Brain Cancer Innovation: Attacking the Core :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  In the article Brain Cancer Innovation: Attacking the Core, Anne Denogeantries to clarify how deadly glioma (malignant tumor of the neurological cells) actually is, and how a balloon filled with radiation can extend a patients life.   Ã‚  Ã‚  Ã‚  Ã‚  Anne goes on to explain that this treatment is not a cure but on average it doesgive the patient additional months if he or she did not take the surgery. This procedure is done to treat some of the most severe cases of glioma, which was recorded to end up in an average of nine thousand four hundred Americans every year. She also says that this method of using a balloon has been the best when it comes to not damaging any of the patient’s brain tissue. Doctors have been searching for something like this for many years.   Ã‚  Ã‚  Ã‚  Ã‚   The patients that are diagnosed with this illness are usually between the ageof thirty to fifty years old. When these people come in for surgery to cut out the cancer, they usually come out of the room with no brain with the cancer completely gone. The problem with this style of surgery is the cancer comes back after only a short period of time. This is where the radiation balloon (which is used at the University of Arizona and many other sites in America) comes into play. This balloon was created in such a way that it is able to secrete about two centimeters of radiation fluid every time it detects the tumor is getting to large. This is a cheaper more sufficient treatment for glioma patients to choose rather than many surgeries.   Ã‚  Ã‚  Ã‚  Ã‚  The balloon is attached to the catheter during the removal of the tumor. Once it is in the correct position it is filled up with saline. So far, there has been one person that

Drug Abuse Essays -- Drugs Narcotics Research Papers

Drug Abuse   Ã‚  Ã‚  Ã‚  Ã‚  Drug Abuse is generally defined as the use of a drug with such frequency that the user has physical or mental harm or it impairs social abilities. The substances that are discussed in this report are called psychoactive drugs; those drugs that influence or alter the workings of the mind, affect moods, emotions, feelings, and thinking processes. Drug Dependence/Addiction   Ã‚  Ã‚  Ã‚  Ã‚  There are three basic characteristics that indicate that the user is dependent on a drug. First, the user continues to use the drug for an extended period of time. Second, the user finds it difficult to stop using the drug. They may drop out of school, steal, go to jail, lose their jobs, or leave their families in order to keep using. Finally, the user has withdrawal symptoms when drug use is stopped. They may undergo physical pain or mental distress. The drug mimics a natural process in the brain called neurotransmission. This is when a brain cell releases a signal to another brain cell. The signal then returns to the first brain cell. The signal is called a neurotransmitter. One major neurotransmitter is called dopamine, which is involved in feelings of pleasure. When the drug is released into the brain, it blocks the dopamine from returning to the first brain cell. Repeated use changes the brain cells so that normal messages can't be sent between brain cells. The drug must always be present in order for neurotransmissions to take place. The user is only able to feel pleasure from the cocaine rather than the things he/she used to find pleasurable. This is called drug addiction or dependence. Drug Classification Drugs are generally categorized into two groups, stimulants and depressants. Stimulants are drugs that speed up signals through the nervous system. They produce alertness, arousal and excitability. They also inhibit fatigue and sleep. They include the amphetamines, such as cocaine, caffeine, and nicotine. Depressants slow down the signals through the nervous system. They produce relaxation, lowering of anxiety, drowsiness, and sleep. They include sedatives (such as barbiturates, alcohol, and tranquilizers) and narcotics (heroin, morphine, opium, codeine), which dull the mind's perception of pain.   Ã‚  Ã‚  Ã‚  Ã‚  Some drugs are not included in the stimulant/depressant categories. An example is the hallucinogens, such as PCP and LS... ...nclude nausea, diarrhea, and pain, but they vary between drugs. Cocaine users report depression when denied the drug. Since heroin is a very addictive drug, it has many withdrawal symptoms. For example, insomnia, muscle cramps, nausea, sweating, chills, panic, tremors, loss of appetite, yawning, runny nose, and watery eyes. Drug Treatment   Ã‚  Ã‚  Ã‚  Ã‚  A drug addict generally goes through denial before he/she accepts his/her drug addiction. When they are confronted by a family member or friend, they refuse to accept that they are addicted. This is sometimes called a mental block. The user isn't ready or able to deal with thier addiction. The time period of denial varies from person to person.   Ã‚  Ã‚  Ã‚  Ã‚  When the person has come to accepting their problem, they may go to therapy for treatment. Group therapy has had excellent results. They learn to come to terms with their problem with the support of other people who are going through the same thing that they are. They also learn tools that they can use to help them through the recovery period, such as prayer, excercise, and meditation. Drug abuse is a serious problem, but through treatment and therapy, it can be overcome.

2/15/2013 background on transformation of bacteria with pGLO plasmid Experiment #5 Aim: Purpose of this lab is to have plasmid activity transformed Material: Bacteria starter plate, pGLO DNA Plasmid, microcentrifuge tubes, Ice, water bath, CaCl2 Transformation solution, (LB) agar plate, (LB/Amp) agar plate, (LB/Amp/ara) agar plate, Micropipette, and Micropipette tips. Method: Genetic transformation is a procedure which is done by taking genes from one organism and putting them in another organism.A gene is a piece of DNA that instruct for making a new protein and from this protein organism a certain trait. A gene is inserted into an organism in order to change the organism’s trait. This procedure lab is divided into two day lab. On day one, we started the procedure with getting agar plate where HB101 bacteria were growing for 24 hours at 37C. We began by first labeling two microtubes; one with (+pGLO) and second with (-pGLO). 250ul of transformation solution which we used (CaC l2) was transfer to each tubes and placed those tubes on ice.HB101 bacteria single colony was picked by using sterile inoculation loop and immersed into (+pGLO) tube and later immersed into (-pGLO) using same technique. Both time we used different sterile inoculation loop. The tubes were placed back into the ice after mixing well the colony each time. The pGLO plasmid DNA was added by the instructor into (+pGLO) not into (-PGLO) tube and placed the tube back into ice. The tubes were incubated on ice for 10 minutes. Once done incubating both tubes were performed heat shocks at 42 degree C temperature for 50 second.Both tubes were immediately placed into the ice for another 2 minutes. After 2 minutes, 250ul of LB broth was added to each tube and again incubated for 10 minutes at room temperature. Once the incubation was done, we transferred 100ul of cell suspension to the plates which was provided by using the table LB/Amp| LB/Amp/ara| LB/Amp| LB| (+pGLO)| (+pGLO)| (-pGLO)| (-pGLO)| O nce the cell suspension was transferred, cells were gently spread 10 swipes using inoculation loop on the agar and rotated the plate 45 degree. The plates were placed into incubator at 37 degrees by turning he tubes upside down and taping them. Result:

Quality Assurance Essay Example | Topics and Well Written Essays - 1250 words - 1

Quality Assurance - Essay Example Quality assurance is a vital aspect in any organisation that needs to offer unparalleled products or services. Quality assurance is the implementation of all systematic activities that are geared towards provision of quality products and services. All organisations that adhere to quality control are in a position to make a positive impact in the provision of products and services.This is an activity that is directed towards fulfilling the needs of the demand for the services and products. Quality control is mostly inclined towards satisfaction of those in need the services and products. In quality control, an organisation’s interests are not paramount. However, the interests of the consumer reign supreme. Quality Concepts An organisation that needs to apply quality control has to go through various procedures to attain the best. It is not an easy task to implement quality assurance and it will take time and other resources including finance and labour. First, the organisation has to carry out a concrete system analysis. Organisations have to come up with a system that will be operational in the organisation in order to meet the requirements. In this initial step, the organisation has to consult with concerned parties to come up with a functional system. This will involve consultation, meeting with other parties consulting research in making a strong system. This will be followed by development of the system to ensure it will function in the organisation. Analysing and developing a system that is not functional in the organisation will be a waste of time and resources. ... As such, there will be limited instances of conflict of interest. Secondly, there has to be procedures that will be followed in implementation of the system. Following procedures will ensure the system will be implemented in a standardised form. Some procedures will be vital and should be done before taking any other step in the system. Thirdly there will be a need for reference materials. The system should be backed up with materials that will be used in future in ensuring the system is followed appropriately. The last part of applying quality assurance is informing the concerned parties of the system in place. Passing information explicitly will be a benefit to the organisation as all the employees or people in the organisation will be prepared to execute the system. This will be followed by instructing the organisation on the possible measures that will be in place when implementing the system. Lastly, there will be a need to train the staff in ensuring the system is fully execute d. Since the workforce is directly involved, they will have to get ample training and preparation for the system that should be put in place. When considering the application of quality assurance in an organisation, there are several parameters that are considered. First, there is constant training of the concerned parties and employees. The employees are directly involved in ensuring quality standards are maintained. Therefore, constant training of the employees will ensure the quality of products or services are kept in high standards. In many instances, organisations that practice employee training are at the helm of making positive accrual in their line of service or products. Secondly, there is need for constant

Analysis and apply the various theories and schools of thought for Essay

Analysis and apply the various theories and schools of thought for California Lutheran University - Essay Example In its policy, CLU offers equal opportunities to all qualified individuals regardless of their color, race, gender, origin, or disability. The classical theories The classical theories were developed by different scholars, whose main assumptions were largely based on the relations between the management and employees (Helrich, 2012). This is attained through structures, which are formally made to enable smooth communication process, established accountability, and official practices and procedures to prevent any kind of disputes. In the California Lutheran University, the management includes the University administrators and the directors, while lecturers and other subordinate staff are the employees. They have formally made procedures to be followed such as timetables of lectures and other schedules to ensure that there is no conflict between them and the students. Workers are treated as economic individuals whose motivation is money. However, they are regarded as products of means of production. Henry Fayol came up with fourteen principles of an organization, such as division of work, authority and responsibility, discipline, and unity of command. In this university, all these principles have been applied on both the faculties and the students. The workers are dedicated to working with small numbers of graduate and undergraduate students who are disciplined, and open-minded about everybody, about ideas, and about their faith. Each student is seeking to grow as an individual while pursuing his or her passion and discover his purpose. The bureaucratic Theory of Management initiated by Max Weber helps an organization achieve objectives and goals. To him, an organization is efficient if has a continuous organization of formal functions interconnected by regulations, a hierarchy in administration, and rules to regulate office conducts. The institution has formal hierarchies from the University president down to the students. The governing bodies include the Convoc ation, Regents’ Board, the Cabinet of the President, and the Faculty. The executive cabinet provides leadership for the Programs Board and the senate to ensure that policies are executed and implemented. The Programs Board on the other hand officially represents the interests and wishes of all the students enrolled in the University. This hierarchy of roles runs down from the president of the institution to the students’ body to ensure that there is proper definition in tasks for a proper operations and order. The Human Resources management Human relations and schools of thought The Human Resource part of California Lutheran University has several departments, which work collectively to ensure that administrative roles and other responsibilities are achieved as desired. For instance, the senior Human Resource Administrator of the University administers all institutional compensation programs. He works with the HR Director on most of the scheduled projects such as analy sis, implementation, design, yearly salary programs, and budgeting. He assists the director with termination or disciplinary issues and general relations with the employees. The Director of Adult Degree Evening Program oversees faculty-student relations and recruitment and leads enrolment goal achievement, retention strategies, and excellence in student activities. The central aspect of the Human Relations school of thought is that when workers work
