Y chromosomes are different from other chromosomes because of a lack of recombination. Until now, complete sequence information of Y chromosomes has been available only for some primates, although considerable information is available for other organisms, e.g., several species of Drosophila. Here, we report the gene organization of the Y chromosome in the(More)
The expression levels of various cytokines increase with the progression of HIV-1 infection. However, the effects of antiretroviral therapy (ART) on serum cytokine levels have not been fully determined. In this study we measured serum cytokine levels of 35 HIV-1-infected Japanese adults. We first performed a cross-sectional study and observed that TNF-α,(More)
Three beta-glucosidase- and two endoglucanase-encoding genes were cloned from Aspergillus oryzae, and their gene products were displayed on the cell surface of the sake yeast, Saccharomyces cerevisiae GRI-117-UK. GRI-117-UK/pUDB7 displaying beta-glucosidase AO090009000356 showed the highest activity against various substrates and efficiently produced(More)
A novel promoter from a hemolysin-like protein encoding the gene, hlyA, was characterized for protein overexpression in Aspergillus oryzae grown in solid-state culture. Using endo-1,4-β-glucanase from A. oryzae (CelA) as the reporter, promoter activity was found to be higher than that of the α-amylase (amyA) and manganese superoxide dismutase (sodM) genes(More)
For efficient production of isoflavone aglycones from soybean isoflavones, we isolated three novel types of β-glucosidase (BGL1, BGL3, and BGL5) from the filamentous fungi Aspergillus oryzae. Three enzymes were independently displayed on the cell surface of a yeast Saccharomyces cerevisiae as a fusion protein with α-agglutinin. Three(More)
Impaired renal function caused by tenofovir disoproxil fumarate (TDF) is considered reversible by discontinuing TDF administration, but there are occasional cases of incomplete recovery. We investigated the recovery of renal function after the discontinuation of TDF. Subjects comprised patients who had been started on TDF but in whom it was later(More)
Disseminated penicilliosis-an AIDS-indicator disease in Southeast Asian countries -but not Japan- is a systemic fungal infection caused by Penicillium marneffei. A 30-year-old HIV-positive Japanese man visiting Southeast Asia three months before admission and reporting fever, general fatigue, and enlarged lymph nodes lasting over one month was admitted for(More)
BACKGROUND Viral reservoir size refers to cellular human immunodeficiency virus-1 (HIV-1) DNA levels in CD4(+) T lymphocytes of peripheral blood obtained from patients with plasma HIV-1-RNA levels (viral load, VL) maintained below the detection limit by antiretroviral therapy (ART). We measured HIV-1 DNA levels in CD4(+) lymphocytes in such patients to(More)
Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a recently reported rare disease entity characterized by fibrotic thickening of the pleural and subpleural parenchyma predominantly in the upper lobes in idiopathic interstitial pneumonias (IIPs). Because the clinical features of this rare disease are not fully elucidated, we examined the clinical(More)
We treated three cases of fungemia in HIV-infected patients. These cases were caused by Candida albicans, Cryptococcus neoformans, and Penicillium marneffei, respectively, and all were diagnosed through the use of mycobacterial blood culture bottles. Although the detection of the etiologic agents of fungal infection is difficult, it has been shown that(More)
