Abstract
BACKGROUND Cilostazol is an antiplatelet drug and is used for stroke prevention and symptomatic peripheral vascular disease. Studies have reported the effects of cilostazol on cognitive function, but the results are inconsistent and have not been systematically assessed. METHODS We systematically searched the PubMed, Embase, and Cochrane databases for relevant clinical studies. The primary outcome was the change in Mini-mental State Examination (MMSE) scores from baseline to the last available follow-up. The secondary outcome was dementia risk. Mean differences and 95% confidence intervals (CIs) were calculated for combining MMSE scores, and the pooled odds ratios and 95% CIs were used to calculate the association between use of cilostazol and dementia risk. RESULTS Overall, 8 eligible studies met inclusion criteria were pooled in meta-analysis. Though with a trend toward favoring cilostazol, the pooled changes in MMSE scores from baseline showed no significant difference in mild cognitive impairment and dementia patients (mean differences 1.02, 95% CI -0.53 to 2.57, P = .195). For secondary outcome, cilostazol reduced the risk of dementia in patients without prior history of dementia (pooled odds ratios 0.90; 95% CI 0.87 to 0.92; P = .000). CONCLUSION These results suggest the potential for cilostazol treatment in the suppression of cognitive decline and prevention of progression to dementia. However, the lack of blinding in most studies is likely to cause an overestimation of the effect sizes, and further well-designed studies are also needed.

Fruquintinib Combined With PD-1 Inhibitors for the Treatment of the Patients With Microsatellite Stability Metastatic Colorectal Cancer: Real-World Data. Clin Oncol (R Coll Radiol) 2024; 38:103700. [PMID: 39700765 DOI: 10.1016/j.clon.2024.103700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 11/12/2024] [Accepted: 11/22/2024] [Indexed: 12/21/2024]
Abstract
AIMS Programmed death-1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibitors have shown limited effectiveness in patients with microsatellite stable (MSS) metastatic colorectal cancer (mCRC). Combining anti-angiogenesis inhibitors with PD-1 inhibitors has the potential to reverse the immunosuppressive tumour microenvironment, synergistically enhancing the anti-tumour immune response in MSS mCRC. The goal is to present real-world data that prove the clinical efficacy and safety of fruquintinib combined with PD-1 inhibitors in MSS mCRC. MATERIALS AND METHODS We conducted a real-world retrospective study in patients with MSS mCRC who received treatment with fruquintinib combined with PD-1 inhibitors between May 2019 and March 2023 in our centre. RESULTS Seventy seven patients with MSS mCRC received fruquintinib combined with PD-1 inhibitors. In total, 5.2% of patients (4/77) achieved a partial response (PR), while 50.6% (39/77) had a stable disease (SD). Notably, three lesions achieving PR were all lung metastases and the overall disease control rate (DCR) reached 55.8% (43/77). Median progression-free survival (PFS) and overall survival (OS) reached 5.1 months (95% CI: 3.6-6.7) and 14.6 months (95% CI: 9.6-15.6), respectively. Multivariate Cox analysis showed that prior treatment without vascular endothelial growth factor (VEGF) inhibitors was significantly associated with PFS and OS (p < 0.05). Further analysis indicated that total- or polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs) significantly decreased after treatment (P = 0.039), especially in the PR/SD group (P = 0.003). Most adverse events included abdominal pain, rash, oedema, diarrhoea, and immunotherapy-associated hypothyroidism, yet symptoms were controllable. CONCLUSION Our results provided additional evidence that patients with MSS mCRC could benefit from the combination of fruquintinib and PD-1 inhibitors, especially those with lung metastases or without prior treatment with VEGF inhibitors. The detection of MDSCs may be an immune indicator for predicting of the combined therapy.

Xi J, Cheng X, Liu J. Causal relationship between gout and liver cancer: A Mendelian randomization and transcriptome analysis. Medicine (Baltimore) 2024; 103:e40299. [PMID: 39533594 PMCID: PMC11557110 DOI: 10.1097/md.0000000000040299] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2024] [Accepted: 10/11/2024] [Indexed: 11/16/2024] Open
Abstract
Gout is an inflammatory arthritis resulting from urate crystal deposition, now recognized as part of metabolic syndrome. Hyperuricemia, a hallmark of gout, is associated with various health complications, including liver cancer. Observational studies indicate a link between gout and increased cancer incidence. However, the causal relationship between gout and hepatocellular carcinoma remains uncertain. This study utilizes Mendelian randomization (MR) to explore this connection, minimizing confounding factors commonly present in observational studies. Genome-wide association study data for gout and liver cancer were sourced from the UK Biobank. We selected single nucleotide polymorphisms that are strongly associated with gout and liver cancer as instrumental variables for the analysis. We conducted 2-sample MR analysis using multiple MR methods (MR-Egger, weighted median, inverse variance weighting, and weighted mode) to evaluate causality. Co-localization and transcriptomic analyses were employed to identify target genes and assess their expression in hepatocellular carcinoma tissues. The 2-sample MR analysis indicated a significant causal relationship between gout and heightened liver cancer risk (P_IVW = .014). Co-localization analysis identified phosphatidylethanolamine N-methyltransferase (PEMT) as a crucial gene associated with gout (pH4 = 0.990). Transcriptomic data showed that PEMT expression was significantly higher in normal liver tissues compared to malignant samples (P < .001), and higher PEMT levels correlated with improved survival outcomes (P = .045). Immunohistochemical analysis revealed lower PEMT expression in hepatocellular carcinoma from patients with concurrent gout compared to those without (P < .05). The results indicate that gout increases the risk of hepatocellular carcinoma, with PEMT potentially playing a key role. Although this study focused on European populations, indicating a need for further research in diverse groups, the results emphasize the potential for liver cancer screening in newly diagnosed gout patients. Understanding the relationship between these conditions may inform future clinical practices and cancer prevention strategies.

JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2024; 104:8975-8990. [PMID: 38989589 DOI: 10.1002/jsfa.13725] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 06/02/2024] [Accepted: 06/13/2024] [Indexed: 07/12/2024]
Abstract
BACKGROUND To extract anthocyanins with high efficiency, a hypothesis for high-speed shear homogenization extraction (HSHE) method was established through a combination of solvent and ultrasonic-assisted extractions. The efficacy of this hypothesis was demonstrated by performing qualitative and quantitative analyses of 16 anthocyanins extracted from five northern vegetables, and five berry fruits using ultra-high-performance Q-Exactive Orbitrap tandem mass spectrometry. Single-factor experiments were conducted by varying ethanol concentration, temperature, pH and extraction cycles to determine the optimal conditions for this method. RESULTS Optimal extraction conditions (ethanol 70-80%, 40-50 °C, pH 3-4, performed twice) were determined using an HSHE (5 min, 10 000 rpm, 25 °C) assisted shaker (60 min) and ultrasonication (40 kHz, 160 W cm-2, 30 min, 25 °C) procedure. Compared to the traditional non-HSHE method, the total anthocyanin content obtained through HSHE extraction showed a significant increase, ranging from 1.0 to 3.9 times higher, with purple cabbage exhibiting the most pronounced enhancement in content. More types of anthocyanins were detected in blueberry (9), black bean (7) and raspberry (5), of which malvidin was the major anthocyanin (0.426 g kg-1) in blueberry, having an amount five times than previously obtained. CONCLUSION The established HSHE method has been proven to be a superior technique for anthocyanin extraction, with higher extraction efficiency and concentrations. This technique also provides a new avenue for extracting bioactive compounds from diverse food sources, with potential applications in improving the functional properties of food products. © 2024 Society of Chemical Industry.

Abstract
Improving the conductivity of the electrocatalyst itself is essential for enhancing its performance. In this work, N, S-rich 6-thioguanine (TG) is selected as the ligand to synthesize a Fe, Ni bimetallic porous coordination polymer (PCP), which is then derived to fabricate N,S codoped carbon (NSC)-coated (Fe,Ni)9S8/Ni3S2 bridged nanowires. The (Fe,Ni)9S8/Ni3S2@NSC bridged nanowires obtained through bimetallic synergistic catalysis and self-sulfurization processes not only introduced additional electrocatalytic active sites but also significantly enhance the overall conductivity of the catalyst due to the interconnected nanowire structure. The resulting (Fe,Ni)9S8/Ni3S2@NSC demonstrates remarkable oxygen evolution reaction (OER) performance, exhibiting an overpotential as low as 252 mV at a current density of 10 mA cm-2. This work proposes a novel strategy for enhancing the overall conductivity of catalysts by growing bridged nanowires, providing valuable insights and inspiration for the design and preparation of advanced transition metal sulfide electrocatalysts.

Abstract
Aging, a process of functional decline with the increase of chronological age, is a major risk factor for chronic diseases. Aging shows significant individual differences, which is influenced by both genetic and environmental factors. Accurate measurement of physiological age helps identify individuals with accelerated aging and those at high risk for chronic diseases and mortality, which would promote individual health management and precision medicine for healthy aging. In this paper, we summarize the omics-based aging clocks and discuss their current and future applications.

Abstract
OBJECTIVE To explore the impact of CACNA1C rs58619945 genotype on the cortical thickness of attentional networks in patients with Bipolar 1 disorder type (BD-Ⅰ). METHODS From August 2013 and August 2019, a total of 155 BD-Ⅰ patients were recruited from the outpatient and inpatient Departments of the Affiliated Brain Hospital of Guangzhou Medical University, along with 82 healthy controls (HC) from the community and university. Genotype for the CACNA1C rs58619945 locus was determined for all BD-I patients and HC subjects, followed by 3.0 T magnetic resonance imaging scans to measure the cortical thickness in the alert, orienting, and executive control subnetworks. General linear models (GLMs) were used to evaluate the impact of CACNA1C rs58619945 on the cortical thickness of attentional networks. Concurrently, attentional dimension functions were assessed using repeatable battery for the assessment of neuropsychological status (RBANS) and Cambridge neuropsychological test automated battery rapid visual information processing (CANTAB RVP) test. RESULTS Compared with the HC group, the BD-I patients had shown reduced thickness in bilateral prefrontal cortex, bilateral posterior cingulate cortex, and bilateral superior temporal cortex. A significant interaction between the CACNA1C genotype and the cortical thickness of right prefrontal cortex, right posterior parietal cortex and right superior temporal cortex was noted. Partial correlation analysis has demonstrated a significant correlation between CANTAB RVP and RBANS attention indices and cortical thickness in the right prefrontal cortex, right posterior cingulate cortex, and right superior temporal cortex predominantly among carriers of the BD-I G allele. CONCLUSION The G allele of CACNA1C rs58619945 is associated with cortical thickness of the right prefrontal cortex, right posterior cingulate cortex, and right superior temporal cortex in BD-Ⅰ, which are part of the alerting and orienting network.

Abstract
BACKGROUND Wilson's disease (WD) is a rare autosomal recessive disease that causes impaired copper circulation and excretion. The initial manifestations of WD vary clinically, which makes early diagnosis very difficult. Sleep disorders have been described as common symptoms of WD, but the initial manifestations are in rare cases. CASE REPORT This study aims to present a patient with acute insomnia as the initial manifestation of WD. Cranial magnetic resonance imaging showed extensive lesions in the bilateral putamen and caudate nucleus, pressure area of corpus callosum, midbrain, and pons. Interestingly, rare but characteristic signs of WD, such as "face of the giant panda," were shown in this case. WD diagnosis was further established by decreased ceruloplasmin level and ATP7B (adenosine-triphosphatase copper transporting beta polypeptide) gene mutations. CONCLUSIONS We describe acute insomnia as the initial manifestation of WD in a 21-year-old male patient. Timely diagnosis allows for early copper-eliminating pharmacotherapy, which is of high prognostic importance, as the patient may be more responsive to treatment at this point.

Abstract
Precipitation was an important obstacle to improving zinc's bioavailability. Therefore, zinc-whey protein hydrolysate-chitosan oligosaccharide (Zn-WPH-COS) complexes (167 nm) were prepared by linking Zn-WPH (zinc: 18.4%) with COS (1:1, 2 h) to enhance zinc's bioaccessibility. Fourier-transform infrared showed Zn-WPH formed with zinc replaced hydrogen (from 3274 to 3279 cm-1) and reacted with COO- (C-N: from 1394 to 1402 cm-1), a new peak at 1025 cm-1 proved COS can be successful cross-linked (Zn-WPH-COS). Fluorescence spectra showed zinc and COS reduced WPH hydrophobicity (28.0 and 39.0%, respectively). Circular dichroism showed zinc decreased WPH α-helix (from 13.7 to 11.5%), in contrast with COS to Zn-WPH. Zinc solubility and dialyzability were increased (64.5/ 54.2% vs 50.2/ 41.2% vs 29.5/ 21.7%) in Zn-WPH-COS, compared with Zn-WPH and ZnSO4·7H2O, respectively, due to the smallest size (167 nm) and COS protection on Zn-WPH (gastric digestion). These results indicate Zn-WPH-COS could significantly improve the digestion and absorption of zinc.

Abstract
HnRNPK, a prominent member of the heterogeneous nuclear ribonucleoprotein (hnRNP) family, is widely expressed in mammalian tissues and plays a crucial role in animal development. Despite its well-established functions, limited information is available regarding its role in skeletal muscle development and regeneration. To elucidate the functional role of hnRNPK in skeletal muscle, we utilized Pax7CreER; HnrnpkLoxP/LoxP (Hnrnpk pKO) mice as a model, isolated primary mouse skeletal muscle satellite cells (MuSCs), and induced hnRNPK knockout using 4-OTH. Transcriptome sequencing was performed on four distinct groups: Hnrnpk pKO MuSCs undergoing proliferation for 24 h (ethanol 24 h) and 48 h (ethanol 48 h) after treatment with ethanol as the control, as well as Hnrnpk pKO MuSCs undergoing proliferation for 24 h (4-OHT 24 h) and 48 h (4-OHT 48 h) after treatment with 4-OHT as the hnRNPK-induced knockout group. The RNA sequencing data was generated using the Illumina HiSeq 2000/2500 sequencing platform. The raw data files have been archived in the Sequence Read Archive at the China National Center for Bioinformation (CNCB) under the accession number CRA015864. This data article is related to the research paper "Deletion of heterogeneous nuclear ribonucleoprotein K in satellite cells leads to inhibited skeletal muscle regeneration in mice, Genes & Diseases 11: 101,062, DOI: 10.1016/j.gendis.2023.06.031".

Abstract
Accurate haplotyping facilitates distinguishing allele-specific expression, identifying cis-regulatory elements, and characterizing genomic variations, which enables more precise investigations into the relationship between genotype and phenotype. Recent advances in third-generation single-molecule long read and synthetic co-barcoded read sequencing techniques have harnessed long-range information to simplify the assembly graph and improve assembly genomic sequence. However, it remains methodologically challenging to reconstruct the complete haplotypes due to high sequencing error rates of long reads and limited capturing efficiency of co-barcoded reads. We here present a pipeline, AsmMix, for generating both contiguous and accurate diploid genomes. It first assembles co-barcoded reads to generate accurate haplotype-resolved assemblies that may contain many gaps, while the long-read assembly is contiguous but susceptible to errors. Then two assembly sets are integrated into haplotype-resolved assemblies with reduced misassembles. Through extensive evaluation on multiple synthetic datasets, AsmMix consistently demonstrates high precision and recall rates for haplotyping across diverse sequencing platforms, coverage depths, read lengths, and read accuracies, significantly outperforming other existing tools in the field. Furthermore, we validate the effectiveness of our pipeline using a human whole genome dataset (HG002), and produce highly contiguous, accurate, and haplotype-resolved assemblies. These assemblies are evaluated using the GIAB benchmarks, confirming the accuracy of variant calling. Our results demonstrate that AsmMix offers a straightforward yet highly efficient approach that effectively leverages both long reads and co-barcoded reads for haplotype-resolved assembly.

Abstract
KEY MESSAGE Xinong 511, a new wheat-Thinopyrum ponticum variety with excellent fusarium head blight resistance, the QTLs were mapped to the wheat chromosomes 5B and 7A with named QFhb.nwafu-5B and QFhb.nwafu-7A, respectively. Novel Fusarium head blight (FHB) resistance germplasms and genes are valuable for wheat improvement and breeding efforts. Thinopyrum ponticum, a wild relative of common wheat, is a valuable germplasm of disease resistance for wheat improvement and breeding. Xinong 511 (XN511) is a high-quality wheat variety widely cultivated in the Yellow and Huai Rivers Valley of China with stable FHB-resistance. Through analysis of pedigree materials of the wheat cultivar XN511, we found that the genetic material and FHB resistance from Th. ponticum were transmitted to the introgression line, indicating that the FHB resistance in XN511 likely originates from Th. ponticum. To further explore the genetic basis of FHB resistance in XN511, QTL mapping was conducted using the RILs population of XN511 and the susceptible line Aikang 58 (AK58). Survey with makers closely-linked to Fhb1, Fhb2, Fhb4, Fhb5, and Fhb7, indicated that both XN511 and the susceptible lines do not contain these QTL. Using bulked segregant analysis RNA-seq (BSR-Seq) and newly developed allele-specific PCR (AS-PCR) markers, QTLs in XN511 were successfully located on wheat chromosomes 5B and 7A. These findings are significant for further understanding and utilizing FHB resistance genes in wheat improvement.

Abstract
BACKGROUND Bipolar disorder (BD) is a progressive condition. Investigating the neuroimaging mechanisms in depressed adolescents with subthreshold mania (SubMD) facilitates the early identification of BD. However, the global brain connectivity (GBC) patterns in SubMD patients, as well as the relationship with processing speed before the onset of full-blown BD, remain unclear. METHODS The study involved 72 SubMD, 77 depressed adolescents without subthreshold mania (nSubMD), and 69 gender- and age-matched healthy adolescents (HCs). All patients underwent a clinical follow-up ranging from six to twelve months. We calculated the voxel-based graph theory analysis of the GBC map and conducted the TMT-A test to measure the processing speed. RESULTS Compared to HCs and nSubMD, SubMD patients displayed distinctive GBC index patterns: GBC index decreased in the right Medial Superior Frontal Gyrus (SFGmed.R)/Superior Frontal Gyrus (SFG) while increased in the right Precuneus and left Postcentral Gyrus. Both patient groups showed increased GBC index in the right Inferior Temporal Gyrus. An increased GBC value in the right Supplementary Motor Area was exclusively observed in the nSubMD-group. There were opposite changes in the GBC index in SFGmed.R/SFG between two patient groups, with an AUC of 0.727. Additionally, GBC values in SFGmed.R/SFG exhibited a positive correlation with TMT-A scores in SubMD-group. LIMITATIONS Relatively shorter follow-up duration, medications confounding, and modest sample size. CONCLUSION These findings suggest that adolescents with subthreshold BD have specific impairments patterns at the whole brain connectivity level associated with processing speed impairments, providing insights into early identification and intervention strategies for BD.

Abstract
Objective: To explore the efficacy of arthroscopic release in treating postoperative knee adhesion and investigate the influence of release timing on the treatment outcomes. Methods: A total of 50 patients who accepted arthroscopic release in Peking University Third Hospital from February 2017 to December 2021 were included in the retrospective cohort. The study cohort comprised 28 men and 22 women, with a mean age of (30.8±11.9) years. All the primary surgeries were manipulated under arthroscopes. A comparison was made between pre-and postoperative range of motion (ROM), visual analog scale (VAS), International Knee Documentation Committee (IKDC) scores, and Tegner activity scale scores for the patients. According to the interval between the appearance of adhesion and arthroscopic release, the patients were divided into four groups:<3 months group (n=12), 3-6 months group (n=16),>6-12 months group (n=14), and>12 months group (n=8). Inter-group comparisons on postoperative ROM, IKDC scores, and Tegner activity scale scores and improvement values of each outcome were conducted. Results: All the patients were followed up for (36.4±19.7) months. Patients gained significant improvement in flexion, extension, IKDC scores, and Tegner scores (125.0°±20.0° vs 75.7°±27.5°, 2.3°±4.8° vs 7.4°±7.3°, 69.8±17.7 vs 51.4±12.8, 4.1±2.1 vs 2.2±1.1) (all P<0.05), while the VAS scores did not show significant improvement. There were no significant differences among different groups in postoperative extension, IKDC scores or Tegner scores, nor in their improvements. However, patients in the ≤6 months group could gain better postoperative flexion and improvement in flexion than those in the >6 months group (129.9°±20.0° vs 118.8°±17.4°, 58.6°±32.8° vs 37.3°±23.1°) (P<0.05). Conclusions: Arthroscopic release presents a great effect in treating knee adhesion after arthroscopic operation. Once the symptoms of adhesion appear and physical rehabilitation fails to improve the ROM, one should accept early surgical intervention (less than 6 months) for a better outcome.

Abstract
Tanoak (Notholithocarpus densiflorus) is an evergreen tree in the Fagaceae family found in California and southern Oregon. Historically, tanoak acorns were an important food source for Native American tribes, and the bark was used extensively in the leather tanning process. Long considered a disjunct relictual element of the Asian stone oaks (Lithocarpus spp.), phylogenetic analysis has determined that the tanoak is an example of convergent evolution. Tanoaks are deeply divergent from oaks (Quercus) of the Pacific Northwest and comprise a new genus with a single species. These trees are highly susceptible to "sudden oak death" (SOD), a plant pathogen (Phytophthora ramorum) that has caused widespread deaths of tanoaks. In this study, we set out to assemble the genome and perform comparative studies among a number of individuals that demonstrated varying levels of susceptibility to SOD. First, we sequenced and de novo assembled a draft reference genome of N. densiflorus using cobarcoded library processing methods and an MGI DNBSEQ-G400 sequencer. To increase the contiguity of the final assembly, we also sequenced Oxford Nanopore long reads to 30× coverage. To our knowledge, the draft genome reported here is one of the more contiguous and complete genomes of a tree species published to date, with a contig N50 of ∼1.2 Mb, a scaffold N50 of ∼2.1 Mb, and a complete gene score of 95.5% through BUSCO analysis. In addition, we sequenced 11 genetically distinct individuals and mapped these onto the draft reference genome, enabling the discovery of almost 25 million single nucleotide polymorphisms and ∼4.4 million small insertions and deletions. Finally, using cobarcoded data, we were able to generate a complete haplotype coverage of all 11 genomes.

Abstract
The synergistic effects of phosphorylated zein nanoparticles (PZNP) and cellulose nanocrystals (CNC) in enhancing the wetting and barrier properties of chitosan hydrochloride (CHC)-based coating are investigated characterized by Fourier Transform Infrared Spectra (FTIR), X-ray Diffraction (XRD), atomic force microscopy and by investigating the mechanical properties, etc., with the aim of reducing cherry rain cracking. FTIR and XRD showed dual nanoparticles successfully implanted into CHC, CHC-PZNP-CNC combined moderate ductility (elongation at break: 7.8 %), maximum tensile strength (37.5 MPa). The addition of PZNP alone significantly improved wetting performance (Surface Tension, CHC: 55.3 vs. CHC-PZNP: 48.9 mN/m), while the addition of CNC alone led to a notable improvement in the water barrier properties of CHC (water vapor permeability, CHC: 6.75 × 10-10 vs. CHC-CNC: 5.76 × 10-10 gm-1 Pa-1 s-1). The final CHC-PZNP-CNC coating exhibited enhanced wettability (51.2 mN/m) and the strongest water-barrier property (5.32 × 10-10 gm-1 Pa-1 s-1), coupled with heightened surface hydrophobicity (water contact angle: 106.4°). Field testing demonstrated the efficacy of the CHC-PZNP-CNC coating in reducing cherry rain-cracking (Cracking Index, Control, 42.3 % vs. CHC-PZNP-CNC, 19.7 %; Cracking Ratio, Control, 34.6 % vs. CHC-PZNP-CNC, 15.8 %). The CHC-PZNP-CNC coating is a reliable option for preventing rain-induced cherry cracking.

Abstract
BACKGROUND Cerebral small vessel disease (CSVD) is prevalent in the population, especially among the elderly. Various types of CSVD markers commonly coexist, and the neurological function outcome is affected by their combined effect. Studies investigating the association between total CSVD burden and stroke outcomes in large vessel occlusion (LVO) stroke receiving endovascular treatment (EVT) are expanding but have not been systematically assessed. METHODS We systematically searched the PubMed, Embase, and Cochrane databases for relevant clinical studies. The total CSVD burden score summarized the markers of CSVD, including lacunes, white matter hyperintensities (WMHs), cerebral microbleeds (CMBs), and enlarged perivascular spaces (EPVSs), which was a comprehensive index of overall CSVD burden. The pooled odds ratios (ORs) were used to calculate the association between high total CSVD burden score and outcomes of EVT in patients with LVO stroke. The primary outcome was poor functional outcome, which was defined as a modified Rankin Scale score (mRS) ≥ 3 at 90 days after EVT. The secondary outcomes were symptomatic intracranial hemorrhage (sICH) and poor collateral flow. RESULTS Overall, 6 eligible studies with 1,774 patients with LVO stroke undergoing EVT were pooled in meta-analysis. High overall CSVD burden score was significantly associated with increased risks of poor functional outcome at 90 days (pooled OR 2.86, 95 % CI 1.31-6.25, p = 0.008). Besides, high overall CSVD burden score was associated with sICH (pooled OR 2.07, 95 % CI 0.38-5.17; p = 0.118) and poor collateral flow (pooled OR 1.57, 95 % CI 0.75-3.27; p = 0.232), but were not statistically significant. CONCLUSIONS High overall CSVD burden was associated with increased risks of unfavorable outcomes in patients with LVO stroke undergoing EVT.

Abstract
Converging evidence has revealed disturbances in the corticostriatolimic system are associated with suicidal behaviors in adults with major depressive disorder. However, the neurobiological mechanism that confers suicidal vulnerability in depressed adolescents is largely unknown. A total of 86 depressed adolescents with and without prior suicide attempts (SA) and 47 healthy controls underwent resting-state functional imaging (R-fMRI) scans. The dynamic amplitude of low-frequency fluctuations (dALFF) was measured using sliding window approach. We identified SA-related alterations in dALFF variability primarily in the left middle temporal gyrus, inferior frontal gyrus, middle frontal gyrus (MFG), superior frontal gyrus (SFG), right SFG, supplementary motor area (SMA) and insula in depressed adolescents. Notably, dALFF variability in the left MFG and SMA was higher in depressed adolescents with recurrent suicide attempts than in those with a single suicide attempt. Moreover, dALFF variability was capable of generating better diagnostic and prediction models for suicidality than static ALFF. Our findings suggest that alterations in brain dynamics in regions involved in emotional processing, decision-making and response inhibition are associated with an increased risk of suicidal behaviors in depressed adolescents. Furthermore, dALFF variability could serve as a sensitive biomarker for revealing the neurobiological mechanisms underlying suicidal vulnerability.

Abstract
AIM To determine whether net water uptake (NWU) based on automated software evaluation could predict futile recanalisation in patients with acute anterior circulation large-vessel occlusion (LVO). MATERIALS AND METHODS Patients with acute anterior circulation LVO undergoing mechanical thrombectomy in Jinling Hospital were evaluated retrospectively. NWU and other baseline data were evaluated by performing univariate and multivariate analyses. The primary endpoint was 90-day modified Rankin scale score ≥3. A nomogram to predict poor clinical outcomes was developed based on multivariate logistic regression analysis. RESULTS Overall, 135 patients who underwent thrombectomy with a TICI grade ≥2b were enrolled. In multivariate logistic regression analysis, the following factors were identified as independent predictors of futile recanalisation: age (odds ratio [OR]: 1.055, 95 % confidence interval [CI]: 1.004-1.110, p=0.035), female (OR: 0.289, 95 % CI: 0.098-0.850, p=0.024), hypertension (OR: 3.182, 95 % CI: 1.160-8.728, p=0.025), high blood glucose level (OR: 1.36, 95 % CI: 1.087-1.701, p=0.007), admission National Institutes of Health Stroke Scale score (OR: 1.082, 95 % CI: 1.003-1.168, p=0.043), and NWU (OR: 1.312, 95 % CI: 1.038-1.659, p=0.023). CONCLUSIONS NWU based on Alberta Stroke Program Early Computed Tomography (CT) Score (ASPECTS) could be used to predict the occurrence of futile recanalisation in patients with acute anterior circulation LVO ischaemic stroke.

Abstract
KEY MESSAGE A total of 90,000 capture probes derived from wheat and Thinopyrum elongatum were integrated into one chip, which served as an economical genotype for explorating Thinopyrumspecies and their derivatives. Thinopyrum species play a crucial role as a source of new genetic variations for enhancing wheat traits, including resistance to both abiotic and biotic factors. Accurate identification of exogenous chromosome(s) or chromosome segments or genes is essential following the introduction of alien genetic material into wheat, but this task remains challenging. This study aimed to develop a high-resolution wheat-Thinopyrum elongatum array, named GenoBaits®WheatplusEE, to trace alien genetic information by genotyping using a target sequencing system. This GenoBaits®WheatplusEE array included 90,000 capture probes derived from two species and integrated into one chip, with 10,000 and 80,000 originating from wheat and Th. elongatum, respectively. The capture probes were strategically positioned in genes and evenly distributed across the genome, facilitating the development of a roadmap for identifying each alien gene. The array was applied to the high-throughput identification of the alien chromosomes or segments in Thinopyrum and distantly related species and their derivatives. Our results demonstrated that the GenoBaits®WheatplusEE array could be used for direct identification of the breakpoint of alien segments, determine copy number of alien chromosomes, and reveal variations in wheat chromosomes by a single round of target sequencing of the sample. Additionally, we could efficiently and cost-effectively genotype, supporting the exploration of subgenome composition, phylogenetic relationships, and polymorphisms in essential genes (e.g., Fhb7 gene) among Thinopyrum species and their derivatives. We hope that GenoBaits®WheatplusEE will become a widely adopted tool for exporting wild germplasm for wheat improvement in the future.

Abstract
The hypocretin (Hcrt) (also known as orexin) neuropeptidic wakefulness-promoting system is implicated in the regulation of spatial memory, but its specific role and mechanisms remain poorly understood. In this study, we revealed the innervation of the medial entorhinal cortex (MEC) by Hcrt neurons in mice. Using the genetically encoded G-protein-coupled receptor activation-based Hcrt sensor, we observed a significant increase in Hcrt levels in the MEC during novel object-place exploration. We identified the function of Hcrt at presynaptic glutamatergic terminals, where it recruits fast-spiking parvalbumin-positive neurons and promotes gamma oscillations. Bidirectional manipulations of Hcrt neurons' projections from the lateral hypothalamus (LHHcrt) to MEC revealed the essential role of this pathway in regulating object-place memory encoding, but not recall, through the modulation of gamma oscillations. Our findings highlight the significance of the LHHcrt-MEC circuitry in supporting spatial memory and reveal a unique neural basis for the hypothalamic regulation of spatial memory.
