Using monitoring technologies to care for older persons: Findings from a cross-sectional survey in Switzerland
CONCLUSIONS: Higher acceptance was found for smart wearable devices for elder care purposes compared to the sensors and cameras at home. Presence of actual need such as risk of falling, practical care situations, as well as an overall emphasis on ensuring the safety of older persons, were observed to positively impact the acceptance of technologies. Our findings also impart significance of the role of caregiving stress as a driver to incorporating technical tools in elder care. Further research...
Microbiota-derived indole-3-propionic acid extends lifespan in Drosophila and improves muscle and bone health in mice
Aging is associated with alterations in endogenous tryptophan (TRP) metabolism that contributes to musculoskeletal decline. In this study, we investigated the effects of the microbiota-derived TRP metabolite, indole-3-propionic acid (IPA), on musculoskeletal health in aged mice and lifespan in Drosophila melanogaster. Aged C57BL/6 mice received IPA (20 mg/kg, subcutaneous, three times per week for 12 weeks), while Drosophila were maintained on food supplemented with IPA (100 µM) throughout their...

Inactive ryanodine receptors sustain lysosomal availability for autophagy by promoting ER-lysosomal contact site formation
Lysosomal and endoplasmic reticulum (ER) Ca^(2+) release mutually influence each other's functions. Recent work revealed that ER-located ryanodine receptor(s) (RyR(s)) Ca^(2+) release channels suppress autophagosome turnover by the lysosomes. In familial Alzheimer's disease, inhibiting RyR hyperactivity restored autophagic flux by normalizing lysosomal vacuolar H^(+)-ATPase (vATPase) levels. However, the mechanisms by which RyRs control lysosomal function and how this involves the vATPase remain...
The gut microbiota dysbiosis in geriatric multimorbidity: Pharmacotherapeutic implications, pathophysiological mechanisms, and precision modulation strategies
Aging around the world is accelerating. With that comes the intersection of geriatric multimorbidity and polypharmacy, creating a large uncertainty about the pharmacological efficacy and therapeutic consequences of medications used when multiple concurrent health issues exist. The gut microbiota coordinates the way drugs work through multiple pathways: through the way drugs are metabolised, the way they maintain immune homeostasis, and the way they regulate the epithelial barrier. For these...
A high-throughput, flow cytometry approach to measure phase behavior and exchange in biomolecular condensates
Biomolecular condensates are essential for cellular organization, yet their formation dynamics and molecular content exchange properties remain poorly understood. Here we show that flow cytometry provides a high-throughput, solution-based platform for analyzing condensate behavior at the single-droplet level. Using self-interacting NPM1 condensates as a model, we demonstrate that this approach quantifies phase behavior across protein and salt conditions, measures the partitioning of diverse...
Mechanistically guided residual learning for battery state monitoring throughout life
Battery monitoring requires high accuracy and robustness throughout the entire lifespan to ensure safe and optimal operations. Here we introduce mechanistic leading residual learners to enhance the monitoring of battery charge and health states, as well as guide safety warnings, targeting large-scale applications. Leveraging prior knowledge from real-time filtering as primary guidance, complemented by mechanistic and statistical features, our approach significantly improves accuracy and...
Optimized biomechanical design of a tissue engineered pulsatile Fontan conduit
Children with congenital heart defects increasingly survive to adulthood, but the non-physiological Fontan circulation imposed by current surgical palliation leads to significant sequelae and reduced lifespan. Restoring subpulmonic pumping function remains a long-standing goal, and there have been several attempts using regenerative medicine approaches. These efforts have lacked biomechanical rigor, however, and have not achieved the requisite functionality. Here, we introduce an analytically...
Tailoring polarization homogeneity in discontinuous-columnar Bi(Fe,Mn)O<sub>3</sub> thin films via dislocation engineering with controlled self-assembly
Defect microstructures, particularly dislocations, are pivotal in determining the functional properties of ferroelectric thin films. While their density is routinely considered, the critical role of their spatial configuration has remained largely unexplored and difficult to control. Here, we develop a controlled self-assembly strategy for dislocations in Bi(Fe,Mn)O(3) thin films on Ni-Cr that directly addresses this challenge. By employing a LaNiO(3) buffer layer, we template a...
Trained immunity in acute and chronic neurological diseases
Trained immunity, the long-term reprogramming of innate immune cells to elicit an enhanced response upon subsequent challenges, has become a key concept in understanding a wide range of pathologies, including both acute and chronic inflammatory disorders. Recent evidence suggests that trained immunity also plays a significant role in the development and progression of various neurological disorders and related comorbidities, in which brain pathology can lead to trained immunity. This review...
