Fine structure in the α decay of 223U

Fine structure in the α decay of 223U was observed in the fusion-evaporation reaction 187Re(40Ar, p3n) by using fast digital pulse processing technique. Two α-decay branches of 223U feeding the ground state and 244 keV excited state of 219Th were identified by establishing the decay chain 223U →α1 219Th →α2 215Ra →α3 211Rn. The α-particle energy for the ground-state to ground-state transition of 223U was determined to be 8993(17) keV, 213 keV higher than the previous value, the half-life was updated to be 62−10+14 μs. Evolution of nuclear structure for N = 131 even-Z isotones from Po to U was discussed in the frameworks of nuclear mass and reduced α-decay width, a weakening octupole deformation in the ground state of 223U relative to its lighter isotones 219Ra and 221Th was suggested

Results of anastomosis of accessory lower polar graft artery to internal iliac artery in renal transplantation

Background: Our objective is to perform a renal graft transplant using multiple arteries where the lower polar artery will indeed be anastomosed to the internal iliac artery end to side following declamping the main arterial supply in terms of ischemia time, diuresis, graft perfusion,  and postoperative clinical parameters and investigations. Methods: Fifty live donors underwent vascular anastomosis of the graft auxiliary lower polar artery to recipient internal iliac artery end to side anastomosis with various renal arteries bilaterally, including lower polar artery in chosen kidney. The recipients' intraoperative warm and total ischemia periods, as well as their postoperative incidence of acute tubular necrosis, were assessed (ATN). Diuresis, urinary output, and creatinine levels at 1, 3, and 5 days after surgery, as well as at 2 months afterwards. MRI and Doppler ultrasonography, if necessary. Results: In contrast to warm, the mean total ischemia time was 20.86 minutes. Low incidence of ATN (8%) was controlled and postoperative recovery went without a hitch. Regarding postoperative urine output and serum creatinine level monitoring, clinical and laboratory indicators were satisfactory. Depending on the assessment method, colour Doppler ultrasonography reveals well perfused transplanted grafts with a satisfactory peak systolic velocity ratio in the auxiliary graft artery
