Purpose: Little research has focused on the potential impact that the environment plays in shaping cardiac rehabilitation (CR) patient sedentary time (ST) and physical activity (PA). To address this, the current study generated daily path areas (DPAs) based on the locations they visited during and after they completed CR.
Methods: Patients in CR (n = 66) completed a survey and wore an accelerometer and Global Positioning System receiver for 7 days early (first month), late (last 2 weeks of program), and 3 months after completing CR.

Motivation: Accurate prediction of protein side-chain conformations is necessary to understand protein folding, protein-protein interactions and facilitate de novo protein design.
Results: Here we apply torsional flow matching and equivariant graph attention to develop FlowPacker, a fast and performant model to predict protein side-chain conformations conditioned on the protein sequence and backbone. We show that FlowPacker outperforms previous state-of-the-art baselines across most metrics with improved runtime.

In this study, we explored the intricate relationship between Pannexin 1 (PANX1) and the Hippo signaling pathway effector, Yes-associated protein (YAP). Analysis of The Cancer Genome Atlas (TCGA) data revealed a significant positive correlation between PANX1 mRNA and core Hippo components, Yes-associated protein 1 [YAP], Transcriptional coactivator with PDZ-binding motif [TAZ], and Hippo scaffold, Ras GTPase-activating-like protein IQGAP1 [IQGAP1], in invasive cutaneous melanoma and breast carcinoma. Furthermore, we demonstrated that PANX1 expression is upregulated in invasive melanoma cell lines and is associated with increased YAP protein levels.

The frequency of drug-induced liver injury (DILI) in clinical trials remains a challenge for drug developers despite advances in human hepatotoxicity models and improvements in reducing liver-related attrition in preclinical species. TAK-994, an oral orexin receptor 2 agonist, was withdrawn from phase II clinical trials due to the appearance of severe DILI. Here, we investigate the likely mechanism of TAK-994 DILI in hepatic cell culture systems examined cytotoxicity, mitochondrial toxicity, impact on drug transporter proteins, and covalent binding.

Human performance in perceptual and visuomotor tasks is enhanced when stimulus motion follows the laws of gravitational physics, including acceleration consistent with Earth's gravity, g. Here we used a manual interception task in virtual reality to investigate the effects of trajectory shape and orientation on interception timing and accuracy. Participants punched to intercept a ball moving along one of four trajectories that varied in shape (parabola or tent) and orientation (upright or inverted).

The diagnosis of bipolar disorder (BD) in young children has been a topic of debate, in part owing to varied interpretation of manic-like symptoms. We examined how expert academic clinicians participating in the pediatric bipolar biobank varied in their interpretation and application of Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria and diagnoses. Study co-investigators reviewed 12 standardized narratives and for each marked a visual analog scale with their confidence in the presence of manic episodes and criteria.

Purpose: Existing studies documenting cancer-related sexual concerns among hematological cancer patients tend to group all types of hematological cancer together, overlooking potentially unique concerns associated with multiple myeloma (MM). This study is the first to characterize sexuality in MM and to examine predictors of sexual satisfaction for MM, comparatively with participants with other hematological cancer types.
Methods: We conducted a cross-sectional self-report survey-based study.

Objective: Youth with juvenile idiopathic arthritis (JIA) experience elevated rates of internalizing symptoms, although more research is required to understand this phenomenon. Perfectionism, a multidimensional personality trait that involves dimensions such as striving for flawlessness (self-oriented perfectionism) and feeling that others demand perfection (socially-prescribed perfectionism), is a well-known risk factor for internalizing symptoms that has received minimal attention in pediatric populations. Preregistered hypotheses explored the relationships between youth and parent perfectionism and symptoms of depression and anxiety in youth with JIA, as mediated by (a) youth/parent negative self-evaluations and (b) youth self-concealment.

Efficient and flexible responses are essential for successfully interacting with the environment. These interactions require an instantaneous integration of visual stimuli and responses, known as 'stimulus-response binding' (SR binding). SR binding is considered part of a holistic temporary representation, the event file, that integrates the stimulus, the response, and the action effect produced by this response.

Paediatric renal tumours include a broad range of neoplasms which largely differ, but also overlap to a smaller extent, with adult kidney cancer. These include the embryonal tumour nephroblastoma, which accounts for the majority of cases of kidney cancer in the first decade of life and, despite boasting a cure in ~ 90% cases, still presents clinical challenges in a small proportion of cases. A variety of less common mesenchymal tumours, including the mostly indolent congenital mesoblastic nephroma, clear cell sarcoma of kidney which continues to be associated with poor outcomes for higher stage disease, and the typically lethal malignant rhabdoid tumour, form the bulk of the remaining presentations in the first decade.

Background: Referred to as the "forgotten chamber," the right ventricle (RV) is now widely acknowledged as a significant factor, particularly in certain cardiovascular pathologies. Despite historically being undervalued in comparison to the left ventricle, the RV function is deemed crucial in determining patient outcomes following mitral valve (MV) surgery. In the context of MV surgery, it is important to note that the RV is highly susceptible to dysfunction before, during, and after the surgical procedure.

Introduction: Sexual health concerns are common and significantly impact quality of life, but many people do not seek treatment due to embarrassment and other barriers. A biopsychosocial model of assessment and treatment acknowledges the biological, psychological, and social contributors to sexual difficulties and suggests that all these domains should be evaluated.
Objectives: This paper provides an overview of the major psychological factors contributing to sexual difficulties and offer an evidence-based approach for primary care clinicians to assess and treat these issues.

Cerebrospinal fluid (CSF) has emerged as a valuable liquid biopsy source for glioma biomarker discovery and validation. CSF produced within the ventricles circulates through the subarachnoid space, where the composition of glioma-derived analytes is influenced by the proximity and anatomical location of sampling relative to tumor, in addition to underlying tumor biology. The substantial gradients observed between lumbar and intracranial CSF compartments for tumor-derived analytes underscore the importance of sampling site selection.

IDH-mutant low-grade gliomas (LGGs) are slow-growing brain tumors that frequently progress to aggressive high-grade gliomas that have dismal outcomes. In a recent study, Wu and colleagues provide critical insights into the mechanisms underlying malignant progression by analyzing single-cell gene expression and chromatin accessibility across different tumor grades. Their findings support a two-phase model: in early stages, tumors are primarily driven by oligodendrocyte precursor-like cells and epigenetic alterations that silence tumor suppressors like CDKN2A and activate oncogenes such as PDGFRA.

Epithelial cells can become polyploid upon tissue injury, but mechanosensitive cues that trigger this state are poorly understood. Using an Madin Darby Canine Kidney (MDCK) cell knock-out/reconstitution system, we show that α-catenin mutants that alter force-sensitive binding to F-actin or middle (M)-domain promote cytokinesis failure and binucleation, particularly near epithelial wound-fronts. We identified Leucine Zipper Tumor Suppressor 2 (LZTS2), a factor previously implicated in abscission, as a conformation sensitive proximity partner of α-catenin.
