Modern Plastic Surgery (MPS) , 2014, DOI: 10.4236/mps.2014.42007

We report a case of a 37-year-old Japanese female. She had a Tessier no. 8 craniofacial cleft and an orbital lipoma in the lateral canthal region. Excisional surgery and pathological examination revealed a genuine lipoma. No other case has been reported in the literature. Here, we present our case of a rare genuine lipoma located in lateral canthal region of the Tessier no. 8 cleft.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0083799
Abstract: Background Advanced glycation end product (AGE) accumulation is thought to be a measure of cumulative metabolic stress that has been reported to independently predict cardiovascular disease in diabetes and renal failure. The aim of this study was to evaluate the association between AGE accumulation, measured as skin autofluorescence, and the progression of renal disease in pre-dialysis patients with chronic kidney disease (CKD). Methods Skin autofluorescence was measured noninvasively with an autofluorescence reader at baseline in 449 pre-dialysis patients with CKD. The primary end point was defined as a doubling of serum creatinine and/or need for dialysis. Results Thirty-three patients were lost to follow-up. Forty six patients reached the primary end point during the follow-up period (Median 39 months). Kaplan-Meier analysis showed a significantly higher risk of development of the primary end points in patients with skin autofluorescence levels above the optimal cut-off level of 2.31 arbitrary units, derived by receiver operator curve analysis. Cox regression analysis revealed that skin autofluorescence was an independent predictor of the primary end point, even after adjustment for age, gender, smoking history, diabetes, estimated glomerular filtration rate and proteinuria (adjusted hazard ratio 2.58, P = 0.004). Conclusions Tissue accumulation of AGEs, measured as skin autofluorescence, is a strong and independent predictor of progression of CKD. Skin autofluorescence may be useful for risk stratification in this group of patients; further studies should clarify whether AGE accumulation could be one of the therapeutic targets to improve the prognosis of CKD.
An Empirical Investigation of Common Sense of Land Use from a Statistical Approach  [PDF]

Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.42014
Abstract: Recently, ontological study has been one of the key concerns of geographic information science, a number of studies have been conducted in both of philosophical and knowledge engineering approach. Some studies pointed out the importance of human cognition and social context for development of ontologies. This paper presents empirical investigation of common sense of land use categories for development of suitable ontologies for each cultural or speech communities. Distinctions and characteristics in perceiving land use categories were described by a psychological method that was submitted to Japanese graduate and undergraduate students. In addition the results were analyzed using corresponddence analysis, a statistical technique for categorical data. This analysis serves to clarify the dominant determining factors for land use categories.
Synthesis of Branch-Type Cyclophane Tetramers Having a Multivalently Enhanced Guest-Binding Ability  [PDF]
Osamu Hayashida, Chihiro Nada, Shuhei Kusano
Advances in Chemical Engineering and Science (ACES) , 2019, DOI: 10.4236/aces.2019.91006
Abstract: A cationic branch-type cyclophane tetramer (1a) was synthesized by introducing three Boc-protected cyclophane derivatives into a N-acetylated tetraaza[]paracy-clophane derivative as a core skeleton through DCC condensation, followed by removal of the external Boc-protecting groups. Cationic cyclophane tetramer 1a exhibited a high affinity toward an anionic and hydrophobic fluorescent guest, TNS, with binding constant of 4.8 × 105 M-1. This value of 1a was about 80-fold larger than that of the corresponding monomeric cyclophane for the identical guest, reflecting multivalent effect on the guest binding. As for electrostatic recognition, the obtained binding constant of 1a was one order of magnitude larger than that of an analogous anionic cyclophane tetramer (1b) for the identical guest. These enhanced guest-binding abilities of 1a were easily evaluated by fluorescence titration experiments.

Coverage Criterion in Sensor Networks Stable under Perturbation
Yasuaki Hiraoka,Genki Kusano
Mathematics , 2014,
Abstract: To the coverage problem of sensor networks, V. de Silva and R. Ghrist (2007) developed several approaches based on (persistent) homology theory. Their criteria for the coverage are formulated on the Rips complexes constructed by the sensors, in which their locations are supposed to be fixed. However, the sensors are in general affected by perturbations (e.g., natural phenomena), and hence the stability of the coverage criteria should be also discussed. In this paper, we present a coverage theorem stable under perturbation. Furthermore, we also introduce a method of eliminating redundant cover after perturbation. The coverage theorem is derived by extending the Rips interleaving theorem studied by F. Chazal, V. de Silva, and S. Oudot (2013) into an appropriate relative version.
Simulation of Human Phonation with Vocal Nodules  [PDF]
Shinji Deguchi, Yuki Kawahara
American Journal of Computational Mathematics (AJCM) , 2011, DOI: 10.4236/ajcm.2011.13022
Abstract: The geometric and biomechanical properties of the larynx strongly influence voice quality and efficiency. A physical understanding of phonation natures in pathological conditions is important for predictions of how voice disorders can be treated using therapy and rehabilitation. Here, we present a continuum-based numerical model of phonation that considers complex fluid-structure interactions occurring in the airway. This model considers a three-dimensional geometry of vocal folds, muscle contractions, and viscoelastic properties to provide a realistic framework of phonation. The vocal fold motion is coupled to an unsteady compressible respiratory flow, allowing numerical simulations of normal and diseased phonations to derive clear relationships between actual laryngeal structures and model parameters such as muscle activity. As a pilot analysis of diseased phonation, we model vocal nodules, the mass lesions that can appear bilaterally on both sides of the vocal folds. Comparison of simulations with and without the nodules demonstrates how the lesions affect vocal fold motion, consequently restricting voice quality. Furthermore, we found that the minimum lung pressure required for voice production increases as nodules move closer to the center of the vocal fold. Thus, simulations using the developed model may provide essential insight into complex phonation phenomena and further elucidate the etiologic mechanisms of voice disorders.
A Study of Service Desk Setup in Implementing IT Service Management in Enterprises  [PDF]
Xiaojun Tang, Yuki Todo
Technology and Investment (TI) , 2013, DOI: 10.4236/ti.2013.43022
Abstract: Information Technology Service Management (ITSM) provides a framework to provide IT related services and the interaction of IT staff with users, and is often related with the British Government’s Information Technology Infrastructure Library (ITIL). ITIL offers a set of “best practices” for managing IT services and is one of the most widely accepted approaches to IT service management in the world. Recently, more and more enterprises implemented a centralized IT service management model based on the ITIL framework. However, even by adopting ITIL, most of the enterprises didn’t improve their IT service management level. Some factors become the barriers to the success of ITIL and ITSM implementation. In some cases, enterprises paid more attention to IT infrastructure setup and operation but neglect the importance of Service Desk. In this study, we first review ITSM, ITIL and Service Desk. Second, we identify a full function of new Service Desk and how to setup a good Service Desk. Enterprises should take proper measures in building a mature Service Desk to ensure successful implementation of ITSM.
