The kinetics of aqueous thiolated arsenic oxidation.

Thiolated arsenic (As) compounds have been identified in various natural and engineered environments worldwide and are important for the biogeochemical cycling of As, yet quantitative data regarding their stability and transformation rates remains scarce. This study investigates the oxidation kinetics of mono-, di-, and tri-thioarsenate at varying pH, Fe, and (thio-)As concentrations in the aqueous phase. Experiments conducted over four weeks revealed that all thioarsenates were oxidized faster at lower pH, with rates of up to several μmoles/L/d at a pH of 3.

Comparative Effectiveness of Calcium-Channel Blockers, Angiotensin-Converting Enzyme/Angiotensin Receptor Blockers and Diuretics on Cardiovascular Events Likelihood in Hypertensive African-American and Non-Hispanic Caucasians: A Retrospective Study Across HCA Healthcare.

Background: Hypertension, a leading global risk factor for mortality and disability, disproportionately affects racial and ethnic minorities. Our study investigates the association between the type of prior antihypertensive medication use and the likelihood of cardiovascular events (CVE) and assesses whether the patient's race influences this relationship.

Methods: A retrospective study of 14 836 hypertension cases aged ≥ 40 years was conducted using data from HCA Healthcare between 2017 and 2023.

Use of 3D Printing Technology to Improve Lead Shield Fabrication for Electron Therapy of the Face.

Superficial lesions of the face are often treated with an electron beam and surface collimation utilizing a conformal lead shield with an opening around the region of treatment (ROT). To fabricate the lead shield, an imprint of the patient face is needed. Historically, this was achieved using a laborious and time-consuming process that involved a gypsum imprinted model (GIM) of the patient topography.

Augmenting trauma-focused cognitive behavior therapy for post-traumatic stress disorder with memory specificity training: a randomized controlled trial.

Although trauma-focused cognitive behavior therapy (TF-CBT) is the recommended treatment for post-traumatic stress disorder (PTSD), up to one-half of patients do not respond to this intervention. There is an urgent need to develop new strategies to improve treatment response. Training people to recall specific positive memories may augment treatment gains in TF-CBT.

Systematic Evaluation of IMU Sensors for Application in Smart Glove System for Remote Monitoring of Hand Differences.

Human hands have over 20 degrees of freedom, enabled by a complex system of bones, muscles, and joints. Hand differences can significantly impair dexterity and independence in daily activities. Accurate assessment of hand function, particularly digit movement, is vital for effective intervention and rehabilitation.
