A new rapid home test for faecal calprotectin in ulcerative colitis

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 2 2010
M. ELKJAER
Summary Background, Enzyme-linked immunosorbent assay (ELISA) is a time-consuming method for the measurement of faecal calprotectin. Two new quantitative rapid tests have been developed. Aim, To compare the new rapid tests with ELISA as ,Gold Standard'. Methods, Quantitative analysis involved the application of a sample onto the ,Lateral Flow Device'. The colour intensity of a test line was read using a laptop computer linked to a scanner (rapid test scanning). A picture taken with a mobile phone (HT photo) of the same ,Lateral Flow Device' was sent to a server via Mobile Internet and the result appeared on the phone screen after 15 s. Results, A total of 404 faecal samples were analysed. Mean differences of 1.7 mg/kg (range ,23.4,20.1) ELISA vs. rapid test scanning, 6.8 mg/kg (,28,14.5) ELISA vs. HT photo and 2.9 mg/kg (,10.3,4.5) rapid test scanning vs. HT photo were found with good agreement calculated using kappa statistic (86%, 87% and 95% respectively). The Coefficients of Variation for HT photo was <10%, with a sensitivity of 96.2% and a specificity of 90.1%. Conclusions, The new rapid tests are accurate and useful in clinical settings. Feasibility of the home test as part of disease control and self-management is currently being investigated. Aliment Pharmacol Ther,31, 323,330 [source]

Enhancing multimedia streaming over existing wireless LAN technology using the Unified Link Layer API

INTERNATIONAL JOURNAL OF NETWORK MANAGEMENT, Issue 5 2007
Tim Farnham
This paper examines how multimedia streaming scenarios can be enhanced by cross-layer interaction, and in particular link performance information and configuration options provided by the recently developed Unified Link Layer API (ULLA). It provides results of an experimental implementation developed for this purpose in a wireless LAN (WLAN) environment. Multimedia streaming is an application that is gaining in popularity for mobile devices and in particular mobile Internet-based content broadcasting is rapidly emerging as a key feature on mobile devices. In these scenarios, the wireless link (last hop) is normally the performance bottleneck due to the dynamic and limited capacity of the wireless medium. The use of ULLA in this context can provide the ability to tailor the video transmission to the wireless link performance and also to configure the links in response to performance problems or environmental changes. For this purpose the focus of multimedia streaming has been on WLAN link technology and dynamic adaptation (i.e., dynamic channel selection and video transcoding) using a dynamic resource reservation overlay protocol.

NTT DoCoMo's Launch of I-Mode in the Japanese Mobile Phone Market: A Knowledge Creation Perspective*

JOURNAL OF MANAGEMENT STUDIES, Issue 1 2007
Vesa Peltokorpi
abstract While innovation and knowledge creation processes and context are interlinked in the real world, scholars frequently ignore or separate context from knowing due to an entrenched sense of ontological and analytical dualism. This paper builds on the organizational knowledge creation theory (Nonaka, 1994) to provide a holistic view of contextual innovation and knowledge creation processes. The phenomenon is demonstrated by a longitudinal case description of i-mode mobile Internet innovation at NTT DoCoMo, a Japanese mobile communications company. This case explains how three key managers created and organized an interlinked system of shared contexts, called ba, that enabled the combination and open flow of diverse knowledge and led to the creation and launch of the i-mode mobile Internet, which unites novel technologies and services. Managerial implications and limitations are discussed. [source]

The support of mobile internet applications in UMTS networks through the open service access

BELL LABS TECHNICAL JOURNAL, Issue 2 2001
Musa R. Unmehopa
Third-generation wireless networks are expected to enable the mobile Internet to become a reality, offering fast Internet access and high-speed data services to mobile subscribers. For network operators to allow for the rapid development of innovative value-added applications on the scale seen in the Internet today, the wireless core network needs to be opened up for third-party applications provided by independent software vendors (ISVs). The Third-Generation Partnership Project (3GPP) is currently working on the production of technical specifications to provide a mechanism that would permit ISVs a standard interface to access network capabilities traditionally available to network operators. Within 3GPP, this mechanism is commonly referred to as the open service access (OSA). This open service access is predominantly targeted at Universal Mobile Telecommunications System (UMTS) networks, allowing application developers to access the feature-rich core network capabilities. This open access enables network operators to offer innovative services to their subscribers allowing the ability to differentiate themselves in a competitive market. With the imminent commercial deployment of the General Packet Radio Service (GPRS), existing fixed-line Internet service providers (ISPs) can now offer mobile Internet to end users in a UMTS environment where the responsibility of the network operator is reduced to providing IP connectivity. The increased competition from ISPs poses a big threat to the revenue stream of the network operator. This paper explores the possibilities of OSA to facilitate network operators in providing the mutual support of network capabilities and Internet content. These possibilities would allow the network operator to become a value-added mobile Internet service provider (VAM-ISP). © 2002 Lucent Technologies Inc. [source]
