Dear editor, During the past two decades, management of blunt solid organ injuries had shifted from conventional surgery to more conservative approach, namely nonoperative management (NOM).[1] The non-operative approach mainly depends on the trauma experience of surgeons and the institution, quality of radiographic imaging and its interpretation.[2-5] If the surgeon decides to observe the patients by NOM, close monitoring of vital signs and frequent physical examinations must be done accordingly with radiological evaluations if needed.

Is Outpatient Follow-Up of Epiploic Appendagitis with NSAIDs Alone and Noantibiotics Possible?

Open Journal of Gastroenterology 2014年第4期4卷 170-174页

Purpose: To assess the clinical course of patients diagnosed as having “epiploic appendagitis” who are given only NSAIDs without antibiotic treatment. Materials and Methods: Between December 2010 and November 2013, twelve patients were presented to the Emergency Surgery Department, Istanbul Medical Faculty, Istanbul University with abdominal pain and were diagnosed having “epiploic appendagitis”. The diagnoses were made using the information gathered from patients’ complaints, physical examination, biochemical results, and radiologic images (Abdominal X-Ray, Abdominal Ultrasonography [USG], and Contrast-Enhanced Computerized Tomography [CT]). We evaluated and recorded the patients’ age distribution, sex difference, laboratory results, radiologic images, length of hospital stay, and control exams after discharge. Results: Twelve out of 35,574 (0.033%) patients who were presented to our Emergency Surgery Department with abdominal pain and were hospitalized as “epiploic appendagitis”. Of these 12 patients, 7 were male (58.3%), and 5 were female (41.7%). The mean age of the patients was 43.5 (range: 22 to 60). The mean time passed between the beginning of the symptoms and presentation to the hospital was 1 day. The length of hospital stay was 1 to 2 days with a mean of 1.3 days. All patients were followed-up non-invasively under NSAID treatment without antibiotherapy. No complications were observed throughout the hospitalization period. The follow-up period of the patients was between 2 to 31 months with a mean of 16 months. Conclusion: Epiploic appendagitis is a self-limiting, benign disease, but differential diagnosis should be done carefully. Patients who are diagnosed with epiploic appendagitis may be followed-up with NSAIDs alone without hospitalization or antibiotherapy.

Toppling and sliding in volcanic bimrocks around Bayrakli(Izmir, Turkey)

Journal of Mountain Science 2020年第2期17卷 492-500页

Discontinuities have significant role on the behavior of rock masses with respect to several types of instabilities. Excavability, deformability, bearing capacity and slope stability of the rock masses should be investigated considering the discontinuity characteristics with particular emphasis on the geomechanical properties. Kinematic analyses mostly provide an insight to the instabilities, however the dimensions of the blocks bounded by discontinuities, their geomechanical properties and the geometry of the slope should also to be taken into account. The study area is in the abandoned stone quarry in Bayrakl? district of ?zmir residential area. Due to the excavations and discontinuity orientations, instabilities have occured. Miocene aged andesites and altered agglomerates of Yamanlar Volcanics form the bimrock mass. The study area is located within a sheared zone, bounded by strike slip fault zone. Intact andesite blocks were encountered in altered agglomerate matrix, forming a volcanic bimrock. Wedge and planar sliding and block toppling were observed within the area. Detailed discontinuity surveying was conducted, combined with core drillings. Several typical locations were detected where prismatic blocks of andesites are bound to experience block toppling. Such locations are nearby the top of the steep slopes. Agglomerates are subjected to mainly sliding and the blocks have been formed not by gravity but by peculiarities of thevolcanic sedimentation and, probably by subsequent tectonics. In order to determine the mechanism of the sliding and toppling in more details, the relation of the blocks and the slope geometry were investigated. Bimrock type volcanic rock masses sometimes do not tend to accommodate the general rules of toppling and sliding due to their anisotropic settings.

Toxicity, inheritance and biochemistry of clofentezine resistance in Tetranychus urticae

Insect Science 2011年第5期18卷 503-511页

This study evaluates the toxicological and biochemical response of two-spotted spider mites to clofentezine selection pressure. The mortality rate of Tetranychus urticae in adult females depends on increased clofentezine concentration and clofentezine was found to be effective against females. The resistance rate of the CUM strain selected 12 times once per generation with clofentezine was increased from 1.28- to 105.27-fold. The interaction of some synergists with clofentezine was analyzed in the clofentezine-resistant CLOF 12 strain. Synergists had no effect on clofentezine toxicity. The clofentezine-resistant CLOF 12 strain showed resistance against chlorpyrifos, abamectin, propargite, fenpyroximate and amitraz. The modes of inheritance of resistance to clofentezine were found to be incompletely dominant and not sex-linked. Esterase enzyme activity was detected both by gel electrophoresis and microplate reader methods, while glutathione S-transferase （GST） and monooxygenase （P450） activity were detected only by the microplate reader method. During the selection period the esterase, the GST and the P450 enzymes activities were raised from 7.69, 7.09 and 0.003 3 to 18.40, 13.11 and 0.003 7 milli-optical density/rain/rag proteins, respectively. An increase was observed in the band intensity of esterases and esterase enzymes may play a role in clofentezine resistance in T. urticae.

An electrochemical and microstructural characterization of steel-mortar admixed with corrosion inhibitors

引用

Science China(Technological Sciences) 2009年第1期52卷 52-66页

The present research brings new insights on the role of admixed corrosion inhibitors in the processes of cement hydration and rebar corrosion. The admixing of NaCl and the corrosion inhibitors in fresh mortar was found to alter the morphology and microstructure of the hardened mortar at the steel-mortar interfacial region. The admixing of the inhibitors increased the risk of carbonation of cement hydrates at the steel-mortar interfacial region, but partially displaced chloride ions. Chloride and the admixed inhibitors facilitated the formation of different cement hydrates and affected chloride binding at the steel-mortar interfacial region. The admixing of all three inhibitors was found to increase the polarization resistance of steel, indicating reduced corrosion rate of the steel over 48-day exposures to salt ponding.
