Cognitive impairment among older adults in India: understanding the role of substance use and lifestyle factors
CONCLUSIONS: Substance use and other lifestyle factors are significantly associated with cognitive impairment among the older adults in India. Therefore, encouraging older adults who use tobacco or alcohol to assess their cognitive function at an earlier stage that could prevent or mitigate cognitive impairment, thereby enhancing their quality of life. This contribute to achieve of Sustainable Development Goals, particularly Goal 3 that guaranteeing good health and wellbeing for all.
A nanoMIP sensor for real-time in vivo monitoring of levodopa pharmacokinetics in precision Parkinson's therapy
Real-time in vivo monitoring of levodopa pharmacokinetics is essential to address its narrow therapeutic window in Parkinson's disease (PD) therapy. However, current methods require excessive sample volumes, suffer low sampling frequencies, and fail to capture complete pharmacokinetic profiles. Here, we present an in vivo monitoring system for real-time tracking of levodopa levels in interstitial fluid (ISF) using a spindle-shaped carbon nanotube (CNT) fiber electrochemical sensor functionalized...
Molecular mechanism of PINK1 regulation by the Hsp90 machinery
Hundreds of human kinases, including PINK1-a protein kinase associated with familial Parkinson's disease-are regulated by Hsp90 and its cochaperones. While previous studies have elucidated the mechanism of kinase loading into the Hsp90 machinery, the subsequent regulation of kinases by Hsp90 and its cochaperones remains poorly understood. In this study, using complexes obtained through PINK1 pulldown, we determine the cryo-EM structures of the human Hsp90-Cdc37-PINK1 complex at 2.84 Å,...
Liraglutide in mild to moderate Alzheimer's disease: a phase 2b clinical trial
Liraglutide, a glucagon-like peptide 1 (GLP-1) agonist and antidiabetic drug, has shown neuroprotective effects in animal models. In this study, we aimed to evaluate the safety and efficacy of liraglutide in mild to moderate Alzheimer's disease syndrome. 'Evaluating liraglutide in Alzheimer's disease' (ELAD) is a multicenter, randomized, double-blind, placebo-controlled phase 2b trial in 204 participants with mild to moderate Alzheimer's disease syndrome with no diabetes. Participants received...
Sea urchin bioactive compounds: emerging interventions for age-related diseases
Among the marine bioresources, sea urchins are emerging as a promising provider of bioactive compounds with broad therapeutic potentials, including for ageing and age-related diseases. This review highlights the therapeutic promise of sea urchin bioactive compounds, covering evidence from both laboratory and clinical studies. Compounds found in sea urchin such as carotenoids, polyhydroxynaphthoquinones (PHNQs), and flavonoids demonstrate antioxidant and anti-inflammatory properties with notable...
Dietary lipid content modifies wah-1/AIFM1-associated phenotypes via LRK-1 and DRP-1 expression in C. elegans
Eukaryotic cells rely on mitochondria to fine-tune their metabolism in response to environmental and nutritional changes. However, how mitochondria adapt to nutrient availability and how diets impact mitochondrial disease progression, remain unclear. Here, we show that lipid-derived diets influence the survival of Caenorhabditis elegans carrying a hypomorphic wah-1/AIFM1 mutation that compromises mitochondrial Complex I assembly. Comparative proteomic and lipidomic analyses reveal that the...
Oxidized phosphatidylcholines deposition drives chronic neurodegeneration in a mouse model of progressive multiple sclerosis via IL-1β signaling
Oxidized phosphatidylcholines (OxPCs) are neurotoxic byproducts of oxidative stress elevated in the central nervous system (CNS) during progressive multiple sclerosis (P-MS). How OxPCs contribute to the pathophysiology of P-MS is unclear. Here we show that stereotactic OxPC deposition in the CNS of mice induces a chronic compartmentalized lesion with pathological features similar to chronic active lesions found in P-MS. Using this model, we found that although microglia protected the CNS from...
Intergenerational approach of community dance program for older adults in singapore: a feasibility cluster-controlled trial
CONCLUSION: These preliminary findings suggest potential benefits of the dance intervention for physical and psychosocial well-being among older adults, warranting further evaluation in larger, adequately powered randomized studies. Future research can investigate the pathways of how intergenerational dance intervention may enhance older adults' cognitive, physical, and psychosocial function over a longer term, as well as the relationships among these variables. Hence, more comprehensive and...
Prevalence and factors associated with sarcopenia risk among older adults with diabetes: an exploratory network analysis
CONCLUSION: Our findings highlight unhappiness as the key factor in the sarcopenia risk network among older adults with diabetes. The key factors vary across different age and diabetes duration, highlighting the necessity of tailoring intervention strategies to individual patients. Objective support demonstrates a broad impact on sarcopenia risk across this population.
