Moreover, the adsorption process was both spontaneous and thermodynamically favourable with physical adsorption and multilinear intraparticle diffusion being the predominant mechanisms of the whole process. HPST treatment at 25 °C with 80% ethanol as the desorption solvent most noticeably enhanced the adsorption/desorption of flavonoids and contributed to the highest recovery of TFC, Total Phenolic Content (TPC), and antioxidant capacity in addition to a 5-8-fold reduction in total sugar and acid contents when compared with NS treatment. Moreover, HPLC analysis revealed that the content of nine out of thirteen phenolic compounds from the HPST treatment was the highest, and the individual flavonoids content increased by 2-3-fold compared with the other treatments. Our analyses suggested that ultrasound can be employed as a practical approach to intensify the adsorption and desorption of functional compounds in BFP. Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease with the loss of upper motor neurons in the cortex and lower motor neurons in the brain stem and spinal cord regressively. The vast majority of ALS cases have no familial history are apparently sporadic (SALS), making the modeling of SALS essential to the development of ALS therapeutics. Therefore, human induced pluripotent stem cell (iPSC) from peripheral blood mononuclear cells of a 64-year-old SALS patient were produced using a virus-free protocol and characterized using standard validate methods. This generated iPSC line could be useful to reveal SALS mechanisms and screen drug development. The role of Neurochondrin (NCDN) in humans is not well understood. Mice with a conditional Ncdn knock-out show epileptic seizures, depressive-like behaviours and impaired spatial learning. Using CRISPR/Cas9, we generated a Neurochondrin deficient human iPSC line KICRi002-A-3 carrying a homozygous 752 bp deletion / 2 bp insertion in the NCDN gene. The iPSC line maintained a normal 46,XY karyotype, expressed pluripotency markers and exhibited capability to differentiate into the three germ layers in vitro. Off-target editing was excluded and Neurochondrin expression was not detectable. The iPSC line offers a valuable resource to study the role of Neurochondrin during human neurogenesis. INTRODUCTION To determine whether vitamin B12 level at Parkinson's disease (PD) diagnosis predicts time to develop dementia. METHODS We utilized a population-based cohort of Parkinsonism patients to examine the relationship between serum vitamin B12 at the time of PD diagnosis and dementia risk. Receiver operating curves were calculated for vitamin B12 cutoffs maximizing sensitivity and specificity for determining who developed dementia. Time from Parkinsonism diagnosis to dementia, death, or censoring was calculated utilizing Kaplan-Meier analysis and Cox-proportional hazard models. RESULTS PD patients who did not develop dementia had higher baseline levels of vitamin B12 at PD diagnosis (648.5 ng/L vs 452 ng/L, p  less then  0.05) than those who developed dementia. Dementia risk was significantly lower in the 3rd tertile compared with 2nd tertile and trended towards significance compared to the 1st tertile. Each 100 unit increase in vitamin B12 level had a hazard ratio of 0.31 (95% CI 0.44-0.95) for future dementia (p  less then  0.05). Vitamin B12 cutoff of less then 587 ng/L was 87% sensitive and 70% specific (AUC 0.79, 95% CI 0.60-0.98) distinguishing patients with dementia. PD patients with vitamin B12 levels less then 587 ng/L were 5.4 times more likely to develop dementia, with 50% having dementia within 5 years of PD diagnosis compared with 11% in those with a vitamin B12 level of ≥587 ng/L (p  less then  0.05). CONCLUSION Higher levels of serum vitamin B12 at PD diagnosis correlate with lower risk of future dementia. The role of vitamin B12 in the development of dementia among PD patients deserves further evaluation. Research on ethnic/racial disparities in sleep in the United States finds minorities to have shorter self-reported and actigraphy-recorded sleep duration and poorer sleep quality. Disparities in mental health mirror disparities in sleep with ethnic/racial minorities reporting higher prevalence and more severe struggles. This review focuses on recent research in sleep and mental health disparities and considers ethnic/racial discrimination as an important third variable that may link these two domains of disparities research. For example, research has found discrimination to mediate ethnic/racial disparities in sleep; at the same time, sleep has been observed to mediate the link between discrimination and mental health. The review concludes with the importance of considering ethnicity/race and accompanying sociodemographic, environmental, and behavioral influences on sleep and mental health research. selleck kinase inhibitor Sleep and circadian disturbances in bipolar disorder are common and persistent within and between illness episodes. Insomnia, hypersomnia, reduced need for sleep, sleep schedule variability and circadian rhythm disorders are frequently observed. In this article, recent research is reviewed suggesting that the presence of sleep disturbance is associated with functional impairment, interacts with other physical and environmental systems (e.g. physical activity, light exposure), and may attenuate response to treatment. Established and emerging treatments for various sleep disturbances are reviewed, with emphasis on applications for light therapy and adapted cognitive behavioral therapy. There remains a critical need to understand the co-occurrence of various sleep disturbances, develop, and refine treatment approaches (especially for hypersomnia/long sleep duration) and adapt wearable and smartphone technologies to aid assessment and intervention. Functional changes of nucleus pulposus cells (NPCs) are considered to be the initiating factors of intervertebral disc degeneration (IDD). In this study, we investigated whether circular RNA homo sapiens (hsa)_circ_001653 (circ_001653) could bind to microRNA-486-3p (miR-486-3p) to regulate the biological properties of NPCs and the synthesis of extracellular matrix (ECM) in IDD. Initially, circ_001653 was highly expressed in isolated NPCs and degenerative NP tissues in close relation to the severity of IDD. To evaluate the effects of circ_001653 on cellular processes, we performed experiments in vitro and in vivo with altered expression of circ_001653 and miR-486-3p. An increased expression of circ_001653 in the NPCs and the degenerative NP tissues was directly associated with elevated apoptosis and an imbalance between anabolic and catabolic factors of the ECM. miR-486-3p regulated NPC proliferation and inhibited the expression of CEMIP, the cell migration-inducing hyaluronan binding protein. circ_001653 regulated miR-486-3p expression, functioning in NPCs to upregulate CEMIP, whereas circ_001653 silencing alleviated IDD in the mouse model.
