Background: Acyclovir (9-(2-hydroxyethoxymethyl) guanine) (ACV) is an acyclic nucleoside analogue that has shown a potent antiviral activity, and it is known to inhibit the replication of herpesviruses including herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2), varicella- zoster virus (VZV), and Epstein-Barr virus (EBV) in cell cultures and in animals. ACV is khown to be toxic to gonads,t...

introduction: the human papilloma virus (hpv) can play a role in the development of head and neck squamous cell carcinoma (scc). our aim was to assess the prevalence of hpv dna in scc of the larynx. the impact of hpv infection on patient survival was also evaluated.  materials and methods: this case-control study was performed in 44 patients with scc of the larynx (case group), while the contro...

Viral cell-free DNA (cfDNA) in plasma has been widely evaluated for detecting cancer and monitoring disease virus-associated tumors. We investigated whether the amount of cfDNA human T-cell leukemia virus type 1 (HTLV-1) correlates with state adult leukemia-lymphoma (ATL). HTLV-1 aggressive ATL was significantly higher than that indolent asymptomatic carriers. Notably, patients lymphoma represe...

The link between influenza virus (IV) viral load (VL) in respiratory samples and disease severity is not clearly established. This study was designed to assess IV-VL from flu patients admitted intensive care unit (ICU). Patients ICU for IV infection, as documented by RT-PCR, with failure were included the during 5 flu-seasons (2014–2018). Routine management parameters recorded. Real-time amplif...

discussion bladder over-distention and spontaneous bladder rupture, although very rare in ham/tsp, should be considered in a differential diagnosis of bladder rupture, especially in patients with a history of htlv1. introduction spontaneous bladder rupture is a rare manifestation of hyporeflexic bladder due to ham/tsp( human t-cell lymphotropic virus type 1 (htlv1) associated myelopathy/tropica...

three differentes continous cell lines (am 57. hela • vero) and primary cell culture of human embryo kidney are compared with regard to their .susceptibility for isolation of mumps v i r u s from saliva and cerebrospinal fluid. for this purfose the vero cell line appeared to be more suitable among the studied cell systems regarding the following reasons: it allows the highest pourcentage of mum...

herpetic keratitis which is resulted from herpes simplex virus type i, is considered the most common cause of corneal blindness that needs being diagnosed and treated in order to prevent irreversible eye effects. the best method to diagnose it is molecular method which has high sensitivity and exclusivity. the current study was done on 25 eye samples collected from patients referred to the feyz...

the herpes simplex virus type 1 (hsv-1) tegument protein, vp22 has been reported to have the property of intercellular transport. the previous studies have shown that following expression of a fusion protein containing vp22 it spreads to every cell in a monolayer and concentrates in the nucleus. in spite of these reports, some studies have shown that vp22 trafficking and its nucleus accumulatio...
