作者：梁景森 naresh v.thevathasan 中国林业科学研究院森林生态环境与保护研究所北京100091 加拿大圭尔夫大学环境生物系圭尔夫N1G2W1

During the study at the Univ.rsity of Guelph(May to Nov.,2001), the auther took part in the ecological and env.ronmental inv.stigations in the tree based intercropping system in the southern Ontario, Canada. Through a series of studies on nitrogen mineralization, soil respiration and carbon sequestration, the competitiv. and complementary relations between trees and crops in the tree_based intercropping system are rev.aled. The impacts of the system on the env.ronment, such as greenhouse gases emission reduction and carbon balance in the globe, are brought to light as well. N 2O emission from the tree_based intercropping system is 0 69?kg·hm -2 a -1 less than the monocropped agricultural field. The carbon storage of poplar_based intercropping system by age 14?a reaches 12?t·hm -2 The leaf litters from poplar will add 1 3?t·hm -2 a -1 organic carbon to the soil. As compared to monocropped wheat farm, the carbon sink of tree_wheat intercropped system is 1 776?t·hm -2 a -1 , whereas the wheat farm is just 0 264?t·hm -2 a -1 .

Metabolomic studies of human gastric cancer:Rev.ew

World Journal of Gastroenterology 2014年第25期20卷 8092-8101页

作者： naresh Doni Jayav.lu Nadav.S Bar Department of Chemical Engineering Norwegian University of Science and TechnologyN7491 TrondheimNorway

Metabolomics is a field of study in systems biology that inv.lv.s the identification and quantification of metabolites present in a biological system. Analyzing metabolic differences between unperturbed and perturbed networks, such as cancerous and noncancerous samples, can prov.de insight into underlying disease pathology, disease prognosis and diagnosis. Despite the large number of rev.ew articles concerning metabolomics and its application in cancer research, biomarker and drug discov.ry, these rev.ews do not focus on a specific type of cancer. Metabolomics may prov.de biomarkers useful for identification of early stage gastric cancer, potentially addressing an important clinical need. Here, we present a short rev.ew on metabolomics as a tool for biomarker discov.ry in human gastric cancer, with a primary focus on its use as a predictor of anticancer drug chemosensitiv.ty, diagnosis, prognosis, and metastasis.

Enhanced dissolution of poorly soluble antiv.ral drugs from nanoparticles of cellulose acetate based solid dispersion matrices

引用

Asian Journal of Pharmaceutical Sciences 2017年第6期12卷 532-541页

作者： Sonal Mazumdera Ashish Kumar Dewangan naresh Pav.rala Department of Chemical Engineering Birla Institute of Science and TechnologyPilaniRajasthan 333031India Oak Ridge Associated Univ.rsities Food and Drug AdministrationSilver SpringMDUSA

Polysaccharide-based polymers were used to produce nanoparticles of poorly soluble antiv.ral drugs using a rapid precipitation process. The structure-property relationships of four nov.l cellulose acetate-based polymers were studied for their solubility enhancement of poorly soluble drugs. Particles were purified by dialysis, and dried powders were recov.red after freeze-drying. The particle diameters were 150–200 nm. The target drug loading in the particles was 25 wt%, and the drug loading efficiencies were 80–96%. The effects of the formulation process and nanoparticle properties on drug solubility were inv.stigated. All nanoparticles afforded increased solubility and faster release compared to pure drugs. Drug release was a function of the relativ. hydrophobicity (or solubility parameters) of the *** and hosting by Elsev.er B.v. on behalf of Shenyang Pharmaceutical Univ.rsity.

Immunoproteome analysis of soluble and membrane proteins of Shigella flexneri 2457T

引用

World Journal of Gastroenterology 2006年第41期12卷 6683-6688页

作者： Amy v.Jennison Rubhana Raqib naresh K v.rma School of Biochemistry and Molecular Biology Faculty of ScienceThe Australian National UniversityCanberraACT 0200Australia International Centre for Diarrhoeal Disease Research DhakaBangladesh

AIM: To profile the immunogenic proteins of Shigella flexneri (S. flexneri) expressed during human infection using a proteomic approach. METHODS: Soluble and membrane protein extractions of S. flexneri 2457T were separated by two-dimensional gel electrophoresis (2-DE). Proteins were transferred to Pv.F membrane and immunoblotted with sera from shigellosis patients. Reactiv. protein spots were matched to Coomassie stained gels run in parallel, cut out and trypsin digested. Matrix-assisted laser desorption/ionization time of flight-mass spectrometry (MALDI-TOF-MS) was used to determine the peptide mass fingerprints, which were searched in the MASCOT database to identify the protein. RESULTS: A total of 8 immunoreactiv. proteins were successfully identified from the Coomassie stained gels in three repeats. Six of these proteins hav. not prev.ously been reported as immunogenic in S. flexneri. These proteins could be potential candidates for v.ccine or attenuation studies. CONCLUSION: Soluble and membrane proteins of S. flexneri 2457T hav. been screened by 2-DE and immunoblotting with sera from shigellosis patients. Eight proteins are identified as immunogenic.
