Orlando , fla . - - in the largest single - institution retrospectie study to date , researchers at mayo clinic cancer center hae shown that giing patients both radiation and chemotherapy after completely remoing inasie pancreatic cancer may improe oerall surial rates 来自弗罗里达州奥兰多市的报道- - -在迄今为止大量的单一机构回顾性研究中，梅奥诊所癌症中心的研究人员发现在完全切除侵袭性胰腺癌后给予患者放射和化学治疗可以提高总生存率。
Intra - operative monitoring of cortically recorded somatosensory evoked potentials ( seps ) by peripheral nerve stimulation is of value during orthopaedic surgery and is the state - of - the - art in terms of non - invasiveness , versatility , time requirement , lateral discrimination , and ease of electrode placement 通过外周神经刺激由皮质记录的体感诱发电位的术中监测在骨科手术中具有重要价值，具有非侵袭性，多功能，需时，侧方识别，容易电极插入等优点。
The theory and experiment of measuring diffusion coefficients in terms of mr signal attenuation has been established for decades , but recent advance of diffusion tractography has enabled us , for the first time , to visualize and analyze the axonal fiber tracts in the living brain non - invasively 其实，利用磁振讯号衰减量测到扩散系数之理论与实验已确立了几十年，但近年来扩散神经纤维束造影的发展，第一次使我们能够在活体非侵袭性的观察和分析神经轴突纤维束。
Salmonella typhimuriwn , one of the invasive bacterial species , can be attenuated without loss of invasiveness and thus used for delivery of eukaryotic expression vectors into host cells in vivo . the recombinant plasmid containing the target gene is released inside the host cells and gain entry into the nucleus , resulting in expression of encoded antigens and subsequent induction of humoral and cellular immune responses 沙门氏菌( salmonellatyphimurium )是一种较为常见的侵袭性胞内菌，通过基因工程方法减毒后对宿主致病性显著降低，但仍保留良好的侵袭力，可直接将真核表达质粒携带进入动物细胞内表达相应的蛋白而诱导特异性的免疫应答反应。
To dress the question if other virulence gene were present in this kind of strains , 152 of 436 irp2 - hybridized strains were re - confirmed and selected for this study . the virulence genes or putative virulence genes detected by pcr or hybridization include heat stable toxin ( st ) & heat labile toxin ( lt ) for enterotoxigenic e . coli ( etec ) , invasive plasmid antigen b ( ipab ) for enteroinvasive e . coli ( eiec ) , epec adherence factor ( eaf ) , epec secretion protein c ( espc ) for enteropathogenic e . coli ( epec ) , hemolysin ( hlya ) and shiga toxins ( sltl and slt2 ) for enterohaemorrhagic e . coli ( ehec ) and eaggec probe for entero - aggregative e . coli ( eaggec ) . the prra and yc73 genes of pathogenicity associated island ( pai ) of urepathogenic e . coli ( upec ) and " o " island 28 ( rtx 615 ) gene was also detected , the later was a newly discovered putative pathogenicity island in e . coli o157 : h7 为探讨携带小肠结肠炎耶尔森氏菌的hpi毒力岛的大肠杆菌是否具有其他已知的毒力基因，选取82株由原位杂交和pcr方法初筛irp2阳性的大肠杆菌菌株，进行在致泻性大肠杆菌的25个毒力基因的检测，包括肠产毒性大肠杆菌的热稳定毒素st和热不稳定毒素lt ，肠侵袭性大肠杆菌的侵袭蛋白b基因ipab ，肠致病性大肠杆菌的eaf 、 espc基因，肠出血性大肠杆菌的溶血素hly 、志贺毒素1 ( slt1 ) 、志贺毒素2 ( slt2 )基因，肠集聚性大肠杆菌的eaggec探针，以及在泌尿道致病性大肠杆菌和o157 ： h7大肠杆菌中新发现的毒力岛基因。
It has been suggested that patients with hepatocellular carcinoma ( hcc ) undergoing living donor liver transplantation ( ldlt ) have worse recurrence - free survival compared to deceased donor liver transplantation ( clt ) , leading to the hypothesis that short waitlist time or fast - tracking may include more aggressive tumors that would have been selected out by traditionally longer waitlist time 因有已经提议认为肝细胞癌的患者，接受活体供体肝移植的相对于尸体供体肝移植而言，有更坏的存活期无复发率（即更快的移植后复发率） ，导致了认为可能包括更有侵袭性的肿瘤的患者应该在传统的长时间等待名单上被挑选出来，以短暂等待时间或者快速示踪（的方式尽快接受肝移植的）假说。
