In this paper, microporous Zn-based zeolitic imidazolate framework with the sodalite cage structure (SOD-ZIF-8) was synthesized by the solvothermal method. Powder X-ray diffraction (PXRD), scanning electron microscopy (SEM) and N2 adsorption were employed to characterize the synthesized material. An ultra-sensitive electrochemical sensor based on highly dispersed bimetallic Ni-Pt nanoparticles immobilized on zeolitic metal-organic framework ZIF-8 for dopamine quantification is introduced for the first time.

Coronary revascularisation deferral based on quantitative flow ratio or fractional flow reserve: a post hoc analysis of the FAVOR III Europe trial.

EuroIntervention

January 2025

Hospital Clínico San Carlos IDISSC, Complutense University of Madrid, Madrid, Spain and Centro de Investigación Biomédica en Red - Enfermedades Cardiovasculares (CIBERCV), Instituto de Salud Carlos III, Madrid, Spain.

Background: Safe deferral of revascularisation is a key aspect of physiology-guided percutaneous coronary intervention (PCI). While recent evidence gathered in the FAVOR III Europe trial showed that quantitative flow ratio (QFR) guidance did not meet non-inferiority to fractional flow reserve (FFR) guidance, it remains unknown if QFR might have a specific value in revascularisation deferral.

Aims: We aimed to evaluate the safety of coronary revascularisation deferral based on QFR as compared with FFR.

January 2025

Department of Anesthesiology, Critical Care and Burn Unit, University Saint-Louis-Lariboisière Hospital, AP-HP, Paris, France; Université de Paris Cité, Paris, France; INSERM UMR-S 942, Cardiovascular Markers in Stress Condition (MASCOT), Université de Paris Cité, Paris, France; Fédération Hopsitalo-Universitaire (FHU) Precision Medicine for a Comprehensive Care of Critically ill patients, Université de Paris Cité, Paris, France; Cardiovascular and Renal Clinical Trialists, Nancy, France.

With an ageing world population and increasing prevalence, heart failure is increasingly frequent as a comorbidity in operative patients, and its accurate preoperative diagnosis is essential to improve postoperative prognosis in patients undergoing noncardiac surgery. Use of electronic health records to assist in the accuracy of diagnosis and definition of an adjudicated heart failure reference standard could help guide intraoperative practice and improve outcomes in patients with heart failure.

Background: The global mpox outbreak which started in May 2022 was caused by a novel clade IIb variant of the mpox virus (MPXV). It differed from the traditional Western and Central Africa disease in transmission patterns and clinical presentation.

Methods: To address the need for detailed clinical and virologic data, we conducted an observational cohort study (MOSAIC) during May 2022-July 2023 in individuals with confirmed MPXV infection enrolled in six European Countries.

Background: In older people, medications with anticholinergic or sedative properties are associated with falls, frailty, and functional and cognitive impairment. These medications are often described as a subset of potentially inappropriate medications (PIMs). We examined the prevalence of anticholinergic or sedative medications to avoid in older people in France in 2023.

This work explores two methods to encapsulate Thymoquinone (TQ) into lipid nanocapsules (LNCs) for oral administration. TQ was added during the phase inversion temperature method (TQ-LNCs-1) or to unload LNCs dispersion (TQ-LNCs-2). LNCs were evaluated for mean diameter, polydispersity index (PDI), ζ-potential, drug loading (DL), drop tensiometer, storage stability, stability in simulated gastrointestinal fluids (SGIF), and intestinal permeability across Caco-2 cells.

Objective: Monoallelic variants in the transient receptor potential melastatin-related type 3 gene (TRPM3) have been associated with neurodevelopmental manifestations, but knowledge on the clinical manifestations and treatment options is limited. We characterized the clinical spectrum, highlighting particularly the epilepsy phenotype, and the effect of treatments.

Methods: We analyzed retrospectively the phenotypes and genotypes of 43 individuals with TRPM3 variants, acquired from GeneMatcher and collaborations (n = 21), and through a systematic literature search (n = 22).

Neo-enhancers in T-cell acute lymphoblastic Leukaemia (T-ALL) and beyond.

Int J Cancer

January 2025

Laboratory of Onco-Hematology, Necker Children's Hospital, Assistance Publique-Hôpitaux de Paris (AP-HP), Paris, France.

T-cell acute lymphoblastic leukaemia (T-ALL) is a rare aggressive haematological malignancy characterised by the clonal expansion of immature T-cell precursors. It accounts for 15% of paediatric and 25% of adult ALL. T-ALL is associated with the overexpression of major transcription factors (TLX1/3, TAL1, HOXA) that drive specific transcriptional programmes and constitute the molecular classifying subgroups of T-ALL.

Helical foldamers constitute particularly relevant targets in the field of host-guest chemistry, be that as hosts or substrates. In this context, the strategies reported so far to control the dimensions and shape of foldamers mainly involve modifications of the skeleton through covalent synthesis. Herein, we prepared an oligopyridine dicarboxamide foldamer substituted by photo-active tetraphenylethylenes (TPE).

Mechanochemical Deracemization: A Sustainable Approach to Enantiopurity.

Chemistry

January 2025

Universite Catholique de Louvain, IMCN / MOST, 1 Place Louis Pasteur, Batîment Lavoisier, b.172, 1348, Louvain-La-Neuve, BELGIUM.

We introduce mechanochemical deracemization (MCDR) as a novel strategy for obtaining enantiopure compounds. This study demonstrates the successful transposition of six archetypical deracemization reactions from a solvent-based to a solvent-minimized ball milling environment. The scope includes a ketone, isoindolinones, imines, an ester, and an inorganic compound, all of which deracemized successfully.

Laboratoire Clostridioides difficile associé au Centre National de Référence des bactéries anaérobies et du botulisme, Hôpital Saint-Antoine, Assistance Publique Hôpitaux de Paris, 184 rue du Faubourg Saint-Antoine, 75012 Paris France, UMR-S 1139 3PHM, Université Paris Cité, Paris, France.

Clostridioides difficile is a Gram-positive, spore-forming anaerobic enteropathogen responsible for a wide spectrum of clinical diseases ranging from mild diarrhoea to pseudomembranous colitis. It is the first cause of healthcare-associated diarrhoeas, but community-associated Clostridioides difficile infections (CDI) are increasingly reported in patients without the common risk factors (age > 65 years, previous antibiotic treatment). The main C.

While the latest WHO classification of hematological neoplasms helps refine the diagnostic criteria for anaplastic large cell lymphomas (ALCL), their diagnosis can still be challenging. This retrospective series of 10 ALCL cases illustrates the cytological appearance and immunological profile obtained through flow cytometry (FCM) from various sample types, including lymph node biopsies (LN), peripheral blood (PB), cerebrospinal fluid (CSF), and pleural fluid (PF). ALCL exhibits a polymorphic cytological appearance, ranging from "doughnut" cells to Hodgkin-like cells, very large cells, and small cells, with this polymorphism being particularly pronounced in ALK (-) forms.

Three-quarters of the planet's land surface has been altered by humans, with consequences for animal ecology, movements and related ecosystem functioning. Species often occupy wide geographical ranges with contrasting human disturbance and environmental conditions, yet, limited data availability across species' ranges has constrained our understanding of how human pressure and resource availability jointly shape intraspecific variation of animal space use. Leveraging a unique dataset of 758 annual GPS movement trajectories from 375 brown bears (Ursus arctos) across the species' range in Europe, we investigated the effects of human pressure (i.
