rickettsia honei: a spotted fever group rickettsia on three continents.rickettsia honei (also known as strain tt-118) has been detected on three continents. originally isolated in thailand in 1962 (and confirmed in 2001), it has also been detected on flinders island (australia) in 1993 and in texas (usa) in 1998. on each continent it has been associated with a different species of tick. the original isolate (thai tick typhus strain tt-118) was from a pool of larval ixodes and rhipicephalus ticks. later it was detected in i. granulatus from rattus rattus. its pathog ...200312860601
association between interleukin-8 gene alleles and human susceptibility to tuberculosis disease.interleukin (il)-8 is involved in the pathogenesis of human tuberculosis (tb). however, the contribution of polymorphisms of the il-8 gene and its receptor genes cxcr-1 and cxcr-2 to human tb susceptibility remains untested. in a case-control study, white subjects with tb disease were more likely to be homozygous for the il-8 -251a allele, compared with control subjects (odds ratio [or], 3.41; 95% confidence interval [ci], 1.52-7.64). african americans with tb also showed an increased odds of be ...200312870115

molecular analysis of mycobacterium kansasii isolates from the united states.we studied the population genetics of mycobacterium kansasii isolates from the united states by pcr restriction enzyme analysis (pra) of the 441-bp telenti fragment of the hsp-65 gene and pulsed-field gel electrophoresis (pfge) of genomic dna with the restriction endonucleases asei, drai, and xbai, and we compared the patterns to those previously reported from france and japan. by pra, 78 of 81 clinical isolates (96%) from the united states belonged to subspecies i. with pfge, 28 asei patterns, ...200414715741
the genetics of obesity in mexican americans: the evidence from genome scanning efforts in the san antonio family heart study.recent estimates indicate that approximately 18% of the population in the united states can be considered obese (defined as a body mass index [bmi] > or = 30), and this rate is even higher among ethnic populations such as mexican americans. this figure becomes very significant given the strong evidence for obesity as a major risk factor for a variety of chronic diseases including type 2 diabetes mellitus and coronary heart disease. the search for genes involved in the expression of obesity has b ...200314763601
a founder mutation of the msh2 gene and hereditary nonpolyposis colorectal cancer in the united states.hereditary nonpolyposis colorectal cancer (hnpcc), also known as lynch syndrome, is caused by mutations in the mismatch repair genes and confers an extraordinarily high risk of colorectal, endometrial, and other cancers. however, while carriers of these mutations should be identified, counseled, and offered clinical surveillance, at present the mutations are not tested for in mutation analyses.200414871915
development of a human pancreatic islet-transplant program through a collaborative relationship with a remote islet-isolation center.with the development of the edmonton protocol, pancreatic islet transplantation (pit) now offers insulin-dependent diabetic patients metabolic stability. the pit food and drug administration (fda) regulations, pancreatic islet isolation (pii) techniques, and clinical pit protocols are challenging and make pit program development daunting.200414966428
combined use of enzyme-linked immunosorbent assay and flow cytometry to detect antibodies to trypanosoma cruzi in domestic canines in texas.canines may be sentinels and/or reservoirs for human trypanosoma cruzi exposures. this study adapted a method originally designed for human diagnostics to detect serum immunoglobulin g to t. cruzi in canines. the method combined an enzyme-linked immunosorbent assay (elisa) for screening and flow cytometry detection of anti-live trypomastigote antibodies (alta) for confirmation. the assays were optimized by using known positive and negative control canine sera, and cutoff values were established. ...200415013981

fumonisins disrupt sphingolipid metabolism, folate transport, and neural tube development in embryo culture and in vivo: a potential risk factor for human neural tube defects among populations consuming fumonisin-contaminated maize.fumonisins are a family of toxic and carcinogenic mycotoxins produced by fusarium verticillioides (formerly fusarium moniliforme), a common fungal contaminant of maize. fumonisins inhibit ceramide synthase, causing accumulation of bioactive intermediates of sphingolipid metabolism (sphinganine and other sphingoid bases and derivatives) as well as depletion of complex sphingolipids, which interferes with the function of some membrane proteins, including the folate-binding protein (human folate re ...200415051815
the geographic distribution of potential risks posed by industrial toxic emissions in the u.s.the toxics release inventory (tri), compiled annually by the epa, has emerged as the most comprehensive database on industrial toxic emissions in the u.s. while various risk indicators and pollutant weighting methods have been developed to compare tri emissions, these measures are rarely used to examine the geography of potential risks posed by toxic emissions at the national scale. this article provides a geographic perspective on the evaluation of industrial pollution by exploring the spatial ...200415055926

phoning logistics in a longitudinal follow-up of batterers and their partners.more needs to be known about the phoning logistics of interviewing subjects for longitudinal follow-up studies in the domestic violence field. using phoning logs from a 4-year follow-up of batterer intervention, the authors calculated the number, results, and costs of phone calls from a subsample of 100 men and 138 women. the number of calls is high (5.5 per man and 7.1 per woman), locators play a substantial role (for 25% of the men and women), and mailed questionnaires are a useful supplement ...200415186534
achievement of insulin independence via pancreatic islet transplantation using a remote isolation center: a first-year review.owing to advances in both immunosuppressive protocols and pancreatic islet isolation techniques, insulin independence has recently been achieved in type 1 insulin-dependent diabetics (iddm) via pancreatic islet transplantation (pit). although the dissemination of immunosuppressive protocols is relatively easy, transferring the knowledge and expertise required to isolate a large number of quality human islets for transplantation is a far greater challenge. therefore, in an attempt to centralize t ...200415194393

genetic diversity of human pathogenic members of the fusarium oxysporum complex inferred from multilocus dna sequence data and amplified fragment length polymorphism analyses: evidence for the recent dispersion of a geographically widespread clonal lineage and nosocomial origin.fusarium oxysporum is a phylogenetically diverse monophyletic complex of filamentous ascomycetous fungi that are responsible for localized and disseminated life-threatening opportunistic infections in immunocompetent and severely neutropenic patients, respectively. although members of this complex were isolated from patients during a pseudoepidemic in san antonio, tex., and from patients and the water system in a houston, tex., hospital during the 1990s, little is known about their genetic relat ...200415528703
