Researchers take a step toward neuronal replacement therapy

A new study has revealed that immature neurons taken from healthy mouse embryos can repair damaged brain circuitry and partially normalize metabolism when transplanted into adult mice that have grown morbidly obese due to a genetic deficiency.

Carefully selected young, healthy neurons can repair brain circuitry

Neuron transplants have repaired brain circuitry and substantially normalized function in mice with a brain disorder, an advance indicating that key areas of the mammalian brain are more reparable than was widely believed.

Transplantation of tissue-engineered windpipe can benefit patients with tracheal cancer

Tracheal tumors can be surgically removed, but most are too large for the surgery to be successful by the time they are discovered. Therefore, new therapeutic options are needed. Even in patients with operable tumors, the proportion of complete tumor resection is less than 60%. This outcome would be greatly improved if a trachea substitute with similar anatomical, physiological and biomechanical properties of the patient's original trachea were available.

No variation in mortality by timing of operation

The timing of surgical procedures—afternoon versus morning or Friday versus Monday—doesn't affect the risk of death after surgery, concludes a study in the December issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society.

Combination of radiation treatment and LY2109761 can prevent glioblastoma

Glioblastoma is regarded as the most malignant form of brain tumor. In many cases, neurosurgeons are not able to remove such tumors completely because of the risk of destroying too much brain tissue in the process. Moreover, it is often impossible to identify all the fine extensions by which the tumor spreads into surrounding healthy tissue. To at least slow down the growth of tumor cells that have remained in the head, almost all glioblastoma patients are treated by radiotherapy after surgery.

Anesthesia drug shortages can have devastating impact on patient care

The United States is facing ongoing shortages of several critical anesthesia medications—shortages with potentially serious effects on patient care and safety, according to a special article in the December issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society.

Ways to reduce serious complications and deaths due to surgical procedures

Surgical procedures save and improve lives worldwide, but the figures on serious complications and deaths are high. PhD student Sindre Høyland sees ways of reducing these numbers.

A new era in low energy, low dose and low injected contrast imaging

Royal Philips Electronics today announced that Philips iDose4, the latest generation of Philips iterative reconstruction technique, has nearly 500 sales. While iDose4 only began shipping in March, its success validates the desire of radiologists to be able to both acquire and reconstruct images in less time, with improved image quality at low dose.

Imaging is about finding the most appropriate way to assess heart disease

"The idea is that we're using the most appropriate technology to address individual clinical questions rather than just focusing on one technique," explains EAE President Dr Luigi Badano, from the University of Padua, Italy.

Asymmetric prototypes for mitral valve replacement

The heart's valves, which guarantee the unidirectional flow of blood from one chamber to another, are asymmetrical. For example, the two flaps of the heart's mitral valve - which regulates blood flow between the left atrium and the left ventricle - vary in size by up to 70 percent.

Study evaluates safety and effectiveness of Diamondback device for heart attacks

Drilling through concrete to create an opening may sound more like construction than medicine, but the approach is similar to what researchers at Orlando Regional Medical Center (ORMC) are doing in a clinical trial to evaluate a device that breaks through hardened coronary arteries, in an effort to prevent heart attacks and relieve chest pain.
