The median duration of both cough and chest pain was 15 days.

Need for authenticity drives gender transitions in later life, expert says

Posted: 08 Sep 2014 05:43 PM PDT

As we age, all of us begin to think about what makes us tick and what kind of legacy we want to leave. For some, this manifests itself in the purchase of a motorcycle, a boat or an exotic vacation. But for others, the issues of age and transition are a bit more contemplative. The paper examines an existential perspective on time with a notion of queer time based on the experiences of older transgender persons who contemplate or pursue a gender transition later in life.

Toward a theory of child well-being

Posted: 08 Sep 2014 05:43 PM PDT

For most of us, being healthy is more than lack of disease. It is a state of physical and mental well-being. But what is well-being? Can a comprehensive picture of well-being be established? And how can a deeper understanding of the nature of well-being help further its measurement?

Biologists delay the aging process by 'remote control'

Posted: 08 Sep 2014 12:29 PM PDT

Biologists have identified a gene that can slow the aging process when activated remotely in key organ systems. The life scientists, working with fruit flies, activated a gene called AMPK that is a key energy sensor in cells. Increasing AMPK in the intestine increased the fly's life by about 30 percent, and the fly stayed healthier longer as well. The research could have important implications for delaying aging and disease in humans.

In one of nature's innovations, a single cell smashes and rebuilds its own genome

Posted: 08 Sep 2014 12:29 PM PDT

A pond-dwelling, single-celled organism has the remarkable ability to break its own DNA into nearly a quarter-million pieces and rapidly reassemble those pieces when it's time to mate. This elaborate process could provide a template for understanding how chromosomes in more complex animals such as humans break apart and reassemble, as can happen during the onset of cancer.

Sleeping on animal fur in infancy found to reduce risk of asthma

Posted: 08 Sep 2014 05:37 AM PDT

Sleeping on animal fur in the first three months of life might reduce the risk of asthma in later childhood a new study has found. The chance of having asthma at the age of 6 years was 79% lower in children who had slept on animal skin after birth compared with those who were not exposed to animal skin. The risk decreased to 41% by the age of 10.

Taking short walking breaks found to reverse negative effects of prolonged sitting

Posted: 08 Sep 2014 05:37 AM PDT

Three easy -- one could even say slow -- 5-minute walks can reverse harm caused to leg arteries during three hours of prolonged sitting, researchers report. Sitting for long periods of time is associated with risk factors such as higher cholesterol levels and greater waist circumference that can lead to cardiovascular and metabolic disease. When people sit, slack muscles do not contract to effectively pump blood to the heart. Blood can pool in the legs and affect the endothelial function of arteries, or the ability of blood vessels to expand from increased blood flow.

Many patients in cancer centers may not experience a dignified death

Posted: 08 Sep 2014 05:37 AM PDT

Many patients in cancer centers do not experience a dignified death, a new German study that surveyed physicians and nurses suggests. The study indicates the need for cancer centers to invest more in palliative care services, adequate rooms for dying patients, staff training in end-of-life care, and advance-care-planning standards.

Father's smoking prior to conception could increase asthma risk for baby

Posted: 08 Sep 2014 05:37 AM PDT

A baby has a greater risk of asthma if his or her father smoked prior to conception, research shows. The study is the first in humans to analyze the link between a father's smoking habits before conception and a child's asthma. The findings add to growing evidence from animal studies which suggest that the father's exposures before parenthood can harm his child.

Input from psychologist can help improve asthma symptoms

Posted: 08 Sep 2014 05:37 AM PDT

Around 27% of people with severe asthma are thought to experience psychological problems'; however, this isn't routinely addressed by asthma healthcare professionals.

Breath temperature test could identify lung cancer

Posted: 08 Sep 2014 05:37 AM PDT

The temperature of exhaled breath could be used to diagnose lung cancer, according to a new study. Results of a study demonstrated that the patients with lung cancer had a higher breath temperature than those without. The temperature also increased with the number of years a person had smoked and the stage at which their lung cancer had developed.

Poor recording of physical health, medication could be causing dementia trials to fail

Posted: 08 Sep 2014 05:35 AM PDT

Dementia trials could be failing because they all too often overlook the physical health of patients, according to new research. More than 60 per cent of people with dementia are estimated to have three or more other conditions (co-morbidities). The research shows how the combined effects of co-morbidities including diabetes, lung disease, arthritis and chronic heart failure are not being adequately described in dementia trials.

Women, health professionals spark new cycle of improving maternal, newborn health

Posted: 08 Sep 2014 05:35 AM PDT

Demand for better care by women linked with the expansion of basic services, rather than political pressure, has helped to improve midwifery services in low to middle-income countries, according to international research. An examination of maternal and newborn health systems found that after initial investment in health infrastructure, a virtuous cycle developed in these countries -- with increased demand for care leading to the deployment of more midwives, better services, improved outcomes, and in-turn, more demand and investment.

Research explains how you bite off the chocolate from nuts

Posted: 08 Sep 2014 05:35 AM PDT

Simply biting off the chocolate from a nut dipped in chocolate, instead of biting through both the chocolate and nut requires sophisticated control of the biting power. This is possible owing to an advanced coordination of muscle activation and brake reflexes in different parts of the jaw muscles.

Word 'edges' are important for language acquisition

Posted: 08 Sep 2014 05:33 AM PDT

Word "edges" are important for language acquisition. Children start to learn the sound of words by remembering the first and last syllables. A new study sheds light on the information the infant brain uses during language acquisition and the format in which it stores words in its memory.

New mechanism in gene regulation revealed

Posted: 08 Sep 2014 05:33 AM PDT

The information encoded in our genes is translated into proteins, which ultimately mediate biological functions in an organism. Messenger RNA (mRNA) plays an important role, as it is the molecular template used for translation. Scientist have now unraveled a molecular mechanism of mRNA recognition, which is essential for understanding differential gene regulation in male and female organisms.

Ovarian cancer oncogene found in 'junk DNA'

Posted: 06 Sep 2014 06:30 AM PDT

A research team has mined 'junk DNA' sequences to identify a non-protein-coding RNA whose expression is linked to ovarian cancer. Using clinical, genetic, and gene expression data as filters to distinguish genes whose copy number alteration causes cancer from those for whom copy number changes are incidental, the team whittled down their list from 14,000 to a more manageable number, each of which they systematically tested using genetic experiments in animals.
