Methods: The clinical and preoperative imaging data of 79 patients with renal tumors who underwent surgical treatment in our hospital from June 2020 to January 2024 were collected. According to the results of preoperative renal CT three-dimensional reconstruction, the relationship between vascular variation and renal warm ischemia time, total operation time, intraoperative bleeding and postoperative complications was analyzed, and R.E.N.A.L. score was performed. Logistic regression was used to screen out independent risk factors for renal warm ischemia time greater than 20 min. Results: There was no significant difference in renal warm ischemia time, total operation time, intraoperative blood loss and postoperative complications between the presence or absence of vascular variation (P > 0.05). The total R.E.N.A.L. score was an independent risk factor for renal warm ischemia time greater than 20 min (P P < 0.05). Conclusion: CT three-dimensional reconstruction can clearly understand the anatomical location of the kidney, tumor and blood vessels before surgery, thereby reducing the occurrence of perioperative complications.展开更多

The aim of the current manuscript was to assess the impact of different timings for fungicide application (epoxiconazole + pyraclostrobin) on the control of leaf rust (Puccinia triticina E.) and yellow spot (Pyrenophora tritici-repentis) diseases in two wheat genotypes featured by distinct levels of susceptibility in Southern Brazil.

The following treatments were imposed in the current study: control (with no sprays);sprays at the first node, booting and heading;sprays at stem extension and flowering;sprays at booting and heading. Throughout the entire crop growing season, the control treatment was conducive to the highest severity levels for both diseases. The increasing of the area under the diseases progress curve assessed herein substantially impinged upon yield components of both wheat genotypes under scrutiny.
