4Prognostic value of perioperative leukocyte count in resectable gastric cancer显示文摘AIM: To investigate the prognostic significance of perioperative leukopenia in patients with resected gastric cancer.METHODS: A total of 614 eligible gastric cancer patients who underwent curative D2 gastrectomy and adjuvant chemotherapy were enrolled in this study. The relationship between pre- and postoperative hematologic parameters and overall survival was assessed statistically, adjusted for known prognostic factors.RESULTS: The mean white blood cell count(WBC) significantly decreased after surgery, and 107/614(17.4%) patients developed p-leukopenia, which was defined as a preoperative WBC ≥ 4.0 × 109/L and postoperative WBC < 4.0 × 109/L, with an absolute decrease ≥ 0.5 × 109/L. The neutrophil count decreased significantly more than the lymphocyte count. P-leukopenia significantly correlated with poor tumor differentiation and preoperative WBC. A higher preoperative WBC and p-leukopenia were independent negative prognostic factors for survival [hazard ratio(HR) = 1.602, 95% confidence interval(CI): 1.185-2.165; P = 0.002, and HR = 1.478, 95%CI: 1.149-1.902; P = 0.002, respectively] after adjusting for histology, Borrmann type, p TNM stage, vascular or neural invasion, gastrectomy method, resection margins, chemotherapy regimens, and preoperative WBC count. The patients with both higher preoperative WBC and p- leukopenia had a worse prognosis compared to those with lower baseline WBC and no p-leukopenia(27.5 mo vs 57.3 mo, P < 0.001). CONCLUSION: Preoperative leukocytosis alone or in combination with postoperative leukopenia could be independent prognostic factors for survival in patients with resectable gastric cancer.Xiao-Feng Chen Jing Qian Dong Pei Chen Zhou Oluf Dimitri R?e Fang Zhu Shao-Hua He Ying-Ying Qian Yue Zhou Jun Xu Jin Xu Xiao Li Guo-Qiang Ping Yi-Qian Liu Ping Wang Ren-Hua Guo Yong-Qian Shu 2016World Journal of Gastroenterology2016,22,9:4
5Type 3 innate lymphoid cell-derived lymphotoxin prevents microbiota-dependent inflammation显示文摘Splenomegaly is a well-known phenomenon typically associated with inflammation.However,the underlying cause of this phenotype has not been well characterized.Furthermore,the splenomegaly phenotype seen in lymphotoxin(LT)signaling-deficient mice is characterized by increased numbers of splenocytes and splenic neutrophils.Splenomegaly,as well as the related phenotype of increased lymphocyte counts in non-lymphoid tissues,is thought to result from the absence of secondary lymphoid tissues in LT-deficient mice.We now present evidence that mice deficient in LTα1β2 or LTβR develop splenomegaly and increased numbers of lymphocytes in non-lymphoid tissues in a microbiota-dependent manner.Antibiotic administration to LTα1β2-or LTβR-deficient mice reduces splenomegaly.Furthermore,re-derived germ-free Ltbr−/−mice do not exhibit splenomegaly or increased inflammation in non-lymphoid tissues compared to specific pathogen-free Ltbr−/−mice.By using various LTβ-and LTβR-conditional knockout mice,we demonstrate that retinoic acid-related orphan receptorγT-positive type 3 innate lymphoid cells provide the required active LT signaling to prevent the development of splenomegaly.Thus,this study demonstrates the importance of LT-mediated immune responses for the prevention of splenomegaly and systemic inflammation induced by microbiota.Yuan Zhang Tae-Jin Kim Joanna A Wroblewska Vera Tesic Vaibhav Upadhyay Ralph R Weichselbaum Alexei V Tumanov Hong Tang Xiaohuan Guo Haidong Tang Yang-Xin Fu 2018Cellular & Molecular Immunology2018,15,7:3
6Successful operation of a cooperative SLR station of China and Argentina in San Juan显示文摘We introduced the observations and researches using a Satellite Laser Ranging (SLR) system with high precision, which was designed and made in China and installed in the Observatory of San Juan Uni- versity, Argentina, the capability of the system and the achievement of the cooperative procedure be- tween China and Argentina. The SLR station in San Juan, set up by China and Argentina, is quite sig- nificant for improving the distribution of SLR stations and enhancing the orbital coverage of the whole earth. Since the SLR system started to work in the Observatory of San Juan University in the beginning of 2006, the operation is rather good, and rich data with high precision have been obtained. Further plan of the cooperation for the near future is also presented.HAN YanBen LIU WeiDong E ACTIS R PODESTA WANG TanQiang GUO TangYong QU Feng A M PACHECO A A GONZALEZ E ALONSO XIANG QingGe HUANG DongPing YIN ZhiQiang 2008Chinese Science Bulletin2008,53,16:2
7Recent advances in two-photon imaging: technology developments and biomedical applications显示文摘In the past two decades, two-photon microscopy (TPM) transforms biomedicalresearch, allowing nondestructive high-resolution fluorescent molecular imaging and label-free imaging in vivo and in real time. Here we review the recent advances of TPM technologyincluding novel laser sources, new image acquisition paradiams, and microendoscopicimaging systems. Then, we survey the capabilities of TPM imagingof biological relevant molecules such as nicotinamideadenine dinucleotide (NADH), flavin adenine dinucleotide (FAD),and reactive oxygen species (ROS). Biomedical applications of TPM in neuroscience and cancer detection are demonstrated.Yu Chen Hengchang Guo Wei Gong Luye Qin Hossein Aleyasin Rajiv R Ratan Sunghee Cho Jianxin Chen Shusen Xie 2013Chinese Optics Letters2013,11,1:2

9Application of DNA barcodes in Hedyotis L.(Spermacoceae,Rubiaceae)显示文摘The potential application of DNA barcodes of plastid(matK,trnH-psbA,petD,and rbcL) and nuclear(internal transcribed spacer(ITS) of rDNA) DNA regions was investigated for 25 Hedyotis taxa.The ITS showed the best species discrimination by resolving 23 of the species as exclusive lineages with no shared alleles between any of the 24 distinct species(H.assimilis and H.mellii are not supported as distinct species based on our molecular and morphological data).Conversely,rbcL performed the worst and only resolved 10 of the species as exclusive lineages,and 10 species with shared alleles.Using ITS has the advantage of high PCR amplification success and it provides good intra-and interspecific variation distribution patterns.The most powerful plastid markers were petD and trnH-psbA,but we could amplify and sequence trnH-psbA for only 83% of the accessions sampled.Combination of ITS and petD performed extremely well,with all 24 of the distinct species resolved as exclusive lineages and no shared alleles between any of the distinct species.We therefore recommend ITS,or a combination of ITS and petD,as the standard DNA barcode in Hedyotis,but acknowledge that there are no shared alleles between distinct species for matK and rbcL combined.Xing GUO Mark R SIMMONS Paul Pui-Hay BUT Pang-Chui SHAW Rui-Jiang WANG 2011Journal of Systematics and Evolution2011,49,3:2

12Study on the Ultrastructures of Antennal Sensilla in Helicoverpa armigera显示文摘The morphology and structures of antennal sensilla of Helicoverpa armigera are observed under scanning and transmission electron microscopes. Antennae of Helicoverpa armigera are made up of scapus,pedicel and flagellum that the latter consists of 70 - 82 segments. The inner side surface of antenna is cataphracted and most of the antennal sensilla lie on its outer, upper and lower surfaces. Both the antennae of male and female contain five kinds of antennal sensilla, namely, sensillum trichodeum, sensillum basiconicum, sensillum chaeticum, ear-shaped sensillum and sensillum coeloconicum, and the kinds, number and distribution of antennal sensilla of both sexes are similar. There are a large number of serrate cuticular processes on antennal surface, especially on the middle and basic parts of antenna. Sensillum trichodeum and sensillum basiconicum, the main chemical odor receptors on antennae of Helicoverpa armigera, consist of cuticularwall, sheath cells, lymph and dendrites. There are significant differences between the internal structures of the two kinds of sensilla. In sensillum trichodeum, the cuticular-wall is thicker, less lipophilic pore channels and has one or a few dendrites, while in sensillum basiconicum, the cuticular-wall is thinner, abundant lipophilic pore channels and has much more dendrites.WANG Gui-rong, GUO Yu-yuan and WU Kong-ming( State Key Laboratory of Plant Disease and Insect Pests, The Institute of Plant Protection , Chinese Academy of Agricultural Sciences, Beijing 100094 , P.

13Deoxynivalenol accumulation and detoxification in cereals and its potential role in wheat-Fusarium graminearum interactions显示文摘Deoxynivalenol(DON)is a prominent mycotoxin showing significant accumulation in cereal plants during infection by the phytopathogen Fusarium graminearum.It is a virulence factor that is important in the spread of F.graminearum within cereal heads,and it causes serious yield losses and significant contamination of cereal grains.In recent decades,genetic and genomic studies have facilitated the characterization of the molecular pathways of DON biosynthesis in F.graminearum and the environmental factors that influence DON accumulation.In addition,diverse scab resistance traits related to the repression of DON accumulation in plants have been identified,and experimental studies of wheat–pathogen interactions have contributed to understanding detoxification mechanisms in host plants.The present review illustrates and summarizes the molecular networks of DON mycotoxin production in F.graminearum and the methods of DON detoxification in plants based on the current literature,which provides molecular targets for crop improvement programs.This review also comprehensively discusses recent advances and challenges related to genetic engineering-mediated cultivar improvements to strengthen scab resistance.Furthermore,ongoing advancements in genetic engineering will enable the application of these molecular targets to develop more scab-resistant wheat cultivars with DON detoxification traits.Kun Luo Jiao Guo Dejia He Guangwei Li Thérèse Ouellet 2023aBIOTECH2023,4,2:2
14Knockout of glutathione peroxidase 5 down-regulates the piRNAs in the caput epididymidis of aged mice显示文摘The mammalian epididymis not only plays a fun dame ntal role in the maturati on of spermatozoa,but also provides protecti on agai nst various stressors.The foremost among these is the threat posed by oxidative stress,which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids,proteins,and nucleic acids.In mice,the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5(GPX5)as a major luminal scavenger in the proximal caput epididymidal segment.Accordingly,the loss of GPX5^-/-mediated protection leads to impaired DNA integrity in the spermatozoa of aged Gpx57 mice.To explore the underlying mechanism,we have conducted transcriptomic analysis of caput epididymidal epithelial cells from aged(13 months old)Gpx5^-/-m mice.This analysis revealed the dysregulation of several thousand epididymal mRNA transcripts,in eluding the downregulation of a subgroup of piRNA pathway gen es,in aged Gpx5^-/-mice.In agreeme nt with these fin dings,we also observed the loss of piRNAs,which potentially bind to the P-element-induced wimpy testis(PlWI)-like proteins PIWIL1 and PIWIL2.The absence of these piRNAs was correlated with the elevated mRNA levels of their putative gene targets in the caput epididymidis of Gpx5^-/-mice.Importantly,the oxidative stress response genes tend to have more targeting piRNAs,and many of them were among the top increased genes upon the loss of GPX5^-/-.Taken together,our findings suggest the existence of a previously uncharacterized somatic piRNA pathway in the mammalian epididymis and its possible invoIvement in the aging and oxidative stress-mediated responses.Chen Chu Lu Yu Joelle Henry-Berger Yan-Fei Ru Ayhan Kocer Alexandre Champroux Zhi-Tong Li Miao He Sheng-Song Xie Wu-Bin Ma Min-Jie Ni Zi-Mei Ni Yun-Li Guo Zhao-Liang Fei Lan-Tao Gou Qiang Liu Samanta Sharma Yu Zhou Mo-Fang Liu Charlie Degui Chen Andrew L Eamens Brett Nixon Yu-Chuan Zhou Joel R Drevet Yong-Lian Zhang 2020Asian Journal of Andrology2020,22,6:2
