Abstract

The condition of hyperlipidemia can be described as high cholesterol in the blood (hypercholesterolemia), high triglycerides in the blood (hypertriglyceridemia) or it could be both. Hyperlipidemia is a major risk factor in the initiation and progression of atherosclerotic lesions, conditions such as coronary heart disease, ischemic cerebrovascular disease and peripheral vascular disease which leads high morbidity rate in developed countries. The present article gives different classes of anti-hyperlipidemics highlighting the pathophysiology of artherosclerosis, classification, side effects and therapeutic uses of antihyperlipidemics.

Keywords

Hyperlipidemia, Cholesterol, Atherosclerotic Blood Vessel.

Abstract

Chemoprevention agents can also identified by systematic evaluation of agents that acts at specific molecular targets with respect to cancer by using laboratory assay. The use of specific nutrients, other chemical compounds in the prevention of cancer is referred to as chemoprevention. Now a days, very less research work focusing on the effect of substrate bound elemental Se nanoclusters on cancer growth. The mechanisms by which nano selenium compounds inhibit tumor formation during the initiation phase of carcinogenesis have been explored in vitro. Selenium nanoparticles are very beneficial for treatment of cancer.

Keywords

Nanoselenium, Cancer Chemoprevention.

Abstract

The groundwater arsenic contamination in Bangladesh is a phenomenon of surface ero- sion, transportation and deposition in the form of Delta and ∼lood Plain. While dealing with such geomorphological units like Tableland, Flood Plain, Delta and Hill Tract in Bangladesh, we have found the possibility of having huge arsenic contaminattion free groundwater reservoir in selected areas in Bangladesh. The results presented are the outcome of our last 5 years, field survey analysing for arsenic of water of twentyfive thousand eight hundred ninetyseven hand tubewells in sixtyfour districts of Bangladesh comprising four existing geomorphological regions (a) Deltaic region (including coastal region), (b) Flood Plain, (c) Tableland and (d) Hill Tract. In this report, we will highlight (1) the area in Bangladesh where groundwater is not arsenic contaminated and the' possibility to use shallow hand tubewells as potential groundwater resource for drinking purpose and (2) arsenic contaminations scenario of deep tubewells (above 100 meters) all over Bangladesh and suitable depth in arsenic contaminated area to get safe water.

Abstract

The sediment succession in the Bay of Bengal (BoB) records the signatures corresponding to India-Asia collision, regional climate change, and erosional processes of both the Himalayan orogen and Indian subcontinent. The Bengal Fan-the world's largest submarine fan-has long been studied to understand the link between the Himalayan tectonics and Asian monsoon. But, lack of detailed information on corresponding signals hampered the understanding of related processes of tectonics, climate and erosion. The present study of long-streamer seismic reflection profile data and information from deep drill well logs in the western BoB has revealed two different phases of sediment deposition. In the first phase, until Oligocene- Miocene (∼23 Ma), Indian peninsular rivers discharged sediments to the BoB which accumulated at a rate ∼20 m/m.y. with an aberration of two fairly enhanced sediment pulses during the periods from 65 to 54 Ma and 34 to 23 Ma. In second phase, since 23 Ma, the Ganges and Brahmaputra rivers added huge volumes of sediments to the bay at variable rates ranging from 40 to >1000 m/m.y. A distinct increase in sediment discharge (∼140 m/m.y.) during the Oligocene-Miocene (∼23 Ma) together with the development of regional onlap unconformity and the start of turbidity system provide an important age marker corresponding to rapid exhumation of the Himalaya, which intensified the erosional process and commencement of Bengal Fan sedimentation. Further rise in the rate of sedimentation during the period 6.8- 0.8 Ma is coincident with the change in monsoon intensity, but surprisingly not in agreement with the decrease in sediment rate reported at ODP Leg 116 sites in the distal Bengal Fan. Here we provide wellconstrained ages for the commencement and growth of the Bengal Fan, which can serve as benchmark information for understanding the interaction between the Himalayan exhumation and Asian climate.

Keywords

Asian Climate, Bengal Fan, Continental Collision, Himalayan Tectonics, Ganges and Brahmaputra Delta.

Abstract

A number of medicinal plants are available which helps both in growth promotion and inhibition of different micro-organisms. Micro-organisms having capability to produce several diseases and also by secreting different enzymes which help our body to develop.

Different extracts obtained against each process like cold infusion, hot infusion, decoction and maceration were suitably diluted with doubled distilled water. Several different samples were prepared and marked as Papain extract, Combined extract, Combined extract with Papain, Mixed Extract and Mixed Extract with Papain. Different cell cultures of four different species of micro-organisms were used based on different dilution and type of extraction. They are applied to observe the growth promotion of those beneficial micro-organisms. The maximum growth was observed in case of those extracts obtained from hot infusion and decoction process.

Keywords

Microbial, Digestive, Ayurvedic.

Abstract

A voyage from Chennai across the Bay of Bengal takes one eventually to the Andaman Islands. But it was a different situation in the geologic past during the Late Cretaceous (80-68 m.y. BP). There was a chain of islands somewhere midway which currently lies as the buried 85E Ridge beneath enormously thick sediments discharged by the Ganges and Brahmaputra river systems.

Abstract

The leaves of Lippia alba (fam. Verbenaceae) were studied to fix the parameters for pharmacognostical standards. The results of organoleptic study offer a scientific basis for the use of Lippia alba which possesses characters like green colour, strong aromatic odour and aromatic taste. The fluorescence analysis under visible light & under UV light by treatment with different chemical reagents showed different colour changes. The presence of flavonoids, steroids, tannins, saponins and reducing sugars was confirmed during preliminary phytochemical screening.

Abstract

The geographical location of Kolkata, where the city now exists with a metropolitan population of over 15 million, was once on the verge of the continental margin and was also neighbouring the proto-ocean of the Bay of Bengal (BoB). As a consequence, most part of the present Bangladesh territory was under ocean water during the geological past.
