Background: One of the most important causes of chronic liver disease is hepatitis C virus (HCV), which causes liver cirrhosis and hepatocellular carcinoma. To control the prevalence of the disease, knowledge and information in risk factor of HCV are required. The aim of this study was to compare the risk factors of infection between HCV patients with genotypes 1a and 3a. Methods: This is an o...

The development and improvement of electronic communication instruments and means in postmodern societies with fast intention has caused further multiplication in meanings and content of the communication itself. On the other hand the involvement of cyber space in our privacy has caused massive personality changes in people particularly the youth, In a way that individuals are separated from re...

To determine the T-cell receptor (TCR) V alpha/V beta gene usage of the human autologous gastric tumor-specific cytotoxic T-lymphocytes (CTLs), we first established two pairs of tumor cell lines, HST2 and SSTW, from the malignant peritoneal effusions of signet ring cell carcinomas and their peripheral blood lymphocyte-derived tumor-specific CD8-positive CTL lines, TcHST2 and TcSSTW. TCR V alpha...

abstract introduction: introduction: traditionally, the central library of any university is the main source of scientific data retrieval for respective faculty members. exploration of rate and pattern of such usage makes it possible to promote the quantity and quality of library services and increasing the efficacy of faculty members' activities. objective: to determine the rate of usage ...

The early post-operative course after hip arthroscopy for femoroacetabular impingement syndrome has not been thoroughly characterized or correlated to factors that may influence recovery. The aim of this study was to report on early pain, function and attitudes towards rehabilitation and to determine predictors of early recovery after hip arthroscopy. Sixty-two patients reported pre-operative p...

background: personal protection equipments (ppes) should be easily accessible to decrease contact with infecting factors and also should be used purposefully to effectively keep the health care personnel in a safe distance from the patient blood and body fluid which can easily infect the operating rooms personnel. this study aimed to find the operating rooms' personnel compliance with standards...

Mining operations and mineral-related industries are closely and directly related with the environment. The negative impacts of mining industry on the environment, known as environmental risks, must be controlled and managed in a way to minimize harmful and destructive effects. Environmental risk assessment studies are a suitable step to identify, analyze and rank the risk factors. In this stud...

Drugs are often used by women during pregnancy & lactstion. Midwives are among those giving service in maternal and child health programs, and are in contact with groups of pregnant & lactation women. In order to determine the midwives knowledge about drug usage in pregnancy and lactstion, this survey was carried out on all midwives of Kerman city ( n =69) in June 1995, using a questionnaire ba...

background: most of the amino acids are encoded by more than one codon, termed as synonymous codons. synonymous codon usage is not random as it is unique to species. in each amino acid family, some synonymous codons are preferred and this is referred to as synonymous codon usage bias (scub). trends associated with evolution of scub and factors influencing its diversification in plastomes of gen...

Chikungunya virus (CHIKV) is an arthropod-borne virus of the family Togaviridae that is transmitted to humans by Aedes spp. mosquitoes. Its genome comprises a 12 kb single-strand positive-sense RNA. In the present study, we report the patterns of synonymous codon usage in 141 CHIKV genomes by calculating several codon usage indices and applying multivariate statistical methods. Relative synonym...
