Use of Laser Speckle to Study Cutaneous Blood Flow at Exercise in Healthy Subjects

2014-08-27 03:12:37 | BioPortfolio


We aim to test the hypothesis that Laser speckle contrast imaging allows for the measurement of cutaneous blood flow during exercise.


Ischemia and post occlusive reactive hyperhemia in the skin is tested in healthy normal subjects at rest and during cycle exercise.

The Effect of Pregabalin Given Preoperatively on the Tourniquet Induced Ischemia-reperfusion

The application of tourniquet is indispensable for a bloodless surgical area in total knee arthroplasty surgery. The release of tourniquet produces reactive oxygen species which can cause ...

The Role of SCUBE-1 in Ischemia-reperfusion Injury

One consequence of tissue damage caused by tourniquet is ischemia-reperfusion injury. Short-term ischemia leads to vasodilatation and reactive hyperemia resulting in post-ischemic reperfus...

Changes in Tissue Microcirculation During Ischemic Conditioning: Pilot Study

Changes in tissue microcirculation during ischemic conditioning (4 cycles of 5-min ischemia and 5-min reperfusion) has not been well documented. In previous studies, there was difference i...

Effect of Tourniquet Use on Muscle Thigh Function.

The use of a pneumatic tourniquet with the purpose of maintaining an operative field free of blood is a common practice in orthopedic surgery. Its use is associated with local and systemic...

Ischemia and Reperfusion Injury in the Human: An Observational Study

We, the researchers at Lawson Health Research Institute, propose to investigate the impact of surgical ischemia and reperfusion on skeletal muscle microcirculation using a hand-held micros...

Does Tourniquet Time or Pressure Contribute to Intracranial Pressure Increase Following Tourniquet Application?

The aim of this study was to determine whether an early increase in intracranial pressure (ICP) following the deflation of a tourniquet is related to the tourniquet time (TT) or tourniquet pressure (T...

The Combat Application Tourniquet Versus the Tactical Mechanical Tourniquet.

Exsanguination from limb injury is an important battlefield consideration that is mitigated with the use of emergency tourniquets. The Combat Application Tourniquet (C-A-T®) is the current British mi...

Comparison of coronary angiography and intracoronary imaging with fractional flow reserve for coronary artery disease evaluation: An anatomical-functional mismatch.

Myocardial ischemia is a leading cause of death worldwide, and it corresponds to the imbalance between blood supply and myocardial demand. Epicardial coronary artery disease (CAD) is detected on the b...

Voluntary running protects against neuromuscular dysfunction following hindlimb ischemia-reperfusion in mice.

Ischemia-reperfusion (IR) due to temporary restriction of blood flow causes tissue/organ damages under various disease conditions, including stroke, myocardial infarction, trauma and orthopedic surger...

Study of Tourniquet Use in Simulated First Aid: User Judgment.

The purpose of this study was to survey the judgments of tourniquet users in simulation to discern opportunities for further study.

Medical and Biotech [MESH] Definitions

A disorder characterized by a reduction of oxygen in the blood combined with reduced blood flow (ISCHEMIA) to the brain from a localized obstruction of a cerebral artery or from systemic hypoperfusion. Prolonged hypoxia-ischemia is associated with ISCHEMIC ATTACK, TRANSIENT; BRAIN INFARCTION; BRAIN EDEMA; COMA; and other conditions.

The circulation of the BLOOD through the MICROVASCULAR NETWORK.

The chilling of a tissue or organ during decreased BLOOD perfusion or in the absence of blood supply. Cold ischemia time during ORGAN TRANSPLANTATION begins when the organ is cooled with a cold perfusion solution after ORGAN PROCUREMENT surgery, and ends after the tissue reaches physiological temperature during implantation procedures. WARM ISCHEMIA TIME starts then and ends with completion of SURGICAL ANASTOMOSIS.

Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.

A distinct and virulent form of DENGUE characterized by thrombocytopenia and hemoconcentration (grades I and II) and distinguished by a positive tourniquet test. When accompanied by circulatory failure and shock (grades III and IV), it is called dengue shock syndrome. (From Dorland, 28th ed)
