Enhanced efficiency of swine wastewater treatment by the composite of modified zeolite and a bioflocculant enriched from biological sludge.

A high-ammonia-resistant strain was firstly isolated from activated sludge and applied to harvest a bioflocculant from a swine wastewater. Enhancement of swine wastewater treatment was investigated by a composite of the harvested bioflocculant and a zeolite modified by integrating calcinations with MgO at 400°C. Results have demonstrated that 71.

Apoptosis pathway of liver cells in chronic hepatitis.

Aim: To study the pathway of apoptosis in chronic liver disease and the role of mitochondria in programmed cell death.

Methods: Liver biopsy specimens from 72 cases of chronic hepatitis and 29 cases of post hepatitis cirrhosis were studied. The pro-apoptotic protein Fas, FasL, Bax and the anti-apoptotic protein Bcl-2, Bcl-x(L), Bcl-2 alpha were studied immunohistochemically by SP method.

[Localization of hepatitis C virus core protein in the nucleus of peripheral blood mononuclear cells of hepatitis C patients].

Background: To study the significance of the expression of HCV core protein in PBMC of patients with chronic hepatitis C and to evaluate the relationship between HCV core protein expression and clinical states.

Methods: Identification of HCV protein antigen (Ag) in PBMC of 66 hepatitis C patients by immunohistochemical method and clinical status of the patients with HCV protein positive expression were investigated. In 27 out off 66 patients the HCV RNA and HCV Ag in PBMC were detected with RT-PCR and immunohistochemical method.
