PREMISE OF STUDY: The carnivorous members of the large, hyperdiverse Caryophyllales (e.g., Venus flytrap, sundews, and Nepenthes pitcher plants) represent perhaps the oldest and most diverse lineage of carnivorous plants. However, despite numerous studies seeking to elucidate their evolutionary relationships, the early-diverging relationships remain unresolved. METHODS: To explore the utility of phylogenomic data sets for resolving relationships among the carnivorous Caryophyllales, we sequenced 10 transcriptomes, including all the carnivorous genera except those in the rare West African liana family Dioncophyllaceae...

The purpose of this study is to develop a method for quantifying the fluidity of flowable resin composites using determinations of yield stress. Five commercially available composites (AliteFlo LV, Flow-it ALC, Venus flow, Tetric N-flow, Revolution Formula2) were investigated. Yield stress values were obtained by plotting shear stresses for a range of shear rates, followed by fitting of Casson fluid models to flow curve data and extrapolation to the stress axis. To confirm that yield stress reflected fluidity, apparent viscosity at the lower shear rate (0...

AIM: We used non-Hirschsprung's disease (HD) Sox10-Venus Transgenic mice (non-HDSV-mice), an endothelin receptor-B knockout mouse model of HD (HD-mice), and C57B6C3 wild controls (C-mice) to identify the correlation between the anorectal line (ARL) and successful transanal pull-through (TAPT). METHODS: In non-HDSV-mice, intestinal neural crest-derived cells can be visualized with Venus,-a green fluorescent protein-without histochemical staining. We exposed the anal canal in each non-HDSV-mouse and marked the ARL directly with red ink...

This work concerns the investigation of the sequential production of lactic acid (LA) and biogas from food waste (FW). LA was produced from FW using a Streptococcus sp. strain via simultaneous saccharification and fermentation (SSF) and separate enzymatic hydrolysis and fermentation (SHF). Via SHF a yield of 0.33gLA/gFW (productivity 3.38gLA/L·h) and via SSF 0.29gLA/gFW (productivity 2.08gLA/L·h) was obtained. Fermentation residues and FW underwent anaerobic digestion (3wt% TS). Biogas yields were 0.71, 0...

BACKGROUND: Reducing HIV mother-to-child transmission (MTCT) is critical to ending the HIV pandemic. Reports suggest that herpes simplex virus-2 (HSV-2), a common coinfection in HIV-infected individuals, is associated with increased MTCT, but results have been conflicting. We conducted a systematic review of observational studies to quantify the magnitude of this relationship (PROSPERO no. CRD42016043315). METHODS: We searched Medline (1981 to June week 3, 2016), EMBASE (1981 to week 26, 2016), relevant conferences (2013-2016) and bibliographies of identified studies for cohort and case-control studies enrolling HIV-positive women during pregnancy or peripartum that quantified the effect of HSV-2 infection on MTCT...

OBJECTIVE: The transcription factors (TF) Foxa2 and Pdx1 are key regulators of beta-cell (β-cell) development and function. Mutations of these TFs or their respective cis-regulatory consensus binding sites have been linked to maturity diabetes of the young (MODY), pancreas agenesis, or diabetes susceptibility in human. Although Foxa2 has been shown to directly regulate Pdx1 expression during mouse embryonic development, the impact of this gene regulatory interaction on postnatal β-cell maturation remains obscure...

Phagosome formation and maturation are essential innate immune mechanisms to engulf and digest foreign particles. To analyze these processes quantitatively, we established a specific Escherichia coli probe expressing a tandem fluorescent protein, comprising glutathione S-transferase fused with monomeric Cherry (mCherry) and monomeric Venus (mVenus). We demonstrated that mVenus was more susceptible to bleaching in an acidic environment than mCherry, and that the mVenus:mCherry fluorescence intensity ratio can be used to monitor phagosomal pH changes during maturation...

Making use of a source previously unknown to historians, this article sheds new light on the British expedition to the Sandwich Islands to observe the 1874 transit of Venus. This source, a series of caricature drawings that follow the expedition from departure to return, gives insight into expeditionary culture and the experience of a previously unremarked member of this astronomical expedition, Evelyn J.W. Noble, a career officer of the Royal Marine Artillery. It also reveals overlapping military, scientific and masculine identities, developed in dialogue with, and often deliberately subverting, more public accounts...

Dysferlin concentrates in the transverse tubules of skeletal muscle and stabilizes Ca(2+) transients when muscle fibres are subjected to osmotic shock injury (OSI). We show here that voltage-induced Ca(2+) transients elicited in dysferlin-null A/J myofibers are smaller than control A/WySnJ fibres. Regional expression of Venus-dysferlin chimeras in A/J fibres restores the full amplitude of the Ca(2+) transients and protects against OSI. We also show that drugs that target ryanodine receptors (RyR1: dantrolene, tetracaine, S107) and L-type Ca(2+) channels (LTCC: nifedipine, verapamil, diltiazem) prevent the decrease in Ca(2+) transients in A/J fibres following OSI...

The striped venus clams Chamelea gallina and C. striatula are commercially important bivalves inhabiting European and North African coastal waters. The taxonomic status of these taxa has been the subject of debate for decades. In order to elucidate this issue, we generated 5S and 28S ribosomal RNA and H3 histone gene probes and mapped them by fluorescent in situ hybridization to the chromosomes of morphologically identified striped venus clams, collected from four geographically distant Atlantic and Mediterranean populations...

Mark E Huang
With increasing adoption of electronic health records (EHRs) and legislative mandates for its use within the United States, collaboration between physicians and information technology (IT) staff is essential. Current challenges that physicians face include addressing EHR usability, system performance, adequate training, issue resolution, regulatory compliance, and lack of awareness of IT roles. These challenges lead to gaps in communication between clinicians and IT staff. Strategies to improve collaboration between physicians and IT staff include increasing physician involvement with health information technology software development, involvement with legislative regulations and standards, IT project implementation, as well as system stabilization and optimization...

The whooping cough agent, Bordetella pertussis, controls the expression of its large virulence regulon in a coordinated manner through the two-component system BvgAS. BvgS is a dimeric, multi-domain sensor-kinase. Each monomer comprises in succession tandem periplasmic Venus flytrap (VFT) domains, a transmembrane segment, a cytoplasmic Per-ArnT-Sim (PAS) domain, a kinase module and additional phosphorelay domains. BvgS shifts between kinase and phosphatase modes of activity in response to chemical modulators that modify the clamshell motions of the VFT domains...

Transcription factors are involved in cell cycle and apoptosis regulation and thus have a key role in the carcinogenesis of different tumors. Nuclear factor of activated T-cells, cytoplasmic 2 (NFATc2) and peroxisome proliferator-activated receptor gamma (PPARG) transcription factors are important in the carcinogenesis of colorectal cancer (CRC). In this study, we examined whether the expression of NFATc2 and PPARG genes is significantly altered during the carcinogenesis of CRC. A total of 47 tumor samples and matched normal tissue margins were collected during surgery from patients with CRC...

The global geodynamic regime of early Earth, which operated before the onset of plate tectonics, remains contentious. As geological and geochemical data suggest hotter Archean mantle temperature and more intense juvenile magmatism than in the present-day Earth, two crust-mantle interaction modes differing in melt eruption efficiency have been proposed: the Io-like heat-pipe tectonics regime dominated by volcanism and the "Plutonic squishy lid" tectonics regime governed by intrusive magmatism, which is thought to apply to the dynamics of Venus...

There are three specific regions in the Amyloid beta (Aβ) peptide sequence where variations cause enhanced toxicity in Alzheimer's disease: the N-terminus, the central salt bridge, and the C-terminus. Here, we investigate if there is a close conformational connection between these three regions, which may suggest a concerted mechanism of toxicity. We measure the effects of Zn(2+) and curcumin on Aβ40, and compare these with their previously reported effects on Aβ42. Aβ42 and Aβ40 differ only near the C-terminus, where curcumin interacts, while Zn(2+) interacts near the N-terminus...
