A neurocomputational account of multi-line electronic gambling machines.

Multi-line electronic gambling machines (EGMs) are strongly associated with problem gambling. Dopamine (DA) plays a central role in substance-use disorders, which share clinical and behavioral features with disordered gambling. The structural design features of multi-line EGMs likely lead to the elicitation of various dopaminergic effects within their nested anticipation-outcome structure.

Proteomic profiling of the large-vessel vasculitis spectrum identifies shared signatures of innate immune activation and stromal remodelling.

Background: Takayasu arteritis (TAK) and giant cell arteritis (GCA), the most common forms of large-vessel vasculitis (LVV), can result in serious morbidity. Understanding the molecular basis of LVV should aid in developing better biomarkers and treatments.

Methods: Plasma proteomic profiling of 184 proteins was performed in two cohorts.

Subgroups varying in risk and density highlight the potential for stratified breast cancer screening.

Most breast cancer screening programs rely only on demographic data without considering individual risk factors of the population, which might limit their effectiveness by over- and underscreening specific subgroups. Therefore, the aim of this study is to highlight health and economic disparities in outcomes from such a uniform screening strategy. With the microsimulation model MISCAN, we simulated outcomes of the Dutch screening program considering 16 subgroups varying by their 5-year breast cancer risk and breast density.

Re-encountering the phobic cue within days after a reconsolidation intervention is crucial to observe a lasting fear reduction in spider phobia.

Memory reconsolidation interventions offer an exciting alternative to exposure treatment because they may target fear memories directly, thereby preventing relapse. A previous reconsolidation intervention for spider fear abruptly reduced avoidance behaviour, whereas changes in self-reported fear followed later. In this pre-registered placebo-controlled study, we first aimed to conceptually replicate these effects in spider phobia.

Quantitative imaging of loop extruders rebuilding interphase genome architecture after mitosis.

How cells establish the interphase genome organization after mitosis is incompletely understood. Using quantitative and super-resolution microscopy, we show that the transition from a Condensin to a Cohesin-based genome organization occurs dynamically over 2 h. While a significant fraction of Condensins remains chromatin-bound until early G1, Cohesin-STAG1 and its boundary factor CTCF are rapidly imported into daughter nuclei in telophase, immediately bind chromosomes as individual complexes, and are sufficient to build the first interphase TAD structures.

What Does "Palliative" Mean? Sentiment, Knowledge, and Public Perception Concerning Palliative Care on the Internet since the COVID-19 Pandemic.

Background: Little is known about the public perception of palliative care during and after the pandemic. Assuming that analyzing online language data has the potential to collect real-time public opinions, an analysis of large online datasets can be beneficial to guide future policymaking.

Objectives: To identify long-term effects of the COVID-19 pandemic on the public perception of palliative care and palliative care-related misconceptions on the Internet (worldwide) through natural language processing (NLP).

Real-world infection risk in multiple sclerosis patients on long-term immunomodulatory treatments.

Introduction: Numerous immunomodulatory treatments exist for multiple sclerosis (MS), including those that deplete immune cells (e.g. anti-CD20 medications), relocate immune cells (e.

High-dose intravenous BCG vaccination induces enhanced immune signaling in the airways.

Intradermal Bacillus Calmette-Guérin (BCG) is the most widely administered vaccine, but it does not sufficiently protect adults against pulmonary tuberculosis. Recent studies in nonhuman primates show that intravenous BCG administration offers superior protection against (). We used single-cell analysis of bronchoalveolar lavage cells from rhesus macaques vaccinated via different routes and doses of BCG to identify alterations in the immune ecosystem in the airway following vaccination.

Treatment pattern and clinical outcomes of remdesivir in hospitalized COVID-19 patients with severe chronic kidney disease: a database analysis of acute care hospitals in Japan.

Background: There is limited evidence on clinical outcomes and treatment pattern in Japanese patients with severe chronic kidney disease (CKD), hospitalized for coronavirus disease-2019 (COVID-19). We aimed to describe patient characteristics, treatment pattern, and clinical outcomes in Japanese patients with severe CKD, hospitalized for COVID-19 who received remdesivir (RDV).

Methods: We used the anonymized claims database from Medical Data Vision Co.

Tissue growth as a mechanism for collagen fiber alignment in articular cartilage.

Articular cartilage is distinguished by the unique alignment of type II collagen, a feature crucial for its mechanical properties and function. This characteristic organization is established during postnatal development of the tissue, yet the underlying mechanisms remain poorly understood. In this study, a potential mechanism for type II collagen alignment by cartilage-specific growth from within the tissue was investigated.

Prospective relationships between positive emotion dysregulation and borderline personality disorder features among women experiencing intimate partner violence.

Emotion dysregulation is a core feature of borderline personality disorder (BPD). However, there is a dearth of literature examining the association between the dysregulation of positive emotions and BPD. The present study assesses the reciprocal and longitudinal associations between positive emotion dysregulation and BPD features.

Chemical genomics informs antibiotic and essential gene function in .

The Gram-negative pathogen, , poses a serious threat to human health due to its role in nosocomial infections that are resistant to treatment with current antibiotics. Despite this, our understanding of fundamental biology remains limited, as many essential genes have not been experimentally characterized. These essential genes are critical for bacterial survival and, thus, represent promising targets for drug discovery.

All eukaryotic SMC proteins induce a twist of -0.6 at each DNA loop extrusion step.

Eukaryotes carry three types of structural maintenance of chromosome (SMC) protein complexes, condensin, cohesin, and SMC5/6, which are ATP-dependent motor proteins that remodel the genome via DNA loop extrusion (LE). SMCs modulate DNA supercoiling but remains incompletely understood how this is achieved. Using a single-molecule magnetic tweezers assay that directly measures how much twist is induced by individual SMCs in each LE step, we demonstrate that all three SMC complexes induce the same large negative twist (i.

Treatment patterns and clinical outcomes of immunocompromised patients with COVID-19 receiving remdesivir in the inpatient setting in Japan.

Introduction: Remdesivir (RDV) was approved in Japan for the treatment of coronavirus disease 2019 (COVID-19) in May 2020. However, large-scale research describing the characterized use of RDV in the inpatient setting in Japan is limited. This study aimed to describe the treatment patterns and clinical outcomes of immunocompromised patients with COVID-19 treated with RDV.

Direct Detection of Bound Water in Hydrated Powders of Lysozyme by Differential Scanning Calorimetry.

While exploring the behavior of lysozyme powders at different percentages of rehydration by differential scanning calorimetry, we noticed a small peak persistently on the left of the melting point of bulk water, which, when heating up the system, was always around -10 °C. The intensity of the transition was maximal at 160% rehydration and disappeared at higher values. By comparing the premelting peak properties in HO and DO, we attributed it to freezable water bound on the protein surface.

The promise of CRISPR-associated transposons for bacterial functional genomics.

CRISPR-associated transposons (CASTs) are naturally occurring amalgamations of CRISPR-Cas machinery and Tn7-like transposons that direct site-specific integration of transposon DNA via programmable guide RNAs. Although the mechanisms of CAST-based transposition have been well studied at the molecular and structural level, CASTs have yet to be broadly applied to bacterial genome engineering and systematic gene phenotyping (i.e.

Telomeric transposons are pervasive in linear bacterial genomes.

Eukaryotes have linear DNA and their telomeres are hotspots for transposons, which in some cases took over telomere maintenance. While many bacteria also have linear chromosomes and plasmids, no transposons were known to target bacterial telomeres. Here we show several families of independently evolved telomeric transposons in cyanobacteria and .

An immune suppressive tumor microenvironment in primary prostate cancer promotes tumor immune escape.

Background: Immunotherapy has demonstrated limited activity in prostate cancer to date. This likely reflects an immune suppressive tumor microenvironment (TME), with previous studies suggesting low PD-L1 expression and a sparse immune cell infiltrate. We aimed to further characterise the immune TME in primary prostate cancer and correlate immune subset densities with clinical outcomes.

Discovery of multiple bee-hazardous pesticides in ornamental plants via the Bee-Plex multi-target microsphere screening method.

Exposure to pesticides is one of the main drivers of global bee decline. However, the occurrence of pesticides in bee-attracting crops remains underexposed due to the lack of efficient on-site screening approaches for multi-analyte monitoring. Utilizing color-encoded superparamagnetic microspheres, we constructed a portable 8-plex indirect competitive microsphere-based immunoassay for the simultaneous determination of multiple bee-hazardous residues (Bee-Plex).

Out on a Limb: Testing the Hydraulic Vulnerability Segmentation Hypothesis in Trees Across Multiple Ecosystems.

Plant hydraulic theory states that leaf and stem vulnerability to embolism is coordinated within individual plants. The hydraulic vulnerability segmentation hypothesis (HVSH) predicts higher vulnerability in leaves to protect the stem from hydraulic failure, preserving stem xylem, which is generally more metabolically expensive and slower to regenerate than leaf tissues. However, studies designed to test HVSH have reported wide ranges in vulnerability segmentation (VS), and patterns with the environment have been elusive.
