Abstract

This manuscript has been reproduced from the microrilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis arxJ dissertation copies are in typewriter face, while others may t>e from any type of computer printer. The quality off this rBproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event tfiat the author dkl not serid UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overiaps. Photographs included in the original manuscript have been reproduced xerographically in this copy. Higher quality 6' x 9' black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directly to order.

Normalization of doxorubicin release from graphene oxide: New approach for optimization of effective parameters on drug loading

“…Other parameters, which can influence the loading of DOX on GO, are the initial concentration of DOX and the contact time of DOX with GO. The more primary concentration of DOX leads to more loading on GO in a linear pattern [10,[17][18][19][20][21]. Nevertheless, Wu et al indicated that DOX dosage greater than 0.5 g/L leads to less loading of DOX on GO because of DOX accumulation and a decrease in the number of active sites.…”

1-Aminocyclopropane-1-Carboxylate Synthase, an Enzyme of Ethylene Biosynthesis

“…Probably, the shared active sites formed between the heterodimeric subunits of the same branch are structurally similar to those of the corresponding homodimers. All of them are characterized by seven conservative regions denoted in Figure 1 as R1-R7, which comprise the following residues (according to LE-ACS2): R1 (49)(50)(51)(52)(53)(54)(55)(56)(57)(58), R2 (89)(90)(91)(92)(93)(94)(95)(96)(97), R3 (136)(137)(138)(139)(140)(141)(142), R4 (205)(206)(207)(208)(209)(210)(211)(212)(213), R5 (274-288), R6 (304-311), and R7 (407-417). 51 The inactivity of certain heterodimers is probably due to structural restraint(s) that prevents the shared active sites to be functional.…”

“…An exception to this rule is ACS7, which is able to form functional heterodimers with some members of both branches. 26,28,29,33,45,46,48,51,[56][57][58][59] The localization of these residues is illustrated in Figure 1 and all of them are numbered according to LE-ACS2 (in parentheses the equivalent amino acid residue in Md-ACS1) and are characterized as follows: If indeed ACS heterodimers are formed in plants, they could provide an additional regulatory element in ethylene production.…”

Separation and determination of four active components in medicinal preparations by flow injection-capillary electrophoresis

“…High performance liquid chromatography (HPLC) is one of the most useful techniques for the quantification of some of the four compounds [2][3][4][5][6][7], but the use of HPLC is restricted by long analysis times, peak asymmetry and poor efficiency [6,7]. Proton nuclear magnetic resonance (NMR) [8] and gas liquid chromatography [9] have also been reported for the determination some of these analytes.…”
