PREOPERATIVE NUTRITIONAL SUPPLEMENT IMPROVES OUTCOME FOR HIGH-RISK PATIENTS UNDERGOING HEART SURGERY (p 696)
An immune-enhancing nutritional supplement conventionally used in critical care and cancer surgery could be beneficial for elderly and other high-risk patients requiring cardiac surgery, conclude authors of a study in this week’s issue of THE LANCET. Elderly patients and those with poor ventricular function have increased illness and death... view more... (2001-08-29)
Same-day coronary angiography and surgery safe for many patients
Mayo Clinic researchers discovered it is safe -- and much more convenient and less costly -- for many patients to undergo coronary angiography and elective valve surgery on the same day, it is reported in the current issue of Mayo Clinic Proceedings. view more (2007-05-24)
University of Leicester engineers seek new way to control engine friction
An innovative engine testing rig is being developed in the Engineering Department at the University of Leicester. The rig will be used to study friction in engines, which is one of the main sources of inefficiency and energy loss. Frictional losses occur in all automotive engines, primarily in the piston system, the valve-train and the engine... view more... (2003-11-06)
Titanium human “spare parts”
Heart valves bred from a patient’s own cells would be a big progress. Meanwhile, surgeons have to make do with other methods and materials: tissue grafts, modified heart valves from human or animal donors. Valves made from artificial materials have the advantage of lasting longer. But they have the unfortunate drawback to intensify the... view more... (2002-09-09)
UCLA chemists create nano valve
UCLA chemists have created the first nano valve that can be opened and closed at will to trap and release molecules. The discovery, federally funded by the National Science Foundation, will be published July 19 in the Proceedings of the National Academy of Sciences. view more (2005-07-18)
Endobronchial valve significantly improves emphysema
Emphysema patients whose lungs are implanted with a pencil eraser-sized, one-way endobronchial valve experience significantly improved measures of lung function and report better quality of life, University of Pittsburgh School of Medicine researcher Frank C. Sciurba, M.D., reported today at CHEST 2007, the annual meeting of the American College... view more... (2007-10-23)
UC Davis researchers define characteristics, treatment options for XXYY syndrome
Researchers at the UC Davis M.I.N.D. Institute and The Children's Hospital in Denver have conducted the largest study to date describing the medical and psychological characteristics of a rare genetic disorder in which males have two "X" and two "Y" chromosomes, rather than the normal one of each. view more (2008-08-25)
Pelvic disorders affect large number of women, UT Southwestern researchers find
Nearly one-quarter of all women suffer from pelvic-floor disorders, such as incontinence, at some point in their lives, a national study, including researchers from UT Southwestern Medical Center, has found. view more (2008-09-18)
Scientists discover how to isolate stem cells in womb tissue
Scientists in Australia have found a way of identifying probable stem cells in the lining of women's wombs. The finding opens up the possibility of using the stem cells for tissue engineering applications such as building up natural tissue to repair prolapsed pelvic floors. Pelvic floor prolapse is a common condition, affecting over 50% of women... view more... (2007-09-13)
Surgeons at Boston Medical Center offering new procedure for acid reflux/GERD
Boston Medical Center (BMC) surgeons are now offering patients an incisionless alternative to laparoscopic and traditional surgery for treatment of acid reflux or GERD. view more (2009-10-27)
NYC-area 1st: Morgan Stanley Children's Hospital performs transcatheter pulmonary valve replacement
A breakthrough new procedure may improve quality of life for children and adults with a common type of congenital heart defect that interferes with the body's ability to oxygenate blood through the lungs. view more (2007-08-23)
Successful treatment for acute heart failure remains elusive
In recent years, cardiologists have begun to view acute heart failure syndrome (AHFS) as a distinct condition, not merely a part of the chronic heart failure continuum. view more (2005-12-21)
A step toward tissue-engineered heart structures for children
Infants and children receiving artificial heart-valve replacements face several repeat operations as they grow, since the replacements become too small and must be traded for bigger ones. Researchers at Children's Hospital Boston have now developed a solution: living, growing valves created in the lab from a patient's own cells. view more (2007-09-13)
Infective endocarditis: An old but changing disease
Infective endocarditis (IE) is a severe form of valve disease characterized by infection located in the valves of the heart. view more (2009-08-31)
Natural polyester makes new sutures stronger, safer
With the help of a new type of suture based on MIT research, patients who get stitches may never need to have them removed. view more (2007-03-23)
Building the lymphatic drainage system
Our bodies' tissues need continuous irrigation and drainage. Blood vessels feeding the tissues bring in the fluids, and drainage occurs via the lymphatic system. While much is known about how blood vessels are built, the same was not true for lymph vessels. view more (2009-04-27)
Large Area High Definition Television (HDTV) prototype based on Liquid Crystal on Silicon (LCoS) Light Valves.
The microsystems group TFCG/IMEC at the University of Gent has developed a large area High Definition Television (HDTV) prototype based on Liquid Crystal on Silicon (LCoS) light valves. This work is carried out in collaboration with the Taiwanese company TMDC. The LCoS HDTV is most suited for multimedia and DVD home-theater applications. The R&D... view more... (2003-04-30)
Deep magma matters in volcanic eruption cycle
Although the Soufriere Hills volcano on Montserrat exhibits cycles of eruption and quiet, an international team of researchers found that magma is continuously supplied from deep in the crust but that a valve acts below a shallower magma chamber, releasing lava to the surface periodically. view more (2008-10-10)
Infectious heart disease death rates rising again say scientists
Infectious heart disease is still a major killer in spite of improvements in health care, but the way the disease develops has changed so much since its discovery that nineteenth century doctors would not recognize it. view more (2008-09-11)
Link between obesity and enlarged heart discovered by University of Arizona researchers
New research from The University of Arizona Sarver Heart Center helps explain why excessive body weight increases the risk for heart disease. view more (2007-06-20)
