(HealthDay)—More than half of Americans regularly take about four prescription medications, increasing the likelihood that mistakes could occur, according to Consumer Reports. People taking multiple prescription medications should visit their doctor for a “medication checkup.” By showing their doctor or pharmacist a comprehensive list of every drug they are taking, including vitamins and other dietary supplements, patients can be...

Strength exercise as vital as aerobic new research finds
Doing push ups and sit ups may help you live longer. Push ups and sit ups could add years to your life according to a new study of over 80,000 adults led by the University of Sydney. The largest study to compare the mortality outcomes of different types of exercise found people who did strength-based...

New insights into the release of molecules involved in inflammatory diseases
Image of a biopsy from the intestine of a mouse that has inflammatory bowel disease, a condition in which TNF-mediated inflammation is heavily implicated. In a recent study published in Cell Reports, a research team led by Colin Adrain, from the Instituto Gulbenkian de Ciência (IGC, Portugal), discovered the mechanism that controls the release of...

New link found between gut bacteria and age-related conditions
A new study shows for the first time that gut bacteria from old mice induce age-related chronic inflammation when transplanted into young mice. Called “inflammaging”, this low-grade chronic inflammation is linked to life-limiting conditions such as stroke, dementia and cardiovasuclar disease. The research, published today in open-access journal Frontiers in Immunology, brings the hope of a...

Your bones affect your appetite—and your metabolism
Your skeleton is much more than the structure supporting your muscles and other tissues. It produces hormones, too. And Mathieu Ferron knows a lot about it. The researcher at the Montreal Clinical Research Institute (IRCM) and professor at Université de Montréal’s Faculty of Medicine has spent the last decade studying a hormone called osteocalcin. Produced...

Stem cells pave the way for new treatment of diabetes
415 million people worldwide have been diagnosed with diabetes. And the number continues to rise. Common to all diabetes patients is that they lack the ability to produce sufficient amounts of insulin, which regulates the blood sugar in the body. This can lead to a number of complications and in many cases be potentially fatal....

Inner ear stem cells may someday restore hearing
A stem cell-derived neuron grafted onto a mouse cochlea in the inner ear that lacked neurons. The new neuron is marked red, hair cells that convert sounds into neural signals are green, and hair bundles are blue. Want to restore hearing by injecting stem cells into the inner ear? Well, that can be a...

Differentiation of Human Induced Pluripotent or Embryonic Stem Cells Decreases the DNA Damage Repair by Homologous Recombination
Highlights Spontaneous and S-phase-specific chromosome aberrations in differentiated cells Higher frequency of residual γ-H2AX foci after exposure to DNA-damaging agents Higher frequency of cells with 53BP1 and RIF1 co-localization in differentiated cells Higher frequency of cells with a reduced number of RAD51 or BRCA1 foci Summary The nitric oxide (NO)-cyclic GMP pathway contributes to human...

The secrets of gecko tails could help heal human spine injuries
Geckos are able to regrow their tails by activating a group of stem cells when the tail is lost. Humans tend to think of themselves as the superior species. But the way we heal our bodies is extremely basic: We can (usually) mend our bones pretty well, but if we lose a limb or damage...

Subset of stem cells identified as source for all cells in blood and immune systems
Researchers at Fred Hutchinson Cancer Research Center have identified a specific subset of adult blood stem cells that is exclusively responsible for repopulating the entire blood and immune system after a transplant. The discovery, to be published Nov. 1 in Science Translational Medicine, has the potential to revolutionize blood stem cell transplantation as well as the delivery and...
