The Journal of Physiology, 2006 In this issue of The Journal of Physiology, Uebachs et al. (2006) report a seemingly simple observation: the rate of recovery from inactivation of CaV3 (T-type) calcium channels depends on the length of the depolarization that produced the inactivation. Why is this heretical? A basic principle of chemical kinetics is that rate constants are constant.

Rate constants for diffusive processes by partial path sampling
, 2003 We introduce a path sampling method for the computation of rate constants for systems with a highly diffusive character. Based on the recently developed algorithm of transition interface sampling (TIS) this procedure increases the efficiency by sampling ...

Vibrational deactivation on chemically reactive potential surfaces: An exact quantum study of a low barrier collinear model of H + FH, D + FD, H + FD and D + FH [PDF]
, 1980 We study vibrational deactivation processes on chemically reactive potential energy surfaces by examining accurate quantum mechanical transition probabilities and rate constants for the collinear H + FH(v), D + FD(v), H + FD(v), and D + FH(v) reactions ...

On the existence of Hopf bifurcations in the sequential and distributive double phosphorylation cycle [PDF]
, 2019 Protein phosphorylation cycles are important mechanisms of the post translational modification of a protein and as such an integral part of intracellular signaling and control. We consider the sequential phosphorylation and dephosphorylation of a protein

Universal rate constants for reactive collisions of ultracold molecules
, 2010 A simple quantum defect model gives analytic expressions for the complex scattering length and threshold collision rates of ultracold molecules. If the probability of reaction in the short-range part of the collision is high, the model gives universal ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.

Thermokinetic study on the inactivation reactions of 1-methylphthalazinium ylids [PDF]
Journal of the Serbian Chemical Society, 2003 The present paper consists in a thermokinetic study on the dimerization reactions of 1-methylphthalazinium ylids with NO2 (ylid 1) and, respectively, OCH3 (ylid 2) substituents in the p position of the benzoyl radical bound to the ylidic carbanion ...
