How do Circulating Precursor Endothelial Cells contribute to newly formed vessels

Endothelial cells derive from cells in the bone marrow. Circulating precursor endothelial cells contribute to newly forming vessels.

Do Alk 1 and/or Endogln mutations affect the functions of these cells once they incorporate into growing vessels. These vessels then go on to form arteriovenous malformations

Goal 2: Reduce Human Disease

what are the molecular pheontypic differences in IPF/ILD

What are the molecular phenotypic differences in blood and tissue of IPF ILD and how do they relate to disease course and potential response to therapy. There is a need to gain understanding in humans of the differences and similarities in iPF and iLD in general to eliminate the idiopathic nature and establish human targets. The challenge is coupling such research to longer term studies/outcomes and potentially clinical ...more »

Consequences of ABO or Rh Type Specific versus Non-Type Specific Platelet Transfusions

What are the consequences, clinically and immunologically, of ABO or Rh type specific vs. non-type specific platelet transfusions? There is widely varying practice as to ABO and Rh matching of platelets for transfusion. Most studies demonstrate that use of ABO unmatched (non-identical) platelets are associated with increased 1) platelet refractoriness (small randomized trials), 2) red cell transfusion needs and hemolysis, ...more »

Sleep Disorders and Brain Maturation

What is the effect of sleep disorders on child development? Specifically, how sleep apnea with intermittent hypoxia and or sleep deprivation alters the normal trajectory of maturation of brain regions controlling cognition, behavior and the cardiovascular system?

Goal 2: Reduce Human Disease

Can one integrate cardiac imaging studies with genetic,clinical, "omics", and historical data to predict disease and personalize

There are many novel imaging modalities, including radiographic, scintigraphic, sonographic, MR-based, and molecular for the heart and vessels. Patients have unique medical "signatures"- genetic risk factor profiles, epigenetic markings, "omics" profiles, and personal clinical and family history as well as symptom constellation and physical exam findings. Can these all be integrated into a single personalized profile ...more »

Goal 2: Reduce Human Disease

What about the impact of regulation of genes in response to external stimulation on human health

We are focusing a lot on the genes that may be protective or harmful to our lives. But what about the regulation of genes in response to external stimulations, such as psychosocial and/or environmental, that are probably more accountable for whether we live healthier or not.

The Investigator's Catch-22: How Can NHLBI Help?

The Critical Challenge is to determine how NHLBI can continue to foster the translational research necessary to allow our researchers to further develop their NHLBI-funded basic science discoveries. Researchers can't readily get a "typical" grant to perform the preclinical and early clinical translational IND-enabling research, and also can't yet attract private sector support without having done the work to "de-risk" ...more »

Direct thrombin inhibitors and anti-Xa (Ten A) inhibitors in trauma patients - physiologic effects and impact on outcomes

Direct thrombin inhibitors and anti-Xa (Ten A) inhibitors are new, undetectable and irreversible. We have no data on how well these drugs correlate with current measures of coagulopathy such as thromboelastography, or whether antifibrinolytics should be used in patients who are on these drugs. These drugs may increase incidence of traumatic brain injury after minor injury. They are also going to be used increasingly in ...more »

Goal 1: Promote Human Health

The coupling of mechanical stress to biochemistry, molecular biology and electrophysiology

Cells aren’t beakers holding soluble reactants waiting to be mixed. Cells are structured objects where life forms as a flow of free energy between three pools: chemical, electrical and mechanical. Most papers in the literature ignore structure (except of Xray or EM of specific proteins) and almost all ignore the coupling of mechanics to the other pools. Cells cannot be studied with in vitro experiments. We can study single ...more »

Goal 3: Advance Translational Research

Advanced Models for Translational Cardiovascular Research and Drug Development

Although the study of the cardiovascular (CV) system has benefited significantly from the use of gene-targeted and transgenic mouse models, small rodents do not always accurately reflect human cardiovascular physiology. Many discoveries using mouse CVD models failed to translate into human applications.
