Can your brain control how it loses control? Posted: 14 Aug 2015 11:57 AM PDT A new study may have unlocked understanding of a mysterious part of the brain -- with implications for neurodegenerative conditions such as Alzheimer's. The results open up new areas of research in the pursuit of neuroprotective therapies

Study shows how climate change threatens health Posted: 14 Aug 2015 11:57 AM PDT A new study is focused on the public health implications of climate change on the US Gulf Coast. The study has implications for other coastal regions, including the Northeast and West Coast, author say.

Novel diagnostic tool for ethnically diverse non-small-cell lung cancer patients Posted: 14 Aug 2015 11:57 AM PDT Early-stage Non-small-cell Lung Cancer is asymptomatic and difficult to detect since no blood test for NSCLC is currently available. In a new study, researchers identified a panel of five serum microRNAs as the potential biomarker for NSCLC diagnosis.

Revealed: Helicobacter pylori's secret weapon Posted: 14 Aug 2015 11:56 AM PDT Is the game up for Helicobactor pylori? Researchers have identified the molecular mechanism that the bacterium's best-known adhesion protein uses to attach to stomach sugars and evade the body's attempts to 'flush' it away.

'Fishing expedition' nets nearly tenfold increase in number of sequenced virus genomes Posted: 14 Aug 2015 08:37 AM PDT Using a specially designed computational tool as a lure, scientists have netted the genomic sequences of almost 12,500 previously uncharacterized viruses from public databases.

Young minds think alike; older people are more distractible Posted: 14 Aug 2015 07:15 AM PDT Age is believed to change the way our brains respond and how its networks interact, but studies looking at these changes tend to use very artificial experiments, with basic stimuli. To try to understand how we respond to complex, life-like stimuli, researchers showed 218 subjects aged 18-88 an edited version of an episode from a Hitchcock TV series while using functional magnetic resonance imaging (fMRI) to measure their brain activity.

Higher intelligence score means better physical performance Posted: 14 Aug 2015 07:15 AM PDT New research reveals a distinct association between male intelligence in early adulthood and their subsequent midlife physical performance. The higher intelligence score, the better physical performance, the study reveals.

'Brainy' mice raise hope of better treatments for cognitive disorders Posted: 14 Aug 2015 07:15 AM PDT Researchers have created unusually intelligent mice by altering a single gene and as a result the mice were also less likely to feel anxiety or recall fear.

Tdap booster vaccine rates triple at family care clinics using automated reminders Posted: 14 Aug 2015 06:13 AM PDT Electronic reminders at clinics helped boost rates of Tdap booster that protects against tetanus, diptheria, and whooping cough, a study shows. Guidelines recommend that adolescents and adults ages 11 and up receive a single dose of the Tdap vaccine for booster immunization even if they have had a Td (tetanus and diphtheria) vaccine within the past 10 years.

Vitamin D in teens: Don't overdo it, or bad things might happen Posted: 14 Aug 2015 06:13 AM PDT Dosing obese teens with vitamin D shows no benefits for their heart health or diabetes risk, and could have the unintended consequences of increasing cholesterol and fat-storing triglycerides. These are the latest findings in a series of studies in childhood obesity.

Study finds little improvement in mortality rate for extremely preterm infants since 2000 Posted: 14 Aug 2015 06:11 AM PDT Accurate data on how extremely preterm infants fare is important as doctors and parents face difficult decisions. A neonatologist recently took a closer look at the infant mortality rates of extremely preterm infants. Many found significant improvements in the infant mortality rate among extremely preterm infants before 2000, there has been little improvement since the turn of the century.

MicroRNA markers for Madhumeha Posted: 14 Aug 2015 04:58 AM PDT Researchers have shown the biomarker role of certain circulatory microRNAs characteristic of 'Asian Indian phenotype' in patients with type 2 diabetes.

The protein that keeps cells static is found to play a key role in cell movement Posted: 14 Aug 2015 04:57 AM PDT The protein E-Cadherin is required for groups of diverse cells to migrate together, research shows. Tumors with intermediary levels of E-Cadherin generally have a poorer prognosis, and the scientists suggest that the phenomenon of heterogeneous cell migration may be related to this.

Research examines relationship between autism and creativity Posted: 13 Aug 2015 07:22 PM PDT People with high levels of autistic traits are more likely to produce unusually creative ideas, new research confirms. While the researchers found that people with high autistic traits produced fewer responses when generating alternative solutions to a problem, the responses they did produce were more original and creative. It is the first study to find a link between autistic traits and the creative thinking processes.

Titanium rings proving problematic for emergency care doctors Posted: 13 Aug 2015 07:22 PM PDT Rings made of titanium -- an increasingly popular alternative to gold and silver -- are giving emergency doctors a headache because they are so difficult to prize off swollen fingers, reveals a case study.

Mobile technology may help people improve health behaviors Posted: 13 Aug 2015 02:12 PM PDT Smart phone apps and wearable sensors are promising for improving cardiovascular health behaviors, preliminary data suggest. Self-monitoring is a key facet of changing behavior to prevent and manage heart health. Smartphone apps and wearable sensors have the potential to encourage positive change.

How anesthesia's brain effects differ in older adults, children Posted: 13 Aug 2015 01:23 PM PDT A series of papers is detailing the different ways common anesthetics affect the brains of older patients and children, findings that could lead to improved monitoring technology and safety of general anesthesia for such patients.

Regenerating nerve tissue in spinal cord injuries Posted: 13 Aug 2015 10:05 AM PDT Researchers are exploring a new therapy using stem cells to treat spinal cord injuries within the first 14 to 30 days of injury. The therapy uses a population of cells derived from human embryonic stem cells containing progenitor cells that support nerve cells and can potentially make poorly functioning nerves function better.

Scientists discover a pathway that controls cancer cell proliferation by nutrients Posted: 13 Aug 2015 10:04 AM PDT Findings of a new study introduce new drug targets to selectively inhibit a key event in tumor cell progression. The study provides further insight into the control of mTORC1 activation, and highlights several new potential drug targets to treat human pathologies linked to mTORC1 deregulation.

Alert to biologists: Ribosomes can translate 'untranslated region' of messenger RNA Posted: 13 Aug 2015 10:00 AM PDT In what appears to be an unexpected challenge to a long-accepted fact of biology, researchers say they have found that ribosomes -- the molecular machines in all cells that build proteins -- can sometimes do so even within the so-called untranslated regions of the ribbons of genetic material known as messenger RNA (mRNA).

Low-fat diet results in more fat loss than low-carb diet in humans Posted: 13 Aug 2015 10:00 AM PDT Some of the most precise human data yet on whether cutting carbs or fat has the most benefits for losing body fat. Now, researchers show how, contrary to popular claims, restricting dietary fat can lead to greater body fat loss than carb restriction, even though a low-carb diet reduces insulin and increases fat burning.

Transplant recipients more likely to develop aggressive melanoma Posted: 13 Aug 2015 09:34 AM PDT Organ transplant recipients are twice as likely to develop melanoma as people who do not undergo a transplant, and three times more likely to die of the dangerous skin cancer, suggests new research.

Study suggests Ontario nearing UN targets to help end AIDS epidemic Posted: 13 Aug 2015 09:30 AM PDT A new study suggests Ontario is nearing ambitious United Nations targets for ending the AIDS epidemics. By 2020, 90 per cent of all people living with HIV should know their HIV status, 90 per cent of all people diagnosed with HIV are receiving sustained antiretroviral drug therapy and 90 per cent of people on ART have a very low or undetectable levels of the virus.

Birth factors may predict schizophrenia in genetic subtype of schizophrenia Posted: 13 Aug 2015 09:30 AM PDT Low birth weight and preterm birth appear to increase the risk of schizophrenia among individuals with a genetic condition called the 22q11.2 deletion syndrome, a new study shows.

Dentists tapped for new role: Drug screenings Posted: 13 Aug 2015 09:30 AM PDT A visit to the dentist has the potential to be more than a checkup of our teeth as patients are increasingly screened for medical conditions like heart disease and diabetes. A new study focuses on dental screenings for drug misuse, finding 77 percent of dentists ask patients about illicit drug use, and 54 percent of dentists believe that such screenings should be their responsibility.

New research reveals unintended consequences of using incorrect medical foods in managing patients Posted: 13 Aug 2015 09:30 AM PDT Many 'medical foods' are designed to help manage patients with rare inborn errors of metabolism, and can help prevent serious and life-threatening complications. Unfortunately such special foods may cause harm in some patients when their use is not carefully monitored. Researchers argue that such patients may need closer dietary management.

Fears of potentially blinding complication from Avastin eye injections overblown, says study Posted: 13 Aug 2015 09:30 AM PDT Eye injections of the drug Avastin, used to treat retinal diseases, bring no greater risk of endophthalmitis, a potentially blinding eye infection, than injections with the much more expensive drug Lucentis made by the same company, according to new research.

Multigene panel testing for hereditary breast/ovarian cancer risk assessment Posted: 13 Aug 2015 09:30 AM PDT Multigene testing of women negative for BRCA1 and BRCA2 found some of them harbored other harmful genetic mutations, most commonly moderate-risk breast and ovarian cancer genes and Lynch syndrome genes, which increase ovarian cancer risk, according to an article.

New study examines the link between hospital care for self-harm and risk of death Posted: 13 Aug 2015 07:43 AM PDT A study that followed up 38,415 people admitted to hospital with self-harm has, for the first time, investigated the association between the treatment patients receive in hospital and their subsequent risk of death.

Sequestered prion protein takes the good mood away, suggests new hypothesis on depression Posted: 13 Aug 2015 07:43 AM PDT The discovery of antidepressant drugs led to the first biochemical hypothesis of depression, known as the monoamine hypothesis. However, this hypothesis does not seem to fully explain the complexity of human depression. Now a new study offers one more important key that may increase our understanding of the pathogenesis behind clinical depression and neurodegenerative disorders.

Lack of ultimate meaning in life associated with alcohol abuse, drug addiction and other mental health problems Posted: 13 Aug 2015 06:29 AM PDT One of the most commonly used treatment models in addiction is the 12-step model developed in the 1930s and rooted in spirituality. Yet, surprisingly, there is no clear understanding about how to nurture spirituality among people struggling with addictions.
