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.

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.

Background and Purpose Effect of endovascular therapy (EVT) in acute large vessel occlusion (LVO) patients with tandem lesions (TLs) within 6–24 hours after last known well (LKW) remains unclear. We evaluated the clinical and safety outcomes among TL-LVO patients treated within 6–24 hours. Methods This multicenter cohort was divided into two groups, based on LKW to puncture time: early window (<6 hours), and late window (6–24 hours). Primary clinical and safety outcomes were 90-day functional independence measured by the modified Rankin Scale (mRS: 0–2) and symptomatic intracranial hemorrhage (sICH). Secondary outcomes were successful reperfusion (modified Thrombolysis in Cerebral Infarction score ≥2b), first-pass effect, early neurological improvement, ordinal mRS, and in-hospital and 90-day mortality. Results Of 579 patients (median age 68, 32.1% females), 268 (46.3%) were treated in the late window and 311 (53.7%) in the early window. Late window group had lower median National Institutes of Health Stroke Scale score at admission, Alberta Stroke Program Early Computed Tomography Score, rates of intravenous thrombolysis, and higher rates for perfusion imaging. After adjusting for confounders, the odds of 90-day mRS 0–2 (47.7% vs. 45.0%, adjusted odds ratio [aOR] 0.71, 95% confidence interval [CI] 0.49–1.02), favorable shift in mRS (aOR 0.88, 95% CI 0.44–1.76), and sICH (3.7% vs. 5.2%, aOR 0.56, 95% CI 0.20–1.56) were similar in both groups. There was no difference in secondary outcomes. Increased time from LKW to puncture did not predicted the probability of 90-day mRS 0–2 (aOR 0.99, 95% CI 0.96–1.01, for each hour delay) among patients presenting <24 hours. Conclusion EVT for acute TL-LVO treated within 6–24 hours after LKW was associated with similar rates of clinical and safety outcomes, compared to patients treated within 6 hours.

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.
