Texas A&M study shows 'bad' cholesterol not as bad as people think

The so-called "bad cholesterol" - low-density lipoprotein commonly called LDL - may not be so bad after all, shows a Texas A&M University study that casts new light on the cholesterol debate, particularly among adults who exercise.

Steve Riechman, a researcher in the Department of Health and Kinesiology, says the study reveals that LDL is not the evil Darth Vader of health it has been made out to be in recent years and that new attitudes need to be adopted in regards to the substance. His work, with help from colleagues from the University of Pittsburgh, Kent State University, the Johns Hopkins Weight Management Center and the Northern Ontario School of Medicine, is published in the Journal of Gerontology.

Riechman and colleagues examined 52 adults from ages to 60 to 69 who were in generally good health but not physically active, and none of them were participating in a training program. The study showed that after fairly vigorous workouts, participants who had gained the most muscle mass also had the highest levels of LDL (bad) cholesterol, "a very unexpected result and one that surprised us."

Evidence Shows the Advent of Agriculture was Bad News for our Health

Yesterday I had a email from a friend alerting me to an interesting piece in the Sunday Times. I went out especially to buy a copy. The piece, entitled 'Farmers, you've shrunk mankind', is based around presentation given at the Royal Society in London, last week. The lecture was delivered by Dr Marta Lahr of the Leverhulme Centre for Human Evolutionary Studies at Cambridge University, UK. It seems that the fossil record shows our ancestors 200,000 years ago to be about 10 per cent bigger and taller than we are now. And 20,000-30,000 years ago, our ancestors had brains about 10 per cent bigger than ours are now too.

A shrinking in the size of our bodies and brains happened about 10,000 years ago. What was it that caused this? The answer is our transition from hunter-gathering to a more farming-based existence.

The Sunday Times piece also relates research from Amanda Mummert, an anthropologist from Emory University in Altanta, US. Mummert has recently co-authored a paper [1] which provides evidence supporting the idea that our move to agriculture was bad news for our height and our health. One of the reasons that would explain this, according to Mummert, is an over-reliance on a grain-based diet deficient in key nutrients. Sound familiar anyone?

Study shows that preschool-age children who got less sleep were more likely to be hyperactive and inattentive in kindergarten.

Short sleep duration may contribute to the development or worsening of hyperactivity and inattention during early childhood, suggests a research abstract that will be presented Tuesday, June 14, in Minneapolis, Minn., at SLEEP 2011, the 25th Anniversary Meeting of the Associated Professional Sleep Societies LLC (APSS).

Results show that less sleep in preschool-age children significantly predicted worse parent-reported hyperactivity and inattention at kindergarten. In contrast, hyperactivity and inattention at preschool did not predict sleep duration at kindergarten. The sample consisted of approximately 6,860 children, and analyses controlled for gender, ethnicity and family income.

"Children who were reported to sleep less in preschool were rated by their parents as more hyperactive and less attentive compared to their peers at kindergarten," said lead author Erika Gaylor, PhD, senior researcher for SRI International, an independent, nonprofit research institute in Menlo Park, Calif. "These findings suggest that some children who are not getting adequate sleep may be at risk for developing behavioral problems manifested by hyperactivity, impulsivity, and problems sitting still and paying attention."

Average Drug Label Lists Over Whopping 70 Side Effects

Using a computer program, scientists analyzed 5,600 drug labels and more than 500,000 labeled effects. They found that the average drug comes with a list of 70 potential reactions, according to researchers.

In fact, the more commonly prescribed drugs averaged around 100 side effects each, with some drugs containing as many as 525 listed reactions.

MSNBC reports:
"The greatest number of side effects was found in antidepressants, antiviral medications and newer treatments for restless leg syndrome and Parkinson's disease. In general, medications typically used by psychiatrists and neurologists had the most complex labels, while drugs used by dermatologists and ophthalmologists had the least."

Study finds that treatment with frontal cerebral thermal transfer can eliminate insomnia symptoms.

People with primary insomnia may be able to find relief by wearing a cap that cools the brain during sleep, suggests a research abstract that will be presented Monday, June 13, in Minneapolis, Minn., at SLEEP 2011, the 25th Anniversary Meeting of the Associated Professional Sleep Societies LLC (APSS).

According to the authors, a reduction in metabolism in the brain's frontal cortex occurs while falling asleep and is associated with restorative sleep. However, insomnia is associated with increased metabolism in this same brain region. One way to reduce cerebral metabolic activity is to use frontal cerebral thermal transfer to cool the brain, a process known as "cerebral hypothermia."

Results show that there were linear effects of all-night thermal transfer intensities on sleep latency and sleep efficiency. The time that it took subjects with primary insomnia to fall asleep (13 minutes) and the percentage of time in bed that they slept (89 percent) during treatment at the maximal cooling intensity were similar to healthy controls (16 minutes and 89 percent).

"The most significant finding from this study is that we can have a beneficial impact on the sleep of insomnia patients via a safe, non-pharmaceutical mechanism that can be made widely available for home use by insomnia sufferers," said principal investigator and lead author Dr. Eric Nofzinger, professor and director of the Sleep Neuroimaging Research Program at the University of Pittsburgh School of Medicine. "The finding of a linear dose response effect of the treatment implies a direct beneficial impact on the neurobiology of insomnia that can improve the sleep of insomnia patients. We believe this has far-ranging implications for how insomnia can be managed in the future."

India: City Falls Prey to Viral Fever Outbreak

Viral Attack

Kolkata: The city is in the grip of a viral fever that has affected thousands, including many in Ballygunge, Alipore and parts of central Kolkata. It has been leading to high fever accompanied by a severe lung and chest infection, often causing severe respiratory problems. Experts have been taken by surprise by the late outbreak of this viral epidemic which usually occurs during change of seasons.

The new virus is far more potent and different from the ones that have struck in previous years, said doctors. "This one has been attacking the respiratory system which makes it more risky. Patients have been suffereing from severe breathlessness along with an intense joint and muscle pain. Many are also falling prey to secondary bacterial infections.

There have been several cases where malaria has been detected in these patients as well," said Tomonash Bhattacharya, tropical medicine expert. Typical symptoms of the viral attack has been a dry cough, followed by high fever and joint pain. From the third day onwards, patients have had a severe lung congestion with respiratory trouble. The fever has not been subsiding before a week leaving victims too frail to resume normal activities. "It is the reactive phenomenon that has been causing the joint and muscle pain. Anti-bodies triggered to fight the virus is responsible for this.

The government should consider evacuating children and pregnant women from a wider area around the Fukushima No. 1 power plant because radiation levels remain high even outside the 20-km no-go zone, Kumi Naidoo, executive director of Greenpeace International, said Thursday in Tokyo.

Naidoo's team of radiology experts found hot spots that had a maximum hourly reading of 45 microsieverts of radiation alongside a school zone.

While the area likely had high levels of radiation as a result of the landscape or other natural conditions, Naidoo insisted the central government should conduct thorough checks and provide accurate and fast information to local residents.

In a study funded by the American Lung Association researchers studied several hundred metabolites of 19 patients divided into groups of smokers and non-smokers. They found a significant difference in the metabolites in smokers and non-smokers.

"This gives us an idea of how people produce metabolites differently when smoking cigarettes, which is based on their particular genetic profile and other biological and environmental factors," says researcher Ping-Ching Hsu, who is a doctorial student and lead investigator in the study.

The ultimate goal of the research is to define the metabolomic profile or "metabolome" that might predict who may be most likely to develop disease from smoking, as well as more clearly define how smoking causes that disease. "Metabolomics provides a broad picture of what is happening in the body of smokers," Hsu says. In further research Hsu studied how heavy smoking affects the metabolome verses light smoking and found several biological pathways could be changed.

  • Scientists create breast milk produced by cows
  • Special cow herd created with human genes
  • Expected to hit supermarkets in three years
Chinese scientists have genetically modified dairy cows to produce human breast milk, and hope to be selling it in supermarkets within three years.

The milk produced by the transgenic cows is identical to the human variety, with the same immune-boosting and antibacterial qualities as breast milk, scientists at China's Agricultural University in Beijing said.

The transgenic herd of 300 was bred by inserting human genes into cloned cow embryos which were then implanted into surrogate cows, Sky News reported.

The technology used was similar to that used to produce Dolly the sheep, the first mammal to be cloned by scientists, in Scotland.

The milk is still undergoing safety tests, but with government permission will be sold to consumers as a more nutritious dairy drink than cow's milk.

Workers at the university's dairy farm have already tasted the milk - and said it is sweeter and stronger than the bovine variety.

Scientists have uncovered a trio of genes tied to migraine headaches, including one in which the link is exclusive to women, according to a study published Sunday.

Migraines are acutely debilitating headaches -- sometimes with an "aura", in which patients have the impression of seeing through frosted glass -- that strike up to 20 percent of the population.

Scientists describe the condition, which is three to four times more common in women, as a brain disorder in which neurons, or brain cells, respond abnormally to stimuli.

The precise cause it unknown, but inheritance is thought to play a significant role.

To assess the genetic component, Markus Schuerks of Brigham and Women's Hospital in Boston coordinated an international sweep of genomes in 23,230 women, 5,122 of whom suffered from migraines.

Comment: While there may be certain genetic dispositions to migraine headaches, the one thing they leave out in this article is that foods have the ability to alter gene expressions too. Many have found migraines to be the result of hidden food allergies or food sensitivities. For further reading see:
