The overall seroprevalence of Neospora caninum antibodies was 107 from 800 (13.37±2.36%, α=0.05). Comparison of Neospora caninum serological status in age groups (<2 years, 2-4 years, >4 years) showed no significant difference (p>0.05). The prevalence of Neospora caninum was higher in the aborted cows than in non aborted cows. This is the first study on Neospora caninum antibodies in dairy cattle herds in Golestan province in the north east of Iran.

Human papilloma virus is suspected of causing extragenital cancers, including: cancers of the oral cavity, larynx, oesophagus and the lungs. More than 40 genotypes of HPV that infect the anogenital area are associated with a large spectrum of diseases from benign proliferation to invasive cancers. The aims of our study were to evaluate the prevalence of HPV-infection in non-cancer oesophageal lesions in Mazandran, North of Iran, and identify the prevalence of HPV in benign lesions. Methods: A total of 104 non-cancer oesophageal samples were collected in paraffinated blocks of tissue archived in pathology. After deparaffinization and DNA extraction, nested polymerase chain reaction (nPCR) method was performed by HPV L1 primer pairs (MY09/MY11 and Gp5+/GP6+). Results: Of 104 cases, 35 (33.7%) were HPV DNA positive. By histopathology, 61.5%, 31.8%, 30.4% and 30% of dysplasia, oesophagitis, normal tissue and ulcerative lesions were positive for HPV DNA, respectively. Also, the lower-third (distal) of the oesophagus had less infection of HPV DNA (18.8%) than the upper and middle-third (about 46%). The highest prevalence of HPV DNA was found in cases > 75 years old. Conclusion: To our knowledge, considering the highest rate of HPV-infection in people more than 75 years, we recommend the diagnostic procedures at a lower age. Also, the proximal part of the oesophagus is more infected with HPV than the distal part.

Advanced hepatocellular carcinoma (HCC) is a serious public health problem, with no effective cure at present. It has been demonstrated that the deregulation of microRNAs expression contributes to tumorigenesis. In HCC, miR-221 was shown to be up-regulated in more than 70% of the cases and was associated with higher tumor stage, metastasis and a shorter time to recurrence after surgery, suggesting an important pathogenic role. A tumor promoting function of miR-221 was proved in a transgenic mouse model, which was predisposed to the development of liver cancers. These findings suggested that miR-221 could represent a potential target for anti-tumor approaches. Novel adeno and adeno-associated viral vectors (AAVs) were developed: they were genetically modified to drive the expression of multiple binding sites for miR-221, the "miR-221 sponge&quo...

We exploited this miR-199 differential expression to develop a conditionally replication-competent oncolytic adenovirus, Ad-199T, and achieve tumor-specific viral expression and replication. To this aim, we introduced four copies of miR-199 target sites within the 3 ’ UTR of E1A gene, essential for viral replication. As consequence, E1A expression from Ad-199T virus was tightly regulated both at RNA and protein levels in HCC derived cell lines, and replication controlled by the level of miR-199 expression. Various approaches were used to asses in vivo properties of Ad-199T. Ad-199T replication was inhibited in normal, miR-199 positive, liver parenchyma, thus resulting in reduced hepatotoxicity. Conversely, the intrahepatic delivery of Ad-199T in newborn mice led to virus replication and fast removal of implanted HepG2 liver cancer cells. Th...

Therefore, the need for routine COVID-19 testing in this population was evaluated. Between 1st August and 30th October 2020, 150 cancer patients were included. Symptoms of COVID-19 infection were evaluated. All eligible individuals went through RT-PCR and serological tests for COVID-19. At the same time, 920 non-cancer patients were recruited from a random sample of individuals who were subject to routine molecular and anti-body screening tests. Of 150 cancer patients, 7 (4.7%) were RT-PCR positive. Comorbidity made a significant difference in the RT-PCR positivity of cancer patients, 71.4% positive versus 25.8% negative (P-value = 0.02). The average age for negative and positive groups was 53.3 and 58.2 respectively (P-value = 0.01). No significant difference was observed between cancer and non-cancer patients regarding COVID-19 antibody tests. However, cancer patients were 3 times less likely to...

Studying the periplasmic protein pattern of the recombinant bacteria, showed that the recombinant bacteria allowed a partially succeeded secretion of hGH into the periplasmic space. Remaining of unprocessed pelB::hGH fusion-protein was also observed in the E. coli cytoplasmic space. Comparing to IPTG induction, we have also used lactose as natural inducer for over-expression of rhGH in the present system. Our results demonstrated that lactose is as effective as IPTG for inducing expression of recombinant hGH. Introduction Variation of parameters involved in expression of recombinant protein is a phenomenon commonly observed in designing strategies for genetically engineering proteins.
