Background: Among the current quality control assays used in islet transplantation, there is an urgent need
for more appropriate assays that measure cell damage via apoptosis that are accurate and rapid. Although
the Terminal Uridine Nucleotide End Labeling (TUNEL) is a popular marker for apoptosis, the protocol
takes 4 hours to complete. In this regard, microwave assisted histoprocessing, which shortens the time taken
for processing, holds promise. Keeping this in mind, a new TUNEL Microwave (TUNEL-MW) method, for
rapid quantification of apoptosis, was designed, developed and validated.
Method: Two lots of post-thaw isolated human islets cultured for 24 hours, 3 days, 5 days and 7 days i.e. 8
samples, were used for the study. Dewaxed and rehydrated tissues were processed for routine histology,
stained with haematoxylin and eosin (H&E) and the conventional TUNEL was carried out as per
manufacturer’s instructions. For the TUNEL-MW, kit instructions were modified and microwave-assisted
histoprocessing was done. The assessment of apoptotic index (AI%) by light microscopy (LM) was carried
out by a pathologist who was completely blinded to the study.
Results: The new TUNEL-Microwave (TUNEL-MW) developed by us reduced processing time from 4
hours to 30 minutes (saving 3½ hours). Results were validated by univariate linear regression (r2>0.990),
coefficient of variation (<5% between all three methods) and the Bland Altman plot comparing AI%
determined by the new TUNEL-MW with the conventional TUNEL and with LM (gold standard).
Conclusion: TUNEL Microwave appears to be an ideal method. It is simple and takes just 30 minutes to
perform and can therefore be used along with existing quality control measures to rule out or measure
apoptosis prior to islet release for islet transplantation.
Procurar a identidade através das imagens: I don't live here anymore

O artigo procura contextualizar o humano enquanto “ser dividido” – entre a totalidade e a falta; entre corpo e mente - e discutir a ideia de identidade contemporânea enquanto projeto. Utiliza a hipótese de Paul Ricoeur relativamente a uma possível “identidade narrativa”, feita da mesmeidade e da ipseidade, e associa a construção identitária à construção da aparência/ corpo. Para isso, analisa os percursos de construção dos sujeitos na contemporaneidade. Discute o trabalho do artista plástico Ugo Rondinone, na série I Don´t Live Here Anymore (série de fotografias em que o rosto do artista é adicionado a corpos de modelos, retirados das imagens que circulam nos media) enquanto possibilidade de metáfora acerca da procura de construção da identidade e aponta as possibilidades da imagem enquanto motor de busca permanente dessa construção identitária.

Published: August 2020

Fruit and small fruit crops are aﬀ ected by various viral diseases, leading to a decrease in yield and product quality, in connection with which the urgent task is to increase the reliability, sensitivity and productivity of diagnosing viruses and other dangerous pathogens. The solution to this problem is carried out by introducing new methods and technologies of molecular diagnostics, with the main attention being paid to decoding nucleotide sequences by sequencing. Sequencing provides a detailed description of the genome of the virus and allows one to get complete epigenomic information. Next generation sequencing (NGS) methods provide parallel testing for the presence of all malicious viruses in a single sample, including identiﬁ cation with a high degree of certainty of non-speciﬁ c and new viruses with the possibility of using diﬀ erent types of samples, for example, pollen. An example of NGS is the Illumina method, based on sequencing and bioinformatics analysis of short RNAs. Modern sequencers can generate from 4 million to 20 billion reads per cycle with read lengths from 50 to 300 nucleotides. The use of high-throughput sequencing (HTS) in conjunction with barcoding allows mass genotyping and characterization of viruses, analysis and elimination of PCR errors while maintaining the real diversity of gene libraries, as well as recognition of mutations in samples. New sequencing methods allow a deeper study of the genetic diversity of the strain composition of the viruses of fruit and small fruit crops. Some of the recently identiﬁ ed and infecting fruit crops belong to the genera of viruses previously unknown for these plant species (for example, Fabavirus, Luteovirus). Complete RNA sequencing was used to identify and characterize the viruses of grape, apple, pear, and cherry. In cultivated Prunus species, 44 viruses have been identiﬁ ed. A new ilarvirus was discovered on the apple tree – the Apple necrotic mosaic virus. The use of HTS for the analysis of fruit and small fruit viruses is becoming increasingly widespread. With a decrease in the cost of sequencing, the introduction and validation of new molecular methods will make it possible in the near future to use them in the diagnosis of viruses by State surveillance authorities.

The Adsorption Efficiency of Atap Fruit Shell (Arenga pinnata Merr) on remove Chromium Metal Ions from aSolution        Arenga pinnata fruit shell was dried, pulverized, and used for biosorption of Cr(III) and Cr(VI) from a solution. Column experiments were conducted to investigate the affected parameters of pH solution, particle size, chromium metal ion concentration, flow rate and amount of mass biosorbent. The maximum adsorption efficiency of metal ions Cr(III) and Cr(VI), was 47.79% and 41.47% respectively, initial metal ion concentrations of 75-100 mg/L at initial pH of 3 for Cr(VI) and initial pH of 4 for Cr(III) with the particlesize ≤180μm and flow rate of 1-2 mL/min. Adsorption capacity will increase with increasing the number of mass biosorbent, however adsorption efficiency will decrease. An FTIR examination revealed changes between the natural and heavy metals-loaded biomaterial. Scanning electron micrograph (SEM) also revealed changes in the surface morphology of thebiomass as a result of heavy metal adsorption.

Lexical and Contextual Variability of Idiomatic Phrasal Verbs in Harry Potter and the Deathly Hallows Movies
Authors: Ghofar Romli Hairus Salikin,
Published: August 2020

The popularity of Harry Potter and the Deathly Hallows (HPDH) as a novel is almost accentuated in the movie version. However, the fascination of watching the movies may be interrupted by the problems arising from the use of some problematic expressions in the original language, especially idiomatic phrasal verbs (IPVs). This paper undergoes some procedures of the analysis starting from the process of data collection, progressing to selection, filtering, and labeling. It extracts PVs in HPDH (97 in HPDH part one and 70 in part two)using linguistic concepts of PV. Later by limiting the PVs under conventional and characteristics modelling function of idioms, IPVs can be identified and served as the primary data. The final phase of the analysis wants to see how lexical interpretation, relying on Oxford Advanced Learner’s Dictionary 8th Edition (OALD 8thed), and Halidayan contextual variability (field, tenor and mode) help classifying and explaining the meanings of the IPVs. Finally it is expected that this paper can offer appropriate logical and contextual interpretations of the IPVs. This way, by watching the HPDH, learners of English can gain better understanding of the movies and, more importantly, better knowledge of IPVs as inseparable part of their competence of EFL.Keywords: HPDH, IPVs, lexical interpretation, contextual variability, contextual interpretations
