An exploration of demographic and conceptual factors related to attitudes towards dementia
CONCLUSIONS: Our findings showed that age, gender, experience, attitudes toward aging, and wisdom were related to attitudes toward dementia. This evidence could serve as a guide of practical implications in stigma-reduction campaigns, dementia education, and policy reform.
Health status and lifestyle behaviours of older adults in a Hilly Municipality of Dhankuta, Nepal
CONCLUSION: The findings indicate a high burden of self-reported chronic health problems and functional dependency among older adults in a hilly municipality of Nepal. Marital status, smoking, and physical activity were significantly associated with chronic illness, while age and chronic illness were significantly associated with ADL dependency. These results highlight the need for community-based geriatric screening and targeted behavioural interventions to improve health status among older...
Aging self-stereotypes and associated factors among elderly patients with multimorbidity undergoing elective surgery: a cross-sectional study
CONCLUSIONS: Elderly patients with multimorbidity who underwent elective surgeries have high aging self‑stereotype scores, which are independently associated with first‑time surgery, multimorbidity burden, and decision‑making preference. A management model that combines multidisciplinary collaboration with family support should be established to reduce negative stereotypes and improve quality of life among these patients.
Long-term care insurance pilot exposure and severe-depression risk among older adults with baseline severe IADL impairment: a panel difference-in-difference-in-differences analysis
CONCLUSIONS: The findings suggest that the psychological consequences of LTCI exposure may be more visible in the upper tail of the depression distribution among older adults with high care needs than in average mental-health indicators, with the signal appearing stronger in women in exploratory analyses. Policy evaluation should therefore move beyond mean-based indicators and strengthen needs-matched, psychologically supportive long-term care for vulnerable older adults.
The relationship between depressive symptoms and instrumental activities of daily living among older adults in China and its associations with age, sex, and outdoor activity engagement
CONCLUSIONS: In this cross-sectional study in China, exposure to depressive symptoms was associated with IADL disability. This association was modified by age, sex, and outdoor activity engagement. These findings indicate a need to prevent depressive symptoms and a need for an intervention strategy for mental health to reduce the potential risk of IADL disability. Moreover, emphasizing personalized interventions that target individuals with depressive symptoms exposure may minimize the burden of...
Engineering Extracellular Vesicles for Anti-Aging Therapy: Mechanisms, Applications, and Perspectives
Aging is a multifactorial process driven by interconnected hallmarks, including chronic inflammation, mitochondrial dysfunction, genomic and epigenetic alterations, and dysregulated intercellular communication. Extracellular vesicles (EVs), naturally derived nanoscale membrane vesicles capable of transporting diverse bioactive cargoes across tissues and biological barriers, have emerged as a highly promising platform for regenerative and anti-aging therapeutics. In this review, we systematically...
Why science needs the humanities more than ever
‘Us’ not ‘them’: scientists must use their skills to help stop polarization and division
The tea in your kombucha changes more than just the taste
Scientists discovered that kombucha’s flavor, chemistry, and antioxidant activity vary dramatically depending on the tea used to make it. Green and oolong tea kombuchas emerged as the most biologically active, while fermentation transformed each tea into a distinctly different beverage.
Scientists finally solved how H5N1 bird flu hid in dairy cows
Researchers uncovered why H5N1 bird flu attacks cows’ udders instead of their lungs: the virus’s preferred receptors are concentrated in mammary tissue. The breakthrough could help scientists predict future bird flu jumps and spot unusual infections before they spread widely.
New brain study reveals speech learning works differently than we thought
A new study suggests that learning and remembering speech relies more on how the brain processes sounds and sensations than on the areas that control mouth and face movements. The discovery could reshape speech therapy and help improve future brain-based communication technologies.
One of the world’s most popular weedkillers may be fueling deadly superbugs
Researchers found that highly drug-resistant bacteria from hospitals are also resistant to glyphosate, a commonly used weedkiller. The discovery suggests that agricultural herbicides may be helping antibiotic-resistant microbes survive and spread far beyond healthcare settings.
How AI, $1 billion, and a transparent fish could transform neuroscience
The once-obscure Danionella fish takes center stage as a model research organism in a major new project funded by Howard Hughes Medical Institute
Bromodomain protein 4 (BRD4) as a central epigenetic regulator in neuropsychiatric and neurodegenerative disorders
Bromodomain-containing protein 4 (BRD4), a member of the bromodomain and extra-terminal (BET) family, is a central epigenetic regulator that links histone acetylation-dependent chromatin remodelling to transcriptional control. Through recognition of acetylated lysine residues and recruitment of transcriptional machinery, it is increasingly recognised as a critical regulator of neuronal and glial functions, influencing synaptic plasticity, neuroinflammation, learning, memory, and behavioural...
Necroptosis in Down Syndrome
Necroptosis is a form of controlled cell death implicated in neuronal loss observed in neurodegenerative diseases such as Alzheimer's disease. Down syndrome (DS) is also characterized by the presence of neuronal cell loss, but the underlying mechanisms remain unclear. Brain tissue from a mouse model of DS, Ts65dn mice, and subjects with DS were assessed for levels of necroptosis markers including receptor-interactive protein kinase 1 and 3, necroptosis executor mixed lineage kinase domain-like...
Methionine-supplemented longevity diet increases growth hormone, GLP-1, and FGF21; reduces frailty; and promotes healthspan
Southern European countries have some of the highest life expectancies in the world, yet they display relatively high frailty. We examined different diets to identify compositions that promote both healthspan and strength in mice. The western and ketogenic diets increased fat mass and frailty and increased either cholesterol or insulin resistance, whereas a low-protein longevity diet, modeling the traditional Mediterranean and Okinawan diets but supplemented with methionine (LDMM), reduced fat...
Calorie restriction and exercise differentially regulate AMP-activated protein kinase across subcellular compartments in skeletal muscle from older male rats
AMP-activated protein kinase (AMPK) is a crucial energy sensor that regulates a wide range of important processes in skeletal muscle. AMPK is present in several subcellular compartments (including the cytosol, nucleus, and mitochondria). However, the influence of physiologically relevant interventions on AMPK's localization in skeletal muscle is not well understood, especially during older age. Accordingly, this study examined AMPK signaling in skeletal muscle from aged male rats...
YIF1A activates mTORC1 signaling to promote cellular senescence
The mechanistic target of rapamycin complex 1 (mTORC1) serves as a central metabolic hub that integrates nutrient signals and orchestrates cellular metabolism to regulate many fundamental cell processes. While mTORC1 activation is known to occur both on lysosomal membranes and at the Golgi apparatus in response to environmental cues, the molecular mechanisms governing its Golgi-associated activation remain poorly understood. In this study, we identified YIF1A as a novel Golgi-localized regulator...
Trifunctional electrocatalyst with accurate surface reconstruction for zinc-air batteries and water electrolyzers
Exploiting cost-effective trifunctional electrocatalysts toward oxygen evolution reaction, hydrogen evolution reaction and oxygen reduction reaction is important for sustainable energy conversion and storage devices yet challenging. Here, we report a single-phase trifunctional electrocatalyst Sr(2)CoRuO(6-δ) with well-defined super-exchange double perovskite structure, which can efficiently catalyze oxygen evolution, hydrogen evolution and oxygen reduction under alkaline conditions. As an air...
