Long-term impact of acute knee injury with hemarthrosis : Osteoarthritis incidence and patient-reported outcomes in a large consecutive cohort over 12 years

Objective: To estimate the 12-year risk of radiographic and/or symptomatic knee osteoarthritis following different MRI-confirmed soft-tissue knee injuries. Design: Prospective cohort study including 814 (70 ​%) of 1129 consecutive patients after acute knee trauma with hemarthrosis in a single hospital. Injuries were classified by sub-acute knee MRI. Follow-up comprised bilateral knee radiography a

Comparative life cycle assessment of perennial and annual crop production : impact of farming systems and management practices

The Intermediate Wheatgrass (IWG) Thinopyrum intermedium (Host) Barkworth & D.R. Dewey, marketed under the trade name Kernza® has been tested in France with a group of farmers since 2017. The Life Cycle Assessment (LCA) is a recognized methodology to assess the potential environmental impacts and resources consumption associated with a production system. An attributional LCA following ISO 1404

Winters restrict a climate change–driven butterfly range expansion despite rapid evolution of seasonal timing traits

Climate change pushes species toward higher latitudes and altitudes, but the proximate drivers of range expansions vary, and it is unclear whether evolution facilitates climate change–induced range changes. In a temporally replicated field experiment, we trans-located wall brown butterflies (Lasiommata megera) descending from range interior and range margin populations to sites at 1) the range int

CLIP2 : a novel functional player in AQP5 trafficking dynamics and implications for Sjögren’s disease

Background: Sjögren’s disease (SjD) is an autoimmune condition affecting exocrine glands, resulting in decreased saliva and tear production. Aquaporin 5 (AQP5) is a transmembrane water channel playing a central role in water transport. In SjD, deregulation of AQP5 expression, trafficking and interactions with various proteins contribute to the underlying disease mechanisms. Methods: Co-immunopreci

Influence of Chloride and Electrolyte Stability on Passivation Layer Evolution at the Negative Electrode of Mg Batteries Revealed by operando EQCM-D

Rechargeable magnesium batteries are promising for future energy storage. However, among other challenges, their practical application is hindered by low coulombic efficiencies of magnesium plating and stripping. Fundamental processes such as the formation, structure, and stability of passivation layers and the influence of different electrolyte components on them are still not fully understood. I

Manipulating Horizontal Zn Deposition with Indium Salt Additive for Anode-Free Zn Batteries

Anode-free zinc batteries offer reduced weight and simplified production compared to traditional zinc metal batteries, but challenges such as dendrite formation and parasitic reactions limit their efficiency and cycle life. In this study, we present an effective strategy to form a zincophilic interphase in situ via indium co-deposition during cycling, using InCl3 as an electrolyte additive. Zinc p

Interfacial Chemistry in Aqueous Lithium-Ion Batteries : A Case Study of V2O5 in Dilute Aqueous Electrolytes

Aqueous lithium-ion batteries (ALIBs) are promising for large-scale energy storage systems because of the cost-effective, intrinsically safe, and environmentally friendly properties of aqueous electrolytes. Practical application is however impeded by interfacial side-reactions and the narrow electrochemical stability window (ESW) of aqueous electrolytes. Even though higher electrolyte salt concent

Fully exploited imidazolium bromide for simultaneous resolution of cathode and anode challenges in zinc-bromine batteries

Aqueous zinc-bromine (Zn-Br2) batteries feature operational safety and high-energy and high-power densities, but suffer from polybromide dissolution in the cathode and the low reversibility of Zn metal in the anode. Here, we demonstrate that these challenges can be simultaneously tackled by using a fully exploited imidazolium bromide (MPIBr). An in-depth analysis demonstrates that MPIBr enhances b

An interweaving 3D ion-conductive network binder for high-loading and lean-electrolyte lithium-sulfur batteries

The binder plays a crucial role in maintaining the integrity and enhancing the conductivity of the electrode, although it accounts for a small weight fraction in the entire electrode. However, the conventional binder used in lithium-sulfur (Li-S) batteries fails to effectively tackle the challenges posed by the shuttle effect of lithium polysulfides, as well as the issues of poor conductivity and

Anabolic indices of matrix proteins identify regenerative small RNA intrinsic to human cartilage

Some vertebrates regenerate appendages through the action of small noncoding RNAs (smRNAs) expressed in their blastema. Inspired by these models, we investigated whether similar smRNA-mediated mechanisms might contribute to the intrinsic repair capacity of human cartilage. Although humans lack the capacity to regenerate entire limbs, digit tip regrowth and joint cartilage repair following joint di

Clinical Performance of the Elecsys CSF pTau181/Aβ42 Ratio for Concordance with Tau-PET in Two Independent Cohorts

Introduction: Amyloid- and tau-positron emission tomography (PET) are promising modalities for detecting pathological changes associated with Alzheimer’s disease (AD); however, their application is limited. Although the use of cerebrospinal fluid (CSF) biomarkers as alternatives to amyloid-PET and tau-PET has been explored, no in vitro diagnostic-approved or commercial CSF biomarker assays are cur

Revealing the degradation pathways of layered Li-rich oxide cathodes

Layered lithium-rich transition metal oxides are promising cathode candidates for high-energy-density lithium batteries due to the redox contributions from transition metal cations and oxygen anions. However, their practical application is hindered by gradual capacity fading and voltage decay. Although oxygen loss and phase transformation are recognized as primary factors, the structural deteriora

Socio-geographical disparities in cardiometabolic multimorbidity in Sweden : an Intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (I-MAIHDA)

Background: Mapping social and geographical disparities in health outcomes helps to identify vulnerable groups that should be targeted for intervention. This study aims to assess the disparities in cardiometabolic multimorbidity, the presence of at least two cardiometabolic diseases (CMD), including type 2 diabetes, heart disease, and stroke, among middle-aged adults across socio-geographical inte

Neurocognition, cerebellar functions and psychiatric features in spinocerebellar ataxia type 34: a case series

Objective: This study primarily aimed to comprehensively characterize the neurological, neuroradiological and neurocognitive profiles, as well psychiatric features of individuals with Spinocerebellar Ataxia Type 34 (SCA34) associated with pathogenic variants in the ELOVL4 gene. Secondarily, we investigated the relationship between neurocognitive functions and cerebellar morphology in individuals w

Characterising PRPF31-associated retinal dystrophy : Clinical insights from baseline data in a natural history study

Purpose: To characterise the baseline clinical features and genotypes of adults with pre-mRNA processing factor 31 (PRPF31)-associated retinal dystrophy (RD) enrolled in a prospective, multicentre 4-year natural history study, and to explore correlations between selected baseline parameters.

Analysis of high flux membranes for desalination in waste-heat driven vacuum membrane distillation plants : Experimental validation and techno-economic analysis

Vacuum membrane distillation is a promising technology for seawater desalination, as it enables high recovery ratios, with reasonable thermal and minimal electric consumption. Ceramic membranes can offer notable advantages over polymeric membranes, mainly due to their robust thermal and mechanical stability, yet they have limited representation in the literature. Accordingly, this work investigate

How overdischarge destabilizes NCM cathodes : A combined study on structural evolution and chemical states

Overdischarge poses severe challenges to the structural integrity and electrochemical performance of layered LiNixCoyMn1-x-yO2 (NCM) cathodes in lithium-ion batteries, yet the underlying degradation mechanisms remain insufficiently understood. Through a combined experimental and theoretical approach, this study systematically investigates how overdischarge destabilizes NCM cathodes with varying tr
