Do Soft Drinks Worsen COPD? Or Make Kids Violent?

***Stem Cells in Urine Easy to Isolate and Have Potential for Numerous Therapies 

Could harvesting stem cells for therapy one day be as simple as asking patients for a urine sample? Researchers at Wake Forest Baptist Medical Center’s Institute for Regenerative Medicine and colleagues have identified stem cells in urine that can be directed to become multiple cell types. 

***Increased Fluctuation in Blood Pressure Linked to Impaired Cognitive Function in Older People 

Higher variability in visit-to-visit blood pressure readings, independent of average blood pressure, could be related to impaired cognitive function in old age in those already at high risk of cardiovascular disease, suggests a a new article. 

***High Blood Pressure Linked To Memory Problems In Middle Age 

High blood pressure is linked to memory problems in people over 45, according to research published in the August 25, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology. 

***Number One Source for New Teeth 

Stem cells derived from urine can be used to generate tooth-like structures, reports a study published this week in the open access Cell Regeneration Journal. It’s thought the technique might one day help researchers grow new, tailor-made teeth for dental patients. 

***Chocolate May Help Keep Brain Healthy 

Drinking two cups of hot chocolate a day may help older people keep their brains healthy and their thinking skills sharp, according to a study published in the August 7, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. 

***Cognitive Decline With Age Is Normal, Routine, but Not Inevitable 

If you forget where you put your car keys and you can’t seem to remember things as well as you used to, the problem may well be with the GluN2B subunits in your NMDA receptors. 

***You age as you eat – Study shows link between sugars and aging 

The skin care industry is full of studies looking at sun protection and how UV rays age the skin, however new research reveals there is a link between the sugars in foods we eat and the wrinkles we find on our faces and bodies. 

***Blocking sugar intake may reduce cancer risk or progression in obese and diabetic people 

Blocking dietary sugar and its activity in tumor cells may reduce cancer risk and progression, according to researchers from the Icahn School of Medicine. The study, conducted in fruit flies and published in the journal Cell, provides insight as to why metabolism-related diseases such as diabetes or obesity are associated with certain types of cancer, including pancreatic, breast, liver, and colon cancers (see also Proinsulin). 

***Coffee and Tea May Contribute to a Healthy Liver 

Surprise! Your morning cup of tea or coffee may be doing more than just perking you up before work. 

***Soft Drinks Linked to Behavioral Problems in Young Children 

Americans buy more soft drinks per capita than people in any other country. These drinks are consumed by individuals of all ages, including very young children. Although soft drink consumption is associated with aggression, depression, and suicidal thoughts in adolescents, the relationship had not been evaluated in younger children. A new study scheduled for publication in The Journal of Pediatrics finds that aggression, attention problems, and withdrawal behavior are all associated with soft drink consumption in young children. 

***A New Wrinkle in Parkinson’s Disease Research: Skin Cream Ingredient May Stop Effects of Parkinson’s On Brain Cells 

The active ingredient in an over-the-counter skin cream might do more than prevent wrinkles. Scientists have discovered that the drug, called kinetin, also slows or stops the effects of Parkinson’s disease on brain cells. 

***Facebook Use Predicts Declines in Happiness, New Study Finds 

Facebook helps people feel connected, but it doesn’t necessarily make them happier, a new study shows. Facebook use actually predicts declines in a user’s well-being, according to a University of Michigan study that is the first known published research examining Facebook influence on happiness and satisfaction. 

***Exercise reorganizes the brain to be more resilient to stress 

Physical activity reorganizes the brain so that its response to stress is reduced and anxiety is less likely to interfere with normal brain function, according to a research team based at Princeton University. 

***Weekly Soft Drink Consumption Bubbles Up Knee Osteoarthritis; Especially in Men 

Sugary soft drink consumption contributes not only to weight gain, but also may play a role in the progression of knee osteoarthritis, especially in men, according to new research findings presented this week at the American College of Rheumatology Annual Meeting in Washington, D.C. 

***Drinking Large Amounts of Soft Drinks Associated With Asthma and COPD 

A new study published in the journal Respirology reveals that a high level of soft drink consumption is associated with asthma and/or chronic obstructive pulmonary disease (COPD) 

***Are Diet Soft Drinks Bad for You? 

A new study finds a potential link between daily consumption of diet soft drinks and the risk of vascular events. 

***High Fizzy Soft Drink Consumption Linked to Violence Among Teens 

Teens who drink more than five cans of non-diet, fizzy soft drinks every week are significantly more likely to behave aggressively, suggests research published online in Injury Prevention. This includes carrying a weapon and perpetrating violence against peers and siblings. 

***‘Mini Human Brains’ Created: Scientists Grow Human Brain Tissue in 3-D Culture System

Complex human brain tissue has been successfully developed in a three-dimensional culture system established in an Austrian laboratory. The method described in the current issue of Nature allows pluripotent stem cells to develop into cerebral organoids — or “mini brains” — that consist of several discrete brain regions.
