| 1 | Unmanned aerial vehicles(UAV)for assessment of qualitative classification of Norway spruce in temperate forest stands显示文摘The study investigates the potential of UAV-based remote sensing technique for monitoring of Norway spruce health condition in the affected forest areas.The objectives are:(1)to test the applicability of UAV visible an near-infrared(VNIR)and geometrical data based on Z values of point dense cloud(PDC)raster to separate forest species and dead trees in the study area;(2)to explore the relationship between UAV VNIR data and individual spruce health indicators from field sampling;and(3)to explore the possibility of the qualitative classification of spruce health indicators.Analysis based on NDVI and PDC raster was successfully applied for separation of spruce and silver fir,and for identification of dead tree category.Separation between common beech and fir was distinguished by the object-oriented image analysis.NDVI was able to identify the presence of key indicators of spruce health,such as mechanical damage on stems and stem resin exudation linked to honey fungus infestation,while stem damage by peeling was identified at the significance margin.The results contributed to improving separation of coniferous(spruce and fir)tree species based on VNIR and PDC raster UAV data,and newly demonstrated the potential of NDVI for qualitative classification of spruce trees.The proposed methodology can be applicable for monitoring of spruce health condition in the local forest sites. | Olga Brovkina Emil Cienciala Peter Surový Přemysl Janata | 2018 | Geo-Spatial Information Science2018，21，1： | 6 |

| 20 | Minocycline fails to improve neurologic and histologic outcome after ventricular fibrillation cardiac arrest in rats显示文摘BACKGROUND Prolonged cardiac arrest(CA)produces extensive neuronal death and microglial proliferation and activation resulting in neuro-cognitive disabilities.Among other potential mechanisms,microglia have been implicated as triggers of neuronal death after hypoxic-ischemic insults.Minocycline is neuroprotective in some brain ischemia models,either by blunting the microglial response or by a direct effect on neurons.AIM To improve survival,attenuate neurologic deficits,neuroinflammation,and histological damage after ventricular fibrillation(VF)CA in rats.METHODS Adult male isoflurane-anesthetized rats were subjected to 6 min VF CA followed by 2 min resuscitation including chest compression,epinephrine,bicarbonate,and defibrillation.After return of spontaneous circulation(ROSC),rats were randomized to two groups:(1)Minocycline 90 mg/kg intraperitoneally(i.p.)at 15 min ROSC,followed by 22.5 mg/kg i.p.every 12 h for 72 h;and(2)Controls,receiving the same volume of vehicle(phosphate-buffered saline).The rats were kept normothermic during the postoperative course.Neurologic injury was assessed daily using Overall Performance Category(OPC;1=normal,5=dead)and Neurologic Deficit Score(NDS;0%=normal,100%=dead).Rats were sacrificed at 72 h.Neuronal degeneration(Fluoro-Jade C staining)and microglia proliferation(anti-Iba-1 staining)were quantified in four selectively vulnerable brain regions(hippocampus,striatum,cerebellum,cortex)by three independent reviewers masked to the group assignment.RESULTS In the minocycline group,8 out of 14 rats survived to 72 h compared to 8 out of 19 rats in the control group(P=0.46).The degree of neurologic deficit at 72 h[median,(interquartile range)]was not different between survivors in minocycline vs controls:OPC 1.5(1-2.75)vs 2(1.25-3),P=0.442;NDS 12(2-20)vs 17(7-51),P=0.328)or between all studied rats.The number of degenerating neurons(minocycline vs controls,mean±SEM:Hippocampus 58±8 vs 76±8;striatum 121±43 vs 153±32;cerebellum 20±7 vs 22±8;cortex 0±0 vs 0±0)or proliferating microglia(hippocampus 157±15 vs 193 cortex 0±0 vs 0±0;16;striatum 150±22 vs 161±23;cerebellum 20±7 vs 22±8;cortex 26±6 vs 31±7)was not different between groups in any region(all P>0.05).Numerically,there were approximately 20%less degenerating neurons and proliferating microglia in the hippocampus and striatum in the minocycline group,with a consistent pattern of histological damage across the individual regions of interest.CONCLUSION Minocycline did not improve survival and failed to confer substantial benefits on neurologic function,neuronal loss or microglial proliferation across multiple brain regions in our model of rat VF CA. | Andreas Janata Ingrid AM Magnet Kristin L Schreiber Caleb D Wilson Jason P Stezoski Keri Janesko-Feldman Patrick M Kochanek Tomas Drabek | 2019 | World Journal of Critical Care Medicine2019，8，7： | 0 |
