Blocking the voltage‐gated sodium channel hNav1.5 as a novel pH‐dependent mechanism of action for tamoxifen

FEBS Open Bio, EarlyView.
Patch‐clamp recordings revealed that tamoxifen inhibits voltage‐gated sodium channels, especially under acidic conditions, both common in metastatic cancer cells. These effects may explain certain antitumor properties of tamoxifen, highlighting a novel mechanism of action beyond its known endocrine effects.

Quantitative Iron Measurements in the Basal Ganglia of NBIA Patients Using QSM: Insights From a Tertiary Center

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurodegeneration with brain iron accumulation (NBIA) comprises rare genetic disorders characterized by predominantly extrapyramidal symptoms and iron deposition in the basal ganglia. Conventional magnetic resonance imaging (MRI) detects qualitative changes but cannot accurately quantify iron accumulation. Quantitative susceptibility

Local anesthetics and their adjuncts [PDF]

Pediatric Anesthesia, 2011
SummaryLocal anesthetics (LA) block propagation of impulses along nerve fibers by inactivation of voltage‐gated sodium channels, which initiate action potentials (1). They act on the cytosolic side of phospholipid membranes. Two main chemical compounds are used, amino esters and amino amides. Amino esters are degraded by pseudocholinesterases in plasma.

Interaction of Local Anesthetics with Biomembranes Consisting of Phospholipids and Cholesterol: Mechanistic and Clinical Implications for Anesthetic and Cardiotoxic Effects

Anesthesiology Research and Practice, 2013
Despite a long history in medical and dental application, the molecular mechanism and precise site of action are still arguable for local anesthetics. Their effects are considered to be induced by acting on functional proteins, on membrane lipids, or on ...

Association of Higher Levels of High‐Sensitivity C‐Reactive Protein With Future Development of Psoriatic Arthritis in Psoriasis: A Prospective Cohort Study

Arthritis Care &Research, EarlyView.
Objective We aimed to assess whether high‐sensitivity C‐reactive protein (hsCRP) levels could predict the development of psoriatic arthritis (PsA) in patients with psoriasis. Methods We analyzed data from a prospective cohort of patients with psoriasis without PsA at enrollment.

Avaliação da Densidade dos anestésicos locais e da combinação com adjuvantes: estudo em laboratório Evaluación de la densidad de los anestésicos locales y de la combinación con adyuvantes: estudio en laboratorio Assessment of the densities of local anesthetics and their combination with adjuvants: an experimental study

Revista Brasileira de Anestesiologia, 2009
JUSTIFICATIVA E OBJETIVOS: Uma das mais importantes propriedades físicas que afetam o nível da analgesia obtida após a injeção subaracnoidea de um anestésico local é sua densidade relativa à densidade do líquido cefalorraquidiano (LCR) a 37°C. O objetivo

Moderators and Mediators of Pain and Function Outcomes in a New Service Delivery Model for Management of Knee Osteoarthritis in Primary Care: Secondary Exploratory Analysis of a Randomized Controlled Trial

Arthritis Care &Research, EarlyView.
Objective Our objective was to explore moderators and mediators influenced changes in pain and function in people with knee osteoarthritis (OA) receiving a new model of primary care service delivery (Optimizing Primary Care Management of Knee Osteoarthritis [PARTNER]), at 12 months (ACTRN: 12617001595303).

Screening for Social Determinants of Health in Patients With Systemic Lupus Erythematosus: A Point‐of‐Care Feasibility Study

Arthritis Care &Research, EarlyView.
Objective Social determinants of health (SDoH) can impact outcomes but are not routinely screened for in US outpatient rheumatology clinics. This study determined the feasibility of routine point‐of‐care SDoH screening among patients with systemic lupus erythematosus (SLE) and associated barriers and facilitators at the physician, care team, and ...
