In order to assess their photostability an HPLC method was developed and validated for linearity, accuracy and precision, selectivity, limit of detection and quantitation and ruggedness. Preliminary solution photostudies under controlled light conditions (UV, sunlight, fluorescent light) indicated that the rate of degradation followed first-order kinetics with perphenazine the most susceptible to.photodegradation under all light conditions studied. In vitro and in vivo metabolism yielding the 5-sulphoxide and its reported presence on decomposition of the phenothiazines25 led to the development of a synthetic procedure suitable for the sutphoxides of all four derivatives based on the method proposed by Owens et al. in order to provide standards for comparison in the photostudies⁷. Since ICH regulations require that impurities> 0.1 % are examined and identified⁷⁴ and semi-preparative isolation of photoproducts proved unsuccessful, LC-MS having been well documented for structural.elucidation⁷⁵ ⁷⁵ ⁷⁶ ⁷⁷ was used to characterize solution (UV, sunlight, fluorescent light) and preliminary solid (UV) photostudies. The chloroderivatives underwent dechlorination and sulphoxidation with subsequent photosubstitution in the case of prochlorperazine to yield the 2-hydroxy derivative and sulphoxidation of the dechloro-derivative of perphenazine. The sulphoxides of both trifluoperazine and fluphenazine were formed with further oxidation to the respective sulphones occurring. Preliminary solid state (UV) photostudies showed fluphenazine to be the least stable with 30.71 % degradation as opposed to 7.57% for prochlorperazine, 4.28% for perphenazine and 7.10% for trifluoperazine witn sulphoxidation observed to be. the major degradation pathway. Since in vitro metabolism of perazine derivatives is reported to occur via N-oxidation, N-demethylation, sulphoxidation and aromatic hydroxylation¹⁸ it does appear that there is some correlation between metabolic and photoproducts. However the fact that solution (UV) photostudies indicates trifluoperazine to be the most and perphenazine the least stable does not concur with the proposed order of pharmacological activity.]]> Wed 12 May 2021 16:36:16 SAST ]]> Metabolic responses in melanoma cells to combined nutrient supplementation https://vital.seals.ac.za/vital/access/manager/Repository/vital:4036 Wed 12 May 2021 16:13:35 SAST ]]> Learning from the people : participatory rural appraisal, geography and rural development in the 'new' South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:6675 Wed 12 May 2021 16:05:05 SAST ]]> Biologically active natural products from South African marine invertebrates https://vital.seals.ac.za/vital/access/manager/Repository/vital:3761 Wed 12 May 2021 15:53:48 SAST ]]> Environmental education : a strategy for primary teacher education https://vital.seals.ac.za/vital/access/manager/Repository/vital:1512 Wed 12 May 2021 15:50:07 SAST ]]> Cytogenetic studies of Pseudobarbus and selected Barbus (Pisces: Cyprinidae) of southern Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:5252 Wed 12 May 2021 15:44:24 SAST ]]> LRA Trainers Course https://vital.seals.ac.za/vital/access/manager/Repository/vital:42661 Wed 12 May 2021 14:36:53 SAST ]]> Debate on globalisation https://vital.seals.ac.za/vital/access/manager/Repository/vital:42156 Wed 12 May 2021 14:12:40 SAST ]]> Globlisation, structural adjustmentand education https://vital.seals.ac.za/vital/access/manager/Repository/vital:42960 Wed 12 May 2021 13:56:12 SAST ]]> Management education and training https://vital.seals.ac.za/vital/access/manager/Repository/vital:54490 Wed 10 Aug 2022 12:53:19 SAST ]]> Die ontwikkeling van 'n plattelandse tak van die ACVV 1900-1996 https://vital.seals.ac.za/vital/access/manager/Repository/vital:694 Wed 10 Aug 2022 06:00:16 SAST ]]> A phenomenological investigation into educational leaders' perceptions of themselves, their followers, and their organisational contexts https://vital.seals.ac.za/vital/access/manager/Repository/vital:1697 Wed 05 Apr 2023 08:16:17 SAST ]]> Maguqela lendawo https://vital.seals.ac.za/vital/access/manager/Repository/vital:63024 Tue 28 Mar 2023 13:14:08 SAST ]]> Maguqela lendawo https://vital.seals.ac.za/vital/access/manager/Repository/vital:63025 Tue 28 Mar 2023 13:14:06 SAST ]]> Kuyasetyenzwa https://vital.seals.ac.za/vital/access/manager/Repository/vital:63019 Tue 28 Mar 2023 13:07:07 SAST ]]> Ndemka https://vital.seals.ac.za/vital/access/manager/Repository/vital:63023 Tue 28 Mar 2023 13:06:53 SAST ]]> Ahomna https://vital.seals.ac.za/vital/access/manager/Repository/vital:63018 Tue 28 Mar 2023 13:00:12 SAST ]]> Belethe https://vital.seals.ac.za/vital/access/manager/Repository/vital:63015 Tue 28 Mar 2023 12:59:58 SAST ]]> Ndinothixo omkhulu https://vital.seals.ac.za/vital/access/manager/Repository/vital:62968 Tue 28 Mar 2023 09:43:52 SAST ]]> Belethe https://vital.seals.ac.za/vital/access/manager/Repository/vital:63340 Tue 11 Apr 2023 10:12:07 SAST ]]> Bayeza kusasa https://vital.seals.ac.za/vital/access/manager/Repository/vital:63341 Tue 11 Apr 2023 10:05:15 SAST ]]> Icamagu livumile https://vital.seals.ac.za/vital/access/manager/Repository/vital:63337 Tue 11 Apr 2023 09:58:09 SAST ]]> Ahomna https://vital.seals.ac.za/vital/access/manager/Repository/vital:63334 Tue 11 Apr 2023 09:51:19 SAST ]]> Cengeletshani https://vital.seals.ac.za/vital/access/manager/Repository/vital:63332 Tue 11 Apr 2023 09:44:07 SAST ]]> Icamagu livumile https://vital.seals.ac.za/vital/access/manager/Repository/vital:63330 Tue 11 Apr 2023 09:37:08 SAST ]]> First-row transition metal phthalocyanines as catalysts for water electrolysis https://vital.seals.ac.za/vital/access/manager/Repository/vital:57081 Thu 29 Sep 2022 22:21:11 SAST ]]> Metallophthalocyanine catalysed electroreduction of nitrate and nitrite ions in alkaline media https://vital.seals.ac.za/vital/access/manager/Repository/vital:57073 5 μg ml−1) are determined by adsorptive cathodic stripping voltammetry (AdCSV) on a mercury film glassy carbon electrode, using catechol, 4-methylcatechol, 4-t-butylcatechol and resorcinol as complexing ligands.

However, these components differ in their affinities for metal ions. Storage of metal ions within the cell occurs predominantly in the vacuole. The present study concluded that metal accumulation by the vacuole could be related to size. Metal accumulation occurred in the order of Cu2+ > Co2+ > Cd2+ with a corresponding decrease in atomic radii of Cd2+ > C02+ > Cu2+. Vacuolar ion deposition occurs at an early stage during the internalization of metal ions within the yeast cells. At the onset of vacuolar saturation, depositions of metal ions as granules within the cytosol occurs. In the presence of heavy metal cations viable yeast cells can be shown to exhibit two types of cellular responses. Uptake of Cu2+ and Cd2+ causes the loss of intracellular physiological cations from within the yeast cell. In comparison, uptake of Co2+ into the cell does not have this effect. All three heavy metal cations initiate plasma cell membrane permeability, thus the Cu2+ and Cd2+ induced loss of the intracellular cations, occurs. ~ a result of ion-exchange mechanisms and not due to cation leakage brought about by membrane permeabilization. Uptake of heavy metals by viable yeasts appears to be generally non-selective though the amount of metals accumulated are largely affected by the ratio of ambient metal concentration to biomass quantity. In addition, the energy dependent nature of internalization necessitates the availability of an external energy source for metal uptake by viable yeast cells. For these reasons metal removal from industrial waste water was investigated using non-viable biomass. By immobilizing the yeast cells additional mechanical integrity and stability was conferred apon the biomass. The three types of biomass preparations developed in this study, viz. polyvinyl alcohol (PV A) Na-alginate, PV A Na-orthophosphate and alkali treated polyethylenimine (PEI):glutaraldehyde (GA) biomass pellets, all fulfilled the necessary physical requirements. However, the superior metal accumulating properties of the PEI:GA biomass determined its selection as a biosorbent for bioremediation purposes. Biosorption of heavy metals by PEI:GA biomass is of a competitive nature, with the amount of metal accumulated influenced by the availability of the metal ions. This availability is largely determined by the solution pH. At low pH values the affinity of the biomass for metals decreases, whilst enhanced metal biosorption occurs at higher pHs, ego pH 4.5 - 6.0. PEI:GA biomass pellets can be implemented -as a biosorbent for the bi9remediaiton of high concentration, low-volume metal containing industrial waste. Several options regarding the bioremediation system are available. Depending on the concentration of the metals in the effluent, the bioremediation process can either be used independently or as part of a biphasic remediation system for the treatment of waste water. Initial phase chemical modification may be required, whilst two types of biological systems can be implemented as 'part of the second phase. The PEI:GA biomass can either be contained within continuous-flow fixed bed tanks or continuous-flow stirred bioreactor tanks. Due to the simplicity of the process and the ease with which scale-up is facilitated, the second type of system shows greater application potential for the treatment of this type of industrial waste water than the fixed-bed systems.]]> Thu 13 May 2021 02:58:09 SAST ]]> A comparative study of the Grey-headed Sparrow (Passer griseus L) and the House Sparrow (Passer domesticus L) in Malawi https://vital.seals.ac.za/vital/access/manager/Repository/vital:5654 Thu 13 May 2021 02:32:42 SAST ]]> A case study of English/Xhosa code switching as a communicative and learning resource in an English medium classroom https://vital.seals.ac.za/vital/access/manager/Repository/vital:1436 Thu 13 May 2021 02:32:21 SAST ]]> A revised checklist of the epipelagic and shore fishes of the Chagos Archipelago, central Indian Ocean https://vital.seals.ac.za/vital/access/manager/Repository/vital:15031 Thu 13 May 2021 01:50:10 SAST ]]> Newsletter of the Self-Employed Womens Union - No.22 https://vital.seals.ac.za/vital/access/manager/Repository/vital:39855 Thu 13 May 2021 01:44:18 SAST ]]> Effects of sustained elevated CO₂ concentration on two cultivars of barley (Hordeum vulgare L.) https://vital.seals.ac.za/vital/access/manager/Repository/vital:4226 Thu 13 May 2021 01:32:39 SAST ]]> Eco-ethology of shell-dwelling cichlids in Lake Tanganyika https://vital.seals.ac.za/vital/access/manager/Repository/vital:5265 Thu 13 May 2021 01:13:19 SAST ]]> Application of capillary electrophoresis for the assay of erythromycin and its related substance https://vital.seals.ac.za/vital/access/manager/Repository/vital:3765 Thu 13 May 2021 00:59:57 SAST ]]> An evaluation of small scale open cast mining of UG2 in the Bushveld complex https://vital.seals.ac.za/vital/access/manager/Repository/vital:4943 Thu 13 May 2021 00:25:05 SAST ]]> An investigation into the effects of inorganic toxins and tryptophan metabolites on the forebrain cholinergic system and the pineal gland of the rat https://vital.seals.ac.za/vital/access/manager/Repository/vital:4018 Thu 13 May 2021 00:24:29 SAST ]]> An investigation into patterns of interaction in small teaching groups at Rhodes University, with particular emphasis on the effect of gender, mother-tongue and educational background https://vital.seals.ac.za/vital/access/manager/Repository/vital:2350 Thu 13 May 2021 00:18:41 SAST ]]> Exploitation of the bait organism Upogebia africana (Crustacea: Anomura) in the Knysna estuary https://vital.seals.ac.za/vital/access/manager/Repository/vital:5691 Thu 13 May 2021 00:02:46 SAST ]]> Comparative ultrastructure of plasmodesmata of Chara and selected bryophytes: towards an elucidation of the evolutionary origin of plant plasmodesmata https://vital.seals.ac.za/vital/access/manager/Repository/vital:6506 Thu 11 Aug 2022 07:09:04 SAST ]]> Maguqela lendawo https://vital.seals.ac.za/vital/access/manager/Repository/vital:62956 Mon 27 Mar 2023 16:23:33 SAST ]]> Izani Marhanuga https://vital.seals.ac.za/vital/access/manager/Repository/vital:62941 Mon 27 Mar 2023 12:46:16 SAST ]]> Himani ngoku https://vital.seals.ac.za/vital/access/manager/Repository/vital:62939 Mon 27 Mar 2023 12:32:27 SAST ]]> Homna Homna https://vital.seals.ac.za/vital/access/manager/Repository/vital:62938 Mon 27 Mar 2023 12:25:09 SAST ]]> Belethe https://vital.seals.ac.za/vital/access/manager/Repository/vital:62932 Mon 27 Mar 2023 12:04:17 SAST ]]>
