Alternative Medicine - Research Paper Example ity of ‘old wives tales’ or ‘ancient lore’, both of which are frequently credited with time-tested knowledge that has worked for generations but also viewed with some suspicion. In some cases, the information is quite valid and the necessary research to support it is becoming increasingly available. In other cases, though, the information has been proven wrong, ineffective and sometimes even counterintuitive. Because it is impossible to know, with just an initial look, whether the claims of the article or legend are true as stated, it’s a good idea to question the claims made by conducting a thorough analysis. One substance frequently being used as an alternative to drug therapy for the treatment of inflammatory bowel disease and several other common ailments is the herb known commonly as yarrow. There are a number of different cultivars of yarrow which thrive in many parts of the world, many of which have long-standing traditions as a medicinal treatment. The scientific name for the plant is Achillea millefolium, but because of its widespread presence, it also has many common names. These include gordaldo, nosebleed plant, old man’s pepper, sanguinary, milfoil, soldier’s woundwort, thousand-leaf and feather-leaf (Dodson & Dunmire, 2007). Some of these names provide a suggestion of how it is used. The plant is said to have been named because of its association with the Greek hero Achilles. â€Å"According to the legend, Achilles’ mother held him by the heels and dipped him in a bath of yarrow. Achilles was forever protected by the herb except for the heels† (Madocks, 2009). Stories of Achilles indicate he always carried yarrow with him into battle because it had the ability to staunch the flow of blood from battle-inflicted wounds. â€Å"In the a ncient world, yarrow was seen as a potent healing agent, whether applied to a wound or taken internally to prevent a cold setting in. Yarrow was the preferred domestic medicine of yesteryears’ mothers who

Can poverty be stoped in Africa Essay Example | Topics and Well Written Essays - 1000 words

Can poverty be stoped in Africa - Essay Example But such basic causes are quite intractable and not easily eradicated. In most cases, the causes and effects of poverty interact, so that what makes people poor also creates conditions that keep them poor. Primary factors that may lead to poverty include (1) overpopulation, (2) the unequal distribution of resources in the world economy, (3) inability to meet high standards of living and costs of living, (4) inadequate education and employment opportunities, (5) environmental degradation, (6) certain economic and demographic trends, and (7) welfare incentives" ( Microsoft Encarta 2006 ). Just like many third world countries, Africa is not exempted from incurring debts. Many western governments have made promises to either reduce or remove the massive burden of debt in Africa. Yet, in most African countries, the people still devote most of their land planting and producing cash crops to pay off these debts. However, the debt is so enormous that the possibility to pay the debt off is next to impossible. This creates a vicious cycle in Africa's economy, with the government and its people burrowed deeper into this situation. The phenomenon of jobless economic growth that increases income inequalities and generates too few jobs for low income groups poses a serious threat to the well-being of many nations, both North and South. Government policies should consider not only aggregate economic impact but also the distribution of employment. Socially responsible venture capital and microcredit initiatives can foster employment-generating businesses that complement the local culture and environment. .b. Rout out corruption, which harms society as a whole. Corruption, both in government and business, places heavy cost on society. Businesses should enact, publicize and follow codes of conduct banning corruption on the part of their staff and directors. Citizens must demand greater transparency on the part of both government and the corporate sector and create reform movements where needed. b. Broaden access to education and technology among marginalized groups, and especially among girls and women. The educational attainment of women has strong bearing on the well-being of their families, and efforts to improve education for women and girls must be strengthened. At the same time, steps should be taken to ensure that the current revolution in information technology benefits marginalized groups. This must begin in school. c. Improve government capacity to provide universal access to essential goods and services, including potable water, affordable food, primary health care, education, housing and other social services. Governments around the world have made commitments to this through the 20/20 Initiative, which calls for 20% of national budgets and 20% of foreign aid to be spent on human services. But raising adequate

Herein focusing on the region of China the government of the region is found to bring about changes in the policy structure related to manufacturing, research and development functions and also related to labor relations to contribute in the overall developme nt of the social and economic situation of the region.

Locate the state of Marylands Constitution and examine the major Essay

Locate the state of Marylands Constitution and examine the major elements and articles of the constitution - Essay Example As part of a democratic country, the government’s power rest on the people. (MSA, 2011) This means that the people have the right to vote for their leaders and the right to voice out their concerns. They also have rights such as freedom of speech and freedom of religion. The highest official in the state is the governor. Once elected, the governor is expected to act according to what the people want him to do. All services are also implemented through the approval of the governor and the legislative department. (MSA, 20110) The government of Maryland offers various services for the people, such as free public school education, health services and judicial services. These services are funded by the government through the taxes paid by the citizens. The judicial power of the state is vested on the Court of Appeals, which is composed of seven judges. Under the Court of Appeals, there are different circuit courts and district courts. (MSA, 2011) The citizens can avail the services of the judiciary department by filing complaints on any legal manner to the appropriate court. (Maryland Judiciary, 2006) All manners of complaints are accepted by the judiciary, such as for crimes, civil claims, child support, divorce and others. The citizen who needs assistance form any court should fill up a form and submit it to the appropriate court. For example, if a citizen is filing for divorce, he or she must fill up a domestic relations form and submit it to the family services department of the district court in his or her place of residence. After this process, the citizen would have to wait for the documents that he or she has to provide in order for the divorce to push through.(Maryland Judiciary, 2006) The length of time for any legal process depends on the complaints. There is a chance that crimes may require more time than divorces. In cases when the district courts cannot handle a given complaint, or if it requires further legal intervention, then the complaint wo uld have to be passed on to the Court of Appeals. (Maryland Judiciary, 2011) The government also provides social services for families like children’s health care program, emergency assistance for families with children, child care program, and even burial assistance for those families who lost their children. The government also provides temporary cash assistance and refugee cash assistance for those in need. The government also provides public assistance for the elderly and the disabled. To some extent, the government can also help in providing jobs for those who are unemployed. (Maryland.gov, n.d.) One important service that the government provides to its citizens is the Temporary Cash Assistance (TCA). Implemented by the Department of Human Resources, this program provides cash assistance to needy families with dependent children, and who cannot provide for the family’s needs. (Department of Human Resources, Maryland.gov. n.d.) Those families whose incomes do not e xceed $ 2,000 are entitled to receive cash assistance from the government. In terms of education, the government provides several programs to help students. Aside from the free public school system, the government of Maryland also provides scholarship grants to students who fall under certain categories. The government also has a college savings plan, wherein the students choose a specific college plan that suits the family’

Research on behaviour of children with stay at home Essay Example for Free

Research on behaviour of children with stay at home Essay It is a personal and specific decision that has its perks as well as its pitfalls. Advancements in womens rights in the workplace have encouraged women to acquire higher paying Jobs. However, recent research suggests that more women are choosing to stay at home. It is not because of a lack of education or opportunity; they simply dont want to have someone else raise their children. A study by the National Institute of Child Health and Human Development (NICHD) in 1999 found that the more hours a child spent at a non- maternal care before age 5, the less positive the childs interactions with his/her other will be. Two studies published in 2003 conducted by the NICHD found that children in day care had higher levels of stress and were more aggressive than those cared for at home by the mother. There are millions of children, however, who have working mothers and who grow up to be responsible, sucessful adults. Benefits for children raised by stay-at-home mothers. STABILITY: This is the main benefir for your children. Knowing that you are there gives your child stability. You are able to answer your child questions, dry tears, and offer support. In addition, you will never get those year back. They experience fewer emotional and behavioural problems in childhood: want to help ensure your children turn out to be happy and socially well adjusted? Bond with them when they are infants. Thats the message from the university of Lowa, USA, which found that infants who have a close intimate relationship with their mothers are less likely to be troubled, aggressive or experience other emotional and behavioural problems when they reach school age. Bonding with your child has proven to help in a childs mental and emotional development. Consistency: Your children can rely on you. They can trust the consistency on the way you run your household. Being consistent with mealitimes, Chores, baths, and bedtimes teaches children organization and discipline. They need this consistency to give them structure and routine in their lives. Quality time: All kids need quality time with their mothers. Quality time gives them the assurance of being loved all the time. Quality time also keeps your child out of trouble, which often stems from boredom. the memories they will have of you depend on this quality time

Policing Practices and Operations Essay Example for Free

Policing Practices and Operations Essay Law enforcement officers have many duties. Law enforcement officers are sworn to serve and protect society as well as to fight crime. They also maintain order within their jurisdiction, as well as providing other services that the community will benefit from. Most of the time, police officers are considered to be crime fighters, in which this image has been brought to citizen’s attention by the media. The styles of policing should match the community in which they serve, so there is no conflict between the community and the law enforcement officer. The future policing structure does have a huge impact socially, economically, and politically within the community and the police departments general needs so that they can provide the proper policing that is needed. Life threatening situations take place in different circumstances, which includes the law enforcement agencies. Dangers Law enforcement officers face being wounded or murdered as they are on the line of duty in the United States, every year. The greatest threat a police officer will ever face is bodily harm and death. When a law enforcement officer is called to a scene and responds to a disturbance call, the law enforcement officer is confronted with the possibilities of violent actions from an armed suspect. Although, bodily harm as well as death upon a law enforcement officer are not the only dangers in policing. Family issues and stress related illnesses also can be contributing factors to the danger of a law enforcement officer and policing. Law enforcement officer’s jobs can surely take a toll on their lives as well as their well-being. If the pressures of their type of work are handled and coped with property, it could end up becoming life threatening. Today’s law enforcement officers are faced with many dangers within their everyday duties, like rival threats of getting shot. Examples are: vehicle pursuits, traffic control, and foot pursuit, stress, making an arrest, and sun exposure/duty equipment and biohazard exposure. These dangers are exposed to law enforcement officers on a daily basis. This is why it is important for law enforcement officers to wear their bulletproof vests as well as their belts that contain pepper spray, radio, handgun, baton, and handcuffs. All of this specified equipment usually will weigh up to about twenty pounds, which adds stress to the law enforcement officers hips, feet, knees, and back areas. Stress to the law enforcement officers body by getting in and out of their patrol vehicle up to about fifty times within one day, as they have to wear all of their equipment. Law enforcement officers are exposed to the extreme temperatures for many hours at a time. They may have to be in extreme heat c onditions, such as one hundred degree heat, while conducting traffic control at a scene of an accident. They also sometimes have to provide crime scene security when the weather may be in freezing conditions. Law enforcement officers are at the mercy of all weather conditions. Also, a lot of the times law enforcement officers are called to a scene and they are not properly prepared for it because of the weather conditions and they do not have the time to stop somewhere to get what they need to prepare themselves. They may have to stand out in extremely hot or freezing weather without the proper protection they may need or hydration they so desperately have to have. Law enforcement officer’s physical dangers have to be dealt with as well as trying to always be ready for the worst. As this can add so much mental and physical stress upon the law enforcement officer. They have to be aware of their surroundings and environment all the time. Law enforcement officers have to be alert as well as being prepared for all situations that may occur. The officer will rarely have time to get prepared for an emergency call. They have to sometimes rely on the training the received to be able to make important, split second decisions that are based on different circumstances. The September 11, 2001 terrorist attacks gained the attention from all the departments within law enforcement. Within the federal policing agencies, they took precautionary measures to make sure that the people of  the United States were safe. Even though, the local and state agencies have managed to keep the people’s fears under control within the United States and communities as well. All of the agencies in the United States have to work fearlessly on preventing and reducing the citizen’s fears caused by terrorism. When terrorism is looked into, law enforcement agencies and Homeland security across the world are very imperative that the agencies try to work together in solving the crimes by using shared information and by having departmental as sistance. All in all, terrorism is always a danger for law enforcement officers. Statistics As reports were published by the National Police Officer Memorial Funds said that in 2010, officer’s fatalities treacherously rose. There was a two year drop of law enforcement mortalities in 2010 that rose to 160. This was intensified by about forty percent compared by looking at the year before. The data gathered by the National Law Enforcement Officers Memorial Fund indicated that for the thirteenth consecutive year, the number one cause of law enforcement officers deaths were contributed by traffic fatalities, within thirty nine states. Puerto Rico and the District of Columbia were also involved in law enforcement officer’s related deaths in 2010. Within the third consecutive year in a row, Texas, Florida, and California were ranked on top of the five states that involved the most of law enforcement fatalities. The Federal law enforcement Officers had a total of eleven law enforcement officers that were lost, including the Federal agents that lost their lives in the line of duty during 2010, along with United States Customs, two United States Border Patrol agents, and three Border Protection officers. According with the Federal Bureau of Investigations (2011) website, it stated that fifty-six law enforcement officers were killed in the line of duty. Thirty two law enforcement officers that were among the fifty-six, were employed within city police departments. Thirteen of them were employed for law enforcement agencies within cities of a population consisting of 250,000 or more people that reside there. In Puerto Rico and twenty two other states, there was also line of duty deaths as well. There were fifteen law enforcement officers who lost their lives in ambush situations as well. There were fourteen law enforcement officers that lost their lives in felonious attacks while involved in arrest situations. There were eight law enforcement officers that were killed when they were investigating suspicious persons/circumstances. There were seven law enforcement officers that were killed while working on traffic stops/pursuits. Six law enforcement officers were killed while answering to disturbance calls. There were three law enforcement officers that were killed while they were involved in tactical situations, like high risk entry, barricaded offender, hostage situations, etc. There were two law enforcement officers that were killed upon conducting investigations while searching, interviewing, and looking at surveillance. And one law enforcement officer was killed as they were maintaining custody of a prisoner or while transporting a prisoner. With future policing, I feel that it is important to have close communication with the homeland security. I personally feel that the more communication there is, the more we will progress and bring better policing skills. It is equally as important to have communication with all law enforcement agencies to help in improving all policing operations that are dealt with. In future policing, the importance of keeping law enforcement agencies relationships maintained will build better and stronger agencies. With the relationship within law enforcement agencies and homeland security are not as accurate as seemed. It is understood that all agencies serve different purposes, as they are all in charge of different types of areas within society to serve and protect. I believe that joining forces with other agencies would be beneficial. It would be beneficial because by all working together, there could be issues that could be addressed a lot better. Along with lack of communication among law enforcement agencies and homeland security, we would be able to better handle the various criminal issues better. I feel that this can also improve community policing and law enforcement relationships. With the new technology equipment that police officers receive, they can work on their policing styles, such as being reactive or proactive. Once these issues are changed, there will be better communication with other law enforcement agencies, as they would be able to serve and protect in much more positive ways. This will decrease crime rates as well as increasing practices that  are reactive. As crime rates decrease, and proactive and reactive practices are being practiced, then the start of confidence will show within all law enforcement agencies. Although, there are many differences in the power as well as the authority, responsibilities and roles, and the difference in jurisdiction at the local, state, and federal levels within law enforcement officers. It is clearly apparent that all of the dangers within them remain equally the same. References American bar association. (2011). Standards on urban police functions.

Developments of Stem Cell Technology

Developments of Stem Cell Technology The research of embryonic stem cell is classified under the study of biotechnology, which is one of the most recognized areas of research by the public, as well as one that have the potentials of benefited from the completion of the research7. The embryonic stem cells are the absolute base form of all cells that is within a human, they are frequently known for two of their main characteristics. One is the ability to self-renew though a long period of time while remain non-specialised, and the other main characteristic is the stem cells ability to differentiate and give rise to any specialised cell3. Because of these characteristics, it brings hope to cure diseases that were not possible before, by replacing the damaged cell with a new one that is being derive from a stem cell. Neurodegenerative diseases are a prime example where scientists believe that stem cells are the key to treating the disease. However, the research of embryonic stem cells has always being surrounded with contro versy, due to the pro-life movement around the world. This report will be mainly focused on the use of stem cell on treating neurodegenerative diseases, and a general overview of the progress in the research of stem cells. (202 Words) Review The majority of the research done on embryonic stem cells is directed mostly toward medical treatment such as bone narrow transplant, regrowing a new nerve cell to heal Neurodegenerative diseases and more. The researches of stem cell started in the mid eighteen hundreds, when scientists discovered that some cells have the ability to generate into others. But the application of stem cell only start to boom from 1960s, when the human understanding on natural biological systems had increased to the point that it allowed scientists and doctors to do bone marrow transfers between two humans which resulted in curing a patient with severe combined immunodeficiency in 1968. This is the reason that stem cell research attracted attention from the public, due to the possibilities of curing several different types of diseases or healing damages that were beyond humans natural healing ability. Stem cells are the fundamental cells of all the different types of cells that are in a human body. It has the ability to renew itself, under the correct environment and performs obligatory asymmetric replication (see diagram 1 at appendix 1). This, combined with their ability to transform into any specific cell type that can be found in a human body, makes it possible to create new cells to replace those that were damaged by disease or treatment processes. However, the current understanding of the behaviour of stem cells is not enough for scientists and doctors to use them to completely cure a certain disease. Nevertheless, we currently have enough understanding through research, to show that stem cells do have the ability to lessen the symptoms such ailments as Alzhei mers disease. The research into stem cells has potential of curing most of the long-term diseases known to doctors; however the cost of this research is the main reason of controversy. The reason of the controversy around stem cells is focused mainly because embryonic stem cells can only be gathered when an egg is being fertilized. The process of gathering a sample of stem cells started by triggering a human egg that has been left in cryo for more than the legal limit, to grow into an embryo like the normal growth of a child. Afterward, the egg started to grow for five to seven days where the blastocyst started to form along with the inner cell mass. The whole blastocyst is then moved to a specially prepared culturing plate that is covered in a feeder layer, that is designed to support the growth of the stem cell, and chemicals are added to break the blastocyst to allow the inner cell mass to be exposed. From this point on it is merely waiting for the inner cell mass to grow and divide into stem cells that the researcher can use to test in a controlled environment by using different growth factors that will hopefully allow the scientist to map out the reaction of different types of proteins and the chemical environment that would decide the growth path of these stem cells (see diagram at appendix 2). By this point, most biotechnologists require assistance from people in another field, such as chemical engineer, protein specialist and doctors to help culturing or to understand how this stem cell works. These specialist from other field of science, help scientists to understand the growth factor that is involved in the differentiation of the cells. A prime example would be the use of growth factors. Unfortunately this is also where the controversy starts; a lot of people around the world that support pro-life organisations believe that the research of stem cells is immoral; since every embryo that is being used to extract the stem cells have the possibility of becoming a full child, thus the process of extracting the stem cells would destroy the possibility of life. They believe that the same research can be conducted through adult stem cells, or known as somatic stem cells, that can be isolated from bone narrow, or any other cells that have the ability to self repair, without the need of creating a full embryo. While it may be possible to do so, the concentrations of somatic stem cells are extremely hard to isolate and researchers are currently unable to grow them in cultures for further study. However, most scientists believe that while each embryo has the possibility of developing into a child, the long period of cryo that is used to store the egg, is damaging it, to a point that the death rate of the infant will be higher, along with the fact that these cells were originally scheduled to be destroyed, thus it does not make much difference. Therefore, until either the somatic stem cells can be cultured and proven to be as potent as embryonic stem cells, or the latest induced pluripotent stem cells that are created by reprogramming the adult stem cell back into the pluripotent stem cell stage of development. Scientists are stuck on using embryonic stem cells for the majority of the study. (792) Application Case study The advancement in the field of biotechnologys research into stem cells has already started to show results. In the past, diseases such as Alzheimers, which are diseases that cause the degradation of neurons on nerve cells, which were not treatable by doctors before. The most that doctors were able to do was to relieve the pain caused by the disease, they were not able to locate the source of the disease, or how they affected patients. However, since the development of stem cell technology, scientists have regain hope of finding cure or treatment process that can permanent treat these diseases. Using the same system that was originally designed to house the stem cells, they were able to isolate the infected neuron samples that were affected by the diseases, and therefore, were able to devise a treatment or cure for the diseases as they now have a sample with which they can work. Alzheimers disease is one of the most common neuron degradation diseases seen in the world. In America alone, there are at least 5.3 million people that have this disease. Alzheimers disease attacks the nerves and neurons that are in the brain over a long period of time, which slowly causes memory loss, problem solving skills, thinking, to the point that the brain can no longer function properly, leading to death. Alzheimers disease currently has no cure, as the rate that the human body regenerates the brain cells are much slower than the rate of infection. Therefore, theoretically it will be possible to cure Alzheimers if all infected nerve cells could be removed, and replaced with new nerve cells that were derived from the adult stem cell of the patient. This same application can also be used on other diseases such as Parkinsons disease or sport injury that normally requires years of recovery. Based on a published journal in 2009, scientists were able to use bone marrow derived the mesenchymal stem cell to relieve symptoms of Alzheimers on a mice model that have been purposely induced. According to the research journal, when a patient (or mice in their case) that is presented with the disease, the concentration of amyloid-b (Ab) peptides in the form of amyloid plaques in the brain parenchyma increases, which causes neural loss to the patient. Therefore, in a direct treatment the research team injected bone-marrow-derived-mesenchymal stem cells into the brain of the induced mice, the result showed that there is a diminution of amyloid-b by the reactivation of microglia that were re-stimulated by the injection of the stem cells. Thus the research team arrived at the conclusion that BMMSCs can promote reduction of the amyloid-b through the microglial activation in the induced Alzheimers brain, suggesting a potential therapeutic agent against Alzheimers disease. (453) however, in the journal the research team fail to considered the other cause of Alzheimer the neruofibrillary tangles Conclusion In conclusion, it is clear that the development of stem cells is one field of biotechnology that is emerging quickly as the understanding of natural biological systems increase, along with the fact that the diversity of biotechnology is potentially limitless in the field of medical research. For example, during the process of creating a suitable environment for the embryonic stem cells to grow, researchers have accidentally created a solution that can keep donated organs for longer periods of time, allowing a higher chance of success to the transplant surgery after a long period of travel. In the future, once more is understood about stem cells, the whole technology may be advanced enough to reconstruct an entire limb. There remains much controversy around this field, due to the researchers ethical practices, notably, obtaining new stem cells. Referencing Kil Lee, Jong, Hee Kyung Jin, and Jae-sung Bae.
