Scientists have developed a gel that helps brains recover from traumatic injuries. It has the potential to treat head injuries suffered in combat, car accidents, falls, or gunshot wounds. Developed by Dr. Ning Zhang at Clemson University in South Carolina, the gel is injected in liquid form at the site of injury and stimulates the growth of stem cells there.

Brain injuries are particularly hard to repair, since injured tissues swell up and can cause additional damage to the cells. So far, treatments have tried to limit this secondary damage by lowering the temperature or relieving the pressure at the site of injury. However, these techniques are often not very effective.

More recently, scientists have considered transplanting donor brain cells into the wound to repair damaged tissue. This method has so far had limited results when treating brain injuries. The donor cells often fail to grow or stimulate repair at the injury site, possibly because of the inflammation and scarring present there. The injury site also typically has very limited blood supply and connective tissue, which might prevent donor cells from getting the nutrients they require.

Dr. Zhang's gel, however, can be loaded with different chemicals to stimulate various biological processes at the site of injury. In previous research done on rats, she was able to use the gel to help re-establish full blood supply at the site of brain injury. This could help create a better environment for donor cells.

In a follow-up study, Dr. Zhang loaded the gel with immature stem cells, as well as the chemicals they needed to develop into full-fledged adult brain cells. When rats with severe brain injuries were treated with this mixture for eight weeks, they showed signs of significant recovery.

The new gel could treat patients at varying stages following injury, and is expected to be ready for testing in humans in about three years.

Intro Problem Solving L04

...other times, however, you will face problems that are more complex. These require you to follow a systematic approach to define and analyze the problem, develop and analyze possible solutions, choose the best solution, and implement a plan of action. The amount of time and resources you apply to any given problem depends on its complexity, the amount of time available, and your experience as a leader. In this section, you will learn about the Army problem solving process— a systematic, logical approach to problem solving and decision making designed to help leaders make better decisions. As a junior officer, you may not face a decision on the scale of that facing BG John Buford on 30 June 1863. But using this systematic approach to problem solving can help you make decisions as solid as the one he made that day. Buford Decides to Stand and Fight Immediately south of Gettysburg the topography was considerably more striking [Figure 5.1]. As John Ropes put it, “Round Top Hill is quite an anomaly, and looks as if dropped down from New England.” This distinctive and soonto-be-famous topography actually contained what could be regarded as four anomalies for that region.

Violence

...violence can be a series of actions which an individual in a violent state may take. Violence is a physical and emotional state which holds various categories of intensity and origins. Bill Buford, in his novel Among the Thugs: The Experience, and the Seduction, of Crowd Violence, describes the experience and observations made of violence, namely within the masses of football teams. The human inclination towards control and dominance is a contributing factor towards most violence. Violence, from my interpretation of Buford's novel, holds its main origins from a spontaneous and irrational desire to establish either control or dominance over a certain event. The potential for spontaneous violence is innate within humans, but humans are not inclined towards violence by itself. The trigger for violence, as Buford notes, can suddenly occur from participation in mass events and the competitive nature of such events (namely, European football in his case.) When such violence is triggered in an individual within such a competitive atmosphere, there is a high chance that the rest of the mass group will follow suit; divisive physical violence (such as pulling or pushing) will cause a chain reaction escalating into a higher level of dangerous violence and a greater risk for potential injury. For example, Buford describes the surges of crowds after a spontaneous violent act (stabbing, in the case of p. 356-358) as creating a wave of irrational actions....

Creatine Research Paper

...Introduction There is a lot of controversy on nutritional supplements and performance/health claims that go along with them. Many claims come and go without a lot of hassle, but none has generated the commotion of the interest or debate surrounding creatine (Cr). Many people believe Cr is another weight gaining powder or steroid alternative (Plisk and Kreider, 1999). What those people do not know is Cr is also found in the human body naturally as opposed to supplementation. Individuals know the name creatine but may not understand the science behind it. The use of Cr has become very widespread, usually in the supplement form Cr monohydrate. Every since the discovery of the ability to increase Cr and phosphocreatine (PCr) inside the human muscles by oral ingestion of supplemental Cr has led to many studies showcasing the benefits of exercise performance. Cr monohydrate supplementation shows significant results to increase the human body’s ability to maintain power output during high-intensity exercise and increase the rate of PCr to resynthesis during the recovery phase of intermittent high intensity exercise (Volek and Kraemer, 1996). My goal is to provide significant information on natural Cr functions, Cr as a supplement, ways the human body utilize Cr to enhance athletic performance, and how society views/uses Cr. Effects of Creatine in the Human Body Creatine was discovered by a French scientist named Chevreul in 1832 but it was not until 1847 did another scientist...

Gwinnett County's close proximity to downtown Atlanta, along with its commitment to expansion of both economic and civic infrastructures, has contributed to its rapid growth. Interstates 85 and 985 traverse the county, as do numerous highways. Created from land ceded by the Chorekee and Creek Indians, Gwinnett was established on December 15, 1818. By 1820 Georgia's forty-fourth county had a population of 4,589. Lawrenceville, the county seat, was incorporated on December 15, 1821, and is the oldest city in the county. Other incorporated cities in Gwinnett are Berkeley Lake, Buford, Dacula, Duluth, Grayson, Lilburn, Norcross, Snellville, Sugar Hill, Suwanee, as well as parts of Auburn, Braselton, Loganville, and Rest Haven. The county was named Button Gwinnett, one of Georgia's three signers of the Declaration of Independence. Farming, particularly, cotton was the main industry, with slave labor contributing to the wealth of the area. The Civil war (1861-65) destroyed much of that economic prosperity but actually caused little physical damage in the county. With the completion of the Southern Railroad in 1871, and the Seaboard Air Line Railroad in 1892, Dacula, Lilburn, and other new towns began to spring up. By...

Michael Shaara's The Killer Angels

...through his eyes was being fought for the good of the country as a whole. Southern states were trying to secede from the United States as a whole and for a way of life and social order, even though it was built upon the conflict of slavery. John Buford, Union Commander of the 1st army to arrive to Gettysburg, a 37 year old who hails from the Midwestern parts of the states, Kentucky. He despises those of the political eastern side of the states and has an incredible talent for discovering the best ground on a battlefield. Buford arrived to Thorofare Gap and placed him and his troops high above ground to attack the confederates. Buford maintained control of keeping them away for over 6 hours until his back up arrived. Soon after his was granted permission to lead two brigades and follow the confederate army around in battle. He excelled in the ability of reading a situation and acting quickly. Aside from his gift he appears to be a loner, and never getting close to anyone. Weapons, Buford used all of them he could; he never turned a blind eye to a single one. The things he brought to this war came from his experience in other wars; he fought in the Indian wars and other civil war battles. Buford was an experienced military man. Buford is not in this war for the terms of slavery, he is fighting more so for patriotism. He feels obligated to fight the war to not be seen as rebel towards his government, therefore, it his duty to be on the battle grounds. Joshua Chamberlain, a 34...

General Hood Research Paper

...76) He eventually died from pneumonia. John Reynolds John Reynolds was setting up his troops for the line of defence to be able to protect themselves and fight for victory at the same time. Out of nowhere the other side(the side they were fighting against) startd to fire. The troops were only partially or almost but not yet ready to take on that battle. Reynolds was on his horse making sure everything was running smoothly and making sure they had enough troops to win and then he was shot. “A moment later Buford looked that way and the horse was barebacked...when buford got there the thick stain had already puddled the dirt beneath his head...He was dead.” (pg.96) As told in the story he was shot off of his horse and immediately died within seconds of being shot. In conclusion, one man's life could have been saved with modern day medicine like General Lee. In Reynolds case their was no way he could have survived that unless he didn't get shot in the head. In the case of Buford he probably would be able to have partial are most feeling back in his arm without a struggle. Anyways, nothing can compare to the hurt and death of the battles fought for us to be free. I can safely say now that knowing how these brave soldiers died has open my eyes and heart to all the troops out here fighting for us today.

Understanding Employee Motivation

...Understanding Employee Motivation James R. Lindner  Research and Extension Associate  The Ohio State University  Piketon Research and Extension Center  Piketon, Ohio  Internet address: lindner.16@osu.edu Introduction to Motivation At one time, employees were considered just another input into the production of goods and services. What perhaps changed this way of thinking about employees was research, referred to as the Hawthorne Studies, conducted by Elton Mayo from 1924 to 1932 (Dickson, 1973). This study found employees are not motivated solely by money and employee behavior is linked to their attitudes (Dickson, 1973). The Hawthorne Studies began the human relations approach to management, whereby the needs and motivation of employees become the primary focus of managers (Bedeian, 1993). Motivation Theories Understanding what motivated employees and how they were motivated was the focus of many researchers following the publication of the Hawthorne Study results (Terpstra, 1979). Five major approaches that have led to our understanding of motivation are Maslow's need-hierarchy theory, Herzberg's two- factor theory, Vroom's expectancy theory, Adams' equity theory, and Skinner's reinforcement theory. According to Maslow, employees have five levels of needs (Maslow, 1943): physiological, safety, social, ego, and self- actualizing. Maslow argued that lower level needs had to be satisfied before the next higher level need would motivate employees. Herzberg's work categorized...

...Project Part 1 Everyone’s Gasoline Price When looking at the history of gas prices they seem to constantly fluctuate over the years. I remember before I was legally able to drive how the gas prices were extremely low. I remember going to fill my mother’s car with her and saw the gas prices were $1.10 a gallon! When I look at gasoline prices now I wonder about what happened to those times now that I am driving. After a little research into the topic I found that there are many different factors that go into the price of gasoline that I never thought about. For example I didn’t realize that gasoline varied from state to state. This is why gas prices are way high in New York and California than they are here in Georgia. In this response I will go over some of these factors as to why gasoline prices vary over the years. Much like anything else that is bought or sold on the market, gasoline is controlled by supply and demand. “If demand grows or if a disruption in supply occurs, there will be upward pressure on prices. By the same token, if demand falls or there is an oversupply of product in the market, there will be downward pressure on prices.” (thepriceoffuel.com) This very much applies to local gas stations as well. For instance if a retailer sells their gas a lot higher than the competition in the area, they run the risk of losing customers to their lower priced competition. In order to gain some of those customers back the retailer would then be forced to lower...
