Image_1_Magnetic resonance-guided laser interstitial thermal therapy vs. stereoelectroencephalography-guided radiofrequency thermocoagulation in epilepsy patients with focal cortical dysplasia: a systematic review and meta-analysis.TIF
BackgroundMagnetic resonance-guided laser interstitial thermal therapy (MRgLiTT) and stereoelectroencephalography-guided radiofrequency thermocoagulation (SEEG-RFTC) are two effective, minimally invasive treatments for epilepsy with focal cortical dysplasia (FCD). The purpose of this study is to conduct a meta-analysis to evaluate and compare the efficacy and safety of these two therapies in epilepsy patients with FCD.MethodsWe searched PubMed, Embase, Cochrane, and other databases for articles published before March 2023. The primary objective was to compare the effectiveness and complications of MRgLiTT and SEEG-RFTC in epilepsy patients with FCD. The second objective was to determine which method provides a better prognosis for specific subgroup patients.ResultsAccording to the inclusion and exclusion criteria, 18 studies were included, comprising 270 FCD patients including 37 patients from 6 MRgLiTT studies and 233 from 12 SEEG-RFTC studies. There were no significant differences between MRgLiTT and SEEG-RFTC groups in the seizure-freedom rate (59%, 95% CI 44–74%; 52%, 95% CI 47–57%, P = 0.86) and the rate of ≥50% seizure-reduction of FCD (90%, 95% CI 80–100%; 90%, 95% CI 86–94%, P = 0.42). Both methods had low complication rates (17.1%, 28/159) and long-term complication (2.5%, 4/159) rate, with no significant difference between them (P = 0.17).ConclusionBoth MRgLiTT and SEEG-RFTC are safe and minimally invasive treatments for patients with FCD. They have comparable performance in terms of postoperative seizure-freedom rates in patients with FCD, and both can be used as treatment options for patients with FCD. Our study found that SEEG-RFTC had a better therapeutic effect in the FCD2b subgroup.</p

Lead-Free Semiconducting Organic–Inorganic Hybrid Perovskite with Mixed Organic Cations
Hybrid perovskites with mixed organic cations have recently
received
extensive focus from researchers for their structural tunability,
enhanced performance, and stability. However, because there are certain
requirements for the size of different organic cations to form hybrid
perovskites with mixed organic cations, reports on hybrid perovskites
that can contain both phosphonium and ammonium cations have been rare.
Here, we report an organic–inorganic hybrid perovskite (Me3PCH2CH2CH3)2(CH3CH2CH2NH3)Sb2Br9 (1) with [Me3PCH2CH2CH3]+ cations and [CH3CH2CH2NH3]+ cations. Compound 1 exhibits a reversible phase transition at 371.3/353.2 K.
Compared with the organic–inorganic hybrid perovskites only
with [Me3PCH2CH2CH3]+ cations or [CH3CH2CH2NH3]+ cations, the phase transition temperature of
the organic–inorganic hybrid perovskite formed by mixing [Me3PCH2CH2CH3]+ cations
and [CH3CH2CH2NH3]+ cations is significantly increased, and the thermal stability
is improved. Structural analysis shows the disorder of [CH3CH2CH2NH3]+ cations and
the twisting motion of [Me3PCH2CH2CH3]+ cations and the inorganic skeleton are
the major reasons for the phase transition of 1 at high
temperatures. Furthermore, 1 possesses semiconductor
properties with an optical band gap of 2.945 eV. This discovery will
shed light on exploring more excellent functional perovskite materials
with mixed organic cations
Influence of Pd(II) Adsorption on High-Temperature Ferroelastic Phase Transition in (2-Amino-2-thiazolinium)PbBr<sub>3</sub>
Ferroelastic materials have received special attention
because
of their great promise for mechanical switches, piezoelectric sensors,
and data storage applications. Here, we report a novel ferroelastic
semiconducting hybrid organic–inorganic perovskite (C3H7N2S)PbBr3 (1) [(C3H7N2S)+ is 2-amino-2-thiazolinium]
with a ferroelastic phase transition at 395 K and an optical band
gap of 3.43 eV. 1 has a one-dimensional BaNiO3-type structure and undergoes a high-temperature ferroelastic phase
transition with an Aizu notation of mmmF2/m. Meanwhile, 1 exhibits dielectric switch
near the phase transition temperature. By introducing the thioether
group, the motion of the molecules or ions of 1 is hindered
after the sorption of Pd(II) metal ions, which leads to the disappearance
of the high-temperature ferroelastic phase transition and dielectric
switch. This is the first reported ferroelastic semiconductor material
with Pd(II) adsorption property, by studying the influence of Pd(II)
adsorption on high-temperature ferroelastic phase transition, it may
be enlightening to further uncover the mechanism of phase transition
or the origin of ferroelasticity, which represents an important step
toward multifunctional applications of lead-hybrid perovskite-based
ferroelastic materials
DataSheet1_Mendelian randomization analysis identified tumor necrosis factor as being associated with severe COVID-19.docx
Background: Observational studies have shown that anti-tumor necrosis factor (TNF) therapy may be beneficial for patients with coronavirus disease 2019 (COVID-19). Nevertheless, because of the methodological restrictions of traditional observational studies, it is a challenge to make causal inferences. This study involved a two-sample Mendelian randomization analysis to investigate the causal link between nine TNFs and COVID-19 severity using publicly released genome-wide association study summary statistics.Methods: Summary statistics for nine TNFs (21,758 cases) were obtained from a large-scale genome-wide association study. Correlation data between single-nucleotide polymorphisms and severe COVID-19 (18,152 cases vs. 1,145,546 controls) were collected from the COVID-19 host genetics initiative. The causal estimate was calculated by inverse variance-weighted (IVW), MR–Egger, and weighted median methods. Sensitivity tests were conducted to assess the validity of the causal relationship.Results: Genetically predicted TNF receptor superfamily member 6 (FAS) positively correlated with the severity of COVID-19 (IVW, odds ratio = 1.10, 95% confidence interval = 1.01–1.19, p = 0.026), whereas TNF receptor superfamily member 5 (CD40) was protective against severe COVID-19 (IVW, odds ratio = 0.92, 95% confidence interval = 0.87–0.97, p = 0.002).Conclusion: Genetic evidence from this study supports that the increased expression of FAS is associated with the risk of severe COVID-19 and that CD40 may have a potential protective effect against COVID-19.</p
Mapping the Knowledge Domain of Corrosion Inhibition Studies of Ionic Liquids
Ionic liquids have received much attention in metal corrosion
inhibition
due to their unique properties of nontoxicity, low contamination,
and high efficiency in corrosion inhibition. To fully understand the
current status and latest progress of research in corrosion inhibition,
we analyzed the literature using a systematic bibliometric method
and visualization technology. The relevant studies specifically included
co-occurrence analysis, cluster analysis, cocitation analysis, and
keyword burst detection analysis. The results show that Asian countries,
led by China, constitute the central research force in this ionic
liquid corrosion inhibition field. Materials science, applied physics,
and applied chemistry were the core disciplines in this research field,
and the Journal of Molecular Liquids, Corrosion Science, Electrochim
Acta, and Industrial & Engineering Chemistry
Research were the core journals. The hot research topics
in this field had been roughly divided into five timelines, representing
five research topics: ionic liquid, solution, corrosion resistance,
corrosion inhibitor, and film. The ionic liquid corrosion inhibition
field has many research directions and a wide range of frontier branches.
Among them, electrochemistry, molecular simulation, and electrolyte
solutions have become the frontier of ionic liquid corrosion inhibition

DataSheet1_Exploring the molecular mechanism of Gan Shuang granules for the treatment of non-alcoholic steatohepatitis using network pharmacology, molecular docking, and experimental verification.docx
Background: With the gradual increase in prevalence in recent years, non-alcoholic steatohepatitis (NASH) has become one of the significant health problems that urgently needs to be addressed worldwide. GanShuang Granules (GSG) is derived from the classical Chinese formula Xiaoyao San and mainly used in the clinical treatment of chronic liver diseases.Objective: In this study, we aim to gain a deeper insight into the inhibiting effects of GSG on non-alcoholic fatty liver disease (NAFLD) rats and preliminarily elucidate the underlying intervention mechanisms.Methods: First, High performance liquid chromatography (UHPLC-Q/Orbitrap-MS/MS) was used for the active compounds prediction in GSG. Then the data was mapped to mzCloud database. The targets corresponding to GSG compounds were collected from public databases, along with disease genes for NAFLD. The core targets and molecular mechanisms of GSG for NAFLD treatment were predicted by protein-protein interaction (PPI) network, Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) functional enrichment analyses. Molecular docking of the core target-component interactions was simulated using AutoDock Vina software. The effect of GSG on NASH rats was evaluated by pathological staining and analysis of various index results. Finally, the candidate targets were further validated by ELISA and western blot (WB) analyses.Results: Combining UHPLC-Q/Orbitrap-MS/MS data analysis and public database data, a total of 346 cross-targets were obtained, corresponding to 81 compounds. The subnetwork with an MCODE score of 53.623 is a potential core target group for this study. GO and KEGG enrichment analyses showed that the targets of GSG in NAFLD were mostly related to oxidative stress, the NF-κB signaling pathway, and the apoptosis signaling pathway. By integrating the results of network pharmacology analysis, the core objectives of this study mainly include AKT1, CASP9, TNF, and CASP8. The core ingredients are related to resveratrol and fisetin. The molecular docking results indicated key binding activity between AKT1-fisetin, AKT1-Resveratrol, and CASP8-fisetin. Moreover, GSG could improve the inflammatory status and restore the abnormal lipid accumulation of NAFLD/NASH liver, and these levels are further verified by pathological staining and detection of related indicators. Mechanistically, GSG could regulate protein expression levels in the liver for P65, p-P65, IKB, p-IKB, IKK, caspase-3, -8, -9, and cytochrome C, etc. It reflects the inhibitory effect of GSG on the NF-κB/IκB signaling pathway.Conclusion: Our results suggested that GSG demonstrated therapeutic effects on NAFLD/NASH rats, and these may be mainly reflected in the inhibitory effects on the NF-κB/IκB signaling pathway and its downstream inflammation and apoptosis signals.</p
Table_2_Necroptosis-associated long noncoding RNAs can predict prognosis and differentiate between cold and hot tumors in ovarian cancer.docx
ObjectiveThe mortality rate of ovarian cancer (OC) is the highest among all gynecologic cancers. To predict the prognosis and the efficacy of immunotherapy, we identified new biomarkers.MethodsThe Cancer Genome Atlas (TCGA) and the Genotype-Tissue Expression Project (GTEx) databases were used to extract ovarian cancer transcriptomes. By performing the co-expression analysis, we identified necroptosis-associated long noncoding RNAs (lncRNAs). We used the least absolute shrinkage and selection operator (LASSO) to build the risk model. The qRT-PCR assay was conducted to confirm the differential expression of lncRNAs in the ovarian cancer cell line SK-OV-3. Gene Set Enrichment Analysis, Kaplan-Meier analysis, and the nomogram were used to determine the lncRNAs model. Additionally, the risk model was estimated to evaluate the efficacy of immunotherapy and chemotherapy. We classified necroptosis-associated IncRNAs into two clusters to distinguish between cold and hot tumors.ResultsThe model was constructed using six necroptosis-associated lncRNAs. The calibration plots from the model showed good consistency with the prognostic predictions. The overall survival of one, three, and five-year areas under the ROC curve (AUC) was 0.691, 0.678, and 0.691, respectively. There were significant differences in the IC50 between the risk groups, which could serve as a guide to systemic treatment. The results of the qRT-PCR assay showed that AL928654.1, AL133371.2, AC007991.4, and LINC00996 were significantly higher in the SK-OV-3 cell line than in the Iose-80 cell line (P ConclusionNecroptosis-associated lncRNAs are reliable predictors of prognosis and can provide a treatment strategy by screening for hot tumors.</p
