Shock initiation of multi-component insensitive PBX explosives: Experiments and MC-DZK mesoscopic reaction rate model.

J Hazard Mater 2019 Feb 10;369:62-69. Epub 2019 Feb 10.

The State Key Laboratory of Explosion Science and Technology, Beijing Institute of Technology, Beijing, 100081, China.

To facilitate the pre-estimation and optimization of the prescription design of a multi-component polymer bonded explosive (PBX), a multicomponent mesoscopic reaction rate model (MC-DZK model) is developed to predicate preferably the influence of both the explosive components and the particle size of on the shock initiation. All the parameters in the model are determined directly by the parameters in the DZK model for each explosive component. Furthermore, for the multicomponent insensitive explosive PBXC10 (70% TATB, 25% HMX, and 5% Kel-F800 by weight) with different explosive particle sizes, both shock initiation experiments and corresponding numerical simulations are performed, and there is satisfactory agreement between the numerical results and the available experimental data.

The Origin of Intracranial Pressure Causing Brainstem Hemorrhages.

Neurocrit Care 2019 Feb 15. Epub 2019 Feb 15.

Division of Neurocritical Care and Hospital Neurology, Mayo Clinic, 200 First Street SW, Rochester, MN, 55905, USA.

The origin of secondary brainstem hemorrhages following an acute expansive hemispheric lesion has been attributed to Henri Duret, who proposed that hemorrhaging was caused by a shock wave through the cerebral spinal fluid. However, other experiments have shown important findings correlating brainstem hemorrhages to arterial hemorrhages. Animal studies found that the rapidity of expansion of a lesion would be crucial in producing these lesions, but there was no consistent correlation with paratentorial grooving so commonly seen with increased intracranial pressure.

Impact of a Heat Shock Protein Impurity on the Immunogenicity of Biotherapeutic Monoclonal Antibodies.

Pharm Res 2019 Feb 15;36(4):51. Epub 2019 Feb 15.

School of Biological Sciences, Faculty of Biology Medicine and Health Manchester Academic Health Science Centre, The University of Manchester, Michael Smith Building Oxford Road, Manchester, M13 9PT, UK.

Purpose: Anti-drug antibodies can impair the efficacy of therapeutic proteins and, in some circumstances, induce adverse health effects. Immunogenicity can be promoted by aggregation; here we examined the ability of recombinant mouse heat shock protein 70 (rmHSP70) - a common host cell impurity - to modulate the immune responses to aggregates of two therapeutic mAbs in mice.

Methods: Heat and shaking stress methods were used to generate aggregates in the sub-micron size range from two human mAbs, and immunogenicity assessed by intraperitoneal exposure in BALB/c mice. Read More

Fhit-Fdxr interaction in the mitochondria: modulation of reactive oxygen species generation and apoptosis in cancer cells.

Cell Death Dis 2019 Feb 15;10(3):147. Epub 2019 Feb 15.

Department of Cancer Biology and Genetics, The Ohio State University Comprehensive Cancer Center, Columbus, OH, 43210, USA.

Fhit protein is lost in cancers of most, perhaps all, cancer types; when restored, it can induce apoptosis and suppress tumorigenicity, as shown in vitro and in mouse tumor models in vivo. Following protein cross-linking and proteomics analyses, we characterized a Fhit protein complex involved in triggering Fhit-mediated apoptosis. The complex includes the heat-shock chaperonin pair, HSP60/10, which is likely involved in importing Fhit into the mitochondria, where it interacts with ferredoxin reductase, responsible for transferring electrons from NADPH to cytochrome P450 via ferredoxin, in electron transport chain complex III.

Electronic address:

Sepsis is a bi-phasic inflammatory disease that threatens approximately 30 million lives and claims over 14 million annually, yet little is known regarding the molecular switches and pathways that regulate this disease. Here, we have described ABCF1, an ATP-Binding Cassette (ABC) family member protein, which possesses an E2 ubiquitin enzyme activity, through which it controls the Lipopolysaccharide (LPS)- Toll-like Receptor-4 (TLR4) mediated gram-negative insult by targeting key proteins for K63-polyubiquitination. Ubiquitination by ABCF1 shifts the inflammatory profile from an early phase MyD88-dependent to a late phase TRIF-dependent signaling pathway, thereby regulating TLR4 endocytosis and modulating macrophage polarization from M1 to M2 phase.

Proteasome inhibitor b-AP15 induces enhanced proteotoxicity by inhibiting cytoprotective aggresome formation.

Cancer Lett 2019 Feb 12. Epub 2019 Feb 12.

Department of Oncology-Pathology, Karolinska Institute, Stockholm, Sweden; Department of Medical and Health Sciences, Linköping University, Linköping, Sweden. Electronic address:

Proteasome inhibitors have been shown to induce cell death in cancer cells by triggering an acute proteotoxic stress response characterized by accumulation of poly-ubiquitinated proteins, ER stress and the production of reactive oxygen species. The aggresome pathway has been described as an escape mechanism from proteotoxicity by sequestering toxic cellular aggregates. Here we show that b-AP15, a small-molecule inhibitor of proteasomal deubiquitinase activity, induces poly-ubiquitin accumulation in absence of aggresome formation. Read More

Front Cell Dev Biol 2019 31;7. Epub 2019 Jan 31.

Department of Biochemistry and Biophysics, University of North Carolina School of Medicine, Chapel Hill, NC, United States.

Neuron-Glia related cell adhesion molecule (NrCAM) is a candidate autism risk factor that promotes axon guidance through cytoskeletal linkages in developing brain but its role in limbic circuitry has not been investigated. hybridization (ISH) and immunofluorescence staining showed that NrCAM is expressed in the developing amygdalar pathway of mouse embryos during outgrowth of projections in the stria terminalis, a major limbic tract that interconnects the central amygdala (CeA) with key targets in the bed nucleus of the stria terminalis (BNST). Analysis of fiber tracts in NrCAM mutant mice by Neurofilament protein immunohistochemistry showed pronounced defasciculation and misprojection of fibers in the ST. Read More

Multidrug-Resistant Complex Emerging as a Global, Diversifying Threat.

Front Microbiol 2019 31;10:44. Epub 2019 Jan 31.

Division of Infectious Diseases, Department of Medicine, Columbia University, New York, NY, United States.

The complex (ECC) includes common nosocomial pathogens capable of producing a wide variety of infections. Broad-spectrum antibiotic resistance, including the recent emergence of resistance to last-resort carbapenems, has led to increased interest in this group of organisms and carbapenem-resistant complex (CREC) in particular. Molecular typing methods based on heat-shock protein sequence, pulsed-field gel electrophoresis, comparative genomic hybridization, and, most recently, multilocus sequence typing have led to the identification of over 1069 ECC sequence types in 18 phylogenetic clusters across the globe.

Evidence for electron Landau damping in space plasma turbulence.

Nat Commun 2019 Feb 14;10(1):740. Epub 2019 Feb 14.

Department of Physics and Astronomy, University of Iowa, Iowa City, IA, 52242, USA.

How turbulent energy is dissipated in weakly collisional space and astrophysical plasmas is a major open question. Here, we present the application of a field-particle correlation technique to directly measure the transfer of energy between the turbulent electromagnetic field and electrons in the Earth's magnetosheath, the region of solar wind downstream of the Earth's bow shock. The measurement of the secular energy transfer from the parallel electric field as a function of electron velocity shows a signature consistent with Landau damping. Read More

The role of diffusion-driven pure climb creep on the rheology of bridgmanite under lower mantle conditions.

Sci Rep 2019 Feb 14;9(1):2053. Epub 2019 Feb 14.

University Lille, CNRS, INRA, ENSCL, UMR 8207 - UMET - Unité Matériaux et Transformations, Lille, F-59000, France.

The viscosity of Earth's lower mantle is poorly constrained due to the lack of knowledge on some fundamental variables that affect the deformation behaviour of its main mineral phases. This study focuses on bridgmanite, the main lower mantle constituent, and assesses its rheology by developing an approach based on mineral physics. Following and revising the recent advances in this field, pure climb creep controlled by diffusion is identified as the key mechanism driving deformation in bridgmanite. Read More

Punishment-Predictive Cues Guide Avoidance through Potentiation of Hypothalamus-to-Habenula Synapses.

Neuron 2019 Feb 7. Epub 2019 Feb 7.

Department of Fundamental Neuroscience, University of Lausanne, 1005 Lausanne, Switzerland; Inserm, UMR-S 839, 75005 Paris, France. Electronic address:

Throughout life, individuals learn to predict a punishment via its association with sensory stimuli. This process ultimately prompts goal-directed actions to prevent the danger, a behavior defined as avoidance. Neurons in the lateral habenula (LHb) respond to aversive events as well as to environmental cues predicting them, supporting LHb contribution to cue-punishment association. Read More

Venoarterial ECMO for Adults: JACC Scientific Expert Panel.

J Am Coll Cardiol 2019 Feb;73(6):698-716

Division of Cardiology, Icahn School of Medicine at Mount Sinai, New York, New York.

Venoarterial extracorporeal membrane oxygenation (ECMO) is a rescue therapy that can stabilize patients with hemodynamic compromise, with or without respiratory failure, for days or weeks. In cardiology, the main indications for ECMO include cardiac arrest, cardiogenic shock, post-cardiotomy shock, refractory ventricular tachycardia, and acute management of complications of invasive procedures. The fundamental premise underlying ECMO is that it is a bridge-to recovery, to a more durable bridge, to definitive treatment, or to decision. Read More
