Prostate cancer metastasis-driving genes： hurdles and potential approaches in their identification

引用

Asian Journal of Andrology 2014年第4期16卷 545-548页

作者： Yan Ting Chiang Peter W Gout colin C Collins Yuzhuo Wang The Vancouver Prostate Centre Vancouver General Hospital and Department of Urologic Sciences the University of British Columbia Department of Experimental Therapeutics British Columbia Cancer Agency Vancouver British Columbia Canada.

Metastatic prostate cancer is currently incurable. Metastasis is thoughtto result from changes in the expression of specific metastasis-driving genes in nonmetastatic prostate cancer tissue, leading to a cascade of activated downstream genes that set the metastatic process in motion. Such genes could potentially serve as effective therapeutic targets for improved management of the disease. They could be identified by comparative analysis of gene expression profiles of patient-derived metastatic and nonmetastatic prostate cancer tissues to pinpoint genes showing altered expression,

Self-Cross-Linked Tannin-Aminated Tannin Surface Coatings for Particleboard

Aminated tannins were prepared by reacting mimosa condensed tannin extract with ammonia yielding the substitution of many,if not all of the tannin hydroxyl groups with–NH_(2)groups.A tannin-aminated tannin(ATT)particleboard coating was then prepared by reacting raw tannin extract with aminated tannin extract and thus cross-linking the two by substituting tannin’s hydroxyl groups with the–NH_(2)groups on the aminated tannin to form–NH-bridges between the *** resulting particleboard coating gave encouraging results when pressed at 180℃for 3 ***,the system in which tannin was reacted/cross-liked with urea(ATU)by a similar amination reaction did not perform as well as the ATT system,and this even when a higher curing temperature and longer hot press time were *** particular its water repellence was worse probably due to the presence of urea and such a system with lower ***,substituting the tannin–OHs with the urea–NH_(2)groups appeared to also take *** gave better results than ATU as regards water repellence and mechanical resistance as shown by the cross cut *** ATT system was shown to be between 95%and 98%*** difference appeared to be due,by TMA analysis,to the much faster formation of the ATT hardened network leading to a better cross-linked polymer *** chemical species formed for both the ATT and ATU system were studied by MALDI ToF and CP MAS^(13)C NMr.

HPLSE editorial tribute to Professor David Neely

High Power Laser Science and Engineering 2021年第1期9卷 69-76页

作者： colin Danson Paul McKenna High Power Laser Science and Engineering Cambridge University PressCambridgeUK AWE AldermastonReadingBerkshireUK CIFS Blackett LaboratoryImperial College LondonLondonUK Department of Physics SUPAUniversity of StrathclydeGlasgowUK

David Neely was an internationally recognised scientist who formed collaborations and friendships across the world. His passion for his work always shone through. He always made time for early-career scientists and became a mentor and supervisor to many. He was an active Editorial Board Member of the international journal High Power Laser Science and Engineering. Sadly, David was taken from us much too early. In this Editorial we pay tribute to his work through his publications in the journal.
