Background: A direct relation exists between sodium and calcium excretion, but randomized studies evaluating the sustained effect of a low-salt diet on idiopathic hypercalciuria, one of the main risk factors for calcium-oxalate stone formation, are still lacking. Objective: Our goal was to evaluate the effect of a low-salt diet on urinary calcium excretion in patients affected by idiopathic cal...
در این پایان نامه پس از آوردن تعاریف مختصری از هندسه ریمان و هندسه فینسلر، در مورد متریک های داگلاس همراه با انحنای ایزوتروپیک لندزبرگ نسبی و انحنای ایزوتروپیک میانگین بروالد بحث می کنیم و سپس متریک های فینسلر را که دارای انحنای ایزوتروپیک بروالد هستند، معرفی می کنیم. ثابت می کنیم که بر روی مترهای داگلاس، دو مفهوم ایزوتروپیک بروالد بودن و ایزوتروپیک لندزبرگ نسبی بودن معادلند. لذا قضیه باکچو-مات...
Objective(s): Chronic myelogenous leukemia (CML) is a chronic myeloproliferative disorder characterized by the accumulation of myeloid cells with a chromosomal translocation known as the Philadelphia chromosome. In this study, we investigated the roles of miR-570 in CML development. Materials and Methods: Expression of miR-570 in CML samples and cell lines was determined by qRT-PCR. Glucose upt...
Stainless steel cladding is the formation of an alloy by creating a thin layer of stainless steel on another metal. In this research, a layer of SA240-TP316 austenitic stainless steel was coated on SA516-GR60 steel. Experiments were conducted to compare the mechanical properties of SA240-TP316 and claded SA516-GR60 steel welds in order to investigate the possibility of replacing the SA240-TP316...

Maternally expressed proteins function in vertebrates to establish the major body axes of the embryo and to establish a pre-pattern that sets the stage for later-acting zygotic signals. This pre-patterning drives the propensity of Xenopus animal cap cells to adopt neural fates under various experimental conditions. Previous studies found that the maternally expressed transcription factor, encod...
Aims: The aim of this study was to determine neuropsychological performance in apparently cognitively, mentally, and physically healthy abstinent alcohol-dependent subjects compared with control subjects who were recruited for a number of different neuroimaging studies. Methods: All subjects completed a battery of neuropsychological tests as part of the neuroimaging protocol. Results: The group...
MicroRNAs (miRs) are a class of small non-coding RNAs and have key roles in various cancer types. Recently, miR-503 has been reported to act as a tumor suppressor in osteosarcoma. However, the detailed mechanism of the regulatory role of miR-503 in osteosarcoma cell proliferation and invasion has largely remained elusive. The present study found that miR-503 was significantly downregulated in o...
