metal spinning as a kind of manufacturing process has capability to shape hollow components. in present work shear spinning process is used to formplates into conical shapes. moreover, the aim of this research is to demonstrate the impact of the process parameters (i.e. feeding rate and spindle speed) on wall thickness. this approachwas done by experimental and finite elements method. the resul...

Sambucus nigra (S.nigra) is used in the treatment of many diseases and disorders thanks to its antioxidant, anticarcinogenic, immunostimulating, antiallergic, antiviral, antibacterial properties. Ghrelin has anti-inflammatory effect on oxidative damage various organs cell types. The aim this study was immunohistochemically examine chymase, tryptase, ghrelin rat lung after S. administration. A t...

â â â  â â  â  abstract â  this paper examines the two most important current efforts to devise new rules binding all nations the negotiations in the wto of trade rules and the negotiations under the un framework convention on climate change to devise rules restricting the annual emissions of greenhouse gases. both negotiations have failed after several years of intensive effort. there are rema...

introduction:  clinical settings and teaching methods play a key role in students' learning. so, the present study aimed to investigates the effect of holding special training rounds on performance of pediatric residents. methods: this quasi-experimental study was conducted on 30 residents. they were randomly divided into two case (n=15) and control (n=15) groups. two groups received prete...

BACKGROUND Fine needle aspiration cytology (FNAC) forms one of the first diagnostic tools in the evaluation of tumors. Its role in diagnosing soft tissue tumors (STT) has been fairly documented, as well as debated. Present study was aimed at evaluating its scope in diagnosing 127 cases of soft tissue tumors. METHODS Conventional Pap and MGG staining was available in all the cases. Immunocytoc...

Objective-  In the present study we investigated the isolation protocol, population doubling time (PDT) and the expression of a pluripotential gene by RT-PCR analysis of early transcription factor Nanog in caprine umbilical cord (CUC) Wharton's jelly mesenchymal cells (WJMCs). Design- Experimental in vitro study.   Animals- Four mix breed goat.   Procedures- CUCs were collected from abattoi...
