Hepatitis B reactivation after kidney transplantation in hepatitis B surface antigen-negative, core antibody-positive recipients.

Nowadays, intensive immunosuppressive therapy including rituximab is commonly used prior to kidney transplantation (KT), raising concerns over hepatitis B virus (HBV) reactivation among hepatitis B surface antigen (HBsAg)-negative and anti-hepatitis B core (HBc)-positive KT recipients. Recent practice guidelines suggested watchful monitoring or antiviral prophylaxis for the first 6-12 months, the period of maximal immunosuppression. However, the actual risk for HBV reactivation, and whether short-term antiviral therapy in the early period is necessary, remains unclear.

Monitoring and Control of , a Vector of Zika Virus, Near Residences of Imported Zika Virus Patients during 2016 in South Korea.

Zika virus (ZIKV) is an arthropod-borne virus mainly transmitted by species. A total of nine of the 16 imported ZIKV reported cases during the mosquito season in the Republic of Korea (ROK), following the return of local nationals from foreign ZIKV endemic countries, were surveyed for . Surveillance and vector control of , a potential vector of ZIKV, and related species are critical for reducing the potential for autochthonous transmission in the ROK.

Pyruvate protection against endothelial cytotoxicity induced by blockade of glucose uptake.

We have previously demonstrated that the redox reactant pyruvate prevents apoptosis in the oxidant model of bovine pulmonary artery endothelial cells (BPAEC), and that the anti-apoptotic mechanism of pyruvate is mediated in part via the mitochondrial matrix compartment. However, cytosolic mechanisms for the cytoprotective feature of pyruvate remain to be elucidated. This study investigated the pyruvate protection against endothelial cytotoxicity when the glycolysis inhibitor 2-deoxy-D-glucose (2DG) was applied to BPAEC.

Immunomodulatory effect of caffeic acid phenethyl ester in Balb/c mice.

Caffeic acid phenethyl ester (CAPE), an the active component of propolis, is known to have anticarcinogenic, antiviral and various biological activities; however, the effect of CAPE on the immunomodulatory activity in vivo remains unknown. We have investigated the effect of CAPE on the immune system in female Balb/c mice. CAPE (0, 5, 10, 20 mg/kg) was given to mice orally for 14 days.
