Alternative Therapy: Fake Medicine?

- Many doctors see alternative therapies as only a joke in the medical field. New ideas and procedures without surgery or the use of medication are being portrayed as fake, unneeded and ineffective. Many are not considered serious medicine by the medical field specialists. There has to be another way to help heal the body instead of cutting patients open, or shoving all types of medications into patient’s bodies. Although alternative therapies are not taken seriously by doctors, the therapies are becoming increasingly more popular each day....   [tags: Medical Research]

Intraoperative and Postoperative Complications of Hypothermia

- Reviewing the Literature Hypothermia is a common problem in surgical patients. Up to 70% of patients experience some degree of hypothermia that is undergoing anesthetic surgery. Complications include but are not limited to wound infections, myocardial ischemia, and greater oxygen demands. The formal definition of hypothermia is when the patient’s core body temperature drops below 36 degrees Celsius or 98.6 degrees Fahrenheit. Thus, the purpose of the paper is to synthesize what studies reveal about the current state of knowledge on the effects of pre-operative warming of patient’s postoperative temperatures....   [tags: Medical Research]

Advantages of Adult Stem Cell Therapy

- The advancement of biomedical research has improved stem cell therapies immensely. There is a lot of unnecessary debate about the advantages and disadvantages of adult stem cell therapy versus embryonic stem cell therapy, which could be avoided if people were more knowledgeable of both therapies. Adult stem cell therapy is far superior to embryonic stem cell therapy because it avoids ethical concerns, the patients can use their own cells, and adult stem cells can be transformed into a pluripotent stage....   [tags: Medical Research]

Individual Differences in Visual Perception

- Group studies rest on the assumption that cognitive processes are homogenous, any variability is not considered important but rather a nuisance and so data is averaged across the subjects in order to reduce this “noise” or the influence of measurement error.

DNA Hydroxymethylation of Mammals

- Epigenetic changes refer to mechanisms which alter gene expression without altering the underlying DNA sequence. Sometimes, these changes are inherited throughout the cell’s life via cell division. Mechanisms that induce epigenetic changes include DNA methylation, histone modification, prions (which can be inherited without modifying the genome), and RNA signalling. This paper will focus on DNA hydroxymethylation in mammals. DNA methylation is a postreplicative modification that occurs when a methyl (-CH3) group is added at position 5 of the cytosine pyrimidine ring and “establishes a silent chromatin state by collaborating with proteins that modify nucleosomes.” (Rudolf Jaenisch, 2003)....   [tags: Medical Research]
