MCmatlab: an open-source, user-friendly, MATLAB-integrated three-dimensional Monte Carlo light transport solver with heat diffusion and tissue damage.

J Biomed Opt 2018 Dec;23(12):1-6

Technical University of Denmark, Department of Photonics Engineering, Roskilde, Denmark.

While there exist many Monte Carlo (MC) programs for solving the radiative transfer equation (RTE) in biological tissues, we have identified a need for an open-source MC program that is sufficiently user-friendly for use in an education environment, in which detailed knowledge of compiling or UNIX command-line cannot be assumed. Therefore, we introduce MCmatlab, an open-source codebase thus far consisting of (a) a fast three-dimensional MC RTE solver and (b) a finite-element heat diffusion and Arrhenius-based thermal tissue damage simulator, both run in MATLAB. The kernel for both of these solvers is written in parallelized C and implemented as MATLAB MEX functions, combining the speed of C with the familiarity and versatility of MATLAB. Read More

Mol Ecol Resour 2018 Dec 16. Epub 2018 Dec 16.

Museum of Southwestern Biology and Department of Biology, MSC03 2020, 1 University of New Mexico, Albuquerque, New Mexico, 87131-0001, USA.

Avian malaria and related haemosporidians (Plasmodium, [Para]Haemoproteus, and Leucocytoozoon) represent an exciting multi-host, multi-parasite system in ecology and evolution. Global research in this field accelerated after 1) the publication in 2000 of PCR protocols to sequence a haemosporidian mitochondrial (mtDNA) barcode, and 2) the development in 2009 of an open-access database to document the geographic and host ranges of parasite mtDNA haplotypes. Isolating haemosporidian nuclear DNA from bird hosts, however, has been technically challenging, slowing the transition to genomic-scale sequencing techniques. Read More

Arousal from hibernation and reactivation of Eptesicus fuscus gammaherpesvirus (EfHV) in big brown bats.

Transbound Emerg Dis 2018 Dec 16. Epub 2018 Dec 16.

Department of Microbiology, Western College of Veterinary Microbiology, University of Saskatchewan, Saskatoon, Saskatchewan, Canada.

Many viruses that cause serious and often fatal disease in humans have spilled over from bats. Recent evidence suggests that stress may enhance virus shedding by bats increasing the possibility of transmission to other species. To understand the reasons for spillover it is therefore important to determine the molecular pathways that link stress to virus reactivation and shedding in bats. Read More

Soil organic carbon stability in forests: distinct effects of tree species identity and traits.

Glob Chang Biol 2018 Dec 16. Epub 2018 Dec 16.

Chair of Soil Science, Technical University Munich (TUM), Emil-Ramann-Str. 2, D-85354, Freising, Germany.

Rising atmospheric CO concentrations have increased interest in the potential for forest ecosystems and soils to act as carbon (C) sinks. While soil organic C contents often vary with tree species identity, little is known about if, and how, tree species influence the stability of C in soil. Using a 40-year-old common garden experiment with replicated plots of eleven temperate tree species, we investigated relationships between soil organic matter (SOM) stability in mineral soils and 17 ecological factors (including tree tissue chemistry, magnitude of organic matter inputs and their turnover, microbial community descriptors, and soil physico-chemical properties).

100 Years of phenogenetics: Valentin Haecker and his examination of the phenotype.

Mol Genet Genomics 2018 Dec 15. Epub 2018 Dec 15.

Research Group for Biology Education, Faculty of Biological Sciences, Institute of Zoology and Evolutionary Research, Friedrich-Schiller-University Jena, Am Steiger 3, Bienenhaus, 07743, Jena, Germany.

Following the 'rediscovery' of Mendel's work around 1900 the study of genetics grew rapidly and multiple new inheritance theories quickly emerged such as Hugo de Vries' "Mutation Theory" (1901) and the "Boveri-Sutton Chromosome Theory" (1902). Mendel's work also caught the attention of the German geneticist Valentin Haecker, yet he was generally dissatisfied the simplicity of Mendelian genetics as he believed that inheritance and the expression of various characteristics appeared to be much more complex than the proposed "on-off hypotheses". Haecker's primary objection was that Mendelian-based theories still failed to bridge the gap between hereditary units and phenotypic traits. Read More

Comparative analysis of intracellular metabolites, proteins and their molecular functions in a flor yeast strain under two enological conditions.

World J Microbiol Biotechnol 2018 Dec 15;35(1). Epub 2018 Dec 15.

Department of Microbiology, Severo Ochoa (C6) building, Agrifood Campus of International Excellence ceiA3, University of Córdoba, Córdoba, Spain.

Flor yeasts confer a wide range of organoleptic properties to Sherry-type wines during a process called "biological aging" that takes place after alcoholic fermentation. These kinds of yeasts adapt to a biological aging condition by forming a biofilm known as "flor velum" and by changing from fermentative to oxidative metabolism. It has been reported that some functions such as increase of cell surface hydrophobicity or changes to lipid metabolism are enhanced when yeasts switch to biofilm lifestyle. Read More

Adaptation of Rabensburg virus (RBGV) to vertebrate hosts by experimental evolution.

Virology 2018 Dec 13;528:30-36. Epub 2018 Dec 13.

The Arbovirus Laboratory, Wadsworth Center, New York State Department of Health, Slingerlands, NY, USA; Department of Biomedical Sciences, State University of New York at Albany School of Public Health, Albany, NY, USA.

Rabensburg virus (RBGV; Flaviviridae, Flavivirus) has been classified as both a novel flavivirus and a unique lineage of West Nile virus (WNV). RBGV and WNV share approximately 76% sequence homology, yet RBGV does not replicate to high viral titers within vertebrate cell lines at physiological temperatures and has not been naturally isolated from a vertebrate host. These unique genetic and biological characteristics make RBGV a viable tool to identify the genetic determinants of flavivirus infectivity and fitness in vertebrate hosts. Read More
