BACKGROUND Taiwan established a nationwide surveillance system for human immunodeficiency virus (HIV) infection in 1989 and adopted a policy to provide all HIV-infected citizens with free access to highly active antiretroviral therapy (HAART) beginning in April 1997. This provided an opportunity to determine the effect of the widespread use of HAART on the(More)
The structures of two major phosphoglycolipids from the thermophilic bacteria Thermus oshimai NTU-063, Thermus thermophilus NTU-077, Meiothermus ruber NTU-124, and Meiothermus taiwanensis NTU-220 were determined using spectroscopic and chemical analyses to be 2'-O-(1,2-diacyl-sn-glycero-3-phospho) -3'-O-(alpha-N-acetyl-glucosaminyl)-N-glyceroyl alkylamine(More)
The thermophilic bacterium Thermus aquaticus NTU103 harbors a 1,965-bp plasmid, pTA103. Sequencing analysis revealed that pTA103 contains two open reading frames. One of the open reading frames (orf2) shares no significant homology with protein in the data bank. The other one has 50% similarity and 34% identity with RepA-like protein of pRm1132f, which is a(More)
The purpose of the study was to evaluate the reliability and validity of the two generic instruments, the WHOQOL and the SF-36, for assessing health-related quality of life in 224 patients with HIV infection. The internal consistency ranged from 0.75 to 0.86 across the WHOQOL-BREF domains and from 0.72 to 0.93 across the SF-36 scales. The scores of all(More)
Two novel filamentous bacterial isolates, strains WR-30T and WR-220, with an optimum growth temperature of approximately 55-60 degrees C were isolated from Wu-rai hot springs in the northern part of Taiwan. These isolates were aerobic, thermophilic, non-sporulating, red-pigmented and heterotrophic and formed extremely long, filamentous trichomes from cells(More)
Five new polyketides that contain tetramic acids, myceliothermophins A-E, were isolated from the thermophilic fungus Myceliophthora thermophila. Two sets of 5-alkyl-5-hydroxyl (or 5-methoxyl)-1H-pyrrol-2(5H)-one diastereomers, myceliothermophins A/B and C/D, were separated as pure compounds by using silica-gel column chromatography and recycling(More)
Two novel thermophilic bacterial strains, with an optimum growth temperature of between 50 and 60 degrees C, were isolated from the Chi-ban Hot Springs in eastern Taiwan. Strains CB-225 and CB-226(T) were aerobic, thermophilic, non-sporulating, yellow-pigmented heterotrophic organisms. These strains exhibited an unusual denitrification reaction, reducing(More)
Two novel bacteria, with an optimum growth temperature of approximately 60 degrees C, were isolated from Lu-shan hot springs in the central region of Taiwan. These isolates were aerobic, thermophilic, halotolerant, pink-pigmented, heterotrophic and resistant to gamma-radiation. Both pleomorphic, short, rod-shaped cells and coccoid cells were observed.(More)
The structure of a major glycolipid isolated from the thermophilic bacteria Thermus oshimai NTU-063 was elucidated. The sugar and fatty acid compositions were determined by GC-MS and HPLC analysis on their methanolysis and methylation derivatives, respectively. After removal of both O- and N-acyl groups by alkaline treatment, the glycolipid was converted to(More)
A gene encoding thermostable Lon protease from Brevibacillus thermoruber WR-249 was cloned and characterized. The Br. thermoruber Lon gene (Bt-lon) encodes an 88 kDa protein characterized by an N-terminal domain, a central ATPase domain which includes an SSD (sensor- and substrate-discrimination) domain, and a C-terminal protease domain. The Bt-lon is a(More)
