Leducq Foundation
The Leducq Foundation (aka ''Fondation Leducq'') is a private foundation based in Paris, France. Its mission is to improve human health through international efforts to combat cardiovascular and neurovascular disease. The foundation’s principal grant program, the Transatlantic Networks of Excellence for Cardiovascular and Neurovascular Research, promotes internationally collaborative basic and transnational research. Scientists supported under this program work together to further the knowledge of cardiovascular and neurovascular disease with an aim towards improving outcomes for patients. Originally limited to investigators from Europe and North America, the Transatlantic Networks Program is, as of 2011, open to cardiovascular and neurovascular scientists worldwide. The Fondation Leducq is constituted according to French law, having a self-perpetuating Board of Directors made up of nine members, and an observer appointed by the Minister of the Interior.

Private Foundation
A private foundation is a tax-exempt organization not relying on broad public support and generally claiming to serve humanitarian purposes. The Bill & Melinda Gates Foundation is the largest private foundation in the U.S. with over $38 billion in assets.National Center for Charitable Statistics Most private foundations are much smaller. Out of the 84,000 private foundations that filed with the IRS in 2008, approximately 66% have less than $1 million in assets, and 93% have less than $10 million in assets. In aggregate, private foundations in the U.S. control over $628 billion in assets and made more than $44 billion in charitable contributions in 2007. Unlike a charitable foundation, a private foundation does not generally solicit funds from the public or have the legal requirements and reporting responsibilities of a registered, non-profit or charitable foundation. Not all foundations engage in philanthropy: some private foundations are used for estate planning purposes. Des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valvular Heart Disease
Valvular heart disease is any cardiovascular disease process involving one or more of the four valves of the heart (the aortic and mitral valves on the left side of heart and the pulmonic and tricuspid valves on the right side of heart). These conditions occur largely as a consequence of aging,Burden of valvular heart diseases: a population-based study. Nkomo VT, Gardin JM, Skelton TN, Gottdiener JS, Scott CG, Enriquez-Sarano. Lancet. 2006 Sep;368(9540):1005-11. but may also be the result of congenital (inborn) abnormalities or specific disease or physiologic processes including rheumatic heart disease and pregnancy. Anatomically, the valves are part of the dense connective tissue of the heart known as the cardiac skeleton and are responsible for the regulation of blood flow through the heart and great vessels. Valve failure or dysfunction can result in diminished heart functionality, though the particular consequences are dependent on the type and severity of valvular disease. ...

Regenerative Medicine
Regenerative medicine deals with the "process of replacing, engineering or regenerating human or animal cells, tissues or organs to restore or establish normal function". This field holds the promise of engineering damaged tissues and organs by stimulating the body's own repair mechanisms to functionally heal previously irreparable tissues or organs. Regenerative medicine also includes the possibility of growing tissues and organs in the laboratory and implanting them when the body cannot heal itself. When the cell source for a regenerated organ is derived from the patient's own tissue or cells, the challenge of organ transplant rejection via immunological mismatch is circumvented. This approach could alleviate the problem of the shortage of organs available for donation. Some of the biomedical approaches within the field of regenerative medicine may involve the use of stem cells. Examples include the injection of stem cells or progenitor cells obtained through directed differenti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venture Philanthropy
Venture philanthropy is a type of impact investment that takes concepts and techniques from venture capital finance and business management and applies them to achieving philanthropic goals. The term was first used in 1969 by John D. Rockefeller III to describe an imaginative and risk-taking approach to philanthropy that may be undertaken by charitable organizations. Examples For example, in 2000 The Chicago Public Education Fund became the only venture philanthropy in the United States focused on a single urban school district, which served as a catalyst and strategic investment partner for Mayor Richard M. Daley and four Chicago Public Schools (CPS) administrations. Other examples of this type of venture philanthropy are New Profit Inc., the Robin Hood Foundation, Tipping Point Community, Cure Alzheimer's Fund, The Redstone Acceleration & Innovation Network (TRAIN) initiative from FasterCures, the Asian Venture Philanthropy Network (AVPN), Social Ventures Australia (SVA) in Au ...

Napa Valley AVA
Napa Valley is an American Viticultural Area (AVA) located in Napa County in California's Wine Country. It was established by the Bureau of Alcohol, Tobacco and Firearms (ATF) on January 27, 1981. Napa Valley is considered one of the premier wine regions in the world. Records of commercial wine production in the region date back to the nineteenth century, but premium wine production dates back only to the 1960s. The combination of Mediterranean climate, geography and geology of the region are conducive to growing quality wine grapes. John Patchett established the Napa Valley's first commercial vineyard in 1858. In 1861 Charles Krug established another of Napa Valley's first commercial wineries in St. Helena. Viticulture in Napa suffered several setbacks in the late 19th and early 20th centuries, including an outbreak of the vine disease phylloxera, the institution of Prohibition, and the Great Depression. The wine industry in Napa Valley recovered, and helped by the results o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitral Insufficiency
Mitral regurgitation (MR), also known as mitral insufficiency or mitral incompetence, is a form of valvular heart disease in which the mitral valve is insufficient and does not close properly when the heart pumps out blood.Mitral valve regurgitation at Mount Sinai Hospital It is the abnormal leaking of blood backwards – regurgitation from the , through the mitral valve, into the |
MicroRNA
MicroRNA (miRNA) are small, single-stranded, non-coding RNA molecules containing 21 to 23 nucleotides. Found in plants, animals and some viruses, miRNAs are involved in RNA silencing and post-transcriptional regulation of gene expression. miRNAs base-pair to complementary sequences in mRNA molecules, then gene silence said mRNA molecules by one or more of the following processes: (1) cleavage of mRNA strand into two pieces, (2) destabilization of mRNA by shortening its poly(A) tail, or (3) translation of mRNA into proteins. This last method of gene silencing is the least efficient of the three, and requires the aid of ribosomes. miRNAs resemble the small interfering RNAs (siRNAs) of the RNA interference (RNAi) pathway, except miRNAs derive from regions of RNA transcripts that fold back on themselves to form short hairpins, whereas siRNAs derive from longer regions of double-stranded RNA. The human genome may encode over 1900 miRNAs, although more recent analysis suggests that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stroke
A stroke is a medical condition in which poor blood flow to the brain causes cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than one or two hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. A hemorrhagic stroke may also be associated with a severe headache. The symptoms of a stroke can be permanent. Long-term complications may include pneumonia and loss of bladder control. The main risk factor for stroke is high blood pressure. Other risk factors include high blood cholesterol, tobacco smoking, obesity, diabetes mellitus, a previous TIA, end-st ...

Vascular Malformation
A vascular malformation is a blood vessel or lymph vessel abnormality. Vascular malformations are one of the classifications of vascular anomalies, the other grouping is vascular tumors. They may cause aesthetic problems as they have a growth cycle, and can continue to grow throughout life. Vascular malformations of the brain (VMBs) include those involving capillaries, and those involving the veins and arteries. Capillary malformations in the brain are known as cerebral cavernous malformations or ''capillary cavernous malformations'' (CCMs). Those involving the mix of vessels are known as cerebral arteriovenous malformations (AVMs or cAVMs). The arteriovenous type is the most common in the brain. Types A simple division of the vascular malformations is made into ''low-flow'' and ''high-flow'' types. Low-flow malformations involve a single type of blood or lymph vessel, and are known as ''simple vascular malformations''; high-flow malformations involve an artery. There are also ma ...

Ischemic Preconditioning
Ischemic preconditioning (IPC) is an experimental technique for producing resistance to the loss of blood supply, and thus oxygen, to tissues of many types. In the heart, IPC is an intrinsic process whereby repeated short episodes of ischaemia protect the myocardium against a subsequent ischaemic insult. It was first identified in 1986 by Murry ''et al.'' This group exposed anesthetised open-chest dogs to four periods of 5 minute coronary artery occlusions followed by a 5-minute period of reperfusion before the onset of a 40-minute sustained occlusion of the coronary artery. The control animals had no such period of “ischaemic preconditioning” and had much larger infarct sizes compared with the dogs that did. The exact molecular pathways behind this phenomenon have yet to be fully understood. Background If the blood supply to an organ or a tissue is impaired for a short time (usually less than five minutes) then restored so that blood flow is resumed, and the process repea ...

Congenital Heart Disease
A congenital heart defect (CHD), also known as a congenital heart anomaly and congenital heart disease, is a defect in the structure of the heart or great vessels that is present at birth. A congenital heart defect is classed as a cardiovascular disease. Signs and symptoms depend on the specific type of defect. Symptoms can vary from none to life-threatening. When present, symptoms may include rapid breathing, bluish skin (cyanosis), poor weight gain, and feeling tired. CHD does not cause chest pain. Most congenital heart defects are not associated with other diseases. A complication of CHD is heart failure. The cause of a congenital heart defect is often unknown. Risk factors include certain infections during pregnancy such as rubella, use of certain medications or drugs such as alcohol or tobacco, parents being closely related, or poor nutritional status or obesity in the mother. Having a parent with a congenital heart defect is also a risk factor. A number of genetic condition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypertension
Hypertension (HTN or HT), also known as high blood pressure (HBP), is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. High blood pressure usually does not cause symptoms. Long-term high blood pressure, however, is a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral arterial disease, vision loss, chronic kidney disease, and dementia. Hypertension is a major cause of premature death worldwide. High blood pressure is classified as primary (essential) hypertension or secondary hypertension. About 90–95% of cases are primary, defined as high blood pressure due to nonspecific lifestyle and genetic factors. Lifestyle factors that increase the risk include excess salt in the diet, excess body weight, smoking, and alcohol use. The remaining 5–10% of cases are categorized as secondary high blood pressure, defined as high blood pressure due to an identifiable cause, such ...
