Initiation of DNA replication in eukaryotes, archea, and eubacteria requires interaction of structurally conserved ATP-binding initiator proteins and origin DNA to mediate assembly of replisomes. However, the specific requirement for ATP in the early steps of initiation remains unclear. This is true even for the well studied Escherichia coli replication origin, oriC, where the ATP form of initi...

The feeding behavior of the marine mollusc Aplysia californica is an intensively studied model system for understanding the neural control of behavior. Feeding movements are generated by contractions of the muscles of the buccal mass. These muscles are internal and cannot be visualized during behavior. In order to infer the movements of the muscles of the buccal mass, two kinematic models were ...

SRIF activates an inwardly rectifying K+ current in human GH-secreting adenoma cells. Activation of this K+ current induces hyperpolarization of the membrane and abolishment of action potential firing. This mechanism is an essential mechanism for SRIF-induced decrease in intracellular Ca2+ concentration and inhibition of GH secretion. The activation of the inwardly rectifying K+ current is medi...

The dynamic motion of ions in electrolyte solutions and its effect on recombination was investigated by the heterodyne transient grating method in addition to transient absorption and transient photocurrent methods in dye sensitized solar cells. Realignment of ionic species at the electrode/electrolyte interface was observed after the electron injection in TiO2 on the order of μs. The process w...

Background & AimsThe Rutgeerts’ scoring system is used to evaluate patients with Crohn’s disease (CD) following ileocolic resection, based on endoscopic findings at the anastomosis and in neoterminal ileum. We investigated rates of clinical surgical recurrence CD after surgery effect therapy modification post-operative findings.MethodsWe collected data from 365 adults (20% score i0, 10% i1, 49%...
