Elucidating the Role of Microvascular Dysfunction in Heart Disease in Women

The purpose of this study is to determine if women with chest pain and "clean" heart blood vessels have impaired blood flow to the heart due to problems with the small blood vessels that provide blood and oxygen to the heart. Impairment in the small blood vessels will be tested using ultrasound pictures of the heart, called myocardial contrast echocardiography. Since these small blood vessels are not seen in a coronary angiogram, which is an x-ray of the heart vessels using a d...


Racial Differences in Control of Blood Vessel Tone and Blood Flow

Black Americans tend to die more often from and have more diseases associated with heart disease than White Americans. The exact cause of this is unknown, but it is likely a combination of genetics, behavior, risk factors, strategies for education and prevention, and socioeconomic factors. Recent studies have suggested that faster biological processes in blood vessels of Black Americans may be the cause of increased amounts of heart disease. In addition, small blood ve...

A Research Study of How Faster-acting Insulin Aspart Moves Into, Through, and Out of the Body and How it Works in the Body When Given Through an Insulin Pump to People With Type 1 Diabetes

The aim of the study is to compare the pharmacokinetics (i.e. the course of the blood concentrations of the administered trial drug) of faster-acting insulin aspart (faster aspart), and the currently marketed formulation of insulin aspart (NovoRapid®) when given as a bolus using an insulin pump in people with type 1 diabetes. The pharmacodynamic response (i.e. the course of the blood sugar lowering effect of the administered trial drug) and the safety and tolerability of faste...


Effect of Metformin on Insulin Sensitivity and Pan-Arterial Vascular Function in Adults With Metabolic Syndrome

The purpose of this study is to look at how insulin (a hormone that helps the cells get energy from sugar) in our body affects blood vessels (elasticity in the bigger blood vessels and blood flow in the smaller blood vessels in the arm) and how Metformin (a drug that makes you more sensitive to insulin) affects insulin's action on the blood vessels.

Study of Inherited Changes of Receptors Located on Blood Vessels

The renin angiotensin system is a complex process involving hormones and enzymes that regulate blood volume and blood pressure. The hormone angiotensin II is responsible for making blood vessels narrow or constrict. Angiotensin II is found in the blood and can attach to special sites called receptors on blood vessel walls. These receptors are programmed to accept angiotensin II and cause a constriction of the blood vessel. This function is found in the genetic information o...

The Role of Cyclooxygenase Activity in the Endothelial Function of Hypertensive and Hypercholesterolemic Patients

A layer of cells called the endothelium line the walls of blood vessels. These cells produce substances that control the tone of blood vessels and thus control blood flow through the vessel. This regulating activity of the endothelium is dysfunctional in several diseases of the heart and blood vessels, including high blood pressure and high levels of cholesterol. Previous research has pointed toward a decrease in the action of nitric oxide (NO) as the cause of this abn...

A Research Study Looking at How Faster Aspart Injected in Double Concentration Works in the Body of People With Type 1 Diabetes Mellitus

This study is looking at how five different formulations of faster aspart 200 U/mL reach and stay in the blood after injection. The purpose is to find a formulation that behaves similarly to the reference product called faster aspart 100 U/mL (marketed as Fiasp®). The participant will get all five formulations and the reference product. The order in which the participant gets them is decided by chance. The participant will get each medicine once during the study meaning that t...

A Pilot Trial of Itraconazole Pharmacokinetics in Patients With Metastatic Breast Cancer

Cancer cells need to be able to make new blood vessels in order to keep growing. This is called angiogenesis. In a laboratory setting, the drug itraconazole was shown to help stop the growth of new blood vessels (anti-angiogenesis). It is hoped that itraconazole will prevent new blood vessels from forming in humans too. The purpose of this study is to look at how the body processes and breaks down itraconazole (called pharmacokinetics). This study will also measure markers ...

The DVA uses an instrument which is used during routine eye examinations. The hypothesis of the study is that the changes in eye's blood vessel will be similar between the two visits; thus establishing reproducibility of the measurements for future comparisons to individuals wi...

Marinobufagenin as a Target for DIGIBIND in Preeclampsia

Background: - Preeclampsia is a combination of high blood pressure and other potentially life-threatening symptoms. Preeclampsia occurs in up to 10% of pregnancies and is a main cause of maternal and fetal death worldwide. Treatment is often difficult, and so far there is no specific and effective therapy. Researchers have been studying the body systems that regulate blood pressure. They have also studied drugs that can control certain blood c...

A Trial Comparing the Pharmacokinetic Properties of Fast-acting Insulin Aspart Between Children, Adolescents and Adults With Type 1 Diabetes

The study is done to compare how faster aspart is taken up, broken down and removed from the body between different age groups (children [6-11 years], adolescents [12-17 years] and adults [18-64 years]) who have diabetes. The blood sugar (glucose) lowering effect of faster aspart will also be investigated after consuming a meal replacement drink. The effects of faster aspart will be compared to the effects of NovoRapid®.

Treatment of Retinal Vein Occlusion (RVO) With Open-Label Anecortave Acetate (15mg.)

Retinal Vein Occlusion is a blockage of the blood vessels that drain out of the retina. Complications of retinal vein occlusion which threaten vision include neovascularization(growth of new blood vessels)and macular edema ( accumulation of fluid "leaking" from abnormal blood vessels). Currently, the treatment of retinal vein occlusion is laser photocoagulation. This treatment has found to have limited use in this type of condition.Anecortave Acetate is being considered as an a...

A Prospective Randomized Equivalence Trial to Evaluate the Safety of the Ligasure in Thyroid Surgery

This is a randomized, prospective equivalence trial on the safety of the Ligasure Vessel Sealing System as used in thyroid surgery. The Ligasure system is a hand held surgical device that uses heat to seal blood vessels during surgery. It has been a tested and accepted technology in abdominal surgery and it is now being applied to surgery of the thyroid gland because it is faster than the traditional method of tying blood vessels that a surgeon must do manually. To remove the t...

Treatment of Idiopathic Perifoveal Telangiectasia (IPT) With Open-Label Anecortave Acetate (15mg.).

Idiopathic Perifoveal telangiectasia is a poorly understood disorder that involves the growth of blood vessels around the center of the macula(perifoveal region). These blood vessels may extrend beneath the retina to produce an area of sub-retinal neosvascularization(growth of abnormal blood vessels under the retina which "leak" fluid, causing reduction in vision. Limited forms of treatment are available in managing the neovascularization and its consequences. Anecortave Acetat...

Vascular Reactivity in Kidney Disease Patients

Dialysis patients suffer from many problems with blood vessels and this is even more so for patients with the added complication of diabetes. Diabetics have a number of reasons for vascular disease and one of the new areas of research is looking at the cells that line the blood vessels, called endothelial cells. It is thought that the number of red blood cells in the blood (haemoglobin concentration) affects the function of these cells. There is very little information availabl...

The Impact of Branched-Chain Amino Acid Metabolism on Limb Dysfunction in PAD

Test the theory that abnormalities in the large blood vessels that deliver blood to your leg and the very small blood vessels in your leg's muscles (invisible to the eye) work together to worsen your leg function and walking.

Treatment of Congenital Telangiectasia (Coat's Disease) With Open-Label Anecortave Acetate (15mg.)

Congenital Telangiectasia or Coat's disease is an uncommon disorder that involves the growth of blood vessels of the macula. These blood vessels msy extend beneth the retina to produce an area of sub-retinal neovascularization(growth of abnormal blood vessels under the retina which "leak" fluid, causing reduction in vision). Limited forms of treatment are available in managing the neovascularization and its consequences. Anecortave Acetate injection will be considered as an at...

This is a Phase 1 clinical trial examining the safety, pharmacokinetics and pharmacodynamics of escalating doses of the vascular disrupting agent NPI-2358 in patients with refractory solid tumors or lymphoma. The formation of new blood vessels (angiogenesis) is an important component of tumor growth and vascular disrupting agents are intended to target the differences between these tumor blood vessels and the blood vessels in normal tissues. NPI-2358 has also been seen to dire...

Clinical Evaluation of an Investigational Blood Creatinine Point-of-Care Test Device

This study is being done to see if the Nova Creatinine Meter can give a correct measure of creatinine (a blood test used to measure kidney function) when the blood is taken from a capillary (smallest type of blood vessels). The Nova Creatinine Meter is a hand held device that can be used in a clinic to measure creatinine in about 50 seconds. Current laboratory creatinine testing can take up to an hour. Since chemotherapy patients need to have their creatinine measured prior to ...

Comparing Blood Vessel Endothelial Function in HIV-Infected People and Matched HIV-Uninfected People

The blood vessels that carry blood from the heart to the rest of the body are normally capable of relaxing and constricting when needed to provide more or less blood to the body. The inability of blood vessels to relax and widen may increase the risk of heart disease and stroke. One potential cause of this inability is inflammation. Because HIV infection is associated with inflammation, it is possible that the blood vessels in people infected with HIV may not relax properly. Th...

Study of the Response of Human Small Blood Vessels

A layer of cells called the endothelium line the walls of blood vessels. These cells produce substances that control the tone of blood vessels and thus control blood flow through the vessel. One of the substances produced involved in the control of blood vessel function is nitric oxide. Nitric oxide (NO) plays a role in the relaxation of blood vessels. Researchers have been interested in the function of the endothelium in patients with high blood pressure (essential hy...

Ranibizumab Injections to Treat Macular Telangiectasia With New Blood Vessel Growth

This study will examine whether the drug ranibizumab (Lucentis) can help prevent vision loss in people with macular telangiectasia, a condition in which new blood vessels grow in the retina at the back of the eye and can leak. Such changes in blood vessels are seen in other diseases associated with changes in a body chemical called vascular endothelial growth factor (VEGF). Ranibizumab is an anti-VEGF drug that is effective in treating another eye disease, age-related macular...
