Researchers achieve breakthrough in blood vessel engineering

When someone has a deadly disease or sustains a life-threatening injury, a transplant or graft of new tissue may be the best -- or only -- treatment option.

Improving blood vessel growth could help mitigate health problems arising from obesity

New research led by York University's Faculty of Health shows that inhibiting a protein within blood vessels stimulates new blood vessel growth, resulting in healthier fat tissue and lower blood sugar levels.

First modeling system developed for testing age-specific human immune responses to vaccines

A team of scientists at Boston Children's Hospital has developed the first modeling system for testing age-specific human immune responses to vaccines -- outside the body. The practical, cost-effective new platform, using all human components, is expected to accelerate and de-risk the development, assessment and selection of vaccines.

NEI investigators combine two imaging modalities to view the retina in unprecedented detail

By combining two imaging modalities--adaptive optics and angiography--investigators at the National Eye Institute can see live neurons, epithelial cells, and blood vessels deep in the eye's light-sensing retina.

Transgenic rat model may provide new insights into cerebral amyloid angiopathy

In a report in The American Journal of Pathology investigators describe the generation of a successful novel transgenic rat model that accumulates amyloid specifically in brain blood vessels and strongly mimics many of the associated detrimental changes that are observed in humans - a condition known as cerebral amyloid angiopathy, which is also commonly observed in Alzheimer disease.

Researchers develop new material that improves quality, durability of knee cartilage implants

Researchers of Valencia's Polytechnic University, the University of Notre Dame and the Technological University of Auckland, along with multinational company Zimmer, have developed a new material that improves the quality and durability of the articular cartilage implants used in knee operations.

Researchers propose new contactless method for measuring blood flow in the upper limbs

The research team from Russia proposed a new contactless method for measuring blood flow in the upper limbs. The method is based on video recording of the skin surface under green light measuring the absorption of red blood cells. This helps to see how effective the circulatory system and the blood flow regulation are.

Researchers develop unique, biofuel-powered sensor to prevent and diagnose diseases

Researchers at Washington State University have developed an implantable, biofuel-powered sensor that runs on sugar and can monitor a body's biological signals to detect, prevent and diagnose diseases.

Blood-brain barrier can be important biomarker for early diagnosis of Alzheimer's disease

USC scientists say Alzheimer's could be diagnosed earlier if scientists focus on an early warning within the brain's circulation system.

New fiber laser-based ultrasound sensor may have potential applications in medical diagnostics

By creating a new twist on fiber optic sensors, researchers in China have developed a smart, flexible photoacoustic imaging technique that may have potential applications in wearable devices, instrumentation and medical diagnostics.

Mouse study suggests new therapeutic approach to treat heart failure

A heart attack triggers an acute inflammatory response, followed by resolution of inflammation and wound healing. A severe heart attack, however, can cause chronic and sustained inflammation that leads to heart failure and death.

Study sheds light on how vaso-occlusive pain crises arise in sickle-cell disease

One of the most common complications of sickle-cell disease occurs when deformed red blood cells clump together, blocking tiny blood vessels and causing severe pain and swelling in the affected body parts.

Researchers design nanotubes that can align water molecules into a square rod

First, according to Rice University engineers, get a nanotube hole. Then insert water. If the nanotube is just the right width, the water molecules will align into a square rod.

New target for pneumonia seems to restore tight barriers and fluid clearance in the lungs

Severe pneumonia causes a buildup of fluid in the lungs that makes the basics of breathing and getting oxygen out to the body difficult to impossible.

Scientists discover new target to treat blood vessel damage in diabetes

In diabetes, both the tightly woven endothelial cells that line our blood vessels and the powerhouses that drive those cells start to come apart as early steps in the destruction of our vasculature.

Experts witness action of influenza infection in the lungs of living mice

In the 1966 novel, Fantastic Voyage, written by biochemist and author Isaac Asimov, a crew of people become miniaturized in order to travel through the body of a scientist and save him from a blood clot in his brain.

Study reveals new way to inhibit capillary leakage in sepsis

Leakage from the blood capillaries is a key mechanism leading to septic shock and multiorgan failure, which affect millions of patients annually worldwide. However, there is no effective way to inhibit the vessel leakiness. A new study by scientists at the University of Helsinki and Wihuri Research Institute demonstrates that vascular leakage can be inhibited by targeting vascular integrins.

Researchers develop portable monitor to detect dangerous drop in white blood cells

Researchers funded by the National Institute of Biomedical Imaging and Bioengineering have developed a portable, non-invasive monitor that can determine, in one minute and without drawing blood, whether chemotherapy patients have a reduced number of white blood cells that could lead to infections.

Gas embolotherapy holds great potential for treating cancer

Embolization -- the use of various techniques to cut off the blood vessels that feed tissue growth -- has gained traction over the past few decades to treat cancerous tumors.

Researchers find novel gene in red blood cells that may help limb regeneration in adult newts

Newts are the only four-legged vertebrates that can regenerate their body parts even as adults. When a newt loses a limb, a mass of cells, called a blastema, is generated at the stump, from which a new, fully functional limb is eventually regenerated.
