Painful surgical adhesions may be preventable by taking the COX-2 inhibitor Celebrex

Adhesions – bands of scar tissue that bind together two internal body surfaces – develop in 55 percent to more than 90 percent of patients undergoing surgery, depending on the type of operation. They are part of normal healing, but when surfaces fuse together that shouldn't, serious pain and complications can result.

Association between fitness and survival suggests a link between impaired oxygen metabolism and disease

Research published in the current issue of Science magazine reinforces the belief that aerobic capacity is an important determinant in the continuum between health and disease.

Researchers discover way to overcome major hurdle in gene therapy for cancer

In a new study published in the Jan. 25 issue of the Proceedings of the National Academy of Sciences (PNAS), the researchers demonstrated that the technique works by incorporating it into a specially designed virus. The virus eradicated prostate cancer cells in the lab and in animals while leaving normal cells unscathed.

Instant tea may be a source of harmful levels of fluoride

The researchers found that some regular strength preparations contain as much as 6.5 parts per million (ppm) of fluoride, well over the 4 ppm maximum allowed in drinking water by the Environmental Protection Agency and 2.4 ppm permitted in bottled water and beverages by the Food and Drug Administration.

Supermarket bakery workers are at considerable risk of developing work related asthma

The researchers looked at 239 employees from 20 in-store bakeries for a supermarket chain. They collected data from questionnaires on a number of respiratory symptoms including chest tightness, breathing difficulties, chest wheezing or whistling, running or itchiness of the nose and eyes and sneezing. They also used skin prick tests to check for allergies associated with baking.

Theory on evolution of essential genes is overturned

A gene passed on by fathers that plays a vital role in helping fertilised eggs to develop into adults has helped scientists overturn the idea that essential genes have always been part of the genetic makeup of a species.

Research into foot-eye coordination

By measuring how people respond when a stepping stone suddenly shifts its position mid-step, researchers at the Institute of Neurology in London have shown that a powerful visual process controls the stepping foot – a process similar to that used for manual reaching, in which the hand is rapidly and automatically driven by visual information.

Evolutionarily ancient enzyme-repair system used to identify type of DNA damage responsible for the onset of skin-tumor development

In a finding that broadens our insight into the cause of certain kinds of UV-induced skin cancer, researchers at Erasmus University Medical Center (Rotterdam, The Netherlands) have employed an evolutionarily ancient enzyme-repair system to identify the principal type of DNA damage responsible for the onset of skin-tumor development.

Stem cells given in minimally invasive procedure improve heart function

Patients with severe congestive heart failure who had exhausted all other treatment options showed markedly improved heart function following a procedure in which their own stem cells were deployed directly into the heart by way of four tiny incisions in the chest, according to results of a trial presented today at the 41st Annual Meeting of the Society for Thoracic Surgery.

Local environment directly influences adult stem cell reservoirs

Using the common fruit fly, researchers at UT Southwestern Medical Center have discovered that an intricate set of signals released by stem cells' surroundings governs their maintenance.

Researchers have uncovered evidence of sexual reproduction in a single-celled organism long thought to reproduce asexually

The finding by John M. Logsdon, Jr., assistant professor in the UI College of Liberal Arts and Sciences Department of Biological Sciences and the Roy J. Carver Center for Comparative Genomics, and colleagues from the UI and Roanoke College (Virginia), provides the first clear evidence that meiosis arose very early in eukaryotic evolution, bringing science one step closer to understanding the mystery of sexual evolution.

Genetic defect leads to electrical instability and mechanical pump failure

In genetic mapping of a large family with several members affected by a type of heart failure called dilated cardiomyopathy (DCM), the Mayo Clinic team found a defect in a gene on chromosome 3 called SCN5A.

Research may provide the basis for development of a new, extensive immunotherapy for human tumors

Scientists have made significant progress towards understanding how the immune system can be more specifically and efficiently targeted against cancer cells. The research, published in the January issue of Immunity, may provide the basis for development of a new, extensive immunotherapy for human tumors.

Brain regions decide where we look

Scientists have found the brain regions that decide where we look, and where to direct our eyes when we’re faced with a difficult choice, such as looking someone straight in the eye or looking away.

High cholesterol, hypertension, diabetes and smoking may increase risk of dementia

High cholesterol, hypertension, diabetes and smoking have long been considered -- and aggressively treated -- as risk factors for cardiovascular disease.

Aastrom Biosciences responds to article regarding contaminated stem cell lines

Aastrom Biosciences responded today to the publication in the Sunday online edition of Nature Medicine of findings by California researchers that indicate that certain lines of human embryonic stem cells have been contaminated through the use of mice feeder cells.

Basic biochemical composition of heart valves in patients with congestive heart failure are markedly different than those with healthy hearts

Surprising new findings in the Journal of the American College of Cardiology show that the basic biochemical composition of heart valves in patients with congestive heart failure are markedly different than those with healthy hearts, a finding that may explain the mixed success of surgery to repair valve dysfunction in these patients.

Plant protein mimics hormone that mitigates diabetes and obesity

A common protein that protects plants from fungal infection mimics the activity of a hormone in mammals that is linked to weight loss and is believed to play a role in mitigating heart disease, obesity and diabetes, according to a team of researchers at Purdue University and several collaborating institutions.

Lack of the enzyme acetyl CoA carboxylase 2 turns fat cells into fat burners

Lack of the enzyme, acetyl CoA carboxylase 2 or ACC2, appears to turn the adipose or fat cells of mice into fat burners, explaining in part why the animals can eat more and weigh less than their normal counterparts, said Baylor College of Medicine researchers.

School influenza vaccinations best strategy for slowing flu transmission

The best strategy for minimizing future influenza morbidity and mortality would be to concentrate vaccinations in school children and high-risk groups, according to a new research commentary by scientists at Emory University.
