The Other "A" Word: Assessing the Accessibility of Abortion in Academia.

Objective: To assess the accessibility of abortion providers across collegiate campuses in the State of Colorado. Participants: Analysis was on secondary data from the Integrated Postsecondary Data System and the U.S. Census Bureau. Methods: We utilized a framework of Reproductive Justice to assess and interpret the accessibility of abortion providers to college students by mapping reproductive health centers and nonprofit institutions of higher education, then using these data to statistically compare racial demographics, female employment, and insurance coverage between institutions with and without access. Results: Of nonprofit postsecondary institutions in Colorado, 11 institutions lack access, serving ∼38,900 students. Of these students, 88.7% attend a Minority Serving Institution (MSI). MSIs lacking abortion access had 8% more female enrollment [t(18.32) = -2.04, p = 0.027]. Campuses possessing student health centers are less likely to have an MSI designation (50% with vs. 82% without), have greater female Hispanic enrollment by 10% [t(23.72) = 3.11, p = 0.005] and lower female multiracial enrollment by 2% [t(37.00) = 2.20, p = 0.034]. Analysis of variance (ANOVA) results indicated significant differences in percent composition of Asian, black or African American, Two or More, and Nonresident demographics between collegiate campuses with 30-, 45-, and 60-minute drive-time access. ANOVA results indicated separate patterns of differences for Zip Code Tabulation Area (ZCTA) demographics for Asian, black or African American, Native Hawaiian or Pacific Islander, Other Race, and Nonresident populations. Planned contrasts demonstrated that this difference was greatest at the 30-minute drive-time access, supporting the use of 30-minute drive time as an important indicator of access. Conclusions: The colleges lacking access to a provider are predominantly MSIs in lower income communities. The patterns in campus and ZCTA demographics indicate that collegiate populations are affected by rurality differently than the general population. We recommend that future qualitative research to assess rural students' perceptions on access, campus health center practices, and practices on campuses without dedicated health facilities.

Validation of DNA marker-assisted selection for forage biomass productivity under deficit irrigation in alfalfa.

Drought and limited irrigation resources threaten agricultural sustainability in many regions of the world. Application of genomic-based breeding strategies may benefit crop variety development for these environments. Here, we provide a first report on the effect of deploying DNA marker-assisted selection (MAS) for the drought resilience quantitative trait in alfalfa (Medicago sativa L.). The goals of this study were to validate the effect of several quantitative trait loci (QTL) associated with alfalfa forage and crown-root (CR) biomass during drought and to determine their potential to improve forage yield of elite germplasm under water-limited conditions. Marker assisted selection was employed to introgress favorable or unfavorable DNA marker alleles affiliated with 10 biomass QTL into three elite backgrounds. Thirty-two populations were developed and evaluated for forage productivity over 3 yr under continuous deficit irrigation management in New Mexico, USA. Significant yield differences (ranging from -13 to 26%) were detected among some MAS-derived populations in all three elite backgrounds. Application of QTL MAS generally resulted in expected phenotypic responses within an elite genetic background that was similar to that in which the QTL were originally identified. However, relative performance of the populations varied substantially across the three genetic backgrounds. These outcomes indicate that QTL MAS can significantly affect forage productivity of elite alfalfa germplasm in drought-stressed environments. However, if biomass QTL are detected in donor germplasm that is genetically dissimilar to targeted elite populations, characterization of donor alleles may be warranted within elite backgrounds of interest to confirm their phenotypic effects prior to implementing MAS-based breeding.

Strategies to Increase Prediction Accuracy in Genomic Selection of Complex Traits in Alfalfa (Medicago sativa L.).

Agronomic traits such as biomass yield and abiotic stress tolerance are genetically complex and challenging to improve through conventional breeding approaches. Genomic selection (GS) is an alternative approach in which genome-wide markers are used to determine the genomic estimated breeding value (GEBV) of individuals in a population. In alfalfa (Medicago sativa L.), previous results indicated that low to moderate prediction accuracy values (<70%) were obtained in complex traits, such as yield and abiotic stress resistance. There is a need to increase the prediction value in order to employ GS in breeding programs. In this paper we reviewed different statistic models and their applications in polyploid crops, such as alfalfa and potato. Specifically, we used empirical data affiliated with alfalfa yield under salt stress to investigate approaches that use DNA marker importance values derived from machine learning models, and genome-wide association studies (GWAS) of marker-trait association scores based on different GWASpoly models, in weighted GBLUP analyses. This approach increased prediction accuracies from 50% to more than 80% for alfalfa yield under salt stress. Finally, we expended the weighted GBLUP approach to potato and analyzed 13 phenotypic traits and obtained similar results. This is the first report on alfalfa to use variable importance and GWAS-assisted approaches to increase the prediction accuracy of GS, thus helping to select superior alfalfa lines based on their GEBVs.

Social contact behaviors are associated with infection status for Trichuris sp. in wild vervet monkeys (Chlorocebus pygerythrus).

Social grooming in the animal kingdom is common and serves several functions, from removing ectoparasites to maintaining social bonds between conspecifics. We examined whether time spent grooming with others in a highly social mammal species was associated with infection status for gastrointestinal parasites. Of six parasites detected, one (Trichuris sp.) was associated with social grooming behaviors, but more specifically with direct physical contact with others. Individuals infected with Trichuris sp. spent significantly less time grooming conspecifics than those not infected, and time in direct contact with others was the major predictor of infection status. One model correctly predicted infection status for Trichuris sp. with a reliability of 95.17% overall when the variables used were time spent in direct contact and time spent grooming others. This decrease in time spent grooming and interacting with others is likely a sickness behavior displayed by individuals with less energy or motivation for non-essential behaviors. This study emphasizes the possible links between host behavior and parasitic infections and highlights the need for an understanding of a study population's parasitic infections when attempting to interpret animal behavior.

The Information Gap for Children and Young People with Acquired Brain Injury.

Statement of Purpose: This study explored the information requirements of children/youth with an acquired brain injury.Methods: An online survey (n = 16), focus group (n = 5) and in-depth semi-structured interviews (n = 3) elicited the views of 24 children/youth with ABI. A priori thematic coding was used to analyze the data.Results: Five themes emerged: stage and age, school, friendship and peers, delivery methods and information content. The desired information changes over time depending on age and time since the injury. Children/youth want their friends and teachers to access information on brain injury. Children/youth want information delivered through a range of channels, including videos (featuring genuine case studies), apps and board games. Children/youth wanted information specific to their injury, information on brain injury more generally, and practical strategies for overcoming problems.Conclusions: Children/youth with ABI were able to express views about their information needs, which change over time and include a range of channels.

Transcriptome responses in alfalfa associated with tolerance to intensive animal grazing.

Tolerance of alfalfa (Medicago sativa L.) to animal grazing varies widely within the species. However, the molecular mechanisms influencing the grazing tolerant phenotype remain uncharacterized. The objective of this study was to identify genes and pathways that control grazing response in alfalfa. We analyzed whole-plant de novo transcriptomes from grazing tolerant and intolerant populations of M. sativa ssp. falcata subjected to grazing by sheep. Among the Gene Ontology terms which were identified as grazing responsive in the tolerant plants and differentially enriched between the tolerant and intolerant populations (both grazed), most were associated with the ribosome and translation-related activities, cell wall processes, and response to oxygen levels. Twenty-one grazing responsive pathways were identified that also exhibited differential expression between the tolerant and intolerant populations. These pathways were associated with secondary metabolite production, primary carbohydrate metabolic pathways, shikimate derivative dependent pathways, ribosomal subunit composition, hormone signaling, wound response, cell wall formation, and anti-oxidant defense. Sequence polymorphisms were detected among several differentially expressed homologous transcripts between the tolerant and intolerant populations. These differentially responsive genes and pathways constitute potential response mechanisms for grazing tolerance in alfalfa. They also provide potential targets for molecular breeding efforts to develop grazing-tolerant cultivars of alfalfa.

Internal conversion in energy dispersive X-ray analysis of actinide-containing materials.

The use of X-ray elemental analysis tools like energy dispersive X-ray (EDS) is described in the context of the investigation of nuclear materials. These materials contain radioactive elements, particularly alpha-decaying actinides that affect the quantitative EDS measurement by producing interferences in the X-ray spectra. These interferences originating from X-ray emission are the result of internal conversion by the daughter atoms from the alpha-decaying actinides. The strong interferences affect primarily the L X-ray lines from the actinides (in the typical energy range used for EDS analysis) and would require the use of the M lines. However, it is typically at the energy of the actinide's M lines that the interferences are dominant. The artifacts produced in the X-ray analysis are described and illustrated by some typical examples of analysis of actinide-bearing material.
