AIM to establish patient-individual tumor models of rectal cancer for analyses of novel biomarkers, individual response prediction and individual therapy *** Establishment of cell lines was conducted by direct in vitro culturing and in vivo xenografting with subsequent in vitro culturing. Cell lines were in-depth characterized concerning morphological features, invasive and migratory behavior, phenotype, molecular profile including mutational analysis, protein expression, and confirmation of origin by DNA fingerprint. Assessment of chemosensitivity towards an extensive range of current chemotherapeutic drugs and of radiosensitivity was performed including analysis of a combined radioand chemotherapeutic treatment. In addition, glucose metabolism was assessed with 18 F-fluorodeoxyglucose(FDG) and proliferation with 18 *** We describe the establishment of ultra-low passage rectal cancer cell lines of three patients suffering from rectal cancer. two cell lines(hROC126, hROC284 Met) were established directly from tumor specimens while hROC239 t0 M1 was established subsequent to xenografting of the tumor. Molecular analysis classified all three cell lines as CIMP-0/non-MSI-h(sporadic standard) type. Mutational analysis revealed following mutational profiles: hROC126: APC^(wt), tP53^(wt), KRAS^(wt), BRAF^(wt), PtEN^(wt); hROC239 t0 M1: APC^(mut), P53^(wt), KRAS^(mut), BRAF^(wt), PtEN^(mut) and hROC284 Met: APC^(wt), P53^(mut), KRAS^(mut), BRAF^(wt), PtEN^(mut). All cell lines could be characterized as epithelial(EpCAM+) tumor cells with equivalent morphologic features and comparable growth kinetics. the cell lines displayed a heterogeneous response toward chemotherapy, radiotherapy and their combined application. hROC126 showed a highly radio-resistant phenotype and hROC284 Met was more susceptible to a combined radiochemotherapy than hROC126 and hROC239 t0 M1. Analysis of 18 F-FDG uptake displayed a markedly reduced FDG uptake of all th

Bi1-xBaxFeO3 (0 ≤ x ≤ 0.3) nanopowders were synthesized using sol-gel technique. the structural and magnetic properties were investigated using X-ray diffraction, SEM and VSM. As Ba2+ doping concentration was increased, the structure of the samples changed from rhombohedral to tetragonal or monoclinic. the structural change might be an important factor for achieving the ferroelectric properties in this material. the lattice parameters were observed to increase with increase in Ba2+ concentration. All the M-h loops showed the ferromagnetic behavior. Magnetization was observed to enhance with increase in Ba concentration. the enhancement in the magnetization due to Ba2+ doping may be due to the replacement of Bi3+ ions by Ba2+ which might have resulted in the suppression of spiral spin structure.

Comparison of Respiratory Outcome between Sustained Lung Inflation and Intermittent Positive Ventilation in Preterm Infants Requiring Resuscitation at Birth

ⅩⅪ International Grassland Congress and the Ⅷ International Rangeland Congress

作者： W.D.Willms h.Douwes Agriculture and Agri-Food Canada Lethbridge AlbertaCanada T1J 4B1

＜正＞Introduction Crested wheatgrass[Agropyron cristatum（L.） Gaertn.]and Russian wildrye[Psathyrostachys juncea（Fisch.） Nevski]are commonly used for reseeding in the more xeric Mixed Prairie because they are perceived to be more productive than native ***,crested wheatgrass has been implicated in soil deterioration（Dormaar et al.,1995） while native grasses are being examined with increasing interest in Canada for their potential use in reclamation and forage production（Kerr et al.,1993）.the objectives of our study were to compare the above-ground net primary production（ANPP） and soil organic C among communities of selected native and introduced grasses and wheat,and to assess the benefits of simple mixtures.

trong>Background:trong> Sustained lung inflation (SLI) would permit lung recruitment immediately after birth, improving lung mechanics and reducing the need for intubation and subsequent respiratory support in the neonatal intensive care unit among preterm infants. Aim of the Study: To assess the efficacy of initial sustained lung inflation compared to standard intermittent positive pressure ventilation (IPPV) in preterm infants who need resuscitation in delivery room. Methods: This was prospective randomized observational study that was conducted in the delivery room and NICU of A in shames University hospital from February 2019 to September 2019. The study included 115 preterm infants between 26 - 32 weeks of gestation who needed resuscitation at delivery room. The infants were randomly allocated into 2 groups;SLI group: included the preterm infants who received the SLI at initial inflation pressure of 25 cm H2O for 15 seconds using the Neopuff/t piece. IPPV group: preterm infants who received standard resuscitation;IPPV using the self-inflating bag
