MicroRNAs Grease The Cell's Circadian Clockwork
Most of our cells possess an internal clock, a group of genes displaying a cyclic expression pattern that reaches a peak once a day. A large number of circadian genes are expressed by organs such as the liver, whose activity needs to be precisely regulated over the course of the day. A team of researchers of the National Centre of Competence in Research Frontiers in Genetics, based at the University of Geneva, Switzerland, reveals that an important regulator of this molecular oscillator is a specific microRNA. The latter belongs to a class of small RNA molecules that regulate the production of proteins in our cells. Thus far, little was known about their function within the circadian clockwork. The study by Ueli Schibler"s team, published in the 1st June edition of Genes & Development, fills in this important gap.

The Harley Medical Group Reports On Nipple Surgery Trend

Another option, nipple elevation, involves the nipple being raised above its existing level to enhance its appearance and make the breast look more pert.

Launch Of Lung Health Check On WebMD Announced By COPD Foundation

The COPD Foundation announces launch of the Lung Health Check, developed in an educational collaboration with WebMD. Development of the Lung Health Check was made possible by funding from the COPD Foundation. The Lung Health Check is an educational platform at http://www.webmd.com/lung-disease-health-check that both teaches the key symptoms and risks of developing lung disease, and suggests appropriate steps to take to prevent or manage disease. This solution offers a quick check on the effects that a breathing problem is having on a person"s life, and offers suggestions both for those already diagnosed with a lung problem and those with respiratory symptoms as yet undiagnosed. The Lung Health Check will not give out medical advice, but is intended to serve as an educational re and tool. "The COPD Foundation is extremely excited about this collaboration with WebMD and to be able to provide a re on lung health," said John W. Walsh, President of the COPD Foundation. Walsh said the new platform will help "inform, educate, empower and engage individuals to learn more about their lung health," and enable more effective interaction with healthcare providers. "Those of us already diagnosed with lung conditions like COPD understand the importance of early and complete diagnosis and the value of "learn more breathe better"," said Walsh. He said the Lung Health Check will be "a re to millions of people searching for answers" to their shortness of breath. "Millions have been diagnosed with lung problems and millions more have symptoms suggesting a possible lung problem, shortness of breath or cough or phlegm production, but remain undiagnosed," said Byron Thomashow, MD, Chairman of the COPD Foundation. "Most lung problems are treatable but can only be treated if properly diagnosed," Thomashow said. "The Lung Health Check allows people with respiratory complaints to get a better idea of their lung health and then share the results with their healthcare provider. For some, the Lung Health Check may be a place to start. For others it may be a place to gauge one"s progress." After completing the Lung Health Check, users receive three customized reports that focus on various aspects of health and offer suggestions such as how to ask for help, reduce stress, get better sleep and stay active. This online solution is designed to assist both health care providers - physicians, nurses, respiratory therapists - and people concerned about their own lung health or that of their family members. Patients can print the reports and bring them to a physician, which may aid in diagnosis. The Lung Health Check also provides access to a wealth of information and res. It teaches people to take an active role in managing their disease, including how to follow a medication regimen, and explains the kinds of testing needed for proper diagnosis (such as spirometry for COPD). The Lung Health Check is just one of several programs the COPD Foundation has created to spread awareness of COPD for the year 2010, which the World Health Organization has designated "The Year of the Lung." The Lung Health Check is an educational collaboration between WebMD and the COPD Foundation. The Lung Health Check is not a program of the American Thoracic Society. About COPD: Chronic obstructive pulmonary disease (COPD) is the 4th leading cause of death in the U.S. and is expected to become the third by 2020. COPD is the only one of the leading causes of death which is still increasing in mortality. The National Heart, Lung, and Blood Institute estimates that 24 million Americans have COPD, but only half of them are diagnosed; the other 12 million don"t know they have COPD and are not receiving appropriate treatment. The cost of COPD health care for American taxpayers in 2007 is estimated at $42.6 billion. Ifdy Perez COPD Foundation
