Divergent Transport Dynamics of Alkylated versus Unsubstituted Polycyclic Aromatic Hydrocarbons at the Air-Water and Sediment-Water Interfaces at a Legacy Creosote Site.

Alkylated polycyclic aromatic hydrocarbons (PAHs) are abundant constituents of many PAH mixtures and contribute to risk at contaminated sites. Despite their abundance, the movement of alkylated PAHs remains understudied relative to unsubstituted PAHs. In the present study, passive sampling devices were deployed in the air, water, and sediments at 11 locations across multiple seasons to capture spatial and temporal variability in the abundance and movement of alkylated PAHs at a Brownsfield creosote site in Oregon, USA.

Mitochondrial uncouplers inhibit oncogenic E2F1 activity and prostate cancer growth.

Mitochondrial uncouplers dissipate proton gradients and deplete ATP production from oxidative phosphorylation (OXPHOS). While the growth of prostate cancer depends on OXPHOS-generated ATP, the oncogenic pathway mediated by the transcription factor E2F1 is crucial for the progression of this deadly disease. Here, we report that mitochondrial uncouplers, including tizoxanide (TIZ), the active metabolite of the Food and Drug Administration (FDA)-approved anthelmintic nitazoxanide (NTZ), inhibit E2F1-mediated expression of genes involved in cell cycle progression, DNA synthesis, and lipid synthesis.

Collaborative learning in older age and the role of familiarity: evidence from the map task.

As we age, learning new knowledge and skills becomes more difficult due to age-related changes to cognition. Learning collaboratively could counteract these changes, and perhaps more so when working with someone familiar. This study examined whether collaborative learning is affected by age and partner familiarity.

The Utility of Baseline Characteristics and [I]MIBG Cardiac Adrenergic System Scintigraphy in Qualifying Patients with Post-Infarction Heart Failure for Implantable Cardioverter-Defibrillator (ICD) Placement.

Post-infarction heart failure with reduced ejection fraction (HFrEF) patients often face persistent risks of sudden cardiac arrest leading to sudden cardiac death. While implanting a cardioverter-defibrillator (ICD) can enhance prognosis, complications and costs limit its widespread use. Current patient qualification criteria, relying on imperfect parameters, require refinement.

Effects of left ventrolateral prefrontal stimulation on forming and maintaining deep and shallow episodic traces.

The levels-of-processing framework, proposing that deep encoding enhances retention, plays a crucial role in episodic memory research. Neuroimaging evidence highlights that increased activity of the left ventrolateral prefrontal cortex during deep encoding predicts subsequent memory success. However, cognitive mechanisms underlying this region's involvement in establishing and consolidating deep and shallow traces remain unclear.

Long-term myocardial performance of the systemic right ventricle during exercise in patients with transposition of the great arteries and atrial switch operation.

Objective: The echocardiographic assessment of the systemic right ventricle (sRV) performance during stress testing is limited and evaluation is not routinely performed. The aim of the study is to investigate sRV myocardial performance at rest and with exercise in patients with complete transposition of the great arteries (dTGA) who have undergone atrial switch operation.

Methods: In a single-center cross-sectional study, 41 patients with dTGA following the atrial switch operation and gender-matched 20 healthy volunteers underwent exercise echocardiography on a bicycle ergometer in the semi-supine position to assess sRV systolic function indices: tricuspid annular plane systolic excursion (TAPSE), right ventricular area change (FAC), global longitudinal strain (GLS) and systemic velocity time integral (VTI).

New functions of pirin proteins and a 2-ketoglutarate: Ferredoxin oxidoreductase ortholog in Bacteroides fragilis metabolism and their impact on antimicrobial susceptibility to metronidazole and amixicile.

The understanding of how central metabolism and fermentation pathways regulate antimicrobial susceptibility in the anaerobic pathogen Bacteroides fragilis is still incomplete. Our study reveals that B. fragilis encodes two iron-dependent, redox-sensitive regulatory pirin protein genes, pir1 and pir2.

"All the Stars Will Be Wells with a Rusty Pulley": Neural Processing of the Social and Pragmatic Content in a Narrative.

Making sense of natural language and narratives requires building and manipulating a situation model by adding incoming information to the model and using the context stored in the model to comprehend subsequent details and events. Situation model maintenance is supported by the default mode network (DMN), but comprehension of the individual moments in the narrative relies on access to the conceptual store within the semantic system. The present study examined how these systems are engaged by different narrative content to investigate whether highly informative, or semantic, content is a particularly strong driver of semantic system activation compared with contextually driven content that requires using the situation model, which might instead engage DMN regions.

Effect of Voltage-Gated K Channel Inhibition by 4-aminopyridine in Spinal Cord Injury Recovery in Zebrafish.

Spinal cord injury (SCI) affects between 250,000 to 500,000 individuals annually. After the initial injury, a delayed secondary cascade of cellular responses occurs causing progressive degeneration and permanent disability. One part of this secondary process is disturbance of ionic homeostasis.

Flexibility in conceptual combinations: A neural network model of gradable adjective modification.

Our ability to combine simple constituents into more complex conceptual combinations is a fundamental aspect of cognition. Gradable adjectives (e.g.

Functional integration and segregation during semantic cognition: Evidence across age groups.

Semantic cognition is underpinned by ventral anterior temporal lobe (vATL) which encodes knowledge representations and inferior frontal gyrus (IFG), which controls activation of knowledge based on the needs of the current context. This core semantic network has been validated in substantial empirical findings in the past. However, it remains unclear how these core semantic areas dynamically communicate with each other, and with other neural networks, to achieve successful semantic processing.

The utility of novel STE parameters in echocardiographic assessment of single ventricle after Fontan palliation.

Unlabelled: Background and aims of the study A functionally single ventricle (FSV) refers to a group of congenital heart defects that are not amenable for biventricular correction. The Fontan operation is utilized as surgical treatment for most of FSV patients. The evaluation of FSV function is extremely difficult due to its unique pathophysiology.

Verbal semantic expertise is associated with reduced functional connectivity between left and right anterior temporal lobes.

The left and right anterior temporal lobes (ATLs) encode semantic representations. They show graded hemispheric specialization in function, with the left ATL contributing preferentially to verbal semantic processing. We investigated the cognitive correlates of this organization, using resting-state functional connectivity as a measure of functional segregation between ATLs.

The neural basis of naturalistic semantic and social cognition.

Decoding social environments and engaging meaningfully with other people are critical aspects of human cognition. Multiple cognitive systems, including social and semantic cognition, work alongside each other to support these processes. This study investigated shared processing between social and semantic systems using neuroimaging data collected during movie-viewing, which captures the multimodal environment in which social knowledge is exchanged.

Is the 2016 ESC diagnostic algorithm useful for assessing the prevalence of chronic heart failure in population-based studies?

Background: Chronic heart failure (CHF) is a major healthcare problem. However, there are no epidemiological studies assessing the prevalence of CHF in the general population with diagnosis based on algorithms recommended for clinical practice.

Aim: The aim of the HF-Pomorskie survey was to assess the prevalence of three basic components of the 2016 ESC diagnostic algorithm for CHF (symptoms, N-terminal pro B-type natriuretic peptide [NT-proBNP], and abnormalities on echocardiography) and to determine whether this algorithm may be applicable to studies in general population samples.

Assessment of mould remediation in a healthcare setting following extensive flooding.

Background: A new hospital building was close to completion when a large pipe carrying clean water broke, causing extensive flooding.

Aim: To determine the flood-associated fungal risk to susceptible patients who would use that building.

Methods: Though standard flood remediation by the builders was relatively straightforward, there was no model for specialist assessment of patient risk due to the flood-associated mould growth.
