Pycnodysostosis sheds light on enzyme's role in bone metabolism

Pycnodysostosis, a condition from which the painter Henri de Toulouse-Lautrec suffered, is a genetic disease characterized by short stature.

Laser treatment works well on sun-damaged skin

Researchers in the United States have found that sun-damaged skin responds well to laser treatment - which is good news for people with skin badly damaged by exposure to the sun.

Sun-damaged skin responds well to laser treatment

Researchers at the University of Michigan Health System Department of Dermatology have found scientific evidence that the appearance of sun-damaged skin may be improved by treatment with a topical product that increases the skin's sensitivity to light, followed by laser therapy.

St. Jude Medical gets U.S. and European approval of Angio-Seal Evolution Vascular Closure Device

St. Jude Medical, Inc. has announced U.S. Food and Drug Administration (FDA) and European CE Mark approval of the Angio-Seal Evolution Vascular Closure Device. The approval and global launch was announced at the Transcatheter Cardiovascular Therapeutics conference in Washington, D.C.

Sun-damaged skin does not improve with estrogen treatments

Treating the skin with estrogen can stimulate collagen production-which improves the appearance of the skin-in areas not typically exposed to the sun, according to new research from the University of Michigan Health System.

Researchers find genetic proof on how osteoarthritis destroys cartilage

A team of orthopaedic researchers has found definitive, genetic proof of how the most common form of arthritis destroys joint cartilage in nearly 21 million aging Americans, according to a study published online Sept. 2 in the Journal of Bone and Mineral Research. The findings serve as an important foundation for the design of new treatments for osteoarthritis (OA), researchers said.

Study reveals how blood flow force protects against atherosclerosis

Machines on cell surfaces, mechanical and lifeless as bed springs, protect blood vessels by responding to blood flow force, according to research published today in the Journal of Cell Biology. By sensing and reacting to force, such machines interfere with inflammatory pathways central to atherosclerosis, the cause of clogged arteries that lead to heart attack and stroke, the authors said. The next set of studies, already underway, seeks to "tweak" the process with the goal of designing a new class of therapies.

Genetic biomarker linked to subcutaneous growth hormone dose-response

The interindividual variability of response to subcutaneously applied protein-based drugs remains poorly understood. However, defining genetic markers that can be associated with biological effects of such drugs may improve the understanding of individual variability of response and even drug resistance.

Dissolvable ultra-fine, 3-dimensional scaffold offers a 'simple' solution to treating skin injuries

A revolutionary dissolvable scaffold for growing new areas of skin could provide a safer, more effective way of treating burns, diabetic ulcers and similar injuries.

Ultra-miniature bialy-shaped drug delivery particles

Ultra-miniature bialy-shaped particles - called nanobialys because they resemble tiny versions of the flat, onion-topped rolls popular in New York City - could soon be carrying medicinal compounds through patients' bloodstreams to tumors or atherosclerotic plaques.

Laser treatment the best fix for wrinkles

According to dermatologists in the U.S. laser treatment is a more effective way of removing wrinkles than some newer procedures.

An inflamed response

Paul Martin, Professor of Cell Biology in the University of Bristol Departments of Physiology and Pharmacology, and Biochemistry, talked to Cherry Lewis about the discovery made in his lab that speeds up wound healing and reduces the size of the wound scar. She was interested not only in the discovery itself, but also in the processes and years of research that led up to it.

Fluorescent-probe in worm creates real-time "view" of cellular stress

Scientists at the University at Buffalo have created a mutant worm that changes color when it moves. The color change is generated by an optical sensor called stFRET. The sensor is composed of a pair of fluorescent molecules connected by a molecular spring that is inserted into structural proteins in the worm's cells.

Saving teeth by using periodontal ligament regeneration

Teeth may fall out as a result of inflammation and subsequent destruction of the tissues supporting the teeth. Dutch researcher Agnes Berendsen has investigated a possible solution to this problem. At the Academic Centre for Dentistry Amsterdam (ACTA), she has studied the regeneration of the periodontal ligament by use of tissue engineering.

U of M sets new standard of care for recessive dystrophic epidermolysis bullosa

Physicians at the University of Minnesota and University of Minnesota Children's Hospital, Fairview have set the path to a cure for a young boy's fatal genetic skin disease, recessive dystrophic epidermolysis bullosa (RDEB), by using a cord blood and bone marrow transplant. Nate Liao, a 25-month-old from Clarksburg, N.J., underwent the experimental therapy in October 2007.

New type of wound dressing made of silica gel fibers

A new type of wound dressing made of silica gel fibers will soon help to heal difficult wounds caused by burns or diabetes. The dressing forms a supporting matrix for newly growing skin cells and is fully absorbed by the body during the healing process.

Why some treatments rescue aging skin

Fine wrinkles, deeper creases, saggy areas around the mouth and neck - the sights in the mirror that make baby boomers wince - are not inevitable. They result from a structural breakdown inside the skin that some existing treatments effectively counteract by stimulating the growth of new, youthful collagen, University of Michigan scientists say.
