Not everyone wants cheering up, new study suggests

Posted: 24 Jun 2014 11:23 AM PDT

You may want to rethink cheering up your friends who have low self-esteem because chances are they don't want to hear it. People with low self-esteem have overly negative views of themselves, and often interpret critical feedback, romantic rejections, or unsuccessful job applications as evidence of their general unworthiness. A new study found that they likely don't want you to try to boost their spirits.

Gender differences could mean more risk for cardiovascular death

Posted: 24 Jun 2014 11:22 AM PDT

One expert is advocating the use of gender-based treatment for mitigating the cardiovascular risk factors related to diabetes. Research has shown women with Type 2 diabetes and high cholesterol are less likely than their male peers to reach treatment goals to lower their bad cholesterol, or low-density lipoprotein (LDL) cholesterol.

Prior drug use is greatest predictor of ecstasy use among U.S. high school seniors

Posted: 24 Jun 2014 10:58 AM PDT

A national sample of high school seniors was examined to determine who is currently at high risk for ecstasy use. Although ecstasy use in the U.S. is not as prevalent as in the late 1990s and early 2000s, its use remains popular among adolescents and young adults. The authors feel the popularity of ecstasy use may be related to increasing popularity of electronic dance festivals.

BMI measurement may be missing 25 percent of children who could be considered obese

Posted: 24 Jun 2014 10:57 AM PDT

Physicians using body mass index (BMI) to diagnose children as obese may be missing 25 percent of kids who have excess body fat despite a normal BMI, which can be a serious concern for long-term health, according to a study. The researchers found that BMI has high specificity in identifying pediatric obesity, meaning BMI accurately identifies children who are obese, but has a moderate sensitivity, meaning the BMI tool misses children who actually should be considered obese, according to the percent of fat in their bodies.

Role of cohesin in cancer revised by researcher

Virus kills triple negative breast cancer cells, tumor cells in mice

Posted: 24 Jun 2014 08:07 AM PDT

A virus not known to cause disease kills triple-negative breast cancer cells and killed tumors grown from these cells in mice, according to researchers. Understanding how the virus kills cancer may lead to new treatments for breast cancer. "These results are significant, since tumor necrosis -- or death -- in response to therapy is also used as the measure of an effective chemotherapeutic," one researcher said.

Cell division discovery could optimize timing of chemotherapy, explain some cancers

Posted: 24 Jun 2014 08:07 AM PDT

A new study has been able to demonstrate how the cycle of cell division in mammalian cells synchronizes with the body's own daily rhythm, its circadian clock. The study not only helps to explain why people with sustained disrupted circadian rhythms can be more susceptible to cancer, it may also help establish the optimal time of day to administer chemotherapy.

UK's National Health Service: Committed to failure?

Posted: 24 Jun 2014 08:06 AM PDT

A project has failed. So why continue to invest in it? This is a pertinent question for large organizations, like the UK National Health Service, which has a history of investing vast amounts of taxpayer's money into unrealistic and ultimately unsuccessful projects. According to business experts, organizations develop blind spots due to a perfect storm of unworkable policies and defensive behavior.

New possibilities for leukemia therapy with novel mode of leukemia cell recognition

Posted: 24 Jun 2014 08:05 AM PDT

A new class of lipids in the leukemia cells that are detected by a unique group of immune cells has been discovered by researchers. By recognizing the lipids, the immune cells stimulate an immune response to destroy the leukemia cells and suppress their growth. The newly identified mode of cancer cell recognition by the immune system opens up new possibilities for leukemia immunotherapy.

Should universities censor students on social media?

Posted: 24 Jun 2014 07:58 AM PDT

Huge increases in the use of social media by students have posed difficult ethical questions for Universities. Comments posted on sites such as Facebook are often 'stream of consciousness' thoughts, expressed with little regard to their potential impact. Sometimes, they constitute serious transgressions, including racism, homophobia, violent threats and admissions of plagiarism.  Do Universities have a duty of care to intervene for staff and student well-being?  Should freedom of speech be upheld?

Gene in brain linked to kidney cancer, researchers say

Posted: 24 Jun 2014 07:58 AM PDT

A gene known to control brain growth and development is heavily involved in promoting clear cell renal cell carcinoma, the most common form of kidney cancer, researchers are reporting.

The truth behind the '5-second rule': When in doubt, throw it out, expert says

Posted: 24 Jun 2014 07:57 AM PDT

The burger patty that slides off the plate, the ice cream treat that plops on the picnic table, the hot dog that rolls off the grill -- conventional wisdom has it that you have five seconds to pick it up before it is contaminated. Fact or folklore? "A dropped item is immediately contaminated and can't really be sanitized," explains one researcher. "When it comes to folklore, the 'five-second rule' should be replaced with 'When in doubt, throw it out.' "

Aging accelerates genomic changes, signaling challenges for personalized medicine

Posted: 24 Jun 2014 07:52 AM PDT

Aging can occur at different rates within an individual's genome, with some portions aging 100 times faster than others, research shows. This makes personalized medicine even more challenging, which makes use of genomic information to predict future diseases and treatments. With genomes continually shifting over time, the monitoring of genomic health will require more frequent measurement of patients' genomes.

Potential new treatment approach for lung cancer

Posted: 24 Jun 2014 07:52 AM PDT

More than a third of all human cancers are driven by mutations in a family of genes known as Ras. Ras has long been considered to be a target that does not respond to cancer treating drugs, but recent research suggests new possibilities. Investigators have demonstrated that targeting a metabolic dependency downstream of Ras could provide therapeutic benefit to patients with Ras-driven lung cancers.

Fat of the bone: Exercise, diabetes affect amount of fat inside bones

Posted: 24 Jun 2014 07:50 AM PDT

A new kind of imaging technique shows how exercise and diabetes drugs affect the amount of fat inside our bones, which could play roles in the health of our bones. Our bones are not stagnant, rock-like things. They change. Marrow -- the tissue inside bones -- is full of various kinds of cells. And marrow is also full of fat. The amounts of these cells and fats can decrease or increase over time. And the production of these marrow cells and fat depend on a specific type of progenitor cell called a mesenchymal stem cell.

Challenges of visual accessibility for people with low vision

Posted: 24 Jun 2014 07:50 AM PDT

New approaches and tools are needed to improve visual accessibility for people with low vision in the "real world," according to experts. Low vision is defined as chronically impaired vision that is not correctable by glasses or contact lenses and adversely affects everyday functioning. It is estimated that there are between 3.5 million and 5 million Americans with low vision, and this number is expected to increase as the population ages.

Kids' risks from toxic metals in dirt downplayed when measured with standard tools

Posted: 24 Jun 2014 07:50 AM PDT

A new laboratory method may improve risk estimates of children's soil exposures. As the study explains, soil ingestion is one of the most important pathways through which children are exposed to toxic substances. Children have higher exposure rates from soil than adults because of their hand-to-mouth behavior. As they play outside in dirt mounds and playgrounds, there is a risk that children will ingest soil particles and heavy metals which may have been underestimated by researchers to date.

Cure for HIV is a 'major scientific priority'

Posted: 24 Jun 2014 06:33 AM PDT

Huge advancements have taken place in HIV treatment and prevention over the past 10 years, but there is still no cure or vaccine. A new review shows that because of advancements in treatment, people with the virus are living longer. Overall, new infections have decreased from 3.3 million in 2002 to 2.3 million in 2012. Global AIDS-related deaths peaked at 2.3 million in 2005, decreasing to 1.6 million by 2012.

More bicyclists on road means fewer collisions, study shows

Posted: 24 Jun 2014 06:33 AM PDT

Bicyclist safety significantly increases when there are more bikes on the road, according to a study examining collisions between bicycles and motorists. This finding could be attributed to a 'safety in numbers effect.' As bicycling increases in cities across the U.S. each year, the results could have national implications. "In fact, we are beginning to find that cities with a high level of bicycling are not just safer for cyclists but for all road users," one author said. "Improving the streets to better accommodate bicycles may enhance safety for everyone."

Exploring the brain: New findings explain how eyes link to prefrontal cortex

Posted: 24 Jun 2014 06:33 AM PDT

A research team has linked how our eyes actually see the world to neurons in the prefrontal cortex of the brain. The team studied saccadic eye movements -- those movements where the eye jumps from one point of focus to another -- in an effort to determine exactly how this happens without us being overcome by our brains processing too much visual information.

Computer-aided diagnosis of rare genetic disorders from family snaps

Posted: 24 Jun 2014 06:33 AM PDT

Computer analysis of photographs could help doctors diagnose which condition a child with a rare genetic disorder has, say researchers.

Schizophrenia and cannabis use may share common genes

Posted: 24 Jun 2014 06:33 AM PDT

Genes that increase the risk of developing schizophrenia may also increase the likelihood of using cannabis, according to a new study. Previous studies have identified a link between cannabis use and schizophrenia, but it has remained unclear whether this association is due to cannabis directly increasing the risk of the disorder. The new results suggest that part of this association is due to common genes.

Facelock: New password alternative which plays to the strengths of human memory

Posted: 24 Jun 2014 06:33 AM PDT

Forgotten passwords are a serious problem for both IT managers and users. The root of the problem is a trade-off between memorability and security: simple passwords are easy to remember but easy to crack; complex passwords are hard to crack but hard to remember. A newly proposed alternative based on the psychology of face recognition was announced today. Dubbed 'Facelock', it could put an end to forgotten passwords, and protect users from prying eyes.

Sleeping sickness: the tsetse fly genome decoded

Posted: 24 Jun 2014 06:32 AM PDT

The genome of the tsetse fly has been decoded at last. Ten years of work made it possible for a consortium of 145 scientists to publish the DNA sequence for the vector for sleeping sickness. This result is highly significant as the biology of the tsetse is unique. The information contained in its genome is fundamental for better understanding and controlling the fly. Vector control is still essential for controlling the disease without a vaccine and due to difficult treatments.

Chagas' disease: A return announced

Posted: 24 Jun 2014 06:32 AM PDT

Despite deinsectization campaigns conducted in many Latin American countries, bugs called Triatoma infestans, the main vector species for Chagas' disease, are now reappearing in villages in several regions. Wild populations of Triatoma infestans are recolonizing dwellings. The latter seem very close genetically to their domestic congeners and therefore, like their domestic counterparts, are able to adapt to humans. These wild bugs thus represent a significant risk for the re-emergence of Chagas' disease, as one out of two has been shown to carry the parasite responsible for the infection.

Howzat eyesight? New study analyses how cricketers' visual skills change with age

Posted: 24 Jun 2014 06:25 AM PDT

Effect of anxiety, adrenaline, fatigue for a soccer player: Mexican study of UK players

Posted: 24 Jun 2014 06:25 AM PDT

Some of the most common injuries in soccer players are violent joint sprains and muscle strains in the legs, which are sometimes caused by anxiety and fatigue accumulated after several games in a few weeks. To verify that these are the most common injuries, a was launched study in Britain, where 91 professional soccer teams were evaluated during a tournament and recorded 6,030 lesions, of which 23 percent were in the thighs and 17 were performed in knees or ankles.

Pushing cells towards a higher pluripotency state

Posted: 24 Jun 2014 06:25 AM PDT

Stem cells have the unique ability to become any type of cell. The possibility that they can be cultured and engineered in the lab makes them an attractive option for regenerative medicine. However, some conditions that are commonly used for culturing human stem cells may render the cells unusable for clinical use. These conditions cannot be avoided, however, as they help maintain the pluripotency of the stem cells. A group of researchers has gained new insight into the role of CCL2, a chemokine known to be involved in the immune response, in the enhancement of stem cell pluripotency.

Bone loss persists two years after weight loss surgery

Posted: 23 Jun 2014 11:17 AM PDT

For at least two years after bariatric surgery, patients continue to lose bone, even after their weight stabilizes, research shows. Gastric bypass is the most common type of weight loss surgery. "The long-term consequences of this substantial bone loss are unclear, but it might put them at increased risk of fracture, or breaking a bone," said the study's principal investigator.

Air apparent: Using bubbles to reveal fertility problems

Posted: 23 Jun 2014 11:17 AM PDT

Doctors in California are the first fertility specialists in the county to use a new ultrasound technique to assess fallopian tubes by employing a mixture of saline and air bubbles that is less painful, avoids X-ray exposure and is more convenient to patients during an already vulnerable time. Using the technique, the physician delivers the mixture of saline and air bubbles into the uterus through a small catheter, which then flows into the fallopian tubes. Under ultrasound, the air bubbles are highly visible as they travel through the tubes, allowing the physician to determine if a blockage exists.

Antibiotic developed 50 years ago may be the key to fighting 'superbugs'

Posted: 23 Jun 2014 11:17 AM PDT

Novel dosing regimens for polymyxin combinations to maximize antibacterial activity and to minimize the emergence of resistance and toxicity -- this has been the focus of a recent research study.

Sharpening a test for tracing food-borne illness to source

Posted: 23 Jun 2014 10:11 AM PDT

Research could make it easier for public health investigators to determine if a case of food poisoning is an isolated incident or part of a larger outbreak. The study focuses on a test called multi-locus variable number tandem repeats variable analysis (MLVA). The test, which is increasingly used in the detection and investigation of foodborne outbreaks, analyzes specific sequences of DNA (called loci) that change rapidly enough over time to distinguish outbreak strains from other circulating strains of the bacteria but not so rapidly that connections could be masked by changes arising during the course of an outbreak.

People who are obese or former smokers more likely to follow recommended statin therapy

Posted: 23 Jun 2014 10:11 AM PDT

Lifestyle factors can help predict whether people will adhere to statin therapy for high cholesterol, a new study suggests. Among people without heart disease and diabetes, those who are overweight, obese or former smokers are more likely to adhere to statin therapy. People with cardiovascular comorbidities, heavy drinkers and extreme drinkers (people who passed out from alcohol consumption) were substantially more likely to be nonadherent than nondrinkers.
