Gallbladder Disorders Detected by Ultrasound

Open Journal of medical Imaging 2014年第2期4卷 86-94页

作者： hamad Elniel h. Eltyib Adel m. Al-Garni Saddig D. Jastaniah Department of Diagnostic Radiology Faculty of Applied Medical Sciences King Abdulaziz University Jeddah KSA

Patients who have disease of the biliary tract commonly present with acute right upper quadrant pain, nausea or vomiting, mid-epigastric pain, and/or jaundice. Etiologies include inflammation with or without infection, noninflammatory disorders, and benign or malignant neoplasms of the gallbladder or bile ducts. Ultrasound (US) is now accepted as the initial imaging modality of choice for the work-up of suspected biliary tract disease. A retrospective study was carried out at King Abdulaziz University hospital to discuss the protocol of ultrasound scanning in demonstrating incidence and complication of Gall-bladder (GB) pathologies. Known cases of GB pathologies (100 patients) were surveyed by ultrasound using spatial digital iU22 Philips Convex probe 3.5 mhz. All patients were evaluated with ultrasonogphy following the international scanning guidelines and protocols. The age of the patients is between (9 - 90) years, 68 Patients (68%) were females and 32 patients (32%) were males. Range of age group of accumulation for gallstone presence was (35 - 50) years in females and above 50 years in males. Incidence of gallbladder pathologies are 59% (female 46% and 13% male). Incidence of gallstone is 37%, and ratio of incidence is between male to female 1:3. Other pathologies of gallbladder were found to be acute cholecystities 12%, chronic cholocystities 5%, sludge 2%, carcinoma of the Gall-bladder 1%, Gall-bladder polyps 1% and Emphysematous choleycystities 1%. Ultransonography is a single imaging modality sufficient for evaluation of patient with suspected gallbladder pathologies (gallstone) which can provide information about the presence of gallstone and more over about site and cause of biliary tract obstruction. Ultrasound is highly sensitive and specific means for diagnosis of the gallbladder disorders.

The upper and lower portions of musa sapientum pseudo-stem sheaths were exposed in four types of treatments： pectin decomposing bacteria, magnesium oxide （mgO）, both pectin decomposing bacteria and mgO and control. The fibre strength properties were tested using SIRIm Standard methods and colour changed using gray scale. The bioaugmentation of pectin decomposing bacteria together with mgO additions were found to enhance retting process and reduced retting periods 52% and yielded better strength on the fibres. The lower portion pseudo-stem sheaths gave the higher strength than upper portion. Colour changed showed that the bioaugmentation of pectin bacteria enhanced the degradation colouring compound in banana fibres.

Control of zinc corrosion in acidic media: Green fenugreek inhibitor

引用

Transactions of Nonferrous metals Society of China 2016年第11期26卷 3034-3045页

作者： Shimaa m.ALI hamedh A.Al LEhAIBI Department of Chemistry Faculty of Science Taibah University Department of Chemistry Faculty of Science Cairo University

Fenugreek seeds extract was examined as a green corrosion inhibitor for Zn in 2.0 mol/L h2SO4 and 2.0 mol/L hClsolutions by mass loss and electrochemical measurements. Scanning electron microscope （SEm） images show that the surfacedamage is decreased in the presence of the inhibitor. X-rays photoelectron spectroscopy （XPS） analysis was performed to identify thecorrosion product, ZnO, and to prove the inhibitor adsorption mechanism. The maximum inhibition efficiency values are 90.7% after1 h and 66.6% after 0.5 h by 200 mL/L of fenugreek extract in h2SO4 and hCl solutions, respectively. Addition of I^- ion greatlyimproves the inhibition efficiency of fenugreek seeds extract for Zn corrosion in hCl due to the synergistic effect. Potentiodynamicpolarization and EIS measurements prove the inhibition ability of fenugreek for Zn corrosion in hCl as indicated by the decreasedcorrosion current density and increased charge transfer resistance values in the presence of fenugreek.

The complexity of prognosis communication in heart failure: Patient and cardiologists’ preferences in the outpatient clinical setting

引用

World Journal of Cardiovascular Diseases 2013年第1期3卷 108-117页

作者： Patricia h. Strachan heather m. Arthur Catherine Demers Robert J. Robson Department medicine Division of Cardiology McMaster University Hamilton Canada Department of Community health Sciences Faculty of Medicine University of Manitoba Winnipeg Canada Faculty of health Sciences McMaster University Hamilton Canada. heart and Stroke Foundation of Ontario Ottawa Canada

Background: The determination of prognosis in heart failure (hF) has focused primarily on the identification of potential biological and physiological markers and not on communication. high morbidity and mortality rates suggest that patients require prognostic information to assist in life planning. This study examined the preferences of both patients with hF and cardiologists for prognosis communication in the outpatient clinical setting, with the aim of guiding practitioners in undertaking prognosis conversations. methods: Using qualitative descriptive techniques informed by a grounded theory approach, 32 patients with hF and 9 cardiologists from outpatient settings in Ontario, Canada were interviewed to identify convergent preferences for prognosis communication. Strategies to enhance methodological rigor were employed. Results: Individualized, context-specific prognosis communication between patients and cardiologists was preferred. Two main themes and ten related attributes were identified to describe convergent preferences;1) Set the Stage for Prognosis Communication, and 2) map the hF route. Attributes reflected the complex, dynamic, interactive and iterative nature of prognosis communication preferences. Conclusions: Prognosis communication occurs within a complex, adaptive healthcare system. While specific preferences exist, changing contextual elements within and outside of the system create conditions that require cardiologists to adjust their approach to individual patients. Patients with hF and cardiologists each have preferences that affect their willingness and ability to engage in dyadic hF-specific prognosis communication. Findings have relevance for the implementation of any efforts, including hF guidelines, aimed at improving prognosis communication. Our findings, informed by a complexity science approach, offer an innovative and robust alternative to traditional linear approaches to prognosis communication.

Nitrogen Fertilization and Inoculation Effects on Dry Bean

引用

Agricultural Sciences 2017年第10期8卷 1065-1081页

作者： Ryan Buetow Grant h. mehring hans Kandel Burton Johnson Juan m. Osorno Department of Plant Sciences North Dakota State University Fargo ND USA

Dry bean (Phaseolus vulgaris L.) has the ability to form symbiotic relationships with N2-fixing bacteria. The research objectives were to evaluate yield and growth differences between dry bean cultivars from black, navy, and pinto market classes, with different N management combinations utilizing urea fertilizer, and two rhizobacteria inoculants. Research was conducted near Park River and Prosper, ND, during 2010, 2012, 2013. The experiment was a RCBD 3 × 2 × 3 factorial with four replicates with three dry bean cultivars, two N fertility levels, and two rhizobacteria inoculum sources plus a non-inoculated treatment. The pinto cultivar was also evaluated in 2014. Results showed significant cultivar main effect differences for nodules per plant, vigor, height, and 1000 seed weight. The pinto cultivar had significantly more nodules per root (19) compared with the black (13) and navy cultivars (9). There were not significant differences between inoculant treatments. The fertilizer main effect indicated significant differences for vigor and 1000 seed weight. No significant interactions were detected among factors. Addition of 56 kg N ha-1 resulted in more vigorous plants, but had no effect on seed yield, and reduced 1000 seed weight at harvest at Park River in 2013. Root nodule number was higher with the inoculant treatments with 16.2 and 15.8 nodules per plant compared to the non-inoculated treatment with 10.7 nodules per plant at Park River in 2013. The pinto variety Lariat with an application of 56 kg ha-1 had visually greener plants in 2013 and 2014, except Park River in 2013, but SPAD readings were not following the same trend. Inoculation and application of N fertilizer on dry bean may not be necessary if rhizobacteria are present and soil N levels are sufficiently high but future research on rates, timing, and N source and appropriate strains of Rhizobia inoculant on other pinto varieties is suggested.

河流有机污染是我国目前特别严重的环境污染问题之一。可以采用化学或生物监测的方法进行评价。首次采用大型底栖动物BmWP(BiologicalmonitoringWorkingParty)系统方法,对广州珠江前航道、西航道和流溪河下游段共3个河段进行有机污染生物监测评价。结果显示:底栖动物在3河段间分布确有显著性差异,根据修正的BmWP分数可以判断流溪河水质相对较好,水质级别相应于中国地表水环境质量标准Ⅳ～Ⅴ级,西航道和前航道水质级别均为Ⅴ级。通过测试这一方法能成功地应用在珠江及流溪河,且修正后的ISO＿BmWP法可以较好地匹配于我国地表水5级评价系统,因此,初步认为修正后的ISO＿BmWP系统可以成为一个和化学监测互补的好方法,从而应用于中国河流的生物监测评价。
