Mothers should be cautious when discussing weight with daughters Posted: 22 Dec 2015 01:34 PM PST How should a concerned mother discuss issues of diet and weight with her daughter? Very carefully, according to a developmental psychology doctoral student.

Tooth fillings of the future may incorporate bioactive glass Posted: 22 Dec 2015 01:34 PM PST A few years from now millions of people around the world might be walking around with an unusual kind of glass in their mouth, and using it every time they eat. Engineers have made some promising findings about the ability of 'bioactive' glass to help reduce the ability of bacteria to attack composite tooth fillings -- and perhaps even provide some of the minerals needed to replace those lost to tooth decay.

Even before ACA, cancer survivors in non-expansion states had less health-care access Posted: 22 Dec 2015 01:34 PM PST Even in the health-care landscape as it existed before the ACA, cancer survivors in states without expanded Medicaid were less likely to have a personal doctor and more likely to report inability to see a doctor due to cost (odds ratios 0.76 and 1.14 respectively), says a new report.

Increased number of IVF cycles can be beneficial, findings suggest Posted: 22 Dec 2015 01:31 PM PST Although in vitro fertilization (IVF) is often limited to three or four treatment cycles, new research shows the effectiveness of extending the number of IVF cycles beyond this number, according to a study.

By asking, ;what's the worst part of this?' physicians can ease suffering Posted: 22 Dec 2015 01:30 PM PST When patients suffer, doctors tend to want to fix things and if they cannot many doctors then withdraw emotionally. But by turning toward the suffering, physicians can better help their patients and find more meaning in their work, write authors of a new report.

Space lab technology may help researchers detect early signs of cataract Posted: 22 Dec 2015 08:37 AM PST As we age, proteins in the lenses of our eyes start misbehaving: They unfold and congregate in clusters that block, scatter and distort light as it passes through the lens. A cloudy area, or cataract, forms. In a new study, scientists found that throughout our lifetime, levels of a key protein decline, and may be an early warning sign of a developing cataract. The study suggests that there is a window before cataracts develop when there may be time to intervene and prevent them.

Less financial burden for cancer patients with paid sick leave, study finds Posted: 22 Dec 2015 08:37 AM PST In a survey of more than 1,300 patients with stage 3 colorectal cancer, researchers found that only 55 percent who were employed at the time of diagnosis retained their jobs after treatment. Patients who had paid sick leave were nearly twice as likely to retain their jobs as those without paid sick leave.

Road rumble strips are a wake-up call to pull over Posted: 22 Dec 2015 08:35 AM PST Drowsy drivers are being urged to stop and take a break the first time they hit a road rumble strip these school holidays, with new research revealing the audio-tactile vibrations should be a wake-up call to pull over.

Low zinc levels may suggest potential breast-feeding problems Posted: 22 Dec 2015 08:35 AM PST Zinc levels in breast milk may be able to serve as an indicator of breast function during lactation, according to health researchers who suggest that by identifying women with abnormally low levels of zinc in breast milk, they may be able to more quickly recognize mothers who might have trouble breast-feeding.

Mechanism of an AIDS vaccine candidate filmed in vivo Posted: 22 Dec 2015 08:35 AM PST Using innovative technology, scientists have filmed in vivo the process by which an AIDS vaccine candidate triggers the immune response. This previously unseen footage clearly shows how the vaccine recruits the immune cells needed to destroy infected cells. These results shed new light on the mode of action and potential of this vaccine.

In pursuit of the causes of cardiac hypertrophy Posted: 22 Dec 2015 08:35 AM PST Specific genes are responsible for determining cell growth and differentiation during the early stages of cardiac development. Reactivation of these genes later in life can lead to an abnormal thickening of the heart muscle, say researchers who have been able to identify the underlying molecular mechanism.

Old drugs, new tricks: Medications approved for other uses also have antibiotic action Posted: 22 Dec 2015 08:34 AM PST A number of drugs already approved to treat parasitic infections, cancers, infertility and other conditions also show promise as antibiotic agents against staph and tuberculosis infections, according to a new study. Because these agents act against multiple targets within the bacteria, it may be harder for bacteria to develop resistance, say the researchers.

Pediatric medication poisonings more likely in poor, rural areas Posted: 22 Dec 2015 08:34 AM PST Children younger than 5 who live in economically disadvantaged areas had a greater risk of medication poisoning that resulted in referral to a health care facility, according to scientists. These areas were rural and experienced high unemployment, along with lower rates of high school graduation and lower household income.

Simple shell of plant virus sparks immune response against cancer Posted: 22 Dec 2015 08:31 AM PST Shells of cowpea mosaic virus inhaled into a lung tumor or injected into ovarian, colon or breast tumors, not only triggered the immune system in mice to wipe out the tumors, but provided systemic protection against metastases, scientists report.

Still a champion runner at 80: Do elite athletes have an anti-aging secret in their muscles? Posted: 22 Dec 2015 05:47 AM PST Elite runners do not experience the muscle weakening associated with aging as non-athletes do. A new study examines if their superb fitness is because their muscles have not aged.

Study uncovers inherited genetic susceptibility across 12 cancer types? Posted: 22 Dec 2015 05:47 AM PST Researchers have shed light on the hereditary elements across 12 cancer types -- showing a surprising inherited component to stomach cancer and providing some needed clarity on the consequences of certain types of mutations in well-known breast cancer susceptibility genes, BRCA1 and BRCA2.

Toxic secretions from intracranial tumor damage the inner ear Posted: 22 Dec 2015 05:47 AM PST In some cases of vestibular schwannoma, a sometimes-lethal tumor often associated with neurofibromatosis 2 (NF2), secretions from the tumor contain toxic molecules that damage the inner ear. The findings explain why some vestibular schwannomas cause hearing loss even though they are not large enough to compress nearby structures that control hearing.

Nature's masonry: First steps in how thin protein sheets form polyhedral shells Posted: 22 Dec 2015 05:20 AM PST Scientists have for the first time viewed how bacterial proteins self-assemble into thin sheets and begin to form the walls of the outer shell for nano-sized polyhedral compartments that function as specialized factories. The new insight may aid scientists who seek to tap this natural origami by designing novel compartments or using them as scaffolding for new types of nanoscale architectures, such as drug-delivery systems.

Healthy theme park meals? Posted: 22 Dec 2015 05:20 AM PST When meals at Disney World restaurants came with a fruit or vegetables instead of fries, about half of diners opted to keep the healthier option, a new study has demonstrated.

New study indicates that metformin has the potential to prevent and treat preeclampsia Posted: 22 Dec 2015 05:20 AM PST A commonly used drug for the treatment of diabetes, metformin, may have the potential to prevent and treat preeclampsia, researchers report. Metformin has long been used to treat diabetes in both non-pregnant and pregnant patients, and is considered safe during pregnancy.

Economic opportunity may have a significant effect on health behaviors, risks Posted: 21 Dec 2015 04:34 PM PST Evidence has been found that economic opportunity -- the prospect that individuals may be able to improve their economic status -- may have important effects on the health of a community. The researchers found that mortality rates were higher and that risk factors like obesity and smoking and the prevalence of hypertension and diabetes were greater in areas with the lowest levels of economic opportunity, based on a nationwide database.

'Pill mill' crackdown linked to fewer painkiller overdose deaths in Florida Posted: 21 Dec 2015 04:34 PM PST A crackdown on Florida's 'pill mills' -- clinics dispensing large quantities of prescription painkillers often for cash-only and without proper medical examinations -- appears to have dramatically reduced the number of overdose deaths in the state from these drugs and may have also led to a drop in heroin overdose deaths, new research suggests.

Mothers-to-be, babies benefit from group prenatal care, study finds Posted: 21 Dec 2015 04:34 PM PST Group prenatal care can substantially improve health outcomes for both mothers and their infants, a new study has found. Women who received group -- rather than individual -- prenatal care were 33% less likely to have infants who were small for gestational age, had reduced risk for preterm delivery and low birthweight, and babies born to these women also spent fewer days in the neonatal intensive care unit.

Radial access used less than femoral approach for emergency angioplasty Posted: 21 Dec 2015 04:34 PM PST Although using the radial artery as the access point for angioplasty has been linked to reduced bleeding compared to use of the femoral artery, only a small number of high-risk heart attack patients who undergo rescue angioplasty -- emergency procedures following failed therapy with clot-busting drugs -- are treated by radial access, according to a study.

Chances of good outcome after stroke reduced by delays in restoring blood flow Posted: 21 Dec 2015 10:36 AM PST Delays in restoring blood flow after a stroke were associated with decreased benefits of intra-arterial clot-busting treatment and reduced chances for a good outcome, according to a new study.

Peering Under the Hood Into the Workings of Molecular Motors Posted: 21 Dec 2015 08:15 AM PST Understanding how tiny molecular motors called myosins use energy to fuel biological tasks like contracting muscles could lead to therapies for muscle diseases and cancers, say a team of researchers.

How the brain wakes you up Posted: 21 Dec 2015 08:14 AM PST A mechanism that is responsible for the rapid arousal from sleep and anesthesia in the brain has been discovered by researchers. The results of their study suggest new strategies for the medical treatment of sleep disorders and recovery of consciousness in vegetative states.

New target for potential blood cancer treatment Posted: 21 Dec 2015 08:14 AM PST Mutations present in a blood cancer known as follicular lymphoma have revealed new molecular targets for potential treatments, according to researchers.

New genetic clues to age-related macular degeneration Posted: 21 Dec 2015 08:14 AM PST An international study has significantly expanded the number of genetic factors known to play a role in age-related macular degeneration (AMD), a leading cause of vision loss among people age 50 and older. Researchers hope the findings may help improve the understanding of the biological processes that lead to AMD and identify new therapeutic targets for potential drug development.
