The seroepidemiology of Helicobacter pylori and its relationship to chronic atrophic gastritis

Sitas, Frederick January 1990 (has links)
There were three main aims to this thesis: 1. to test whether infection with Helicobacter pylori was related specifically to chronic atrophic gastritis (CAG), a precursor of gastric cancer; and to measure the specificity and sensitivity of Helicobacter pylori antibody markers for detecting H.pylori infection of the gastric mucosa; and CAG; 2. to measure the distribution of H.pylori in relation to sociodemographic, dietary and lifestyle characteristics in non-clinical populations from Caerphilly (Wales), Italy, China, and Kenya; 3. to examine the relationship between H.pylori and gastric cancer. H.pylori was strongly associated with CAG and H.pylori antibody level was a sensitive and specific marker of both infection (84.8%, 92.7%) and CAG (71.4%, 90.9%). In Caerphilly and Italy, the prevalence of H.pylori increased steeply to 40-50% in those aged 45-54 years and levelled off in older age groups. In China, over 50% of those aged 35-44 were infected. In Kenya, almost all people studied between 18-30 years were infected with H.pylori. In Caerphilly, H.pylori infection was significantly higher in poorer socioeconomic groups, whilst in Italy, socioeconomic differences with regard to infection were in the same direction but not as pronounced. In Caerphilly, H.pylori infection was related to the number of the subject's siblings but not to the number of children or adults sharing the house of the subject. In Caerphilly, those infected with H.pylori consumed less vitamin C and more alcohol than those not infected. Those infected in Italy consumed more vitamin C but similar amounts of alcohol than those not infected. In China, smoking was inversely related to H.pylori infection. In China, a geographic correlation of +0.34 (2p = 0.02) was found between the prevalence of H.pylori infection (measured in 46 counties) and gastric cancer mortality. There was also a positive (but not significant) correlation with peptic ulcer mortality. No other type of cancer showed a significant association with H.pylori.

Genetic characterization and molecular evolution of the CAG pathogenicity island of Helicobacter pylori

Kouri, Kimberly. January 1999 (has links)
The perinuclear theca (PT) is a cytoskeletal structure that covers the nucleus of mammalian spermatozoa and is believed to have a membrane binding role. The objectives of this study were to analyze the protein composition of the mouse PT, to identify its major protein component, and to characterize this protein's transcriptional and translational origins during spermatogenesis. The PT was extracted from demembranated and acrosome-depleted mouse sperm heads by alkaline treatment. The protein profile of the PT extract was composed of several polypeptides of which a 15 kDa subacrosomal protein predominated and was found to be immunocross-reactive with a previously cloned 15 kDa PT protein of the rat (PERF 15) that belongs to a family of lipid binding proteins. A primer pair designed from rat PERF 15 cDNA was then used to screen a mouse testicular cDNA library by polymerase chain reaction (PCR). The deduced amino acid sequence obtained from the PCR product was almost identical to the testicular-specific rat PERF 15. Developmental Northern blots and in situ hybridization studies performed with riboprobes encoding the mouse PERF 15 cDNA revealed that mRNA levels were highest in round and early elongating mouse spermatids. Immunohistochemistry indicated that PERF 15 began to be expressed in the cytoplasm of mid-pachytene spermatocytes and appeared to reach maximum expression in the distal cytoplasm of late elongating mouse spermatids, long after transcriptional arrest. During the development of round and early elongating spermatids, the immunolabel became progressively concentrated over the anterior half of the spermatid nucleus suggesting a subacrosomal deposition of PERF 15 during this phase of mouse spermatogenesis.
