Study shows how structural differences in the brain may relate to behavior differences in males and females

Differences in the neural wiring across development of men and women across ages, matched behavioral differences commonly associated with each of the sexes, according to an imaging-based study from researchers at the Perelman School of Medicine at the University of Pennsylvania published February 1 in Philosophical Transactions of the Royal Society B.

Researchers find new mutation signature in cancer cells

Mutations are the replacement of DNA bases known as Adenine (A), Cytosine (C), Guanine (G) and Thymine (T) with other bases. When mutations such as C to T or G to A are found within a specific DNA sequence, this is known as a mutation signature.

Certain gene variants influence what we eat

If you're fat, can you blame it on your genes? The answer is a qualified yes. Maybe. Under certain circumstances. Researchers are moving towards a better understanding of some of the roots of obesity.

Mayo Clinic researchers discover new bacterial species that triggers Lyme disease in people

Mayo Clinic researchers, in collaboration with the Centers for Disease Control and Prevention and health officials from Minnesota, North Dakota and Wisconsin, have discovered a new bacterial species that causes Lyme disease in people. The new species has been provisionally named Borrelia mayonii. Prior to this finding, the only species believed to cause Lyme disease in North America was Borrelia burgdorferi.

Older people could be at greater risk for negative consequences of consuming high-salt diet

Aging is associated with a number of changes that cause the body to function less efficiently, including the way the body controls water and sodium levels. Research has shown that as humans and animals age, they are less able to regulate sodium and water retention, urine concentration and thirst compared to their younger counterparts.

Study reveals link between genomic instability, aneuploidy and cancer

A recent analysis of 43,205 human tumours unveiled that 68% of solid tumours are aneuploid, that is to say, they have an altered number of chromosomes. In recent years, scientists have attempted to clarify whether this aneuploidy contributes to tumour development or whether it is a co-lateral effect of the genomic instability of cancer cells, which increase the rate of mutations and the likelihood of cancer.

$Certain genes could lead to stress fracture injuries$

Certain genes could lead to stress fracture injuries

In a paper published in The Official Journal of the International Purine Club University of Liverpool researchers have successfully identified how certain genes can contribute towards a person's susceptibility to stress fracture injuries. This research provides a platform for further research into providing a personalised health approach to this common sports injury.

Patients with COPD show decreased gray matter volume in certain areas of the brain

Chronic Obstructive Pulmonary Disease (COPD), a condition impacting nearly 24 million Americans, is often associated with disease-specific fears and avoidance of physical activity. Little is known of the structural brain processes that occur in COPD patients. A study published in the February issue of the journal CHEST found that patients with COPD demonstrated gray matter decreases in areas of the brain that process breathlessness, fear and sensitivity to pain.

Some heart disease drugs, antibiotics show promising perspectives in treating cancers

North American researchers have identified drugs that showed promising perspectives in treating cancers, according to a recent study published in Cancer Research.

New technique allows better understanding of cellular stress reaction

Stress in the body's cells is both the cause and consequence of inflammatory diseases or cancer. The cells react to stress to protect themselves. Researchers at the University of Zurich have now developed a new technique that allows studying a fundamental response to stress in much more detail than previously possible: the ADP-ribosylation of chromatin.

Taste deficits appear to be more prevalent in MS patients

Taste deficits appear to be more prevalent among multiple sclerosis (MS) patients than previously reported and correlate with brain lesions left by the debilitating disease, a new study from the University of Pennsylvania's Smell and Taste Center and the department of Radiology found.

Study provides insights into molecular basis of Frank-Starling regulatory mechanism

In a finding that could lead to new drugs to treat heart failure, researchers have uncovered the molecular mechanism that regulates how the heart pumps blood.

Vanderbilt researchers use cotton candy machines to produce artificial capillary system

For several years, Leon Bellan, assistant professor of mechanical engineering at Vanderbilt University, has been tinkering with cotton candy machines, getting them to spin out networks of tiny threads comparable in size, density and complexity to the patterns formed by capillaries - the tiny, thin-walled vessels that deliver oxygen and nutrients to cells and carry away waste.

New study pinpoints two tiny clusters of neurons responsible for changing normal breaths into sighs

"You must remember this: a kiss is just a kiss, a sigh is just a sigh." Contrary to the words immortalized by the piano singer in "Casablanca," a sigh is far more than a sigh. Heaving an unconscious sigh is a life-sustaining reflex that helps preserve lung function.

New discovery takes medical professionals a leap forward to effectively diagnose Alzheimer's disease

Medical professionals have to conduct a long series of tests to assess a patient's memory impairment and cognitive skills, functional abilities, and behavioral changes to accurately diagnose Alzheimer's disease. They also have to execute costly brain imagining scans and even, sometimes, invasive cerebral spinal fluid tests to rule out other diseases. The process is laborious at best -- and subjective at worst.

Abnormal breakage of chromosomes in white blood cells triggers aggressive form of ALL

A research team led by St. Jude Children's Research Hospital scientists has discovered details of how the abnormal breakage and rearrangement of chromosomes in white blood cells triggers a particularly aggressive form of acute lymphoblastic leukemia (ALL). Such leukemias are cancers of white blood cells, in which genetic mutations trigger overproduction of immature cells, called lymphoblasts.
