Improving Understanding of Fexofenadine Pharmacokinetics to Assess Pgp Phenotypic Activity in Older Adult Patients Using Population Pharmacokinetic Modeling.

Clin Pharmacokinet

January 2025

Clinical Pharmacology and Toxicology Service, Anesthesiology, Pharmacology and Intensive Care Department, Geneva University Hospitals, 4 Rue Gabrielle Perret-Gentil, 1205, Geneva, Switzerland.

Background And Objective: Fexofenadine is commonly used as a probe substrate to assess P-glycoprotein (Pgp) activity. While its use in healthy volunteers is well documented, data in older adult and polymorbid patients are lacking. Age- and disease-related physiological changes are expected to affect the pharmacokinetics of fexofenadine.

This paper investigates the use of the BOTDA (Brillouin Optical Time-Domain Analysis) technology to monitor a large-scale bored pile wall in the field. Distributed fiber optic sensors (DFOSs) were deployed to measure internal temperature and strain changes during cement grouting, hardening, and excavation-induced deformation of a secant pile wall. The study details the geological conditions and DFOS installation process.

Background/objectives: Circadian clocks are endogenous systems that regulate numerous biological, physiological, and behavioral events in living organisms. Aging attenuates the precision and robustness of circadian clocks, leading to prolonged and dampened circadian gene oscillation rhythms and amplitudes. This study investigated the effects of food-derived polyphenols such as ellagic acid and its metabolites (urolithin A, B, and C) on the aging clock at the cellular level using senescent human fibroblast cells, TIG-3 cells.

Blood-based extracellular matrix (ECM) fragments have been identified as potential pharmacologic biomarkers in spondyloarthritis and diagnostic biomarkers in psoriatic arthritis and psoriasis vulgaris. This study aimed to explore whether ECM fragments can differentiate patients with psoriasis from healthy controls (HC) and determine their potential as biomarkers for response to treatment in psoriasis. The study population included 59 patients with moderate to severe psoriasis, not receiving systemic anti-psoriatic treatment at inclusion, and 52 HC matched by age, sex, and BMI.

Background And Objectives: Drug development in schizophrenia is limited by the differential scaling of the active treatment and placebo arms of a study, such that, as the number of sites increases, the magnitude of placebo response disproportionately increases. The objective of this article was to identify factors conducive to efficient recruitment as a step towards trial designs allowing recruitment of more participants per site, leading to reduced variability, and potentially a smaller placebo effect.

Patients And Methods: Using the information of 554 individuals, we calculated the percentage of individuals who were screened, consented, and retained in our research, along with rationale for nonconsent.

The simultaneous sequencing of multiple types of biomolecules can facilitate understanding various forms of regulation occurring in cells. Cosequencing of miRNA and mRNA at single-cell resolution is challenging, and to date, only a few such studies (examining a quite limited number of cells) have been reported. Here, we developed a parallel single-cell small RNA and mRNA coprofiling method (PSCSR-seq V2) that enables miRNA and mRNA coexpression analysis in many cells.

Inefficient targeting of muscle stem cells (MuSCs), also called satellite cells, represents a major bottleneck of current therapeutic strategies for muscular dystrophies, as it precludes the possibility of promoting compensatory regeneration. Here we describe a muscle-targeting delivery platform, based on gold nanoparticles, that enables the release of therapeutic oligonucleotides into MuSCs. We demonstrate that AuNPs conjugation to an aptamer against α7/β1 integrin dimers directs either local or systemic delivery of microRNA-206 to MuSCs, thereby promoting muscle regeneration and improving muscle functionality, in a mouse model of Duchenne Muscular Dystrophy.

Predicting cell morphological responses to perturbations using generative modeling.

Nat Commun

January 2025

Department of Computational Health, Institute of Computational Biology, Helmholtz Zentrum München, Munich, Germany.

Advancements in high-throughput screenings enable the exploration of rich phenotypic readouts through high-content microscopy, expediting the development of phenotype-based drug discovery. However, analyzing large and complex high-content imaging screenings remains challenging due to incomplete sampling of perturbations and the presence of technical variations between experiments. To tackle these shortcomings, we present IMage Perturbation Autoencoder (IMPA), a generative style-transfer model predicting morphological changes of perturbations across genetic and chemical interventions.

Targeting N-Myc in neuroblastoma with selective Aurora kinase A degraders.

Cell Chem Biol

January 2025

Department of Medicinal Chemistry, University of Minnesota, Minneapolis, MN 55455, USA; Department of Biochemistry, Molecular Biology, and Biophysics, University of Minnesota, Minneapolis, MN 55455, USA; Department of Chemistry, University of Minnesota, Minneapolis, MN 55455, USA. Electronic address:

The N-Myc transcription factor, encoded by MYCN, is a mechanistically validated, yet challenging, target for neuroblastoma (NB) therapy development. In normal neuronal progenitors, N-Myc undergoes rapid degradation, while, in MYCN-amplified NB cells, Aurora kinase A (Aurora-A) binds to and stabilizes N-Myc, resulting in elevated protein levels. Here, we demonstrate that targeted protein degradation of Aurora-A decreases N-Myc levels.

Gout and Hyperuricemia: A Narrative Review of Their Comorbidities and Clinical Implications.

J Clin Med

December 2024

Department of Rheumatology, Päijät-Häme Central Hospital, Wellbeing Services County of Päijät-Häme, 15850 Lahti, Finland.

Gout is the most common form of inflammatory arthritis, caused by the deposition of monosodium urate crystals in the joints due to elevated serum uric acid levels. Its prevalence and associated healthcare burden have been rising in recent decades, a trend expected to continue. It is crucial to recognize that gout and hyperuricemia are not merely causes of painful joint flares, but systemic metabolic disorders linked to a broad spectrum of comorbidities such as cardiovascular diseases, chronic kidney disease, diabetes, insulin resistance, steatotic liver disease, osteoarthritis, and respiratory and eye diseases.

Article Synopsis
  • The study focuses on patients with rib fractures, a common injury in trauma admissions, and aims to use mobile platforms to monitor their postdischarge pain and mental health through patient-reported outcome measures (PROMs).
  • Among the 72 patients studied, over half experienced moderate to severe pain two weeks after discharge, with higher initial pain levels linked to worse outcomes.
  • Results indicate that while early pain is associated with increased mental health symptoms, patients showed notable improvement in both pain and mental health over the following weeks, underscoring the value of using technology for patient care.
