*  Evidence for involvement of both IKCa and SKCa channels in hyperpolarizing responses of the rat middle cerebral artery. -...
BACKGROUND AND PURPOSE: Endothelium-derived hyperpolarizing factor responses in the rat middle cerebral artery are blocked by inhibiting IKCa channels alone, contrasting with peripheral vessels where block of both IKCa and SKCa is required. As the contribution of IKCa and SKCa to endothelium-dependent hyperpolarization differs in peripheral arteries, depending on the level of arterial constriction, we investigated the possibility that SKCa might contribute to equivalent hyperpolarization in cerebral arteries under certain conditions. METHODS: Rat middle cerebral arteries (approximately 175 microm) were mounted in a wire myograph. The effect of KCa channel blockers on endothelium-dependent responses to the protease-activated receptor 2 agonist, SLIGRL (20 micromol/L), were then assessed as simultaneous changes in tension and membrane ...

*  The Linear Behavior of the System Middle Cerebral Artery Flow Velocity and Blood Pressure in Patients With Migraine | Stroke
Our approach to look at cerebral autoregulation in migraineurs showed 2 striking results. First, the phase and gain behavior was completely different compared with the controls, and second, the spectral power magnitudes of BP and V were very much increased in the migraineurs.. One interpretation of the transfer function approach is to consider the cerebrovascular system as a high-pass filter, which delays low frequencies and lets pass through the higher beat-by-beat-depending frequencies.6,7 Phase and gain are 2 parameters to describe the filter. The findings in our controls can be interpreted in exactly that way. The V lead over BP in the controls means that slow BP changes are delayed before they enter the cerebrovascular bed. In migraineurs, the phase shift indicates that BP is always earlier in time than V, hence BP is driving V. If the filter indicates the presence or absence of cerebral autoregulation, it is evident that migraine ...

*  hypercapnia | Cerebral Autoregulation
Authors: Kostoglou K, Debert CT, Poulin MJ, Mitsis GD.. We examined the time-varying characteristics of cerebral autoregulation and hemodynamics during a step hypercapnic stimulus by using recursively estimated multivariate (two-input) models which quantify the dynamic effects of mean arterial blood pressure (ABP) and end-tidal CO2 tension ( [Formula: see text] ) on middle cerebral artery blood flow velocity (CBFV). Beat-to-beat values of ABP and CBFV, as well as breath-to-breath values of [Formula: see text] during baseline and sustained euoxic hypercapnia were obtained in 8 female subjects. The multiple-input, single-output models used were based on the Laguerre expansion technique, and their parameters were updated using recursive least squares with multiple forgetting factors. The results reveal the presence of nonstationarities that confirm previously reported effects ...

*  Effects of oxygen and glucose deprivation on vasoactivity in isolated bovine middle cerebral arteries. | Stroke
The effects of oxygen and glucose deprivation on vasoactivity were investigated using helical strips of bovine middle cerebral artery. Hypoxia, created by reducing the PO2 of the bath, or oxidative inhibition with 2,4 dinitrophenol (DNP) or sodium azide, significantly reduced contractions induced by serotonin. Normal tonic contractions induced with fresh and aged whole blood, or 5-HT became phasic and quickly relaxed to baseline in a hypoxic environment. Glucose elimination from the Krebs medium, or the inhibition of the glycolytic pathway with iodoacetic acid (IAA), did not significantly reduce serotonin-induced contractions. However, contractions were inhibited more with the combination of oxygen and glucose deprivation, or DNP + IAA, than with oxygen deprivation alone. Efforts to produce rigor in this preparation by oxygen/substrate reduction or metabolic inhibition were unsuccessful. Tonic contractions induced by 70 mM potassium became ...

*  Prolonged exposure to oxyhemoglobin modifies the response of isolated dog middle cerebral arteries to vasoactive substances. |...
We exposed helical strips of dog middle cerebral arteries to oxyhemoglobin for 5 hours, rinsed them with bathing medium, and stored them overnight; we compared the responses of strips thus treated with the responses of strips without oxyhemoglobin treatment. Relaxation induced by nicotine was abolished by hexamethonium and was markedly inhibited after exposure to oxyhemoglobin. A low concentration of KCl (5 mM) elicited relaxation that was abolished by ouabain and significantly reduced by oxyhemoglobin. Endothelium-dependent relaxation caused by calcium ionophore A23187 was attenuated, and that caused by substance P was reversed to contraction after exposure to oxyhemoglobin. Contraction elicited by substance P also depended on endothelium and was abolished by indomethacin. Relaxation induced by TRK-100, a stable analogue of prostaglandin I2, was moderately attenuated by oxyhemoglobin. On the other hand, concentration-dependent relaxation induced by ...

The purpose of this study was to characterize cerebrovascular responses to rowing exercise, investigating whether their diurnal variation might explain performance differences across a day. Twelve male rowers completed incremental rowing exercise and a 2000-m ergometer time trial at 07:00 h and 16:00 h, 1 week apart, while middle cerebral artery velocity (MCAv), cerebral (prefrontal), and muscular (vastus lateralis) tissue oxygenation and hemoglobin volume (via near-infrared spectroscopy), heart rate, and pressure of end-tidal CO2 (PET CO2) were recorded. MCAv was 20-25% above resting levels (68 ± 12 cm/s) during submaximal and maximal exercise intensities, despite PET CO2 being reduced during maximal efforts (down ∼ 0.5-0.8 kPa); thus revealing a different perfusion profile to the inverted-U observed in other exercise modes. The afternoon time trial was 3.4 s faster (95% confidence interval 0.9-5.8 s) and ...
