Osteomyelitis is a.deva.ta.ing disea.e ca.sed by microbia. infection of bone. While the frequency of infection following elective orthopedic surgery is low, ra.es of reinfection a.e disturbingly high. Sta.hylococcus a.reus is responsible for the ma.ority of chronic osteomyelitis ca.es a.d is often considered to be incura.le due to ba.teria. persistence deep within bone. Unfortuna.ely, there is no consensus on clinica. cla.sifica.ions of osteomyelitis a.d the ensuing trea.ment a.gorithm. Given the high pa.ient morbidity,morta.ity, a.d economic burden ca.sed by osteomyelitis, it is importa.t to elucida.e mecha.isms of bone infection to inform novel stra.egies for prevention a.d cura.ive trea.ment. Recent discoveries in this field ha.e identified three distinct reservoirs of ba.teria. biofilm including: Sta.hylococca. a.scess communities in the loca. soft tissue a.d bone ma.row, glycoca.yx forma.ion on impla.t ha.dwa.e a.d necrotic tissue, a.d coloniza.ion of the osteocyte-la.uno ca.a.icula. network(OLCN) of cortica. bone. In contra.t, *** intra.ellula. persistence in bone cells ha. not been substa.tia.ed in vivo, which cha.lenges this mode of chronic osteomyelitis. There ha.e a.so been ma.or a.va.ces in our understa.ding of the immune proteome a.a.nst S. a.reus, from clinica. studies of serum a.tibodies a.d media.enriched for newly synthesized a.tibodies(MENSa., which ma. provide new opportunities for osteomyelitis dia.nosis, prognosis, a.d va.cine development. Fina.ly, novel thera.ies such a. a.timicrobia. impla.t coa.ings a.d a.tibiotic impregna.ed 3D-printed sca.folds represent promising stra.egies for preventing a.d ma.a.ing this deva.ta.ing disea.e.

过去几十年的博物馆研究和博物馆专业人员实践探索了博物馆传播的关键原则。博物馆展览建设有策划、设计、施工三个阶段。阐释策划阶段要弄清楚为什么要做这个项目,目标观众是谁,主题是什么,展览的背景情况是什么。阐释设计阶段就要了解展览内容,进行分众传播,具有可达性和真实性,而最核心原则是激发、关联和揭示。施工是实现一个高质量博物馆展览的最后阶段。这些阐释策划、阐释设计、内容创意和展览实施中的规范和标准是博物馆创建世界级展览最有效的方法,也是和观众沟通的有效手段。

背景:前人研究已报道有关健全和残障儿童基础动作技能和体力活动间存在正相关,本研究尝试探讨这种关系的因果机制。我们假设当基础动作技能熟练度改善时,健全和残障儿童对体力活动的领悟力均会提高其:改善基础动作技能熟练度对残障儿童影响更大。方法:受试者包括典型发育的健全和有脑性麻痹的儿童,分别分配在基础动作技能训练组和对照组。训练组练习5组基础动作技能(跑、跳、踢、扔、抓),每周45 min,练习4周。对照组进行常规的物理治疗或体育活动课程。基础动作技能以过程和产品为导向的措施进行评估,用加速器测量训练前后的体力活动。结果:训练组的基础动作技能提高而对照组未提高。工作日体力活动都没有显著改变。常规物理治疗基础动作技能训练在周末增加了中高强度体力活动,然而常规物理治疗基础动作技能训练组和活动基础动作技能组在周末久坐时间都有减少。参加中高强度体力活动及久坐时变化程度大于可测量最小值(MDC_(90))受试者的百分比在脑瘫患儿中高于健全儿童。结论:周末提高基础动作技能熟练度可能会促进儿童增加体力活动、减少久坐时间。通过提高基础动作技能熟练度增强体力活动对残疾儿童的影响大于健全儿童。本研究的发现应在未来研究中得到进一步检测。
