The formation of clumps of RED BLOOD CELLS under low or non-flow conditions, resulting from the attraction forces between the red blood cells. The cells adhere to each other in rouleaux aggregates. Slight mechanical force, such as occurs in the circulation, is enough to disperse these aggregates. Stronger or weaker than normal aggregation may result from a variety of effects in the ERYTHROCYTE MEMBRANE or in BLOOD PLASMA. The degree of aggregation is affected by ERYTHROCYTE DEFORMABILITY, erythrocyte membrane sialylation, masking of negative surface charge by plasma proteins, etc. BLOOD VISCOSITY and the ERYTHROCYTE SEDIMENTATION RATE are affected by the amount of erythrocyte aggregation and are parameters used to measure the aggregation.

Anemia characterized by a decrease in the ratio of the weight of hemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular hemoglobin concentration is less than normal. The individual cells contain less hemoglobin than they could have under optimal conditions. Hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions. (Stedman, 25th ed; from Miale, Laboratory Medicine: Hematology, 6th ed, p393)

Effect of intravenous dextran 70 and pneumatic leg compression on incidence of postoperative pulmonary embolism. (1/2888)

The incidence of pulmonary embolism and deep vein thrombosis was measured in 50 matched pairs of patients undergoing common surgical procedures with preoperative and postoperative ventilation-perfusion lung scans and the fibrinogen uptake test. One patient in each pair was treated with intravenous dextran 70 and pneumatic leggings. The incidence of pulmonary embolism among the treated patients was significantly reduced from 24% to 8%, but the incidence of deep vein thrombosis was not significantly reduced (34% to 24%).  (+info)

Reduction in baroreflex cardiovascular responses due to venous infusion in the rabbit. (2/2888)

We studied reflex bradycardia and depression of mean arterial blood pressure (MAP) during left aortic nerve (LAN) stimulation before and after volume infusion in the anesthetized rabbit. Step increases in mean right atrial pressure (MRAP) to 10 mm Hg did not result in a significant change in heart rate or MAP. After volume loading, responses to LAN stimulation were not as great and the degree of attenuation was propoetional to the level of increased MRAP. A change in responsiveness was observed after elevation of MRAP by only 1 mm Hg, corresponding to less than a 10% increase in average calculated blood volume. after an increase in MRAP of 10 mm Hg, peak responses were attenuated by 44% (heart rate) and 52% (MAP), and the initial slopes (rate of change) were reduced by 46% (heart rate) and 66% (MAP). Comparison of the responses after infusion with blood and dextran solutions indicated that hemodilution was an unlikely explanation for the attenuation of the reflex responses. Total arterial baroreceptor denervation (ABD) abolished the volume-related attenuation was still present following bilateral aortic nerve section or vagotomy. It thus appears that the carotid sinus responds to changes inblood volume and influences the reflex cardiovascular responses to afferent stimulation of the LAN. On the other hand, cardiopulmonary receptors subserved by vagal afferents do not appear to be involved.  (+info)

Interaction of inflammatory cells and oral microorganisms. II. Modulation of rabbit polymorphonuclear leukocyte hydrolase release by polysaccharides in response to Streptococcus mutans and Streptococcus sanguis. (3/2888)

The release of lysosomal hydrolases from polymorphonuclear leukocytes (PMNs) has been postulated in the pathogenesis of tissue injury in periodontal disease. In the present study, lysosomal enzyme release was monitored from rabbit peritoneal exudate PMNs exposed to Streptocccus mutans or Streptococcus sanguis. S. mutans grown in brain heart infusion (BHI) broth failed to promote significant PMN enzyme release. S. sanguis grown in BHI broth, although more effective than S. mutants, was a weak stimulus for promotion of PMN hydrolase release. Preincubation of washed, viable S. mutans in sucrose or in different-molecular-weight dextrans resulted in the ability of the organisms to provoke PMN release reactions. This effect could bot be demonstrated with boiled or trypsinized S. mutans or with viable S. sanguis. However, when grown in BHI broth supplemented with sucrose, but not with glucose, both S. mutans and S. sanguis triggered discharge of PMN enzymes. The mechanism(s) whereby dextran or sucrose modulates PMN-bacterial interaction may in some manner be related to promotion of microbial adhesiveness or aggregation by dextran and by bacterial synthesis of glucans from sucrose.  (+info)

Glomerular size-selective dysfunction in NIDDM is not ameliorated by ACE inhibition or by calcium channel blockade. (4/2888)

BACKGROUND: In patients with insulin-dependent diabetes mellitus (IDDM) and overt nephropathy glomerular barrier size-selectivity progressively deteriorates with time and is effectively improved by angiotensin converting enzyme (ACE) inhibition. Whether similar glomerular functional changes develop in proteinuric patients with non-insulin-dependent diabetes mellitus (NIDDM), and whether antihypertensive agents can favorably affect glomerular filtration of macromolecules in these patients, has not been documented yet. METHODS: We investigated renal hemodynamics and fractional clearance of neutral dextrans of graded sizes, in nine proteinuric patients with NIDDM and renal biopsy findings of typical diabetic glomerulopathy. Six healthy volunteers served as controls. We also investigated the effects of an ACE inhibitor and of a calcium channel blocker, both given in doses targeted to achieve a comparable level of systemic blood pressure control, on glomerular hemodynamics and sieving function. Theoretical analysis of glomerular macromolecule transport was adopted to evaluate intrinsic glomerular membrane permeability properties. RESULTS: Fractional clearance of large macromolecules (42 to 66 A in radius) was significantly higher in diabetic patients than in controls, and the distribution of membrane pore radii was calculated to be shifted towards larger pore sizes in diabetics (mean radius increased from 55 to 60 A). Despite effective blood pressure control, neither antihypertensive affected glomerular hemodynamics to any significant extent. Fractional clearance of dextrans, as well as of albumin and IgG, and total urinary proteins were not modified by either treatments. CONCLUSIONS: These data indicate that patients with NIDDM and overt nephropathy develop abnormalities in size-selective function of the glomerular barrier and, at variance to IDDM, such changes were not ameliorated either by ACE inhibition or calcium channel blockade.  (+info)

Poly(L-lysine)-graft-dextran copolymer promotes pyrimidine motif triplex DNA formation at physiological pH. Thermodynamic and kinetic studies. (5/2888)

Extreme instability of pyrimidine motif triplex DNA at physiological pH severely limits its use for artificial control of gene expression in vivo. Stabilization of the pyrimidine motif triplex at physiological pH is therefore of great importance in improving its therapeutic potential. To this end, isothermal titration calorimetry interaction analysis system and electrophoretic mobility shift assay have been used to explore the thermodynamic and kinetic effects of our previously reported triplex stabilizer, poly (L-lysine)-graft-dextran (PLL-g-Dex) copolymer, on pyrimidine motif triplex formation at physiological pH. Both the thermodynamic and kinetic analyses have clearly indicated that in the presence of the PLL-g-Dex copolymer, the binding constant of the pyrimidine motif triplex formation at physiological pH was about 100 times higher than that observed without any triplex stabilizer. Of importance, the triplex-promoting efficiency of the copolymer was more than 20 times higher than that of physiological concentrations of spermine, a putative intracellular triplex stabilizer. Kinetic data have also demonstrated that the observed copolymer-mediated promotion of the triplex formation at physiological pH resulted from the considerable increase in the association rate constant rather than the decrease in the dissociation rate constant. Our results certainly support the idea that the PLL-g-Dex copolymer could be a key material and may eventually lead to progress in therapeutic applications of the antigene strategy in vivo.  (+info)

Polymer structure and solubility of deoxyhemoglobin S in the presence of high concentrations of volume-excluding 70-kDa dextran. Effects of non-s hemoglobins and inhibitors. (6/2888)

Earlier observations indicated that volume exclusion by admixed non-hemoglobin macromolecules lowered the polymer solubility ("Csat") of deoxyhemoglobin (Hb) S, presumably by increasing its activity. In view of the potential usefulness of these observations for in vitro studies of sickling-related polymerization, we examined the ultrastructure, solubility behavior, and phase distributions of deoxygenated mixtures of Hb S with 70-kDa dextran, a relatively inert, low ionic strength space-filling macromolecule. Increasing admixture of dextran progressively lowered the Csat of deoxyHb S. With 12 g/dl dextran, a 5-fold decrease in apparent Csat ("dextran-Csat") was obtained together with acceptable sensitivity and proportionality with the standard Csat when assessing the effects of non-S Hb admixtures (A, C, and F) or polymerization inhibitors (alkylureas or phenylalanine). The volume fraction of dextran excluding Hb was 70-75% of total deoxyHb-dextran (12 g/dl) volumes. Electron microscopy showed polymer fibers and fiber-to-crystal transitions indistinguishable from those formed without dextran. Thus when Hb quantities are limited, as with genetically engineered recombinant Hbs or transgenic sickle mice, the dextran-Csat provides convenient and reliable screening of effects of Hb S modifications on polymerization under near-physiological conditions, avoiding problems of high ionic strength.  (+info)

Cytokine-mediated inflammatory hyperalgesia limited by interleukin-4. (7/2888)

1. The effect of IL-4 on responses to intraplantar (i.pl.) carrageenin, bradykinin, TNFalpha, IL-1beta, IL-8 and PGE2 was investigated in a model of mechanical hyperalgesia in rats. Also, the cellular source of the IL-4 was investigated. 2. IL-4, 30 min before the stimulus, inhibited responses to carrageenin, bradykinin, and TNFalpha, but not responses to IL-1beta, IL-8 and PGE2. 3. IL-4, 2 h before the injection of IL-1beta, did not affect the response to IL-1beta, whereas IL-4, 12 or 12+2 h before the IL-1beta, inhibited the hyperalgesia (-30%, -74%, respectively). 4. In murine peritoneal macrophages, murine IL-4 for 2 h before stimulation with LPS, inhibited (-40%) the production of IL-1beta but not PGE2. Murine IL-4 (for 16 h before stimulation with LPS) inhibited LPS-stimulated PGE2 but not IL-1beta. 5. Anti-murine IL-4 antibodies potentiated responses to carrageenin, bradykinin and TNFalpha, but not IL-1beta and IL-8, as well as responses to bradykinin in athymic rats but not in rats depleted of mast cells with compound 40/80. 6. These data suggest that IL-4 released by mast cells limits inflammatory hyperalgesia. During the early phase of the inflammatory response the mode of action of the IL-4 appears to be inhibition of the production TNFalpha, IL-1beta and IL-8. In the later phase of the response, in addition to inhibiting the production of pro-inflammatory cytokines, IL-4 also may inhibit the release of PGs.  (+info)

Heterogeneity in the ability of cytotoxic murine NK cell clones to enhance Ig secretion in vitro. (8/2888)

We recently described a panel of cytotoxic murine NK cell clones that also enhanced Ig secretion by B cells activated in an in vitro model of T cell-independent type 2 (TI-2) responses. We employed dextran-conjugated anti-IgD (alphadelta-dex) as a model antigen. Here we study the mechanism of Ig induction by these clones. Addition of the various NK clones to sort-purified B cells stimulated with alphadelta-dex and IL-2 resulted in a markedly heterogeneous increase in Ig secretion, which varied from 3-fold, as mediated by clone PKO 56, to 15-fold, as induced by clone PKO 101. The other NK cells showed intermediate levels of Ig induction. Furthermore, while addition of as few as 0.04% of PKO 101 cells stimulated significant increases and 1% induced near maximum Ig production, a 3% addition of PKO 56 cells was required for significant enhancement of Ig secretion. Supernatant material collected from the NK clones mediated Ig production at levels that mirrored the induction by the corresponding cells. Cytokine analysis showed that while all members of the NK panel produced IFN-gamma only two secreted granulocyte macrophage colony stimulating factor and that the levels of Ig induction mediated by the NK clones correlated only with their levels of IFN-gamma secretion. Culture of B and NK cells in the presence of anti-IFN-gamma demonstrated that IFN-gamma was the critical cytokine in NK-induced Ig production. These findings establish heterogeneity in the ability of NK cells to increase Ig secretion in vitro and show that NK-produced IFN-gamma is an important factor in determining this heterogeneity.  (+info)

Rapid destruction of hepatocytes after hepatocyte transplantation has hampered the application of this procedure clinically. The instant blood-mediated inflammatory reaction (IBMIR) is a plausible underlying cause for this cell loss. The present study was designed to evaluate the capacity of low molecular weight dextran sulfate (LMW-DS) to control these initial reactions from the innate immune system. Fresh and cryopreserved hepatocytes were tested in an in vitro whole-blood model using ABO-compatible blood. The ability to elicit IBMIR and the capacity of LMW-DS (100 mu g/ml) to attenuate the degree of activation of the cascade systems were monitored. The effect was also compared to conventional anticoagulant therapy using unfractionated heparin (1 IU/ml). Both fresh and freeze thawed hepatocytes elicited IBMIR to the same extent. LMW-DS reduced the platelet loss and maintained the cell counts at the same degree as unfractionated heparin, but controlled the coagulation and complement systems ...

Hemorrhagic shock was induced by removal of up to 50% blood volume over 20 min until mean arterial pressure (MAP) decreased to 35-40 mmHg. Animals were left in shock at 32°C for 60 min. Resuscitation was commenced with small boluss (0.3 ml or ~3% of shed blood) injected into the femoral vein and Lead II ECG, MAP and heart rate (HR) were monitored.. Results: 0.3 ml of 7.5% saline at resuscitation led to a drop in MAP to about 10 mmHg lasting for 4 min, increased to around 60 mmHg and then slowly declined to 40 mmHg over the next hour. No arrhythmias were detected. Curiously, 0.3 ml of 7.5% NaCl/6% Dextran-70 led to a 1.5 fold increase in the QRS amplitude, ventricular arrhythmias and cardiac instability after 10 min, and an increase in HR of 20 to 40 bpm. The MAP initially fell then quickly returned to 35-38 mmHg for ~4 min, increased to above 55 mmHg and stabilized at around 50 mmHg for 60 min. 0.3 ml of 7.5% NaCl/10% hetastarch resulted in a 63% mortality (5 of the 8 rats died from ...

Although hydroxyapatite is commonly used as a scaffold for bone regeneration, sponges may be suitable because of the adaptability to the defect. To use as a scaffold, the fiber of sponge would be coated with any adhesive to storage stem cells in the sponges. Fiber in the structure of commercially available sponges was coated by immersion in dextran solution and air dried. After seeding of rat bone marrow cells (rBMCs), the sponges were implanted subcutis of rats for estimate osteogenesis in vivo. The level of osteocalcin was 25.28 ± 5.71 ng/scaffold and that of Ca was 129.20 ± 19.69 μg/scaffold. These values were significantly high- er than those in sponges without dextran coating (p < 0.01). It was thought that rBMCs could be stored on the shelf by dextran deposition in the fiber of the sponge. In vivo examination, dextran induced osteogenesis by rBMCs in many spaces in the inner structure of the sponge.

Cámara CL & N Wilke, Chem. Phys. Lipids, 2017 Polysaccharides have been associated with various biological functions through their binding to membranes, but their specific role is still under debate. The aim of this work was to study the interaction of cationic and anionic polysaccharides with anionic and zwitterionic monolayers, at different subphase compositions, thus analyzing the influence of electrostatics on the interaction. The consequent effect of the polymer-lipid binding on the film properties was studied, with special interest in monolayer dynamics. The results indicate that electrostatic interactions play an important role in polymer-membrane affinity, and that the polymers formed a sub-layer, which increased the shear viscosity of the interface. The interacting polymer, even when it did not penetrate the lipid film, induced a polymer-like behavior of the monolayer regarding its dynamics: the whole film (polymer+lipid) became very viscous. As a consequence, the dynamic of the ...
The dextran - solutions of the polysaccharides from cultures of several bacteria, their antigenic properties. The dextran may have varying degrees of polymerization and, consequently, different molecular weight; these can be obtained by plasma-substituting solutions for various applications. Solutions containing dextran with a high molecular weight, are used primarily as a means of hemodynamic, but with a lower molecular weight as a corrector of rheological properties of blood. When injected into the blood dextrans increase the oncotic pressure and increase the displacement of fluid from the tissues into the bloodstream. They increase the diuresis and thus the detoxification processes. Because in the body the partial hydrolysis of the dextrans are excreted mainly by the kidneys (renal failure is a limitation to their use ...

Carbohydrates covalently linked with other chemical species are termed glycoconjugates. They are important compounds in biology, and are involved in many processes, such as cell-cell interactions. Glycoconjugates can be prepared by conjugating a compound to the reducing end of a carbohydrate directly or by modification of the reducing end by a multifunctional compound which in a second step can be conjugated to other molecules. Chemically modified glycoconjugates with carbohydrates conjugated to multifunctional compounds, could provide a vast amount of possibilities for further conjugation, opening up for constructing novel biopolymer hybrid molecules, for example polysaccharide block copolymers.. The aim of this work was to investigate the suitability of two types of bifunctional molecules in ligations to the carbonyl group at the reducing end of dextran oligosaccharides, and thereby activating the dextran for further conjugation.. Dextran was first partially degraded by acid hydrolysis to ...
Dextran is a glucan compound that is used in skin care products. Comprised of polysaccharide and glucose, its medicinal purposes include acting as an antithrombotic, reducing blood viscosity. A polysaccharide is a system of polymeric carbohydrate molecules comprised of long chains bound by sugar molecules. The ingredient has been found to deliver water-binding activity for the skin as well as several other benefits.. Louis Pasteur discovered Dextran as an antimicrobial product. Antimicrobials kill microorganisms and inhibit their growth. The glucan, which also has been used to reduce blood thickness, was listed by the World Health Organization as a Model Essential Medicine, a list of medicines that are considered to be necessary for basic health systems.. In healthcare, Dextran has many different uses. In surgery, the compound is used to reduce vascular thrombosis. It is also used for binding platelets. Dextran has also been used in eye drops, IV solutions, for binding, and to prevent oxidation ...

As previously shown (16-19), direct induction of apoptosis by Rituximab is very ineffective unless the antibody is hyper-cross-linked by secondary antibody or immobilized on plastic. The goal of the present work was to determine if higher valency preparations of Rituximab could be used to simulate hyper-cross-linking events using formulations that are applicable in vivo. This goal was achieved by the generation of a polymer of Rituximab that consisted of ∼5 immunoglobulins per dextran molecule. To show its potency in vitro and in vivo, the polymer preparation was compared with Rituximab monomer and with a previously published dimer (30), which showed some improved activity when tested in apoptosis assays. Our results clearly showed that the polymer is able to induce apoptosis of CD20+ human lymphoma cell lines directly on binding, distinguishing it from both the monomer and dimer preparations using the TUNEL assay (Rituximab, 3%; dimer, 3%; polymer, 58%; see Figs. 1B and 2B). These findings ...
Nucleosides like adenosine, uridine and their nucleotide derivatives (e.g. ATP and UTP) play important roles in many cellular functions, sometimes by acting as signalling molecules through binding to specific P2 nucleotide receptors. P2 receptors are subdivided into P2X and P2Y subfamilies, the latter of which are G-protein coupled receptors. P2Y receptors and nucleoside transporters have been detected in human and rat lungs, where they mediate effects of interest in airway diseases. The aim of this study was to investigate whether uridine has any anti-inflammatory properties in an asthma-like animal model of lung inflammation.. The Sephadex-induced lung inflammation model in Sprague-Dawley rats was chosen mainly due to its localised inflammatory response and uridines limited oral bioavailability. The dextran beads, with or without the addition of uridine, were instilled intratracheally into the lungs, which were excised and examined after 24 h.. Sephadex alone led to massive oedema and ...
Many pathologies are characterized by poor blood vessel growth and reduced nutrient delivery to the surrounding tissue, introducing a need for tissue engineered blood vessels. Our lab has developed a 3D co-culture method to grow interconnected networks of pericyte-invested capillaries, which can anastamose with host vasculature following implantation to restore blood flow to ischemic tissues. However, if the engineered vessels contain endothelial cells (ECs) that are misaligned or contain wide junctional gaps, they may function improperly and behave more like the pathologic vessels that nourish tumors. The purpose of this study was to test the resistance to permeability of these networks in vitro, grown with different stromal cell types, as a metric of vessel functionality. A fluorescent dextran tracer was used to visualize transport across the endothelium and the pixel intensity was quantified using a customized MATLAB algorithm. In fibroblast-EC co-cultures, the dextran tracer easily penetrated
Typically employed for tissue sections, in vivo neurons, and cultured cells, 3,000 MW dextrans are used to trace fine neuron projections and investigate gap junctions; 10,000 MW dextrans have slower distribution and longer cellular retention and do not cross gap junctions. The staining pattern produced by most of these labeled dextran products is lysine fixable.
Figure 8: Imaging of phagocytic cells with iron oxide-enhanced MR imaging. (A) USPIO and DOTA-Gd-enhanced MR imaging of EAE rats. A periventricular lesion shows DOTA-Gd enhancement but not USPIO uptake. Vice versa, a ventral lesion shows USPIO uptake but no DOTA-Gd enhancement. No enhancement is seen in a control animal. (B) Pre-Gd T2 MRI on a MS patient demonstrates multiple lesions, and while there is a DTPA-Gd and USPIO enhancing lesions (arrow), there also is an USPIO-uptake-only lesion (arrowhead). (C) Spatiotemporal profile of USPIO uptake in the ischemic rat brain over 7 days. While USPIO uptake is first seen in the periphery of the infarct (ADC map), uptake becomes more central on the following days, while no uptake is seen on day 7. (D) Comparison of USPIO and DTPA-Gd in a patient with ischemic stroke. Diffusion-weighted imaging displays ischemic area. Areas of USPIO uptake are clearly different from gadolinium enhancement.

本研究探討傾斜式掃流薄膜超過濾系統中,在不同操作條件(氣體流速,液體流速,進料濃度,透膜壓差)下,改變傾斜角度對濾速的影響。實驗系統為管型無機薄膜超過濾模組,測試之巨分子溶液為dextran T500之水溶液。在單一液相超過濾系統中,改變傾斜角度對於超過濾濾速的影響並不大,而在氣液兩相超過濾系統中,改變傾斜角度對於濾速有較顯著的提升。實驗結果發現,濾速大小與傾斜角度關係,依序為45度,60度,30度,90度(垂直)及0度(水平)。在低液體流速,高氣體流速,高進料濃度或高透膜壓差下,改變傾斜角度,濾速值有較明顯之變化。再者,經由對傾斜角度做較小角度之調整,發覺當傾斜角度為50度時,其濾速實驗值最大,顯示傾斜超過濾系統中,有一最佳之傾斜角度。
In the present study, the production of dextran from date extract and sucrose as carbon sources by the bacterium Leuconostoc mesenteroides NRRL B512 (f) was investigated. In comparison to blue dextran (Mw≈2000 Da), dextran molecular weight was reduced (Mw2000 KDa). Flow behavior indices of dextran solutions from date extracts were investigated and rheological parameters were evaluated at concentrations of 1.5, 2.5, 5, together with 10% total solids at 25˚C using a Brookfield rotational viscometer as well as a cone and plate geometry. The experimental results followed the power law model for the best fit and the values of flow behavior index (n) were less than unity (0.49 .93) at all concentrations, revealing the shear thinning nature of the produced dextran. Furthermore, dependence of apparent viscosity on concentration was confirmed using the power law model.
In this study, the release of recombinant human interleukin-2 (rhlL-2) from methacrylated dextran (dex-MA) and (lactate-)hydroxyethyl methacrylated dextran (dex-(lactate-)HEMA) hydrogels with varying crosslink density was investigated. Hydrogels derived from dex-MA are stable under physiological conditions (pH 7 and 37degreesC), whereas dex-HEMA and dex-lactate-HEMA hydrogels degrade due to the presence of hydrolytically sensitive esters in the crosslinks of the gels. The protein release profiles both the non-degradable and degradable dextran-based hydrogels showed that with increasing crosslink density of the get, the release of rhIL-2 decreases. From dex-MA hydrogels with an initial water content above 70%, the rhIL-2 release followed Fickian diffusion, whereas from gels with an initial water content of 70% or lower the protein was fully entrapped in the hydrogel meshes. In contrast with non-degradable dex-MA hydrogels, degradable dex-lactate-HEMA gels with comparable network characteristics ...

KUHNERT, Diane C.; GILDENHUYS, Samantha y DIRR, Heini W.. Effect of macromolecular crowding on the stability of monomeric glutaredoxin 2 and dimeric glutathione transferase A1-1. S. Afr. j. sci. [online]. 2008, vol.104, n.1-2, pp.76-80. ISSN 1996-7489.. The effect of macromolecular crowding on the structure and stability of monomeric glutaredoxin 2 (Grx2) and its homodimeric structural homologue human glutathione transferase A1-1 (hGST A1-1) was investigated using dextran 70 as crowding agent. Far-UV circular dichroism and fluorescence spectroscopic data indicated that repulsive steric interactions between the proteins and dextran (50-300 mg/ml) had little effect on the global structures of the native proteins. Urea-induced unfolding of both proteins was reversible (recoveries of ,80%) at low dextran concentrations (,100 mg/ml) but resulted in significant losses in refolding recoveries at higher levels of dextran, due to aggregation. The two-state global unfolding processes of Grx2 and hGST ...
High-molecular weight dextran is a plasma volume expander made from natural sources of sugar (glucose). It works by restoring blood plasma lost through severe bleeding. Severe blood loss can decrease oxygen levels and can lead to organ failure, brain damage, coma, and possibly death. Plasma is needed to circulate red...
We next probed expansion of the fusion pore with tracers of various molecular sizes (12). The smaller molecules, SRB (∼1.4 nm) and 3-kD dextran (∼4 nm), permeated earlier than did 10-kD dextran (∼6 nm), whereas 70-kD dextran (∼12 nm) permeated later (Fig. 4B, C, and E). As expected, two 10-kD dextran tracers permeated simultaneously (Fig. 4D). The observation that the larger tracers began to permeate abruptly after the smaller tracers suggests that the expanding pore has a well-defined geometry. Moreover, closure of the SRB-permeable pore was detected without opening of the 10-kD dextran-permeable pore in 7% (11/164) of SRB events, which were characterized by smaller increases in SRB fluorescence (12) that ceased shortly after pore opening (Fig. 4F). Such closure was also detected in 2% (2/84) of 3-kD dextran events before 10-kD dextran events, but not in 10-kD dextran events before 70-kD dextran events (n = 62). Thus, the fusion pore was semistable when the pore diameter was between 1.4 ...
In this work, intramolecular and intermolecular associations under the effect of shear flow of dilute aqueous alkaline solutions of dextan, hydroxyethylcellulose (HEC), and the hydrophobically modified analogue (HM-2-HEC) in the presence of a chemical cross-linking agent were characterized with the aid of viscometry and rheo-small angle light scattering (rheo-SALS) methods. The picture that emerges at short times during the cross-linking reaction at a constant shear rate is that HEC coils contract because of intramolecular cross-linking; whereas the HM-2-HEC species show an incipient association and the dextran molecules are unaffected due to their compact structures. At longer times, interchain cross-linking of the polymer promotes the growth of large flocs, which are disrupted by shear forces when they are sufficiently large. The delicate interplay between intramolecular and intermolecular association is governed by factors such as the magnitude of the shear rate, the cross-linking agent ...

A conjugate of polyL-lysine (PLL) with unsulfated dextran produced by reductive amination was found to have remarkable anti-HIV-1 activity against both the macrophage-tropic R5 virus Ba-L and T-cell line tropic X4 virus IIIB strains, although neither PLL nor dextran has such activity. The conjugate is a pseudoproteoglycan (pseudoPG) that simulates the structure of a proteoglycan. Conjugation with dextran was found to produce an antiviral effect in three kinds of assay systems including a human CD4(+) T-cell line, and the pseudoPG synthesized using 10 kDa PLL and 10 kDa dextran showed EC(50) 4-40 times lower than that of sulfated dextran or heparin against Ba-L and EC(50) equal to that against IIIB, indicating that PLL-dextran (PLL-Dex) was more effective against R5 virus than sulfated polysaccharides ...
Methods: Twenty patients undergoing endovascular stenting for abdominal aortic aneurysm were randomized to receive 100 mL of 10% dextran-40. orsalinc, over I hour, during their operation in addition to heparin. Mood samples were taken preoperatively, intraoperatively (immediately after operative procedure), and 24 hours postoperatively. Thrombi were formed in a Chandler loop and used to assess endogenous fibrinolysis over 24 hours, measured as the fall in thrombus weight, and the release of fluorescently labelled fibrinogen from the thrombus. Plasma samples were analyzed for markers of fibrinolysis; plasmin-antiplasmin (PAP), PAI-1, and t-PA, and for functional von Willebrand factor (vWF). Platelet response to thrombin and other agonists was measured by flow cytometry.. Results: S63845 supplier Thrombi formed ex vivo front the intraoperative blood samples from the dextran-treated patients. exhibited significantly greater fibrinolysis vs preoperative samples, seen both as a significantly greater ...

Calcium kinetics and its intracellular mobilization are important in all biological processes. We used verapamil to examine the effect of calcium entry blockade on microvascular transport of macromolecules in ischemia-reperfusion injury. The rat cremaster muscle was splayed, placed in a Lucite intravital chamber, and suffused with bicarbonate buffer. The clearance of fluorescein isothiocyanate-conjugated dextran (FITC-dextran 150) was measured as an index of microvascular transport. After determination of baseline data (clearance of FITC-dextran 150, 3.0 +/- 0.5 microliters/5 min/g), the muscle was made ischemic for 2 hours by clamping its vascular pedicle and subsequently was reperfused for 2 hours. Ischemia-reperfusion produced a marked increase in FITC-dextran clearance. After a peak of 12 +/- 2-fold increase observed in the first 15 minutes into reperfusion, FITC-dextran 150 clearance decreased in magnitude and stabilized at about sixfold above baseline. Verapamil did not change the baseline ...
There are several experimental models describing in vivo eosinophil (EO) migration, including ip injection of a large volume of saline (SAL) or Sephadex beads (SEP). The aim of this study was to investigate the mechanisms involved in the EO migration in these two models. Two consecutive injections of SAL given 48 hr apart, induced a selective recruitment of EO into peritoneal cavity of rats, which peaked 48 hr after the last injection. SEP, when injected ip, promoted EO accumulation in rats. The phenomenom was dose-related and peaked 48 hr after SEP injection. To investigate the mediators involved in this process we showed that BW A4C, MK 886 and dexamethasone (DXA) inhibited the EO migration induced by SAL and SEP. To investigate the source of the EO chemotactic factor we showed that mast cells, macrophages (MO), but not lymphocytes, incubated in vitro in presence of SAL released a factor which induced EO migration. With SEP, only mast cells release a factor that induced EO migration, which was ...
Side Effects for INFED (iron dextran injection) are also known as adverse reactions. Below is a summary of known side effects for INFeD.
Antilevan, antidextran, antiteichoic acid, anti-A and normal γG, all isolated from a single human, as well as pooled γG and γM, were analyzed for amino acid content. Differences ranging from 7 to 32 residues were found among these antibodies in glycine, valine, leucine, tyrosine, arginine, lysine, and threonine content. These conspicuous differences in amino acid composition were not correlated with the Gm type of these antibodies. Hydroxylysine was found in two of the four antibodies, antidextran and antiteichoic acid, and in γM- immunoglobulin. No hydroxylysine was found in γG- globulins. These findings probably account for discrepancies in the literature concerning the occurrence of this residue in antibody protein ...
