Authors: Şeker Muzaffer , Yalçın Haydar
Published: July 2021

Müsilaj (deniz salyası) hemen hemen tüm bitkilerin ve bazı mikroorganizmaların ürettiği kalın, yapışkan bir maddedir (Mecozzi vd., 2005). Biyolojik ve kimyasal birçok koşulun bir araya gelmesiyle oluşmaktadır. Bitkilerde su ve gıdanın depolanması, tohumların çimlenmesi ve zar kalınlaşması benzeri işlemlerde çeşitli roller üstlenir (Danovaro vd., 2009). Son dönemde Marmara Denizi’nde yaşanan durumla ülkemizin gündemine oturan deniz salyasının oluşumunda çok farklı sebepler gündeme gelse de üç temel etmenden bahsetmek mümkündür: Deniz sıcaklıklarının ortalama sıcaklıkların üzerine çıkması, denizlerdeki kirlilik oranının artması ve denizin durağan olması (Keleş vd., 2020). Bahsi geçen bu üç durumun gerçekleşmesi durumunda bazı plankton türlerinin hızla çoğalmaya başlamasıyla deniz salyasının artış gösterdiği bilinmektedir. Bu çalışmada deniz salyası üzerine yapılan bilimsel araştırmaların genel özellikleri üzerine odaklanılmıştır. Çalışmada deniz salyasına yönelik araştırmaların disiplinler arası yapısı veriye dayalı bir analizle gözler önüne serilmiştir. İş birliği örüntüsünün yüksek olduğu bu çalışmalarda Zoology, Plant Sciences, Oceanography, Marine & Freshwater Biology, Limnology, Fisheries, Environmental Sciences ve Ecology disiplinlerinin ortaklaşa çalışmalar yürüttüğü gözlemlenirken, İtalya, Fransa, Çin, Hırvatistan ve ABD yayın sayısı bakımından dikkat çeken ülkeler arasında yer almıştır. Coğrafi alan olarak kuzey Adriyatik denizi üzerine yapılan çalışmaların sıklığı dikkat çekerken, Univ Bologna, Univ Gottingen, Univ Melbourne, Univ Genoa ve İstanbul Üniversitesi kurumsal olarak yayın sayıları dikkat çeken üniversiteler arasında yer almıştır.

Personality Factors Determine the Attitudes toward Eating Behavior
Authors: Adachi Miki Adachi , Adach Keisuke
Published: July 2021

The purpose of this study was to clarify the personality factors that determine the difference in perception of how the order of eating and the mechanisms by which these factors operate, focusing on the attitudes toward eating behavior of eating what you like first or leaving them behind. We tested the following hypotheses about comparisons of people who eat what they like first and people who eat what they like later: (1) Perfectionism scores of those who eat later will be higher than the corresponding scores of those who eat first, (2) Optimism scores of those who eat first will be higher than the corresponding scores of those who eat later. We found that the difference in attitude toward eating behavior between first and later are related to the difference in optimism and perfectionist tendencies against the background of habituation and automation of eating behavior patterns. Although attitudes toward eating behavior are experienced by all people, they have been habituated and automated by individuals independently.

Economic Value of Ecosystem Disservices of Green Spaces found in Residential Plots of Dar es Salaam City
Authors: Mwageni Nicholaus , Kassenga Gabriel
Published: July 2021

Most studies have reported benefits of green spaces to households but few studies have been reported on negative effects (disservices) as well as their economic cost. Understanding ecosystem disservices from home greenery is important for health, safety and security of urban environment. The current paper reports on a study on economic value of green spaces including aesthetics, health, safety and security, physical, social and economic disservices. The study employed focus group discussion and in-depth interviews using structured questionnaire. Results indicate that, 65% of the respondents face the aforementioned disservices. Disservices which are aesthetic in nature were found to be faced by majority followed by health and physical disservices. The study has shown that households spend an average of TZS 60,691 (USD 26) per year on prevention and control of aesthetic and health disservices. In totality, valuation of ecosystem disservices from home greeneries has revealed that a household can incur an average total cost of TZS 116,817 (USD 50) per year. At City level, the total disservice cost is estimated to be TZS 106 billion (USD 45,415,595) per year. Disservices affect 5% of the annual household income on preventing and controlling their impacts. The study recommends that departments responsible for handling environmental management issues should recognize the value of green space and integrate aesthetic factors into their planning and budgeting.
Post-transfusion purpura due to anti HPA–1a antibodies –
a retrospective case report
Authors: Andrys Bożena , Polcyn-Adamczak Magdalena
Published: July 2021

Post-transfusion purpura is a life-threatening adverse reaction associated with a reduction in platelet counts below 10
x 109/L and bleeding. It usually occurs in women who, due to their pregnancies, have developed antibodies directed
against human platelet antigen (HPA), most often anti-HPA 1a. The case described by us concerned an 83-year-old woman
who received two units of red blood cells (RBC) due to severe secondary anemia. Seven days after the transfusion, she
developed skin symptoms of thrombocytopenic diathesis, gastrointestinal bleeding, and a reduced number of platelets
(3 x 109/L), and the patient’s serum (genotype HPA-1b/1b) was positive for anti-platelet antibodies with HPA-1a specificity
and directed against human leukocyte antigen (HLA) class I and class II antibodies, unresponsive to the lymphocytotoxic
test. Prompt diagnosis by our transfusion medicine consultant and the initiation of treatment with intravenous immunoglobulins
certainly shortened the duration of thrombocytopenia and bleeding, and possibly also saved the patient’s life.
Collision Cutaneous Neoplasms Consisting of Melanoma and Basal Cell Carcinoma
Authors: Aghighi Maryam , Chercover David , Rahvar Maral
Published: July 2021

Collision tumors are defined as two histologically different tumor types that arise at the same anatomical location. According to the literature review performed, there are reports of 27 cases of collision tumors involving lentigo maligna melanoma (LMM) in-situ and basal cell carcinoma (BCC). In the absence of melanocytic extension beyond the lamina propria of the BCC compartment, mixed tumors are considered as melanoma in-situ colonizing the BCC, rather than invasive melanomas. We report an uncommon case of collision of BCC with LMM, two primary skin tumors that are seen in patients with significant sunlight exposure. In our case, the patient is a 91-year-old male presented with a translucent plaque with areas of brown pigmentation on his left lateral canthus. He had a history of multiple BCCs, squamous cell carcinomas and an invasive melanoma of right cheek. Given the clinical impression of BCC, the lesion was curetted. Histological examination demonstrated melanoma in-situ heavily infiltrating the dermal nodules of BCC. Deposits of melanin pigment were scattered throughout the tumor. The BCC contained about 50% atypical melanocytes. Further immunohistochemical evaluation with melanocytic and epithelial markers (melanin A, SOX-10, pan-cytokeratin and p63) confirmed the diagnosis. An unequivocal independent invasive melanoma component was not identified in this material. The collision of BCC and LMM is very rare.  However, given the sun-damaged changes promote both tumors, their development at the same site, although unexpected, can be explained. Since the prognosis of the two entities is independent, wider excision to exclude invasive malignant melanoma is indicated.
Prevalence of Metabolic Syndrome and Its Parameters and Their Correlations With Psoriasis Duration, Severity, and Sleep Quality In Psoriasis Patients: A Cross-Sectional Study
Authors: Tas Betul , Kabeloglu Vasfiye
Published: July 2021

Background: Psoriasis is an inflammatory skin disease that may lead to comorbidities, including metabolic syndrome (MS).

Objective: We determined the prevalence of MS and its correlation with psoriasis duration, severity, and sleep quality in psoriasis patients.

Methods: A total of 112 subjects with chronic plaque psoriasis were studied. Demographics, MS parameters, disease duration, severity, and sleep quality were examined. The Psoriasis Area and Severity Index (PASI)and the Pittsburgh Sleep Quality Index (PSQI) were used to assess psoriasis severity and sleep quality, respectively. Presence of MS and its correlations with psoriasis duration, severity and sleep quality were investigated.

Results: Of 112 patients, 76 (67.8%) were diagnosed with MS. Of all patients, 74.1% had a high PASI, and 84.8% had a high PSQI. The mean values of psoriasis duration, body mass index, waist circumference, fasting glucose, HOMA-IR, triglyceride levels, blood pressure, PSQI, sleep latency, and daytime sleep dysfunction were significantly higher in the MS group than non-MS group, whereas the mean HDL level was lower. The prevalences of MS, high fasting glucose, and low HDL were significantly higher among female, but not male, patients with severe psoriasis (PASI >10) than those without severe psoriasis. Disease duration, high body mass index, waist circumference, blood pressure, fasting glucose, HOMA-IR, triglyceride levels, low HDL, and poor sleep quality were significantly correlated with the presence of MS. However, only waist circumference, fasting glucose, blood pressure, and low HDL were predictive of the development of MS.

Conclusions: MS is common among psoriasis patients, and especially in females with advanced psoriasis, high fasting glucose, and low HDL levels. Besides diagnostic criteria of MS, a long duration of psoriasis, poor sleep quality and high-HOMA-IR correlate with the development of MS. High fasting glucose and low HDL levels may facilitate MS development in association with psoriasis severity in females.
Efficacy and Safety of 25% Trichloroacetic Acid Peel Versus 30% Salicylic Acid Peel in Mild-to-Moderate Acne Vulgaris: A Comparative Study
Authors: Dayal Surabhi , Singh Satbir , Sahu Priyadarshini
Published: July 2021

Background: Both salicylic acid (SA) and trichloroacetic acid (TCA) have proven efficacy with goodsafety profiles in the treatment of acne vulgaris.

Objectives: This study compared the clinical efficacy and safety of 25% TCA and 30% SA peels in thetreatment of mild and moderate acne vulgaris.

Methods: Patients with mild or moderate acne vulgaris were randomized into 2 groups of 25 personseach, and treated with either the TCA peel or the SA peel at 2-week intervals for 12 weeks. Evaluationof active acne was done by individual lesion counts (comedones, papules and pustules) and calculationof the Michaelsson acne score (MAS).

Results: Both peels led to significant decrease in individual lesion counts and MAS compared to baselinevalues, without significant differences between the treatment groups. Thus, the peels had equivalentefficacy against acne vulgaris. The TCA peel was better in treating non-inflammatory lesions,while the SA peel was better for inflammatory lesions, but the differences were not significant. Noserious adverse effects were recorded, but more patients in the TCA peel group experienced burningand stinging sensations.

Conclusion: The efficacy of 25% TCA is comparable to that of 30% SA in mild-to-moderate acnevulgaris, but safety and tolerability were better with the SA peel than TCA peel.
Acquired White Oral Lesions with Specific Patterns: Oral Lichen Planus and Lupus Erythematosus
Authors: Manfredini Marco , Pedroni Gioia , Bigi Laura , Apponi Roberto , Murri dello Iago Alberto , Dattola Annunziata , Farnetani Francesca , Pellacani Giovanni
Published: July 2021

Background: Diagnosis of oral white lesions might be challenging. These lesions represent a wide spectrum of diseases with different etiology and prognosis. Oral white lesions can be categorized into two major groups, congenital and acquired, according to their development, and in four subgroups: lesions which can be scraped off or not and lesions with special pattern or not.

Objectives: The aim of this manuscript is to review, from diagnosis to treatment, the current knowledge on oral white lesions with specific pattern.

Methods: A review on oral white lesions with specific pattern was conducted on PubMed and Scopus from inception to January 2021.

Results: Among acquired lesions with specific pattern two clinical entities are mostly represented: Oral lichenoid reactions and Lupus erythematosus. The etiology of both diseases is still not known but their pathogenesis is mainly immunological. At present the mucoscopic features of those disease have been described only in few case reports or case series. Immunomodulatory therapies are often the agents of choice for their treatment.

Conclusions: The collaboration of dermatologists and dentists as a team is important for early diagnoses and effective treatments. Mucoscopy is a promising technique which may reveal important features for the differentiation of OLP and LE oral white lesions.
Technical Staffing Ratios
Authors: Novis David A. , Coulter Suzanne N. , Blond Barbara , Perrotta Peter
Published: July 2021

Context.—

Laboratory managers and medical directors are charged with staffing their clinical laboratories as efficiently as possible.

Objective.—

To report and analyze the results of 3 College of American Pathologists Q-Probes studies that surveyed the normative rates of laboratory technical staffing ratios.

Design.—

Participants in the College of American Pathologists Q-Probes program submitted data on the levels of staffing and test volumes performed in their laboratories in 2014, 2016, and 2019. From these data, we calculated departmental productivity ratios, defined as testing volume per full-time equivalent, and degrees of managerial oversight, defined as the ratio of nonmanagement to management full-time equivalents. Participants completed general questionnaires surveying their hospital and laboratory demographics and practices, the data from which we determined demographic and practice characteristics that were significantly associated with technical staffing ratios.

Results.—

Sixty-seven, 82, and 79 institutions submitted data for the years 2019, 2016, and 2014, respectively. Technical staffing ratios varied widely among the various laboratory departments within each institution and among different institutions participating in this study. With the exception of cytology departments, productivity and managerial oversight ratios did not significantly change between these 3 studies. In the 2019 study, greater testing volumes were associated with higher productivity ratios. Significant associations between managerial oversight ratios and practice characteristics were not consistent across the 3 studies.

Conclusions.—

Technical staffing ratios varied widely among the various laboratory departments within each institution and among different institutions participating in this study.

Mujeres en resistencia: estrategias subversivas en la cárcel de Santa Martha Acatitla, Ciudad de México
Authors: Ballester Martínez Virginia
Published: July 2021

Las violencias y los mecanismos disciplinarios que se instauran en la prisión dificultan, pero no anulan, la posibilidad de que las mujeres desarrollen estrategias de resistencia dentro de los espacios carcelarios. En esta investigación se realiza, desde una perspectiva feminista, un análisis cualitativo a través del intercambio narrativo con 13 mujeres privadas de su libertad en la cárcel de Santa Martha Acatitla (Ciudad de México), con el objetivo de examinar aquellas acciones subversivas dentro de prisión, así como de identificar los obstáculos institucionales para el desarrollo de estas. Tras el análisis discursivo de las entrevistas y de los grupos de discusión, los resultados visibilizan la importancia de lo corpóreo y de la cotidianeidad en el surgimiento de los espacios de resistencia entre las mujeres dentro del contexto de privación de libertad.
La (de)construcción del género en la ficción política: el caso de Borgen
Authors: Borràs Isnardo Marina
Published: July 2021

La presente investigación se centra en la representación de las mujeres políticas en las ficciones seriadas a través de la serie Borgen (2010-2013) y desde una perspectiva de género. Para ello, desde una metodología cualitativa, se realiza una revisión de los estereotipos de género que marcan habitualmente a los personajes de mujeres políticas en la ficción y se comprueba si se reproducen o se rompen en la serie objeto del estudio. Los resultados de la investigación revelan que Borgen presenta una transgresión del género en lo relativo a cuatro ámbitos: conciliación vida pública-privada, rasgos de personalidad, competencia temática y liderazgo, proponiendo así una hoja de ruta para la representación de las mujeres en los medios de comunicación, así como para la realización de una comunicación política desde una perspectiva de género.

Grønlændernes holdninger til udenrigs- og sikkerhedspolitiske spørgsmål: indsigter fra en survey
Authors: Leander Nielsen Rasmus , Ackrén Maria
Published: July 2021

Hvad mener grønlænderne om de ændrede geopolitiske dynamikker i Arktis, udenrigs- og sikkerhedsmæssige udfordringer samt om forskellige internationale samarbejdspartnere? Disse og lignende spørgsmål bliver ofte stillet, men for første gang har vi data til at analysere et repræsentativt udsnit af den grønlandske befolknings holdninger til den omverden, der i de senere år i højere og højere grad har rettet blikket mod Arktis og Grønland. Artiklen præsenterer og diskuterer de væsentligste fund fra en survey-undersøgelse foretaget ultimo 2020 med fokus på aktuelt trusselsbillede, grønlændernes syn på stormagterne og især internationale samarbejdspartnere og organisationer.
Grønlands udenrigspolitik før og nu: Fra købmændenes budskab til bilaterale aftaler
Authors: Høegh Kenneth
Published: July 2021

Denne artikel belyser de vigtigste historiske begivenheder i udviklingen af Grønlands udenrigspolitik og præsenterer de væsentligste emner og relationer i Grønlands nutidige engagement på verdensscenen. Første del fokuserer på udviklingen fra dansk koloni til indførelsen af selvstyre, hvor især besættelsen af Danmark under 2. Verdenskrig var afgørende for, at Grønland ikke længere var isoleret fra omverdenen, mens den efterfølgende politiske udvikling banede vejen for større udenrigspolitisk selvbestemmelse. Anden del handler om Grønlands udenrigspolitiske udsyn i dag, hvor den store internationale interesse i Arktis stiller udenrigsdepartementet i en ny situation, hvor man søger større indflydelse på det udenrigs- og sikkerhedspolitiske område. I den henseende er det styrkede samarbejde med USA et centralt element, mens en bedre repræsentation i det regionale samarbejde i bl.a. Arktisk Råd er en væsentlig prioritet, da Grønland er selve årsagen til Kongerigets involvering i arktisk politik. Den overordnede prioritet såvel nu som før er og bliver en omverden i fred og fordragelighed, da et samarbejdende og sikkert Arktis altid vil være fordrende for fortsat udvikling af Grønland.
La condición transreal: información expandida y hacktivismo en el Media Art
Authors: Fernández Castrillo Carolina
Published: July 2021

Desde el Media Art hallamos una larga serie de expresiones culturales de carácter innovador en respuesta a las nuevas inquietudes e intereses surgidos en la era de la posverdad. En la presente investigación se hará especial hincapié en el importante papel del hacktivismo para incentivar la participación ciudadana en la lucha contra la desinformación y el abuso de poder desde el ámbito más experimental de la cultura digital. Adoptaremos como objeto de estudio el corpus artístico de Paolo Cirio, por su interés al abordar el papel central de la información como medio y contenido creativo. En sus obras, la activación de originales mecanismos de visualización de datos e interacción con el usuario va dirigida no solo a denunciar injusticias y falsedades, sino también a estimular una intervención real sobre los propios hechos. A partir del análisis de algunas de sus principales aportaciones se establecerá un marco teórico original para la identificación de aquellas aportaciones creativas que entran dentro de la que denominaremos “condición transreal”. La relevancia de esta propuesta reside en el planteamiento de unas coordenadas para el estudio de aquellos proyectos transmedia de carácter interactivo, y en la mayoría de las ocasiones contestatario, capaces de brindar un nuevo modelo de relación con la audiencia y una atractiva estrategia de expansión del universo informativo desde el compromiso social mediante una acción directa sobre la realidad.
La anamorfosis en el arte contemporáneo. Un análisis de las diferentes estrategias de su aplicación en las creaciones de artistas actuales
Authors: Soriano-Colchero Jose-Antonio
Published: July 2021

La anamorfosis es una variante de la perspectiva matemática estudiada por artistas e in-telectuales europeos desde el siglo xvi, y se alcanzó la publicación del método definitivo en el siglo xvii. Su original aura misteriosa sería sustituida, debido a la consideración sobre las imágenes a las que se le aplicaba, por mero entretenimiento tras su popularización durante el siglo xviii, mediante los gabinetes de curiosidades y Kunst-und Wunderkammeern. No obstante, la anamorfosis ha continuado estudiándose y aplicándose a proyectos de creación artística. Así, el objetivo de la presente publicación es el desarrollo de una actualización sobre cómo la anamorfosis es aplicada al arte contemporáneo a través del estudio de numerosas obras, evidenciando las posibilidades técnicas y conceptuales que este sistema ofrece tanto al arte en sí como a la sociedad en general a través de este. Todas las obras analizadas –relacionadas con la anamorfosis óptica y catóptrica a través de la escultura, la fotografía y la pintura de artistas callejeros o relacionados a las galerías de arte– propician un discurso que invita a la reflexión sobre la realidad contemporánea o hiperrealidad. Con ello, damos a conocer el método de la anamorfosis, además de incentivar a los artistas visuales a aplicarlo en futuras creaciones, dado el interés que genera el método por su versatilidad en cuanto a potencial metodológico y de significación, demostrado en el cuerpo del artículo y en las conclusiones. La imagen anamórfica es entendida, por lo tanto, como metaimagen que evidencia su propia artificiosidad, incitando al observador a reflexionar sobre la realidad y exigiendo nuevas formas de interpretar lo observado.
Discurso videolúdico y transhumanismo en SOMA
Authors: Pina Arrabal Álvaro
Published: July 2021

En este trabajo se realiza un análisis del discurso videolúdico de SOMA (2015), seleccionado por su alta carga diegética, filosófica y, en última instancia, discursiva. Las ideas sobre la ética del transhumanismo y la conciencia humana que plantea se estudian como parte de un discurso mayor: los límites morales de la ciencia y la tecnología. Así, se ofrece un marco teórico en el que se señala la potencialidad discursiva de los videojuegos a partir de su carga narrativa. En concreto, se aboga por una concepción del videojuego como discurso multimodal electrónico, de manera que para analizar un discurso videolúdico haya que atender a los distintos elementos multisemióticos que lo integran y no solo al texto (lo que supondría sesgar y/o limitar el análisis del discurso en cuestión). Se parte de presupuestos narratológicos y se proponen siete indicadores discursivos que encauzan el discurso multimodal de SOMA: cronotopos diegéticos, elementos metamórficos narrativos, elementos narrativos opcionales, actantes con potencial cesativo, diálogos, decisiones morales y el cuestionario. Se concluye que los videojuegos, en cuanto que “sistemas afectivos” (Anable, 2018), propician la representación y consiguiente transmisión de sentimientos humanos complejos (como los derivados de la propuesta transhumanista) que cabe estudiar desde un análisis del discurso multimodal que atienda a los distintos componentes semióticos que integran el videojuego.
La transformación de la ciencia ficción: un análisis cuantitativo del patrón emocional en los premios Hugo
Authors: Arroyo Barrigüete José Luis
Published: July 2021

La ciencia ficción como género literario ha estado en constante evolución desde sus orígenes, a principios del siglo pasado. Sin embargo, en las últimas décadas esta evolución se ha acelerado, pasando de ser un género de corte conservador a adoptar enfoques más próximos al progresismo político (Oleszczuk, 2017). El objetivo de esta investigación es determinar si esta transformación se aprecia también en la construcción estilística de las obras y, más concretamente, en su patrón emocional, desarrollando un estudio sincrónico dual de las décadas de 1960 y 2010. Concretamente se han analizado veinticuatro obras galardonadas con el premio Hugo, probablemente el más relevante en el ámbito de la ciencia ficción y, en menor medida, de la fantasía, doce de la década de 1960 y otras doce de la década de 2010. Sobre este corpus de documentos se han aplicado tres técnicas de lingüística computacional: análisis de sentimientos, clústering y componentes principales, a fin de identificar grupos homogéneos de novelas. Los resultados muestran la agrupación en tres clústeres claramente diferenciados, con patrones emocionales disímiles, y que correlacionan fuertemente con la década en que fueron escritas. Esto confirma que, adicionalmente a la evolución temática, se ha producido un cambio sustancial desde el punto de vista estilístico.
Diffusion: Emotional Visualization Based on Biofeedback Control by EEG
Authors: Xu Shuai , Wang Zhe
Published: July 2021

Diffusion is an area of research exploring the interactive relationship between human consciousness and computational practice by analyzing human brain data from electroencephalogram (EEG)-based brain-computer interfaces and interactive devices that can generate music and synchronized visual images by biofeedback. Although interactive experience is not a new topic in computational art, it has provoked thought due to the significant influence of technology on human ideology, emotions, morality, ethics, etc. Diffusion is the result of attempts to establish a connection between human physiological information and digital technology. As well as experimental research, it based on the ethical level of artificial intelligence (AI). Diffusion uses music visualization to transform intangible brain activity (thoughts or emotions) into perceivable things (sounds or objects). The research emphasizes human consciousness in AI and points out the blurred boundaries between AI and human creativity. Therefore, the installation evaluates human motivation, which can present as abstract structures—like creativity, emotion, and insight—which enhance the interactive experience of participants and deconstructs the inherent meaning of the material and spiritual, reality and virtual reality or humans and machines. By reviewing and contextualizing EEG and digital music development research, we finally outline a future research area that will involve deep collaboration across interdisciplinary and multiple technologies to realize emotion recognition.
NFT and digital art: new possibilities for the consumption, dissemination and preservation of contemporary works of art

Digital technology, which appeared in the '80s and consolidated itself in the following decade with what was called the “third industrial revolution”, has transformed not only our daily environment, but also the way in which we produce and experience the artistic work. Digital art, a subcategory of the so-named art of the new media, presents multiple forms and is in continual evolution, parallel to the devices which make it possible; but its commercialisation in the contemporary art market becomes complex, so digital works present a series of characteristics such as the paperless ofice, obsolescence and reproducibility which may be considered to be not particularly profitable by collectors.

Despite this, in recent months the sale of some digital artworks, to which numerous texts are referred to under the name of cryptoart, have increased notably, reaching figures in the millions for the first time in auction houses. The commercial success of these pieces is due to the fact that, together with the work's archive, they include a type of cryptographic certificate, the non- fungible-tokens or NFTs, which collect the the work's data and inscribe them in a blockchain; transforming a multiple and disseminated work into a digital item that is unique and traceable, whose property can be transmitted as one would do with any other object in the offline world. Although they favour in principle the creation and sale of digital art, NFTs present their own problems, especially related to their access, use and sustainability; are NFTs a permanent tool or only a method of fleeting speculation? How does this certification affect property and the author's rights? Is it possible and will it be sustainable to employ them as a strategy for the preservation of digital works?

This article carries out an analysis of the principal characteristics and problems of digital art in a general sense, as well as the solutions and preoccupations which the cryptographic certificates offer in all aspects in the life of a work of art: production, dissemination and preservation.

Vitamin C in the Prevention of Contrast-induced Nephropathy among High-risk Patients Undergoing Coronary Angiogram: A Meta-analysis
Authors: Ong Rainnier Y. , Palanca Lou Andrew , Agustin Leana
Published: July 2021

Background: Contrast-Induced nephropathy (CIN) is one of the leading causes of acute kidney injury. The most common procedures associated with CIN are coronary angiography and contrast enhanced computed tomography (CT) [1].  The most common definition in use is an increase in serum creatinine (SCr) of >25% of the baseline values occurring following the intravascular administration of contrast media without an alternative explanation [2]. Generation of reactive oxygen species is thought to play a role in the pathogenesis of CIN, hence researches have been conducted into the potential role of antioxidants in the prevention of contrast-induced nephropathy [3]. Vitamin C, a potent antioxidant in humans has the ability to oxidize free radicals, and has been studied in different trials to measure its ability to prevent CIN among patients undergoing coronary angiogram.

Objective: To determine if vitamin C prevents CIN among High-risk patients (Creatinine Clearance <60 ml/min/m2, Diabetics, and on administration of high-volume contrast media).

Methodology: All studies, limited to randomized clinical trials were sought for this analysis through PubMed, the Cochrane Library, ClinicalTrials.gov. Database was searched using the terms “vitamin C”, “Prevention”, “acute kidney injury” and “contrast-induced nephropathy”. Adult patients (40-90 years old) with Creatinine Clearance of <60 ml/min/m2 or baseline creatinine >1.2 mg/dl, Diabetes Mellitus Type II, and were administered with high-volume contrast media (>100ml) undergoing coronary angiogram were included in the study. Exclusion Criteria were patients with normal baseline renal function, without risk factors for CIN, with EGFR < 30 ml/min/m2, with regular intake of Vitamin C and were on dialysis. Statistical data were obtained using Review Manager (RevMan) Version 5.3 freeware program.  P Value was obtained using the Cochran–Mantel–Haenszel test (CMH).  Included patients were given Vitamin C at doses of 1 gram to 3 grams, taken orally or administered intravenously pre-and post coronary angiogram.

Results:  Seven hundred and one (N=701) patients were included in this meta-analysis.  CIN occurred in 3.5% of patients (N=25) in the ascorbic acid group and in 6% of patients (N= 42) in the placebo group (p value of 0.03).

Conclusion: Vitamin C given at doses 1 gram to 3 grams in combination with hydration prior to coronary angiogram may have a significant effect in the prevention of CIN in high-risk patients.
Review on SARS- CoV-2 Transmission, Infection and Pathogenesis in Animals
Authors: Okechukwu Nwiyi Paul
Published: July 2021

Coronavirus are single stranded, positive sense, enveloped virus that belongs to the order Nidovirales. Coronavirus consists of pathogens of many animal species and humans including the current severe acute respiratory syndrome coronaviruses (SARS-CoV). This review considers the transmission, pathogenesis and diagnosis of coronavirus in animal.  Transmission of coronavirus is by inhalation of aerosol or droplets containing the virus via respiratory system and close contact with infected patients. Clinical signs exhibited by coronavirus infected animals are; coughing, sneezing, diarrhea, fever and gastrointestinal symptoms. Coronavirus pathogenesis involves viral attachment or entry, replication, transcription, translation, assembly and eventual release. Polymerase chain reaction is the most modern and acceptable method for coronavirus detection because of its sensitivity and accuracy, though, several other methods abound. The PCR amplifies a specific region of a DNA strand; employs thermal cycling and the main agents are primers and a DNA polymerase.  The process of denaturation, annealing and elongation constitutes a single cycle. Multiple cycles are required to amplifiy the target DNA to millions of copies.
The tyrosyl‐tRNA synthetase from Escherichia coli
Authors: Barker D.G. , Bruton C.J. , Winter G.
Published: July 2002

The structural component of the tyrS gene of Escherichia coli, comprising 1269 base pairs, has been fully sequenced by the combined M13/dideoxychain termination approach. The gene has a codon usage pattern which is typical of highly expressed proteins and similar to other Escherichia coli aminoacyl‐tRNA synthetase genes. Peptide purification and sequencing has been used to locate the N‐terminus and to provide confirmation of 95% of the translated protein sequence. This latter yields on M
r of 47 403 for the Escherichia coli tyrosyl‐tRNA synthetase, and reveals considerable homology with the primary structure of the analogous enzyme isolated from Bacillus staerothermophilus.
The activation segment of procarboxypeptidase A from porcine pancreas constitutes a folded structural domain
Authors: Avilés F.X. , San Segundo B. , Vilanova M. , Cuchillo C.M. , Turner C.
Published: July 2002

The controlled action of trypsin on porcine pancreatic procarboxypeptidase A releases a large activation peptide which contains the activation segment of the proenzyme. Circular dichroism studies indicate that the isolated activation peptide contains a high percentage of residues in ordered secondary structures (mainly α‐helix). This result agrees with predictions of secondary structure carried out on the published amino acid sequence of the homologous rat proenzyme. Moreover, proton magnetic resonance spectroscopy shows that the peptide adopts a thermostable tertiary structure with characteristics typical of globular proteins. The results as a whole indicate that the activation segment of porcine pancreatic procarboxypeptidase A constitutes a folded structural domain.
Phosphorylation of smooth muscle myosin light chain by five different kinases
Authors: Singh Toolsee J. , Akatsuka Akira , Huang Kuo-Ping
Published: July 2002

Phosphorylation of the 20 kDa myosin light chain from smooth muscle by five different kinases was investigated. Three of the kinases (myosin light chain kinase, phosphorylase kinase, and cAMP‐dependent protein kinase) phosphorylate serine residues, the fourth (casein‐kinase‐2) mainly threonine, and the fifth (glycogen synthase (casein) kinase‐1) both serine and threonine. Isoelectric focusing analyses of 32P‐labelled chymotryptic peptides indicate that phosphorylase kinase and cAMP‐dependent protein kinase phosphorylate the same site as myosin light chain kinase. However, both casein kinase‐2 and glycogen synthase (casein) kinase‐1 phosphorylate different sites.
