Chronic self-doubters likely to face wide range of problems

People who chronically doubt their judgments lead psychologically impoverished lives in a variety of ways, a new study suggests. Such individuals often feel anxious, are prone to sadness and mood swings, and are likely to procrastinate and avoid thinking about difficult problems. "People who are dubious about their judgment are highly vulnerable," said Herbert Mirels, primary author of the study and professor of psychology at Ohio State University. "They see every important decision they make as a trial in which they are likely to find themselves deficient or to be found deficient by others."

Device acts as heart’s security system

Heart failure patients at the Ohio State University Heart Center may be seeing less of their doctors. And the doctors couldn't be happier. A group of patients is testing a first-of-its-kind implantable monitor that transmits critical data from their heart over the telephone, eliminating travel to the doctor's office for the same type of monitoring. Proven successful, the experimental device could herald a major breakthrough for the growing number of people diagnosed with heart failure. Those living with heart failure could enjoy an improved lifestyle with less dependency on frequent doctor visits, and for cardiac researchers it might be the most advanced bellwether device yet for detecting heart problems at their earliest stages.

Topical oxygen helps hard-to-heel wounds heal faster and better

A new study suggests that brief exposures to pure oxygen not only help chronic and other hard-to-heal wounds heal completely, such exposures also help wounds heal faster. Ohio State University surgical scientists used topical oxygen therapy to treat 30 patients with a total of 56 wounds. The therapy required placing a bag containing pure oxygen over the wound for 90 minutes a day. More than two-thirds of the difficult wounds healed with the oxygen treatment alone.

Fat that may benefit diabetics reduces weight, blood sugar

Supplementing the diet with a certain fatty acid may lead to better weight control and disease management in diabetics, a new study suggests. Diabetics who added an essential fatty acid called conjugated linoleic acid (CLA) to their diets had lower body mass as well as lower blood sugar levels by the end of the eight-week study. Hyperglycemia, or high blood sugar, is a hallmark of diabetes. Researchers also found that higher levels of this fatty acid in the bloodstream meant lower levels of leptin, a hormone thought to regulate fat levels. Scientists think that high leptin levels may play a role in obesity, one of the biggest risk factors for adult-onset diabetes.

Too much oxygen on the cell biology bench? New study suggests...

Research conducted at Ohio State University suggests that cell biologists may be exposing the cell cultures they study to too much oxygen. This finding could have broad implications for cellular biology research, which receives billions of dollars of funding nationally, said Ohio State scientist Chandan Sen. He is the lead author of a study which suggests that cells act differently depending on how much oxygen they are exposed to, especially when it is too much.

Black holes form first, galaxies follow

A new study has uncovered more evidence that black holes form before the galaxies that contain them. The finding could help resolve a long-standing debate, says the study's lead scientist. Marianne Vestergaard, a postdoctoral fellow in astronomy at Ohio State, came to this conclusion when she studied a collection of very energetic, active galaxies known as quasars as they appeared some 12 billion years ago, when the universe was only one billion years old. While the quasars were obviously young -- they contained large stellar nurseries in which new stars were forming -- each also contained a very massive, fully formed black hole.

Gelatin particles show promise in gene therapy for kidney disease

Researchers have successfully tested micro-sized gelatin particles that may one day deliver therapeutic genes to treat a type of kidney disease. The biodegradable gelatin particles are so small that at least 10 would fit on the period at the end of this sentence. Researchers believe such particles could carry therapeutic genes to the glomerulus, a tiny cluster of capillaries within the kidney that filters toxins from the blood. This filtration system becomes blocked when patients develop glomerular disease.

Grape seed extract may help wound healing

Grape-seed extract may help skin wounds heal faster and with less scarring, a new study suggests. The extract seemed to aid wound healing in two ways: It helped the body make more of a compound used to regenerate damaged blood vessels, and it also increased the amount of free radicals in the wound site. Free radicals help clear potentially pathogenic bacteria from a wound.

Listening to music while working out helps people with severe lung...

Researchers believe that listening to music helped people with severe respiratory disease increase their fitness levels, based on the results of a new study. Subjects with serious lung disease who listened to music while walking covered an average of 19 total miles over the course of an eight-week exercise intervention study. In comparison, the group that didn't listen to music only walked an average of 15 total miles ? 21 percent less - by the end of the study. That four-mile difference is significant, said Gerene Bauldoff, a study co-author and an assistant professor of nursing at Ohio State University. It suggests that participants in the music group may have felt less hindered by shortness of breath, the primary physical symptom of serious lung disease.

Telescope mirror to get shiny finish in major test run

In an airplane hangar in Columbus, OH, some 80 tons of steel, electronics, and cryogenic equipment are about to come together -- all to deposit one ounce of aluminum as a near-perfect, whisper-thin coating on a giant telescope mirror. The successful operation of the coating system will represent a milestone in the construction of the Large Binocular Telescope (LBT), and a critical phase in Ohio State University 's participation in the LBT project.
