Sex-specific fear acquisition following early life stress is linked to amygdala and hippocampal purine and glutamate metabolism.

Early life stress (ELS) can negatively impact health, increasing the risk of stress-related disorders, such as post-traumatic stress disorder (PTSD). Importantly, PTSD disproportionately affects women, emphasizing the critical need to explore how sex differences influence the genetic and metabolic neurobiological pathways underlying trauma-related behaviors. This study uses the limited bedding and nesting (LBN) paradigm to model ELS and investigate its sex-specific effects on fear memory formation.

Functional anatomy and topographical organization of the frontotemporal arcuate fasciculus.

Traditionally, the frontotemporal arcuate fasciculus (AF) is viewed as a single entity in anatomo-clinical models. However, it is unclear if distinct cortical origin and termination patterns within this bundle correspond to specific language functions. We use track-weighted dynamic functional connectivity, a hybrid imaging technique, to study the AF structure and function in two distinct datasets of healthy subjects.

Deficient cell-cell cohesion is linked with lobular localization in simplified models of lobular carcinoma in situ (LCIS).

Lobular carcinoma in situ (LCIS) is a precursor of invasive lobular carcinoma of the breast. LCIS cells lack cell-cell cohesion due to the loss of E-cadherin. LCIS cells grow in mammary lobules rather than in ducts.

Distinct impact modes of polygenic disposition to dyslexia in the adult brain.

Brain change trajectories in healthy adults correlate with Alzheimer's related genetic variation and memory decline across life.

Throughout adulthood and ageing our brains undergo structural loss in an average pattern resembling faster atrophy in Alzheimer's disease (AD). Using a longitudinal adult lifespan sample (aged 30-89; 2-7 timepoints) and four polygenic scores for AD, we show that change in AD-sensitive brain features correlates with genetic AD-risk and memory decline in healthy adults. We first show genetic risk links with more brain loss than expected for age in early Braak regions, and find this extends beyond APOE genotype.

Benefits and harms associated with the use of AI-related algorithmic decision-making systems by healthcare professionals: a systematic review.

To address this gap, this systematic review assesses the benefits and harms associated with AI-related algorithmic decision-making (ADM) systems used by healthcare professionals, compared to standard care.

Methods: In accordance with the PRISMA guidelines, we included interventional and observational studies published as peer-reviewed full-text articles that met the following criteria: human patients; interventions involving algorithmic decision-making systems, developed with and/or utilizing machine learning (ML); and outcomes describing patient-relevant benefits and harms that directly affect health and quality of life, such as mortality and morbidity.

Multi-Omic Data Integration Suggests Putative Microbial Drivers of Aetiopathogenesis in Mycosis Fungoides.

Background: Mycosis fungoides (MF) represents the most prevalent entity of cutaneous T cell lymphoma (CTCL). The MF aetiopathogenesis is incompletely understood, due to significant transcriptomic heterogeneity and conflicting views on whether oncologic transformation originates in early thymocytes or mature effector memory T cells. Recently, using clinical specimens, our group showed that the skin microbiome aggravates disease course, mainly driven by an outgrowing, pathogenic strain carrying the virulence factor spa, which was shown by others to activate the T cell signalling pathway NF-κB.

The regulatory interplay between miRNA and DNA methylation orchestrates vital ovarian functions and associated traits in PCOS.

Polycystic ovary syndrome (PCOS) is the leading cause of amenorrhea and anovulatory infertility in women of reproductive age. Both gene polymorphisms and tissue-specific epigenetic alterations, which determine gene transcription and translation dynamics in disease-states, strongly influence PCOS development. Particularly, promoter-proximal DNA methylation and microRNA expression changes show strong associations with follicular defects, suggesting post-transcriptional dysregulation of localized gene networks.

Identification of differentially expressed genes in human testis biopsies with defective spermatogenesis.

Purpose: Sperm morphology and motility are major contributors to male-factor infertility, with many genes predicted to be involved. This study aimed to elucidate differentially expressed transcripts in human testis tissues of normal and abnormal spermatogenesis that could reveal new genes that may regulate sperm morphology and function.

Methods: Human testis biopsies were collected from men with well-characterized phenotypes of normal spermatogenesis, spermatid arrest, and Sertoli cell-only phenotype, and transcriptional differences were quantified by RNA-sequencing (RNA-Seq).

Large-scale georeferenced neuroimaging and psychometry data link the urban environmental exposome with brain health.

This study aims to develop and validate an interpretable model that can predict apneas and hypopneas.

π-HuB: the proteomic navigator of the human body.

The human body contains trillions of cells, classified into specific cell types, with diverse morphologies and functions. In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies.

Metastability demystified - the foundational past, the pragmatic present and the promising future.

Healthy brain function depends on balancing stable integration between brain areas for effective coordinated functioning, with coexisting segregation that allows subsystems to express their functional specialization. Metastability, a concept from the dynamical systems literature, has been proposed as a key signature that characterizes this balance. Building on this principle, the neuroscience literature has leveraged the phenomenon of metastability to investigate various aspects of brain function in health and disease.
