Abstract:
A simple yet sensitive fluorescent sensor was reported for amitrole analysis based on integration of gold nanoparticles (AuNPs) and CdTe quantum dots (CdTe QDs) via inner filter effect (IFE). The fluorescence of GSH-coated CdTe QDs can be significantly quenched by AuNPs, and gradually restored in the presence of amitrole. Addition of amitrole induced AuNPs aggregation and decreased their characteristic surface plasmon absorption, which diminished the IFE between them. The sensor platform realized high sensitivity and good reproducibility in low concentration amitrole ranging from 9.5[Formula: see text]nM to 1000[Formula: see text]nM with a detection limit down to 4.75[Formula: see text]nM under the optimized conditions. It also resisted a wide range of interfering counterparts and showed analytical performance comparable to the majority of analytical methods reported in prior studies. We envisioned the first fluorescent amitrole sensor would be potentially useful for low cost on-site amitrole monitoring in real application.

Abstract:
A doseresponse experiment was conducted on a previously confirmed glyphosate resistant perennial ryegrass (Lolium perenne) population from a Marlborough vineyard to examine if it is also resistant to amitrole after an initial experiment suggested amitrole is less effective on this population The plants of two populations of perennial ryegrass Population O (glyphosate resistant) and Population SP (glyphosate susceptible) were multiplied up by splitting out tillers and planting them into pots The plants were sprayed with rates of amitrole from 0 to 9600 g ai/ha and each treatment consisted of five replicates (one plant per replicate) The dry weight of plant material was measured 8 weeks after herbicide application The data were fitted to a three parameter logistic model and the herbicide rate giving 50 reduction in growth (GR50) was calculated The GR50 value of Population SP for amitrole was 523 g ai/ha whereas the GR50 for Population O was found to be 131 times greater This is the first confirmed case of amitrole resistance evolving within New Zealand and further work is currently underway to study this resistance

Abstract:
Abstract Mature fruits from apple trees contain residual amounts of radiolabel derived from soil-ap- plied [3,5-14C]amitrole. This report deals with characterization of the soluble part of this radioactivity. By GC/MS of suitable derivatives 3-(1,2,4-triazol-1-yl)-2-aminopropionic acid was identified as a new metabolite of amitrole. Significant parts of radiolabel were incorporated into genuine plant products, indicating liberation of 14CO2 from the applied substance followed by reassimilation. Possible pathways of metabolism of amitrole within the system soil/apple tree are discussed.

Abstract:
Sim-type carnation flowers (Dianthus caryophyllus L., cv. Elliot's White) continuously treated with 50 mM or 100 mM 3-amino-1,2,4-triazole (amitrole) and held in the dark at 18°C did not exhibit a respiratory climacteric relative to dH2O-treated controls. No morphological changes symptomatic of floral senescence appeared in treated flowers until 12-15 days post-harvest. Other triazoles were not effective in prolonging senescence. Amitrole appears to inhibit ethylene biosynthesis by blocking the enzyme-mediated conversion of S-adenosyl-L-methionine to 1-aminocyclopropane-1-carboxylate. Ethylene action appears to be progressively inhibited in that flowers held in treatment solution for 2 d or less responded to application of 10 uL/L exogenous ethylene whereas flowers held 10 d or longer exhibited no response. Electrophoretic resolution of total crude extracts evidenced protein synthesis as well as degradation. Western analysis and total activity assays showed an amitrole concentration-specific inhibition of catalase activity.

Abstract:
Numerous factors must be considered when analyzing growth in a cultured cell system. One extremely critical factor is the initial cell mass. The effect of initial mass (10 to 400 mg) on growth rate was assessed for cell lines tolerant and susceptible to the herbicides 3-amino-1,2,4-triazole (amitrole) and N-(phosphonomethyl)glycine (glyphosate). For a given cell line, the relationship between initial mass and growth rate was comparable in the presence and absence of the growth inhibitors. However, among cell lines the response varied. For one amitrole- and glyphosate-tolerant cell line, increased initial callus mass resulted in an increased relative rate of growth. However, the opposite effect was observed for another cell line which was also tolerant to both herbicides. For a third cell line which was herbicide sensitive no initial mass effect was observed. A fourth cell line (amitrole tolerant – glyphosate sensitive) also showed no initial mass effect except for the very small 10-mg calluses, which had significantly lower growth rates. The observed effect of initial mass was dependent on the method of calculating growth rates.

Abstract:
La nappe phreatique est une ressource importante d'eau de consommation humaine, mais des risques de pollution la menacent. Dans ce travail nous avons realise une premiere approche de ce risque pour 3 pesticides de la famille des triazoles ; le flusilazole, le flutriafol et l'amitrole. Dans un premier temps, nous avons etabli les methodes d'analyses et les techniques d'extraction de ces 3 composes a partir de l'eau et de la terre, celles-ci etant indispensables a l'etude de leur transfert. L'amitrole est determine par des protocoles analytiques differents de ceux mis au point pour le flusilazole et le flutriafol. Dans un deuxieme temps, l'evaluation du transfert a ete effectuee par l'intermediaire de colonnes de terre et d'etudes d'adsorption des pesticides sur la terre. Les resultats ont montre que le comportement dans le sol de ces 3 pesticides de la meme famille n'est pas identique. Toutefois nous avons pu conclure que le risque de contamination directe de la nappe phreatique par ces composes est faible, voire negligeable

Abstract:
Dans le but d'obtenir des composés originaux ayant une activité inhibitrice envers la NE, des triazoles et des 2-aminofuranes diversement substitués ont été synthétisés. Une réaction de "click chemistry" catalysée par le cuivre entre un azide et un alcyne a été appliquée pour la synthèse des triazoles. La synthèse des composés de type 2-aminofuranes est basée sur l'attaque nucléophile d'un isonitrile sur un γ-oxo butynoate d'alkyle en présence d'un aldéhyde aromatique.Les tests biologiques ont été réalisés tout au long de la thèse. Les composés présentant les meilleures IC50 envers la NE ont été sélectionnées pour une évaluation en terme de sélectivité vs les autres sérines protéases du PN (la cathepsine G et la protéinase 3). Enfin, les meilleurs inhibiteurs ont subi une évaluation de leur activité anti-oxydante selon deux méthodes: méthode au DPPH (1,1-diphényl-2-picryl-hydrazyl) et méthode au thiocyanate ferrique
To prepare new compounds with an inhibitory activity towards NE, diversely substituted triazoles and 2-aminofuranes were synthesized. Triazoles were obtained using the copper catalyzed "click chemistry" between an azide and an alkyne. The synthesis of 2-aminofuranes is based on the nucleophilic attack of an isonitrile on an alkyl γ-oxo-butynoate in the presence of an aromatic aldehyde.Biological assays were carried out throughout the thesis. Compounds owning the best IC50 towards NE were selected for evaluation in terms of selectivity vs the two other serine-proteases of the PN (cathepsin G and proteinase 3).

Abstract:
Reduction of populations of the B strain (poinsettia) of sweetpotato whitefly (SPWF), Bemisia tabaci Gennadius, resulted from applications of buprofezin or amitraz to cotton in central Arizona (Maricopa, AZ). Control was fair to good control for this insect. However, yields of seed cotton in treated plots were not increased significantly compared to untreated plots, following three applications of these insecticides during the season. Similar results on percentage sugar on lint and lint stickiness from honeydew of SPWF in both treated and untreated plots were obtained.

Abstract:
This paper describes the construction of a carbon paste electrode (CPE) impregnated with nanoparticles of iron(II) phthalocyanine (nanoFePc). The new electrode (nanoFePc-CPE) revealed interesting electrocatalytic behaviour towards amitrole; pure catalytic diffusion-controlled process, with high Tafel slope (235 mV/decade) suggesting strong binding of amitrole with nanoFePc catalyst. The effects of catalyst loading, varying pH and electrolytes were studied. The mechanism for the interaction of amitrole with the nanoFePc is proposed to involve the Fe[superscript (III)]Pc/Fe[superscript (II)]Pc redox process. Using chronoamperometry (E = +0.42 V versus Ag/AgCl) technique, the sensor was reliably employed for amitrole assay at pH 12.0 phosphate buffer (with sodium sulphate as the supporting electrolyte) for up to 12 nM amitrole with excellent sensitivity (ca. 3.44 μA/nM) and low detection limit (3.62 ± 0.11 nM, i.e. 0.305 μg L[superscript (−1)] using the YB + 3σB criterion and 0.85 ± 0.03 nM, i.e. 70 ng/L with the Y[subscript B] + 2[subscript σB] criterion) as well as satisfactory amperometric selectivity coefficient (K[subscript amp] ≈ 7.4 × 10[superscript (−4)] for ammonium thiocyanate, a component of many amitrole herbicides, and 3.2 × 10[superscript (−3)] for asulam pesticide). The surface of the electrode can easily be regenerated by simple polishing on an alumina paper, obtaining a fresh surface ready for use in a new assay. The proposed electrode was successfully applied in the quantification of amitrole in its commercial formulation as well as in tap water samples.

Abstract:
Dissertação de Mestrado Integrado em Medicina Veterinária
A demodicose canina é uma doença cutânea inflamatória provocada pela proliferação excessiva de ácaros do género Demodex, um comensal da pele dos canídeos domésticos. O principal agente etiológico é Demodex canis, contudo foram recentemente identificadas duas outras espécies, D. injai e D. cornei. Esta doença apresenta uma forte componente genética e imunológica e afeta, sobretudo, animais jovens. Estão descritas diferentes apresentações da demodicose, as quais vão influenciar a abordagem diagnóstica e terapêutica. Com o desenvolvimento de novos antiparasitários, as percentagens de cura são elevadas, no entanto, é frequente ocorrerem recidivas. O tratamento baseia-se na aplicação de banhos semanais com amitraz, normalmente associada à administração de uma lactona macrocíclica. Independentemente do fármaco escolhido, o tratamento é sempre prolongado e o animal deve ser seguido por um período de doze meses. O objetivo deste trabalho é abordar, detalhadamente, a demodicose canina prestando particular atenção às opções terapêuticas existentes e ao desenvolvimento de novas formas de tratamento.
Canine demodicosis is an inflammatory skin disease caused by the excessive proliferation of Demodex mites, a commensal of the skin of domestic canines. Demodex canis is the main etiologic agent, however there were recently identified two other species, D. injai and D. cornei. This disease has a strong genetic and immunologic component and affects mostly young animals. There are different presentations of demodicosis, which influence the diagnostic and therapeutic approach. With the development of new antiparasitic drugs the cure rate is higher, however the risk of relapse remains. The treatment is based on weekly application of amitraz rinses, usually associated with the administration of a macrocyclic lactone. Regardless the chosen drug, it’s a long term treatment and the animal should be followed for a twelve month period. The goal of this presentation is to discuss, in detail, canine demodicosis with paying particular attention to existing therapeutic options and the development of new forms of treatment.
