More Effective Than Low Cal Diet

1 Curbing Carbs Quickly Reduces Fat in Liver

If your doctor tells you to reduce the amount of fat in your liver, you can do it within a month, says Dr. Jeffrey Browning, lead author of a new study. The results could have implications for treating diabetes and fatty liver disease, the latter of which affects as many as one-third of American adults. The study found that curbing carbs is more effective at reducing fat in the liver than cutting calories and that results may be noticed in as little as two weeks. Study participants lost an average of 10 pounds in two weeks on the low-carb diet. Dr. Browning cautioned that “weight loss, regardless of the mechanism, is currently the most effective way to reduce liver fat,” and that a low-carb diet is not fundamentally better than a low-fat one in the long run.

Think About It

2 Seeing Overweight People Encourages Overeating

Does being in the presence of an overweight person cause us to overeat? Research indicates that just seeing a heavy person “leads to a temporary decrease in a person’s own felt commitment to his or her health goal,” say the authors of a new study. For the study, participants were asked to do a cookie taste test. After seeing an overweight person, participants ate twice as many cookies, even if they had a weight goal and recognized that cookies lead to weight gain. Researchers identified two main strategies to offset the tendency to overeat in the presence of overweight people: being conscious of weight goals and recognizing the link between overeating and weight gain. "Thinking about personal health goals ... can help people avoid eating too much," say the authors.

Air Traffic Control Mishap

3 Plane Carrying Michelle Obama Aborts Landing

In what may be another air traffic controller mistake, the plane carrying Michelle Obama had to abort its landing after getting too close to a military C-17 cargo plane, confirms CNN. The First Lady was flying in a C-40, a military version of a 737. Both planes were attempting to land, but there should have been at least five miles between them. The planes were only three miles apart. The FAA said that controllers at the Andrews Air Force Base told the incoming Boeing 737 to "go around" since it didn't have the "required amount of separation" following the C-17. The plane carrying Michelle Obama had to circle before landing, but officials say that her life was never in danger. The FAA says that they didn't want Obama's plane to get caught in the "jet wash" of the landing C-17.

Is That a Flower or Vagina?

4 O'Keeffe Art is Sexier to Fertile Women

Women in the fertile half of their menstrual cycles viewed Georgia O'Keeffe's flower paintings as more sexy than when they were in the less-fertile second half of their cycles, say researchers from Muhlenberg College in Pennsylvania. The findings, published in Archives of Sexual Behavior, also reveal that women on birth control pills that suppress ovulation saw the suggestive flower paintings as consistently erotic throughout the month. Study researcher Jeffrey Rudski says that the findings support an evolutionary psychology approach to sexuality: Women are more interested in sex during more fertile times of the month.

Decreases Pain Symptoms

5 Peppermint Could Help Irritable Bowel Syndrome

About 10 to 20 percent of the population suffers from Irritable Bowel Syndrome, a gastrointestinal disorder that causes abdominal pain, bloating, and changes in bowel habits including diarrhea and constipation. Women are twice as likely as men to suffer the debilitating condition, brought on by food poisoning, stress, medication reaction or genetic causes. Researchers from the University of Adelaide have found that peppermint may activate the TRPM8 channel in the colon, reducing inflammatory pain activated by fatty and spicy foods. While the remedy has been used by naturopaths for years, this is the first mainstream clinical study to show the effectiveness of peppermint preparations, says study leader Dr. Stuart Brierley, who published the findings in the journal Pain.

Obesity a Factor

6 Fatty Liver Can Increase Heart Attack Risk

About 30 million Americans have non-alcoholic fatty liver disease, or NAFLD. Because of the prevalence of obesity, more Americans are expected to develop the condition, which can increase the risk of coronary artery disease. People with fatty liver disease are more likely to die from a heart attack, says Dr. Howard Monsour, chief of hepatology at The Methodist Hospital in Houston, Texas. NAFLD, fat inside the liver cells, is caused by lipid disorders, diabetes, obesity, alcohol and drugs. Those with the condition are more likely to have metabolic syndrome, a cluster of factors which increase the risk of heart attack and stroke. Diet and vigorous exercise can help aid weight loss. Just a 12 percent decrease in weight can eliminate liver fat, says Dr. Monsour.

Alters Lung Development

7 "Thirdhand Smoke" Dangerous to Young Lungs

Research at UCLA has determined that “third-hand smoke,” tobacco toxins on surfaces such as furniture, clothing and other surfaces anywhere someone has smoked, is detrimental to the lungs of unborn babies. The mechanisms involved in normal lung development are impaired and if that happens in the womb, respiratory problems such as asthma can result. Exposure mostly occurs by touching contaminated items and ingesting the very fine particles, with babies ingesting two times as much as adults which leaves them more prone to problems. It was also noted that non-smoking households had one–sixth the level of nicotine compared to smoking households. Fetal lungs are more susceptible to the effects of the compounds NNA and NNK from thirdhand smoke than those of babies and children.

Disrupts Inflammatory Pathway

8 Antibody Reduces Damage Due to Ischemic Events

Research at the University of Leicester shows an injection of an antibody disrupts the inflammatory tissue response that occurs after an ischemic event such as a heart attack or stroke. In animal studies, one injection of an antibody against the enzyme Mannan Binding Lectin-Associated Serine Protease-2 (MASP-2) reduce the damage caused by disruptions in blood flow the prevent oxygen from getting to tissues and yielded better outcomes. MASP-2 is involved in the lectin pathway which plays a role in innate immunity and is activated during an ischemic event such as a heart attack or stroke. Patients who have surgeries where blood flow had to be interrupted such as transplants may also benefit from this injection. Researchers are currently preparing to conduct human clinical trials.

DNA Repair Inhibited

9 Link Between Inflammation and Cancer Explained

Researchers at Ohio State University have discovered how inflammation might cause cancer. When there is inflammation, a molecule called microRNA (miR-155) increases and inhibits the expression of genes that make proteins that repair damaged DNA. Several studies have shown that inflammation can lead to cancer. One example is inflammatory bowel disease (IBD) increasing the risk of colorectal cancer. Spontaneous DNA damage is always occurring and most of the time repair mechanisms fix the damage but when DNA cannot be repaired the number of mutations increase and ultimately can lead to carcinogenesis. One potential treatment for cancers due to inflammation is to develop inhibitors of miR-155 which has been linked to different types of leukemia, breast, lung and gastric cancers.

A Few Weeks Makes a Difference

10 Premature Birth Linked to Greater ADHD Risk

A Swedish study suggests that the more premature a baby is, even by a few weeks, the greater the odds of being prescribed an ADHD drug. Searching a database that included over 1,000,000 children 6 to 19 years old found that 7,506 received a prescription for the condition which makes paying attention and impulse control difficult. Kids born between 23 and 28 weeks had the greatest risk of developing ADHD which was two and a half times that of those born full term. Researchers found that 15 out of 1,000 kids born very prematurely got a prescription compared to six out of 1,000 born at 39 to 41 weeks. For kids born at 37 to 38 weeks, seven out of every 1,000 was prescribed medication. Even after all other factors are considered, premature birth was still strongly linked to ADHD.

Allows for Intervention

11 Blood Test May Predict Premature Birth

A study published in the May issue of the American Journal of Obstetrics & Gynecology shows that three peptide biomarkers plus some other proteins in the blood can be used to determine if a woman is likely to give birth prematurely. Premature birth is associated with a lot of health problems, both right after birth and on into childhood. Eighty women who gave birth to full term babies and 80 who gave birth prematurely had a drop of blood sampled. The results suggested that 80 percent of premature births could be detected in the second trimester. Having this knowledge could allow a woman and her doctor develop a plan of action in terms of how active she should be, if she should travel or even receive hormones that can delay labor.

Melanoma Metastasis Markers

12 Blood Biomarkers May Tell if Melanoma Will Spread

Elevated biomarkers in plasma could possibly predict the chance that melanoma that has spread, based on results from a study of 216 people. Of the participants, 108 had metastatic melanoma and another 108 had stage 1 or 2. Seven biomarkers, CEACAM, ICAM-1, osteopontin, MIA, GDF-15, TIMP-1 and S100B were elevated in those with advanced melanoma. People with melanoma are subject to a battery of tests that include imaging, blood test and physical exams, but no one knows how often they should be done and how reliable the results are. Studies in patients with early stage melanoma have to be conducted to confirm that the test accurately predicts whether the cancer will spread. Melanoma is the deadliest form of skin cancer; it was diagnosed in 68,130 Americans and killed 8,700 last year.

The Amazing Spider-Mongolian

13 Researchers Find Largest Spider Fossil on Earth

An ancient spider fossil was recently discovered in Inner Mongolia and researchers are reporting that it is the largest ever found. The female arachnid lived about 165 million years ago and belongs to a family of spiders known as the Golden Orb Weavers. Researchers are calling the specimen Nephila jurassica, and have concluded that the spider would have had a leg span of 15 centimeters. The fossil dates back to the Jurassic Period and is the oldest Nephila species ever found. Researchers don't know how the spider died, but have guessed that she was encased in erupted volcanic ash that pulled her from her web and smothered her. No matter what caused her demise, researchers can definitely agree that they are extremely lucky to have found such an amazingly well-preserved and unique fossil.
