Researchers at Linköping University are now launching a plan to effectively treat psoriasis. About 300 000 Swedes suffer from the difficult to treat disease, which manifests itself in scaly and often itchy patches on the skin. The reason is that cells divide without restraint as new blood vessels form in the deeper layers of the skin. An important component is the psoriasin protein (S100A7), which are abundant in psoriasis-affected skin but rarely in normal skin. The same...

(Ivanhoe Newswire) — Scientists have discovered a new way to target cancer through manipulating a master switch responsible for cancer cell growth. Cancer cells can grow and multiply faster by creating their own blood vessels. Cancer cells gain the nutrients they need by producing proteins that make blood vessels grow, helping deliver oxygen and sugars to the tumor. These proteins are vascular growth factors like VEGF – the target for the anti-cancer drug Avastin. Making these...

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. A paper describing the new approach will appear as the January 2012 cover article of the journal Advanced Materials. "Any kind of tissue you want to...

Scientists at the University of North Carolina at Chapel Hill School of Medicine have identified a cellular protein that plays a central role in the formation of new blood vessels. The molecule is the protein Shc (pronounced SHIK), and new blood vessel formation, or angiogenesis, is seriously impaired without it. The study, which appeared online November 16, 2011 in the journal Blood, was led by associate professor of cell and molecular physiology at UNC, Ellie Tzima, PhD, who is also a...

Image 1 - Diet Key To Becoming A Queen Bee

A honey bee becomes a royal queen or a common worker as a result of the food she receives as a larva. While it has been well established that royal jelly is the diet that makes bees queens, the molecular path from food to queen is still in dispute. However, scientists at Arizona State University, led by Adam Dolezal and Gro Amdam, have helped reconcile some of the conflicts about bee development and the role of insulin pathways and partner proteins. Their article "IIS and TOR...

By manipulating a well-known molecular pathway, JDRF-funded scientists breathe new life into aging beta cells As a person ages, the ability of their beta cells to divide and make new beta cells declines. By the time children reach the age of 10 to 12 years, the ability of their insulin-producing cells to replicate greatly diminishes. If these cells, called beta cells, are destroyed–as they are in type 1 diabetes–treatment with the hormone insulin becomes essential to regulate...

Ever since scientists first began growing human cells in lab dishes in 1952, they have focused on improving the chemical soup that feeds the cells and helps regulate their growth. But surfaces also matter, says Laura Kiessling, a professor of chemistry at the University of Wisconsin-Madison, who observes that living cells are normally in contact with each other and with a structure called the extracellular matrix, not just with the dissolved chemicals in their surroundings. "Soluble...

In a new study published in the August 16th issue of Developmental Cell, researchers at NYU Langone Medical Center identified a molecular mechanism that guarantees that new blood vessels form in the right place and with the proper abundance. "We have known for a long time that blood vessels branch to give rise to new ones and that in some places of our bodies this branching occurs with a reproducible pattern. However, the mechanisms that ensure that new vessels sprout at specific locations...

Nanostructure promotes growth of new blood vessels, mimics natural protein Tissue deprived of oxygen (ischemia) is a serious health condition that can lead to damaged heart tissue following a heart attack and, in the case of peripheral arterial disease in limbs, amputation, particularly in diabetic patients. Northwestern University researchers have developed a novel nanostructure that promotes the growth of new blood vessels and shows promise as a therapy for conditions where increased blood...

ambsace
  • Bad luck; misfortune.
  • The smallest amount possible or the most worthless thing.
The word 'ambsace' comes from a Latin word meaning 'both'.
