More generally, we hypothesize that it would be efficient to alter connections involving higher-order neurons that robustly represent a relevant feature of an external stimulus (e.g., the presence of a fly of the opposite sex) rather than more peripheral neurons, which can be activated by more diverse stimuli.
The YORP effect is indicated to be less efficient in altering asteroid spin rates from our results when compared with the flat distribution found by Pravec et al.
Subcutaneous delivery of rotenone, on the other hand, was reported to be more efficient in altering selectively the dopaminergic cells [22].
Because the 103+/ kasA mutant TDM is shorter than 103+ TDM, it may be less efficient at altering such membrane characteristics.
Furthermore, although the brood size manipulation experiment was efficient at altering nestling body mass, there was no evidence that this experimental manipulation of nestling early growth conditions affected the length of their telomeres.
A survey by British Car Auctions, a lobby group, this week issued a press release about a survey they had done, saying that half of respondents felt that at some point rising fuel prices would "force" them to change to a more efficient car or alter their driving habits.
Stable expression of glycosyltransferases and transport signal chimeras has been demonstrated to represent an efficient tool to alter cell- and species-specific glycosylation (Grabenhorst and Conradt, 1999. J. Biol. Chem. 274, 36107 36116).
Site-directed mutagenesis is an efficient method to alter the structure and function of genes.
In patients with COPD, hypoxic pulmonary vasoconstriction is the most efficient way to alter the Va/Q ratios to improve gas exchange.
Many studies emphasized that Th2 cytokines could alter efficient Th1 antiviral immune response and lead to the development of more severe disease, but we have observed a higher IL-4 production in infants with lower respiratory tract infection [ 19].
