Bioengineers and physician-scientists zap tumors with light-activated nanoparticles

Rice University bioengineers and physician-scientists at Baylor College of Medicine and Texas Children's Hospital have successfully destroyed tumors of human brain cancer cells in the first animal tests of a minimally invasive treatment that zaps glioma tumors with heat. The tests involved nanoshells, light-activated nanoparticles that are designed to destroy tumors with heat and avoid the unwanted side effects of drug and radiation therapies.

DSM supports Queensland Premier's 'Disaster Relief Appeal'

Significant flooding occurred in many areas of Queensland during late December 2010 and early January 2011. Thousands of residents were affected. A disaster relief appeal, the 'Premier's Disaster Relief Appeal', was launched on 29 December 2010, by Premier of Queensland, Anna Bligh. DSM recognizes the efforts of Queenslanders who pitched in to help their fellow citizens clean-up in the wake of the floods and help families in need, many of whom lost everything.

Rice, BCM discovery addresses key roadblock to growing replacement tissues, organs

Researchers from Rice University and Baylor College of Medicine (BCM) have broken one of the major roadblocks on the path to growing transplantable tissue in the lab: They've found a way to grow the blood vessels and capillaries needed to keep tissues alive.

Scientists introduce DNA directly into cell nucleus using protein nanodisks

One of the challenges of gene therapy - a set of methodologies aimed at treating several nucleic acid diseases - is to assure that this material arrives directly to the nucleus of the cell without losing a substantial amount along the way and without producing any undesired side effects. With this aim, scientists experiment with the use of different types of vectors, molecules capable of transporting genetic material to the correct place.

Researchers design new electronic technology equipment for detecting live cellular processes

The electronic technology equipment designed by the researchers- which is in patent process-is based on molecular imaging, a type of biomedical imaging capable of detecting live cellular processes. "These techniques differ from conventional medical imaging in that the information they show is function not form, which means that they are capable of showing the malfunctioning of an organ before the malfunction turns into an anatomical change", Juan Jos- Vaquero explained.

GT Life Sciences and BGI complete CHO-K1 genome sequencing

GT Life Sciences, a privately held biotechnology company that utilizes a proven metabolic modeling and experimental platform to drive the discovery and design of new products and processes for the life sciences field, and BGI, the largest genomics organization in the world, announced that they have successfully completed for the first time the sequencing of the Chinese hamster ovary genome.

MGH, Veridex establish research center of excellence on circulating tumor cell technologies

Massachusetts General Hospital (MGH) has entered into a collaborative agreement with Veridex LLC to establish a center of excellence in research on circulating tumor cell (CTC) technologies. The overall goal of the agreement is to develop and commercialize novel technologies for capturing and characterizing CTCs, solid tumor cells found at extremely low levels in the bloodstream, which may offer a key to noninvasive characterization of cancer and potentially to early detection.

SBUMC to unveil one-of-a-kind neuroendovascular simulator

Stony Brook University Medical Center will unveil this Friday a one-of-a-kind neuroendovascular simulator that recreates vasculature in the brain, including scenarios of damaged vessels from acute stroke, brain aneurysms, and other cerebrovascular anomalies. Affectionately known in the lab as "Headley".

Bioengineers explain why some neurons die sooner than others in brains of AD patients

Bioengineers from the University of California, San Diego developed an explanation for why some types of neurons die sooner than others in the brains of people with Alzheimer's disease. These insights, published in the journal Nature Biotechnology on November 21, come from detailed models of brain energy metabolism developed in the Department of Bioengineering at the UC San Diego Jacobs School of Engineering.

Researchers synthesize wound-healing peptides

Newly-created bioactive peptides promote wound healing through the growth of new blood vessels and epithelial tissue, such as skin. These wound-healing peptides, synthesized by researchers at the Tufts Center for Innovations in Wound Healing Research, increased angiogenesis in vitro by 200 percent.

Conference focuses on new molecular, mechanical solutions to improve surgeries

A two-day conference at the University of Chicago Medical Center is designed to offer surgeons a peek at the profession's future by focusing on new molecular and mechanical solutions to three age-old problems: preventing the breakdown of anastomoses (the surgically created connections between blood vessels), improving tissue healing after surgery and developing new tools to test and sharpen surgical skills.

Researchers develop medical model for regenerating bladders using stem cells

Researchers in the United States have developed a medical model for regenerating bladders using stem cells harvested from a patient's own bone marrow. The research, published in STEM CELLS, is especially relevant for paediatric patients suffering from abnormally developed bladders, but also represents another step towards new organ replacement therapies.
