زمینه و هدف: ویروس hgv عضو خانواده فلاوی ویریده و دارای ژنوم rna می باشد و از نظر شباهت ترادف های نوکلئوتیدی و اسید آمینه ای به hcv شباهت زیادی دارد. این ویروس به دلیل توانایی درگیری لنفوسیت ها برای طولانی مدت این امکان را داشته تا در ایجاد و یا پیچیده کردن عوارض بالینی مبتلایان به سرطان خون نقش داشته باشند؛ بنابراین در این مطالعه میزان شیوع عفونت ویروس های hbv، hgv و hcv در مبتلایان به سرطان ه...
INTRODUCTION With higher gradient strength and slew rate, local gradient coils such as planar insert gradients can attain higher spatial and temporal resolution than the body gradients. Many imaging tasks, such as dynamic contrast enhanced (DCE) MRI for breast lesion characterization, can benefit from high spatial and temporal resolution. However, the homogeneous gradient volume (HGV) of the pl...
SUMMARY The risk of transfusion-transmitted infections has been greatly reduced by improvements in donor screening and testing. However, newly recognized blood-borne infectious agents can be threats to blood safety. In order to evaluate the prevalence some of these agents in blood donors, a systematic review was conducted. Data were obtained from published papers related to HGV, Torque Teno vir...
زمینه: عفونت ویروس های ایجاد کننده هپاتیت به دلیل پتانسیل ایجاد عفونت های حاد و مزمن در لکوسیت های خونی و به خصوص لنفوسیتها یکی از علل احتمالی چالش برانگیز در بیماران مبتلا به انواع سرطان های خون محسوب می گردند. امروزه از میان ویروسهای مختلف ایجادکننده هپاتیت ویروسیhgv به دلیل مکانیسم ناشناخته پاتوژنز در روند بروز و یا تشدید بدخیمی های خونی از جایگاه ویژه ای برخوردار شده است. در این تحقیق به ...
conclusions overall, 4.3% of patients had positive results for gbv-c/hgv and all negative for hiv, hcv and hbv. further studies are needed to elucidate real prevalence, risk factors and characteristics of hgv infection in iranian hemodialysis patients. results in total, 81 males and 57 females were included. the mean age of patients was 62.16 ± 14.86 years. six (4.3%) had positive results for g...
The trajectory prediction of the hypersonic glide vehicle (HGV) can provide hit point information for early warning systems, which is great significance near-space defence operations. However, heavy-tailed noise caused by abnormal environmental disturbance and abrupt changes in seriously affects accuracy HGV prediction. To solve problem under noise, we propose an adaptive multivariate Student's...
The native UK vehicle fleet is right hand drive (RHD) with a corresponding road infrastructure, presenting unique challenges to the increasing numbers of mainland European left hand drive (LHD) heavy goods vehicles (HGVs) using UK roads. This paper analyses the nature and circumstances of HGV accidents in the UK, paying particular attention to LHD HGVs and the causal factors exhibited. Using in...
In order to defend the hypersonic glide vehicle (HGV), a cost-effective single-model tracking algorithm using Cubature Kalman filter (CKF) is proposed in this paper based on modified aerodynamic model (MAM) as process equation and radar measurement model as measurement equation. In the existing aerodynamic model, the two control variables attack angle and bank angle cannot be measured by the ex...
PCR is, to date, the only available tool for the detection of GB virus C (GBV-C) and hepatitis G virus (HGV) RNAs. Twenty-two French laboratories participated in a quality control study to assess the sensitivity and specificity of their procedures. The panel included 13 positive controls and 7 negative controls. The laboratories used either in-house PCR techniques adapted from the literature or...
China held the first of what could be a series of tests to check on the speed of its new experimental hypersonic glide vehicle (HGV) which would approach its target at a velocity of up to 10 times the speed of sound. Basically dubbed as WU-14 by Pentagon, this development interpreted to be designed for mounting on intercontinental ballistic missiles, as when the hypersonic vehicle is detached f...
