Frequent nonrandom shifts in the temporal sequence of developmental landmark events during teleost evolutionary diversification.

Evol Dev 2019 Apr 18:e12288. Epub 2019 Apr 18.

Department of Genetics, SOKENDAI (The Graduate University for Advanced Studies), Mishima, Shizuoka, Japan.

Morphological transformations can be generated by evolutionary changes in the sequence of developmental events. In this study, we examined the evolutionary dynamics of the developmental sequence on a macroevolutionary scale in teleosts. Using the information from previous reports describing the development of 31 species, we extracted the developmental sequences of 19 landmark events involving the formation of phylogenetically conserved body parts; we then inferred ancestral developmental sequences by two different parsimony-based methods-event-pairing and continuous analysis.

Phylogenomics clarifies biogeographic and evolutionary history, and conservation status of West Indian tremblers and thrashers (Aves: Mimidae).

Mol Phylogenet Evol 2019 Apr 15. Epub 2019 Apr 15.

Department of Biology, Boston University, Boston, MA, USA.

The West Indian avifauna has provided fundamental insights into island biogeography, taxon cycles, and the evolution of avian behavior. Our interpretations, however, should rely on robust hypotheses of evolutionary relationships and consistent conclusions about taxonomic status in groups with many endemic island populations. Here we present a phylogenetic study of the West Indian thrashers, tremblers, and allies, an assemblage of at least 5 species found on 29 islands, including what is considered the Lesser Antilles' only avian radiation.

The historical development of pharmacopoeias and the inclusion of exotic herbal drugs with a focus on Europe and Brazil.

J Ethnopharmacol 2019 Apr 15:111891. Epub 2019 Apr 15.

Department of Biomedical Sciences, University of Cagliari, Via Ospedale 72, 09124, Cagliari, Italy. Electronic address:

Ethnopharmacological Relevance: In spite of the rich bio-cultural diversity found in the Neotropics relatively few herbal drugs native to South-America are included in the global pharmacopoeia.

Material And Methods: In the attempt to historically explain the inclusion of herbal drugs into official pharmacopoeias we consider the disparate epidemiology and cultural evolution of the New and the Old World. We then trace the development of pharmacopoeias and review forces that worked towards and against the synchronization of pharmacopoeias and highlight the role of early chemical and pharmacological studies in Europe.

Age, but not severity of injury, mediates decline in executive function: Validation of the rodent touchscreen paradigm for preclinical models of traumatic brain injury.

Behav Brain Res 2019 Apr 15:111912. Epub 2019 Apr 15.

Cognition, Ageing and Neurodegenerative Disease Lab, Adelaide Medical School, The University of Adelaide, Adelaide, SA 5005 Australia. Electronic address:

Increasingly, it is being recognised that traumatic brain injury (TBI) is not just an acute event but instead results in ongoing neuronal injury that may lead to chronic impairments in multiple cognitive domains. Of these, deficits in executive function are one of the more common changes reported following TBI, and are a major predictor of well-being, social function and quality of life in individuals with a history of TBI. In order to fully understand the relationship between TBI and executive dysfunction, including brain mechanisms that may account for this, experimental models are clearly needed. Read More

Amino acid encoding methods for protein sequences: a comprehensive review and assessment.

IEEE/ACM Trans Comput Biol Bioinform 2019 Apr 16. Epub 2019 Apr 16.

As the first step of machine-learning based protein structure and function prediction, the amino acid encoding play a fundamental role in the final success of those methods. Different with the protein sequence encoding, the amino acid encoding can be used in both residue-level and sequence-level prediction of protein properties by combining with different algorithms. However, it does not attract enough attention in the past decades, and there are no comprehensive reviews and assessments about encoding methods so far. Read More

An Improved Method of Total Variation Superiorization Applied to Reconstruction in Proton Computed Tomography.

IEEE Trans Med Imaging 2019 Apr 16. Epub 2019 Apr 16.

Previous work has shown that total variation superiorization (TVS) improves reconstructed image quality in proton computed tomography (pCT). The structure of the TVS algorithm has evolved since then and this work investigated if this new algorithmic structure provides additional benefits to pCT image quality. Structural and parametric changes introduced to the original TVS algorithm included: (1) inclusion or exclusion of TV reduction requirement, (2) a variable number, N, of TV perturbation steps per feasibility-seeking iteration, and (3) introduction of a perturbation kernel 0 < α < 1.

A Covalent Organic Framework Bearing Single Ni Sites as a Synergistic Photocatalyst for Selective Photoreduction of CO2 to CO.

J Am Chem Soc 2019 Apr 18. Epub 2019 Apr 18.

Photocatalytic reduction of CO2 into energy-rich carbon compounds has attracted increasing attention. However, it is still challenge to selectively and effectively convert CO2 to a desirable reaction product. Herein, we report a design of a synergistic photocatalyst for selective reduction of CO2 to CO by using a covalent organic framework bearing single Ni sites (Ni-TpBpy), in which electrons transfer from photosensitizer to Ni sites for CO production by the activated CO2 reduction under visible-light irradiation.

Interfacial Coordinational Coupled Defect Engineering Boosted Portable Zinc-Air Battery with Broad Work Temperature.

Angew Chem Int Ed Engl 2019 Apr 18. Epub 2019 Apr 18.

Lanzhou University, 222 South Tianshui Rd, Lanzhou, CHINA.

Atomic-thick interfacial dominated bifunctional catalyst NiO/CoO transition interfacial nanowires (TINWs) with abundant coordinational defective sites display high electroactivities and durabilities in the oxygen evolution reaction (OER) and the oxygen reduction reaction (ORR). Density functional theory (DFT) calculations unravel that the excellent OER/ORR performance arises from the electron-rich interfacial region coupled with coordinational defective sites, thus endows the fast-redox rate with lower activation barrier for fast electron transfer. When assembled as air-electrode, NiO/CoO TINWs delivered the high specific capacity of 842. Read More

Differentiation of True Nonlinear and Incoherent Mixing of Linear Signals in Action-Detected 2D Spectroscopy.

J Phys Chem A 2019 Apr 18. Epub 2019 Apr 18.

Phase-modulation and phase-cycling schemes have been commonly used in electronic two-dimensional (2D) spectroscopy where the observables are incoherent signals such as fluorescence or photo-current. Although the methods have distinct advantages compared to the coherent signal detected 2D spectroscopy in sensitivity, possibility to measure spectra from isolated quantum systems and direct visualization of the contributions from the different states that contribute to the action signals, ambiguities in interpreting the spectra have emerged. Recent reports have shown that apart from the nonlinear signals from the four pulse interactions, mixing of the linear signals due to the nonlinear population dynamics, the long measurement time of the action signals can also contribute to the measured 2D spectra.

Surface-confined SnS2@C@rGO as High-performance Anode Materials for Sodium-Ion and Potassium-Ion Batteries.

ChemSusChem 2019 Apr 18. Epub 2019 Apr 18.

Shandong University, SDU&Rice Joint Center for Carbon Nanomaterials; Key Laboratory for Liqiud-Solid Structural Evolution & Processing of Materials; school of materials science and engineering;, Jingshi road 17923, Jinan, CHINA.

Potassium-ion batteries (PIBs) and sodium ion batteries (SIBs), owing to the low cost and abundance of K and Na resources, are emerging as promising alternatives to lithium-ion batteries. However, the large radius of K+ and Na+ leads to sluggish kinetics and relatively large volume variations. Herein, we develop a surface-confined strategy to restrain SnS2 in self-generated hierarchically porous carbon networks with an in-situ reduced rGO shell (SnS2@C@rGO). Read More

Cross-peaks in simple 2D NMR experiments from chemical exchange of transverse magnetization.

Angew Chem Int Ed Engl 2019 Apr 18. Epub 2019 Apr 18.

UNITED KINGDOM.

Two-dimensional correlation measurements such as COSY, NOESY, HMQC and HSQC experiments are central to small molecule and biomolecular NMR spectroscopy, and commonly form the basis of more complex experiments designed to study chemical exchange occurring during additional mixing periods. However, exchange occurring during chemical shift evolution periods can also influence the appearance of such spectra. While this is often exploited through one-dimensional lineshape analysis ('dynamic NMR'), the analysis of exchange across multiple chemical shift evolution periods has received less attention.

Insights into Heteroatom-Doped Graphene for Catalytic Ozonation: Active Centers, Reactive Oxygen Species Evolution, and Catalytic Mechanism.

Environ Sci Technol 2019 Apr 18. Epub 2019 Apr 18.

To guide the design of novel graphene-based catalysts in catalytic ozonation for micro-pollutant degradation, the mechanism of catalytic ozonation with heteroatom-doped graphene was clarified. Reduced graphene oxide doped with nitrogen, phosphorus, boron, and sulfur atoms (N-, P-, B-, and S-rGO) were synthesized and their catalytic ozonation performances were evaluated in the degradation of refractory organics and bromate elimination simultaneously. Doping with heteroatoms, except sulfur, significantly improved the catalytic ozonation activity of graphene. Read More

Can Cyanuric Acid and 2,4,6-Triaminopyrimidine Containing Ribonucleosides be Components of Prebiotic RNA? Insights from QM Calculations and MD Simulations.

Chemphyschem 2019 Apr 17. Epub 2019 Apr 17.

University of Lethbridge, Department of Chemistry and Biochemistry, 4401 University Drive West, T1K 3M4, Lethbridge, CANADA.

As a step toward assessing their fitness as pre-RNA nucleobases, we employ DFT and MD simulations to analyze the noncovalent interactions of cyanuric acid (CA) and 2,4,6-triaminopyrimidine (TAP), and the structural properties of the associated ribonucleosides (rNs) and oligonucleotides. Our calculations reveal that the TAP:CA pair has a comparable hydrogen-bond strength to the canonical A:U pair. This strengthens the candidature of CA and TAP as prebiotic nucleobases. Read More

We build on previous observations that Hill-Robertson interference generates an advantage of sex that, in structured populations, can be large enough to explain the evolutionary maintenance of costly sex. We employed a gene network model that explicitly incorporates interactions between genes. Mutations in the gene networks have variable effects that depend on the genetic background in which they appear. Read More

'Why genes in pieces?'-revisited.

Nucleic Acids Res 2019 Apr 18. Epub 2019 Apr 18.

Department of Computer Science, University of Bristol, Bristol BS8 1UB, UK.

The alignment between the boundaries of protein domains and the boundaries of exons could provide evidence for the evolution of proteins via domain shuffling, but literature in the field has so far struggled to conclusively show this. Here, on larger data sets than previously possible, we do finally show that this phenomenon is indisputably found widely across the eukaryotic tree. In contrast, the alignment between exons and the boundaries of intrinsically disordered regions of proteins is not a general property of eukaryotes. Read More

Metabolic acclimation - a key to enhancing photosynthesis in changing environments?

J Exp Bot 2019 Apr 5. Epub 2019 Apr 5.

School of Earth and Environmental Sciences, Faculty of Science and Engineering, University of Manchester, UK.

Plants adjust their photosynthetic capacity in response to their environment in a way that optimises their yield and fitness. There is growing evidence that this acclimation is a response to changes in the leaf metabolome, but the extent to which these are linked and how this is optimized remains poorly understood. Using as an example the metabolic perturbations occurring in response to cold, we define the different stages required for acclimation, discuss the evidence for a metabolic temperature sensor, and suggest further work towards designing climate-smart crops.

Leibniz Institute for Zoo and Wildlife Research, Department of Ecological Dynamics, Alfred-Kowalke-Str. 17, 10315 Berlin, Germany.

Background: The use of environmental DNA for species detection via metabarcoding is growing rapidly. We present a co-designed lab workflow and bioinformatic pipeline to mitigate the 2 most important risks of environmental DNA use: sample contamination and taxonomic misassignment. These risks arise from the need for polymerase chain reaction (PCR) amplification to detect the trace amounts of DNA combined with the necessity of using short target regions due to DNA degradation.

Molecular machinery providing copper bioavailability for spermatozoa along the epididymial tubule in mouse.

Biol Reprod 2019 Feb 19. Epub 2019 Feb 19.

Department of Genetics and Evolution, Institute of Zoology and Biomedical Research, Jagiellonian University, Kraków, Poland.

Progressive functional maturation of spermatozoa is completed during the transit of these cells through the epididymis, a tubule structure connecting a testicle to a vas deferens. Epididymal epithelial cells by means of their secretory and absorptive functions determine a highly specialized luminal microenvironment containing multiple organic and inorganic components. The latter include copper ions, which due to their redox properties are indispensable for critical homeostatic processes occurring in spermatozoa floating in different part of epididymis but can be potentially toxic.

Department of Biological Sciences, Birla Institute of Technology and Science, Pilani, Pilani, Rajasthan 333031 India.

DNA repair is one of the key cellular events which balances between evolvability and integrity of the genome. Endonuclease IV enzymes are class II AP endonucleases under base excision repair pathway which act on abasic site and break the phosphodiester bond at the 5' side. The role and activity of endonuclease IV proteins vary among different organisms; even it is absent in higher eukaryotes. Read More

Adaptive and degenerative evolution of the family in .

PeerJ 2019 12;7:e6740. Epub 2019 Apr 12.

Department of Environmental and Plant Biology and Interdisciplinary Program in Molecular and Cellular Biology, Ohio University, Athens, OH, USA.

Genome sequencing has uncovered tremendous sequence variation within and between species. In plants, in addition to large variations in genome size, a great deal of sequence polymorphism is also evident in several large multi-gene families, including those involved in the ubiquitin-26S proteasome protein degradation system. However, the biological function of this sequence variation is yet not clear. Read More

International Centre of Future Science, Jilin University, Changchun, Jilin, China.

The fossil record of caseids, a clade of faunivorous to large herbivorous Permian synapsids, is unusual in having a poorly documented history. Although Kungurian caseids are common in the well-known continental deposits of North America, and the fossil record of the group extends into the middle Permian (Guadalupian), with the presence of the large caseid in the Mezen Basin faunal assemblage, only two other occurrences are known in older Permian age sediments. One is an undescribed caseid from the Bromacker Quarry in Germany, and the second is from the lower Permian of Richards Spur, Oklahoma. Read More

The discovery of three new hare lagoviruses reveals unexplored viral diversity in this genus.

Virus Evol 2019 Jan 9;5(1):vez005. Epub 2019 Apr 9.

Our knowledge of mammalian viruses has been strongly skewed toward those that cause disease in humans and animals. However, recent metagenomic studies indicate that most apparently healthy organisms carry viruses, and that these seemingly benign viruses may comprise the bulk of virus diversity. The bias toward studying viruses associated with overt disease is apparent in the lagoviruses (family that infect rabbits and hares: although most attention has been directed toward the highly pathogenic members of this genus-rabbit haemorrhagic disease virus and European brown hare syndrome virus-a number of benign lagoviruses have also been identified.

Efficient control of nucleation is a prerequisite for the solution-phase synthesis of nanocrystals. Although the thermodynamics and kinetics of the formation of metal nanoparticles have been largely investigated, fully suppressing the nucleation in solution synthesis remains a major challenge due to the high surface free energy of isolated atoms. In this article, we largely decreased the reaction temperature for ultraviolet (UV) photochemical reduction of HPtCl solution to -60 °C and demonstrated such a method as a fast and convenient process for the synthesis of atomically dispersed Pt.

Single-atom catalysts (SACs) have shown great potential in a wide variety of chemical reactions and become the most active new frontier in catalysis due to the maximum efficiency of metal atom use. The key obstacle in preparing SAs lies in the development of appropriate supports that can avoid aggregation or sintering during synthetic procedures. As such, achieving high loadings of isolated SAs is nontrivial and challenging. Read More

An essential descriptor for the oxygen evolution reaction on reducible metal oxide surfaces.

Chem Sci 2019 Mar 1;10(11):3340-3345. Epub 2019 Feb 1.

Department of Physics , Southern University of Science and Technology , Shenzhen 518055 , China . Email:

The development of a universal activity descriptor like the d-band model for transition metal catalysts is of great importance to catalyst design. However, due to the complicated electronic structures of metal oxides, the correlation of the binding energies of reaction intermediates (*OH, *O, and *OOH) in the oxygen evolution reaction (OER) with experimentally controllable properties of metal oxides has not been well established. Here we demonstrate that excess electrons are the essential factor that governs the binding properties of intermediates on the surfaces of reducible metal oxides. Read More

Proof-of-Concept Multistage Biomimetic Liposomal DNA Origami Nanosystem for the Remote Loading of Doxorubicin.

ACS Med Chem Lett 2019 Apr 31;10(4):517-521. Epub 2019 Jan 31.

Clinical and Experimental Pharmacology Unit, IRCCS CRO Aviano-National Cancer Institute, 33081 Aviano, Italy.

One of the most promising applications of DNA origami is its use as an excellent evolution of nanostructured intelligent systems for drug delivery, but short lifetime and immune-activation are still major challenges to overcome. On the contrary, stealth liposomes have long-circulation time and are well tolerated by the immune system. To overcome DNA origami limitations, we have designed and synthesized a compact short tube DNA origami (STDO) of approximately 30 nm in length and 10 nm in width. Read More

Neurocranial development of the coelacanth and the evolution of the sarcopterygian head.

Nature 2019 Apr 17. Epub 2019 Apr 17.

UMR 7179 (MNHN-CNRS) MECADEV, Département Adaptations du Vivant, Muséum National d'Histoire Naturelle, Paris, France.

The neurocranium of sarcopterygian fishes was originally divided into an anterior (ethmosphenoid) and posterior (otoccipital) portion by an intracranial joint, and underwent major changes in its overall geometry before fusing into a single unit in lungfishes and early tetrapods. Although the pattern of these changes is well-documented, the developmental mechanisms that underpin variation in the form of the neurocranium and its associated soft tissues during the evolution of sarcopterygian fishes remain poorly understood. The coelacanth Latimeria is the only known living vertebrate that retains an intracranial joint. Read More
