Living near major traffic linked to higher risk of dementia Posted: 04 Jan 2017 04:23 PM PST People who live close to high-traffic roadways face a higher risk of developing dementia than those who live further away, new research has found.

Liquid nicotine for electronic cigarettes is toxic for kids Posted: 04 Jan 2017 12:43 PM PST A 6-year-old child who accidentally swallowed liquid nicotine intended for her parents' electronic cigarettes required immediate emergency medical treatment that included intubation and an overnight stay in a pediatric intensive care unit.

Cardiovascular benefits continue five years after weight loss program Posted: 04 Jan 2017 12:43 PM PST Participants in the Why WAIT (Weight Achievement and Intensive Management) program lost substantial amounts of weight, and even those who maintained relatively little loss of weight after five years demonstrated reduced risks of cardiovascular disease.

New mechanism for Type IV pili retraction in Vibrio cholerae Posted: 04 Jan 2017 12:43 PM PST Although pathogenic bacteria often rely on a specialized molecular motor to retract their pili, a new study reveals that a minor pilin protein elicits pilus retraction in the cholera bacterium, Vibrio cholerae.

Immunotherapy, gene therapy combination shows promise against glioblastoma Posted: 04 Jan 2017 11:36 AM PST In a new study, gene therapy deployed with immune checkpoint inhibitors demonstrates potential benefit for devastating brain cancer.

Scientists tissue-engineer functional part of human stomach in laboratory Posted: 04 Jan 2017 10:35 AM PST Scientists have used pluripotent stem cells to generate human stomach tissues in a Petri dish that produce acid and digestive enzymes. They grew tissues from the stomach's corpus/fundus region. The study comes two years after the same team generated the stomach's hormone-producing region (the antrum). The discovery means investigators now can grow both parts of the human stomach to study disease.

Most younger adults with high LDL-C levels do not take a statin Posted: 04 Jan 2017 10:35 AM PST Despite recommendations, less than 45 percent of adults younger than 40 years with an elevated low-density lipoprotein cholesterol (LDL-C) level of 190 mg/dL or greater receive a prescription for a statin, according to a new study.

New sensor integrates inflammatory bowel disease detection into colonoscopy procedure Posted: 04 Jan 2017 08:43 AM PST Researchers have developed the first sensor capable of objectively identifying inflammatory bowel disease (IBD) and distinguishing between its two subtypes.

Corporal punishment viewed as more acceptable and effective when referred to as spanking Posted: 04 Jan 2017 08:43 AM PST Corporal punishment is viewed as more acceptable and effective when called spanking, according to a new study. Parents and nonparents alike judged identical acts of a child's misbehavior and the subsequent corporal punishment more favorably when called 'spank' or 'swat' rather than 'slap,' 'hit' or 'beat.' The findings indicate that people buffer negative views of corporal punishment by calling it a more culturally acceptable, less violent label, the researchers said.

Increased reaction to stress linked to gastrointestinal issues in children with autism Posted: 04 Jan 2017 08:43 AM PST One in 45 American children lives with autism spectrum disorder, according to the Centers for Disease Control and Prevention. Many of these children also have significant gastrointestinal issues, but the cause of these symptoms is unknown. Now, researchers suggest that the gastrointestinal issues in these individuals with autism may be related to an increased reaction to stress. The researchers hope the finding could lead to better treatments.

Factors responsible for chronic nature of autoimmune disease identified Posted: 04 Jan 2017 08:43 AM PST Researchers have uncovered two factors responsible for the chronic, lifelong nature of autoimmune disorders, which tend to flare up intermittently in affected patients.

High fiber diets may alleviate inflammation caused by gout Posted: 04 Jan 2017 08:43 AM PST New research shows that a high-fiber diet likely inhibits gout-related inflammation caused by monosodium urate (MSU) crystals.

Promising new drug stops spread of melanoma by 90 percent Posted: 04 Jan 2017 07:36 AM PST Researchers have discovered that a chemical compound, and potential new drug, reduces the spread of melanoma cells by up to 90 percent.

How we know Zika virus causes Guillain-Barre Syndrome and birth defects Posted: 04 Jan 2017 07:36 AM PST A structured analysis of the evidence confirms that infection with mosquito-borne Zika virus is a cause of the neurological disorder Guillain-Barre Syndrome (GBS), in addition to microcephaly and other congenital brain abnormalities, according to a systematic review.

Scientists discover a molecular motor has a 'gear' for directional switching Posted: 04 Jan 2017 07:35 AM PST A new study offers a new understanding of the complex cellular machinery that animal and fungi cells use to ensure normal cell division, and scientists say it could one day lead to new treatment approaches for certain types of cancers.

Witnessing fear in others can physically change brain Posted: 04 Jan 2017 07:35 AM PST Scientists have discovered that observing fear in others may change how information flows in the brain. The finding in a rodent model may have bearing on people who suffer post-traumatic stress disorder.

Vitamin D deficiency increases risk of chronic headache Posted: 04 Jan 2017 07:35 AM PST Vitamin D deficiency may increase the risk of chronic headache, according to a new study.

Scientists develop new antibiotic for gonorrhea Posted: 04 Jan 2017 07:35 AM PST Scientists have harnessed the therapeutic effects of carbon monoxide-releasing molecules to develop a new antibiotic which could be used to treat the sexually transmitted infection gonorrhea.

Out in the cold: Why are the oldest people the most excluded? Posted: 04 Jan 2017 07:35 AM PST People over the age of 85 are significantly more likely to suffer social exclusion than those in the 65 to 84-year-old bracket, according to new research. In a study of 10,000 people aged over 65, social policy researchers found the 'oldest old' -- those 85 and over -- have more trouble accessing services such as healthcare and food shops, with 16 percent reporting 'significant' problems, compared with only four percent of their younger counterparts.

Alcohol abuse increases risk of heart conditions as much as other risk factors Posted: 02 Jan 2017 11:36 AM PST Alcohol abuse increases the risk of atrial fibrillation, heart attack and congestive heart failure as much as other well-established risk factors such as high blood pressure, diabetes, smoking and obesity, according to a new study.
