Treatment 2.0 Pilot in Vietnam—Early Progress and Challenges

World Journal of AIDS 2012年第2期2卷 64-70页

作者： Duc Duong Bui Fabio Mesquita Thi Nhan Do masaya kato Thi Thuy Van Nguyen Thi Minh Thu Nguyen Adrienne Poon Ministry of Health Vietnam Vietnam Authority for HIV/AIDS Control Ha Noi Vietnam World Health Organization Ha Noi Vietnam World Health Organization Ha Noi Vietnam.

Announced in 2010 at the International AIDS Conference in Vienna and pioneered by the Joint United Nations Programme on HIV/AIDS (UNAIDS) and the World Health Organization's (WHO) leadership at the global level, Treatment 2.0 is a new approach to the HIV response that encourages innovation, efficiency, and sustainability. Building upon WHO and UNAIDS' '3 by 5' Initiative, Treatment 2.0 focuses upon scale-up and universal access of life-saving ART treatment through strategic investments and innovations in five priority pillars that include: 1) Optimize drug regimens, 2) Provide point-of-care (POC) and other simplified diagnostic and monitoring tools, 3) Reduce costs, 4) Adapt service delivery, and 5) Mobilize communities [1-3]. The Treatment 2.0 approach is in line with UNAIDS' 2011-2015 Strategy: Getting to Zero with the vision of, 'Zero New infections;Zero discrimination;and Zero AIDS-related deaths', and as well as the four strategic directions for the health sector response outlined under WHO's Global Health Sector Strategy on HIV/AIDS 2011-2015 [4,5]. At the Sixty-fourth World Health Assembly (WHA) in May 2011, it was formally announced that Vietnam has taken the leadership to pilot Treatment 2.0 in two of its provinces, with support from both the WHO and UNAIDS country offices [6,7]. Given that Vietnam is one of the few countries with a concentrated epidemic to pilot Treatment 2.0, the outcomes and experiences of this initiative can provide valuable insight to other countries who may consider implementation. The objectives of this article are therefore to: 1) Describe the early process for translating Treatment 2.0 concept in Vietnam's context;and 2) Highlight early progress and challenges.

In-Situ Observation of SiC Bulk Single Crystal Growth by XRD System

引用

Journal of Rare Earths 2006年第Z1期24卷 49-53页

作者： Tomohisa kato National Institute of Advanced Industrial Science and Technology Tsukuba Central Ibaraki 305-8568 Japan

In-situ analysis for SiC bulk single crystal growth was reported using vertical X-ray diffractometer system. A furnace for SiC sublimation growth combined with the XRD system which possessed three kinds of functions including topography, rocking curve measurement and crystal growth rate monitoring was developed. These functions could contribute as a powerful tool finding the optimum growth condition by dynamic observation in the crucible. In this study, the in-situ X-ray topographs succeeded to capture dynamic elongation of defects and dislocation generated in the SiC growing crystals. The in-situ rocking curve measurement reviled appearance of mosaic structure in the SiC crystal grown with high growth rate. The in-situ growth rate monitoring also succeeded very precisely using the direct X-ray beam absorption. On the base of findings and facts obtained by the in-situ observations, the importance for the SiC growth was discussed.

GPS monitoring of temporal deformation of the Xianshuihe fault

引用

Science China Earth Sciences 2008年第9期51卷 1259-1266页

作者： TERUYUKI kato Earthquake Research Institute University of TokyoTokyo Japan

Highly precise (σ ~1 mm) temporal deformation measurements are taken across the Xianshuihe fault from two pairs of continuous GPS stations straddling the fault. Baseline vector changes of the two pairs of stations show clearly the difference in deformation behavior between the Qianning and Daofu segments of the fault: the former deforms steadily, and the latter deforms with a strong transient component. The transient deformation across the Daofu segment is possibly related to its irregular geometry, where the fault splits into two branches, that is, the east and west branches. An attempt is made to interpret the baseline vector changes using a kinematic fault model composed of a brittle layer in the upper crust, a ductile layer in the lower crust, and a transition zone in between. The slip in the transition zone of the south segment of the Xianshuihe fault is steady. The slips in the transition zones of the north and Daofu segments of the Xianshuihe fault, however, are not steady, and the average slip rates there are higher than that of the south segment. The difference in deformation behavior is probably associated with the rheological properties of the fault interface, suggesting that the overall fault strength of the south segment is greater than those of the north and Daofu segments, corresponding to longer earthquake recurrence time.

Diagnosis and therapies for gastric non-invasive neoplasia

引用

World Journal of Gastroenterology 2015年第44期21卷 12513-12518页

作者： Motohiko kato Department of Gastroenterology National Hospital Organization Tokyo Medical Center

There has been a great discrepancy of pathological diagnosis for gastric non-invasive neoplasia/dysplasia between Japanese and western pathologists. In Japan, lesions that most western pathologists diagnose as dysplasia are often considered adenocarcinoma based on nuclear and structural atypia regardless of the presence of invasion. In the Vienna classification, gastric non-invasive intraepithelial neoplasia(NIN) weredivided into low grade and high grade(including intramucosal cancer of Japanese criteria). The diagnosis by both endoscopy and pathology of biopsy specimen is difficult. Recent advances of diagnostic modality such as magnified endoscopy and imaged enhanced endoscopy is expected to improve the diagnostic yield for NIN. There are two treatment strategies for NIN, observation and diagnostic therapy by endoscopic resection(ER). ER is acceptable because of its less invasiveness and high local control rate, on the other hand, cancer-developing rate of low-grade NIN is reported to be low. Therefore there is controversy for the treatment of gastric NIN. Prospective study based on unified pathological definition is required in the future.

We shall introduce a new geometric constant A（X） of a Banach space X, which is closely related to the modulus of smoothness px （T）, and investigate it in relation with the constant As （X） by Baronti et al., the von Neumann-Jordan constant CNj（X） and the James constant J（X）. A sequence of recent results on these constants as well as some other geometric constants will be strengthened and improved.

Improvement in growth yield of single-walled carbon nanotubes with narrow chirality distribution by pulse plasma CVD

引用

Frontiers of Chemical Science and Engineering 2019年第3期13卷 485-492页

作者： Bin Xu Toshiro Kaneko Toshiaki kato Department o f Electronic Engineering Tohoku UniversitySendai 980-8579Japan Japan Science and Technology Agency (JST)-PRESTO Sendai 980-8579Japan

A pulse plasma chemical vapor deposition (CVD) technique was developed for improving the growth yield of single-walled carbon nanotubes (SWNTs) with a narrow chirality distribution. The growth yield of the SWNTs could be improved by repetitive short duration pulse plasma CVD, while maintaining the initial narrow chirality distribution. Detailed growth dynamics is discussed based on a systematic investigation by changing the pulse parameters. The growth of SWNTs with a narrow chirality distribution could be controlled by the difference in the nucleation time required using catalysts comprising relatively small or large particles as the key factor. The nucleation can be controlled by adjusting the pulse on/ofF time ratio and the total processing time.
