Technology Better Than Tape Measure for Identifying Lymphedema Risk

Vanderbilt University Medical Center

Bioimpedance spectroscopy (BIS) is better than a tape measure for assessing a woman’s risk for developing lymphedema, painful swelling in the arm after breast cancer surgery.

Adaptive Cruise Control Vehicles Create Phantom Traffic Jams in Road Test

Vanderbilt University

Work and his collaborators tested seven different cars from two manufacturers on a remote, rural roadway in Arizona. They simulated various driving conditions with a pace car changing its speed, followed by a vehicle using adaptive cruise control. The team measured how quickly and aggressively the ACC system responded to the pace car speed changes.

Key Step in Transformation of B Cells to Antibody-Secreting Cells Described

University of Alabama at Birmingham

Researchers have detailed the role of a key controlling factor in the transformation of B cells into antibody-secreting cells, cells that make antibodies to fight invading pathogens like viruses. The factor also is needed for memory B cells to respond to a second, subsequent infection by a pathogen.

Stem Cells Make More ‘Cargo’ Packets to Carry Cellular Aging Therapies

Johns Hopkins Medicine

Johns Hopkins scientists report that adult cells reprogrammed to become primitive stem cells, called induced pluripotent stem cells (iPSCs), make tiny “cargo packets” able to deliver potentially restorative or repairing proteins, antibodies or other therapies to aged cells. They say the human iPSCs they studied produced much more of the packets, formally known as extracellular vesicles, than other kinds of adult stem cells commonly used for this purpose in research.

Tumor Mutations May Predict Response to Immunotherapy

Johns Hopkins Medicine

Checkpoint inhibitor drugs that stimulate the immune system have become a growing success story in the treatment of some cancers. But about half of patients whose tumors are marked by a large number of mutations from so-called mismatch repair genetic deficiency fail to respond to the drugs.

‘Google Maps’ for Cancer: Image-Based Computer Model Reveals Finer Details of Tumor Blood Flow Behavior

Johns Hopkins Medicine

Johns Hopkins Medicine researchers say they have developed something akin to a “Google Maps” approach for more accurately computing and visualizing the structural and functional blood vessel changes needed for tumor growth. By pairing high-quality 3D imaging data of tumor specimens from animal models with sophisticated mathematical formulas, the researchers say they now have a model that accurately represents blood traffic inside tumors, including the complex blood flow, oxygenation and structural changes that occur.
