Effects of different corticosteroids on the immune system Research Paper

Effects of different corticosteroids on the immune system - Research Paper Example The glucocorticoids are used in replacement therapies for various inflammatory diseases, in severe allergic reactions such as asthma, in the management of some autoimmune disorders and in some cancers as well (Howland, Mycek, Harvey, Champe, & Mycek, 2006). The therapeutic role of corticosteroids has expanded since their first application for the treatment of reheumatoid arthritis in 1949 (Doan, Melvold, & Waltenbaugh, 2005). Different therapeutic corticosteroids are available for replacement therapies, and they play an important immunosuppressive role by mediating the adaptive and innate immune cells of our body. Cortisol is the basic and fundamental glucocorticoid produced in the human body. The three main functions for which corticosteroids are widely used therapeutically include their use as anti-inflammatory agents, for suppression of the immune system, and as a replacement therapy for replacing the hormones not produced at normal levels by the body (NHS Choices, 2013). The prod uction of cortisol reaches its peak during the early morning followed by a drop and then again a peak, relatively smaller, in the late afternoon. Cortisol has various body functions. It promotes the production of glucose and protein catabolism and the degradation of lipids by lipolysis. Cortisol increases the body’s resistance to stress by elevating the blood glucose levels, which helps in more energy production, and fighting stress situations such as cold, trauma, infections, fright, and bleeding. Cortisol also plays an important role in decreasing the blood cell levels which include eosinophils, basophils, monocytes, and lymphocytes. This particular action is important in the treatment of leukemia. The lowering of peripheral lymphocytes and macrophages also helps in mediating an anti-inflammatory action. Cortisol increases the production of growth hormone (Howland et al., 2006). The immunosuppressive action of corticosteroids is used in the treatment of many autoimmune diso rders such as inflammatory bowel disease, systemic lupus erythematous, and rheumatoid arthritis. Corticosteroids are also helpful in treating several renal autoimmune diseases such as nephrotic syndrome (Doan, Melvold, & Waltenbaugh, 2005). Numerous corticosteroid preparations are used for therapeutic purposes. Hydrocortisone is used as a topical preparation or in an injectable form. The injections are given to reduce inflammation in joints and tendons of affected individuals. Dexamethasone is used in acute conditions such as severe breathing allergic reactions, and is utilized mainly in the intravenous form. Prednisolone is used in several autoimmune conditions and allergic reactions and is available in suppository form, injections and as oral tablets. Fludrocortisone’s fundamental usage is for Addison’s disease, in which there is a deficiency of normal body steroid production (NHS Choices, 2013). Cortef contains hydrocortisone and is readily absorbed from the gastroi ntestinal tract. It has a wide variety of indications including rheumatic disorders, adrenal insufficiency, SLE, dermatological conditions such as psoriasis, seborrheic dermatitis, exfoliative dermatitis, allergic conditions such as asthma, serum sickness, rhinitis, drug hypersensitivity reactions, ophthalmic diseases such as conjunctivitis, keratitis, herpes zoster ophthalmicus, optic neuritis, haematological diseases such as acquired haemolytic anemia, idiopathic thrombocytopenic

Space - Essay Example The Crips was formed back in the late nineteen sixties, and it later became the most dangerous African American street organization in Los Angeles. The group was formed with the aim of representing black power, black pride, and was to address various injustices perpetrated on black people during that time. When it started, the Crips was known as â€Å"Baby Avenues† and Stanley Tookie Williams and Raymond Washington from South Central, Los Angeles high school, are believed to be the founders. They initially called their gang â€Å"cribs†, and it then evolved into the most popular gang the â€Å"Crips.† According to its creators, the gang was created as a way of defending its members against various rival gangs that were involved in innumerable wrong doings in the southern Central neighborhoods. The Crips’ activities have their origin on high school campuses in every part of Los Angeles. The Eastside Crips originated from Freemont High School while the oppos ite side of the 110Harbor Freeway was home for Westside Crips (Covey 48). Another group was established in Compton. The Bloods is a gang that was established in Compton, Piru Street (Street Gangs 1). The founders of the bloods are Vincent Owens and Sylvester Scott. Initially, the gang was referred to as Campton Pirus, and as time went by, the gang grew rapidly. Its growth was triggered by the disputes the Compton Pirus had with Compton Crips. During these disputes, the Pirus was brutally beaten and outnumbered. The Crips also treated other gangs badly and, for this reason, countless gangs decided to team up against the Crips. This is how the Bloods came to be. Today, the Bloods are known for their unforgiving attitude and take no prisoners mindset (covey 48) Since the 20th century, these two gangs have made Los Angeles to be ranked among the cities with the highest cases of crimes. The crime rate and crack use in south central became very high to a point that the area

Courtroom Technology Essay Example | Topics and Well Written Essays - 750 words

Courtroom Technology - Essay Example The result was a massive media spectacle. Some judges disapprove of cameras in the courtroom, suggesting that judges may end up playing up to the camera. It is generally considered a negative thing to have a great deal of media attention surrounding a trial as it may prejudice those involved. Different jurisdictions have different rules relating to this issue. Indeed, even some Supreme Court Justices have been somewhat schizophrenic on this issue. A few years ago, Justice Antonin Scalia, who has always taken a hard line against technology in the courtroom, expanded the notion of where technology was acceptable during a public speech he gave: During an April 7 speech by Scalia at a high school in Hattiesburg, a deputy federal marshal, Melanie Rube, demanded that AP reporter Denise Grones and Hattiesburg American reporter Antoinette Konz erase recordings of the justice's remarks. The reporters had not been told before the speech that they could not use tape recorders. When Grones resis ted, the marshal took the digital recorder out of her hands. The reporter then showed Rube how to erase the recording (AP). This issue caused a great deal of controversy at the time, and eventually led to an apology. Nevertheless, it has been reported that Justice Scalia is fond of the Ipad and uses it regularly. Clearly, the position of courts have everywhere have been evolving over the years. A timeline would suggest they have moved from conservative restriction to a more permissive, liberal approach. Standards vary from one jurisdiction and one judge to another. Indeed, other supreme court judges have been equally happy about the result of technology in the courtroom. One of the court's recent appointees, Justice Kagan, has the following to say about the huge amount of legal pleadings that justices have to work their way through: â€Å"At times there are as many as 50 friend-of-the-court briefs for one case. That is on top of the motions submitted directly by the named parties. So there is a lot of reading . . . And you know that's a big part of the job and if a Kindle or an iPad can make it easier, that's terrific" (Beahm). We see that people intimately involved in the judicial system have embraced technology in some ways, while rejecting it in others. We need to find ways to effectively implement technology across the board so long as it is helpful. There are a number of other ways that technology can be useful to those involved in the legal profession. For example, electronic discovery has made life very difficult for many lawyers. The sheer quantity of electronic documents involved in some cases makes it impossible to physically go through every document or email by hand. Special software is required to deal with these large quantities. This software can search through keywords to find important phrases or names. It can dramatically shorten the amount of time required to find what a lawyer is looking for. Both courts and lawyers can work together as pa rtners to develop and implement technologies in the courtroom. One system currently being used is called Digital Evidence Presentation System and allows for electronic, integrated presentation in the courtroom. As one expert says: â€Å"Although attorneys have significant control over the systems in the courtroom, the court has instantaneous override capability. With the touch of a button, a judge can turn off every screen in the courtroom, including the screens in the jury box and the large screen displaying

H.I.V in the Homeless in San Francisco, CA Essay

H.I.V in the Homeless in San Francisco, CA - Essay Example San Francisco is located within California, USA and is one of the leading regions in HIV prevention amongst other services such as, care, and treatment from the initial stages of the epidemic within the United States. The region is recognized for provision of high quality HIV care that also involves administration of antiretroviral therapy (ART). Such healthcare services within San Francisco benefits all residents regardless of their financial abilities. San Francisco Department of Public Health (SFDPH) has considered health of the community as priority since such initiatives are crucial in reducing morbidity and mortality in those living with HIV-infections. However, methods of initiating and administering ART have changed over time. Originally, ART was recommendable only for those who were immune compromised (either a CD4 cell count under 200 cells) (Kushel et al., 2006). However, there has been increase towards CD4 count on which ART was recommendable. This was due to availability of information on the adverse effects of HIV even in the presence of moderate immunodeficiency. This was also because of record decline in ART-related toxicity and pill burden. In the year 2011, there was pronounced evidence of the effect of ART on reduced risk of sexual transmission of HIV. The publication of such information triggered debate over the risks involved in delaying therapy. However, in 2012, the U.S. Department of Health and Human Services (DHHS) reviewed its policy and advised citizens on recommendations that ART.

Non hodgkins lymphoma Essay Example | Topics and Well Written Essays - 1250 words

Non hodgkins lymphoma - Essay Example These cancerous cells multiply and completely destroy the lymph nodes, tissues and vessels and later spreading (metastasizing) to other organs of the body. Lymphatic system of our bodies consists of many different parts. These are the lymph vessels, the lymph fluid and the lymph nodes. The entire lymphatic system consists of a large network of the lymph vessels that spread to all parts of the body tissues by branching and forming a network. These vessels carry the clear lymph fluid, chyle, white blood cells (mainly the smaller lymphocytes comprising of the T cells and the B cells) and also other blood cells to various parts of the body. Lymph nodes are the small pea shaped globular bodies found mainly along the way of the large blood vessels in the neck region, the chest, underarms, the abdomen and pelvis region and also in the groins. Lymph vessels are connected to these nodes and they act as filter removing harmful substances (if any) like the bacteria, from the lymph fluid. The lymphatic fluids along the lymphocytes re enter the circulatory system via the upper left part of the chest. The lymphatic system also consists of the spleen , the tonsils and the thymus gland. As the lymphatic tissue is present in many parts of the body including the bone marrow, the stomach and the small intestine, the non Hodgkins lymphoma can occur almost anywhere anytime. Though, it has been noticed that, the first to get affected are generally the lymph nodes which get enlarged when affected by the lymphoma. There are many types of non Hodgkins lymphoma (NHL) that are generally seen but all can be grouped under two main types. These are the slow growing or the indolent type and the second is the fast growing or the aggressive lymphoma variety. There is also a third variety which is the intermediate type. The NHL most often than not, form from the T cells or the B cells of the lymphocytes. The lymphocytes which form a part of the white
