A 6-month maintenance schedule of mitomycin C after radical nephroureterectomy for upper tract urothelial carcinoma for the prevention of intravesical recurrence: a retrospective, single center study.

Purpose: To show the effect of a 6-month (4 times weekly followed by 5 times monthly) maintenance mitomycin C regimen on the prevention of intravesical recurrence (IVR) after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC).

Methods: A total of 119 patients undergoing a RNU between 2007 and 2021 in a single center hospital were retrospectively reviewed. A total of 66 patients were eligible for further analysis.

The role of frequency information and teleological reasoning in infants' and adults' action prediction.

This study investigates the contribution of frequency learning and teleological reasoning to action prediction in 9-month-old infants and adults. Participants observed how an agent repeatedly walked to a goal while taking the longer of 2 possible paths, as the shorter and more efficient path was impassable. In the subsequent test phase, both paths were passable.

Hydrogen peroxide as an electron acceptor for mitochondrial respiration in the yeast Hansenula polymorpha.

Chemostat cultures of a catalase-negative mutant of Hansenula polymorpha CBS 4732 were able to decompose hydrogen peroxide at a high rate. This was apparent from experiments in which the yeast was grown under carbon limitation in chemostat culture on mixtures of glucose and H2O2. The enzyme responsible for H2O2 degradation is probably the mitochondrial enzyme cytochrome c peroxidase (CCP), which was present at very high activities.

A modified hemagglutination inhibition test for estimating human follicle-stimulating hormone (hFSH) in unprocessed urine.

The development of a hemagglutination inhibition test for urinary human follicle stimulating hormone (hFSHu) is described. Antisera were raised in rabbits and absorbed immunochromatographically with crude preparations of human chorionic gonadotrophin (hCG). hFSHu was coupled to erythrocytes by means of bis-diazobenzidine.
