Empathetic Children More Likely To Effectively Manage Stress, Behave Prosocially
Date: Aug-04-2012Infants innately relieve stress by crying, turning their heads or maintaining eye contact. Adults manage emotional tension using problem-solving or by seeking support. A new study by a University of Missouri human development expert describes how adolescents' developing personalities and coping habits affect their behaviors toward others. "We're each born with some personality tendencies; for example, we see that babies are fussy or calm," said Gustavo Carlo, the Millsap Professor of Diversity in the MU Department of Human Development and Family Studies...
Scientists Uncover A Reproduction Conundrum: For Sperm, Faster Isn't Always Better
Date: Aug-04-2012When it comes to sperm meeting eggs in sexual reproduction, conventional wisdom holds that the fastest swimming sperm are most likely to succeed in their quest to fertilize eggs. That wisdom was turned upside down in a new study of sperm competition in fruit flies (Drosophila melanogaster), which found that slower and/or longer sperm outcompete their faster rivals. The study, recently published online in Current Biology and forthcoming in print on Sept...
For Infant Sleep Safety, Beware Of Internet Searches
Date: Aug-04-2012In 2010, 59% of the U.S. population used internet searches for health information, and parents searching for information regarding their children were among the top users. In 2011, the American Academy of Pediatrics (AAP) published recommendations for infant sleep safety to reduce the risk of sudden infant death syndrome (SIDS), suffocation, strangulation, and other accidental sleep-related deaths. However, according to a study scheduled for publication in The Journal of Pediatrics, Google internet searches related to infant sleep safety often do not reflect AAP recommendations...
High Prevalence Of Recurring Shoulder Instability Injuries Among Young Athletes Playing Contact Sports
Date: Aug-04-2012Summer is a peak season for many sports, and with that comes sport-related injuries. Among those injuries is shoulder joint dislocation. According to a literature review in the August 2012 issue of the Journal of the American Academy of Orthopaedic Surgeons, most incidences of shoulder joint instability are the result of traumatic contact injuries like force or falling on an outstretched arm; a direct blow to the shoulder area; forceful throwing, lifting or hitting; or contact with another player...
Researchers Develop First Potential Medicine For Patients With Most Severe Form Of Congenital Hyperinsulinism
Date: Aug-04-2012A pilot study in adolescents and adults has found that an investigational drug shows promise as the first potential medical treatment for children with the severest type of congenital hyperinsulinism, a rare but potentially devastating disease in which gene mutations cause insulin levels to become dangerously high. "There is currently no effective medicine for children with the most common and most severe form of hyperinsulinism," said study leader Diva D. De Leon, M.D., a pediatric endocrinologist at The Children's Hospital of Philadelphia...
Improved Diagnosis For Essential Tremor
Date: Aug-04-2012Researchers at the University of Montreal and its affiliated CHU Sainte-Justine and CHUM hospitals have linked some cases of Essential Tremor (ET) to a specific genetic problem. ET is the most common movement disorder, becoming increasingly frequent with increasing age, which is characterized by an involuntary shaking movement (tremor) that occurs with motion, particularly when doing precise fine movement. The researchers published their findings tomorrow in The American Journal of Human Genetics...
New Method Could Enable Reprogramming Of Mammalian Cells
Date: Aug-04-2012Through the assembly of genetic components into "circuits" that perform logical operations in living cells, synthetic biologists aim to artificially empower cells to solve critical problems in medicine, energy and the environment. To succeed, however, they'll need far more reliable genetic components than the small number of "off-the-shelf" bacterial parts now available. Now a new method developed by Boston University biomedical engineers Ahmad S. Khalil and James J...
How Protein Component That Enables Cell Replication Gets Ferried To Chromosome Tips
Date: Aug-04-2012Stem cells are special. Nestled in muscle and skin, organ and bone, they bide their time over years or decades until called to replace damaged or lost tissue. One secret to their longevity is an enzyme called telomerase, which stills the relentless ticking of the molecular clock that limits the life span of other cells. This cellular fountain of youth prevents the progressive shortening of the tips of our chromosomes that occurs with each cell division...
Focusing On Strengths Improves Social Skills Of Adolescents With Autism
Date: Aug-04-2012The junior high and high school years are emotionally challenging even under the best of circumstances, but for adolescents with autism spectrum disorders (ASD), that time can be particularly painful. Lacking the social skills that enable them to interact successfully with their peers, these students are often ostracized and even bullied by their classmates...
Body Tremors Have A Genetic Cause
Date: Aug-03-2012Essential tremor (ET), an involuntary shaking movement (tremor) that occurs with motion, especially when performing precise fine movement, is the most prevalent movement disorder, and it becomes increasingly frequent with increasing age. The latest issue of The American Journal of Human Genetics now reveals that researchers from Montreal University and its affiliated CHU Sainte-Justine and CHUM hospitals have managed to link some cases of Essential Tremor (ET) to a specific genetic problem...
