In this paper we describe a color image segmentation system that performs color clustering in a color space and then color region segmentation in the image domain. For color segmentation, we developed a fuzzy clustering algorithm that iteratively generates color clusters using a uniquely de"ned fuzzy membership function and an objective function for(More)
Neisseria gonorrhoeae (GC) is a human pathogen that adheres to and invades genital surfaces. Although pili are required for the initial adherence, the interaction of GC with epithelial cells is also promoted by a family of outer membrane proteins, the opacity (Opa) proteins such as OpaA protein from strain MS11. Studies have demonstrated that the(More)
This paper describes a fuzzy diagnostic model that contains a fast fuzzy rule generation algorithm and a priority rule based inference engine. The fuzzy diagnostic model has been implemented in a fuzzy diagnostic system for the End-of-Line test at automobile assembly plants and the implemented system has been tested extensively and its performance is(More)
Although the 'ataxia telangiectasia mutated' (ATM) gene plays an important role in physiological processes, such as sensing DNA damage, reducing oxidative stress and protecting telomeres length, little information about ATM and longevity is available. Therefore, we aim to examine the association between genetic variants in promoter of ATM and longevity in(More)
This study aims to investigate the effects of rhBMP-2/ACS composite on bone regeneration and mineralization during expansion of the interparietal suture in rats. Forty 10-week-old Sprague-Dawley rats were divided into four groups (n=10). The first group (intact group) did not receive any intervention. The second group (expansion control group) received an(More)
BACKGROUND Massive wasp stings have been greatly underestimated and have not been systematically studied. The aim of this study was to identify the clinical features and treatment strategies of severe wasp stings. METHODS AND FINDINGS A multicenter retrospective study was undertaken in 35 hospitals and medical centers including 12 tertiary care hospitals(More)
The Pro12Ala polymorphism of PPAR gamma 2 has been shown to influence hypertension and the benefit of longevity in previous studies. We examined whether the polymorphism was related to essential hypertension among long-lived subjects (is greater than 90 years). The Pro12Ala variant was examined using polymerase chain reaction restriction fragment length(More)
