Geometry‐Based Neural‐Network Prediction of Electron Localization Function Topology in Dense Hydrogen

open access: yesChemistry – A European Journal, EarlyView.
We present a machine‐learning framework that predicts the electron localization function (ELF) of dense hydrogen directly from atomic geometry, bypassing explicit electronic‐structure calculations. Trained on ab initio data for fluid hydrogen across multiple pressures, the model achieves high accuracy and reveals pressure‐dependent nonlocal ...

Assessment of Attainable Distances in Proteins by Through‐Space 19F–19F Couplings

open access: yesChemistry – A European Journal, EarlyView.
De novo synthesized difluorinated tryptophan analogues are site‐specifically incorporated into Cyclophilin A (CypA). 19F–19F NOESY build‐up experiments are recorded for each labeled protein, and the distances derived from cross‐relaxation rates are compared to reference distances.

Androgenic Activity of C21 Steroids.

open access: yesExperimental Biology and Medicine, 1950
SummaryΔ16-Dehydroprogesterone exhibited androgenic activity by direct application to the chick's comb. This steroid has approximately 6% of the activity of androsterone. Δ4-Pregnenetriol-17(α),20(β), 21-one-3-diacetate-20,21, and Δ4-Pregenenediol-17 (α), 21-dione-3,20-acetate-21 (compound “S” acetate, Resichstein) inhibited the growth of the ...

N‐Sulfonyl Azalevoglucosan: A Versatile Platform for the Synthesis of Polysubstituted Piperidines

open access: yesChemistry – A European Journal, EarlyView.
Gain by strain: The synthesis of a levoglucosan analog, in which the pyranose oxygen has been replaced by a nitrogen, allows navigation on the piperidine ring to iteratively install functional groups at C1, C2, C3, C4, and C6 positions using simple experimental protocols with minimal protecting group manipulation.

Renoprotective effects of compound 21 and empagliflozin in L-Name-induced hypertensive rats

open access: yesBMC Urology
Background This study investigated the renoprotective effects of compound 21 (C21) and empagliflozin (EMPA) individually and in combination in an Nω-Nitro-L-arginine methyl ester (L-NAME)-induced hypertensive rat model. The objective of this study was to

Reduction Process of Pt(IV) Complexes With Axial Acetato Ligands by Ascorbic Acid; Comparison of Experimental and Computational Tools

open access: yesChemistry – A European Journal, EarlyView.
Comparison of experimental and calculated rate constants for reduction of selected Pt(IV) complexes by ascorbic acid (AA) in water solution at pH = 7. ABSTRACT In the present work, the reduction mechanism of several Pt(IV) complexes bearing two axial acetato ligands by ascorbic acid (AA) was investigated.

Occurrence of severe slugging in oil production lines and mitigation methods: A numerical simulation approach using ALFAsim®

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Severe slugging represents a major challenge in offshore production systems, potentially compromising operational stability and the integrity of installations. Although established simulators such as OLGA® are widely used for its analysis, there is a gap in the literature regarding the application of the one‐dimensional simulator ALFAsim® for ...

Clinical Significance of Acute Kidney Injury in Idiosyncratic Drug‐Induced Liver Injury: A Multicentric Propensity Scores Matched Study

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Clinical significance of acute kidney injury in idiosyncratic drug‐induced liver injury: a multicentric propensity scores matched study. Evidence about the role of acute kidney injury (AKI) in idiosyncratic drug‐induced liver injury (DILI) is still scarce.

Internationalising the teacher education curriculum: An analysis of syllabi and student experiences

open access: yesThe Curriculum Journal, EarlyView.
Abstract Internationalisation has increasingly become a key dimension of quality in initial teacher education (ITE) programmes. Although it is recognised as a means to strengthen future teachers' competencies and expand their professional knowledge, it remains underdeveloped in practice.
