The late Aptian（118-115 Ma） continental flood basalts of the Rajmahal Volcanic Province（RVP） are part of the Kerguelen Large Igneous Province,and constitute the uppermost part of the Gondwana Supergroup on the eastern Indian shield *** lower one-third of the Rajmahal volcanic succession contains thin layers of plant fossil-rich inter-trappean sedimentary rocks with pyroclasts,bentonite,grey and black shale/mudstone and oolite,whereas the upper two-thirds consist of sub-aerial fine-grained aphyric basalts with no inter-trappean *** the eastern margin and the north-central sector of the RVP,the volcanics in the lower part include rhyolites and dacites overlain by enstatite-bearing basalts and *** pyroclastic rocks are largely felsic in composition,and comprise ignimbrite as well as coarse-grained tuff with lithic clasts,and tuff breccia with bombs,lapilli and ash that indicate explosive eruption of viscous rhyolitic *** rhyolites/dacites（〉68 wt.%） are separated from the andesites（〈 60 wt.%） by a gap in silica content indicating their formation through upper crustal anatexis with only heat supplied by the basaltic *** the other hand,partially melted siltstone xenoliths in enstatite-bearing basalts suggest that the enstatite-andesites originated through mixing of the upper crust with basaltic magma,crystallizing orthopyroxene at a pressure-temperature of ~3 kb/1150℃.In contrast,the northwestern sector of the RVP is devoid of felsic-intermediate rocks,and the volcaniclastic rocks are predominantly mafic（basaltic） in ***,the presence of fine-grained tuffs,tuff breccia containing sideromelane shards and quenched texture,welded tuff breccia,peperite,shale/mudstone and oolite substantiates a subaqueous *** on these observations,we conclude that the early phase of Rajmahal volcanism occurred under predominantly subaqueous *** presence of grey and black shale/mudstone in the lower one-third of

Necrotic feet secondary to vascular compromise in the diabetic patient may require an emergent guillotine amputation. Unrecognized, retained hardware in a distal ankle years after fracture repair may complicate the intraoperative guillotine amputation at the transtibial/fibula level. Troubleshooting such an unexpected surgical problem is not necessarily straightforward depending on the clinical situation. Presented is a case report where a patient with a necrotic burned foot failed to inform the burn team that he had implanted ankle hardware, prior to his surgical intervention. A successful amputation was completed after proceeding down a specific algorithm devised for such a scenario.

大约30年前,表皮生长因子受体（epithelial growth factor receptor,EGFR）被认为是癌症治疗较为合适的靶点[1-2]。随后,肿瘤学家尝试去观察部分恶性肿瘤细胞的增殖是否依赖于EGFR的激活以及相应细胞内酪氨酸激酶下游信号的传递。

AIM To investigate infused hematopoietic cell doses and their interaction with conditioning regimen intensity +/-total body irradiation(TBI) on outcomes after peripheral blood hematopoietic cell transplant(PBHcT).METHODS Our retrospective cohort included 247 patients receiving a first, T-replete, human leukocyte antigen-matched allogeneic PBHcT and treated between 2001 and2012. correlations were calculated using the Pearson product-moment correlation coefficient. Overall survival and progression free survival curves were generated using the Kaplan-Meier method and compared using the log-rank *** Neutrophil engraftment was significantly faster after reduced intensity TBI based conditioning [reduced intensity conditioning(RIc) + TBI] and > 4 × 10~6 cD34+cells/kg infused. A higher total nucleated cell dose led to a higher incidence of grade II-IV acute graft-versus-host disease in the myeloablative + TBI regimen group(P = 0.03), but no significant difference in grade III-IV graft-versus-host disease. A higher total nucleated cell dose was also associated with increased incidence of moderate/severe chronic graft-versus-host disease, regardless ofconditioning regimen. Overall and progression-free survival were significantly better in patients with a RIc + TBI regimen and total nucleated cell dose > 8 ×10~8/kg(3 years, overall survival: 70% vs 38%, P = 0.02, 3 years, progression free survival: 64% vs 38%, P = 0.02).cONcLUSION TBI and conditioning intensity may alter the relationship between infused cell doses and outcomes after PBHcT. Immune cell subsets may predict improved survival after unmanipulated PBHcT.

水产养殖对生物多样性很少有有正面影响,有时没有影响,但通常有某种程度的负面影响。影响包括:资源消耗,例如,土地(或空间)、水、种苗和饲料等的消耗;水产品深加工;废物的产生(未吃掉的食物、粪尿、化学药品、微生物、寄生物和野生养殖的有机体)。负面影响可以是直接的,如外来遗传材料的引入;或是间接的,如栖息地和小生境的丧失。结论是,在决定水产养殖这种食物生产方法是否可接受时,关键问题在于资源利用的规模、强度,以及废物的净生产。本文还认为,从水产养殖者的观点出发,有必要对生物多样性进行保护。

Phase relations in the Mo Si c, Mo Si Al and Mo Si Ti B systems were investigated via sample production, heat treatment and characterization, using light optical microscopy(LOM), scanning electron microscopy(SEM), electron probe microanalysis(EPMA), X ray diffraction(XRD), image analysis, light element analysis, Vickers hardness and fracture toughness measurements. The results led to many signigicant conclusions.
