polymorphism of gstt1 and gstm1 deletion genotypes in iranian patients with primary closed angle glaucoma (pcag) compared to healthy subjects. we conducted a study of 41 pcag patients (24 women, 17 men) and 100 healthy participants (...

In this paper, the notions of anti-reflexive kernel, symmetric kernel, reflexive closure, and symmetric closure of a soft set relation are first introduced, respectively. Then, their accurate calculation formulae and some properties are obtained. Finally, soft set relation mappings and inverse soft set relationmappings are proposed, and some related properties are discussed. © 2010 Elsevier Ltd...

In this paper, we introduce the concept of linear v{C}ech closure spaces and establish the properties of open sets in linear v{C}ech closure spaces (Lv{C}CS). Here, we observe that the concept of linearity is preserved by semi-open sets, g-semi open sets, $gamma$-open sets, sgc-dense sets and compact sets in Lv{C}CS. We also discuss the concept of relative v{C}ech closure operator, meet and pro...

The objective of this paper is to investigate the effect two typical supercavity flow patterns (double-cavity and wake-closure) on ventilated geometry supercavitating structure further reveal different mechanisms gas leakage for these patterns. An inhomogeneous multiphase model with shear stress transport turbulence was employed validate investigation by experimental results. investigated quant...

An isothermal endoreversible chemical engine operating between a finite high-chemicalpotential reservoir and an infinite low-chemicalpotential reservoir in which the mass transfer between the working fluid and the mass reservoirs obeys the linear mass-transfer law [g ∝ ∆μ], is put forward in this paper. Optimal control theory is applied to determine the optimal cycle configuration corresponding...

Bouveret's syndrome involves gastric outlet obstruction by gallstone. Herein we describe an unusual case of duodenal bulb obstruction by gallstone. An 80-year-old woman was hospitalized with a fifteen-day history of vomiting. Computed tomography (CT) showed pneumobilia and a round calcified mass in the second portion of the duodenum. Upper gastrointestinal tract series demonstrated the same siz...
