Gross pollutants are the primary targeted pollutants in urban catchment management for urban water quality improvement as well as mitigation of flood. Apart from aesthetically unattractive because of its visibility, gross pollutants also contributes to degradation of river water quality and loss of aquatic habitat as it carries harmful pollutants such as oxygen demanding material, hydrocarbons and heavy metals. This study analyzed trend of gross pollutant generated from two urban residential areas located in Selangor, Malaysia. The median value of gross pollutant load obtained from the Amanah Apartment and Bandar Botanic are 347.41 kg/ha/year and 32.46 kg/ha/year, respectively. Relationship between gross pollutant wet load with rainfall depths was derived using regression equation. A significant trend of increasing gross pollutant wet load into drainage system with increasing rainfall depth was observed. The behavior of pollutant load is related to the one observed in Australia.

Heat stress is one of the main reasons for reproductive performance decrease in cattle, resulting in severe economic losses. The aim of this study was to evaluate the effect of heat stress during maturation, fertilization and development of in vitro produced bovine embryos. Cumulus oocyte complexes (COCs) were obtained by follicular puncture from slaughterhouse ovaries and after identification, were divided into four groups: control (CG), exposed 1 (EG1), exposed 2 (EG2), and exposed 3 (EG3). The oocytes of the group CG and CG3 were cultured at 38°C and the oocytes of group EG1 and EG2 were cultured at 40°C during the maturation period (24 hours at 5% CO2 in air). After the maturation period, oocytes of group CG, EG1, EG2, and EG3 were fecundated with frozen thawed semen. The oocytes of CG, EG2 and EG3 groups were cultured at 38°C, and the group EG1 was cultured at 40°C (18 hours at 5% CO2 in air). After that, the CG and EG2 groups were cultured in SOF at 38°C and the groups EG1 and EG3 at 40°C during embryonic development. The embryos were evaluated for cleavage, morula and blastocyst rates by optical microscopy. In control (CG) and EG3 groups, the oocytes showed uniform expansion of cumulus cells, classified as moderate to high, with brown color and uniform appearance of the ooplasm. In the oocytes exposed to 40°C (EG1 and EG2) we observed a decrease in the expansion of cumulus cells, and the same showed rounded appearance and retraction of the ooplasm with dark coloration. The control group (CG) had 68.23% ± 2% of cleavage, 50.16% ± 2% morulas, and 43.28% ± 1% blastocysts. Whereas the EG2 had 31.46% ± 2% cleavage, 35.64% ± 2% morula, and no blastocysts development. The EG3 had 3.7% ± 2% cleavage, and no embryo production. These data suggest that in all stages of exposure to heat stress, the embryos and the gametes are susceptible, leading to a decrease in embryonic development.

Economic evaluations in gastroenterology in Brazil: A systematic review

引用

World Journal of Gastrointestinal Pharmacology and Therapeutics 2016年第1期7卷 162-170页

AIM: To systematically review economic evaluations in gastroenterology, relating to Brazil, published between 1980 and 2013. METHODS: We selected full and partial economic evaluations from among those retrieved by searching the following databases: MEDLINE(PubM ed); Excerpta Medica; the Latin American and Caribbean Health Sciences Literature database; the Scientific Electronic Library Online; the database of the Centre for Reviews and Dissemination; the National Health Service(NHS) Economic Evaluation Database; the NHS Health Technology Assessment database; the Health Economics database of the Brazilian Virtual Library of Health; Scopus; Web of Science; and the Brazilian Network for the Evaluation of Health Technologies. Two researchers, working independently, selected the studies and extracted the data. RESULTS: We ide nt if ie d 535 he alt h e c onomic evaluations relating to Brazil and published in the 1980-2013 period. Of those 535 articles, only 40 dealt with gastroenterology. Full and partial economic evaluations respectively accounted for 23(57.5%) and 17(42.5%) of the 40 studies included. Among the 23 full economic evaluations, there were 11 cost-utility analyses, seven cost-effectiveness analyses, four costconsequence analyses, and one cost-minimization analysis. Of the 40 studies, 25(62.5%) evaluated medications; 7(17.5%) evaluated procedures; and 3(7.5%) evaluated equipment. Most(55%) of the studies were related to viral hepatitis, and most(63.4%) were published after 2010. Other topics included gastrointestinal cancer, liver transplantation, digestive diseases and hernias. Over the 33-year period examined, the number of such economic evaluations relating to Brazil, especially of those evaluating medications for the treatment of hepatitis, increased considerably. CONCLUSION: Further studies are needed in order to ensure that expenditures on health care in Brazil are made as fairly and efficiently as possible.
