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,...

the co-existence of acquired immune  deficiency syndrome (aids) and tuberculosis is a major cause of morbidity and mortality because of a widespread organ involvement. the gastrointestinal tract is a common site for localization of opportunistic  microorganisms  in aids. however, surgical abdominal  emergencies such as intestinal perforation resulted from tuberculosis are uncommon  in these pat...

BACKGROUND The hepatitis B, hepatitis C, human immunodeficiency viruses and Treponema pallidum are important causes of infectious diseases concern to public health. METHODS Between 2010 and 2014, we used an automated chemiluminescence microparticle immunoassay to detect the hepatitis B, hepatitis C, and human immunodeficiency viruses as well as Treponema pallidum (the rapid plasma regain test...

INTRODUCTION Replication of the human immunodeficiency virus involves an obligatory step of reverse transcription of the viral ribonucleic acid genome into a double-stranded deoxyribonucleic acid, and subsequent integration of the deoxyribonucleic acid into the human chromatin to form the proviral deoxyribonucleic acid. This proviral human immunodeficiency virus deoxyribonucleic acid is a criti...

CD4 antigen levels in sera from asymptomatic intravenous drug users and homosexuals and patients with lymphadenopathy, acquired immunodeficiency syndrome-related complex, or acquired immunodeficiency syndrome were quantitated. Like soluble CD8, CD4 antigen levels were elevated in human immunodeficiency virus-seronegative asymptomatic intravenous drug users and homosexuals, probably reflecting i...
