The age from when children can hop on one leg

Motor development in children under five years of age can now be tested reliably: Together with colleagues from Lausanne, researchers from the University Children's Hospital Zurich and the University of Zurich have determined normative data for different exercises such as hopping or running. This enables parents and experts to gage the motor skills of young children for the first time objectively and thus identify abnormalities at an early stage.

Scientists unveil secrets of important natural antibiotic

An international team of scientists has discovered how an important natural antibiotic called dermcidin, produced by our skin when we sweat, is a highly efficient tool to fight tuberculosis germs and other dangerous bugs.

Their results could contribute to the development of new antibiotics that control multi-resistant bacteria.

Scientists have uncovered the atomic structure of the compound, enabling them to pinpoint for the first time what makes dermcidin such an efficient weapon in the battle against dangerous bugs.

Cell therapy a little more concrete thanks to VIB research

Cell therapy is a promising alternative to tissue and organ transplantation for diseases that are caused by death or poor functioning of cells. Considering the ethical discussions surrounding human embryonic stem cells, a lot is expected of the so-called 'induced pluripotent stem cells' (iPS cells). However, before this technique can be applied effectively, a lot of research is required into the safety and efficacy of such iPS cells. VIB scientists associated to the UGent have developed a mouse model that can advance this research to the next step.

Antibacterial protein's molecular workings revealed

On the front lines of our defenses against bacteria is the protein calprotectin, which "starves" invading pathogens of metal nutrients.

Vanderbilt investigators now report new insights to the workings of calprotectin – including a detailed structural view of how it binds the metal manganese. Their findings, published online before print in the Proceedings of the National Academy of Sciences, could guide efforts to develop novel antibacterials that limit a microbe's access to metals.

Biomarker may identify neuroblastomas with sensitivity to BET bromodomain inhibitors

PHILADELPHIA — Neuroblastoma, the most common malignant tumor of early childhood, is frequently associated with the presence of MYCN amplification, a genetic biomarker associated with poor prognosis. Researchers have determined that tumors containing MYCN amplification are sensitive to a new class of drugs, BET bromodomain inhibitors.

The researchers made this discovery in a preclinical study, which was funded in part by a Stand Up To Cancer Innovative Research Grant and was published in Cancer Discovery, a journal of the American Association for Cancer Research.

EASL publishes first comprehensive literature review on the burden of liver disease in Europe

Brussels and Geneva, 20th February 2013 --- Major progress has been made in the past 30 years in the knowledge and management of liver disease, yet approximately 29 million Europeans still suffer from a chronic liver condition.

Omega-3s inhibit breast cancer tumor growth, study finds

A lifelong diet rich in omega-3 fatty acids can inhibit growth of breast cancer tumours by 30 per cent, according to new research from the University of Guelph.

The study, published recently in the Journal of Nutritional Biochemistry, is believed to be the first to provide unequivocal evidence that omega-3s reduce cancer risk.

"It's a significant finding," said David Ma, a professor in Guelph's Department of Human Health and Nutritional Sciences, and one of the study's authors.

Microbubbles improve myocardial remodelling after infarction

Scientists from the Bonn University Hospital successfully tested a method in mice allowing the morphological and functional sequelae of a myocardial infarction to be reduced. Tiny gas bubbles are made to oscillate within the heart via focused ultrasound - this improves microcirculation and decreases the size of the scar tissue. The results show that the mice, following myocardial infarction, have improved cardiac output as a result of this method, as compared to untreated animals. The study is now being presented in the professional journal PLOS ONE.

Inhaled betadine leads to rare complication

Philadelphia, Pa. (February 21, 2013) - A routine step in preparing for cleft palate surgery in a child led to an unusual—but not unprecedented—case of lung inflammation (pneumonitis), according to a report in the The Journal of Craniofacial Surgery. The journal, edited by Mutaz B.

Human heart development slower than other mammals

The walls of the human heart are a disorganised jumble of tissue until relatively late in pregnancy, despite having the shape of a fully functioning heart, according to a pioneering study.

Experts from the University of Sheffield's Medical School collaborated on research to create the first comprehensive model of human heart development using observations of living foetal hearts. The results showed surprising differences from existing animal models.

Common acne drug not associated with increased risk of IBD

(Vancouver – February 20, 2013) – Doctors should not be discouraged from prescribing isotretinoin to adolescents for inflammatory acne, according to a new study by Canadian and U.S. scientists showing the drug does not increase the risk of inflammatory bowel disease (IBD).

New bioengineered ears look and act like the real thing

NEW YORK (Feb. 20, 2013) -- Physicians at Weill Cornell Medical College and biomedical engineers at Cornell University have succeeded in building a facsimile of a living human ear that looks and acts like a natural ear. Researchers believe their bioengineering method will finally succeed in the long quest by scientists and physicians to provide normal looking "new" ears to thousands of children born with a congenital ear deformity.

Bees attracted to contrasting colors when looking for nectar

Flower colors that contrast with their background are more important to foraging bees than patterns of colored veins on pale flowers according to new research, by Heather Whitney from the University of Cambridge in the UK, and her colleagues. Their observation of how patterns of pigmentation on flower petals influence bumblebees' behavior suggests that color veins give clues to the location of the nectar. There is little to suggest, however, that bees have an innate preference for striped flowers.

Early life stress may take early toll on heart function

AUGUSTA, Ga. – Early life stress like that experienced by ill newborns appears to take an early toll of the heart, affecting its ability to relax and refill with oxygen-rich blood, researchers report.

Queen's study shows psychotropic drug dispensing increases on entry to care homes

A study by Queen's University Belfast has found that the dispensing of psychotropic drugs to older people in Northern Ireland increases on entry to care homes.

According to the study, due to be published in the Journal of the American Geriatrics Society, antipsychotic drug dispensing in older people more than doubled from 8.2 per cent before entry to care homes to 18.6 per cent after entering care.
