neutralizing antibody and non neutralizing antibody. When the same individual is infected with different dengue serotype, DHF or DSS results. (For example, he is infected with DENV 1 and then re infected by DENV2). This is because the virus infects the body cells following the general pathogenesis (See under Pathogenesis of Dengue Fever) and another pathway is the ADE mechanism. The ADE mechanism is nothing but the non neutralizing antibody will ‘help’ the virus to gain entry into the cell (Figure 4).
Q1. Entomotoxicology is the use of insects on decomposing corpses to determine and quantify the drugs which had been consumed by the individual prior to their demise. According to Campobasso (2004), as the maggots feed on the corpse, they consume the drugs available in the body, which can affect their growth or complicate their life cycle. He describes how maggots from different corpses which had been proved to have different amounts of drugs such as morphine varied in their development cycle and general characteristics (Campobasso, 2004). This claim was further supported by De Carvalho (2012) in which the study had shown that the presence of morphine in the maggot body would cause the acceleration of its development.
HISTORY The development of dentistry during the 19th century in combination with the germ theory of disease had a direct effect on the practice of dentistry. Irrigation in 19th century Literature from this period mostly contained numerous empirically based recommendations for a variety of rinsing agents and medicaments, such as pulp extirpation under a pool of oil of eucalyptus and cloves was advocated, the rationale being that these oils would penetrate the canal as the nerve was removed. Arsenic was introduced by Shearjashub Spooner et al (1836)4 to destroy the nerves of the teeth without causing pain. However, some cases of fatal consequences were reported due to the use of Arsenic and daily dressing with thorough canal irrigation was
The movie outbreak starts out in the year 1967 located within the Motaba river valley, Zaire, where the village located there is suffering from a very contagious virus that has a 100% mortality rate. The United States military is there to see the destruction that the virus has caused the villagers within the Motaba river valley. The military decides that they need to firebomb the village to stop the further spread of this dangerous virus to other parts of Zaire. The two military doctors that order the firebomb are Brigadier General Billy Ford (Morgan Freeman), and Major General Donald McClintock (Donald Sutherland) who is there seeing, and reporting the devastation that the virus has caused to their superiors back in Washington D.C. The movie then flashes forward to modern day, which is 27 years later from the discovery of the virus from the Motaba River Valley in Zaire.
In this article, it will be written about how diseases spread, how we make them as medicine, types of them and how some help us.

Malaria can occur all the year around but the number of cases increases during the monsoon season. Cause: The warm humid weather and stagnant water of the monsoon provides an ideal breeding ground for mosquitoes. The female anopheles mosquitoes which are infected by the malaria parasite, spread malaria when they bite their victims during the night. A person may also get malaria fever if they receive infected blood during a

Even the regular detergents are chemical substances which could contaminate the environment. A careful examination of the labels of detergent merchandise could verify that they include a ramification of doubtlessly unsafe chemical compounds. TYPES OF ORGANIC POLLUTION **DDT Dichlorodiphenyltrichloroethane, DDT, is an insecticide that acts as soon as extensively used on agricultural vegetation to tackle bugs that transmit sicknesses along with malaria and typhus. DDT enters the meals chain whilst used as insecticides. It can then stay within the soil for years.
Use netting over strollers, playpens, etc. The pregnant women should take care to avoid exposure to the repellents. Non herbal insect repellents Fig: 10. Insect repellent spray • N, N-Diethyl-meta-toluamide, which is called as DEET, it is the most common active ingredient in insect repellents. It is yellow oil which can be applied to the skin or clothing and provides protection from mosquitoes, ticks, fleas, leeches, and many biting insects.
Survey of the Anti-pilling Treatment of Polyester/Cotton Fabric Abstract: Pilling is caused by a natural fibre migration from the yarns to the fabric surface as the fabric rubs against itself, another fabric, or even the skin. The main aim of this research is to investigate the effect of anti-pilling treatment on polyester/cotton fabric by using the anti-pilling agent. The objectives of this research are to apply the anti-pilling agent on polyester/cotton fabric with various concentrations and to analyse the effects of anti-pilling treatment on polyester/cotton fabric. Physical properties of the anti-pilling treated fabric such as air permeability, fabric stiffness, breaking strength and crease recovery are tested and analysed. According
