3First episode psychosis with extrapyramidal signs prior to antipsychotic drug treatment显示文摘Extrapyramidal movement disorders are common in chronic schizophrenia, and may be an intrinsic feature of the illness as well as related to antipsychotic drug treatment. Similar dysfunctions at illness onset may have implications for outcome, and for under- standing the mechanisms of illness. The objectives were to examine the clinical correlates of pre-treatment movement disorders at first episode of psychosis, and determine associations with neuropsychological function and striatal structure. Never medicated subjects were recruited from consecutive admissions to Early Psychosis Programs with defined catchment areas in Hong Kong, China, and Halifax, Canada. Standardized clinical, neuropsychological and brain imaging assessments were carried out at baseline and following acute and long term treatment with typical or atypical antipsychotic drugs. At the Hong Kong site, we studied 84 subjects with first episode psychosis (n = 10 with EPS). At the Halifax site, we studied 40 subjects with first episode psychosis (n = 17 with EPS), and 23 healthy comparison subjects. Subjects with movement disorders prior to treatment (EPS+) had higher total PANSS scores at baseline (mean elevation 19.9% Hong Kong, P = 0.016; 14.7% Halifax, P = 0.049). In subjects treated with atypical antipsychotics (all Halifax), EPS+ status at baseline predicted more movement disorders at long term follow up (P = 0.0005). In both cohorts, EPS+ subjects had poorer acute symptomatic treatment response assessed with the PANSS (Hong Kong P = 0.005; Halifax P = 0.017). Neuropsychological impairment related to executive dysfunction appeared greater in a small sam- ple of EPS+ subjects (Hong Kong, effect size 0.26-0.27, P < 0.05). Caudate volumes were 4.5% larger in EPS+ compared with EPS-subjects (Halifax P = 0.042), and correlations between striatal volumes and age were different in the EPS+ group. In conclu- sion, pre-treatment EPS is present in a substantial minority of subjects with first episode psychosis, appears to persist at long term follow up, and is associated with poorer response of symptoms to treatment. Selective impairment of executive function and stria- tal enlargement provides evidence of abnormalities of brain function and structure associated with this aspect of early psychosis.HONER William G LANG Donna J KOPALA Lili C MACEWAN G William SMITH Geoffrey N CHEN Eric Y H CHAN Raymond C K 2011Chinese Science Bulletin2011,56,32:1
43D Printing of Biodegradable Polymer Vascular Stents:A Review显示文摘Biodegradable polymer vascular stents(BPVSs)have been widely used in percutaneous coronary interventions for the treatment of coronary artery diseases.The development of BPVSs is an integrated process that combines material design/selection,manufacturing,and performance characterization.Three-dimensional(3D)printing technology is a powerful tool for polymer stent fabrication.Current review studies have focused primarily on the material and structural design of polymer stents but have failed to comprehensively discuss different 3D printing approaches and stent characterization techniques.In this paper,we address these shortcomings by discussing 3D printing methods and their application in BPVSs.First,some commonly used 3D printing methods(including material extrusion,vat polymerization,and powder bed fusion)and potential 3D printing strategies(including material jetting and binder jetting)for fabricating BPVSs are discussed;furthermore,the main post-treatments are summarized.Then,techniques to characterize the morphology,mechanical properties,and biological prop-erties of the printed BPVSs are introduced.Subsequently,representative commercial BPVSs and lab-grade BPVSs are compared.Finally,based on the limitations of stent printing and characterization processes,future perspec-tives are proposed,which may help develop new techniques to fabricate more customized stents and accurately evaluate their performance.Weijian Hua Weiliang Shi Kellen Mitchell Lily Raymond Ryan Coulter Danyang Zhao Yifei Jin 2022Chinese Journal of Mechanical Engineering(Additive Manufacturing Frontiers)2022,1,2:0
5Tumor heterogeneity in VHL drives metastasis in clear cell renal cell carcinoma显示文摘Loss of function of the von Hippel-Lindau(VHL)tumor suppressor gene is a hallmark of clear cell renal cell carcinoma(ccRCC).The importance of heterogeneity in the loss of this tumor suppressor has been under reported.To study the impact of intratumoral VHL heterogeneity observed in human ccRCC,we engineered VHL gene deletion in four RCC models,including a new primary tumor cell line derived from an aggressive metastatic case.The VHL gene-deleted(VHL-KO)cells underwent epithelial-to-mesenchymal transition(EMT)and exhibited increased motility but diminished proliferation and tumorigenicity compared to the parental VHL-expressing(VHL+)cells.Renal tumors with either VHL+or VHL-KO cells alone exhibit minimal metastatic potential.Combined tumors displayed rampant lung metastases,highlighting a novel cooperative metastatic mechanism.The poorly proliferative VHL-KO cells stimulated the proliferation,EMT,and motility of neighboring VHL+cells.Periostin(POSTN),a soluble protein overexpressed and secreted by VHL non-expressing(VHL−)cells,promoted metastasis by enhancing the motility of VHL-WT cells and facilitating tumor cell vascular escape.Genetic deletion or antibody blockade of POSTN dramatically suppressed lung metastases in our preclinical models.This work supports a new strategy to halt the progression of ccRCC by disrupting the critical metastatic crosstalk between heterogeneous cell populations within a tumor.Junhui Hu Ping Tan Moe Ishihara Nicholas ABayley Shiruyeh Schokrpur Jeremy GReynoso Yangjun Zhang Raymond JLim Camelia Dumitras Lu Yang Steven MDubinett Parmjit SJat Jacques Van Snick Jiaoti Huang Arnold IChin Robert MPrins Thomas GGraeber Hua Xu Lily Wu 2023Signal Transduction and Targeted Therapy2023,8,5:0
6Direct ink writing to fabricate porous acetabular cups from titanium alloy显示文摘Acetabular cups,which are among themost important implants in total hip arthroplasty,are usually made from titanium alloys with high porosity and adequate mechanical properties.The current three-dimensional(3D)printing approaches to fabricate customized acetabular cups have some inherent disadvantages such as high cost and energy consumption,residual thermal stress,and relatively low efficiency.Thus,in this work,a direct ink writing method was developed to print a cup structure at room temperature,followed by multi-step heat treatment to form microscale porous structure within the acetabular cup.Our method is facilitated by the development of a self-supporting titanium-6 aluminum-4 vanadium(Ti64)ink that is composed of Ti64 particles,bentonite yield-stress additive,ultraviolet curable polymer,and photo-initiator.The effects of Ti64 and bentonite concentrations on the rheological properties and printability of inks were systematically investigated.Moreover,the printing conditions,geometrical limitations,and maximum curing depth were explored.Finally,some complex 3D structures,including lattices with different gap distances,honeycomb with a well-defined shape,and an acetabular cup with uniformly distributed micropores,were successfully printed/fabricated to validate the effectiveness of the proposed method.Naima Valentin Weijian Hua Ashish K.Kasar Lily Raymond Pradeep L.Menezes Yifei Jin 2023Bio-Design and Manufacturing2023,6,2:0
