Not exact matches

In experiments conducted on human lung endothelial cells and in mice, the researchers showed that NS1 caused permeability of the endothelium, which lines the walls of blood and lymph vessels.

In the AlloSphere, it's as if Marth's researchers are standing inside blood vessels, visualizing data on a human scale that is normally too small to see.

Niklason hopes that other simple engineered tissues, such as the blood vessels she has been working on, will be ready for human trials within a year.

In a previous related study published in the Journal of Materials Science: Materials in Medicine, the same team of NTU scientists found that fish scale - derived collagen would induce human umbilical vein endothelial cells to express 2.5 times more of a specific type of collagen responsible for blood vessel formation, as compared to endothelial cells cultured on bovine collagen.

Yet, in humans, nowhere else on the body are there so many blood vessels so close to the surface of the skin than our faces.

They've even injected white blood cells into the vessels and watched as they squeezed through gaps in the vessel wall to reach the tissue on the other side, just as they do in the human body.

We will continue to investigate how it guides blood vessel growth, with the ultimate aim of tapping on its potential as a target to address human cardiovascular diseases.»

The epithelium's maturation into a villus intestinal epithelium with long finger - like extensions was helped along by co-culturing human intestinal microvascular endothelial cells on the opposite side of the shared matrix - coated porous membrane in the «vascular» channel where they assembled a surrogate blood vessel with a hollow lumen through which feeding medium was flowed.

On - demand replacement body parts inched closer to reality with the announcement from San Diego biotech company Organovo that its organ «printer» had created the first artificial blood vessel made entirely from human cells, with no synthetic scaffolding.

In an effort to overcome these limitations, a team at the Wyss Institute for Biologically Inspired Engineering led by its Founding Director, Donald Ingber, M.D., Ph.D., had previously engineered a microfluidic «Organ - on - a-Chip» (Organ Chip) culture device in which cells from a human intestinal cell line originally isolated from a tumor were cultured in one of two parallel running channels, separated by a porous matrix - coated membrane from human blood vessel - derived endothelial cells in the adjacent channel.

To study this barrier and determine why a lack of blood flow causes it to leak, the researchers built a blood - vessel - on - a-chip model consisting of a channel lined with a layer of human endothelial cells surrounded by extracellular matrix within a microfluidic device, which allowed them to easily simulate and control the flow of blood through a vessel and evaluate the cells» responses.

In cultured human cells and in rabbits with implanted stents, Finn and colleagues showed that metformin augmented the effect of mTOR inhibitors on regrowth of the blood vessel lining.

The most potent of these, known as effector memory T cells, are activated by a group of proteins known as human leukocyte antigens (HLAs) on the surface of endothelial cells lining the donated organ's blood vessels.

The vessel formed on the chip includes a channel lined by human endothelial cells and perfused with human whole blood.

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

While working at the Institute in 1959, the biochemist and expert in human nutrition David Kritchevsky, Ph.D., published the influential textbook Cholesterol, which explored his studies on the mechanisms of atherosclerosis, or fat deposits in blood vessels, and the role of cholesterol deposits in cardiovascular disease.

According to the U.S. Department of Health and Human Services, «High blood glucose levels over time can lead to increased deposits of fatty materials on the insides of the blood vessel walls.

Cardiovascular pharmacology: This branch of pharmacology deals with the study of the effects of drugs on the human's cardiovascular system, including the heart and blood vessels.

He is a specialist in Interventional Radiology, which uses imaging to deliver catheters, stents, and the like into tubular structures such as blood vessels, the urinary system, and the respiratory system; these methods were previously used on humans, but Dr. Weisse is developing them for pets.
