Chemical compound shows promise as alternative to opioid pain relievers

A drug targeting a protein complex containing two different types of opioid receptors may be an effective alternative to morphine and other opioid pain medications, without any of the side effects or risk of dependence, according to research led by the Icahn School of Medicine at Mount Sinai. The findings are published in July in the journal Proceedings of the National Academy of Sciences.

How cranberries impact infection-causing bacteria

Consuming cranberry products has been anecdotally associated with prevention of urinary tract infections (UTIs) for over 100 years. But is this popular belief a myth, or scientific fact?

In recent years, some studies have suggested that cranberries prevent UTIs by hindering bacteria from sticking to the walls of the urinary tract, thanks to phytochemicals known as proanthocyanidins (PACs). Yet the mechanisms by which cranberry materials may alter bacterial behaviour have not been fully understood.

RI Hospital study: Lunar cycle affects cardiac patients undergoing acute aortic dissection

PROVIDENCE, R.I. – If you need cardiac surgery in the future, aortic dissection in particular, reach for the moon. Or at least try to schedule your surgery around its cycle. According to a study at Rhode Island Hospital, acute aortic dissection (AAD) repair performed in the waning full moon appears to reduce the odds of death, and a full moon was associated with shorter length of stay (LOS). The study is published online in advance of print in the journal Interactive Cardiovascular and Thoracic Surgery.

Adult brown fat levels increased with cold acclimation

Brown adipose tissue or brown fat is abundant in newborns, providing them with body heat, and naturally decreases with age. Recent studies have shown that adults with detectable levels of brown fat have lowered rates of obesity and higher resting metabolic rates. In the Journal of Clinical Investigation, Anouk van der Lans and colleagues at Maastrricht University and Takeshi Yoneshiro and colleagues at Hokkaido University investigate therapies for increasing brown fat activity in adults.

An 'obesity-risk' allele alters hunger-stimulating hormone production

Individuals carrying the "obesity-risk" allele of the fat mass and obesity associated gene, FTO, are prone to obesity and obesity related eating behaviors such as increased food consumption, preference for high fat foods and lack of satiation after eating. How this particular gene regulates obesity prone behaviors is not fully understood.

Current blood transfusion practice in trauma centers feasible but wastes scarce plasma

The use of a 1:1:1 blood transfusion protocol in patients with severe trauma is feasible in hospitals, although it is associated with higher waste of plasma, according to a randomized trial published in CMAJ (Canadian Medical Association Journal).

Understanding the role of IKACh in cardiac function

Researchers have uncovered a previously unknown role for the acetylcholine-activated inward-rectifying potassium current (IKACh) in cardiac pacemaker activity and heart rate regulation, according to a study in The Journal of General Physiology.

Solving DNA puzzles is overwhelming computer systems, researchers warn

Imagine millions of jigsaw puzzle pieces scattered across a football field, with too few people and too little time available to assemble the picture.

Dad's obesity could be inherited by multiple generations

The sperm of obese fathers could increase the risk of both their children and their grandchildren inheriting obesity, according to new research from University of Adelaide.

In laboratory studies, researchers from the University's Robinson Institute have found that molecular signals in the sperm of obese fathers can lead to obesity and diabetes-like symptoms in two generations of offspring, even though the offspring are eating healthily.

Cancer researchers discover how BRCA1 mutation starts breast, ovarian cancers

(TORONTO, Canada – July 15, 2013) – Scientists led by Drs. Mona Gauthier and Tak Mak at The Campbell Family Institute for Breast Cancer Research at the Princess Margaret Cancer Centre have solved a key piece in the puzzle of how BRCA1 gene mutations specifically predispose women to breast and ovarian cancers.

Drug shows dramatic reduction in seizures in patients with tuberous sclerosis complex

A drug originally developed to prevent the rejection of transplanted organs has now been shown to dramatically reduce seizures in patients with tuberous sclerosis complex (TSC) – a genetic disease characterized by benign tumors on multiple organ systems. TSC is estimated to affect more than a million individuals throughout the world.

The study is the latest to demonstrate the effectiveness of everolimus for TSC patients. Previous studies conducted at Cincinnati Children's Hospital Medical Center showed that everolimus reduced tumors in the brain and the kidney.

Researchers discover new retroviruses in polar bear Knut and panda Bao Bao

Following the death of the polar bear Knut at Berlin Zoo, examinations carried out at the Leibniz Institute for Zoo and Wildlife Research in Berlin showed that Knut was suffering from virus-induced encephalitis (acute inflammation of the brain).

Researchers at Saarland University and IZW have now analyzed his genetic material and discovered and characterized new sequences of endogenous retroviruses. The retroviruses were also found in another former resident of Berlin Zoo: the giant panda Bao Bao.

Scientists at NCI generate largest data set of cancer-related genetic variations

PHILADELPHIA — Scientists at the National Cancer Institute (NCI) have generated a data set of cancer-specific genetic variations and are making these data available to the research community, according to a study published in Cancer Research, a journal of the American Association for Cancer Research.

This will help cancer researchers better understand drug response and resistance to cancer treatments.

Is workplace flexibility failing to give parents time with their children?

Parents are increasingly experiencing a 'time squeeze' as they struggle to navigate the pressures of full-time employment and the demands of caring for their children. Research in the Journal of Marriage and Family examines if flexible working schemes are helping or adding to this pressure.

The authors examined how the introduction of ROWE (Results Only Work Environment) has impacted parents' perceptions of their time. Under this scheme employees are paid for results, rather than their time.

Very preterm babies show bonding difficulties despite parental sensitivity

A new study suggests that some very preterm babies have trouble bonding with their care-givers due to neurological impairments and not to the way their parents interact with them.

University of Warwick researchers found that most very preterm and very low birthweight (VP/VLBW) infants were securely attached to their parents.

But they also found that VP/VLBW infants were at higher risk for what is termed 'disorganised attachment' – when a child shows conflicting behaviour in their relationship with their parents.
