Previous UCSF Research Found Overall Reduction in Spine Fractures, But Not for Other Types of Fractures Continuing a popular but controversial treatment for osteoporosis could reduce spine fracture risk for a particular group of patients, but others could see little to no change if they discontinue it. Based on available evidence, a UCSF researcher reevaluated his 2006 finding from a randomized 10-year study of alendronate, a type of bisphosphonate — a class of drugs that prevent...

Biomedical engineers at Tufts University's School of Engineering have demonstrated the first all-polymeric bone scaffold material that is fully biodegradable and capable of providing significant mechanical support during repair. The new technology uses micron-sized silk fibers to reinforce a silk matrix, much as steel rebar reinforces concrete. It could improve the way bones and other tissues are repaired following accident or disease. The discovery is reported in the Proceedings of the...

(Ivanhoe Newswire) -- Vitamin D is known for helping create strong bones and is a key regulator of serum calcium levels. Recent studies, however, have not offered much proof that Vitamin D supplements prevents bone fractures. Calcium is obtained through diet and absorbed through the intestine and into the blood stream. Calcium is responsible for a variety of physiological processes, not just building bone. Vitamin D is detected by bone and intestinal cell receptors and it regulates the...

(Ivanhoe Newswire) — Biology Major Adam Reese may have found the key to keep fat cells from forming. While investigating new ways to combat osteoporosis, with Assistant Professor Anja Nohe, in the University of Delaware science lab, Reese discovered a trigger that he believes turns a stem cell into a fat cell. The trigger, a protein called endoglin, regulates what type of cell an existing stem cell will become. Reese, with the help of graduate student Joyita Dutta, found the amount...

Here's an anatomical packing list for making that historic trip from water to land circa 370 million years ago: Lungs? Check. Legs? Check. Patches of highly vascular bone in the skin? In a new paper, scientists propose why many of the earliest four-legged creatures that dared breathe on land carried bony skin features. The "dermal bones" within the skin, especially the bones covering the skull roof and forming part of the shoulder girdle, had a highly complex surface of ridges and furrows...

UD research identifies a protein that regulates the creation of fat cells Biology Major Adam Reese may have found the key to keep fat cells from forming. The University of Delaware junior believes he has identified the trigger that turns a stem cell into a fat cell. Located on the surface of cells, the trigger, a protein called endoglin, regulates what type of cell an existing stem cell will become. Working in the biological science department's laboratory of cellular signaling and...

'Inhabitants Of Madrid' Ate Elephants’ Meat And Bone Marrow 80,000 Years Ago

Humans that populated the banks of the river Manzanares (Madrid, Spain) during the Middle Palaeolithic (between 127,000 and 40,000 years ago) fed themselves on pachyderm meat and bone marrow. This is what a Spanish study shows and has found percussion and cut marks on elephant remains in the site of Preresa (Madrid). In prehistoric times, hunting animals implied a risk and required a considerable amount of energy. Therefore, when the people of the Middle Palaeolithic (between 127,000 and...
