Use redistricting maps to make organ allocation more equitable, researchers advocate Posted: 11 Jul 2013 12:40 PM PDT Using the same type of mathematical formulas used to draw political redistricting maps, researchers say they have developed a model that would allow for the more equitable allocation of livers from deceased donors for transplantation.

Gene therapy using lentivirus to treat Wiskott-Aldrich Syndrome promising Posted: 11 Jul 2013 11:24 AM PDT Researchers have developed a new gene therapy approach to treatment of Wiskott-Aldrich Syndrome, a fatal inherited form of immunodeficiency.

Nerves play key role in triggering prostate cancer and influencing its spread Posted: 11 Jul 2013 11:23 AM PDT Researchers have found that nerves play a critical role in both the development and spread of prostate tumors. Their findings, using both a mouse model and human prostate tissue, may lead to new ways to predict the aggressiveness of prostate cancer and to novel therapies for preventing and treating the disease.

Cry analyzer seeks clues to babies' health Posted: 11 Jul 2013 10:56 AM PDT Researchers have developed a new tool that analyzes the cries of babies, searching for clues to potential health or developmental problems. Slight variations in cries, mostly imperceptible to the human ear, can be a "window into the brain" that could allow for early intervention.

Engineers develop novel method to increase lifespan of joint replacements Posted: 11 Jul 2013 10:54 AM PDT Researchers in the United Kingdom have completed a project that will enable surgeons to fit joint replacements with longer, optimized lifespans.

Ground-breaking new method of 'starving' cancer cells Posted: 11 Jul 2013 10:54 AM PDT Researchers have discovered a novel way of killing cancer cells. The scientists found a new potential treatment for cancer, which leaves the body's healthy cells undamaged, unlike traditional therapies such as radiotherapy.

Obese dads pass on predisposition to obesity and metabolic disorders to their kids Posted: 11 Jul 2013 10:54 AM PDT If you are obese and hope to be a father, here's another reason to lose weight: your children and grandchildren may inherit your waistline or metabolic disorders. Scientists have discovered in mice that obese fathers, even those with no symptoms of diabetes, passed this negative trait on most frequently to their daughters. Sons don't dodge this genetic bullet either -- both sons and daughters of obese fathers have increased risks of developing metabolic diseases.

Whole chickens from farmers markets may have more pathogenic bacteria Posted: 11 Jul 2013 10:54 AM PDT Raw, whole chickens purchased from farmers markets throughout Pennsylvania contained significantly higher levels of bacteria that can cause foodborne illness compared to those purchased from grocery stores in the region, according to a small-scale study.

First full genome sequencing for autism: Promise for future diagnosis, prevention and treatment Posted: 11 Jul 2013 10:53 AM PDT New research has found that full genome sequencing provides the definitive look at wide ranging genetic variations associated with ASD. Inherited, de novo and X-linked genetic alterations found in one half of the affected families sequenced included four newly identified risk genes, nine known and eight candidate ASD risk genes, and in genes associated with fragile X, epilepsy or related syndromes. Some families had a combination of genes involved.

Hippo pathway to better cancer treatment? Unusual key to regulating cell growth Posted: 11 Jul 2013 10:53 AM PDT Researchers have discovered a potential new pathway to treat cancer by asking some odd questions about the size of animals.

Critical pathway in cell cycle may lead to cancer development Posted: 11 Jul 2013 10:52 AM PDT Researchers' findings on chromosome shortening suggest a potential target to arrest cancer cell growth.

Researchers regenerate retina in mice using neuronal reprogramming Posted: 11 Jul 2013 10:47 AM PDT Researchers in Spain have managed to regenerate the retina in mice using neuronal reprogramming. There are currently several lines of research that explore the possibility of tissue regeneration through cell reprogramming. One of the mechanisms being studied is reprogramming through cell fusion.

Molecular discovery puts cancer treatment in a new perspective Posted: 11 Jul 2013 08:34 AM PDT Researchers have obtained ground-breaking new knowledge about proteases - important enzymes which, among other things, play a role in the development of cancer cells. The findings may be significant for the development of cancer drugs.

Delayed puberty: First estrogen receptor mutation found in a young woman Posted: 11 Jul 2013 08:34 AM PDT A receptor mutation that essentially blocks estrogen's action has been identified for the first time in a female, researchers report.

Higher BMI increases risk of gallstones, especially in women, study finds Posted: 11 Jul 2013 08:33 AM PDT New research reveals a causal association between elevated body mass index (BMI) and increased risk of gallstone disease. Results show women are at greater risk of developing gallstones.

Factors that may cause fluctuations in deep brain stimulation levels over time Posted: 11 Jul 2013 07:33 AM PDT Deep brain stimulation therapy blocks or modulates electrical signals in the brain to improve symptoms in patients suffering from movement disorders such as Parkinson's disease, essential tremor and dystonia, but a new study suggests that several factors may cause electrical current to vary over time.

Cells in the early embryo battle each other to death for becoming part of the organism Posted: 11 Jul 2013 07:32 AM PDT Researchers have found that during the early stages of mammalian development, embryonic cells embark on a battle for survival. Through this battle, the less active of these cells are eliminated by their stronger sisters.

Ship noise impairs feeding and heightens predation risk for crabs Posted: 11 Jul 2013 07:32 AM PDT A study published in the journal Animal Behaviour found that the noise of passing ships disrupts feeding for the common shore crab. Perhaps worse, the team from the Universities of Exeter and Bristol also found that when threatened, crabs took longer to retreat to shelter and lost their natural 'play dead' behavior.

Hidden strains of HPV found in 'virus-negative' genital warts Posted: 11 Jul 2013 07:32 AM PDT Researchers assessed the DNA found in samples taken from 40 patients with 'virus-negative' genital warts. Through a general DNA sequencing approach, the researchers showed that several of the negative samples did in fact contain HPV DNA.

New insight into the human genome through the lens of evolution Posted: 11 Jul 2013 07:31 AM PDT By comparing the human genome to the genomes of 34 other mammals, Australian scientists have described an unexpectedly high proportion of functional elements conserved through evolution. While other studies have shown that around 5-8 percent of the genome is conserved at the level of DNA sequence, indicating that it is functional, the new study shows that in addition much more, possibly up to 30 percent, is also conserved at the level of RNA structure.

Acceptance of what cannot be changed predicts satisfaction in later life Posted: 11 Jul 2013 07:30 AM PDT Accepting what cannot be changed is key to happiness in old age after loss of independence. When older adults lose control as they move into residential care, they adapt and accept what cannot be changed in order to stay happy. According to a new study, when it comes to satisfaction in later life the ability to accept what cannot be changed is as important as the feeling of being able to exert control.

Prisoners doing yoga may see psychological benefits Posted: 11 Jul 2013 05:49 AM PDT Yoga can improve mood and mental wellbeing among prisoners, a new study suggests, and may also have an effect on impulsive behavior. The researchers found that prisoners after a ten-week yoga course reported improved mood, reduced stress and were better at a task related to behavior control than those who continued in their normal prison routine.

Later cord clamping after birth increases iron levels in babies Posted: 11 Jul 2013 05:49 AM PDT Delaying clamping of the umbilical cord after birth benefits newborn babies, according to a systematic review. The authors found babies' blood and iron levels were healthier when the cord was clamped later.

Do antibiotics in animal feed pose a serious risk to human health? Posted: 11 Jul 2013 05:48 AM PDT As fears rise over antibiotic resistance, two experts debate whether adding antibiotics to animal feed poses a serious risk to human health.

Combination of smoking and heavy drinking 'speeds up cognitive decline' Posted: 11 Jul 2013 05:47 AM PDT The combination of smoking and heavy drinking speeds up cognitive decline, according to new research.

Over 70% of children who drowned could not swim and were not using flotation devices, Spanish study finds Posted: 11 Jul 2013 05:45 AM PDT A recent study analyses cases of drowning attended to in 21 hospitals in Spain during the summers of 2009 and 2010. 60% of the victims were younger than six years old and more than 70% did not know how to swim and were not using flotation devices when they drowned. Furthermore, in eight in every ten cases their carers admitted to having supervised them less attentively.

Parental divorce in childhood is linked to raised inflammation in adulthood Posted: 11 Jul 2013 05:45 AM PDT People who experience parental divorce during childhood have higher levels of an inflammatory marker in the blood which is known to predict future health, according to new research from the United Kingdom.

Cells make costume changes for cardiac regeneration Posted: 11 Jul 2013 05:45 AM PDT If the heart following a heart attack is not sufficiently supplied with blood, heart tissue dies. In adult humans, the ability to heal itself is hardly developed. Scientists have now observed in the embryo of the zebrafish that muscle cells migrate from the undamaged atrium into the ventricle and thus significantly contribute to regeneration. This could serve as the basis for novel therapeutic approaches.

Surprising detail about skin cancer uncovered Posted: 11 Jul 2013 05:41 AM PDT An international team of melanoma researchers confirmed that the chances of dying from skin cancer depend strongly upon how thick the primary tumor is. But -- unexpectedly -- the team also found that those having more than one primary tumor have better survival odds.

Second ACL injuries six times more likely after reconstruction, study finds Posted: 11 Jul 2013 05:41 AM PDT Anterior cruciate ligament reconstruction (ACLR) surgery is a common knee injury procedure, but the overall incidence rate of having to go through it again within 24 months is six times greater than someone who has never had an ACL tear, according to researchers.

Kids' allergies may correlate with omega-3, omega-6 lipid levels in cord blood Posted: 10 Jul 2013 03:29 PM PDT Children with high proportions of poly-unsaturated fatty acids in cord blood at birth are more likely to develop respiratory and skin allergies in their early teens, according to new research.

New method for tracking cell signaling Posted: 10 Jul 2013 11:20 AM PDT Researchers have developed a new method for identifying the cell of origin of intracellular and secreted proteins within multicellular environments. The technique, named cell type specific labeling using amino acid precursors (CTAP), exploits the inability of vertebrate cells to synthesize essential amino acids normally required for growth and homeostasis.

Adults with eating disorders have a poorer prognosis if they suffer hyperactivity Posted: 10 Jul 2013 11:20 AM PDT A study made with 191 patients reveal that symptoms of hyperactivity due to the deficit of attention and hyperactivity disorder are associated with more impulsivity and more severity, and probably a worse prognosis in patients with eating disorders.
