Miura et al., conducted an experiment, to examine the intake of green tea polyphenols renders LDL resistant to ex vivo oxidation in humans male volunteers were assigned the same dietary pattern. They were equally divided into two groups: control and tea. The tea group ingested 300 mg of green tea polyphenol extract twice daily. Plasma concentrations of lipids, ascorbate, α-tocopherol, and lipid peroxides did not change before and after the experiment in either group, but β-carotene...
In its natural state, blood is the most precious and personal substance in the world. Within the realm of cardiac surgery, transfusing donor allergenic blood products is becoming a thing of the past and heading in the direction of saving and preserving the patients own autologous blood. One's whole blood has natural healing abilities and homeostasis of which no other substance can emulate (Samolyk KA, 2009). Cellular composition of blood consists of three main elements. The...
Perennially frozen and glacierized high mountain areas react very sensitively to changes in atmospheric temperature (Haeberli & Beniston, 1998). As a consequence, since the middle of 19th century, i.e. since the end of the Little Ice Age, the glaciers in the European Alps have lost about 30 to 40% of surface area and ca. 50% of their original volume (Haeberli & Hölzle, 1995). Since 1980, an additional loss of this remaining ice volume was ca. 25% (Haeberli, 2005). Less visible but...
Hydrothermal synthesis is one of the numerous ways of producing ZnO nanoparticles. This research examines the use of this method for the production of ZnO nanorods. The method was found to have the advantage of simplicity and environmental friendliness over other ZnO nanorods production routes. To further enhance the suitability of the method for commercial purposes, synthesis was performed without the use of growth-assistive catalysts. Variation of the nanorods sizes was achieved by...
Introduction Ageing can be seen a progressive deterioration in the structure and function of the cells, tissues, organs and organ system in the body with advancing age. Aging damage occurs to molecules such as DNA, proteins, lipids and to cells and organs. Ageing is accompanied by impairment of physiological functions; this is known as senescence and is characterized by the declining ability to respond to stress, increasing homeostatic imbalance and increased incidence of pathology. This series...
INTRODUCTION:- Marine biotechnology is a multi-disciplinary and ever expanding field in world's leading technologies. Marine biotechnology encompasses the importance of marine resources to the world, either as the source or target to spread biotechnological applications. It refer not only utilization of living organisms to make a product or run a process, but also play key role in better understanding the life in ocean and help in conservation of marine species in a sustainable way. Marine...
Despite tremendous governmental, corporate and social awareness, and the concerted efforts to address its ethical implications, the use of animals as test subjects is still widely practiced today. In actuality, based on academic research trends, the focus on animal testing appears to have changed from whether it is ethical to why it continues to be a popular method for clinical experimentation. In other words, why does this practice continue to flourish, despite tremendous awareness of the...
This paper describes how polymerase chain reaction (PCR) can be used to determine if various food items have been genetically modified by detecting reporter genes. This study involved preparation of 1.25% agarose gel, and the preparation of the various food items for PCR. The food items analyzed in this study were chosen from fresh and processed food items to determine if PCR can detect genetic modification equally. Two different master mixes were used to determine genetic modification. ...
The inflammatory bowel diseases are chronic inflammation of the digestive tract. Serum Beta 2 microglobulin levels increase in all chronic inflammatory disease. This increase is linked to the severity and extant of inflammation. In the study we examined Beta 2 microglobulin serum levels in patients suffering from inflammatory bowel diseases, to assess the extent of the disease and the possible correlation between these serum levels and the activity of inflammatory bowel diseases. Methods: ...
The phenylchlorocarbene is formed after α-elimination of hydrogen chloride from benzal chloride when tBuO-.is introduced as base to deprotonate the proton on the benzylic carbon of benzal chloride. The anion formed after the deprotonation of benzal chloride loses a chloride ion spontaneously to form phenylchlorocarbene. A cycloaddition reaction will then occur between the acetylenic carbon of diphenylacetylene and phenylchlorocarbene to form the cyclic 3 member triphenylcyclopropenium...
