Insulin-like growth factors I and II are unable to form and maintain their native disulfides under in vivo redox conditions. (1/706)

Insulin-like growth factor (IGF) I does not quantitatively form its three native disulfide bonds in the presence of 10 mM reduced and 1 mM oxidized glutathione in vitro [Hober, S. et al. (1992) Biochemistry 31, 1749-1756]. In this paper, we show (i) that both IGF-I and IGF-II are unable to form and maintain their native disulfide bonds at redox conditions that are similar to the situation in the secretory vesicles in vivo and (ii) that the presence of protein disulfide isomerase does not overcome this problem. The results indicate that the previously described thermodynamic disulfide exchange folding problem of IGF-I in vitro is also present in vivo. Speculatively, we suggest that the thermodynamic disulfide exchange properties of IGF-I and II are biologically significant for inactivation of the unbound growth factors by disulfide exchange reactions to generate variants destined for rapid clearance.  (+info)

Activation of Xenopus eggs by proteases: possible involvement of a sperm protease in fertilization. (2/706)

Egg activation in cross-fertilization between Xenopus eggs and Cynops sperm may be caused by a protease activity against Boc-Gly-Arg-Arg-MCA in the sperm acrosome. To determine the role of the sperm protease in fertilization, the protease was purified from Cynops sperm using several chromatographic techniques. We found that purified sperm protease readily hydrolyzes Boc-Gly-Arg-Arg-MCA and Z-Arg-Arg-MCA, that protease activity was inhibited by the trypsin inhibitors aprotinin and leupeptin, and that not only the purified protease, but also cathepsin B, induces activation in Xenopus eggs. We inseminated unfertilized Xenopus eggs with homologous sperm in the presence of various peptidyl MCA substrates or protease inhibitors and demonstrated that trypsin inhibitors or MCA substrates containing Arg-Arg-MCA reversibly inhibited fertilization of both fully jellied and denuded eggs. Sperm motility was not affected by the reagents. An extract obtained from Xenopus sperm showed hydrolytic activity against Boc-Gly-Arg-Arg-MCA, Z-Arg-Arg-MCA, and Arg-MCA. These results suggest that the tryptic protease in Xenopus sperm is involved in fertilization, most likely by participating in egg activation.  (+info)

Allosteric modulation of BPTI interaction with human alpha- and zeta-thrombin. (3/706)

In this study, thrombin interaction with the basic pancreatic trypsin inhibitor (BPTI) was investigated in the presence of different allosteric modulators of thrombin, that is the C-terminal hirudin peptide 54-65 (Hir54-65), a recombinant thrombomodulin form (TMEGF4-6) and Na+. BPTI binding to alpha-thrombin is positively linked to Na+. Under low sodium concentration (5 mM Na+) the BPTI affinity for alpha-thrombin was roughly threefold lower than in the presence of 150 mM sodium (Ki = 320 microM vs. 100 microM). The hirudin fragment, which binds to the fibrinogen recognition site (FRS) of thrombin, induced a progressive and saturable decrease (3.6-fold) of alpha-thrombin affinity for BPTI, whereas the thrombomodulin peptide, which binds to a more extended region of FRS, caused a 5.5-fold increase of the enzyme affinity for the inhibitor. The opposite effect exerted by Hir54-65 and TMEGF4-6 was also observed for BPTI interaction with zeta-thrombin, in which the amidic bond between W148 and T149 is cleaved. However, in this case the effect by Hir54-65 and TMEGF4-6, although qualitatively similar to that observed with alpha-thrombin, had a smaller magnitude. Thrombin hydrolysis of Protein C was also differently affected by Hir54-65 and TMEGF4-6 peptides. While the latter enhanced the Protein C activation, the former caused a reduction of both alpha- and zeta-thrombin kcat/K(m)' for Protein C cleavage. These results showed that (a) Na+ facilitates BPTI interaction with thrombin; (b) Hir54-65 and TMEGF4-6, though sharing in part the same binding site at the thrombin FRS, can affect in opposite way thrombin's interaction with BPTI and Protein C; (c) such findings along with the results obtained with zeta-thrombin might be explained by admitting that the thermodynamic linkage between FRS and the critical W60-loop is also controlled by ligation and/or conformational state of the W148 insertion loop.  (+info)

Strategy for balancing anticoagulation and hemostasis in aortocoronary bypass surgery: blood conservation and graft patency. (4/706)

The minimal effective dose of aprotinin on hemostasis under normothermic perfusion, the influence of anticoagulant therapy on graft patency, and the thromboembolic and hemorrhagic events were investigated after aortocoronary bypass graft operation (CABG). One hundred CABG patients under normothermic perfusion were randomly divided into the following groups: (1) coumadin plus acetylsalicylic acid (ASA) (n=32); no aprotinin used during cardiopulmonary bypass (CPB); (2) minimal-dose, 10(6) KIU during CPB, aprotinin used, followed by ASA and coumadin (n=36); and (3) very low-dose, total of 2x10(6) KIU before CPB and during CPB; aprotinin used; anticoagulation therapy with heparin early after surgery and followed by replacement with ASA and coumadin (n=32). The patency of arterial grafts was 100% in all groups. The patency of vein grafts was 95-98% and there was no difference among the groups. The blood loss was significantly reduced in both aprotinin groups (groups 2 and 3) compared to the coumadin plus ASA group, although no difference existed between the 2 aprotinin groups. Postoperative thrombotic and hemorrhagic events were not observed in any group. From this study, it was concluded that 10(6) KIU aprotinin in pump-prime-only followed by oral ASA and coumadin was the recommendation from the benefit/cost consideration.  (+info)

Comparison of anionic and cationic trypsinogens: the anionic activation domain is more flexible in solution and differs in its mode of BPTI binding in the crystal structure. (5/706)

Unlike bovine cationic trypsin, rat anionic trypsin retains activity at high pH. This alkaline stability has been attributed to stabilization of the salt bridge between the N-terminal Ile16 and Asp194 by the surface negative charge (Soman K, Yang A-S, Honig B, Fletterick R., 1989, Biochemistry 28:9918-9926). The formation of this salt bridge controls the conformation of the activation domain in trypsin. In this work we probe the structure of rat trypsinogen to determine the effects of the surface negative charge on the activation domain in the absence of the Ile16-Asp194 salt bridge. We determined the crystal structures of the rat trypsin-BPTI complex and the rat trypsinogen-BPTI complex at 1.8 and 2.2 A, respectively. The BPTI complex of rat trypsinogen resembles that of rat trypsin. Surprisingly, the side chain of Ile16 is found in a similar position in both the rat trypsin and trypsinogen complexes, although it is not the N-terminal residue and cannot form the salt bridge in trypsinogen. The resulting position of the activation peptide alters the conformation of the adjacent autolysis loop (residues 142-153). While bovine trypsinogen and trypsin have similar CD spectra, the CD spectrum of rat trypsinogen has only 60% of the intensity of rat trypsin. This lower intensity most likely results from increased flexibility around two conserved tryptophans, which are adjacent to the activation domain. The NMR spectrum of rat trypsinogen contains high field methyl signals as observed in bovine trypsinogen. It is concluded that the activation domain of rat trypsinogen is more flexible than that of bovine trypsinogen, but does not extend further into the protein core.  (+info)

Effect of glycerol on the interactions and solubility of bovine pancreatic trypsin inhibitor. (6/706)

The effects of additives used to stabilize protein structure during crystallization on protein solution phase behavior are poorly understood. Here we investigate the effect of glycerol and ionic strength on the solubility and strength of interactions of the bovine pancreatic trypsin inhibitor. These two variables are found to have opposite effects on the intermolecular forces; attractions increase with [NaCl], whereas repulsions increase with glycerol concentration. These changes are mirrored in bovine pancreatic trypsin inhibitor solubility where the typical salting out behavior for NaCl is observed with higher solubility found in buffers containing glycerol. The increased repulsions induced by glycerol can be explained by a number of possible mechanisms, all of which require small changes in the protein or the solvent in its immediate vicinity. Bovine pancreatic trypsin inhibitor follows the same general phase behavior as other globular macromolecules where a robust correlation between protein solution second virial coefficient and solubility has been developed. This study extends previous reports of this correlation to solution conditions involving nonelectrolyte additives.  (+info)

Hydroiodic acid attachment kinetics as a chemical probe of gaseous protein ion structure: bovine pancreatic trypsin inhibitor. (7/706)

The kinetics of attachment of hydroiodic acid (HI) to the (M + 6H)6+ ions of native and reduced forms of bovine pancreatic trypsin inhibitor (BPTI) in the quadrupole ion trap environment are reported. Distinctly nonlinear (pseudo first-order) reaction kinetics are observed for reaction of the native ions, indicating two or more noninterconverting structures in the parent ion population. The reduced form, on the other hand, shows very nearly linear reaction kinetics. Both forms of the parent ion attach a maximum of five molecules of hydroiodic acid. This number is expected based on the amino acid composition of the protein. There is a total of 11 strongly basic sites in the protein (i.e., six arginines, four lysines, and one N-terminus). An ion with protons occupying six of the basic sites has five available for hydroiodic acid attachment. The kinetics of successive attachment of HI to the native and reduced forms of BPTI also differ, particularly for the addition of the fourth and fifth HI molecules. A very simple kinetic model describes the behavior of the reduced form reasonably well, suggesting that all of the neutral basic sites in the reduced BPTI ions have roughly equal reactivity. However, the behavior of the native ion is not well-described by this simple model. The results are discussed within the context of differences in the three-dimensional structures of the ions that result from the presence or absence of the three disulfide linkages found in native BPTI. The HI reaction kinetics appears to have potential as a chemical probe of protein ion three-dimensional structure in the gas phase. Hydroiodic acid attachment chemistry is significantly different from other chemistries used to probe three-dimensional structure and hence, promises to yield complementary information.  (+info)

Urokinase receptor (uPAR, CD87) is a platelet receptor important for kinetics and TNF-induced endothelial adhesion in mice. (8/706)

BACKGROUND: Urokinase plasminogen activator receptor (uPAR, CD87) is a widely distributed 55-kD, glycoprotein I-anchored surface receptor. On binding of its ligand uPA, it is known to increase leukocyte adhesion and traffic. Using genetically deficient mice, we explored the role of uPAR in platelet kinetics and TNF-induced platelet consumption. METHODS AND RESULTS: Anti-uPAR antibody stained platelets from normal (+/+) but not from uPAR-/- mice, as seen by fluorescence-activated cell sorter analysis. 51Cr-labeled platelets from uPAR-/- donors survived longer than those from +/+ donors when injected into a +/+ recipient. Intratracheal TNF injection induced thrombocytopenia and a platelet pulmonary localization, pronounced in +/+ but absent in uPAR-/- mice. Aprotinin, a plasmin inhibitor, decreased TNF-induced thrombocytopenia. TNF injection markedly reduced the survival and increased the pulmonary localization of 51Cr-labeled platelets from +/+ but not from uPAR-/- donors, indicating that it is the platelet uPAR that is critical for their response to TNF. As seen by electron microscopy, TNF injection increased the number of platelets and polymorphonuclear neutrophils (PMNs) in the alveolar capillaries of +/+ mice, whereas in uPAR-/- mice, platelet trapping was insignificant and PMN trapping was slightly reduced. Platelets within alveolar capillaries of TNF-injected mice were activated, as judged from their shape, and this was evident in +/+ but not in uPAR-/- mice. CONCLUSIONS: These results demonstrate for the first time the critical role of platelet uPAR for kinetics as well as for activation and endothelium adhesion associated with inflammation.  (+info)

UPDATE 5/14/2008]: Following publication of the Blood conservation using antifibrinolytics: A randomized trial in a cardiac surgery population (BART) study in the May 14, 2008 online issue of The New England Journal of Medicine, Bayer Pharmaceuticals, the manufacturer of Trasylol (aprotinin), notified the FDA of their intent to remove all remaining supplies of Trasylol from hospital pharmacies and warehouses. [See FDA Statement]. Because Trasylol has been shown to decrease the need for red blood cell transfusions in patients undergoing coronary artery bypass surgery, future supplies of Trasylol will continue to be available through the company as an investigational drug under a special treatment protocol. In November 2007, Bayer suspended the marketing of this drug until final results of the BART study became available. The BART study showed an increase in the risk of death with Trasylol compared with aminocaproic acid and tranexamic acid, consistent with findings from other recent studies. FDA ...
en] BACKGROUND: Cardiopulmonary bypass (CPB) initiates a whole-body inflammatory response where complement and neutrophil activation and cytokine release play an important role. This prospective trial examined the effects of both heparin-coated circuits and aprotinin on the inflammatory processes during CPB, with respect to cytokine release and neutrophil activation. METHODS: Two hundred patients undergoing cardiac surgery were randomized in four groups of 50 patients each: heparin-coated circuit with aprotinin (HCO-A) or without aprotinin (HCO) administration, and uncoated circuit with aprotinin (C-A) or without aprotinin administration (C). In groups receiving aprotinin, a high-dose regimen was given. In all groups, high initial doses of heparin were used (3 mg/kg intravenously). Tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and IL-8, and myeloperoxidase and elastase levels were measured in plasma samples taken before, during, and after CPB. RESULTS: In all groups, the ...
Trasylol is a clotting drug usually given to patients after cardiac surgery. Two studies published in the New England Journal of Medicine strongly suggest that Trasylol is dangerous. The first study looked at 10,000 patients who underwent bypasses at Duke University Medical Center from 1996 through 2005. It found that 6.4 percent of patients who were given Trasylol died within 30 days of the surgery, a rate nearly 2.5 times higher than patients who received a different drug, or who received no treatment for bleeding. The second study, financed by Bayer, looked at about 78,000 patients nationwide from 2003 to 2006. Researchers found that the risk of death was 64 percent higher in the Trasylol group than in those taking another medication. If you were given Trasylol during or after surgery and suffered kidney failure, or a family member was given Trasylol after surgery and then passed away unexpectedly, please contact us.. ...
Bovine pancreatic trypsin inhibitor (BPTI) is a 58-residue basic peptide that is a representative member of a widely distributed class of serine protease inhibitors known as Kunitz inhibitors. BPTI is also homologous to dendrotoxin peptides from mamba snake venom that have been characterized as inhibitors of various types of voltage-dependent K+ channels. In this study we compared the effect of DTX-I, a dendrotoxin peptide, and BPTI on large conductance Ca(2+)-activated K+ channels from rat skeletal muscle using planar bilayer methodology. As previously found for DTX-I (1990. Neuron. 2:141-148), BPTI induces the appearance of distinct subconductance events when present on the internal side of maxi K(Ca) channels. The single channel kinetics of substate formation follow the predictions of reversible binding of the peptide to a single site or class of sites with a Kd of 4.6 microM at 0 mV and 50 mM symmetrical KCl. The apparent association rate of BPTI binding decreases approximately 1,000-fold ...
The drug aprotinin (Trasylol, previously Bayer and now Nordic Group pharmaceuticals), is a small protein bovine pancreatic trypsin inhibitor (BPTI), or basic trypsin inhibitor of bovine pancreas, which is an antifibrinolytic molecule that inhibits trypsin and related proteolytic enzymes. Under the trade name Trasylol, aprotinin was used as a medication administered by injection to reduce bleeding during complex surgery, such as heart and liver surgery. Its main effect is the slowing down of fibrinolysis, the process that leads to the breakdown of blood clots. The aim in its use was to decrease the need for blood transfusions during surgery, as well as end-organ damage due to hypotension (low blood pressure) as a result of marked blood loss. The drug was temporarily withdrawn worldwide in 2007 after studies suggested that its use increased the risk of complications or death; this was confirmed by follow-up studies. Trasylol sales were suspended in May 2008, except for very restricted research ...
The present study demonstrates the cardioprotective qualities of aprotinin. The mechanisms of these effects are likely to include reduced protease induced expression of stored proteins such as P-selectin. In addition, this study provides novel evidence that aprotinin reduces inflammatory gene expression and hence de novo inflammatory protein synthesis. These effects of aprotinin on myocardial protein expression are also associated with a profound reduction of leukocyte accumulation, myocardial necrosis and myocardial apoptosis.. The timing of aprotinin administration is important because myocardial injury and leukocyte accumulation were substantially greater when administration was delayed until after reperfusion. This finding lends weight to the notion that the earliest stages of tissue injury involve the expression of proimflammatory mediators whose release is activated by the action of triggering proteases17 such as complement, coagulation factors (eg, thrombin and plasmin) and kinins. The ...
Trasylol injection/infusion contains the active ingredient aprotinin. (NB. Aprotinin is also available without a brand name, ie as the generic medicine.)

... , or an aprotinin injection, is used to minimize blood loss during heart surgery. It is a protein that, when injected into the patient, slows down blood clotting processes, reducing the need for blood transfusions during complicated heart and liver surgeries. When used properly, it can decrease the chances of organ damage likely to result from low blood pressure. The uses of Trasylol, however, far surpass surgical purposes. It is also used in blood transfusions for patients who are undergoing cardiopulmonary bypass, slows down multiple intermediaries of inflammation, holds back proinflammatory cytokine release, which reduces complement activation, defective thrombin and plasmin-induced platelets. The stabilization of the platelet membranes and preservation of their functions rounds out the uses of this drug. Bayer Pharmaceuticals manufactured the product for those patients who undergo coronary artery bypass grafting to block the enzymes that dissolve blood clots.. In January of 2006, a ...

The serine esterase TL2 from human T4(+) lymphocytes is a binding component to HIV-1 glycoprotein gp120 and seems to play a role in the HIV-1 infection mechanism. Recombinant variants of the Kunitz-type serine proteinase inhibitor aprotinin were investigated for their ability to inhibit tryptase TL2 and the binding of gp120 to this enzyme, Furthermore, the viral replication of HIV-1 was investigated in H9 cell cultures under the influence of recombinant aprotinin and bikunin variants. In contrast to native aprotinin, the recombinant variant [Arg(15), Phe(17), Glu(52)]aprotinin with a reactive-site sequence homologous to the V3 loop of HIV-1 gp120 showed a specific inhibition of tryptase TL2 (>80%). However, the [Leu(15), Phe(17), Glu(52)]aprotinin variant with hydrophobic subsites was the most potent inhibitor of the binding of gp120 to tryptase TL2 (68%). Our results show that the enzyme activity of purified tryptase TL2 is inhibited not only by variants with basic amino acids, but also those ...

To the Editor:. I read with great interest the excellent article by Furnary and colleagues1 detailing an analysis of aprotinin and acute dialysis-dependent renal failure in cardiac surgery patients. Their multivariate analysis has demonstrated that increasing perioperative red blood cell transfusion, rather than aprotinin, is an independent risk factor for acute renal failure after cardiac surgery.. The data analysis as presented, however, does not account for angiotensin blockade in the presence of aprotinin, a described significant risk factor for perioperative renal injury.2 Consequently, if a significant percentage of the aprotinin cohort were exposed to angiotensin-converting enzyme inhibition, it might confound the results of the multivariate analysis. If the data for this variable are readily available, it would be interesting see if this potential confounder could have had any significant statistical effect.. Furthermore, the authors state in their discussion that meta-analysis of ...

Significance:. Complex surgery of the ascending thoracic aorta and the aortic arch requires use of cardiopulmonary bypass (CPB) with moderate or profound total body hypothermia and circulatory arrest. As expected, coagulation disorder can be common and severe requiring multiple transfusions of blood product, which, in turn, is associated with increased risk of morbidity and mortality. Over the years, many techniques have been employed to ameliorate CPB- related bleeding with some agents such as aprotinin proving to be efficacious but centered in controversy either because of high cost or due to safety concerns.. Aprotinin is a serine protease inhibitor, intended to limit blood loss in patients undergoing surgery, was approved for use 13 years ago, and now administered in more than 250,000 surgery patients per year. Although its mechanism of action is not entirely known, it is shown to interfere with contact activation, preserve platelet function, inhibit fibrinolysis, and having some ...
1BTI: Crevice-forming mutants in the rigid core of bovine pancreatic trypsin inhibitor: crystal structures of F22A, Y23A, N43G, and F45A.
In contrast to molecular chaperones that couple protein folding to ATP hydrolysis, protein disulfide-isomerase (PDI) catalyzes protein folding coupled to formation of disulfide bonds (oxidative folding). However, we do not know how PDI distinguishes folded, partly-folded and unfolded protein substrates. As a model intermediate in an oxidative folding pathway, we prepared a two-disulfide mutant of basic pancreatic trypsin inhibitor (BPTI) and showed by NMR that it is partly-folded and highly dynamic. NMR studies show that it binds to PDI at the same site that binds peptide ligands, with rapid binding and dissociation kinetics; surface plasmon resonance shows its interaction with PDI has a Kd of ca. 10−5 M. For comparison, we characterized the interactions of PDI with native BPTI and fully-unfolded BPTI. Interestingly, PDI does bind native BPTI, but binding is quantitatively weaker than with partly-folded and unfolded BPTI. Hence PDI recognizes and binds substrates via permanently or transiently
A new <"http://www.yourlawyer.com/topics/overview/trasylol">Trasylol study is shedding more light on possible reasons behind the drug’s higher-than normal death rate. According to British researchers, while use of the clotting drug aprotininâ€"known as Trasylolâ€"appears safe during on-pump cardiac surgeries, it appears that combining it with angiotensin-converting enzyme inhibitorsâ€"or ACE inhibitorsâ€"during off-pump cardiac surgeries shows a significant risk of post-operative kidney dysfunction. Researchers analyzed 9,875 cardiac surgery patients, most of who (5,434) had on-pump cardiac surgery, meaning their hearts were stopped and they were hooked up to a heart-bypass machine during surgery. The other patients had off-pump cardiac surgery, in which surgeons operated on their beating hearts.. Trasylol is used to reduce perioperative blood loss and the need for blood transfusion in those patients undergoing cardiopulmonary bypass during coronary artery bypass graft ...

ISSN 0102-7638. http://dx.doi.org/10.1590/S0102-76382002000100008.. BACKGROUND: The use of aprotinin, a antifibrinolytic agent, has been shown to decrease damaging effects on cardiopulmonary bypass in fibrinolytic system, which may improve hemostasis. OBJECTIVE: To study the effect of low dose aprotinin in patients undergoing extracorporeal circulation. METHOD: Seventeen patients, underwent cardiopulmonary bypass to mitral valve replacement, was ramdomized in two groups: I (control) ¾ 9 patients received placebo after anesthesia induction and each hour in the priming; II (aprotinin) ¾ 8 patients received after anesthesia induction 30,000 KIU/kg and 7.500 KIU/kg each hour in the priming during the perfusion. The blood loss was observed through the first 24 hours postoperatively. Arterial blood samples were taken after ...

Aprotinin (Trasylol) caused twice as many deaths as two otherantifibrinolytics, despite a modest reduction in the risk of bleeding,according to a study published today in the New England Journal of Medicine. A co-author of the study told Cardiovascular Business News that the risks of the drug could have been known a decade ago.
Furthermore, "The researchers also found that cheaper alternatives ("$10 to $50" per patient) to Trasylol ($1000 per patient) were just as effective in limiting blood loss." The New York Times wrote, "The [New England Journal of Medicine] article said that halting aprotinin use globally would prevent 10,000 to 11,000 cases of kidney failure a year and save more than $1 billion a year in dialysis costs as well as nearly $250 million spent on the drug itself." In addition, "The study is significant because it was conducted without drug-industry funding at 69 medical centers, including many of the top U.S. hospitals." Naturally, Bayer, the manufacturer of Trasylol, a drug which "in the first nine months [of 2005]" had a "world-wide sales of just less than $200 million" and is used in 150,000 patients in the U.S., "believes that Trasylol is a safe and effective treatment." Though the study was large, Bayer points out that it was observational and not a randomized trial. According to the New York ...
Research being published in the New England Journal of Medicine today concluded that use of Bayers Trasylol (aprontin), a standard treatment to limit blood loss during heart surgeries, were at an increased risk of kidney failure, heart attacks and strokes, compared with patients taking alternative drugs, aminocaproic acid and tranexamic acid, or no drugs at all.

PY - 2004/5/24. Y1 - 2004/5/24. N2 - Cardiopulmonary bypass activates an array of cellular and humoral inflammatory mechanisms that culminate in diverse or organ-specific injury. A manifestation of inflammatory injury to the heart, atrial fibrillation ranks among the most frequent and potentially life-threatening postsurgical complications. Pulmonary manifestations of the inflammatory response are also of major concern. Neutrophils activated by passage through the extracorporeal circuit inflict local injury and provoke the inflammatory cascade by producing oxyradicals and proinflammatory factors. This study tested if a combination of leukocyte depletion and aprotinin suppression of neutrophils could minimize postbypass atrial fibrillation and pulmonary dysfunction. In part one, two randomized groups of ...
The new observational study of 3876 patients from 62 medical centers was conducted between November 11, 1996, and December 7, 2006. Survival rates were assessed at 6 weeks, 6 months, and annually for 5 years after CABG surgery. The results were rather alarming: During the five-year examination period, 223 deaths occurred among 1072 aprotinin-treated patients, equal to 20.8 percent of the group. That death rate was nearly two-thirds greater than that of control patients (12.7 percent). After controlling for various patient factors, the results showed that Trasylol patients faced a 48 percent greater risk of death within a five-year period than those not using any medication.. Patients treated with aminocaproic acid had a death rate of 15.8 percent and those treated with tranexamic acid patients had a death rate of 14.7 percent, meaning either of these two alternative therapies carries with it a significantly lower mortality risk than aprotinin. Significantly, the authors noted that ...

TAP is a reversible, slow, tight-binding inhibitor of solution-phase Xa with a Ki of 0.18 nM.34 Assembly of Xa into the prothrombinase (Va/Xa) complex on an anionic membrane surface results in a 30-fold enhanced binding of TAP (Ki = 5.3 pM) and a modest 3-fold increase in the rate of inhibition.50 Despite an extremely high affinity for prothrombinase, TAP possesses only moderate anticoagulant activities in both TF-initiated coagulation and aPTT assays (Table 2 and Figure 4). The modest anticoagulant activity of TAP was thought to be due to its relatively slow rate of prothrombinase inhibition.51 The aprotinin mutant 6L15 binds membrane-associated TF/VIIa with very high affinity (Ki = 0.2 nM),27 yet, consistent with a previous report,52 it is a very poor inhibitor of TF-initiated coagulation (Table 2). In comparison, TAP-ANV and ANV-6L15 are close to 2 and 3 orders of magnitude, respectively, more potent than their Kunitz domains alone in TF-initiated plasma clotting. The greatly enhanced ...

Fiber optic Raman spectroscopy is used for in situ monitoring of supersaturation during the hanging-drop crystallization of aprotinin. Schwartz and Berglund (1999) previously demonstrated this technique for lysozyme crystallization and showed it combines two critical elements for protein crystallization studies: real-time monitoring/ control of supersaturation and small amounts of sample. Experiments were carried out using 10 muL of protein solution. A partial-least-squares (PLS) calibration based on Raman spectra of standard solutions allowed an accurate measurement of aprotinin in a range of 2-100 mg/mL with a standard error of 0.54 mg/mL determined by a leave-one-out cross validation. A 10x microscope attached to a Raman fiber optic probe allowed the monitoring of the hanging-drop liquid phase in a noninvasive and real-time mode. Aprotinin solubility determined by measuring the protein concentration of drop solution at equilibrium decreased with increase in NaCl concentration. By continuously ...

The single-parameter Gamma matrix of force constants proposed by the Gaussian Network Model (GNM) is iteratively modified to yield native state fluctuations that agree exactly with experimentally observed values. The resulting optimized Gamma matrix contains residue-specific force constants that may be used for an accurate analysis of ligand binding to single or multiple sites on proteins. Bovine Pancreatic Trypsin Inhibitor (BPTI) is used as an example. The calculated off-diagonal elements of the Gamma matrix, i.e., the optimized spring constants, obey a Lorentzian distribution. The mean value of the spring constants is approximately -0.1, a value much weaker than -1 of the GNM. Few of the spring constants are positive, indicating repulsion between residues. Residue pairs with large number of neighbors have spring constants around the mean, -0.1. Large negative spring constants are between highly correlated pairs of residues. The fluctuations of the distance between anticorrelated pairs of residues are
A radiolabeled human neutrophil elastase inhibitor (EPI-HNE-2) may represent an improved nuclear medicine imaging agent for inflammation and infection. This peptide displays rapid pharmacokinetics due to its low molecular weight and localizes specifically on neutrophil elastase released in inflammatory sites by activated neutrophils. METHODS: In this investigation, the peptide was radiolabeled with 99mTc using N-hydroxysuccinimidyl S-acetylmercaptoacetyltriglycline (NHS-MAG3) as a bifunctional chelator and was administered on 18 occasions to 5 rhesus monkeys with inflammation/infection. RESULTS: Plasma clearance was rapid, with liver and kidneys representing the major organs of accumulation. No evidence of toxicity, dosage effects, or circulating antiMAG3-EPI-HNE-2 antibodies was observed. Specificity of localization was established using radiolabeled bovine pancreatic trypsin inhibitor (a non-hNE-binding peptide of similar size) as a nonspecific negative control peptide and by predosing with unlabeled

Background: PYY is a gut hormone that physiologically inhibits appetite. Currently only radioimmunoassay (RIA) techniques are available for its estimation. The aim of the study was to evaluate our in-house assay for precision, detection limit, interference of haemolysis, suitability of serum versus plasma and biological variation within one subject.. Method: All samples were obtained from one subject on two occasions following an over night fast and the consumption of 1000 and 3000 kcal meals on the respective days. Plasma was aliquoted in multiple samples. Coefficient of variation (CV) was measured at three concentrations (13.4, 16.4, 31.7pmol/L). The influence of haemolysis was evaluated by diluting severely haemolysed blood with non haemolysed blood obtained at the same venepuncture. All plasma samples were obtained in lithium heparin and trasylol tubes. Serum samples were obtained in a tube with trasylol and a clot activator. Carry over and the detection limit of the assay were also ...

Although it was long suspected that VHS is an RNase (11, 12, 22, 32, 52), unambiguous evidence that VHS is an endoribonuclease with a substrate specificity of RNase A emerged from studies of a protein purified to homogeneity (46, 47).

Vesicle Transport Studies. Membrane vesicles were prepared from HEK293 cells, which were infected with human BCRP-, MRP2-, and MRP4-recombinant adenoviruses, as described previously (Hasegawa et al., 2007; Imaoka et al., 2007). In brief, HEK293 cells were infected with recombinant adenovirus containing human MRP4 [10 multiplicity of infection (MOI)] and BCRP (2 MOI). As negative controls, cells were infected with a virus containing green fluorescence protein cDNA (10 MOI). Cells were harvested 48 h after infection, and membrane vesicles were isolated by the hypotonic method (Hasegawa et al., 2007; Imaoka et al., 2007). Cells were diluted 40-fold with hypotonic buffer (1 mM Tris-HCl, 0.1 mM EDTA, pH 7.4, at 4°C) and stirred gently for 1 h on ice in the presence of 2 mM phenylmethylsulfonyl fluoride, 5 μg/ml leupeptin, 1 μg/ml pepstatin, and 5 μg/ml aprotinin.

The purpose of this study was to develop a fibrin gel system capable of serving as a three dimensional scaffold for the chondrogenesis of rabbit bone marrow mesenchymal stem cells (BM-MSCs) and to examine the effect of two fibrinolytic inhibitors, aprotinin and aminohexanoic acid, on this system. Rabbit BM-MSCs were obtained from the tibias and femurs of New Zealand white rabbits. After chondrogenic potential of BM-MSCs was verified by pellet culture, 2 x 106 cells were pelleted and suspended in fibrinogen (80mg/ml) and then mixed with equal parts of thrombin (5 IU/ml). The specimen were then divided into four groups: aprotinin control (with aprotinin); aprotinin + transforming growth factor (TGF-beta) (with aprotinin and TGF-beta 1); amino control (with aminohexanoic acid); and amino+TGF-beta (with aminohexanoic acid and TGF- beta1). Each of these groups was further divided into three groups depending on the concentration of the inhibitor. Both of the aprotinin groups received 0.0875, 0.175, or 0.35
Lung tissue was also harvested for MPO measurements. Systemic leucocyte counts Tail vein blood was mixed no with Turks solution (0.2 mg gentian violet in 1 mL glacial acetic acid, 6.25% v/v) in a 1:20 dilution. Leucocytes were identified as monomorphonuclear and polymorphonuclear cells in a Burker chamber. Serum amylase Amylase was quantified in serum with a commercially available assay (Reflotron?, Roche Diagnostics GmbH, Mannheim, Germany). MPO assay Frozen pancreatic and lung tissue were pre-weighed and homogenized in 1-mL mixture (4:1) of PBS and aprotinin 10 000 KIE?mL?1 (Trasylol?, Bayer HealthCare AG, Leverkusen, Germany) for 1 min. The homogenate was centrifuged (153 39��g, 10 min) and the supernatant was stored at ?20��C and the pellet was used for MPO assay as previously described (Laschke et al.. , 2007). In brief, the pellet was mixed with 1 mL of 0.5% hexadecyltrimethylammonium bromide. Next, the sample was frozen for 24 h and then thawed, sonicated for 90 s, put in a water ...

By Byron J. Richards, CCN. February 9, 2007. NewsWithViews.com. The FDA is steamrolling its way to a grand vision of repressive health care based on profits for Big Pharma and new biotech companies at the expense of human health. Human death means little to the FDA, permitting mass killings of Americans while protecting Big Pharma profits. This year the FDA is being given more money (federal funding up 5% to 1.5 billion) without any accountability or effective Congressional oversight. This means that instead of using the money to meaningfully improve drug safety, the FDA will carry on its pet projects that include forwarding the health component of the Bush administration�s North American Union, limiting health freedom by harassing dietary supplement companies so as to reduce access to safe and effective drug competition, and actively turning the FDA into a drug company. A current case in point is the heart bypass drug, Trasylol, a medication often given so patients don�t bleed too much ...
Blood must be collected into iced glass tubes containing EDTA as an anticoagulant. The tubes must be immersed in an ice-bath at 2 - 8°C throughout the entire collection and handling procedure.. Immediately following collection add 5000 Kallikrein Inactivating Units (KIU) per 10mL of whole blood in the form of Trayslol (500uL) or Aprotinin (1mg). Mix gently but thoroughly and keep chilled (on ice) until separation.. Centrifuge the samples in a refrigerated centrifuge at 2000g to separate the plasma. Separate the plasma using a glass pasteur pipette and transfer the plasma into glass tubes (aliquots of 0.6mL required) and freeze immediately. Store the plasma frozen at less than -10°C until assayed.. Samples must be transported to the laboratory frozen and remain frozen until assayed. Dry ice is recommended. Lipaemic and haemolysed samples may affect the assay so great care is needed when blood sampling to ensure samples do not become haemolysed. Courier transport is essential.. At least 1mL of ...
Results. Western blot analysis of PKCα and PKCγ translocation. N/N 1003A cells were treated with 200 nM TPA (a conventional PKC activator) for 60 min, 10 ng/ml EGF, or 15 ng/ml bFGF. Confluent cells were taken up in ice cold 50 mM Tris, 20 mM MgCl2, 25 μg/ml aprotinin, and 25 μg/ml leupeptin, pH 7.5 and sonicated. The lysate was spun down for 60 min at 35,000 rpm (100,000x g). Western blot analysis was performed on the pellet that contained plasma membrane and the supernatant that contained cytosolic components.. Upon activation by TPA, PKCα and PKCγ should translocate from the cytosol to the plasma membrane [25]. In order to determine if PKCα and PKCγ translocate to the plasma membrane in N/N 1003A cells upon activation, TPA was added to the cell culture media for 60 min. PKCα did translocate to the membrane (pellet fraction) upon activation of the enzyme by TPA (Figure 1A, lane 2 versus lane 4). PKCγ also translocated to the membrane (pellet fraction, Figure 1B, lane 2 versus lane ...

TY - JOUR. T1 - Method of determining protein conformations by the two-dimensional nuclear overhauser enhancement spectroscopy data. AU - Sherman, S. A.. AU - Andrianov, A. M.. AU - Akhrem, A. A.. PY - 1987/4. Y1 - 1987/4. N2 - A method is suggested to determine the most probable values of the angles, y of the protein backbone by the data on the availability and absence of d connectivities in the two-dimensional nuclear Overhauser enhancement spectra. In view of this, the dependences of the protonproton distances in dipeptide units of L-amino acid residues on the dihedral angles tp, y, x, are considered and the conformational states of amino acid residues of the proteins with the known spatial structure are analysed statistically. The potentialities of the method are assessed with the aid of model spectral nuclear magnetic resonance (NMR) parameters obtained from the X-ray data for the bovine pancreatic trypsin inhibitor and avian pancreatic polypeptide. It is shown that the developed procedure ...
Inclusion Criteria:. All trauma patients with ongoing significant haemorrhage (systolic blood pressure less than 90 mmHg and/or heart rate more than 110 beats per minute), or who are considered to be at risk of significant haemorrhage, and are within 8 hours of the injury, are eligible for trial entry if they appear to be at least 16 years old. Although entry is allowed up to 8 hours from injury, the earlier that patients can be treated the better.. Exclusion Criteria:. The fundamental eligibility criterion is the responsible doctors uncertainty as to whether or not to use an antifibrinolytic agent in a particular adult with traumatic haemorrhage. Patients for whom the responsible doctor considers there is a clear indication for antifibrinolytic therapy should not be randomised. Likewise, patients for whom there is considered to be a clear contraindication to antifibrinolytic therapy (such as, perhaps, those who have clinical evidence of a thrombotic disseminated intravascular coagulation) ...
Fibrinolysis is a process that prevents blood clots from growing and becoming problematic. This process has two types: primary fibrinolysis and secondary fibrinolysis. The primary type is a normal body process, whereas secondary fibrinolysis is the breakdown of clots due to a medicine, a medical disorder, or some other cause. In fibrinolysis, a fibrin clot, the product of coagulation, is broken down. Its main enzyme plasmin cuts the fibrin mesh at various places, leading to the production of circulating fragments that are cleared by other proteases or by the kidney and liver. Plasmin is produced in an inactive form, plasminogen, in the liver. Although plasminogen cannot cleave fibrin, it still has an affinity for it, and is incorporated into the clot when it is formed. Tissue plasminogen activator (t-PA) and urokinase are the agents that convert plasminogen to the active plasmin, thus allowing fibrinolysis to occur. t-PA is released into the blood very slowly by the damaged endothelium of the ...
Kallikreins (tissue and plasma kallikreins) are serine proteases that liberate kinins (bradykinin and kallidin) from the kininogens, which are plasma proteins that are converted into vasoactive peptides. The Kallikrein Inhibitor Peptide corresponds to aa386-391 of bovine kininogen-1 that encompasses the aa388-389 kallikrein proteolytic site. The synthetic kallikrein inhibitor can attenuate breast cancer cell invasion, therefore it is investigated for its role in invasion and metastasis of cancer cells.. ...

[more ▼]. 5 micrograms of human beta-endorphin were labelled with 2 mCi 125I by the chloramine T technique. After two gel filtrations on Sephadex G-15 and on Sephadex G-50 in phosphate buffer with EDTA, Trasylol and mercapto-ethanol, a pure tracer was obtained with a specific activity about 150 microCi/ug. Kept at + 4 degrees C, the tracer remained utilizable for 30 days without loss of immunoreactivity. The labelling with lactoperoxydase and the use of another gel filtration method (filtration on Aca 202) gave a 125I beta-END tracer with the same immunoreactivity. The binding of this tracer to the antibody of an anti-beta-END antiserum diluted at 1/8000 was 32% with a non specific binding ...
