| 1 | THE STRUCTURE CONTROL OF ALUMINUM FOAMS PRODUCED BY POWDER COMPACTED FOAMING PROCESS显示文摘A new technique, powder compact foaming process for the production of aluminum foams has been studied in this article. According to this method, the aluminum powder is mixed with a powder foaming agent (TiH2). Subsequent to mixing, the powder blend is hot compacted to obtain a dense semi-finished product. Upon heating to temperatures within the range of the melting point, the foaming agent decomposes to evolve gas and the semi-finished product expands into a porous cellular aluminum. Foaming process is the key in this method. Based on experiments, the foaming characteristics were mainly analyzed and discussed. Experiments show that the aluminum-foam with closed pores and a uniform cell structure of high porosity can be obtained using this method by adjusting the foaming parameters: the content of foaming agent and foaming temperature. | X.H.You F.

| 2 | ^(68)Gallium-labelled PSMA-PET/CT as a diagnostic and clinical decision-making tool in Asian prostate cancer patients following prostatectomy显示文摘Objective: Prostate cancers(PCa) in Asian individuals are molecularly distinct from those found in their Caucasian counterparts.There is no risk stratification tool for Asian men with rapid biochemical recurrence(BCR) following radical prostatectomy(Rad P). This study aims to assess the detection rate of ^(68)Ga-prostate-specific membrane antigen-positron emission tomography/computed tomography(PSMA-PET/CT) for diagnosis of clinical recurrence and as a treatment decision making tool in Asian patients with BCR post-Rad P.Methods: ^(68)Ga PSMA-PET and CT body with/without bone scan [conventional workup(CWU)] were performed in 55 Asian patients with BCR within 36 months post-Rad P. Two blinded reviewers assessed the images. Detection rates of ^(68)Ga PSMAPET/CT were evaluated, and impact on management was reviewed by comparison with CWU.Results: Median time to BCR post-Rad P was 8.1 months. Detection rate for ^(68)Ga PSMA-PET/CT was 80%(44/55). A positive scan was significantly associated with increasing prostate-specific antigen(PSA) level [odds ratio(OR) = 1.13(95% CI 1.05–1.30), P =0.017], but not with higher Gleason grade or shorter PSA doubling time. Compared to CWU, ^(68)Ga PSMA-PET/CT detected an additional 106 lesions in 33/44 patients with a positive scan, resulting in a change in management in 25/44(56.8%) patients: 10 to hormonal therapy(HT) and whole pelvis radiotherapy(RT) in addition to bed RT, and 15 to palliative HT alone.Conclusions: In the present report, we demonstrated the diagnostic and treatment decision utility of ^(68)Ga PSMA-PET/CT in Asian men with rapid BCR. Detection of small volume nodal and systemic recurrences at low PSA levels(< 1.0 ng/mL) highlights the role of the tool in assigning patients to treatment intensification with HT-RT or palliative HT in polymetastatic disease. | Janice S.H.Tan Charles X.Y.Goh Yen Sin Koh Youquan Li Jeffrey K.L.Tuan Eu Tiong Chua Terence W.K.Tan Michael L.C.Wang Lui Shiong Lee Kae Jack Tay Ravindran Kanesvaran Chee Keong Toh Aaron K.T.Tong Winnie W.C.Lam Melvin L.K.Chua | 2019 | Cancer Biology & Medicine2019，16，1： | 2 |

| 5 | Ti扩散势垒对Al/Si/Pd与n-GaAs欧姆接触热稳定性的影响显示文摘利用电子束蒸发依次将Pd,Si和Al淀积在掺杂浓度为2×10^(13)cm^(-3)的n型GaAs上,可以得到非合金、低阻的欧姆接触。比接触电阻率约为5×10^(-6)·cm^2。但经过高温(410℃),长时间热退火后,样品的表面会出现明显不平整,比接触电阻率会明显增加,在Al和Si/Pd之间加入一层Ti作为扩散势垒会使欧姆接触的热稳定性变好。但只有在Al和Ti之间的反应没有完全耗尽Ti时,扩散势垒才起作用。 | 方芳 L.C.Wang S.S.Lau | 1990 | 电子学报1990，18，5： | 0 |
| 6 | Transcriptomic analyses of localized prostate cancers of East Asian and North American men reveal race-specific luminal-basal and microenvironmental differences显示文摘Dear editor,Prostate cancer(PCa)remains a major healthcare burden in men globally[1].Most patients present with localized disease,and treatment is recommended based on risk classification systems like the National Comprehensive Cancer Network(NCCN)[2].However,these methods are imprecise for estimating metastasis-free survival and prostate cancer-specific mortality and thus biomarkers that can predict tumor aggression are needed[3–5].Several studies have since characterized the molecular landscape of localized PCa in White[4,5]and Black/African-American men[6],but data is lacking in Asian men.The Chinese Prostate Cancer Genome and Epigenome Atlas(CPGEA)reported on the genomic and epigenomic landscape of 208 PCa of men from China[7].Comparative analyses between the CPGEA cohort and data from The Cancer Genome Atlas(TCGA)revealed higher frequencies of Forkhead box A1(FOXA1)and chromodomain-helicase DNA-binding 1(CHD1)mutations,and lower frequencies of phosphatase and tensin homolog(PTEN)mutations and transmembrane protease serine 2-E26 transformationspecific related gene(TMPRSS2-ERG)fusion in Chinese compared with White men[7].These preliminary findings highlight the presence of race-specific differences in molecular phenotypes of PCa. | Melvin L.K.Chua Alexander K.Hakansson Enya H.W.Ong Boon Hao Hong Jing Jing Miao Adelene Y.L.Sim Janice S.H.Tan Kah Min Tan Gabrielle C.J.Lee Kar Perng Low Jeffrey K.L.Tuan Terence W.K.Tan Michael L.C.Wang Joe P.S.Yeong Michael C.S.Tan Lui Shiong Lee Ravindran Kanesvaran Xin Zhao Julian Ho Daniel E.Spratt Edward M.Schaeffer Kae-Jack Tay Yang Liu Elai Davicioni Li Yan Khor | 2023 | Cancer Communications2023，43，10： | 0 |
