Alterations in cortical sulcal morphology in Parkinson's disease patients with impulse control disorders

2 weeks 6 days ago
Impulse control disorders, debilitating non-motor complications of Parkinson's disease, are linked to dopaminergic therapy and mesocorticolimbic dysfunction. This study aimed to characterize cortical sulcal depth, a sensitive morphometric index of cortical folding, and cortical thickness and subcortical volumetric alterations in Parkinson's disease patients with impulse control disorders. Sixty-eight Parkinson's disease patients (30 with impulse control disorders, 38 without impulse control...

Frailty and the brain: A narrative review of functional and pathological correlates

2 weeks 6 days ago
Frailty influences the risk, phenotypic expression, and course of highly prevalent neurological conditions. However, the structural, functional, and pathological changes in the brain associated with frailty remain insufficiently explored. This narrative review examines existing evidence on the functional and pathological brain correlates of frailty in both healthy adults and patients with neurological conditions, encompassing findings from neuropathology, fluid biomarkers, neuroimaging, and...

Spinal cord Tau pathology induces tactile deficits and cognitive impairment in Alzheimer's disease via dysregulation of CCK neurons

2 weeks 6 days ago
Somatosensory processing has been shown to be correlated with brain development and cognitive function, but whether and how tactile sensory deficits affect cognition decline remains unclear. Here we show that tactile function is impaired in individuals with Alzheimer's disease (AD), and this impairment is inversely correlated with Montreal Cognitive Assessment scores and positively correlated with Tau pathology. We observed similar deficits in presymptomatic 3×Tg AD mice and find that...

Association between complication risk perception and medical coping strategies in older adults with type 2 diabetes: a cross-sectional study

2 weeks 6 days ago
CONCLUSION: These results underscore the importance of assessing and addressing perceived risk levels in this population, to promote proactive and effective coping mechanisms. Such efforts may help prevent or delay diabetes-related complications and enhance the quality of life for older adults with type 2 diabetes. Moreover, the findings provide an evidence-based foundation for the development of targeted clinical interventions.

Mitochondrial Respiratory Supercomplex Assembly Factor COX7RP Contributes to Lifespan Extension in Mice

2 weeks 6 days ago
COX7RP is a critical factor that assembles mitochondrial respiratory chain complexes into supercomplexes, which is considered to modulate energy production efficiency. Whether COX7RP contributes to metabolic homeostasis and lifespan remains elusive. We here observed that COX7RP-transgenic (COX7RP-Tg) mice exhibit a phenotype characterized by a significant extension of lifespan. In addition, metabolic alterations were observed in COX7RP-Tg mice, including lower blood glucose levels at 120 min...

Mitigating residual MA<sup>+</sup> for stable FAPbI<sub>3</sub> perovskite photovoltaics

2 weeks 6 days ago
Perovskite solar cells (PSCs) based on formamidinium lead iodide (FAPbI₃) demonstrate near-ideal bandgaps approaching the Shockley-Queisser efficiency limit, yet residual MA⁺ from methylammonium chloride (MACl) additives compromises their operational stability under thermal/light stress. Therefore, we developed an α-phase-assisted antisolvent method employing MACl-free precursors to fabricate α-FAPbI(3) films. These films exhibit enhanced thermal stability and structural integrity, which were...

Towards global healthy longevity: report from the 1st World Longevity Summit in Kyotango, Japan

2 weeks 6 days ago
Aging societies around the world face increasing challenges in promoting healthy longevity. The 1st World Longevity Summit in Kyotango, Japan, convened experts to discuss advances in aging biology, lifestyle medicine, and community-based health strategies. The joint declaration outlined four pillars for healthy aging: bonds with communication, dietary fiber, physical activity, and “Ikigai”, a sense of purpose. This report highlights representative summit discussions and presents key insights on...

Unveiling the importance of SIRT5 for cardiac health and disease in an era of increasing longevity

2 weeks 6 days ago
As the world's population ages, strategies to promote healthy longevity are critical. SIRT5, belonging to the sirtuin family, plays a key role in regulating cellular metabolism and mitochondrial homeostasis by removing post-translational modifications such as succinylation, malonylation, and glutarylisation from lysine residues of proteins. Herein, we discuss the multifunctionality of SIRT5, its impact on heart function, and its involvement as a target in geroscience for the pathogenesis of...

Redefining the concept of erythrocyte senescence: is eryptosis fundamentally different from erythrocyte senescence

2 weeks 6 days ago
In response to acute stress, nucleated cells undergo various regulated cell deaths (RCDs). Alternatively and in the long run, they permanently stop proliferating with the parallel acquisition of apoptosis resistance and the senescence-associated secretory phenotype. This particular long-term stress response is referred to as cellular senescence. Terminally differentiated, anucleate red blood cells (RBCs) cannot proliferate anymore and are incapable of synthesizing proteins. RBC senescence is...

Catalytic electrolytes enable fast reaction kinetics and temperature adaptability for aqueous zinc-bromine flow batteries

2 weeks 6 days ago
Catalysts are widely used to improve electrode reactions in static batteries. However, due to aqueous flow batteries utilizing large volumes of electrolytes, previously reported non-flowable solid-phase catalysts are inadequate for addressing challenges such as low conversion ratios and electrolyte failure, especially under low-temperature conditions. Herein, we develop functionalized carbon quantum dot-based colloidal catalytic electrolytes for Zn-Br flow batteries. This approach deviates from...
