  • Ayurveda: Healing in a Natural Way ( 2771 reads)   

    In India, drugs of herbal origin have been used in traditional systems of medicines such as Unani and Ayurveda since ancient times. The Ayurveda system of medicine uses about 700 species, Unani 700, Siddha 600, Amchi 600 and modern medicine around 30 species. Medicinal plants antioxidant activity is mainly due to the presence of secondary metabolites. Based on their biosynthetic origins, plant secondary metabolites can be divided into three major groups: flavonoids and allied phenol and polyphenolic compounds, terpenoids and nitrogen-containing alkaloids and sulphur-containing compounds. - Category: Applications
  • Genome Sequencing Strategies ( 3702 reads)   

    Sequencing a genome is an enormous task. It requires not only finding the nucleotides sequence of small pieces of genome but also ordering those small pieces together into the whole genome. In 1975 Frederick Sanger developed a technique which was most widely used for DNA sequencing. He used dideoxynucleotide triphosphate (ddNTPs) in DNA synthesis. Recently automated system for DNA sequencing has been developed. Where ddNTPs are labeled with fluorescent dyes, each of different colours which are scanned by a detector and sequence is determined from the order of colour formed in band on gel. - Category: Bioinformatics
  • Bioenergy: Natural Sources of Energy ( 1875 reads)   

    The future of energy generation is Bioenergy. Biomass is a unique source of renewable energy as it can be provided as solid, gaseous or liquid fuel and can be used for generating electricity, transport fuels, as well as heat. Several traditional crops that are grown for food and other uses can also be used to produce bioenergy, primarily as Biofuels. - Category: Applications
  • Western Ghats - The Pride of India Flora ( 2204 reads)   

    The Western Ghats, an area of rich biological wealth and also exhibiting high degree of endemism, comprises the major portion of the Western Ghats, one of the 34 global biodiversity hotspots for conservation identified by the Conservation International. - Category: Agriculture
  • Marker-Assisted Backcrossing (Single and Multiple Genes) ( 2147 reads)   

    Genomics assisted crop improvement (GACI) offers a wide range of opportunities to identify major loci influencing the target traits and to select plants with the desirable combination of alleles with marker assisted selection (MAS), marker-assisted backcrossing (MABC) or marker-assisted recurrent selection (MARS). Marker-assisted selection is based on marker information only (pure MAS) or on index of marker plus phenotypic data (combined MAS). In both methods, markers can only lead to gametic phase disequilibrium exists between the marker loci and their pertinent QTL. - Category: Agriculture
  • Control of Viruses Infecting Crops and Plants ( 1849 reads)   

    Plant viruses and virus diseases have been studied for more than 100 years and many measures have been given to their control. This has been difficult to achieve because of the lack of any effective means of curing virus infected plants. Chemotherapy, thermotherapy and meristem tip culture is successful, but they cannot be used on a large scale. The main approach has been to prevent or delay virus infection or to decrease its effects. - Category: Agriculture
  • Microbe Used as Tool for Insect Pest Management ( 1900 reads)   

    Agriculture has been facing the destructive activities of numerous pests like fungi, weeds and insects from time immemorial, leading to radical decrease in yields. Pests are continuously being introduced to new areas either naturally or accidentally - Category: Agriculture
  • Crop Improvement Through Somaclonal Variation ( 5809 reads)   

    Somaclonal variation is defined as genetic and phenotypic variation among clonally propagated plants from a single donor clone. Somaclonal variation caused by the process of tissue culture is also called tissue culture induced variation to more specifically define the inducing environment. Somaclonal variation can be manifested as either somatically or meiotically stable events. Somatically stable variation includes phenotypes such as habituation of cultures and physiologically induced variation observed among primary regenerants. - Category: Agriculture
  • Developing Nutraceuticals From Plants ( 2526 reads)   

    In the last few years, there has been an increasing interest towards the search and characterization of new nutraceuticals from natural sources able to provide some additional benefits for human health like antioxidants, anti inflammatories, antihypertensive, hepatoprotective, antithrombotic antiviral and anticarcinogenic activities. Owing to their safety and potential nutritional and therapeutic values, nutraceuticals have attracted considerable interest. Supplements are products derived from natural sources which are included with the diet with ingredients like vitamins, minerals, amino acids, but without any therapeutic effects. - Category: Applications
  • Transgenic Plants in Production of Enzymes, Therapeutic Protein and Antibodies ( 5183 reads)   

    Transgenic plants resistant to pests, diseases and herbicides, tolerance to environmental stress (drought, temperature and salinity), improved nutritional value, composition, flavor and storage ability are being generated in an increasing number of agronomically important crop species. Transgenic plants have significant potential in the Bioproduction of complex human therapeutic protein due to ease of genetic manipulation, lack of potential contamination with human pathogens, conservation of eukaryotic cell machinery mediating protein modification and low cost of biomass production. - Category: Applications
  • In Vitro Micropropagation and Phytochemical Study of Tinospora Cordifolia ( 2730 reads)   

    Early micropropagation study of Tinospora cordifolia. Micropropagation is widely used technique for the regeneration of whole plant through tissue culture. This has become one of the most beneficial ways to produce species that are difficult to propagate by conventional methods. - Category: Biotech Research
  • A Foresight on Diabetes and Drugs Produced ( 1832 reads)   

    Diabetes Mellitus is a chronic metabolic disorder characterized by Hyperglycemia caused by defective insulin secretion, resistance to insulin action or both. An alternation of lipid and protein metabolism also causes defect in action or secretion of insulin. - Category: Healthcare
  • Marine Organisms: A Wide Source for Biologically Active Compounds ( 2542 reads)   

    Marine ecosystem is rich source of both biological and chemical compounds which are widely being used in pharmaceutical, cosmetic, nutrition supplements, molecular probes, enzymes and agricultural chemicals. - Category: Biology
  • Biofuels - A Solution for Non Renewable Sources ( 2821 reads)   

    Biofuels provides market for excess production of vegetable oil and animal fat, decreases country dependence on imported petroleum, reduce global warming due to closed Carbon cycle, reduces substantial amount of carbon monoxide, unborn hydrocarbon emitted from diesel engines. - Category: Applications
