2Preoperative diagnosis of malignant pulmonary nodules in lung cancer screening with a radiomics nomogram显示文摘Background:Lung cancer is the most commonly diagnosed cancer worldwide.Its survival rate can be significantly improved by early screening.Biomarkers based on radiomics features have been found to provide important physiological information on tumors and considered as having the potential to be used in the early screening of lung cancer.In this study,we aim to establish a radiomics model and develop a tool to improve the discrimination between benign and malignant pulmonary nodules.Methods:A retrospective study was conducted on 875 patients with benign or malignant pulmonary nodules who underwent computed tomography(CT)examinations between June 2013 and June 2018.We assigned 612 patients to a training cohort and 263 patients to a validation cohort.Radiomics features were extracted from the CT images of each patient.Least absolute shrinkage and selection operator(LASSO)was used for radiomics feature selection and radiomics score calculation.Multivariate logistic regression analysis was used to develop a classification model and radiomics nomogram.Radiomics score and clinical variables were used to distinguish benign and malignant pulmonary nodules in logistic model.The performance of the radiomics nomogram was evaluated by the area under the curve(AUC),calibration curve and Hosmer-Lemeshow test in both the training and validation cohorts.Results:A radiomics score was built and consisted of 20 features selected by LASSO from 1288 radiomics features in the training cohort.The multivariate logistic model and radiomics nomogram were constructed using the radiomics score and patients’age.Good discrimination of benign and malignant pulmonary nodules was obtained from the training cohort(AUC,0.836;95%confidence interval[CI]:0.793-0.879)and validation cohort(AUC,0.809;95%CI:0.745-0.872).The Hosmer-Lemeshow test also showed good performance for the logistic regression model in the training cohort(P=0.765)and validation cohort(P=0.064).Good alignment with the calibration curve indicated the good performance of the nomogram.Conclusions:The established radiomics nomogram is a noninvasive preoperative prediction tool for malignant pulmonary nodule diagnosis.Validation revealed that this nomogram exhibited excellent discrimination and calibration capacities,suggesting its clinical utility in the early screening of lung cancer.Ailing Liu Zhiheng Wang Yachao Yang Jingtao Wang Xiaoyu Dai Lijie Wang Yuan Lu Fuzhong Xue 2020Cancer Communications2020,40,1:22
3Nerve growth factor pretreatment against glutamate-induced hippocampal neuronal injury Action mechanism of phosphatase and tensin homologue deleted on chromosome 10显示文摘BACKGROUND: Nerve growth factor (NGF) attenuates glutamate-induced injury to hippocampal neurons, and the human tumor suppressor gene phosphatase and tensin homologue deleted on chromosome 10 (PTEN) promotes neuronal apoptosis. However, effects of PTEN in NGF-mediated neuroprotection against glutamate excitotoxicity remain poorly understood. OBJECTIVE: To investigate the relationship between NGF inhibition of glutamate-induced injury and PTEN. DESIGN, TIME AND SETTING: The randomized, controlled, in vitro study was performed at the Department of Pathophysiology, Medical School of Nantong University, China from October 2007 to March 2008. MATERIALS: Glutamate, NGF, 4, 6-diamidino-2-phenyl-indolediacetate, 3-[4, 5-dimethylthiazol-2-yl]- 2, 5-diphenyl tetrazoliumbromide (MTT), and lactate dehydrogenase kit (Sigma, USA), fluorescence microscope and inverted phase contrast microscope (Olympus, Japan) were used in this study. METHODS: Hippocampal neurons were obtained from newborn (< 24 hours) Sprague Dawley rats and cultured for 7 days. The control group was not treated with any intervention factor, the glutamate group was treated with glutamate (0.2 mmol/L), and NGF groups were treated with NGF (10, 50, 100, and 200 μg/L, respectively) prior to glutamate treatment. MAIN OUTCOME MEASURES: The MTT and lactate dehydrogenase assays were applied to evaluate viability of hippocampal neurons. Morphological changes in hippocampal neurons were observed using an inverted phase-contrast microscope, and neuronal apoptosis was detected by 4, 6-diamidino-2-phenyl-indolediacetate staining. PTEN mRNA and protein expression were measured by reverse transcription-polymerase chain reaction and Western blot analysis, respectively. RESULTS: Glutamate (0.2 mmol/L) induced significantly decreased neuronal viability and greater lactate dehydrogenase efflux compared with the control group (P < 0.01). However, compared with the glutamate group, cell viability significantly increased and lactate dehydrogenase efflux decreased in the NGF group with increasing NGF concentrations (P < 0.05 or P < 0.01). The apoptotic ratio and PTEN mRNA and protein expression decreased in the NGF group compared with the glutamate group (P < 0.01). CONCLUSION: Pretreatment with NGF exerted neuroprotective effects against glutamate-induced injury, partially through inhibition of PTEN expression and neuronal apoptosis.Yae Hu Jiahui Mao Yan Zhu Ailing Zhou 2010Neural Regeneration Research2010,5,1:12

5Toll-like receptor 4-mediated signaling participates in apoptosis of hippocampal neurons显示文摘The phosphatidylinositol 3 kinase(PI3K)/protein kinase B(AKT)signaling pathway is considered important for cell survival and has been shown to mediate various anti-apoptotic biological effects.This study explored the role of the Toll-like receptor 4(TLR4)-mediated PI3K/AKT-glycogen synthase kinase 3β(GSK-3β)signaling pathways in lipopolysaccharide-induced apoptosis in a primary culture of hippocampal neurons.Results demonstrated that the apoptotic ratio of hippocampal neurons stimulated by lipopolysaccharide was significantly higher compared with the control group.Both the expression of P-AKTSer473and P-GSK-3βSer9in hippocampal neurons stimulated by lipopolysaccharide decreased compared with the control,while the level of active Caspase-3 and the ratio of Bax/Bcl-2 were significantly increased.The level of active Caspase-3 and the ratio of Bax/Bcl-2 in hippocampal neurons treated with TLR4 antibody or the GSK-3βinhibitor,LiCl,decreased before intervention with lipopolysaccharide,but increased after treatment with the AKT inhibitor,LY294002.These findings suggest that the TLR4-PI3K/AKT-GSK3βsignaling pathway may be involved in lipopolysaccharide-induced apoptosis of hippocampal neurons.Yue He Ailing Zhou Wei Jiang 2013Neural Regeneration Research2013,8,29:8
6Hierarchical composite of biomass derived magnetic carbon framework and phytic acid doped polyanilne with prominent electromagnetic wave absorption capacity显示文摘To solve the electromagnetic pollution,herein,a CoFe_(2)O_(4)/C/PANI composite was developed by a green route,which was constructed with spinel of metal oxide,graphitized carbon and conductive polymer composites.Benefiting from the designable interfaces and increased dipoles,the microwave dielectric response capability can be boosted significantly and resulted in the enhanced microwave absorbing performance.As revealed by the reflection loss curve,the minimum reflection loss(RLmin) reached-51.81 dB at 12.4 GHz under a matched thickness of 2.57 mm.At 2.5 mm,the effective absorbing band covered 8.88 GHz,suggesting the desirable wideband feature.In our case,the method of utilization of a novel green way to fabricate multiple-component EM absorber can be a promising candidate for high-performance EM absorber.Tianqi Hou Zirui Jia Ailing Feng Zehua Zhou Xuehua Liu Hualiang Lv Guanglei Wu 2021Journal of Materials Science & Technology2021,,9:8
7Isolation,Screening,and Optimization of the Fermentation Conditions of Highly Cellulolytic Bacteria from the Hindgut of Holotrichia parallela Larvae(Coleoptera:Scarabaeidae)显示文摘From the hindgut contents of Holotrichia parallela larvae,207 aerobic and facultatively anaerobic cellulolytic bacterial isolates were obtained.These bacterial isolates were assigned to 21 genotypes by amplified ribosomal DNA restriction analysis(ARDRA).A partial 16 S rDNA sequence analysis and standard biochemical and physiological tests were used for the assignment of the 21 representative isolates.Our results show that the cellulolytic bacterial community is dominated by the Proteobacteria(70.05%),followed by the Actinobacteria(24.15%),the Firmicutes(4.35%),and the Bacteroidetes(1.45%).And among the cellulolytic bacteria,some isolates,Siphonobacter aquaeclarae,Cellulosimicrobium funkei,Citrobacter freundii,Pseudomonas nitroreducens,and so on,are reported to be cellulolytic for the first time in this study.Among these isolates,a novel bacterium,designated Pseudomonas sp.HP207,with the highest endoglucanase productivity was selected for further study.The production of the endoglucanase was optimized by varying various physical culture conditions using a submerged fermentation method.Under the optimized fermentation conditions,the maximum endoglucanase activity of 1.432 U mL-1 in bacterial cultures was obtained,higher than those of the most widely studied bacteria and fungi,which are the attractive candidates for the commercial producer of cellulase.And the crude endoglucanase enzyme was also highly thermostable;approximately 55% of the original activity was maintained after pretreatment at 70°C for 1 h.Thus,from the present study,the bacterium can be added up to the database of cellulolytic bacteria,the scarab gut is an attractive source for the study of novel cellulolytic microorganisms and enzymes useful for cellulose degradation.Ping Sheng Shengwei Huang Qi Wang Ailing Wang Hongyu Zhang 2012华中昆虫研究2012,,1:7
8Oxymatrine reduces neuroinflammation in rat brain A signaling pathway显示文摘Cerebral neuroinflammation models were established by injecting 10 μg lipopolysaccharide into the hippocampus of male Sprague-Dawley rats. The rats were treated with an intraperitoneal injection of 120, 90, or 60 mg/kg oxymatrine daily for three days prior to the lipopolysaccharide injection. Twenty-four hours after model induction, the hippocampus was analyzed by real-time quantitative PCR, and the cerebral cortex was analyzed by enzyme-linked immunosorbent assay and western blot assay. The results of the enzyme-linked immunosorbent assay and the real-time quantitative PCR showed that the secretion and mRNA expression of the pro-inflammatory cytokines interleukin-1β and tumor necrosis factor-α were significantly decreased in the hippocampus and cerebral cortex of model rats treated with oxymatrine. Western blot assay and real-time quantitative PCR analysis indicated that toll-like receptor 4 mRNA and protein expression were significantly decreased in the groups receiving different doses of oxymatrine. Additionally, 120 and 90 mg/kg oxymatrine were shown to reduce protein levels of nuclear factor-κB p65 in the nucleus and of phosphorylated IκBα in the cytoplasm of brain cells, as detected by western blot assay. Experimental findings indicate that oxymatrine may inhibit neuroinflammation in rat brain via downregulating the expression of molecules in the toll-like receptor 4/nuclear factor-κB signaling pathway.Jiahui Mao Yae Hu Ailing Zhou Bing Zheng Yi Liu Yueming Du Jia Li Jinyang Lu Pengcheng Zhou 2012Neural Regeneration Research2012,7,30:7
9Mitochondria-targeted antioxidant peptide SS-31 mediates neuroprotection in a rat experimental glaucoma model显示文摘To investigate the neuroprotective effects of the mitochondria-targeted antioxidant Szeto-Schiller peptide 31 (SS-31) in a rat experimental glaucoma model, SS-31 was intraperitoneally (IP) injected into Sprague-Dawley rats, followed by intracameral injection of polystyrene microspheres to induce elevated intraocular pressure (IOP). After 6 weeks, electroretinography (ERG) and flash visual-evoked potentials (F-VEPs) were recorded to assess retinal function. Hematoxylin-eosin staining was performed on retinal cross-sections to measure ganglion cell complex (GCC) thickness. Apoptotic retinal cells were assessed by TUNEL staining. Brn3a-positive retinal ganglion cells (RGCs) were counted in retinal flat mounts via immunofluorescence. The retinal total SOD, SOD2, and MDA expression levels were assessed in retinal tissue homogenates. The cyt c, Baxz and Bcl-2 protein levels in rat retinas were detected by western blot analysis. Bax and Bcl-2 expressions were also evaluated using immunohistochemistry in paraffinized sections. Our results showed that the rats that received microsphere injection developed elevated IOP. SS-31 ameliorated the reductions in the a- and b-wave amplitudes on ERG and the F-VEP amplitude in glaucomatous eyes. GCC thickness was preserved, TUNEL-positive cells were decreased in the retina, and Brn3a-positive RGCs were in creased in the SS-31-treated glaucoma group compared with those in the non-treated glaucoma group. SS-31 significantly reduced MDA levels and increased SOD2 levels after glaucoma induction. Significant suppression of cyt c release, upregulation of Bcl-2, and downregulation of Bax were observed following SS-31 administration. In summary, SS-31 exerts neuroprotective effects in this experimental glaucoma model by inhibiting mitochondrial dysfunction and therefore represents a promising therapeutic agent for glaucoma.Xiaoqiong Wu Yu Pang Zhilin Zhang Xiabin Li Chao Wang Yingqing Lei Ailing Li Ling Yu Jian Ye 2019Acta Biochimica et Biophysica Sinica2019,51,4:7
10Co-Production of Lipids, Eicosapentaenoic Acid, Fucoxanthin, and Chrysolaminarin by Phaeodactylum tricornutum Cultured in a Flat-Plate Photobioreactor Under Varying Nitrogen Conditions显示文摘The marine diatom Phaeodactylum tricornutum is a polymorphological, ecologically significant, and well-studied model of unicellular microalga. This diatom can accumulate diverse important metabolites. Herein, we cultured P. tricornutum in an internally installed tie-piece flat-plate photobioreactor under 14.5 m mol L^(-1)(high nitrogen, HN) and 2.9 m mol L^(-1)(low nitrogen, LN) of KNO_3 and assessed its time-resolved changes in biochemical compositions. The results showed that HN was inductive to accumulate high biomass(4.1 g L^(-1)). However, the LN condition could accelerate lipid accumulation in P. tricornutum. The maximum total lipid(TL) content under LN was up to 42.5% of biomass on day 12. Finally, neutral lipids(NLs) were 63.8% and 75.7% of TLs under HN and LN, respectively. The content of EPA ranged from 2.3% to 1.5% of dry weight during the growth period under the two culture conditions. Peak volumetric lipid productivity of 128.4 mg L^(-1)d^(-1) was achieved in the HN group(on day 9). The highest volumetric productivity values of EPA, chrysolaminarin, and fucoxanthin were obtained in the exponential phase(on day 6) under HN, which were 9.6, 93.6, and 4.7 mg L^(-1)d^(-1), respectively. In conclusion, extractable amounts of lipids, EPA, fucoxanthin, and chrysolaminarin could be obtained from P. tricornutum by regulating the culture conditions.GAO Baoyan CHEN Ailing ZHANG Wenyuan LI Aifen ZHANG Chengwu 2017Journal of Ocean University of China2017,16,5:6
11An App knock-in rat model for Alzheimer’s disease exhibiting Aβand tau pathologies,neuronal death and cognitive impairments显示文摘A major obstacle in Alzheimer’s disease(AD)research is the lack of predictive and translatable animal models that reflect disease progression and drug efficacy.Transgenic mice overexpressing amyloid precursor protein(App)gene manifest non-physiological and ectopic expression of APP and its fragments in the brain,which is not observed in AD patients.The App knock-in mice circumvented some of these problems,but they do not exhibit tau pathology and neuronal death.We have generated a rat model,with three familiar App mutations and humanized Aβsequence knocked into the rat App gene.Without altering the levels of full-length APP and other APP fragments,this model exhibits pathologies and disease progression resembling those in human patients:deposit of Aβplaques in relevant brain regions,microglia activation and gliosis,progressive synaptic degeneration and AD-relevant cognitive deficits.Interestingly,we have observed tau pathology,neuronal apoptosis and necroptosis and brain atrophy,phenotypes rarely seen in other APP models.This App knock-in rat model may serve as a useful tool for AD research,identifying new drug targets and biomarkers,and testing therapeutics.Keliang Pang Richeng Jiang Wei Zhang Zhengyi Yang Lin-Lin Li Makoto Shimozawa Simone Tambaro Johanna Mayer Baogui Zhang Man Li Jiesi Wang Hang Liu Ailing Yang Xi Chen Jiazheng Liu Bengt Winblad Hua Han Tianzi Jiang Weiwen Wang Per Nilsson Wei Guo Bai Lu 2022Cell Research2022,32,2:6
12Regulation of alveolar type 2 stem/progenitor cells in lung injury and regeneration显示文摘The renewal of lung epithelial cells is normally slow unless the lung is injured.The resident epithelial stem cells rapidly proliferate and differentiate to maintain lung structure and function when the lung is damaged.The alveolar epithelium is characterized by alveolar type 1(AT1)and alveolar type 2(AT2)cells.AT2 cells are the stem cells for alveoli,as they can both self-renew and generate AT1 cells.Abnormal proliferation and regulation of AT2 cells will lead to serious lung diseases including cancers.In this review,we focused on the alveolar stem/progenitor cells,the key physiological function of AT2 cells in lung homeostasis and the complicated regulation of AT2 cells in the repairing processes after lung injury.Ailing Wu Hai Song 2020Acta Biochimica et Biophysica Sinica2020,52,7:6

14Growth Characteristics and Kinetics of Niobium Carbide Coating Obtained on AISI 52100 by Thermal-reactive Diffusion Technique显示文摘Niobium carbide coating was produced by thermal-reactive diffusion technique on AISI 52100 steel in salt bath at 1 123 K, 1 173 K, and 1 223 K for 1, 2, 4, and 6 hours. The salt consisted of borax, sodium fl uoride, boron carbide, and niobium pentoxide. The presence of NbC phase on the steel surface was confi rmed by X-ray diffraction analysis. Microscopic observation showed that niobium carbide coating formed on the substrate was smooth and compact. There was a distinct and fl at interface between the coating and substrate. The micro-hardness of niobium carbide coating was 2892±145HV. The thickness of coating ranged from 1.6 μm to 14μm. The forming kinetics of niobium carbide coating was revealed. Moreover, a contour diagram derived from experimental data was graphed for correct selection of process parameters. Some mathematical equations were built for predicting the coating thickness with predetermined processing temperature and time. The results showed that these mathematical equations are very practical as well as the kinetics equation.严绍进 王洪福 SUN Qikun HE Peng PANG Chengang WANG Huachang WANG Ailing 2014Journal of Wuhan University of Technology(Materials Science)2014,29,4:5
15Studies on Lung Cancer Angiogenesis-Application of Interventional Therapy (A Report of 56 Cases)显示文摘OBJECTIVE To investigate the significance of angiogenesis of lung cancer, in order to provide a scientific basis for interventional therapy. METHODS Double-phase enhancementscanning spiral CT and DSA were performed in 56 pathologically confi rmed lung cancer cases, in order to evaluate angiogenesis of the tumors. The patients included 36 males and 20 females, with ages ranging from 33 to 76 years (average of 53). Assessments and indexes for SCT and DSA examinations were as follows: a) Peak value (PV) of the cancerous focus was the difference between the maximum CT value after enhancement and the CT value of a plain scan; b) The abnormally distorted and expanded new vessels of the cancerous focus which could be macroscopically discriminated; c) DSA staining of the focus of cancer was sparse, grid-like and dense. Chemotherapy and embolotherapy via the bronchial artery (interventional therapy) were conducted. Radiotherapy was added for some of the solid tumors with a diameter exceeding 4 cm. RESULTS a) There were 25 cases with a central-type lesion, among which 4 were small cell lung cancers (SCLC) and 21 non-small cell lung cancers (NSCLC). The cases with a peripheral location accounted for 31 of the total, with a maximum diameter of 1.5 to 13.5 cm and a median of 4.2 cm, including 5 small cell lung cancers and 26 NSCLC cases. b) The reinforced PVs of the cancerous foci were as follows: The PV ranged from 45 to 70 Hu in 34 cases, 25 to 45 Hu in 19, and 10 to 25 Hu in 3. Sparse DSA staining occurred in 3 cases, there was uneven grid-like staining in 22 and dense staining in 31; c) The interventional therapy via the bronchial artery was con-ducted twice in 5 cases with the SCLC, and three times in 4 SCLC cases. For 3 of the latter cases, a dose of 5,000 to 7,000 cGy radiation therapy was added during the interventional treatment. Complete remissions (CR) were seen in 88.9% of the cases (8/9) and partial remission (PR) in 11.1% (1/9). Interventional therapy was conducted twice in 8 cases with NSCLC and three times in 30 with NSCLC and four times in 9 cases. Among the total cases, 13 received radiotherapy during interventional therapy, with a radiation dose of 5,000-7,000 cGy; The CR rate was 78.7% (37/47), PR was 14.9% (7/47) and the rate of non-remission was 6.4% (3/47). CONCLUSION Using imaging technology, analysis of angiogenesis of lung cancers was employed to accurately detect and quantify angiogenesis. This analysis was combined for interventional therapy, using embolizing agents and large doses of the anti-tumor drugs and angiogenesis inhibitors. The agents were selectively delivered into the tumor vessels to eliminate the primary tumor, in order to depress distant metastases and thus enhance the curative effect of the therapy.Qiang Zhang Jun Guo Hailong Qian Baoqi Shi Jigang Zhang Chunjing Li Ailing Yang Zhuang Tian Baotou No. 7 Hospital Department of Radiol-ogy, Baotou Cancer Hospital, Baotou 014030, Inner Mongolia Autonomous Region, China. 2007Chinese Journal of Clinical Oncology2007,4,1:5
16Photoluminescence and defect evolution of nano-ZnO thin films at low temperature annealing显示文摘Nano-ZnO thin films composed of nanoparticles with sizes of 10-16 nm on silicon substrates at low temperature were prepared by sol-gel method.By placing the nano-ZnO thin films at room temperature or annealing at 100°C in air for 10 h intermittently,within a total 70 h annealing time,the evolution of PL spectra of the nano-ZnO thin films were studied in detail.As the annealing time increases,the PL peaks shift from violet to blue and green bands.The PL peaks at violet and blue bands decrease with the annealing time,but the PL peaks at green band are opposite.The PL spectra are related to the defects in the nano-ZnO thin films.The PL peaks positioned at 430 nm are mainly related to defects of zinc interstatials(Zni),oxygen vacancies and(Vo);the ones at 420 nm to oxygen interstitials(Oi),Zinc vacancies(Vzn),Zni ;and the ones at 468 nm to Vzn,Zni,and charged oxygen interstatials(Vo+).The green luminescence is related to Oi,Vo and Zni.The evolutions of PL spectra and the defects are also related to the concentrations of Zn in the thin films,the thicknesses of the films and the annealing time.For the films with 0.5 M and 1.0 M Zn concentrations,after 20 h and 30 h annealing in air at 100°C,respectively,either placing them in air at room temperature or continuing anneal in air at 100°C,the PL spectra are stable.Under the low temperature annealing,Zni decreases with the annealing time,and Oi increases.Sufficient Oi favors to keep the nano-ZnO thin films stable.This result is important to nano-ZnO thin films as electron transport layers in inverted or tandem organic solar cells.YANG AiLing YANG Yun ZHANG ZhenZhen BAO XiChang YANG RenQiang LI ShunPin SUN Liang 2013Science China(Technological Sciences)2013,56,1:5

18Tuning the intermolecular interaction of A_(2)-A_(1)-D-A_(1)-A_(2) type non-fullerene acceptors by substituent engineering for organic solar cells with ultrahigh V_(OC) of ~1.2 V显示文摘For non-fullerene acceptors(NFAs)with linear A_(2)-A_(1)-D-A_(1)-A_(2) backbone,there are three kinds of possible intermolecular interaction,A_(1)-A_(1),A_(1)-A_(2) and A_(2)-A_(2) stacking.Hence,it is a huge challenge to control this interaction and investigate the effect of intermolecular stacking model on the photovoltaic performance.Here,we adopt a feasible strategy,by utilizing different substituent groups on terminal A2 unit of dicyanomethylene rhodanine(RCN),to modulate this stacking model.According to theoretical calculation results,the molecule BTA3 with ethyl substituent packs via heterogeneous interaction between A_(2) and A_(1) unit in neighboring molecules.Surprisingly,the benzyl group can effectively transform the aggregation of BTA5 into homogeneous packing of A_(2)-A_(2) model,which might be driven by the strong interaction between benzyl and A1(benzotriazole)unit.However,different with benzyl,phenyl end group impedes the intermolecular interaction of BTA4 due to the large steric hindrance.When using a BTA-based D-π-A polymer J52-F as donor according to“Same-A-Strategy”,BTA3-5 could achieve ultrahigh open-circuit voltage(VOC)of 1.17–1.21 V.Finally,BTA5 with benzyl groups realized an improved power conversion efficiency(PCE)of 11.27%,obviously higher than that of BTA3(PCE=9.04%)and BTA4(PCE=5.61%).It is also worth noting that the same trend can be found when using other four classic p-type polymers of P3HT,PTB7,PTB7-Th and PBDB-T.This work not only investigates the intermolecular interaction of A_(2)-A_(1)-D-A_(1)-A_(2) type NFAs for the first time,but also provides a straightforward and universal method to change the interaction model and improve the photovoltaic performance.Xiaochen Wang Ailing Tang Jing Yang Mengzhen Du Jianfeng Li Gongqiang Li Qiang Guo Erjun Zhou 2020Science China Chemistry2020,63,11:5

20Breast cancer-specific serum peptide profiles显示文摘Early detection of breast cancer is paramount to successful clinical therapy. Yet, early-stage breast cancer lacks specific symptoms or biomarkers. With the emerging of the mass spectrometric (MS) -based signatures as biomarkers, we investigated breast cancer-related serum profile pattern through class prediction and independent validation, and used Fourier transfer MS to identify breast cancer signature. We now show a distinctive serum peptide pattern that discriminates breast cancer from healthy controls with 93.2% sensitivity and 95.4% specificity. m/z 5901.70 and 4465.74 of ion fragment of FPA and alpha1-antichymotrypsin are found in the signatures that predominantly discriminate breast cancer from healthy individuals. These novel findings identify an MS-based serum peptide pattern of breast cancer that may have direct clinical utility in future.WANG Na WEN XinYu WANG Jie LI AiLing LI WeiHua LI Tao Li Yan ZHANG XueMin WANG HongXia YANG SongCheng ZHOU Tao GONG WeiLi TIAN YaPing HE Kun 2009Chinese Science Bulletin2009,54,3:4
