Functional alignment in robotic-assisted total knee arthroplasty for valgus deformity achieves safe coronal alignment and excellent short-term outcomes.

Purpose: Functional alignment (FA) in total knee arthroplasty (TKA) prioritizes soft tissue balancing and anatomical restoration without systematic correction to neutral alignment. Most studies have focused on varus deformity, with little evidence available about FA in valgus deformity. The hypothesis of the present study was that FA in robotic-assisted TKA for valgus deformity would demonstrate correction of the coronal alignment and yield satisfactory short-term outcomes.

Plasma N-terminal tau fragment is an amyloid-dependent biomarker in Alzheimer's disease.

Introduction: Novel fluid biomarkers for tracking neurodegeneration specific to Alzheimer's disease (AD) are greatly needed.

Methods: Using two independent well-characterized cohorts (n = 881 in total), we investigated the group differences in plasma N-terminal tau (NT1-tau) fragments across different AD stages and their association with cross-sectional and longitudinal amyloid beta (Aβ) plaques, tau tangles, brain atrophy, and cognitive decline.

Results: Plasma NT1-tau significantly increased in symptomatic AD and displayed positive associations with Aβ PET (positron emission tomography) and tau PET.

Harnessing Multi-Center-2-Electron Bonds for Carbene Metal-Hydride Nanocluster Catalysis.

N-Heterocyclic carbene (NHC) ligands possess the ability to stabilize metal-based nanomaterials for a broad range of applications. With respect to metal-hydride nanomaterials, however, carbenes are rare, which is surprising if one considers the importance of metal-hydride bonds across the chemical sciences. In this study, we introduce a bottom-up approach leveraging preexisting metal-metal m-center-n-electron (mc-ne) bonds to access a highly stable cyclic(alkyl)amino carbene (CAAC) copper-hydride nanocluster, [(CAAC)6Cu14H12][OTf]2 with superior stability compared to Stryker's reagent, a popular commercial phosphine-based copper hydride catalyst.

Quality of life identification by unsupervised cluster analysis: A new approach to modelling the burden of endometriosis.

Background: Symptoms frequently associated with endometriosis affect quality of life (QoL). Our aim investigated the hypothesis that cluster analysis can be used to identify homogeneous phenotyping subgroups of women according to the burden of the endometriosis for their QoL, and then to investigate the phenotype differences observed between these subgroups.

Methods: We developed an anonymous online survey, which received responses from 1,586 French women with endometriosis.

Nonconvulsive status epilepticus in patients under intensive care: Should we view epilepsy as a sleep disorder?

Nonconvulsive status epilepticus (NCSE) was initially described in patients with typical and atypical absence status epilepticus (ASE) characterized by states of confusion varying in severity and in focal epilepsies with or without alteration of consciousness. Continuous EEG monitoring of critically ill patients has further refined the classification of NCSE into two main categories: with coma and without coma. Hypnotic, soporific or somniferous epileptic seizures do not exist.

Advancing biomonitoring of eDNA studies with the Anaconda R package: Integrating soil and One Health perspectives in the face of evolving traditional agriculture practices.

Soil health and One Health are global concerns, necessitating the development of refined indicators for effective monitoring. In response, we present the Anaconda R Package, a novel tool designed to enhance the analysis of eDNA data for biomonitoring purposes. Employing a combination of different approaches, this package allows for a comprehensive investigation of species abundance and community composition under diverse conditions.

Chemistry, manufacturing and controls strategies for using novel excipients in lipid nanoparticles.

Lipid nanoparticles (LNPs) for nucleic acid delivery often use novel lipids as functional excipients to modulate the biodistribution, pharmacokinetics, pharmacodynamics and efficacy of the nucleic acid. Novel excipients used in pharmaceutical products are subject to heightened regulatory scrutiny and often require data packages comparable to an active pharmaceutical ingredient. Although these regulatory requirements may help to ensure patient safety they also create economic and procedural barriers that can disincentivize innovation and delay clinical investigation.

Physiological and behavioral stability of newborns on therapeutic hypothermia for hypoxic-ischemic encephalopathy during parental holding.

Background: Physical separation contributes to parental trauma and poor bonding in the context of therapeutic hypothermia (TH) for hypoxic-ischemic encephalopathy (HIE). Parental holding (PH) may improve parents' experience. We aim to determine the physiological and behavioral stability of the newborn held by the parents during TH.

TSLP and TSLPr Expression and Localization in the Airways of COPD and Non-COPD Patients.

Thymic stromal lymphopoietin (TSLP) is an alarmin cytokine activated by allergens, pathogens, and air pollutants. Recent studies suggest TSLP dysregulation in chronic inflammatory diseases. It was highlighted as a key player in the context of asthma-associated mucosal immunity.

Classification of Breast Cancer Through the Perspective of Cell Identity Models.

The mammary epithelium has an inner luminal layer that contains estrogen receptor (ER)-positive hormone-sensing cells and ER-negative alveolar/secretory cells, and an outer basal layer that contains myoepithelial/stem cells. Most human tumours resemble either hormone-sensing cells or alveolar/secretory cells. The most widely used molecular classification, the Intrinsic classification, assigns hormone-sensing tumours to Luminal A/B and human epidermal growth factor 2-enriched (HER2E)/molecular apocrine (MA)/luminal androgen receptor (LAR)-positive classes, and alveolar/secretory tumours to the Basal-like class.

Patient-Derived Xenografts of Breast Cancer.

Patient-derived xenografts (PDX) of breast cancer, obtained from the engraftment of tumour samples into immunodeficient mice, are the most effective preclinical models for studying the biology of human breast cancer and for the evaluation of new anti-cancer treatments. Notably, breast cancer PDX preserve the phenotypic and molecular characteristics of the donor tumours and reproduce the diversity of breast cancer. This preservation of breast cancer biology involves a number of different aspects, including tumour architecture and morphology, patterns of genomic alterations and gene expression, mutational status, and intra-tumour heterogeneity.

Recording Lineage History with Cellular Barcodes in the Mammary Epithelium and in Breast Cancer.

Lineage tracing methods have extensively advanced our understanding of physiological cell behaviour in vivo and in situ and have vastly contributed to decipher the phylogeny and cellular hierarchies during normal and tumour development. In recent years, increasingly complex systems have been developed to track thousands of cells within a given tissue or even entire organisms. Cellular barcoding comprises all techniques designed to genetically label single cells with unique DNA sequences or with a combination of fluorescent proteins, in order to trace their history and lineage production in space and time.

Association Between Local Skin Reactions and Efficacy with 5-Fluorouracil 4% Cream in Actinic Keratosis: A Post-Hoc Analysis of Two Randomised Clinical Trials.

Introduction: Topical 5-fluorouracil (5-FU), 5% or 4% cream, is recommended among first-line treatments for actinic keratosis (AK). Local skin reactions (LSRs) are an expected and transient response to treatment with 5-FU but can lead to treatment discontinuation when severe. This analysis aimed to investigate whether the severity of LSRs during the treatment was associated with lesion clearance assessed 4 weeks after completing treatment.

Calorie (energy) labelling for changing selection and consumption of food or alcohol.

Background: Overconsumption of food and consumption of any amount of alcohol increases the risk of non-communicable diseases. Calorie (energy) labelling is advocated as a means to reduce energy intake from food and alcoholic drinks. However, there is continued uncertainty about these potential impacts, with a 2018 Cochrane review identifying only a small body of low-certainty evidence.

Does motivation lead to academic success, or conversely? Reciprocal relations between autonomous and controlled motivation, and mathematics achievement.

Background: While it's clear that autonomous motivation significantly boosts academic success, there are conflicting findings regarding the opposite relation. Besides, the reciprocal relations among controlled motivation and achievement present mixed results. Adequately distinguishing between variations among individuals and within individuals results key to acknowledge such relations.
