Protists as determinants of the One Health framework.

One Health connects three main health elements: humans, animals and the environment. Protists influence all three, but their role in the overall One Health framework has been widely overlooked. Here, we highlight the key characteristics that make protists integral to the One Health framework and provide examples on the negative and positive effects of protists on each element.

A cell type-specific expression atlas of small and total RNA in the heart after myocardial infarction.

Acute myocardial infarction (AMI) is a leading cause of mortality worldwide. MicroRNAs (miRNAs), among other small non-coding RNAs, shape the transcriptome and control cellular functions. Although single-cell technologies are now available to study myocardial ischemia response, the study of small RNA regulation is limited by depth of expression, capture efficiency and lack of full coverage of transcripts.

Deep Learning in Knee MRI: A Prospective Study to Enhance Efficiency, Diagnostic Confidence and Sustainability.

Rationale And Objectives: The objective of this study was to evaluate a combination of deep learning (DL)-reconstructed parallel acquisition technique (PAT) and simultaneous multislice (SMS) acceleration imaging in comparison to conventional knee imaging.

Materials And Methods: Adults undergoing knee magnetic resonance imaging (MRI) with DL-enhanced acquisitions were prospectively analyzed from December 2023 to April 2024. The participants received T1 without fat saturation and fat-suppressed PD-weighted TSE pulse sequences using conventional two-fold PAT (P2) and either DL-enhanced four-fold PAT (P4) or a combination of DL-enhanced four-fold PAT with two-fold SMS acceleration (P4S2).

Advancing Myocardial T1 Mapping: A Comparative Study of the Frequency-Independent MFA Sequence and Standard MOLLI.

T1 mapping is essential for detecting myocardial changes, but standard methods like the MOLLI sequence are limited by heart rate dependency and sensitivity to motion artifacts. This study introduces the multiflip angle (MFA) sequence as a novel alternative, aiming to provide frequency-independent and robust T1 mapping, particularly in challenging cardiac conditions. The novel MFA sequence was validated using nickel (II) chloride phantoms and systematically compared with the standard MOLLI sequence in 20 healthy volunteers using a 1.

Incomplete recombination suppression fuels extensive haplotype diversity in a butterfly colour pattern supergene.

Supergenes can evolve when recombination-suppressing mechanisms like inversions promote co-inheritance of alleles at two or more polymorphic loci that affect a complex trait. Theory shows that such genetic architectures can be favoured under balancing selection or local adaptation in the face of gene flow, but they can also bring costs associated with reduced opportunities for recombination. These costs may in turn be offset by rare 'gene flux' between inverted and ancestral haplotypes, with a range of possible outcomes.

Exploring Genetic Influences on Equine Meat Quality: A Bioinformatics Approach.

Horsemeat, known for its high nutritional value and lower environmental impact compared to beef, faces cultural and ethical challenges. Despite its potential, genetic research on horsemeat quality remains limited and no Quantitative Trait Loci (QTLs) have been identified. The aim of this study was to identify and prioritize Single Nucleotide Polymorphism (SNP) markers on the GeneSeek GenomicProfiler™ Equine chip for traits related to meat quality.

Real world federated learning with a knowledge distilled transformer for cardiac CT imaging.

Federated learning is a renowned technique for utilizing decentralized data while preserving privacy. However, real-world applications often face challenges like partially labeled datasets, where only a few locations have certain expert annotations, leaving large portions of unlabeled data unused. Leveraging these could enhance transformer architectures' ability in regimes with small and diversely annotated sets.

Multi-modal dataset creation for federated learning with DICOM-structured reports.

Purpose Federated training is often challenging on heterogeneous datasets due to divergent data storage options, inconsistent naming schemes, varied annotation procedures, and disparities in label quality. This is particularly evident in the emerging multi-modal learning paradigms, where dataset harmonization including a uniform data representation and filtering options are of paramount importance.Methods DICOM-structured reports enable the standardized linkage of arbitrary information beyond the imaging domain and can be used within Python deep learning pipelines with highdicom.

Examining genotype-phenotype associations of GRAM domain proteins using GWAS, PheWAS and literature review in cattle, human, pig, mouse and chicken.

The GRAMD genes are involved in maintaining cholesterol homeostasis, apoptosis, cancer and production traits in livestock. A lipid-binding GRAM domain is implicated in lipid transport and metabolism. The functions of GRAMD proteins remain incompletely understood.

Age-dependent hypertrophy and fibrosis dynamics in hypertrophic cardiomyopathy: Insights from longitudinal CMR studies.

Background: This study aims to evaluate the progression of morphological and functional alterations over time in patients with hypertrophic cardiomyopathy (HCM) using Cardiac Magnetic Resonance (CMR).

Methods: A retrospective analysis was conducted on patients with HCM who underwent serial CMR at 1.5 Tesla.

The Hypolimnas misippus Genome Supports a Common Origin of the W Chromosome in Lepidoptera.

Moths and butterflies (Lepidoptera) have a heterogametic sex chromosome system with females carrying ZW chromosomes and males ZZ. The lack of W chromosomes in early-diverging lepidopteran lineages has led to the suggestion of an ancestral Z0 system in this clade and a B chromosome origin of the W. This contrasts with the canonical model of W chromosome evolution in which the W would have originated from the same homologous autosomal pair as the Z chromosome.

Health and healthcare use of homeless population: Evaluation study of joint social work and healthcare provision.

Background: Homelessness as an extreme form of poverty perpetuates and exacerbates health inequalities. People experiencing homelessness face a mortality rate 10 times higher than that of the general population, with an average age of death at 45. There is a significant disconnect between the mainstream healthcare system and the specific health needs of people experiencing homelessness, leading to substantial human and economic costs.

Malignancy predictors and treatment strategies for adult intestinal intussusception.

Intussusception in adult patients is a rare medical finding, which is accompanied by an underlying tumor in some cases. However, no accepted method has been established to identify patients at risk for tumor-related intussusception. This study aimed to identify imaging features as predictors for tumor-related intussusception.
