CHEMICAL COMPOSITION VARIABILITY IN THE Uncaria tomentosa (cat’s claw) WILD POPULATION

Uncaria tomentosa (cat's claw) is a vine widely distributed throughout the South-American rainforest. Many studies investigating the chemical composition of cat's claw have focused on the pentacyclic (POA) and tetracyclic oxindole alkaloids (TOA), quinovic acid glycosides (QAG), and polyphenols (PPH). Nevertheless, it is still uncertain how environmental factors affect chemical groups. The aim of this work was to better understand the influence of environmental factors (geographic origin, altitude, and season) on cat's claw chemical composition. Stem bark, branches and leaf samples were extracted and analyzed by HPLC-PDA. The data obtained were explored by multivariate analysis (HCA and PCA). Higher amounts of oxindole alkaloids and PPH were found in leaves, followed by stem bark and branches. No clear relationship was verified among geographic origin or altitude and chemical composition, which remained unchanged regardless of season (dry or rainy). However, three oxindole alkaloid chemotypes were clearly recognized: chemotype I (POA with cis D/E ring junction); chemotype II (POA with trans D/E ring junction); and chemotype III (TOA). Thus, environmental factors appear to have only a minor influence on the chemical heterogeneity of the cat's claw wild population. Nevertheless, the occurrence of different chemotypes based on alkaloid profiles seems to be clear.

La cuestión del poder neutral en Schmitt

El artículo busca mostrar la importancia que la teoría del pouvoir neutre de B. Constant/ tuvo en la interpretación que Carl Schmitt hace de las funciones del Reichspräsident, en los años veinte hasta el nazismo. Aun cuando Schmitt critica al romanticismo, del cual al autor de Adolphe es una figura clave, igualmente reconoce que Constant teorizó la institución constitucional más adecuada para enfrentar las situaciones críticas, cuando la constitución debe autodefenderse mediante poderes legales pero excepcionales.

Ectonucleotidase activities in Sertoli cells from immature rats

Sertoli cells have been shown to be targets for extracellular purines such as ATP and adenosine. These purines evoke responses in Sertoli cells through two subtypes of purinoreceptors, P2Y2 and P A1. The signals to purinoreceptors are usually terminated by the action of ectonucleotidases. To demonstrate these enzymatic activities, we cultured rat Sertoli cells for four days and then used them for different assays. ATP, ADP and AMP hydrolysis was estimated by measuring the Pi released using a colorimetric method. Adenosine deaminase activity (EC 3.5.4.4) was determined by HPLC. The cells were not disrupted after 40 min of incubation and the enzymatic activities were considered to be ectocellularly localized. ATP and ADP hydrolysis was markedly increased by the addition of divalent cations to the reaction medium. A competition plot demonstrated that only one enzymatic site is responsible for the hydrolysis of ATP and ADP. This result indicates that the enzyme that acts on the degradation of tri- and diphosphate nucleosides on the surface of Sertoli cells is a true ATP diphosphohydrolase (EC 3.6.1.5) (specific activities of 113 ± 6 and 21 ± 2 nmol Pi mg-1 min-1 for ATP and ADP, respectively). The ecto-5'-nucleotidase (EC 3.1.3.5) and ectoadenosine deaminase activities (specific activities of 32 ± 2 nmol Pi mg-1 min-1 for AMP and 1.52 ± 0.13 nmol adenosine mg-1 min-1, respectively) were shown to be able to terminate the effects of purines and may be relevant for the physiological control of extracellular levels of nucleotides and nucleosides inside the seminiferous tubules.

Uma interpretação do Primeiro Milagre Econômico Alemão (1933-1944)

The German Third Reich was successful in reaching its economical objectives. It is intended to explain the causes of the First German Economic Miracle, fitting its economic system into the category of command economy, which does not confuse itself with the centrally planned economy. Thus, in the first section, we describe the so adopted politics in this period and explain how they had led to the recovery of the German economy. The second section evaluates global indicators of economic performance and population welfare. We are looking for to demonstrate the hypothesis that the Nazi economy was efficient. Such efficiency is explained by the characteristics of the German model.

Do individual e do coletivo: sobre aproximações entre o pensamento de Freud e Marx

O objetivo deste artigo é discutir a aproximação teórica entre duas vertentes distintas de pensamento que, inicialmente, pode parecer improvável: a psicanálise e o marxismo. O texto discorre sobre a reflexão da gênesis do problema político, interpretando sociedade e indivíduo como inter-relação da natureza humana, conectando, a partir desse princípio, o problema político e o problema psicológico, este se situando como base original daquele. Portanto, no entrecruzamento de sociedade, poder político e natureza humana, expande-se um campo de investigação que se abre a diversas possibilidades, inclusive à aproximação teórica entre as ideias de Marx e Freud. Dentre diversos autores que discutem o freudomarxismo e o posicionamento de Sigmund Freud, diante das ideias de Karl Marx, será dada exclusividade a Wilhelm Reich, Herbert Marcuse e a Ludwig Marcuse. Para uma crítica às ideias de Herbert Marcuse e análise da inter-relação entre marxismo e psicanálise, por sua vez, recorre-se ao filósofo marxista Louis Althusser e a outros analistas e críticos dessas mesmas ideias.

Inniskillin fonds, 1970-2014, n.d.

Inniskillin Wines was founded by Karl Kaiser and Donald Ziraldo in 1975 in Niagara-on-the-Lake, Ontario. They had met the previous year, when Karl Kaiser, a winemaker and chemist, purchased some grapes from Donald Ziraldo, who owned and operated Ziraldo Nurseries. The two shared a vision of producing better quality Canadian wines and formed a partnership, with Kaiser making the wine and Ziraldo serving as company President. In 1975, they were granted a winery license by the LCBO, the first one granted since 1929. The company name Inniskillin was derived from the Inniskilling Fusilliers, an Irish regiment whose Colonel once owned the land that Ziraldo Nurseries occupied. This was the original site of the winery, although in 1978 the winery moved to the Brae Burn Estate, their current location. In 1982 the winery expanded by 50 acres with the addition of the Montague Vineyard, and another 50 acres was acquired in 1991. The Niagara-on-the-Lake vineyard produces single vineyards bottlings of Chardonnay, Pinot Noir, Merlot and Pinot Grigio/Pinot Gris. In 1984, Karl Kaiser began producing icewine from Vidal grapes frozen naturally on the vine. Inniskillin garnered international acclaim for the quality of their icewines, receiving the prestigious Grand Prix d’Honneur at VinExpo in 1991, for their 1989 Vidal icewine. This established Inniskillin as a producer of world class wines, while also raising the profile of Canadian wines in general. The company branched out their operations, first acquiring vineyards in the Napa Valley in 1989 to form Inniskillin Napa (producing wines under the Terra label), and in 1994 establishing Inniskillin Okanagan in the Okanagan Valley in British Columbia. The Napa valley venture ceased in the mid 90’s, while Inniskillin Okanagan continues to operate. In 2006, Karl Kaiser and Donald Ziraldo left Inniskillin. Kaiser retired, while Ziraldo became chair of the Vineland Research and Innovation Center (2006-2011), and remains involved in the wine industry. In 2007, Bruce Nicholson joined Inniskillin as winemaker. Nicholson continues to produce award-winning wines under the Inniskillin label, receiving the top award, the Premio Speciale Gran Award, at Vinitaly 2009 for his 2006 Gold Vidal and his 2006 Sparkling Vidal Icewine. In 2012, he received several awards for the 2008 Riesling Icewine, including gold at the International Wine and Spirits Competition in London, UK, the San Francisco International Wine Championships, and Selections Mondials des Vins Canada.

Donald Ziraldo Fonds, 1968-2012, n.d.

Donald J. P. Ziraldo, C.M., BSc., LLD was born in St. Catharines, Ontario on October 13, 1948 to Fredrick and Irma (Schiratti) Ziraldo. He graduated Denis Morris High School in St. Catharines in 1967, and received his B.Sc. in Agriculture at the University of Guelph in 1971. In 1974, Ziraldo was running Ziraldo Nurseries when he met Austrian born schoolteacher, chemist and winemaker Karl J. Kaiser. They realized that there was a gap in the premium varietal wine market and decided to plant a premium traditional European variety of grape vine species, the Vitis vinifera. This was an innovation in the Niagara region because the current wine producers were not using premium European grapes at the time. Ziraldo and Kaiser founded and then formally incorporated Inniskillin Wines Inc. in Niagara-on-the-Lake, Ontario on July 31, 1975. Ziraldo successfully lobbied General George Kitching, CEO of the LCBO, for a winery license. In 1975, Kitching granted him a winery license, the first in Ontario since Prohibition ended. From the beginning, there was a division of labour where Kaiser focused on the winemaking and Ziraldo focused on the marketing and promotion of the wines. Ziraldo also became president of the company. Ziraldo and Kaiser worked on improving their winemaking techniques and promoting their products and company. Ziraldo has been called ‘one of the founding fathers of the Canadian wine industry’, and it is widely acknowledged that both men played a large role in the success and growth of the Canadian wine industry. Together they pioneered the estate winery movement in Canada. A major turning point Inniskillin came in 1984 when Karl Kaiser successfully harvested the first Icewine crop from frozen grapes on the vine and bottled Eiswein Vidal (Icewine). In 1990, Inniskillin received worldwide recognition for this Icewine when their 1989 Vidal Icewine won the most prestigious award in the wine world, the Grand Prix d’Honneur, given at Vinexpo in France. This victory has been called ‘the award heard round the world’ and it launched Inniskillin into the international wine arena. At the same time, this helped lift the profile of Canadian wines in general. Inniskillin not only became Canada’s leading producer of Icewine, but it also became known for producing ‘one of the world’s great wines’. After the 1990 award, Ziraldo began a major public relations campaign to promote Inniskillin and build Icewine into a worldwide brand. He travelled broadly every year to promote the brand and products and networked extensively with politicians, celebrities, chefs, sommeliers, etc. To ensure worldwide and long-term success, Ziraldo introduced Icewine to Asia and the United States which were new markets. He developed a new Icewine glass with George Riedel. Tony Aspler has called Ziraldo ‘Canada’s Wine Ambassador’. Ziraldo was President of Inniskillin Wines Inc. (Niagara) from 1975 to 2006. In 1992, Inniskillin merged with Cartier Wines, and in 1993 Cartier Inniskillin Vintners Inc. merged with T.G. Bright & Co. Limited, forming the new company Vincor International Inc. Inniskillin wines was now a subsidiary of Vincor. Ziraldo became a Director at Vincor International Inc. from 1993 to 2004. From 1989 to the mid 1990s, Ziraldo also became President of Inniskillin Napa, in Napa Valley, California. Inniskillin purchased Napa Valley vineyards and produced wines under the Terra label. In 1994, Ziraldo set up a subsidiary estate winery of Inniskillin in Oliver, British Columbia which was called Inniskillin Okanagan Vineyards Inc. He became President of the winery. This started as a partnership between Inniskillin and the local Inkameep Indian Band in the Okanagan. In 2006, Ziraldo left Inniskillin and since that time he has been involved in other Icewine related ventures such as running Ziraldo Estate Winery and producing Ziraldo Riesling Icewine 2007. He also is in partnership with the Niagara based Equifera Estate Winery to produce Equifera Icewine. His most recent projects include planting Picolit grapes in his parent’s hometown, in a project called Picolit Di Fagagna and becoming Managing Director of the Senhora Do Convento Port Winery in Portugal. Donald Ziraldo was instrumental in the creation of the Vintners Quality Alliance (VQA) in Ontario and was its founding Chair from 1988-1995. The VQA was established as a regulatory and appellation system which secured the quality and origin of Canadian wines made under this system. The VQA designation and bottle label gave the consumer confidence that the wines they were purchasing were 100% local products. The VQA system was set up first in Ontario and then in British Columbia.
