Abstract:

Borage (Borago officinalis L.) is a wild vegetable appreciated as a folk medicine and for culinary preparations. The introduction of borage as a specialized cultivation would allow for the diversification of vegetable crops and would widen the offerings of raw and minimally processed leafy vegetables. Thus, the aim of the research was to evaluate the quality and shelf-life of fresh-cut borage stored at different temperatures. Borage plants were grown during the autumn–winter season and immediately minimally processed after harvest. Fresh-cut borage leaves packed in sealed bags were stored at 2 or 6 °C for 21 d. Weight loss, total soluble solids (TSS), titratable acidity (TA), ascorbic acid, nitrates, leaf color characteristics and overall quality were determined through the storage period. Borage plants were deemed suitable for minimal processing. Storage temperature significantly influenced the rate of quality loss. Borage leaves had an initial nitrate content of 329.3 mg kg−1 FW that was not affected by temperature or storage. TSS and TA were higher in leaves stored at 6 °C. TSS, TA and ascorbic acid content increased during storage. Minimally processed borage leaves stored at 2 °C had lower weight loss and leaf color modifications during storage and a longer shelf life than those stored at 6 °C, so were still marketable after 21 d of storage.

Abstract:

Borage (Borago officinalis L.) is a hairy pubescent herb known throughout the world for its folk medicinal uses, as well as for many culinary uses. There is still little information on the cultivation needs of this species, especially for its use as vegetable crop and as fresh-cut produce. Hence, the aim of the research was to study the effects of agronomic practices on yield and quality of borage and on the storability as minimally-processed product. Two experiments were carried out in two consecutive years in order to evaluate the effect of plant density and plastic mulching on yield and quality of two borage accessions at harvest and during storage as minimally-processed produce for 14 days at 4 °C. The highest plant density (8 plants m2) determined the highest yield of plants and minimally-processed leaves with good quality retention during storage. Mulching had a positive effect on earliness, yield, and shelf life of minimally-processed leaves but also increased nitrate accumulation and reduced ascorbic acid content. Borage plants with lower spacing grown on mulched soil showed the best yield of plants and minimally-processed leaves irrespective of the borage accession tested. Borage plants can be used to produce minimally-processed entire leaves with good quality characteristics.

Abstract:

Alfalfa mosaic virus (AMV) has a wide host range and is distributed throughout the world. It causes disease in several vegetable crops, including bean, celery, lettuce, pea, pepper, and tomato (1). In Spain, it has been found naturally infecting alfalfa, pepper, and tomato. During the autumn of 1999, in the area of Zaragoza (northeastern Spain), several plants expressing foliar yellow mosaic symptoms were observed in borage grown for human consumption in open field plots. The commercial value of the symptomatic plants was greatly reduced. The symptoms were similar to those previously obtained in greenhouse-grown borage plants mechanically inoculated with three tomato isolates of AMV (2). The following indicator species, including virus-free borage plants, were mechanically inoculated with sap from leaves of symptomatic borage plants, and reactions were recorded: chlorotic and necrotic local lesions on Tetragonia expansa and Vigna unguiculata; chlorotic local lesions and systemic mosaic on Chenopodium quinoa, C. amaranticolor, Cucumis sativus ‘Marketmore’, Gomphrena globosa, and Nicotiana glutinosa; systemic mosaic, sometimes associated with localized reactions, on Ocimum basilicum, Capsicum annuum ‘Doux des Landes’ and ‘Yolo Wonder’, N. benthamiana, N. clevelandii, N. rustica, N. sylvestris, N. tabacum ‘Paraguay’ and ‘Xanthi nc’, Petunia hybrida, Physalis floridana, and Solanum melongena ‘Cerna krazavitska’. The reactions are in agreement with the indicator host reactions described for AMV (1). Symptoms on virus-free borage plants mechanically inoculated with sap from symptomatic borage and from inoculated C. amaranticolor and O. basilicum experimental hosts were similar to those observed in naturally infected borage. Positive serological reactions (A405 values more than three times greater than those of the negative controls) in double-antibody sandwich enzyme-linked immunosorbent assay using commercially prepared antiserum against AMV (Agdia, Inc., Elkhart, IN) were obtained with extracts of naturally infected borage leaves and with systemically infected indicator species. Alfalfa plots located in the vicinity of the symptomatic borage plants could be the source of virus for borage infections. To our knowledge, this is the first report of natural AMV infection in Borago spp. References: (1) E. M. J. Jaspars and L. Bos. CMI/AAB. No. 229, 1980. (2) M. Luis-Arteaga and J. M. Alvarez. Inf.

Abstract:

Borage (Borago officinalis L.) is a traditional vegetable grown and consumed in some Spanish regions. The objective of this study was to determine the variability and evolution of fatty acid composition in a borage germplasm collection formed by wild types, breeding lines, commercial varieties, and landraces. Fatty acids were analysed in petioles, the commonly edible part of the leaves, and the leaf blades, the by-product of the borage industry, in two growth stages: at the optimal harvest period (120 days after sowing) and at the end of the harvest period (150 days after sowing). The results showed that for each of the eight fatty acids identified, there were significant differences among the twelve borage genotypes depending on the developmental plant stage at sampling date and the part of the leaf analysed, the interaction effect also being statistically significant. The main polyunsaturated fatty acids identified were: linoleic acid (18:2 n6, LA), α-linolenic acid (18:3 n3, ALA), γ-linolenic acid (18:3 n6, GLA), and stearidonic acid (SDA, 18:4, n-3), account for approximately 70% of polyunsaturated fatty acids. Blue-flowered genotypes differ from white-flowered genotypes by their high content of ALA and SDA, which can be exploited in borage breeding programs. Petioles from young plants present higher n6 fatty acids, while older plants produce a great amount of n3 fatty acids. Besides, the higher content of ALA in the leaf blades gives them a good dietary potential. All these fatty acids, with multiple health benefits, support the nutraceutical interest of borage leaves (both petioles and leaf blades) for human consumption, animal feeding, medicine, and pharmacy.

Abstract:

Borage (Borago officinalis) is an oilseed crop that is being evaluated as an alternative crop in North Dakota. During September 2004, borage plants in a field in Cass County, North Dakota were dying from a watery soft rot. The main stems and lateral branches were affected, and affected plants were usually completely lodged and prostrate. Dead plants had bleached and shredded stems with black sclerotia (9.1 ± 3.0 × 2.6 ± 0.5 mm) inside the pith and on the epidermis. At the time of observation, borage plants were flowering and forming pods and seed. Approximately 60% of the plants were visually affected by the watery soft rot. Sclerotia were collected from diseased plants, soaked in a 0.5% NaOCL solution for 30 s, air dried, and placed in petri dishes containing potato dextrose agar (PDA). A fungus grew from the plated sclerotia that subsequently produced white mycelium and black sclerotia (4.8 ± 1.2 × 2.5 ± 1.0 mm), which is characteristic of Sclerotinia sclerotiorum (Lib.) de Bary (3). To confirm pathogenicity, borage plants were inoculated in the greenhouse with a S. sclerotiorum isolate from field-infected borage. Thirteen borage plants were grown from seed in the greenhouse under natural sunlight at a temperature range of 24 ± 3°C. When plants were at the four-leaf stage (approximately 16 cm high), the second leaf was excised from each plant with the petiole remaining on the plant. The leafless petioles were inoculated using a method previously described (2). Petioles of 10 plants were inoculated with PDA containing mycelium of the S. sclerotiorum borage isolate, while petioles of five plants were inoculated with PDA to serve as a control. Three days after inoculation, plants inoculated with the S. sclerotiorum borage isolate were beginning to wilt and 5 days after inoculation, these plants were completely wilted and prostrate, similar to observations made on field-infected plants. Sclerotia collected from the diseased, inoculated plants were placed on PDA, and S. sclerotiorum was successfully recovered. Control plants inoculated with PDA did not show any disease symptoms. Other plant genera in the Boraginaceae are known hosts of S. sclerotiorum (1); however, to our knowledge, this is the first report of borage as a host. References: (1) G. J. Boland and R. Hall, Can.

Abstract:

The common borage, Borago officinalis L., is of Euro-Mediterranean origin, but is found extensively in the wild. It is also cultivated as a garden plant, crop vegetable, or pharmaceutical herb. Analysis of random amplified polymorphic DNAs (RAPDs) revealed high levels of genetic diversity among 10 borage wild accessions and seven cultivars, which included five white-flowered selections grown in northern Spain for petiole production, and two blue-flowered lines used medicinally. These latter two cultivars and populations, sampled far from the original habitat of the species, were closely related to wild borage populations from northern Europe. The two medicinal cultivars did not differ from each other, while those used for petiole production differed significantly from their Spanish wild relatives. Differences among the 17 populations accounted for 41.4% of the total genetic variability; this value increased to 50.8% when only the 10 wild populations were considered. Population differentiation and within-population variability are discussed in relation to mating system, selection, and conservation practices.

Abstract:

There is currently a growing interest in oils characterised by specific medicinal, cosmetic, or dietary properties. For this reason, the seeds of two plants, milk thistle (Silybum marianum Gaertn) and borage (Borago officinalis L.), were studied by subjecting them to the process of cold pressing. The extracted oils were then examined in terms of their chemical composition and biological activity, and qualitatively analysed with the use of FTIR spectroscopy. The oils contained linoleic and octadecenoic acids in amounts of 47.84%, 35.31% (milk thistle oil) and 35.43%, 25.18% (borage oil). They were characterised by low water content, roughly 0.088% for thistle and 0.075% for borage, and simultaneously relatively high phosphorus content, reaching, respectively, 47.7 and 33.1 mg·kg−1. The mean peroxide value was 4.22 for milk thistle and 2.83 mmolO2·kg−1 for borage, and the acid number was 5.17 and 3.9 mgKOH·g−1, respectively. FTIR spectroscopy was used to conduct a qualitative analysis, which revealed slight discrepancies in intensity at 3005 cm−1, which confirmed differences in the content of fatty acids and oil pigments between the oils. The obtained results provided information on the applicability of the studied seeds and oils obtained therefrom as basic components of pharmaceutical and cosmetic products with potential health benefits.

Abstract:

European borage (Borago officinalis L.) is a cultivated medicinal plant in Iran, but common agronomic practices about profitable cultivation are mostly unknown. A 2-yr field experiment (2013 and 2014) was conducted in Guilan Province of northern Iran to evaluate European borage yield and profitability under irrigation with surface and drip irrigation systems. Treatments included (i) rainfed production (I0, control), (ii) single irrigation (I1) applied with surface irrigation alone and drip irrigation alone, and (iii) two irrigations (I2) applied with surface irrigation alone and drip irrigation alone. In 2013, I1 increased flower dry weight by 41.0% and seed weight by 7.1% compared with rainfed European borage, while with I2, the increases in those traits were 23.4% and 0.6%, respectively. In 2014, I1 increased flower dry weight by 78.0% and seed weight by 21.3% compared with rainfed European borage, while the respective increases were 51.8% and 17.3% with I2. On average, drip irrigation provided higher flower dry weight and seed weight by 39.3% and 12.6%, respectively, compared with surface irrigation. Drip irrigation increased variable costs by 165.2% compared with surface irrigation but resulted in increased gross income by 23.2%. Partial budgeting showed that I1 with drip irrigation provided the maximum net profit in both years. Based on the final rate of return, investing in the treatment I1 with drip irrigation was better than investing in the other treatments. Moreover, I1 with drip irrigation showed the highest value of economic water productivity and could be considered for improving the net income of European borage farmers.

Abstract:

Acute respiratory distress syndrome (ARDS) is a life-threatening condition in which the lungs become severely inflamed, causing the alveoli to constrict or fill with fluid, which prevents the lungs from functioning properly. This disease becomes more dangerous when it occurs in patients with diabetes. Because of the clinical condition of these patients, it is not possible to treat them with usual medicines. One of the best options for treating these people is to use herbs. Borage (Borago officinalis) is a medicinal herb that, in addition to its anti-inflammatory properties, is also able to control blood sugar. Therefore, in the current study, the effect of borage oil was considered on the signaling pathway of the NLRP3 inflammasome complex, TLR4, and serum levels of inflammatory cytokines (IL-1? and IL-18) in type II diabetic patients with ARDS. For this purpose, 25 diabetic type II patients with ARDS were divided into three groups by ARDS Berlin Definition. Then, after providing the demographic and clinical characteristics of the patients, they were treated with 30 mg/day borage oil for seven days. The expression of NLRP3 and TLR4 genes (by Real-time PCR technique) and serum levels of IL-1? and IL-18 (by ELISA test) were evaluated before and after treatment with borage oil through blood samples taken from patients. The results showed that serum levels of inflammatory cytokines (IL-1? and IL-18), NLRP3 gene, and TLR4 gene were significantly decreased in diabetic type II patients with mild ARDS by treating with borage oil. IL-1? serum level and TLR4 were significantly decreased in diabetic type II patients with moderate ARDS. But there was not any significant decrease or increase in IL-1?, IL-18, NLRP3 gene, and TLR4 gene in diabetic type II patients with severe ARDS after 7 days of treatment with borage oil. According to the obtained results, borage oil can act as a double-edged blade. Thus, in the early and middle stages of ARDS, borage oil can be effective in reducing the inflammasome pathway of inflammation and also reduce blood sugar levels in these diabetic patients. But in the severe stage of ARDS, it not only does not help to treat the ARDS; it also increases systolic and diastolic blood pressure in diabetic patients.

A impregnação de polímeros com princípios ativos de fármacos usando o dióxido de carbono a alta pressão constitui-se em uma das formas de processamento de polímeros para obtenção de sistemas de liberação controlada. A modelagem e a simulação do processo de impregnação são especialmente importantes para a previsão da viabilidade técnica do processo e a escolha das melhores condições operacionais com redução dos esforços experimentais. Nesse sentido, a presente dissertação tem como objetivo modelar e simular a impregnação de membranas de poliuretano com óleo de borage usando CO2 denso para aplicação no tratamento de feridas dérmicas. Para tanto, é crucial a descrição adequada do comportamento termodinâmico do sistema ternário CO2-óleo de borage-poliuretano a alta pressão, que não é uma tarefa trivial, pois necessita de dados de equilíbrio de fases dos sistemas binários correspondentes ainda pouco estudados na literatura. A modelagem e a simulação do processo de dessorção de CO2 em poliuretano foram realizadas utilizando-se as soluções analítica e numérica da 2ª. lei de Fick para descrição do fenômeno de transferência de massa. A determinação da quantidade máxima de CO2 sorvida no poliuretano foi obtida pela extrapolação da curva de dessorção até o tempo zero para diferentes condições de temperatura, pressão e tempo de sorção. O emprego das soluções analítica e numérica da 2ª. lei de Fick geraram resultados semelhantes tanto para o coeficiente de difusão quanto para a quantidade de CO2 sorvida pelo poliuretano. A predição do comportamento termodinâmico do óleo de borage em CO2 denso foi feita a partir da correlação de dados de solubilidade usando a equação de estado de Peng-Robinson com dois tipos de regra de mistura: a clássica e a LCVM. Devido à complexidade do sistema e a ausência de dados experimentais, as propriedades físico-químicas do óleo de borage foram estimadas por métodos de contribuição de grupos. Os resultados da correlação da solubilidade do óleo de borage em CO2 indicaram que o tipo de regra de mistura não é o fator determinante vi para o bom ajuste do modelo aos pontos experimentais, mas sim a quantidade de parâmetros ajustáveis utilizados. Observou-se que apenas a regra de mistura clássica com dois parâmetros ajustáveis dependentes da temperatura é capaz de descrever satisfatoriamente o comportamento termodinâmico desse sistema. A modelagem do equilíbrio de fases do sistema ternário foi feita através da predição do coeficiente de partição do óleo de borage entre as fases polimérica e fluida, a partir dos dados experimentais dos sistemas binários, usando-se a teoria do equilíbrio de fases e modelos específicos. Observou-se que, apesar da escassez de dados de equilíbrio de fases para os sistemas binários, é possível fazer uma avaliação qualitativa satisfatória a partir do cálculo preditivo do coeficiente de partição do óleo de borage. Os resultados mostraram que a ordem de grandeza do coeficiente de partição calculado é a mesma dos valores obtidos a partir dos dados experimentais de impregnação.

This study aimed to obtain semisolids formulations and lipid core nanocapsules containing borage oil associated or not with betamethasone dipropionate, for their application in the treatment of atopic dermatitis. A gel-cream containing borage oil was prepared and presented satisfactory results for performed tests (pH, spreadability and viscosity suitable for topical application). The in vivo assay showed topical anti-inflammatory action of the oil in rats. Additionally, nanocapsule suspensions containing borage oil and betamethasone dipropionate were prepared by interfacial deposition of preformed polymer method and were characterized. The colloidal suspensions, showed a slightly acid pH (6.0-6.2), nanosized particles (180-210 nm), with a low polydispersity index (<0.1), negative zeta potential (-9 to -16 mV), betamethasone content was close to theoretical and encapsulation efficiency of approximately 100%. After 15 days of storage at room temperature, only zeta potential. Photodegradation study of of betamethasone dipropionate using UVC light was performed. It was observed a protection against photodegradation conferred by the nanostructured drug delivery systems. The in vitro release study of betamethasone dipropionate from nanocapsule suspensions demonstrated the ability of nanostructures to decrease the drug release. These nanostructures were incorporated into hydrogels (Carbopol® Ultrez and Cellosize®). The hydrogels were evaluated and showed acidic pH, nanosized particle, betamethasone content near to theoretical (0.5 mg / g) and pseudoplastic behavior (Herschel-Bulkley model). In vitro release study of betamethasone dipropionate from the hydrogels demonstrated a reduced release of the drug in the different analysis times, as compared with hydrogels containing the non-associated drug. The in vivo anti-inflammatory assay showed the anti-inflammatory activity of the hydrogels containing the nanostructures, which can demonstrate the drug and the oil activity when combined with polymeric nanocapsules.
Esse trabalho buscou obter formulações semissólidas e nanocápsulas de núcleo lipídico contendo o óleo de borragem associado ou não ao dipropionato de betametasona, visando sua aplicação no tratamento da dermatite atópica. Uma formulação semissólida do tipo creme-gel contendo o óleo de borragem foi preparada e apresentou resultados satisfatórios para os testes empregados (pH, espalhabilidade e viscosidade adequadas para aplicação tópica). O ensaio in vivo realizado em ratos Wistar evidenciou a ação anti-inflamatória tópica do óleo. Adicionalmente, suspensões de nanocápsulas foram preparadas pelo método de deposição interfacial de polímero pré-formado, contendo o óleo de borragem e dipropionato de betametasona, as quais foram caracterizadas em relação ao tamanho médio de partículas, índice de polidispersão (PdI), potencial zeta, microscopia de transmissão eletrônica, pH, teor de fármaco e eficiência de encapsulamento. As formulações apresentaram pH levemente ácido (6,0-6,2), partículas de tamanho nanométrico (180-210 nm), baixo índice de polidispersão (< 0,1), potencial zeta negativo (-9 a -16 mV), teor de betametasona próximo ao teórico e eficiência de encapsulamento de, aproximadamente, 100%. No período de 15 dias de armazenamento, a temperatura ambiente, apenas o potencial zeta. O estudo de fotodegradação do dipropionato de betametasona frente à luz UVC foi realizado e evidenciou a relevância dos sistemas nanoestruturados na proteção do fármaco. O estudo de liberação in vitro a partir das suspensões demonstrou a capacidade das nanocápsulas em reduzir a liberação do fármaco. As nanoestruturas foram incorporadas em hidrogéis (Carbopol® Ultrez e Cellosize®), os quais foram avaliados quanto ao pH, tamanho de partículas, espalhabilidade, propriedades reológicas e teor de fármaco. Os hidrogéis apresentaram pH ácido, tamanho de partícula nanométrico, teor de betametasona próximo ao teórico (0,5 mg/g) e comportamento pseudoplástico (modelo Herschel-Bulkley). No estudo de liberação in vitro do dipropionato de betametasona a partir dos hidrogéis verificou-se uma liberação menor do fármaco nos diferentes tempos de análise em comparação com os hidrogéis contendo o fármaco não associado. O ensaio in vivo para avaliar a atividade anti-inflamatória dos hidrogéis contendo as nanoestruturas foi também realizado, sendo possível comprovar a atividade do fármaco e do óleo quando associados à nanocápsulas poliméricas.

Die eingereichte Dissertation mit dem Thema „Heterogen katalysierte Hydrodehalogenierung von Borhalogeniden im Rahmen eines in sich geschlossenen BNHx-Recyclingkonzepts“ beinhaltet drei für das BNHx-Recycling zentrale Reaktionsschritte: Supersäureaufschluss, Hydrodehalogenierung und den Basenaustausch. Mit Hilfe dieser drei Schritte ist es möglich, die Zersetzungsrückstände von BH3NH3(Polyaminoboran, Borazin und Polyborazylen) wieder in BH3NH3 zu überführen, ohne teure Reduktionsmittel wie LiAlH4 oder Hydrazin verwenden zu müssen. Das Verfahren ermöglichte in einem Durchlauf die Gewinnung von 60 % der eingesetzten Menge an BH3NH3 ohne eine Erzeugung von Abfallprodukten. Mit Hilfe der Chloralkalielelektrolyse kann das Verfahren an Wind- bzw. Solarkraftwerke gekoppelt und über diese alle benötigten Ausgangsstoffe hergestellt werden. Die katalytische Erzeugung von B-H-Spezies auf der Grundlage der Aktivierung von molekularem Wasserstoff ist als Schwerpunkt dieser Arbeit zu sehen. Die mechanistischen Studien lieferten ein genaueres Verständnis über fundamentale Zusammenhänge zwischen dem Lösungsmittel Et3N und der Wasserstoffbereitstellung über die N-CH2-Gruppierung sowie der Wirkungsweise des Katalysators.

Abstract:

Trichogramma carverae Oatman and Pinto is mass-released for biological control of the leafroller pest, light brown apple moth, Epiphyas postvittana (Walker) in Australian vineyards. Parasitoid performance can, however, be constrained by a lack of suitable adult food and no information is available on the effect of nectar on the parasitism and longevity of T. carverae. To address this, the effect of alyssum, Lobularia maritima (L.) flowers on E. postvittana parasitism was studied in a vineyard experiment with and without releases of T. carverae. Egg parasitoid activity was assessed with E. postvittana egg 'sentinel cards' and no parasitism was recorded in plots without T. carverae releases. Where T. carverae were released, there was no significant enhancement of parasitism by the presence of L. maritima flowers. Three hypotheses were subsequently tested to account for the lack of an effect: (i) T. carverae does not benefit from L. maritima nectar, (ii) T. carverae was feeding on nectar from other flowering plants (weeds) present in the vineyard, (iii) T. carverae was feeding on sugars from ripe grapes. A growth-cabinet experiment using potted L. maritima plants with and without flowers did not support hypothesis one. No parasitism was recorded after day two for T. carverae caged without flowers whilst parasitism occured until day eight in the presence of flowers. A laboratory experiment with common vineyard weeds (Trifolium repens, Hypochoeris radicata, Echium plantagineum) as well as L. maritima did not support hypothesis one but gave partial support to hypothesis two. Survival of T. carverae was enhanced to a small but statistically significant extent in vials with intact flowers of L. maritima, white clover (T. repens) and catsear (H. radicata) but not in vials with flowering shoots of these species from which flowers and flowering buds had been removed. Paterson's curse (E. plantagineum) flowers had no effect on T. carverae survival. In a laboratory study, punctured grapes significantly enhanced T. carverae survival compared with a treatment without grapes, supporting hypothesis three. Trichogramma carverae performance in the field experiment was probably also constrained by relatively cool and wet weather. Further work on the enhancement of T. carverae efficacy by L. maritima and other carbohydrate sources is warranted. Greenhouse and field experiments were conducted to investigate whether T. carverae benefit from different groundcover plant species. Ten T. carverae adults (<24h after eclosion) were caged with different groundcover species and a control with no plant materials. Epiphyas postvittana egg sentinel cards were used to measure parasitism and longevity was recorded visually. Survival and realised parasitism of T. carverae was significantly higher in L. maritima than in Brassica juncea, Coriandrum sativum, shoots of these species from which flowers had been removed and nil control treatments. A similar experiment with Fagopyrum esculentum (with- and without-flowers) and a control treatment showed that survival was significantly higher in intact F. esculentum than in without-flower and control treatments. There was no significant treatment effect on parasitism in the early stages of that experiment, though parasitism was recorded in the presence of F. esculentum flowers for 12 days, compared with 6 days in other treatments. Higher parasitism was observed in intact Borago officinalis than in the flowerless shoot, water only and no plant material control treatments in a third experiment. There was no significant treatment effect on parasitism. Fitted exponential curves for survival data differed significantly in curvature in the first, second and third experiments but the slope was a non-significant parameter in the second and third experiments. In a second series of laboratory experiments, one male and one female T. carverae were caged with groundcover species to investigate male and female longevity and daily fecundity. Both male and female longevity in F. esculentum and L. maritima treatments were significantly higher than on shoots of these species from which flowers had been removed, and than in the control treatments. Daily fecundity was significantly greater in the intact L. maritima treatment than in all other treatments. Fitted exponential curves for daily fecundity differed significantly in position and slope but not in curvature. There was no significant treatment effect on longevity or parasitism when a male and female were caged with intact B. juncea, B. officinalis or without-flower of these species, nor in the treatment with no plant materials. No parasitism was observed in a survey of naturally occurring egg parasitoids on two sites close to Orange and Canowindra in New South Wales, illustrating the importance of mass releases of T. carverae in biological control of E. postvittana. In an experiment on the Canowindra site, parasitism was significantly higher on day one and day two after T. carverae release when with-flower treatments were compared with without-flower treatments. Parasitism was significantly higher in the F. esculentum treatment than in C. sativum, L. maritima, vegetation without-flowers and control treatments on these dates. On day five, parasitism was higher in C. sativum than in all other treatments. There was no significant increase in parasitism in a second experiment conducted on the Orange site. Coriandrum sativum, F. esculentum and L. maritima appear to be suitable adult food sources for T. carverae and offer some scope for habitat manipulation in vineyards The adults of many parasitoid species require nectar for optimal fitness but very little is known about flower recognition. Flight cage experiments showed that the adults of T. carverae benefited from L. maritima bearing white flowers to a greater extent than was the case for light pink, dark pink or purple flowered cultivars, despite all cultivars producing nectar. Survival and realised parasitism on non-white flowers were no greater than when the parasitoids were caged on L. maritima shoots from which flowers had been removed. The possibility that differences between L. maritima cultivars were due to factors other than flower colour, such as nectar quality, was excluded by dyeing white L. maritima flowers by placing the roots of the plants in 5% food dye (blue or pink) solution. Survival of T. carverae was lower on dyed L. maritima flowers than on undyed white flowers. Mixing the same dyes with honey in a third experiment conducted in the dark showed that the low level of feeding on dyed flowers was unlikely to be the result of olfactory or gustatory cues. Flower colour appears, therefore, to be a critical factor in the choice of plants used to enhance biological control, and is likely to also be a factor in the role parasitoids play in structuring invertebrate communities. Provision of nectar producing plants to increase the effectiveness of biological control is one aspect of habitat manipulation, but care needs to be taken to avoid the use of plant species that may benefit pest species. Greenhouse experiments were conducted to investigate whether the adult E. postvittana and larvae benefit from nectar producing groundcover species. Newly emerged E. postvittana adults were caged with different groundcover species and a honey-based artificial adult diet. The longevity of male and female E. postvittana when caged with shoots of borage (B. officinalis) and buckwheat (F. esculentum) bearing flowers was as long as when fed a honey-based artificial diet. This effect was not evident when caged with shoots of these plants from which flowers had been removed. Longevity was significantly lower than in the artificial diet treatment when caged with coriander (C. sativum) or alyssum (L. maritima) irrespective of whether flowers were present or not. There was no significant treatment effect on the lifetime fecundity of E. postvittana. A second experiment with mustard (B. juncea) (with- and without-flowers), water only and honey-based artificial adult diet showed no significant treatment effects on the longevity of male and female E. postvittana or on the lifetime fecundity of E. postvittana. The anomalous lack of a difference between the water and honey-based diet treatments precludes making conclusions on the value of B. juncea for E. postvittana. Two greenhouse experiments were conducted to evaluate the effects of groundcover species on the larval development of E. postvittana. In the first experiment, larval mortality was significantly higher in C. sativum, and L. maritima than in B. juncea, B. officinalis and white clover (T. repens) a known host of E. postvittana. Coriandrum sativum and L. maritima extended the larval period. In B. juncea and B. officinalis, mortality did not differ from that in T. repens. In F. esculentum, larval mortality was significantly higher than in T. repens. A short larval period was observed on B. juncea, B. officinalis and F. esculentum. Fitted exponential curves for larval mortality differed significantly in curvature between plant treatments. Similarly, successful pupation was significantly lower in C. sativum, F. esculentum and L. maritima than in T. repens. The percentage of successful pupation in B. juncea and B. officinalis did not differ from F. esculentum and T. repens. Fitted exponential curves for pupation differed significantly in curvature. A similar trend was observed in a second experiment with potted plants. The overall results suggest that C. sativum and L. maritima denied benefit to E. postvittana adults and larvae, so could be planted as vineyard groundcover with minimal risk of exacerbating this pest. Overall results suggest that T. carverae require nutrients to reach their full reproductive potential and flowers provide such nutrients. Lobularia maritima and C. sativum may be considered 'selective food plants' for T. carverae whereas F. esculentum appears to be a 'non-selective food plant'; both T. carverae and E. postvittana benefited from it. Fruits such as grapes can be used as food resources in habitat manipulation and this merits further research. This result also suggests that within species flower colour is an important factor for flower selection in habitat manipulation.

O presente trabalho visou estudar a viabilidade de incorporação de agentes bioativos em curativos poliméricos utilizando dióxido de carbono supercrítico (CO2). Foram utilizados dois curativos comerciais: Foam Dressing (poliuretano) e Promogran® (colágeno e celulose regenerada oxidada). Como bioativos, foram testados o óleo de borage e o extrato de jambu. Foram realizados ensaios de sorção de CO2 supercrítico nessas matrizes poliméricas sob diferentes condições, de modo a potencializar a incorporação de agentes bioativos. Isto pode ser útil para futuros trabalhos na área de impregnação/deposição de agentes bioativos em curativos de espuma, já que é o primeiro estudo com estes tipos de material (curativos e bioativos) nestas condições experimentais. Os resultados mostraram que a melhor condição de sorção para ambos os polímeros foi obtida na temperatura de 308,15 K e densidade do CO2 igual a 850 kg.m-3. O melhor rendimento de impregnação para o óleo de borage em poliuretano (11,8 % m/m) ocorreu nessa mesma densidade do CO2 e na temperatura de 328,15 K. Para o extrato de jambu, o maior rendimento de incorporação na matriz de colágeno e celulose ocorreu nas condições de melhor sorção e com adição de etanol como cossolvente (6,4% m/m). Os resultados obtidos mostraram que a etapa controladora do processo de impregnação/deposição (SSI/SSD) é o equilíbrio de fases e apontam para a possível viabilidade técnica da impregnação de bioativos de origem natural em curativos poliméricos.
ABSTRACT The present work aimed to study the feasibility of incorporation of bioactive agents into polymeric dressings using supercritical carbon dioxide (CO2). Two commercial dressings were investigated: Foam Dressing (polyurethane) and Promogran (collagen and oxidized regenerated cellulose). The bioactives investigated were borage oil and jambu extract. Assays of supercritical CO2 sorption into these polymeric dressings were carried out under different conditions in order to enhance the incorporation of these bioactive agents into the polymer matrices. This can be useful for future works on impregnation/deposition area of bioactive agents in foam dressings, since the study is the first one using these materials (dressings and bioactives) at these experimental conditions. The results showed that the best sorption condition for both polymers was obtained at 308 K and CO2 density equal to 850 kg.m-3. The best impregnation/deposition yield for borage oil and polyurethane (11.8 % w/w) occurred also at this same CO2 density and temperature at 328,15 K. In the case of jambu extract, the highest incorporation yield into the collagen and cellulose matrix occurred under the conditions of highest sorption with the addition of ethanol as a cosolvent (6,4 % w/w). The results showed that SSI/SSD is controlled by phase equilibrium phenomenon and point towards the technical feasibility of this process.

Abstract:

Lipozyme TL IM from Thermomyces lanuginosus is widely employed for various enzymatic reactions such as esterification, hydrolysis, and alcoholysis. However, none of the publications is using Lipozyme TL IM as a biocatalyst to synthesize triacylglycerol (TAG) with fatty acid and glycerol because the silica gel carrier in Lipozyme TL IM aggregates with glycerol. Thus, most studies regarding the synthesis of TAG via lipase-catalyzed esterification have employed Novozym 435, one of the most expensive enzymes. In present study, we attempted to synthesize TAG using Lipozyme TL IM with glyceride, instead of glycerol, and fatty acid as a novel strategy; as a result, γ-linolenic acid (GLA) rich TAG was synthesized successfully via esterification using Lipozyme TL IM. In the first step, GLA was enriched into glyceride fraction from borage oil by C. rugosa lipase-catalyzed hydrolysis and the GLA rich glyceride was separated from the reaction mixture using short-path distillation. GLA was enriched up to 45.9% in glyceride fraction from an initial value of 20.6% under the optimum conditions, which are the temperature of 40 °C and the enzyme loading of 0.05% (based on the oil weight of the total substrate). In the second step, GLA rich TAG was synthesized with the GLA rich glyceride, instead of glycerol, and the fatty acid obtained from part of the GLA rich glyceride by saponification using Lipozyme TL IM as a biocatalyst. The optimum conditions were the temperature of 50 °C, the enzyme loading of 10%, and the vacuum level of 5 torr, respectively. Consequently, the maximum TAG conversion of ca. 93% was achieved after 24 h under the optimum condition.

Abstract:

Dibutyl tin and stannous dialkyldithiocarbamates were synthesized. A four-ball tester was used to evaluate the tribological performances of these additives plus organic borate in a mineral oil. The results indicate that the combination of an oil-soluble tin compounds such as dibutyl tin and stannous dialkyldithiocarbamates with organic borates gave better antiwear protection to base oil than either component separately. The surface examination of the rubbing zone indicated that the atomic concentration of tin produced on the boundary layers by such combinations was greater than those without borates. On the basis of the results of tribological and chemical investigation, an antiwear synergistic mechanism can be postulated in which borates with electron-deficient p orbits in boron catalyse the triboreduction of tin compounds on rubbing surfaces.

Optical parametric oscillator (OPO) and amplifier (OPA) devices are recognised as versatile coherent tunable spectroscopic sources. This is borne out by our previous work on OPOs based on bulk (3-barium borate (BBO) [1] and lithium niobate (LNB) [2], in which tunability and optical bandwidth are achieved by injection seeding with single-mode tunable diode lasers (TDL).

Abstract:

Abstract This paper describes a novel application of OF-boride layers on steel surfaces. The plasma-sprayed boron carbide powder on steel was diffusion annealed to form a suitable iron-hemiboride intermediate layer with a coefficient of thermal expansion between the coefficients for the steels used and ceramic coatings to create. In the next step, this system was completed with a second plasma-sprayed layer on aluminum oxide o zirconium oxide. The adhesion of these samples was checked after dynamic loading as a result of alternating thermal loads at 600, 800, 1000 or 1200 deg C. The resulting values were compared both with the adhesion values of the same ceramic coatings on steel without a boride intermediate layer and with the adhesion values of these ceramic coatings on steel that were borated according to the classic method in a boron carbide pack with activators. Paper includes a German-language abstract.

Abstract:

The poisoning of exhaust catalysts by phosphorus has lead to research to provide new additives packages to reduce or displace the use of ZDDP. In this research a four-ball tester was used to evaluate the tribological performances of organic borate ester containing nitrogen (BNO) combined with zinc dialkyldithiophosphate (ZDDP) or tin dialkyldithiocarbamates (SnDDC) in base oil respectively. The results indicate that the combination of these additives with organic borates ester can exhibit better antiwear synergism than either component separately without impairing load carrying abilities. Especially, the antiwear properties of oils can be improved significantly under optimal concentration ranges. Accordingly considerable amount of or ZDDP can be partially replaced by BNO in synergetic mixtures, or replaced completely by the combination of BNO with SnDDC. This might provide opportunities for the use of lower concentrations of S, P additives.

Abstract:

To investigate the solidification efficiency of sulfoaluminate cement (SAC) and to provide more information for formula optimization, SAC blending zeolite, accelerator and Dura fiber was used as matrix materials for solidification of simulated radioactive borate liquid waste. The simulated radioactive borate liquid waste was prepared with boric acid and sodium hydroxide using drinking water. The performances of solidified waste forms were evaluated mainly basing on matrix compressive strength and leachability. The 28d compressive strength of the solidified waste forms were tested according to Chinese National Standard GB 14569.1-1993, and experiments on water/freezing/irradiation/impact resistance were also carried out. Nuclides Sr, Cs and Co were substituted by their non-radioactive isotopes respectively in leachability test, and the testing procedures were consistent with Chinese National Standard GB 7023-1986. Experimental results showed that it was feasible to solidify borated liquid wastes with SAC. The 28d compressive strength was 13.9MPa, nearly twice of the standard in GB 14569.1-1993. Strength losses in water/freezing/irradiation/impact resistance tests met the demands of GB 14569.1-1993 well. In the leaching test, the 42d leaching rates were 3.39×10−5 cm/d, 4.45×10−5 cm/d and 4.07×10−7 cm/d for Sr2+, Cs+ and Co2+ respectively, much lower than GB 14569.1-1993 limits. Results of leaching test also showed that the leaching mechanism of Co2+ was different from that of Sr2+ and Cs+.
