The herpesvirus family includes some of the well-known pathogenic viruses such as herpes simplex, varicella-zoster, Epstein-Barr, and cytomegalovirus. Some of these viruses are believed to pose major risks in immunosuppressive post-transplantation therapies, while others have been associated with life-threatening diseases such as AIDS and various cancers (Bennett et al., 2001; Biswas et al., 2001; Labrecque et al., 1995; Vital et al., 1995). Examples of the 80 or more herpesviruses that infect...
Crude glycerol is the by product produced throughout the biodiesel production process. However glycerol produced at this stage is crude glycerol which is about 80% pure and contains other contaminants like methanol, water, salt and soap. Crude glycerol has approximately about 45% glycerol, 10-15% water and methanol, 10-15% salt, and 30% soaps by weight2. This crude glycerol is not a highly valued chemical so a purification process must be done to make the crude glycerol into useful glycerol...
The Ficus reticulata fruit mucilage is an edible fruit and its pulp is rich in mucilage. But there are no reports on isolation and characterization of Ficus reticulata fruit mucilage. Hence, the present study was designed to isolate, purify and characterization of Ficus reticulata fruit mucilage. Ficus reticulata fruit mucilage was extracted, purified and identified by official methods. The isolated mucilage was characterized for physical, chemical and flow properties. The mucilage was further...
I searched electronic databases such as EMBASE, Medline, Cochrane Library and NHS Database of Review of Effectiveness from 1998 to 2009. The main purpose of literature review was to identify all published articles in peer-reviewed journals and this articles reported that the clinical effectiveness of TNF α inhibitors such as infliximab, adalimumab and etanercept in rheumatoid arthritis patients who had previously been treated with at least one TNF α inhibitor or DMARDs or biologic...
Stem cell research is a controversial topic that has become a heated national debate. Researchers have found that embryonic stem cells can divide and regenerate. These embryonic stem cells can grow into many types of cells and tissues. Scientists believe that embryonic stem cells can have a positive impact in finding a cure for a wide range of diseases including Parkinson's disease, while conservative groups have compared the use of embryonic stem cells to abortion. This has prompted the...
There are four main factors which affect the rates of reaction these are listed below with a brief explanation of how and why this is possible There are many different factors which affect the rates of reaction and this is one of them the reason why temperature plays a part is because by increasing the temperature you are increasing the rates of reaction. The reason why temperature affects rate of reaction is because when you heat up the solution the particles within the solution move faster...
The apple is the pomaceous fruit of the apple tree, species Malus domestica in the rose family. It is one of the most widely cultivated tree fruits, and the most widely known of the many members of genus Malus that are used by humans. Apples grow on small, deciduous trees. The tree originated in Western Asia, where its wild ancestor, Malus sieversii, is still found today. Apples have been grown for thousands of years in Asia and Europe, and were brought to North America by European colonists....
Dilution is a process of making a weaker or a less concentrated solution. Substances which are highly concentrated can be problematic to carry out tests. For instance, when a blood sample is placed on a slide it would be difficult to count cells due to overlapping. As a result dilutions are carried out so that the cells will be more spread. Moreover a large amount of reagent would be needed to react with a highly concentrated substance. This is inadequate since large amounts of reagent would be...
Motivation can be defined as "the development of a desire within an employee to perform a task to his/her greatest ability based on that individual's own initiative". By examine the definition, one be capable of establish, motivation to be the level at which a worker resolve achieve a particular action for the corporation, a very important task for success. The definitions of motivation, lead an organisation to consider their workers will achieve their particular responsibilities...
Abstract- Ionic liquids are compounds of high interest for industry because of their attractive properties as solvents, but the water solubility of these compounds may lead to aquatic pollution and related risks. Experimental toxicity evaluation (Daphnia magna EC50) is a measurement of aquatic toxicity but there are theoretically over 1 trillion ionic liquids, which makes it necessary to estimate their properties by means of quantitative structure-activity relationships (QSARs). In this work, a...
