In most mouse strains, expression of a gene encoding sex-limited protein (Slp), an isotype of the fourth component of complement (C4), is induced by testosterone, or the gene is not expressed at all; however, in some wild-derived strains carrying H-2w7, H-2w16, or H-2w19 haplotype, Slp is expressed constitutively in the same way as C4. To examine the(More)
A polymerase chain reaction (PCR) method using sets of newly designed primers for rapid detection and simultaneous identification of dengue virus serotypes was developed and tested. The test is based on two sets of primers specific within the envelope (E) and non-structural (NS1) regions of the dengue-virus genome. Two sets of universal primers that bind to(More)
The serum level of the fourth component of complement (C4) in mice bearing the H-2k haplotype is only 1/10 to 1/20 of that of non-H-2k mice. We have analyzed C4 cDNA clones from B10.BR(H-2k) mouse liver and found aberrant C4 cDNA which contained a 200-base pair (bp) insertion between the exon 13 and exon 14 encoded sequences in addition to the normal C4(More)
Studies of the renal involvement in thalassemic syndromes have been varied and few. This study was designed to define the renal abnormalities associated with beta-thalassemia and to correlate the renal findings with clinical parameters. One hundred and four beta-thalassemic children with various disease severity were studied. The patients were divided into(More)
The 18S ribosomal RNA gene of Cryptococcus neoformans was amplified by polymerase chain reaction (PCR). The primers CPL1 and CPR4 were tested for their ability to amplify DNA from 30 strains of C. neoformans and 27 specimens of cerebrospinal fluid (CSF) from patients with cryptococcal meningitis. A 343 bp product was obtained and its specificity confirmed(More)
One-tube nested PCR was developed for diagnosis of pulmonary tuberculosis using sequences based on thel6SrRNA gene. The usage of primers 16SOL, 16SOR, 16SIL and 16SIR with optimized conditions could detect 555 bp DNA band from 21 species, 41 strains of mycobacteria and one isolate of Nocardia asteroides. It also revealed a specific 306 bp DNA band from 59(More)
BACKGROUND The aim of this study was to assess the use of qualitative one-tube nested polymerase chain reaction (PCR) for monitoring the treatment response in smear-positive pulmonary tuberculosis, and the factors determining the negative conversion of sputum smear, culture, and PCR during treatment. METHODOLOGY A total of 53 patients receiving a standard(More)
Partially purified thymidylate synthetase from Plasmodium berghei and mouse reticulocytes was characterized. The mol. wt of the enzyme from P. berghei was about twice that from mouse reticulocytes. The optimum pH of the enzyme from P. berghei was found to be 6.5-7.5 while that from the host was 7.0-8.0. The enzyme from P. berghei was more susceptible to pH(More)
