Generation of Fluorescent Versions of Saccharomyces cerevisiae RPA to Study the Conformational Dynamics of Its ssDNA-Binding Domains.

Methods Mol Biol 2021 ;2281:151-168

Department of Biochemistry and Molecular Biology, Saint Louis University School of Medicine, St. Louis, MO, USA.

Replication protein A (RPA) is an essential single-stranded DNA (ssDNA)-binding protein that sequesters ssDNA and protects it from nucleolytic degradation. The RPA-ssDNA nucleoprotein acts as a hub to recruit over two dozen DNA metabolic enzymes onto ssDNA to coordinate DNA replication, repair, and recombination. RPA functions as a heterotrimer composed of RPA70, RPA32, and RPA14 subunits and has multiple DNA-binding and protein-interaction domains. Read More

Alister Spence

Front Psychol 2021 23;12:611536. Epub 2021 Mar 23.

Lecturer in Music, School of Arts and Media, The Faculty of Arts, Design and Architecture, University of New South Wales, Sydney, NSW, Australia.

Among improvisers and composers today there is a resurgence of interest in experimental music (EM) practices that welcome contingency; engaging with unforeseen circumstances as an essential component of the music-making process, and a means to sonic discovery. I propose the (ECIC) as a model with which to better understand these experimental musical works. The historical Experimental Music movement of the 1950s and 60s is briefly revisited, and the jazz tradition included as an essential protagonist; both being important historical movements leading to the formulation of ideas around contingent musical practices.

PIRACY: An Optimized Pipeline for Functional Connectivity Analysis in the Rat Brain.

Front Neurosci 2021 26;15:602170. Epub 2021 Mar 26.

Animal Imaging and Technology, EPFL, Lausanne, Switzerland.

Resting state functional MRI (rs-fMRI) is a widespread and powerful tool for investigating functional connectivity (FC) and brain disorders. However, FC analysis can be seriously affected by random and structured noise from non-neural sources, such as physiology. Thus, it is essential to first reduce thermal noise and then correctly identify and remove non-neural artifacts from rs-fMRI signals through optimized data processing methods. Read More

Bioinformatic pipelines combining denoising and clustering tools allow for more comprehensive prokaryotic and eukaryotic metabarcoding.

Mol Ecol Resour 2021 Apr 9. Epub 2021 Apr 9.

MARBEC, Ifremer, Univ. Montpellier, IRD, CNRS, Sète, France.

Environmental DNA metabarcoding is a powerful tool for studying biodiversity. However, bioinformatic approaches need to adjust to the diversity of taxonomic compartments targeted as well as to each barcode gene specificities. We built and tested a pipeline based on read correction with DADA2 allowing analysing metabarcoding data from prokaryotic (16S) and eukaryotic (18S, COI) life compartments. Read More

Merging NiH Catalysis and Inner-Sphere Metal-Nitrenoid Transfer for Hydroamidation of Alkynes.

J Am Chem Soc 2021 Apr 9. Epub 2021 Apr 9.

Center for Catalytic Hydrocarbon Functionalizations, Institute for Basic Science, Daejeon 34141, South Korea.

The formal hydroamination/hydroamidation utilizing metal hydride is an appealing synthetic tool for the construction of valuable nitrogen-containing compounds from unsaturated hydrocarbons. While significant advances have been made for the functionalizations of alkenes in this realm, the direct hydroamidation of alkynes remains rather limited due to the high feasibility of the key metal-alkenyl intermediate to choose other reaction pathways. Herein, we report a NiH-catalyzed strategy for the hydroamidation of alkynes with dioxazolones, which allows convenient access to synthetically useful secondary enamides in ()--Markovnikov or Markovnikov selectivity.

Applying model approaches in non-model systems: A review and case study on coral cell culture.

PLoS One 2021 8;16(4):e0248953. Epub 2021 Apr 8.

Life Science and Engineering, Virginia Commonwealth University, Richmond, Virginia, United States of America.

Model systems approaches search for commonality in patterns underlying biological diversity and complexity led by common evolutionary paths. The success of the approach does not rest on the species chosen but on the scalability of the model and methods used to develop the model and engage research. Fine-tuning approaches to improve coral cell cultures will provide a robust platform for studying symbiosis breakdown, the calcification mechanism and its disruption, protein interactions, micronutrient transport/exchange, and the toxicity of nanoparticles, among other key biological aspects, with the added advantage of minimizing the ethical conundrum of repeated testing on ecologically threatened organisms.
