Abstract
MOTIVATION Native top-down proteomics (nTDP) integrates native mass spectrometry (nMS) with top-down proteomics (TDP) to provide comprehensive analysis of protein complexes together with proteoform identification and characterization. Despite significant advances in nMS and TDP software developments, a unified and user-friendly software package for analysis of nTDP data remains lacking. RESULTS We have developed MASH Native to provide a unified solution for nTDP to process complex datasets with database searching capabilities in a user-friendly interface. MASH Native supports various data formats and incorporates multiple options for deconvolution, database searching, and spectral summing to provide a "one-stop shop" for characterizing both native protein complexes and proteoforms. AVAILABILITY AND IMPLEMENTATION The MASH Native app, video tutorials, written tutorials, and additional documentation are freely available for download at https://labs.wisc.edu/gelab/MASH_Explorer/MASHSoftware.php.

Abstract
MolProbity is a powerful software program for validating structures of proteins and nucleic acids. Although MolProbity includes scripts for batch analysis of structures, because these scripts analyze structures one at a time, they are not well suited for the validation of a large dataset of structures. We have created a version of MolProbity (MolProbity-HTC) that circumvents these limitations and takes advantage of a high-throughput computing cluster by using the HTCondor software. MolProbity-HTC enables the longitudinal analysis of large sets of structures, such as those deposited in the PDB or generated through theoretical computation-tasks that would have been extremely time-consuming using previous versions of MolProbity. We have used MolProbity-HTC to validate the entire PDB, and have developed a new visual chart for the BioMagResBank website that enables users to easily ascertain the quality of each model in an NMR ensemble and to compare the quality of those models to the rest of the PDB.

Abstract
The BioMagResBank (BMRB: www.bmrb.wisc.edu) is a repository for experimental and derived data gathered from nuclear magnetic resonance (NMR) spectroscopic studies of biological molecules. BMRB is a partner in the Worldwide Protein Data Bank (wwPDB). The BMRB archive consists of four main data depositories: (i) quantitative NMR spectral parameters for proteins, peptides, nucleic acids, carbohydrates and ligands or cofactors (assigned chemical shifts, coupling constants and peak lists) and derived data (relaxation parameters, residual dipolar couplings, hydrogen exchange rates, pK(a) values, etc.), (ii) databases for NMR restraints processed from original author depositions available from the Protein Data Bank, (iii) time-domain (raw) spectral data from NMR experiments used to assign spectral resonances and determine the structures of biological macromolecules and (iv) a database of one- and two-dimensional (1)H and (13)C one- and two-dimensional NMR spectra for over 250 metabolites. The BMRB website provides free access to all of these data. BMRB has tools for querying the archive and retrieving information and an ftp site (ftp.bmrb.wisc.edu) where data in the archive can be downloaded in bulk. Two BMRB mirror sites exist: one at the PDBj, Protein Research Institute, Osaka University, Osaka, Japan (bmrb.protein.osaka-u.ac.jp) and the other at CERM, University of Florence, Florence, Italy (bmrb.postgenomicnmr.net/). The site at Osaka also accepts and processes data depositions.

Abstract
We measured the effects of left ventricular circulatory assistance on ventricular mechanics of ejecting sheep hearts before and after global ischemia. Flows from left atrium to femoral artery ranged between 20 and 100 ml/kg/min during circulatory assistance. In preischemic, ejecting hearts increasing flow through the left ventricular assist device progressively decreased stroke volume, end-diastolic volume, and circumferential systolic wall stress, but only slightly decreased end-systolic volume. In postischemic, ejecting hearts left ventricular assistance progressively and substantially decreased both end-diastolic volume and end-systolic volume; at high flows, end-systolic volume returned to the normal range of preischemic hearts. High flows through the assist device also shifted end-systolic points of pressure-volume loops leftward and increased the stroke work/end-diastolic volume ratio in ejecting postischemic hearts; these observations raise the possibility that left ventricular circulatory assistance acutely improves myocardial contractility of postischemic hearts.

Abstract
In 10 patients, cardiopulmonary bypass decreased the number of fibrinogen binding sites from 31,730 +/- 12,802 per platelet to 18,590 +/- 9,644 per platelet. Bypass also decreased the amount of the platelet membrane glycoprotein IIIa, which is part of the fibrinogen receptor complex, from 17.1 +/- 3.6 ng/10(9) platelets to 12.9 +/- 4.7. The fibrinogen binding constant did not change. Platelet sensitivity to adenosine diphosphate did not change; however, template bleeding times increased from 5.2 +/- 1.5 minutes before bypass to 8.5 +/- 2.3 minutes after bypass. Analysis of detergent washings from the perfusion circuit after bypass in five patients indicated that platelet material remains attached to the surface as membrane fragments and degranulated platelets. These data further elucidate the mechanism of platelet loss and dysfunction during cardiopulmonary bypass and highlight the importance of platelet membrane fibrinogen receptors and surface adsorbed fibrinogen in this process.

Abstract
Extracorporeal membrane oxygenation uses peripherally placed cannulas and a streamlined circuit without a venous reservoir. This study tests the flow dynamics of venous catheters connected without a reservoir directly to a centrifugal pump. During in vitro testing, a 30 cm segment of collapsible tubing interposed between the reservoir and pump simulates the vein. In five sheep, flow was measured between catheters placed in the right atrium and inferior vena cava from peripheral sites. Catheter tip design (four types) does not affect flow within a simulated vein in vitro. Maximum pump flow is independent of filling pressures (6 to 21 mm Hg) in vitro and in vivo when the catheter tip is in a tank reservoir or the right atrium. However, when the catheter tip is within a collapsible segment or in the inferior vena cava, maximal flow is significantly influenced by filling pressure (6 to 18 mm Hg) and by the ratio of catheter outer diameter to venous diameter. At all filling pressures, maximal flow in vivo is significantly reduced when this ratio is greater than 0.5. During extracorporeal membrane oxygenation, central venous pressure and catheter/vein ratio, not catheter size alone, control flow through peripheral venous catheters.

Abstract
Extracorporeal membrane oxygenation (ECMO) reduces the systolic stress integral (SSI) in the normal left ventricle. We tested the hypothesis that the SSI does not decrease in poorly contracting, dilated, ejecting hearts during ECMO. In 14 sheep, four pairs of ultrasonic crystals measured changes in left ventricular (LV) wall thickness and three LV diameters. Volume calculations were validated by balloon distention of the ventricles after death (slope = 0.85; r = 0.85). SSI was measured during ECMO flows of 20 to 100 ml/kg/min in both normal and dilated, poorly contracting hearts produced by 30 minutes of warm ischemia. After warm ischemia, end-systolic elastance, an index of contractility, decreased from 8.3 +/- 0.6 mm Hg/ml to 2.9 +/- 0.4 mm Hg/ml (p = 0.001) and peak systolic pressure decreased from 47.4 +/- 0.7 mm Hg to 37.5 +/- 0.08 mm Hg (p = 0.01). In normal hearts, as ECMO flow increased, SSI decreased from 10.5 +/- 2.2 mm Hg.sec to 7.7 +/- 0.8 mm Hg.sec at 60 ml/kg/min (p = 0.001). However, in postischemic hearts, SSI progressively increased from 6.6 +/- 0.3 mm Hg.sec before ECMO to 12.4 +/- 1.8 mm Hg.sec at ECMO = 100 ml/kg/min. These studies indicate that the initial effect of ECMO on the poorly contracting, dilated heart increases LV wall stress and that the increase in stress is proportional to ECMO flow. The increase in stress is primarily due to an increase in afterload, which more than offsets decreases in systolic and diastolic volumes.

Abstract
The role of platelet fibrinogen receptors and platelet-protein interaction in platelet consumption during simulated cardiopulmonary bypass was investigated. In five recirculation experiments, with whole blood, the platelet count fell to 13% of initial values and in two experiments, with blood from patients with Bernard-Soulier syndrome, to 3% of normal values. However, in three experiments with blood from the patients with Glanzmann's thrombasthenia, the platelet count decreased to 69% of initial values. The extent of platelet consumption in normal blood was diminished to only 72% by addition of 0.5 microM prostaglandin E1 (PGE1) (5 experiments) and to 80% by precoating surfaces of the circuit with 2.5% human albumin (5 experiments). beta-Thromboglobulin antigen (beta TG) loss from platelets was associated with thrombocytopenia. The extent of beta TG loss was significantly reduced by the addition of PGE1 to blood or precoating surfaces with albumin. Proteins adsorbed on the surface of the circuit exposed to normal blood were removed with 0.5% Triton X-100. Some of these proteins were identified to be glycoprotein IIIa (GPIIIa) (3.4-4.3 micrograms/ml), beta TG (1.0-1.6 micrograms/ml), and fibrinogen (1.9-3.7 micrograms/ml). The amount of GPIIIa recovered in the Triton X-100 eluates correlated with the number of platelets lost during recirculation. These studies indicate that exposure of fibrinogen receptors associated with GPIIb-GPIIIa complex contributes to platelet consumption during cardiopulmonary bypass.

Abstract
Cardiopulmonary bypass, especially when prolonged, may result in hemostatic failure and pulmonary dysfunction, which has been attributed to changes in platelets and leukocytes, respectively. It has been well documented that contact of blood with synthetic surfaces causes platelet activation. In this report, we explore mechanisms of the activation of neutrophils during simulated in vitro extracorporeal circulation and document the release of neutrophil lactoferrin and elastase during clinical cardiopulmonary bypass (CCB). Inhibition in the simulated circuit by prostaglandin E1 (PGE1) and lidocaine suggests different mechanisms for release of neutrophil-specific proteins. During CCB with a bubble oxygenator it was observed that platelet counts fell to 42% +/- 2% of baseline. In addition, beta-thromboglobulin antigen (beta TG), a platelet-specific, alpha-granule protein marker reflecting the release reaction, increased from 0.15 +/- 0.05 to 0.84 +/- 0.11 microgram/mL. Neutrophil counts decreased to 67% +/- 7% of prebypass levels but then gradually rose as bypass continued. Both lactoferrin, a neutrophil-specific granule marker, and neutrophil elastase, an azurophilic granule marker, increased in plasma threefold to 1.66 +/- 0.33 micrograms/mL and 1.65 +/- 0.68 microgram/mL, respectively, just before bypass was stopped. When fresh heparinized human blood was recirculated within an extracorporeal membrane oxygenator bypass circuit for 120 minutes, plasma beta-TG rose to 5.13 micrograms/mL, lactoferrin increased from 0.13 +/- 0.04 to 1.62 +/- 0.22 micrograms/mL, and neutrophil elastase rose from 0.05 +/- 0.02 to 1.86 +/- 0.41 micrograms/mL. At 120 minutes, lidocaine (100 mumol/L), which inhibits neutrophil activation, delayed release of lactoferrin (1.33 +/- 0.26 micrograms/mL) and markedly inhibited release of elastase (0.24 +/- 0.05 microgram/mL) but did not inhibit release of beta-TG antigen (5.66 micrograms/mL at 120 minutes). PGE1 (0.3 mumol/L) inhibited significantly the release of beta-TG (0.31 microgram/mL) and elastase (0.52 +/- 0.11 microgram/mL) and attenuated the release of lactoferrin (1.57 +/- 0.45 micrograms/mL).
