In this muscle, as the denervation time elapses owing to the decrease of contractive structures and alterations in the number of membranous organelles, there is a reduction in myosin and actine syntheses, which in turn results in a decrease in the size of fibers and resorption of myofibrils (Tischeler et al., 1990; Weis et al., 2000; Borisov et al., 2001; Washabaugh et al.
By the participation of proteins such as Bcl-2 and Bcl-XL, with an increase in the caspase-9 expression which begins the proteolitic cascade, thus activating the caspase-7 effector, leading to the loss of denervated muscular fibers (Tews et al., 2005), the denervation process might provoke an intrinsic 'suicide' program (Tang et al.).
In panoramic observation, it was observed that in the normal group, there is a regularity as for the size and disposition of the fibers and this regularity is lost as the denervation period increases.
The finding that both denervated and splinted crayfish turned toward their unaltered side suggests that the response was not some artifact due to the artificial removal of sensory information from the denervation procedure, but rather that they were comparing inputs from both antennae.
It remains to be determined whether the effect of denervation is temporary or persists until the crayfish grows a new antenna.
After a 30-min stabilization period, a subprotocol was performed to evaluate the effectiveness of aortic denervation. This consisted of recording MAP and HR for 1 min before (control) and 4 min after administering three 100-[micro]L boluses of phenylephrine at 10-min intervals [PHE; 10 [micro]g/kg iv; P-6126, Sigma-Aldrich Quimica (S-AQ), Mexico] and three 100-[micro]L boluses of sodium nitroprusside at 6-min intervals (SNP; 5 [micro]g/kg iv; S-0501, S-AQ).
TGSI ranges previously established (16) were as follows: for sham barodenervation, 10.09 to 11.46; for aortic denervation, 8.40 to 9.94, and for sino-aortic denervation, 7.68 to 8.24.
MAP data in S-I were first analyzed (95%CI) by linear mixed-effects models (19) to evaluate the denervation * diet interaction and by ANCOVA to evaluate the effects of pdMAP and group on LNaMAP.
In addition to the clinical efficacy that renal denervation so far has shown, it is relatively simple and easy to do and fairly quick; the procedure involves modestly priced equipment and appears very safe as well, noted Dr.
