In an effort to develop potent human purine nucleoside phosphorylase (PNP) inhibitors as immunosuppressive and chemotherapeutic agents, several 8-aminoguanine derivatives were synthesized and evaluated as potential PNP inhibitors. These studies were designed to investigate the hydrophobic effect of a substituent on the N-9 of the purine heterocycle and/or(More)
Male ICR mice were exposed to mosquito-coil smoke with d-allethrin or without d-allethrin at airborne particles concentration of 1.27 mg/m3, 7 h/day, 7 days/week for 1, 3, 6, and 12 months. Additional groups of air exposure animals served as controls. At 1 month after exposure, the histopathological lesions included the loss of cilia, and the alteration of(More)
OBJECTIVE DDX3 has diverse biological functions in translation control, cell growth regulation, and tumor progression. Oral squamous cell carcinoma (OSCC) is a common malignant tumor worldwide with a poor clinical prognosis. The impact of DDX3 expression in OSCC is seldom discussed. MATERIALS AND METHODS Tumor tissues and adjacent normal tissues were(More)
Parvovirus B19 involvement was investigated in 30 children with severe aplastic anaemia. Active or recent parvovirus B19 infection, as shown by B19 DNA viraemia, positive B19 specific IgM antibodies, or both, was diagnosed in six patients. There were no other plausible causes. We suggest that parvovirus B19 infection might be associated with severe aplastic(More)
Arrestin domain-containing protein 3 (ARRDC3) is a member of the mammalian α-arrestins family, which has been identified as a tumor suppressor gene in human breast cancer, but its functions are still not clear in human prostate cancer (PCa). The purpose of the present study was to investigate clinical significance, biological functions and underlying(More)
