Abstract. Ziane L, Djellouli M, Berghioua A. 2021. Short Communication: Chemical composition, antioxidant and antimicrobial activity of Fagonia longispina (Zygophyllaceae) of Algerian. Biodiversitas 22: 3448-3453. The study's aim is to discover the antioxidant, antibacterial efficacy and identifying the main constituents of the essential oil of Fagonia longispina from southwest of Algeria. The essential oil from the aerial parts of the endemic plant Fagonia longispina collected from the region of Sahara southwest of Algeria was isolated by hydrodistillation and analyzed by gas chromatography-mass spectrometry. Our work was designed then, to evaluate the antioxidant activity of the essential oil of Fagonia longispina by DPPH free radical scavenging and HPTLC techniques. Antibacterial potency of essential oil from this plant has been tested against Staphylococcus aureus (ATCC 29213), Escherichia coli (ATCC 25922), and Bacillus cereus (ATCC11778) by disk diffusion assay. We found that the chemical profile of the essential oil revealed the presence of 14 compounds: Trans–Pinocarveol (3.14 %), Panisaldehyd (4.24 %), Trans geraniol (3.05 %), carvacrol 18.72 %), Elemicin (22.85 %), (Z,E) Farnesol (15.69 %), Caryophyllene oxide (2.68 %), Alpha-curcumene (1.75 %), Germacrene D (4.22 %), longipinane (2.89 %) and ?-Terpinine (2.74 %). The antioxidant assay showed that the essential oil could scavenge DPPH (IC50 values of 2.1959 mg/mL free radical. The essential oil exhibits very effective antimicrobial activity using disk diffusion assay method with minimum inhibitory concentration ranging from 0.75 ?L/mL to 1.9714 ?L/mL. These results showed that this native plant may be a good candidate for further biological and pharmacological investigations.

We present an automated method for measuring the lineal density of red blood cells (RBCs) in human retinal capillaries using adaptive optics near-confocal ophthalmoscopy (AONCO). The spatiotemporal traces of RBCs flowing in retinal capillaries were extracted from AONCO images, enhanced using the Gabor filter, the vesselness filter, and the Hough transform. A total of 43 capillary segments (each 50 µm long) were analyzed in 12 eyes of 12 subjects, and the measurement error of the automated method was 0.09 cell over 50 µm compared with results obtained by manual counting. Our method provides a tool for assessing RBC spatial distribution in retinal capillaries.

Published: June 2021

Herein, a flexible four-dimensional optical data storage technique is demonstrated by harnessing ultrafast laser-induced fluorophores in thermoplastic polyurethane. By modulating the pulse energy of a 515 nm laser, data voxels with multilevel fluorescence signals can be generated and encoded. The readout accuracy of the encoded multilayer information remains at 92.2% after 50 bending cycles, demonstrating the feasibility of our technology for data recording based on a roll-to-roll method. The generation of fluorophores by only a single femtosecond laser pulse provides the ability to record data beyond 20 MB/s.

Published: June 2021

Background
Informed consent (IC) is a healthcare standard emphasizing the meaning of human dignity as clarified in the Universal Declaration of Human Rights. Data about IC practices in Egypt is insufficient. This study aimed to assess the Egyptian patients’/guardians’ experiences about IC and their expectations about its practices’ purposes in general and according to the type of the healthcare facility.

Methods
Self-administered questionnaire was carried out for 1092 participants who had undergone or were scheduled to a procedure requiring an IC at three studied types for Egyptian health care facilities. Ten statements were ranked twice by the participants to reflect their perception of IC purpose as per what is currently practiced and what they believe should be practiced.

Results
IC implementation varies significantly (p<0.05) across the health care facilities in Egypt. The percentage of its implementation at the non-governmental facilities, governmental facilities, and university hospital was 85.9%, 77.8%, and 63.8 respectively. The first three ranked purposes of the current IC practices were: “Helping patient/guardian decide (64.9%)”, “Documenting patient’s/guardian’s decision (59.3%)”, and “Having shared decision (57.3%)”. The perceived purposes of IC to be practiced were: “Informing the patient/guardian (68.4%)”, “Making sure patient/guardian understand (65.3%)” and “Documenting patients/guardians decisions (65.1%)”. “Being a meaningless routine” was reported by the majority to be ranked as a low purpose for IC current and preferred practices.

Conclusion
The practice of IC is common within the Egyptian medical community. Participants believe that information disclosure “Making sure patients understand” has to help in IC decision making and its main purpose. However, unfortunately, this is not perceived as a current purpose of IC. There was consensus agreement that documenting the patient’s/guardian’s decision and informing the patient/guardian are perceived as both important current and preferred purposes for IC practices.

Published: June 2021

BackgroundThere is a worrying lack of epidemiological data on the sex differential in COVID-19 infection and death rates between the regions of Peru.MethodsUsing cases and death data from the national population-based surveillance system of Peru, we estimated incidence, mortality and fatality, stratified by sex, age and geographic distribution (per 100,000 habitants) from March 16 to November 27, 2020. At the same time, we calculated the risk of COVID-19 death.ResultsDuring the study period, 961894 cases and 35913 deaths were reported in Peru. Men had a twofold higher risk of COVID-19 death within the overall population of Peru (odds ratio (OR), 2.11; confidence interval (CI) 95%; 2.06–2.16;p<0.00001), as well as 20 regions of Peru, compared to women (p<0.05). There were variations in incidence, mortality and fatality rates stratified by sex, age, and region. The incidence rate was higher among men than among women (3079 vs. 2819 per 100,000 habitants, respectively). The mortality rate was two times higher in males than in females (153 vs. 68 per 100,000 habitants, respectively). The mortality rates increased with age, and were high in men 60 years of age or older. The fatality rate was two times higher in men than in women (4.96% vs. 2.41%, respectively), and was high in men 50 years of age or older.ConclusionsThese findings show the higher incidence, mortality and fatality rates among men than among women from Peru. These rates vary widely by region, and men are at greater risk of COVID-19 death. In addition, the mortality and fatality rates increased with age, and were most predominant in men 50 years of age or older.

AbstractThe correct individual tree segmentation of the forest is necessary for extracting the additional information of trees, such as tree height, crown width, and other tree parameters. With the development of LiDAR technology, the research method of individual tree segmentation based on point cloud data has become a focus of the research community. In this work, the research area is located in an underground coal mine in Shenmu City, Shaanxi Province, China. Vegetation information with and without leaves in this coal mining area are obtained with airborne LiDAR to conduct the research. In this study, we propose hybrid clustering technique by combining DBSCAN and K-means for segmenting individual trees based on airborne LiDAR point cloud data. First, the point cloud data are processed for denoising and filtering. Then, the pre-processed data are projected to the XOY plane for DBSCAN clustering. The number and coordinates of clustering centers are obtained, which are used as an input for K-means clustering algorithm. Finally, the results of individual tree segmentation of the forest in the mining area are obtained. The simulation results and analysis show that the new method proposed in this paper outperforms other methods in forest segmentation in mining area. This provides effective technical support and data reference for the study of forest in mining areas.
Reportage 4.0
Authors: Retzlaff Stefanie 
Published: June 2021

Abstract
The article illuminates Heike Geißler’s book Saisonarbeit’s relation to the tradition of the reportage genre since the 19th century, and shows why this genre is of current relevance, especially in view of the latest restructuring of work. Although talk of the widespread digitalization of labor implies a fundamental transformation of its conditions, the mail-order business represented in Saisonarbeit tends to evoke reminiscences of past phases of capitalist production. It is precisely here that the reportage has a special function as a report of vivid experiences.

Abstract
While autobiographical research in literary studies has recently focused mainly on aesthetic and theoretical aspects (for example, in the discussion of ‘autofiction’), this article focuses on the variety of autobiographical writing at the present time. It provides an outline of the autobiographical genre spectrum linked to the three principal purposes (truth, coherence, therapy), which regulate the ‘autobiographical desire’ at the beginning of the 21st century.

Abstract
The Venetian incunabula and post-incunabula traced in the library of the Nuremberg humanist Willibald Pirckheimer express the significant influence of the two cities’ relationship on shaping early modern culture in North-alpine Europe: The books, traded by Franconian merchants as luxury goods and, due to the miniatures added by Albrecht Dürer, examples of the influence of Italian Renaissance art north of the Alpes, also shaped the development of Greek humanism in the north and played an important role in constituting learned networks. The ambivalent and always shifting relation of their status as luxury goods or as objects of intellectual knowledge continued after Pirckheimer’s death as they became part of important English book collections and in the 1920 s precious pieces of the stocks of the famous Munich antiquarians Jacques and Erwin Rosenthal, the latter studying as an art historian the artistic importance of Dürer’s miniatures in Pirckheimer’s Venetian books.

Abstract

Objectives
Hashimoto’s thyroiditis (HT) is the most common cause of goiter and acquired hypothyroidism in children and adolescents, especially in areas without endemic iodine deficiency. We aimed to evaluate the follow-up results of children and adolescents diagnosed with HT, including clinical, biochemical, and radiological findings and treatment approaches.

Methods
HT patients, who were diagnosed between 2012 and 2018 years in a single-center, were assessed retrospectively.

Results
Two hundred and twenty-four cases were included in the study, 75.9% of whom were girls (female/male ratio: 3.1) and 66.5% were pubertal. The median age of the cases at first admission was 12.5 (9.2–15) years. The median follow-up period of 196 patients, who continued their follow-up regularly, was 2.1 (0.7–4.8) years. When autoantibody levels were analyzed according to gender, mean anti-Tg levels were higher in girls (p=0.028), whereas anti-TPO levels were similar (p=0.372). A nodule was detected in the ultrasonographic follow-up of 29 (13%) patients. Papillary thyroid carcinoma was observed in 10.3% (n=3) of those with nodules. When the last ultrasonography findings of 188 patients with available radiological follow-up data were compared with their initial evaluation, the rate of heterogeneous parenchymal echogenicity increased significantly (p=0.008). The need for l-thyroxine dosage augmented over time.

Conclusions
Although HT is more common in adolescent girls, it can be encountered in both genders and at all ages in childhood. The incidence of malignancy was not higher in patients with nodules associated with HT than the reported incidences of malignancy in nodules not associated with HT.
I “mali futuri” e non solo: possibili riprese tucididee in Dexippo e Eliodoro
Authors: Cerroni Enrico 
Published: June 2021

Abstract
The reception of the work of Thucydides in late antique authors constitutes a huge chapter of allusions and reworkings, on methodological, structural, lexical levels and more. A fortiori, certain particularly famous passages by the historian are well suited for a study of their reception, above all where key terms or rare expressions are concentrated. The case of the adjective ἀλγεινός, a poeticism declined twice in the epitaphios of Pericles (2.39 and 2.43) offers interesting material of this kind in the work of Dexippus, the Athenian historian of the third century A.D., and in the romance author Heliodorus. Alongside a secure reference to 2.39 in Dexippus (F28 Martin = F34 Mecella), already identified by Stein, it is possible to identify a further reuse in another fragment, probably extracted from a demegoria (F26b Martin = F32b Mecella). In the light of these examples, it becomes more likely that we can see a reminiscence of Thucydides also in a passage of Heliodorus of Emesa (5.29), already proposed by van Krevelen but omitted from the repertory of citations present in the Aethiopica prepared by Feuillâtre.
Σαλμεσχ(ο)ινιακά: Measurement Standards of Astrotheology?

Published: June 2021

Summary
The meaning and the reference of the obscure term Σαλμεσχ(ο)ινιακά has been on debate more than a century among the scholars. In this article we try to unroll the thread of the research regarding the term, to detect and explain the context in which is referred, to solve the mystery of its etymology and to propose a brand new semantic core, which characterizes a whole stream of esoteric traditions, indicating the anthropomorphical representation of the deity, by giving the ecstatic description of its astral body and the measurement of its enormous and cosmic dimensions.
Investigation and Experimentation on Ancient Egyptian Tattooing Methods
Authors: Pászik Jenny 
Published: June 2021

Summary
The aim of this research is to use experimental archaeology and comparative studies in order to obtain a potential answer to the theory that UC 7790 is a set of tattooing implements. Comparing the tools, methods, and inks of other cultures that practice tattooing is a way to offer some guidance regarding the identification of tattooing tools in the archaeological record. The experiment reproduced the original points using the closest modern metal and tested each one with an organic mixture of charcoal and water, and Indian ink as a control ink. The reproduced needles are tested on pigskin and human skin to test efficacy and healing. The experiment proves that UC 7790 may have been tattoo needles as they successfully tattoo human skin and were probably hafted implements.
The Birth of Modern Jewish Theology: Reactions to Bruno Bauer’s Secular Supersessionism
Authors: Kohler George Yaakov 
Published: June 2021

Abstract
Jüdische Gelehrte reagierten auf Bruno Bauers antisemitisches Pamphlet Die Judenfrage (1842) auf ganz verschiedene Weise. Gemeinsam war allen Antworten jedoch die Annahme, dass die Mission des Judentums an Kultur und Humanität noch nicht erfüllt ist und auch nicht vom Christentum allein erfüllt werden kann. Nur der mosaische Monotheismus war dazu bestimmt, „den zivilisierten Nationen eine moralische Grundlage zu geben“, wie Gotthold Salomon, einer der in diesem Aufsatz behandelten Denker, gegen Bauer schrieb. Andere Disputanten, wie Hermann Jellinek, behaupteten sogar eine absolute theologische Überlegenheit des Judentums gegenüber der halb-paganen christlichen Religion, wieder andere, wie der Luxemburger Oberrabbiner Samuel Hirsch, sahen im Judentum zumindest das bessere, das essentiellere Christentum. Keiner der jüdischen Gegner Bauers jedoch war mit dessen These einverstanden, dass es sich beim Judentum um ein überholtes Religionsmodell handelte, das nur noch künstlich von einigen halsstarrigen Traditionalisten am Leben gehalten wird. Ob die jüdischen Theologen Bauer als moralisch gefährlichen Atheisten oder eher als Hegelianischen Wiederbeleber der alten christlichen Substitutionslehre sahen, die hier besprochene öffentliche Debatte mit Bauer gab ihnen eine willkommene Gelegenheit – möglicherweise sogar zum allerersten Mal – den genauen Ort des Judentums innerhalb der Entwicklung der kulturellen Idee der Religion in der Weltgeschichte zu bestimmen.
Theodor Heuss „Zu Ernst Troeltschs Gedächtnis“. Eine Gedenkrede im „Demokratischen Klub Berlin“
Authors: Graf Friedrich Wilhelm 
Published: June 2021

Abstract
On September 12, 1949, the liberal politician Theodor Heuss, party leader of the „Freie Demokratische Partei“ (FDP), was elected by the Bundesversammlung (Federal Convention) as the first Bundespräsident, i. e. head of state, of the newly founded Bundesrepublik Deutschland. As a young man Heuss had been a close friend and political ally of Friedrich Naumann, the protestant pastor and left wing liberal politician, supported by Ernst Troeltsch. Heuss then working as a political journalist for liberal newspapers and Naumann’s weekly journal Die Hilfe, was an admirer of Troeltsch, and since 1910 they often met in Heidelberg, at Villa Fallenstein, Ziegelhäuser Landstraße 17, where Max and Marianne Weber as well als the Troeltschs lived; Heuss frequently visited Max Weber’s Sunday jour fixe. When in 1915 Troeltsch became a professor at the Philosophical Faculty of Berlin University Heuss regularly kept in contact with him especially through Hans Delbrück’s „Mittwochabend“, a weekly gathering of liberal intellectuals, professors, politicians and journalists discussing political reforms and the ongoing war. Both Troeltsch and Heuss, 19 years younger, demanded the democratization of the Deutsches Reich, and after the end of the war and the revolution of 1918/19 they became members of the newly founded left wing liberal party „Deutsche Demokratische Partei“ (DDP). After Troeltsch’s sudden death on February 1st, 1923, Heuss wrote an obituary, and, together with his wife Elly Heuss-Knapp, attended the funeral service conducted by Adolf von Harnack. Heuss was a member of the „Demokratischer Klub Berlin“, founded in 1919 by liberal politicians, bankers and academics to regularly discuss the political situation of the new democratic state, the Weimar Republic. Unknown until now, seven weeks after Troeltsch’s death the „Demokratische Klub“ invited its members (the club only had male mebers!) to a memorial act for Troeltsch. On this occasion Heuss delivered a speech „Zu Ernst Troeltschs Gedächtnis“ („To the Memory of Ernst Troeltsch“) which is published here for the first time.

AbstractWidespread introduction of HIV integrase inhibitors into clinical care may result in appearance of drug resistance mutations affecting treatment outcome. The aim of our study was to monitor the resistance patterns of integrase inhibitors beside protease and reverse transcriptase inhibitors in newly diagnosed therapy-naive HIV-positive patients in Hungary between 2017 and 2019.Genotype-based resistance testing of HIV integrase, protease and reverse transcriptase was performed by amplification and Sanger population sequencing from plasma samples. Drug resistance mutations were identified by the algorithm of Stanford HIV Drug Resistance Database.Potentially transmitted, non-polymorphic integrase major mutation was detected in 1 out of 249 samples, while accessory mutations were observed in further 31 patients (12.4%). The overall prevalence of transmitted drug resistance (TDR) mutations related to protease and reverse transcriptase inhibitors was 5.8% (10/173) between the end of 2017 and 2019. Nucleoside reverse transcriptase inhibitor associated resistance mutations were the most frequent indicators of TDR (6/173; 3.5%), followed by resistance mutations associated with protease (3/173; 1.7%) and non-nucleoside reverse transcriptase inhibitors (2/173, 1.2%).The first detection of integrase major mutation and the changing patterns of other resistance mutations in Hungarian untreated HIV-positive population indicate the necessity of continuous molecular surveillance of Hungarian HIV epidemic.
