Mechanical and functional characterisation of a 3D porous biomimetic extracellular matrix to study insulin secretion from pancreatic β-cell lines.

Background: Extracellular matrix (ECM) is a three-dimensional (3D) structure found around cells in the tissues of many organisms. It is composed mainly of fibrous proteins, such as collagen and elastin, and adhesive glycoproteins, such as fibronectin and laminin-as well as proteoglycans, such as hyaluronic acid. The ECM performs several essential functions, including structural support of tissues, regulation of cell communication, adhesion, migration, and differentiation by providing biochemical and biomechanical cues to the cells.

Unlabelled: This study addresses longstanding questions concerning the ore sources used in the first series of coins of ancient Athens known as the (c.540-c.500 BCE) by combining comprehensive numismatic data on 22 coins (16 new and 6 legacy analyses) with lead isotope and surface elemental measurements (MC-ICP-MS and XRF).

Deltopectoral approach without subscapularis detachment for reverse shoulder arthroplasty. Technique and results of a safe and reproducible subscapularis-sparing approach.

Background: The importance of the subscapularis for reverse total shoulder arthroplasty has been demonstrated, especially for internal rotation and stability. In a deltopectoral approach, a detachment of the subscapularis is performed (tenotomy, tuberosity peeling, or osteotomy), but the tendon is not always repairable at the end. When it is repaired, healing is obtained in only 40%-76% of the cases, with potential consequences for the outcomes.

Fade into you: genetic control of pigmentation patterns in red-flesh apple ().

The genetic basis of type 1 red-flesh color development in apple () depends upon a particular allele of the gene. Interestingly, type 1 red-flesh apples are fully red after fruit set, but anthocyanin pigmentation in apple fruit cortex may decrease during fruit growth and maturation, leading to variable red patterning and intensities in the mature cortical flesh. We developed a histogram-based color analysis method to quantitatively estimate pigmentation patterns.

A multi-country cohort database study to assess pregnancy and infant outcomes after potential maternal or paternal exposure to cladribine tablets in the treatment of multiple sclerosis: the CLEAR study methods and status update.

Machine learning Hubbard parameters with equivariant neural networks.

Density-functional theory with extended Hubbard functionals (DFT +  + ) provides a robust framework to accurately describe complex materials containing transition-metal or rare-earth elements. It does so by mitigating self-interaction errors inherent to semi-local functionals which are particularly pronounced in systems with partially-filled d and f electronic states. However, achieving accuracy in this approach hinges upon the accurate determination of the on-site and inter-site Hubbard parameters.

Understanding trends in osteoporosis drug prescribing: implications for reducing futile biomedical research.

Introduction: Osteoporosis is a significant geriatric condition, considering its impact on fracture-related morbidity and mortality, particularly among older women. The interplay of clinical evidence, diagnostic tools availability, and broader societal attitudes toward aging and treatment efficacy affect medical attitude and prescribing behaviors. Using the example of osteoporosis in France and England, the study aims to unravel the intricacies of medical decision-making in geriatric care, offering insights into the evolving landscape of healthcare policy and practice, which in turn can help reduce futile biomedical research.

Innovation Leading to Improved Safety, Health, and Productivity Is Enabled by Close Collaboration Between Construction Companies and Technology Start-Ups.

The transfer of innovation to practice is one of the fundamental challenges of efficient social advancement. Because of its structure, with mostly small employers with limited working capital and short-term thinking arising from working on time-limited projects, historically the construction industry has been a slow adopter of technological advances. Now it is faced with a barrage of new technologies that not only can help solve some of the most pressing occupational safety and health needs but at the same time also contribute to productivity improvements.

Applications of Cell-Based Protein Array Technology to Preclinical Safety Assessment of Biological Products.

Off-target evaluation is essential in preclinical safety assessments of novel biotherapeutics, supporting lead molecule selection, endpoint selection in toxicology studies, and regulatory requirements for first-in-human trials. Off-target interaction of a therapeutic antibody and antibody derivatives has been historically assessed via the Tissue Cross-Reactivity (TCR) study, in which the candidate molecule is used as a reagent in immunohistochemistry (IHC) to assess binding of the candidate molecule to a panel of human tissue sections. The TCR approach is limited by the performance of the therapeutic as an IHC reagent, which is often suboptimal to outright infeasible.

The impact of pre-treatment aneurysm angulation. What happens with WEB devices at follow-up?

Multispecies comparisons support a startle response origin for a novel vibrational signal in the cricket tribe Lebinthini.

Many animals communicate using call and response signals, but the evolutionary origins of this type of communication are largely unknown. In most cricket species, males sing and females walk or fly to calling males. In the tribe Lebinthini, however, males produce calls that trigger a vibrational reply from females, and males use the substrate vibrations to find the responding female.

Endothelial Dysfunction in Acute Myocardial Infarction: A Complex Association With Sleep Health, Traditional Cardiovascular Risk Factors and Prognostic Markers.

Background: Endothelial function (EndFx) is a core component of cardiovascular (CV) health and cardioprotection following acute myocardial infarction (AMI) treated with primary percutaneous coronary intervention (PCI).

Hypothesis: AMI patients experience endothelial dysfunction (EndDys), associated with traditional CV risk factors and sleep patterns. EndFx may also predict short and mid-term outcomes.
