背景:世界卫生组织/国际防痨和肺病联合会(WHO/IUATLD)的全球抗结核病药耐药性检测规程的质量保证。目的:在WHO/IUATLD超国家参比试验室(SRL)网内部进行药敏试验熟练程度测试。设计:网内16家实验室用同样的培养物清单进行测试.每组均含有20份结核分支杆菌临床分离物,其中既有药敏培养物,也有耐药培养物,测试项目是链霉素、异烟肼、利福平和乙胺丁醇的耐药性。药敏试验包括比例法、绝对浓度法和耐药性比率法及其改良法,包括BACTEC 460放射测量法。结果:第一轮熟练程度测试表明,在SRL网内药敏试验的特异性显著高于其敏感性。异烟肼和利福平测试在各实验室之间高度一致,但链霉素和乙胺丁醇的结果不甚一致。结论:有两种抗结核病药,即异烟肼和利福平的药敏测试的各步骤在SRL网内是高度可靠的,它们可用来确定多药耐药性结核病。链霉素和乙胺丁醇的药敏试验的步骤尚有待标准化。

Cyanobacterial harmful algal blooms (CHAB), caused by eutrophication, are known to threaten both wildlife and human health. Due to urbanization and land use changes, an increase of CHAB’s at a more frequent rate within Barnegat Bay has been observed. In order to detect possible CHAB causing cyanobacteria, water samples were collected from 12 different locations within Barnegat Bay. Each sample was filtered through a 30- and 0.4-μm polycarbonate filter sequentially. Flow cytometry was carried out for the filtrate collected between 0.4- and 30-μm. Chelex DNA extraction, polymerase chain reaction (PCR), and gel electrophoresis were then performed for all sites using four primer sets (27F/785R, PSF/UR, CYA359F/CYA781R and mSF/mSR) designed to detect cyanobacteria. Flow cytometric results indicated the water samples contained a wide range of cyanobacteria, including m. aeruginosa, Cylindrospermum spp., Anabaena spp., and Synechococcus sp. IU 625 ranges from 3.16 to 8.17 × 107 cells·L-1. PCR-based assays suggest that general cyanobacteria as well as phytospecific species were present for all sites, but no toxin-producing microcystis aeruginosa was detected. Plaque assays demonstrated the presence of cyanophages for S. IU 625, Anabaena spp., and m. aeruginosa at all sites, up to 105 PFU·ml-1.

This study sought to establish the practice patterns of a diverse group of academic physicians, in the management of periprocedural anticoagulation for patients with mechanical heart valves, to study adherence to American College of Cardiology/ American Heart Association(ACC/AHA) guidelines. Physicians(n=140) were surveyed to assess strategies for the periprocedural anticoagulation of patients with bileaflet mechanical heart valves undergoing 2 common outpatient procedures. Six patient scenarios with graded risk profiles were presented for each valve location(mitral and aortic). In >90% of high-risk patient scenarios, for which the ACC/AHA guidelines recommend periprocedural anticoagulation, anticoagulation was recommended, with minimal differences between physician specialties. However, periprocedural anticoagulation was also recommended in >70% of non-high-risk scenarios, for which the ACC/AHA guidelines recommend no periprocedural anticoagulation. Noncardiologists recommended anticoagulation more often in non-high-risk patients(pmic physicians appropriately recommend periprocedural anticoagulation for high-risk patients with mechanical heart valves who undergo elective procedures. However, these data specifically suggest variability in practice for non-high-risk patients that are discordant with current ACC/AHA guidelines, with differences by treating specialty especially notable in this risk subset.

Two artificial agents(a humanoid robot and a virtual human) are enriched with various similar intelligence,autonomy, functionalities and interaction modalities. The agents are integrated in the form of a cyber-physical-social system(CPSS) through a shared communication platform to create a social ecology. In the ecology, the agents collaborate(assist each other) to perform a real-world task(search for a hidden object)for the benefits of humans. A robot-virtual human bilateral trust model is derived and a real-time trust measurement method is developed. The role of taking initiative in the collaboration is switched between the agents following a finite state machine model triggered by bilateral trust, which results in a mixedinitiative collaboration. A scheme is developed to evaluate the performance of the agents in the ecology through the *** results show that the robot and the virtual human perform satisfactorily in the collaboration through the CPSS. The results thus prove the effectiveness of the real-world ecology between artificial agents of heterogeneous realities through a shared platform based on trust-triggered mixed-initiatives. The results can help develop adaptive social ecology comprising intelligent agents of heterogeneous realities to assist humans in various tasks through collaboration between the agents in the form of a CPSS.

The surface gravity of Schwarzschild black hole can be quantized from the test particle moving around different energy states analog to the Bohr's atomic model. We have quantized the Hawking temperature and entropy of Schwarzschild black hole from quantization of surface gravity. We also have shown that the change of entropy reduces to zero when the boundary shrinks to very small size.
