Amphitropical disjunctions in New World Menthinae: Three Pliocene dispersals to South America following late Miocene dispersal to North America from the Old World.

Premise Of The Study: The subtribe Menthinae (Lamiaceae), with 35 genera and 750 species, is among the largest and most economically important subtribes within the mint family. Most genera of Menthinae are found exclusively in the New World, where the group has a virtually continuous distribution ranging from temperate North America to southern South America. In this study, we explored the presence, timing, and origin of amphitropical disjuncts within Menthinae.

The Apoptotic Crypt Abscess: An Underappreciated Histologic Finding in Gastrointestinal Pathology.

Objectives: To differentiate apoptotic crypt abscesses (ACAs) from neutrophilic crypt abscesses (NCAs).

Methods: Cases with crypt abscesses were classified as containing ACAs, NCAs, or mixed crypt abscesses (MCAs) by H&E staining. Sections were stained with cleaved caspase 3 and myeloperoxidase and recategorized.

With this growing interest, new and interdisciplinary research teams are developing to meet this research need.

Overexpression of SbMyb60 in Sorghum bicolor impacts both primary and secondary metabolism.

Few transcription factors have been identified in C grasses that either positively or negatively regulate monolignol biosynthesis. Previously, the overexpression of SbMyb60 in sorghum (Sorghum bicolor) has been shown to induce monolignol biosynthesis, which leads to elevated lignin deposition and altered cell wall composition. To determine how SbMyb60 overexpression impacts other metabolic pathways, RNA-Seq and metabolite profiling were performed on stalks and leaves.

Determination of electroosmotic and electrophoretic mobility of DNA and dyes in low ionic strength solutions.

Nanocoding, a genome analysis platform, relies on very low ionic strength conditions to elongate DNA molecules up to 1.06 (fully stretched DNA = 1). Understanding how electroosmotic and electrophoretic forces vary, as ionic strength decreases, will enable better Nanocoding devices, or other genome analysis platforms, to be developed.

Audiogram of the mallard duck (Anas platyrhynchos) from 16 Hz to 9 kHz.

The pure-tone thresholds of three mallard ducks were determined from 16 Hz to 9 kHz. The purpose was to determine whether the mallard duck hears infrasound, which then may potentially be used for navigation, similar to how it is proposed that pigeons use it for homing. At a level of 60 dB sound pressure level (re 20 μN/m), their hearing range extends 6.

Impact of schoolchildren's involvement in the design process on the effectiveness of healthy food promotion materials.

Marketing techniques may improve children's vegetable consumption. However, student participation in the design of marketing materials may increase the material's salience, while also improving children's commitment and attitudes towards healthy eating. The impact of student-led design of vegetable promotional materials on choice and consumption was investigated using 1614 observations of students' vegetable choice and plate waste in four public elementary schools in Kearney, Nebraska.

Determination of restriction enzyme activity when cutting DNA labeled with the TOTO dye family.

Optical mapping, a single DNA molecule genome analysis platform that can determine methylation profiles, uses fluorescently labeled DNA molecules that are elongated on the surface and digested with a restriction enzyme to produce a barcode of that molecule. Understanding how the cyanine fluorochromes affect enzyme activity can lead to other fluorochromes used in the optical mapping system. The effects of restriction digestion on fluorochrome labeled DNA (Ethidium Bromide, DAPI, H33258, EthD-1, TOTO-1) have been analyzed previously.

Characterization of Enterohemorrhagic Escherichia coli on Veal Hides and Carcasses.

Transcriptional analysis of defense mechanisms in upland tetraploid switchgrass to greenbugs.

Background: Aphid infestation of switchgrass (Panicum virgatum) has the potential to reduce yields and biomass quality. Although switchgrass-greenbug (Schizaphis graminum; GB) interactions have been studied at the whole plant level, little information is available on plant defense responses at the molecular level.

Results: The global transcriptomic response of switchgrass cv Summer to GB was monitored by RNA-Seq in infested and control (uninfested) plants harvested at 5, 10, and 15 days after infestation (DAI).

Assessment With Children Who Need Augmentative and Alternative Communication (AAC): Clinical Decisions of AAC Specialists.

Purpose: The purpose of this study was to explore how speech-language pathologists (SLPs) who are augmentative and alternative communication (AAC) specialists approach the assessment process for 2 case studies, 1 child with cerebral palsy and 1 with autism spectrum disorder. The aim of the study was to answer the following questions: (a) How do clinicians with expertise approach the AAC assessment process for children with developmental disabilities? (b) Can any initial hypothesis be drawn about how SLPs approach the assessment of children with motor versus social interactive deficits?

Method: This study used a phenomenological qualitative design. The researchers conducted 2 in-depth, semistructured interviews with 8 SLPs who specialized in AAC and self-identified as primarily working with children.

Differentiating Declining Commitment and Breakup Using Commitment to Wed.

The relationship literature describes that declining commitment leads to breakup. The goal of this manuscript is to distinguish declining commitment and breakup to clarify this claim to better understand relationship processes. Data comes from a longitudinal study of heterosexual dating couples ( = 180).

Identification of an orthologous clade of peroxidases that respond to feeding by greenbugs (Schizaphis graminum) in C grasses.

Knowledge of specific peroxidases that respond to aphid herbivory is limited in C4 grasses, but could provide targets for improving defence against these pests. A sorghum (Sorghum bicolor (L.) Moench) peroxidase (SbPrx-1; Sobic.

Insect and plant-derived miRNAs in greenbug (Schizaphis graminum) and yellow sugarcane aphid (Sipha flava) revealed by deep sequencing.

Schizaphis graminum (green bug; GB) and Sipha flava (yellow sugarcane aphid; YSA) are two cereal aphid species with broad host ranges capable of establishing on sorghum (Sorghum bicolor) and several switchgrass (Panicum virgatum) cultivars. Switchgrass and sorghum are staple renewable bioenergy crops that are vulnerable to damage by aphids, therefore, identifying novel targets to control aphids has the potential to drastically improve yields and reduce losses in these bioenergy crops. Despite the wealth of genomic and transcriptomic information available from a closely related model aphid species, the pea aphid (Acyrthosiphon pisum), similar genomic information, including the identification of small RNAs, is still limited for GB and YSA.

Consequences of Dating for Post-Divorce Maternal Well-Being.

Repartnering has been linked to health benefits for mothers, yet few studies have examined relationship quality in this context. According to the divorce-stress-adaptation perspective, relationship quality may influence the relationship between maternal well-being and dating after divorce. The current study examines the consequences of dating, relationship quality, and dating transitions (breaking up and dating new partners) on maternal well-being (negative affect and life satisfaction).

LAT1 activity of carboxylic acid bioisosteres: Evaluation of hydroxamic acids as substrates.

Large neutral amino acid transporter 1 (LAT1) is a solute carrier protein located primarily in the blood-brain barrier (BBB) that offers the potential to deliver drugs to the brain. It is also up-regulated in cancer cells, as part of a tumor's increased metabolic demands. Previously, amino acid prodrugs have been shown to be transported by LAT1.

Contamination Revealed by Indicator Microorganism Levels during Veal Processing.

During site visits of veal processors, the U.S. Department of Agriculture, Food Safety Inspection Service (FSIS) has reported processing deficiencies that likely contribute to increased levels of veal contamination.

Culturally competent evidence-based behavioral health services for the transgender community: Progress and challenges.

The presence of individuals who identify as transgender has emerged into public awareness in the United States in recent years. Celebrities who publicly transition have expanded the national conversation about gender variation beyond gender and women's studies classrooms and certain specialty health and mental health services. This increased public visibility has been accompanied by increased visibility in the mental health literature, including the publishing of competencies or guidelines for working with clients who identify as transgender by various professional organizations.

Comprehensive School Physical Activity Programming and Activity Enjoyment.

Objectives: The purpose of this study was to examine the effect of a comprehensive school physical activity program (CSPAP) on physical activity enjoyment in children from low-income schools.

LAT-1 activity of meta-substituted phenylalanine and tyrosine analogs.

The transporter protein Large-neutral Amino Acid Transporter 1 (LAT-1, SLC7A5) is responsible for transporting amino acids such as tyrosine and phenylalanine as well as thyroid hormones, and it has been exploited as a drug delivery mechanism. Recently its role in cancer has become increasingly appreciated, as it has been found to be up-regulated in many different tumor types, and its expression levels have been correlated with prognosis. Substitution at the meta position of aromatic amino acids has been reported to increase affinity for LAT-1; however, the SAR for this position has not previously been explored.

The diverse vocational experiences of five individuals returning to work after severe brain injury: A qualitative inquiry.

Objective: The researchers explored the return-to-work experiences of five adults with severe traumatic brain injuries (TBIs) and those associated with them by performing a qualitative, multiple case study investigation involving in-depth, semi-structured interviews. Selection of this qualitative methodology allowed for personal, individualized accounts of adults with TBI returning to work. Specifically, this methodology promoted accurate representation of the idiosyncratic nature of each participant's experiences.
