Investigations on malaria outbreaks and role of sibling species complex of principal rural malaria vector Anopheles culicifacies were carried out in villages in north Karnataka, India from 1997 through 2014. Information regarding densities, resting and breeding habitats of malaria vectors prevalent in the area was also generated so as to formulate an appropriate vector control strategy. The Slide Positivity Rate (SPR), Slide Falciparum Rate (SFR) and Pf proportion was 43.1%, 35.9% and 83.3%, respectively. Three sibling species A, B, and C of An. culicifacies were found sympatric with cumulative percent composition of 63.7, 28.2 and 8.1, respectively. Per man hour and per structure densities of An. culicifacies, An. culicifacies and An. culicifacies varied from 0 to 27.5 and 0 to 56.0, 0 to 0.5 and 0 to 7.0 and, 0 to 2.5 and 0 to 7.5, respectively. The proportion of semi-gravid and gravid females was more as compared to fully fed and unfed females which indicated that most of the females rested indoor. Streams/river, wells, seepages and irrigation tanks are the major habitats supporting breeding of An. culicifacies. Integrated vector managements by indoor residual spraying of effective insecticide as per national guidelines along with biological control methods especially use of larvivorous fish Gambusia affinis and Poecilia reticulate are suggested to control malaria in the area.

Objective: A comparative analysis on transmission of Helicobacter pylori in people who consumed food prepared in both hygienic and unhygienic conditions. Method: The study was carried out in 1000 people across India. The Ratio of Male: female was 700: 300 with age group ranging from 20 - 39. Three gastric biopsies were collected for identification of Helicobacter pylori. PCR (Polymerase Chain Reaction) amplification was done by using 16srRNA primers. Result: The analysis showed the prevalence of H. pylori as 70.8% in individuals frequently consuming food prepared under less hygienic condition (street vendor’s food) whereas 60% (less prevalence) in individuals consuming food prepared under hygienic conditions. Conclusion: The results showed that most of the food that we consume daily is not involved much in the transmission of Helicobacter pylori. The study also showed that the street vendor’s food is not directly involved in the transmission of this bacterium. The unhygienic preparation of food and poor personal hygiene play a vital role in the transmission of these bacteria.

Indian coast harbors richly diverse and critical coastal habitats like coral reefs and mangroves. Mangroves form one of the most important ecosystems of coastal and marine areas. It safeguards the ecology of the coastal areas and provides livelihood opportunities to the fishermen and pastoral families living in these areas. In real sense, mangrove is the Kalpvriksh (divine tree which fulfills all the desires) for the coastal communities. The restoration and plantation of mangroves have received a lot of attentions worldwide. To assess the impact of mangrove plantation activities and to monitor the mangrove regeneration and restoration in various villages, a joint study under the Integrated Coastal Zone Management Project (ICZMP) was taken up by Gujarat Ecology Commission (GEC) and Bhaskaracharya Institute for Space Applications and Geo-Informatics (BISAG) in the Gulf of Kachchh, Gujarat State.?The major objective of this study was to monitor the increase in mangrove cover in coastal areas of Gulf of Kachchh using the Indian Remote Sensing Satellite data of 2005, 2011 and 2014. The mangrove regeneration was monitored using multi-temporal Indian Remote Sensing Satellite (IRS) LISS-III and LISS-IV digital data covering Gulf of Kachchh region. The multi-temporal IRS LISS-III data covering Gulf of Kachchh of October-2005, November-2011 and LISS-IV data of April-2014 was analyzed. The mangrove density and mangrove area in different talukas was estimated based on the analysis of IRS LISS-III digital data. The mangroves have been delineated based on the pink colour observed on satellite images and the area was estimated in the Geographic Information System (GIS) environment. The taluka or block-level mangrove areas were estimated and changes in the areas were monitored during the period of six years from 2005 to 2011. It was observed that the areas where mangrove regeneration activities were carried out with active participation of Community Based Organizations (CBOs), mangrove density as well as mangrove area have subst

We study the relation between monthly average counting rates of the cosmic ray intensity (CRI) observed at Moscow Neutron Monitoring Station, solar flare index (SFI) and coronal index during the solar cycles 22 and 23, for the period 1986-2008. The long-term behaviour of various solar activity parameters: sunspot numbers (SSN), solar flare index (Hα flare index), coronal index (CI) in relation to the duration of solar cycles 22 and 23 is examined. We find that the correlation coefficient of CRI with the coronal index as well as Hα flare index is relatively large anti-correlation during solar cycle 22. However, the monthly mean values of sunspot number, Hα flare index, and coronal index are well positively correlated with each other. We have analyzed the statistical analysis of the above parameters using of linear model and second order polynomial fits model.

Ulcerative colitis is considered frequent in majority of European and North American population and exceptional in most of the developing Asian countries. There is a dearth of reported data from South India on the incidence of the disease and its prevalence. Hence the present study was designed to estimate the prevalence of ulcerative colitis in a tertiary care hospital of Hyderabad, South India. The study population consisted of 157 Ulcerative colitis and 204 healthy subjects. All subjects were interviewed by means of a questionnaire for general demographical details and socioeconomic conditions, health related quality of life and history of UC. Patients were categorized based on disease severity;moderate: 95, and severe: 62 and disease manifestation: 73 (46.5%) pancolitis, 60 (38.2%) left-sided colitis and 24 (15.3%) had proctosigmoiditits. Disease prevalence was high in patients

Introduction: H. pylori is a primary pathogen isolated by Warren and Marshall in 1983. They called it as Campylobacter Pylori and in 1989 Goodwin et al. renamed it as Helicobacter pylori. Helicobacter pylorus is one of the responsible factors for causing gastritis, Peptic ulcer disease and is strongly associated with gastric carcinoma and gastric Malt lymphoma. Materials and Methods: In this study 300 biopsies were collected at Deccan College of Medical Sciences and Allied Hospitals, Hyderabad, India. Of these, 101 patients had peptic ulcer, 95 patients had gastritis and 4 had gastric carcinoma. A total of four gastric biopsy specimens were collected. One was used for culturing H. pylori, one for histological lesions and the remaining two one each from the antrum & corpus was collected in phosphate buffered saline for the DNA analysis. Results: Helicobacter pylori were isolated from many of the biopsies and the identification of Helicobacter pylori was confirmed in 200 biopsies with colony characteristics, Biochemical tests, and 16S rRNA amplification. The presence of VacA marker was detected by using appropriate primers. From the data obtained in our study, in a total of 169/200 isolates s1 region was found in 84.1% and s2 was found in 36/200 i.e. 18% of the isolates. In the middle region, m1awas found in 60/200 which was 30%, m1b was found in 60/200 i.e. 60% and m2 was found in 114/200 i.e. 57.1% of the isolates. Conclusion: Thus, VacA detection might be helpful for determination of which patients are at highest risk for severe clinical outcomes such as duodenal ulcer, gastric ulcer or gastric carcinoma and eventually, to define strategies for the treatment or prevention of H. pylori infection.

尽管社会经济和技术发展迅速,仍有大约1/4的世界人口依赖传统能源(如煤油、天然气、生物质废弃物、木柴、煤炭、动物粪便等)家庭使用。为了满足逐渐增加的能源需求,矿物资源储量正被大量开采,因此在矿物能源用尽前,需要寻找可替代能源。废弃物能量回收(Waste To Energy,WTE)是一种潜在可替代的能量来源,经济可行,环境友好。本研究综述了目前全球高效能源回收的WTE技术(包括焚烧、热解、煤气化、厌氧消化以及填埋产气)的选择方案,以及发达国家和发展中国家所面临的挑战。本综述基于发达和发展中国家的案例研究为评价WTE技术选择提供了一种整体框架。在发展中国家最常见的垃圾处理选择是非环保的废物填埋,而发达国家已经意识到WTE技术高效管理城市固废(Municipal Solid Waste Management,MSWM)的潜力。本综述可以帮助政策制定、实施机构以MSWM的思路理解城市固废高效管理的当前形势、挑战和阻碍。本综述得出WTE是一种潜在的新能源,将在一定程度上满足能量需求,确保高效管理城市固废管理。
