Supramolecular dyads as photogenerated qubit candidates.

Molecular spin qubits have the advantages of synthetic flexibility and amenability to be tailored to specific applications. Among them, chromophore-radical systems have emerged as appealing qubit candidates. These systems can be initiated by light to form triplet-radical pairs that can result in the formation of quartet states by spin mixing.

The ISC machinery assembles [2Fe-2S] clusters by formation and fusion of [1Fe-1S] precursors.

Iron-sulfur clusters are essential metallocofactors synthesized by multiprotein machineries via an unclear multistep process. Here we report a step-by-step dissection of the [2Fe-2S] cluster assembly process by the Escherichia coli iron-sulfur cluster (ISC) assembly machinery using an in vitro reconstituted system and a combination of biochemical and spectroscopic techniques. We show that this process is initiated by iron binding to the scaffold protein IscU, which triggers persulfide insertion by the cysteine desulfurase IscS upon the formation of a complex with IscU.

A prospective pragmatic evaluation of automatic trial matching tools in a molecular tumor board.

Publicly available trial matching tools can improve the access to therapeutic innovations, but errors may expose to over-solicitation and disappointment. We performed a pragmatic non-interventional prospective evaluation on sequential patients at the Molecular Tumor Board of Centre Leon Berard. During 10 weeks in 2024, we analysed 157 patients with four clinical trial matching tools from the 19 screened: Klineo, ScreenAct, Trialing and DigitalECMT.

The UnconTrust Database for Studies of Unconscious Semantic Processing and Attentional Allocation.

The question of what processes can take place without conscious awareness has generated extensive research. Yet there is still no consensus regarding the extent and scope of unconscious processing, and past research abounds with conflicting results. A possible reason for this lack of consensus is the diversity of methods in the field, as the methodological choices might influence the results.

MCT1 lactate transporter blockade re-invigorates anti-tumor immunity through metabolic rewiring of dendritic cells in melanoma.

Dendritic cells (DC) are key players in antitumor immune responses. Tumors exploit their plasticity to escape immune control; their aberrant surface carbohydrate patterns (e.g.

Short-term evolutionary implications of an introgressed size-determining supergene in a vulnerable population.

The Thorny Skate (Amblyraja radiata) is a vulnerable species displaying a discrete size-polymorphism in the northwest Atlantic Ocean (NWA). We conducted whole genome sequencing of samples collected across its range. Genetic diversity was similar at all sampled sites, but we discovered a ~ 31 megabase bi-allelic supergene associated with the size polymorphism, with the larger size allele having introgressed in the last ~160,000 years B.

Helioseismic inference of the solar radiative opacity.

The Sun is the most studied of all stars, and thus constitutes a benchmark for stellar models. However, our vision of the Sun is still incomplete, as illustrated by the current debate on its chemical composition. The problem reaches far beyond chemical abundances and is intimately linked to microscopic and macroscopic physical ingredients of solar models such as radiative opacity, for which experimental results have been recently measured that still await theoretical explanations.

Sanctuary for vulnerable Arctic species at the Borealis Mud Volcano.

Borealis is a recently discovered submerged mud volcano in the Polar North Atlantic, differing from the numerous methane seepages previously identified in the region. Here we show in situ observations from a remotely operated vehicle (ROV), capturing the release of warm (11.5 °C) Neogene sediments and methane-rich fluids from a gryphon at Borealis.

Double-Barreled Vascularized Fibula Free Flap in Pediatric Tibial Bone Defect Reconstruction: A 20-Year Monocentric Experience.

Introduction: Reconstructing large bone defects for lower limb salvage in the pediatric population remains challenging due to complex oncological or septic issues, limited surgical options, and lengthy procedures prone to complications. The vascularized double-barreled fibula free flap is pivotal for reconstructing large bones. In this article, we report our experience with this technique in the surgical management of pediatric tibial bone defects.

Feasibility study of the digital tool Max for the patient-provided medication list in the medication reconciliation process prior to hospitalisation: patient willingness and usability, time saved and reliability.

Purpose: More than 20% of prescription errors in hospitals are due to an incomplete medication history. Medication reconciliation is a solution to decrease unintentional discrepancies between medications taken at home and hospital prescriptions. It is a normalised clinical activity but it is time consuming.

Return to duty after non-surgical treatment of a non-neurological thoracic or lumbar spine fracture in French military patients: a retrospective analysis of 54 patients.

Introduction: Non-surgical management of non-neurological thoracic or lumbar spine (TL) fractures seems to provide good results in the civilian population, leading to return to work in most cases. However, data on the military population are limited, particularly regarding return to duty. This study aimed to describe a population of French military patients with traumatic non-neurological TL fractures and the outcomes of non-surgical management regarding operational capacity.

Meiosis and retinoic acid in the mouse fetal gonads: An unforeseen twist.

In mammals, differentiation of germ cells is crucial for sexual reproduction, involving complex signaling pathways and environmental cues defined by the somatic cells of the gonads. This review examines the long-standing model positing that all-trans retinoic acid (ATRA) acts as a meiosis-inducing substance (MIS) in the fetal ovary by inducing expression of STRA8 in female germ cells, while CYP26B1 serves as a meiosis-preventing substance (MPS) in the fetal testis by degrading ATRA and preventing STRA8 expression in the male germ cells until postnatal development. Recent genetic studies in the mouse challenge this paradigm, revealing that meiosis initiation in female germ cells can occur independently of ATRA signaling, with key roles played by other intrinsic factors like DAZL and DMRT1, and extrinsic signals such as BMPs and vitamin C.

microbiota model recapitulates and predicts individualised sensitivity to dietary emulsifier.

Background: Non-absorbed dietary emulsifiers, including carboxymethylcellulose (CMC), directly disturb intestinal microbiota, thereby promoting chronic intestinal inflammation in mice. A randomised controlled-feeding study (Functional Research on Emulsifiers in Humans, FRESH) found that CMC also detrimentally impacts intestinal microbiota in some, but not all, healthy individuals.

Objectives: This study aimed to establish an approach for predicting an individual's sensitivity to dietary emulsifiers via their baseline microbiota.

The Autonomic Nervous System and Inflammation in Chronic Kidney Disease.

The autonomic nervous system plays a crucial role in regulating physiological processes and maintaining homeostasis through its two branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system. Dysregulation of the autonomic system, characterized by increased sympathetic activity and reduced parasympathetic tone, is a common feature in chronic kidney disease (CKD) and cardiovascular disease. This imbalance contributes to a pro-inflammatory state, exacerbating disease progression and increasing the risk for cardiovascular events.

Modeling ocular surface ion and water transport by generation of lipid- and mucin-producing human Meibomian gland and conjunctival epithelial cells.

Despite the importance of ocular surface in human physiology and diseases, little is known about ion channel expression, properties and regulation in ocular epithelial cells. Furthermore, human primary epithelial cells have rarely been studied in favor of rat, mouse and especially rabbit animal models. Here, we developed primary human Meibomian gland (hMGEC) and conjunctival (hConEC) epithelial cells.

How to: share and reuse data - challenges and solutions from PrIMAVeRa project.

Background: Data sharing accelerates scientific progress and improves evidence quality. Even though journals and funding institutions require investigators to share data, only a small part of studies made their data publicly available upon publication. The procedures necessary to share retrospective data for re-use in secondary data analysis projects can be cumbersome.

Informed Consent and Shared Decision-Making in Modern Medicine. Case-based Approach, Current Gaps and Practical Proposal.

Advances in personalized medicine and Systems Biology have introduced probabilistic models and error discovery to cardiovascular care, aiding disease prevention and procedural planning. However, clinical application faces cultural, technical, and methodological hurdles. Patient autonomy remains essential, with shared decision-making (SDM) gaining importance in managing complex cardiovascular treatment options.

Diurnal dynamics of the Zbtb14 protein in the ventral hippocampus are disrupted in epileptic mice.

Our previous in silico data indicated an overrepresentation of the ZF5 motif in the promoters of genes in which circadian oscillations are altered in the ventral hippocampus in the pilocarpine model of temporal lobe epilepsy in mice. In this study, we test the hypothesis that the Zbtb14 protein oscillates in the hippocampus in a diurnal manner and that this oscillation is disrupted by epilepsy. We found that Zbtb14 immunostaining is present in the cytoplasm and cell nuclei.

Success of outpatient hysterectomy: V-Notes versus Vaginal hysterectomy.

Study Objective: Vaginal hysterectomy (VH) is the approach of choice for benign uterine conditions and is suitable for outpatient care. Many studies suggest that the vaginal natural orifice transluminal endoscopic surgery (V-Notes) technique is reliable and safe for outpatient surgery, but the literature includes only pilot studies with small cohorts. The aim is to assess the V-Notes technique compared to VH in outpatient settings with a larger cohort.

Vaginal versus Laparoscopic Suture for Vaginal Cuff Closure in Total Robot-Assisted Laparoscopic Hysterectomy: A Multicentric Comparative Study.

Background: Vaginal cuff closure is an important step in hysterectomy. To date, the literature and data on this procedure are inconsistent, and the optimal approach (i.e.

The nucleolin antagonist N6L and paclitaxel combination treatment could be a new promising therapeutic strategy for pancreatic ductal adenocarcinoma therapy.

Pancreatic cancer (PCa) is one of the most devastating cancers with few clinical signs and no truly effective therapy. In recent years, our team has demonstrated that nucleolin antagonists such as N6L could be a therapeutic alternative for this disease. In order to study a possible clinic development of N6L (multivalent pseudopeptide), we undertook to study the effect of combination of N6L with chemotherapies classically used for PCa on the survival of pancreatic cancer cells.
