A report in the May issue of the journal Developmental Dynamics reveals that biologists from the Tufts University have, for the first time, discovered a "self-correcting" mechanism by which developing organisms recognize and repair head and facial abnormalities. This is the first time that this kind of flexible, corrective process has been rigorously analyzed through mathematical modeling. The study demonstrates that developing organisms are not genetically "hard-wired", but that the process is, instead, more flexible and robust. By using a tadpole model with a set of pre-determined cell movements that result in normal facial features, they demonstrated that cell groups can measure their shape and position in relationship to other organs, as well as performing the required movements and remodeling functions in order to compensate for important abnormalities in patterns.
The Treasury's plans to introduce Royal Mint nickel-plated coins, in order to save costs, are examined in a letter published in BMJ(British Medical Journal). The letter, by skin experts from St. John's Institute of Dermatology and the Royal Hallamshire Hospital, states that there has been no evaluation of the new coinage. According to the experts, HM Treasury officials and the Royal Mint have given no consideration to the financial implications to the NHS, the potential health expenses causes by skin disease, or other costs to the taxpayer. Furthermore, the Royal Mint has verified that they have not conducted any studies or evaluations oh how the coins may affect individuals allergic to nickle and that they have "no information on nickel-release from the new coins." According to the Treasury's Swedish counterparts, Swedish Riksbank, nickel-plated coins "pose unacceptable risks to health.
The Olympics are all about the "thrill of victory and the agony of defeat." But for many Summer Games athletes, there's also the agony of skin irritations and conditions that can make the journey to the medal stand more difficult. Skin problems rank among athletes' most common complaints, but there's little information available regarding dermatoses among Olympic athletes, according to findings from Wake Forest Baptist Medical Center. And who would know better than an Olympic medalist turned physician? Jacqueline F. De Luca, M.D., a resident in the dermatology department at Wake Forest Baptist, was a member of the U.S. women's water polo team that won a bronze medal at the 2004 Summer Olympics in Athens, Greece. During a research fellowship at Wake Forest Baptist under the guidance of dermatologist Gil Yosipovitch, M.
A mystery skin infection, which has killed 19 people and affected hundreds, has left Vietnamese health authorities baffled. Vietnam is now asking for help from abroad to find out what exactly this disease is, what the cause is, and how to effectively treat it and stem its spread. Over 170 cases have been reported in Quang Ngai province, in the center of the country. Patients start off with a high fever, loss of appetite, and a rash on the soles of their feet and palms of their hands. They can suffer liver problems, and eventually multiple organ failure. Local media inform that approximately 10% of infected people suffer from serious liver disorder. Despite what it describes as extensive investigations, the country's Health Ministry does not know what the cause of the infection is.
Fibronectin plays a major role in wound healing and embryonic development. The protein, which is located in the extracellular matrix of cells, has also been linked to pathological conditions including cancer and fibrosis. During physiological processes, fibronectin fibers are believed to experience mechanical forces that strain the fibers and cause dramatic structural modifications that change their biological activity. While understanding the role of fibronectin strain events in development and disease progression is becoming increasingly important, detecting and interrogating these events is difficult. In a new study, researchers identified molecular probes capable of selectively attaching to fibronectin fibers under different strain states, enabling the detection and examination of fibronectin strain events in both culture and living tissues.
