(Wiley, 2020)CaMK2N1 and CaMK2N2 (also known as CaMKIIN alpha and beta) are endogenous inhibitors of calcium/calmodulin-dependent kinase II (CaMKII), an enzyme critical for memory and long-term potentiation (LTP), a form of synaptic ...
-
(BioMed Central, 2013)CaMKII is a major synaptic protein that is activated during the induction of long-term potentiation (LTP) by the Ca2+ influx through NMDARs. This activation is required for LTP induction, but the role of the kinase in the ...

(IOP Publishing, 2013)The Lagrangian equations of motion for massive spinning test particles (tops) moving on a gravitational background using general relativity are presented. The paths followed by tops are nongeodesic.An exact solution for ...
-
(SPRINGER, 2010-10)Despite the increasing claims that structural complexity in agroforestry plantations is a key variable for enhancing bird biodiversity, few studies have experimentally manipulated the understory component of structural ...

(BMC, 2018)Background: Parasites can exert selection pressure on their hosts through effects on survival, on reproductive success, on sexually selected ornament, with important ecological and evolutionary consequences, such as changes ...
-
(Sage, 2015)We set out to test the ability to detect vegetation change from organic soil nutrient (carbon and nitrogen) composition in the fire-determined forest/ non-forest mosaic of western Tasmania, Australia. We find no relationship ...
