Rice bran oil rescues cognitive decline in D-galactose-induced aging mice by inhibiting Aβ accumulation and Tau hyperphosphorylation induced oxidative stress and neuroinflammation

Alzheimer's disease (AD) is a neurodegenerative disorder associated with brain aging， and the accumulation of amyloid-beta (Aβ) and hyperphosphorylated Tau proteins are key pathological features. Currently， drugs for the treatment of AD are mainly single-targeted， but the complex pathogenesis of AD makes it difficult to achieve the desired results. Therefore， the development of multitargeted therapies is crucial for future interventions. Rice bran oil (RBO) has been recognized as an edible oil with several health benefits， but its effects on AD caused by brain aging remain underexplored. In this study， the effects of RBO on memory dysfunction in D-galactose (D-gal) mice and its molecular mechanisms were investigated via in vivo and in silico methods from the perspective of AD pathologies. Our results suggested that compounds in RBO could modulate the activities of β-site amyloid precursor protein cleaving enzyme 1 (BACE1)， mitogen-activated protein kinase 3 (MAPK3)， matrix metalloproteinase 3 (MMP3)， and intercellular adhesion molecule 1 (ICAM1)， leading to inhibition of Aβ accumulation and Tau protein hyper-phosphorylation. Moreover， RBO reduced Aβ-induced oxidative stress by inhibiting the activity of mouse double minute 2 homolog (MDM2) and cyclic adenosine monophosphate response element binding protein binding protein (CREBBP)， and attenuated neuroinflammation by inhibiting the activity of nitric oxide synthase 2 (NOS2) and reducing Aβ accumulation and Tau protein hyperphosphorylation. Additionally， α-linolenic acid in RBO exhibited inhibitory effects on D-gal-induced apoptosis in PC12 cells through modulation of NOS2， MDM2， ICAM1， and phospho-extracellular signal-regulated kinase 1/2 (p-ERK1/2). Similarly， stigmastanol inhibited apoptosis in D-gal-induced PC12 cells through the regulation of NOS2. Thus， RBO can be considered as a potential functional food to attenuate AD owing to its multicomponent and multitarget effects.

Bioinspired Multifunctional Self-Sensing Actuated Gradient Hydrogel for Soft-Hard Robot Remote Interaction

Nano-Micro Letters 2024年第4期16卷 139-152页

The development of bioinspired gradient hydrogels with self-sensing actuated capabilities for remote interaction with soft-hard robots remains a challenging endeavor. Here, we propose a novel multifunctional self-sensing actuated gradient hydrogel that combines ultrafast actuation and high sensitivity for remote interaction with robotic hand. The gradient network structure, achieved through a wettability difference method involving the rapid precipitation of MoO_(2) nanosheets, introduces hydrophilic disparities between two sides within hydrogel. This distinctive approach bestows the hydrogel with ultrafast thermo-responsive actuation(21° s^(-1)) and enhanced photothermal efficiency(increase by 3.7 ℃ s^(-1) under 808 nm near-infrared). Moreover, the local cross-linking of sodium alginate with Ca^(2+) endows the hydrogel with programmable deformability and information display capabilities. Additionally, the hydrogel exhibits high sensitivity(gauge factor 3.94 within a wide strain range of 600%), fast response times(140 ms) and good cycling stability. Leveraging these exceptional properties, we incorporate the hydrogel into various soft actuators, including soft gripper, artificial iris, and bioinspired jellyfish, as well as wearable electronics capable of precise human motion and physiological signal detection. Furthermore, through the synergistic combination of remarkable actuation and sensitivity, we realize a self-sensing touch bioinspired tongue. Notably, by employing quantitative analysis of actuation-sensing, we realize remote interaction between soft-hard robot via the Internet of Things. The multifunctional self-sensing actuated gradient hydrogel presented in this study provides a new insight for advanced somatosensory materials, self-feedback intelligent soft robots and human–machine interactions.

Cyanidin 3-O-β-galactoside from black chokeberry exerts neuroprotective effects in mice fed with high-fat/high-sugar diet through regulating glucose metabolism

Unhealthy diets are associated with various diseases that can disrupt brain energy metabolism， which significantly increased the risk of cognitive impairment and chronic neurodegenerative diseases. Early intervention with nutritional supplements may have long-lasting positive effects on diet-related glucose metabolism and potentially mediate the progression of neurodegeneration in middle-aged and elderly people. We previously reported that cyanidin 3-O-β-galactoside (Cy3Gal)， an anthocyanin from black chokeberry (Aronia melanocarpa (Michx.) Elliott)， alleviated cognitive impairment in aging mice through regulating brain energy metabolism. However， it remains unclear whether Cy3Gal can also exert beneficial effects in mice fed with a high-fat/high-sugar diet. Here we revealed that Cy3Gal treatment conserved the health of neurons and synapses， as well as cognitive function of mice. Furthermore， we observed that Cy3Gal effectively improved glucose uptake and metabolism of skeletal muscle by enhancing glycolysis both in vivo and in vitro models， which is essential for maintaining a stable glucose supply to the brain. Additionally， Cy3Gal significantly increased the levels of glucose-derived tricarboxylic acid cycle intermediates in the mice brain (P < 0.05)， and regulated the activities of mitochondrial respiratory chain complexes (P < 0.01). The positive influence on peripheral and brain bioenergetics explained how the Cy3Gal exerted neuroprotective effect. In conclusion， our study illustrated that early dietary intervention of Cy3Gal had significant advantages in terms of neuroprotection and cognition under the challenge of HFHS diet-induced glucose metabolism disorder.
