Neural stem cells in the adult olfactory bulb core generate mature neurons in vivo.

Stem Cells 2021 May 8. Epub 2021 May 8.

Instituto Cajal-Consejo Superior de Investigaciones Científicas (CSIC), Madrid, Spain.

Although previous studies suggest that neural stem cells (NSCs) exist in the adult olfactory bulb (OB), their location, identity, and capacity to generate mature neurons in vivo has been little explored. Here, we injected enhanced green fluorescent protein (EGFP)-expressing retroviral particles into the OB core of adult mice to label dividing cells and to track the differentiation/maturation of any neurons they might generate. EGFP-labeled cells initially expressed adult NSC markers on days 1 to 3 postinjection (dpi), including Nestin, GLAST, Sox2, Prominin-1, and GFAP. Read More

Synthesis and Functional Characterization of 2-(2,5-Dimethoxyphenyl)--(2-fluorobenzyl)ethanamine (25H-NBF) Positional Isomers.

ACS Chem Neurosci 2021 05 28;12(9):1667-1673. Epub 2021 Apr 28.

Laboratory of Toxicology, Department of Bioanalysis, Faculty of Pharmaceutical Sciences, Ghent University, Campus Heymans, Ottergemsesteenweg 460, B-9000 Ghent, Belgium.

Serotonergic psychedelics, substances exerting their pharmacological action through activation of the serotonin 2A receptor (5-HTR), have continuously comprised a substantial fraction of the over 1000 reported New Psychoactive Substances (NPS) so far. Within this category, -benzyl derived phenethylamines, such as NBOMes and NBFs, have shown to be of particular relevance. As these substances remain incompletely characterized, this study aimed at synthesizing positional isomers of 25H-NBF, with two methoxy groups placed on different positions of the phenyl group of the phenethylamine moiety.

Phenanthrene alters the electrical activity of atrial and ventricular myocytes of a polar fish, the Navaga cod.

Aquat Toxicol 2021 Jun 4;235:105823. Epub 2021 Apr 4.

Faculty of Biology, Medicine and Health, Core Technology Facility, University of Manchester, 46 Grafton Street, Manchester M13 9NT, UK. Electronic address:

Oil and gas exploration in the Arctic can result in the release of polycyclic aromatic hydrocarbons (PAHs) into relatively pristine environments. Following the recent spill of approximately 17 500 tonnes of diesel fuel in Norilsk, Russia, May 2020, our study focussed on the effects of phenanthrene, a low molecular weight PAH found in diesel and crude oil, on the isolated atrial and ventricular myocytes from the heart of the polar teleost, the Navaga cod (Eleginus nawaga). Acute exposure to phenanthrene in navaga cardiomyocytes caused significant action potential (AP) prolongation, confirming the proarrhythmic effects of this pollutant. Read More

In situ determination of Cs inventory in soil using a field-portable scintillation gamma spectrometer-dosimeter.

J Environ Radioact 2021 May 2;231:106562. Epub 2021 Mar 2.

Medical Radiation Physics, Department of Translational Medicine, Lund University, Carl Bertil Laurells gata 9, Malmö, Sweden.

A new empirical method for in situ determination of the inventory of Cs in soil (A, kBq m) at grasslands and forests using a field-portable NaI(Tl) scintillation spectrometer-dosimeter was developed. The method is based on evaluation of the ambient dose equivalent build-up factor. The practical implementation of the new method with the spectrometer-dosimeter does not require a priori knowledge of the vertical distribution of Cs in soil. Read More

Optimal control of the COVID-19 pandemic: controlled sanitary deconfinement in Portugal.

Sci Rep 2021 02 10;11(1):3451. Epub 2021 Feb 10.

Departamento de Física Aplicada, Universidade de Santiago de Compostela, 15782, Santiago de Compostela, Spain.

The COVID-19 pandemic has forced policy makers to decree urgent confinements to stop a rapid and massive contagion. However, after that stage, societies are being forced to find an equilibrium between the need to reduce contagion rates and the need to reopen their economies. The experience hitherto lived has provided data on the evolution of the pandemic, in particular the population dynamics as a result of the public health measures enacted. Read More

Driver Liability Assessment in Vehicle Collisions in Spain.

Int J Environ Res Public Health 2021 02 4;18(4). Epub 2021 Feb 4.

Instituto Universitario de Investigación del Automóvil Francisco Aparicio Izquierdo (INSIA-UPM), Escuela Técnica Superior de Ingenieros Industriales (ETSII), Universidad Politécnica de Madrid (UPM), 28006 Madrid, Spain.

An accurate estimation of exposure is essential for road collision rate estimation, which is key when evaluating the impact of road safety measures. The quasi-induced exposure method was developed to estimate relative exposure for different driver groups based on its main hypothesis: the not-at-fault drivers involved in two-vehicle collisions are taken as a random sample of driver populations. Liability assignment is thus crucial in this method to identify not-at-fault drivers, but often no liability labels are given in collision records, so unsupervised analysis tools are required.

Hemodynamics and cardiac autonomic modulation after an acute concurrent exercise circuit in older individuals with pre- to established hypertension.

Clinics (Sao Paulo) 2021 20;76:e1971. Epub 2021 Jan 20.

Programa de Graduacao em Ciencias da Atividade Fisica, Universidade Salgado de Oliveira, Niteroi, RJ, BR.

Objectives: Few studies have investigated whether post-exercise hypotension (PEH) after concurrent exercise (CEX) is related to changes in cardiac output (Q) and systemic vascular resistance (SVR) in older individuals. We tested whether PEH after a single bout of CEX circuits performed in open-access facilities at the Third Age Academies (TAA) in Rio de Janeiro City (Brazil) would be concomitant with decreased Q and SVR in individuals aged ≥60 years with prehypertension. Moreover, we assessed autonomic modulation as a potential mechanism underlying PEH. Read More

Cleaning of oil-polluted bottom sediments of the boreal lake, Samotlor oil field, North Russia: case report.

Water Sci Technol 2020 Dec;82(12):3062-3073

Macquarie Law School, Macquarie University, Sydney, 2109, NSW, Australia.

Small lakes in areas of intensive crude oil production may be susceptible to oil pollution arising from accidental spills and leaks, eventually leading to the pollution of bottom sediments. Effective cleaning of aquatic bottom sediments remains a challenge. Flotation is a potentially simple and reliable approach for the cleanup of bottom sediments without their excavation from the water body. Read More

Comparative proteomics of three Chinese potato cultivars to improve understanding of potato molecular response to late blight disease.

BMC Genomics 2020 Dec 9;21(1):880. Epub 2020 Dec 9.

Southern Potato Research Center of China, Enshi, 445000, Hubei, China.

Background: Late blight disease (LBD) caused by the pathogen Phytophthora infestans (PI), is the most devastating disease limiting potato (Solanum tuberosum) production globally. Currently, this disease pathogen is re-emerging and appearing in new areas at a very high intensity. A better understanding of the natural defense mechanisms against PI in different potato cultivars especially at the protein level is still lacking. Read More

T-piece versus pressure-support ventilation for spontaneous breathing trials before extubation in patients at high risk of reintubation: protocol for a multicentre, randomised controlled trial (TIP-EX).

BMJ Open 2020 11 24;10(11):e042619. Epub 2020 Nov 24.

Service de Médecine Intensive et Réanimation, Centre Hospitalier Departmental La Roche-sur-Yon, La Roche-sur-Yon, Pays de la Loire, France.

Introduction: In intensive care unit (ICU), the decision of extubation is a critical time because mortality is particularly high in case of reintubation. To reduce that risk, guidelines recommend to systematically perform a spontaneous breathing trial (SBT) before extubation in order to mimic the postextubation physiological conditions. SBT is usually performed with a T-piece disconnecting the patient from the ventilator or with low levels of pressure-support ventilation (PSV). Read More

Geoscience and Environment Toulouse (GET), UMR 5563 CNRS University of Toulouse, 14 Avenue Edouard Belin, 31400, Toulouse, France. Electronic address:

The physical and chemical consequences of massive ground ice (wedges) melt upon permafrost thaw is one of the central issues of environmental research linked to climate warming in the Arctic. Little is known about the chemical properties of dispersed ground ice abundant throughout permafrost peatlands that can easily melt with increasing active layer thickness (ALT). This is especially pertinent in continental lowlands, that account for sizeable areas of the Arctic, and contain high amount of organic carbon in both solid (peat) and liquid (porewater) phases.
