Ovarian-adnexal reporting and data system ultrasound evaluation and pathological characteristics of ovarian collision tumor

BACKGROUND Collision tumor are neoplasms,including two histologically distinct tumors that coexist in the same mass without histological admixture.The incidence of collision tumor is low and is rare clinically.AIM To investigate ultrasound images and application of ovarian-adnexal reporting and data system(O-RADS)to evaluate the risk and pathological characteristics of ovarian collision tumor.METHODS This study retrospectively analyzed 17 cases of ovarian collision tumor diagnosed pathologically from January 2020 to December 2023.All clinical features,ultrasound images and histopathological features were collected and analyzed.The O-RADS score was used for classification.The O-RADS score was determined by two senior doctors in the gynecological ultrasound group.Lesions with O-RADS score of 1-3 were classified as benign tumors,and lesions with O-RADS score of 4 or 5 were classified as malignant tumors.RESULTS There were 17 collision tumors detected in 16 of 6274 patients who underwent gynecological surgery.The average age of 17 women with ovarian collision tumor was 36.7 years(range 20-68 years),in whom,one occurred bilaterally and the rest occurred unilaterally.The average tumor diameter was 10 cm,of which three were 2-5 cm,11 were 5-10 cm,and three were>10 cm.Five(29.4%)tumors with O-RADS score 3 were endometriotic cysts with fibroma/serous cystadenoma,and unilocular or multilocular cysts contained a small number of parenchymal components.Eleven(64.7%)tumors had an O-RADS score of 4,including two in category 4A,six in category 4B,and three in category 4C;all of which were multilocular cystic tumors with solid components or multiple papillary components.One(5.9%)tumor had an O-RADS score of 5.This case was a solid mass,and a small amount of pelvic effusion was detected under ultrasound.The pathology was high-grade serous cystic cancer combined with cystic mature teratoma.There were nine(52.9%)tumors with elevated serum carbohydrate antigen(CA)125 and two(11.8%)with elevated serum CA19-9.Histological and pathological results showed that epithelial-cell-derived tumors combined with other tumors were the most common,which was different from previous results.CONCLUSION The ultrasound images of ovarian collision tumor have certain specificity,but diagnosis by preoperative ultrasound is difficult.The combination of epithelial and mesenchymal cell tumors is one of the most common types of ovarian collision tumor.The O-RADS score of ovarian collision tumor is mostly≥4,which can sensitively detect malignant tumors.

Identification of Serum Exosomal MicroRNA Expression Profiling in Menopausal Females with Osteoporosis by High-throughput Sequencing

Estrogen deficiency,which mainly occurs in postmenopausal women,is a primary reason for osteoporosis in clinical diagnosis.However,the molecular regulation of osteoporosis in menopausal females is still not adequately explained in the literature,with the diagnosis and treatment for osteoporosis being limited.Herein,exosomal microRNAs(miRNAs)were used to evaluate their diagnosis and prediction effects in menopausal females with osteoporosis.In this study,6 menopausal females without osteoporosis and 12 menopausal females with osteoporosis were enrolled.The serum exosomes were isolated,and the miRNA expression was detected by miRNA high-throughput sequencing.Exosomal miRNA effects were analyzed by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses.The miRNA-targeted genes were evaluated by Targetscan 7.2 and the protein-protein interactions(PPI)by STRING.Hub genes were analyzed by the CytoHubba app of Cytoscape.The results showed that 191 aberrant miRNAs were found in the group of menopausal females with osteoporosis,including 72 upregulated miRNAs and 121 downregulated miRNAs.Aberrant miRNAs were involved in many signaling pathways,such as the Wnt,MAPK,and Hippo pathways.Based on PPI network analysis,FBXL3,FBXL13,COPS2,UBE2D3,DCUN1D1,DCUN1D4,CUL3,FBXO22,ASB6,and COMMD2 were the 10 most notable genes in the PPI network.In conclusion,aberrant serum exosomal miRNAs were associated with an altered risk of osteoporosis in menopausal females and may act as potential biomarkers for the prediction of risk of osteoporosis in menopausal females.

Comparison of the oncological,perioperative and functional outcomes of partial nephrectomy versus radical nephrectomy for clinical T1b renal cell carcinoma:A systematic review and metaanalysis of retrospective studies

Objective:To conduct a meta-analysis assessing the perioperative,functional and oncological outcomes of partial nephrectomy(PN)and radical nephrectomy(RN)for T1b tumours.The primary endpoints were the oncological outcomes.The secondary endpoints were the perioperative and functional outcomes.Methods:A systematic literature review was performed by searching multiple databases through February 2019 to identify eligible comparative studies according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement.Identified reports were assessed according to the Newcastle-Ottawa Scale for nonrandomized controlled trials.Results:Overall,13 retrospective cohort studies were included in the analysis.Patients undergoing PN were younger(weighted mean difference[WMD]3.49 years,95%confidence interval[CI]5.16 to1.82;p<0.0001)and had smaller masses(WMD0.45 cm,95%CI0.59 to0.31;p<0.0001).There were no differences in the oncological outcome,which was demonstrated by progression-free survival(hazard ratio[HR]0.70;pZ0.22),cancerspecific mortality(HR 0.91;pZ0.57)and all-cause mortality(HR 1.01;pZ0.96).The two procedures were similar in estimated blood loss(WMD16.47 mL;pZ0.53)and postoperative complications(risk ratio[RR]1.32;pZ0.10),and PN provided better renal function preservation and was related to a lower likelihood of chronic kidney disease onset(RR 0.38;pZ0.006).Conclusion:PN is an effective treatment for T1b tumours because it offers similar surgical morbidity,equivalent cancer control,and better renal preservation compared to RN.

In vitro study on blocking mTOR signaling pathway in EGFR-TKI resistance NSCLC

Objective:To investigate the effect and mechanism of inhibitor everolimus on EGFR-TKI resistance NSCLC.Methods:MTT assay was used to detect proliferation of human non-small cell lung cancer cell line A549.Flow cytometry was used to detect the changes of apoptosis and cycle distribution in each group after 24 h and 48 h.RT-PCR was used to detect the changes of PTEN and 4EBP1 expression levels after 48 h of monotherapy and combination therapy.Results:MTT assay showed that everolimus had dose-dependent inhibition against growth of A549 cells.Flow cytometry showed when everolimus could induce apoptosis and induce G0/G1 phase cell cycle arrest,which was time-dependent(P<0.05).RT-PCR showed everolimus could increase PTEN and 4EBP1 expression.Conclusions:mTOR inhibitor everolimus has an inhibitory effect on EGFR-TKI resistant NSCLC,which cannot reverse the resistance effect of EGFR-TKI resistant cell line A549.The relationship between EGFR/AKT signaling pathway and the mTOR signaling pathway and the mechanism in non-small cell lung cancer need further study.

Effects of plant density and mepiquat chloride application on cotton boll setting in wheat–cotton double cropping system

Sowing cotton directly after harvesting wheat in the Yangtze River Valley of China requires early mature of cotton without yield reduction.Boll-setting period synchronisation and more yield bolls distributed at the upper and middle canopy layers are also required for harvesting.The objective of this study is to quantify the individual and interaction effects of plant density and plant growth regulator mepiquat chloride(MC)on temporal and spatial distributions of yield bolls,as well as yield and yield components.During the 2013–2016 cotton growing seasons,the experiments were conducted on a shortseason cotton cultivar CRRI50 at Yangzhou University,China.Various combinations of plant density(12.0,13.5 and 15.0 plants m^(–2))and MC dose(180,270 and 360 g ha^(–1))were applied on cotton plants.The combination of 13.5 plants m^(–2)and 270 g ha^(–1)MC resulted in the greatest boll number per unit area,the highest daily boll setting number and more than 90%of bolls positioned within 45–80 cm above the ground.In conclusion,appropriate MC dose in combination of high plant density could synchronize boll-setting period and retain more bolls at the upper and middle canopy layers without yield reduction in the system of direct-seeded cotton after wheat harvest,and thus overcome the labor-intensive problem in current transplanting cropping system.

As the main inorganic component of human bones and teeth,hydroxyapatite(HAP)materials have been widely investigated for various applications especially in the biomedical field.Recently,HAP nanowires(HAP NWs)have attracted research interest in the energy and environment-related fields owing to their advantages such as excellent biocompatibility and bioactivity,high-thermal stability,surface modification and functionalization,and selfassembly to form nanoscale porous networked structure.In this review,we first briefly discuss the synthesis of HAP NWs.Then we focus on summarizing the foremost advances in energy and environment-related applications of HAP NWs,including the battery,solar energy-assisted water evaporation,light-driven self-propelled device,thermal insulation,fireresistant inorganic paper,water purification,air purification,molecular detection,superhydrophobic surface,and high-strength nanocomposite materials.In addition,the future research directions on HAP NWs and their energy and environmental applications are proposed.This review aims to provide inspiration and stimulate extensive future studies in the energy and environmental applications of HAP NWs and other inorganic NWs.

Differential expression of glial cell line-derived neurotrophic factor splice variants in the mouse brain

Glial cell line-derived neurotrophic factor(GDNF) plays a critical role in neuronal survival and function. GDNF has two major splice variants in the brain,α-pro-GDNF and β-pro-GDNF, and both isoforms have strong neuroprotective effects on dopamine neurons. However, the expression of the GDNF splice variants in dopaminergic neurons in the brain remains unclear. Therefore, in this study, we investigated the mRNA and protein expression of α-and β-pro-GDNF in the mouse brain by real-time quantitative polymerase chain reaction, using splice variant-specific primers, and western blot analysis. At the mRNA level,β-pro-GDNF expression was significantly greater than that of α-pro-GDNF in the mouse brain. In contrast, at the protein level,α-pro-GDNF expression was markedly greater than that of β-pro-GDNF. To clarify the mechanism underlying this inverse relationship in mRNA and protein expression levels of the GDNF splice variants, we analyzed the expression of sorting protein-related receptor with A-type repeats(SorLA) by real-time quantitative polymerase chain reaction. At the mRNA level, SorLA was positively associated with β-pro-GDNF expression, but not with α-pro-GDNF expression. This suggests that the differential expression of α-and β-pro-GDNF in the mouse brain is related to SorLA expression. As a sorting protein, SorLA could contribute to the inverse relationship among the mRNA and protein levels of the GDNF isoforms. This study was approved by the Animal Ethics Committee of Xuzhou Medical University, China on July 14, 2016.

Strength-ductility balance of AZ31 magnesium alloy via accumulated extrusion bonding combined with two-stage artificial cooling Author links open overlay panel

AZ31 Mg alloy with heterogeneous bimodal grain structure(smaller grain size of 5-20µm and coarser grain size of 100-200µm)was subjected to accumulated extrusion bonding(AEB)at 250℃combined with two-stage artificial cooling in this work,viz.local water cooling and artificial cooling.The microstructure developed consecutively as a result of discontinuous dynamic recrystallization(DDRX)for the AEBed samples.{10-12}tensile twinning also played an important role for the AEB with local water cooling at the initial extrusion stage in the container.Local water cooling could further reduce the DRXed grain size to~2.1µm comparing that without water cooling.And the grain growth rate was reduced by artificial cooling out of extrusion die.Under the combination of two-stage cooling,the fine DRXed grains at sizing band were almost retained with average grain size of~2.3µm after the sheet out of extrusion die,and the unDRXed grains with high residual dislocation density accumulation were also reserved.The tensile tests results indicated that a good strength-ductility balance with a high ultimate tensile strength(319 MPa vs.412 MPa)and fracture elongation(19.9%vs.30.3%)were obtained.The strength enhancement was mainly owing to the grain refinement and local residual plastic strain reserved by the artificial cooling.The excellent ductility originated from fine DRXed microstructure and ED-tilt double peak texture.

Application of nanoparticles in the early diagnosis and treatment of tumors:current status and progress

Objective:Malignant tumors pose a serious threat to human life and health.Despite recent developments in modern medical techniques,the early diagnosis and treatment of tumors remain difficult due to their asymptomatic nature in the early stages of disease and the limitations in current clinical diagnostic methods.Advancements in nanotechnology,particularly in the area of multi-functional diagnostic nanomaterials,can help effectively resolve present inadequacies via concurrently achieving early diagnosis,image-guided intervention,and real-time monitoring and treatment of tumors.The development of nanomaterials and nanotechnology may also aid in the area of anti-cancer drug development by improving the safety and side-effect profile,as well as by enhancing the targeted specificity of the drugs,which are two of the long-standing challenges in Western medicine.The progress in the field of nanomaterials has also uncovered novel approaches for the clinical application of traditional Chinese medicine because the combination of traditional Chinese medicine components with nanoparticles overcomes various drawbacks,including poor water solubility,low bioavailability,and short half-life,of the former.Moreover,nanoparticles also enhance the biological effectiveness and targeted specificity of these medicines.In this review,we discuss the application of nanoparticles in the early diagnosis and treatment of tumors,through modern and traditional medicine.

Genesis and microscopic characteristics of tight reservoirs in the Fengcheng Formation, at the southern margin of the Mahu Sag

The tight reservoirs of the Fengcheng Formation at the southern margin of the Mahu Sag have strong heterogeneity due to the diversity in their pore types, sizes, and structures. The microscopic characteristics of tight reservoirs and the mechanisms that generate them are of significance in identifying the distribution of high-quality reservoirs and in improving the prediction accuracy of sweet spots in tight oil reservoirs. In this paper, high-pressure mercury intrusion (HPMI) and nuclear magnetic resonance (NMR) experiments were carried out on samples from the tight reservoirs in the study area. These experimental results were combined with cluster analysis, fractal theory, and microscopic observations to qualitatively and quantitatively evaluate pore types, sizes, and structures. A classification scheme was established that divides the reservoir into four types, based on the microstructure characteristics of samples, and the genetic mechanisms that aided the development of reservoir microstructure were analyzed. The results show that the lower limit for the tight reservoir in the Fengcheng Formation is Φ of 3.5% and K of 0.03 mD. The pore throat size and distribution span gradually decrease from Type I, through Type II and Type III reservoirs to non-reservoirs, and the pore type also evolves from dominantly intergranular pores to intercrystalline pores. The structural trend shows a decrease in the ball-stick pore-throat system and an increase in the branch-like pore-throat system. The dual effects of sedimentation and diagenesis shape the microscopic characteristics of pores and throats. The sorting, roundness, and particle size of the original sediments determine the original physical properties of the reservoir. The diagenetic environment of ‘two alkalinity stages and one acidity stage’ influenced the evolution of pore type and size. Although the cementation of authigenic minerals in the early alkaline environment adversely affected reservoir properties, it also alleviated the damage of the later compaction to some extent. Dissolution in the mid-term acidic environment greatly improved the physical properties of this tight reservoir, making dissolution pores an important reservoir space. The late alkaline environment occurred after large-scale oil and gas accumulation. During this period, the cementation of authigenic minerals had a limited effect on the reservoir space occupied by crude oil. It had a more significant impact on the sand bodies not filled with oil, making them function as barriers.

Restraining migration and dissolution of transition-metal-ions via functionalized separator for Li-rich Mn-based cathode with high-energy-density

Lithium-rich manganese-based materials(LRMs) are promising cathode for high-energy-density lithiumion batteries due to their high capacity,low toxicity,and low cost.However,LRMs suffer from serious voltage decay and capacity fade due to continual migration and dissolution of transition metal ions(TMs) during cycling process.Herein,a novel strategy is proposed to inhibit the TMs migration of LRMs through a modified separator by means of functionalized carbon coating layer,which depends on the chemical constraint of the abundant functional groups in the modified super P.In addition,it has been found that the dissolution of TMs can be restrained based on the Le Chatelier's principle.Moreover,the modified separator owns good wettability toward the electrolyte.As a result,the LRMs cathode with the modified separator delivers a high discharge capacity of 329.93 mA h g-1 at 0.1 C,and achieves good cyclic performance,the enhanced reaction kinetics and low voltage decay.Therefore,this work provides a new idea to promote the comprehensive electrochemical performances of Li-ion batteries with LRMs cathode through a strategy of separator modification.

Nature-inspired materials and designs for flexible lithium-ion batteries

Flexible lithium-ion batteries(FLBs)are of critical importance to the seamless power supply of flexible and wearable electronic devices.However,the simultaneous acquirements of mechanical deformability and high energy density remain a major challenge for FLBs.Through billions of years of evolutions,many plants and animals have developed unique compositional and structural characteristics,which enable them to have both high mechanical deformability and robustness to cope with the complex and stressful environment.Inspired by nature,many new materials and designs emerge recently to achieve mechanically flexible and high storage capacity of lithiumion batteries at the same time.Here,we summarize these novel FLBs inspired by natural and biological materials and designs.We first give a brief introduction to the fundamentals and challenges of FLBs.Then,we highlight the latest achievements based on nature inspiration,including fiber-shaped FLBs,origami and kirigami-derived FLBs,and the nature-inspired structural designs in FLBs.Finally,we discuss the current status,remaining challenges,and future opportunities for the development of FLBs.This concise yet focused review highlights current inspirations in FLBs and wishes to broaden our view of FLB materials and designs,which can be directly“borrowed”from nature.

Cellular senescence throws new insights into patient classification and pharmacological interventions for clinical management of hepatocellular carcinoma

BACKGROUND Cellular senescence,a state of stable growth arrest,is intertwined with human cancers.However,characterization of cellular senescence-associated phenotypes in hepatocellular carcinoma(HCC)remains unexplored.AIM To address this issue,we delineated cellular senescence landscape across HCC.METHODS We enrolled two HCC datasets,TCGA-LIHC and International Cancer Genome Consortium(ICGC).Unsupervised clustering was executed to probe tumor heterogeneity based upon cellular senescence genes.Least absolute shrinkage and selection operator algorithm were utilized to define a cellular senescence-relevant scoring system.TRNP1 expression was measured in HCCs and normal tissues through immunohistochemistry,immunoblotting and quantitative real-time polymerase chain reaction.The influence of TMF-regulated nuclear protein(TRNP)1 on HCC senescence and growth was proven via a series of experiments.RESULTS TCGA-LIHC patients were classified as three cellular senescence subtypes,named C1–3.The robustness and reproducibility of these subtypes were proven in the ICGC cohort.C2 had the worst overall survival,C1 the next,and C3 the best.C2 presented the highest levels of immune checkpoints,abundance of immune cells,and immunogenetic indicators.Thus,C2 might possibly respond to immunotherapy.C2 had the lowest somatic mutation rate,while C1 presented the highest copy number variations.A cellular senescence-relevant gene signature was generated,which can predict patient survival,and chemo-or immunotherapeutic response.Experimentally,it was proven that TRNP1 presented the remarkable upregulation in HCCs.TRNP1 knockdown induced apoptosis and senescence of HCC cells and attenuated tumor growth.CONCLUSION These findings provide a systematic framework for assessing cellular senescence in HCC,which decode the tumor heterogeneity and tailor the pharmacological interventions to improve clinical management.

Ordered Arrangement of Micro-beads in Single Line by Micromolding in Capillaries

An effective procedure was demonstrated to arrange spherical micro-beads into ordered, long, line-shape arrays by means of ＂micromolding in capillaries＂ in soft lithography. Polystyrene （PS） micro-beads with 2-3 mm of diameter were used as units and arranged by molding in continuous micro-channels formed by the conformal contact between a glass substrate and an elastomeric stamp with micrometer-scale line patterns on the surface. An aqueous emulsion of PS micro-beads filled these channels by capillary action and was allowed to solidify. The stamp was then removed. The PS micro-beads could be assembled into a string of long line-shape arrays, and the strings were then joined by heating them to their softening temperature. In order to separate the PS micro-bead string from the substrate, the glass was covered with a thin layer of A1 or polymethyl methacrylate. After the A1 layer was dissolved, the string of PS micro-beads would be released. A string of micrometer scale PS beads can be used as a simple and direct ＂model＂ of a real macromolecular chain. It is hopeful to show an analogue with the condensed process of real macromolecules in a mesoscopic scale using the ＂string of PS micro-beads＂.

Variability:Human nature and its impact on measurement and statistical analysis

The world is colorful,different,and diverse!So are humans.Human variability refers to the variability among individuals,which could be the variability of a human trait(e.g.,body fat percent),or the difference in the response of a trait to a simulation(e.g.,losing or not losing weight when facing the same intervention).

SOFFLFM:Super-resolution optical fluctuation Fourierlight-field microscopy

Fourier light-field microscopy(FLFM)uses a microlens aray(MLA)to segment the Fourierplane of the microscopic objective lens to generate multiple two-dimensional perspective views,thereby reconstructing the threedimensional(3D)structure of the sample using 3D deconvo-lution calculation without scanning.However,the resolution of FLFM is stil limited by dif-fraction,and furthermore,it is dependent on the aperture division.In order to improve itsresolution,a super-resolution opticai fuctuation Fourier light-field microscopy(SOFFLFM)wasproposed here,in which the super-resolution optical fluctuation imaging(SOFI)with the abilityof super-resolution was introduced into FLFM.SOFFLFM uses higher-order cumulants statis-tical analysis on an image sequence collected by FLFM,and then carries out 3D deconvolutioncalculation to reconstruct the 3D structure of the sample.The theoretical basis of SOFFLFM onimproving resolution was explained and then verified with the simulations.Simulation resultsdemonstrated that SOFFLFM improved the lateral and axial resolution by more than V2 and 2times in the second-and fourth-order accumulations,compared with that of FLFM.
