Distribuição da imunorreatividade à doublecortina no prosencéfalo de pombos adultos (Columba livia): avaliação dos efeitos de diferentes condições de alojamento
No full textTCC(graduação) - Universidade Federal de Santa Catarina. Centro de Ciências Biológicas. Biologia.A doublecortina (DCX) é uma proteína associada a microtúbulos crítica para a migração radial e tangencial de neurônios imaturos, tanto no cérebro em desenvolvimento quanto no adulto. No cérebro de mamíferos adultos neurônios recém formados no hipocampo e da zona subventricular (SVZ) são imurreativos à DCX (DCX+). Oito pombos (Columba livia, Columbiformes), entre 8 e 10 meses de idade e peso corporal de 380 a 420g, foram alojados em duas diferentes condições ambientais (enriquecida, n=4 e nãoenriquecida, n=4). Após um período de 40 dias os animais foram perfundidos (com solução sacarose 9,25% seguida de de 4% paraformaldeído em PBS 0,01 M) sob overdose de anestesia (Cetamina e Xilazina). Os cérebros foram removidos e seccionados em criótomo a uma expessura de 50um. Essas secções foram então submetidas a reações imunohistoquímicas (anticorpo policlonal de coelho Anit-DCX, Abcam, secundário anti-coelho biotinilado revelado pelo método ABC, Vector, reação colorimétrica com DAB, Sigma) para marcação da DCX. As secções telencefálicas de quatro animais do ambiente não-enriquecido foram observadas sob microscópio óptico e fotografadas para a descrição da distribuição total de células e fibras imunorreativas à DCX. Secções contendo o hipocampo de todos os animais dos dois grupos experimentais foram, da mesma forma, observadas e fotografadas e as células DCX+ hipocampais foram contadas. Constatamos que doublecortina é amplamente distribuída no telencéfalo de pombos adultos. Observamos células e fibras DCX+ na SVZ, hipocampo, estriado, hyperpallium apicale, arcopallium, mesopallium, nidopallium, área septal e bulbo olfativo. Pudemos descrever também as vias principais de migração celular no prosencéfalo desse animais. Além disso nossos dados indicam que, como em roedores, existe diferença estatisticamente significante no número de células DCX+ hipocampais entre os dois grupos experimentais
POR ENTRE AFETOS, SABERES, CONVERSAS E LUTAS EM TORNO DA DEFICIÊNCIA: ENTREVISTA COM LUCIANA FERRARI
No full textRESUMO: Essa entrevista buscou trazer (des)entendimentos acerca do termo deficiência a partir das vivências da Profa. Luciana Ferrari como pesquisadora das relações entre deficiência, linguagem e decolonialidade e como mãe da Lívia, uma adolescente com paralisia cerebral. As questões trazidas pela Profa. Lívia Fortes, professora e pesquisadora da área da Linguística Aplicada, mais especificamente sobre formação de professores, partiram de seu próprio processo de construção de sentidos sobre a deficiência, atravessado pela convivência com a Lívia e com a Luciana, de quem é amiga pessoal. Esperamos que as ideias aqui apresentadas e discutidas possam ensejar processos de interrupção do capacitismo tão comum em nossa sociedade.
PALAVRAS-CHAVE: Deficiência. Linguística aplicada. Capacitismo.ABSTRACT: This interview sought to bring understandings about the term disability based on the experiences of Prof. Luciana Ferrari as a researcher on the connections between disability, language and decoloniality and as mother of Lívia, a teenager with cerebral palsy. The questions raised by Prof. Lívia Fortes, professor and researcher in the field of Applied Linguistics, more specifically on teacher education, started from her own process of constructing meanings about disability, intertwined with her personal relationship with Lívia and Luciana, of whom she is a close friend. We hope that the ideas presented and discussed here can lead to processes of interrupting the ableism that is so common in our society.

Environmentally Friendly Lycopene Purification from Tomato Peel Waste: Enzymatic Assisted Aqueous Extraction.
No full textThe antioxidant and anticancer properties of lycopene make it an ideal component for daily food supplements.
For this reason this study investigated the possibility of extracting lycopene from tomato waste peels using a green chemistry protocol devoid of organic solvent. Cells are lysed thanks to a combination of pH changes and hydrolytic enzyme treatments.
The lycopene-containing chromoplasts are then precipitated by lowering the pH and isolated through a centrifugation step. At this stage the lycopene content of the isolated chromoplasts shows a 10-fold increase (3−5% w/w, dry basis) with respect to untreated tomato peels. A further improvement in lycopene concentration is obtained by a second enzymatic treatment using a protease cocktail. This catalytic step eliminates unwanted proteins, bound to the chromoplasts, but not essential for their stability.
The final product shows a lycopene content around 8−10% (w/w, dry basis), which represents a 30-fold increase with respect to the lycopene concentration of the untreated peels
Thermal stability improvement of duble colorant C-phycocyanin from Spirulina platensis for food industry applications.
No full textC-Phycocyanin (C-PC) is a blue pigment in cyanobacteria, rhodophytes and cryptophytes with potential use as a value-added food colorant. Its stability was studied by examining the thermal degradation reactions in a range of temperature (25-80 C) before and after the addition of selected edible preservatives. The natural protein crosslinker methylglyoxal does not stabilize significantly C-PC whereas addition of honey or high concentration of sugars greatly diminish the blue color degradation occurring when C-PC is exposed to high temperature. Data show that the sugar preservative effect on the C-PC blue color is related to the final concentration of sugar added rather than the type of sugar. For this reason the best preservative was found to be fructose, which is the most soluble sugar among those tested, at saturation concentration. Exploratory sterilization studies have been carried out with six blue/green fructose syrups made by mixing C-PC with the natural yellow pigment Carthamus tinctorius. Both after a "low temperature" and a "high temperature" sterilization procedure the syrups remain clear and maintain their bright color with only partial blue color degradation. After the sterilization process, the syrups were monitored for two months, in such observation period the loss of blue color is minimal

Access control is available according to both push and pull document distribution policies, and document updates are distributed through a combination of hash functions and digital signature techniques. The Author-X approach to distributed updates allows a user to verify a document's integrity without contacting the document server
Le lettere di Francesco Paolo Como a Ettore Ferrari.
No full textIn 1923 the sculptor Francesco Paolo Como (Taranto, 1888-Rome, 1973) wins the contest for the Monumento ai caduti in Taranto. As known, the realization of this work suffers many delays because of tension between the author and the various committees. Only in 1953, the last group, the Aquilifero, can be set up. The article analyses the sequence of events related to the monument through a series of missives between Como and his mentor Ettore Ferrari (Rome, 1845-1929). Through this correspondence is possible to write a clearer history of the monument and his author, explaining the reasons of Como’s anxiety, his relationship with Ferrari and his social role into the ‘fascistissima’ Taranto
Il Naxiǰewan di Luigi Villari.
No full textLuigi Villari’s book Fire and Sword in the Caucasus, published in London in 1906, is
widely quoted by the scholars who study the history of South Caucasus at the time
of the first Russian Revolution in 1905. After a short introduction about the interest-
ing figure of this author, the first part of the article will take into consideration Villari’s
peculiar attitude toward the Armenians. The larger part of the article will consider his
first-hand description of the massacres perpetrated by the Azeris (Tartars) in the region
of Nakhichevan. As a matter of fact, Luigi Villari’s testimony of the tragic events of 1905
is more interesting than ever to understand the origins of a contrast that continues—
even if in a deeply different situation—to stain with blood the relationship between Armenians and the South Caucasian Turks
