Abstract

The Borexino detector has convincingly shown its outstanding performances in the low energy, sub-MeV regime through its unprecedented accomplishments in the solar and geo-neutrinos detection. These performances make it the ideal tool to accomplish a state-of-the-art experiment able to test unambiguously the long-standing issue of the existence of a sterile neutrino, as suggested by the several anomalous results accumulated over the past two decades, i.e. the outputs of the LSND and Miniboone experiments, the results of the source calibration of the two Gallium solar neutrino experiments, and the recently hinted reactor anomaly. The SOX project will exploit two sources, based on Chromium and Cerium, respectively, which deployed under the experiment, in a location foreseen on purpose at the time of the construction of the detector, will emit two intense beams of neutrinos (Cr) and anti-neutrinos (Ce). Interacting in the active volume of the liquid scintillator, each beam would create an unmistakable spatial wave pattern in case of oscillation of the νe (or ν̅e) into the sterile state: such a pattern would be the smoking gun proving the existence of the new sterile member of the neutrino family. Otherwise, its absence will allow setting a very stringent limit on its existence.

Abstract

Background: Facebook is increasingly being used as part of mass media campaigns in public health, including the Make Healthy Normal (MHN) campaign in New South Wales, Australia. Therefore, it is important to understand what role Facebook can play in mass media campaigns and how best to use it to augment or amplify campaign effects. However, few studies have explored this. Objective: This study aimed to investigate usage of and engagement with the MHN Facebook page and to identify influential factors in driving engagement with the page. Methods: We examined both post-level and page-level analytic data from Facebook from the campaign’s launch in June 2015 to September 2017. For post-level data, we conducted a series of negative binomial regressions with four different outcome measures (likes, shares, comments, post consumers), including some characteristics of Facebook posts as predictors. We also conducted time series analyses to examine associations between page-level outcomes (new page likes or “fans” and number of engaged users) and different measures of exposure to the page (number of unique users reached and total count of impressions) and to television advertising. Results: Of the 392 posts reviewed, 20.7% (n=81) received a paid boost and 58.9% (n=231) were photo posts. We found that posts that received a paid boost reached significantly more users and subsequently received significantly more engagement than organic (unpaid) posts (P<.001). After adjusting for reach, we found the effect of being paid was incremental for all outcome measures for photos and links, but not videos. There were also associations between day of the week and time of post and engagement, with Mondays generally receiving less engagement and posts on a Friday and those made between 8 AM and 5 PM receiving more. At the page level, our time series analyses found that organic impressions predicted a higher number of new fans and engaged users, compared to paid impressions, especially for wom

Abstract

Facebook is used as part of public health communication efforts but little evidence is available on why people engage with health-related Facebook pages and what content appeals to them. This study aimed to investigate user perceptions of and experience with the Make Healthy Normal (MHN) Facebook page, part of a government campaign to address overweight and obesity in adults in New South Wales, Australia. This sequential mixed methods study comprised an online survey (n = 591) and six focus groups (n = 33) of Facebook users, including both fans (i.e., users who have “liked” the MHN page) and non-fans. We analyzed the online survey descriptively and employed inductive thematic analysis for the focus groups, integrating the two data sources at the stage of interpretation. Our results show that MHN and similar health pages are in demand but that there are a number of contextual and content-related factors that are critical in determining user engagement and over which page administrators have varying levels of influence. Contextual factors, including the drivers for user engagement and Facebook user practices, can be leveraged or managed to influence user engagement but they cannot be controlled. On the contrary, content factors, like the nature of posts, post presentation, and post subject, can be directly influenced by page administrators. Policymakers and practitioners can use these findings to inform the design and operation of their own Facebook pages and should look to conduct and disseminate robust evaluation of their pages to improve user satisfaction and engagement.

Abstract

The SOX (Short distance neutrino Oscillations with BoreXino) project aims at testing the light sterile neutrino hypothesis. To do so, two artificials sources of antineutrinos and neutrinos respectively will be consecutively deployed at the Laboratori Nazionali del Gran Sasso (LNGS) in close vicinity to Borexino, a large liquid scintillator detector. This document reports on the 0, source production and transportation. The source should exhibit a long lifetime and a high decay energy, a requirement fullfilled by the Ce-144-Pr-144 pair at secular equilibrium. It will be produced at FSUE "Mayak" PA using spent nuclear fuel. It will then be shielded and packed according to international regulation and shipped to LNGS across Europe. Knowledge of the Cerium antineutrino generator (CeANG) parameters is crucial for SOX as it can strongly impact the experiment sensitivity. Several apparatuses are being used or designed to characterize CeANG activity, radioactive emission and content. An overview of the measurements performed so far is presented here.

International audience; In the recent years, the Borexino detector has proven its outstanding performances in detecting neutrinos and antineutrinos in the low energy regime. Consequently, it is an ideal tool to investigate the existence of sterile neutrinos, whose presence has been suggested by several anomalies over the past two decades. The SOX (Short distance neutrino Oscillations with boreXino) project will investigate the presence of sterile neutrinos placing a neutrino and an antineutrino sources in a location under the detector foreseen for this purpose since the construction of Borexino. Interacting in the detector active volume, each beam would create a well detectable spatial wave pattern in case of oscillation of neutrino or antineutrino in a sterile state. Otherwise, the experiment will set a very stringent limit on the existence of a sterile state.

Abstract

International audience; SOX (Short distance neutrino Oscillations with BoreXino) is a new experiment that takes place at the Laboratori Nazionali del Gran Sasso (LNGS) and it exploits the Borexino detector to study the neutrino oscillations at short distance. In different phases, by using two artificial sources 51Cr and 144Ce-144Pr, neutrino and antineutrino fluxes of measured intensity will be detected by Borexino in order to observe possible neutrino oscillations in the sterile state. In this paper an overview of the experiment is given and one of the two calorimeters that will be used to measure the source activity is described. At the end the expected sensitivity to determine the neutrino sterile mass is shown.

The SOX experiment will use a $^{144}Ce-^{144}Pr$ antineutrino generator placed 8.5~m below the Borexino liquid scintillator detector. In view of the SOX experiment, a precise knowledge of the energy response and the spatial reconstruction of the antineutrino events is very important. Consequently, a calibration campaign of the Borexino detector is foreseen before the beginning of the SOX data taking.

Abstract

Several observed anomalies in the neutrino sector could be explained by a fourth (sterile) neutrino with a squared mass difference in the order of 1eV 2 to the other three standard neutrinos. This hypothesis can be tested with an artificial kCi antineutrino (Ce-144/Pr-144) source deployed near or inside a large low background detector like Borexino. The SOX project (short baseline neutrino oscillation with Borexino) aims for the detection of sterile neutrinos and offers the almost unique possibility to observe the characteristic antineutrino oscillation pattern within the detector. The concept is summarized whereby particular focus is given to the antineutrino spectrum calculation.

Abstract

Abstract: Spectroscopic ellipsometry has been used to extract the optical indices of blend organic donor:ZnO (1:2) thin films. Four different donor molecules are investigated in this study: P3HT, PCPDTBT, PTB7 and DTS(PTTh2)2. Using these optical indices as input parameters, the optical performances and the color range for human eyes of donor:ZnO (1:2) hybrid organic–inorganic solar cells have been investigated through optical simulations. These calculations suggest that a tradeoff between reflectance for human eyes and photonic absorption of the AM1.5 spectrum can be reached depending on the composition of the active layer. While the total device reflectance in the visible range is closely correlated to the photonic absorption in the case of a high band gap semiconducting material, a tradeoff is easier to obtain in the case of low band gap semi-conducting materials. Finally, we show that the color range of devices depends both on the active layer compositions and the geometrical parameters of the cells. [Copyright &y& Elsevier]

Abstract

International audience; Borexino is an unsegmented neutrino detector operating at LNGS in central Italy. The experiment has shown its performances through its unprecedented accomplishments in the solar and geoneutrino detection. These performances make it an ideal tool to accomplish a state- of-the-art experiment able to test the existence of sterile neutrinos (SOX experiment). For both the solar and the SOX analysis, a good understanding of the detector response is fundamental. Consequently, calibration campaigns with radioactive sources have been performed over the years. The calibration data are of extreme importance to develop an accurate Monte Carlo code. This code is used in all the neutrino analyses. The Borexino-SOX calibration techniques and program and the advances on the detector simulation code in view of the start of the SOX data taking are presented. (1)

Abstract

International audience; In order to perform a resolutive measurement to clarify the neutrino anomalies and to observe possible short distance neutrino oscillations, the SOX (Short distance neutrino Oscillations with BoreXino) experiment is under construction. In the first phase, a 100 kCi (144)Ce-(144)Pr antineutrino source will be placed under the Borexino detector at the Laboratori Nazionali del Gran Sasso (LNGS), in center of Italy, and the rate measurement of the antineutrino events, observed by the very low radioactive background Borexino detector, will be compared with the high precision (< 1%) activity measurement performed by two calorimeters. The source will be embedded in a 19 mm thick tungsten alloy shield and both the calorimeters have been conceived for measuring the thermal heat absorbed by a water flow. In this report the design of the calorimeters will be described in detail and very preliminary results will be also shown.

Abstract

International audience; The aim of the SOX-Borexino project is to verify or falsify the existence of eV-scale sterile neutrinos. The existence of sterile neutrinos is suspected because of several anomalies, which were observed in previous experiments. A ~3.7 PBq electron antineutrino source made of$^{144}$Ce will be installed below the Borexino detector at LNGS, Italy, to search for short-baseline oscillations of active-to-sterile neutrinos within the detector volume. Source delivery and beginning of data acquisition is planned for end of 2016, preliminary results are expected already in 2017.

Abstract

International audience; The Borexino detector has convincingly shown its outstanding performances in the low energy regime through its accomplishments in the observation and study of the solar and geo neutrinos. It is then an ideal tool to perform a state of the art source-based experiment for testing the longstanding hypothesis of a fourth sterile neutrino with ~ eV(2) mass, as suggested by several anomalies accumulated over the past three decades in source, reactor, and accelerator-based experiments. The SOX project aims at successively deploying two intense radioactive sources, made of Cerium (antineutrino) and Chromium (neutrino), respectively, in a dedicated pit located beneath the detector. The existence of such an ~ eV(2) sterile neutrino would then show up as an unambiguous spatial and energy distortion in the count rate of neutrinos interacting within the active detector volume. This article reports on the latest developments about the first phase of the SOX experiment, namely CeSOX, and gives a realistic projection of CeSOX sensitivity to light sterile neutrinos in a simple (3+1) model.

Abstract

Methylphenidate (MPH) is a central nervous system stimulant that is mainly used for Attention-Deficit/Hyperactivity Disorder (ADHD). It is well known that there is a high rate of ADHD misdiagnosis, leading to a great number of neurotypical children chronically exposed to MPH in early periods of life. This increase raises concern about possible long-lasting effects of this exposure. We aimed to evaluate whether exposure to MPH during childhood might impact adult behavioral pattern. For this purpose, we used zebrafish as a translational model considering its robustness as experimental model and fast life cycle. Fish were exposed during juvenile period (from 30 to 60 post-natal day) at MPH therapeutic concentration (2 mg L -1 ), and behavioral tests were performed at fish adulthood (120 post-natal day). MPH provoked slight anxiolytic-like effects and hyperlocomotion, and no differences on sociability and cortisol levels were observed. Moreover, sex did not affect any of the parameters evaluated. These results demonstrate that early chronic exposure to MPH leads to neurobehavioral adaptations that persist into adulthood in zebrafish regardless of sex, suggesting that the misuse of MPH during childhood and adolescence can alter neurobehavioral plasticity and these alterations might persist until adulthood., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 Elsevier B.V.

32. Generating Engagement on the Make Healthy Normal Campaign Facebook Page: Analysis of Facebook Analytics.

Abstract

Background: Facebook is increasingly being used as part of mass media campaigns in public health, including the Make Healthy Normal (MHN) campaign in New South Wales, Australia. Therefore, it is important to understand what role Facebook can play in mass media campaigns and how best to use it to augment or amplify campaign effects. However, few studies have explored this., Objective: This study aimed to investigate usage of and engagement with the MHN Facebook page and to identify influential factors in driving engagement with the page., Methods: We examined both post-level and page-level analytic data from Facebook from the campaign's launch in June 2015 to September 2017. For post-level data, we conducted a series of negative binomial regressions with four different outcome measures (likes, shares, comments, post consumers), including some characteristics of Facebook posts as predictors. We also conducted time series analyses to examine associations between page-level outcomes (new page likes or "fans" and number of engaged users) and different measures of exposure to the page (number of unique users reached and total count of impressions) and to television advertising., Results: Of the 392 posts reviewed, 20.7% (n=81) received a paid boost and 58.9% (n=231) were photo posts. We found that posts that received a paid boost reached significantly more users and subsequently received significantly more engagement than organic (unpaid) posts (P<.001). After adjusting for reach, we found the effect of being paid was incremental for all outcome measures for photos and links, but not videos. There were also associations between day of the week and time of post and engagement, with Mondays generally receiving less engagement and posts on a Friday and those made between 8 AM and 5 PM receiving more. At the page level, our time series analyses found that organic impressions predicted a higher number of new fans and engaged users, compared to paid impressions, especially for women. We also found no association between television advertising and engagement with the Facebook page., Conclusions: Our study shows that paying for posts is important for increasing their reach, but that page administrators should look to maximize organic reach because it is associated with significantly higher engagement. Once reach is accounted for, video posts do not benefit from being paid, unlike the other post types. This suggests that page administrators should carefully consider how they use videos as part of a Facebook campaign. Additionally, the lack of association between television advertising and engagement suggests that future campaigns consider how best to link different channels to amplify effects. These results highlight the need for ongoing evaluation of Facebook pages if administrators are to maximize engagement., (©James Kite, Anne Grunseit, Vincy Li, John Vineburg, Nathan Berton, Adrian Bauman, Becky Freeman.

Abstract

The present study reports on the use of three types of polyhedral oligomeric silsesquioxanes (POSS) nanoparticles with various organic substituents as fillers in a fluoroelastomer (FKM). A series of/POSS elastomer composite thin films is prepared. Microstructural SEM/TEM (scanning electron microscopy/transmission electron microscopy) imaging reveals a dispersion state allowing the presence of micron-sized domains. The influence of POSS content is studied in order to optimize thermal stability and mechanical properties of the composite thin films. Both POSS-A (with an acryloyl functional group and seven isobutyl substituents) and POSS-P (with eight phenyl substituents) lead to higher thermal stability and modulus of the composites, with respect to the unfilled FKM terpolymer matrix. covalent grafting of POSS-A onto the FKM network is found to play a critical role. Enhanced storage modulus in the rubbery plateau region (+210% at 200 °C for 20 phr) suggests that POSS-A is particularly suitable for high temperature applications.

34. Selective dispersion of large-diameter semiconducting single-walled carbon nanotubes with pyridine-containing copolymers.

Author

Abstract

The purity of single-walled carbon nanotubes (SWNTs) is a key parameter for their integration in electronic, optoelectronic and photonic devices. Samples of pristine SWNTs are inhomogeneous in terms of electric behavior and diameter and contain a variety of amorphous carbon and catalyst residues. To obtain high performance devices, purification of SWNTs is required. Conjugated polymers have emerged as efficient solubilizing and sorting agents for small diameter SWNTs (HiPco tubes, 0.7 nm<Ø<1.1 nm). Nevertheless, reports on polymers able to efficiently sort large diameter SWNTs with Ø>1.1 nm are lacking. Several pyridine-containing copolymers were synthesized for this purpose and showed efficient and selective extraction of semiconducting large diameter SWNTs (PLV tubes, Ø>1.1 nm). High concentration and high purity suspensions are obtained without the use of ultracentrifugation, which gives an up-scaling potential of the method. The emission wavelength is in near infrared region around 1550 nm and fits with broadly used telecommunication wavelength window. The processes taking place at the interface were simulated by a newly designed hybrid coarse-grain model combining density functional theory and geometrical calculation to yield insights into the wrapping processes with an unprecedented level of details for such large diameter SWNTs., (© 2013 WILEY-VCH Verlag GmbH & Co.

Abstract

A series of oligofluorenes was synthesized and used as a SWNT selecting template to study the chain length effect on SWNTs dispersions in toluene. The octamer exhibits the same selectivity as the corresponding polymer. Nevertheless, SWNT/oligomer complexes are unstable, which allows fast exchange of the oligomer with a coating polymer., (This journal is © The Royal Society of Chemistry 2012)

36. Poly(bisthiophene-carbazole-fullerene) double-cable polymer as new donor-acceptor material: preparation and electrochemical and spectroscopic characterization.

Author

Berton N, Fabre-Francke I, Bourrat D, Chandezon F, and Sadki S

Abstract

A new donor-acceptor dyad, namely, a 3,6-bis(thiophen-2-yl)carbazole derivative bearing a C(60) fullerene as a side group (BTC-F), was prepared and characterized. Electropolymerization of BTC-F leads to the formation of a donor-acceptor double-cable polymer (PBTC-F) with high fullerene content (63 wt %) corresponding to one C(60) per polymer repeat unit. The electronic properties of BTC-F and PBTC-F were studied by electrochemical and spectroscopic techniques. Photoluminescence quenching is observed in diluted solutions of BTC-F compared to the nongrafted monomer BTC indicating that an intramolecular charge transfer takes place between the two components of the dyad. The positions of the HOMO and LUMO levels of the monomer and the polymer were accurately determined by differential pulse voltammetry (DPV). The LUMO energy level of the fullerene moiety in BTC-F lies at 3.7 eV below the vacuum level, i.e., slightly higher than corresponding levels of C(60) and PCBM. DPV characterization of PBTC-F indicates little ground state interaction between the pi-conjugated main chain and the C(60) side groups and a high donor HOMO-acceptor LUMO gap of 1.47 eV.

37. A predictive approach of the influence of the operating parameters on the size of polymer particles synthesized in a simplified microfluidic system.

Author

Abstract

Monodisperse and size-controlled spherical polymer particles were synthesized by in situ photopolymerization of O/W monomer emulsions. Monomer droplets were produced without surfactant or pretreatment at a needle tip in a simplified axisymmetric microfluidic device. The effect of the viscosity of the continuous phase on the particle size was studied. The system operated in the dripping mode, at a low Reynolds number. A dimensionless master curve describes the particle diameter as a function of the needle inner diameter as well as velocity and viscosity ratios of continuous and dispersed phases. An empirical law predicts the particle size. The normalized particle diameter depends upon the ratio of the capillary numbers of continuous and dispersed phases with an exponent equal to -0.22.

Abstract

We are focused on understanding the mechanisms underlying eukaryotic gene regulation, using the human progesterone receptor (PR) and its interactions with its DNA response elements as a model system. An understanding of PR function is complicated by the presence of two transcriptionally distinct isoforms, an 83 kDa A-receptor (PR-A) and a 99 kDa B-receptor (PR-B). The two isoforms are identical except the B-receptor contains an additional 164 residues at its N-terminus. As a first step toward understanding the principles by which the two isoforms assemble at complex promoters, we examined the energetics of PR-B self-association using sedimentation velocity and sedimentation equilibrium methods. Full-length human PR-B was purified to 95% homogeneity from baculovirus-infected insect cells. Using a fluorescence hormone binding assay, we determined the purified protein to be highly active in its ability to bind ligand. Sedimentation velocity studies of hormone-bound PR-B at pH 8.0, 4 degrees C, and 50 mM NaCl demonstrate that it undergoes a concentration-dependent change in its sedimentation coefficient, existing as a 4.0S species at submicromolar concentrations but forming a 5.7S species at higher concentrations. These results strongly suggest that PR-B undergoes self-association in the micromolar range. This hypothesis was examined rigorously using sedimentation equilibrium. Global analysis of the sedimentation equilibrium data demonstrated that PR-B self-association was well described by a monomer-dimer model with a dimerization free energy of -7.2 +/- 0.7 kcal/mol. The role of NaCl in regulating PR-B dimerization was examined by carrying out sedimentation velocity and equilibrium studies under high salt conditions. At 300 mM NaCl, PR-B is exclusively monomeric in the micromolar range, thus revealing a significant ionic contribution to the assembly energetics. Further, the monomer sediments as a structurally homogeneous, but highly asymmetric, 4.0S species. Limited proteolysis of PR-B demonstrated that the hydrodynamic asymmetry is due in part to an extended, nonglobular conformation localized to the N-terminal region of PR-B. In contrast, the DNA binding domain (DBD) and hormone binding domain (HBD) exist as independent structural units, and the activation function N-terminal to the DBD (AF-1) shows moderate structure. These results represent the first rigorous analysis of the self-assembly energetics of an intact nuclear receptor and suggest that PR function is more complex than envisioned by traditional models.

Abstract

Terminase enzymes mediate genome "packaging" during the reproduction of DNA viruses. In lambda, the gpNu1 subunit guides site-specific assembly of terminase onto DNA. The structure of the dimeric DNA binding domain of gpNu1 was solved using nuclear magnetic resonance spectroscopy. Its fold contains a unique winged helix-turn-helix (wHTH) motif within a novel scaffold. Surprisingly, a predicted P loop ATP binding motif is in fact the wing of the DNA binding motif. Structural and genetic analysis has identified determinants of DNA recognition specificity within the wHTH motif and the DNA recognition sequence. The structure reveals an unexpected DNA binding mode and provides a mechanistic basis for the concerted action of gpNu1 and Escherichia coli integration host factor during assembly of the packaging machinery.

Abstract

Terminase enzymes are common to double-stranded DNA viruses. These enzymes "package" the viral genome into a pre-formed capsid. Terminase from bacteriophage lambda is composed of gpA (72.4 kDa) and gpNu1 (20.4 kDa) subunits. We have described the expression and biochemical characterization of gpNu1DeltaK100, a construct comprising the N-terminal 100 amino acids of gpNu1 (Yang, Q., de Beer, T., Woods, L., Meyer, J., Manning, M., Overduin, M., and Catalano, C. E. (1999) Biochemistry 38, 465-477). Here we present a biophysical characterization of this construct. Thermally induced loss of secondary and tertiary structures is fully reversible. Surprisingly, although loss of tertiary structure is cooperative, loss of secondary structure is non-cooperative. NMR and limited proteolysis data suggest that approximately 30 amino acids of gpNu1DeltaK100 are solvent-exposed and highly flexible. We therefore constructed gpNu1DeltaE68, a protein consisting of the N-terminal 68 residues of gpNu1. gpNu1DeltaE68 is a dimer with no evidence of dissociation or further aggregation. Thermally induced unfolding of gpNu1DeltaE68 is reversible, with concomitant loss of both secondary and tertiary structure. The melting temperature increases with increasing protein concentration, suggesting that dimerization and folding are, at least in part, coupled. The data suggest that gpNu1DeltaE68 represents the minimal DNA binding domain of gpNu1. We further suggest that the C-terminal approximately 30 residues in gpNu1DeltaK100 adopt a pseudo-stable alpha-helix that extends from the folded core of the protein. A model describing the role of this helix in the assembly of the packaging apparatus is discussed.

Abstract

The terminase enzyme from bacteriophage lambda is responsible for the insertion of a dsDNA genome into the confines of the viral capsid. The holoenzyme is composed of gpA and gpNu1 subunits in a gpA(1) x gpNu1(2) stoichiometry. While genetic studies have described regions within the two proteins responsible for DNA binding, capsid binding, and subunit interactions in the holoenzyme complex, biochemical characterization of these domains is limited. We have previously described the cloning, expression, and biochemical characterization of a soluble DNA binding domain of the terminase gpNu1 subunit (Met1 to Lys100) and suggested that the hydrophobic region spanning Lys100 to Pro141 defines a domain responsible for self-association interactions, and that is important for cooperative DNA binding [Yang et al. (1999) Biochemistry 38, 465-477]. We further suggested that the genetically defined gpA-interactive domain in the C-terminal half of the protein is limited to the C-terminal approximately 40 amino acids of gpNu1. Here we describe the cloning, expression, and biochemical characterization of gpNu1DeltaP141, a deletion mutant of gpNu1 that comprises the DNA binding domain and the putative hydrophobic self-assembly domain of the full-length protein. Purified gpNu1DeltaP141 shows a strong tendency to aggregate in solution; However, the protein remains soluble in 0.4 M guanidine hydrochloride, and circular dichroism (CD) and fluorescence spectroscopic studies demonstrate that the protein is folded under these conditions. Moreover, CD spectroscopy and thermally induced unfolding studies suggest that the DNA binding domain and the self-association domain represent independent folding domains of gpNu1DeltaP141. The mutant protein interacts weakly with the gpA subunit, but does not form a catalytically competent holoenzyme complex, suggesting that the C-terminal 40 residues are important for appropriate subunit interactions. Importantly, gpNu1DeltaP141 binds DNA tightly, but with less specificity than does full-length protein, and the data suggest that the C-terminal residues are further required for specific DNA binding activity. The implications of these results in the assembly of a functional holoenzyme complex are discussed.

Abstract

The ability of recombinant human Hb (rHb1.1), which is being developed as an oxygen therapeutic, to support metabolism was measured by in vivo 31P-NMR surface coil spectroscopy of the rat abdomen in control animals and in animals subjected to isovolemic exchange transfusion to hematocrit of <3% with human serum albumin or 5 g/dl rHb1.1. No significant changes in metabolite levels were observed in control animals for up to 6 h. The albumin-exchange experiments, however, resulted in a more than eightfold increase in Pi and a 50% drop in phosphocreatine and ATP within 40 min. The tissue pH dropped from 7.4 to 6.8. The decrease in high-energy phosphates obeyed Michaelis-Menten kinetics, with a Michaelis-Menten constant of 3% as the hematocrit at which a 50% drop in high-energy phosphates was observed. Exchange transfusion with rHb1.1 resulted in no significant drop in high-energy phosphates, no rise in Pi, and no change in tissue pH from 7.35 +/- 0.15 for up to 5 h after exchange. By these criteria, rHb1.1 at a plasma Hb concentration of approximately 5 g/dl after total exchange transfusion was able to sustain energy metabolism of gut tissue at levels indistinguishable from control rats with a threefold higher total Hb level in erythrocytes.
