Previously, we showed that prophylactic addition of glucose to Harsha Lake water samples could inhibit cyanobacteria growth, at least for a short period of time. The current study tested cyanobacterial control with glucose for the entire Harsha Lake bloom season. Water samples (1000 ml) were collected weekly from Harsha Lake during the algal-bloom season starting June 9 and lasting until August 24, 2022. To each of two 7-liter polypropylene containers, 500 ml of Harsha Lake water was added, and the containers were placed in a controlled environment chamber. To one container labeled “Treated,” 0.15 g of glucose was added, and nothing was added to the container labeled “Control.” After that, three 25 ml samples from each container were collected and used for 16S rRNA gene sequencing each week. Then 1000 ml of Harsha Lake water was newly collected each week, with 500 ml added to each container, along with the addition of 0.15 g glucose to the “Treated” container. Sequencing data were used to examine differences in the composition of bacterial communities between Treated and Control containers. Treatment with glucose altered the microbial communities by 1) reducing taxonomic diversity, 2) largely eliminating cyanobacterial taxa, and 3) increasing the relative abundance of subsets of non-cyanobacterial taxa (such as Proteobacteria and Actinobacteriota). These effects were observed across time despite weekly inputs derived directly from Lake water. The addition of glucose to a container receiving weekly additions of Lake water suppressed the cyanobacterial populations during the entire summer bloom season. The glucose appears to stimulate the diversity of certain bacterial taxa at the expense of the cyanobacteria.

Non-obstacle design is critical to tailor physically handicapped workers in manufacturing system. Simultaneous consideration of variability in physically disabled users, machines and environment of the manufacturing system is extremely complex and generally requires modeling of physically handicapped interaction with the system. Most current modeling either concentrates on the task results or functional disability. The integration of physical constraints with task constraints is far more complex because of functional disability and its extended influence on adjacent body parts. A framework is proposed to integrate the two constraints and thus model the specific behavior of the physical handicapped in virtual environment generated by product specifications. Within the framework a simplified model of physical disabled body is constructed, and body motion is generated based on 3 levels of constraints（effecter constraints, kinematics constraints and physical constraints）. The kinematics and dynamic calculations are made and optimized based on the weighting manipulated by the kinematics constraints and dynamic constraints. With object transferring task as example, the model is validated in Jack 6.0. Modelled task motion elements except for squatting and overreaching well matched with captured motion elements. The proposed modeling method can model the complex behavior of the physically handicapped by integrating both task and physical disability constraints.

目的探讨儿童过敏性紫癜(HSP)的口腔菌群及其代谢产物特征,阐明过敏性紫癜发病的机制。方法纳入合格受试者3组,其中HSP组20例,紫癜性肾炎(HSPN)组20例,对照组20例。对各组的唾液进行16S rRNA测序和代谢组学分析,分析差异性菌群与差异性代谢物之间的相关性。结果(1)与对照组相比,HSPN组丰富度和多样性差异有统计学意义(P0.05)。与HSP组相比,HSPN组丰富度和多样性显著升高(P<0.05)。其中属水平上,各组中链球菌占比最高。与对照组相比,HSP组无显著性相关菌属,HSPN组假单胞菌属和副拟杆菌属显著增高(P<0.05)。与HSP组相比,HSPN组假单胞菌属和副拟杆菌属相对丰度显著升高(P<0.05)。(2)与对照组相比,HSPN组有12种差异性代谢产物,涉及苯丙氨酸代谢等9种代谢途径;HSP组差异无统计学意义代谢产物,无代谢通路。与HSP组相比,HSPN组有15种差异性代谢产物,涉及苯丙氨酸代谢等9种代谢途径。(3)HSPN组与对照组中假单胞菌属、副拟杆菌属与苯丙氨酸代谢途径产物呈负相关。HSPN组与HSP组中假单胞菌属、副拟杆菌属与苯丙氨酸代谢途径产物呈负相关。口腔中参与苯丙氨酸代谢的代谢产物为2-羟基肉桂酸、苯丙酮酸、N-乙酰基-L-苯丙氨酸。结论链球菌属、假单胞菌属、副拟杆菌属可能作为HSPN发病的触发因素之一,苯丙氨酸代谢可能是HSPN的发病过程中的通路之一。相比于HSP患儿,HSPN患儿口腔菌群失调更加明显,代谢产物差异性更强。
