Hepatitis B virus (HBV) infection is contagious with transmissiobn vertically or horizontally by blood products and body secretions. Over 50% of Iranian carriers contracted the infection prenatally, making this the most likely route of transmission of HBV in Iran. To evaluate the resistance to adefovir (ADV) therapy in patients with chronic hepatitis B infection, a study was conducted on 70 pat...

The predictors for fatal adenovirus (AdV) pneumonia among immunocompetent adults are unclear. Laboratory-confirmed, hospitalized AdV pneumonia adults were prospectively enrolled in Beijing Chao-Yang hospital from March to June 2013. Clinical data and serial whole blood and respiratory tract secretions from such patients were collected. Quantitative real-time polymerase chain reaction was perfor...

OBJECTIVES We investigated the long-term efficacy of entecavir (ETV) + adefovir (ADV) combination therapy versus ETV monotherapy in lamivudine (LAM)-resistant chronic hepatitis B (CHB) patients who failed to respond to ADV rescue therapy. METHODS A total of 91 ADV refractory patients with prior LAM resistance received ETV (1.0 mg/day) + ADV (10 mg/day) combination therapy (group A, n = 45) or...

A portion of a cDNA clone containing coding sequences for both structural proteins (VP1 and VP2) of Aleutian mink disease parvovirus (ADV) was inserted into recombinant vaccinia viruses, VV:ADSP. Immunohistochemical staining of VV:ADSP-infected cells revealed that the ADV antigen was readily detected and localized in the nuclei of infected cells. Analysis of VV:ADSP-infected cell lystates indic...

The critical assessment of bovine adenoviruses (BAdV) as indicators of environmental fecal contamination requires improved knowledge of their prevalence, shedding dynamics, and genetic diversity. We examined DNA extracted from bovine and other animal waste samples collected in Wisconsin for atadenoviruses and mastadenoviruses using novel, broad-spectrum PCR primer sets. BAdV were detected in 13...

Atlantic salmon (Salmo salar) juveniles were reared under simulated conditions of normal photoperiod (LDN) or short days (LD 9:15) and ambient temperature (AMB: normal temperature increases in April) or an advanced temperature cycle (ADV: temperature increases in February). Under both photoperiod conditions, the timing of increased and peak levels of gill Na(+),K(+)-ATPase activity were not alt...

Adenoviral vectors (AdV) activate multiple signaling pathways associated with innate immune responses, including mitogen-activated protein kinases (MAPKs). In this study, we investigated how systemically-injected AdVs activate two MAPK pathways (p38 and ERK) and the contribution of these kinases to AdV-induced cytokine and chemokine responses in mice. Mice were injected intravenously either wit...

BACKGROUND Islet transplantation has the potential for treating type I diabetes; however, its widespread clinical application is limited by the massive apoptotic cell death and poor revascularization of transplanted islet grafts. METHODS We constructed a surface-modified adenoviral vector with RGD (Arg-Gly-Asp) sequences encoding human X-linked inhibitor of apoptosis and hepatocyte growth fac...
