Although the carbendazim is widely used to manage spot blight in celery cultivation, information on residues identified is of interest. In this study, we examined the dissipation and residual amounts of carbendazim in celery and soil under different cultivation methods when using the suggested dose and ten times of that and the bioconcentration factor of carbendazim for celery. The results showed that when celery leaves were sprayed with the suggested dose, the half-lives in a celery field and greenhouse were 2.75 days and 3.29 days, respectively. When the soil matrix was sprayed with the recommended dose before cultivation, the half-lives of carbendazim residues were 16.86 days and 11.97 days. We also conducted a long-term dietary risk assessment using the corresponding criteria. The results showed that, in China, the use of carbendazim at a dose of 0.022 g/m2 is safer and more reasonable when the harvest interval is 28 days.

IntroductionThe present study aimed to compare the torsional strength of the initial files of the Mtwo (VDW, Munich, Germany) and novel Rotate systems (VDW, Munich, Germany) with the ProGlider (Dentsply Sirona, Ballaigues, Switzerland) and R-Pilot (VDW) glide path instruments.MethodsThe Mtwo (10/.04), ProGlider (16/.02), R-Pilot (12.5/.04), and Rotate (15/.04) glide path files were compared regarding their torsional strength, which was tested using a specially designed test device (N = 20). The data obtained were statistically analyzed at 5% significance level using 1-way analysis of variance and the post hoc Tukey test. The fragment surfaces and separated instruments were examined with ×50, ×100, and ×1000 magnification under a scanning electron microscope.ResultsThe R-Pilot group showed the highest torsional strength value among all groups (P < .05), whereas there was no significant difference between the torsional strength values of the Mtwo and ProGlider groups (P > .05). The Rotate group had the lowest torsional strength among all groups (P < .05). The Mtwo group showed the lowest angle of rotation among all groups (P < .05).ConclusionsAlthough the R-Pilot glide path file exhibited the highest torsional strength in all groups, Rotate showed the highest angle of rotation. Differences in torsional resistance of the instruments may be associated with their manufacturing methods and design features. 相似文献
We aimed to propose a practical selection method predicting the easier radical perineal prostatectomy (RPP) cases before the operation.
Methods
Fifty sequential RPP cases were divided into two groups according to the estimated difficulty of the operation (Group I: Easier, Group II: Difficult) which was assessed by using a RPP difficulty scale, constituted by three parameters (operation time, blood loss, and the judgment of the surgeon) each ranging between 1 and 3 points. As the localization parameters, skin-to-prostatic apex (SPAD) and skin-to-prostatic base (SPBD) distances and distance between bilateral ischial tuberosities (ITD) were measured. During suprapubic ultrasonography, a probe-divergence angle (PDA) and prostate volumes (PV) were recorded. These parameters were compared between the groups.
Results
In Group I (n = 29) and Group II (n = 21), the difficulty scores were 4.37 (3–5) and 6.80 (6–9), respectively. Data of age, clinical stages, and findings of digital rectal examination were not different between groups. While SPBD, SPAD, and ITD values were found similar (p > 0.05), PDA and PV were significantly different. PDA was > 45 degree in 21 cases in Group I (72.4 %) and in 7 cases in Group II (33.3 %) (p = 0.011). The mean of PV was 37.4 (20–60) cc and 49.9 (30–75) cc in Group I and Group II, respectively (p = 0.001).
Conclusions
While planning RPP operations, by selecting the prostate cancer cases with a prostate of low volume and localized deeper in the pelvis during suprapubic ultrasonography, urologists may have a chance to perform this technique more easily during the learning period. 相似文献
