An in vitro study was conducted to know the veridical properties of silver nanoparticles synthesized from   locally available white button mushrooms (Agaricus bisporus). The characterized colloidal silver nanoparticles exhibited as an excellent virucidal property on viral strain Bacteriophage. The viral inactivation process was increased with increasing the concentration of colloidal s...

conclusions more than 40% of the hemophilic patients under 20 years of age in the present study had no immunity against hepatitis a, and 23% of hepatitis c patients had not had a hepatitis a co-infection yet. since hepatitis a can show a fulminant course in hepatitis c patients, vaccination against hepatitis a seems necessary in hemophilic patients in the region. background hemophilic patients ...

800x600 hepatitis b virus (hbv) infection is the main cause of chronic hepatitis, cirrhosis and hepatocellular carcinoma (hcc). several factors such as serum hbv dna level, genotype and specific viral mutations have been clarified to determine disease progression of chronic hepatitis b. among these, mutations can also occur in chronic hbv patients with antiviral treatment such as lamivudine the...
