“What Is the Evidence of Positive Benefits with Using T.E.N.S. (Transcutaneous Electrical Nerve Stimulation) Unit for Pain Management?”

...that if TENS were shown to be effective method of alleviating pain in Spinal Cord Injury (SPI) patients, it would decrease medical costs and improve quality of life. Bi discusses how their results are consistent with those of previous studies (Celik EC, The effect of low frequency TENS in the treatment of neuropathic pain in patients with spinal cord injury) which reported the effectiveness of TENS in the pain relief of SCI patients. The study had several limitation which were mention in the paper stating that the sample size of subjects was insufficient for generalization of the results, a follow up was not performed, and lastly they did not compare the efficacy of low frequency TENS with high frequency TENS because of the limited number of subjects. The study was fairly easy to read regarding vocabulary as well as length, the average patient would be able to understand what thte authors were speaking of but might be confused with the results since of the limitations they revealed and results they reported. At the end of this study the authors suggested that 12 weeks of TENS...

Water Quality and Contamination

...Week 5 – Water Quality and Contamination Final Lab Rona Harris SCI 207: Dependence of Man on the Environment Instructor: Jacqueline Poole 10/6/2013 Week 5 – Water Quality and Contamination Final Lab Abstract Testing of how ground water is affected by different contaminants was the bases of the experiment. The results were interesting in that when vinegar is filtered through dirt it came out fairly clean. This is surprising because I did not think that any of the contaminants used would affect the water the way it did with vinegar. I figured all the water would have dirt mixed in with the water that was filtered. This shows that maybe we can find a way to find a safer choice on how we filter and purify water. Introduction In this Lab we will explore how contaminants affect the water supply. Contaminants can be anything from human waste, chemicals used in farming and industrial factories to the laundry detergent and cooking oil that you use at home. We are going to asking how and why this affects us when we drink water from the faucet. One contaminant that is found in water is lead. Studies have shown that lead can led to developmental delays in kids and can cause cancer in adults. According to Bruce Lanphear a pediatric epidemiologist, “Lead in water is an underappreciated service of lead intake" (Renner, 2009. A544) It is estimated that 10-20% of children are exposed to lead through the drinking water according to the Centers for Disease Control and...

Hydropower and Nucleur Power

...Hydropower and Nuclear power Theresea Duplesis SCI 207 Dependence of Man on the Environment Gayle Leith February 13, 2012 At a time when our country needs to focus on not only domestic energy production, and ways to improve it, it also needs to find ways to create jobs. We have found that hydropower can play a critical role in doing both, by providing us with clean renewable energy while also helping to expand the job opportunities in rural America. (Tipton, 2012) Hydropower has already been found too serve a number of purposes, one it can produce renewable and emission-free energy. This in turn can be used to pump water or sell electricity to the grid. It also tends to help hydropower developers to pay for aging infrastructures and the modernization of water/power facilities. It also helps with creating local jobs and generating revenue for the Federal government. (Tipton, 2012) Legislation has been trying to find ways to streamline the regulatory process and to reduce administration costs. (Tipton, 2012) Developers have found that hydropower is one of the cheapest and cleanest sources of electricity. Even though, “Hydropower has been found to be the highest source of non-carbon emitting energy in the world.” It still only accounts for 75% of the United States total renewable electricity generation. (Tipton, 2012) Nevertheless, because of many unnecessary regulations that stand in their way only a few of the western...

Ankola, V. Bhardwaj, D.K. Sahana, M.N.V. Ravi Kumar ⁎ Department of Pharmaceutics, National Institute of Pharmaceutical Education and Research (NIPER), Phase-X, S.A.S. Nagar, Mohali, Punjab, India - 160062 Received 31 January 2006; accepted 26 April 2006 Available online 13 May 2006 Abstract Antioxidants are emerging as prophylactic and therapeutic agents. These are the agents, which scavenge free radicals otherwise reactive oxygen species and prevent the damage caused by them. Free radicals have been associated with pathogenesis of various disorders like cancer, diabetes, cardiovascular diseases, autoimmune diseases, neurodegenerative disorders and are implicated in aging. Several antioxidants like SOD, CAT, epigallocatechin-3-O-gallate, lycopene, ellagic acid, coenzyme Q10, indole-3-carbinol, genistein, quercetin, vitamin C and vitamin E have been found to be pharmacologically active as prophylactic and therapeutic agents for above mentioned diseases. Antioxidants are part of diet but their bioavailability through dietary supplementation depends on several factors. This major drawback of dietary agents may be due to one or many of the several factors like poor solubility, inefficient permeability, instability due to storage of food, first pass effect and GI degradation.

Received: 28 June 2012; in revised form: 24 August 2012 / Accepted: 28 August 2012 / Published: 5 September 2012 Abstract: In the past decade, research has accumulated suggesting that excessive Internet use can lead to the development of a behavioral addiction. Internet addiction has been considered as a serious threat to mental health and the excessive use of the Internet has been linked to a variety of negative psychosocial consequences. The aim of this review is to identify all empirical studies to date that used neuroimaging techniques to shed light upon the emerging mental health problem of Internet and gaming addiction from a neuroscientific perspective. Neuroimaging studies offer an advantage over traditional survey and behavioral research because with this method, it is possible to distinguish particular brain areas that are involved in the development and maintenance of addiction. A systematic literature search was conducted, identifying 18 studies. These studies...

Television, DVDs, video games, the Internet, and smart phones all play a formative role in children’s development. The term ‘‘technology’’ subsumes a large variety of somewhat independent items, and it is no surprise that current research indicates causes for both optimism and concern depending upon the content of the technology, the context in which the technology immerses the user, and the user’s developmental stage. Furthermore, because the field is still in its infancy, results can be surprising: video games designed to be reasonably mindless result in widespread enhancements of various abilities, acting, we will argue, as exemplary learning tools. Counterintuitive outcomes like these, besides being practically relevant, challenge and eventually lead to refinement of theories concerning fundamental principles of brain plasticity and learning.

H Critchley Regional Poisoning Treatment Centre, and University Department of Therapeutics and Clinical Pharmacology, The Royal Infirmary, Edinburgh, EH3 9YW, Scotland INTRODUCTION Acetaminophen (paracetamol, N-acetyl-p-aminophenol, 4-hydroxyacetani­ lide) is a non-prescription antipyretic analgesic that was first introduced into clinical medicine towards the end of the last century (1). It attracted little interest until it was found to be the major metabolite of both acetani­ lide and phenacetin (2, 3) and in recent years it has become an increasingly popular substitute for aspirin. Acetaminophen seemed to be remarkably safe when taken in recommended doses and formal toxicity studies were never carried out. In 1964 Eder (4) first reported liver damage in cats given 25-50 mglKg of acetaminophen daily for 26 weeks, and two years later Boyd & Bereczky described extensive hepatic necrosis in acute toxicity studies in rats (5). At the same time liver damage was first reported in man following acetaminophen overdosage (6, 7). The use of acetaminophen for self-poisoning has since increased dramatically in many countries and acute hepatic necrosis, sometimes fatal, has attracted much attention as the major complication (8-16). CLINICAL MANIFESTATIONS AND COMPLICATIONS OF ACETAMINOPHEN POISONING Apart from nausea and vomiting there are no specific early signs of severe intoxication and consciousness...
