Risiko- und Schutzfaktoren im Kontext von Radikalisierung und extremistischer Gewalt. Themenübersicht und Implikationen für die Wissenschaft und Praxis
Authors: Rau Thea
Published: May 2021

Obwohl die Betrachtung von Risiko- und Schutzfaktoren im Hinblick auf extremistische Gewalt Hinweise darauf geben kann, welche Personen besonders gefährdet sind, sich zu radikalisieren, ist die evidenzbasierte Studienlage zu diesem Themenbereich „dünn“. Die folgende Arbeit stellt die Ergebnisse einer systematischen Literaturrecherche zu diesem Thema vor, die insgesamt 31 relevante Studien umfasst und diskutiert kritisch deren Aussagekraft. Fazit der Analyse ist, dass die in den Studien genannten Risiko- und Schutzfaktoren sehr unspezifisch sind. Sie können jedoch erste Hinweise geben, worauf Fachkräfte in der präventiven Arbeit achten sollten. Daneben können sie Anhaltspunkte dafür geben, welche insbesondere dynamischen Faktoren im Rahmen einer Deradikalisierungsarbeit mitberücksichtigt werden sollten. Weitere Implikationen lassen sich insbesondere für die Forschung ableiten. So benötigt es weitere Studien, um Risiko- und Schutzfaktoren besser erfassen zu können.

The Challenge of Implementing Preferred Gender Pronouns: Queer Autonomy in the Age of Information Technologies
Authors: Pook Zooey Sophia
Published: May 2021

A preferred gender pronoun or PGP is the gender pronoun, or set of gender pronouns, an individual uses to represent themselves and by which they would like others to use when they represent them (PFLAG). The use of PGPs is meant to show respect to the autonomy of individuals whose gender identity may not conform to the appearance of others, or individuals whose identity is gender non-binary (HRC). The use of PGPs is suggested as a best practice by nearly every major LGBT+ organization in the US (PFLAG, HRC, etc.). Today, systems for implementing PGPs exist everywhere from college applications, hospital intake forms, dating websites, and beyond. While the use of PGPs shows respect for transgender and gender nonconforming individuals, these practices have unintended consequences as they contribute to the ever-expanding economies of data collection, made possible through the rise of information technologies. This work will explore questions of economy and power related to the collection of PGPs and the challenge of queer autonomy in the age of neoliberal capitalism.

Published: May 2021

The article is dedicated to the study of the conversion of cases of anorexia syndrome to bulimia nervosa and to schizophrenic spectrum disorders, as well as to the contribution of neuropsychological parameters on the clinical findings of mental and behavioral disorders. The analysis of literature sources reveals that it is anorexia nervosa that most clearly demonstrates the thinness of the line between the variants of a normal and pathological mental state. The authors consider this problem taking into account the current knowledge regarding anorexia syndrome. This paper provides the results of a study that involved 65 female patients (the age, the median Me (25-75%) was 20 (17-24) years old) suffering from anorexia nervosa, whose 5-year follow-up diagnosis was changed to bulimia nervosa (20 people) or schizophrenic spectrum disorders (5 people). We also spotted the difference in the time required to diagnose a case (of anorexia nervosa) depending on the presence or absence of a change in the diagnosis to bulimia nervosa in a 5-year follow-up, using the Kaplan-Meier method.

Authors:   Belarusian State Medical University, Kozyro I.A. , Sukalo A.V. ,   Belarusian State Medical University, Mirilenko A.P.
Published: May 2021

Purpose of the study: to determine the rate of progression of primary chronic glomerulopathies (GP) in children and to establish the main risk factors for the development of this process. Materials and methods. 188 children who were under observation and treatment at the Republican Center for Pediatric Nephrology and Renal Replacement Therapy of the "2nd Children's City Clinical Hospital" in Minsk, aged 3 to 17 years, with morphologically verified kidney damage, were included in the study: group №1 - children with minimal change disease (MCD), n=53; group №2 with IgM nephropathy (IgMN), n=26; group №3 with focal segmental glomerulosclerosis (FSGS), n=55; group №4 with IgA nephropathy (IgAN), n=54.The duration of the period from the onset of the disease to reaching the 3rd stage of CKD and predictors that determine the rate of progression of GP using Kaplan-Meier method was studied. Results. Anamnestic, clinical, laboratory, immunological (blood concentration of markers of T and B lymphocyte activation RANTES and BAFF), proinflammatory (caspase 1, IL1β and TNFα), vascular (VEGF) and tissue (TGF1β) growth factors), metabolic status (adiponectin, leptin, obestatin, vitamin D 25 (OH) D), instrumental, morphological changes were analyzed. Each of the variables was considered as a likely risk factor for the progression of GP. Conclusion. A mathematical model has been developed for predicting the risk of progression of secondary GP in children, including risk factors as predictors: impaired renal function at the onset of the disease, non-compliance with therapy, and a decrease in the estimated glomerular filtration rate (eGFR) at the onset of the disease less than 87 ml/min. The predictive accuracy of the model was 90,9% (95%ДИ 79,3-100%).

Published: May 2021

Staple line and anastomotic leakage is frequent and threatening complication of bariatric surgery. Its early diagnostics is difficult, and search for new diagnostic criteria is necessary. Objective. To improve post-bariatric staple line and anastomotic leakage diagnostics by revealing new early diagnostic criteria. Materials and methods. Following hypothesis considered: postoperative stab neutrophils level is early sign of staple line and anastomotic leakage after bariatric surgery. Retrospective comparative study performed to test the hypothesis. Study group consisted of patients with staple line and anastomotic leakage in postoperative period (n=9). Control group consisted of patients with uncomplicated postoperative period (n=253). ROC-curves for stab neutrophils levels in 12 and 36 hours after surgery analyzed in both groups. The reference method was a comprehensive dynamic examination. Results. Area under the ROC-curve for stab neutrophils in 36 hours (AUC=0,613) was higher, than area under ROC-curve for stab neutrophils in 12 hours (AUC= 0,543). So stab neutrophils in 36 hours is more sensitive and specific early diagnostic criterion for staple line and anastomotic leakage. Sensitivity Se=55,56% and specificity Sp=72,13% achieved at the stab neutrophils in 36 hours after surgery level above 9%. Conclusion. As staple line and anastomotic leakage early diagnostic criterion stab neutrophils level in 36 hours after bariatric surgery has high specificity. Proposed criterion available in early postoperative period, when signs of leakage are obscured. In combination with other methods it promotes staple line and anastomotic leakage earlier diagnostics, what improve patients’ treatment results.
Adoption of non-Chinese Names as Identity Markers of Chinese International Students in Japan
Authors: Chen Jinyan
Published: May 2021

This study explores naming practices among Chinese international students and their relation to personal identity during their sojourn in Japan. Although previous studies have reported that some Chinese international students in English-speaking countries adopt names of Western origin (Cotterill 2020; Diao 2014; Edwards 2006), participants in this study were found to exhibit different naming practices: either adopting names of Japanese or Western origin; or retaining both Western and Japanese names. Drawing on fifteen semi-structured interviews with Mainland Han Chinese students, this investigation examines their motivations for adopting non-Chinese names and determines how personal identities are presented through them. The qualitative analysis reveals that the practice of adopting non-Chinese names is influenced by teacher-student power relations, Chinese conventions for terms of address, pronunciation, and context- sensitivity of personal names. As will be shown in this article, through the respondents’ years of self-exploration, their self-adopted non-Chinese names gradually became internalized personal identity markers that allow the bearers to explore and exhibit personality traits, which might not have been as easily displayed via their Chinese given names.
A great, upwelling flux of mutability: Failure and error in Eve Kosofsky Sedgwick’s A Dialogue on Love
Authors: Hanman Siegersma Frankie
Published: May 2021

How might we think of the creative potential of error when we bear witness to ourselves? Could we think of stumbling as mistakenly finding our space of possibility? How might we suggest a praxis of error and failure as messy, sexy, cognitively powerful energy? This paper takes up A Dialogue on Love (2000) by Eve Kosofsky Sedgwick, a hybrid nonfiction account of a therapeutic relationship, to examine relationality and care in the making of poetic errors to encourage us toward new trajectories. I work with Anne Carson’s suggestion that error in poetry is generative (2000), use Jack Halberstam’s possibilities of queer failure (2011) and integrate Audre Lorde’s reflections on her experience with breast cancer in The Cancer Journals (1980). Sara Ahmed’s theorisation of the feminist killjoy (2017) provides an opportunity for thinking through mistakenness and error as pressing for social change and questioning of power structures. With the assistance of these texts, I lean into the generative qualities of A Dialogue onLove, centring Sedgwick’s playfulness, attention to pleasure and love as she bears witness to herself in language.
What is close: objects as creation of adoption belongings
Authors: Rogers Christine , Fulton Laura
Published: May 2021

(Verrier 1993); however, precious objects can help alleviate these feelings. Russell Belk (1998) argues that some objects come to be seen as part of the self. For writers Christine Rogers and Laura Fulton, a handkerchief taken from a birthfather, and a teddy bear gifted by a special uncle, helped create belonging and connection. In this article, Rogers and Fulton introduce their cherished objects and explore the complex layers of attachment that their items generate and express. Rogers and Fulton argue that these things are haunted (Brown, Reavey & Brookfield 2014), invested with power and rich with meaning. For Rogers, the stolen handkerchief expresses her fear that the attachment to her birthfather was not stable or permanent, and embroidering the handkerchief acknowledged and helped transform this adoption fear. For Fulton, a teddy bear was the conduit for her complex thoughts and feelings when she was brought into a new family as a toddler. It was the bear who helped her storytelling practices, which were a way of addressing and understanding the silence and loss of her adoption.

Regeneration of submediterranean species Euonymus latifolius (L.) Mill. at its southernmost limit in Europe
Authors: Agea Daniel , García-de Lucas Sandra , Lorite Juan
Published: May 2021

Due to the ongoing effects of climate change in the Mediterranean (increasing temperature and decreasing rainfall), conditions for Submediterranean species are disappearing as their habitats are dwindling. We have focused on Euonymus latifolius (L.) Mill., a nemoral-Submediterranean species, at its southernmost populations of Europe. The aim was to evaluate the population structure and regeneration niche of the species at microhabitat scale. We selected five larger populations among the 13 existing ones, marking 25-30 individuals per population. We measured twice: height, width, vegetation cover, survival, soil moisture and temperature. As result, we provided data of the 13 existing populations, containing 93 adults and 350 juveniles.

Moreover, we have obtained a very skew population structure with a low number of recruits for five selected populations, especially at smaller populations. Most E. latifolius juveniles were encountered under dense tree canopy (more than 80 % in cover) formed by a mixture of Submediterranean and Mediterranean species. Biovolume per population showed significant differences among the main populations CP and CV, presenting this last a higher recruitment, while recruitment was very low in general. For soil parameters, we found a critical role of canopy, which showed a positive effect on juvenile microhabitat (higher moisture and lower soil temperature).

The results showed us the critical situation of the species, with very fragmented populations, low number of individuals, and scattered spatial patterns of individuals within the populations. Also, survival problems, a non-balance demographic structure, and regeneration problems were detected. Finally, we propose a sere of conservation measures, from monitoring to active measures (key tree species plantation, reintroduction, reinforcements), combined with threat control (herbivory, pests, and impact from outdoor activities). All combined may help to preserve this species at its southernmost populations.

In-vitro Response of Cereal Aphid Sitobion avenae (Homoptera: Aphididae) against some Selected Botanical Extracts
Authors: Rehan Khalid Muhammad
Published: May 2021

Cereal aphid, Sitobion avenae (Homoptera: Aphididae), is one of the destructive pests of
wheat and other crops around the globe. Irrational utilization of highly toxic synthetic
chemicals against this particular pest has led to several issues of health and environment. In such case, there is a need to find out the control measures, which are less toxic and friendly to environment. The present study was aimed to evaluate the effectiveness of aqueous extracts of four indigenous plants, i.e. akk (Calotropis procera), lemon (Citrus limon), neem (Azadirachta indica) and dhatura (Datura alba), against S. avenae in laboratory conditions. Toxicity bioassays were conducted according to Completely Randomized Design using 2% aqueous extracts with three replications. Results showed a differential response of aphids to all botanical extracts. Aphid mortality increased with the exposure time with maximum values (i.e. 39.52, 31.75, 26.76 and 24.07% for A. indica, C. procera, C. limon and D. alba extracts, respectively) recorded at 72 h posttreatment. Similarly, A. indica extract exhibited minimum fecundity (2.67 offspring per adult) and adult body weight (340.09 µg) and maximum nymphal development time (9.32 days), followed by C. procera, C. limon and D. alba. Overall study results suggest that A. indica and C. procera extracts would be effective botanical options for combating aphid infestations on wheat and other cereal crops

The action of the Cameroonian judge in the context of the preservation of land ownership faced with the right of pre-emption remains very marginal. On the other hand, thanks to the increase in its field of competence, the administrative judge has been erected as a full-fledged protector of the property of private persons subject to pre-emption. Through his action, the administrative judge should ensure that land pre-emption operations comply with the law. In the event of non-compliance with legality, the respondent could be held liable. Moreover, the Cameroonian legal system reserves a traditional place for the judicial judge in the protection of pre-empted land ownership, as he contributes through his office to counter any infringement of land ownership. The judicial judge's field of competence could have been broadened with the possibility of carrying out legality control of land pre-emption operations, but this attribution of competence remains very clearly defined.

Published: May 2021

The purpose of this study is to establish Novel Zero-order UV-Spectrophotometric - absorbance and Zero Order- Area under curve (AUC) methods for estimation of Fenticonazole Nitrate in bulk and vaginal capsules with the application of hydrotropic solubilization phenomenon. Fenticonazole Nitrate is an antifungal drug and it is completely insoluble in water. Pluronic F127 (10% w/v) solution was used as solvent for solubilization of Fenticonazole Nitrate. Maximum absorption for Fenticonazole Nitrate was found to be at wavelength 253nm when dissolved in Pluronic F127 (10% w/v) solution. The methods are based upon measurement of absorbance at 253nm and integration of area under curve for analysis of Fenticonazole Nitrate in the wavelength range of 242.2-261.6nm. The drug followed linearity in the concentration range of 8 - 40µg/mL with correlation coefficient value r2> 0.99 for both methods. The proposed methods were validated for accuracy (% recovery), precision, repeatability and ruggedness, as per ICH guidelines. The proposed methods were applied for qualitative and quantitative estimation of Fenticonazole Nitrate in vaginal capsules and results were found in good agreement with the label claimed. Developed methods can be used for routine analysis of Fenticonazole Nitrate in bulk and Vaginal Capsules.

Authors: Anh Thu Nguyen
Published: May 2021

Quantification of acetaminophen, caffeine and ibuprofen in ternary mixtures was studied by using UV spectroscopy coupled with multivariate analysis [tri-linear regression-calibration (TLRC), classical least squares (CLS) and multi linear regression calibration (MLRC)]. To validate UV spectroscopic methods, the wavelength range of 215 – 290nm and a matrix (composed of 21 standard solutions containing acetaminophen 20-32.5mg/L, caffeine 1-3.5mg/L and ibuprofen 12-32mg/L) were selected. With the exception of TLRC, CLS and MLRS algorithms proved to be relevant for obtaining UV spectroscopic assay results and dissolution profile of acetaminophen, caffeine and ibuprofen in their combined capsules and tablets, with precision (RSD < 3%) and accuracy (98.3 – 101.9% recovery). It is also suggested that these UV spectroscopic methods could replace UHPLC analysis in the routine quality control of these compounds in their solid pharmaceutical dosage forms (p > 0.05).

The control of potentially mutagenic and carcinogenic impurities in pharmaceutical products is key importance in evaluating carcinogenic risk to humans. The recent discovery of nitrosamine impurities in some marketed pharmaceuticals has increased the risk of their mutagenic and carcinogenic potential. According to the International Agency for Research on Cancer (IARC), nitrosamine is the chemical classified as a probable human carcinogen. Nitrosamine impurities are known to be mutagenic and carcinogenic, very small exposure of these impurities can lead to cancer. These impurities may be produced and get incorporated into drug substances or drug products by a reagent, catalyst, solvent, or raw materials used in the process of manufacturing. The presence of nitrosamine impurities in angiotensin II receptor blocker (ARB) drugs containing tetrazole ring has caused worldwide product recalls. The various regulatory authorities have published the press release or notice regarding the control of these impurities with the interim limit. In 2007, the European medicines agency (EMA) suspended the marketing authorization of Viracept, because of the presence of elevated levels of ethyl methane sulfonate, in the drug product. Validated analytical methods are used to identify and quantify these impurities to the trace level at a given interim limit.
An Editorial Anomaly
Authors: Blesa Miguel Ángel
Published: May 2021

Most of the science in the Latin-American region is funded with public money, and the institutions that provide the money have little or no record of the resulting published material. In a time when the open access initiative is gaining momentum and is advocated by financing institutions, the Argentine Association for the Progress of Science (AAPC) evaluated that launching a new publication was warranted, with distinctive features that make it an editorial anomaly.

Published: May 2021

An overview of arsenic (As) presence in waters in Latin America (LA) is presented. Aspects on As occurrence, effects of As on human health, regulations regarding the maximum allowable concentration of As in drinking water, analytical techniques for As determination, and conventional/emerging technologies for As removal developed in LA are mentioned. Arsenic presence has been identified in many LA countries in a range of concentrations, originated from various sources; however, its origin is mainly natural. Main analytical techniques available in LA laboratories are described. Pathologies derived from the chronic consumption of As, the metabolism of As in the human body and the effects of the different As chemical forms are detailed. A list of conventional and emerging technologies for As removal in LA waters for human consumption, for large, medium and small populations, rural and periurban, is reported. Conclusions and recommendations to face the problem are included.

We present procedures for determining the nature of charge-transfer excited states in transition metal complexes relevant to energy conversion and chemical sensing processes. In particular, we analyze the importance of resorting to both spectroelectrochemical and photophysical techniques to elucidate the “fingerprints” of the intermediates involved in the fate of these reactions. Our contributions to the subject are discussed.
Studying Electron Transfer Pathways in Oxidoreductases
Authors: Rivas Maria Gabriela , Gonzalez Pablo Javier , Ferroni Felix Martin , Rizzi Alberto Claudio , Brondino Carlos
Published: May 2021

Oxidoreductases containing transition metal ions are widespread in nature and are essential for living organisms. The copper-containing nitrite reductase (NirK) and the molybdenum-containing aldehyde oxidoreductase (Aor) are typical examples of oxidoreductases. Metal ions in these enzymes are present either as mononuclear centers or organized into clusters and accomplish two main roles. One of them is to be the active site where the substrate is converted into product, and the other one is to serve as electron transfer center. Both enzymes transiently bind the substrate and an external electron donor/acceptor in NirK/Aor, respectively, at distinct protein points for them to exchange the electrons involved in the redox reaction. Electron exchange occurs through a specific intra-protein chemical pathway that connects the different enzyme metal cofactors. Based on the two oxidoreductases presented here, we describe how the different actors involved in the intra-protein electron transfer process can be characterized and studied employing molecular biology, spectroscopic, electrochemical, and structural techniques.
Modulation of Functional Features in Electron Transferring Metalloproteins
Authors: Murgida Daniel Horacio
Published: May 2021

Electron transferring metalloproteins are typically implicated in shuttling electrons between energy transduction chains membrane complexes, such as in (aerobic and anaerobic) respiration and photosynthesis, among other functions. The thermodynamic and kinetic electron transfer parameters of the different metalloproteins need to be adjusted in each case to the specific demands, which can be quite diverse among organisms. Notably, biology utilizes very few metals, essentially iron and copper, to cover this broad range of redox needs imposed by biodiversity. Here, I will describe some crucial structural and dynamical characteristics that modulate the electron transfer parameters (and alternative functions) of two prototypical metalloproteins: the iron protein cytochrome c and its redox partner, the CuA center of the terminal respiratory enzyme cytochrome c oxidase. Specifically, I will focus on summarizing results obtained in recent years in my laboratory.
Morphology-dependent Photophysical Properties of Poly-4-vinylpyridine Polymers Containing –Re(CO)3(N^N)+ Pendants
Authors: Wolcan Ezequiel
Published: May 2021

We review the morphological and the photophysical properties of several inorganic polymers that can be prepared from poly-4- vinylpyridine (P4VP). These polymers contain –Re(CO)3(N^N)+ pendants attached to their backbone with α-diimine ligands (N^N) such as 2,2´-bipyridine (bpy), 1,10-phenanthroline (phen), 3,4,7,8-tetramethyl-1,10-phenanthroline (tmphen) and 5-nitro-1,10- phenanthroline (NO2-phen). These Re(I) polymers, show marked differences in their photophysical properties when compared to single [pyRe(CO)3(N^N)]+ molecules in diluted solutions. For example, Re→phen charge transfer excited states (MLCT) in the Re(I) polymers undergo a more efficient annihilation and/or secondary photolysis than in [pyRe(CO)3phen]+ complexes. Depending on solvent and/or cast film conditions, several aggregates of polymer strands with different morphologies were observed by transmission electron microscopy (TEM) and dynamic light scattering (DLS) techniques. Morphological changes derived from media-imposed changes (solvent, temperature) or from polymer backbone chemical modifications (protonation or peralkylation in P4VP uncoordinated pyridines) are responsible for the marked differences observed between the photophysical properties of these Re(I) polymers and those of the single pyRe(CO)3(N^N)+ molecules. Therefore, these Re(I) polymers can provide a good reaction scenario for other photochemical reactions. Thus, resonance energy transfer between –Re(CO)3(tmphen)+ and –Re(CO)3 (NO2-phen)+ pendants was observed in Re(I)-P4VP polymers containing both chromophores attached to their backbone. In addition, in the quenching of the MLCT luminescence of –Re(CO)3(N^N)+ pendants by amines, we observed a retardation of the molecular motion due to the restricted media that favored the observation of the Marcus inverted effect in bimolecular reactions due to the fact that low values of the solvent reorganization energies are achieved within aggregates.
Big Science for the Small World

Published: May 2021

In these strange days of confinement and health emergency, the quality of Argentine Science stands as a strong, comforting light even for those who had never been seduced by scientific research before. And it is like a paradox that the invisible, the small, the nanometric, attracts our attention even more than the big world, showing that, oftentimes, what is essential is (certainly!) invisible to eyes.

Endogenous lectins play key roles in cell homeostasis by decoding the information encrypted in glycans present on the cell surface or extracellular matrix. Galectins, a family of soluble lectins, have emerged as central regulators of innate and adaptive immune responses. In this article, we review seminal work demonstrating the immunoregulatory roles of Galectin-1 (Gal-1), a proto-type member of the galectin family, and highlight central mechanisms that control its functions in cancer and autoimmune inflammation. Understanding the cellular pathways that control Gal-1 expression and function in tumor and inflammatory microenvironments will set the bases for the design of rational therapies based on positive or negative modulation of this endogenous lectin in cancer and autoimmune diseases.
