Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Basic Science and Pathogenesis.

Background: Nitric oxide (NO) is involved in synaptic transmission and cerebral plasticity, playing a role in the memory process. However, in states of brain inflammation, hypoxia, or ischemia, there is induction of inducible nitric oxide synthase (iNOS) expression by astrocytes and pyramidal cells in the brain. Under conditions of chronic activation, there is a decoupling of iNOS dimers, leading to a massive generation of superoxide anion and peroxynitrite, O2.

Invasion of glioma cells through confined space requires membrane tension regulation and mechano-electrical coupling via Plexin-B2.

Glioblastoma (GBM) is a malignant brain tumor with diffuse infiltration. Here, we demonstrate how GBM cells usurp guidance receptor Plexin-B2 for confined migration through restricted space. Using live-cell imaging to track GBM cells negotiating microchannels, we reveal endocytic vesicle accumulation at cell front and filamentous actin assembly at cell rear in a polarized manner.

Contemporary practices in abdominoperineal resection for early-stage rectal cancer in the United States.

Aim: In contrast to significant advances in organ preservation in locally advanced rectal cancer, the contemporary management of early-stage rectal cancer, including the frequency of abdominoperineal resections, remains largely unexplored in the United States. Therefore, we assessed the utilization of neoadjuvant therapy and oncological resections in early-stage rectal cancer patients.

Study Design: This is a retrospective cohort study of patients with cT1-T3N0 rectal cancer who underwent proctectomies between 2016 and 2022 in the National Surgical Quality Improvement Project proctectomy files.

The landscape of chemokine and cytokine is associated with the distinct clinical status of leprosy patients and their respective household contacts.

Introduction: Leprosy, a chronic infectious disease, is closely linked to the host immune response. According to the WHO, leprosy patients (L) and household contacts (HHC) are classified into subgroups: paucibacillary (PB) and multibacillary (MB), witch reflect the degree of infection in patients and the level of exposure of their contacts. The main goal of this study was to: i) establish a comprehensive overview of soluble mediator signatures of PBMCs upon antigen-specific stimuli and ii) identify whether the chemokine (CH) and cytokine (CY) signatures were associated with distinct clinical manifestations in (L) and immune response profiles in (HHC).

Efficacy and safety of tirofiban in acute ischemic stroke due to intracranial atherosclerotic disease for patients undergoing endovascular treatment: a systematic review and meta-analysis.

Purpose: Tirofiban has emerged as an adjunct therapy for acute ischemic stroke (AIS) patients undergoing endovascular treatment (EVT). However, its benefits for AIS patients with intracranial atherosclerotic disease (ICAD) remains unclear. This meta-analysis evaluates its efficacy and safety in ICAD-related AIS patients undergoing EVT.

Real-Time Tractography-Assisted Neuronavigation for Transcranial Magnetic Stimulation.

State-of-the-art navigated transcranial magnetic stimulation (nTMS) systems can display the TMS coil position relative to the structural magnetic resonance image (MRI) of the subject's brain and calculate the induced electric field. However, the local effect of TMS propagates via the white-matter network to different areas of the brain, and currently there is no commercial or research neuronavigation system that can highlight in real time the brain's structural connections during TMS. This lack of real-time visualization may overlook critical inter-individual differences in brain connectivity and does not provide the opportunity to target brain networks.

Intra and Inter-Test Reliability of Isometric Hip Adduction Strength Test with Force Plates in Professional Soccer Players.

Assessing the reliability of measurement instruments and equipment is essential to ensure the accurate tracking of athletes over extended periods, minimizing the measurement errors caused by chance or other factors.

Spatial associations of Hansen's disease and schistosomiasis in endemic regions of Minas Gerais, Brazil.

Background: Brazil has the second highest case count of Hansen's disease (leprosy, HD), but factors contributing to transmission in highly endemic areas of the country remain unclear. Recent studies have shown associations of helminth infection and leprosy, supporting a biological plausibility for increased leprosy transmission in areas with helminths. However, spatial analyses of the overlap of these infections are limited.

Platelet-Neutrophil aggregate formation induces NLRP3 inflammasome activation in VITT.

Background: Although rare, vaccine-induced thrombotic thrombocytopenia (VITT) following adenoviral vector COVID-19 vaccination is a concerning and often severe adverse effect of vaccination. The generation of high anti-platelet factor 4 (PF4) antibody titers, promotes the formation of immune complexes capable of activating platelets and neutrophils through FcγRIIa.

Objective: Given that Platelet-leukocyte aggregate (PLA) formation and inflammasome activation are common features of thromboinflammatory diseases, we aimed to evaluate if these are also features of VITT.

The effects of secretion removal techniques in premature infants remain a topic of ongoing debate. The aim of the study is to compare two secretion removal techniques in premature infants on mechanical ventilation; : The participants were randomized into conventional chest physiotherapy (CPT; = 22) or expiratory flow increase technique (EFIT; = 21) groups.

Caffeine intake during gestation and lactation causes long-term behavioral impairments in heterogenic mice offspring in a sex-dependent manner.

Growing evidence has indicated a potential association between maternal consumption of caffeine and impaired cognition and behavior in rodent offspring. However, potential sex differences, as well as caffeine-related effects in subsequent generations are still poorly investigated. We aimed to investigate the impact of pre-and/or neonatal exposition to caffeine on the neurodevelopment of male and female mice offspring.
