Between 2006 and 2008, researchers assessed the cardiorespiratory (heart/lung) fitness of just over 4,500 men and women in Norway. None had heart disease, high blood pressure or cancer, and most were considered at low risk for heart disease over the next 10 years. By 2017, however, 147 of the study participants had suffered a heart attack or developed angina, conditions caused by narrowing or blockage of heart arteries. More investigation showed that the risk of heart attack and angina … [Read more...]
Does salamander hold key to regrowing human body parts?
Scientists who assembled the genome of a salamander renowned for its ability to regenerate body parts say the achievement could be an important step toward finding ways to regrow human body parts. The axolotl is a salamander whose only native habitat is a lake near Mexico City. "It's hard to find a body part they can't regenerate: the limbs, the tail, the spinal cord, the eye, and in some species, the lens, even half of their brain has been shown to regenerate," said study co-lead author … [Read more...]
Ancient Aztec ‘superfood’ could lower blood pressure, study says
A food source consumed by the Aztecs until the 16th century could bring new hope for people with high blood pressure, a study says. The findings, published in the journal Hypertension, showed that isolated peptides known as SP6 lowered the blood pressure of hypertensive animals in lab experiments. "Our research started by conducting simulated gastrointestinal digestion on the raw extract of spirulina. In other words, we reproduced what happens in the human gut after ingesting the … [Read more...]
Marijuana use doesn’t increase conduct problems in teens
Teens with behavioral problems are more likely than others to use marijuana -- but the drug itself doesn't increase conduct problems, a new study indicates. The findings suggest that a "cascading chain of events" predict marijuana use problems as teens become young adults, according to the University of Pennsylvania researchers. "Cannabis use in and of itself does not appear to lead to conduct problems or increasing attraction to peers who use cannabis," said study co-author Dan Romer, a … [Read more...]
Women reluctant to take preventive breast cancer drug
Many British women won't take a drug that could prevent the development breast cancer over side effects concerns, a study says. Researchers from the University of Leeds in the UKpublished the findings Monday in the journal Clinical Breast Cancer. "Women in our study were rightfully considering the potential harms and benefits of using preventive therapy," Samuel Smith, a researcher at the University of Leeds and lead author of the study, said in a press release. "But some beliefs about the … [Read more...]
20 years after settlement, billions in anti-tobacco funds spent elsewhere
Twenty years after 46 states and the District of Columbia reached a historic settlement with four major tobacco companies, the United States has seen an unprecedented drop in adult smoking. But advocates say the billions paid to states are not always being targeted for smoking cessation. The 1998 agreement established a fund in which tobacco companies -- Philip Morris, R.J. Reynolds, Brown & Williamson and Lorillard, as well as industry trade associations -- pay states billions annually … [Read more...]
Opting for organic foods may reduce risk for some cancers
Paying extra for those pricey organic fruits and vegetables might pay off: New research suggests eating them might help you dodge a cancer diagnosis. People who consumed the most organic foods had a 25 percent lower cancer risk compared with those who ate the least, the study found. Specifically, eating more organically grown foods was linked to a 34 percent reduced risk of postmenopausal breast cancer, a 76 percent decreased risk for all lymphomas and an 86 percent reduced risk for … [Read more...]
Experimental vaccine may reduce risk of post-stroke blood clot
An experimental vaccine reduced the risk of post-stroke blood clot risk in a study with mice, researchers report in a new study. Researchers in Japan hope the vaccine, called S100A9, may one day replace oral blood thinners, which are used to help prevent another stroke. The findings were published Monday in the journal Hypertension. In addition, they found that the vaccine also doesn't increase the risk of serious bleeding or lead to an autoimmune response. "Many stroke patients don't … [Read more...]
Bug behind stomach cancer also linked to colon cancer
The same type of bacteria that causes stomach cancer may also increase colon cancer risk, especially in black Americans, a new study finds. Researchers analyzed data from more than 4,000 colon or rectal cancer cases in the United States. They found a significant association between rates of these cancers and infection with a virulent strain of H. pylori bacteria that's especially common among black Americans. The findings do not prove that H. pylori causes colon or rectal cancer, however. … [Read more...]
Squeezing pimples could make acne worse
It may be tempting to squeeze a large pimple, but doing so could make the zit worse, skin doctors say. Up to 50 million Americans struggle with various forms of acne, particularly red, swollen, painful bumps that develop deep in the skin, according to the American Academy of Dermatology. There are better, more effective ways to manage acne, said board-certified dermatologist Dr. Meghan Feely. "Although there are no overnight or immediate cures for acne, you don't have to stand by and … [Read more...]
