Whole genome or exome sequencing: An individual insight Posted: 26 Jun 2013 06:19 PM PDT Focusing on parts rather than the whole, when it comes to genome sequencing, might be extremely useful, finds new research. The research compares several sequencing technologies in the same individual with Charcot-Marie-Tooth disease (CMT), and shows that sequencing the coding regions alone at high depth of coverage can identify the genetic variation behind this disease, and was also able to resolve previous ambiguities. Next generation sequencing for understanding human DNA variation and genetic disorders is advancing in leaps and bounds.

People's perception of the effect of stress on their health is linked to risk of heart attacks Posted: 26 Jun 2013 06:19 PM PDT People who believe that stress is having an adverse impact on their health are probably right, because they have an increased risk of suffering a heart attack, according to new research.

Zebrafish study paves the way for new treatments for genetic disorder Posted: 26 Jun 2013 03:40 PM PDT Scientists have paved the way for new treatments for a common genetic disorder thanks to pioneering research on zebrafish -- an animal capable of mending its own heart.

Simple two-drug combination proves effective in reducing risk of stroke Posted: 26 Jun 2013 03:40 PM PDT Results of a Phase III clinical trial showed that a simple drug regimen of two anti-clotting drugs -- clopidogrel and aspirin -- lowered the risk of stroke by almost one-third, compared to the standard therapy of aspirin alone, when given to patients who had minor or transient stroke symptoms to prevent subsequent attacks.

Hold the medicinal lettuce Posted: 26 Jun 2013 03:39 PM PDT New research suggests that bits of genetic material from plants eaten by mice can NOT enter the bloodstream intact as previous research from another institution had indicated.

People with a disability more likely to be obese, have chronic illnesses Posted: 26 Jun 2013 03:39 PM PDT Adults with a disability are more likely to be obese or extremely obese than those without a disability according to a new study.

Salmonella infection is a battle between good and bad bacteria in the gut Posted: 26 Jun 2013 03:39 PM PDT A new study that examined food poisoning infection as-it-happens in mice revealed harmful bacteria, such as a common type of Salmonella, takes over beneficial bacteria within the gut amid previously unseen changes to the gut environment. The results provide new insights into the course of infection and could lead to better prevention or new treatments.

Researchers find zinc's crucial pathway to the brain Posted: 26 Jun 2013 01:28 PM PDT A new study helps explain how parts of the brain maintain their delicate balance of zinc, an element required in minute but crucial doses, particularly during embryonic development.

Antibiotics: Change route of delivery to mitigate resistance Posted: 26 Jun 2013 01:28 PM PDT New research suggests that the rapid rise of antibiotic resistance correlates with oral ingestion of antibiotics, raising the possibility that other routes of administration could reduce the spread of resistance.

Have a brain injury? You may be at higher risk for stroke Posted: 26 Jun 2013 01:26 PM PDT People who have a traumatic brain injury (TBI) may be more likely to have a future stroke, according to new research.

New brain imaging study provides support for the notion of food addiction Posted: 26 Jun 2013 12:39 PM PDT Consuming highly processed carbohydrates can cause excess hunger and stimulate brain regions involved in reward and cravings, according to a new study. These findings suggest that limiting these "high-glycemic index" foods could help obese individuals avoid overeating.

DNA found outside genes plays largely unknown, potentially vital roles: Thousands of previously unknown RNA molecules identified Posted: 26 Jun 2013 11:31 AM PDT A new study highlights the potential importance of the vast majority of human DNA that lies outside of genes within the cell.

Ingested nanoparticle toxicity Posted: 26 Jun 2013 11:31 AM PDT Ingestion of commonly encountered nanoparticles at typical environmental levels is unlikely to cause overt toxicity, according to US researchers. Nevertheless there is insufficient evidence to determine whether chronic exposures could lead to subtle alterations in intestinal immune function, protein profiles, or microbial balance.

People prefer 'carrots' to 'sticks' when it comes to healthcare incentives Posted: 26 Jun 2013 11:31 AM PDT To keep costs low, companies often incentivize healthy lifestyles. Now, new research suggests that how these incentives are framed -- as benefits for healthy-weight people or penalties for overweight people -- makes a big difference. The research shows that policies that carry higher premiums for overweight individuals are perceived as punishing and stigmatizing.

Potential therapeutic approach to Alzheimer's disease Posted: 26 Jun 2013 11:31 AM PDT Scientists have demonstrated a new potential target in the fight against Alzheimer's and other neurodegenerative diseases in two mouse models.

Unraveling the largest outbreak of fungal infections associated with contaminated steroid injections Posted: 26 Jun 2013 08:35 AM PDT Investigators from the Centers for Disease Control and Prevention describe pathologic findings from 40 case reports of fungal infection in patients who had been given contaminated epidural, paraspinal, or intra-articular (into joints) steroid injections and correlate these findings with clinical and laboratory data. The report alerts clinicians and the general public to the catastrophic dangers of contaminated epidural injections.

Calcium and vitamin D help hormones help bones Posted: 26 Jun 2013 08:35 AM PDT Should women take calcium and vitamin D supplements after menopause for bone health? Recommendations conflict, and opinions are strong. But now, an analysis from the major Women's Health Initiative trial throws weight on the supplement side -- at least for women taking hormones after menopause.

How does pedestrian head-loading affect the health of women and children in sub-Saharan Africa? Posted: 26 Jun 2013 08:34 AM PDT A new paper looks at how the practice of head-loading can affect the health of women and children, with a focus on sub-Saharan Africa.

Sailors most often injure their knees -- on land Posted: 26 Jun 2013 08:33 AM PDT The knees are the body part that is injured the most by dinghy sailors. The injuries are primarily due to overstrain and most often occur during physical training, according to a study by researchers in Sweden.

Teenage physical fitness reduces the risk of suicidal behavior later in life Posted: 26 Jun 2013 08:33 AM PDT Being in good physical shape at 18 years of age can be linked with a reduced risk of attempted suicide later in life. So says a study of over one million Swedish men.

Study ranks social contacts by job and social group in bid to fight infectious diseases Posted: 25 Jun 2013 04:25 PM PDT In the light of Novel Corona Virus, concerns over H7N9 Influenza in S.E. Asia, and more familiar infections such as measles and seasonal influenza, it is as important as ever to be able to predict and understand how infections transmit through populations. Researchers in the UK have mapped the daily contact networks of thousands of individuals to shed light on which groups may be at highest risk of contracting and spreading respiratory diseases.

Technique to promote nerve regeneration after spinal cord injury restores bladder function in rats Posted: 25 Jun 2013 02:23 PM PDT Using a novel technique to promote the regeneration of nerve cells across the site of severe spinal cord injury, researchers have restored bladder function in paralyzed adult rats, according to a new study. The findings may guide future efforts to restore other functions lost after spinal cord injury. It also raises hope that similar strategies could one day be used to restore bladder function in people with severe spinal cord injuries.
