Nutritional therapy cannot only improve nutritional status but also reduce bowel inflammation in Crohn disease (CD). The benefits of preoperative nutritional therapy on outcomes of surgery for CD have been demonstrated. However, the ideal end-points of preoperative nutrition in CD remain elusive. We conducted this study to figure out whether improvement of malnutrition or reduction of inflammat...

Introduction: The limited resolution of the imaging system causes partial volume effects (PVEs). These results in spreading of image counts to the neighboring pixels. This phenomenon is called spill-out effect. This study aimed at quantifying PVEs using ImageJ. Methods:Technetium-99m solution of concentration of 74 kBq/ml was filled into spheres A, B<...

PURPOSE To determine the reproducibility of TWIST-derived (Time-Resolved Angiography with Interleaved Stochastic Trajectories) quantitative dynamic contrast enhanced (DCE) MRI in a uterine fibroid model. MATERIALS AND METHODS The institutional review board approved this retrospective study. Dynamic contrast-enhanced TWIST datasets from 15 randomly selected 1.5 Tesla pelvic MR studies were pos...

This paper presents an H.264 standard-compliant video encoder optimized for region-of-interest (ROI) based coding and applied to American Sign Language (ASL) videos. Three encoding parameters are developed which allow the encoder to allocate both rate and computational resources differently between the ROI and non-ROI. An objective measure of intelligibility is included in an encoder parameter ...

background : hepatitis b virus (hbv) and hepatitis c virus (hcv) infections are major global public health problems. this study was conducted to investigate the incidence rate of these infections over six successive years in hamadan province, the west of iran. methods: this retrospective cohort study was conducted on the database of hepatitis registry. in this study, 1257 subjects infected by h...

This paper proposes an integrated solution for smart delivery of video surveillance data. The system is developed within the IST project WCAM "Wireless Cameras and AudioVisual Seamless Networking" which is presented as well [1]. The main feature of our system is it includes smart video coding based on automatic scene analysis and understanding. Specifically, the segmentation results are used fo...

Reactive oxygen intermediates (ROI) play an important role in cell signaling in addition to their role in microbial killing. We have shown previously that exogenous ROI regulate activity of the enzyme 5-lipoxygenase (5-LO) in alveolar macrophages (AM). Here, we examined the role of endogenous ROI, specifically generated by NADPH oxidase, in the regulation of leukotriene (LT) synthetic capacity ...

Listeria monocytogenes (Lm) evades being killed after phagocytosis by macrophages by escaping from vacuoles into cytoplasm. Activated macrophages are listericidal, in part because they can retain Lm in vacuoles. This study examined the contribution of reactive oxygen intermediates (ROI) and reactive nitrogen intermediates (RNI) to the inhibition of Lm escape from vacuoles. Lm escaped from vacuo...

OBJECTIVE To determine the return on investment (ROI) of Highmark Inc.'s employee wellness programs. METHODS Growth curve analyses compared medical claims for participants of wellness programs versus risk-matched nonparticipants for years 2001 to 2005. The difference was used to define savings. ROI was determined by subtracting program costs from savings and alternative discount rates were ap...

This paper details work undertaken on the application of JPEG 2000, the recent ISO/ITU-T image compression standard based on wavelet technology, to region of interest (ROI) coding. The paper briefly outlines the JPEG 2000 encoding algorithm and explains how the packet structure of the JPEG 2000 bit-stream enables an encoded image to be decoded in a variety of ways dependent upon the application...
