Adv Healthc Mater

January 2025

Department of Clinical and Experimental Biomedical Sciences, University of Florence, Viale G.B. Morgagni, 50, Florence, 50134, Italy.

Mimicking compositions and structures of extracellular matrix is widely studied to create in vitro tumor models, to deepen the understanding of the pathogenesis of the different types of cancer, and to identify new therapies. On the other hand, the use of synthetic materials to modulate cancer cell biology and, possibly, to reduce the malignancy of cancer cells through their exploitation is far less explored. Here, the study evaluates the effects of Liquid Crystalline Networks (LCNs) based scaffolds on the growth of A375 metastatic melanoma cells.

Although intense research effort is seeking to address which brain areas fire and connect to each other to produce complex behaviors in a few living primates, little is known about their evolution, and which brain areas or facets of cognition were favored by natural selection. By developing statistical tools to study the evolution of the brain cortex at the fine scale, we found that rapid cortical expansion in the prefrontal region took place early on during the evolution of primates. In anthropoids, fast-expanding cortical areas extended to the posterior parietal cortex.

Usnic acid (UA) is one of the most abundant secondary metabolites of lichens. Its antibacterial, anti-inflammatory, antiviral, and antitumor properties make it one of the few commercially available lichens compounds. Owing to its low solubility it has limited application, for that reason encapsulation in polymeric micelles (UA-PM) has been used to solve this aspect.

To get further insights on the micro-nanoplastic (MNP) effects on plants, the aim of this study was to evaluate the response of hydroponically cultivated Arabidopsis thaliana to the presence of differentially colored polyethylene terephthalate (PET) particles. MNP impacts on the root organ were studied at a molecular level, with a special focus on the role of long non-coding RNAs (lncRNAS) in the regulation of gene expression after PET exposure. MNPs of transparent (Tr-PET) and blue (Bl-PET) material at environmentally realistic concentration caused a significant reduction in root length, while only Bl-PET significantly reduced rosette area.

Intramammary dry-off treatment is widely considered an effective method for preventing and curing intramammary infection (IMI) in lactating cows; however, it is not commonly used in small ruminants like goats. Therefore, this study was designed to evaluate the effect of an approved cefazolin-based intramammary treatment on the milk microbiota of Alpine dairy goats during the dry and early lactation periods. Sixty goats were randomly selected based on bacteriological results and randomly allocated into the control group (CG) or the treatment group (TG).

The linear vibronic coupling (LVC) model is an approach for approximating how a molecular Hamiltonian changes in response to small changes in molecular geometry. The LVC framework thus has the ability to approximate molecular Hamiltonians at low computational expense but with quality approaching multiconfigurational calculations, when the change in geometry compared to the reference calculation used to parametrize it is small. Here, we show how the LVC approach can be used to project approximate spin Hamiltonians of a solvated lanthanide complex along a room-temperature molecular dynamics trajectory.

Inoculation with the PGPB Herbaspirillum seropedicae shapes both the structure and putative functions of the wheat microbiome and causes changes in the levels of various plant metabolites described to be involved in plant growth and health. Plant growth promoting bacteria (PGPB) can establish metabolic imprints in their hosts, contributing to the improvement of plant health in different ways. However, while PGPB imprints on plant metabolism have been extensively characterized, much less is known regarding those affecting plant indigenous microbiomes, and hence it remains unknown whether both processes occur simultaneously.

The recent evidences provided in metastatic hormone sensitive prostate cancer (nmHSPC) and in nonmetastatic castration resistant (nmCRPC) introduced the possibility to adopt Androgen Receptor Signaling inhibitor (ARSi) alone (both settings) or with chemotherapy (in mHSPC). In daily clinical practice there are some opening questions regarding the inclusion of next generation imaging, mainly PSMA-PET, how integrate local treatment as radiotherapy, how to select patients or drugs in a multiple-choice scenario, and how to manage patients with comorbidities and polypharmacy. These issues led the Italian Society for Uro-Oncology (SIUrO) to develop a consensus project involving all of the most important Italian scientific societies engaged in the multidisciplinary and multiprofessional management of the disease.

Metabolic alterations, including hypermetabolism, lipid imbalances, and glucose dysregulation, are pivotal contributors to the onset and progression of Amyotrophic Lateral Sclerosis (ALS). These changes exacerbate systemic energy deficits, heighten oxidative stress, and fuel neuroinflammation. Simultaneously, gastrointestinal dysfunction and gut microbiota (GM) dysbiosis intensify disease pathology by driving immune dysregulation, compromising the intestinal barrier, and altering gut-brain axis (GBA) signaling, and lastly advancing neurodegeneration.
