Patient perceptions of osteoporosis management: a qualitative pilot study by a patient advisory group.

Unlabelled: The management of osteoporosis even after a fracture is declining. Our pilot study in patients with osteoporosis confirms a large ignorance of the disease and major fears and uncertainties about the treatments. Complete and sustained medical information seems essential to counteract the contradictory information, which are exclusively negative.

A comprehensive study of the influence of non-covalent interactions on electron density redistribution during the reaction between acetic acid and methylamine.

Context: A chemical reaction can be described, from a physicochemical perspective, as a redistribution of electron density. Additionally, non-covalent interactions locally modify the electron density distribution. This study aims to characterize the modification of reactivity caused by the presence of non-covalent interactions such as hydrogen bonds, in a reaction involving the formation of two bonds and the breaking of two others: CH₃COOH + NH₂CH₃ → CH₃CONHCH₃.

Beta cell function and global glucose metabolism are impaired in Dp(16)1Yey mouse model of Down syndrome.

Aims: Down syndrome (DS) or trisomy 21 is the most prevalent genetic disorder in the world. In addition to common symptoms such as intellectual disabilities and morphological abnormalities, several comorbidities are associated with DS, including metabolic dysfunction. Obesity and diabetes are more prevalent in people with DS compared with the general population.

Aptamer-conjugated gold nanoparticles enable oligonucleotide delivery into muscle stem cells to promote regeneration of dystrophic muscles.

Inefficient targeting of muscle stem cells (MuSCs), also called satellite cells, represents a major bottleneck of current therapeutic strategies for muscular dystrophies, as it precludes the possibility of promoting compensatory regeneration. Here we describe a muscle-targeting delivery platform, based on gold nanoparticles, that enables the release of therapeutic oligonucleotides into MuSCs. We demonstrate that AuNPs conjugation to an aptamer against α7/β1 integrin dimers directs either local or systemic delivery of microRNA-206 to MuSCs, thereby promoting muscle regeneration and improving muscle functionality, in a mouse model of Duchenne Muscular Dystrophy.

The Omics-Driven Machine Learning Path to Cost-Effective Precision Medicine in Chronic Kidney Disease.

Chronic kidney disease (CKD) poses a significant and growing global health challenge, making early detection and slowing disease progression essential for improving patient outcomes. Traditional diagnostic methods such as glomerular filtration rate and proteinuria are insufficient to capture the complexity of CKD. In contrast, omics technologies have shed light on the molecular mechanisms of CKD, helping to identify biomarkers for disease assessment and management.

Impulsivity behaviors and white matter mediate the relationship between genetic risk for cannabis use disorder and early cannabis use in adolescents.

Background And Aim: Cannabis use disorder (CUD) is strongly influenced by genetic factors; however the mechanisms underpinning this association are not well understood. This study investigated whether a polygenic risk score (PRS) based on a genome-wide association study for CUD in adults predicts cannabis use in adolescents and whether the association can be explained by inter-individual variation in structural properties of brain white matter or risk-taking behaviors.

Design And Setting: Longitudinal and cross-sectional analyses using data from the IMAGEN cohort, a European longitudinal study integrating genetic, neuroimaging and behavioral measures.

Right Ventricular Injury Definition and Management in Veno-Venous Extracorporeal Membrane Oxygenation.

Right ventricular injury (RVI) in respiratory failure receiving veno-venous extracorporeal membrane oxygenation (VV ECMO) is associated with significant mortality. A scoping review is necessary to map the current literature and guide future research regarding the definition and management of RVI in patients receiving VV ECMO. We searched for relevant publications on RVI in patients receiving VV ECMO in Medline, EMBASE, and Web of Science.

LAP1 Interactome Profiling Provides New Insights into LAP1's Physiological Functions.

The nuclear envelope (NE), a protective membrane bordering the nucleus, is composed of highly specialized proteins that are indispensable for normal cellular activity. Lamina-associated polypeptide 1 (LAP1) is a NE protein whose functions are just beginning to be unveiled. The fact that mutations causing LAP1 deficiency are extremely rare and pathogenic is indicative of its paramount importance to preserving human health, anticipating that LAP1 might have a multifaceted role in the cell.

The Wilms' Tumor Suppressor WT1 in Cardiomyocytes: Implications for Cardiac Homeostasis and Repair.

The Wilms' tumor suppressor WT1 is essential for the development of the heart, among other organs such as the kidneys and gonads. The Wt1 gene encodes a zinc finger transcription factor that regulates proliferation, cellular differentiation processes, and apoptosis. WT1 is also involved in cardiac homeostasis and repair.

Establishing bio-logging data collections as dynamic archives of animal life on Earth.

Rapid growth in bio-logging-the use of animal-borne electronic tags to document the movements, behaviour, physiology and environments of wildlife-offers opportunities to mitigate biodiversity threats and expand digital natural history archives. Here we present a vision to achieve such benefits by accounting for the heterogeneity inherent to bio-logging data and the concerns of those who collect and use them. First, we can enable data integration through standard vocabularies, transfer protocols and aggregation protocols, and drive their wide adoption.

The spatially informed mFISHseq assay resolves biomarker discordance and predicts treatment response in breast cancer.

Current assays fail to address breast cancer's complex biology and accurately predict treatment response. On a retrospective cohort of 1082 female breast tissues, we develop and validate mFISHseq, which integrates multiplexed RNA fluorescent in situ hybridization with RNA-sequencing, guided by laser capture microdissection. This technique ensures tumor purity, unbiased whole transcriptome profiling, and explicitly quantifies intratumoral heterogeneity.

A theoretical study on the environmental oxidation of fenpyrazamine fungicide initiated by hydroxyl radicals in the aqueous phase.

Fenpyrazamine (FPA) is a widely used fungicide in agriculture to control fungal diseases, but its environmental degradation by oxidants and the formation of potential degradation products remain unexplored. This study investigates the oxidation of FPA by hydroxyl radicals (HO˙) using density functional theory (DFT) calculations at the M06-2X/6-311++G(3df,3pd)//M06-2X/6-31+G(d,p) level of theory. Three standard oxidation mechanisms, including formal hydrogen transfer (FHT), radical adduct formation (RAF), and single electron transfer (SET), were evaluated in the aqueous phase, with reaction kinetics analyzed over a temperature range of 283-333 K.

RAFT Dispersion Polymerization of 2-Hydroxyethyl Methacrylate in Non-polar Media.

We report the reversible addition-fragmentation chain transfer (RAFT) dispersion polymerization of 2-hydroxyethyl methacrylate (HEMA) in -dodecane using a poly(lauryl methacrylate) (PLMA) precursor at 90 °C. This formulation is an example of polymerization-induced self-assembly (PISA), which leads to the formation of a colloidal dispersion of spherical PLMA-PHEMA nanoparticles at 10-20% w/w solids. PISA syntheses involving polar monomers in non-polar media have been previously reported but this particular system offers some unexpected and interesting challenges in terms of both synthesis and characterization.

Performance of phenomic selection in rice: Effects of population size and genotype-environment interactions on predictive ability.

Phenomic prediction (PP), a novel approach utilizing Near Infrared Spectroscopy (NIRS) data, offers an alternative to genomic prediction (GP) for breeding applications. In PP, a hyperspectral relationship matrix replaces the genomic relationship matrix, potentially capturing both additive and non-additive genetic effects. While PP boasts advantages in cost and throughput compared to GP, the factors influencing its accuracy remain unclear and need to be defined.

Deconstruction of a memory engram reveals distinct ensembles recruited at learning.

How are associative memories formed? Which cells represent a memory, and when are they engaged? By visualizing and tagging cells based on their calcium influx with unparalleled temporal precision, we identified non-overlapping dorsal CA1 neuronal ensembles that are differentially active during associative fear memory acquisition. We dissected the acquisition experience into periods during which salient stimuli were presented or certain mouse behaviors occurred and found that cells associated with specific acquisition periods are sufficient alone to drive memory expression and contribute to fear engram formation. This study delineated the different identities of the cell ensembles active during learning, and revealed, for the first time, which ones form the core engram and are essential for memory formation and recall.

Best Subset Solution Path for Linear Dimension Reduction Models Using Continuous Optimization.

The selection of best variables is a challenging problem in supervised and unsupervised learning, especially in high-dimensional contexts where the number of variables is usually much larger than the number of observations. In this paper, we focus on two multivariate statistical methods: principal components analysis and partial least squares. Both approaches are popular linear dimension-reduction methods with numerous applications in several fields including in genomics, biology, environmental science, and engineering.

Acute kidney injury as a key predictor of cardiovascular events in chronic kidney disease patients: the CKD-REIN study.

Background And Hypothesis: Cardiovascular diseases are a leading cause of morbidity and mortality in patients with chronic kidney disease (CKD). Acute kidney injury (AKI) has been increasingly recognized as a potential exacerbating factor for cardiovascular events in these patients. The CKD-REIN study aims to explore the relationship between AKI and the risk of major adverse cardiovascular events (MACE) in a cohort of CKD patients.

Crystal structure of the human LAG-3-HLA-DR1-peptide complex.

T cell activity is governed by T cell receptor (TCR) signaling and constrained by immune checkpoint molecules, including programmed cell death protein 1 (PD-1), cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), and lymphocyte activation gene 3 (LAG-3). The basis for how LAG-3 binds to human leukocyte antigen class II molecules (HLA-II) remains unknown. Here, we present the 3.

Distal Pancreatectomy with Celiac Axis and Venous Resection with Hepatic Artery and Venous Reconstruction (DP-CARV) for Locally Advanced Pancreatic Adenocarcinoma.

Background: Surgery has recently been introduced into the multimodal management of patients with locally advanced pancreatic adenocarcinomas (LAPCs) thanks to the major pathological response seen with the advent of the multiagent regimen FOLFIRINOX. Distal pancreatectomy with celiac axis resection (DP-CAR) may be complicated by ischemic liver and gastric events. Common hepatic artery reconstruction may prevent the occurrence of ischemic complications and can be an alternative to preoperative embolization of the celiac trunk.

From eggs to adulthood: sustained effects of early developmental temperature and corticosterone exposure on physiology and body size in an Australian lizard.

Developing animals are increasingly exposed to elevated temperatures as global temperatures rise as a result of climate change. Vertebrates can be affected by elevated temperatures during development directly, and indirectly through maternal effects (e.g.
