Occurrence mechanism and coping paths of accidents of highly aggregated tourist crowds based on system dynamics

Plos.org 

by Jie Yin, Xiang-min Zheng, Ruey-Chyn Tsaur

The safety of highly aggregated tourist crowds is a challenging and important issue. This paper not only provided a comprehensive analysis of the accidents of highly aggregated tourist crowds but also determined the occurrence mechanism and coping paths. Based on the analysis of multiple cases, we found that the variable status of highly aggregated tourist crowds was the result of the interaction of three main elements: multisource pressure, state mutations and management responses.

Interleukin 10 knock-down in bovine monocyte-derived macrophages has distinct effects during infection with two divergent strains of Mycobacterium bovis

Plos.org 

by Kirsty Jensen, Joanne M. Stevens, Elizabeth J. Glass

Mycobacterium bovis is the causative agent of bovine tuberculosis (TB), a cattle disease of global importance. M. bovis infects bovine macrophages (Mø) and subverts the host cell response to generate a suitable niche for survival and replication. We investigated the role of the anti-inflammatory cytokine interleukin (IL) 10 during in vitro infection of bovine monocyte-derived Mø (bMDM) with two divergent UK strains of M. bovis, which differentially modulate expression of IL10.

Randomized control trial of Tools of the Mind: Marked benefits to kindergarten children and their teachers

Plos.org 

by Adele Diamond, Chris Lee, Peter Senften, Andrea Lam, David Abbott

The kindergarten program, Tools of the Mind (Tools), has been shown to improve executive functions (as assessed by laboratory measures) and academic performance. The objective here was to see if Tools can improve executive functions in the real world (in the classroom), academic outcomes not previously investigated, reduce bullying and peer ostracism, and increase teachers’ and students’ joy in being in the classroom.

Value of contrast-enhanced ultrasound for preoperative assessment of liver reserve function in patients with liver tumors

Plos.org 

by Huiming Yi, Baohuan Cai, Xi Ai, Ruobing Liu, Kaiyan Li, Wei Zhang

This study aimed to investigate the value of contrast-enhanced ultrasound (CEUS) for preoperative assessment of liver reserve function in patients with liver tumors. The indocyanine green (ICG) clearance tests and CEUS examinations of 45 noncirrhotic patients with liver tumors were performed prior to liver resection. Parameters time to peak (TtoPk), arrival time (Atm) as well as perfusion parameters A, k and A x k were generated from time-intensity curve (TIC) of CEUS.

Physiological stress reactivity and recovery related to behavioral traits in dogs (Canis familiaris)

Plos.org 

by Rian C. M. M. Lensen, Christel P. H. Moons, Claire Diederich

This study investigated whether stress responsiveness (in one context) can be used to predict dog behavior in daily life. On two occasions (NT1 = 32 puppies; NT2 = 16 young adults), dogs’ physiological stress response after a behavioral test at home was measured in terms of reactivity (10 min post-test) and recovery (40 min post-test) for three salivary markers: cortisol, chromogranin A (CgA) and secretory immunoglobulin A (sIgA).

Low genetic differentiation yet high phenotypic variation in the invasive populations of Spartina alterniflora in Guangxi, China

Plos.org 

by Fei-Fei Li, Lu Gong, Jun-Sheng Li, Xiao-Yan Liu, Cai-Yun Zhao

Genetic variation and population structure may reflect important information for invasion success of exotic plant species and thus help improve management of invasive plants. Spartina alterniflora is an invasive plant that is a major threat to the economy and environment of the coastal regions in China. We analyzed the genetic structure and diversity of six populations of S. alterniflora differing in invasion histories in Guangxi, China. Читать дальше...
