Capillary Resistance
Electrophoresis, Capillary
Drug Resistance
Diminished or failed response of an organism, disease or tissue to the intended effectiveness of a chemical or drug. It should be differentiated from DRUG TOLERANCE which is the progressive diminution of the susceptibility of a human or animal to the effects of a drug, as a result of continued administration.

Myosins
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.

Bacteria
One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.

Gases
The vapor state of matter; nonelastic fluids in which the molecules are in free movement and their mean positions far apart. Gases tend to expand indefinitely, to diffuse and mix readily with other gases, to have definite relations of volume, temperature, and pressure, and to condense or liquefy at low temperatures or under sufficient pressure. (Grant & Hackh's Chemical Dictionary, 5th ed)
Disease Reservoirs
Animate or inanimate sources which normally harbor disease-causing organisms and thus serve as potential sources of disease outbreaks. Reservoirs are distinguished from vectors (DISEASE VECTORS) and carriers, which are agents of disease transmission rather than continuing sources of potential disease outbreaks.

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. <<<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.

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)

Arterioles10
- Blood flows from the heart through arteries , which branch and narrow into arterioles , and then branch further into capillaries where nutrients and wastes are exchanged. (wikipedia.org)
- There are two types of capillaries: true capillaries, which branch from arterioles and provide exchange between tissue and the capillary blood, and metarterioles , found only in the mesenteric circulation. (wikipedia.org)
- Lymphatic capillaries are slightly larger in diameter than blood capillaries, and have closed ends (unlike the blood capillaries open at one end to the arterioles and open at the other end to the venules). (wikipedia.org)
- There are two types of capillaries: true capillaries, which branch from arterioles and provide exchange between tissue and the capillary blood, and sinusoids , a type of open-pore capillary found in the liver , bone marrow , anterior pituitary gland , and brain circumventricular organs . (wikipedia.org)
- Capillaries and sinusoids are short vessels that directly connect the arterioles and venules at opposite ends of the beds. (wikipedia.org)
- However, the relationship between CBF and events at the level of the penetrating arterioles and capillaries is not well established. (pnas.org)
- Our data suggests that from young to middle-age, a well-regulated capillary oxygen supply maintains the oxygen availability in cerebral tissue, despite decreased tissue pO 2 next to arterioles. (nature.com)
- The molecular cornerstone of this mechanism is the capillary endothelial cell inward rectifier K + (Kir2.1) channel, which is activated by neuronal activity-dependent increases in external K + concentration, producing a propagating hyperpolarizing electrical signal that dilates upstream arterioles. (pnas.org)
- This anatomical arrangement ideally positions capillaries to detect neuronal activity and communicate it to upstream arterioles. (pnas.org)
- Notable in this context, we recently reported that increases in extracellular K + concentration ([K + ] o ), such as those evoked by neuronal activity, trigger an ascending hyperpolarizing signal that dilates upstream arterioles and enhances capillary red blood cell (RBC) flux and cerebral blood flow ( 3 ). (pnas.org)
Hydrostatic pressure3
- 0.05) that moderated capillary hydrostatic pressure to override direct effects of inhibition of prostaglandin synthesis on permeability. (openrepository.com)
- What exerts a large effect on capillary HYDROSTATIC pressure? (brainscape.com)
- During hyperemia, the coronary artery pressure distal to the stenosis decreases, leading to capillary derecruitment to maintain a constant capillary hydrostatic pressure ( 2 ). (onlinejacc.org)

Skeletal muscle8
- Insulin has vascular actions within the skeletal muscle microcirculation (capillary recruitment) that enhance its own access and that of glucose to the muscle cells. (edu.au)
- It is concluded that progressive resistance training results in significant increases in muscle strength and alters skeletal muscle composition of subjects with peripheral arterial disease. (nih.gov)
- Background: It is well accepted that skeletal muscle conforms to exercise stimulus by increasing capillary density and angiogenesis, but there is less evidence regarding the effect of resistance training on capillary density in flexor hallucis longus (FHL) and soleus muscle. (iranepf.ir)
- Resistance training recovers attenuated APPL1 expression and improves insulin-induced Akt signal activation in skeletal muscle of type 2 diabetic rats" is published ahead of print in the American Journal of Physiology-Endocrinology and Metabolism . (medicalxpress.com)
- This study tested the hypothesis that increases in skeletal muscle capillary density (CD) also contribute to exercise-induced improvements in whole-body insulin sensitivity (insulin-stimulated glucose uptake per unit plasma insulin [M/I]) independent of other mechanisms. (diabetesjournals.org)
- Skeletal muscle capillary density (CD) is lower in older compared with younger adults ( 1 , 2 ) and is associated with glucose intolerance and lower insulin-stimulated glucose uptake ( 3 - 5 ). (diabetesjournals.org)
- This study examined the effect of local infusion of an NOS inhibitor on skeletal muscle glucose uptake (2-deoxyglucose) and capillary blood flow (contrast-enhanced ultrasound) during in situ contractions in rats. (diabetesjournals.org)
- CONCLUSIONS- NOS inhibition attenuated increases in skeletal muscle glucose uptake during contraction without influencing capillary recruitment, suggesting that NO is critical for part of the normal increase in skeletal muscle fiber glucose uptake during contraction. (diabetesjournals.org)
Arteries6
- They draw blood from elastic arteries and branch into resistance vessels. (healthline.com)
- The cardiovascular system is a closed system of vessels called arteries, veins, and capillaries. (healthline.com)
- It does this through thousands of miles of capillaries between the arteries and the veins. (healthline.com)
- About 50 years later, Malpighi, (and, at about the same time, Leeuwenhoek), discovered that the connection between the smallest branches of the arteries and the veins was not by random cavities between the organs, but by a network of extremely fine vessels - the capillaries, visible only under the microscope. (nobelprize.org)
- This rate was thought to be regulated by the greater or lesser contraction of the small arteries, which convey blood to the capillaries. (nobelprize.org)
- When the small arteries constricted, and offered high resistance, the blood came to flow slowly through all capillaries. (nobelprize.org)
Density6
- There were significant increases in type I and type II fiber areas, and capillary density also increased significantly in the training group. (nih.gov)
- Objectives: In this study, we evaluated the effect of resistance training on capillary density around soleus and FHL muscles in type 1 diabetic rats. (iranepf.ir)
- There was a positive correlation between plasma NO concentration and capillary density in the soleus muscle (R2 = 0.65). (iranepf.ir)
- After middle-age, due to decreased hematocrit, reduced capillary density and higher capillary transit time heterogeneity, the capillary network fails to compensate for larger decreases in arterial pO 2 . (nature.com)
- There are many conditions that are associated with reduced myocardial capillary density (MCD) and, hence, lower CFR, such as myocardial infarction ( 4 ), hypertension ( 5 ), and diabetes ( 6 ). (onlinejacc.org)
- Statistically significant peripapillary capillary vessel density progression was found in 17% of the study eyes, and half of the progressing cases also showed significant and spatially corresponding RNFL thickness progression. (thefreedictionary.com)
Vascular16
- Obesity and insulin resistance are associated with dysregulated vascular function within muscle and a loss of insulin-mediated capillary recruitment. (edu.au)
- Furthermore, agents that impair insulin's vascular actions to recruit capillaries lead to acute insulin resistance in terms of muscle glucose uptake. (edu.au)
- This review examines the mechanisms involved in insulin-mediated capillary recruitment and the vascular defects associated with obesity and insulin resistance that may impair the capillary recruiting process. (edu.au)
- Therefore, we tested whether the superimposition of resistance exercise with whole-body vibration and vascular occlusion (vibroX) would improve these variables in endurance-trained males relative to resistance exercise alone. (uzh.ch)
- CONCLUSIONS: We achieved a proof of concept by demonstrating that modification of resistance exercise by superimposing side-alternating whole-body vibration and sustained vascular occlusion induced further improvements in CP, capillarization and hypertrophy, all of which were not observed with resistance training alone. (uzh.ch)
- The occlusion technique can be used in intact animals and patients for the partitioning of pulmonary vascular resistance (PVR) into an arterial segment (PVRa) and a capillary-venous segment, and for the determination of an effective pulmonary capillary pressure ( P c ) 1 , 2 . (ersjournals.com)
- During early embryonic development [4] new capillaries are formed through vasculogenesis , the process of blood vessel formation that occurs through a de novo production of endothelial cells which then form vascular tubes. (wikipedia.org)
