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.

Linagliptin for sale
Product name:Linagliptin
CAS:668270-12-0
Molecular Formula:C25H28N8O2
Formula Weight:472.54g/mol
Description:The low therapeutic dose of linagliptin, the long-lasting inhibition of DPP-4 activity and the good safety/tolerability profile exhibited thus far suggest that linagliptin may be superior to competitors. The results from ongoing phase III clinical trials will provide further information on such aspects; however, from the available data, linagliptin appears to have promise for market success.

World Health Organization declared an end to the Ebola outbreak in West Africa
With Ebola epidemic in Liberia on the 14th end, West Africa all known chains of transmission of Ebola virus have been suppressed.
According to the provisions of the WHO, more than 42 days to no new cases of Ebola outbreak ended. The 14th from Liberia last one confirmed by two tests were negative patients has reached 42 days. Liberia had first announced in May 2015 Ebola not spread, but the virus appeared twice since then to re-enter the case. The most recent case occurred in November 2015.
Liberia marks the end of the Ebola epidemic outbreaks since two years ago, Liberia and Guinea, Sierra Leone, the three most affected countries in West Africa, for the first time to achieve zero cases reported at least 42 days. November 7, 2015 Sierra Leone epidemic ended, December 29 Guinea epidemic ended.
WHO Director-General Margaret Chan said the virus was found and destroyed each chain is a landmark achievement in West Africa, it depends on the joint efforts of the three governments in West Africa, heroic medical staff, local and international organizations and generous partners.
UN Secretary-General Ban Ki-moon said through a spokesman for the national authorities affected by Ebola demonstrated leadership and commitment in combating outbreaks and community aspects of ownership and participation spirit demonstrated to be commended.
The Ebola epidemic claimed more than 11,300 lives, the number of infections by more than 28,500 cases, the affected country, families, communities and cause huge health and economic impact.
However, the WHO warned that, as in the case in Liberia appear before it, the three countries still in a small Ebola outbreaks occur more highly risk. So far, it has been confirmed that there has been no outbreak of 10 belong to the original case of emergency situations, and may be due to the virus after rehabilitation persist in the body caused by the survivors. There is evidence that the virus in the body disappear relatively quickly survivors, but can survive up to a year in a small number of sperm in male survivors, and in rare cases will be passed by an intimate partner.
WHO said it will collaborate with partners and the three governments in West Africa, to ensure access to medical and psychological rehabilitation of the patient care, the residual virus detection, provide counseling and education to help them integrate into family and community life, and try to spread the risk of the virus dropped again lowest.
