Effects of a single transient transfection of Ten-eleven translocation 1 catalytic domain on hepatocellular carcinoma.

PLoS One 2018 14;13(12):e0207139. Epub 2018 Dec 14.

College of Pharmacy, Nanchang University, Nanchang, Jiangxi, P.R. China.

Tumor suppressor genes (TSGs), including Ten-eleven translocation 1 (TET1), are hypermethylated in hepatocellular carcinoma (HCC). TET1 catalytic domain (TET1-CD) induces genome-wide DNA demethylation to activate TSGs, but so far, anticancer effects of TET1-CD are unclear. Here we showed that after HCC cells were transiently transfected with TET1-CD, the methylation levels of TSGs, namely APC, p16, RASSF1A, SOCS1 and TET1, were distinctly reduced, and their mRNA levels were significantly increased and HCC cells proliferation, migration and invasion were suppressed, but the methylation and mRNA levels of oncogenes, namely C-myc, Bmi1, EMS1, Kpna2 and c-fos, were not significantly change.

Pre-harvest internalization and surface survival of Salmonella and Escherichia coli O157:H7 sprayed onto different lettuce cultivars under field and growth chamber conditions.

Int J Food Microbiol 2018 Dec 4;291:197-204. Epub 2018 Dec 4.

Department of Horticulture, University of Georgia, 2360 Rainwater Rd., Tifton, GA 31793-5766, USA.

Plant genotype has been advocated to have an important role in the fate of enteric pathogens residing in lettuce foliage. This study was therefore undertaken under the premise that different pathogen responses could occur in lettuce cultivars with cultivar selection being one of several hurdles in an overall strategy for controlling foodborne pathogens on field-grown produce. Up to eight lettuce cultivars ('Gabriella', 'Green Star', 'Muir', 'New Red Fire', 'Coastal Star', 'Starfighter', 'Tropicana', and 'Two Star') were examined in these experiments in which the plants were subjected to spray contamination of their foliage with pathogens.

The Drying Kinetics of Salt Solution Droplets: Water Evaporation Rates and Crystallisation.

J Phys Chem B 2018 Dec 14. Epub 2018 Dec 14.

The drying and crystallisation of solution droplets is a problem of broad relevance, determining the micro-structures of particles formed in spray drying, the phase of particles delivered by, for example, aerosol formulations for inhalation therapies, and the impact of aerosols on radiative forcing and climate. The ephemeral nature of free-droplets, particularly when considering the drying kinetics of droplets with highly volatile constituents, has often precluded the accurate measurement of transient properties such as droplet size and composition, preventing the robust assessment of predictive models of droplet drying rates, nucleation and crystallisation. Here, we report novel measurements of the drying kinetics of individual aqueous sodium chloride solution droplets using a comparative-kinetics electrodynamic balance to isolate and trap single aerosol droplets (radius ~ 25 µm).

Sublaminar organization of the human subplate: developmental changes in the distribution of neurons, glia, growing axons and extracellular matrix.

J Anat 2018 Dec 13. Epub 2018 Dec 13.

Croatian Institute for Brain Research, School of Medicine, University of Zagreb, Zagreb, Croatia.

The objective of this paper was to collect normative data essential for analyzing the subplate (SP) role in pathogenesis of developmental disorders, characterized by abnormal circuitry, such as hypoxic-ischemic lesions, autism and schizophrenia. The main cytological features of the SP, such as low cell density, early differentiation of neurons and glia, plexiform arrangement of axons and dendrites, presence of synapses and a large amount of extracellular matrix (ECM) distinguish this compartment from the cell-dense cortical plate (CP; towards pia) and large fiber bundles of external axonal strata of fetal white matter (towards ventricle). For SP delineation from these adjacent layers based on combined cytological criteria, we analyzed the sublaminar distribution of different microstructural elements and the associated maturational gradients throughout development, using immunocytochemical and histological techniques on postmortem brain material (Zagreb Neuroembryological Collection).

Unit on Neural Circuits and Adaptive Behaviors, National Institute of Mental Health, National Institutes of Health, Bethesda, MD, 20892, USA.

Perinatal neurodevelopment involves extensive formation of neural connections and onset of activity-dependent gene expression for synaptic function and plasticity. Exposure to psychostimulants at this stage imposes significant risks for developing cognitive and affective disorders later in life. However, how developmental exposure to psychostimulants may induce long lasting molecular changes relevant to neural circuit function remains incompletely understood. Read More

From Linear to Nonlinear Responses of Thermal Pure Quantum States.

Phys Rev Lett 2018 Nov;121(22):220601

Department of Basic Science, The University of Tokyo, 3-8-1 Komaba, Meguro, Tokyo 153-8902, Japan.

We propose a self-validating scheme to calculate the unbiased responses of quantum many-body systems to external fields of arbitrary strength at any temperature. By switching on a specified field to a thermal pure quantum state of an isolated system, and tracking its time evolution, one can observe an intrinsic thermalization process driven solely by many-body effects. The transient behavior before thermalization contains rich information on excited states, giving the linear and nonlinear response functions at all frequencies. Read More

State-Resolved Probing of Attosecond Timescale Molecular Dipoles.

J Phys Chem Lett 2018 Dec 14. Epub 2018 Dec 14.

We report an experimental study of iodomethane attosecond transient absorption spectroscopy (ATAS) in the region of iodine 4d core-to-valence/Rydberg excitation. Similar to previous atomic experiments, XUV-NIR delay-dependent absorbance changes reflect a light-induced phase due to an NIR-field driven AC Stark shift of the excited states, as well as pathway interferences arising from couplings between neighboring states. As a novel aspect of molecular ATAS, we observe pronounced differences between the ATAS signatures of valence and Rydberg states. Read More

Kinetics of Ligand-Protein Dissociation from All-Atom Simulations: Are We There Yet?

Biochemistry 2018 Dec 14. Epub 2018 Dec 14.

Large parallel gains in the development of both computational resources as well as sampling methods have now made it possible to simulate dissociation events in ligand-protein complexes with all--atom resolution. Such encouraging progress, together with the inherent spatiotemporal resolution associated with molecular simulations, has left their use for investigating dissociation processes brimming with potential, both in rational drug design, where it can be an invaluable tool for determining the mechanistic driving forces behind dissociation rate constants, as well as in force-field development, where it can provide a catalog of transient molecular structures on which to refine force-fields. Although much progress has been made in making force-fields more accurate, reducing their error for transient structures along a transition path could yet prove to be a critical development helping to make kinetic predictions much more accurate.

Structure and dynamical behavior of non-normal networks.

Sci Adv 2018 Dec 12;4(12):eaau9403. Epub 2018 Dec 12.

Department of Mathematics and naXys, Namur Institute for Complex Systems, University of Namur, rempart de la Vierge 8, B 5000 Namur, Belgium.

We analyze a collection of empirical networks in a wide spectrum of disciplines and show that strong non-normality is ubiquitous in network science. Dynamical processes evolving on non-normal networks exhibit a peculiar behavior, as initial small disturbances may undergo a transient phase and be strongly amplified in linearly stable systems. In addition, eigenvalues may become extremely sensible to noise and have a diminished physical meaning. Read More

Ultrathin-Film Titania Photocatalyst on Nanocavity for CO Reduction with Boosted Catalytic Efficiencies.

Global Chall 2018 Nov 19;2(11):1800032. Epub 2018 Sep 19.

Department of Chemical and Biomolecular Engineering University of Maryland College Park MD 20742 USA.

Photocatalytic CO reduction with water to hydrocarbons represents a viable and sustainable process toward greenhouse gas reduction and fuel/chemical production. Development of more efficient catalysts is the key to mitigate the limits in photocatalytic processes. Here, a novel ultrathin-film photocatalytic light absorber (UFPLA) with TiO films to design efficient photocatalytic CO conversion processes is created. Read More

Anaerobic Degradation of the Plant Sugar Sulfoquinovose Concomitant With HS Production: K-12 and sp. Strain DF1 as Co-culture Model.

Front Microbiol 2018 27;9:2792. Epub 2018 Nov 27.

Department of Biology, University of Konstanz, Konstanz, Germany.

Sulfoquinovose (SQ, 6-deoxy-6-sulfoglucose) is produced by plants and other phototrophs and its biodegradation is a relevant component of the biogeochemical carbon and sulfur cycles. SQ is known to be degraded by aerobic bacterial consortia in two tiers via C-organosulfonates as transient intermediates to CO, water and sulfate. In this study, we present a first laboratory model for anaerobic degradation of SQ by bacterial consortia in two tiers to acetate and hydrogen sulfide (HS). Read More

β-Arrestin Based Receptor Signaling Paradigms: Potential Therapeutic Targets for Complex Age-Related Disorders.

Front Pharmacol 2018 28;9:1369. Epub 2018 Nov 28.

Department of Biomedical Sciences, University of Antwerp, Antwerp, Belgium.

G protein coupled receptors (GPCRs) were first characterized as signal transducers that elicit downstream effects through modulation of guanine (G) nucleotide-binding proteins. The pharmacotherapeutic exploitation of this signaling paradigm has created a drug-based field covering nearly 50% of the current pharmacopeia. Since the groundbreaking discoveries of the late 1990s to the present day, it is now clear however that GPCRs can also generate productive signaling cascades through the modulation of β-arrestin functionality.

Fully bioresorbable vascular scaffolds: lessons learned and future directions.

Nat Rev Cardiol 2018 Dec 13. Epub 2018 Dec 13.

CVPath Institute, Gaithersburg, MD, USA.

Fully bioresorbable scaffolds (BRS) were designed to overcome the limitations of metallic drug-eluting stents, which permanently cage the vessel wall, thereby preventing normal coronary vasomotion, preclude bypass grafting and can provoke long-term foreign-body responses. Although multiple scaffolds have been or are in development, the Absorb Bioresorbable Vascular Scaffold (BVS; Abbott Vascular) was the first FDA-approved device and was widely expected to fulfil the dream of interventional cardiologists of a transient scaffold that would disappear 'when the job was done' and would not hamper further treatment options. Although early, small studies and even large, randomized trials showed beneficial outcomes up to 1 year of follow-up, longer-term results have been disappointing, with increased rates of device thrombosis and target-lesion revascularization.
