Circadian Amplitude Regulation via FBXW7-Targeted REV-ERBα Degradation.

Defects in circadian rhythm influence physiology and behavior with implications for the treatment of sleep disorders, metabolic disease, and cancer. Although core regulatory components of clock rhythmicity have been defined, insight into the mechanisms underpinning amplitude is limited. Here, we show that REV-ERBα, a core inhibitory component of clock transcription, is targeted for ubiquitination and subsequent degradation by the F-box protein FBXW7. By relieving REV-ERBα-dependent repression, FBXW7 provides an unrecognized mechanism for enhancing the amplitude of clock gene transcription. Cyclin-dependent kinase 1 (CDK1)-mediated phosphorylation of REV-ERBα is necessary for FBXW7 recognition. Moreover, targeted hepatic disruption of FBXW7 alters circadian expression of core clock genes and perturbs whole-body lipid and glucose levels. This CDK1-FBXW7 pathway controlling REV-ERBα repression defines an unexpected molecular mechanism for re-engaging the positive transcriptional arm of the clock, as well as a potential route to manipulate clock amplitude via small molecule CDK1 inhibition.

Isogenic human iPSC Parkinson's model shows nitrosative stress-induced dysfunction in MEF2-PGC1α transcription.

Parkinson's disease (PD) is characterized by loss of A9 dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc). An association has been reported between PD and exposure to mitochondrial toxins, including environmental pesticides paraquat, maneb, and rotenone. Here, using a robust, patient-derived stem cell model of PD allowing comparison of A53T α-synuclein (α-syn) mutant cells and isogenic mutation-corrected controls, we identify mitochondrial toxin-induced perturbations in A53T α-syn A9 DA neurons (hNs). We report a pathway whereby basal and toxin-induced nitrosative/oxidative stress results in S-nitrosylation of transcription factor MEF2C in A53T hNs compared to corrected controls. This redox reaction inhibits the MEF2C-PGC1α transcriptional network, contributing to mitochondrial dysfunction and apoptotic cell death. Our data provide mechanistic insight into gene-environmental interaction (GxE) in the pathogenesis of PD. Furthermore, using small-molecule high-throughput screening, we identify the MEF2C-PGC1α pathway as a therapeutic target to combat PD.

Distinct virtual histology of grey matter atrophy in four neuroinflammatory diseases.

Gray matter (GM) atrophies were observed in multiple sclerosis, neuromyelitis optica spectrum disorders (both anti-aquaporin-4 antibody-positive [AQP4+], and -negative [AQP4-] subtypes NMOSD), and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD). Revealing the pathogenesis of brain atrophy in these disorders would help their differential diagnosis and guide therapeutic strategies. To determine the neurobiological underpinnings of GM atrophies in multiple sclerosis, AQP4+ NMOSD, AQP4- NMOSD, and MOGAD, we conducted a virtual histology analysis that links T1-weighted image derived GM atrophy and gene expression using a multicenter cohort of 324 patients with multiple sclerosis, 197 patients with AQP4+ NMOSD, 75 patients with AQP4- NMOSD, 47 patients with MOGAD, and 2,169 healthy controls (HCs). First, interregional GM atrophy profiles across the cortical and subcortical regions were determined by Cohen's d between patients with multiple sclerosis, AQP4+ NMOSD, AQP4- NMOSD, MOGAD and HCs. Then, the GM atrophy profiles were spatially correlated with the gene expressions extracted from the Allen Human Brain Atlas, respectively. Finally, we explored the virtual histology of clinical feature relevant GM atrophy by subgroup analysis that stratified by physical disability, disease duration, number of relapses, lesion burden, and cognitive function. Multiple sclerosis showed severe widespread GM atrophy pattern, mainly involving subcortical nuclei and brainstem. AQP4+ NMOSD showed obvious widespread GM atrophy pattern, predominately located in occipital cortex as well as cerebellum. AQP4- NMOSD showed mild widespread GM atrophy pattern, mainly located in frontal and parietal cortices. MOGAD showed GM atrophy mainly involving the frontal and temporal cortices. High expression of genes specific to microglia, astrocytes, oligodendrocytes, and endothelial cells in multiple sclerosis, S1 pyramidal cells in AQP4+ NMOSD, as well as S1 and CA1 pyramidal cells in MOGAD had spatial correlations with GM atrophy profiles were observed, while no atrophy profile related gene expression was found in AQP4- NMOSD. Virtual histology of clinical feature relevant GM atrophy mainly pointed to the shared neuronal and endothelial cells among the four neuroinflammatory diseases. The unique underlying virtual histology patterns were microglia, astrocytes, and oligodendrocytes for multiple sclerosis; astrocytes for AQP4+ NMOSD; and oligodendrocytes for MOGAD. Neuronal and endothelial cells were shared potential targets across these neuroinflammatory diseases. These findings might help their differential diagnosis and optimal therapeutic strategies.

S-nitrosylated TDP-43 triggers aggregation, cell-to-cell spread, and neurotoxicity in hiPSCs and in vivo models of ALS/FTD.

Rare genetic mutations result in aggregation and spreading of cognate proteins in neurodegenerative disorders; however, in the absence of mutation (i.e., in the vast majority of "sporadic" cases), mechanisms for protein misfolding/aggregation remain largely unknown. Here, we show environmentally induced nitrosative stress triggers protein aggregation and cell-to-cell spread. In patient brains with amyotrophic lateral sclerosis (ALS)/frontotemporal dementia (FTD), aggregation of the RNA-binding protein TDP-43 constitutes a major component of aberrant cytoplasmic inclusions. We identify a pathological signaling cascade whereby reactive nitrogen species cause S-nitrosylation of TDP-43 (forming SNO-TDP-43) to facilitate disulfide linkage and consequent TDP-43 aggregation. Similar pathological SNO-TDP-43 levels occur in postmortem human FTD/ALS brains and in cell-based models, including human-induced pluripotent stem cell (hiPSC)-derived neurons. Aggregated TDP-43 triggers additional nitrosative stress, representing positive feed forward leading to further SNO-TDP-43 formation and disulfide-linked oligomerization/aggregation. Critically, we show that these redox reactions facilitate cell spreading in vivo and interfere with the TDP-43 RNA-binding activity, affecting SNMT1 and phospho-(p)CREB levels, thus contributing to neuronal damage in ALS/FTD disorders.

The Impact of high-performance work system perceived by medical staff on job satisfaction: the mediating role of self-efficacy.

As the mainstay of healthcare, the job satisfaction of medical staff deserves attention. This study aimed to explore the correlation between the perception of the high-performance work system (P-HPWS) and job satisfaction of medical staff in public hospitals and to further investigate the mediating effect of self-efficacy. From November 2019 to January 2020, a cross-sectional survey on working doctors and nurses was conducted in five tertiary public hospitals in China. A total of 520 participants were surveyed. The P-HPWS, job satisfaction, and self-efficacy were assessed using the 25-item self-administered scale, six-item job satisfaction questionnaire, and the General Self-Efficacy Scale, respectively. Linear regression and mediation effects models were used to identify the associations between primary variables. The results showed a significant positive correlation between P-HPWS and job satisfaction (P < 0.01), while self-efficacy played a mediating role between P-HPWS and job satisfaction. This finding reveals the benefits of improving employees' P-HPWS and self-efficacy on their job satisfaction, and that hospitals can improve their management systems by implementing and refining HPWS.

Cerebellar connectome alterations and associated genetic signatures in multiple sclerosis and neuromyelitis optica spectrum disorder.

BACKGROUND: The cerebellum plays key roles in the pathology of multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD), but the way in which these conditions affect how the cerebellum communicates with the rest of the brain (its connectome) and associated genetic correlates remains largely unknown. METHODS: Combining multimodal MRI data from 208 MS patients, 200 NMOSD patients and 228 healthy controls and brain-wide transcriptional data, this study characterized convergent and divergent alterations in within-cerebellar and cerebello-cerebral morphological and functional connectivity in MS and NMOSD, and further explored the association between the connectivity alterations and gene expression profiles. RESULTS: Despite numerous common alterations in the two conditions, diagnosis-specific increases in cerebellar morphological connectivity were found in MS within the cerebellar secondary motor module, and in NMOSD between cerebellar primary motor module and cerebral motor- and sensory-related areas. Both diseases also exhibited decreased functional connectivity between cerebellar motor modules and cerebral association cortices with MS-specific decreases within cerebellar secondary motor module and NMOSD-specific decreases between cerebellar motor modules and cerebral limbic and default-mode regions. Transcriptional data explained > 37.5% variance of the cerebellar functional alterations in MS with the most correlated genes enriched in signaling and ion transport-related processes and preferentially located in excitatory and inhibitory neurons. For NMOSD, similar results were found but with the most correlated genes also preferentially located in astrocytes and microglia. Finally, we showed that cerebellar connectivity can help distinguish the three groups from each other with morphological connectivity as predominant features for differentiating the patients from controls while functional connectivity for discriminating the two diseases. CONCLUSIONS: We demonstrate convergent and divergent cerebellar connectome alterations and associated transcriptomic signatures between MS and NMOSD, providing insight into shared and unique neurobiological mechanisms underlying these two diseases.

Brain age gap in neuromyelitis optica spectrum disorders and multiple sclerosis.

OBJECTIVE: To evaluate the clinical significance of deep learning-derived brain age prediction in neuromyelitis optica spectrum disorder (NMOSD) relative to relapsing-remitting multiple sclerosis (RRMS). METHODS: This cohort study used data retrospectively collected from 6 tertiary neurological centres in China between 2009 and 2018. In total, 199 patients with NMOSD and 200 patients with RRMS were studied alongside 269 healthy controls. Clinical follow-up was available in 85 patients with NMOSD and 124 patients with RRMS (mean duration NMOSD=5.8±1.9 (1.9-9.9) years, RRMS=5.2±1.7 (1.5-9.2) years). Deep learning was used to learn 'brain age' from MRI scans in the healthy controls and estimate the brain age gap (BAG) in patients. RESULTS: A significantly higher BAG was found in the NMOSD (5.4±8.2 years) and RRMS (13.0±14.7 years) groups compared with healthy controls. A higher baseline disability score and advanced brain volume loss were associated with increased BAG in both patient groups. A longer disease duration was associated with increased BAG in RRMS. BAG significantly predicted Expanded Disability Status Scale worsening in patients with NMOSD and RRMS. CONCLUSIONS: There is a clear BAG in NMOSD, although smaller than in RRMS. The BAG is a clinically relevant MRI marker in NMOSD and RRMS.

Spencerozyma pingqiaoensis sp. nov., a yeast species isolated from the external surface of rice leaves in China.

Four strains (NYNU 178247, NYNU 178251, DMKU-PAL160 and DMKU-PAL137) representing a novel yeast species were isolated from the external surfaces of rice and pineapple leaves collected in China and Thailand. Phylogenetic analysis based on the concatenated sequences of the internal transcribed spacer (ITS) regions and the D1/D2 domains of the large subunit rRNA gene revealed that the novel species belonged to the genus Spencerozyma. The D1/D2 sequence of the novel species differed from its closest relative, Spencerozyma acididurans SYSU-17T, by 3.2 % sequence divergence. The species also differed from Spencerozyma crocea CBS 2029T and Spencerozyma siamensis DMKU13-2T, by 3.0-6.9 % sequence divergence in the D1/D2 sequences out of 592 bp. In the ITS regions, the novel species displayed 19.8-29.2% sequence divergence from S. acididurans SYSU-17T, S. crocea CBS 2029T and S. siamensis DMKU13-2T out of 655 bp. Furthermore, the novel species could also be differentiated from the closely related species by some physiological characteristics. The species name of Spencerozyma pingqiaoensis sp. nov. (Holotype CBS 15238, Mycobank MB 844734) is proposed to accommodate these four strains.

Effects of Yinzhihuang on Alleviating Cyclosporine A-Induced Cholestatic Liver Injury via Farnesoid X Receptor-Mediated Regulation of Transporters and Enzymes in Vitro and in Vivo.

Yinzhihuang (YZH), a traditional Chinese medicine prescription, was widely used to treat cholestasis. Cholestatic liver injury limited the use of the immunosuppressive drug cyclosporine A (CsA) in preventing organ rejection after solid organ transplantation. Clinical evidences suggested that YZH could enhance bile acids and bilirubin clearance, providing a potential therapeutic strategy against CsA-induced cholestasis. Nevertheless, it remains unclear whether YZH can effectively alleviate CsA-induced cholestatic liver injury, as well as the molecular mechanisms responsible for its hepatoprotective effects. The purpose of the present study was to investigate the hepatoprotective effects of YZH on CsA-induced cholestatic liver injury and explore its molecular mechanisms in vivo and vitro. The results demonstrated that YZH significantly improved the CsA-induced cholestatic liver injury and reduced the level of liver function markers in serum of Sprague-Dawley (SD) rats. Targeted protein and gene analysis indicated that YZH increased bile acids and bilirubin efflux into bile through the regulation of multidrug resistance-associated protein 2 (Mrp2), bile salt export pump (Bsep), sodium taurocholate cotransporting polypeptide (Ntcp) and organic anion transporting polypeptide 2 (Oatp2) transport systems, as well as upstream nuclear receptors farnesoid X receptor (Fxr). Moreover, YZH modulated enzymes involved in bile acids synthesis and bilirubin metabolism including Cyp family 7 subfamily A member 1 (Cyp7a1) and uridine 5'-diphosphate (UDP) glucuronosyltransferase family 1 member A1 (Ugt1a1). Furthermore, the active components geniposidic acid, baicalin and chlorogenic acid exerted regulated metabolic enzymes and transporters in LO2 cells. In conclusion, YZH may prevent CsA-induced cholestasis by regulating the transport systems, metabolic enzymes, and upstream nuclear receptors Fxr to restore bile acid and bilirubin homeostasis. These findings highlight the potential of YZH as a therapeutic intervention for CsA-induced cholestasis and open avenues for further research into its clinical applications.

Non-Pharmacological Interventions in Patients With Heart Failure With Reduced Ejection Fraction: A Systematic Review and Network Meta-Analysis.

OBJECTIVE: To determine the effectiveness of non-pharmacologic interventions and the additional benefits of their combination in patients with heart failure with reduced ejection fraction (HFrEF). DATA SOURCES: We searched PubMed, Embase, and the Cochrane Clinical Trials Register from the date of database inception to April 22, 2023. STUDY SELECTION: Randomized controlled trials involving non-pharmacologic interventions conducted in patients with HFrEF were included. DATA EXTRACTION: Data were extracted by 2 independent reviewers based on a pre-tested data extraction form. The quality of evidence was assessed using the Cochrane Risk of Bias tool and the Grading of Recommendations Assessment, Development, and Evaluation method. DATA SYNTHESIS: A total of 82 eligible studies (4574 participants) were included. We performed a random-effects model within a Bayesian framework to calculate weighted mean differences (WMDs) and 95% credibility intervals. High or moderate certainty evidence indicated that high-intensity aerobic interval training (HIAIT) was best on improving 6-minute walk distance (6MWD; 68.55 m [36.41, 100.47]) and left ventricular ejection fraction (6.28% [3.88, 8.77]), while high-intensity aerobic continuous training (HIACT) is best on improving peak oxygen consumption (Peak VO2; 3.48 mL/kg•min [2.84, 4.12]), quality of life (QOL; -17.26 [-29.99, -7.80]), resting heart rate (-8.20 bpm [-13.32, -3.05]), and N-terminal pro-B-type natriuretic peptide (-600.96 pg/mL [-902.93, -404.52]). Moderate certainty evidence supported the effectiveness of inspiratory muscle training to improve peak oxygen consumption and functional electrical stimulation to improve QOL. Moderate-intensity aerobic continuous training (MIACT) plus moderate-intensity resistance training (MIRT) had additional benefits in Peak VO2, 6MWD, and QOL. This review did not provide a comprehensive evaluation of adverse events. CONCLUSIONS: Both HIAIT and HIACT are the most effective single non-pharmacologic interventions for HFrEF. MIACT plus MIRT had additional benefits in improving peak oxygen consumption, 6MWD, and QOL.

Opportunities and challenges: mesenchymal stem cells in the treatment of multiple sclerosis.

Multiple sclerosis (MS) was once considered an untreatable disease. Through years of research, many drugs have been discovered and are widely used for the treatment of MS. However, the current treatment can only alleviate the clinical symptoms of MS and has serious side effects. Mesenchymal stem cells (MSCs) provide neuroprotection by migrating to injured tissues, suppressing inflammation, and fostering neuronal repair. Therefore, MSCs therapy holds great promise for MS treatment. This review aimed to assess the feasibility and safety of use of MSCs in MS treatment as well as its development prospect in clinical treatment by analysing the existing clinical studies.

The Effects of Silicone Tube Intubation During Endoscopic Dacryocystorhinostomy in Patients With Acute Dacryocystitis With Acquired Skin Fistulization.

OBJECTIVE: This study aimed to determine the silicone tube intubation requirement for endoscopic dacryocystorhinostomy (En-DCR) in patients with acute dacryocystitis (AD) with acquired skin fistulization. METHODS: Between September 2012 and October 2020, patients with AD and acquired skin fistulization undergoing En-DCR at the Eye Hospital of Wenzhou Medical University were randomized into treatment groups in which silicone tube intubation was carried out or not (groups A and B, respectively). All patients with skin fistulae present for 1+ months at En-DCR underwent fistulectomy. Operative success was assessed at 12 months post En-DCR in both treatment groups. Multiple logistic analyses were performed to assess for influencing factors on surgical success. RESULTS: This study evaluated 94 patients for whom complete postoperative data were available, including 45 in group A and 44 in group B. Overall, 15 patients underwent fistulectomy and En-DCR simultaneously (8 from group A; 7 from group B ). At 12-month follow-up, anatomic and functional success rates were higher for patients in group A (93.3%, 86.7%) relative to those in group B (77.3%, 68.2%) (P<0.05). Intranasal ostium obstruction caused lacrimal passage reconstruction failure in group A. In contrast, intranasal ostium and canalicular obstruction caused it in patients in group B. No significant variations in operation success rates across groups were seen when group B cases with canalicular obstruction were eliminated from the analyses (P=0.070, >0.05). Multiple logistic regression analysis showed operative success was significantly influenced by fistulectomy (OR: 1.641, P<0.05) and intubation (OR: -1.559, P<0.05). CONCLUSION: These findings imply that in patients with AD with skin fistulization undergoing En-DCR, intraoperative intubation is linked with a lower incidence of canalicular obstruction and positive outcomes. Accordingly, intraoperative intubation should be performed when operating on patients with AD with skin fistulization.

Regulatory emotional self-efficacy as a mediator between high-performance work system perceived by nurses on their job burnout: a cross-sectional study.

The purpose of this study was to explore the correlation between the perception of high performance work system (P-HPWS) and job burnout of nurses, further to detect the mediating effect of regulatory emotional self-efficacy (RES). From November 2019 to January 2020, a cross-sectional survey on working nurses was conducted in 5 hospitals in Lanzhou, China. A total of 1266 nurses were investigated. Demographics and perception of high performance work systems, job burnout, and RES were collected. The data were statistically processed using correlation analysis, multiple linear regression analysis, and a test of mediated moderation. The P-HPWS was significantly negatively correlated with job burnout (P < 0.01). The RES played a mediating effect between the perception of HPWS and job burnout. The results support the important role of P-HPWS in the remission of job burnout, and the hospital can improve its management by implementing and perfecting the HPWS.Abbreviations: P-HPWS: Perceived high-performance work system; RES: Regulatory emotional self-efficacy; POS: Perceived self-efficacy in expressing positive emotions; ANG: Perceived self-efficacy in managing anger/irritation; DES: Perceived self-efficacy in managing despondency/distress.

Lactobacillus paracasei TK1501 fermented soybeans alleviate dextran sulfate sodium-induced colitis by regulating intestinal cell function.

BACKGROUND: Probiotic food provide health benefits by regulating intestinal floras via live bacteria, but the shelf life is short and the preservation condition is demanding due to the bacteria being fragile. Owing to these problems, we have tried to find a fermented food that is helpful for inflammatory bowel disease treatment but independent of live bacteria. In addition, the mechanisms of fermented food were investigated. Dextran sulfate sodium was used to model inflammatory bowel disease in mice, and Lactobacillus paracasei TK1501 fermented soybeans and their metabolites were used to treat inflammatory bowel disease. RESULTS: In this study, TK1501 fermented soybean alleviated colitis. However, the efficacy was associated with bacterial metabolites but not live or dead bacteria. Compositional analysis of soybean before and after fermentation shows that soy carbohydrates were used for bacteria growth and produced functional substances. Further, we display the main active ingredient was lipoteichoic acid and peptidoglycan, because lipoteichoic acid reduced the colonic macrophage and peptidoglycan may increase the mucin-2 expression. A cell experiment displayed that lipoteichoic acid could enhance the phagocytosis of macrophages. CONCLUSION: In general, TK1501 fermented soybean alleviating colitis is dependent on metabolites of TK1501, particularly lipoteichoic acid and peptidoglycan. The fermented food may have a long shelf life and lax storage condition. © 2023 Society of Chemical Industry.

Achieving Molecular Recognition of Structural Analogues in Surface-Enhanced Raman Spectroscopy: Inducing Charge and Geometry Complementarity to Mimic Molecular Docking.

Molecular recognition of complex isomeric biomolecules remains challenging in surface-enhanced Raman scattering (SERS) spectroscopy due to their small Raman cross-sections and/or poor surface affinities. To date, the use of molecular probes has achieved excellent molecular sensitivities but still suffers from poor spectral specificity. Here, we induce "charge and geometry complementarity" between probe and analyte as a key strategy to achieve high spectral specificity for effective SERS molecular recognition of structural analogues. We employ 4-mercaptopyridine (MPY) as the probe, and chondroitin sulfate (CS) disaccharides with isomeric sulfation patterns as our proof-of-concept study. Our experimental and in silico studies reveal that "charge and geometry complementarity" between MPY's binding pocket and the CS sulfation patterns drives the formation of site-specific, multidentate interactions at the respective CS isomerism sites, which "locks" each CS in its analogue-specific complex geometry, akin to molecular docking events. Leveraging the resultant spectral fingerprints, we achieve > 97 % classification accuracy for 4 CSs and 5 potential structural interferences, as well as attain multiplex CS quantification with < 3 % prediction error. These insights could enable practical SERS differentiation of biologically important isomers to meet the burgeoning demand for fast-responding applications across various fields such as biodiagnostics, food and environmental surveillance.

Structural and functional hippocampal alterations in Multiple sclerosis and neuromyelitis optica spectrum disorder.

BACKGROUND: Hippocampal involvement may differ between multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD). OBJECTIVE: To investigate the morphometric, diffusion and functional alterations in hippocampus in MS and NMOSD and the clinical significance. METHODS: A total of 752 participants including 236 MS, 236 NMOSD and 280 healthy controls (HC) were included in this retrospective multi-center study. The hippocampus and subfield volumes, fractional anisotropy (FA) and mean diffusivity (MD), amplitude of low frequency fluctuation (ALFF) and degree centrality (DC) were analyzed, and their associations with clinical variables were investigated. RESULTS: The hippocampus showed significantly lower volume, FA and greater MD in MS compared to NMOSD and HC (p < 0.05), while no abnormal ALFF or DC was identified in any group. Hippocampal subfields were affected in both diseases, though subiculum, presubiculum and fimbria showed significantly lower volume only in MS (p < 0.05). Significant correlations between diffusion alterations, several subfield volumes and clinical variables were observed in both diseases, especially in MS (R = -0.444 to 0.498, p < 0.05). FA and MD showed fair discriminative power between MS and HC, NMOSD and HC (AUC > 0.7). CONCLUSIONS: Hippocampal atrophy and diffusion abnormalities were identified in MS and NMOSD, partly explaining how clinical disability and cognitive impairment are differentially affected.

Clinical Heterogeneity in Acute Symptomatic Seizures due to Autoimmune Encephalitis Related to GAD65 Antibodies.

INTRODUCTION: This study aimed to explore the diversity and clinical features of acute symptomatic seizures due to autoimmune encephalitis related to anti-glutamate decarboxylase (GAD) 65 antibodies. METHODS: Clinical data of a series of 6 patients positive for anti-GAD65 antibodies were retrospectively analyzed. RESULTS: Five of the patients were male and 1 was a female, with a median age of 44.1 years (range 18-70 years). Seizure forms were varied in 6 patients when they were admitted to the hospital: 3 cases of seizures only and 3 accompanied by other symptoms, such as mental disorder, cognitive impairment, cerebellar ataxia, and ocular movement disorder. Three patients (50%) had coexisting systemic autoimmune diseases, including diabetes mellitus, vitiligo, and hyperthyroidism. Five patients (83%) had abnormal brain MRI findings. They were all treated by immunotherapy, 5 of 6 patients improved significantly but relapsed after withdrawing methylprednisolone, and 1 patient got deteriorated. None of them were diagnosed with tumors. CONCLUSIONS: Clinical features of acute symptomatic seizures related to GAD65 antibodies are diverse, and early and continuous immunotherapy is necessary for patients.

Surface-Enhanced Raman Scattering (SERS) Taster: A Machine-Learning-Driven Multireceptor Platform for Multiplex Profiling of Wine Flavors.

Integrating machine learning with surface-enhanced Raman scattering (SERS) accelerates the development of practical sensing devices. Such integration, in combination with direct detection or indirect analyte capturing strategies, is key to achieving high predictive accuracies even in complex matrices. However, in-depth understanding of spectral variations arising from specific chemical interactions is essential to prevent model overfit. Herein, we design a machine-learning-driven "SERS taster" to simultaneously harness useful vibrational information from multiple receptors for enhanced multiplex profiling of five wine flavor molecules at parts-per-million levels. Our receptors employ numerous noncovalent interactions to capture chemical functionalities within flavor molecules. By strategically combining all receptor-flavor SERS spectra, we construct comprehensive "SERS superprofiles" for predictive analytics using chemometrics. We elucidate crucial molecular-level interactions in flavor identification and further demonstrate the differentiation of primary, secondary, and tertiary alcohol functionalities. Our SERS taster also achieves perfect accuracies in multiplex flavor quantification in an artificial wine matrix.

Comparison of life quality in older adults living in traditional family versus nursing home: a systematic review and meta-analysis.

To assess and compare the QoL of the older people dwelling in traditional family versus nursing home/institution. A comprehensive literature search was performed on 10 January 2018 to identify studies that investigated the QoL of older adults dwelling in family versus nursing home settings. Analyses were run using random-effects meta-analyses. A total of six cross-sectional studies with 1623 people were included. The quality of included studies was moderate. Meta-analysis showed that compared with nursing home support, the family support could significantly improve the physical health (6 studies, SMD = 0.50, 95%CI: 0.32-0.68, p < 0.05), mental status (6 studies, SMD = 0.45, 95%CI: 0.26-0.65, p < 0.05), and social relationship (5 studies, SMD = 0.51, 95%CI: 0.19-0.83, p < 0.05). Traditional family support model demonstrated a significant improvement in the physical health, psychological status and social relationships among older adults. The conclusions were driven by cross-sectional studies, Larger, adequately powered RCTs are required to confirm our finding.

Effective co-treatment of synthetic acid mine drainage and domestic sewage using multi-unit passive treatment system supplemented with silage fermentation broth as carbon source.

A multi-unit passive treatment system was constructed for co-treatment of synthetic acid mine drainage (AMD) and domestic sewage supplemented with silage fermentation broth as carbon source. AMD and domestic sewage mixing pretreatment (unit 1) improved influent quality with pH increase, metals removal and nutrients supplement. The generated metal-rich sludge in unit 1 retained the metals (69.95% of Fe, 97.36% of Cu, 96.53% of Cd, 72.52% of Zn, and 8.59% of Mn) of influent prior to entering subsequent bioreactors. Silage fermentation broth performed well to promote bacterial sulfate reduction in sulfate reducing bioreactor system (unit 2). Residual metals (Mn) and organic/nutrient pollutants were further polished in surface-flow aerobic wetland (unit 3), where relatively high pH (7.4-8.6), aerobic condition, potential Mn-oxidizing bacteria, limestone layer and low concentrations of Fe(II) (0.04-3.5 mg/L) favored the efficient removal of Mn. After 210-day continuous flow-through experiment, this passive treatment system demonstrated the efficient performance, increasing pH from 2.5 to 8.0 with removal of metals (99%), sulfate and organic/nutrient pollutants. Diverse sulfate reducing bacteria including complete organic oxidizers (e.g. Desulfobacter) and incomplete organic oxidizers (e.g. Desulfovibrio) promoted sulfate reduction and organic/nutrient pollutants removal. Ammonia oxidizing bacteria (e.g. Nitrosomonas) and nitrite oxidizing bacteria (e.g. unidentified_Nitrospiraceae) were the potential nitrifiers for ammonia removal. Collaboration of anaerobic denitrifiers (e.g. Denitratisoma) and potential heterotrophic nitrifying and aerobic denitrifiers (HN-AD) achieved effective nitrate removal. This multi-unit treatment system with domestic sewage and silage fermentation broth as stimulation substrates provided an attractive option for AMD treatment.
