The effects of anastomoses between anterior and posterior circulation on postoperative prognosis of patients with moyamoya disease.

BACKGROUND: Moyamoya disease (MMD) is a chronic ischemic cerebrovascular disease. Collateral circulation in MMD has emerged as a research focus. Our aims were to assess the impact of anastomoses between the anterior and posterior circulations on the prognosis of MMD patients. METHODS: We reviewed the preoperative digital subtraction angiography images of patients with MMD who underwent revascularization surgery at our hospital between March 2014 and May 2020 and divided the patients into two groups: those with anastomoses (PtoA group) and those without anastomoses (non-PtoA group). The differences in follow-up (more than 6 months) collateral vessel establishment (Matsushima grade) and the modified Rankin Scale (mRS) were compared between the two groups as well as between the patients with different degrees of anastomoses. The early complications following revascularization were also compared between the two groups. RESULTS: This study included 104 patients with MMD, of which 38 were non-PtoA and 66 were PtoA. There were no significant differences in Matsushima score (P = 0.252) and mRS score (P = 0.066) between the two groups. In addition, Matsushima score (P = 0.243) and mRS score (P = 0.360) did not differ significantly between patients with different degrees of anastomoses. However, the non-PtoA group had a significantly higher rate of cerebral hyperperfusion syndrome (CHS) than the PtoA group (34.2% vs 16.7%, P = 0.041). CONCLUSION: MMD patients without anastomoses between anterior and posterior circulations preoperatively should be vigilant of the occurrence of CHS in the early stages after revascularization.

Role of single-cell ferroptosis regulation in intercellular communication and skin cutaneous melanoma progression and immunotherapy.

BACKGROUND: The involvement of ferroptosis in the pathogenesis and progression of various cancers has been well established. However, limited studies have investigated the role of ferroptosis-mediated tumor microenvironment (TME) in skin cutaneous melanoma (SKCM). METHODS: By leveraging single-cell RNA sequencing data, the nonnegative matrix factorization (NMF) approach was employed to comprehensively characterize and identify distinct gene signatures within ferroptosis-associated TME cell clusters. Prognostic and treatment response analyses were conducted using both bulk datasets and external cancer cohort to evaluate the clinical implications of TME clusters. RESULTS: This NMF-based analysis successfully delineated fibroblasts, macrophages, T cells, and B cells into multiple clusters, enabling the identification of unique gene expression patterns and the annotation of distinct TME clusters. Furthermore, pseudotime trajectories, enrichment analysis, cellular communication analysis, and gene regulatory network analysis collectively demonstrated significant intercellular communication between key TME cell clusters, thereby influencing tumor cell development through diverse mechanisms. Importantly, our bulk RNA-seq analysis revealed the prognostic significance of ferroptosis-mediated TME cell clusters in SKCM patients. Moreover, our analysis of immune checkpoint blockade highlighted the crucial role of TME cell clusters in tumor immunotherapy, facilitating the discovery of potential immunotherapeutic targets. CONCLUSIONS: In conclusion, this pioneering study employing NMF-based analysis unravels the intricate cellular communication mediated by ferroptosis within the TME and its profound implications for the pathogenesis and progression of SKCM. We provide compelling evidence for the prognostic value of ferroptosis-regulated TME cell clusters in SKCM, as well as their potential as targets for immunotherapy.

Lowering Contact Resistances of Two-Dimensional Semiconductors by Memristive Forming.

Two-dimensional semiconductors have great potential for beyond-silicon electronics. However, because of the lack of controllable doping methods, Fermi level pinning, and van der Waals (vdW) gaps at the metal-semiconductor interfaces, these devices exhibit high electrical contact resistances, restricting their practical applications. Here, we report a general contact-resistance-lowering strategy by constructing vertical metal-semiconductor-metal memristor structures at the contact regions and setting them into a nonvolatile low-resistance state through a memristive forming process. Through this, we reduce the contact resistances of MoS2 field-effect transistors (FETs) by at least one order of magnitude and improve the on-state current densities of MoTe2 FETs by about two orders of magnitude. We also demonstrate that this strategy is applicable to other two-dimensional semiconductors, including MoSe2, WS2, and WSe2, and a variety of contact metals, including Au, Cu, Ni, and Pd. The good stability and universality indicate the great potential for technological applications.

Formononetin Inhibits Mast Cell Degranulation to Ameliorate Compound 48/80-Induced Pseudoallergic Reactions.

Formononetin (FNT) is a plant-derived isoflavone natural product with anti-inflammatory, antioxidant, and anti-allergic properties. We showed previously that FNT inhibits immunoglobulin E (IgE)-dependent mast cell (MC) activation, but the effect of FNT on IgE-independent MC activation is yet unknown. Our aim was to investigate the effects and possible mechanisms of action of FNT on IgE-independent MC activation and pseudoallergic inflammation. We studied the effects of FNT on MC degranulation in vitro with a cell culture model using compound C48/80 to stimulate either mouse bone marrow-derived mast cells (BMMCs) or RBL-2H3 cells. We subsequently measured ß-hexosaminase and histamine release, the expression of inflammatory factors, cell morphological changes, and changes in NF-κB signaling. We also studied the effects of FNT in several in vivo murine models of allergic reaction: C48/80-mediated passive cutaneous anaphylaxis (PCA), active systemic anaphylaxis (ASA), and 2,4-dinitrobenzene (DNCB)-induced atopic dermatitis (AD). The results showed that FNT inhibited IgE-independent degranulation of MCs, evaluated by a decrease in the release of ß-hexosaminase and histamine and a decreased expression of inflammatory factors. Additionally, FNT reduced cytomorphological elongation and F-actin reorganization and attenuated NF-κB p65 phosphorylation and NF-κB-dependent promoter activity. Moreover, the administration of FNT alleviated pseudoallergic responses in vivo in mouse models of C48/80-stimulated PCA and ASA, and DNCB-induced AD. In conclusion, we suggest that FNT may be a novel anti-allergic drug with great potential to alleviate pseudoallergic responses via the inhibition of IgE-independent MC degranulation and NF-κB signaling.

Machine learning and single-cell transcriptome profiling reveal regulation of fibroblast activation through THBS2/TGFß1/P-Smad2/3 signalling pathway in hypertrophic scar.

Hypertrophic scar (HS) is a chronic inflammatory skin disorder characterized by excessive deposition of extracellular matrix, and the mechanisms underlying their formation remain poorly understood. We analysed scRNA-seq data from samples of normal skin and HS. Using the hdWGCNA method, key gene modules of fibroblasts in HS were identified. Non-negative matrix factorization was employed to perform subtype analysis of HS patients using these gene modules. Multiple machine learning algorithms were applied to screen and validate accurate gene signatures for identifying and predicting HS, and a convolutional neural network (CNN) based on deep learning was established and validated. Quantitative reverse transcription-polymerase chain reaction and western blotting were performed to measure mRNA and protein expression. Immunofluorescence was used for gene localization analysis, and biological features were assessed through CCK8 and wound healing assay. Single-cell sequencing revealed distinct subpopulations of fibroblasts in HS. HdWGCNA identified key gene characteristics of this population, and pseudotime analysis was conducted to investigate gene variation during fibroblast differentiation. By employing various machine learning algorithms, the gene range was narrowed down to three key genes. A CNN was trained using the expression of these key genes and immune cell infiltration, enabling diagnosis and prediction of HS. Functional experiments demonstrated that THBS2 is associated with fibroblast proliferation and migration in HS and affects the formation and development of HS through the TGFß1/P-Smad2/3 pathway. Our study identifies unique fibroblast subpopulations closely associated with HS and provides biomarkers for the diagnosis and treatment of HS.

IRE1α/NOX4 signaling pathway mediates ROS-dependent activation of hepatic stellate cells in NaAsO2 -induced liver fibrosis.

Liver fibrosis is a severe health problem worldwide, and it is characterized by the activation of hepatic stellate cells (HSCs) and excessive deposition of collagen. Prolonged arsenic exposure can induce HSCs activation and liver fibrosis. In the present study, the results showed that chronic NaAsO2 ingestion could result in liver fibrosis and oxidative stress in Sprague-Dawley rats, along with representative collagen deposition and HSCs activation. In addition, the inositol-requiring enzyme 1α (IRE1α)-endoplasmic reticulum (ER)-stress pathway was activated, and the activity of nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX4) was upregulated in rat livers. Simultaneously, the excessive production of reactive oxygen species (ROS) could induce HSCs activation, and NOX4 played an important role in generating ROS in vitro. Moreover, ER stress occurred with HSCs activation at the same time under NaAsO2 exposure, and during ER stress, the IRE1α pathway was responsible for NOX4 activation. Therefore, inhibition of IRE1α activation could attenuate the HSCs activation induced by NaAsO2 . In conclusion, the present study manifested that inorganic arsenic exposure could activate HSCs through IRE1α/NOX4-mediated ROS generation.

Cathepsin B-Activated Fluorescent and Photoacoustic Imaging of Tumor.

Early diagnosis is crucial to the treatment of cancer. Cathepsin B (CTB) plays an important role in numerous cancers, which is a promising biomarker for early diagnosis of cancer. It is necessary to exploit new probes for visualization of CTB in vivo. Fluorescent/photoacoustic (FL/PA) imaging is a powerful tool for in vivo study which possesses both excellent sensitivity and spatial resolution. To our knowledge, there has been no FL/PA probe to image CTB in vitro or in vivo. Therefore, we developed two CTB-activated FL/PA probes HCy-Cit-Val and HCy-Gly-Leu-Phe-Gly, which could successfully monitor CTB activity in vivo. Both two probes had excellent sensitivity and selectivity in vitro. Cell imaging showed that HCy-Cit-Val or HCy-Gly-Leu-Phe-Gly could image endogenous CTB in lysosome with 6.8-fold or 5.1-fold enhancement of the FL signal and 5.8-fold or 3.4-fold enhancement of the PA signal compared to their inhibitor contrast groups. Tumor imaging in vivo further confirmed the good applicability of these two probes to monitor CTB activity with high sensitivity and spatial resolution. Moreover, the property of HCy-Cit-Val is superior to HCy-Gly-Leu-Phe-Gly due to the higher catalytic efficiency of CTB toward HCy-Cit-Val than HCy-Gly-Leu-Phe-Gly. We envision that our FL/PA probe HCy-Cit-Val will be suitable for clinical early diagnosis of CTB-related cancer in the near future.

NLRP3 inflammasome blocked the glycolytic pathway via targeting to PKLR in arsenic-induced hepatic insulin resistance.

Arsenic exposure is related to insulin resistance (IR). However, the underlying mechanism is still uncertain. NOD-like receptors containing pyrin domain 3 (NLRP3) inflammasome is a key driving factor of IR. We found that NaAsO2 caused hepatic IR, activated NLRP3 inflammasome, and inhibited glycolysis pathway in vivo. We also found that tricarboxylic acid cycle (TCA cycle) was inhibited, and the content of hepatic lactate was upregulated with the treatment of arsenic. Consistent with these findings, we found that NLRP3 inflammasome and glycolysis were involved in the development of IR in L-02 cells. Besides, inhibiting NLRP3 inflammasome upregulated aerobic glycolysis and inhibited anaerobic glycolysis. Moreover, we demonstrated that NLRP3 inflammasome could bind to pyruvate kinase, liver and RBC (PKLR). Simultaneously, insulin signaling rather than NLRP3 inflammasome activation was altered by overexpressing PKLR. In summary, after treatment with NaAsO2, NLRP3 inflammasome blocked the glycolytic pathway via binding to PKLR, which in turn caused hepatic IR. This study shed new light on the molecular mechanism underlying arsenic-induced IR.

Ferroptosis mediated by the interaction between Mfn2 and IREα promotes arsenic-induced nonalcoholic steatohepatitis.

Exposure to arsenic is a risk factor for nonalcoholic steatohepatitis (NASH). Ferroptosis is a form of regulated cell death defined by the accumulation of lipid peroxidation. In the current study, we observed the occurrence of ferroptosis in arsenic-induced NASH by assessing ferroptosis related hallmarks. In vitro, we found that ferrostatin-1 effectively attenuated the executing of ferroptosis and NASH. Simultaneously, the expression of ACSL4 (acyl-CoA synthetase long-chain family member 4) was upregulated in rat's liver and L-02 cells exposed to arsenic. While, suppression of ACSL4 with rosiglitazone or ACSL4 siRNA remarkably alleviated arsenic-induced NASH and ferroptosis through diminishing 5-hydroxyeicosatetraenoic acid (5-HETE) content. Additionally, Mitofusin 2 (Mfn2), a physical tether between endoplasmic reticulum and mitochondria, has rarely been explored in the ferroptosis. Using Mfn2 siRNA or inositol-requiring enzyme 1 alpha (IRE1α) inhibitor, we found NASH and ferroptosis were obviously mitigated through reducing 5-HETE content. Importantly, Co-IP assay indicated that Mfn2 could interact with IRE1α and promoted the production of 5-HETE, ultimately led to ferroptosis and NASH. Collectively, our data showed that ferroptosis is involved in arsenic-induced NASH. These data provide insightful viewpoints into the mechanism of arsenic-induced NASH.

[Curative effect of Wenxin Granule and antiarrhythmic drugs in the treatment of atrial fibrillation:a Meta-analysis].

To evaluate the efficiency and safety between Wenxin Granule and antiarrhythmic drugs in the treatment of atrial fibrillation(AF). A total of 8 major electronic databases(CNKI, WanFang, VIP, CBM, Cochrane Library, Web of Science, PubMed, EMbase) were retrieved since the establishment of the database to January 10, 2019. Two reviewers extracted data, and assessed the methodological quality of the included studies. The Meta-analysis was made by RevMan 5.3 software. Finally, 42 studies involving 4 657 patients were included. The results of Meta-analysis showed that compared with antiarrhythmic drug, the combined administration with Wenxin Granule and antiarrhythmic drug had a better clinical efficiency(OR=3.37, 95%CI[2.69,4.22],I~2=0%,P<0.000 01)and efficacy on cardioversion(OR=2.32,95%CI[1.67,3.22],I~2=0%,P<0.000 01), with reduction in P_d(MD=-5.48,95%CI [-7.32,-3.64],I~2=0%,P<0.000 01)and P_(max)(MD=-9.91,95%CI[-12.86,-6.95],I~2=0%,P<0.000 01). The comparison between the combined application with Wenxin Granule and the single application of amiodarone showed a clinical efficiency(OR=2.89,95%CI[1.96,4.26],I~2=44%,P<0.000 01),and efficacy on sinus rhythm maintenance(OR=2.58,95%CI[1.82,3.66],I~2=3%,P<0.000 01). The comparison between the combined application with Wenxin Granule and the single application of amiodarone showed a clinical efficiency(OR=0.88,95%CI[0.53,1.46],I~2=0%,P=0.63). The combined treatment with Wenxin Granule has a better clinical efficiency in AF better than amiodarone, with no evidence for more benefits from the single administration with Wenxin Granules.

Visible Light-Driven Membraneless Photocatalytic Fuel Cell toward Self-Powered Aptasensing of PCB77.

Artificial photocatalytic systems have been extensively established to mimic the natural solar-energy conversion process for developing useful photoelectric devices. In this work, a membraneless, hydrogen peroxide (H2O2)-based photocatalytic fuel cell (PFC) operated under visible light was proposed and applied in self-powered sensing of 3,3',4,4'-tetrachlorobiphenyl (PCB77). The PFC was comprised of a photoanode fabricated with gold nanoparticles-decorated graphitic C3N4 nanosheet and a cathode modified with hemin-graphene nanocomposites. The combination of both photocatalytic oxidation and electrochemical reduction of H2O2 processes led to electron transfer in the external circuit, which could generate a certain electric power output. Taking the advantage of the inhibited output performance of PFC by PCB77 which interacted with aptamer immobilize on the photoanode, a self-powered aptasensor driven by visible light was achieved, without applying an external electric source. Thus, a highly sensitive and selective self-powered aptasensor for PCB77 was successfully demonstrated.

The efficacy and safety of calcitonin gene-related peptide monoclonal antibody for episodic migraine: a meta-analysis.

OBJECTIVE: This meta-analysis was performed to evaluate the efficacy and safety of monoclonal antibodies against calcitonin gene-related peptide (CGRP) for episodic migraine prevention. METHODS: MEDLINE, EMBASE, Web of Science, and the Cochrane Library were searched from inception to April 2018. Studies considered to be eligible were randomized controlled trials about efficacy and safety of calcitonin gene-related peptide monoclonal antibody for episodic migraine prevention. RESULTS: Eight randomized controlled trials involving 2292 patients were included. The outcomes of this meta-analysis presented that CGRP monoclonal antibodies for preventive treatment of episodic migraine significantly reduced the monthly migraine days from baseline [weighted mean difference (WMD) = - 1.52; 95%CI, - 1.92 to - 1.11; Z = 7.40; P < 0.001] and monthly acute migraine-specific medication consumption from baseline [WMD = - 1.45; 95%CI, - 2.17 to - 0.72; Z = 3.93; P < 0.001], as compared with placebo group. CGRP monoclonal antibodies for preventive treatment of episodic migraine significantly increased the ≥ 50% reduction from baseline in migraine days per month [RR = 1.54; 95%CI, 1.38 to1.71; Z = 7.88; P < 0.001]. The adverse events were similar between the CGRP monoclonal antibody group and placebo group (P = 0.998). The outcomes of subgroup analysis showed that erenumab, galcanezumab, and fremanezumab significantly reduced the monthly migraine days from baseline and increased the ≥ 50% reduction from baseline in migraine days per month. Both erenumab and fremanezumab significantly reduced from baseline. CONCLUSIONS: Based on the results of this meta-analysis, CGRP monoclonal antibodies significantly reduced the monthly migraine days and acute migraine-specific medication. CGRP monoclonal antibodies were effective and safe for preventive treatment of episodic migraine.

Highly Selective Self-Powered Sensing Platform for p-Nitrophenol Detection Constructed with a Photocathode-Based Photocatalytic Fuel Cell.

A photocathode-based photocatalytic fuel cell (PFC) was fabricated and proposed as a self-powered sensor for p-nitrophenol (p-NP) detection. The PFC was comprised of a photocathode and an anode in separated chambers, which could generate suitable power output under photoirradiation to drive the sensing process. In this device, p-type PbS quantum dots-modified glass carbon electrode (GCE) served as the photocathode for the reduction of p-NP under photoirradiation while graphene-modified GCE was employed as the anode for the oxidation of ascorbic acid. In order to improve the selectivity of the PFC sensor, p-NP binding molecularly imprinted polymer (MIP) was introduced on the photocathode. Under optimal conditions, the open circuit voltage of the constructed PFC sensor was found to sensitively respond to p-NP in a wide concentration range from 0.05 µM to 20 µM. The proposed sensor exhibited high selectivity, good reproducibility, and stability, demonstrating the successful combination of MIP with photocathode in construction of high-performance PFC self-powered sensors for pollutant monitoring.

Reversibility-Dependent Photovoltammetric Behavior of Electroactive Compounds on a CdS-Graphene Hybrid Film Electrode.

Photovoltammetric behaviors of irreversible, quasi-reversible and reversible electrochemical systems represented by 2,4-dichlorophenol (DCP), hydroquinone (HQ) and K3 [Fe(CN)6 ], respectively, were investigated on a CdS-graphene hybrid film electrode. The cyclic voltammetric (CV) curves of HQ and K3 [Fe(CN)6 ] showing a pair of redox peaks became sigmoidal in shape under visible light irradiation. In contrast, the CV curve shape of DCP showing an oxidation peak was not changed under photoirradiation, although the oxidation peak current was enhanced by the photoelectrocatalysis. Thus, the reversibility-dependent photovoltammetric behaviors were observed. Furthermore, it was demonstrated that the photovoltammetric curve shapes were not changed by pH and intensity of light source, but were tunable with scan rate and concentration of reactants depending on the reversibility of the electrochemical reactions.

Development of a Novel Energy Saving and Environmentally Friendly Starch via a Graft Copolymerization Strategy for Efficient Warp Sizing and Easy Removal.

Warp sizing is a key process in textile production. However, before the yarn/fabric finishing, such as dyeing, the paste adhering to the warp must be eliminated to ensure optimal dyeing properties and the flexibility of the fabric. Therefore, the sizing will often consume a lot of energy and produce a lot of industrial wastewater, which will cause serious harm to the environment. In this study, we have developed an energy saving and environmentally friendly starch-based slurry by modifying natural starch with acrylamide. The paste has excellent viscosity stability and fiber adhesion, and exhibits excellent performance during warp sizing. In addition, the slurry has good water solubility at 60-70 °C, so it is easy to desize at low temperatures. Because of this, the sizing of the warp can be deslimed directly from the yarn during subsequent washing processes. This work can not only reduce some costs for the textile industry, but also achieve the purpose of energy conservation and emission reduction.

Prospective comparative clinical study: Efficacy evaluation of collagen combined with hyaluronic acid injections for tear trough deformity.

BACKGROUND: Tear trough filling is a popular facial rejuvenation procedure, and hyaluronic acid is typically used as the filler of choice. However, Tyndall's phenomenon, a common complication following hyaluronic acid injection, can occur, leading to skin discoloration of the lower eyelid. AIMS: This single-center, prospective, comparative clinical study aimed to evaluate the efficacy of collagen and hyaluronic acid injections in treating tear trough deformity. METHODS: Sixty patients were enrolled between June 2022 and January 2023. Patients were randomly allocated into three groups: Group A received hyaluronic acid, Group B received hyaluronic acid combined with collagen, and Group C received collagen alone. Baseline characteristics, including age, sex, and tear trough deformity grade were considered before therapy. Changes in tear trough deformity scores, Global Aesthetic Improvement Scores, and the presence of the Tyndall effect were analyzed at 1 and 3 months postinjection to determine differences among the three groups. RESULTS: Baseline profiles of the three groups were similar. In the first month postinjection, there was no difference in the Global Aesthetic Improvement Scores and tear trough deformity between the three groups. However, in the third-month postinjection, there was a significant difference in scores between patients in Group C and those in Groups A or B. The Tyndall effect manifested in three patients in Group A, which was significantly different from that in Groups B and C. CONCLUSION: The combined use of hyaluronic acid with collagen in injectable fillers corrected tear trough deformities and reduced the occurrence of the Tyndall phenomenon, which can be problematic with hyaluronic acid alone. Additionally, this combination may help overcome the disadvantage of a shorter retention period when using collagen alone.

Combined effect of thermal hydrolysis process and low-temperature pyrolysis on the classification and bioavailability of phosphorus in sewage sludge.

Existing phosphorus (P) resources are becoming increasingly scarce, so it is necessary to recover P from potential sources. This paper is based on thermal hydrolysis process (THP) at 140-180 °C, coupled with low-temperature pyrolysis at 300 °C, to study its effect on the recovery and conversion of P from sewage sludge. Most significant change was observed in apatite P, which increased from 3.43 ±â€¯0.48 mg/g in raw sludge to 30.17 ±â€¯1.17 mg/g in biochar (BTHP-180-4-300) during optimal process (THP condition: 180 °C, 4 h; pyrolysis condition: 300 °C). Reactions between phosphates and metal ions became more complete during this combined process. Unstable forms of P were converted into more stable forms, with transformations from Al-P and Fe-P toward Ca-P compounds like Ca3(PO4)2, Ca3Mg3(PO4)4, Ca2P2O7, and Ca(H2PO4)2, making P less degradable and more suitable as slow-release fertilizers. Additionally, P characteristics of actual THP in a sewage treatment plant were similar to those of laboratory THP.

Effect of finerenone on cardiovascular events in kidney disease and/or diabetes: a meta analysis of randomized control trials.

OBJECTIVE: To evaluate the effect of finerenone on cardiovascular events in Kidney Disease and/or Diabetes. METHODS: The ClinicalTrials.gov, Medline, EMBASE, Web of Science, Cochrane Library databases were systematically searched from the inception dates to December 20, 2021 in order to identify randomized controlled trials that evaluated the effect of finerenone on cardiovascular events in Kidney Disease and/or Diabetes, without language restriction. This meta-analysis collected data from 7 randomized clinical trials that evaluated the effect of finrrenone in 15,618 patients with kidney disease and/or diabetes. Risk of bias was assessed by Cochrane Risk of Bias Assessment Tool. Inconsistency among trial results was assessed by I2 statistic. The main endpoints included death from cardiovascular causes, death from any cause, incidence of myocardial infarction, rate of heart failure, hospitalization for any cause, rate of total advent events and study-drug-related adverse events. RESULTS: A total of 7 randomized controlled trials involving 15,618 fulfilled the inclusion criteria. The outcomes of this meta-analysis presented that finerenone significantly reduced the death from any cause (95% CI 0.82-0.99; P = 0.031), risk of heart failure (95% CI 0.67-0.92; P = 0.002) among patients with kidney disease and/or diabetes when compared to control group. Besides, finerenone could not reduce the incidence of death from cardiovascular, myocardial infarction and hospitalization for any cause among patients with kidney disease and/or diabetes (p > 0.05). In terms of safety, finerenone shared the same risk of total advent events with placebo among patients with kidney disease and/or diabetes (p > 0.05). However, finerenone had higher risk of study-drug-related advent events than placebo among patients with kidney disease and/or diabetes (95% CI 1.27-1.48; P < 0.001). CONCLUSIONS: In patients with kidney disease and/or diabetes, treatment with finerenone resulted in lower risk of death from any cause and heart failure than placebo. However, the study-drug-related advent events also increased significantly at the same time.

A ratiometric self-powered aptasensor for simultaneous detection of cortisol and progesterone based on spatially resolved tri-channel photofuel cell.

In this work, a self-powered sensor was proposed for simultaneous detection of two typical steroid hormones, namely cortisol (COR) and progesterone (P4). A tri-channel photofuel cell (PFC) consisting of three spatially resolved SnS2@SnO2 photoanodes and one Pt cathode was designed to generate the electricity to drive the sensing process under the control of a multiplex switch. Among three photoanodes, one served as the control, while the other two were modified with COR-binding or P4-binding aptamer to respond specifically to the COR or P4 target. The ratios of the inhibited PFC output from aptamer-immobilized photoanodes to the reference signal from the control photoanode were utilized for simultaneous detection of COR and P4. The results showed that the developed self-powered sensor exhibited broad concentration ranges toward targets, with COR concentration ranging from 1 nM to 1000 nM and P4 concentration ranging from 1 nM to 500 nM. The detection limits for COR and P4 were calculated to be 0.88 nM and 0.52 nM, respectively. Moreover, the proposed sensing platform demonstrated high selectivity, good reproducibility, and high stability. Finally, the sensor was successfully applied to the simultaneous determination of COR and P4 in a human female serum sample.
