Background:Gross motor skills are postulated to have a bidirectional relationship with physical activity(PA);however,no study has tested this relationship bef.re and af.er a summer *** purpose of.this study was to examine the bidirectional relationships between school PA and gross motor skills in children bef.re and af.er a summer ***:Participants were a sample of.440 children recruited f.om 3 low-income schools(age=8.9±1.2 years,mean±SD).PA was assessed as average school-day step counts using Yamax DigiWalker pedometers(Yamasa Tokei Keiki,Tokyo,Japan)worn f.r 5 consecutive school *** motor skills were assessed using the Test f.r Gross Motor Development,3 rd *** were collected at 2 timepoints:at the end of.spring semester(T1)and at the beginning of.the subsequent f.ll semester(T2).An age-and body mass index-adjusted cross-lagged model was employed to relate T1 school step counts with T2 gross motor skills and T1 gross motor skills with T2 school step ***:T1 gross motor skills signif.cantly predicted T2 school step counts(β=0.24,95%conf.dence interval(95%CI):0.08-0.40,p=0.003);however,Tl school step counts did not predict T2 gross motor skills(β=0.04,95%CI:-0.06 to 0.14,p=0.445).The model explained 35.4%and 15.9%of.the variances of.T2 gross motor skills and T2 school step counts,*** analyses indicated that these relationships were driven primarily by ball ***:The relationship between gross motor skills and school PA was not bidirectional;however,higher gross motor skills,specif.cally ball skills,predicted higher school PA af.er a 3-month summer break.

Osteomyelitis is a devastating disease caused by microbial inf.ction of.bone. While the f.equency of.inf.ction f.llowing elective orthopedic surgery is low, rates of.reinf.ction are disturbingly high. Staphylococcus aureus is responsible f.r the majority of.chronic osteomyelitis cases and is of.en considered to be incurable due to bacterial persistence deep within bone. Unf.rtunately, there is no consensus on clinical classif.cations of.osteomyelitis and the ensuing treatment algorithm. Given the high patient morbidity,mortality, and economic burden caused by osteomyelitis, it is important to elucidate mechanisms of.bone inf.ction to inf.rm novel strategies f.r prevention and curative treatment. recent discoveries in this f.eld have identif.ed three distinct reservoirs of.bacterial biof.lm including: Staphylococcal abscess communities in the local sof. tissue and bone marrow, glycocalyx f.rmation on implant hardware and necrotic tissue, and colonization of.the osteocyte-lacuno canalicular network(OLCN) of.cortical bone. In contrast, *** intracellular persistence in bone cells has not been substantiated in vivo, which challenges this mode of.chronic osteomyelitis. There have also been major advances in our understanding of.the immune proteome against S. aureus, f.om clinical studies of.serum antibodies and media enriched f.r newly synthesized antibodies(MENSA), which may provide new opportunities f.r osteomyelitis diagnosis, prognosis, and vaccine development. f.nally, novel therapies such as antimicrobial implant coatings and antibiotic impregnated 3D-printed scaf.olds represent promising strategies f.r preventing and managing this devastating disease. Here, we review these recent advances and highlight translational opportunities towards a cure.

1 前言板块的相对运动方向与海沟轴走向斜交的会聚板块边界是沿太平洋盆地边缘的主要板块边界类型。板块运动的斜交角变化较大。一种极端是,大洋边缘的区域走向近乎与会聚方向垂直(例如,马里亚纳、汤加和东阿留申)。另一个极端是,斜交角很大,以致沿边缘很少有弧火山作用。绝大部分板内应力是由长而深的贯穿性转换断层的剪切作用引起的。本文阐述的重点是这种边缘,即那里的斜会聚的水平分量至少部分地在横向上分段成连续的走滑断层系,其主要位移方向平行或亚平行于边界。Jarrard(1986a)估计,百分之五十以上的活动俯冲带伴随着平行于板块边界的走滑断层。
