Effects of chronic stress can be traced to your genes Posted: 05 Nov 2013 02:13 PM PST New research suggests that if you're working for a really bad boss over a long period of time, that experience may play out at the level of gene expression in your immune system.

Interactive computer program helps patients talk with physician about depression Posted: 05 Nov 2013 01:22 PM PST Patients who used an interactive computer program about depression while waiting to see their primary-care doctor were nearly twice as likely to ask about the condition and significantly more likely to receive a recommendation for antidepressant drugs or a mental-health referral from their physician, according to a new study.

Breakthrough could lead to new treatment for heart attack Posted: 05 Nov 2013 01:05 PM PST The stop and start of blood flow to the heart during and after a heart attack causes severe damage to heart cells, reducing their capacity to function and potentially causing their death. But a recent study suggests that it is possible to limit the extent of that damage using a drug. The findings have significant potential for translation into heart attack patients in a clinical setting.

Gene is linked to deadly runaway fungal infection Posted: 05 Nov 2013 12:32 PM PST For most people, a fungal infection like athlete's foot means a simple trip to the drugstore and a reminder to bring shower shoes to the gym. But in very rare cases, fungal infections can spread below the skin's surface and onto the lymph nodes, bones, digestive tract or even the brain. Researchers have now discovered a genetic deficiency that allows the fungus to spread in this way, which explains why treatments sometimes do not work.

Intestinal bacteria linked to rheumatoid arthritis Posted: 05 Nov 2013 10:20 AM PST Researchers have linked a species of intestinal bacteria known as Prevotella copri to the onset of rheumatoid arthritis, the first demonstration in humans that the chronic inflammatory joint disease may be mediated in part by specific intestinal bacteria. The new findings add to the growing evidence that the trillions of microbes in our body play an important role in regulating our health.

Scientists use light to uncover the cause of sickle cell disease Posted: 05 Nov 2013 09:14 AM PST In sickle cell disease, hemoglobin -- the oxygen-carrying component of blood -- forms fibers that stiffen red blood cells and cause life-threatening symptoms. Using light-scattering techniques to study the detailed thermodynamics of this process, researchers have determined the strength of the forces that hold these fibers intact. The information could be used to design therapies that interfere with the sickling process.

New cancer targeting technique to improve cancer drugs Posted: 05 Nov 2013 08:25 AM PST Cancer drugs work because they're toxic, but that's also why they afflict healthy cells, producing side effects that can compromise their efficacy. Researchers may have found a way to get the drugs to selectively target only the cancer cells.

Holograms offer hope in fight against malaria Posted: 05 Nov 2013 07:36 AM PST Scientists have developed a 3D filming technique that could help inform research to stem the spread of malaria.

Drug combination therapy causes cancer cells to 'eat themselves' Posted: 05 Nov 2013 07:36 AM PST Results from a recent preclinical study have shown that a new drug combination therapy effectively killed colon, liver, lung, kidney, breast and brain cancer cells while having little effect on noncancerous cells. The results lay the foundation for researchers to plan a future phase 1 clinical trial to test the safety of the therapy in a small group of patients.

Play promotes emotional healing in children battling serious illnesses Posted: 05 Nov 2013 07:36 AM PST Playing out medical experiences can help chronically ill children, as well as their siblings, express fears and foster hope for recovery.

Gambling addicts present brain function abnormalities that affect their decision-making capacity Posted: 05 Nov 2013 06:31 AM PST Researchers have analyzed similarities and differences in psychological profile and brain function when comparing cocaine addicts and gambling addicts. The study reveals that gambling addicts present brain function abnormalities affecting their decision-making capacity.

Higher rates of diabetes, hypertension, heart disease, stroke in 'food desert' Posted: 05 Nov 2013 05:15 AM PST A study has examined the health impact of developing a grocery store in a low-income urban neighborhood on the east side of Indianapolis. Researchers from Indiana University-Purdue University Indianapolis and the Marion County Public Health Department found that residents of the community have much higher rates of diabetes, hypertension, heart disease and stroke than in other areas of Marion County.

Microbes in the gut help determine risk of tumors Posted: 05 Nov 2013 05:15 AM PST Transferring the gut microbes from a mouse with colon tumors to germ-free mice makes those mice prone to getting tumors as well, according to the results of a study. The work has implications for human health because it indicates the risk of colorectal cancer may well have a microbial component.

Bad boys: Research predicts whether boys will grow out of it or not Posted: 05 Nov 2013 05:15 AM PST Using the hi-tech tools of a new field called neurogenetics and a few simple questions for parents, a researcher is beginning to understand which boys are simply being boys and which may be headed for trouble.

Visual representations improved by reducing noise in the brain Posted: 05 Nov 2013 05:13 AM PST Neuroscientists have revealed how the activity of neurons in an important area of the rhesus macaque's brain becomes less variable when they represent important visual information during an eye movement task. This reduction in variability can improve the perceptual strength of attended or relevant aspects in a visual scene, and is enhanced when the animals are more motivated to perform the task.

Hypersensitivity to pain produced by early life stress worsened by later stress exposure Posted: 05 Nov 2013 05:13 AM PST Childhood neglect and abuse, whether physical or psychological, confers a lifetime vulnerability to stress, anxiety, and mood problems. Such early-life stress is also suspected to contribute to the development of chronic pain in adulthood. In fact, there is growing concern that chronic pain syndromes may be a complication of posttraumatic stress disorder (PTSD). However, this link is particularly challenging to study because many stressful events that produce PTSD also produce physical trauma.

New ligament discovered‬ in the human knee Posted: 05 Nov 2013 05:13 AM PST Two knee surgeons have discovered a previously unknown ligament in the human knee. This ligament appears to play an important role in patients with anterior cruciate ligament (ACL) tears.

Endometriosis risk linked to two pesticides Posted: 05 Nov 2013 05:11 AM PST A study has found that two organochlorine pesticides are associated with an increased risk of endometriosis, a condition that affects up to 10 percent of reproductive-age women.

Non-celiac wheat sensitivity: Is it an allergy? Posted: 05 Nov 2013 05:11 AM PST Patients with non-celiac wheat sensitivity and other food sensitivities showed clinical, laboratory and histological characteristics suggesting they may be suffering from a non-IgE-mediated food allergy, according to new research.
