High-power terahertz radiation was observed to be emitted from a gas jet irradiated by 100-terawatt-class laser pulses in the laser-wakefield acceleration of *** emitted terahertz radiation was characterized in terms of its spectrum,polarization,and energy dependence on the accompanying electron bunch energy and charge under various gas target *** a nitrogen target,more than 4 mJ of energy Was produced at<10 THz with a laser-to-terahertz conversion efficiency of~0.15%.Such strong terahertz radiation is hypothesized to be produced from plasma electrons accelerated by the ponderomotive force of the laser and the plasma wakefelds on the time scale of the laser pulse duration and plasma *** model is examined with analytic calculations and particle-in-cell simulations to better understand the generation mechanism of high-energy terahertz radiation in laser-wakefield acceleration.

AIM: To expand the living donor liver transplantation(LT) pool of eligible patients with hepatocellular carcinoma(HCC) using new morphological and biological ***: Patients with HCC who underwent living donor LT(LDLT) from March 2005 to May 2013 at the National Cancer Center Korea(NCCK) were enrolled. We performed the 18F-fluorodeoxyglucose positron emission tomography/computed tomography(PET/CT)before LDLT. Overall and disease-free survival analysis was done in patients to evaluate the usefulness of new NCCK criteria using PET/CT and total tumor size(10 cm).RESULTS: We enrolled a total of 280 patients who pathologically confirmed to have HCC and performed the PET/CT before transplantation. Among them, 164(58.6%) patients fulfilled the NCCK criteria and 132 patients(47.1%) met the Milan criteria. Five-year overall and disease-free survival rates for patients who fulfilled the NCCK criteria showed 85.2% and 84.0%, respectively, and were significantly higher than those beyond the NCCK criteria(60.2% and 44.4%, respectively; P < 0.001). The correlation analysis between preoperative imaging tests and pathologic reports using Cohen's Kappa demonstrated the better results in the NCCK criteria than those in the Milan criteria(0.850 vs 0.583). The comparison of diseasefree analysis among the NCCK, Milan, and University of California, San Francisco(UCSF) criteria using the receiver operating characteristics curves revealed the similar area under the curve value criteria(NCCK vs Milan, P = 0.484; NCCK vs UCSF, P = 0.189 at 5-years).CONCLUSION: The NCCK criteria using hybrid concept of both morphological and biological parameters showed an excellent agreement between preoperative imaging and pathological results, and favorable survival outcomes. These new criteria might select the optimal patients with HCC waiting LDLT and expand the selection pool.

由于胰腺黏液性囊腺瘤具有恶变风险,所以外科手术切除经常作为治疗的首选方式。然而随着MCN临床诊治经验的积累,MCN的侵害程度低于预期。这项研究旨在通过严格的病理诊断标准再次评价来建立更令人信服的MCN的外科手术指征。方法:从1991年到2012年首尔国立大学附属医院选取94个经过手术治疗的MCN患者进行回顾性研究。病理结果经过经验丰富的病理专家再次评估。病历和影像学作为预测恶变的决定性因素。结果:94个病人中,4人被发现为胰腺导管内乳头黏液瘤。90 MCNs,60人中是低分化,21人是中分化,5人是高分化,4人为侵袭性癌症。CT上显示的小结节(P=0.005)和CA19-9是预测恶变的重要因素。所有MCN小于3 cm并且肿瘤指标正常的患者都是良性的,所有恶变患者CA19-9均大于10000U/ml。所有病人的5年生存率为98.8%,侵袭性的MCNs生存率为75.0%。结论:MCN恶变率较低。长期结果与组织学分期无关。因此,如果没有阳性体征,MCN<3 cm并且没有结节或异常肿瘤指标不作为手术指征。确认这个结论需要设计更为严谨的前瞻性研究。
