AIM： To search the pathophysiological mechanism of diarrhea based on daily stool weights, fecal electrolytes, osmotic gap and pH. METHODS： Seventy-six patients were included： 51 with microscopic colitis （MC） [40 with lymphocytic colitis （LC）; 11 with collagenous colitis （CC）], 7 with MC without diarrhea and 18 as a control group （CG）. They collected stool for 3 d. Sodium and potassium concentration were determined by flame photometry and chloride concentration by titration method of Schales. Fecal osmotic gap was calculated from the difference of osmolarity of fecal fluid and double sum of sodium and potassium concentration. RESULTS： Fecal fluid sodium concentration was significantly increased in LC 58.11±5.38 mmol/L （P〈0.01） and CC 54.14±8.42 mmol/L （P〈0.05） than in CG 34.28±2.98 mmol/L. Potassium concentration in LC 74.65±5.29 mmol/L （P〈0.01） and CC 75.53±8.78 mmol/L （P〈0.05） was significantly less compared to CG 92.67±2.99 mmol/L. Chloride concentration in CC 36.07±7.29 mmol/L was significantly higher than in CG 24.11±2.05 mmol/L（P〈0.05）. Forty-four （86.7%） patients had a secretory diarrhea compared to fecal osmotic gap. Seven （13.3%） patients had osmotic diarrhea. CONCLUSION： Diarrhea in MC mostly belongs to thesecretory type. The major pathophysiological mechanism in LC could be explained by a decrease of active sodium absorption. In CC, decreased CI/HCO3 exchange rate and increased chloride secretion are coexistent pathways.

The description in the abstract lacks clear logic and a comprehensive summary of this study, so please revise and improve it according to the design theme and main content of this study, and describe it in the order of (research background), purpose/aim, method, results and conclusions. The introduction of the abstract and preface is rather lengthy, but the summary of the whole study and the presentation of the research background are not perfect (mainly because the logic of the context is not clear and orderly), so it will appear a bit messy. Hope to be able to modify (this has been mentioned in the preliminary opinion). Cardiovascular events (CVE) pose a significant threat to individuals with end-stage renal disease (ESRD), yet these patients are often excluded from cardiovascular clinical trials, leaving prognostic factors associated with CVE in ESRD patients largely unexplored. Recent human studies have demonstrated elevated circulating aldosterone levels in ESRD patients, correlating with left ventricular hypertrophy. Additionally, animal models have shown improvements in uremic cardiomyopathy with spironolactone therapy, prompting interest in assessing the efficacy of spironolactone or eplerenone in reducing mortality and improving cardiovascular function in dialysis patients. Clinicians have historically been cautious about prescribing mineralocorticoid receptor antagonists (MRAs) to congestive heart failure patients with chronic kidney disease (CKD) due to hyperkalemia risk. However, the emergence of finerenone, a novel MR antagonist with a favorable safety profile and lower hyperkalemia risk, has renewed interest in MRA therapy in this population. Heart disease, including coronary artery disease, hypertension, and left ventricular failure, is alarmingly prevalent in dialysis patients, contributing significantly to elevated mortality rates compared to the general population. Arterial stiffness, as indicated by pulse wave velocity (PWV), progressively worsens

Effect of abutment modeling on the seismic response ofbridge structures

引用

Earthquake Engineering and Engineering Vibration 2008年第4期7卷 395-402页

Abutment behavior significantly influences the seismic response of certain bridge structures. Specifically in the case of short bridges with relatively stiff superstructures typical of highway overpasses, embankment mobilization and inelastic behavior of the soil material under high shear deformation levels dominate the response of the bridge and its column bents. This paper investigates the sensitivity of bridge seismic response with respect to three different abutment modeling approaches. The abutment modeling approaches are based on three increasing levels of complexity that attempt to capture the critical components and modes of abutment response without the need to generate continuum models of the embankment, approach, and abutment foundations. Six existing reinforced concrete bridge structures, typical of Ordinary Bridges in California, are selected for the analysis. Nonlinear models of the bridges are developed in OpenSees. Three abutment model types of increasing complexity are developed for each bridge, denoted as roller, simplified, and spring abutments. The roller model contains only single-point constraints. The spring model contains discrete representations of backfill, bearing pad, shear key, and back wall behavior. The simplified model is a compromise between the efficient roller model and the comprehensive spring model. Modal, pushover, and nonlinear dynamic time history analyses are conducted for the six bridges using the three abutment models for each bridge. Comparisons of the analysis results show major differences in mode shapes and periods, ultimate base shear strength, as well as peak displacements of the column top obtained due to dynamic excitation. The adequacy of the three abutment models used in the study to realistically represent all major resistance mechanisms and components of the abutments, including an accurate estimation of their mass, stiffness, and nonlinear hysteretic behavior, is evaluated. Recommendations for abutment modeling

作者： Mirko Zganjer Ante Cizmic Irenej Cigit bozidar Zupancic Igor Bumci Ljiljana Popovic Antun Kljenak Department of Paediatric Surgery Children's Hospital Zagreb Klai eva 16 Zagreb 10000Croatia

AIM:To evaluate the role and our experience of injecti-on sclerotherapy with cow milk in the treatment of rectal prolapse in children. METHODS:In the last 30 years (1976-2006) we made 100 injections of sclerotherapy with cow milk in 86 chil-dren. In this study we included children who failed to respond to conservative treatment and we perform ope-rative treatment. RESULTS:In our study we included 86 children and in all of the patients we perform cow milk injection sclerot-herapy. In 95.3% (82 children) of patients sclerotherapy was successful. In 4 (4.7%) patients we had recurrent rectal prolapse where we performed operative treatment. Below 4 years we had 62 children (72%) and 24 older children (28%). In children who needed operative trea-tment we performed Thiersch operation and without any complications. CONCLUSION:Injection sclerotherapy with cow milk for treatment rectal prolapse in children is a simple and effective treatment for rectal prolapse with minimal com-plications.

Journal of Energy and Power Engineering 2014年第7期8卷 1333-1340页

作者： Bosko Milesevic bozidar Filipovic-Grcic Tomislav Radosevic Faculty of Electrical Engineering and Computing University of Zagreb Zagreb 10000 Croatia Ravel Ltd. Brajkovikev prilaz 13 Zagreb 10000 Croatia

Various regulations, aimed at the protection of human beings and electrical equipment against possible adverse effects resulting from exposure to electromagnetic fields, have been issued in many countries. Most of them are based on safety guidelines published by international expert groups. In this paper, electric and magnetic fields are calculated in the vicinity of 25 kV traction line supplying railway traction systems. Calculation results are compared to exposure limits specified by safety guidelines and regulations. Possible countermeasures for reduction of electromagnetic fields are proposed. Also, this paper presents a method for calculation of the induced voltages to an underground gas pipeline from a neighbouring 25 kV electric traction overhead line in case of short circuit. Calculations are performed with EMTP-ATP software. Possible countermeasures for reduction of induced voltages are proposed.

The effect of detergent as polluting agent on the photosynthetic activity and chlorophyll content in bean leaves

引用

Health 2010年第5期2卷 395-399页

作者： Branislav R. Jovanic Srdjan Bojovic Bratimir Panic bozidar Radenkovic Marijana Despotovic 不详

The paper investigates effects of detergent for domestic use on the photosynthetic activity and chlorophyll content in intact bean leaves. The plants were watered for 21 days with a solution of domestic washing powder of 0.60 g r/l. It was established that the activity of photosynthetic apparatus in the plant leaf PhACNorm [%] decreases exponentially with the length of plant treatment/watering. At the end of the treatment (21st day) the activity of photosynthetic apparatus in the dosed plant leaf was no more than 45% of that in control plant (those which were not watered with detergent solution). With increased plant treatment duration the changed chlorophyll concentration ΔChlNorm [%] rose non-linearly in plant leaves. The highest change ΔChlNorm [%] was observed on the 21st day and amounted to 12%.
