Medicine & Health news

	Common gut microbe might curb multiple sclerosis risk—at least in women A common gut microbe might curb the risk of developing multiple sclerosis—at least in women—suggests the largest study of its kind published online in the Journal of Neurology Neurosurgery & Psychiatry.
	Too much sitting can be deadly—even if you exercise, review finds Regular exercise doesn't erase the higher risk of serious illness or premature death that comes from sitting too much each day, a new review reveals.
	'Fight or flight' response control center for the heart found An animal study led by Johns Hopkins investigators has uncovered what controls the ability of healthy hearts to speed up in response to circumstances ranging from fear to a jog around the block.
	On the ups and downs of the seemingly idle brain Even in its quietest moments, the brain is never "off." Instead, while under anesthesia, during slow-wave sleep, or even amid calm wakefulness, the brain's cortex maintains a cycle of activity and quiet called "up" and "down" states. A new study by Brown University neuroscientists probed deep into this somewhat mysterious cycle in mice, to learn more about how the mammalian brain accomplishes it.
	Team sheds light on genetic mutations in autism disorders Recent research has linked autism with a lack of "pruning" in developing brain connections, but a new Dartmouth study suggests instead it is the excessive growth of new connections that causes sensory overload in people with the disorder.
	Study indicates exercise sharpens the young adult brain Regular physical activity improves brain function even in young adults considered in their prime and at the height of cognitive ability, according to a new University of Otago study.
	Researchers find a novel signaling pathway involved in appetite control A new study has revealed important details of a molecular signaling system in the brain that is involved in the control of body weight and metabolism. The study, published January 19 in Nature, provides a new understanding of the melanocortin pathway and could lead to new treatments for obesity.
	Researchers open 'Pandora's box' of potential cancer biomarkers A new analysis opens the door to discovery of thousands of potential new cancer biomarkers.
	New cancer-fighting strategy would harden cells to prevent metastasis Existing cancer therapies are geared toward massacring tumor cells, but Johns Hopkins researchers propose a different strategy: subtly hardening cancer cells to prevent them from invading new areas of the body. They devised a way of screening compounds for the desired effect and have identified a compound that shows promise in fighting pancreatic cancer. Their study appears this week in the early edition of the Proceedings of the National Academy of Sciences.
	Men and women process emotions differently, brain study shows Women rate emotional images as more emotionally stimulating than men do and are more likely to remember them. However, there are no gender-related differences in emotional appraisal as far as neutral images are concerned. These were the findings of a large-scale study by a research team at the University of Basel that focused on determining the gender-dependent relationship between emotions, memory performance and brain activity. The results will be published in the latest issue of the Journal of Neuroscience.

The gut-derived hormone ghrelin is one such key regulator, promoting appetite through its effects on neurons in a small region of the brain called the hypothalamus.
	Research gives new hope for restoring cells in damaged brains and spinal cords What motivates Penn State scientists and their students to devote countless hours trying to solve tough research mysteries? For Gong Chen, a biology professor at Penn State, the answer is rooted in a desire to help relieve the suffering of patients and their loved ones.
	Immunotherapy inhibits heroin effects in research animals Immunotherapy could have a place in the treatment of substance abuse in the future. A specific antibody can reduce the acute effects of heroin, according to a new experimental study at the Norwegian Institute of Public Health.
	Fat and sugar-heavy diet harms your brain – and makes you keep on eating Do you eat only when you're actually hungry? Many of us eat even when our bodies don't need food. Just the thought of food entices us to eat. We think about food when we see other people eating, when we pass a favorite fast-food restaurant, when we see a scrumptious snack near the check-out at a convenience store. In addition, we're the targets of sophisticated advertising techniques designed to keep thoughts of food and the pleasures of eating almost constantly in our minds.
How to attack and paralyze myeloma cells Multiple myeloma is a malignant disease characterised by proliferation of clonal plasma cells in the bone marrow and typically accompanied by the secretion of monoclonal immunoglobulins that are detectable in the serum or urine. Increased understanding of the microenvironmental interactions between malignant plasma cells and the bone marrow niche, and their role in disease progression and acquisition of therapy resistance, has helped the development of novel therapeutic drugs for use in combination with cytostatic therapy.
	Dog-human cooperation is based on social skills of wolves Dogs are man's best friend and partner. The origins of this dog-human relationship were subject of a study by behavioural scientists from the Messerli Research Institute at the Vetmeduni Vienna and the Wolf Science Center. They showed that the ancestors of dogs, the wolves, are at least as attentive to members of their species and to humans as dogs are. This social skill did not emerge during domestication, as has been suggested previously, but was already present in wolves. The researchers have published a summary of their results and present their new theory in the journal Frontiers in Psychology.

Young Asians at greater skin cancer risk in Australia New research from the University of Adelaide shows that young Asian Australians could be placing themselves at greater risk of developing skin cancer by engaging in "dangerous" sun behaviour.
	Optogenetics makes sterile mice fertile again Scientists from the Center of Advanced European Studies and Research (caesar) in Bonn, an Institute of the Max Planck Society, have succeeded for the first time in controlling the function of sperm by optogenetics. They inserted a light-activated enzyme for cAMP synthesis into mouse sperm that lacked the endogenous enzyme. Sperm of these mice are usually non-motile, and the mice consequently infertile. After stimulation of these sperm with blue light, they produce cAMP, start to swim again, and are even able to fertilise eggs. Using optogenetics, the scientists are now able to control not only the influx of ions into nerve cells, and thus their activity, but also signalling pathways in other cell types.
	A very personal perspective on Dengue fever Leah Katzelnick was all set for a career as an anthropologist until she contracted dengue fever. She was in hospital for a week with severe symptoms.

	Study challenges best way to position women during childbirth New research is challenging what many obstetricians and physician anesthesiologists believe is the best way to position women during labor. According to a study published in the February issue of Anesthesiology, the official medical journal of the American Society of Anesthesiologists® (ASA®), the traditional practice of positioning women on their side, with hips tilted at 15 degrees, during labor does not effectively reduce compression of the inferior vena cava, a large vein located near the abdominal area that returns blood to the heart, as previously thought. In fact, not until the degree of tilt reached 30 degrees did blood flow only partially increase in patients, the study found.
	Poor social integration = poor health There are many benefits to being supported by a strong social network. But can having more friends actually make you healthier? New research from Concordia shows that social relationships affect not only our mental but also our physical wellbeing.
Connection between childhood adversity and psychiatric disorders seen at cellular level In a new study published online in Biological Psychiatry on January 16, 2015, researchers from Butler Hospital identify an association between biological changes on the cellular level and both childhood adversity and psychiatric disorders. These changes in the form of telomere shortening and alterations of mitochondrial DNA (mtDNA), are important in the aging process, and this new research provides evidence that psychosocial factors—specifically childhood adversity and psychiatric disorders— may also influence these cellular changes and could lead to accelerated aging.

New research defines role of long noncoding RNAs in inflammation Inflammation and immune system activation are complex processes controlled by elaborate signaling pathways and hundreds of genes that are turned on and off in response to external stimuli such as bacteria or viruses. A class of molecules called long noncoding RNAs (lncRNAs) are now emerging as important regulators of inflammatory gene expression and potential targets for novel anti-inflammatory therapeutics, as described in a Review article in Journal of Interferon & Cytokine Research (JICR).
Revolutionary back surgery technique for children with scoliosis The Sainte-Justine University Hospital Center (CHU Sainte-Justine) affiliated to Université de Montréal is now the first institution in Québec, the second in Canada and among the world's top ten to perform a revolutionary back surgery technique in children with scoliosis. The number of such surgeries performed worldwide so far is less than a hundred. Unlike any other technique, this one enables children of seven years of age and up to 14 years old to gain a straight spine, with no limitation of movement. The intervention is performed at CHU Sainte-Justine by orthopedic surgeon Dr. Stefan Parent, who also carries research with the aim of identifying those children at-risk of major curvature progression who are likely to benefit from the new surgical technique. Straightening the spine by leveraging the child's growth

The results are published online January 19, 2015 in Nature Neuroscience.
	Does gestational diabetes affect the therapeutic potential of umbilical cord-derived stem cells? Multipotent cells isolated from the human umbilical cord, called mesenchymal stromal cells (hUC-MSCs) have shown promise for use in cell therapy to treat a variety of human diseases. However, intriguing new evidence shows that hUC-MSCs isolated from women with gestational diabetes demonstrate premature aging, poorer cell growth, and altered metabolic function, as reported in an article in Stem Cells and Development.
	Patients actively warmed during surgery still experience hypothermia, study finds Body temperature decreases during the first hour of surgery, even when patients are actively warmed with forced air, reports a new study published in the February issue of Anesthesiology, the official medical journal of the American Society of Anesthesiologists (ASA). Furthermore, patients who experience the most hypothermia are more likely to require blood transfusions.
ASCO names Cancer Advance of the Year The American Society of Clinical Oncology (ASCO) for the first time announced its cancer Advance of the Year: the transformation of treatment for the most common form of adult leukemia. Until now, many patients with chronic lymphocytic leukemia (CLL) have had few effective treatment options. Four newly approved therapies, however, are poised to dramatically improve the outlook for patients with the disease.
High-dose statin may protect heart surgery patients' kidney health Acute kidney injury often arises after major surgery because the kidneys can be deprived of normal blood flow during the procedure. The use of contrast media, or dyes, can contribute to this problem.
Staff at psychiatric hospitals often face threats of physical violence In a survey of 348 workers at a large psychiatric hospital, 99% of the staff reported verbal conflict with patients, and 70% reported being assaulted during the previous 12 months. Verbal conflict with other staff was also high, at 92%.
Equation helps identify global disparities in cancer screening and treatment Disparities in cancer screening, incidence, treatment, and survival are worsening globally.
