Cooperation/Competition between Halogen Bonds and Hydrogen Bonds in Complexes of 2,6-Diaminopyridines and X-CY3 (X = Cl, Br; Y = H, F)
Authors: Bankiewicz Barbara , Palusiak Marcin
Published: April 2021

The DFT calculations have been performed on a series of two-element complexes formed by substituted 2,6-diaminopyridine (R−PDA) and pyridine (R−Pyr) with X−CY3 molecules (where X = Cl, Br and Y = H, F). The primary aim of this study was to examine the intermolecular hydrogen and halogen bonds in the condition of their mutual coexistence. Symmetry/antisymmetry of the interrelation between three individual interactions is addressed. It appears that halogen bonds play the main role in the stabilization of the structures of the selected systems. However, the occurrence of one or two hydrogen bonds was associated with the favourable geometry of the complexes. Moreover, the impact of different substituent groups attached in the para position to the aromatic ring of the 2,6-diaminopyridine and pyridine on the character of the intermolecular hydrogen and halogen bonds was examined. The results indicate that the presence of electron-donating substituents strengthens the bonds. In turn, the presence of electron-withdrawing substituents reduces the strength of halogen bonds. Additionally, when hydrogen and halogen bonds lose their leading role in the complex formation, the nonspecific electrostatic interactions between dipole moments take their place. Analysis was based on geometric, energetic, and topological parameters of the studied systems.
On the Emergence of Orientational Order in Folded Proteins with Implications for Allostery
Authors: Chakraborty Debayan , Mugnai Mauro Lorenzo , Thirumalai D.
Published: April 2021

The beautiful structures of single- and multi-domain proteins are clearly ordered in some fashion but cannot be readily classified using group theory methods that are successfully used to describe periodic crystals. For this reason, protein structures are considered to be aperiodic, and may have evolved this way for functional purposes, especially in instances that require a combination of softness and rigidity within the same molecule. By analyzing the solved protein structures, we show that orientational symmetry is broken in the aperiodic arrangement of the secondary structure elements (SSEs), which we deduce by calculating the nematic order parameter, P2. We find that the folded structures are nematic droplets with a broad distribution of P2. We argue that a non-zero value of P2, leads to an arrangement of the SSEs that can resist external forces, which is a requirement for allosteric proteins. Such proteins, which resist mechanical forces in some regions while being flexible in others, transmit signals from one region of the protein to another (action at a distance) in response to binding of ligands (oxygen, ATP, or other small molecules).
Deceased Donation Uterus Transplantation: A Review
Authors: Hammond-Browning Natasha , Yao Si Liang
Published: April 2021

Uterus transplantation (UTx) offers women with absolute uterine factor infertility the option to gestate and birth their own biologically related child. The first birth following living donation UTx happened in 2014. The first birth following deceased donation happened in December 2017, with further successes since. Interest in deceased donation UTx is increasing. The authors established a database to track UTx clinical trials and outcomes. Utilising this database and existing literature, this article reviews the first reported cases of deceased donation UTx and outcomes, and drawing upon comparisons with living donor UTx, comments upon the future for this area of reproductive transplantation research. This is the first article to bring together the literature on deceased donation UTx procedures and outcomes.

Among children born with laboratory-confirmed Zika virus (ZIKV) infection, visual impairment (VI) can occur despite normal ocular structure. The objective of this report is to describe ocular findings and visual function among children examined during the Department of Health Zika Health Brigade (ZHB) in the United States Virgin Islands in March 2018. This analysis is based on a retrospective chart review of children eligible to participate in the ZHB (i.e., part of the US Zika Pregnancy and Infant Registry) and who were examined by ophthalmologists. Eighty-eight children attended the ZHB. This report includes 81 children [48 (59.3%) males] whose charts were located [average gestational age = 37.6 weeks (range: 27.6–41.3) and average adjusted age at examination = 9.1 months (range: 0.9–21.9)]. Of those examined, 5/81 (6.2%) had microcephaly at birth, 2/81 (2.5%) had a structural eye abnormality, and 19/72 (26.4%) had VI. Among children with normal ocular structure and neurologic examination, 13/51 (25.5%) had VI. Despite a low incidence of abnormal ocular structure and microcephaly, about a quarter of children examined had VI. Our findings emphasize that ophthalmological examinations should be performed in all children with suspicion for antenatal ZIKV infection, even children with normal ocular structure and neurologic examination.
HDV Pathogenesis: Unravelling Ariadne’s Thread
Authors: Tseligka Eirini D. , Clément Sophie , Negro Francesco
Published: April 2021

Hepatitis Delta virus (HDV) lies in between satellite viruses and viroids, as its unique molecular characteristics and life cycle cannot categorize it according to the standard taxonomy norms for viruses. Being a satellite virus of hepatitis B virus (HBV), HDV requires HBV envelope glycoproteins for its infection cycle and its transmission. HDV pathogenesis varies and depends on the mode of HDV and HBV infection; a simultaneous HDV and HBV infection will lead to an acute hepatitis that will resolve spontaneously in the majority of patients, whereas an HDV super-infection of a chronic HBV carrier will mainly result in the establishment of a chronic HDV infection that may progress towards cirrhosis, liver decompensation, and hepatocellular carcinoma (HCC). With this review, we aim to unravel Ariadne’s thread into the labyrinth of acute and chronic HDV infection pathogenesis and will provide insights into the complexity of this exciting topic by detailing the different players and mechanisms that shape the clinical outcome.

Published: April 2021

Hand, foot, and mouth disease (HFMD) is a mild illness caused by enteroviruses (EV), although in some Asian countries, large outbreaks have been reported in the last 25 years, with a considerable incidence of neurological complications. This study describes epidemiological and clinical characteristics of EV infections involved in HFMD and other mucocutaneous symptoms from 2006 to 2020 in Spain. EV-positive samples from 368 patients were included. EV species A were identified in 85.1% of those typed EV. Coxsackievirus (CV) A6 was the prevalent serotype (60.9%), followed by EV-A71 (9.9%) and CVA16 (7.7%). Infections affected children (1–6 years old) mainly, and show seasonality with peaks in spring–summer and autumn. Clinical data indicated few cases of atypical HFMD as well as those with neurological complications (associated with the 2016 EV-A71 outbreak). Phylogenetic analysis of CVA6 VP1 sequences showed different sub-clusters circulating from 2010 to present. In conclusion, HFMD or exanthemas case reporting has increased in Spain in recent years, probably associated with an increase in circulation of CVA6, although they did not seem to show greater severity. However, EV surveillance in mucocutaneous manifestations should be improved to identify the emergence of new types or variants causing outbreaks and more severe pathologies.
Clinical Use of Improved Diagnostic Testing for Detection of Prion Disease
Authors: Figgie Mark P. , Appleby Brian S.
Published: April 2021

Prion diseases are difficult to recognize as many symptoms are shared among other neurologic pathologies and the full spectra of symptoms usually do not appear until late in the disease course. Additionally, many commonly used laboratory markers are non-specific to prion disease. The recent introduction of second-generation real time quaking induced conversion (RT-QuIC) has revolutionized pre-mortem diagnosis of prion disease due to its extremely high sensitivity and specificity. However, RT-QuIC does not provide prognostic data and has decreased diagnostic accuracy in some rarer, atypical prion diseases. The objective of this review is to provide an overview of the current clinical utility of fluid-based biomarkers, neurodiagnostic testing, and brain imaging in the diagnosis of prion disease and to suggest guidelines for their clinical use, with a focus on rarer prion diseases with atypical features. Recent advancements in laboratory-based testing and imaging criteria have shown improved diagnostic accuracy and prognostic potential in prion disease, but because these diagnostic tests are not sensitive in some prion disease subtypes and diagnostic test sensitivities are unknown in the event that CWD transmits to humans, it is important to continue investigations into the clinical utility of various testing modalities.
Macroscopic Traffic Simulation of Autonomous Vehicle Effects
Authors: Obaid Mohammed , Torok Arpad
Published: April 2021

The increasing worldwide demand on urban road transportation systems requires more restrictive measures and policies to reduce congestion, time delay and pollution. Autonomous vehicle mobility services, both shared and private, are possibly a good step towards a better road transportation future. This article aims to study the expected impact of private autonomous vehicles on road traffic parameters from a macroscopic level. The proposed methodology focuses on finding the different effects of different combinations of autonomous vehicle penetration and Passenger Car Units (PCU) on the chosen road traffic model. Four parameters are studied: traveled daily kilometers, daily hours, total daily delay and average network speed. The analysis improves the four parameters differently by implementing autonomous vehicles. The parameter total delay has the most significant reduction. Finally, several mathematical models are developed for the percentage of improvement for each chosen parameter.

Legislative aspects of interaction between the state and religious organizations
Authors: Savushkin S.
Published: April 2021

In this paper we write about the relationship of religious and moral traditions and the state regulatory apparatus. The significant place of religion in the Constitution and legislative acts of Russia and other countries is emphasized. The work deals with some aspects of the Federal law "On freedom of conscience and religion" and the danger of missionary expansion from the outside. Religion is not only a part of the spiritual life of the country, a source of ethical norms, but also a serious political factor. Through non-cultural religious groups, the country may weaken and lose its state sovereignty. In Russia, statehood was formed on the basis of the traditions of the Orthodox Church, so the opportunities in the development of the Russian state largely depend on its well-being. Qualitative and balanced stateconfessional relations are the basis of Russia's spiritual security.

Authors:   , Lemos Bárbara Torisu
Published: April 2021

Este trabalho analisa a construção da identidade da mulher e a representação de gênero na telenovela Orgulho e Paixão, que foi exibida pela Rede Globo em 2018, no horário das 18h. Por meio do entendimento dos valores sociais atribuído às mulheres do século XX, buscamos compreender como as personagens da trama atuavam para tensionar com esses valores tradicionais que destinavam as mulheres ao espaço do lar e, principalmente, ao casamento e quais atitudes e pensamentos seriam abordados para a criação da identidade da mulher moderna. A metodologia escolhida foi a Análise da Materialidade Audiovisual, que é desenvolvida pelo Núcleo de Jornalismo e Audiovisual (UFJF-CNPq), pela qual buscamos entender a unidade entre texto + som + imagem + texto + edição. A partir desta análise quali-quantitativa, verificamos que as personagens e as situações de concordância e de discordância nos discursos sobre os valores da mulher contribuíram para colocar em evidência o principal debate, que era a posição da mulher dentro da sociedade. Identificamos que, como Orgulho e Paixão é uma telenovela de época, esses valores tradicionais são muito fortes na sociedade e os tensionamento propostos pelas personagens femininas ficaram mais evidentes.

The process for the production of biogas begins in the collection of organic waste, the career of Renewable Energies of the UTSOE, creates a prototype of biodigester. In order to level the ratio of organic matter and water, within the biodigestion process it is necessary to crush the organic waste, to facilitate its decomposition, once the reactor is filled, it is hermetically sealed to obtain biogas. As a complement to the biodigester prototype, a desktop application was developed to speed up the biodigester calculations, facilitating the obtaining of data referring to the approximate amounts of methane gas produced by a specific amount of organic matter with its properties. Developing: The project is developed in two phases: 1.- Investigate and characterize the organic waste generated in the UTSOE, for the filling of a biodigester, with the purpose of producing biogas from the laboratory. 2.- Develop a desktop application that streamlines and simplifies the methane gas calculation process that occurs when mixing some organic materials and their properties, and thus define whether the proposed mixture is productive or not. The results obtained represent the basis for new research on bioenergy in the area, by proposing a model that allows studies and tests, whose process is agile to have a software to perform the required calculations.

Ушбу мақолада ўзбек халқ оғзаки ижодига мансуб достонлардаги от образи ва от билан боғлиқ муҳим детал — қанот ҳақида сўз юритилади. Қанот деталининг эпик асардаги ўрни ва аҳамияти қай даражада муҳим эканлиги достонлардан олинган муҳим парчалар, халқ орасида шуҳрат топган афсона ва ривоятлар ёрдамида тадқиқ қилинади. Қанотли тулпор, учар от сингари образларнинг эпик сюжетга шунчаки муболағали тасвирларни қўллаш мақсадида эмас, балки муайян мақсадни кўзлаб киритилиши, кўп ўринларда уларнинг халқ мифик тасаввурлари билан чамбарчас боғлиқлиги, қанот детали олиб ташланган ўринларда эпик асар мазмуни ва бадииятига футур етиши мумкинлиги далиллар ёрдамида очиб берилади. Муаллиф ўз фикрларни далиллашда, асосан, Алпомиш эпосидаги Бойчиборнинг пойгада қанот чиқариб учиш ҳолатига эътибор қаратиб, жиддий таҳлиллардан сўнг илмий хулосаларга келади. Достонларда тасвирланган қаҳрамоннинг отини исталган ўринда қанотсиз тасаввур қилиб бўлмаслиги, отдаги бу қанотнинг ва умуман, бу каби мифик белгиларнинг истифода этилиши бежиз эмаслиги, ушбу белгилар достон учун муҳим детал бўлиб хизмат қилиши ҳақидаги фикрлар асосланиб, умумлаштирилади.
