Ten years after the identification of the first partial sequences of Torque teno virus (TTV), more than 200 full-length related genomes have been characterized in humans and in several animal species. As suspected in the earlier stages of their description, a considerable genetic variability characterizes TTV and related viruses, the current members of the floating genus Anellovirous. Since inf...
چکید ه سابقه و هدف ttv برای نخستین بار در سال 1997 در خون بیماران ژاپنی با سطوح بالای آلانین ترانسفراز( alt ) که عاری از دیگر ویروس های عامل هپاتیت بودند، کشف شد. به منظور تعیین فراوانی آلودگی به ttv و نقش آن در آسیب های کبدی، نمونه های سرمی افراد به ظاهر سالم و افراد آلوده به ویروس های hbv و hcv از سازمان انتقال خون شهر تبریز تهیه گردید و مورد آزمایش قرار گرفت. مواد وروش ها مطالعه انجا...

Target Audience Clinicians and researchers who wish to improve the detection and diagnosis accuracy of brain tumor or cerebral disease using MR perfusion. Introduction 4-D dynamic susceptibility contrast (DSC) magnetic resonance imaging (MRI) is a well-established perfusion technique for non-invasive characterization of tissue dynamics, with promising applications in assessing a wide range of d...
Transit Timing Variation (TTV) of hot Jupiters provides direct observational evidence planet tidal dissipation. Detecting dissipation through TTV needs high precision transit timings and long timing baselines. In this work, we predict discuss the potential scientific contribution SiTian Survey in detecting analyzing exoplanet TTV. We develop a detection pipeline for that aims at time-domain ast...
ABSTRACT We present 17 transit light curves of seven known warm-Jupiters observed with the CHaracterising ExOPlanet Satellite (CHEOPS). The have been collected as part CHEOPS Guaranteed Time Observation (GTO) program that searches for transit-timing variation (TTV) induced by a possible external perturber to shed on evolution path such planetary systems. describe observation process, from plann...
The new approach using Fixed Abrasive (FA) pads for polishing thick film Silicon-onInsulator (SOI) wafers after bonding and grinding process [1] has been further developed. The aim is a practicable industrial manufacturing process, where the major specifications especially in long term stability and removal rate should be achieved. In base line studies a stable removal rate on suitable level ha...
RATIONALE Idiopathic pulmonary fibrosis is a progressive, uniformly fatal interstitial lung disease. An acute exacerbation of idiopathic pulmonary fibrosis is an episode of acute respiratory worsening without an identifiable etiology. Occult viral infection has been proposed as a possible cause of acute exacerbation. OBJECTIVES To use unbiased genomics-based discovery methods to define the ro...
BACKGROUND Intubating laryngeal mask airways (LMAs) such as i-gel and Aura-i could serve as rescue devices in resuscitation and further ensure the airway by facilitating trachea intubation without ventilation interruption. But data regarding intubating LMAs in novice are limited and skill degeneration without regular training has not been evaluated. So we designed this prospective randomized cr...
