background patients with beta thalassemia suffer from increased susceptibility to infections and putridity plays a major role in the patient's morbidity and mortality. the risk of transfusion-transmitted viral infection is well known in these patients. however, there is dearth of information about the seroprevalence of herpes simplex virus (hsv) infection in patients with beta thalassemia in li...

background: human pathogens that can cause infertility may also affect sperm count and quality. viral infections can be considered as direct and/or indirect cause of male factor infertility. objective: our goal was to investigate the prevalence of herpes simplex virus in the semen of infertile men attending the avicenna infertility clinic, and to compare it with the herpes virus serology result...

Brown alga, Turbinaria conoides was successively extracted with n-hexane, cyclohexane, methanol and ethanol:water (1:1). The extracts were evaluated for antibacterial and antifungal activities by disc diffusion method. Minimal inhibitory concentration was determined for active extracts by broth dilution method. The antiviral activity and cytotoxicity of the extracts were tested in human embryon...

avicennia marina (avicenniaceae) is a species of mangrove tree used for treatment of small pox lesions in persian folk medicine. the antiviral activity of methanol, ethanol, water, chloroform and n-hexane extracts was evaluated against hiv-1 and hsv. methanol extract had the highest antiviral activity and the most polar fraction of this extract (fraction d) inhibited hsv with ti and si values o...

background: during the recent years, significant progress has been achieved on development of novel anti-viral drugs. natural products are assumed as the potential sources of novel anti-viral drugs; therefore, there are some previous studies reporting the anti-viral compounds from venomous animals. based on the significant value for tracing of non-toxic anti-viral agents from natural resources,...

background: colorectal cancer is one of the most common malignancies worldwide with more than one million new cases diagnosed each year . the aim of this study is to investigate the prevalence of herpes simplex virus and epstein-barr virus in patients with colorectal carcinomas and polyps in comparison with healthy subjects by using the polymerase chain reaction technique. methods: in this anal...
