Forest management planning often relies on Airborne Laser Scanning(ALS)-based Forest Management Inventories(FMIs)for sustainable and efficient *** the area-based(ABA)approach,these inventories estimate forest characteristics for grid cell areas(pixels),which are then usually summarized at the stand *** the ALS-based high-resolution norwegian Forest Resource Maps(16 m×16 m pixel resolution)alongside with stand-level growth and yield models,this study explores the impact of three levels of pixel aggregation(standlevel,stand-level with species strata,and pixel-level)on projected stand *** results indicate significant differences in the projected outputs based on the aggregation ***,the most substantial difference in estimated volume occurred between stand-level and pixel-level aggregation,ranging from-301 to+253 m^(3)·ha^(-1)for single *** differences were,on average,higher for broadleaves than for spruce and pine dominated stands,and for mixed stands and stands with higher variability than for pure and homogenous *** conclusion,this research underscores the critical role of input data resolution in forest planning and management,emphasizing the need for improved data collection practices to ensure sustainable forest management.

We developed a serum-free culture system that promoted the growth of B cell colonies in peripheral blood, bone marrow, lymph nodes and cerebrospinal fluid (CSF) from 7 out of 8 patients with non-Hodgkin's lymphomas of B cell type. The culture cells were pretreated with or without galactose oxi-dase (GO) prior to plating. Colony growth was best supported with BCGF. A moderate increment was observed with rIL-3, as well as rIL-1β and even to a lesser degree, by rlL-2, while B cell stimulating factor-2 (rBCSF-2) and rlL-1β did not show significant activity. rGM-CSF and rG-CSF had little effect, while rM-CSF enhanced the formation of lymphoma colonies. The cells from different patients had different requirements for Staphylococcus aureus protein A and GO pretreatment. It reflected the differences in activation and differentiation status and surface properties of lymphoma cells from different patients. The cells from CSF of one patient were successfully maintained in serum-free culture medium supplemented with 10% BCGF or 5% Pha-LCM for more than 4 months. The long-term culture cells were EBV negative, phenotypically consistent with B cells and gene rearrangements for JH, Kappa and myc. This serum-free culture system allowed extensive analysis of the growth requirements for clonogenic precursors.

目的验证黄芪对脓毒症急性呼吸窘迫综合征小鼠的治疗效果并探究其作用机制。方法70只SPF级C57小鼠,按照随机数字表法分为黄芪组(n=30)、对照组(n=30)、假手术组(n=10),对其中黄芪组、对照组小鼠行CLP手术以诱发脓毒症急性呼吸窘迫综合征,假手术组行CLP假手术;术后黄芪组以黄芪水煎剂灌胃治疗,假手术组、对照组以生理盐水灌胃,术后12 h、24 h将小鼠处死取材,取观察肺组织病理,测定肺组织干湿重比、肺泡灌洗液蛋白浓度,对肺泡灌洗液和血清进行蛋白质组学分析,对差异蛋白进行富集分析。结果黄芪减轻了ARDS模型小鼠的BALF总蛋白浓度,降低了ARDS模型小鼠的肺干湿重比,对肺组织的HE染色表明,黄芪水煎剂改善了ARDS小鼠的急性肺泡损伤。对血清样本和BALF样本的蛋白质组学分析显示黄芪组与对照组存在一定的差异蛋白,对其进行富集分析显示主要富集在炎症因子的通路上,证实黄芪水煎剂可能是通过抑制炎症因子的激活和释放发挥作用机制的。结论黄芪水煎剂有效减轻了脓毒症急性呼吸窘迫综合征的肺组织炎症渗出,其作用机制可能为抑制炎症因子的蛋白表达。

We analytically and numerically compute the Onsager dissociation rate(exciton dissociation)on an interface induced by a piezoelectric potential in an inorganicorganic hybrid p-n junction system(ZnO+(poly(p-phenylene vinylene));PPV).When a positive piezoelectric potential is created at the interface region owing to the deformation of the system,free electrons accumulate at the ***,screening effects are *** is assumed that the electron layer formed at the interface then attracts free holes from the p-type PPV region,which leads to exciton formation,possibly via the Langevin recombination *** increased exciton density can then contribute to the Onsager dissociation rate,which is maximum around the *** paper focuses on the role of piezoelectric effects in promoting exciton formation at the interface and its relation with the exciton dissociation rate.
