Herbal Medicinal

Since ancient times, various plants are being traditionally used, as medicine throughout the world. These plants are cultivated as well as collected from wild. Some important medicinal plants, which have source of wild, are difficult for collection. The best way to provide the plants needed for medicinal purposes is to cultivated rather than collecting them from wild. Now a days, some medicinal species are in risk of disappearing due to man-made and natural calamities. So there is need of conservation of medicinal plants to  maintain  sustainable development  by  protecting  and  using  biological resources  in  ways  that  do  not  diminish  the  world’s variety  of  genes , species, habitats  and  ecosystems. Medicinal plants can be cultivated by cutting, layering, grafting and budding and conservation mainly included activities like collection, propagation, characterization, evaluation and eradication,  storage  and  division. On the other hand, some modern techniques have been also established for the better growth and maintenance of medicinal plants such as In-Situ & Ex-Situ conservation, Germplasm technique, cryopreserpation technique, tissue culture technique. This review gives information about various cultivation methods to reduces misidentification and adulteration of medicinal herbs and also shows importance of modern techniques of conservation, management and sustainable utilization of medicinal plants for human health care. This information will definitely useful for quality of herbal medicinal products and reduced uncertain therapeutic effects.

In the Indian Himalayan Region, the use of medicinal plants is still a tradition continued by local people or ethnic communities and Traditional Medicine Systems play an important role in daily health care of poor people. The use of plants as medicine is slowly increasing in the developed world because they have minor or no side effects. The present study was conducted in Nargu Wildlife Sanctuary of Himachal Pradesh as the total dependency of the stakeholders on nearby forests for medicinal resources. In the present study, we reported 371 plant species that are used by the people in and around Nargu WLS as medicine. Distribution of maximum species (297 spp.) occurred between 1801-2800 m zone and only 40 species were present above 3800m. Of the total medicinal species recorded, 163 spp. were native to the Himalayan region and 24 spp. native to the Himalaya and other biogeographically regions. Rests (184 spp.) were non-native. The most frequently cured disease category (108 spp.) was gastrointestinal disease. Stakeholders of the Sanctuary and surrounding villages have rich indigenous knowledge of the use of medicinal plants to maintain their primary health. Traditional herbal remedies are important and effective because many traditional uses are scientifically proven through phytochemical and pharmacological studies. However, a large number of plant species remain untested for bio-efficacy and toxicity. Such tests may reveal novel remedies that have bioprospecting potential. Moreover, the study emphasizes the need for the conservation of such precious medicinal resource of the area by managing and conserving the natural habitats, checking unscientific exploitation and by applying in-situ and various ex-situ conservation methods.

Abstract Sediment community oxygen consumption (SCOC) rates provide important information about biogeochemical processes in marine sediments and the activity of benthic microorganisms and fauna. Therefore, several databases of SCOC data have been compiled since the mid-1990s. However, these earlier databases contained much less data records and were not freely available. Additionally, the databases were not transparent in their selection procedure, so that other researchers could not assess the quality of the data. Here, we present the largest, best documented, and freely available database of SCOC data compiled to date. The database is comprised of 3,540 georeferenced SCOC records from 230 studies that were selected following the procedure for systematic reviews and meta-analyses. Each data record states whether the oxygen consumption was measured ex situ or in situ, as total oxygen uptake, diffusive or advective oxygen uptake, and which measurement device was used. The database will be curated and updated annually to secure and maintain an up-to-date global database of SCOC data.

AbstractChemical Vapor Deposition of Si1-x Gex – films on Si (100) and of polycrystalline Si1-x Gex, layers on SiO2 – coated substrates have been performed at a pressure of 200 Pa in the temperature range of 500°C – 800°C, correspondingly. To observe the growth process and to characterize the growing thin films at deposition conditions an optical reflection interferometer (PYRITIERS) has been used. Comparing the data obtained at growth temperature with ex- situ measurements by spectroscopic ellipsometry the temperature dependence of optical constants of SiGe films have been evaluated. The reflectivity measurements during the deposition process allow to study the quality of the heteroepitaxial film, even in the initial stage of epitaxial growth.

Abstract Natural swimming pools (NSP) have become more popular in the past 20 years, both for private and public use, but their hygienic status remains a matter of discussion. Elimination rates in NSP are well defined for Escherichia coli, enterococci and Pseudomonas but a lack of knowledge exists regarding elimination rates in NSP concerning the parasitic protozoans Giardia and Cryptosporidium. First studies indicate that in-situ zooplankton filtration proved to reduce these protozoans efficiently: the in-situ elimination of Cryptosporidium is dependent on the population of zooplankton. In the 50% percentile the elimination rate is four times faster than in the chlorinated pool. The ex-situ elimination of Cryptosporidium in an NSP is approximately 10% faster than in a chlorinated pool. In ex-situ treatment of NSP the elimination rate reached 2 log-steps versus 1 log-step in chlorinated pools. For the further development of NSP for the best possible hygiene and health status some elementary questions, stated in this paper, will have to be solved in the next years or decades. This work describes the in-situ (water treatment inside the pool) and ex-situ water treatment (water treatment via external water treatment plants) of NSP, and the influence of zooplankton in existing NSP on the elimination rate of Cryptosporidium and Giardia.
