Two new optical devices could reduce the need to take tissue samples during medical examinations and operations and to then send them for testing – potentially speeding up diagnosis and treatment and cutting healthcare costs.
Accurate diagnosis of Parkinson's disease, and the related disease "dementia with Lewy bodies," can be difficult in the early stages of both conditions. While brain biopsies can be more accurate, the risk of complications has been considered too high.
MedUni Vienna researchers have published the results of a clarifying research study on the potential transmissibility of Alzheimer’s disease. Although the protein associated with Alzheimer’s disease, amyloid-β, might be transmissible under very unusual circumstances, this does not go along with a transmission of the clinical manifestation of Alzheimer’s disease. The affected persons…
Scientists have many tools at their disposal for looking at preserved tissue under a microscope in incredible detail, or peering into the living body at lower resolution. What they haven't had is a way to do both: create a three-dimensional real-time image of individual cells or even molecules in a living animal.
A novel technique to use the body’s natural sodium (salt) content to provide a more detailed picture of tissue health and disease is to be pioneered by MRI experts at The University of Nottingham.
Bioengineers and physicians at the University of California, San Diego have developed a potential new therapy for critical limb ischemia, a condition that causes extremely poor circulation in the limbs and leads to an estimated 230,000 amputations every year in North America and Europe alone to prevent the spread of infection and tissue death. The new therapy could prevent or limit amputations…
A pioneer in cone beam computed tomography (CBCT) imaging, NewTom recently introduced the only CBCT system with an open gantry and supine positioning, which the firm reports is ‘…ideal for a host of diagnostic needs. Exceeding the limits posed by CT systems, the NewTom 5G XL combines high diagnostic resolution with minimum patient exposure.’
In an effort to develop a method for cartilage tissue engineering, researchers at Umeå University in Sweden successfully used cartilage cells from cow knee joints. By creating a successful method with conditions conducive to growing healthy cartilage tissue, the findings could help lead to a new treatment cure for osteoarthritis using stem cell-based tissue engineering. This is according to a…
Surgeons removing a malignant brain tumor don't want to leave cancerous material behind. But they're also trying to protect healthy brain matter and minimize neurological harm.
Fibrocartilage tissue in the knee is comprised of a more varied molecular structure than researchers previously appreciated, according to a new study by researchers from the Perelman School of Medicine at the University of Pennsylvania and the University of Delaware.
Doctors at the Duke University School of Medicine have tested a new injectable agent that causes cancer cells in a tumor to fluoresce, potentially increasing a surgeon’s ability to locate and remove all of a cancerous tumor on the first attempt. The imaging technology was developed through collaboration with scientists at Duke, the Massachusetts Institute of Technology (MIT) and Lumicell Inc.
Antibodies combat viruses and bacteria. They also attach themselves to cancer cells – in a typical, characteristic way. Fraunhofer scientists are using this property to detect cancer cells in tissue samples. Such rapid tests can already be applied by surgeons during operations – within a few minutes and without expensive equipment.
The European Tissue Symposium (ETS) has launched a brand new website, which offers a one-stop-shop for information and sound science. It will prove invaluable for anyone looking for details on the most hygienic way to dry hands following a visit to the washroom.
In the field of cancer diagnostics often tissue has to be cut in small pieces to fit on standard slides, although larger tissue sizes would be advantageous for diagnosis.In addition, most high throughput scanners available on the market are only able to scan normal sized slides. Some single slide scanners are able to process double sized slides but there is no system available for the automated…
Researchers funded by the National Institute of Biomedical Imaging and Bioengineering at Tufts University and their collaborators have successfully developed a 3-dimensional (3D) tissue-engineered model of bone marrow that can produce functional human platelets outside the body (ex vivo).
In a small pilot study, researchers from North Carolina State University have demonstrated a rapid, simple way to generate large numbers of lung stem cells for use in disease treatment. This method of harvesting and growing a patient’s own lung stem cells shows promise in mice for treating idiopathic pulmonary fibrosis (IPF), and could one day provide human IPF sufferers with an effective, less…
Biotronik, manufacturer of MR conditional cardiac devices, has announced CE approval for full-body MRI scanning for its last two generations of ProMRI cardiac resynchronization therapy defibrillator* (CRT-Ds) systems.
Chemists at Caltech have developed a new sensitive technique capable of detecting colorectal cancer in tissue samples—a method that could one day be used in clinical settings for the early diagnosis of colorectal cancer.
A team of Tel Aviv University and Harvard Medical School researchers has devised a non-invasive technique that harnesses pulsed electric fields to generate new skin tissue growth. According to their research, the novel non-invasive tissue stimulation technique, utilizing microsecond-pulsed, high-voltage, non-thermal electric fields, produces scarless skin rejuvenation and may revolutionize the…
Genetically engineered fibers of the protein spidroin, which is the construction material for spider webs, has proven to be a perfect substrate for cultivating heart tissue cells, MIPT researchers found. They discuss their findings in an article that has recently come out in the journal PLOS ONE.
A multi-year study led by researchers from the Simons Center for Data Analysis (SCDA) and major universities and medical schools has broken substantial new ground, establishing how genes work together within 144 different human tissues and cell types in carrying out those tissues' functions.
Women may have a more difficult time than men in recovering from concussion, according to a new study published online in the journal Radiology.
Each year, approximately 1.6 million women in the USA have breast biopsies to diagnose or rule out cancer. Pathological diagnosis is considered the gold standard – how accurate are these diagnoses? Report: Cynthia E. Keen
Regenerative medicine uses cells harvested from the patient’s own body to heal damaged tissue. Fraunhofer researchers have developed a cell-free substrate containing proteins to which autologous cells bind and grow only after implantation.
Damage to the spinal cord rarely heals because the injured nerve cells fail to regenerate. The regrowth of their long nerve fibers is hindered by scar tissue and molecular processes inside the nerves. An international team of researchers led by DZNE scientists in Bonn now reports in Science that help might be on the way from an unexpected quarter: in animal studies, the cancer drug epothilone…
