OBJECTIVE To answer the question of whether the anatomical center of the subthalamic nucleus (STN), as calculated indirectly from stereotactic atlases or by direct visualization on magnetic resonance imaging (MRI), corresponds to the best functional target. Since the neighboring red nucleus (RN) is well visualized on MRI, we studied the relationships of the final target to its different borders...

in the present work, we have investigated the sorption efficiency of the treated activated carbon from walnut shell(acw) towards direct red 81 (dr81) and direct blue 71 (db71) for the removal from aqueous solution. thesorption study of acw at the solid-liquid interface was investigated using kinetic, sorption isotherms, ph effectand amount of adsorbent. experimental data were analyzed by langmu...

T cell antigen receptor (TCR) V(D)J variable region exon assembly is ordered, with D to J rearrangements occurring before joining of V s to a DJ complex. Germ-line V(D)J segments are flanked by recombination signal (RS) sequences, which consist of heptamers and nonamers separated by a spacer of 12 (12-RS) or 23 (23-RS) bp. V(D)J recombination is restricted by the 12/23 rule; joining occurs only...

12 13 The removal of fluoride using red mud has been improved by acidifying red mud with 14 hydrochloric, nitric and sulphuric acid. This investigation shows that the removal of fluoride 15 using red mud is significantly improved if red mud is initially acidified. The acidification of 16 red mud causes sodalite and cancrinite phases to dissociate, confirmed by the release of 17 sodium and alumi...

Dobrzyn, Agnieszka, Pawel Dobrzyn, Seong-Ho Lee, Makoto Miyazaki, Paul Cohen, Esra Asilmaz, D. Grahame Hardie, Jeffrey M. Friedman, and James M. Ntambi. Stearoyl-CoA desaturase-1 deficiency reduces ceramide synthesis by downregulating serine palmitoyltransferase and increasing -oxidation in skeletal muscle. Am J Physiol Endocrinol Metab 288: E599–E607, 2005. First published November 23, 2004; d...

B lymphocytes use somatic hypermutation (SHM) to optimize immunoglobulins. Although SHM can rescue single point mutations deliberately introduced into nonimmunoglobulin genes, such experiments do not show whether SHM can efficiently evolve challenging novel phenotypes requiring multiple unforeseeable mutations in nonantibody proteins. We have now iterated SHM over 23 rounds of fluorescence-acti...

Biological treatment, especially enzymatic methods, can be employed for effective and environmental- friendly treatment of dye effluents. Laccase, belonging to the blue multi-copper oxidases category, can oxidize a wide variety of substrates, especially synthetic dyes. In this study, laccase was used to biodegrade two azo dyes, i.e., Direct Red 23 and Acid Blue 92. Before conducting the exp...

for evaluation of iranian onion morphotypes potentials and application of them in breedingprogrames, seeds of 23 iranian onion morphotypeswere collected from east azarbaijan (redazarshahrmorphotypes), tehran (red rey morphotypes), razavi khorasan (red neyshaboormorphotypes) and zanjan (gholyghese morphotypes). these onion morphotypes were planted inrcbd design in four replications in seed and p...
