Immune System to Fight Brain Tumors

May 30, 2013 4:41 pm | by Lund University | Comments

Research at Lund University in Sweden gives hope that one of the most serious types of brain tumor, glioblastoma multiforme, could be fought by the patients' own immune system. The tumors are difficult to remove with surgery because the tumor cells grow into the surrounding healthy brain tissue. A patient with the disease therefore does not usually survive much longer than a year after the discovery of the tumor.

New Gene Delivery Method: Magnetic Nanoparticles

May 30, 2013 4:40 pm | by Federation of American Societies for Experimental Biology | Comments

Stent angioplasty saves lives, but there often are side effects and complications related to the procedure, such as arterial restenosis and thrombosis. In the June 2013 issue of The FASEB Journal, however, scientists report that they have discovered a new nanoparticle gene delivery method that may overcome current limitations of gene therapy vectors and prevent complications associated with the stenting procedure.

Omega-3 Fatty Acids May Help Heal a Broken Heart

May 30, 2013 4:37 pm | by Federation of American Societies for Experimental Biology | Comments

Procedures like angioplasty, stenting and bypass surgery may save lives, but they also cause excessive inflammation and scarring, which ultimately can lead to permanent disability and even death. A new research report appearing in The FASEB Journal, shows that naturally derived compounds from polyunsaturated fatty acids (omega-3s) may reduce the inflammation associated with these procedures to help arteries more fully and completely heal.

Columbia Nursing Study Finds Women Less at Risk than Men for Healthcare Associated Infections

May 30, 2013 4:35 pm | by Columbia University Medical Center | Comments

A new study from Columbia University School of Nursing supports a growing body of evidence that women are less likely to contract bloodstream or surgical site infections than their male counterparts. Researchers investigated the incidence of infection in thousands of hospitalized patients and found the odds for women succumbing to a bloodstream infection (BSI) and surgical-site infection (SSI) were significantly lower than for men.

Johns Hopkins Surgeons Among First in the Country to Perform a Robotic Single-Site Hysterectomy

May 30, 2013 4:33 pm | by Johns Hopkins Medicine | Comments

Two Johns Hopkins gynecologic surgeons are among the first in the nation to perform a robotic hysterectomy using a single, small incision. Amanda Nickles Fader, M.D. and Stacey Scheib, M.D. recently performed several other types of single-site robotic gynecologic procedures—including surgery for fibroids, abnormal uterine bleeding, and ovarian cysts and masses.

Researchers Identify Novel Approach to Create Red Blood Cells, Platelets In Vitro

May 30, 2013 4:29 pm | by Boston University Medical Center | Comments

A study led by Boston University School of Medicine has identified a novel approach to create an unlimited number of human red blood cells and platelets in vitro. In collaboration with Boston University School of Public Health (BUSPH) and Boston Medical Center (BMC), the researchers differentiated induced pluripotent stem (iPS) cells into these cell types, which are typically obtained through blood donations.

Biologists Take Snapshot of Fleeting Protein Process

May 30, 2013 4:25 pm | by Rice University | Comments

Structural biologists from Rice University and Baylor College of Medicine (BCM) have captured the first three-dimensional crystalline snapshot of a critical but fleeting process that takes place thousands of times per second in each human cell. The research appears online today in the journal Cell Reports and could prove useful in the study of cancer and other diseases.

Worldwide Lecture Tour Touts Point-of-Care Healthcare

May 30, 2013 4:19 pm | by New Jersey Institute of Technology | Comments

NJIT Distinguished Professor and electrical engineer Atam Dhawan hits the lecture trail again this summer as a distinguished speaker for an IEEE life sciences lecture series. His focus will be how "Point of Care Healthcare" can reduce illness, improve the quality of life, and stop spiraling healthcare costs. Dhawan, who will stop at conferences in Japan, Colombia and Croatia, tells audiences about the following.

A New Kind of Chemical ‘Glue’

May 30, 2013 11:20 am | by David L. Chandler, MIT News Office | Comments

Over the past three decades, researchers have found various applications of a method for attaching molecules to gold; the approach uses chemicals called thiols to bind the materials together. But while this technique has led to useful devices for electronics, sensing and nanotechnology, it has limitations. Now, an MIT team has found a new material that could overcome many of these limitations.

Decontaminating Patients Cuts Hospital Infections

May 30, 2013 10:54 am | by Lindsey Tanner, AP Medical Writer | Comments

Infections in U.S. hospitals kill tens of thousands of people each year, and many institutions fight back by screening new patients to see if they carry a dangerous germ, and isolating those who do. But a big study suggests a far more effective approach: Decontaminating every patient in intensive care.
