Abstract
BACKGROUND Following rubella virus control, the most important cause of congenital infections is human cytomegalovirus (HCMV). Congenital CMV (cCMV) may happen both in primary and non-primary maternal infections. The present study aimed to screen cCMV in symptomatic newborns suspected of congenital rubella syndrome (CRS) in Iran. METHODS Out of 1629 collected infants' serum samples suspected of CRS but negative for rubella IgM, 524 samples were selected regarding cCMV complications. These samples were divided into two age groups: 1- one month and younger, 2- older than 1 month up to one year. Anti-HCMV IgM detection was performed on these serums. Then HCMV IgG avidity assay and HCMV DNA detection were carried out on all samples with positive and borderline results in IgM detection. RESULTS Herein, 3.67% of symptomatic infants aged one month and younger had positive and borderline HCMV IgM, 12.5% of which had a low avidity index (AI). HCMV IgM detection rate among symptomatic infants older than one month to one year was 14.5%. Identified genotypes in this study were gB-1(63.63%), gB2 (18.18%), and gB3 (18.18%), respectively. CONCLUSIONS This comprehensive study was performed on serum samples of symptomatic infants clinically suspected of cCMV from all over Iran. There was a good correlation between serology findings and PCR.

Abstract
Background SARS-CoV-2 genomic surveillance is necessary for the detection, monitoring, and evaluation of virus variants, which can have increased transmissibility, disease severity, or other adverse effects. We sequenced 330 SARS-CoV-2 genomes during the sixth wave of the COVID pandemic in Iran and compared them with five previous waves, for identifying SARS-CoV-2 variants, the genomic behavior of the virus, and understanding its characteristics. Methods After viral RNA extraction from clinical samples collected during the COVID-19 pandemic, next generation sequencing was performed using the Nextseq and Nanopore platforms. The sequencing data were analyzed and compared with reference sequences. Results In Iran during the first wave, V and L clades were detected. The second wave was recognized by G, GH, and GR clades. Circulating clades during the third wave were GH and GR. In the fourth wave, GRY (alpha variant), GK (delta variant), and one GH clade (beta variant) were detected. All viruses in the fifth wave were in GK clade (delta variant). In the sixth wave, Omicron variant (GRA clade) was circulating. Conclusions Genome sequencing, a key strategy in genomic surveillance systems, helps to detect and monitor the prevalence of SARS-CoV-2 variants, monitor the viral evolution of SARS-CoV-2, identify new variants for disease prevention, control, and treatment, and also provide information for and conduct public health measures in this area. With this system, Iran could be ready for surveillance of other respiratory virus diseases besides influenza and SARS-CoV-2.

Abstract
Background Human adenovirus (HAdV) is an important viral agent in children which can lead to severe acute respiratory infection (SARI). Reports on molecular epidemiology of HAdVs in Iran are limited. This case-control study is conducted to compare the HAdV infection rate and molecular epidemiology among two groups of children with and without respiratory symptoms in Tehran, Iran during 2018–2019. Methods Nested PCR was performed on 120 oropharyngeal swabs taken from children aged five and younger with SARI who were hospitalized as the case group, and 120 oropharyngeal swabs were collected from children of the same age without respiratory symptoms as the control group. For positive samples Sanger sequencing was done and a phylogenetic tree was drawn afterward. Results Out of 120 cases, 8 (6.6%) tested positive for eachHAdV types including 6 (75%) HAdV-B7, 1 (12.5%) HAdV-C2, and 1 (12.5%) HAdV-C6. Among the control group, out of 120 samples, 8 (6.6%) were positive comprising 5 (62.5%) HAdV-C5, 2 (25%) HAdV-F41, and 1 (12.5%) HAdV-C6. Conclusion The present study indicated a different viewpoint of HAdV molecular epidemiology in which the genotypes were compared in children with and without respiratory symptoms. HAdV prevalence was equally common in cases and controls but different genotypes were detected in these two groups. HAdV-B7 was the main type among children with SARI, dissimilar to children with no respiratory symptoms where HAdV-C5 was the predominant type. Detecting HAdV-F in oropharyngeal swabs was a rare finding, which requires further investigation.

Abstract
Background and Objectives Neuraminidase inhibitors (NAIs) as an imperative antiviral for influenza prophylaxis and treatment are being consumed worldwide. Increasing use of these antivirals might be associated with drug resistance. Regarding the significance of these variations, this study aimed to investigate the mutations occurring in the NA gene of influenza A viruses leading to oseltamivir resistance during 2017-2019 in Iran. Materials and Methods In this cross-sectional study, 40 influenza A (H1N1, H3N2) strains, isolated in National Influenza Center (NIC) from patients with Severe Acute Respiratory Infection (SARI) during 2017-2019 were subjected to RT-PCR and sequencing of NA complete gene. The frequency of oseltamivir resistance and variation of NA amino acids in these strains were investigated. Results No significant mutation conferring oseltamivir resistance was detected. However, NA antigenic sites in these strains depicted minor changes compared to the vaccine strains. Among H3N2 isolates, mutations at 329, 344, 346 and 385 and among H1N1 isolates mutations at 143 and 188 residues occurred in NA antigenic regions. Conclusion Evaluation of NA gene sequences, showed no resistant viruses to oseltamivir. Given that the viruses in the present study were the last viruses circulating in Iran before COVID-19 pandemic, the results will be beneficial to have a worthy comparison with the strains circulating after the pandemic. Constant monitoring for the emergence of drug-resistant variants and antigenic changes are crucial for all countries.

Abstract
Objective: To evaluate SARS-CoV-2 genome detection using pooled samples by RT-qPCR assay, compared to individual samples. Method: At first all samples were tested individually using two commercial methods targeting ORF1ab, NP and E genes. Then, four experimental groups of samples were pooled and evaluated using the same detection methods. Findings: Compared to the individual sample testing, the sample pooling conserved the sensitivity of the detection in all groups of pooled samples when the Ct value in single test was lower than 33. Conclusion: Specimen pooling may fail to detect positive samples with high Ct values. However, in scarcity of reagents or in population surveys, it could be considered as an alternative method in low prevalence settings.

Abstract
Aim: We investigated the genetic characterization of the respiratory syncytial virus (RSV) ON-1 genotypes and their different lineages based on the G gene among children <2 years of age presenting with acute respiratory tract infections in Tehran, Iran. Materials & methods: A phylogenetic tree from the Iranian samples and ON-1 strains of various parts of the world were constructed. The amino acid composition of the RSV G protein of the ON-1 genotype was mapped. Results: Human RSV ON-1 genotypes from the Iranian samples clustered in three lineages. The most common amino acid substitutions were as follows: X218Q, I240S, L289P, Y304H and L310P. Conclusion: Continuing molecular epidemiological surveys in other regions of Iran will provide deeper insight into the nature of this replacement of the dominant RSV genotype from GA2 to ON-1 in Iran.

Abstract
This study aimed to evaluate the prevalence of human rhinoviruses (HRVs) and the emergence of enterovirus D68 (EV-D68) in children. A total of 322 nasopharyngeal swab samples were provided from children with an initial diagnosis of upper and lower respiratory tract infections. A total of 34 and 70 cases were positive for EV-D68 and HRV, respectively. The phylogenetic analysis revealed that the clades A and B are the prevalent genotypes for EV-D68 and the HRV-positive samples belong to three types including HRV-A, HRV-B, and HRV-C. The results showed that EV-D68 and HRV-C are circulating in Iran especially in the winter.

Abstract
Background Miscarriage is the spontaneous pregnancy loss before 24 wk of gestation. The incidence rate of miscarriage over the past few decades has shown steady or even growing trends. Viral intrauterine infections are one of the probable etiological causes of miscarriage. Previous evidence have shown that human herpes viruses (HHVs) could be considered as the potential reasons for intrauterine infections and adverse pregnancy outcomes. Objective This case-control study aimed to detect HHV1-5 DNAs in placental tissues and assess their association with miscarriage during the first 24 wk of pregnancy in spontaneous and therapeutic abortions. Materials and Methods Placental tissues from 83 women with spontaneous abortions during the first and the second trimesters of pregnancy and 81 women with therapeutic abortion during the same gestational age were collected. The DNA extraction was performed by the phenol/chloroform method. A part of the DNA polymerase gene of HHVs was amplified with multiplex nested-polymerase chain reaction. The polymerase chain reaction products were subjected to sequencing. Results The results showed the presence of human cytomegalovirus genome in the placenta of both spontaneous (8.4%) and therapeutic (4.9%) abortions. No statistically significant differences were found between these two groups. The other investigated viruses were not detected here. Conclusion In conclusion, like some other studies, no correlation was detected between the HHVs placental infections and the increased risk of spontaneous abortions. In order to find the actual role of HHVs infections in miscarriage, further investigations should be performed on a larger sample size in different areas.

Abstract
INTRODUCTION H1N1 influenza virus, as an indoor/outdoor pathogen in air, can cause the flu-like illness and respiratory complication. The aim of this study was to evaluate the H1N1 influenza virus replication in pancreas and investigate the immune response against infected pancreas. MATERIAL AND METHODS First, mouse pancreas cell line was infected by H1N1 influenza A virus using intranasally and intravenously infection methods, and then the pancreas tissue was collected and pathology experiment was carried out. Next, the protein and genome of influenza virus were detected using immunocytochemistry and real-time PCR, respectively. In addition, serum cytokines and serum lipase were investigated using ELISA. RESULT The in-vitro results proved that the mouse pancreatic cell line can support influenza virus replication. The result also proved that influenza virus is capable to infect pancreas and induce pancreas damage. Further, the immune response in mice with infected pancreas exhibited a completely different pattern with that of mice infected through intranasal method. CONCLUSION It can be concluded that influenza virus can infect pancreas and change the influenza disease pathway, which might result in a pancreatic injury.

Abstract
Aim: We conducted a case–control study to examine the presence of BK virus (BKV) and Epstein barr virus (EBV) genome in prostate specimens of benign prostatic hyperplasia (BPH) and prostate cancer (PCa) in Iran. Materials & methods: 64 paraffin-embedded PCa specimens were included as case subjects and 57 paraffin-embedded BPH specimens as control. DNA extraction was carried out by phenol–chloroform technique and PCR for detection of BKV and EBV. Results: 90 (73%) out of 121 specimens were collected by prostatectomy and 31 (27%) by transurethral resection of the prostate. BKV was not detected in any of the samples and one positive EBV was reported. Conclusion: These findings provide further evidence against a causative role of BKV and EBV in the development of PCa.

Abstract
Aim: In this study we aimed to find the rate of human adenovirus (HAdV) infections and identify HAdVs molecular epidemiology in children younger than 5 years old with clinical diagnosis of severe acute respiratory infections in Iran. Patients & methods: A semi-nested PCR with in-house designed primers for HAdV was performed on 200 oropharyngeal swabs collected within 5 days from the onset of symptoms. The positive samples were subjected to sequencing and a phylogenetic tree was drawn. Results: Out of 200 specimens, 71 (35.5%) cases were positive for HAdVs. Detected strains matched with HAdV species B (80.3%), C (15.5%), D (2.8%) and E (1.8%). HAdV- B14/55 and HAdV-B3 were the most prevalent types, respectively. Conclusion: This study showed that infections with HAdV species B, were common in children, who were clinically diagnosed as severe acute respiratory infection cases in Iran. The results could be useful for future epidemiological researches.

Abstract
BACKGROUND Adeno-associated viruses (AAVs) have been found in human blood cells, cervical biopsies, and epithelial cell brushings, endometrium, and abortion material, which suggest their possible roles in the induction of miscarriage. OBJECTIVE In this case control study, the presence of AAV DNA in placental tissue of spontaneous and therapeutic abortions was compared. METHOD Placenta samples were evaluated for AAV DNA by hemi-nested PCR in miscarriages occurring in the first 24 weeks of pregnancy from therapeutic and spontaneous abortions. RESULTS Eighty-one therapeutic abortions (control group) and 83 spontaneous abortions (case group) were evaluated. Sixty-two (38.2%) of 164 abortions were AAV positive, including 35 (21.6%) spontaneous abortions and 27 (16.6%) therapeutic abortions. CONCLUSION There was no statistically significant difference between the presence of the AAV genome in spontaneous and therapeutic abortions. This observation was consistent with other studies in this area.

Abstract
HRSV is a principle cause of infant hospitalization, childhood wheezing and a common pathogen in the elderly. Limited information exists regarding HRSV genotypes in Iran. In order to better understand HRSV strain diversity, we performed an in-depth evaluation of the genetic variability of the HRSV F protein detected in children under two years of age that, presented with acute respiratory symptoms during 2015-2016 in Tehran. A total of 180 nasopharyngeal swabs were evaluated. The HRSV positive samples were genotyped for G and F gene sequences using RT-PCR and sequencing methods. Phylogenetic analysis was performed using the neighbor-joining and maximum likelihood methods. Genetic and antigenic characteristics of the F gene, nucleotide and amino acids in significant positions and immune system binding regions, as well as the p-distance, positive/negative selection site, linear epitopes and glycosylation sites were investigated in all selected sequences. Among the 83 HRSV positive samples, the Fifty-five cases were successfully sequenced. All of them were classified as subgroup A and belonged to the ON-1 genotype, which possessed 72-nt duplication in the G gene. This study is the first report on the emergence of ON-1 in Iran. ON-1 Iranian sequences clustered in three lineages according to virus fusion (F) gene variations. F gene sequence analysis showed that all genetic changes in the isolates from Iran were base substitutions and no deletion/insertions were identified. The low dN/dS ratio and lack of positively selected sites showed that the fusion genes found in the strains from Iran are not under host selective pressure. Continuing and long-term molecular epidemiological surveys for early detection of circulating and newly emerging genotypes are necessary to gain a better understanding of their epidemic potential.

Abstract
Viral infections have been considered as possible destructive factors that influence male fertility. The aim of this study was to determine the prevalence of human herpes viruses 1-5 (HHV1-5), adeno associated virus (AAV) and human papilloma virus (HPV) in semen and whether these influence semen quality. DNA extraction was performed using phenol-chloroform protocol, then three different nested-PCRs were done to detect HHV1-5, AAV and HPV DNAs in the semen samples. Of 145 samples, 66 (45.5%) were positive at least for one of the viruses. The genome detection rate of HSV1/2, VZV, EBV, HCMV, AAV and HPV were zero, 2.8%, zero, 1.4%, 27.6% and 19.3%, respectively. Of 66 positive samples for these viruses, 6 (4.1% of all samples) were positive for two viruses simultaneously. Here no association was found between variations in semen parameters related to fertility and detection of VZV, HCMV, AAV and HPV DNA in semen samples. It should be noted that the prevalence of different viruses in semen, and their relevance to male infertility, differs significantly due to the genome extraction and amplification methods or due to a real variation between study populations and geographical regions.

Abstract
OBJECTIVE Human papillomavirus (HPV) vaccination is currently not included in the national vaccination program in Iran. Regional data on the distribution of HPV types in women are important as they can predict the impact of currently available vaccines and help health policy makers to consider all the possibilities with regard to HPV vaccination. METHODS A total of 1,218 Iranian women with normal cervical cytology were included in this study. The presence of the HPV genome was investigated in all specimens by PCR assay, and all HPV-positive samples were genotyped. RESULTS Totally, HPV was detected in 88 samples (7.2%). According to different geographical regions, the HPV prevalence varied: the highest HPV prevalence was observed in the North (11.7%) and the lowest in the Center (4.5%) of Iran, and this difference reached a statistically significant level (p < 0.05). In this study, the most frequent HPV types were HPV 16, 18, 66, and 11, representing 63.8% of all HPV infections. CONCLUSION Based on this study, it is estimated that HPV vaccines could have a great impact on the prevention of cervical cancer in Iran. This study highlights the necessity of introducing educational programs in high schools, robust screening programs, and vaccination in Iran.

Abstract
Aim: In this study, we focused on the p53 codon 72 polymorphism and HPV infections as a possible contributing factor in susceptibility to prostate cancer (PCa). Methods: Eighty histopathologically confirmed prostate biopsies comprising of 40 cancer cases and 40 benign prostate hyperplasia cases were used. Results: A significant difference was not observed between HPV presence and PCa progression. Our results showed that the p53 protein with Arg (p53-Arg72) variant contributes to the development of PCa. Conclusion: There is a near-significant association between Arg/Arg polymorphism and PCa.

Abstract
Increased blood cytokines is the main immunopathological process that were attributed to severe clinical outcomes in cases of influenza A/H3N2 virus infection. The study was aimed to investigate the polymorphisms of IL-1β, IL-10, IL-17, and IL-28 genes to find the possibility of their association with the clinical outcome of influenza A/H3N2 virus infection among the infected patients in Iran. This is a Case-Control study in which influenza A/H3N2 virus positive confirmed with real-time PCR were the cases. DNA samples from groups were genotyped for polymorphisms in rs16944 (IL-1β), rs1800872 (IL-10), rs2275913 (IL-17), and rs8099917 (IL-28). Confidence interval (95%CI) and Odds ratio (OR) were calculated. IL-17 rs2275913 (GG and AG) were associated with risk of infection with that were statistically significant (P < 0.05, OR = 2.08-2.94). IL-1β (rs16944) (GG) was associated with reduced risk of infection (P < 0.01, OR = 0.46). Genotype GG and GT of IL-10 (rs1800872) were associated with increased risk of infection with influenza A/H3N2 virus (P < 0.05, OR = 2.04-2.58). In addition, IL-28 (rs8099917) genotypes GG (P < 0.05, OR = 0.49) and TG (P < 0.05, OR = 0.59) were associated with reduced risk of ILI symptom while genotype TT (P < 0.01, OR = 4.31) was associated with increased risk of ILI symptom. The results of this study demonstrated that polymorphisms of genes involved in the inflammatory and anti-inflammatory process affect the outcome of disease caused by influenza A/H3N2 virus. Thorough insight on host immune response at the time of influenza A virus infection is required to ensure adequate patient care in the case of feature outbreaks. J. Med.

Abstract
BACKGROUND Inverted papilloma (IP) is an uncommon disease which arises in the mucosal membrane of the nasal cavity and paranasal sinus. It has been proposed that human papillomavirus (HPV) is the causal agent in the pathogenesis of IP and plays a key role in the progression from benign IP to malignancy. As there are no prior studies that focus on an Iranian population, this study intended to characterize the prevalence of HPV types in benign and malignant forms of IP. METHODS In this retrospective study, we included a total of 40 IP patients [37 benign IP and 3 IP/squamous cell carcinoma (SCC)] who were referred to Amiralam Hospital in Tehran from 2004-2006. RESULTS HPV was detected in 18.9% and 100% of IP and IP/SCC cases, respectively. In all HPV positive cases of IP and IP/SCC cases, HPV6/11 and HPV16/18 were detected, respectively. Therefore, HPV types were different between the IP and IP/SCC patients, and this difference was statistically significant (p = 0.002). CONCLUSION This study suggests that HPV6 and 11 may be involved in the development of IP, but HPV16 and 18 likely play an important role in the progression from benign to malignant form of IP.

Abstract
Background: Although several studies have confirmed the association of xenotropic murine leukemia virus-related virus (XMRV) and prostate cancer, this association is still controversial, as most studies did not detect XMRV in prostate tissue samples. Furthermore, some genetic and epidemiological studies have highlighted a role for RNase L polymorphisms, particularly R462Q, in the progression of prostate cancer. Objectives: The focus of this study was on the association of XMRV and RNase L R462Q variants with the risk of prostate cancer in Iranian patients. Patients and Methods: In this case-control study, 40 and 80 individuals with sporadic prostate cancer and benign prostatic hyperplasia, respectively, were included. The presence of XMRV was evaluated by real-time polymerase chain reaction (PCR) of integrase and nested-PCR for the gag genes. The RNase L R462Q polymorphism analysis was carried out by PCR and sequencing. Results: In a total of 40 sporadic prostate cancer and 80 benign prostatic hyperplasia cases, no XMRV was detected by real-time PCR and nested-PCR. RNase L R462Q polymorphism analysis reveals that although there was an increase in the risk of prostate cancer correlated with the Q/Q allele of RNase L at position 462, the frequencies of the RNase L R462Q alleles were not statistically significant between the prostate cancer and benign prostatic hyperplasia groups (OR = 2.75 (95% CI = 0.67 - 11.3), P = 0.29). Conclusions: These results did not support the presence of XMRV in the samples with prostate cancer and showed that RNase L R462Q variants had relatively little or no impact on the risk of prostate cancer in Iranian population.

Abstract
Aim: Roles of NS gene of influenza A virus in virulence and replication are well established but extent of its variation in seasonal influenza A (H3N2) viruses in Iran is not well known. Materials & methods: NS gene of 37 (A/H3N2) virus isolates were sequenced and analyzed for information on genetic changes. Results: Data analysis of NS1 protein revealed two amino acid substitutions E26K and Q193R in almost all strains. Substitutions in T58P in 27.0%, A86S in 13.5% and each of V11G, M81I and P85T in 2.7% Iranian strains were also observed. Mutations in NS2/NEP protein were observed in K36E, Q101L and F107S. Conclusion: Many mutations were observed for the first time in Iranian strains. Their function remains to be determined.

Abstract
BACKGROUND Human papilloma viruses (HPV) have been detected in several types of cancers. Over the last few years, a possible correlation between HPV infection and colon cancers has been suggested. The aim of this study was to assess the presence of HPV-DNA in colon adenocarcinomas and adenomas to describe the relationship of HPV infection with these pathologic features. MATERIALS AND METHODS The study included formalin-fixed and paraffin-embedded tissue samples of 70 patients with colon adenocarcinoma and 30 patients with adenoma (as study group) and 30 tumor adjacent tissues (as control). HPV-DNA was purified and first amplified through MY09/MY11 and GP5+/GP6+ primers. Subsequently, for more precision, another PCR was performed using PGMY09/11 L1 consensus primer system. RESULTS All tested adenocarcinomas and adenomas as well as normal tumor adjacent tissues were negative for all types of HPV in two PCR assays. CONCLUSION Our results do not support the relationship between HPV infection and colon carcinoma or adenoma. Attributing a role to the HPV in the etiology of colon carcinogenesis will require further studies.

Abstract
BACKGROUND BK virus (BKV) is a common human polyomavirus which infects up to 90% of the general population with little clinical significance and with various epidemiological patterns of infection. Immune suppression is considered the main risk factor for BKV reactivation. Owing to their impaired cellular and humoral immunity, patients undergoing hemodialysis (HD) or peritoneal dialysis (PD) are at high risk of infectious diseases such as BKV infection. BKV presents with different distributions in different populations. This study aimed to determine the prevalence of BKV in Iranian patients with chronic renal disease undergoing HD and PD. METHODS Sixty-three HD patients and 33 PD cases from the main dialysis units in Tehran, Iran, were enrolled in the study. BK viremia was determined by qualitative polymerase chain reaction in all subjects. RESULTS Sixty-three cases under HD (mean age 59.3 ± 14.5 years) and 33 subjects on PD (mean age 53.7 ± 13 years) were enrolled in the study. The mean duration of HD was 59.1 ± 53.8 months and the dialysis interval was three times a week. In the PD group, the mean duration of dialysis was 38.9 ± 35.2 months. The prevalence of BK viremia was 3.03% in PD and 0% in HD subjects. CONCLUSIONS This study showed a low rate of BK viremia in chronic renal disease patients undergoing HD or PD. Differently from other studies in various populations, our results demonstrated low or absent BKV replication in Iranian dialysis patients, highlighting the varying epidemiological pattern of BKV distribution.

Abstract
Measles virus (MV) causes small and large outbreaks in Iran. Molecular assays allow identifying and the sources of measles imported from neighboring countries. We carried out a phylogenetic analysis of measles virus circulating in Iran over the period 2010-2012. Specimens from suspected cases of measles were collected from different regions of Iran. Virus isolation was performed on urine and throat swabs. Partial nucleoprotein gene segments of MV were amplified by RT-PCR. PCR products of 173 samples were sequenced and analyzed. The median age of confirmed cases was 2 years. Among all confirmed cases, 32% had unknown vaccination status, 20% had been vaccinated, and 48% had not been vaccinated. Genotypes B3 and D8 (for the first time), H1 and D4 were detected mainly in unvaccinated toddlers and young children. Genotype B3 became predominant in 2012 and was closely related to African strains. H1 strains were also found in small and large outbreaks during 2012 but were not identical to Iranian H1-2009 strains. A majority of the Iranian D4 strains during 2010-2012 outbreaks were linked to the D4 strain identified in the Pakistan in 2007. We identified a single case in 2010 belonging to D8 genotype with 99.7% identity to Indian isolates. Although the vaccination program is currently good enough to prevent nationwide epidemics and successfully decreased measles incidence in Iran, the fraction of protected individuals in the population was not high enough to prevent continuous introduction of cases from abroad. Due to increasing number of susceptible individuals in some areas, sustained transmission of the newly introduced viral genotype remains possible.

Abstract
BACKGROUND Preventing the seasonal or pandemic outbreak of influenza can be powerful and cost-effective. OBJECTIVES In this study, we constructed a novel virus-like particle (VLP) platform that contains two hemagglutinin (HA) subtypes and evaluated immunogenicity of constructed VLP in mice. MATERIALS AND METHODS This recombinant candidate vaccine model resulted in the expression of two HAs of H1N1 and H3N2 subtypes co-localized within a VLP. Following infection of insect cells with recombinant baculovirus co-expressing H1, H3 and M1 proteins, VLPs with size of 80-120 nm were self-assembled, budding, and released into the insect culture medium. The resulting VLPs which contained two different subtypes of hemagglutinin were purified by ultracentrifugation. The immunogenicity of VLPs was evaluated in mice following immunization. RESULTS Our data showed that vaccination using VLPs elicited robust levels of serum IgG, and viral neutralizing antibodies against A/PR8 (H1N1) and A/HK (H3N2) viruses. Following challenge with lethal dose of A/PR8 (H1N1) and A/HK (H3N2, vaccinated mice were protected, displaying no sign of weight loss and mortality compared to non-vaccinated control mice. CONCLUSIONS VLPs can serve as a promising vaccination strategy to control influenza virus.

Abstract
Human papillomavirus (HPV) infections are associated with benign and malignant lesions of the female and male anogenital tract. Currently the possible role of HPV infections in prostate carcinogenesis is a subject of great controversy. In this study we aimed to investigate the role of HPV infection in prostate carcinoma (PCa). The study included formalin-fixed paraffin-embedded tissue samples of 104 primary prostate adenocarcinoma cases and 104 control tissues of benign prostatic hyperplasia (BPH). HPV-DNA was purified and amplified through MY09/MY11 and GP5(+)/GP6(+) primers and subsequently subjected to sequencing. HPV-DNA was found in 13 of 104 (12.5%) PCa and 8 of 104 (7.7%) BPH samples. High-risk HPVs were detected in 10 of 13 (76.9%) PCa and 5 of 8 (62.5%) BPH samples with positive HPV-DNA. Low-risk HPVs were detected in 3 of 13 (23.1%) PCa and 3 of 8 (37.5%) BPH specimens with positive HPV-DNA. There was no significant difference between PCa and BPH specimens regarding HPV-DNA presence or the detection of high-risk and low-risk types of HPV. Our data do not support the role of HPV infection in prostate carcinoma. Further studies are required to elucidate the role of HPV infection in human prostate carcinogenesis.

Abstract
Surface gene mutants of hepatitis B virus (HBV) have been reported in a variety of patient groups. Because of limited data regarding these mutations in patients with occult HBV infections; we aimed to determine these mutations among high-risk patients with occult HBV infection. The presence of HBV-DNA was determined in patients with isolated anti-HBc by real-time polymerase chain reaction (PCR). Then, surface gene region was amplified by nested PCR and mutations were analyzed after sequencing. The mutations that resulted in nonfunctional hepatitis B surface antigen (HBsAg) were insertion of single nucleotide in 2 cases, which causes frameshift and single-nucleotide replacement, and premature stop codons at Leu15 and Gly10 in the other 2 cases. Amino acid substitution at amino acid position 207(S207N) was found in the other isolates. Our study suggested that "a" region mutations did not play a major role in HBsAg detection, and other genetic and nongenetic factors may be responsible for failure to detect HBsAg by routine laboratory tests.
