Advancing human health risk assessment.

EFSA J 2019 Jul 8;17(Suppl 1):e170712. Epub 2019 Jul 8.

Formerly World Health Organisation Geneva CH.

The current/traditional human health risk assessment paradigm is challenged by recent scientific and technical advances, and ethical demands. The current approach is considered too resource intensive, is not always reliable, can raise issues of reproducibility, is mostly animal based and does not necessarily provide an understanding of the underlying mechanisms of toxicity. From an ethical and scientific viewpoint, a paradigm shift is required to deliver testing strategies that enable reliable, animal-free hazard and risk assessments, which are based on a mechanistic understanding of chemical toxicity and make use of exposure science and epidemiological data.

Optimization of flow cytometry parameters for high-throughput screening of spores of the filamentous fungus Trichoderma reesei.

J Biotechnol 2020 Jun 30. Epub 2020 Jun 30.

Université Paris-Saclay, INRAE, AgroParisTech, UMR SayFood, 78850 Thivernal-Grignon, France.

Flow cytometry (FCM) is a powerful technique still little used to study filamentous fungi due to physical constraints: the hyphae are too large to enter the FCM fluidic system, unless spores can be analyzed at a very early stage of germination. The technique nevertheless has strong potential for the study of these micro-organisms (spore sorting, viability, characterization etc.). Read More

A critical assessment of marine predator isoscapes within the southern Indian Ocean.

Mov Ecol 2020 29;8:29. Epub 2020 Jun 29.

Marine Apex Predator Research Unit (MAPRU), Department of Zoology, Institute for Coastal and Marine Research, Nelson Mandela University, Port Elizabeth, South Africa.

Background: Precise and accurate retrospective geolocation of marine predators via their tissues' isotopic composition relies on quality reference maps of relevant isotopic gradients ("isoscapes"). Additionally, a good working knowledge of any discrimination factors that may offset a marine predator's isotopic composition from baseline isotopic values, as well as tissue specific retention rates, are imperative. We provide a critical assessment of inter-specific differences among marine predator-level isoscapes within the Indian Sector of the Southern Ocean. Read More

Physiological blood-brain transport is impaired with age by a shift in transcytosis.

Nature 2020 Jul 1. Epub 2020 Jul 1.

ChEM-H, Stanford University, Stanford, CA, USA.

The vascular interface of the brain, known as the blood-brain barrier (BBB), is understood to maintain brain function in part via its low transcellular permeability. Yet, recent studies have demonstrated that brain ageing is sensitive to circulatory proteins. Thus, it is unclear whether permeability to individually injected exogenous tracers-as is standard in BBB studies-fully represents blood-to-brain transport. Read More

Lipid Compositions in Infant Formulas Affect the Solubilization of Antimalarial Drugs Artefenomel (OZ439) and Ferroquine during Digestion.

Mol Pharm 2020 Jul 23;17(7):2749-2759. Epub 2020 Jun 23.

Drug Delivery, Disposition and Dynamics, Monash Institute of Pharmaceutical Sciences, Monash University, 381 Royal Parade, Parkville, Victoria 3052, Australia.

Recent studies have shown that the solubilization of two antimalarial drug candidates, artefenomel (OZ439) and ferroquine (FQ), designed to provide a single-dose combination therapy for uncomplicated malaria can be enhanced using milk as a lipid-based formulation. However, milk as an excipient faces significant quality and regulatory hurdles. We therefore have investigated infant formula as a potential alternative formulation approach. Read More

A prebiotic-enhanced lipid-based nutrient supplement (LNSp) increases Bifidobacterium relative abundance and enhances short-chain fatty acid production in simulated colonic microbiota from undernourished infants.

FEMS Microbiol Ecol 2020 Jul;96(7)

Center for Microbial Ecology and Technology, Ghent University, Coupure links 653, 9000 Ghent, Belgium.

Undernutrition remains a public health problem in the developing world with an attributable under-five death proportion of 45%. Lower gut microbiota diversity and poor metabolic output are associated with undernutrition and new therapeutic paths may come from steering gut microbiota composition and functionality. Using a dynamic gut model, the Simulator of Human Intestinal Microbial Ecosystem (SHIME®), we investigated the effect of a lipid-based nutrient supplement enriched with prebiotics (LNSp), compared to LNS alone and control treatment, on the composition and metabolic functionality of fecal microbiota from three infants suffering from undernutrition.

Linkage disequilibrium vs. pedigree: Genomic selection prediction accuracy in conifer species.

PLoS One 2020 10;15(6):e0232201. Epub 2020 Jun 10.

Department of Forest and Conservation Sciences, Faculty of Forestry, The University of British Columbia, Vancouver, British Columbia, Canada.

Background: The presupposition of genomic selection (GS) is that predictive accuracies should be based on population-wide linkage disequilibrium (LD). However, in species with large, highly complex genomes the limitation of marker density may preclude the ability to resolve LD accurately enough for GS. Here we investigate such an effect in two conifer species with ~ 20 Gbp genomes, Douglas-fir (Pseudotsuga menziesii Mirb. Read More

Surgical anatomy of the pectoralis major tendon insertion revisited: relationship to nearby structures and the pectoral eminence for defining the anatomic footprint.

JSES Int 2020 Jun 7;4(2):324-332. Epub 2020 May 7.

Section of Orthopaedic Surgery, Department of Surgery, Cumming School of Medicine, University of Calgary, Calgary, AB, Canada.

Background: Intraoperative identification of the normal pectoralis major (PM) footprint can be challenging to identify in the acute and chronic settings. The purpose of this study was to revisit the anatomic footprint of the PM tendon and to determine which nearby landmarks can be used to re-create the normal insertion site during anatomic repair or reconstruction.

Methods: Twenty-one fresh-frozen human cadaveric shoulder specimens were used to define the PM tendon width (ie, superior-to-inferior) and to determine the relationship between the superior aspect of the PM insertion and that of the latissimus dorsi (LD) and anterior deltoid (AD) tendons.

A generic PBTK model implemented in the MCRA platform: Predictive performance and uses in risk assessment of chemicals.

Food Chem Toxicol 2020 May 27;142:111440. Epub 2020 May 27.

INERIS, Unit Models for Ecotoxicology and Toxicology (METO), Verneuil-en-Halatte, France.

Physiologically-based toxicokinetic (PBTK) models are important tools for in vitro to in vivo or inter-species extrapolations in health risk assessment of foodborne and non-foodborne chemicals. Here we present a generic PBTK model implemented in the EuroMix toolbox, MCRA 9 and predict internal kinetics of nine chemicals (three endocrine disrupters, three liver steatosis inducers, and three developmental toxicants), in data-rich and data-poor conditions, when increasingly complex levels of parametrization are applied. At the first stage, only QSAR models were used to determine substance-specific parameters, then some parameter values were refined by estimates from substance-specific or high-throughput in vitro experiments.

Universal metabolic constraints shape the evolutionary ecology of diving in animals.

Proc Biol Sci 2020 May 27;287(1927):20200488. Epub 2020 May 27.

Marine Biology and Ecology Research Centre, School of Biological and Marine Sciences, University of Plymouth, Drake Circus, Plymouth PL4 8AA, UK.

Diving as a lifestyle has evolved on multiple occasions when air-breathing terrestrial animals invaded the aquatic realm, and diving performance shapes the ecology and behaviour of all air-breathing aquatic taxa, from small insects to great whales. Using the largest dataset yet assembled, we show that maximum dive duration increases predictably with body mass in both ectotherms and endotherms. Compared to endotherms, ectotherms can remain submerged for longer, but the mass scaling relationship for dive duration is much steeper in endotherms than in ectotherms. Read More

Ventricular septal defect jeopardizes the autograft in a Ross operation.

Ann Thorac Surg 2020 May 20. Epub 2020 May 20.

Department of Cardiac Surgery, Lens Hospital, Lens, France; Bois Bernard Private Hospital, Ramsay Générale de Santé, Bois Bernard, France.

The Ross operation is the gold standard for aortic valve replacement (AVR) in young patients as it is a durable and anticoagulation-free alternative to mechanical AVR. Careful assessment of the pulmonary valve is critical as it should become a durable neoaortic valve. Here we report the case of a patient in whom the pulmonary autograft was jeopardized by a large doubly committed ventricular septal defect (VSD), which did not offer sufficient autologous tissue for the proximal suture line.

Nanocellulose: From Fundamentals to Advanced Applications.

Front Chem 2020 6;8:392. Epub 2020 May 6.

Materials Technology Research Group, School of Chemical Sciences, Universiti Sains Malaysia, Penang, Malaysia.

Over the past few years, nanocellulose (NC), cellulose in the form of nanostructures, has been proved to be one of the most prominent green materials of modern times. NC materials have gained growing interests owing to their attractive and excellent characteristics such as abundance, high aspect ratio, better mechanical properties, renewability, and biocompatibility. The abundant hydroxyl functional groups allow a wide range of functionalizations chemical reactions, leading to developing various materials with tunable features. Read More

Antarctic petrels 'on the ice rocks': wintering strategy of an Antarctic seabird.

R Soc Open Sci 2020 Apr 1;7(4):191429. Epub 2020 Apr 1.

Norwegian Polar Institute, Fram Centre, 9296 Tromsø, Norway.

There is a paucity of information on the foraging ecology, especially individual use of sea-ice features and icebergs, over the non-breeding season in many seabird species. Using geolocators and stable isotopes, we defined the movements, distribution and diet of adult Antarctic petrels from the largest known breeding colony, the inland Svarthamaren, Antarctica. More specifically, we examined how sea-ice concentration and free-drifting icebergs affect the distribution of Antarctic petrels. Read More

Geochemical characterization of uranium mill tailings (Bois Noirs Limouzat, France) highlighting the U and Ra retention.

J Environ Radioact 2020 Jul 30;218:106251. Epub 2020 Mar 30.

ORANO Mining, 125 Avenue de Paris, 92320, Châtillon, France. Electronic address:

As with other metals, the management of tailings from former uranium (U) mines requires a good knowledge of the geochemical mechanisms governing the retention of radioelements of interest: U and Ra. This article presents the results of the study of the bearing phases featuring these two radioelements within the Bois Noirs Limouzat tailings storage facility (Loire), the only site in France where the tailings (a sandy silt facies and a clayey silt facies) are currently stored only under water. The aim is to gain a better understanding of their respective mobility under current storage conditions. Read More

Electrochemical Ruthenium-Catalyzed C-H Hydroxylation of Amine Derivatives in Aqueous Acid.

Org Lett 2020 May 18. Epub 2020 May 18.

Department of Chemistry, University of Utah, 315 South 1400 East, Salt Lake City, Utah 84112, United States.

The development of an electrochemically driven, ruthenium-catalyzed C-H hydroxylation reaction of amine-derived substrates bearing tertiary C-H bonds is described. The reaction is performed under constant current electrolysis in a divided cell to afford alcohol products in yields comparable to those of our previously reported process, which requires the use of stoichiometric HIO for catalytic turnover. With aqueous acid as solvent, the cathodic electrode reaction simply involves the reduction of protons to evolve hydrogen gas. Read More
