While the success or failure of carpal tunnel release ultimately depends on the interplay of a wide array of factors, a broad understanding of the normal anatomy of the carpal tunnel accompanied by awareness of the possible variations of the individual structures that make up its contents is crucial to optimizing surgical outcomes. While anatomic variants such as extension of the flexor digitorum muscle bellies have been described as a cause of primary carpal tunnel syndrome (CTS), there have been no reports depicting its association with recurrent CTS following initially successful carpal tunnel release, a finding with potentially significant prognostic implications that can aid in operative planning. In such cases where muscle extension is identified preoperatively, careful debulking of the muscle belly may be beneficial in improving long-term surgical outcomes.
Flood Disaster Risk Simulation in Urban Areas in Chaclacayo district, Peru
Castillo Osorio, Ever Enrique,Yoo, Hwan Hee 대한공간정보학회 2018 대한공간정보학회지 Vol.26 No.2
Many urban areas are vulnerable to hazards produced by natural disasters specially floods that are currently increasing. For this reason, prevention efforts must focus on reducing disaster risks when they happen. These actions are applied to land areas; therefore the geographic data are valuable to improve them, because they give the spatial location of the elements in the terrain. Likewise, the hydrological simulation models provide a perspective of the possible vulnerable areas impacted by floods. In order to achieve the improvement of flood disaster risk prevention activities, we propose a methodology for the hydrological simulation of flood scenarios using HecRAS tool. In this methodology we define the geometrical conditions of the cartographic data, use Gumbel`s distribution method for the processing of hydrological data, and develop the hydrological simulation process applying geomorphological and fluid mechanics parameters. The results of the hydrological simulation and the cartographic data are stored in a flexible geodatabase designed by us, using standards and protocols based on open source, which allows their collection, processing and dissemination. We apply the proposed methodology to a case study and develop the hydrological modeling for three simulation scenarios, to calculate the flooding urban areas in Chaclacayo district located in Peru.

Adherence and invasion to cells are the key processes during infection development by Campylobacter jejuni (C. jejuni). In this study, extracts from the byproducts of Citrus limon, Citrus aurantium, and Citrus medica were added to the cultures of C. jejuni, and the adherence and invasion of C. jejuni to HeLa cells and the expression of cadF and ciaB genes were analyzed. The relative expression of the genes was determined by quantitative reverse transcription PCR (qRT-PCR). The antioxidant activity was determined using spectrophotometric methods. Byproduct extracts at subinhibitory concentrations affected the adherence (reduced 2.3 to 99%) and invasion (reduced 71.3 to 99.2%) to the HeLa cells. The expression of cadF and ciaB was reduced from 66 to 99% and from 81 to 99%, respectively. The total phenolic content of the byproducts varied from 92 to 26 mg GAE/g and the total flavonoids varied from 161 to 29.29 mg QE/g. C. aurantium showed the highest percentage of radical scavenging activity (RSA, 90.1). These extracts can prove as effective alternatives for devising new strategies to control Campylobacter infections.
Hybrid PSO-Complex Algorithm Based Parameter Identification for a Composite Load Model
Del Castillo, Manuelito Y. Jr.,Song, Hwachang,Lee, Byongjun The Korean Institute of Electrical Engineers 2013 Journal of Electrical Engineering & Technology Vol.8 No.3
This paper proposes a hybrid searching algorithm based on parameter identification for power system load models. Hybrid searching was performed by the combination of particle swarm optimization (PSO) and a complex method, which enhances the convergence of solutions closer to minima and takes advantage of global searching with PSO. In this paper, the load model of interest is composed of a ZIP model and a third-order model for induction motors for stability analysis, and parameter sets are obtained that best-fit the output measurement data using the hybrid search. The origin of the hybrid method is to further apply the complex method as a local search for finding better solutions using the selected particles from the performed PSO procedure.
Comparative Sequence Analysis of a Multidrug-Resistant Plasmid from Aeromonas hydrophila
del Castillo, Carmelo S.,Hikima, Jun-ichi,Jang, Ho-Bin,Nho, Seong-Won,Jung, Tae-Sung,Wongtavatchai, Janenuj,Kondo, Hidehiro,Hirono, Ikuo,Takeyama, Haruko,Aoki, Takashi American Society for Microbiology 2013 Antimicrobial agents and chemotherapy Vol.57 No.1
<B>ABSTRACT</B><P>Aeromonas hydrophilais a pathogenic bacterium that has been implicated in fish, animal, and human disease. Recently, a multidrug resistance (MDR) plasmid, pR148, was isolated fromA. hydrophilaobtained from a tilapia (Oreochromis niloticus) farm in Thailand. pR148 is a 165,906-bp circular plasmid containing 147 coding regions showing highest similarity to pNDM-1_Dok1, an MDR plasmid isolated from a human pathogen. pR148 was also very similar to other IncA/C plasmids isolated from humans, animals, food, and fish. pR148 contains a mercuric resistance operon and encodes the complete set of genes for the type 4 secretion system. pR148 encodes a Tn<I>21</I>type transposon. This transposon contains the drug resistance genes<I>qacH</I>,<I>bla</I>OXA-10,<I>aadA1</I>, and<I>sul1</I>in a class 1 integron;<I>tetA</I>and<I>tetR</I>in transposon Tn<I>1721</I>; and<I>catA2</I>and a duplicate<I>sul1</I>in a locus showing 100% similarity to IncU plasmids isolated from fish. The<I>bla</I>OXA-10and<I>aadA1</I>genes showed 100% similarity to those from theAcinetobacter baumanniiAYE genome. The similarity of pR148 to a human pathogen-derived plasmid indicates that the plasmids were either transferred between different genera or that they are derived from a common origin. Previous studies have shown that IncA/C plasmids retain a conserved backbone, while the accessory region points to lateral gene transfer. These observations point out the dangers of indiscriminate use of antibiotics in humans and in animals and the necessity of understanding how drug resistance determinants are disseminated and transferred.</P>
