Calreticulin regulates syncytialization through control of the synthesis and transportation of E-cadherin in BeWo cells.

Endocrinology 2018 Dec 14. Epub 2018 Dec 14.

Department of Obstetrics and Gynecology, Wakayama Medical University.

During placental development, mononuclear cytotrophoblasts differentiate and fuse to syncytiotrophoblasts (STB) to form syncytia, which secrete human chorionic gonadotropin (hCG). Decreased maternal perfusion of the placenta, which leads to placental dysfunction, induces changes in trophoblast syncytialization. Our previous study showed that calreticulin (CRT), a Ca2+-binding molecular chaperone found in the endoplasmic reticulum, is expressed in the human placenta and is involved in regulating extravillous trophoblast invasion, although its role in villous trophoblasts remains unclear.

When "thirsty" means "less able to activate the signalling wave trigged by a pulse of ozone": A case of study in two Mediterranean deciduous oak species with different drought sensitivity.

Sci Total Environ 2018 Dec 4;657:379-390. Epub 2018 Dec 4.

Department of Agriculture, Food and Environment, University of Pisa, Via del Borghetto 80, Pisa 56124, Italy; CIRSEC, Centre for Climatic Change Impact, University of Pisa, Via del Borghetto 80, Pisa 56124, Italy.

There is a lack of knowledge about the possibility that plants facing abiotic stressors, such as drought, have an altered perception of a pulse of O and incur in alterations of their signalling network. This poses some concerns as to whether defensive strategy to cope episodic O peaks in healthy plants may fail under stress. In this study, a set of saplings of two Mediterranean deciduous species, Quercus cerris and Q. Read More

Permafrost landslides promote soil CO emission and hinder C accumulation.

Sci Total Environ 2018 Dec 4;657:351-364. Epub 2018 Dec 4.

GFZ German Research Centre for Geosciences, Section Geomicrobiology, Telegrafenberg C-425, 14473 Potsdam, Germany; Institute of Earth and Environmental Sciences, University of Potsdam, 14476 Potsdam, Germany.

Landslides are common in high-latitude forest ecosystems that have developed on permafrost. The most vulnerable areas in the permafrost territories of Siberia occur on the south-facing slopes of northern rivers, where they are observed on about 20% of the total area of river slopes. Landslide disturbances will likely increase with climate change especially due to increasing summer-autumn precipitation. Read More

Organophosphate pesticide trichlorfon induced neurotoxic effects in freshwater silver catfish Rhamdia quelen via disruption of blood-brain barrier: Implications on oxidative status, cell viability and brain neurotransmitters.

Comp Biochem Physiol C Toxicol Pharmacol 2018 Dec 11. Epub 2018 Dec 11.

Department of Physiology and Pharmacology, Universidade Federal de Santa Maria, Santa Maria, RS, Brazil.

The aim of this study was to evaluate whether rupture on blood-brain barrier (BBB) can be a pathway for trichlorfon-induced neurotoxic effects, and to investigate its implications on oxidative status, cell viability and brain neurotransmitters in silver catfish (Rhamdia quelen). The BBB permeability was increased in fish exposed for 24 h to 22 mg/L of trichlorfon compared to the control group, as well as in those exposed to 11 and 22 mg/L of trichlorfon for 48 h. Compared to the control group, brain reactive oxygen species and lipid peroxide levels were higher when exposed to 22 mg/L of trichlorfon and 11 and 22 mg/L of trichlorfon after 24 h and 48 h, respectively, while the antioxidant capacity against peroxyl radical levels was lower.

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.
