A fibroblast is not always just a fibroblast "“ particularly in the heart. In a heart attack, fibroblasts "“ special repair cells that form a scar after injury "“ come from a population of stem cells that reside within the heart, said researchers from Baylor College of Medicine and the Methodist Hospital in a report that appears in the journal Cardiovascular Research. By contrast, earlier work showed that the fibroblasts responsible for fibrosis "“ excess fibrous...

Introducing: A guide to improving the care of patients Many Baby Boomers will experience a bone fracture as they age, and the current US healthcare system is not prepared to provide the necessary care required, according to a special monograph released in the January 2011 issue of Geriatric Orthopaedic Surgery and Rehabilitation (GOS), published by SAGE. The first members of the post World War II Baby Boom generation will reach 65 years old this year. The Baby Boomers encompass an estimated...

New research shows that the Wnt receptor Frizzled-9 (Fzd9) promotes bone formation, providing a potential new target for the treatment of osteoporosis. The study appears online on March 14 in The Journal of Cell Biology (www.jcb.org). Adult bones are maintained by a balance of bone-forming osteoblasts and bone-resorbing osteoclasts. Although Wnt signaling affects this balance in mice and humans, the Wnt receptors involved remain unknown. A team of researchers led by Thorsten Schinke found...

Postmenopausal women have a new health message to hear. Two annual dental checkups aren't enough. Older women need more, according to research findings from the Case Western Reserve University School of Dental Medicine and the Cleveland Clinic. That message comes from a comparison study of women on and off bone-strengthening bisphosphonate therapies for osteoporosis. Leena Palomo, assistant professor of periodontics from the dental school, and Maria Clarinda Beunocamino-Francisco from the...

Technology offers new options for patients undergoing bone grafts for foot, ankle conditions FORT LAUDERDALE, Fla., March 11, 2011 /PRNewswire/ -- When patients need a bone graft for a foot or ankle surgery, bone often is taken from another part of their body. Now surgeons are using new methods to get bone material and even stem cells right "off the shelf," according to Glenn M. Weinraub, DPM, FACFAS, a California foot and ankle surgeon who is leading a discussion among surgeons on the...

By: Rhonda Craig, Ivanhoe Health Correspondent (Ivanhoe Newswire) -- The same medicines used to treat angina and chronic heart failure, may also help treat osteoporosis. In this new study, researchers found that postmenopausal women that used nitroglycerin ointment for two years experienced a modest increase in bone mineral density and decrease in bone loss. According to study authors, the number of osteoporotic fractures is increasing, and an inexpensive and widely available treatment like...

However, the drugs do prevent hip fractures Women who take commonly prescribed drugs for osteoporosis known as bisphosphonates for five years or more may be at higher risk of certain kinds of fractures of their thigh bone, a new study has found. However, the drugs do prevent hip fractures. And, since the overall risk of thigh bone fractures caused by the drugs is low, women at high risk for hip and other osteoporosis-related fractures should not stop taking bisphosphonates, according to...

Older women who used bisphosphonates (medications that prevent loss of bone mass) for five years or more were more likely to experience "atypical" fractures involving the femoral shaft (bone in the leg that extends from the hip to the knee) or subtrochanteric (fractures in the bone just below the hip joint), compared to women with less usage. However, the absolute risk of these "atypical" fractures was low and bisphosphonate use was associated with a reduced risk of typical osteoporotic...

Preliminary research indicates that use of nitroglycerin ointment among postmenopausal women for 2 years was associated with a modest increase in bone mineral density and decrease in bone resorption (loss), according to a study in the February 23 issue of JAMA. "The number of osteoporotic fractures is increasing worldwide as populations age. An inexpensive and widely available treatment may help limit this increase," the authors write. "Nitroglycerin stimulates bone formation and inhibits...

Researchers have discovered an unexpected connection between a hormone produced in bone and male fertility.  The study shows that the skeletal hormone known as osteocalcin boosts testosterone production to support the survival of the germ cells that go on to become mature sperm. The researchers said the findings, which were reported in the February 18th issue of Cell, provide the first evidence that the skeleton controls reproduction through the production of hormones. According to...
