Background: Multiparametric cardiovascular magnetic resonance (CMR) has an emerging role in non-invasive surveillance of pediatric heart transplant recipients (PHTR). Higher myocardial T2, higher extracellular volume fraction (ECV), and late gadolinium enhancement (LGE) have been associated with adverse clinical outcomes in adult heart transplant recipients. This study's purpose was to investigate the prognostic value of CMR-derived T1- and T2-mapping, ECV, and LGE for clinical outcomes in PHTR.

Ancient DNA (aDNA) data are reported for two human skeletons buried within the chancel of the 1608-1616 church at the North American colonial settlement of Jamestown, Virginia. The men are suspected kinsmen of the colony's first Governor, Thomas West, 3 Baron De La Warr based on archaeological, osteological, and documentary evidence. Genomic analyses of these men, Sir Ferdinando Wenman and Captain William West, identify a shared mitochondrial haplogroup, H10e, inferring maternal relatedness.

School-based consultation or coaching may be used to promote teachers' use of various classroom management practices and interventions. An important aspect of school-based consultation and coaching is ensuring teachers generalize their use of evidence-based practices that were trained through consultation. However, the extent to which teachers generalize practices trained through consultation or coaching is somewhat unclear.

Article Synopsis
  • - The Oxford Haemodynamic Adaptation to Reduce Pulsatility (OxHARP) trial studied the effects of sildenafil on cerebrovascular conditions, finding that it increased cerebrovascular reactivity but didn't reduce cerebral pulsatility, both linked to vascular aging.
  • - This study aimed to see how the severity of white matter hyperintensities (WMH) relates to both cerebral pulsatility and cerebrovascular reactivity in the same group of patients.
  • - Results showed that greater severity of WMH was independently linked to decreased cerebrovascular reactivity and increased cerebral pulsatility, suggesting a complex interaction that warrants further investigation.

  • The Linearbandkeramik (LBK) Neolithic communities were pioneers in spreading agriculture across Europe and this study showcases genetic data from 250 individuals to understand their ancestry.
  • The findings reveal a notable difference in ancestry, with eastern LBK sites having a higher percentage of western hunter-gatherer genetics compared to western sites, indicating separate genetic paths for these groups.
  • Additionally, the research suggests a patrilocal social structure, featuring more genetic connections among males within sites, and points out that the massacre at Asparn-Schletz likely involved individuals from a large population rather than a small community.

Efforts to improve photosynthetic performance are increasingly employing natural genetic variation. However, genetic variation in the organellar genomes (plasmotypes) is often disregarded due to the difficulty of studying the plasmotypes and the lack of evidence that this is a worthwhile investment. Here, we systematically phenotyped plasmotype diversity using as a model species.

During the COVID-19 pandemic, which spanned much of 2020-2023 and beyond, daily case and death counts were recorded globally. In this study, we examined available mortality counts and associated case counts, with a focus on the estimation missing information related to age distributions. In this paper, we explored a model-based paradigm for generating age distributions of mortality counts in a spatio-temporal context.

This paper investigates the link between gaps in emergency responders' notions of mental model regarding radiation and risk and their effectiveness in responding to radiological incidents. Particularly, this work focused on exploring themes that emerged in prior work related to improper understanding and application of knowledge concepts related to radiation risks and Radiological Dispersal Device (RDD) scenarios (Leek et al., 2024b).

Article Synopsis
  • T-2 toxin, a highly toxic trichothecene mycotoxin, was studied using high-resolution magic-angle spinning nuclear magnetic resonance (HRMAS NMR) and zebrafish embryos to explore its toxicity mechanisms.
  • The study found that T-2 exposure resulted in lethality at around 105 ppb and influenced the production of reactive oxygen species (ROS), causing varied ROS levels in different organs.
  • Metabolic profiling indicated significant disturbances in detoxification processes, membrane phospholipids, mitochondrial energy metabolism, and glucose metabolism, leading to a comprehensive understanding of T-2 toxicity for health implications.

Background: Normothermic machine perfusion of donor livers has become standard practice in the field of transplantation, allowing the assessment of organs and safe extension of preservation times. Alongside its clinical uses, there has been expanding interest in extended normothermic machine perfusion (eNMP) of livers as a potential vehicle for medical research. Reproducible extended normothermic machine perfusion has remained elusive due to its increased complexity and monitoring requirements.

  • * The newly developed PAMless Cas enzyme, SpRY, allows for higher efficiency and specificity in correcting X-CGD mutations, particularly through the use of the adenine base editor ABE8e-SpRY, which achieved up to 70% mutation correction in hematopoietic stem and progenitor cells (HSPCs).
  • * Investigations into potential off-target effects showed minimal unintended edits, and the success of these techniques in mouse models supports the initiation of first-in-human

Background: Mediation by multiple agents can affect the relation between neighborhood deprivation and segregation indices and ovarian cancer survival. In this paper, we examine a variety of potential clinical mediators in the association between deprivation indices (DIs) and segregation indices (SIs) with all-cause survival among women with ovarian cancer in the African American Cancer Epidemiology Study (AACES).

Methods: We use novel Bayesian multiple mediation structural models to assess the joint role of mediators (stage at diagnosis, histology, diagnostic delay) combined with the DIs and SIs (Yost, ADI, Kolak's URB, ICE-income) and a set of confounders with survival.

Article Synopsis
  • Identifying high-risk areas for infectious diseases is crucial for effective public health responses, and this paper introduces a new prediction metric using a Bayesian spatio-temporal model.
  • The metric enhances current techniques by combining three key factors: the risk profile of an area, the trend of risk over time, and the influence of neighboring regions, all weighted appropriately for better accuracy.
  • Through simulations, the study confirms that local risk and neighborhood effects significantly enhance sensitivity, while trend analysis improves the specificity and overall predictive accuracy of risk assessments, evidenced by its application to COVID-19 data in South Carolina.

The anatomy of the avian lower respiratory system includes a complex interaction between air-filled pulmonary tissues, pulmonary air sacs, and much of the postcranial skeleton. Hypotheses related to the function and phylogenetic provenance of these respiratory structures have been posed based on extensive interspecific descriptions for an array of taxa. By contrast, intraspecific descriptions of anatomical variation for these features are much more limited, particularly for skeletal pneumatization, and are essential to establish a baseline for evaluating interspecific variation.

In the context of designing innovative anticancer agents, the synthesis of a series of chalcones bearing a 3,4,5-trimethoxylated A ring and a variety of B rings, including phenols and original heterocycles such as chromones, was conducted. For this end, Claisen-Schmidt condensation was performed in basic or acidic conditions between the common starting material 3,4,5-trimethoxyacetophenone and appropriate aldehydes; this allowed the recovery of fifteen chalcones in moderate-good yields. The synthesized compounds were screened for their antiproliferative activity against colorectal and prostatic cancer cells, using a colorimetric MTT assay.

In Brief: Transgender and gender-diverse (TGD) people have similar desires for parenting as cisgender individuals but are likely to face greater barriers in accessing fertility treatment than their cisgender peers. Mental health professionals are well-positioned to advocate for and support TGD individuals seeking fertility care through pre-fertility treatment implications counseling regarding the psychosocial aspects of fertility treatment and family building.

Abstract: Transgender and gender-diverse (TGD) individuals experience significantly greater all-cause mortality and mental health disparities compared to their cisgender peers.

Objective: Lumbar medial branch (MB) radiofrequency ablation is a common intervention to treat facetogenic low back pain. Consensus among spine pain interventionalists is that the cannula tip should be placed adjacent to the periosteum of the lateral neck of the superior articular process (SAP) to ensure maximum contact with the MB. The spatial relationship of the nerve to the periosteum of the lateral neck of the SAP has not been quantified in 3D.
