那不勒斯纪实摄影师salvatore esposito拍摄和记录的主题,通常与人类文化深层次变化紧密相关。他的纪实项目长期关注于那不列斯的两类有组织犯罪:毒品犯罪和微观犯罪。salvatore历时两年半,潜入斯坎皮亚。他在那里观察、记录,切实地生活。他是外来者,也是共情者。信任是微妙的。死亡就在十英尺之外。他用黑白深邃的影像,再现斯坎皮亚之狱。

Nanotechnology plays a key role in the development of innovative scaffolds for bone tissue engineering(BTE)allowing the incorporation of nanomaterials able to improve cell proliferation and *** this study,Mg-HA-Coll type I scaffolds(Mg-HA-based scaffolds)were nanofunctionalized with gold nanorods(Au NRs),palladium nanoparticles(Pd NPs)and maghemite nanoparticles(MAG NPs).Nanofunctionalized Mg-HA-based scaffolds(NF-HA-Ss)were tested for their ability to promote both the proliferation and the differentiation of adipose-derived mesenchymal stem cells(hADSCs).Results clearly highlight that MAG nanofunctionalization substantially improves cell proliferation up to 70% compared with the control(Mg-HA-based scaffold),whereas both Au NRs and Pd NPs nanofunctionalization induce a cell growth inhibition of 94% and 89%,*** evidences were found for the osteoinductive properties showing relevant calcium deposits(25% higher than the control)for MAG nanofunctionalization,while a decreasing of cell differentiation(20% lower than the control)for both Au NRs and Pd NPs *** results are in agreement with previous studies that found cytotoxic effects for both Pd NPs and Au *** excellent improvement of both osteoconductivity and osteoinductivity of the MAG NF-HA-S could be attributed to the high intrinsic magnetic field of superparamagnetic MAG *** findings may pave the way for the development of innovative nanostructured scaffolds for BTE.

Pancreaticoduodenectomy in patients ≥ 75 years of age:Are there any differences with other age ranges in oncological and surgical outcomes? Results from a tertiary referral center

AIM To compare surgical and oncological outcomes after pancreaticoduodenectomy(PD) in patients ≥ 75 years of age with two younger cohorts of patients. METHODS The prospectively maintained Institutional database of pancreatic resection was queried for patients aged ≥ 75 years(late elderly, LE) submitted to PD for any disease from January 2010 to June 2015. We compared clinical, demographic and pathological features and survival outcomes of LE patients with 2 exact matched cohorts of younger patients [≥ 40 to 64 years of age(adults, A) and ≥ 65 to 74 years of age(young elderly, YE)] submitted to PD, according to selected variables. RESULTS The final LE population, as well as the control groups, were made of 96 subjects. Up to 71% of patients was operated on for a periampullary malignancy and pancreatic cancer(PDAC) accounted for 79% of them. Intraoperative data(estimated blood loss and duration of surgery) did not differ among the groups. The overall complication rate was 65.6%, 61.5% and 58.3% for LE, YE and A patients, respectively, P = NS). Reoperation and cardiovascular complications were significantly more frequent in LE than in YE and A groups(P = 0.003 and P = 0.019, respectively). When considering either all malignancies and PDAC only, the three groups did not differ in survival. Considering all benign diseases, the estimated mean survival was 58 and 78 mo for ≥ and < 75 years of age(YE + A groups), respectively(P = 0.012). CONCLUSION Age is not a contraindication for PD. A careful selection of LE patients allows to obtain good surgical and oncological results.
