Rochester scientists identify stem cells capable of skull formation, craniofacial bone repair in mice

A team of Rochester scientists has, for the first time, identified and isolated a stem cell population capable of skull formation and craniofacial bone repair in mice--achieving an important step toward using stem cells for bone reconstruction of the face and head in the future, according to a new paper in Nature Communications.

Researchers show how bacterial colony protects itself against toxic substances

Bacterial populations move over surfaces in coordinated way known as swarming, which allows them to spread further over organs and tissues and increases the virulence of the infection. This movement is driven by the action of the flagella and the chemoreceptors, the systems responsible for identifying chemical compounds in the environment and which are anchored at the poles of their cells, forming highly organised structures, of which the protein CheW forms part.

New technology could help identify, characterize biologically active molecules produced by living cells

Gene sequencing company Illumina recently made big waves by announcing a new spinoff, Grail, dedicated to building a test for cancer by sequencing tumor DNA fragments found in blood. The company also reported plans for a separate project to identify single cells and tag them for later analysis.

New UEA-led research initiative aims to improve understanding of deictic communication in humans

A major new €3.5 million research initiative led by the University of East Anglia will aim to improve understanding of a fundamental part of communication in humans.

Researchers link symptoms of schizophrenia with the brain's anatomical characteristics

An international team, made up of researchers from the University of Granada, Washington University in St. Louis, and the University of South Florida, has linked the symptoms of schizophrenia with the anatomical characteristics of the brain, by employing magnetic resonance imaging (MRI).

New brain study affirms truth in age old theory 'practice makes perfect'

'Practice makes perfect' may be a cliché but a new brain study out of York U affirms this age old theory. In this study, Faculty of Health researchers were looking at fMRI brain scans of professional ballet dancers to measure the long-term effects of learning.

Newcastle University scientists use seaweed extract to develop 'Stem-gell' bandage for wound healing

Publishing in STEM CELLS Translational Medicine Professor Che Connon and Dr Stephen Swioklo describe the low-cost seaweed solution.

Research offers novel insights into root causes of schizophrenia

Schizophrenia is a mysterious and devastating disorder that afflicts one percent of the adult population worldwide. Its symptoms — hallucinations, emotional withdrawal, and cognitive impairment — are chronic and typically emerge just as individuals are entering adulthood. Today's medications treat just one of these symptoms (psychosis); treatments for the underlying disease and its many other symptoms have been hard to develop, because no one really understands what causes the disorder.

Bile acid enables foetus to produce blood stem cells

A research group at Lund University in Sweden has been able to show that bile acid is transferred from the mother to the foetus via the placenta to enable the foetus to produce blood stem cells.

Framework for improving chemical hazard assessment without animals

A new paper published in Regulatory Toxicology and Pharmacology, co-authored by the Physicians Committee for Responsible Medicine, calls for ongoing development and regulatory acceptance of adverse outcome pathways (AOPs), a framework for improving chemical hazard assessment by prioritizing modern test methods that reduce animal use.

Study provides vital information about mechanisms governing DNA repair

DNA damage can lead to gene inactivation or deregulation and cause various diseases such as cancer; however, many DNA repair mechanisms allow cells to survive against such damage. A study lead by Antoine Simoneau of the laboratory of Dr. Hugo Wurtele, a researcher in immunology-oncology at the Maisonneuve-Rosemont Hospital (CIUSS de l'Est-de-l'Île-de-Montréal) and professor at the Faculty of Medicine, University of Montreal, and recently published in the prestigious journal Nucleic Acids Research, provides valuable information about certain mechanisms governing DNA repair.

HIV protein alters activity of networked neurons

Nearly half of HIV infected patients suffer from impaired neurocognitive function. The HIV protein transactivator of transcription (Tat) is an important contributor to HIV neuropathogenesis because it is a potent neurotoxin that continues to be produced despite treatment with antiretroviral therapy.

New partnership aims to study underlying neurobiology and genetics of PTSD, TBI

Cohen Veterans Bioscience today announced two new collaborative partnership efforts that will provide critical research tools for understanding the underlying neurobiology and genetics of post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI) with the goal of accelerating the development of first generation diagnostics and treatments.

Graphene-based electrodes could be safely implanted in the brain

Researchers have successfully demonstrated how it is possible to interface graphene - a two-dimensional form of carbon - with neurons, or nerve cells, while maintaining the integrity of these vital cells. The work may be used to build graphene-based electrodes that can safely be implanted in the brain, offering promise for the restoration of sensory functions for amputee or paralysed patients, or for individuals with motor disorders such as epilepsy or Parkinson's disease.

Human brain uses several frequency channels for communication

In the brain, the visual cortex processes visual information and passes it from lower to higher areas of the brain. However, information also flows in the opposite direction, e.g. to direct attention to particular stimuli. But how does the brain know which path the information should take? Researchers at the Ernst Strüngmann Institute for Neuroscience in Frankfurt in Cooperation with Max Planck Society have now demonstrated that the visual cortex of human subjects uses different frequency channels depending on the direction in which information is being transported.

Applying ultrasound therapies for recovery of cardiac stem cells

A joint project of researchers from Universidad Politécnica de Madrid (UPM), Julius Wolff Institute and led by Spanish National Center for Cardiovascular Research shows that when cardiac stem cells undergo low-intensity pulsed ultrasound treatment, these cells can perform continuing modifications, tissue remodeling and regeneration of damaged cardiac tissue after a heart attack.

Research points to potential use of radiotherapy in treating systemic cancer

An international team of researchers lead by the University of Granada has proven that mesenchymal stem cells (MSC) may be used as enhancer agents of local and systemic effects of radiotherapy, that is to say, those which affect the irradiated tumour and tumour cells located at a certain distance of the irradiated ones.

Mild reduction in food intake slows development of autosomal-dominant polycystic kidney disease

A small reduction in food intake—less than required to cause weight loss—dramatically slowed the development of a common genetic disorder called autosomal-dominant polycystic kidney disease (ADPKD) in mice, a new study in American Journal of Physiology—Renal Physiology reports.

FDA-approved blood pressure drug reduces cell damage linked to Alzheimer's disease

In laboratory neuronal cultures, an FDA-approved drug used to treat high blood pressure reduced cell damage often linked to Alzheimer's disease, say researchers at Georgetown University Medical Center and the National Institutes of Health.
