Handling a Virus Essay Example | Topics and Well Written Essays - 500 words

Handling a Virus - Essay Example B cells are also a part of the immune system but are produced in the bone marrow of the subject thus the letter B is used to denote them. Millions of variations of these cells are produced by humans and they circulate the body to produce antibodies once they are activated. A B cell has to come across its respective antigen and on the reception of a chemical signal from a T cell it can change itself to create an immune response. Knowing that HIV enters the body to inject macrophages and CD4+ T cells through glycoproteins on the surface to the receptors on other cells shows us that the Virus is attacking the very cells which could possibly envelop and destroy it (ADARC, 1999). Therefore, we would have to seek out ways in which certain T cells or B cells could be created which recognize what the virus actually is instead of simply attaching themselves to the virus to be destroyed. Since the creation of these T cells requires research on the virus itself, we would require live as well as dead samples of the virus that could be used on various mammals to see how their bodies respond to the virus and to see if any particular cells are generated by the subject which could lead to a cure for the virus in the shape of a vaccine. The surface point which would be a good target for the researchers could be the glycoprotein gp120 that normally connects to healthy cells in order to affect and infect them.

Rewrite - Case Study Example The protection also encompasses biodiversity conservation. 2. It fosters the process of furnishing the economic earnings to country, the region, and the local community. In essence, the protected area provides resources for conservation. 3. It provides financial resources for the conservation of other protected natural areas lacking tourism perhaps because they are unknown or because of their fragile ecological balance. 4. It can make protected areas more profitable thus encourages government or private investment in the establishment of other equally protected areas. 5. It can contribute to conservation if used as a tool of environmental education that sensitizes visitors so they can learn to conveniently value Nature, and respect not only the area they visit but also any other natural area. 6. It gives local communities alternatives to extractive activities that damage the ecosystems and endanger the natural resources. 7. It can help conservation process in other countries that emu late the success in the neighboring countries. Objectives of the Study: I. To secure and maintain the habitat and conditions necessary to protect significant species, groups of species, biotic communities or physical features of the environment where these require specific human manipulation for optimum management II. To facilitate scientific research and environmental monitoring as primary activities associated with sustainable resource management III. To develop limited areas for public education and appreciation of the characteristics of the habitats concerned and that of the work of wildlife management; IV. To eliminate and prevent exploitation or occupation inimical to the purposes of designation V. To deliver such benefits to people living within designated areas in line with the objectives of management Farwa MPA The Farwa MPA is located on Latitude 33Â ° 04' N and Longitude at 11Â ° 50' E to 33Â ° 08' N and 11Â ° 32' E (Approx) from Abu- Kamash in the east to the Tunisia n border in the west. It consists of Farwa lagoon, the largest lagoon on the Libyan coast that covers an area of 32 km2. The Farwa MPA, particularly Farwa lagoon, has meadows of Posidonia and Cymodocea sp., owing to certain economically significant species (shrimp, sponges, and fishes) as well as some endangered species that essentially make it an important area for larva and juvenile protection. In the biodiversity of Farwa MPA it is arguably easier to distinguish several economically important species and certain endangered species. Thus, it is imperative that this area gets adequate protection. The utmost altitude of the land on both sides of the lagoon is about 2-3 m (Sand type). Furthermore, the mean annual temperature varies from one month to another owing to the recent closing of the east side of the lagoon. The minimum mean temperature in winter is 10? C whilst the maximum mean temperature in summer is 27?C. The prevalent direction and speed of wind is largely NW and NNW. Ho wever, a hot southern wind sometimes blows from the Sahara. The Meteorological conditions of the region are those of the western part of Libyan coast. In such conditions, the winter season extends from November to April and is normally very cold and rainy with unstable winds blowing from different directions. The summer season (June to September) is rather hot and dry. The wind is more stable N and NW. Incidentally, spring and autumn are very short transitional periods. The lagoon is separated from the sea by some 11-km
