Evaporation-Assisted Synthesis of Olympic Gels.

Angew Chem Int Ed Engl

January 2025

UESTC: University of Electronic Science and Technology of China, Institute of Fundamental and Frontier Sciences, Jianshe Road, Chengdu, CHINA.

Catenated networks exclusively composed of intertwining rings were first envisioned as "Olympic gels" by Pierre-Gilles de Gennes four decades ago but have not been successfully prepared in artificial materials yet due to the challenge in synthesis. Herein, we present a bio-inspired, evaporation-assisted strategy to address this issue. In our design, the evaporation of liquid catalysts that induce ring-chain equilibrium of polymer systems drives macrocycles to encounter and assists their catenation through reversible cyclization.

CD36 enrichment in HER2-positive mesenchymal stem cells drives therapy refractoriness in breast cancer.

J Exp Clin Cancer Res

January 2025

Microenvironment and Biomarkers of Solid Tumors Unit, Department of Experimental Oncology, Amadeolab Fondazione IRCCS Istituto Nazionale Dei Tumori Di Milano, Milan, Italy.

Background: Growing evidence shows that the reprogramming of fatty acid (FA) metabolism plays a key role in HER2-positive (HER2 +) breast cancer (BC) aggressiveness, therapy resistance and cancer stemness. In particular, HER2 + BC has been defined as a "lipogenic disease" due to the functional and bi-directional crosstalk occurring between HER2-mediated oncogenic signaling and FA biosynthesis via FA synthase activity. In this context, the functional role exerted by the reprogramming of CD36-mediated FA uptake in HER2 + BC poor prognosis and therapy resistance remains unclear.

January 2025

Patient-Reported Outcomes Research (PROQOL), Health Economics Clinical Trial Unit (URC-ECO), Hotel-Dieu Hospital, AP- HP, Paris, France.

Background: The COVID-19 pandemic has severely affected vulnerable populations, especially individuals living with HIV/AIDS (PLWHA). The convergence of HIV/AIDS and COVID-19 presents unique challenges, exacerbating existing health concerns and magnifying the strain on individuals already grappling with compromised immune systems. This study aimed to investigate the mental well-being repercussions faced by PLWHA co-infected with SARS-CoV-2 in France.

Aim: To describe the effects of Glucagon-like peptide-1 receptor agonists (GLP-1RA) in patients with familial partial lipodystrophy (FPLD) assessed in a real-life setting in a national reference network.

Patients And Methods: We retrospectively collected clinical and metabolic parameters in patients with FPLD in the French lipodystrophy reference network, who initiated GLP-1RA. Data were recorded before, at one-year (12 ± 6 months) and at the latest follow-up on GLP-1RA therapy (≥18 months).

The objective of this study was to evaluate the effect of seletracetam (SEL), a potent modulator of synaptic vesicle glycoprotein 2A (SV2A), in patients with photoparoxysmal EEG response (PPR) to intermittent photic stimulation (IPS) as proof-of-principle of efficacy in patients with epilepsy. In this multicenter, single-blind Phase II study, adults with photosensitive epilepsy, with/without concomitant antiseizure medication therapy, underwent IPS under 3 eye conditions (at eye closure, eyes closed and eyes open) after a single oral dose of placebo (day - 1) or SEL (day 1; 0.5, 1, 2, 4, 10, or 20 mg).

Female genital mutilation: the current situation and the role of healthcare workers in combating excision. Female genital mutilation/cutting (FGM/C) affects more than 200 million girls and women, mainly in African countries. These procedures have no medical rationale and are essentially a form of power abuse.

Biomethane production from biological methanation of CO is promising both for biogas upgrading and surplus renewable energy storage. One of the questions for process upscaling is the impact of oxygen (in the biogas or in the purified CO-rich off-gas) on the biological process. An adapted anaerobic thermophilic consortium was submitted to increasing amounts of oxygen in batch and continuous tests at partial pressures ranging from 0 to 50 mbar.

Tumour DNA methylation markers associated with breast cancer survival: a replication study.

Breast Cancer Res

January 2025

Precision Medicine, School of Clinical Sciences at Monash Health, Monash University, 246 Clayton Road, Clayton, VIC, 3168, Australia.

Background: Tumour DNA methylation has been investigated as a potential marker for breast cancer survival, but findings often lack replication across studies.

Methods: This study sought to replicate previously reported associations for individual CpG sites and multi-CpG signatures using an Australian sample of 425 women with breast cancer from the Melbourne Collaborative Cohort Study (MCCS). Candidate methylation sites (N = 22) and signatures (N = 3) potentially associated with breast cancer survival were identified from five prior studies that used The Cancer Genome Atlas (TCGA) methylation dataset, which shares key characteristics with the MCCS: comparable sample size, tissue type (formalin-fixed paraffin-embedded; FFPE), technology (Illumina HumanMethylation450 array), and participant characteristics (age, ancestry, and disease subtype and severity).

Constructed wetlands (CWs), originally designed to mitigate chemical water pollution, often host noticeable aquatic fauna. However, little is known about the impact of the contaminants circulating within CWs on this local fauna, questioning the role of CWs as ecological refuges or traps. We aimed to assess the potential of an agricultural CWs in northern France to act as an ecological trap for aquatic fauna and the potential consequences on wetland functioning.

As batteries drive the transition to electrified transportation and energy systems, ensuring their quality, reliability, lifetime, and safety is crucial. While the solid electrolyte interphase (SEI) is known to govern these performance characteristics, its dynamic nature makes understanding its nucleation, growth, and composition an ambitious, yet elusive aspiration. This work employs chalcogenide fibres embedded in negative electrode materials for operando Infra-red Fibre-optic Evanescent Wave Spectroscopy (IR-FEWS), combined with Multivariate Curve Resolution by Alternating Least Squares (MCR-ALS) algorithms for spectra analysis.

Introduction: The introduction of intraoperative fluorophores represented a significant advancement in neurosurgical practice. Nowadays they found different applications: in oncology to improve the visualization of tumoral tissue and optimize resection rates and in vascular neurosurgery to assess the exclusion of vascular malformations or the permeability of bypasses, with real-time intraoperative evaluations.

Research Question: A comprehensive knowledge of how fluorophores work is crucial to maximize their benefits and to incorporate them into daily neurosurgical practice.

Toward alpha-synuclein seed amplification assay in clinical practice.

Alzheimers Dement (Amst)

January 2025

Biochemistry and Molecular Biology Department Neurodegenerative Pathologies LBMMS Hospices Civils de Lyon Lyon France.

Introduction: Seed amplification assays (SAAs) demonstrate remarkable diagnostic performance in alpha-synucleinopathies. However, existing protocols lack accessibility in routine laboratories, mainly due to the requirement for in-house production of recombinant alpha-synuclein (aSyn). This study proposes a cerebrospinal fluid (CSF) aSyn-SAA protocol using solely commercial reagents to facilitate its clinical implementation.
