Not exact matches

As they had hoped, a narrow ultrasound beam loosened the blood vessel walls in part of a mouse's brain.

After imaging defiant metastatic cells in the brains of mice, researchers noticed that the cells that were able to survive grew on top of blood capillaries, each cell sticking closely to its vessel «like a panda bear hugging a tree trunk,» Dr. Massagué says.

2 - D cell - culture and mouse experiments also provided key evidence of the virus's modus operandi; although the rodent brain doesn't harbor the full contingent of human neural stem cells, it has blood vessels and immune - system components that organoids lack.

In another study of mice injected with GDF11, postdoc Lida Katsimpardi and others in the lab of Harvard neuroscientist Lee Rubin found that GDF11 also encourages growth of new blood vessels and olfactory neurons in the mouse brain.

Johns Hopkins researchers, working with mice, say they have identified a chemical compound that reduces the risk of dangerous, potentially stroke - causing blood vessel spasms that often occur after the rupture of a bulging vessel in the brain.

When stimulated in one of these ways for five days or longer, the mice's brains had smaller, less - branched blood vessels.

In 2009, Steven Goldman of the University of Rochester Medical Center in New York and his colleagues reported that human astrocytes are bigger, and have about 10 times as many fingerlike projections that contact other brain cells and blood vessels, than those of mice.

This 3 - D image shows new blood vessels, in green, that grew in a mouse's brain after the animal received blood from a younger mouse.

The second Science study showed that GDF11 can help an elderly mouse brain grow new blood vessels and neurons.

Blood (red) flows through newly grown blood vessels in a human brain organoid (green) implanted in a living mBlood (red) flows through newly grown blood vessels in a human brain organoid (green) implanted in a living mblood vessels in a human brain organoid (green) implanted in a living mouse.

Bethesda, Md. (March 20, 2018)-- Minoxidil, a popular drug used on the scalp to treat hair loss, might improve blood flow to the brain, lower blood pressure and increase elasticity in the blood vessels if taken in an oral form, according to a new study in mice.

Imaging tests showed that vessel diameter and blood flow to the brain increased in the minoxidil - treated mice.

In mice, the drug minoxidil changes blood vessel structure, reducing vessel stiffness and increasing blood flow to the brain.

To find out whether an oral form of minoxidil can remodel the vessel's wall to reduce blood vessel stiffness and enhance blood flow to the brain, researchers studied the drug's effects in mice.

As a result, the mice had high blood pressure, increased blood vessel stiffness, and reduced blood flow to the brain.

Three recent experimental studies focused on low consumption / exposure.949596 In one study, 29 smokers each consumed a single cigarette, immediately after which they had a significant decrease in blood vessel output power and significant increase in blood vessel ageing level and remaining blood volume 25 minutes later, as markers of atherosclerosis.94 In another study, human coronary artery endothelial cells were exposed to the smoke equivalent to one cigarette, which led to activation of oxidant stress sensing transcription factor NFR2 and up - regulation of cytochrome p450, considered to have a role in the development of heart disease.95 These effects were not seen when heart cells were exposed to the vapour from one e - cigarette.95 A study exposed adult mice to low intensity tobacco smoke (two cigarettes) for one to two months and found adverse histopathological effects on brain cells.96
