VEGF-D

Product name:VEGF-D

Type:
Other Biological Products

Product description:
VEGF-D(or FIGF) is a vascular endothelial growth factor that in humans is encoded by the FIGF gene.
The protein encoded by this gene is a member of the platelet-derived growth factor/vascular endothelial growth factor (PDGF/VEGF) family and is active in angiogenesis, lymphangiogenesis, and endothelial cell growth. This secreted protein undergoes a complex proteolytic maturation, generating multiple processed forms which bind and activate VEGFR-2 and VEGFR-3 receptors. This protein is structurally and functionally similar to vascular endothelial growth factor C.

Why is there death and cancer?


In human history have been the natural aging has been the presence of death, then we may assume that the natural aging death will be a very well-deserved things. But not like this, the current study did find some organisms (lower organisms) have the ability to eternal life. So, the question is, eternal life is the ability to evolve the ability death or senescence evolved come from?

From an evolutionary point of view we have to try to interpret what Darwin this issue. If eternal ability evolved, imagine what the meaning of existence of this ability, through what kind of selection pressure to make some creature has the ability to eternal life? I think for a long time, did not expect what selection pressure allows a species to adapt to the environment and the screening of individuals of the species have eternal life and the ability to reproduce it. So I made another hypothesis, not an innate ability of biological aging death, it may be the ability of an organism evolved under natural selection pressures gradually acquired are filtered out! The following is an open brain hole time, we have to analyze at roughly what kind of natural selection pressure screening out aging death this phenotype!

Darwin's theory of evolution is generally summarized as follows: overgrowth, survival competition (between the two species and within species), natural selection, survival of the fittest.

Be careful! Traumatic Brain Injury let you have been surrounded by bored

In 1990, James Danckert 18 years old, his brother Paul drove a car accident hit a tree, when Paul was from a pile of rubble came out when he sustained multiple injuries, including brain trauma.

Complete recovery is difficult. Paul used to be a drummer, but when his wrist completely healed, drums no longer make him happy. Danckert remember, my brother again and again, bitterly complained that he felt very bored. "He is no sign of boredom. Even the things he once loved, he felt frustrated and dissatisfied, that was very boring." Danckert said.

A few years later, Danckert became a clinical neuropsychologist, he worked in contact with 20 young patients who have been suffering the trauma of the brain. Think of his own brother, Danckert asked these patients is a problem that they have not felt bored more easily than before. "Everyone replied, yes."

These experiences make Danckert embarked on a study of the way now. As a cognitive neuroscientist at the University of Waterloo in Canada, Danckert joined the current number is still small, but growing number of researchers in the team, they are working together to undertake research on boredom.

There is no widely accepted definition of boredom. However, researchers believe that boredom is not a simple, another name for depression, or simply not interested in about things. Boredom seems to be a state of mind, people feel unhappy, the lack of a stimulus can make their escape, causing a lot of behavioral, medical, and social outcomes.
