pSSbond-PseAAC: Prediction of disulfide bonding sites by integration of PseAAC and statistical moments.

J Theor Biol 2018 Dec 11. Epub 2018 Dec 11.

Gordon Life Science Institute, Boston, MA 02478, USA.

The structure of protein gains additional stability against various detrimental effects by the presence of disulfide bonds. The formation of correct disulfide bonds between cysteine residues ensures proper in vivo and in vitro folding of the protein. Many cysteine residues can be present in the polypeptide chain of a protein, however, not all cysteine residues are involved in the formation of a disulfide bond, and therefore, accurate prediction of these bonds is crucial for identifying biophysical characteristics of a protein.

A two-thresholds policy to interrupt transmission of West Nile Virus to birds.

J Theor Biol 2018 Dec 11. Epub 2018 Dec 11.

Department of Mathematics & Statistics, York University, Toronto, ON, M3J 1P3, Canada.

This paper proposes a model of West Nile Virus (WNV) including threshold control policies concerning the culling of mosquitoes and birds under different conditions. Two thresholds are introduced to estimate whether and which control strategy should be implemented. For each mosquito threshold level [Formula: see text] the dynamical behaviour of the proposed non-smooth system is investigated as the bird threshold level [Formula: see text] varies, focusing on the existence of sliding domains, the existence of pseudo-equilibria, real or virtual of the endemic equilibria, global stability of these steady states, and the most interesting case of the occurrence of a novel globally asymptotically stable pseudo-attractor.

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).

In Vivo Photovoltaic Performance of a Silicon Nanowire Photodiode-Based Retinal Prosthesis.

Invest Ophthalmol Vis Sci 2018 Dec;59(15):5885-5892

Jacobs Retina Center at Shiley Eye Institute, Department of Ophthalmology, University of California, San Diego, California, United States.

Purpose: For more than 20 years, there has been an international, multidisciplinary effort to develop retinal prostheses to restore functional vision to patients blinded by retinal degeneration. We developed a novel subretinal prosthesis with 1512 optically addressed silicon nanowire photodiodes, which transduce incident light into an electrical stimulation of the remaining retinal circuitry. This study was conducted to evaluate the efficacy of optically driving the subretinal prosthesis to produce visual cortex activation via electrical stimulation of the retina. Read More

CD71+VISTA+ erythroid cells promote the development and function of regulatory T cells through TGF-β.

PLoS Biol 2018 Dec 14;16(12):e2006649. Epub 2018 Dec 14.

Department of Dentistry, Faculty of Medicine and Dentistry, University of Alberta, Edmonton, Canada.

Cell-surface transferrin receptor (CD71+) erythroid cells are abundant in newborns with immunomodulatory properties. Here, we show that neonatal CD71+ erythroid cells express significant levels of V-domain Immunoglobulin (Ig) Suppressor of T Cell Activation (VISTA) and, via constitutive production of transforming growth factor (TGF)- β, play a pivotal role in promotion of naïve CD4+ T cells into regulatory T cells (Tregs). Interestingly, we discovered that CD71+VISTA+ erythroid cells produce significantly higher levels of TGF-β compared to CD71+VISTA- erythroid cells and CD71+ erythroid cells from the VISTA knock-out (KO) mice.

Asymmetrical interference between number and item size perception provides evidence for a domain specific impairment in dyscalculia.

PLoS One 2018 14;13(12):e0209256. Epub 2018 Dec 14.

Cognitive Neuroimaging Unit, CEA DRF/I2BM, INSERM, Université Paris-Sud, Université Paris-Saclay, NeuroSpin Center, Gif-sur-Yvette, France.

Dyscalculia, a specific learning disability that impacts arithmetical skills, has previously been associated to a deficit in the precision of the system that estimates the approximate number of objects in visual scenes (the so called 'number sense' system). However, because in tasks involving numerosity comparisons dyscalculics' judgements appears disproportionally affected by continuous quantitative dimensions (such as the size of the items), an alternative view linked dyscalculia to a domain-general difficulty in inhibiting task-irrelevant responses. To arbitrate between these views, we evaluated the degree of reciprocal interference between numerical and non-numerical quantitative dimensions in adult dyscalculics and matched controls. Read More
