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.

During protracted implementation, the character of the connected ecological system will change as a function of external anthropogenic pressures, local metapopulation processes, and environmental fluctuations.

Delivering in-school interventions to improve dietary behaviours amongst 11- to 16-year-olds: A systematic review.

Obes Rev 2018 Dec 14. Epub 2018 Dec 14.

The Staffordshire Centre for Psychological Research and Centre for Health Psychology, Staffordshire University, Stoke-on-Trent, UK.

Childhood obesity is a global health concern, which has both short- and long-term health consequences for the individual, and is a potential burden on health care services and the wider economy. The school environment is a setting where changes can be applied to dietary behaviours, as schools have direct and intensive contact with children. This systematic review evaluated school-based interventions designed to improve dietary behaviours among adolescents (11- to 16-year-olds). Read More

Detection of Malignancy-Associated Phosphoproteome Changes in Human Colorectal Cancer Induced by Cell Surface Binding of Growth-Inhibitory Galectin-4.

IUBMB Life 2018 Dec 14. Epub 2018 Dec 14.

Department of Applied Tumor Biology, Institute of Pathology, Medical School of the Ruprecht-Karls-University, Heidelberg, Germany.

Emerging evidence on efficient tumor growth regulation by endogenous lectins directs interest to determine on a proof-of-principle level the range of information on alterations provided by full-scale analysis using phosphoproteomics. In our pilot study, we tested galectin-4 (gal-4) that is a growth inhibitor for colon cancer cells (CRC), here working with the LS 180 line. In order to cover monitoring of short- and long-term effects stable isotope labeling by amino acids in cell culture-based quantitative phosphoproteomic analyses were conducted on LS 180 cell preparations collected 1 and 72 h after adding gal-4 to the culture medium.

Insufficient compensation for self-motion during perception of object speed: The vestibular Aubert-Fleischl phenomenon.

J Vis 2018 Dec;18(13)

German Center for Vertigo and Balance Disorders (DSGZ), University Hospital of Munich, Ludwig Maximilian University, Munich, Germany.

To estimate object speed with respect to the self, retinal signals must be summed with extraretinal signals that encode the speed of eye and head movement. Prior work has shown that differences in perceptual estimates of object speed based on retinal and oculomotor signals lead to biased percepts such as the Aubert-Fleischl phenomenon (AF), in which moving targets appear slower when pursued. During whole-body movement, additional extraretinal signals, such as those from the vestibular system, may be used to transform object speed estimates from a head-centered to a world-centered reference frame.

Δ9-Tetrahydrocannabinol and Cannabidiol Differentially Regulate Intraocular Pressure.

Invest Ophthalmol Vis Sci 2018 Dec;59(15):5904-5911

The Gill Center for Biomolecular Science and the Department of Psychological and Brain Sciences, Indiana University, Bloomington, Indiana, United States.

Purpose: It has been known for nearly 50 years that cannabis and the psychoactive constituent Δ9-tetrahydrocannabinol (THC) reduce intraocular pressure (IOP). Elevated IOP remains the chief hallmark and therapeutic target for glaucoma, a major cause of blindness. THC likely acts via one of the known cannabinoid-related receptors (CB1, CB2, GPR18, GPR119, GPR55) but this has never been determined explicitly. Read More

Reversing wetland death from 35,000 cuts: Opportunities to restore Louisiana's dredged canals.

PLoS One 2018 14;13(12):e0207717. Epub 2018 Dec 14.

University of Central Florida, Orlando, Florida, United States of America.

We determined the number of permits for oil and gas activities in 14 coastal Louisiana parishes from 1900 to 2017, compared them to land loss on this coast, and estimated their restoration potential. A total of 76,247 oil and gas recovery wells were permitted, of which 35,163 (46%) were on land (as of 2010) and 27,483 of which are officially abandoned. There is a direct spatial and temporal relationship between the number of these permits and land loss, attributable to the above and belowground changes in hydrology resulting from the dredged material levees placed parallel to the canal (spoil banks).

Translating preventive chemotherapy prevalence thresholds for Schistosoma mansoni from the Kato-Katz technique into the point-of-care circulating cathodic antigen diagnostic test.

PLoS Negl Trop Dis 2018 Dec 14;12(12):e0006941. Epub 2018 Dec 14.

Swiss Tropical and Public Health Institute, Basel, Switzerland.

Background: Intervention guidelines against Schistosoma mansoni are based on the Kato-Katz technique. However, Kato-Katz thick smears show low sensitivity, especially for light-intensity infections. The point-of-care circulating cathodic antigen (POC-CCA) is a promising rapid diagnostic test detecting antigen output of living worms in urine and results are reported as trace, 1+, 2+, and 3+.

Phenology of Trichodesmium spp. blooms in the Great Barrier Reef lagoon, Australia, from the ESA-MERIS 10-year mission.

PLoS One 2018 14;13(12):e0208010. Epub 2018 Dec 14.

Commonwealth Scientific and Industrial Research Organization (CSIRO), Canberra, Australia.

Trichodesmium, a filamentous bloom-forming marine cyanobacterium, plays a key role in the biogeochemistry of oligotrophic ocean regions because of the ability to fix nitrogen. Naturally occurring in the Great Barrier Reef (GBR), the contribution of Trichodesmium to the nutrient budget may be of the same order as that entering the system via catchment runoff. However, the cyclicity of Trichodesmium in the GBR is poorly understood and sparsely documented because of the lack of sufficient observations. 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.
