The cellular immune response to a European isolate of porcine reproductive and respiratory syndrome (PRRS) virus in animals recovered from the experimental infection has been studied in vitro. Peripheral blood mononuclear cells (PBMC) from these pigs proliferated specifically when they were stimulated with PRRS virus. This response was not detectable until 4 weeks after inoculation and remained...

Metastasis is the leading cause of death in patients with breast cancer (BC). It known that lesion regional lymph nodes by tumor cells more common tumors higher proliferative activity. Moreover, there literature evidence on effects cytokines and proteins upon migration potential tumor. The aim our work was to study correlation between concentrations cytokines, proteins, expression Ki-67 prolife...

Background: Recent research on several DNA fragments covering open reading frames (ORF) 1-37 shows a new genetic marker in ORF 6 which is specific for differentiating wild-type varicella-zoster virus (VZV) strains from Oka varicella vaccine strain. On the other hand, herpes simplex virus (HSV) genome analysis by restriction enzymes is used to differentiate types one and two of the virus and eve...

Since the initial onset of the current severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic from Wuhan, China in December 2019, the virus is now spread all around the world, and the disease is named COVID-19. Based on the WHO report on April 18, 2021, there are now more than 140 million confirmed cases and three millions deaths due to this disease[1]. The virus pathogenesis, cl...

Herpes Simplex Virus Type 1 (HSV-1) is a member of the Herpesviridae family that causes herpetic disease in human. During the last 25-30 years, many investigations have been conducted on pathogenesis and molecular biology of this virus in several countries. In Iran HSV-1 has been isolated from patients and detected using immunological techniques. In this study, we investigated the molecular asp...

Rinderpest virus (RPV) causes a severe disease of cattle resulting in serious economic losses in parts of the developing world. Effective control and elimination of this disease require a genetically marked rinderpest vaccine that allows serological differentiation between animals that have been vaccinated against rinderpest and those which have recovered from natural infection. We have constru...

objective(s): umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine.  the objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. materials and ...
