A compilation of global bio-optical in situ data for ocean-colour satellite applications – version four

Abstract. A global in situ dataset for validation of satellite products from the ESA Ocean Colour Climate Change Initiative (OC-CCI) is presented. This version of the compilation, with data starting in 1996, extends to 2025, which is important for the validation of recent algorit...

Proteo‐Metabolomic Profiling of PMM2 ‐ CDG Reveals Dysregulation of Retinoic Acid Synthesis, Myo ‐Inositol, and the Hexosamine Pathway

ABSTRACT Phosphomannomutase deficiency (PMM2‐CDG), the most common congenital disorder of glycosylation (CDG), is characterized by multisystem involvement and a lack of disease‐modifying therapies. While previous transcriptomic studies have uncovered disrupted cellular pathways,...

LaMn1−xNixO3 Perovskite Deposited on γ-Al2O3 Spheres as Catalyst for Dry Reforming of Methane

Dry reforming of methane (DRM) represents a promising route for the valorization of CO2 captured from industrial emissions through high-temperature catalytic conversion. In this work, a LaMn1−xNixO3 perovskite catalyst (x = 0.25, 6 wt% Ni) was synthesized as a powder by solution...

Experimental determination of the lidar ratio for cirrus and polar stratospheric clouds at Dome C, Antarctica, using a Young inversion

Abstract. We present 3 years (2022–2024) of polarisation lidar observations of polar stratospheric clouds (PSCs) and tropospheric cirrus above Concordia Station (Dome C, Antarctica). Layer-mean lidar ratios (LR) at 532 nm are retrieved using the Young inversion method applied to...

Expiratory phase lung mechanics in late-onset Pompe disease: a multicenter study using oscillometry to identify specific breathing abnormalities

Abstract Introduction In late-onset Pompe disease (LOPD), muscle weakness causes restrictive lung impairment. In murine models, glycogen deposition in lung parenchyma suggests additional causes for restriction that remain poorly understood. We investigated whether oscillometry de...

Ferdinandea Island and Graham Bank, Sicily Channel: An Integrated Historical, Geological and Geomorphological Synthesis of a Shallow Submarine Monogenetic Volcanic Field

Ferdinandea Island, part of a shallow-water submarine volcanic field, emerged in the Sicily Channel between Italy and Tunisia in July 1831 and was eroded below sea level within months; its submerged remnant forms the shallowest water depth region of Graham Bank. Here, we review n...

Does an Unconventional Source with a High Silica Content (Obsidian) or a High Alumina Content (Bauxite) Affect the Type of Potassium Zeolite Formation? Preliminary Data on Synthetic Products’ Efficiency in Ammonium Removal

In this paper, obsidian (OS) and bauxite (BX) are used to synthesize zeolites via KOH prefusion, followed by a conventional hydrothermal process (HY) or an unconventional vapor-phase crystallization method (VPC) at 90 °C. The results indicate that, due to their chemical and miner...

A Bioinformatics Analysis Based on Omics and Clinical Data for Graph-Based Patient Stratification in Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is one of the most frequent and lethal malignancies worldwide, with substantial molecular and clinical heterogeneity that complicates prognostic assessment. We aimed to identify molecular subgroups with distinct prognostic profiles using a graph-bas...

α ‐Hydroxybutyrate Association With Incident Type 2 Diabetes Over 10 Years Across Different Glycemic States

ABSTRACT Aim To investigate the association between baseline plasma α‐hydroxybutyrate (α‐HB), an organic acid derived from aminoacid catabolism and glutathione anabolism, and the 10‐year incidence of Type 2 diabetes (T2DM). Materials and Methods This prospective study analysed 13...
