Spontaneous cortical activity transiently organises into frequency specific phase-coupling networks
Nature Communications, 2018 Coordination of neural activity between distant brain areas is necessary for cognition. Here, the authors report using MEG that various brain networks show dynamic phase coupling through specific frequency bands in the alpha and delta/theta range ...

The role of stride frequency for walk-to-run transition in humans
Scientific Reports, 2017 It remains unclear why humans spontaneously shift from walking to running at a certain point during locomotion at gradually increasing velocity. We show that a calculated walk-to-run transition stride frequency (70.6 ± 3.2 strides min−1) agrees with a ...

Activation of human pepsinogens
FEBS Letters, 1988 Human pepsinogen A3 and A5 have been purified to chromatographic and electrophoretic homogeneity. At pH 2 pepsinogen A3 activates at a much faster rate than pepsinogen A5. Leu‐23 — Lys‐24 is the first bond cleaved during activation of pepsinogen A3. This bond is also cleaved in pepsinogen A5, but together with the cleavage of Asp‐25 — Phe‐26.
