Idiopathic Thrombocytopenic Purpura (ITP) is caused by production of platelet autoantibody. Then ITP can be various viral infections, including Human Immunodeficiency Virus (HIV), Hepatitis C (HCV), cytomegalovirus, herpes simplex virus, Zika virus and others [1].

context since the introduction of highly active anti-retroviral regimen for human immunodeficiency virus-1 infection, a significant increase in the incidence of hepatocellular carcinoma has been reported in patients already chronically infected with hepatitis b virus and then given this form of regimen for their retroviral infection. evidence acquisition this phenomenon was initially attributed...

Eight calves between 16 and 18 weeks of age that were seronegative to bovine viral diarrhea virus (BVDV), bovine leucosis virus and bovine immunodeficiency-like virus were infected (day 0) intranasally with the type 2 noncytopathogenic Canadian 24515 field isolate of BVDV in order to evaluate the effect of BVDV infection on certain clinical, hematological and immunological parameters. All virus...

The human SAMHD1 protein is a novel retroviral restriction factor expressed in myeloid cells. Previous work has correlated the deoxynucleotide triphosphohydrolase activity of SAMHD1 with its ability to block HIV-1 and SIV(mac) infection. SAMHD1 is comprised of the sterile alpha motif (SAM) and histidine-aspartic (HD) domains; however the contribution of these domains to retroviral restriction i...

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,...

human immunodeficiency virus (hiv) infection has been associated with cardiac disease, including anatomical or functional disturbance to the heart. cardiomyopathy (cmp) is one of these disturbances that have been associated with high rates of morbidity and mortality. in this review article, several aspects of potential relationships between hiv infection and cardiomyopathy development have been...

Bovine leukemia virus (BLV) is a valuable model system for understanding human T-lymphotropic virus 1 (HTLV-1); the availability of an infectious BLV clone, together with animal-model systems, will help to explore anti-HTLV-1 strategies. Nevertheless, the specificity and inhibitor sensitivity of the BLV protease (PR) have not been characterized in detail. To facilitate such studies, a molecular...

Viral cycle progression depends upon host-cell processes in infected cells, and this is true for bovine viral diarrhoea virus (BVDV), the causative agent of BVD that is a worldwide threat to the bovine industry. Heme oxygenase-1 (HO-1) is a ubiquitously expressed inducible isoform of the first and rate-limiting enzyme for heme degradation. Recent studies have demonstrated that HO-1 has signific...
