Handheld near-infrared imaging device enables quick detection of hematomas

When accidents that involve traumatic brain injuries occur, a speedy diagnosis followed by the proper treatment can mean the difference between life and death. A research team, led by Jason D. Riley in the Section on Analytical and Functional Biophotonics at the U.S. National Institutes of Health, has created a handheld device capable of quickly detecting brain injuries such as hematomas, which occur when blood vessels become damaged and blood seeps out into surrounding tissues where it can cause significant and dangerous swelling.

EETs may also drive growth and spread of cancer

A group of small molecules called EETs - currently under scrutiny as possible treatment targets for a host of cardiovascular diseases - may also drive the growth and spread of cancer, according to researchers at the Dana-Farber/Children's Hospital Cancer Center (DF/CHCC) and other institutions.

Blocking EETs may represent novel strategy for cancer therapy

Recent findings in mice suggest that blocking the production of small molecules produced in the body, known as epoxyeicosatrienoic acids (EETs), may represent a novel strategy for treating cancer by eliminating the blood vessels that feed cancer tumors.

New procedure helps reconstruct cricoid cartilage in a cancer patient

When Sherry Wittenberg was diagnosed with a rare cancer in the cricoid cartilage of her larynx, doctors told her the only way to treat the condition was to remove her voice box. The operation would leave her unable to speak normally and would require her to breathe through a hole in her neck for the rest of her life.

Microvascular stamp stimulates, directs blood vessel growth on wound surface

Researchers have developed a bandage that stimulates and directs blood vessel growth on the surface of a wound. The bandage, called a "microvascular stamp," contains living cells that deliver growth factors to damaged tissues in a defined pattern. After a week, the pattern of the stamp "is written in blood vessels," the researchers report.

F. nucleatum alters endothelial integrity and allows other bacteria to invade human body

A common oral bacteria, Fusobacterium nucleatum, acts like a key to open a door in human blood vessels and leads the way for it and other bacteria like Escherichia coli to invade the body through the blood and make people sick, according to dental researchers at Case Western Reserve University.
