Effect of a Single High-Fat Meal and Vitamins on the Circulatory Response to Local Heat in Koreans and Caucasians
Blood flow mediated by the vascular endothelium plays an important role in removing heat from the skin. Asians who have thrifty genes have impaired endothelial function (EF) due to the westernized high fat (HF) dietary lifestyle. Hypertriglyceridemia (HTG) can produce free radicals which reduces …

Procerum root disease physiology and disease interactions with ozone
… xylem at the stem base may be responsible for vascular occlusion leading to severe water deficits and mortality. The pathogen has been isolated from the roots of ozone-sensitive eastern white pines in the field, although not from nearby tolerant trees, and it may be that ozone sensitivity …

Roles of coagulation factor XIII in the functions of blood platelets
… factors in forming blood clots at sites of vascular injury. Platelets are recruited from flowing blood and become activated to fulfil their haemostatic roles (Marcus, 1969, Ruggeri and Mendolicchio, 2007). Coagulation factors are also spatially activated at these sites where they initiate, …

Retinale Ischämie bei der intraluminalen Fadenokklusionsmethode
… Immunhistochemistry revealed that the vascular occlusion induced an expression of GFAP and OX-42 with a maximum of immunoreactivity after 3 days. There was no significant increase of cytokine immunhistochemisty. Histological changes such as neuron lost or edema of the inner retinal …

Influence of Cardiovascular Risk factors on Remote Ischemic Preconditioning
<p>A powerful therapy against microvascular endothelial ischemia-reperfusion injury is remote ischemic preconditioning (rIPC), which triggers tissue protection by exposing a limb to small cycles of vascular occlusion. Animal models indicate that CVD risk factors reduce the protective benefits of …

Investigating the impact of endothelial BMPR2 loss on the proliferative response to bone morphogenetic protein 9 in pulmonary arterial hypertension
… hypertension (PAH) is a disease of proliferative vascular occlusion that is strongly linked to heterozygous mutations in BMPR2, the gene encoding the bone morphogenetic protein (BMP) type II receptor (BMPR-II). The endothelial-selective BMPR-II ligand, BMP9, has been shown to reverse disease in …

Ultrasound tissue perfusion imaging
… in a tissue mass is an indication of neo-vascularity and potential malignancy. Ultrasonic pulsed Doppler imaging is a safe and economical modality for noninvasive monitoring of blood flow. However, weak blood echoes make it difficult to detect perfusion using standard methods without the …

Unraveling the Role of EphA4 in Immune-Mediated Arteriogenesis After Ischemic Stroke
… resulting from ischemic events often caused by occlusion of the middle cerebral artery (MCA). Pre-existing leptomeningeal collateral (LMC) vessels connect MCA branches to anterior or posterior arteries, situated along the brain's cortical surface or meninges, under healthy conditions these …

Thermal analysis of vascular reactivity
Cardiovascular disease (CVD) is the leading cause of death in the United States. Analysis of vascular reactivity (VR) in response to brachial artery occlusion is used to estimate arterial health and to determine the likelihood of future cardiovascular complications. Development of a sensitive …

Mechanisms of Blood Flow Restriction Exercise in Skeletal Muscle Adaptations
… low-intensity resistance coupled with local vascular occlusion called “blood flow restriction” (BFR) exercise has emerged as an exercise that stimulates muscle growth and muscle protein synthesis to a similar extent for all adults. Research in the past two decades on BFR exercise has been …

Reactive Oxygen Species (ROS) Triggered Delivery System for the Treatment of Diabetic Retinopathy
… characterized by neurodegeneration, increased vascular permeability, progressive vascular occlusion, followed by neovascularization at later stages due to increased expression of vascular endothelial growth factor (VEGF) and proliferation of basal epithelial cells. Celecoxib is reported to be …

Understanding the mechanisms of phosphatidylserine exposure in sickle cells
… hallmark complications of the disease such as vascular occlusion, anaemia and inflammation. This study investigates the possible physiological and cellular signalling pathways involved in PS exposure in RBCs from SCD patients. In the first part, conditions specific to the renal medulla were …

An in-shoe gait analysis device to measure the maximum shear stresses at the first metatarsal head
… are thought to have an effect on blood flow occlusion elsewhere in the body. The reduced blood flow may relate in moderation to reduced tissue tolerance or repair capability or even in more severe cases to cell death. Repeated vascular occlusion in a normal person would produce a minor …

The effects of melatonin on vascular function, oxidative stress and blood pressure reactivity during a high sodium diet

Molecular imaging of spatio-temporal distribution of angiogenesis in hindlimb ischemia model and diabetic milieu
… response to ischemia was perfomed. After vascular occlusion, ischemic angiogenesis is an important reparative mechanism and can ameliorate the outcome of ischemic disease. Diabetic foot ulcers affect almost 15% of diabetic patients and are the leading cause of amputations worldwide (Yoon …
