Cladotanytarsus saetheri, sp. nov., a widely distributed species (Fennoscandia; Russia: Far East; Canada: Manitoba; USA: Colorado, Michigan, South Carolina, Wisconsin) is described and compared with C. gedanicus Giłka, 2001 on the basis of new records (Fennoscandia; Canada: Manitoba, Nunavut; USA: Colorado, New Mexico). Intraspecific morphological variability of adult males is presented in order to delimit the two previously misidentified species.

Illustrated descriptions of the adult male, pupa and fourth instar larva, as well as DNA barcoding results of Chaetocladius (Chaetocladius) elisabethae sp. nov. in comparison with closely related species of Chaetocladius s. str. from the Moscow Region are provided. A reference 658 bp barcode sequence from a fragment of the mitochondrial gene cytochrome oxidase I (COI) was used as a tool for species delimitation. Comparisons with corresponding regions of COI between C. (s. str.) elisabethae sp. nov. and other species of the subgenus produced K2P genetic distances of 0...

Lasiurus ebenus was known only from the holotype, which was collected in 1991, in an Atlantic Forest remnant of Ilha do Cardoso State Park, southeastern Brazil. The species was described based on qualitative and quantitative morphological features. Since its original description, based on a single individual, the taxonomic status of Lasiurus ebenus has been questioned. Here we report a second record for the species that comes from Carlos Botelho State Park, São Paulo, ca. 100 km north from the type locality...

Baird et al. (2015) split Lasiurus into three distinct genera (Aeorestes, Dasypterus and Lasiurus) based on tree topology and divergence times for the tribe Lasiurini. This arrangement has not been widely adopted by the scientific community and was criticized by Ziegler et al. (2016). More recently, Baird et al. (2017) reinforced the taxonomic arrangement of Lasiurini comprised by three genera. Baird et al. (2015, 2017) provided the most comprehensive phylogenetic analyses of Lasiurus and offer important insights on the phylogeny and alpha-taxonomy of the group...

Stenochironomus munteanpurin sp. n. is described and illustrated in all life stages, except eggs, from Brazil. The male is very similar to Stenochironomus quadrinotatus Borkent, 1984 due to same overall pattern of pigmentation. The new species can be distinguished from the other related species principally in immature stages: larva with labral lamella arranged in two groups with one or two conical-shaped teeth, spicules of pecten epipharyngis arranged in a row, unequal and irregularly distributed sizes, SI bifurcated, SII pinnate, SIII pinnate setae and, larval exuviae is compacted; pupa with shagreens being in all TI, less number of hooklets in TII, TVII without shagreens and presence of shagreen in conjunctive III/IV and IV/V...

OBJECTIVE: To compare student performance following a change in laboratory teaching methodology from cadavers to models to virtual dissection table in a musculoskeletal gross anatomy course in a doctor of chiropractic program. METHODS: Three marking periods of laboratory and lecture examination scores from 3 consecutive academic calendar years were evaluated and compared using simple analysis as well as analysis of variance and post hoc t tests. The 1st cohort of students ( n = 352) utilized cadavers...

OBJECTIVE: Muscle variants are common findings in dissection laboratories. These anomalous structures can be relevant in the diagnosis and management of certain conditions and therefore could be incorporated into anatomy curricula at chiropractic colleges. We aimed to create an online resource of muscle variants to facilitate student self-directed learning within this area of study. METHODS: At the time of their discovery during routine educational dissection, muscle variants included in the catalog were documented and subsequent case reports written...

Ruthenium complexes involving sulfoxide ligands can undergo linkage isomerization upon light absorption, accompanied by dramatic changes in their optical properties. These remarkable photochromic properties are sensitive to the nature of the ligand as well as to that of the solvent. We used tandem ion mobility spectrometry coupled to mass spectrometry to gain direct experimental insight into the isomerization pathways connecting the different linkage isomers of an isolated ruthenium complex with two dimethyl-sulfoxide ligands...

International travelers to areas endemic for vector-borne diseases (VBDs) may be at risk of contracting and spreading these diseases. The aim of this study was to evaluate the prevalence of immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies that are specific for Dengue Virus (DV), West Nile Virus (WNV), Chikungunya Virus (CHIKV), or Zika Virus (ZV) in a cohort of international travelers. The study enrolled travelers who attended the Travel Medicine and Migration outpatient service of Local Health Unit of Bari, Italy, in March 2015-June 2017 for counseling and vaccine prophylaxis before travel...

Background: Recent media reports have highlighted the risks to patients that may occur when practitioners in the chiropractic, osteopathy and physiotherapy professions provide services in an unethical or unsafe manner. Yet research on complaints about chiropractors, osteopaths, and physiotherapists is limited. Our aim was to understand differences in the frequency and nature of formal complaints about practitioners in these professions in order to inform improvements in professional regulation and education...

Herein we report on the well-documented, yet not widely known, phenomenon of the self-disproportionation of enantiomers (SDE): the spontaneous fractionation of scalemic material into enantioenriched and -depleted fractions when any physicochemical process is applied. The SDE has implications ranging from the origins of prebiotic homochirality to unconventional enantiopurification methods, though the risks of altering the enantiomeric excess (ee) unintentionally, regrettably, remain greatly unappreciated. While recrystallization is well known as an SDE process, occurrences of the SDE in other processes are much less recognized, e...

DNA barcodes are useful for species discovery and species identification, but obtaining barcodes currently requires a well-equipped molecular laboratory, is time-consuming, and/or expensive. We here address these issues by developing a barcoding pipeline for Oxford Nanopore MinION™ and demonstrate that one flowcell can generate barcodes for ~500 specimens despite the high base-call error rates of MinION™ reads. The pipeline overcomes these errors by first summarizing all reads for the same tagged amplicon as a consensus barcode...

Soft nanomaterials with circularly polarized luminescence (CPL) have been currently attracting great interests. Here, we report a pyrene-containing π-peptide dendrons hydrogel, which showed 1D and 2D nanostructures with varied CPL activities. It was found that the individual dendron formed hydrogels in a wide pH range (3-12) and self-assembled into helices with pH-tuned pitches. Through chirality transfer, the pyrene unit could show CPL originated from both the monomer and excimer bands. When cyclodextrin was introduced, different supra-dendrons were obtained with β-cyclodextrin (PGAc@β-CD) and γ-cyclodextrin (PGAc@γ-CD) through host-guest interactions, respectively...

The prime focus of the present investigation was to optimize statistically the anti-tubercular activity and biomass of fermented food associated Staphylococcus hominis strain MANF2 using Taguchi orthogonal array (OA) and Box-Behnken design (BBD). The anti-tubercular activity of strain MANF2 was determined against Mycobacterium tuberculosis H37Rv using luciferase reporter phase assay. Among varied media examined, the isolate exhibited impressive anti-tubercular activity with paramount relative light unit reduction of >90% in de Man Rogose Sharpe (MRS) broth...

Primates are interpreted to be ancestrally adapted to frugivory, although some modern groups show clear adaptations to other diets. Among them, pitheciids stand out for specifically predating seeds. This dietary specialization is known as sclerocarpy and refers to the extraction of seeds from surrounding hard tissues using the anterior dentition followed by the mastication of seeds by the molars. It has been proposed that Callicebus-Pithecia-Chiropotes-Cacajao represent a morphocline of increasingly specialized anatomical traits for sclerocarpic foraging...
