Abstract
BACKGROUND Non-small cell lung cancer (NSCLC) patients with COVID-19 have an excessive chance of morbidity and mortality. The fecal-nasopharyngeal microbiota compositions of NSCLC patients were assessed in this study. METHODS In total, 234 samples were collected from 17 NSCLC patients infected with COVID-19, 20 NSCLC patients without confirmed COVID-19, 40 non NSCLC patients with COVID-19, and 40 healthy individuals. RESULTS In lung microbiota, the abundance of Streptococcus spp. in NSCLC patients with confirmed COVID-19 was significantly higher than the two control groups. Pseudomonas aeruginosa and Staphylococcus aureus were listed as the most frequent pulmonary bacterial groups that colonized COVID-19 patients. In fecal specimens, the numbers of Bacteroidetes, Firmicutes, and Actinobacteria phyla were significantly higher amongst NSCLC patients with COVID-19. NSCLC patients infected with COVID-19 showed lower levels of Lactobacillus spp., Akkermansia muciniphila, and Bifidobacterium spp. The counts of Streptococcus spp., in NSCLC patients with COVID-19 were significantly higher than those of healthy individuals (8.49±0.70 log CFU/g wet feces vs 8.49±0.70 log CFU/g wet feces). Prevotella spp. were enriched in the gut and respiratory tracts of COVID-19 patient groups. The unbiased analysis showed an increment in Enterococcus spp., Streptococcus spp., and Prevotella spp. CONCLUSION Eventually, it was found that compared to control groups, COVID-19 patients with NSCLC showed diminished gut bacteria diversity and increase in Lactobacillus spp., A. muciniphila, and Bifidobacterium spp. The overgrowth of Enterococcus spp., Streptococcus spp., and Prevotella spp. could be potential predictive biomarkers in the gut-lung axis of NSCLC patients with COVID-19.

Abstract
During replication, some mutations occur in SARS-CoV-2, the causal agent of COVID-19, leading to the emergence of different variants of the virus. The mutations that accrue in different variants of the virus, influence the virus' ability to bind to human cell receptors and ability to evade the human immune system, the rate of viral transmission, and effectiveness of vaccines. Some of these mutations occur in the receptor binding domain (RBD) of the spike protein that may change the affinity of the virus for the ACE2 receptor. In this study, several in silico techniques, such as MD and SMD simulations, were used to perform comparative studies to deeply understand the effect of mutation on structural and functional details of the interaction of the spike glycoprotein of SARS-CoV-2, with the ACE2 receptor. According to our results, the mutation in the RBD associated with the Omicron variant increase binding affinity of the virus to ACE2 when compared to wild type and Delta variants. We also observed that the flexibility of the spike protein of the Omicron variant was lower than in comparison to other variants. In summary, different mutations in variants of the virus can have an effect on the binding mechanism of the receptor binding domain of the virus with ACE2.

Abstract
BACKGROUND Although meningitis is largely preventable, it still causes hundreds of thousands of deaths globally each year. WHO set ambitious goals to reduce meningitis cases by 2030, and assessing trends in the global meningitis burden can help track progress and identify gaps in achieving these goals. Using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we aimed to assess incident cases and deaths due to acute infectious meningitis by aetiology and age from 1990 to 2019, for 204 countries and territories. METHODS We modelled meningitis mortality using vital registration, verbal autopsy, sample-based vital registration, and mortality surveillance data. Meningitis morbidity was modelled with a Bayesian compartmental model, using data from the published literature identified by a systematic review, as well as surveillance data, inpatient hospital admissions, health insurance claims, and cause-specific meningitis mortality estimates. For aetiology estimation, data from multiple causes of death, vital registration, hospital discharge, microbial laboratory, and literature studies were analysed by use of a network analysis model to estimate the proportion of meningitis deaths and cases attributable to the following aetiologies: Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae, group B Streptococcus, Escherichia coli, Klebsiella pneumoniae, Listeria monocytogenes, Staphylococcus aureus, viruses, and a residual other pathogen category. FINDINGS In 2019, there were an estimated 236 000 deaths (95% uncertainty interval [UI] 204 000-277 000) and 2·51 million (2·11-2·99) incident cases due to meningitis globally. The burden was greatest in children younger than 5 years, with 112 000 deaths (87 400-145 000) and 1·28 million incident cases (0·947-1·71) in 2019. Age-standardised mortality rates decreased from 7·5 (6·6-8·4) per 100 000 population in 1990 to 3·3 (2·8-3·9) per 100 000 population in 2019. The highest proportion of total all-age meningitis deaths in 2019 was attributable to S pneumoniae (18·1% [17·1-19·2]), followed by N meningitidis (13·6% [12·7-14·4]) and K pneumoniae (12·2% [10·2-14·3]). Between 1990 and 2019, H influenzae showed the largest reduction in the number of deaths among children younger than 5 years (76·5% [69·5-81·8]), followed by N meningitidis (72·3% [64·4-78·5]) and viruses (58·2% [47·1-67·3]). INTERPRETATION Substantial progress has been made in reducing meningitis mortality over the past three decades. However, more meningitis-related deaths might be prevented by quickly scaling up immunisation and expanding access to health services. Further reduction in the global meningitis burden should be possible through low-cost multivalent vaccines, increased access to accurate and rapid diagnostic assays, enhanced surveillance, and early treatment.

Abstract
Background One of the most prominent global health threats is antibiotic resistance, leading to infection treatment failure. The first Iranian antibiotic awareness week campaign was initiated to improve the prudent use and wise prescription of antibiotics. Materials and Methods The Isfahan antibiotic awareness campaign was held from November 30 to December 6, 2019, among two targeted populations; the general population and health-care workers by Isfahan University of Medical Sciences. In this campaign held in the main squares, streets, and a city's referral hospital, various educational methods were used to aware and sensitize the general population and medical staff about antibiotics and microbial resistance. These methods include face-to-face training, brochures, advertisement posters and billboards around the city, educational videos, social media messages, retraining for medical doctors and medical specialists, and interviewing in the Islamic Republic of Iran Broadcast. Results Two hundred and twenty general practitioners, medical specialists, and residents participated in two retraining educational conferences in Al-Zahra Hospital, Isfahan, Iran. The mean score satisfaction of the two conferences was three from four. Nearly 2000 of the general population were under face-to-face educational programs whom after that, 83.6% had the correct answer to the questions around antimicrobial awareness. Conclusions This campaign was an excellent experience as a pilot study with appealing issues. Further, activities are required to improve engagement with the target population and determine the impact of this campaign on antibiotic consumption and prescription behavior among the public and health-care professionals.

Abstract
Background and objectives: Up to present no efficacious antiviral medications have been discovered in order to eradicate SARS-CoV-2 in nasopharyngeal tract. In this article, the aim is to evaluate the effectiveness of a new herbal drug product called Aftogel patch, which contains licorice extract, in the eradication of this novel coronavirus in the nasopharyngeal secretions of the patients. Methods: In this triple-blind randomized clinical trial, 125 patients with positive real-time PCR for SARS-CoV-2 and in stage 0 and/or 1 of COVID-19 were studied in two separate groups, namely interventional and placebo, in which they used Aftogel and placebo patches, respectively. At the end of the study, the results of PCR test in aforementioned groups were assessed and compared. Results: Following the application of Aftogel, Real-time PCR was converted to negative in 53.97% of patients which was significantly higher than that of the placebo groups. (27.40%, P= 0.003). Conclusion: It seems that Aftogel mucoadhesive patch (Licorice extract) is effective in the eradication of SARS-CoV-2 which has colonized the nasopharyngeal area. Hence, this drug product has the potential for evaluation as a prophylactic agent against COVID-19.

Abstract
OBJECTIVE Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the novel coronavirus causing severe respiratory illness (COVID-19). This virus was initially identified in Wuhan city, a populated area of the Hubei province in China, and still remains one of the major global health challenges. RNA interference (RNAi) is a mechanism of post-transcriptional gene silencing that plays a crucial role in innate viral defense mechanisms by inhibiting the virus replication as well as expression of various viral proteins. Dicer, Drosha, Ago2, and DGCR8 are essential components of the RNAi system, which is supposed to be dysregulated in COVID-19 patients. This study aimed to assess the expression level of the mentioned mRNAs in COVID-19patients compared to healthy individuals. RESULTS Our findings demonstrated that the expression of Dicer, Drosha, and Ago2 was statistically altered in COVID-19 patients compared to healthy subjects. Ultimately, the RNA interference mechanism as a crucial antiviral defense system was suggested to be dysregulated in COVID-19 patients.

Abstract
COVID-19 is still a deadly disease that remains yet a major challenge for humans. In recent times, many large pharmaceutical and non-pharmaceutical companies have invested a lot of time and cost in fighting this disease. In this regard, today's scientific knowledge shows that designing and producing an effective vaccine is the best possible way to diminish the disease burden and dissemination or even eradicate the disease. Due to the urgent need, many vaccines are now available earlier than scheduled. New technologies have also helped to produce much more effective vaccines, although the potential side effects must be taken into account. Thus, in this review, the types of vaccines and vaccine designs made against COVID-19, the vaccination programs, as well as the delivery methods and molecules that have been used to deliver some vaccines that need a carrier will be described.

Abstract
For the first time, an aqueous extract of Melilotus officinalis was used to synthesize bimetallic silver selenide chalcogenide nanostructures (Ag2Se-NCs). The formation of NCs was confirmed and characterized by UV-visible and FTIR spectroscopy, SEM and TEM imaging, XRD and EDX crystallography, zeta potential (ZP) and size distribution (DLS). The bioactivities of biosynthesized Ag2Se-NCs, such as antibacterial, antibiofilm, antioxidant and cytotoxicity potentials, were then examined. Bio-based Ag2Se-NCs were successfully synthesized with mostly spherical shape in the size range of 20-40 nm. Additionally, the MIC and MBC values of Ag2Se-NCs against β-lactam-resistant Pseudomonas aeruginosa (ATCC 27853) were 3.12 and 50 µg/ml, respectively. The DPPH scavenging potential of Ag2Se-NCs in terms of IC50 was estimated to be 58.52. Green-synthesized Ag2Se-NCs have been shown to have promising benefits and could be used for biomedical applications. Although the findings indicate promising bioactivity of Ag2Se-NCs synthesized by M. officinalis extract (MO), more studies are required to clarify the comprehensive mechanistic biological activities.

Abstract
Coronavirus disease-19 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The SARS-CoV-2 virus strains has geographical diversity associated with diverse severity, mortality rate, and response to treatment that were characterized using phylogenetic network analysis of SARS-CoV-2 genomes. Although, there is no explicit and integrative explanation for these variations, the genetic arrangement, and stability of SARS-CoV-2 are basic contributing factors to its virulence and pathogenesis. Hence, understanding these features can be used to predict the future transmission dynamics of SARS-CoV-2 infection, drug development, and vaccine. In this review, we discuss the most recent findings on the mutations in the SARS-CoV-2, which provide valuable information on the genetic diversity of SARS-CoV-2, especially for DNA-based diagnosis, antivirals, and vaccine development for COVID-19.

Abstract
INTRODUCTION The aim of the present study was to show the effect of public health educational campaign regarding antibiotic use and microbial resistance on knowledge, attitude, and practice of people in Isfahan. MATERIALS AND METHODS This quasi-experimental study was conducted in October 2019 on the public population in Isfahan (a city in the center of Iran). Simple random sampling was done in ten urban areas.). A total of 708 people participated in the study. For assessing the knowledge, attitude, and practice a related researchers-made questionnaire was used in the present study. Finally, data were entered into SPSS (20) and analytical statistics including paired t-test were used. The statistical significance level was considered <0.05. RESULTS The majority of participants in this study were female 434 (61.9%) and the rest of them were male. The mean ± standard deviation of age was 31.68 (11.11), range of 11-67. More than 50 present of participants had a Bachelor's degree (37.7%) and diploma (27.7%). Most individuals were self-employed 277 (43.1%). About the type of marriage, 54.89% were single and others were married. Results showed that the mean of knowledge and attitude was increased after the intervention (P < 0.05). CONCLUSION Increase knowledge between people, adherence to treatment and minimizes healthcare costs, however, "antibiotics are misused so often because of the belief that these are benign drugs. In the absence of urgent corrective and protective actions, the world is heading towards a postantibiotic era, in which many common infections will no longer have a cure and once again, kill unabated.

Abstract
Colorectal cancer (CRC) is the fourth most common cause of cancer and mortality worldwide and is the third most common cancer in men and women. Surgery, radiotherapy, and chemotherapy are conventionally used for the treatment of colorectal cancer. However, these methods are associated with various side effects on normal cells. Thus, new studies are moving towards more effective and non-invasive methods for treatment of colorectal cancer. Targeted therapy of CRC is a promising new approach to enhance the efficiency and decrease the toxicity of the treatment. In targeted therapy of CRC, antibody fragments can directly inhibit tumor cell growth and proliferation. They also can act as an ideal carrier for targeted delivery of anticancer drugs. In the present study, the structure and function of different formats of antibody fragments, immune-targeted therapy of CRC using antibody fragments will be discussed.

Abstract
Due to the vastness of the science virology, it is no longer an offshoot solely of the microbiology. Viruses have become as the causative agents of major epidemics throughout history. Many therapeutic strategies have been used for these microorganisms, and in this way the recognizing of potential targets of viruses is of particular importance for success. For decades, antibodies and antibody fragments have occupied a significant body of the treatment approaches against infectious diseases. Because of their high affinity, they can be designed and engineered against a variety of purposes, mainly since antibody fragments such as scFv, nanobody, diabody, and bispecific antibody have emerged owing to their small size and interesting properties. In this review, we have discussed the antibody discovery and molecular and biological design of antibody fragments as inspiring therapeutic and diagnostic agents against viral targets.

Abstract
Gastrointestinal (GI) disorders including a wide range of infectious, inflammatory, autoimmune, etc. disorders. Inflammatory bowel and celiac disease are non-fatal but overwhelming GI associated disorders. IBD and celiac's complications, besides the great suffering, disturb the normal life of the patients and make them involved in mental and physical problems. The emerging role of genetic content is deniable for GI inflammatory disorders incidence, and long non-coding RNAs (lncRNAs) function is the recent topic for its association. Analyzing of absolute lncRNAs interference in GI inflammatory appearance remains in infancy, and more studies are requested. Here, we concisely performed a systematic review in the last knowledge up to 2020 to identify all of the significant lncRNAs associated with the initiation and progression of GI inflammatory diseases. Accordingly, this assay attempted to refer to the expression of lncRNAs changing from the normal state, discovery of genetic mechanisms, and main effectors that would trigger associated IBD and celiac expression and immune responses would be effective for therapeutic approaches. It could be useful for prognostic and diagnostic purposes of GI associated inflammatory disorders.

Abstract
Background: The use of gold nanoparticles in medicine and especially in cancer treatment has been of interest to researchers. The effectiveness of this nanoparticle on cells significantly depends on the amount of its entry into the cells. This study was performed to compare the rate and mechanism of effect of gold nanoparticles coated with different amino acid on PC12 cancer cell line. Materials and Methods: The PC12 cells line were exposed to various concentrations of amino acid coated and uncoated gold nanoparticles (0.5, 2.5 and 5 μM). Cell death rate was determined according to level of Lactate dehydrogenase (LDH) release from cells and MTT assay. In addition cell morphology and the amount of Cellular Reactive oxygen species (ROS) were studied. Results: The uncoated gold nanoparticles have shown minor effects on cellular life. Gold nanoparticles coated by tryptophan at high concentrations (2.5, 5 and 25μM) increase in cancer cells metabolic activity. Gold nanoparticles coated by Aspartate also produce the largest amount of LDH and ROS in cancer cells and therefore caused of highest rate of apoptosis. Conclusion: The results showed that the nanoparticles coated with amino acids are affected on cellular metabolism and apoptosis more than uncoated nanoparticles. Also the smallest coated nanoparticles (coated by aspartate) have the most influence and by increasing the size, this effect was reduced.

Abstract
GB Virus C (GBV-C) and Hepatitis C Virus (HCV) belong to the Flaviviridae family of viruses and GBV-C is the closest virus to HCV genetically. Possibility of interaction between HCV and GBV-C and its association with other liver diseases are the most important clinical aspects which encourage researchers to develop a technique for detection of these viruses simultaneously. In this study a SYBR Green multiplex real time RT-PCR technique as a new economical and sensitive method was optimized for simultaneous detection of HCV/ GBV-C in cirrhotic patients. After designing two pairs of specific primers for HCV and GBV-C, SYBR Green Real time RT-PCR technique optimization was performed separately for each virus. Then, multiplex PCR was developed. Finally the optimized technique was performed on positive and negative plasma samples. Eighty nine cirrhotic HCV positive plasma samples (29 of genotype 3a and 27 of genotype 1a) were collected from patients before receiving treatment. 14% of genotype 3a and 17.1% of genotype 1a showed HCV/ GBV-C co-infection. As a result, 13.48% of 89 samples had HCV/ GBV-C co-infection that was compatible with other results from all over the world. Data showed no apparent influence of HGV co-infection on the either clinical or virological aspect of HCV infection. Furthermore, with application of multiplex Real time RT-PCR technique, more time and cost could be saved in clinical-research settings.

Abstract
Hepatitis C disease is a virus mediated infection causing major health problem worldwide. Conversions of immune surveillance play an important role in response to virus clearance. Immune modulating molecules such as HLA-G and IL-10 that convert immune response toward Th2 may play a role to inhibit response from combined therapy with IFN-α2α and ribavirin. The objective of this study was to investigate the expression of HLA-G and IL-10 in responder and non-responder HCV positive patients. In this study, characteristics of the virus and 48 responder and non-responder patients in response to the combined therapy with IFN-α2α and ribavirin were analyzed. The expression levels of HLA-G and IL-10 were conducted using real-time PCR. Also, soluble HLA-G in both groups of patients and healthy individuals were determined by enzyme-linked immunosorbent assay. According to the obtained data, HCV 1a was the predominant genotype in responder and non-responder patients. Expression levels of HLA-G and IL-10 in non-responder group was significantly more than responder and control groups (P<0.001). Additionally, expression levels of HLA-G and IL-10 were remarkably higher compared to healthy individuals at the beginning of treatment. Soluble HLA-G in non-responder patients was noticeably increased in comparison to responder patients after treatment (P<0.05). These findings suggest that elevation of HLA-G and IL-10 in HCV infected patients may play an important role in response to combined therapy with IFN-α2α and ribavirin.

Abstract
Hepatitis C Virus is one of the main reasons for chronic liver disease and hepatocellular carcinoma. Combination therapy with Interferon (peg-IFN-α) and Ribavirin (RBV) clear the virus more likely than the others. Different factors like virus and host characteristics influence on response to treatment. The most important viral factors include virus genotype and viral load; host factors like genetic, gender, race, age, weight and liver enzymes are also important. Previous studies have shown that single nucleotide polymorphisms (SNPs) in IFNR genes can regulate and influence on treatment with IFN. The purpose of this study is to investigate the association between SNPs in IFN-α receptor (IFNAR1 & IFNAR2) genes among subjects affected with chronic hepatitis C, who have treated with IFN and RBV, and also relationship between HCV genotypes and response to combination antiviral therapy. Peripheral blood mononuclear cells (PBMCs) were taken from whole blood of 61 patients affected with chronic hepatitis C who were treated with IFN and Ribavirin. Then, DNA was extracted from PBMCs and quality of DNA was assessed with Nanodrop finally two SNPs [Ex4-30G>C] and [Ivs1-4640 G>A] of IFN receptor genes (IFNAR1 and IFNAR2) were measured by TaqMan Real-Time PCR in ABi Prism 7900 system. Also to confirm the response rate to therapy, RNA was extracted then RT PCR was performed and final product was studied with gel electrophoresis and UV spectroscopy. Statistical analysis was performed using SPSS version 18.0 for Windows. The analysis of results from TaqMan SNP Genotyping has been shown that two SNPs (Ex4-30G>C and Ivs1-4640 G>A) of IFNAR1 and IFNAR2 didn't show any relationship with response to combined therapy in subjects affected with chronic hepatitis C who have treated with peg-IFN-α and Ribavirin. 61 patients complete the treatment period. 54 patients (%88/5) of them responded to treatment and 7 patients (%11/5) did not. Research and data analysis have shown that there is no significant relationship between sex (P=0 /7) and age (P=0 /2). But there is a relationship between genotype-3a and response to combined therapy of IFN-α and RBV (0/02). Studies have shown that gene polymorphisms in IVSS1-22G location of IFNAR1 gene had a relationship with IFN treatment response. But current study has shown that there is no significant relationship between two SNPs Ex4-30G>C and Ivs1-4640 G>A and response to IFN therapy. In continue we suggest that it would be better to use this technique to evaluate other SNPs in IFN genes.

Abstract
BACKGROUND We intend to design and validate a low-cost assay for the detection of hepatitis C virus (HCV) RNA using rapid-cycle RT-PCR. The procedure is performed in a closed system with little risk of contamination allowing PCR and product identification to be performed within one or two hours. METHODS A SYBR Green-based real-time RT-PCR for rapid detection of HCV. Amplicon synthesis was monitored continuously by SYBR Green I, which binds to double stranded DNA during PCR. The PCR products were identified by melting curve analysis. Standard sera with known concentrations of HCV RNA and 150 clinical samples were used to validate our assay. RESULTS The minimum detection level of our assay was less than 50 IU/mL. The results on 100 plasma samples were comparable with commercial assays. CONCLUSIONS This method is useful for rapid qualitative detection of HCV infection and particularly suitable for routine diagnostic applications.

Abstract
BACKGROUND Chronic hepatitis C (CHC) is a major contributor to cirrhosis and hepatocellular carcinoma and major global public health problem that causes mortality in both developed and developing countries.For the past decade, treatment with pegylated interferon (peg interferon α) and ribavirin (RBV) has been associated with rates of sustained virologic response of ≤ 66% among patients with hepatitis C virus (HCV) infection. In this study, we report the response rate of Iranian treatment-naïve CHC patients to Pegaferon, a locally developed pegylated interferon-α2a (PEG-IFNα2a). METHODS Patients diagnosed with CHC who referred to two university based outpatient clinics in Tehran from December 2007 to May 2011 were enrolled in a single-group, open-labeled experimental design. Eligible patients were above 15 years of age and had HCV infection with evidence of chronic hepatitis. Exclusion criteria included the presence of a debilitating disease, decompensated cirrhosis or refusal to participate in the study. Patients were treated with 180μg Pegaferon weekly in addition to 800-1200 mg daily, weight-based RBV for 24 or 48 weeks depending on genotype. Viral response and adverse effects were recorded. RESULTS A total of 216 patients were enrolled in the study of which 83.3% were male and 16.7% were female. In 93 (43.1%) patients, the HCV RNA viral load was ≥ 800,000 IU/ml before starting treatment. "As-treated analysis" indicated that a total of 168 (77.8%) patients achieved sustained viral response (SVR, undetectable plasma HCV RNA 24 weeks after the last planned dose of study treatment). CONCLUSION This study, with a larger number of participants, confirms the results of a previous study by the authors that Pegaferon, a PEG-IFNα 2a locally produced in Iran, is effective in treatment-naïve CHC patients.

Abstract
BACKGROUND To evaluate the safety and effectiveness of locally produced pegylated interferon-alpha2a in treatment-naïve patients with chronic hepatitis C. METHODS All treatment-naïve patients diagnosed with chronic hepatitis C who referred to two university based outpatient clinics in Tehran from December 2007 to May 2008 were enrolled. Exclusion criteria included the presence of a debilitating disease, decompensated cirrhosis, or refusal to participate in the study. Patients were treated with 180 microg pegylated interferon-alpha2a (Pegaferon) weekly and 800 - 1200 mg ribavirin daily for 24 or 48 weeks depending on genotype and weight. Viral and biochemical response and adverse drug reactions were recorded. RESULTS A total of 108 patients were enrolled; 63 with genotype 1 and 45 with genotypes 2 and 3. The mean age of the patients was 39 years (range: 19 - 65). Ninety-seven patients completed the study and 76 achieved sustained viral response. The sustained viral response among patients completing the study was 67% for genotype 1 and 95% for genotypes 2 and 3. Adverse events were well tolerated and none led to discontinuation of treatment, however dose adjustment was necessitated in 16 patients. The most common adverse events were fatigue (73.5%), poor appetite (66.2%), and feverishness (57.4%). The mean hemoglobin drop was 2.9 g/dL. CONCLUSION Locally produced PEG-IFN in Iran is safe and effective in treatment-naïve chronic hepatitis C.

Abstract
BACKGROUND It is necessary to develop a highly specific and sensitive assay to quantify the exact amount of hepatitis C virus (HCV) RNA in blood of patients with hepatitis C. For this reason, a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay for quantification of HCV RNA in human plasma was developed. METHODS A pair of primers as well as hybridization probes were selected. A real-time RT-PCR was set up and optimized. To establish the sensitivity of the assay, a serial dilution of HCV standards and reference sera, including the six major HCV genotypes, was used. The performance of the assay was evaluated with 191 known HCV-RNA positive and 100 negative samples. RESULTS The real-time assay had a sensitivity of 50 IU/mL, with a dynamic range of detection between 10(3) and 10(6) IU/mL. The coefficients of variation of threshold cycle values in intra- and inter-day-runs were <1.77% and 3.40%, respectively. Measurement of HCV-RNA positive samples yielded reproducible data with 100% specificity. CONCLUSIONS The high sensitivity, simplicity, reproducibility, wide dynamic range, and low cost of this real-time HCV RNA quantification makes this method especially suitable for monitoring viral load during therapy and tailoring of treatment schedules accordingly.

Abstract
BACKGROUND Cholesterol oxidase (CHO) has various clinical and industrial applications. Recently, microbial CHO have received a great attention for their wide usage in medicine. Here, taxonomic characterizations of isolated strain from soil, optimization of the conditions for CHO production and biochemical characterizations of produced CHO enzyme were described. Finally, CHO gene was cloned into a cloning vector. METHODS Various samples were collected and cultivated in a screening medium consisting of cholesterol. For isolation of CHO-producing bacteria, well-grown colonies were inoculated into an optimized medium. Different biochemical and microbiological tests were performed on isolated bacteria to identify their properties. For phylogenic analysis, a partial sequence of l6s rRNA was amplified by PCR using universally conserved primers. A modified method was applied for determination of CHO activity. Then, extracellular CHO activity was assessed under different temperature, pH and cholesterol concentration conditions. Finally, CHO gene was amplified by PCR and cloned into STV28. RESULTS According to the morphological, cultural and biochemical tests, the isolated bacterium was identified as Rhodococcus sp. strain 501 and deposited in GenBank with accession number FN298676. Results showed that optimum temperature and pH for CHO activity were 35 degrees C and 7.5, respectively. Alignment of nucleotide sequence of CHO gene showed 99% homology with other bacterial CHO genes. CONCLUSION Rhodococcus sp. strain 501 produced significant levels of extracellular CHO in an optimized medium for a short period. CHO gene was cloned into cloning vector that can be a valuable tool for better identification and further studies on gene expression.

Abstract
BACKGROUND AND AIMS Hepatitis G virus/GB virus-C (HGV/GBV-C) is a newly identified member of the Flaviviridae family. Its clinical significance in chronic hepatitis C infection remains controversial. There is a geographical difference in the distribution of GBV-C in the world. The frequency of GBV-C infection among hepatitis C virus (HCV) infected patients varies. The aim of the current study was to determine the prevalence and genotypes of GBV-C among Iranian patients infected with chronic HCV. METHODS Infection with GBV-C was surveyed in 71 chronic confirmed hepatitis C infected patients. These samples were collected at the Digestive Disease Research Center (DDRC) of Shariati Hospital, Tehran, Iran from January to October 2007. The 5'-UTR region of GBV-C RNA was detected using a novel in-house touchdown nested reverse transcription polymerase chain reaction (RT-PCR), the products were sequenced and the results were aligned and phylogenically analyzed. RESULTS Of the 71 HCV-infected patients, 31 (43.6%) were found positive for GBV-C RNA. Sequencing and phylogenic analysis showed that the samples were Genotype 2 of GBV-C. CONCLUSIONS It seems that there is a high rate of GBV-C infection among Iranian patients infected with chronic HCV. In comparison with the six reference genotypes, it was observed that all the samples were categorized in Genotype 2 of GBV-C, prevalent in North America, Africa and in European countries.
