DNA barcoding of terrestrial invasive plant species in Southwest Michigan.

Because of the detrimental effects of terrestrial invasive plant species (TIPS) on native species, ecosystems, public health, and the economy, many countries have been actively looking for strategies to prevent the introduction and minimize the spread of TIPS. Fast and accurate detection of TIPS is essential to achieving these goals. Conventionally, invasive species monitoring has relied on morphological attributes.

Migratory singers dynamically overlap the signal space of a breeding warbler community.

Migratory species inhabit many communities along their migratory routes. Across taxa, these species repeatedly move into and out of communities, interacting with each other and locally breeding species and competing for resources and niche space. However, their influence is rarely considered in analyses of ecological processes within the communities they temporarily occupy.

Laryngeal symptoms related to motor phenotypes in Parkinson's disease: A systematic review.

Objective: This study aimed to systematically review the associations between motor clinical phenotypes in Parkinson's disease (PD) and laryngeal disease symptoms. Laryngeal dysfunctions such as dysphonia and dysphagia are ubiquitous in people with Parkinson's disease (PwPD). Similar to other disease symptoms, they manifest variably across PwPD.

Molecular dynamics study on the interfacial properties of mixtures of monomers of polyvinylpyrrolidone (PVP)-based battery binders on graphene and graphite surfaces.

This study investigates the behavior of two different mixtures of monomers of polyvinylpyrrolidone (PVP)-based battery binders, polyvinylpyrrolidone:polyvinylidene difluoride (PVP:PVDF) and polyvinylpyrrolidone:polyacrylic acid (PVP:PAA), at graphene and graphite interfaces using classical molecular dynamics simulations. The aim is to identify the best performing monomer binder blend and carbon-based material for the design of battery-optimized energy devices. The PVP:PAA monomer binder blend and graphite are found to have the best interaction energies, densification upon adsorption, and more ordered structure.

Red-winged blackbirds nesting nearer to yellow warbler and conspecific nests experience less brood parasitism.

In functionally referential communication systems, the signaler's message intended for a conspecific receiver may be intercepted and used by a heterospecific eavesdropper for its own benefit. For example, yellow warblers () produce seet calls to warn conspecifics of nearby brood parasitic brown-headed cowbirds (), and red-winged blackbirds () eavesdrop on and recruit to seet calls to mob the brood parasites. Prior work found that warblers nesting closer to blackbirds were less likely to be parasitized, suggesting that blackbirds may even be the target of warbler's seet calls to assist with antiparasitic defense.

Emergency medical services Milestones 2.0: What has changed?

Background: Since 2015, development of competencies by emergency medical services (EMS) fellows have been evaluated using the EMS Milestones 1.0 developed by a working group consisting of relevant stakeholders convened by the Accreditation Council for Graduate Medical Education (ACGME). Feedback from users and data collected from the milestones assessments in the interim indicated a need for revision of the original milestones.

Transition to lanadelumab-flyo from three medications for a hereditary angioedema patient with a variant in the gene: A case report.

Non-SERPING1 gene variant hereditary angioedema patients often need to take progesterone, attenuated androgens, and antifibrinolytics to control symptoms. These drugs may need to be tapered to extinction or reduced as lanadelumab-flyo reaches maximum concentration.

Functional relationships of three NFU proteins in the biogenesis of chloroplastic iron-sulfur clusters.

Iron-sulfur clusters are required in a variety of biological processes. Biogenesis of iron-sulfur clusters includes assembly of iron-sulfur clusters on scaffold complexes and transfer of iron-sulfur clusters to recipient apoproteins by iron-sulfur carriers, such as nitrogen-fixation-subunit-U (NFU)-type proteins. has three plastid-targeted NFUs: NFU1, NFU2, and NFU3.

This pilot study was undertaken to assess the current practices of burn patient decontamination outside of mass casualty events within level I and II trauma center emergency departments in the state of Michigan.

A century of intermittent eco-evolutionary feedbacks resulted in novel trait combinations in invasive Great Lakes alewives ().

Species introductions provide opportunities to quantify rates and patterns of evolutionary change in response to novel environments. Alewives () are native to the East Coast of North America where they ascend coastal rivers to spawn in lakes and then return to the ocean. Some populations have become landlocked within the last 350 years and diverged phenotypically from their ancestral marine population.

A Survey of Small-Scale Waves and Wave-Like Phenomena in Jupiter's Atmosphere Detected by JunoCam.

In the first 20 orbits of the Juno spacecraft around Jupiter, we have identified a variety of wave-like features in images made by its public-outreach camera, JunoCam. Because of Juno's unprecedented and repeated proximity to Jupiter's cloud tops during its close approaches, JunoCam has detected more wave structures than any previous surveys. Most of the waves appear in long wave packets, oriented east-west and populated by narrow wave crests.

Habitat transitions alter the adaptive landscape and shape phenotypic evolution in needlefishes (Belonidae).

Habitat occupancy can have a profound influence on macroevolutionary dynamics, and a switch in major habitat type may alter the evolutionary trajectory of a lineage. In this study, we investigate how evolutionary transitions between marine and freshwater habitats affect macroevolutionary adaptive landscapes, using needlefishes (Belonidae) as a model system. We examined the evolution of body shape and size in marine and freshwater needlefishes and tested for phenotypic change in response to transitions between habitats.

Two organelle RNA recognition motif proteins affect distinct sets of RNA editing sites in the plastid.

Plastid and mitochondrial RNAs in vascular plants are subjected to cytidine-to-uridine editing. The model plant species (Arabidopsis) has two nuclear-encoded plastid-targeted organelle RNA recognition motif (ORRM) proteins: ORRM1 and ORRM6. In the mutant, 21 plastid RNA editing sites were affected but none are essential to photosynthesis.

Synthesis of a novel hexaazatriphenylene derivative for the selective detection of copper ions in aqueous solution.

A hexaazatriphenylene (HAT) derivative, naphtho[2,3-h]naphtho[2',3':7,8]quinoxalino[2,3-]naphtho[2',3':7,8]quinoxalino[2,3-]phenazine-5,10,15,20,25,30-hexaone (NQH) was synthesized, characterized, and found to have novel properties in being selective toward the detection of copper (Cu) ions. The capability of NQH to be employed as a colorimetric, chemo-fluorescence and electrochemical sensor for the detection of Cu was demonstrated by performing UV-Vis absorbance, fluorescence intensity, and cyclic voltammetry (CV) measurements. The interaction between NQH and Cu was initially observed with an obvious color change from yellow to brown upon the addition of Cu ions to NQH.

Comparative analysis of landscape effects on spatial genetic structure of the big brown bat and one of its cimicid ectoparasites.

Identification of landscape features that correlate with genetic structure permits understanding of factors that may influence gene flow in a species. Comparing effects of the landscape on a parasite and host provides potential insights into parasite-host ecology. We compared fine-scale spatial genetic structure between big brown bats () and their cimicid ectoparasite (; class Insecta) in the lower Great Lakes region of the United States, in an area of about 160,000 km.

Temporal regulation of planarian eye regeneration.

While tissue regeneration is typically studied using standard injury models, in nature injuries vary greatly in the amount and location of tissues lost. Planarians have the unique ability to regenerate from many different injuries (including from tiny fragments with no brain), allowing us to study the effects of different injuries on regeneration timelines. We followed the timing of regeneration for one organ, the eye, after multiple injury types that involved tissue loss (single- and double-eye ablation, and decapitation) in .

Identification and Roles of Photosystem II Assembly, Stability, and Repair Factors in Arabidopsis.

Photosystem II (PSII) is a multi-component pigment-protein complex that is responsible for water splitting, oxygen evolution, and plastoquinone reduction. Components of PSII can be classified into core proteins, low-molecular-mass proteins, extrinsic oxygen-evolving complex (OEC) proteins, and light-harvesting complex II proteins. In addition to these PSII subunits, more than 60 auxiliary proteins, enzymes, or components of thylakoid protein trafficking/targeting systems have been discovered to be directly or indirectly involved in de novo assembly and/or the repair and reassembly cycle of PSII.

Factors associated with medication adherence among psychiatric outpatients at substance abuse risk.

Substance misuse is usually associated with poorer psychiatric medication adherence among psychiatric patients. Identifying predictors of medication adherence among patients with dual psychiatric and substance misuse problems is important because poor adherence is associated with relapse and re-hospitalization. The subjects were patients newly admitted to a psychiatric outpatient program who were prescribed psychiatric medication from different providers during the six months prior to admission; all also had substance misuse histories (N=131).

A Non-Orthogonal Block-Localized Effective Hamiltonian Approach for Chemical and Enzymatic Reactions.

The effective Hamiltonian-molecular orbital and valence bond (EH-MOVB) method based on non-orthogonal block-localized fragment orbitals has been implemented into the program CHARMM for molecular dynamics simulations of chemical and enzymatic reactions, making use of semiempirical quantum mechanical models. Building upon ab initio MOVB theory, we make use of two parameters in the EH-MOVB method to fit the barrier height and the relative energy between the reactant and product state for a given chemical reaction to be in agreement with experiment or high-level ab initio or density functional results. Consequently, the EH-MOVB method provides a highly accurate and computationally efficient QM/MM model for dynamics simulation of chemical reactions in solution.
