| 1 | Carbon isotopic characteristics and their genetic relationships for individual lipids in plants and sediments from a marsh sedimentary environment显示文摘The carbon isotopes of individual lipids in herbaceous plants and tree leaves in Ruoergai marsh were measured by the GC-IRMS analytical technique in order to understand the inherent relationships of carbon isotopes between sedimentary and plant lipids from typical marsh environment. The analytical results show that the carbon isotopic compositions of n-alkanes in different kinds of plants differ significantly. Mean δ 13C values of n-alkanes in her-baceous plants (?32.2‰―?36.9‰) are 3.3‰ lower than those in woody plant (?27.2‰― ?35.0‰). The carbon isotopic compositions of fatty acids in organisms (?30.3‰― ?36.2‰) are very similar to those of n-alkanes and the δ 13C values for unsaturated fatty acids are within the range of those for saturated fatty acids. The differences in δ 13C values between plant lipids are obvious and range from 2.4‰ to 7.8‰. It is observed that the carbon isotopic compositions of sedimentary lipids are closely related to those of plant lipids. The carbon isotopic compositions (?27.0‰―?36.9‰) of n-alkanes, ≥C16 fatty acids, n-alkanols, sterols and n-alkanones in the sediments are similar to those of plant lipids and the carbon isotopic compositions of short-chain sedimentary lipids are similar to those of long-chain sedimentary homologues. These indicate that the sedimentary lipids are derived from high plants. However, the δ 13C values of C14:0 and C15:0 fatty acids in the sediments are lighter than those of the same carbon number saturated homologues in plants, reflecting the genetic features partially derived from bacteria. These data provide scientific evidence for carbon isotope-applied research of individual lipids. | DUAN Yi1, ZHANG Hui1, ZHENG Chaoyang1, WU Baoxiang1 & ZHENG Guodong2 1.

Based on a calculation of diffraction pattern. the orientation relations between precipitates and matrix are given in detail. The influence of solution temperature on growth of γ' precipitates was investigated. and a γ' precipitate free area near δ phase was found. The coarsening behaviour of γ' precipitates during short time aging is | Jianhong HE (Dept. of Mater. Sci. and Eng., Tsinghua University, Beijing, 100084, China)S.Fukuyama and K.

| 4 | Patient-derived orthotopic xenograft models for cancer of unknown primary precisely distinguish chemotherapy,and tumor-targeting S.typhimurium A1-R is superior to first-line chemotherapy显示文摘Cancer of unknown primary(CUP)is a recalcitrant disease with poor prognosis because it lacks standard first-line therapy.CUP consists of diverse malignancy groups,making personalized precision therapy essential.The present study aimed to identify an effective therapy for a CUP patient using a patient-derived orthotopic xenograft(PDOX)model.This paper reports the usefulness of the PDOX model to precisely identify effective and ineffective chemotherapy and to compare the efficacy of S.typhimurium A1-R with first-line chemotherapy using the CUP PDOX model.The present study is the first to use a CUP PDOX model,which was able to precisely distinguish the chemotherapeutic course.We found that a carboplatinum(CAR)-based regimen was effective for this CUP patient.We also demonstrated that S.typhimurium A1-R was more effective against the CUP tumor than first-line chemotherapy.Our results indicate that S.typhimurium A1-R has clinical potential for CUP,a resistant disease that requires effective therapy. | Kentaro Miyake Tasuku Kiyuna Masuyo Miyake Kei Kawaguchi Sang Nam Yoon Zhiying Zhang Kentaro Igarashi Sahar Razmjooei Sintawat Wangsiricharoen Takashi Murakami Yunfeng Li Scott D.Nelson Tara A.Russell Arun S.Singh Yukihiko Hiroshima Masashi Momiyama Ryusei Matsuyama Takashi Chishima Shree Ram Singh Itaru Endo Fritz C.Eilber Robert M.Hoffman | 2018 | Signal Transduction and Targeted Therapy2018，3，1： | 2 |
