A Multi-Resolution Algorithm for Cytological Image Segmentation

This paper propses a multi-resolution method for cell segmentation, and outlines some of the advantages it has over other techniques. The research is based on approach developed by Wilson and Spann, and the other paper details some improvements on this algorithm for this particular problem

The effect of carbohydrate and marine peptide hydrolysate co-ingestion on endurance exercise metabolism and performance

Background: The purpose of this study was to examine the efficacy of introducing a fish protein hydrolysate (PEP) concurrently with carbohydrate (CHO) and whey protein (PRO) on endurance exercise metabolism and performance.Methods: In a randomised, double blind crossover design, 12 male volunteers completed an initial familiarisation followed by three experimental trials. The trials consisted of a 90 min cycle task corresponding to 50% of predetermined maximum power output, followed by a 5 km time trial (TT). At 15 min intervals during the 90 min cycle task, participants consumed 180 ml of CHO (67 g.hr-1 of maltodextrin), CHO-PRO (53.1 g.hr of CHO, 13.6 g.hr-1 of whey protein) or CHO-PRO-PEP (53.1 g.hr-1 of CHO, 11 g.hr-1 of whey protein and 2.4 g.hr-1of hydrolyzed marine peptides).Results and conclusions: During the 90 min cycle task, the respiratory exchange ratio (RER) in the CHO-PRO condition was significantly higher than CHO (p < 0.001) and CHO-PRO-PEP (p < 0.001). Additionally, mean heart rate for the CHO condition was significantly lower than that for CHO-PRO (p = 0.021). Time-to-complete the 5 km TT was not significantly different between conditions (m ± SD: 456 ± 16, 456 ± 18 and 455 ± 21 sec for CHO, CHO-PRO and CHO-PRO-PEP respectively, p = 0.98). Although the addition of hydrolyzed marine peptides appeared to influence metabolism during endurance exercise in the current study, it did not provide an ergogenic benefit as assessed by 5 km TT performance
