Mitochondria Essay -- essays research papers

Mitochondria Mitochondria are tiny organelles found in nearly all eukaryotic cells. They are rather large organelles ranging from 0.5Â µm to 10Â µm in length and 1Â µm in diameter. The mitochondria are the energy factories of the cell and are located in the cytoplasm. They are the sites of cellular respiration. The mitochondria are responsible for generating ATP from such organic fuels as simple sugars and fats in the process of cellular respiration. This doubled-membrane organelle has its own DNA and can reproduce by splitting itself. The mitochondria are sausage-shaped structures that move, change their shape and divide. They are distinct organelles with two membranes, the inner membrane and the outer membrane. The outer membrane is smooth and limits the organelle. It is highly permeable to small solutes such as molecules and ions, but it blocks off passages of proteins and other macromolecules. The inner membrane of the mitochondria is folded into shelf like structures called cristae. The cristae does not even allow the passage of small ions and so it maintains a closed space within the cell. The many infoldings of the cristae are responsible for providing the mitochondrion with a large surface area which enhances the productivity of respiration. The inner membrane and outer membrane effectively divide the mitochondria into two internal compartments. The space located between the outer and inner mitochondrial membrane is called the intermembrane space. The space enclosed by th...

The management of medical emergencies Essay

The management of medical emergencies at initial stages has many impacts in the development of the medical situation. By being proficient enough in managing medical emergencies in primary care setting, one has comprehensive and first-hand information. This information is very helpful to help the medical practitioners implement the most relevant measures to the situation. In the case of sexual assault, proper medication will be prescribed to the victim of the assault immediately before the situation grows very critical and complex to handle. Taking for instance, sexual assault where the victim risked contracting sexually transmitted infection. In this scenario, the most appropriate post exposure measures will be prescribe to the person to prevent the enhancement of the disease. Proper management of emergencies is the main determiner of the future progress in the situation. In emergency cases at primary care setting, it is possible that professional trainees will not have the opportunity to contemporaneously experience an emergency in which they learn and practice skills during the General Practitioners part of their training; therefore not fulfilling a major part of the every medical college curriculum. Some may feel that the Specialist Trainees will get sufficient experience in managing acute emergencies during the secondary care part of their training, but there are several reasons why is felt that specific training for primary care setting is essential. With the expansion of training in General Practitioners from 12 to 18 months at the expense of secondary training, specialist trainees will be exposed to fewer opportunities to experience acute emergencies due to the lower prevalence in primary as opposed to secondary care. Moreover, with the move to create, secondary care posts located predominantly in outpatient departments or future polyclinic facilities, the opportunity for emergency care experience will decrease even more over the full scope of General Practitioner training (Amorosi & Thorn, 2012, p. 77). In contrast, in primary care, though the materials are usually available and maintained in case an emergency situation should arise, these skills are rarely used. Moreover, the supportive practitioners (nurses, receptionist and fellow clinicians), though receiving yearly training; may wait years before they get to practise their skills on a real case. Furthermore, the specialist trainee, being transplant from the relatively standardized and familiar context of the hospital or outpatient department to a new and much more variable care setting, will be disoriented and relatively isolated if he or she is confront with a patient having a life-threatening event. Finally, many Specialist trainees while having participated in the provision of emergency care will never have taken the responsibility for directing the care, to lead the clinician during the emergency (Goldfrank, 2010, p. 86). Evidence based plan of care is very beneficial in an emergency. The evidence in the emergency provides medical practitioners with information about the cause of the emergency. This data not only ensures proper medication to the affected, but also gives nurses and clinicians confidence in approaching the emergency. Confidence in the clinician motivates in their effort to assist the affected person. The victims of the emergency stand a better chance to acquire quality and proper medication. Proper medications that come with the evidence to the emergency facilitate the chances of survival to emergency victim. In most situations, emergency victims are very critical and, therefore, they deserve a high attention to safe (Queenan, 2012, p. 112). By provision of evidence about the cause of their ailment, their chances of survival are increase by proper administration of medication. Evidence based plan of care is cost effective in an emergency. A lot is a waste through trying to minimise a situation that lacks evidence of its rise. Through provision of the causes that result to an emergency, many resources that could be used in search for evidence are saved. In evidence base plan of care, there is both subjective and objective information that is available. Subjective information comprises of all material facts about causes of the ailment. These may information of the real causes of the ailment that led to ailment.in the case of an accident, the subjective information is that the emergency result from sudden impact of the accident. Objective information, on the other hand, entails all those details about an emergence that would guide medical practitioners in treating the victim of an emergency. Such information includes information such as the time when the emergency occurred and how the victim was affect by the situation. It helps the medical practitioners to judge the victim biologically and try to help him as from the information acquired. For instance, in a situation where the victim was involve in a road accident the interest about the evidence that a medical practitioner may wish to know, are details like how long it has taken the victim since the occurrence of the accident. The levels of blood loss, if any and the intensity of the result of an accident to the victim’s body are amongst the important facts for a medical practitioner. These goal Facts would guide the medical practitioner in describing the most appropriate medication to the victim. Proper medication would mean high chances of recovery to the victim. Evidence based plan of care is the most reliable for effective medication. References Amorosi,  E., & Thorn,  G. (2012). Managing Medical Emergencies. New York: The Author. Goldfrank,  L. (2010).

Globalization And Its Effects On Society - 1011 Words

For thousands of years people and businesses around the world have interacted and integrated with each other. This is called globalization. Globalization has reformed almost every industry and affects billions of lives whether you realize it or not.
