Core-Excited Molecules by Resonant Intense X-Ray Pulses Involving Electron-Rotation Coupling

It has been reported that electron-rotation coupling plays a significant role in diatomic nuclear dynamics induced by intense VUV pulses [Phys. Rev. A 102(2020) 033114;Phys. Rev. Res. 2(2020) 043348]. As a further step, we present here investigations of the electron-rotation coupling effect in the presence of Auger decay channel for core-excited molecules, based on theoretical modeling of the total electron yield(TEY), resonant Auger scattering(RAS) and x-ray absorption spectra(XAS) for two showcases of CO and CH^(+) molecules excited by resonant intense x-ray pulses. The Wigner D-functions and the universal transition dipole operators are introduced to include the electron-rotation coupling for the core-excitation process. It is shown that with the pulse intensity up to 10^(16) W/cm^(2), no sufficient influence of the electron-rotation coupling on the TEY and RAS spectra can be observed. This can be explained by a suppression of the induced electron-rotation dynamics due to the fast Auger decay channel, which does not allow for effective Rabi cycling even at extreme field intensities,contrary to transitions in optical or VUV range. For the case of XAS, however, relative errors of about 10% and 30% are observed for the case of CO and CH^(+), respectively, when the electron-rotation coupling is neglected.It is concluded that conventional treatment of the photoexcitation, neglecting the electron-rotation coupling,can be safely and efficiently employed to study dynamics at the x-ray transitions by means of electron emission spectroscopy, yet the approximation breaks down for nonlinear processes as stimulated emission, especially for systems with light atoms.

Objective:To determine the effects of Chinese medicine(CM)involving triple rehabilitation therapy on the progression of knee osteoarthritis(KOA).Methods:A total of 722 patients recruited from 38 community health service centers located in China from March 2013 to March 2017 were randomly divided into treatment and control groups equally,using a cluster randomization design.Health education combined with CM involving triple rehabilitation therapy for KOA(electro-acupuncture,Chinese medicinal herb fumigating-washing,and traditional exercises)was administered in the treatment group while conventional rehabilitation therapy(physical factor therapy,joint movement training,and muscle strength training)was administered in the control group.Patients with a visual analog scale(VAS)scores>A were treated with dispersible meloxicam tablets(7.5 mg,once daily).The Lequesne index scores,VAS scores,range of motion(ROM),lower limb muscle strength,knee joint circumference,quantitative scores of KOA symptoms,and the short-form 36 item health survey questionnaire(SF-36)scores were measured for each patient at 5 checkpoints(before treatment,at the 2nd week and the 4th week during the 4-week treatment period,at 1 month and 3 months after end of treatment),and adverse reactions were observed also.Results:A total of 696 patients completed the entire process,with 351 in the treatment group and 345 in the control group.At all treatment checkpoints,the treatment group demonstrated better outcomes than the control group with regard to the total Lequesne index scores,effective rate and improvement rate of the total Lequesne index scores,VAS scores,lower limb muscle strength,knee circumference,quantitative scores of KOA symptoms,and SF-36 scores as well(P<0.05 or P<0.01).No adverse reactions were encountered in this study.Conclusions:CM involving triple rehabilitation therapy can alleviate KOA-related pain and swelling,improve lower limb muscle strength,promote flexion and activity of the knee and improve the quality of life in patients undergoing KOA.It is suitable for patients with early or mid-stage KOA.(Registration No.ChiCTR-TRC-12002538)

Visible-near infrared ultra-broadband polarization-independent metamaterial perfect absorber involving phase-change materials

We numerically demonstrate a novel ultra-broadband polarization-independent metamaterial perfect absorber in the visible and near-infrared region involving the phase-change material Ge_2Sb_2Te_5(GST).The novel perfect absorber scheme consists of an array of high-index strong-absorbance GST square resonators separated from a continuous Au substrate by a low-index lossless dielectric layer(silica)and a high-index GST planar cavity.Three absorption peaks with the maximal absorbance up to 99.94% are achieved,owing to the excitation of plasmon-like dipolar or quadrupole resonances from the high-index GST resonators and cavity resonances generated by the GST planar cavity.The intensities and positions of the absorption peaks show strong dependence on structural parameters.A heat transfer model is used to investigate the temporal variation of temperature within the GST region.The results show that the temperature of amorphous GST can reach up to 433 K of the phase transition temperature from room temperature in just 0.37 ns with a relatively low incident light intensity of 1.11×10~8W∕m^2,due to the enhanced ultra-broadband light absorbance through strong plasmon resonances and cavity resonance in the absorber.The study suggests a feasible means to lower the power requirements for photonic devices based on a thermal phase change via engineering ultra-broadband light absorbers.

Disentangling brain PrP^(C)proteoforms and their roles in physiology and disease

The cellular prion protein(PrPC),a cell surface glycoprotein of 209 amino acids,has been considerably studied over the decades mainly due to its critical involvement in transmissible spongiform encephalopathies,or prion diseases.Indeed,it is the misfolding and aggregation of PrPC into pathological assemblies-named PrPSc-that constitute prions,the agents causing these unusual neurodegenerative diseases affecting humans and animals(Prusiner,1982).Furthermore,increasing evidence support its relevance also in other neurodegenerative diseases(NDDs),such as Alzheimer’s and Parkinson’s diseases(Corbett et al.,2020).

Multifunctional glycolipids as multi-targeting therapeutics for neural regeneration

Many patients with neurodegenerative diseases,such as Alzheimer’s(AD)and Parkinson’s(PD)diseases suffer from disease progression without any satisfying clinical intervention,likely due to our lack of knowledge on how normal aging impacts the pathogenic mechanisms of these debilitating diseases.A growing body of literature has emerged in recent years that clearly demonstrates the involvement of glycolipids in the protein-oligomerization of neurodegenerative disorders.We hypothesize that changes in glycolipids composition are a common mechanism underlying the shift from healthy brain aging to the neuropathological processes of neurodegenerative diseases.

An early scoring system to predict mechanical ventilation for botulism: a single-center-based study

BACKGROUND: Early identification of patients requiring ventilator support will be beneficial for the outcomes of botulism. The present study aimed to establish a new scoring system to predict mechanical ventilation(MV) for botulism patients.METHODS: A single-center retrospective study was conducted to identify risk factors associated with MV in botulism patients from 2007 to 2022. Univariate analysis and multivariate logistic regression analysis were used to screen out risk factors for constructing a prognostic scoring system. The area under the receiver operating characteristic(ROC) curve was calculated.RESULTS: A total of 153 patients with botulism(66 males and 87 females, with an average age of 43 years) were included. Of these, 49 patients(32.0%) required MV, including 21(13.7%) with invasive ventilation and 28(18.3%) with non-invasive ventilation. Multivariate analysis revealed that botulinum toxin type, pneumonia, incubation period, degree of hypoxia, and severity of muscle involvement were independent risk factors for MV. These risk factors were incorporated into a multivariate logistic regression analysis to establish a prognostic scoring system. Each risk factor was scored by allocating a weight based on its regression coefficient and rounded to whole numbers for practical utilization([botulinum toxin type A: 1], [pneumonia: 2], [incubation period ≤1 day: 2], [hypoxia <90%: 2], [severity of muscle involvement: grade Ⅱ, 3;gradeⅢ, 7;grade IV, 11]). The scoring system achieved an area under the ROC curve of 0.82(95% CI 0.75–0.89, P<0.001). At the optimal threshold of 9, the scoring system achieved a sensitivity of 83.7% and a specificity of 70.2%.CONCLUSION: Our study identified botulinum toxin type, pneumonia, incubation period, degree of hypoxia, and severity of muscle involvement as independent risk factors for MV in botulism patients. A score ≥9 in our scoring system is associated with a higher likelihood of requiring MV in botulism patients. This scoring system needs to be validated externally before it can be applied in clinical settings.

Development and validation of a 6-gene signature derived from RNA modification-associated genes for the diagnosis of Acute Stanford Type A Aortic Dissection

Background Acute Stanford Type A Aortic Dissection(ATAAD)is a critical medical emergency characterized by significant morbidity and mortality.This study aims to identify specific gene expression patterns and RNA modification associated with ATAAD.Methods The GSE153434 dataset was obtained from the Gene Expression Omnibus(GEO)database.Differential expression analysis was conducted to identify differential expression genes(DEGs)associated with ATAAD.To validate the involvement of RNA modification in ATAAD,RNA modification-related genes(M6A,M1A,M5C,APA,A-to-I)were acquired from GeneCards,following by Least Absolute Shrinkage and Selection Operator(LASSO)regression analysis.A gene prediction signature consisting of key genes was established,and Real-time PCR was used to validate the gene expression in clinical samples.The patients were then divided into high and low-risk groups,and subsequent enrichment analysis,including Gene Ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG),Gene Set Enrichment Analysis(GSEA),Gene Set Variation Analysis(GSVA),and assessments of immune infiltration.A co-expression network analysis(WGCNA)was performed to explore gene-phenotype relationships and identify key genes.Results A total of 45 RNA modification genes were acquired.Six gene signatures(YTHDC1,WTAP,CFI,ADARB1,ADARB2,TET3)were developed for ATAAD diagnosis and risk stratification.Enrichment analysis suggested the potential involvement of inflammation and extracellular matrix pathways in the progression of ATAAD.The incorporation of pertinent genes from the GSE147026 dataset into the six-gene signature further validated the model's effectiveness.A significant upregulation in WTAP,ADARB2,and TET3 expression,whereas YTHDC1 exhibited a noteworthy downregulation in the ATAAD group.Conclusion Six-gene signature could serve as an efficient model for predicting the diagnosis of ATAAD.

An unusual cause of myocardial infarction in an elderly man

Cardiac involvement in eosinophilic granulomatosis with polyangiitis (EPGA) is increasingly recognized,but it is unusual to be the initial presentation.We report a case of vasculitic myocardial infarction (MI) and cardiogenic shock in an elderly man caused by EPGA.A 73-year-old man presented with acute chest pain radiating to back for two days.He has a history of asthma and allergic rhinitis for more than ten years well controlled by inhaled corticosteroid.The electrocardiogram showed sinus rhythm,right bundle-branch block and anterolateral ST-segment depression.He had elevated troponin T of 548 ng/L (reference:<14 ng/L),creatine kinase of 454 IU/L (reference:39–308 IU/L)。

Causal effect of psoriasis on aortic valve stenosis:a two-sample Mendelian randomization study

Background Epidemiological studies have suggested a potential connection between psoriasis and an increased risk of aortic valve stenosis(AS),though the impact of psoriasis on AS progression remains uncertain.The study aims to investigate the causal relationship between psoriasis and AS using Mendelian randomization(MR)analysis,as well as to uncover potential mechanisms underlying this association.Methods A two-sample MR analysis was conducted using publicly available summary statistics from genome-wide association studies(GWAS)of psoriasis and AS.Cis-eQTL and significant genes were identified for each causal single-nucleotide polymorphisms(SNPs),followed by pathway enrichment and protein-protein interaction(PPI)analysis for functional evaluation.Hub genes were pinpointed by Cytospace.The transcriptional profile of AS population was acquired,and interconnected genes networks were clustered using Molecular Complex Detection(MCODE).Results Our results demonstrate a significant causal relationship between psoriasis and AS,with a genetic predisposition to psoriasis associated with a higher AS risk(odds ratio:1.46).Pathway and PPI analyses unveiled 15 hub genes,including HLA-C,HLA-B,ISG15,IFIT3,and MX2,along with immune-related pathways linking psoriasis and AS.Moreover,the transcriptional profiling of the AS database highlighted the significant involvement of adaptive immune cells in AS development.Notably,among the 15 hub genes,ISG15,MX2,OAS3,OASL,IFI6,and EPSTI1 exhibited higher expression in the AS population.Conclusion Our study provides compelling evidence supporting a causal relationship between psoriasis and AS.Furthermore,the identified hub genes and immune-related pathways may play an important role in the development of both diseases.

Brain-wide activation involved in 15 mA transcranial alternating current stimulation in patients with first-episode major depressive disorder

Background Although 15 mA transcranial alternating current stimulation(tACS)has a therapeutic effect on depression,the activations of brain structures in humans accounting for this tACS configuration remain largely unknown.Aims To investigate which intracranial brain structures are engaged in the tACS at 77.5 Hz and 15 mA,delivered via the forehead and the mastoid electrodes in the human brain.Methods Actual human head models were built using the magnetic resonance imagings of eight outpatient volunteers with drug-naïve,first-episode major depressive disorder and then used to perform the electric field distributions with SimNIBS software.Results The electric field distributions of the sagittal,coronal and axial planes showed that the bilateral frontal lobes,bilateral temporal lobes,hippocampus,cingulate,hypothalamus,thalamus,amygdala,cerebellum and brainstem were visibly stimulated by the 15 mA tACS procedure.Conclusions Brain-wide activation,including the cortex,subcortical structures,cerebellum and brainstem,is involved in the 15 mA tACS intervention for first-episode major depressive disorder.Our results indicate that the simultaneous involvement of multiple brain regions is a possible mechanism for its effectiveness in reducing depressive symptoms.
