herpes simplex virus (hsv) is one of the common pathogenic viruses of humans bing. this study aimed to determin anti-herpes virus activity of mentha piperita extracts in vitro. mentha piperita extracts can inhibit hsv infection when the cells treated before viral adsorbtion. hsv-1 were also inhibited by menthol after viral adsorption. hsv-1 viral particles were directly inhibited and viral yiel...
Background: Sodium valproate, an anticonvulsant drug, is reported to stimulate Human Immunodeficiency Virus type 1 and Human cytomegalovirus replication. Since epileptic patients undergoing sodium valproate therapy may suffer from various virus infections, the effect of this drug on replication of viruses especially those affecting neuronal tissues such as Herpes simplex virus type 1 is worthy ...
Cancer, as one of the most serious public health problems, is the second-leading cause of death in the world after cardiovascular disease. The number of patients and the resulting mortality are increasing worldwide; therefore, early diagnosis, prevention, and effective treatment of cancer are very important. Current treatments such as chemotherapy and radiation therapy are often non-selective a...
conclusions after seven consecutive passages of both cell cultures, the h9n2 virus showed similar antigenicity, also no change on viral titer level and virus replication behavior in adaptation was found. the results highlighted the use of a549 cells for efficient virus isolation. results the influenza virus infectivity was not significant difference in these cells in the presence of trypsin. th...
Background and Aims: The emergence of drug-resistant influenza viruses has become a serious threat for human and animal populations. Glycyrrhiza glabra (Gg) is a traditional medicine clinically used for the treatment of viral respiratory infection symptoms in most countries. We evaluated the effects of the herb on influenza virus replication in human lung cultured cells (A549) following the det...

Objective: Influenza virus, which is associated with high level of morbidity and mortality, has been recently considered a public health concern; however, the methods of choice to control and treat it are limited. Our previous study showed anti-influenza virus activity of pomegranate peel extract (PPE). In this study, the mechanism through which PPE acts against influenza virus...
The Varicella-Zoster Virus (VZV) genome contains both cis-acting and trans-acting elements, which are important in viral DNA replication. The cis-acting elements consist of two copies of oriS, and the trans-acting elements are those genes whose products are required for virus DNA replication. It has been shown that each of the seven genes required for ori-dependent DNA synthesis of Herpes Simpl...
Introduction: Avian influenza viruses are considered as a serious threat to human and animal health. An increase in expression of proinflammatory cytokines and type I IFN genes, as well as host cell death responses contribute to the pathogenesis of influenza infection. Hence, this study aimed to evaluate the growth dynamics of subacute avian influenza virus in human respiratory alveolar epithel...
conclusions our study demonstrated that a low dose of rmp could inhibit hbv transcription and replication, which is dependent on the appearance of hbx in vivo. results rpb5-mediating protein could inhibit hbv transcription and replication in groups transfected with the 1.2 wt and hbx. the inhibitory effect disappeared in the 1.2x (-) groups, yet it reappeared in the groups co-transfected with 1...
