Abstract.
The secondary hyperparathyroidism that develops in rats with chronic renal insufficiency (CRI) can be totally prevented by activation of the parathyroid Ca2+ receptor with a calcimimetic compound, when treatment is initiated before parathyroid cell hyperplasia and increased circulating parathyroid hormone levels develop. In clinical practice, however, secondary hyperparathyroidism is usually manifest by the time CRI is diagnosed. This study examined the effects of daily oral gavage or continuous subcutaneous infusion for 8 wk of the calcimimetic NPS R-568 on the progression of established mild or moderate-to-severe secondary hyperparathyroidism in rats with CRI induced by 5/6 nephrectomy. Both oral and infused NPS R-568 completely prevented further hyperplasia but did not reduce total parathyroid cell number below that present at the initiation of treatment. This prevention of cellular proliferation occurred despite increases in plasma phosphate and decreases in Ca2+ and 1,25-dihydroxyvitamin D levels, and supports the view that the Ca2+ receptor is the dominant regulator of parathyroid cell hyperplasia in addition to parathyroid hormone secretion. The clinical implications of these findings suggest that controlling Ca2+ receptor activity with calcimimetic compounds could be sufficient to manage secondary hyperparathyroidism in CRI.

Abstract.
Over a 9-yr period, heart transplantation was performed in 200 patients at Sahlgrenska University Hospital. Of these 200 patients, 151 were followed for 1 to 9 yr with regard to renal function, hemodynamics, cyclosporin A concentrations, and complications. Patients with a preoperative serum creatinine >130 μmol/L received inotropic drugs to test for reversibility of renal dysfunction. The end point was graft failure. The average preoperative GFR of 66 ± 17 ml/min per 1.73 m2 declined to 52 ± 19, 44 ± 16, and 37 ± 17 at 1, 5, and 9 yr after heart transplantation, respectively. Altogether, the average GFR declined by 44%. There was no significant correlation between the preoperative GFR and postoperative renal function or survival. Recipient age was a predictor of renal function during the entire follow-up. Severe renal dysfunction (GFR <20 ml/min per 1.73 m2) developed in 20% of the patients, which was predicted by the recipient age at transplantation together with the GFR 1 yr after transplantation. A nomogram that shows the risk of developing severe renal dysfunction after heart transplantation is presented. Cyclosporin A concentrations and treatment with statins, calcium channel blockers, or angiotensin-converting enzyme inhibitors did not correlate with the evolution of renal function. Patients with a preoperative depressed renal function who improved on inotropic treatment seemed to have a poorer outcome compared with the other study patients.

Introducción: El correcto funcionamiento del eje hipotálamo-hipófisis-tiroides es indispensable para el crecimiento y desarrollo embrionario-fetal, al intervenir en la diferenciación de los tejidos, el desarrollo cerebral y somático, la maduración ósea y la regulación del metabolismo. El paso de las hormonas tiroideas maternas al feto a través de la placenta depende de transportadores transmembrana, enzimas desyodinasas (DIO2 y DIO3) y proteínas transportadoras (TTR). Objetivo: Identificar las zonas de expresión de DIO3 y TTR en la placenta de ratón Mus musculus E10.5, E12.5, E14.5. Métodos: La estructura placentaria y expresión de DIO3 y TTR fueron evaluadas con técnicas histoquímicas e inmunofluorescencia. Resultados: Desde E10.5 se encontraron las tres zonas placentarias, laberinto, zona de unión y decidua. En E12.5 se observó la conformación placentaria definitiva. DIO3 y TTR fueron detectadas en los tres estadios, con predominio en la zona del laberinto. Conclusión: DIO3 y TTR se expresan a lo largo del establecimiento y maduración de la placenta de ratón. El biomodelo murino es una herramienta útil para el estudio del transporte placentario de hormonas tiroideas desde la circulación materna a la fetal.
‘Cadáveres Amados’: Martyrs, Memory, and Cuban National Symbols
Authors: Wade Bethany M. 
Published: May 2021

Abstract
On November 27th, 1871, eight young medical students were marched into a public plaza in Havana and shot by Spanish authorities. On the first anniversary of their death, the exiled José Martí used their execution to denounce Spanish rule in Cuba, and to legitimize the violent struggle for Cuban Independence. The executed students became martyrs to Cuban nationalism. Since then, their execution at the hands of tyrants has been repeatedly repurposed in revolutionary periods in Cuban history. This article engages with the work of Maurice Halbwachs, Jan Assmann, and Pierre Nora to reflect on the process of collective and cultural memory formation and reformation. It considers the factors that contributed to the transformation of the execution of these students from a singular tragedy, among a wider field of atrocity, into a defining moment in Cuban identity. Further, drawing on works by Jay Winter, Robin Cohen, and Ron Eyerman, this article interrogates the role of individuals and groups in this process. Over one hundred and fifty years, members of exile communities, moral witnesses, student protesters, and revolutionary leaders used the memory of these martyrs to contest authoritarian rule, hoping to advance their vision of a Cuba that could be. Driven by changing political imperatives, the memory of the students altered to reflect new collective priorities. This case study shows change and continuity in cultural memory. Tracing the evolution of this narrative from the Cuban War of Independence, through the rule of dictators, Castro’s revolutionary war, and the following socialist era, this article concludes by asking how their memory is being—once again—transformed today. With a focus on the construction and use of public monuments and memorials, but incorporating literature, images, annual marches, and films, this article argues that the public memory of their deaths altered in different periods to invoke a revolutionary vision of Cuban national identity battered by a century and a half of instability.
Postmemories of Migration: Cuban Exile and Poetics of Latinidad in Jennine Capó-Cruet’s Make Your Home Among Strangers
Authors: Aguilar-Ramírez Aarón 
Published: May 2021

Abstract
Taking Juan Flores’s premise of historical memory and lived experience to foundational to U.S. latinidad as a starting point, this article asks how twenty-first century second-generation Latina writing intervenes in contemporary understandings of U.S. latinidad as a pan-ethnic cultural field. It analyzes the narrative techniques, structures, and conventions through which contemporary Latinx writing engages ethnic memory and lived experience, considering how, and whether, those narrative conventions coalesce into a “poetics of latinidad.” Specifically, this article analyzes Jennine Capó Crucet’s Make Your Home Among Strangers (2015), a novel comprising two interlaced storylines that animate the categories “lived experience” and “historical memory.” The novel intertwines its protagonist, Lizet’s, lived experience as a second-generation Cuban-American and the fictionalized re-rendering of the Elián Gonzalez case, a historical event that has proved an inflection point for Cuban-American exile identity in the U.S., destabilizing Cubans’ status as an “exceptional” community in the U.S. Latinx migrant imaginary. Thus, this article argues that Capó-Crucet’s novel fashions a poetics of latinidad in key ways. Engaging Marianne Hirsch’s concept of “postmemory,” it analyzes how the interwoven stories of Lizet and Ariel Hernández (the fictionalized Elián González) repurpose the role of historical memory toward the narrative intelligibility of the second generation’s lived experience in the U.S. while recuperating and memorializing the first-generation’s experience of exile. It then situates this novel within a burgeoning corpus of twenty-first century Latina college narratives, including Patricia Cardoso’s Real Women Have Curves (2002), Meliza Bañalez’s Life is Wonderful, People are Terrific (2015), and Gabby Rivera’s Juliet Takes a Breath (2016). These texts rely on postmemory to address the experiences of second-generation Latina college students; Capó-Crucet’s novel articulates a poetics of latinidad in this intertextual framework.

Published: May 2021

Dynamic geometry software (DGS), especially GeoGebra, have been used in mathematics lessons around the world since it enables a dynamic learning environment. To date, there exist so many published researches about DGS, which leads to the need for meaningful organisation. This study aims to give a broad picture about researches related to DGS. For this reason, 210 articles accessed from the Web of Science database were analysed in terms of their purpose, research design, sample level, sample size, data collection tools and data analysing methods by using the content analysis method. According to the findings, for each section the most frequently used ones were as follows: ‘the effect of DGS on something’ as a purpose, qualitative method as a research design, high school students as a sample level, 101–300 intervals as a sample size, documents and achievement tests as instruments and descriptive analysis for quantitative and qualitative studies. These results can help researchers to see the past trends in DGS and conduct new studies.

Competency beliefs are beliefs about individuals’ ability to perform significantly regarding events that may affect their lives. People with higher levels of teaching competency beliefs do not escape from the experiences they have just encountered and have the determination to complete their actions successfully. Having general competencies of teachers and teacher candidates is of key importance in terms of creating more efficient and improving educational processes. Therefore, this study aimed to provide a systematic review on structure, criteria, and levels of professional teaching competence levels of preservice primary school teachers based on a comprehensive literature review. The study employs qualitative research methodology including document analysis and related content analysis. Various results were obtained from this study and the results were discussed with relevant literature and future implications are provided.

O desmonte da máquina-cinema: Pedro Costa e a estética do residual
Authors: Filho Osmar Gonçalves dos Reis , Aguiar David Leitão 
Published: May 2021

Ao termino de Ossos (filme de 1997), rodado nas Fontainhas, gueto lisboeta de cabo-verdianos, Pedro Costa percebe-se afetado por suas experiências no bairro e vê suas afetações não se concretizarem em suas imagens. Entre Costa e o fenômeno “Fontainhas” havia a máquina-cinema: um poder maquínico que desregula corpos e fenômenos e os recompõem num regime de imagens incapaz de dar forma visual às realidades residuais. Segundo pesquisadores que dialogam com a teoria das imagens – Jean-Louis Comolli, Gilles Deleuze, Giorgio Agamben, Vilém Flusser, entre outros – as tecnologias de poder, e aqui ressaltamos os dispositivos midiático-imagéticos, administram a produção simbólica de uma realidade determinada, e têm por estratégia produzir subjetividades subservientes (ou dessubjetivações) em proveito de um determinado projeto político. Apostamos que Costa, sobretudo em Juventude em marcha (filme de 2006), ao estabelecer um método político-estético para um subversivo regime de imagens, sua estética do residual, agenciará uma série de estratégias para efetuar um desmonte – ao menos uma remontagem – da máquina-cinema.
Makna Fonemik dalam Semantik Arab: Ontologi, Epistemologi, Aksiologi
Authors: Romanda Fharis 
Published: May 2021

This study aims to provide an understanding of the phonemic meaning (dalālah ṣawṭīyah) in Arabic semantics. To provide an understanding related to dalālah ṣawṭīyah, this study carries out its research based on a philosophical framework of thought consisting of ontology, epistemology, and axiology. It can be concluded that the discussion of this research broadly discusses the ontology or nature of ṣawṭīyah, its epistemology or method, and the axiology or function of the branch of the discussion of semantics. This research is based on a literature review. In analyzing data obtained from the literature review, this study used qualitative methods. This research has revealed the nature of sound, how sound works, and the function of each sound method in the Arabic interpretation process. This research concludes that the sound in the dalālah ṣawṭīyah has an important role in determining meaning in all language structures starting from Arabic words, phrases, and sentences. The method of sound work in giving meaning to Arabic can be in the form of differences in phoneme sounds, sound stress (al-nabr) in syllables or words, as well as intonation (al-tanghīm) that occurs in a phrase or sentence.

Published: May 2021

Sulfur-doped zinc oxide (S-ZnO) nanorod has been successfully synthesized via the seed-mediated hydrothermal method with different sulfur concentrations (0%, 1%, 2.5%). This research aims to study the influence of the concentration of sulfur on the structure, morphology, and optical properties of ZnO as a promising material in a wide range of applications. Crystal structure, morphology, and optical properties of the samples were characterized using X-Ray Diffraction (XRD), Field Emission Electron Scanning Microscopy (FESEM), and UV-Vis Spectroscopy, respectively. The XRD pattern shows the strongest peak at 2θ = 34.43° for crystal orientation of (002). The crystallinity properties of the S-ZnO sample are higher compared to the ZnO sample. The FESEM images of the 1% S-ZnO sample exhibit the highest nanorod density arrangement. The optical absorbance of the higher sulfur dopant possesses a higher optical absorption peak on the UV-Vis spectrum. The results indicate that S doping to ZnO can alter the structural, morphological, and optical properties of ZnO.
Legal Framework of Agricultural Land/Holding Succession and Acquisition in Slovenia
Authors: Avsec Franci 
Published: May 2021

Agricultural land legislation in Slovenia contains extensive special provisions that directly regulate the legal transfer of agricultural land and holdings inter vivos and mortis causa, including inheritance. Additionally, some measures within the common agricultural policy (such as financial support for the takeover of farms by young farmers) and tax policies (exemptions) provide incentives or alleviations for certain legal transactions involving the transfer of agricultural land and holdings. Among special provisions on the transfer of agricultural land and holdings, those relating to a statutory preemption right and a statutory priority right to lease agricultural land have the longest continuity (from the late 1950s). The holders of these priority rights must meet certain requirements and range in several priority classes. At first, agricultural organisations as legal persons had better priority rights than farmers. In 1990, the priority order was reversed by placing individual farmers before legal persons, individual agricultural entrepreneurs, and the National Agricultural Land and Forest Fund (NALFF). In 1973, the agricultural land legislation prohibited the division of certain middle-sized family farms (protected farms) through inheritance (mortis causa) and later (1986), also inter vivos, (with certain exceptions). The Agricultural Land Act and the Forests Act also restrict the division of certain agricultural or forest land plots. The draft acts of 2019 and 2020 prepared by the Ministry of Agriculture foresee important changes of the agricultural land policy, including the priority order between the statutory preemption rights and the removal of a general restriction on the division of protected farms inter vivos.

Empirical and Statistical Comparison of Intermediate Steps of AES-128 and RSA in Terms of Time Consumption
Authors: Pranav Prashant , Dutta Sandip , Chakraborty Soubhik 
Published: May 2021

Abstract
Cryptographic algorithms are composed of many complex mathematical functions. When analyzing the complexity of these algorithms, one fixes priory the overall complexity of the algorithm as the complexity of the most dominating operations for a group of operations. Generally, it is the count of this operation which determines the complexity of the algorithm in case of compounding operations. We have instead used the weight factor to determine the complexity of an algorithm with many operating functions working simultaneously and have taken time of the operation as a measure of the weight factor. We statistically analyze the two most used operations in RSA, namely "power" and "mod" through a method of revised difference to compare if these are statistically similar or dissimilar. We have also calculated the empirical computational complexity of these two operations through the fundamental theorem of finite differences to verify whether these operations are statistically dissimilar and if so then which of the two is dominant. We have also analyzed empirically the complexity of each of the four sub-steps involved in the encryption and decryption of AES-128, to determine which operation dominates the most and consumes most of the time in an overall run time of AES-128.
