A prospective study of acute propranolol overdose defining dose thresholds of severe toxicity (ATOM - 9).

Introduction: Propranolol is a beta-adrenoceptor blocking drug with sodium channel-blocking properties that can cause life-threatening toxicity in overdose. Limited research defines dose thresholds of toxicity. We aimed to investigate propranolol overdose and dose thresholds for severe toxicity.

Effect of "In Use" Administration on Topical Product Metamorphosis and Skin Permeation of Acyclovir Creams: Implications for Bioequivalence.

Purpose: Typical clinical "in use" conditions for topical semisolids involve their application as a thin film, often with rubbing that can induce metamorphic stress. Yet, product quality and performance tests often characterize the manufactured product, and may not consider product metamorphosis (e.g.

Leg immobilization and subsequent recovery resistance training affect skeletal muscle angiogenesis related markers in young healthy adults regardless of prior resistance training experience.

Unlabelled: We recently reported that resistance trained (T, n=10) and untrained (UT, n=11) young adults experience vastus lateralis (VL) muscle atrophy following two weeks of disuse, and 8 weeks of recovery resistance training (RT) promotes VL hypertrophy in both participant cohorts. However, angiogenesis targets and muscle capillary number were not examined and currently no human studies that have sought to determine if disuse followed by recovery RT affects these outcomes. Thus, we examined whether disuse and/or recovery RT affected these outcomes.

Verruciform Xanthoma Presenting Within an Ear Piercing.

Verruciform xanthomas are rare lesions affecting 0.025-0.5% of the population.

Effects of Patient Gender on Clinicians' Diagnostic Assessment of Youth Disruptive Mood and Behavior.

Objective: Youth disruptive behavior disorders (DBDs) have a male preponderance, but the extent to which gender biases in clinical assessment influence this imbalance remains unclear. The present study investigates whether a child patient's gender affects clinicians' diagnostic decision-making regarding Oppositional Defiant Disorder (ODD), Conduct Dissocial Disorder (CDD), and Intermittent Explosive Disorder (IED).

Method: Clinicians ( = 403; 57.

Small and Long Non-Coding RNA Analysis for Human Trophoblast-Derived Extracellular Vesicles and Their Effect on the Transcriptome Profile of Human Neural Progenitor Cells.

In mice, the fetal brain is dependent upon the placenta for factors that guide its early development. This linkage between the two organs has given rise to the term, the placenta-brain axis. A similar interrelationship between the two organs may exist in humans.

Developmentally regulated generation of a systemic signal for long-lasting defence priming in tomato.

Tomato is a major global crop. However, its production is limited by Botrytis cinerea. Due to the toxicity of postharvest pesticide application, alternative control methods such as priming are being investigated.

Comparative analysis of acute eccentric contraction-induced changes to the skeletal muscle transcriptome in young and aged mice and humans.

Adaptations to skeletal muscle following resistance exercise are due in part to changes to the skeletal muscle transcriptome. Although transcriptional changes in response to resistance exercise occur in young and aged muscles, aging alters this response. Rodent models have served great utility in defining regulatory factors that underscore the influence of mechanical load and aging on changes to skeletal muscle phenotype.

Effects of oxycodone on placental lineages: Evidence from the transcriptome profile of mouse trophoblast giant cells.

Pregnant women are often prescribed or abuse opioid drugs. The placenta is likely the key to understanding how opioids cause adverse pregnancy outcomes. Maternal oxycodone (OXY) exposure of pregnant mice leads to disturbances in the layer of invasive parietal trophoblast giant cells (pTGC) that forms the interface between the placenta and uterus.

A new framework on climate-induced food-security risk for small-scale fishing communities in Tanzania.

Unlabelled: Food insecurity is a pressing issue facing our world, particularly affecting coastal communities who rely on marine resources. The problem is further compounded by the rapidly changing climate, a deteriorating environment and growing human populations. It is essential to evaluate this issue accurately to reduce risk and improve the situation of coastal communities, especially in countries with less socioeconomic development.

The effects of resistance training to near volitional failure on motor unit recruitment during neuromuscular fatigue.

Background: It is unclear whether chronically training close to volitional failure influences motor unit recruitment strategies during fatigue.

Purpose: We compared resistance training to near volitional failure . non-failure on individual motor unit action potential amplitude (MUAP) and surface electromyographic excitation (sEMG) during fatiguing contractions.

Impact of Different Packaging Configurations on A Topical Cream Product.

Purpose: The objective of this study was to investigate whether different dispensing processes can alter the physicochemical and structural (Q3) attributes of a topical cream product, and potentially alter its performance.

Methods: Acyclovir cream, 5% (Zovirax®) is sold in the UK and other countries in a tube and a pump packaging configurations. The structural attributes of the cream dispensed from each packaging configuration were analyzed by optical microscopy, confocal Raman microscopy and cryo-scanning electron microscopy.

Quantitative structure permeability relationships for phenolic compounds applied to human epidermal membranes in various solvents.

Purpose: This study examined how solvent-skin-solute interactions influenced the human epidermal permeation of three similar-sized phenolic compounds applied in a series of different solvents.

Methods: Human epidermal permeation fluxes and lag times of three phenolic compounds were assessed in Franz cells for a range of solvents varying in molecular size and solubility parameters. In order to develop a mechanistic understanding of the determinants of the permeation findings, the solubility of the compounds in solvents and stratum corneum, the extent of solvent uptake by the stratum corneum and the impact of the solvents on skin hydration and transepidermal water loss were also measured.

Using machine learning to predict carotid artery symptoms from CT angiography: A radiomics and deep learning approach.

Purpose: To assess radiomics and deep learning (DL) methods in identifying symptomatic Carotid Artery Disease (CAD) from carotid CT angiography (CTA) images. We further compare the performance of these novel methods to the conventional calcium score.

Methods: Carotid CT angiography (CTA) images from symptomatic patients (ischaemic stroke/transient ischaemic attack within the last 3 months) and asymptomatic patients were analysed.

Fludrocortisone dose-response relationship in septic shock: a randomised phase II trial.

Background: The combination of intravenous hydrocortisone and enteral fludrocortisone may reduce mortality in patients with septic shock. The optimal dose and reliability of absorption of fludrocortisone in critically ill patients are unclear.

Methods: In a multi-centre, open label, phase II randomized clinical trial, intravenous hydrocortisone alone or in combination with one of three doses of enteral fludrocortisone (50 µg, 100 µg or 200 µg daily) for 7 days was compared in patients with septic shock.

Maintaining a Bloodless Field for HeartMate 3 Placement: Splicing an RVAD Outflow Cannula into the CPB Venous Reservoir for Complete LV Emptying.

Over the previous 20 years, the use of extracorporeal membranous oxygenation (ECMO) as a bridge to durable left ventricular assist device (dLVAD) increased significantly. Additionally, emerging literature has demonstrated a protective effect of biventricular decompression while on ECMO, with one such strategy including a temporary LVAD and right ventricular assist device (RVAD). The complexity of these operations is increased by the frequency of re-sternotomies, which result in adhesions and difficult access to traditional cannulation sites.

BP1003 Decreases STAT3 Expression and Its Pro-Tumorigenic Functions in Solid Tumors and the Tumor Microenvironment.

Overexpression and aberrant activation of signal transducer and activator of transcription 3 (STAT3) contribute to tumorigenesis, drug resistance, and tumor-immune evasion, making it a potential cancer therapeutic target. BP1003 is a neutral liposome incorporated with a nuclease-resistant P-ethoxy antisense oligodeoxynucleotide (ASO) targeting the STAT3 mRNA. Its unique design enhances BP1003 stability, cellular uptake, and target affinity.

Skeletal muscle myosin heavy chain fragmentation as a potential marker of protein degradation in response to resistance training and disuse atrophy.

We examined how resistance exercise (RE), cycling exercise and disuse atrophy affect myosin heavy chain (MyHC) protein fragmentation. The 1boutRE study involved younger men (n = 8; 5 ± 2 years of RE experience) performing a lower body RE bout with vastus lateralis (VL) biopsies being obtained prior to and acutely following exercise. With the 10weekRT study, VL biopsies were obtained in 36 younger adults before and 24 h after their first/naïve RE bout.

Androgen receptor markers do not differ between nonresponders and responders to resistance training-induced muscle hypertrophy.

The aim of this study was to investigate whether baseline values and acute and chronic changes in androgen receptors (AR) markers, including total AR, cytoplasmic (cAR), and nuclear (nAR) fractions, as well as DNA-binding activity (AR-DNA), are involved in muscle hypertrophy responsiveness by comparing young nonresponder and responder individuals. After 10 wk of resistance training (RT), participants were identified as nonresponders using two typical errors (TE) obtained through two muscle cross-sectional area (mCSA) ultrasound measurements (2 × TE; 4.94%), and the highest responders within our sample were numerically matched.

Utilization of Telemedicine to Supervise Medical Students in the Post-Acute/Long-Term Care Setting.

Objectives: Telemedicine has become a widely accepted alternative to face-to-face patient encounters. Although there have been several peer-reviewed journal articles on incorporating telemedicine into the medical school curriculum, particularly during the COVID-19 pandemic, assessments of the effectiveness of remote supervision of medical students have not been reported. This prospective cohort study of student subjects using observational survey data evaluated the efficacy of telemedicine as an educational resource by comparing learning outcomes between osteopathic medical students receiving direct (physically present) supervision with a group who received remote (telemedicine) supervision by clinical faculty within a post-acute/long-term care (PA/LTC) setting.
