Although similar in many respects, the two major Christian universities in Republican China adopted markedly different approaches to the common challenge of student nationalism. Case studies of the May Thirtieth Movement at St. john＇s University and the December Ninth Movement at Yenching University illustrate the consequences of these sharply contrasting experiences. Whereas St. john＇s was crippled by May Thirtieth, Yenching escaped December Ninth relatively unscathed. The explanation for the contrast, this paper suggests, lies not in any fundamental disagreement in the mission of the two universities or the philosophies of their famous and forceful presidents. It must be sought instead in the different campus cultures in which the student protests originated, and in the urban micro-environments in which the two universities were located： treaty-port Shanghai and post-imperial Peking.

Sickle cell disease (SCD) has been regarded as an inflammatory and pro-?coagulatory disease with profound cardiovascular abnormalities including propensity for ventricular arrhythmogenesis. Tp-e and Tpe/QTc ratio however has?been proposed as better indicators of arrythmogenesis and has?been shown to be prolonged in many inflammatory conditions and correlate with levels of inflammatory markers. However, correlation between Tpe/QTc ratio and the level of highly sensitive C-reactive protein (hs-CRP) and plasminogen activator inhibitor (PAI) have not been reported in SCD. This study aims at evaluating Tp-e Interval and Tp-e/QTc ratio among steady state Sickle cell disease patients in relationship to the degree of anaemia, inflammatory and profibrotic markers.?Methodology:?A cross-sectional hospital-based study comprises?30 sickle cell anaemia patients in steady state with an?equal number of controls having genotype HbAA and HbAS ***, laboratory and ECG parameters were obtained.?Results:?A total of 90 participants?are?with mean age 24.2?±?5.6. The study showed that sickle cell disease patient had significantly lower level of PCV and higher level of PAI, platelet and total white cell count (p value??0.05). C-reactive protein was also higher in them. 76.7% of HbSS patients had abnormal ECG. QTc and Tp-e were also prolonged in sickle cell disease patients compared with controls. An association was found between the level of PCV, PAI and prolonged Tp-e and QTc.?Conclusion:?Sickle cell disease patients have higher levels of inflammatory markers and abnormal ECG patterns are common in them. Moreover, the levels of these inflammatory markers correlate with Tp-e parameters.

The purpose of the study was to develop pedotransfer functions for determining saturated hydraulic conductivity (Ks). Pedotransfer functions (PTFs) for predicting soil physical properties used in determining saturated hydraulic conductivity, based on moisture retention characteristics, were developed. The van Genuchten moisture retention equation was fitted to measured moisture retention properties obtained from International Soil Reference and Information Centre (ISRIC) soils data base in order to determine parameters in the equation i.e. saturated soil moisture content (θs), residual soil moisture (θr), air entry parameter (α) and the pore size distribution parameter (n). 457 samples drawn from the data base were used to be the maximum possible sample size that contained the measured soils characteristics data required. Using statistical regression, mathematical relationships were developed between moisture retention parameters (response variables) and appropriately selected transformed basic soil properties (predictor variables). The developed PTFs were evaluated for accuracy and reliability. It was found that pedotransfer functions developed for θs produced the best performance in reliability compared to the remaining parameters yielding a correlation coefficient value of coefficient of determination (R2 = 0.76), RMSE = 2.09, NSE = 0.75 and RSR = 0.5 indicating good performance. Relatively poorest performance was obtained from the pedotransfer function developed for α which yielded a correlation coefficient, R2= 0.06, RMSE = 0.85 and a NSE of 0.02 reflecting the best possible equation derived for the parameter for use in predicting hydraulic conductivity. Out of the pedotransfer functions developed for each of the moisture retention parameters, the best performing PTF was identified for each parameter. The accuracy of the pedotransfer functions assessed based on R2 were for θs (R2 = 0.80), θr (R2 = 0.42), α (R2 = 0.04) and for n (R2 = 0.30), when the variables w

Aim: To evaluate the effect of tamoxifen citrate on male reproductive system of rat. Methods: Groups of male rats were gavaged with tamoxifen at doses of 200 mg·kg-1·d-1, 400 mg·kg-1·d-1 or 800 mg·kg-1·d-1 in 0.1 mL olive oil for 10 consecutive days. Controls were treated with 0.1 mL olive oil. Rats were anesthetized and killed on d 3, d 15 or d 35 after the last dose. Testes were collected, processed for paraffin embedding, sectioned at 5 μm thickness, stained with H&E and analyzed microscopically. Results: There was a dose-dependent increase in the occurrence of seminiferous tubular distortion with germinal cell sloughing. The highest dose increased the number of multinucleated giant cells on d 3 and d 15. Conclusion: Tamoxifen citrate induces multinucleated giant cells and germinal epithelial sloughing in a dose-dependent manner and these changes are detrimental to male fertility.
