A diverse superfamily of proteins that function as translocating proteins. They share the common characteristics of being able to bind ACTINS and hydrolyze MgATP. Myosins generally consist of heavy chains which are involved in locomotion, and light chains which are involved in regulation. Within the structure of myosin heavy chain are three domains: the head, the neck and the tail. The head region of the heavy chain contains the actin binding domain and MgATPase domain which provides energy for locomotion. The neck region is involved in binding the light-chains. The tail region provides the anchoring point that maintains the position of the heavy chain. The superfamily of myosins is organized into structural classes based upon the type and arrangement of the subunits they contain.

Capillary refill and core-peripheral temperature gap as indicators of haemodynamic status in paediatric intensive care patients. (1/47)

OBJECTIVES: Capillary refill time is an important diagnostic adjunct in the acute resuscitation phase of the shocked child. This study assesses its relation to commonly measured haemodynamic parameters in the postresuscitation phase when the child has reached the intensive care unit, and compares this with core-peripheral temperature gap. METHODS: Ninety standardised measurements of capillary refill time were made on 55 patients, who were divided into postcardiac surgery (n = 27), and general (n = 28), most of whom had septic shock (n = 24). A normal capillary refill time was defined as < or = 2 seconds. Measured haemodynamic variables included: cardiac index, central venous pressure, systemic vascular resistance index, stroke volume index (SVI), and blood lactate. Seventy measurements were made on patients while being treated with inotropes or vasodilators. RESULTS: Capillary refill time and temperature gap both correlated poorly with all haemodynamic variables among post-cardiac surgery children. For general patients, capillary refill time was related to SVI and lactate; temperature gap correlated poorly with all variables. General patients with a prolonged capillary refill time had a lower median SVI (28 v 38 ml/m2) but not a higher lactate (1.7 v 1.1 mmol/l). A capillary refill time of > or = 6 seconds had the best predictive value for a reduced SVI. CONCLUSION: Among ventilated, general intensive care patients, capillary refill time is related weakly to blood lactate and SVI. A normal value for capillary refill time of < or = 2 seconds has little predictive value and might be too conservative for this population; septic shock.  (+info)

Vascular and stromal features in the skin of the lower limb in patients with chronic critical limb ischaemia (CLI) and oedema. (2/47)

OBJECTIVE: peripheral oedema is often observed in limbs affected by chronic critical limb ischaemia (CLI) and is mainly subcutaneous in distribution. Previous work has shown that capillary filtration coefficient (CFC) in limbs with CLI and oedema was twice as great as that in the contralateral limb. These changes might be due to morphological changes. Transmission electron microscopy (TEM) was used to examine the morphological features of the capillary walls and surrounding stromal tissues in the skin of these limbs. MATERIAL AND METHODS: eight patients with unilateral CLI and peripheral pitting oedema (four men, four women, a mean age of 81+/-6.9 years) was studied. Skin biopsies were taken from the pulp of the first toe, interdigital space between the first and second digits and dorsal part of forefoot just prior to amputation. RESULTS: stromal oedema and dilated capillaries were most prominent in the distal part of the foot. Some of the capillaries were filled with blood cells and some were empty. The endothelium of the dilated vessels was elongated and distended. In some patients a number of capillaries were collapsed with degenerate endothelial cells. <<<>>>, i.e. large openings, were found between the elongated oedematous endothelial cells. The basal lamina was thickened in all patients. Stromal haemorrhage and degeneration were seen in approximately 50% of patients. CONCLUSION: CLI causes ultrastructural changes in the capillary endothelium and surrounding stroma. The presence of large gaps between endothelial cells as well as an increased capillary pressure may enhance transcapillary transudation, and are most likely the causative factors in the formation of the ischaemic oedema. The stromal haemorrhage as well as degeneration probably signifies a terminal stage of CLI.  (+info)

Fluid flow induces upregulation of synthesis and release of tissue factor pathway inhibitor in vitro. (3/47)

Fluid flow modulates the synthesis and secretion by endothelial cells (ECs) of several proteins that control the hemostatic properties of the vessel wall. Tissue factor pathway inhibitor (TFPI), also synthesized by ECs, is the main downregulator of tissue factor-dependent procoagulant activity. In the present study, we investigated the effect of physiological shear stress on the expression, distribution, and release of TFPI in cultured ECs. The EA.hy926 cell line was grown in a hollow-fiber perfusion system and exposed for variable times to different shear values: 0.27 dyne/cm(2) (minimal flow), 4.1 dyne/cm(2) (venous flow), and 19 dyne/cm(2) (moderate arterial flow). Step increase of the shear stress from 0.27 to 19 dyne/cm(2) induced a sharp increase of TFPI released into the medium and a parallel decrease and redistribution of cell-associated TFPI, which suggests that an acute release of TFPI occurred from the cellular pools. During 24 hours of high shear stress, cell-associated TFPI antigen and mRNA increased time-dependently. Subjecting ECs to steady shear stress for 72 hours also upregulated the expression and production of TFPI, in direct correlation with the degree of the shear. The secretion of TFPI was enhanced 1.9-fold under venous flow and 2.4-fold under arterial flow compared with minimal flow. Equally, cell-associated TFPI antigen and cell surface TFPI activity increased proportionally with the shear stress. The expression of TFPI mRNA, as determined by Northern blotting, increased up to 2-fold in ECs under venous flow and up to 3-fold under arterial flow. These results suggest that shear forces regulate TFPI by modulating its release and gene expression in ECs in vitro.  (+info)

Decrease in coronary blood flow reserve during hyperlipidemia is secondary to an increase in blood viscosity. (4/47)

BACKGROUND: During maximal hyperemia, capillaries provide the greatest resistance to flow. A major determinant of capillary resistance is viscosity. We, therefore, hypothesized that abnormal coronary blood flow (CBF) reserve observed during hyperlipidemia is secondary to increased blood viscosity and not abnormal coronary vasomotion. METHODS AND RESULTS: Maximal hyperemia was induced in 9 dogs using adenosine. Serum triglyceride levels were increased by incremental doses of Intralipid. A good correlation was noted between serum triglyceride levels and blood viscosity (r=0.82). Neither total coronary blood volume nor myocardial blood volume changed with increasing serum triglyceride levels, indicating lack of vasomotion. Myocardial vascular resistance (MVR) increased with increasing triglyceride levels (r=0.84), while hyperemic myocardial blood flow (MBF) decreased (r=-0.64). The decrease in hyperemic MBF was associated with a decrease in blood velocity (r=-0.56). These findings were confirmed with direct intravital microscopic observations in the mice cremaster muscle. CONCLUSIONS: Increasing lipid levels in a fully dilated normal coronary bed causes no change in large or small vessel dimensions. Instead, the increase in blood viscosity causes capillary resistance to rise, which attenuates hyperemic CBF. Therefore, the abnormal CBF reserve associated with hyperlipidemia is due to increase blood viscosity and not abnormal vascular function.  (+info)

Capillary and cell wall permeability to potassium in isolated dog hearts. (5/47)

From venous tracer-dilution curves recorded after 36 pulse injections of 42KCl and 131I-labeled albumin into the coronary artery inflow of 15 isolated canine heart preparations, we calculated maximal fractional extractions (Emax) and capillary permeability-surface area products (PScap) for 42K+ over a range of plasma flows (FP) from 0.3 to 1.7 ml min-1 g-u. At low FP (less than 1.0), Emax was 0.60 +/- 0.0l (mean +/- SD) and PScap was 0.72 +/- 0.20 ml min-1 g-1; at high FP (greater than 1.0), Emax decreased to 0.49 +/- 0.05 and PScap increased to 1.06 +/- 0.18. Continuous recording (gamma detector) of residual myocardial 42K+ in seven hearts showed that the mean fractional escape rate of tracer between 30 and 60 min after injection was 0.011-0.023 min-1; higher rates were observed at high FP, when the residue of 42K+ decreased to less than 10% of the injected dose by 60 min. Using PScap measured at high FP and considering the virtual intracellular volume of distribution for K+ to be 20 ml/g, we calculated the permeability-surface area product for sarcolemma (PScw) as 0.54-0.73 ml min-1 g-1, or about 50% of PScap. Considering sarcolemmal surface area (Scw) as 4,200 cm2/g and capillary surface area (Scap) as 500 cm2/g, cell permeability is low, with Pcw:Pcap being less than 0.08.  (+info)

Postural changes in capillary pressure in the hallux of healthy volunteers. (6/47)

Capillary circulation is delicately regulated by microvascular constriction mechanisms, thereby controlling capillary perfusion and transmural pressure. The influence of posture on capillary flow has been investigated in both diseased and healthy people. However, its influence on capillary pressure has rarely been investigated. We measured capillary pressures in the supine and sitting positions in the hallux of healthy volunteers. The capillaries in the eponychium of the hallux were punctured by using a micropipette connected to a micropressure system (900A, WPI). Also, peripheral arterial and venous pressures were measured in both positions. The rise in systolic capillary pressure from supine to sitting position (32 mmHg; from 39 to 71 mmHg, respectively) was significantly (P < 0.001) smaller than the rise in systolic arterial toe pressure (57 mmHg, from 87 to 144 mmHg, respectively) and venous pressure (41 mmHg, from 26 mmHg to 67 mmHg, respectively). This study shows that the postural rise in precapillary arteriolar pressure is not completely transmitted to the capillaries, probably because of activation of peripheral vasoconstriction mechanisms.  (+info)

Effect of captopril on the release of the components of the renin-angiotensin system into plasma and lymph. (7/47)

The effects of captopril on the intrarenal renin-angiotensin system were assessed from measurements in arterial plasma, renal venous plasma, and renal lymph from salt-depleted dogs. In the basal state, immunoreactive angiotensin II (Ang II) in renal venous plasma averaged only 60 +/- 12% (P less than 0.01) of arterial plasma, although the concentration of Ang II in renal lymph was 2.0 +/- 0.4-fold (P less than 0.05) greater. The Ang II concentration of renal lymph incubated ex vivo at 37 degrees C doubled in 10 to 15 min, which was the time taken to collect renal lymph samples. Compared with arterial plasma, renal lymph contained lower concentrations (P less than 0.01) of renin substrate and angiotensin-converting enzyme but higher concentrations of active (5.3 +/- 2.1-fold) and inactive (8.9 +/- 3.2-fold) renin. Although captopril increased the secretion of active renin into renal venous plasma by six-fold, the secretion of total renin was unchanged because of a reciprocal fall in the secretion of inactive renin. The percent reduction in renal vascular resistance with captopril correlated with the percent fall in Ang II in renal lymph (r = 0.70). IN CONCLUSION: (1) all components of the renin-angiotensin system are represented in the renal interstitium, as reflected in lymph; (2) Ang II concentrations in renal lymph in vivo approximate arterial levels; (3) increased secretion of active renin into plasma during intrarenal infusion of captopril into denervated kidneys is due predominantly to renin activation; and (4) renal vascular resistance may depend on the concentration of Ang II in the renal interstitium.  (+info)

A novel application of myocardial contrast echocardiography to evaluate angiogenesis by autologous bone marrow cell transplantation in chronic ischemic pig model. (8/47)

OBJECTIVES: We investigated the feasibility of myocardial contrast echocardiography (MCE) to evaluate regional perfusion after bone marrow cell transplantation. BACKGROUND: The myocardial microvessels improved by cell transplantation are too small to visualize with conventional angiography. METHODS: Fourteen mini-pigs from the Nippon Institute for Biological Science were used. The proximal left anterior descending coronary artery was ligated. One month later, nine pigs survived. Six pigs received autologous cell transplantation into the left ventricular anterior wall: bone marrow mononuclear cells (BMMNCs) (n = 3) and bone marrow stromal cells (BMSCs) (n = 3). The other three pigs received saline (control group, n = 3). The pigs were sacrificed one month later. Myocardial contrast intensity (MCI) with a contrast agent was measured using the SONOS 5500 system (Philips). Capillary density (CD) and MCI were measured at four areas: anteroseptum (nontransplanted infarct area), anterior wall (transplanted infarct area), septum (border zone), and lateral wall (normal). We compared the anteroseptum with the anterior wall by MCI and CD. RESULTS: In the BMMNC and BMSC subsets, the CD of the anterior wall was higher than that of the anteroseptum (p < 0.001). There was a linear relation between MCI and CD (acoustic unit [AU2] = 0.234 CD + 0.010, r = 0.92, p < 0.001). At one month after cell transplantation, MCI of the anterior wall increased in the BMMNC and BMSC subsets (p < 0.05), although it did not change in the control group. The ratio of wall thickness (systole/diastole) in the transplanted infarct area was larger than that in the nontransplanted infarct area (p < 0.01). CONCLUSIONS: Myocardial contrast echocardiography is useful to evaluate regional perfusion, which was enhanced by bone marrow cell transplantation.  (+info)

The criterion for the diagnosis of scurvy had been, until recently, the appearance of the symptoms of scurvy. As a result of the experimental work in vitamin C, three new diagnostic procedures have now come into use: the capillary resistance test, the concentration of vitamin C in the blood and the urinary excretion of vitamin C.1, 2, 3, 4, 5 There is still some controversy as to the value of capillary resistance tests as an index of vitamin C deficiency. We have studied the capillary resistance of 25 young normal adults by the Dalldorf method5 and found no definite relation ...
In 1996, Kirk Lancaster and David Siegel investigated the existence and behavior of radial limits at a corner of the boundary of the domain of solutions of capillary and other prescribed mean curvature problems with contact angle boundary data. They provided an example of a capillary surface in a unit disk D which has no radial limits at (0, 0) is an element of partial derivative D. In their example, the contact angle, gamma, cannot be bounded away from zero and pi. Here we consider a domain Omega with a convex corner at (0, 0) and find a capillary surface z = f (x, y) in Omega x R which has no radial limits at (0, 0) is an element of partial derivative D such that gamma is bounded away from 0 and pi ...
We and others recently observed that heparin, and more generally GAG, can prevent or cure experimental diabetic nephropathy (19,20,21,27,28). This study demonstrates that chronic GAG/mH treatment of long-term (12 mo) diabetic animals prevents albuminuria, glomerular increases in PAS staining, collagen III accumulation, and, as shown in earlier studies, enhanced collagen α1 (IV) accumulation and synthesis and basement membrane thickening (20,21). Together, these data demonstrate that the treatment ameliorates the functional and structural renal changes associated with diabetes mellitus.. To investigate the molecular mechanisms of the inhibitory effects of GAG, renal TGF-β1 expression was studied. In accordance with a previous study of short-term diabetic rats (29), increased glomerular and tubular expression of TGF-β1 mRNA was observed for our long-term diabetic animals. TGF-β1 protein levels were also increased in many cortical tubules of diabetic animals. However, we observed no significant ...
We construct examples of nonparametric surfaces z = h(x, y) of zero mean curvature which satisfy contact angle boundary conditions in a cylinder in R3 over a convex domain with corners. When the contact angles for two adjacent walls of the cylinder differ by more than −2 , where 2 is the opening angle between the walls, the (bounded) solution h is shown to be discontinuous at the corresponding corner. This is exactly the behavior predicted by the Concus-Finn conjecture. These examples currently constitute the largest collection of capillary surfaces for which the validity of the Concus-Finn conjecture is known and, in particular, provide examples for all contact angle data satisfying the condition above for opening angles 2 2 ( /2 ...
The capillary refill time is an assessment tool well known to us all and routinely used to evaluate circulatory status. Prolonged refill time is suggestive of poor peripheral perfusion but can be affected by many other factors including environment, lighting, temperature and technique. Recommended sites include the fingertip and sternum (Advanced life support group, the resuscitation council, NICE) with the standard technique being to press firmly 5 s and then measure the time taken for the skin to return to a normal colour with normal being less than 2 s. Crook and Taylor investigate the agreement between fingertip and sternum in 92 children who are well, controlling for other variable as listed above. The results are of interest: finger tip refill time (mean 1.08, range 0.05-2.78) is faster than sternum refill time (mean 1.5, range 0.85-2.38). Interestingly there was no relationship (in individuals) between sternum and finger tip capillary refill time-the detailed statistics are in the ...
We aimed to assess the relationship between the clinical and biochemical parameters of perfusion and superior vena cava (SVC) flow in a prospective observational cohort study of very low birth weight (VLBW) infants. Newborns with congenital heart disease were excluded. Echocardiographic evaluation of SVC flow was performed in the first 24 h of life. Capillary refill time (forehead, sternum and toe), mean blood pressure, urine output and serum lactate concentration were also measured simultaneously. Thirty-eight VLBW infants were examined. Eight patients (21%) had SVC flow less than 40 ml/kg/min. There was a poor correlation between the capillary refill time (in all sites), mean blood pressure, urine output and SVC flow. The correlation coefficient for the serum lactate concentration was r = -0.28, p = 0.15. The median serum lactate concentration was 3.5 (range 2.8-8.5) vs. 2.7 (range 1.2-6.9) mmol/l (p = 0.01) in low flow versus normal flow states. A serum lactate concentration of ,2.8 was 100% ...
Results: We suggest using capillary refill time, skin mottling scores and skin temperature gradients; suggest a passive leg raise test to guide fluid resuscitation; recommend crystalloid solutions as the initial fluid of choice; recommend initial fluid resuscitation with 30 ml/kg in the first 3 h, but with extreme caution in settings where there is a lack of mechanical ventilation; recommend against an early start of vasopressors; suggest starting a vasopressor in patients with persistent hypotension after initial fluid resuscitation with at least 30 ml/kg, but earlier when there is lack of vasopressors and mechanical ventilation; recommend using norepinephrine (noradrenaline) as a first-line vasopressor; suggest starting an inotrope with persistence of plasma lactate >2 mmol/L or persistence of skin mottling or prolonged capillary refill time when plasma lactate cannot be measured, and only after initial fluid resuscitation; suggest the use of dobutamine as a first-line inotrope; recommend ...
Dehydration is associated with the leading causes of morbidity and mortality in children throughout the world.1 Nurses in various clinical contexts must routinely assess the hydration status of paediatric patients. Identifying the best indicators or combinations of indicators of childrens hydration status will enable practitioners to optimise patient management and minimise unnecessary procedures.. The review by Steiner et al gives credence to the use of some clinical signs when assessing childrens hydration status. Although the authors did a thorough literature search, most of the 13 included studies had low methodological quality (unblinded non-independent comparison of tests with a valid gold standard in a selected sample of patients). The findings are current best evidence but should still be viewed with some caution.. The findings are relevant to paediatric practitioners in both outpatient and inpatient settings. The review indicates that current assessment of hydration is extremely ...
For an 1100 pound horse horse, 5% dehydration would mean the horse has lost about 55 pounds of water or about 6.875 gallons (1 gallon = 8 pounds of water). At 12% dehydration, the 1100 pound horse has lost 132 pounds of fluid or about 16.5 gallons.. You may also see loss of performance and visual signs without doing these tests. I see this in the arena when I am judging, particularly during the hot humid conditions. I confess I have experienced some of the same symptoms when judging a long horse show while wearing a coat and tie! It takes me about 24 hours to rehydrate!. If you are not familiar with the pinch test or capillary refill time, it is a good idea to discuss these tests with your veterinarian as these are important quick tests to check the status of your horse as a part of general first aid along with being able to check pulse and heart rate. In general terms, the skin pinch test is best done over the shoulder or over the back. Capillary refill time can be checked by pressing on the ...

Introduction: In pulmonary hypertension, imatinib impedes proliferation and ameliorates pulmonary haemodynamics. However, the relaxant potential of imatinib is virtual unknown. Aims and objectives: We wanted to elucidate whether and how imatinib may modulate the tone of pulmonary arteries (PAs) and pulmonary veins (PVs). Methods: Imatinib-induced relaxation was studied by videomicroscopy in precision-cut lung slices (PCLS) from humans and guinea pigs (GPs); baseline luminal vessel area was defined as 100%. Intracellular cAMP was measured by ELISA and imatinib-induced changes of pre- and postcapillary resistances were studied in the isolated perfused lung (GP). Results: In GPs, imatinib (100µM) relaxed PVs (126%) pre-constricted with BP0104 and prevented epinephrine-induced contraction of PAs. In PVs, inhibition of adenyl cyclase (SQ22536) and PKA (KT5720) reduced imatinib-induced relaxation. Conversely, imatinib increased cAMP. Further, inhibition of KATP-channels (glibenclamide), ...
This paper quantifies the structural capacity of the transport steps for oxygen, glucose and fatty acids from the blood in capillaries to the cytosol of muscle cells and compares it with maximal rates of oxygen and substrate transport measured in the same animals and reported in the preceding papers of this series. Dogs have relatively more muscle per unit body mass than goats (37 versus 26%), but the maximal rate of oxidation per gram of muscle is still larger in the dog by a factor of 1.55. The maximal rates of substrate supply from the circulation are similar in both species. We predict that these differences in physiological parameters should be matched by proportional differences in structural capacity. We find that capillary volume and surface area are matched to maximal oxygen demand.

Mental training is important for any sport. Your horse should be willing and responsive under saddle and MUST have good ground manners to successfully participate in distance riding events. Good training is as important as good conditioning, because a horse can use up a lot of physical energy coping with emotional stress at the event. Not to mention that vets don&rsquo t appreciate being kicked!. Practise all the things the vet will do at a ride on a regular basis (like the Horse Health Check). Trot out in hand, straight lines and trot large circles with your horse in both directions. Encourage your horse to stand quietly for vetting. Ask others at your barn to pretend they are the vet and touch your horse all over, listen for gut sounds, take pulse, do capillary refill test, etc. Does your horse tie to the trailer? Does your horse respect portable electric fencing? Does your horse behave around other strange horses in close proximity? Do YOU have good manners (i.e. know about trail ...
The Buckley-Leverett partial differential equation has long been used to model two-phase flow in porous media. In recent years, the PDE has been modified to include a rate-dependent capillary pressure constitutive equation, known as dynamic capillary pressure. Previous traveling wave analysis of the modified Buckley-Leverett equation uncovered non-classical solutions involving undercompressive shocks. More recently, thermodynamically constrained averaging theory (TCAT) has generalized the capillary pressure equation by including additional dependence on fluid properties. In this paper, the model and traveling wave analysis are updated to incorporate TCAT capillary pressure as a generalization of dynamic capillary pressure. Solutions of the corresponding Riemann problem are similar to previous results except in the physically relevant situation in which both phases are pure fluids. The results presented here shed new light on the nature of the interface between one pure fluid displacing another ...

By Wendy Talbot on 16 March 2018. Wondering how to assess the colour of your horses mucous membranes? Your horses mucous membranes (gums) should be moist and a healthy salmon pink colour.. The capillary refill time of your horses gums will give you an indication of the efficiency of his circulation.. How to do it. To assess the colour your horses mucous membranes make sure you are in a well-lit area or use a torch because colour can be very deceptive in poor light. To assess the capillary refill time, vigorously press one finger on the gum above the top front teeth and remove it quickly - it should take no more than two seconds for the area to turn from white back to pink.. Watch our video on how to assess the colour of your horses mucous membranes (courtesy of brookfarmstables). ...
Powell and Jeavons undertook a hospital-based audit(1) comparing the new guidelines for identifying paediatric sepsis(2) to previous cases that had attended the emergency department. By contrast, our recent sepsis audit investigating the assessment of under 5s with fever ≥37.5°C (before possible referral to hospital) was done in primary care. The National Institute for Health and Care Excellence (NICE) guidelines for sepsis assessment outlines four signs that should be recorded: temperature, pulse, respiratory rate and capillary refill time. An initial audit looking at compliance to these guidelines was conducted looking at data in computerised records from May 2014 - May 2018 at an inner-city general practice. Results showed that in only 15% of 111 consecutive consultations with feverish children aged ,5 were all four signs recorded. More specifically, pulse was recorded in 81%, respiratory rate in 49%, and capillary refill time in only 32% of consultations. Following presentation of these ...
In this study, we found a poor correlation between naked-eye assessment of the CR time and qCR time measures in both laymen and clinical staff. Further, we observed poor naked-eye intra-observer repeatability and interobserver agreement by clinical staff in their assessment of CR time. The use of a categorical evaluation of time measurement did not improve agreement between naked-eye estimations and machine-derived classifications.. It is self-evident to most clinicians that different observers, not only in regard to the CR test, often disagree in clinical assessments based on naked-eye observation.24 Previous studies on the reliability of the CR test have partially addressed this by showing a lack of interobserver agreement, but neither performance on the task to actually determine return to normal skin colour, nor the intra-observer repeatability for a group of observers on a standardised set of cases has been assessed previously.11 28 29.

Use of Capillary Pressure Data and Log Calculated Water Saturation for the Characterization of Dual Porosity, Dual Permeability Systems. This paper describes a simple method to divide the effective porosity values that can be calculated from log analysis into two flow media (fracture and matrix) pore volumes for use in numerical simulation models. The division of the porosity is based on the assumption that the total porosity of the system is made up from two contributing rock types or lithofacies that have distinct pore size and/or pore size distribution such that they can be represented by different capillary pressure functions. This assumption is applicable to the non-fractured as well as to the fractured systems.. When the method is used for the fractured systems, the fracture is typically represented by a zero capillary pressure value (gravity segregation). The matrix has its own laboratory measured capillary pressure curve. Based on a predetermined water-hydrocarbon contact and using the ...
A capillary gate mechanism regulates flow resistance efficiently, because pressures, flows, and turbulence are minimal in capillaries, and capillary surface area is greater than that of all larger vessels combined.(1-5) Sympathetic nervous activity releases von Willebrand Factor (VWF) from the capillary endothelium; VWF increases factor VIII activity, which generates insoluble fibrin in the capillary lumen to increase flow resistance (aka viscosity, or systemic vascular resistance). Parasympathetic nervous innervation releases nitric oxide (NO) from the capillary endothelium, which binds to Ca+, inhibits thrombin, accelerates the disintegration of insoluble fibrin, and reduces flow resistance (aka nitrergic neurogenic vasodilation) Hypoxia and hypercarbia open the capillary gate by releasing nitric oxide from the capillary endothelium.(6) The capillary gate mechanism governs cardiac output, cardiac efficiency, tissue perfusion, tissue oxygenation, and organ function. Its activity affects the ...
The following investigation focuses on the impact of capillary pressure on estimation of two phases relative permeability curves. Accurate relative permeability is a crucial parameter for evaluating reservoir performance. The unsteady state core flooding tests, which is considered in this study, is mostly used to measure oil-water relative permeabilities. The Johnson ,Bossler and Neumann (JBN) method is the conventional method for estimating relative permeabilities from field core. The limitations in the JBN method create an error in relative permeability curves and make it unrepresentative of a typical core flooding test results. There are always capillary pressure effects taking place during core flood tests. Ignoring of capillary pressure by JBN method will influence the calculation of relative permeability curves and final saturation levels. One dimensional numerical model with uniform initial saturation has been implemented in this study using Eclipse 100 software to understand the ...
Abstract (EN): The approach to residual oil saturation during the immiscible displacement of oil as predicted by the multiphase Darcy equations is studied. It is well known that when the capillary pressure term is neglected, one arrives at the Buckley-Leverett formulation according to which the inlet face attains residual oil saturation instantaneously. This result may, however, be strongly influenced by the inclusion of the capillary pressure term. In this paper it is shown that when the relative permeability and capillary pressure functions have power law dependencies on the saturation deviation from residual oil condition, the long time solution exhibits a power law decay toward residual saturation. Moreover, the power law decay solution is found to be unique and independent of the initial condition. The relationship of this solution to the classical Buckley-Leverett result is shown. Finally, generalization to the time varying flow rate case is addressed. As a verification of the theoretical ...
The objective of this research is to develop and test a new concept for predicting permeability from routine rock properties. First, we develop a model predicting permeability as a function of capillary pressure. Our model, which is based on the work by Purcell, Burdine and Wyllie and Gardner models, is given by: (Equation 1 - See PDF) Combining the previous equation and the Brooks and Corey model for capillary pressure, we obtain: (Equation 2 - See PDF) The correlation given by this equation could yield permeability from capillary pressure (and vice-versa). This model also has potential extensions to relative permeability (i.e., the Brooks and Corey relative permeability functions) - which should make correlations based on porosity, permeability, and irreducible saturation general tools for reservoir engineering problems where relative permeability data are not available. Our study is validated with a large range/variety of core samples in order to provide a representative data sample over ...

Perfusion is the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue,[1] usually referring to the delivery of blood to a capillary bed in tissue. Perfusion is measured as the rate at which blood is delivered to tissue,[2] or volume of blood per unit time (blood flow) per unit tissue mass. The SI unit is m3/(s·kg), although for human organs perfusion is typically reported in ml/min/g.[3] The word is derived from the French verb perfuser meaning to pour over or through.[4] All animal tissues require an adequate blood supply for health and life. Poor perfusion (malperfusion), that is, ischemia, causes health problems, as seen in cardiovascular disease, including coronary artery disease, cerebrovascular disease, peripheral artery disease, and many other conditions. Tests verifying that adequate perfusion exists are a part of a patients assessment process that are performed by medical or emergency personnel. The most common methods include evaluating a ...

There are many causes for feline dehydration: vomiting and/or diarrhea, heatstroke, an illness causing the cat to stop eating, excessive urination caused by medical conditions such as renal failure and diabetes, lacking clean, fresh water, blood loss, shock or fever.. There are three classes of dehydration which ascertains the severity of the condition: 1. Mild dehydration - up to 5%, moderate dehydration - between 5 and 10% and severe dehydration - 10% or more.. Symptoms of dehydration include poor skin elasticity, lethargy, increased heart rate, sunken eyes, dry, sticky gums, insufficient capillary refill time and constipation. The colon resorbs fluids. If the cat is dehydrated, the body will withdraw water from the stool in an attempt to conserve water which causes constipation.. Its relatively easy to determine whether your kitty is dehydrated. Check your cats skin elasticity by grasping some skin at the scruff of the neck and gently pull it up. If the skin snaps back immediately the cat ...

This paper describes laboratory equipment and procedures aimed at determining drainage gas-oil capillary pressure functions under reservoir conditions. Two series of capillary drainage tests (porous plate method) were performed with sandstone core samples using binary mixtures of methane/n-heptane at different equilibrium pressures, leading to very wide variations in the gas-liquid interfacial tension (IFT) values. Measurements were performed first without connate water (two-phase conditions) and then in the presence of connate water saturation (three-phase conditions). This study has shown that the gas-oil capillary pressures measured at different levels of IFT and without connate water can be transformed into one capillary pressure function, Pc/IFT, down to IFT = 3.7 mN/m. Below this value, the capillary pressures measured were significantly lower than those estimated by the Young-Laplace equation. In the presence of connate water, the gas-oil capillary pressures were always higher than the ...
I have been following the stent scandals and controversies very closely in your paper. I treat diabetics among whom the incidence of coronary heart disease and heart attacks is very high. Most long-term diabetics will need a consultation with a cardiologist sometime during their life, either to prevent heart attacks or to treat one that has already happened.
photo from apassionforscience.pbworks.comDiabetes is one of the most common lifestyle-related diseases. Almost half of the patients we will encounter, regardless of the medical field, will have this medical condition. Our mentors have repeatedly reminded that the symptoms to look out for potential diabetic patients are the three Ps: Polyphagia, Polydipsia, Polyuria. However, the symptoms of diabetics are certainly not limited to these common symptoms. Most of patients that I have encountered have stated the following symptoms:Chills that are usually associated with hypoglycemiaDizziness or lightheadedness (usually with hypoglycemia)Numbness all over the body that are usually associated with hyperglycemiaInability to recognize faces/ slow cognition (usually with hyperglycemia)Dry lips/ mouthDry tongue with abrasive feeling (as if there is salt) when the tongue makes contact with the floor of the mouthNumb hands and feet or tingling sensation over these areas (for long-term diabetics)It would be better
Abstract. Briggs (1897) deduced capillary flow from deviation of the equilibrium between capillarity and gravity. Richards (1931) raised capillary flow to an unproven soil hydrological dogma. Apparent corrections of the dogma led to non-equilibrium flow, macropore flow, and preferential flow during infiltration. Viscous flow is proposed as alternative to capillary flow during unsaturated infiltration.. ...
