The Mount Himalaya sitting as the crown of Indian subcontinent could be world's one of the most important land for study which remains to be understood and discovered a lot. The Indian Himalaya studded with human habitation ranging from Western Kashmir valley to the eastern Tip of Nagaland of North east India is rich in natural resources, floral and faunal population since yore. The greatness and rich resources of Mount Himalaya have been elaborately written in ancient Indian Literature in various dimensions. Understanding of this precious wealth, its use for mankind, conservation and sustainable use needs a thoughtful and continuous research on Himalayan ecosystem, its resources and utilization for welfare of world civilization. In recent time natural disasters and calamities in part of Himalayan zone created concern among the Government Policy makers, Non Governmental Organizations and Scientific community. An integrated approach of research in Engineering, Technology and Basic Science could bring answer for the conservation of Himalayan ecosystem that is the need of the hour of today's civilization. With increasing population, need of land as well as other domestic requirements has been increased obviously among the common people. Nature has given sufficient matter for their need. Justified and wise use of these resources is must for posterity. When, many communities across the world suffer from lack of potable drinking water, mount Himalaya has given these resources more than enough for us.
Government of India has given special attention for development of non conventional energy sources like, wind energy and solar energy for nation development. In such initiative, hydropower river dams in loose soils could be ether less prioritized or avoided. Carrying capacity of the ecosystem must be analyzed and need to be implemented accordingly.
The natural disasters like excessive flood, rain fall, cloud bust causing land slide has lead to suffering of common people. It is believed; such suffering could be either neutralized or minimized with a plan approach of infrastructure development, human settlement, development of agricultural land and practice as well as other ecofriendly measures. In India, Mount Himalaya is attached with the life of entire subcontinent. Monsoon, rainfall, temperature; over and above the deep root of Indian philosophy of life has been originated here. The great Indian saints have explained the Himalayan resources in different forms. Passing thousands of years, the modern research needs a different look to this Mountain range creating a base level database for future planning and posterity.

Abstract: In our fast paced environment, modern technology and chemical based medicine dominates the scene of medical world. Medical breakthrough happens every second as we speak and cure for previously untreatable conditions become feasible. However, consumption of chemical based medicines comes with a number of side effects. As a result, many have moved back to using plant based preparations and concoctions which come with little or no side effects. Hibiscus sabdariffa is one such plant that has been increasingly becoming popular due to its wide range of applications. Hibiscus sabdariffa is known by different names all over the world like roselle, red sorelle, Jamaican sorelle, sorelle, Indian sorelle etc. It is mostly found in Asia, Australia and Africa and consumed in different forms. It has been used traditionally as beverage served hot and cold, as flavouring and colouring agent in the food industry, and as herbal tonics. Hibiscus sabdariffa extracts showed antiseptic, aphrodisiac, astringent, cholagogue, demulcent, digestive, diuretic, emollient, purgative, refrigerant, resolvent, sedative, stomachic, tonic, antibacterial, emollient, sedative, anti-oxidant, anti-inflammatory, renal/diuretic effect, anti-cancer, anti-diabetic and antihypertensive effects among others. Because of its extensive range of traditional applications and effects on all the above medical conditions there is an enormous need for further investigation on this species.

Abstract: Notch signalling is an intercellular signalling mechanism that belongs to a family of four highly conserved transmembrane proteins. Its core transcriptional regulator RBPJk serves as a molecular centre for interactions with corepressor or coactivators, which inhibit or promote transcription, respectively. It is the main protein that control the expression of the target proteins involved in cell fate decisions by mediating signalling from Notch. Notch signalling pathway is an evolutionarily conserved signalling system that has been proven to be crucial for cell fate specification and embryonic development of all metazoans. Therefore, mutations or complete loss-of-function of Notch, RBPJk, and associated genes may effects on embryonic development or sometimes also results in embryonic death. In the present study, we reviewed the previous literatures for the better understanding of the RBPJk dependant notch signalling role in the embryonic development of the mice.

Abstract: The extraction of essential oil for its analysis and anti-microbial study has been in practice from so many years. The present work in Mentha arvensis L. for its anti-bacterial activity using bioautographic technique is for the first time. The essential oil extracted from Mentha arvensis L. was investigated for its antimicrobial activities against Aspergillus niger, Klebsiella pneumoniae and Escherichia coli. The essential oil extracted from the sample was analyzed using GC-MS technique to find out the presence of constituents. There are 72 identified bioactive molecules were identified in which menthol was present predominantly followed by isomenthane, menthol acetate and D-Limonene. The sensitivity of the chemical compounds against the microorganisms was determined by the bio-autographic assay. The oil exhibited maximum zone of inhibition as anti-bacterial agent against Klebsiella pneumoniae and Escherichia coli followed by as anti-fungal agent against Aspergillus niger. The anti-microbial activity could be due to the combined activity of the compounds present in the oil mixture extracted from the sample.

Abstract: The planet Earth is hospitable and fit for human habitation, mainly because of its average temperature of 150C which is due to the presence of Polar Regions. Though, technically both poles are 'similar', due to the geographical position of Arctic, where northern sea is surrounded by land mass, human habitation, industries, usage fossil fuel for various activities etc., compared to Antarctica, the temperature of Arctic region is increasing significantly at a faster rate than ever before resulting in melting of polar ice. While, at Antarctica due to geographic position, where the icy continent is surrounded by marine water, non-human habitation, no vehicular traffic, industries etc., melting of ice is much slower. However, Albedo effect is becoming dangerously alarming. This also contributes to rise in global temperature and thus leading to climate change. Added to the above, anthropogenic activities like uncontrolled fishing including whale in both northern sea and southern sea causes serious concerns.
