Arizona University Scientists Develop Ebola Vaccine

Image
Researchers from Arizona University have developed a vaccine against the deadly Ebola virus that works on mice.

The scientists have found a way to grow and purify the vaccine using the tobacco plant. According to the finding, reported in more detail today at EmaxHealth, the production of the vaccine is inexpensive and could be stored for extended periods without expiring.

The Ebola vaccine is different because it doesn't use a live virus, which means it doesn't require special storage for safety reasons.

The vaccine isn't used to prevent Ebola, but instead provokes the body's immune system to fight the infection.

The next step is to see if the Ebola vaccine works as well humans as it did in mice.


Fish eaters may be lowering their risk of Alzheimer’s disease

Image
For the first time, researchers have found a direct relationship between eating baked or broiled fish and lower risk of Alzheimer’s disease.

Researchers from the University Of Pittsburgh Medical Center and the University of Pittsburgh School of Medicine studied 260 people with no memory problems, finding that eating fish at least once a week seems to preserve gray matter in the brain.
Participants were chosen from the Cardiovascular Health Study.
The investigators used the National Cancer Institute Food Frequency Questionnaire to determine how often the study participants ate fish: 63 patients consumed fish on a weekly basis, and most ate fish one to four times per week.
Advanced 3D MRI, using Voxel-based morphometry was used to measure the volume of gray matter in the brain at baseline and then again 10 years later.
The research team compared gray matter volume among people who ate fish, matching the finding with eating fish. They also adjusted the findings for age, gender, BMI, ethnici…

Avoid jock itch, athlete’s foot and other fungus at the gym

Image
If you enjoy spending time at the gym, chances are you or someone you know has been plagued with some sort of fungus. Jock itch, ringworm and athlete’s foot are spread easily, making it important to take steps to avoid fungus at the gym.
Jock itch causes a raised, red, itchy rash in the groin area. The medical term for jock itch, which can affect women too, is tinea cruris. The best way to avoid the problem is to dry off after a workout and change into loose clothing. Jock itch and other fungi thrive in a moist environment and start from sweating. Make sure you dry off completely after showering.
Athlete’s foot or tinea pedis is easily picked up from wet floors at the gym. The condition usually begins with intense itching between the toes. Without treatment athlete’s foot can spread; causing the skin to peel.
You can avoid athlete’s foot by wearing clean dry socks, avoiding sweaty shoes and wearing shower shoes at the gym. Make sure you wash and dry your feet completely every day. After …

Women report humiliation and stress from cervical smears

Image
A new investigation reveals women interviewed think getting a PAP (cervical smear) test is humiliating and stressful. 
Researchers say a woman’s feelings about cervical smears shouldn't be ignored, and that health care providers should recognize and discuss expectations and anxiety women might experience from the tests.
In findings from University of Leicester, published in the international journal Family Practice, women report they aren’t always treated kindly when they have their exam to detect cancer.
In their study, the researchers found women would like a more personalized approach.
According to Dr Natalie Armstrong, Lecturer in Social Science Applied to Health at the University of Leicester:
"Attitudes towards cervical smears remain something of a paradox. On one hand, screening appears to command impressive levels of public support - as demonstrated by campaigns to widen the eligibility criteria - but on the other hand there is considerable evidence suggesting that individ…

CDC report highlights overdose deaths from prescription painkillers

A new report from the CDC highlights the problem of overdose and death from prescription painkillers. According to the CDC, physicians, consumers and policy makers can act together to ensure patients receive safe pain management.


According to the finding, A large portion of overdose deaths are the result of people taking the medications recreationally. According to the CDC, in 2010, 12 million Americans over age 12 said they took painkillers in the past year just to get high, rather than for medical purposes.


The report also found more men than women die from drug overdose from prescription painkillers that include oxycodone, methadone and hyrdocodone.

Surgeon removes eight pound, foot long tumor from man’s liver

Image
Man turned away by 3 surgeons
Marcus Muhich had a tumor in his liver that weighed 8 pounds and was a foot long. He had been turned down by three surgeons who said his tumor was inoperable.
The man was ultimately referred to a surgeon at Loyola University.
It’s now been two years since Dr. Margo Shoup, chief of the Division of Surgical Oncology at Loyola University Medical Center removed Mr. Muhich’s tumor. He is cancer free and calls Dr. Shoup a “miracle worker”.
The tumor was so large it was pressing against the man’s vena cava – a major artery that supplies blood flow to the heart. Three surgeons at major academic hospitals told Muhich the tumor couldn't be removed.
Because the cancerous liver tumor was pressing on the man’s vena cava, he was having an irregular heartbeat known as atrial fibrillation.
The 8 pound tumor was felt by a cardiologist when Muhich sought care for his heart rhythm disturbance.
Dr. Shoup was able to determine the cancer had not spread, even though it was …

Top College Health Issues

College can have a negative effect on health

Many students find starting college has a negative effect on their health. Between socializing and keeping up with classes online they become too busy to eat right or sleep well. College students face new levels of stress about tests and project deadlines.

 In addition, contagious illnesses spread much faster in the relatively close quarters of college campuses. Students should be aware of the biggest health issues they face, and follow the recommendations below to stay healthy.

Stress is a primary concern for college students
Stress and anxiety are primary concerns as students become anxious over grades, adjusting to a new life on campus, and making new friends. They may become depressed and even have suicidal thoughts. College campuses' student health offices can advise on how to deal with specific issues, and help students find counseling if necessary. For any stress level, exercise helps to release endorphins, a feel-good hormone and…

Marijuana use might double the chances of driving accidents

Image
Marijuana use linked car accidents
Research suggests if you use marijuana you may be at twice the risk of having a motor vehicle accident, compared to people who don’t use cannabis.
Researchers at Columbia University performed a meta-analysis of nine epidemiologic studies, finding people who tested positive for marijuana were twice as likely to have a car accident. The chances of a mishap while driving increased with frequency of marijuana use and concentration of the drug in the urine.
The scientists say the finding is important because of findings from a 2009 National Survey on Drug Use and Health that showed over 10 million people age 12 or older had driven under the influence of an illicit drug in the year prior to the survey.
Guohua Li, MD, DrPh, professor of Epidemiology at Columbia University's Mailman School of Public Health, and senior author says the finding should be interpreted with caution, because the research doesn’t prove cause.
Marijuana most frequently found drug lin…

In a down economy, nursing jobs thrive

Today's economy is not the best for many people looking for employment. If you are considering a certification for nursing assistance, are in school for a nursing degree, or already have a nursing degree but have not yet found a job, you may be wondering if available nursing jobs decreasing. 
Although some hospitals and clinics are experiencing budget cuts like many other organizations, even in the worst of times, healthcare positions are always a priority. 
ABC news has reported that there is a dire need for nurses, so much so that larger sign-on bonuses are often offered. A huge portion of the population needs health care at any given time. Doctors, nurses, pharmacists, X-ray technicians, and others will be able to find employment within the range of their profession.
Hospitals, clinics and nursing homes are trying to cut costs in order to stay in business, but they are required to have a specific number of required personnel on duty at all times in order to pass their standardizat…

Synthetic compound SRT1720 helps obese mice live longer

Image
Researchers are testing the effect of a synthetic resveratrol stimulator, known as SRT1720 to see if it might treat human diseases, reverse metabolic syndrome and help people live longer. In mouse studies, the compound did just that.

The compound has been suggested to have anti-aging properties from past studies.
SRT1720 activates a class of enzymes known as sirtuins, which are associated with the same positive health effects as calorie restriction.
In obese mice, scientists found improved liver, heart and pancreas function, compared to mice not given the patented compound.
The study is a collaborative effort of the National Institute on aging (NIA) and the drug company Sirtris, a GlaxoSmithKline company, and is published in the August 18, 2011, issue of Scientific Reports.

Second-hand smoke implicated for adolescent hearing loss

Image
Secondhand (SHS) smoke has received a significant amount of attention for harming health. Now a study shows adolescents exposed to SHS are at increased risk for hearing loss, in addition to other health issues that include respiratory ailments, behavior problems and low birth weight. 

The finding, published inthe July issue of Archives of Otolaryngology–Head and Neck Surgery, one of the JAMA/Archives journals, cites statistics that 60 percent of children are exposed to secondhand smoke in the United States.

How second hand smoke leads to hearing loss in youth The link is seen from recurrent ear infections, or otitis media. The chance of ear damage and sensorineural hearing loss (SNHL) increased with higher levels of exposure to secondhand smoke in adolescents studied.
The authors says hearing loss may occur from "suppression or modulation of the immune system" or from "impairment of the respiratory mucociliary apparatus" that would normally act as a defense against ba…

Stored blood for transfusion becomes less safe with aging, finds new study

Image
New research shows current methods of storing blood may be unsafe. Findings from scientists at Wake Forest University and the University of Pittsburgh School of Medicine found some complications associated with blood transfusion comes from the breakdown of red blood cells that happens during storage.


The finding means it may be necessary to find new ways to preserve blood for transfusion.


According to background information from the study, someone in the United States needs a blood transfusion every two seconds.


The finding, published in the journal Circulation, found nitric oxide (NO) interacts with stored red blood cells, breaking down blood flow. For transfusion recipients, vital tissues can be damaged from blood stored for long periods of time.


Higher rates of infection risk, kidney, lung or multi-organ failure and death have been observed among patients given transfusions from blood stored for longer periods of time, leading the researchers to try to understand why.


Stored blood can r…

Study: Bigger forks stop diners from ‘pigging out’

Image
When it comes to the battle of the bulge, new research shows simply using a bigger fork stopped restaurant diners from 'pigging out'. Using a bigger fork helped diners eat less in an experiment.


According a July 14. 2011 news release, putting a bigger bite of food on your fork leads to less eating from important visual cues that otherwise seemed to be overlooked by food consumers.

The finding, which appears in the Journal of Consumer Research, is an interesting note for women who may not find a big fork so delicate.
But for weight loss, a bigger fork gives visual cues that could help with setting goals.
The study authors, from University of Utah, Salt Lake City, write: "The fork size provided the diners with a means to observe their goal progress. The physiologicalfeedback of feeling full or the satiation signal comes with a time lag. In its absence diners focus on the visual cue of whether they are making any dent on the food on their plate to assess goal progress."
