Researcher develops new method to accurately identify elusive molecules

Among the most important molecules in the living world are sugars or carbohydrates, which play a vital role in life processes. Sugars provide the main source of fuel for the body, protect muscles from damage and contribute to the immune response.

Sneezing elicits blinking response to protect the body from germs, says allergist

The changing weather brings about many things: holiday excitement, a different wardrobe and—perhaps most annoyingly—cold and flu season.

MUSC researchers harness cutting-edge technology to uncover new role for pericytes during stroke

Pericytes are the primary locus of matrix-mellaproteinase-9-dependent (MMP-9) capillary damage and blood leakage during ischemia, according to preclinical findings reported by Medical University of South Carolina investigators in an article published online on November 14, 2016 by The Journal of Neuroscience.

Experts use MRI scans to investigate heart function of kidney patients during dialysis treatment

Experts in magnetic resonance imaging (MRI) and kidney disease have carried out the first ever scans to study the heart function of kidney patients while they are having dialysis treatment.

HSCI researchers use color tagging system to track development of blood stem cells

Harvard Stem Cell Institute (HSCI) researchers have used a colorful, cell-labeling technique to track the development of the blood system and trace the lineage of adult blood cells travelling through the vast networks of veins, arteries, and capillaries back to their parent stem cell in the marrow.

Dietary supplement extracted from Amaranthus can increase plasma nitrate, study shows

A new, clinical study confirms that dietary supplementation of nitrate from a natural extract of Amaranthus species nicknamed "red spinach," results in a significant increase in plasma nitrite that ultimately enhances nitric oxide.

UNC scientists find clue that may help explain why people differ in ability to survive arterial blockages

Researchers at the University of North Carolina School of Medicine have found a major clue that may explain why some people sustain relatively little damage from strokes or heart attacks despite severe arterial blockages.

Improved skin graft process shows promise for treating severe burn wounds

Full thickness skin grafts are the golden standard for treating burn wounds. But most skin grafts for severe burns require a donor, and for large or complicated injury sites, a full thickness skin graft is hard to come by.

UC3M scientists use mathematical description to explain how tumors induce growth of blood vessels

Universidad Carlos III de Madrid has carried out a study that mathematically explains how tumors induce the growth of blood vessels. The study maintains that the tips of the blood vessels expand like a soliton, a solitary wave similar to a tsunami.

Mount Sinai researchers use OCT angiography to identify early stages of glaucoma

In a first of its kind study, Mount Sinai researchers are using optimal coherence tomography (OCT) angiography to look at the earliest stages of glaucoma and identify characteristic patterns of different forms of glaucoma based on their vascular patterns.

Discovery of neuropilin 2 deficiency may lead to new therapies for edema and lymphedema

Fluid accumulation and swelling (edema) may result from the malfunctioning of regulatory processes controlling vessel permeability in the body.

Good blood microcirculation linked to longevity

Human longevity has been previously linked by researchers to genetic factors, calorie restriction, and certain life-style factors such as physical activity or the Mediterranean diet.

LJI researchers reveal unanticipated way by which neutrophils defend against invading pathogens

As an arm of the innate immune system, white blood cells called neutrophils form the first line of defense against invading pathogens.

Experts develop new genomic testing method for pulmonary hypertension caused by genetic mutation

Pulmonology and genetics experts from two Utah healthcare organizations have collaboratively developed a new diagnostic genomic testing method for a rare form of pulmonary hypertension caused by a genetic mutation they discovered three years ago.

Scientists gain new insights into how cancer cells may squeeze through narrow blood vessels

The spread of cancer from a tumor's original location to other parts of the body can play a major role in whether the disease turns deadly. Many steps in this process, called metastasis, remain murky.

Structures on surface of pneumococci determine bacteria’s ability to cause meningitis

Structures on the surface of pneumococci determine the ability of these bacteria to enter the brain and cause severe infections, according to a paper published in The Journal of Clinical Investigation by researchers at Karolinska Institutet.

New computer model shows how spleen filters misshapen red blood cells

Researchers, led by Carnegie Mellon University President Subra Suresh and MIT Principal Research Scientist Ming Dao, have created a new computer model that shows how tiny slits in the spleen prevent old, diseased or misshapen red blood cells from re-entering the bloodstream.

Stroke can cause long-term damage to blood-spinal cord barrier, study finds

A team of researchers at the University of South Florida investigating the short and long-term effects of ischemic stroke in a rodent model has found that stroke can cause long-term damage to the blood-spinal cord barrier (BSCB), creating a "toxic environment" in the spinal cord that might leave stroke survivors susceptible to motor dysfunction and disease pathology.

Study reveals gpihbp1 gene could be novel target for treatment of muscular dystrophy

The average healthy man is 54 percent muscle by mass, but people with muscular dystrophy, an incurable, genetic condition, have almost no muscle at terminal stages of the disease.

New technique to grow blood vessels could accelerate growth of regenerative medicine

In addition the technique to grow the blood vessels in a 3D scaffold cuts down on the risk of transplant rejection because it uses cells from the patient. It was developed by researchers from the University of Bath's Department of Pharmacy and Pharmacology, working with colleagues at Bristol Heart Institute.
