Genome sequence cannot predict radiation resistance, say researchers

For the last two decades, researchers worldwide have been using whole genome sequencing to understand what makes cells radiation-resistant, hoping to solve an old biological mystery: why is it that one of the most radiation-resistant organisms, Deinococcus radiodurans, aka "Conan the bacterium," can survive hundreds of times more DNA damage caused by gamma rays than most other organisms? According to a study published recently in Standards of Genomic Sciences by researchers at the Uniformed Services University (USU), the amount of radiation a Deinococcus cell can survive in fact has little to do with the number and types of its DNA repair proteins.

'Metabolically healthy obese' have increased risk of cardiovascular disease events, study shows

Clinicians are being warned not to ignore the increased cardiovascular health risks of those who are classed as either 'healthy obese' or deemed to be 'normal weight' but have metabolic abnormalities such as diabetes.

Small increases in physical exercise can lower chances for major mobility loss in older adults

Adding 48 minutes of moderate exercise per week is associated with improvements in overall physical functioning and decreases in risks of immobility in older adults who are sedentary, finds a new study led by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University.

New 3D visualization of cardiac conduction system could better inform future heart surgeries

Future heart surgeries will be better informed, as cardiologists will have access to detailed information regarding the 3D disposition of the human conduction system, which is responsible for generating the heartbeat.

Two protocols help assess patients with chest pain quickly and safely in emergency departments

Two protocols for quickly and safely evaluating patients presenting to emergency departments with chest pain are being adopted by Australian hospitals.

Asian dust exposure associated with onset of myocardial infarction

A recent environmental epidemiological study by Japanese researchers has shown that Asian sand particles blown to Japan from desert areas of the Asian continent are associated with the onset of myocardial infarction.

BioCote Silver Ion Antimicrobial Technology makes surfaces inhospitable to influenza viruses

Strike a chord please, especially in light of the BMJ's article on Tuesday about the ineffectiveness of the flu vaccine for elderly last year - just wanted to make you also aware of the ultimate surface protection against viruses like H1N1, plus all the proliferating superbugs.

Most patients treated for atrial fibrillation have sleep apnea, study shows

A study involving cardiac patients at the University Hospital of Umeå shows that over 80 percent of patients treated for atrial fibrillation also have sleep apnea - a condition with pauses in breathing during sleep.

Study finds strong link between height and VTE risk

In a new study from Lund University in Sweden, researchers investigated the risk factors for blood clots, i.e. venous thromboembolism (VTE). The results show a strong correlation between height and VTE risk for both women and men. The risk increases with height.

A rare dementia gene runs in the family, but he’s fine — so far

John Janda knows he takes after his mother. At 68, the graying building contractor is sentimental, just as she was. He smiles indulgently as he shows off photos of his 9-month-old grandson; he tears up at the memory of losing his dad in a construction accident more than 40 years ago.

Researchers create first realistic model of the heart to simulate arrhythmia

A group of researchers from MIPT and Ghent University(Belgium) has developed the first realistic model able to reproduce the complexity of the cardiac microstructure.

E-cigarettes associated with increased blood pressure, heart rate, and arterial stiffness, study reveals

A new study, presented at the European Respiratory Society International Congress, suggests that use of e-cigarettes with nicotine causes arterial stiffness in humans, and has significant consequences leading to risk of heart disease and stroke later in life.

Family history may be important predictor of heart disease in South Asians

New research by UT Southwestern cardiologists shows that people of South Asian descent with a family history of coronary heart disease are significantly more likely to have high levels of calcium buildup in their arteries - an indicator of higher risk for heart attacks.

Menopausal changes have detrimental effects on sleep patterns

A recent survey of peri- and post-menopausal women in the US has highlighted the negative impact that the menopause can have on a woman's ability to get sufficient sleep.

SleepRate introduces new campaign to solve global sleep crisis

SleepRate, the developer of a comprehensive sleep improvement app, today announces the launch of the ‘Global Sleep Fix’ event, which will run between 5th September and 3rd October.

Comprehensive analysis reveals cumulative burden of chronic disease in childhood cancer survivors

The most complete assessment yet of chronic disease in adult survivors of childhood cancer found they have a nearly two-fold greater cumulative burden of chronic health problems than the general public.

Researchers find correlation between shorter telomeres and presence of heart failure

Each cell in the average human body contains 23 pairs of chromosomes, with four telomeres on each pair. Telomeres cover the end of the chromosome, protecting it from deterioration or fusion with adjacent chromosomes, much like the plastic tip at the end of a shoelace protects it from unraveling.

Relationship between emotion and health outcomes may vary by cultural context

Positive emotions are often seen as critical aspects of healthy living, but new research suggests that the link between emotion and health outcomes may vary by cultural context. The findings, published in Psychological Science, a journal of the Association for Psychological Science, show that experiencing positive emotions is linked with better cardiovascular health in the US but not in Japan.

Differentiating sepsis and systemic inflammatory response syndrome using biomarkers

Firstly, it is necessary to make a distinction between systemic inflammation and Systemic Inflammatory Response Syndrome (SIRS). SIRS consists of changes in clinical signs including an abnormal body temperature, increased heart rate, increased respiratory rate, an abnormal white cell count (either decreased or elevated), or an increase in band neutrophils.
