Clinical Implications of Functional Imaging in the Assessment of Bronchiectasis-Associated Sarcopenia.

Introduction: Bronchiectasis is a complex lung disease with poorly studied systemic manifestations. Patients with bronchiectasis-associated sarcopenia exhibit a specific differential profile of functional muscle phenotype (vastus lateralis, VL), which may be analyzed using imaging (ultrasound and magnetic resonance imaging, MRI).

Methods: Ultrasound and MRI were used to explore functional imaging parameters in quadriceps of 20 patients with stable bronchiectasis and 10 healthy controls.

Arabidopsis root apical meristem adaptation to an osmotic gradient condition: an integrated approach from cell expansion to gene expression.

Climate change triggers abiotic stress, such as drought and high salinity, that can cause osmotic stress. Water availability can limit plant growth, and the root tip tissues initially sense it. Most experiments destined to understand root growth adaptation to osmotic stress apply homogeneous high osmotic potentials (osmotic shock) to shoots and roots.

Plasma Neurodegenerative Biomarkers in Cognitively Preserved Nonagenarians.

Plasma biomarkers represent promising tools for the screening and diagnosis of patients with neurodegenerative conditions. However, it is crucial to account for the effects of aging on biomarker profiles, especially in the oldest segments of the population. Additionally, biomarkers in this sample can offer in vivo insights into the physiological mechanisms underlying brain aging while concomitantly supporting cognitive preservation.

Harnessing salinity gradient energy: Pushing forward in water reclamation via on-site reverse electrodialysis technology.

Effluents from urban wastewater treatment plants (UWWTPs) discharged into water bodies such as the sea or ocean, offer a potential source of renewable energy through the salinity gradient (SGE) between seawater and treated water. The European project Life-3E: Environment-Energy-Economy aims to demonstrate an innovative process integrating renewable energy production with water reclamation. Using reverse electrodialysis (RED) technology, SGE can power tertiary wastewater treatment processes in coastal UWWTPs, offsetting energy costs associated with water regeneration and reuse.

The mediating role of attributions of poverty and wealth in the relationship between perceptions of economic inequality and redistribution preferences.

Previous research has identified that the relationship between perceived economic inequality and supporting redistribution is mediated by beliefs about what causes poverty. Despite its usefulness, this approach has failed to recognize the role of perceived causes of wealth in explaining the relationship between these two variables. We conducted correlational ( = 523) and experimental ( = 226) studies, demonstrating that in contexts with high inequality, attributing poverty and wealth primarily to external factors resulted in greater support for redistribution.
