Reference populations are valuable resources in genetics studies for determining marker order, marker selection, trait mapping, construction of large-insert libraries, cross-referencing marker platforms, and genome sequencing. Reference populations can be propagated indefinitely, they are polymorphic and have normal segregation. Described are two new reference populations who share the same parents of the original wheat reference population Synthetic W7984 (Altar84/ Aegilops tauschii (219) CIGM86.940) x Opata M85, an F(1)-derived doubled haploid population (SynOpDH) of 215 inbred lines and a recombinant inbred population (SynOpRIL) of 2039 F(6) lines derived by single-plant self-pollinations. A linkage map was constructed for the SynOpDH population using 1446 markers. In addition, a core set of 42 SSR markers was genotyped on SynOpRIL. A new approach to identifying a core set of markers used a step-wise selection protocol based on polymorphism, uniform chromosome distribution, and reliability to create nested sets starting with one marker per chromosome, followed by two, four, and six. It is suggested that researchers use these markers as anchors for all future mapping projects to facilitate cross-referencing markers and chromosome locations. To enhance this public resource, researchers are strongly urged to validate line identities and deposit their data in GrainGenes so that others can benefit from the accumulated information.

Validating a Case Definition for Transgender Adults Using Administrative Data.
JAMA Netw Open
January 2025
Cumming School of Medicine, University of Calgary, Calgary, Alberta, Canada.
Importance: Administrative health data serve as promising data sources to study transgender health at a population level in the absence of self-reported gender identity.
Objective: To develop and validate case definitions identifying transgender adults in administrative data compared with the reference standard of self-reported gender identity in a universal health care setting.
Design, Setting, And Participants: In this cohort study conducted in Alberta, Canada, data from provincial administrative health data sources including inpatient hospitalizations, emergency department encounters, primary care visits, prescription drug dispensations, and the provincial health insurance registry were linked and used to develop 15 case definitions (9 for transgender women and 6 for transgender men).
How Residual Fertility Impacts the Efficiency of Crop Pest Control by the Sterile Insect Technique.
Bull Math Biol
January 2025
Université Côte d'Azur, Inria, INRAE, CNRS, MACBES, Sophia Antipolis, France.
The sterile insect technique (SIT) is a biological control technique based on mass-rearing, radiation-based sterilization that can induce fitness costs, and releases of the pest species targeted for population control. Sterile matings, between females and sterilized males, can reduce the overall population growth rate and cause a fall in population density. However, a proportion of irradiated males may escape sterilization, resulting in what is called residual fertility.

Recent research shows a significant link between race-ethnicity and income concentration and premature death rates in the U.S. However, most studies focus on Black-White residential concentration, overlooking racial-ethnic diversity.

Advocate Aurora Research Institute, Advocate Health, 945 N 12th St, Milwaukee, WI, 53233, USA.
Introduction: Oral anticoagulants (OAC) reduce the risk of stroke among patients with atrial fibrillation (AF). However, adherence remains suboptimal. We focused on primary nonadherence to OAC and its associations with patient characteristics-specifically social determinants of health collected in electronic health records (EHR).

Mol Biol Rep
January 2025
School of Ocean Science and Engineering, The University of Southern Mississippi, Ocean Springs, MS, 39564, USA.
Background: The gray snapper (Lutjanus griseus) is a marine reef fish commonly found in coastal and shelf waters of the tropical and subtropical western Atlantic Ocean. In this work, a draft reference genome was developed to support population genomic studies of gray snapper needed to assist with conservation and fisheries management efforts.
Methods And Results: Hybrid assembly of PacBio and Illumina sequencing reads yielded a 1,003,098,032 bp reference across 2039 scaffolds with N50 and L50 values of 1,691,591 bp and 163 scaffolds, respectively.
