Study provides new insights into breast cancer metastasis

It has long been thought that cancer metastasizes, or spreads, when a single cancer cell escapes from the original tumor, travels through the bloodstream and sets up shop in distant organs. However, a growing body of evidence suggests that these bad actors don't travel alone; instead they migrate through the body in cellular clusters, like gangs.

Block copolymer hydrogels facilitate cryoprotection of red blood cells and increase tissue engineering

Freezing of medical tissue and cells usually requires the addition of cryopreservatives, although the added compounds can have undesired effects in subsequent applications.

Biochemical compound demonstrates increasing potential for use in cancer imaging

In the paper, an international team reviewed studies conducted over the past 30 years on a particular tracer, called “18F-FLT,” and found that it has the potential to improve diagnostic imaging, and thus treatment, of some cancers.

Study shows several Envigo rat models susceptible to genital HSV-2 infection

A scientific collaboration between Envigo and the Department of Infectious Disease at the University of Gothenburg, Sweden has unveiled study findings into rat models and their susceptibility to intra-vaginal herpes simplex virus-2 (HSV-2) infection.

Researchers identify definitive genetic defect in angiocentric gliomas

Diagnosis and treatment decisions for a recently recognized type of children's brain tumor should be improved by the discovery of the genetic mechanism that causes it, say researchers who identified the unusual DNA abnormality in angiocentric gliomas.

Gender associated with risk of cardiovascular recurrence in adults

Sex (biological and physiological characteristics) differences are increasingly being studied to assess symptoms, risk factors and outcomes for various diseases. Now, a new pan-Canadian study led by a team from the Research Institute of the McGill University Health Centre, suggests that gender rather than sex is associated with the risk of recurrence of cardiovascular events in adults.

Radiation could increase responses to innovative immune-based therapeutic approaches to fight cancer

A team of Georgia State University researchers is fighting cancers using a combination of therapies and recently found ways that radiation could maximize responses to novel immune-based therapeutic approaches to fight cancer.

New study lays foundation for future gene replacement therapies to treat ALS patients

Scientists have demonstrated for the first time that it is possible to specifically modify gene expression in diseased upper motor neurons, brain cells that break down in ALS.

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.

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.
