The socioeconomic burden of hip fractures, the most severe osteoporotic fracture outcome, is increasing and the current clinical risk assessment lacks sensitivity. This study aimed to develop a method for improved prediction of hip fracture by incorporating measurements of bone microstructure and composition derived from high-resolution peripheral quantitative computed tomography (HR-pQCT). In a prospective cohort study of 3028 community-dwelling women aged 75 to 80, all participants answered questionnaires and underwent baseline examinations of anthropometrics and bone by dual x-ray absorptiometry (DXA) and HR-pQCT.

Natural teeth fulfill functional demands by their heterogeneity. The composition and hydroxyapatite (HAp) nanostructured orientation of enamel differ from those of dentin. However, mimicking analogous materials still exhibit a significant challenge.

IVL Swedish Environmental Research Institute, Life Cycle Management, Sustainable Society, Vallhallavägen 81, 114 28, Stockholm, Sweden.
Today's globalised agricultural sector poses significant environmental challenges that are expected to worsen with population growth, increased urbanisation, and with the effects of climate change. In this context, vertical farming systems have gained traction as potential solutions to create a more resilient and sustainable food system. This study aims to evaluate the environmental performance of mixed salad bags from a conventional supply chain and compare it with that of mixed salad supplied by a large-scale vertical farm.

The development of greener substitutes for plastics is gaining massive importance in today's society. This also involves the medical field, where disposable materials are used to grant sterility. Here, a novel protocol using only a water-based solvent for the preparation of bio-based composite foams of actual β-chitin and collagen type I is presented.

Exosomes are extracellular vesicles ranging from 30 to 150 nm in diameter that contain proteins, nucleic acids and other molecules. Produced by virtually all cell types, they travel throughout the body until they reach their target, where they can trigger a wide variety of effects by transferring the molecular cargo to recipient cells. In the context of ocular physiology, exosomes play a very important role in embryological development, the regulation of homeostasis and the immune system, which is crucial for normal vision.
