Littera Scripta Manet: formas y funciones del archivo en el Imperio de los Austrias. Simancas, Roma, Quito y Cuenca (Estudios)

El artículo explora el papel de los archivos en el Imperio de los Austrias, durante la edad protomoderna, en ambos lados del Atlántico. Con ese propósito se analizan las diferentes tareas que incumbían a los archivos en el siglo XVI y XVII. Se examinan el archivo de la ciudad de Cuenca (actual Ecuador) en el ámbito municipal, el de la Audiencia de Quito en el ámbito regional, el archivo de Simancas (Castilla) en el nivel real y, por último, el archivo en la embajada española en Roma. También se ofrecen reflexiones sobre el carácter y las particularidades de los repositorios documentales, prestando especial atención a la escritura como medio de gobierno.

User's manual

'Typeform dialogues', as originally planned for publication, was an interactive CD-based screen interface presenting a comparative survey of typeform history and description. The CD was to be held inside a printed book that included two essays and a User’s Manual. Although 'Typeform dialogues' (CD+book) was not completed as planned, a PDF file was published containing the User’s Manual, together with background information about the interface and the project it was part of. The User's Manual presents all interface sections and features (using screen grabs) and explains their editorial rationale, design, and function.

In vitro tests to establish LC(50) and discriminating concentrations for fipronil against Rhipicephalus (Boophilus) microplus (Acari: Ixodidae) and their standardization

Laboratory test was carried out on larvae and adults of the cattle tick, Rhipicephalus (Boophilus) microplus, to determine fipronil toxicity. Adult immersion test (AIT, N = 26), larval immersion test (LIT, N = 71) and larval packet test (LPT, N = 41) were standardized using susceptible strain (Mozo). Dose-response curves were compared with a fipronil resistant strain. Four variables were analyzed from AIT results: mortality, weight of eggs on day 7 and on day 14, index of fertility, and index of fecundity. For larval test, dose mortality curves were analyzed. In spite of the high LC(50) variability, all variables determined for AIT were appropriate to discriminate both strains. AIT and LIT had more sensitivity than LPT, with larger resistance factors. It was used two times LC(99.9) as discriminating doses (DCs) following FAO suggestion. For mortality by AIT, LIT and LPT the DCs were estimated: 4.98 ppm, 7.64 ppm and 2365.8 ppm, respectively, for Mozo strain. DCs mortality values estimated for resistant strain by AIT, LIT and LPT were: 6.96 x 10(5) ppm, 343.26 ppm and 5.7 x 10(3) ppm, respectively and their respective resistant factors were: 202.4, 5.36 and 1.52. Protocols for AIT, LIT and LPT have been presented in this paper. (C) 2009 Elsevier B.V. All rights reserved.

Dyslipidaemia in rural Australia : the evidence treatment gaps

Aims & rationale/Objectives : Hypercholesterolaemia accounts for 11.6% of total deaths and 6.2% of the disability burden for the Australian population.1 This paper reports population lipid profiles for three rural Australian populations, and assesses evidence-treatment gaps against the most recent (2005-2007) Australian guidelines.

Methods : Three population surveys were undertaken in the Greater Green Triangle. 3,320 adults aged 25-74 yrs were randomly selected using age/gender stratified electoral roll samples and of these 1563 subjects participated in the survey. Anthropometric, clinical and self-administered questionnaire data relating to chronic disease risk were collected in accordance with the WHO MONICA protocol.2 A detailed investigation of dyslipidaemia was included.

Principal findings : All required data was available for 1255 participants. Age-standardised mean total cholesterol (TC), triglycerides, LDL cholesterol and HDL cholesterol concentrations were 5.36 mmol/l, 1.42 mmol/l, 3.23 mmol/l and 1.48 mmol/l, respectively. Amongst those taking lipid-lowering medication, just 11% categorised as secondary prevention/diabetes, and 39% as primary prevention, achieved all lipid targets. In the 20% of untreated participants at high risk of a primary cardiovascular event, 26% were aware of their hypercholesterolaemia and just 2% achieved all lipid targets (2.8% achieved TC?5.5 mmol, 8.5% achieved LDL<3.5 mmol/l). 11.2% of the overall population used lipid-lowering medication (95% was statin monotherapy).

Implications : Most adults do not achieve their target lipid profile. This paper identifies the subpopulations and lipid components which need to be targeted for future interventions. It also identifies substantial evidence-treatment gaps which should be addressed to help improve lipid profiles at a population level.

Comparação da atividade anti-histamínica da clemastina e da pirilamina em íleo de Cavia porcelus (cobaio)

O presente trabalho teve como objetivo comparar fármacos utilizados como antihistamínicos na terapêutica de patologias alérgicas em pequenos animais. O modelo empregado foi órgão isolado in vitro (íleo de Cavia porcelus), o qual permitiu avaliar as variáveis farmacológicas DE50, Emáx, pD2, pD’2 e pA2. Comparamos as ações produzidas em curvas concentração-efeito para histamina e acetilcolina frente a diferentes concentrações de clemastina e pirilamina. Difenidramina foi empregada como controle. Os resultados permitiram confirmar que os dois fármacos atuaram efetivamente como antihistamínicos no íleo isolado de Cavia porcelus. O principal efeito foi de antagonismo competitivo, porém, em concentrações maiores, apresentaram efeito não-competitivo e perderam a especificidade aos receptores da histamina. A clemastina com pA2 de 8,63 foi 10 vezes mais potente do que a pirilamina (pA2 = 7,61) como anti-histamínico, mas também apresentou significativo (P<0,05; ANOVA, Bonferroni) efeito anticolinérgico, o qual não foi observado com a pirilamina. Entretanto, em concentrações mais elevadas, ambos apresentaram efeito anticolinérgico por mecanismo não-competitivo: clemastina a partir de 10-7 mol/L e pirilamina com 10-5 mol/L, resultando em pD’2 de 5,66 e 5,36; respectivamente. Da comparação com difenidramina, concluiu-se que a clemastina foi cerca de 10 vezes mais potente no efeito competitivo enquanto a pirilamina foi menos potente. Quanto ao componente não-competitivo, a clemastina foi mais eficaz que a difenidramina enquanto a pirilamina foi menos eficaz. Se os efeitos obtidos com a clemastina e pirilamina no íleo isolado também se observarem quando empregados na terapêutica, in vivo, é de se esperar que a clemastina apresente mais efeitos adversos (anticolinérgicos) do que a pirilamina.

Isolamento de uma quitinase extraída do cefalotórax do camarão marinho Litopenaeus schmitti (BURKENROAD, 1936) : avaliação de suas atividades antimicrobiana e larvicida

Chitinases are enzymes involved in degradation of chitin and are present in a range of organisms, including those that do not contain chitin, such as bacteria, viruses, plants and animals, and play important physiological and ecological roles. Chitin is hydrolyzed by a chitinolytic system classified as: endo-chitinases, exo-chitinases and N-acetyl-b-D-glucosaminidases. In this study a Litochitinase1 extracted from the cephalotorax of the shrimp Litopenaeus Schmitt was purified 987.32 times using ionexchange chromatography DEAE-Biogel and molecular exclusion Sephacryl S-200. These enzyme presented a molecular mass of about 28.5 kDa. The results, after kinetic assay with the Litochitinase1 using as substrate p-nitrophenyl-N-acetyl-b-Dglucosaminideo, showed apparent Km of 0.51 mM, optimal activity at pH ranging from 5.0 to 6.0, optimum temperature at 55°C and stability when pre-incubated at temperatures of 25, 37, 45, 50 and 55°C. The enzyme showed a range of stability at pH 4.0 to 5.5. HgCl2 inhibited Litochitinase1 while MgCl2 enhances its activity. Antimicrobial tests showed that Litochitinase1 present activity against gram-negative bacterium Escherichia coli in the 800 μg/mL concentration. The larvicidal activity against Aedes aegypti was investigated using crude extracts, F-III (50-80%) and Litochitinase1 at 24 and 48 hours. The results showed larvicidal activity in all these samples with EC50 values of 6.59 mg/mL for crude extract, 5.36 mg/mL for F-III and 0.71 mg/mL for Litochitinase1 at 24 hours and 3.22 and 0.49 mg/mL for the F-III and Litochitinase1 at 48 hours, respectively. Other experiments confirmed the presence of chitin in the midgut of Aedes aegypti larvae, which may be suffering the action of Litochitinase1 killing the larvae, but also the absence of contaminating proteins as serine proteinase inhibitors and lectins in the crude extract, F-III and Litochitinase1, indicating that the death of the larvae is by action of the Litochitinase1. We also observed that the enzymes extracted from intestinal homogenate of the larvae no have activity on Litochitinase1. These results indicate that the enzyme can be used as an alternative to control of infections caused by Escherichia coli and reducing the infestation of the mosquito vector of dengue.

Composição química e rendimento da carne ovina in natura e assada

Utilizou-se o músculo Triceps brachii de cordeiros não castrados ½ Ile de France ½ Santa Inês terminados em confinamento para a realização das análises físico-químicas. Foram determinados: a umidade, a proteína, a gordura, as cinzas e os carboidratos da carne, in natura e assada, destes animais, assim como o rendimento desta carne, após o processo de cocção. A carne assada apresentou valores maiores de gordura e proteína (7,49 e 33,67%) em comparação com a carne in natura (5,36 e 18,85%), respectivamente. Os percentuais de cinzas e carboidratos não foram influenciados pelos tratamentos estudados, porém para os valores de umidade, a carne in natura obteve valores superiores ao da carne assada, 74,05 e 57,02%, respectivamente. A carne assada teve perdas durante o seu preparo por evaporação, por gotejamento e por cocção de 33,20, 1,36 e 35,20%, respectivamente. Concluiu-se que a carne assada apresenta valor nutricional mais elevado que a carne in natura, para os teores de gordura e proteína, pelo fato da carne in natura apresentar maior valor de umidade em relação à assada, ocasionando assim a concentração de gordura e de proteína na carne assada. O preparo da carne ocasionou perdas por cocção de 35,20%, por gotejamento e evaporação.

The Influence of Cutting Speed and Cutting Initiation Location in Specimen Preparation for the Microtensile Bond Strength Test

Purpose: This study evaluated the effect of cutting initiation location and cutting speed on the bond strength between resin cement and feldspathic ceramic.Materials and Methods: Thirty-six blocks (6.4 x 6.4 x 4.8 mm) of ceramic (Vita VM7) were produced. The ceramic surfaces were etched with 10% hydrofluoric acid gel for 60 s and then silanized. Each ceramic block was placed in a silicon mold with the treated surface exposed. A resin cement (Variolink II) was injected into the mold over the treated surface and polymerized. The resin cement-ceramic blocks were divided into two groups according to experimental conditions: a) cutting initiation location - resin cement, ceramic and interface; and b) cutting speed - 10,000, 15,000, and 20,000 rpm. The blocks were sectioned to achieve non-trimmed bar specimens. The microtensile test was performed in a universal testing machine (1 mm/min). The failure modes were examined using an optical light microscope and SEM. Bond strength results were analyzed using one-way ANOVA and Tukey's test (alpha = 0.05).Results: Significant influences of cutting speed and initiation location on bond strength (p < 0.05) were observed. The highest mean was achieved for specimens cut at 15,000 rpm at the interface (15.12 +/- 5.36 MPa). The lowest means were obtained for specimens cut at the highest cutting speed in resin cement (8.50 +/- 3.27 MPa), and cut at the lowest cutting speed in ceramic (8.60 +/- 2.65MPa). All groups showed mainly mixed failure (75% to 100%).Conclusion: The cutting speed and initiation location are important factors that should be considered during specimen preparation for microtensile bond strength testing, as both may influence the bond strength results.

Condições associadas ao grau de satisfação com a vida entre a população de idosos

OBJECTIVE: As a result of overall growing population's life expectancy, it has become increasingly important to ensure not only that the elderly have greater longevity but also happiness and life satisfaction. The objective of the study was to describe factors associated with life satisfaction among elderly people.METHODS: Three hundred and sixty-five older persons, selected by means of random stratified proportional sampling, were interviewed in 2003. The instrument used was a combination of Flanagan and Nahas questionnaires and WHOQOL-100. There were added questions concerning physical activity extracted from International Physical Activity Questionnaire, questions regarding reported morbidity and emotional assessment, sociodemographic condition and an open question. The level of life satisfaction was measured using a scale from one to seven by means of visual recognition. Hierarchical logistic regression analysis was performed including life satisfaction as a dependent variable and those included the final questionnaire, in blocks, as independent variables.RESULTS: Most elderly were generally rather satisfied with life as well as with specific aspects. The level of life satisfaction was associated with: comfort at home (OR=11.82; 95% Cl: 3.27; 42.63); appraising leisure as quality of life (OR=3.82; 95% Cl: 2.28; 6.39); waking up feeling well in the morning (OR=2.80; 95% Cl: 1.47; 5.36); not reporting loneliness (OR=2.68; 95% Cl: 1.54; 4.65); having three or more daily meals (OR=2.63; 95% Cl: 1.75; 5.90) and not reporting Diabetes Mellitus (OR-2.63; 95% Cl: 1.3 1; 5.27).CONCLUSIONS: Most elderly in the study were satisfied with life and their satisfaction was associated with situations related to being well and not being diabetic.

A note on carcass characteristics of rabbits fed on a restricted system

Thirty four 65 days old New Zealand White female rabbits. weighting 1900 +/- 40 g, were separated in 3 groups and caged individually. One group was slaughtered when 70 days old (reference group, n=14). The second group was slaughtered 50 days later after ad libitum feeding (n = 6), and the third group was slaughtered also when 120 days old, but after restricted feeding since 70 days old i.e. 50% of the spontaneous feed intake of the 65-70 days period (restricted group n=14). Whole carcass weight and carcass cuts weights were measured after 24 hours storage at +4 degrees C. For each of the 3 groups in the previous order, slaughter live weight was 1992 - 2988 and 1887g; Chilled carcass percentage were 47.9 - 51.0 and 50.1. Feed restriction decreased the loin proportion of the carcass lower than that of the reference group (27.0 - 26.1 and 22.8% for the 3 groups in the same order) but increased the posterior limbs proportion (36.5 - 36.6 and 40.1).
