A new study shows that long-term alcoholism affects sleep even after long periods of abstinence, and the pattern of this effect is similar in both men and women.
Scientists now have proof of a sudden, remarkably warm period in Antarctica that occurred about 15.7 million years ago and lasted for a few thousand years.
When used "off-label," the antidepressant amitriptyline works just as well as placebo in treating pain-predominant gastrointestinal disorders in children.
The levels of the components in breast milk change every 24 hours in response to the needs of the baby. A new study shows, for example, how this milk could help newborn babies to sleep.
Worldwide, thousands of workers die every year from mining accidents, and instantaneous coal outbursts in underground mines are among the major killers. But although scientists have been investigating coal outbursts for more than 150 years, the precise mechanism is still...
Scientists have found an effective combination of positron emission tomography/computed tomography tests to diagnose lung cancer in a "fast-tracked" outpatient setting. This novel approach to the diagnosis of lung cancer demonstrated a high level of sensitivity (97 percent) and accuracy (82 percent). The fast track model tests patients for lung cancer over the course of one day and could expedite...
Children who eat sweets and chocolates every day are more likely to be violent as adults, according to a new study. Researchers found a higher percentage of adults who were violent at age 34 had eaten sweets every day, compared to those who were non-violent. This link persisted after controlling for other...
A new study shows that elderly women sleep better than elderly men even though women consistently report that their sleep is shorter and poorer.
A new study finds intoxicated trauma patients were more likely to survive their injuries than trauma patients who were sober.
A recent study determined that variations of specific genetic markers identified in previous research, or SNPs, may indicate a greater lung cancer risk in African Americans than in whites. The genes CHRNA3 and CHRNA5 may contribute to lung cancer risk due directly or through their association with nicotine dependence. Although their presence is less frequent in African-Americans, the risk for lung...
A promising new molecular imaging technique may provide physicians and patients with a noninvasive way to learn more information about a type of cancer of the uterus lining called "endometrial carcinoma" -- one of the most common malignant female tumors.
Initial chemotherapy alone after surgery is just as successful as initial radiation therapy for patients from whom a very malignant brain tumor (anaplastic glioma) was removed, a new study has found. With this treatment, the patients survive on average more than 30 months without a recurrence. Patients in primary therapy benefit to the same extent from chemotherapy alone as from radiation...
Here's another reason why you should take your vitamins. A new research report suggests that retinoic acid, the oxidized form of vitamin A, could be a beneficial treatment for people suffering from ulcerative colitis and other irritable bowel diseases. Specifically they found that retinoic acid helps suppress out-of-control inflammation, which is a hallmark of active ulcerative...
According to a new study, early outcomes of platelet-rich plasma treatment appear promising; however, larger clinical studies are still needed to determine the benefits of its use.
Good news for procrastinating students: a nasal spray developed by scientists promises to give late night cram sessions a major boost, if a good night's sleep follows. Scientists show that a molecule from the body's immune system (interleukin-6) when administered through the nose helps the brain retain emotional and procedural memories during REM...
Mothers who smoke during pregnancy put their children at a higher risk of psychotic behavior, according to a new study. Researchers studied more than 6,000 children aged for psychotic symptoms such as hallucinations and delusions. They found the risk of psychotic symptoms was highest in those children whose mothers smoked most heavily in...
Researchers have provided an analysis of the consequences for wildlife of the expanding production of bioenergy. The authors of new study identify harvesting of diverse prairie, which is dominated by perennial plants, as a strategy for production of bioenergy feedstocks that could minimize adverse...
A new study has found that ulcerative colitis patients had a 41 percent reduction in colectomy after a year when treated with infliximab.
A disconnect between the way wrist-fracture patients and those with a spine or hip fracture are managed and evaluated has been reviewed. The study, conducted in 2007 among 97 percent of the women in Korea, reviewed the incidence of fractures around the hip, spine, and wrist in female patients age 50 and older and the prescription frequencies of bone density scans for osteoporosis, along with the...
Fewer than half of men and women in Ontario who may be suffering from depression see a doctor to treat their potentially debilitating condition, according to a new women's health study. What's more, many hospitalized for severe depression fail to see a doctor for follow-up care within 30 days of being discharged, and many head to hospital emergency departments for...
Researchers in Louisiana are conducting innovative research on geopolymer concrete and providing ways to use a waste byproduct from coal fired power plants and help curb carbon dioxide emissions.
Tiny organisms known as archaea play a central role in the planet's nitrogen cycle, according to new research. Experiments show that archaea appear play a key ecological role in both upper and deep ocean ecosystems. This could affect calculations made by global climate...
The American chestnut was a dominant species in eastern US's forests before a blight wiped it out in the early 1900s. Today it's being returned to the landscape thanks in part to work by Tennessee forestry experts.
Soybeans contain high levels of several health-beneficial compounds including tocopherols, which have antioxidant properties. These molecules can be used in the development of functional foods, which have specific health-beneficial properties and can be used in the treatment or prevention of...
