Imaginário e espacialidade vivida em narrativas quilombolas, Pimenteiras do Oeste – Rondônia, Brasil
Authors: Pinheiro Zairo Carlos da Silva , Sahr Cicilian Luiza Löwen 
Published: May 2016

Resumo Esse artigo busca discutir o imaginário na espacialidade vivida levando em conta a oralidade de sujeitos quilombolas. Para tanto, estuda-se o caso concreto de Pimenteiras do Oeste em Rondônia (RO) à luz das narrativas de seus quilombolas e também de teóricos da fenomenologia. Acredita-se que a reivindicação de um espaço quilombola, a Fazenda Santa Cruz, esteja sustentada tanto pelo imaginário social e pela espacialidade construída e reconstruída ao longo da história do grupo, como também - e principalmente - pelo imaginário social recente, tornado visível a partir da Constituição Federal de 1988. A pesquisa demonstra que a vontade de “ser quilombola” perpassa pelo imaginário de diferentes discursos, e que este imaginário se mescla com as espacialidades do grupo, tornando-os um dependente do outro.Palavras-chave: imaginário; espacialidades; narrativas; quilombolas; Rondônia. Abstract This article is discussing the function of imaginaries in lived spatialities, based on an investigation on the orality of quilombolas. As such, it is directed towards a case study in Pimenteiras do Oeste in Rondonia (Brazil), a place which is understood through the narratives of its quilombola population as well as through phenomenological methods. Its premises are that the claim for a quilombola space, in our case the Fazenda Santa Cruz, is based on a connection between social imaginary and its produced spatiality, on one hand grounded on a long-term lived experience of the group, and on the other referring to a more recent imaginary that is linked to the Federal Constitution of Brazil from 1988. Throughout the research it appears that the will to “be quilombola” is passing through the imaginary of several discourses, and that these imaginaries do mix within the lived spatialities of the group, turning each element dependent on the other.Keywords: imaginary; spatiality; narratives; quilombolas; Rondonia. ResumenEl presente artículo discute lo imaginario en la espacialidad vivida a la luz de la oralidad de sujetos quilombolas (cimarrones). El caso de Pimenteiras do Oeste, Rondônia, es estudiado a partir de las narrativas de los quilombolas a través del análisis de la fenomenología. La demanda de un espacio quilombola, la Hacienda Santa Cruz, es apoyada tanto por el imaginario social y la espacialidad construida y reconstruida a lo largo de la historia del grupo, pero también - sobre todo - por el imaginario social reciente, que se hizo visible desde la Constitución Federal de 1988. La investigación muestra que el deseo de "ser quilombola" está presente en los diferentes discursos, y éste imaginario está mezclado además, con la espacialidad del grupo estudiado, haciéndolos interdependientes.

Published: May 2016

Introduction Data from national registries have favored the use of cemented fixation in total hip replacement (THR) while other reports show no significant differences in implant survival between cemented and uncemented fixation using modern implants. It is important to investigate whether the method of fixation itself may affect patient-reported outcomes. Hence, this study sought to analyse if patient-reported outcomes measures (PROMs) differ depending on the type of fixation. Methods Data was used from the follow-up programme of the Swedish Hip Arthroplasty Register which comprises the EQ-5D, a visual analogue scale (VAS) on hip pain, as well as a VAS addressing satisfaction with the outcome of the hip replacement. 3,118 patients with uncemented THR due to primary osteoarthritis performed from 2002 to 2011 with complete 1-year follow-up were included in the study. A control group of patients with cemented THR (n = 3,118) were selected by matching on age, gender, Charnley class, and pre-operative health-related quality of life. Results After adjusting for age, gender, Charnley class, and baseline PROMs, multivariate linear regression analyses showed that uncemented fixation is associated with a larger improvement in EQ-5D index (B = 0.03, 95% CI 0.019, 0.041), EQ VAS (B = 2.58, 95% CI 1.65, 3.51), greater pain relief (B = -2.68, 95% CI -3.54, -1.82) and superior patient satisfaction (B = -2.56, 95% CI -3.52, -1.60) (all p<0.001). Discussions This study demonstrates that uncemented fixation is associated with better patient-reported outcomes. Factors unrelated to implant fixation, such as performance or selection bias, may also contribute to the difference.

Published: May 2016

Background Legg-Calvé-Perthes disease (LCPD) is the idiopathic avascular necrosis of the femoral head in childhood. The pathologic changes seen in the femoral head are likely a result of vascular factors. Blood neutrophil to lymphocyte (N/L) ratio is a simple marker of subclinical inflammation. This study aims to to analyse the predictive ability of N/L ratio for the prognosis in LCPD patients. Methods Patients who had been diagnosed as LCPD from 2008 to 2014 were investigated retrospectively and 40 LCPD patients (33 male and 7 female) and 25 healthy age and sex-matched children (controls) were included in the study. LCPD patients were divided into 2 groups according to expected prognosis (good prognosis expected Herring A and B patients as Group I and poor prognosis expected Herring B-C and C patients as Group II) and healthy children (control) were included in Group III. All the patients’ hematological markers were analysed. Results Mean age was 7.1 ± 2.0 years in group I (4.9-12 years), 8.3 ± 2.2 years (4-12.5 years) in group II and 7.8 ± 1.3 years (6-12 years) in group III. Mean values for Groups I, II and III for neutrophil to lymphocyte (N/L) ratio were 1.13 ± 0.65, 1.75 ± 0.95, 1.08 ± 0.37, respectively. The mean neutrophil to lymphocyte (N/L) ratio of Group II was higher than the other 2 groups (p = 0.003). Conclusions N/L ratio may give us information about the natural course of LCPD and may be used as independent predictor of prognosis in patients with LCPD.

Introduction Papillary thyroid cancer is a disease that has been associated with chronic inflammation. The purpose of this study is to measure the production of the proinflammatory cytokines IL-1β, IL-6 and IL-8 and neopterin, which is a novel biomarker for cellular immune response in papillary thyroid cancer. Materials and methods The serum IL-1β, IL-6, IL-8 and neopterin values of 31 papillary thyroid cancer patients undergoing bilateral total thyroidectomy were measured before and 20 days after surgery. The values were compared with those of 39 healthy controls. Results Serum IL-1β levels were similar across groups. IL-6 (p<0.001), IL-8 (p = 0.015) and neopterin levels (p = 0.002) were higher in presurgical samples and returned to normal following surgery. Conclusions The proinflammatory cytokines IL-6 and IL-8, but not IL-1β, were produced in greater amounts in papillary thyroid cancer. Serum neopterin seems to be a valid biological marker supporting the presence of papillary thyroid cancer.
Van casus-specifieke beleidsevaluatie naar systematische opbouw van kennis en ervaring

Van casus-specifieke beleidsevaluatie naar systematische opbouw van kennis en ervaring
Een lerende overheid heeft behoefte aan beleidsevaluaties die niet alleen van betekenis zijn voor het onderwerp waarop deze primair gericht zijn, maar ook bijdragen aan bredere, systematische opbouw van kennis en ervaring. Het interdepartementaal verbinden van expertise verruimt daarbij het zicht op factoren die het leren bevorderen of belemmeren.Een centrale vraag is of de door het beleid beoogde publieke belangen inderdaad bevorderd worden. Beleidsevaluatie moet dan niet alleen gericht zijn op effectiviteit en doelmatigheid ten aanzien van relatief gemakkelijk meetbare indicatoren, maar ook op lastig te kwantificeren essentiële waarden zoals subjectief welzijn, rechtvaardigheid en maatschappelijke aanvaardbaarheid. Het verdient aanbeveling kostbare evaluatie-energie te concentreren op belangrijke kwesties waarover vooraf discussie of onzekerheid bestaat.Uit een oogpunt van doelmatige beleidsvoorbereiding, en omdat de uitwerking van wetgeving en beleid ex post niet altijd eenvoudig is vast te stellen, is veel aandacht nodig voor ex ante evaluatie. Van onderzoek naar werkingsmechanismen van beleidsmaatregelen wordt in dit verband terecht veel verwacht.Er is sprake van een paradoxaal spanningsveld tussen verwetenschappelijking en politisering van beleid. Daarom is stevig verankerde, onafhankelijke en onpartijdige beleidsevaluatie onmisbaar. Hoge methodologische kwaliteit biedt extra houvast om deze functie geloofwaardig te kunnen vervullen.In het streven naar systematische opbouw van kennis en ervaring naast dossier-specifieke doelbereiking kan het helpen als evaluaties zowel een specifiek als een breder geldend algemeen deel bevatten. Belangrijk is ook te sturen op een evenwichtige evaluatieportfolio per beleidsterrein, met aandacht voor ex ante en ex post methoden, uiteenlopende waarden, en verschillende informatiebronnen. Naast best practices moet daarbij ook minder geslaagd beleid in beeld worden gebracht. Voor de bruikbaarheid van evaluaties voor de praktijk is goede vertegenwoordiging van het bottom-up perspectief noodzakelijk.Evaluatie van beleid vereist gedegen inbedding binnen de nationale kennisinfrastructuur, effectieve samenwerking met kennisinstellingen en het up-to-date houden van het evalueren zelf. Dat is cruciaal voor het evaluatievermogen van de lerende overheid.
A ten‐week biochemistry lab project studying wild‐type and mutant bacterial alkaline phosphatase
Authors: Witherow D. Scott 
Published: May 2016

AbstractThis work describes a 10‐week laboratory project studying wild‐type and mutant bacterial alkaline phosphatase, in which students purify, quantitate, and perform kinetic assays on wild‐type and selected mutants of the enzyme. Students also perform plasmid DNA purification, digestion, and gel analysis. In addition to simply learning important techniques, students acquire novel biochemical data in their kinetic analysis of mutant enzymes. The experiments are designed to build on students' work from week to week in a way that requires them to apply quantitative analysis and reasoning skills, reinforcing traditional textbook biochemical concepts. Students are assessed through lab reports focused on journal style writing, quantitative and conceptual question sheets, and traditional exams. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(6):555–564, 2016.

Published: May 2016

AbstractOn‐line high performance liquid chromatography (HPLC) coupled with three biochemical detection (BCD) methods was applied to evaluate bioactive components in Danshen injection. On‐line HPLC‐photo‐diode array–fluorescence detection based on the fluorogenic substrate 7‐acetoxy‐1‐methyl quinolinium iodide, was built to search acetylcholinesterase (AChE) inhibitors in Danshen injection. On‐line HPLC coupled with the scavenging assay of 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) and 2,2′‐azinobis (3‐ethylbenzothiazoline‐6‐sulfonic acid) (ABTS) free radicals was developed to screen antioxidants. The three active profiles were obviously different. Radical scavenging profiles revealed seven strong peaks in the chromatographic fingerprint possessing obvious free radical inhibition effects, while some minor peaks exhibited stronger AChE inhibition activities. The main radical scavengers and AChE inhibitors were identified by HPLC‐MS. Several unknown ingredients showing strong AChE inhibition activities needed further identification except protocatechuic aldehydrate, salvianolic acid H or I and lithospermic acid. The on‐line multiple on‐line HPLC‐BCD methods will provide powerful tools in the field of pharmacognosy for fast‐track identification of interesting and/or novel bioactive compounds.
