Introduction: Vertical rectus abdominis myocutaneous (VRAM) flap is the most common option for large sacral defect reconstruction but is known to have donor-site abdominal morbidity compared to deep inferior epigastric perforator (DIEP) flaps.

Report: Fifty-seven and 63 year-old men were admitted for large sacral soft tissue defects after tumour excisions. They both underwent an inferiorly based pedicled vertical DIEP flap passed transabdominally with successful postoperative outcomes and not any abdominal wall complication.

Enhanced mechanical properties and in vitro bioactivity of silicon nitride ceramics with SiO, YO, and AlO as sintering aids.

J Mech Behav Biomed Mater

January 2025

School of Materials Science and Engineering, University of Jinan, Jinan, 250022, China. Electronic address:

Silicon nitride (Si₃N₄) ceramics exhibit excellent mechanical properties and biocompatibility, making them highly suitable for biomedical applications, particularly in implants. In this study, the mechanical properties and bioactivity of Si₃N₄ ceramics with varying amounts of Y₂O₃-Al₂O₃-SiO₂ sintering aids were investigated. Increasing the sintering additive content from 4 wt% to 8 wt% substantially improved the bulk density of the ceramics, leading to notable enhancements in mechanical properties.

The non-enzymatic electrochemical detection of glucose by direct oxidation using electrodes modified with suitable electrocatalysts is now well-established. However, it most often requires highly alkaline media, limiting dramatically the use of such electrodes at neutral pH. This is notably the case of Ni-based electrodes.

Understanding complex volcanic hydrosystems using a multi-tracer approach.

Sci Total Environ

January 2025

CNRS, SIGMA Clermont, Institut de Chimie de Clermont-Ferrand, Université Clermont Auvergne, F-63000 Clermont-Ferrand, France.

Climate change affects groundwater availability and residence times, necessitating a thorough understanding of aquifer characteristics to define sustainable yields, particularly in regions where water is heavily exploited. This study focuses on the Volvic volcanic aquifer (Chaîne des Puys, France), where groundwater recharge has decreased due to climate change, raising concerns about water use sustainability. To address these challenges, this work proposes a multi-tracer approach, based on hydrogeological monitoring, including the estimation of groundwater ages, major elements chemistry and water stable isotopes to better characterise this resource decrease and more peculiarly its origin and its impact on the environment that has never been addressed.

Coastal lagoons are diverse habitats with significant ecological gradients, which provide crucial ecosystem services but face threats from human activities such as invasive species and pollution. Among the species inhabiting the lagoons, the critically endangered European eel (Anguilla anguilla) is an emblematic species strongly impacted by contamination and parasitism. Several indicators were developed to assess the quality of eel at a large geographic scale.

Support Care Cancer

January 2025

Supportive and Palliative Care Service, Strasbourg University Hospital, Strasbourg Translational Medicine Federation (FMTS), Université de Strasbourg, Strasbourg, France.

Purpose: Sleep quality contributes to the improvement of quality of life in cancer patients. However, sleep disturbances, of variable and heterogeneous etiologies, are common and frequently overlooked in lung cancer patients. The present study undertakes a rapid review of available peer-reviewed literature on sleep quality in lung cancer patients, specifically non-small-cell lung cancer patients.

Study Objectives: Both the (ICSD) and the sleep-wake disorders section of the (DSM) emphasize the importance of clinical judgment in distinguishing the normal from the pathological in sleep medicine. The fourth edition of the DSM (DSM-IV, 1994) introduced the clinical significance criterion (CSC) to standardize this judgment and enhance diagnostic reliability.

Methods: This review conducts a theoretical and historical content analysis of CSC presence, frequency, and formulation in the diagnostic criteria of sleep disorders.

Carbohydrate-active enzymes (CAZymes) involved in the degradation of plant cell walls and/or the assimilation of plant carbohydrates for energy uptake are widely distributed in microorganisms. In contrast, they are less frequent in animals, although there are exceptions, including examples of CAZymes acquired by horizontal gene transfer (HGT) from bacteria or fungi in several of phytophagous arthropods and plant-parasitic nematodes. Although the whitefly Bemisia tabaci is a major agricultural pest, knowledge of HGT-acquired CAZymes in this phloem-feeding insect of the Hemiptera order (subfamily Aleyrodinae) is still lacking.

Exploration of the Role of Cyclophilins in Established Hepatitis B and C Infections.

Viruses

December 2024

INSERM U1052, CNRS UMR5286, Université Claude Bernard Lyon 1, Hospices Civils de Lyon, Lyon Hepatology Institute (IHU Everest), 69003 Lyon, France.

Cyclophilin (Cyp) inhibitors are of clinical interest in respect to their antiviral activities in the context of many viral infections including chronic hepatitis B and C. Cyps are a group of enzymes with peptidyl-prolyl isomerase activity (PPIase), known to be required for replication of diverse viruses including hepatitis B and C viruses (HBV and HCV). Amongst the Cyp family, the molecular mechanisms underlying the antiviral effects of CypA have been investigated in detail, but potential roles of other Cyps are less well studied in the context of viral hepatitis.

A Guinea Pig Model of Pediatric Metabolic Dysfunction-Associated Steatohepatitis: Poor Vitamin C Status May Advance Disease.

Nutrients

January 2025

Section of Preclinical Disease Biology, Department of Veterinary and Animal Sciences, Faculty of Health and Medical Sciences, University of Copenhagen, 1870 Frederiksberg, Denmark.

Children and teenagers display a distinct metabolic dysfunction-associated steatohepatitis (MASH) phenotype, yet studies of childhood MASH are scarce and validated animal models lacking, limiting the development of treatments. Poor vitamin C (VitC) status may affect MASH progression and often co-occurs with high-fat diets and related metabolic imbalances. As a regulator of DNA methylation, poor VitC status may further contribute to MASH by regulating gene expression This study investigated guinea pigs-a species that, like humans, depends on vitC in the diet-as a model of pediatric MASH, examining the effects of poor VitC status on MASH hallmarks and global DNA methylation levels.

Minimizing Delay and Power Consumption at the Edge.

Sensors (Basel)

January 2025

Institute of Theoretical & Applied Informatics, Polish Academy of Sciences (IITiS-PAN), 44-100 Gliwice, Poland.

Edge computing systems must offer low latency at low cost and low power consumption for sensors and other applications, including the IoT, smart vehicles, smart homes, and 6G. Thus, substantial research has been conducted to identify optimum task allocation schemes in this context using non-linear optimization, machine learning, and market-based algorithms. Prior work has mainly focused on two methodologies: (i) formulating non-linear optimizations that lead to NP-hard problems, which are processed via heuristics, and (ii) using AI-based formulations, such as reinforcement learning, that are then tested with simulations.
