Pre-breeding in alfalfa germplasm develops highly differentiated populations, as revealed by genome-wide microhaplotype markers.

Plant genebanks contain large numbers of germplasm accessions that likely harbor useful alleles or genes absent in commercial plant breeding programs. Broadening the genetic base of commercial alfalfa germplasm with these valuable genetic variations can be achieved by screening the extensive genetic diversity in germplasm collections and enabling maximal recombination among selected genotypes. In this study, we assessed the genetic diversity and differentiation of germplasm pools selected in northern U.

Autonomous ribosome biogenesis in vitro.

Ribosome biogenesis is pivotal in the self-replication of life. In Escherichia coli, three ribosomal RNAs and 54 ribosomal proteins are synthesized and subjected to cooperative hierarchical assembly facilitated by numerous accessory factors. Realizing ribosome biogenesis in vitro is a critical milestone for understanding the self-replication of life and creating artificial cells.

Diet-wide analyses for risk of colorectal cancer: prospective study of 12,251 incident cases among 542,778 women in the UK.

Uncertainty remains regarding the role of diet in colorectal cancer development. We examined associations of 97 dietary factors with colorectal cancer risk in 542,778 Million Women Study participants (12,251 incident cases over 16.6 years), and conducted a targeted genetic analysis in the ColoRectal Transdisciplinary Study, Colon Cancer Family Registry, and Genetics and Epidemiology of Colorectal Cancer Consortium (GECCO).

Low-temperature vacuum evaporation as a novel dehydration process for the long-term preservation of transplantable human corneal tissue.

Globally there is a shortage of available donor corneas with only 1 cornea available for every 70 needed. A large limitation to corneal transplant surgery is access to quality donor tissue due to inadequate eye donation services and infrastructure in many countries, compounded by the fact that there are few available long-term storage solutions for effectively preserving spare donor corneas collected in countries with a surplus. In this study, we describe a novel technology termed low-temperature vacuum evaporation (LTVE) that can effectively dry-preserve surplus donor corneal tissue, allowing it to be stored for approximately 5 years, shipped at room temperature, and stored on hospital shelves before rehydration prior to ophthalmic surgery.

Exploration of Cytokines and Microbiome Among Males and Females with Diarrhea-Predominant Irritable Bowel Syndrome.

Background: Whether pathophysiological factors differ between males and females with irritable bowel syndrome-diarrhea (IBS-D) remains to be tested. To better understand potential sex differences, males with IBS-D were compared to naturally cycling females and to females with IBS-D taking hormonal contraception on plasma levels of cytokines and gut microbiome characteristics.

Methods: Males and females with Rome III IBS-D completed questionnaires and kept a daily symptom diary for 28 days.

Impact of storage temperature and ultraviolet irradiation on rotavirus survival on food matrices.

This study investigated the survival of human rotavirus (HRV) on fresh beef, chicken, and lettuce stored at various temperatures, as well as the effect of UV-C exposure on HRV viability on these food surfaces. At 20 °C, the survival rate of three HRV strains (WA, 89-12C2, and DS-1) on beef, chicken, and lettuce decreased within 3 days, with the most significant reduction observed on beef. When stored at 4 °C, a significant reduction in HRV viability was observed by day 7, with the greatest decrease observed on beef, followed by chicken and lettuce.

Management of alcohol withdrawal syndromes in general hospital settings.

The covid-19 pandemic was associated with an unprecedented increase in alcohol consumption and associated morbidity, including hospitalizations for alcohol withdrawal. Clinicians based in hospitals must be ready to identify, assess, risk-stratify, and treat alcohol withdrawal with evidence based interventions. In this clinically focused review, we outline the epidemiology, pathophysiology, clinical manifestations, screening, assessment, and treatment of alcohol withdrawal in the general hospital population.

Disseminated enterovirus infection treated with intravenous immunoglobulin in a patient on maintenance ocrelizumab for multiple sclerosis.

We present a case of a woman in her 40s with disseminated enterovirus infection in the setting of maintenance therapy with ocrelizumab for relapsing-remitting multiple sclerosis. The patient originally presented with fever, bilateral lower limb swelling and hypoalbuminaemia. She subsequently developed a productive cough and diarrhoea, and a viral respiratory multiplex panel detected rhino/enterovirus.

Extracorporeal Cardiopulmonary Resuscitation Outcomes in Pre-Glenn Single Ventricle Infants: Analysis of A Ten-Year Dataset.

Background: While several studies have reported on outcomes of extracorporeal membrane oxygenation (ECMO) in patients with single ventricle physiology, few studies have described outcomes of extracorporeal cardiopulmonary resuscitation (ECPR) in this unique population. The objective of this study was to determine survival and risk factors for mortality after ECPR in single ventricle patients prior to superior cavopulmonary anastomosis, using a large sample from the Extracorporeal Life Support Organization (ELSO) Registry.

Methods: We included single ventricle patients who underwent ECPR for in-hospital cardiac arrest (IHCA) between January 2012 and December 2021.

An early precursor CD8 T cell that adapts to acute or chronic viral infection.

This study examines the origin and differentiation of stem-like CD8+ T cells that are essential for sustained T cell immunity in chronic viral infections and cancer and also play a key role in PD-1 directed immunotherapy. These PD-1+ TCF-1+ TOX+ stem-like CD8+ T cells, also referred to as precursors of exhausted T cells, have a distinct program that allows them to adapt to chronic antigen stimulation. Using the mouse model of chronic LCMV infection we found that virus specific stem-like CD8+ T cells are generated early (day 5) during chronic infection suggesting that this crucial fate commitment occurs irrespective of infection outcome.

Multiple Biomarkers to Predict Major Adverse Cardiovascular Events in Patients With Coronary Chronic Total Occlusions.

There are limited tools available to predict the long-term prognosis of persons with coronary chronic total occlusions (CTO). A previously-described blood biomarker panel to predict cardiovascular (CV) events was evaluated in patients with CTO. From 1251 patients in the CASABLANCA study, 241 participants with a CTO were followed for an average of 4 years for occurrence of major adverse CV events (MACE, CV death, non-fatal myocardial infarction or stroke) and CV death/heart failure (HF) hospitalization.

A coarse-grained model of clay colloidal aggregation and consolidation with explicit representation of the electrical double layer.

Knowledge Gap: The aggregation of clay minerals in liquid water exemplifies colloidal self-assembly in nature. These negatively charged aluminosilicate platelets interact through multiple mechanisms with different sensitivities to particle shape, surface charge, aqueous chemistry, and interparticle distance and exhibit complex aggregation structures. Experiments have difficulty resolving the associated colloidal assemblages at the scale of individual particles.

Purpose: Melanoma as a subsequent malignant neoplasm has been described among childhood cancer survivors; however, the risk factors and long-term survival are not well understood.

Methods: We assessed incidence, risk factors, and outcomes for melanoma among participants in the Childhood Cancer Survivor Study cohort. Cumulative incidence and standardized incidence ratios (SIRs) were calculated, and multivariable Cox models were used to determine hazard ratios (HRs) and associated 95% CI for melanoma risk factors.

Demographic Correlates of Autism: How Do Associations Compare Between Diagnosis and a Quantitative Trait Measure?

Prevalence of autism diagnosis has historically differed by demographic factors. Using data from 8224 participants drawn from the Environmental influences on Child Health Outcomes (ECHO) Program, we examined relationships between demographic factors and parent-reported autism-related traits as captured by the Social Responsiveness Scale (SRS; T score > 65) and compared these to relations with parent-reported clinician diagnosis of ASD, in generalized linear mixed effects regression analyses. Results suggested lower odds of autism diagnosis, but not of SRS T > 65, for non-Hispanic Black children (adjusted odds ratio [OR] = 0.

Changes in Diversity, Equity, and Inclusion Activities of Family Medicine Departments.

Background And Objectives: Institutional racism causes worse health outcomes for patients of racial/ethnic minority groups via limited access to health care, disparities in quality of care delivered, and lack of physician diversity. Increased attention to racism in 2020 led many medical institutions to examine their diversity, equity, and inclusion (DEI) efforts. In the context of increased national attention to health equity, this study sought to investigate the current status of DEI infrastructure by evaluating leadership and support related to DEI in family medicine departments in 2020 and 2021.

How Different Are Family Medicine Residents Who Desire Additional Training?

Background And Objectives: Limited knowledge is present regarding how fellowship training correlates with graduate outcomes and whether current residents desire an additional year of residency training. The aim of this study is to examine trends in fellowship training and compare residency and practice outcomes between those interested and those not interested in fellowship training as well as the proportion of residents desiring an additional year of residency training.

Methods: We compared data from the American Board of Family Medicine Initial Certification Questionnaire (2017-2019) to the National Graduate Survey (NGS; 2020-2022).

Oxidative Phosphorylation is a Metabolic Vulnerability of Endocrine Therapy-Tolerant Persister Cells in ER+ Breast Cancer.

Despite adjuvant treatment with endocrine therapies, estrogen receptor-positive (ER+) breast cancers recur in a significant proportion of patients. Recurrences are attributable to clinically undetectable endocrine-tolerant persister cancer cells that retain tumor-forming potential. Therefore, strategies targeting such persister cells may prevent recurrent disease.
