Memories Lost Due to Neuro-degenerative Diseases may Be Restored

...ment turned out to have higher levels of "synaptic marker proteins", an indication that the "wiring" between neurons in the brain had been re-established. It may be possible to restore lost memories with drugs that trigger the natural "rewiring" of brain cells, the study said. The findings could lead t...

Intake of Cherries Could Cut the Risk of Metabolic Syndrome and Heart Disease

...the cherry-fed groups had lower levels of a plasma marker of oxidative damage and increased blood antioxidant capacity – not surprising since cherries are one of the richest sources of antioxidants. Additionally, the cherry-enriched diets reduced "fatty liver" or the accumulation of triglycerides and chol...

New blood test to detect prostate cancer

...,' he adds. EPCA-2 is the second prostate-cancer marker identified by Getzenberg and his team that has outperformed PSA. Last year, they discovered an unrelated, tissue-based test, EPCA-1, that also proved effective at identifying prostate cancer. The only commonality between these markers is that they we...

Alcohol Abuse During College Days Leads to Heart Disease in Later Life

...higher levels of C-reactive protein (CRP), a blood marker for inflammation that can increase the risk for heart disease. Increased CRP placed heavy drinkers at moderate risk for cardiovascular disease in early adulthood. Moderate drinkers had the lowest CRP levels. "These students may be setting themselv...

Physicists Unite To Develop Anthrax Detection Method

...and his colleagues used the dipicolinic acid (DPA) marker molecule to identify anthrax spores. “DPA, in the form of its salt, calcium DPA, accounts for 10 to 17 percent of the bacterial spore dry weight,” he notes. “In our research, we worked with sodium DPA, which is similar to the calcium salt, but easi...

Study Challenges Conventional Treatment of Traumatic Brain Injury

...dard intravenous solution. The isotope served as a marker they could follow to see if the lactate molecule had produced carbon dioxide, the natural byproduct of lactate after use by the brain as fuel. “Our preliminary tracer-based studies demonstrated the novel and unexpected finding of both lactate uptak...

Obesity Does Not Auger Well for Prostate Cancer Patients

... prostate-specific antigen, or PSA, a common blood marker for prostate cancer, and because their larger-sized prostates make it more likely for a biopsy to miss the cancer," he said. "These findings further suggest that we could be missing even more high-grade disease among obese men." Gaining a better ...

Biopsy may Underestimate Prostate Cancer in Obese and Overweight Men

... prostate-specific antigen, or PSA, a common blood marker for prostate cancer, and because their larger-sized prostates make it more likely for a biopsy to miss the cancer," he said. "These findings further suggest that we could be missing even more high-grade disease among obese men." Gaining a better un...

Sedentary Lives Equal Shorter ‘sweeter’ Livs

...ditive effect on risk, in that TV viewing may be a marker for a broader pattern of sedentary lifestyle that includes a variety of other forms of sitting time," he suggested. Dr. Richard Galloway, an endocrinologist at Hattiesburg Clinic, Mississippi agrees. He says that 30 minutes of exercise a day for fi...

Antioxidant Molecule Could Help Minimize Stroke-Linked Brain Damage

...ing sign: high brain levels of an oxidative stress marker called glutathione, which is usually depleted in areas affected by stroke/reperfusion. "If you have a stroke, you lose glutathione very quickly," Dr. Cho says. "That happened in the untreated mice, but SS31 seemed to keep glutathione levels relati...

NCPAP Decreases Cerebrovascular Risk in OSA Patients

...tive airway pressure (nCPAP) on serum inflammatory marker levels in 24 male patients who had moderate to severe OSA. According to the authors, the occurrence of stroke in patients with OSA is likely preceded by subclinical cerebrovascular disease, or silent brain infarction, which is detectable with brain...

Calcium in Arterial Plaque is a Good Indicator for Risk of Stroke

...f controversy about whether calcium in plaque is a marker of stability or instability,” Dr. Kramer explains. “When plaque in the coronary and carotid arteries is unstable, it is thought to lead to heart attack and stroke, respectively.” Study findings show that patients with plaque that is more than 45 pe...

‘Emotional’ Genetic Marker for Heart Diseases in Women Identifid

Caloric Restriction in Non-obese People Extends Life Span

...erventions also reduced the amount of DNA damage—a marker of oxidative stress—in the participants' muscles. The researchers also examined gene expression in the study participants. In yeast, worms, and flies the activation of the Sir2 gene increases life span and regulates cellular metabolism. An importan...

Hostile Behavior in Women may Be Gene Based

...These findings may aid in establishing a potential marker for certain conditions associated with aggression ...and heart diseases," said Dr. Halder. "The genetic marker we found for hostility also may be useful for predicting a person's predisposition to such diseases....

Severe PTSD Damages Children's Brains: Study

...mptoms and higher bedtime cortisol levels (another marker of stress) at the start of the study were more likely to have reductions in their hippocampal volumes at the end of the study than their less-affected, but still traumatized peers. It is significant that the change in the hippocampal volume corresp...

Treating Male Infertility With Stem Cells

...examined. Both germ and supporting cells expressed marker proteins known to be found only on the differentiated cells, not on stem cells. These data demonstrate that bone marrow stem cells have the potential to differentiate into cells of the testes involved in sperm production, both germ cells and suppo...

Green Tea and COX-2 Inhibitors Combine to Slow Growth of Prostate Cancer

...uced by the cells of the prostate and is used as a marker for detection and progression of prostate cancer. These results, combined with a marked decrease in the presence of cancer-promoting proteins, offered clear indications that green tea and celecoxib, combined, could be useful in slowing prostate cance...

Diesel Exposure Model Reduces Allergy Risk Assessment Errors

...xposed to the highest levels of elemental carbon—a marker of diesel exposure—were more than twice as likely to wheeze compared with the infants exposed to lower levels, which was reported in the February 2007 issue of Environmental Health Perspectives. Research has shown that diesel exhaust particles (DEP...

Statin Therapy Cuts Bad Cholesterol Unprecedented 70 Percent

...6 percent reduction in C-reactive protein (CRP), a marker for inflammation, in patients treated with 40 mg of rosuvastatin and 10 mg ezetimibe. “A seventy percent drop is the largest reduction in bad cholesterol ever seen in a statin clinical trial. Cardiologists have long recognized the challenge in help...
