Nociones del espacio urbano. Cien años de inestabilidad: confluencia de lugares
Authors: Pérez Montás Eugenio
Published: March 2020

Reflexiones sobre el siglo XX tomadas de la semblanza de un profesor que viajaba a París todos los años y de un ensayo inédito que trata del efecto y retroactividad del Seminario de Arquitectura Latinoamericana 2015 (SAL). También de un artículo sobre la Plaza de la Cultura con motivo de su remodelación y su relación con la arquitectura del poder y el poder de la arquitectura. El Parque Mirador del Sur y la influencia de determinados libros y varios ensayos del autor, crean una secuencia que se inicia con comentarios de la época en que tuvieron lugar las dos guerras mundiales y sus protagonistas. Varias reflexiones relatan acontecimientos bélicos y el desarrollo de la arquitectura y las artes durante todo el siglo XX y las primeras décadas del siglo XXI. El texto se extiende sobre el concepto de vanguardia y la filosofía del espacio. ¿Qué es un lugar? ¿Qué es un sitio? ¿Qué es una utopía? ¿Cuál es la realidad urbana contemporánea?

Published: March 2020

A histological survey of the commercially edible mussels Mytilus platensis and M. chilensis from wild and cultivated populations along the coast of Patagonia, Argentina (42°00’ to 54°47’S), was carried out to determine their health status. Diagnostic results included 3 types of inflammatory responses (infiltrative, nodular, and encapsulation), disseminated neoplasia disease, 2 abnormal reproductive conditions (gonadal atresia and intersex), prokaryotic inclusions, protozoans, and metazoans. Pathogen prevalence and infection intensity among mussels of different sampling sites and between those of wild and cultivated populations were compared. Inflammatory responses were recorded in all mussels from all sites, while disseminated neoplasia only occurred in the most southern cultivated M. chilensis. Intracellular prokaryotic inclusions were broadly distributed in the mussels from both northern and southern Patagonian coasts. Ciliates showed the highest prevalence among wild mussels from the colder waters of Bahía Brown. Turbellaria were recorded at higher prevalence in cultured mussels (41.7%), and trematode metacercariae occurred exclusively in intertidal wild mussels. None of the parasites found appears to be a problem to the fishery or farming, although disseminated neoplasia should be monitored. In addition, we found that mytilid species coexisting with M. platensis (Aulacomya atra and Perumytilus purpuratus) at one location shared the same pathological conditions and parasites, which differed from those of M. platensis at a distant locality. These results suggest that pathological conditions and parasites were influenced more by ecological habitat factors than by the species of mussels present, based on similar parasite assemblages found among closely related mytilid hosts in the same geographical area.

The aim of our study was to investigate mechanism of action of endothelins 1, 2 and 3 on spontaneous activity, tone and intraluminal pressure of human ureter. Both longitudinal tension and intraluminal pressure were recorded from the isolated segments of proximal human ureter. Endothelins 1, 2 and 3 (5.35x10-11 M - 5.05x10-8 M) produced concentration-dependent tonic contraction and sustained increase in intraluminal pressure of isolated preparations of human ureter. Endothelins 1 and 3 produced also concentration-dependent inhibition of spontaneous, phasic contractions of the isolated preparations. Selective antagonist of ETA receptors BQ123 and selective antagonist of ETB receptors BQ788 produced significant inhibition of endothelin-1-induced tonic contraction (pA2=8.80 and 6.55, respectively) and increase in intraluminal pressure (pA2=8.68 and 7.02, respectively), while they did not affect endothelin-1-induced inhibition of spontaneous activity. Endothelin 1 produces increase in tone and intraluminal pressure of isolated human ureter acting on both ETA and ETB receptors, the first one being functionally more important. Only endothelins 1 and 3 inhibit spontaneous, phasic activity of human ureter, but this effect was not blocked by selective antagonists of ETA and ETB receptors.

Published: March 2020

The objective of this study was to find out the implication of QRS duration in dogs with rapid pacing-induced heart failure. Sixteen Beagle dogs were implanted with transvenous cardiac pacemakers and underwent rapid right ventricular pacing for 3 weeks at 260 bpm to induce heart failure. Dogs were divided into two groups according to the QRS duration: 9 with normal QRS duration (<100 ms) and 7 with prolonged QRS duration (≥100 ms). Cardiac systolic function and size was analyzed by real time 3-dimensional echocardiography and left ventricular dyssynchrony was assessed by speckle tracking strain imaging. Congestive heart failure developed 3 weeks after rapid right ventricular pacing. Dogs with prolonged QRS duration showed more extensive radial strain and circumferential strain dyssynchrony than dogs with normal QRS duration. At the end of 4-week recovery, greater improvement of left ventricular ejection fraction and left ventricular end-systolic volume was detected in dogs with normal QRS duration. The findings suggested that left ventricular dyssynchrony, indicated by a prolonged QRS duration, predicted an unsatisfying recovery in dogs with rapid pacing-induced heart failure. QRS duration had the potential to be a prognostic indicator for dogs with heart failure.

For better understanding of pathophysiological processes leading to increased retention of sodium as a consequence of hyperlipidemia, the properties of renal Na,K-ATPase, a key enzyme involved in maintaining sodium homeostasis in the organism, were studied. Enzyme kinetics of renal Na,K-ATPase were used for characterization of ATP- and Na+-binding sites after administration of fish oil (FO) (30 mg·day-1) or atorvastatin (0.5 mg·100 g-1·day-1) to healthy Wistar rats and rats with hereditary hypertriglyceridemia of both genders. Untreated healthy Wistar and also hypertriglyceridemic female rats revealed higher Na,K-ATPase activity as compared to respective untreated male groups. Hypertriglyceridemia itself was accompanied with higher Na,K-ATPase activity in both genders. Fish oil improved the enzyme affinity to ATP and Na+, as indicated by lowered values of Km and KNa in Wistar female rats. In Wistar male rats FO deteriorated the enzyme in the vicinity of the Na+-binding site as revealed from the increased KNa value. In hypertriglyceridemic rats FO induced a significant effect only in females in the vicinity of the sodium binding sites resulting in improved affinity as documented by the lower value of KNa. Atorvastatin aggravated the properties of Na,K-ATPase in both genders of Wistar rats. In hypertriglyceridemic rats protection of Na,K-ATPase was observed, but this effect was bound to females only. Both treatments protected renal Na,K-ATPase in a gender specific mode, resulting probably in improved extrusion of excessive intracellular sodium out of the cell affecting thus the retention of sodium in hHTG females only.
Comparison of New ELISA Method With Established SDS-PAGE Method for Determination of Muscle Myosin Heavy Chain Isoforms
Authors: ŘÍČNÝ J. , SOUKUP T.
Published: March 2020

We developed a new method for the quantitative determination of myosin heavy chain (MyHC) isoforms taking advantage of immunochemical differences and based on the ELISA principle. In the present paper we compare analysis of MyHC isoforms using the SDS-PAGE and the ELISA methods in the same samples of adult female inbred Lewis strain euthyroid, hyperthyroid and hypothyroid rats. In all thyroid states, the same composition and corresponding changes of MyHC isoforms were determined using both methodological approaches in the slow soleus and the fast extensor digitorum longus muscles. Our results showed that ELISA can be used for a “semi-quantitative” or “comparative” measurement of MyHC isoforms in multiple muscle samples, but that it is neither more exact nor faster compared to SDS-PAGE.

Published: March 2020

Increased colonic Cl- secretion was supposed to be a causative factor of diarrhea in inflammatory bowel diseases. Surprisingly, hyporesponsiveness to Cl- secretagogues was later described in inflamed colon. Our aim was to evaluate changes in secretory responses to cholinergic agonist carbachol in distal and proximal colon during colitis development, regarding secretory activity of enteric nervous system (ENS) and prostaglandins. Increased responsiveness to carbachol was observed in both distal and proximal colon after 3 days of 2 % dextran sodium sulfate (DSS) administration. It was measured in the presence of mucosal Ba2+ to emphasize Cl- secretion. The described increase was abolished by combined inhibitory effect of tetrodotoxin (TTX) and indomethacin. Indomethacin also significantly reduced TTX-sensitive current. On the 7th day of colitis development responsiveness to carbachol decreased in distal colon (compared to untreated mice), but did not change in proximal colon. TTX-sensitive current did not change during colitis development, but indomethacin-sensitive current was significantly increased the 7th day. Decreased and deformed current responses to serosal Ba2+ were observed during colitis induction, but only in proximal colon. We conclude that besides inhibitory effect of DSS on distal colon responsiveness, there is an early stimulatory effect that manifests in both distal and proximal colon.

Foreign language ability is one of inevitable prerequisites for tourists guide in serving foreign tourists. The most needed abilities is speaking competence, particularly in serving tourists for transfer in, check in dan transfer out. This research is intended to investigate speaking language abilities of tourists’ guides in Puncak area, particularly their ability in speaking of Arabic language. Based on the qualitative approach, this research uses partisipative observation and interview of key informants, consist of 4 tourists guides within this area, 5 members of tourists guide association, and 2 owners of tour and travel bureau.  Findings are that tourist guides learn speaking in Arabic language by themselves, building some interactions with Arab tourists or Arab inhabitants, or by learning Arabic in formal or semi informal school. Furthermore, some tourist guides learned Arabic (mostly local dialect) in one of Arabic nations while they worked there, and therefore they are preferred both by travel agencies and Arab tourists. Tourists guide who are only able in speaking Arabic language will do transfer in, check in, and transfer out processes by using Arabic language, whilst tourists guide with ability in speaking of Arabic and another foreign language (English) will prefer the most language they able to speak and will do switch code whenever needed.

Down-hole permeability prediction – a chemometric wire-line log feasibility study from a North Sea chalk well
Authors: Esbensen Kim H. , Schovsbo Niels H. , Kristensen Lars
Published: March 2020

Permeability in chalk depends primarily on porosity but also on other factors such as clay and quartz content, and can theoretically be described by the Kozeny equation using empirically determined constants (Mortensen et al. 1998; Røgen & Fabricius 2002). Recent attempts to predict permeability from wire-line logs have shown that compressional velocity within operative chalk units, defined by specific surface and hydraulic properties established from stratigraphy and core plugs, can provide excellent well permeability predictions (Alam et al. 2011). High-quality predictions depend on a solid knowledge of a multitude of parameters of the relevant ‘operative rock types’. The more detailed this a priori knowledge is, the better predictions can be achieved. But this approach may, or may not, be fast enough for wellsite operations or when core data are lacking. In this study, we illustrate a situation for direct permeability prediction if only well-site, wire-line logs are available.
The ammonites of the Middle Jurassic Cranocephalites beds of East Greenland
Authors: Callomon John H. , Alsen Peter , Surlyk Finn
Published: March 2020

Thick successions of marine Middle Jurassic deposits rich in ammonites occur in the Jameson Land Basin in central East Greenland. The fauna of the so-called Cranocephalites beds of this basin, comprising the Borealis–Pompeckji Standard Zones, was until now largely represented by a single collection. This was made by T.M. Harris during a 1927 excursion up the valley of Ugleelv to Katedralen, the type area of Cranocephalites pompeckji, which is the oldest named species of this genus. Revisits to this area in 1994 and 1996 by JHC resulted in a large bed-by-bed collection of Cranocephalites. The number of faunal horizons that could be distinguished grew from the nine previously recognised to thirty-four today. The zonal stratigraphy of the Cranocephalites beds encompasses the Borealis, Indistinctus and Pompeckji Standard Zones. The Pompeckji Zone is subdivided into four new subzones, reflecting four successive basic morphologies of Cranocephalites that should be recognisable more widely and are thus useful for subzonal correlations. The detailed zonation that serves as the secondary standard zonation for the Boreal Province in the Middle Jurassic is thus highly improved. The biostratigraphic resolution obtained here is near the achievable limits. It allows a high-resolution study of the evolution of the ammonites which on this timescale appears to be continuous. Three new species are described: Cranocephalites carolae sp. nov., Cranocephalites intermissus sp. nov. and Cranocephalites episcopalis sp. nov. An additional new species, Cranocephalites tvaerdalensis sp. nov., is described in the appendix by P. Alsen based on collections from Tværdal on Geographical Society Ø, North-East Greenland. This species is also recorded in Jameson Land.
Professores em greve no Paraná: quais são as concepções dos futuros trabalhadores da educação?
Authors: Rodrigues Ana Paula Aires , Gomes Marco Antonio de Oliveira
Published: March 2020

O tema desta pesquisa foi o movimento de greve de 2015 da educação paranaense, a partir das concepções dos acadêmicos do curso de Pedagogia de uma Universidade pública do norte do Paraná. Partiu-se do seguinte problema: “Quais são as concepções dos acadêmicos do curso de Pedagogia da modalidade presencial, acerca da greve que ocorreu em 2015?”. Pretendia-se investigar o que esses discentes, que são potencialmente trabalhadores da educação, pensam a respeito da greve e suas implicações. O estudo foi desenvolvido apresentando como aporte teórico o Materialismo Histórico, fundado por Karl Marx, que serve de base para inúmeras análises científicas nas Ciências Humanas. Tratou-se de um estudo de campo, de caráter exploratório. Com vistas ao problema proposto considerou-se que a técnica mais apropriada era a interrogação, para isso foram definidos os seguintes instrumentos de coleta de informações: aplicação de questionários e entrevistas semiestruturadas, a amostra envolveu 18 discentes. Os resultados da investigação indicam que, de maneira geral, existe um posicionamento favorável à greve, porém, com algumas ressalvas. Além disso, os acadêmicos demostraram concepções românticas e maniqueístas do movimento. Conclui-se, com o estudo, que a maioria dos futuros trabalhadores da educação desconhecem sua própria condição de classe, possuem conhecimento incipiente em relação ao tema, bem como, demonstraram certa ausência de memória histórica. Contudo, a partir da pesquisa, verificou-se que o movimento de greve se apresentou como fator educativo, já que possibilitou contato direto ou indireto com outras questões que extrapolam as disciplinas curriculares do Curso em questão.

La relocalización de las estructuras sociales informales denominadas “Campamentos”, en la actualidad se presentan como una problemática de primer orden; si bien, estos asentamientos urbanos responden a estructuras transitorias o temporales, han forjado una problemática urbana de complejidad frente a la planificación territorial del tejido de la ciudad por parte de actores formales. Es un hecho que, paralelo a la existencia de la ciudad construida a partir de actores institucionales formales, inherentemente han surgido, de manera espontánea, asentamientos de origen irregular al interior de la ciudad; es por ello que este estudio se articula con base en la relocalización de campamentos en la comuna de La Pintana en Chile, a través de un análisis basado en un modelamiento que recoge variables y genera un modelamiento a través del software Arcgis 10.3.

Characterization of fatty acid based nanostructured lipid carrier (NLC) and their sustained release properties
Authors: Yew Han-Choi , Misran Misni
Published: March 2020

Nanostructured lipid carrier (NLC) is a second generation lipid nanoparticle formed by blends of solid and liquid lipids through hot homogenization technique. In this study, arachidic acid (C20) and erucic acid (C22:1) were used as solid lipids while oleic acid as liquid lipid in the preparation of NLC. Five types of NLC were prepared by varying the amount of oleic acid (C18:1) with respect to arachidic acid while maintaining the amount of erucic acid. Physical stability of the prepared NLC was characterized by its size and zeta potential for a period of 28 days. The results showed that the size of NLCs were between 200 to 260 nm with zeta potential of -55 to -40 mV. Differential scanning calorimetry (DSC) data showed that presence of oleic acid reduces the crystallinity of nanoparticle. Apart from that, depending on the compositions, the morphology of NLC examined under transmission electron microscopy’s (TEM) was round to elongate in shape. Then, active ingredients of ascorbic acid, caffeine and lidocaine with varied hydrophilicity were then loaded into the NLC. Lidocaine has an encapsulation efficiency of nearly 78% while caffeine reaches 43%. Surprisingly, ascorbic acid which is hydrophilic gave a comparative amount of encapsulation efficiency as caffeine at low concentration. This might relate to attraction between opposite charge of NLC and ascorbic acid. When the active ingredients loaded NLC was subjected to in vitro release, the active ingredients’ release profile suggested that NLC exhibit sustained release properties whereby the rate of release is concentration dependent.

Moisturizers are topically applied agent which increasing moisture content in the skin to maintain skin integrity and youthful appearance. L-brand soothing gel (Tested gel) was developed for skin hydration. The objective of this study is to evaluate the benefits of daily usage of Tested gel amongst healthy young adults. This study also aimed to assess whether storage temperature may affect the efficacy of Tested gel. Changes in moisture content and texture index of the skin where the product was applied over a period of 8 days were assessed using non-invasive devices to measure the skin’s bioelectric impedance. Our results indicate that application of Tested gel produces a hydrating effect characterized by a significant increment in skin moisture and smoothness. There was no association found between storage temperature and efficacy of gel. The hydration effect of Tested gel diminishes gradually after application, but the hydration effect is cumulative upon daily usage for healthy young adults.
