Abstract Background Coronavirus Disease 2019 (COVID-19) is a viral pandemic disease that may induce severe pneumonia in humans. In this paper, we investigated the putative implication of 12 vaccines, including BCG, OPV and MMR protection against COVID-19. Sequences main antigenic proteins vaccines SARS-CoV-2 were compared to identify similar patterns. The immunogenic effect identified segments ...

conclusions our data show that not only general health and physical activity were preserved but also health perception may be better among hd patients with viral hepatitis. background there are surprisingly a few studies that evaluate the impact of chronic viral hepatitis, which is common in hd (hemodialysis) patients, on hrqol (health related quality of life). objectives we conducted a study t...

New information has prompted revision of the conceptual framework for considering the epidemiology and virology of viral hepatitis. The means are now at hand to identify infections due to either Hepatitis A or B, as well as to implicate other etiologic agents in hepatitis. Immunologic evidence of variation in the antigens associated with Hepatitis B, and possibly in Hepatitis A, may explain som...

viral hepatitis is one of five infectional factors cause early death in all over the world. every day at least one million people die because of viral hepatitis. six hepatitis viruses have been known until now. they are a, b, c, d, e, g, and it is probable that at least two other kinds i.e. f, and h, will be known soon. only hepatitis b is a dna virus, and the others are rna viruses. all viruse...

hepatomegaly, decrease in the liver paranchymal echo and increase in the gallbladder wall thickness has been shown in acute viral hepatitis. the present study was done to determine sonographic changes in acute viral hepatitis. we performed liver and bile ducts sonography and specific tests on 42 patients (mean age: 31.5 and 61% male) with acute viral hepatitis. gallbladder wall thickness was se...

Hepatitis A virus (HAV) infection occurs worldwide and is an important cause of acute viral hepatitis in the US. In this review, I cover the epidemiology, course of infection, clinical manifestations, serological responses, and prevention of this infection. Although most patients completely recover from this disease, elderly patients have a substantial mortality risk. Recently licensed vaccines...

Abstract Background Methadone therapy clinics have been recently introduced in Tanzania, aiming at reducing risk behaviors and infection rates of viral hepatitis HIV among people who use drugs. The objective this study was to estimate the prevalence, associated factors knowledge level these conditions drugs attending a methadone clinic Tanzania. Methods We enrolled 253 People using receiving th...

Background: Today, several vaccines have been developed to prevent infectious diseases. The older first-generation vaccines may have many problems. In this regard, genetic engineering plays an important role using tools such as shuttle vectors to develop recombinant DNA vaccines that usually include plasmid constructed so that can propagate in two different host species. The present study revie...
