It is endemic to a part of the world known as “tsutsugamushi triangle.” This extends from Japan, China, Taiwan, South Koria, Nepal, Pakistan, Papua New Guinea, Australian states of Queensland and Northern New South Wales. In India, it has been recognized for several years and the disease widely spread all over the country. The severity of scrub typhus disease has been reported to be strain dependent in humans. Orientia tsutsugamushi strains have been examined by various research tools. PCR amplification and sequencing of 56-kDa antigen gene is one of the most advanced tool in identifying O. tsutsugamushi strains and genotypes. In the present review, English-language literature for reports of Orientia tsutsugamushi genotype diversity and distribution in India was searched using PubMed and Google Scholar databases. The search terms scrub typhus or mite typhus or tropical typhus or tsutsugamushi disease or Orientia tsutsugamushi or Rickettsia tsutsugamushiwere used in combination with the term genotypes or strains or serotypes. The result of present review revealed limited Information related to genotype diversity and distribution in the country. Understanding a more detailed regional genetic diversity is required in region-specific vaccine development strategies andsero-diagnostics tools.","PeriodicalId":21329,"journal":{"name":"Science & Technology Vision","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80574319","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}

In recent years, the incidence of autoimmune and other inflammatory diseases increase in developed and industrial regions. The entry of any infectious disease is challenged by the body immune system through various branch of immunity among which T-helper branches of immunity (Th1 and Th2) play at the fore-front. However, the uncurbed imbalance of Th immune response where a surge in Th1 (IFNγ and TNFα) over Th2 response is implicated to cause various autoimmune and inflammatory disorders. In general, parasitic helminth infection is fought by the body as up-regulation of Th2 branch of immunity by secreting inflammatory cytokines (Interleukins like: IL-4, IL-5, IL-9 & IL-13) thereby executing antibody-dependent cellular cytotoxicity (ADCC). In recent years, exciting evidences revealed that the uncurbed Th1 surge is brought to balance by administration of parasite or parasite extracts thereby alleviating the clinical manifestation of autoimmune and inflammatory disorders. This paper describes works that have been carried out to control various autoimmune and inflammatory disorders using parasite or parasite extracts.","PeriodicalId":21329,"journal":{"name":"Science & Technology Vision","volume":"76 5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89714131","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}

More and more techniques for efficient use of water are required throughout the world, especially in developing countries like India. The present study was conducted to analyse the quality of potable water sources use by the citizens of Aizawl district in the state of Mizoram, India. Number of samples was collected from surrounding areas of Greater Aizawl in pre cleaned polyethylene bottles as recommended in the WHO standards and recommendations. Various physico-chemical properties (pH, turbidity, total hardness, chloride, free chlorine, iron, nitrate and total dissolved solids) were studied. The samples were analyzed in the field using handheld meters for pH, turbidity, total hardness and TDS and were then also analyzed in the laboratory to confirm the field results. The other chemical parameters were tested in the laboratory using standard and recommended techniques. The pH values ranged from 6.48 to 7.54. TDS values ranged from 30 to 430ppm. Total hardness ranged from 30 to 60 mg/l. Chloride content in the samples was found to be between the values of 15.5 to 80 ppm. Iron and nitrate were found only in trace quantities in all the samples. In surrounding areas of the city, proper development of perennial springs would serve as the main source of water supply to the local population. Some samples which contained higher concentrations of chloride could have been contaminated from sewage water or waste water leakage. Other than that, the quality of water was within the limits of WHO standards.","PeriodicalId":21329,"journal":{"name":"Science & Technology Vision","volume":"162 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76989892","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}

We have studied the structural, electronic and magnetic properties of non-metallic element (B, C and N)-doped CdO monolayer based on spin-polarized density function theory within the generalized gradient approximation (GGA) as revised for solids by Perdew, Burke and Ernzerhof (PBE-sol). Substituting B, C and N in O site with one atom in CdO monolayer induces spin polarized localized states in the gap or near the valence band and exhibit local magnetic moments ~ 1 μΒ, ~ 2 μΒ and ~ 1 μΒ respectively. It is found that the magnetic states in these doped systems are associated with the difference between the electronegativity of the dopant and the anion in the host. Our study shows that non-metal doped CdO is a promising candidate for novel nano-materials for future applications.","PeriodicalId":21329,"journal":{"name":"Science & Technology Vision","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75673311","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}

Coleoptera (Gk. Coleos–sheath, ptera–wing) are the largest group of organisms at the order level and are comprised of beetles. They adapt to a wide range of environmental conditions and are widely distributed. The family Scarabaeidae which is included in the superfamily Scarabaeoidea is one of the largest families. They consist of about 27,800 species worldwide and are further divided into 16 subfamilies, 82 tribes and 94 sub-tribes. They are usually harmful or beneficial in nature with their size being large to small. The research on scarab beetles is necessary to understand their role as pest as well as their adaptation to different anthropogenic activities. Also, the diversified population of scarab beetles along with their similar characters makes it hard for researchers to identify them often leading to misidentification which is why a review is needed.
