September 2024

Department of Upper GI Surgery, Salford Royal Hospital, Stott Lane, Salford, UK; Division of Cancer Sciences, School of Medical Sciences, University of Manchester, UK.

Oesophageal adenocarcinoma (OAC) is amongst the most lethal cancers worldwide, with poor treatment response leading to low survival rates. Recent improvements have been achieved by including the tumour microenvironment (TME) and patients' immune profiles in treatment decisions. We already know that patients with immune-enriched/inflamed TME have better survival outcomes.

High-resolution modeling of aqueous humor dynamics in the conventional outflow pathway of a normal human donor eye.

Comput Methods Programs Biomed

November 2024

Department of Ophthalmology, Boston University School of Medicine, Boston, MA, United States; Department of Anatomy and Neurobiology, Boston University School of Medicine, Boston, MA, United States.

Background And Objective: The conventional aqueous outflow pathway, which includes the trabecular meshwork (TM), juxtacanalicular tissue (JCT), and inner wall endothelium of Schlemm's canal (SC) and its basement membrane, plays a significant role in regulating intraocular pressure (IOP) by controlling aqueous humor outflow resistance. Despite its significance, the biomechanical and hydrodynamic properties of this region remain inadequately understood. Fluid-structure interaction (FSI) and computational fluid dynamics (CFD) modeling using high-resolution microstructural images of the outflow pathway provides a comprehensive method to estimate these properties under varying conditions, offering valuable understandings beyond the capabilities of current imaging techniques.

As neutron yields increase at fusion facilities, a universal symptom the community must deal with is MeV neutron-induced backgrounds in cables running to diagnostics. On the first Gain >1 plasmas in the world, the National Ignition Facility (NIF) neutron time-of-flight (nToF) diagnostic registered significant cable backgrounds that compromised key performance measurements. The South Pole nToF is uniquely located inside the NIF Target Bay shield walls, ∼18 m from the fusion source, and consequently has long coaxial cable runs (>20 m) that see significant neutron fluence.

Background: clinical guidelines recommend initiation of antiviral therapy as soon as possible for patients hospitalized with confirmed or suspected influenza.

Methods: A multicenter US observational sentinel surveillance network prospectively enrolled adults (aged ≥18 years) hospitalized with laboratory-confirmed influenza at 24 hospitals during October 1, 2022-July 21, 2023. A multivariable proportional odds model was used to compare peak pulmonary disease severity (no oxygen support, standard supplemental oxygen, high-flow oxygen/non-invasive ventilation, invasive mechanical ventilation, or death) after the day of hospital admission among patients starting oseltamivir treatment on the day of admission (early) versus those who did not (late or not treated), adjusting for baseline (admission day) severity, age, sex, site, and vaccination status.

Transcranial alternating current stimulation (ctACS) has the potential to be an appealing, non-invasive treatment option for psychiatric and neurological disorders. However, its potential has been limited by significant knowledge gaps in the details and mechanisms of how ctACS affects cerebellar output on single cell and population levels. We investigated this issue by making single-unit recordings of Purkinje cells (PC) and lateral cerebellar nuclear (Lat CN) cells in response to ctACS in anesthetized adult female Sprague-Dawley rats.

Article Synopsis
  • Recent studies indicate that performance on cognitive control tasks stems largely from a task-general efficiency of evidence accumulation (EEA), which is the ability to gather relevant evidence for the task.
  • However, findings from the Adolescent Brain Cognitive Development (ABCD) Study suggest that EEA estimates from conflict recognition tasks show inconsistencies, particularly in how individuals respond to familiar stimuli instead of goal-relevant ones.
  • A new model proposed distinguishes between EEA linked to task goals and use of familiarity, revealing that while EEA correlates strongly across tasks, it shows significant developmental differences and greater reliability compared to familiarity-based processing.

Background: Bronchoalveolar lavage (BAL) is essential in determining the efficacy of novel therapies in alpha-1 antitrypsin deficiency (AATD). These require initial proof-of-concept demonstration that treatment administration increases alpha-1 antitrypsin (AAT) levels and/or anti-neutrophil elastase inhibitory capacity (ANEC) in the lung. Early-phase studies often encounter high interindividual variability of BAL results, primarily stemming from the inherent dilution characteristics of returned BAL fluid.
