Like other zonitid snails, the species is small (10 mm in width) with a thin shell; its distribution ranges from the Appalachians to the southwestern Gulf Coast. Like many land snails, little is known about the biology of V. demissus, and its conservation status remains unstudied. Using a population from Seabrook, Texas, the morphology, reproductive behavior, and gut microbes of V. demissus were described in order to broaden the understanding of this land snail species' life history. Shell morphology data were consistent with those reported previously, while the mean shell required 4.6 N to crush. Reproductive behavior was witnessed between a single pair of individuals, who simultaneously probed one another with their dart apparatuses. In the laboratory, V. demissus laid over 300 small (1.5 mm) eggs, and the growth of twenty hatchlings was followed for at least ten weeks. Gut microbes were dominated by Mycoplasma, Paenibacillus, and enteric groups. These data fill in existing gaps regarding the biology of V. demissus. Future studies on the species should include additional populations from across its range, controlled breeding and rearing experiments, and finer-scaled microbial analysis to distinguish between natural gut flora and ingested microbes.","PeriodicalId":54431,"journal":{"name":"The Texas Journal of Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69517715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The renin-angiotensin system (RAS) plays an important role in volume balance by maintaining blood pressure in marine and seawater acclimated euryhaline fish, but little is known about the RAS in FW adapted fish. The purpose of the present study was to first determine if the FW channel catfish (Ictalurus punctatus), demonstrates evidence of a functional RAS. Channel catfish (n = 6) were implanted with a catheter in the dorsal aorta to measure dorsal aortic pressure (PDA) and infuse drugs. Infusion of [Asn1,Val5,Asn9]-angiotensin I (ANGI) at 100, 400, and 1000 ng/kg significantly increased PDA in a dose dependent manner (P < 0.05). Pretreatment with 2 mg/kg of the angiotensin converting enzyme inhibitor, Captopril (CAP), essentially eliminated the pressor response to the highest dose of ANGI (P < 0.05). Finally, infusion of 400 ng/kg [Asn1,Val5]-angiotensin II (ANGII) significantly increased PDA from baseline (P < 0.05). The results suggest that channel catfish appear to have an operational RAS and may serve as a suitable model in which to study the role of ANGII in blood pressure regulation in FW adapted fish.","PeriodicalId":54431,"journal":{"name":"The Texas Journal of Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46599174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the potential of radiant catalytic ionization (RCI) as a food decontamination technology through its reduction of inoculations of these bacteria on representative food items (apples, cantaloupes, and spinach). RCI exposure resulted in ≥99% reduction in the recovery of these bacteria within a 90-min exposure, with two exceptions (E. coli and S. typhimurium inoculated on cantaloupe: 94% reduction; 88% reduction, respectively). When E. coli, L. innocua and S. typhimurium were inoculated onto apple slices, the percentages remaining after exposure to RCI for 0, 30, 60 and 90 min were: 100, 2, 0, 0; 100, 30, 9, 0.01; and 100, 21, 0.004, 0.02, respectively. When E. coli, L. innocua and S. typhimurium were inoculated onto the rough outer skin of cantaloupes, the percentages remaining after exposure to RCI for 0, 30, 60 and 90 min were: 100, 19, 15, 6; 100, 9, 10, 1; and 100, 24, 22, 12, respectively. When E. coli, L. innocua and S. typhimurium were inoculated onto spinach leaves, the percentages remaining after exposure to RCI for 0, 30, 60 and 90 min were: 100, 16, 0.001, 0.002; 100, 19, 11, 0.005; and 100, 0.007, 0, 0, respectively (SE = ± 0.1 maximum).
