The Evolution of Azerbaijani Dance in the Study of Afag Husseinova: A Practical Guide for a Quick Immersion in the Subject
Authors: Shahmuradova Nigar 
Published: December 2024

This article analyses Afag Husseinova’s book “The Evolution of Azerbaijani Dance,” which represents a substantial contribution to the field of study. The research encompasses the origins, historical evolution, and contemporary practices of Azerbaijani dance art. Assessing the impact of this work on the choreology of Azerbaijan necessitated not only a content analysis of the book but also an examination of the context, including a review of scholarly sources on this and related topics accessible to contemporary researchers. An expeditious examination of the historiography of Azerbaijani dance disclosed a lack of comprehensive research in this domain, thereby highlighting the significance of A. Husseinova’s contributions.The book delineates the history of Azerbaijani dance into three distinct periods: prehistoric, mediaeval, and modern. The analytical sources comprise petroglyphs, medieval manuscripts, miniatures, and contemporary ethnochoreological data. The author delineates the relationship between traditional dance forms and contemporary Azerbaijani ballet. A. Husseinova meticulously analyses the origins of Azerbaijani dance, encompassing folklore traditions, mugham, the art of ashugs, and the impact of Russian and Western ballet schools. She examines the progression of the yalli circle dance from the Paleolithic Gobustan petroglyphs to contemporary ballet performances. Special emphasis is placed on the impact of medieval miniatures as a source for understanding the evolution of dance traditions. The study categorizes folk dances and emphasizes their ritualistic, matrimonial, quotidian, and additional roles. The primary benefit of the book is its linguistic accessibility and concise presentation, enabling rapid immersion in the subject matter. Critical comments and suggestions include the lack of appendices containing a glossary of terms, a bibliography of Azerbaijani dance, and a list of the most significant figures. Furthermore, should the author intend to produce an expanded edition, the book could be supplemented with multimedia materials under contemporary circumstances. A. Husseinova’s book makes a substantial contribution to Azerbaijani choreology by revealing the principal facets of country’s choreography and dance art. The publication will serve as a pedagogical resource for student choreographers and musicians, as well as for scholars engaged in cross-cultural and interdisciplinary research. It facilitates the dissemination and comprehensive examination of Azerbaijani dance as a distinctive phenomenon within global art.

Published: December 2024

Introdução: Doenças periodontais e sistêmicas agindo concomitantemente podem possuir inter-relações que se acham baseadas nos fundamentos da Medicina Periodontal. Doenças periodontais compreendem patologias infecciosas imunoinflamatórias que podem afligir o trato respiratório ocasionando processos infecciosos. A asma consta de patologia inflamatória crônica que aflige as vias aéreas. Objetivo: O objetivo do presente artigo foi averiguar como pode ocorrer inter-relacionamento e evidência de manifestações clínicas entre a doença sistêmica, asma e as doenças periodontais. Metodologia: Realizou-se revisão narrativa da literatura com busca nas bases de dados LILACS, Google Acadêmico e levantamento de estudos e artigos que tratavam sobre a possível relação existente entre a doença sistêmica, asma e as doenças periodontais. Resultados: Realizou-se leitura seletiva e analítica de todos os artigos levantados e constatou-se na maioria dos estudos que a possível interação existente entre asma e doenças periodontais pode ser oriunda da patogênese manifestada concomitantemente pelas duas patologias, asma e doenças periodontais ocorrendo conjuntamente. A administração de fármacos também pode ocasionar repercussões com evidência de inter-relacionamento entre doenças periodontais e asma. Em âmbito odontológico, em decorrência da asma pode haver manifestações de xerostomia e de hipossalivação. Conclusão: Concluiu-se que a abordagem odontológica e diagnóstica executada de maneira correta em indivíduos portadores de asma pode agir preventivamente, minimizando a ocorrência de complicações sistêmicas que poderiam advir da realização de procedimentos odontológicos, concomitantemente possibilitando que esses pacientes possuam uma melhor qualidade de vida, reduzindo-se o desconforto proveniente da realização de tratamentos dentários curativos e mais complexos.

El auge de las Tic ha permitido que el sistema educativo goce de la presencia de estas en el aula para apoyo en el aprendizaje, esto ha generado que los jóvenes se vean inmersos en el lenguaje que los memes les permiten entender. De hecho, el término “meme” tiene su origen en la teoría de Dawkins (1976), quien lo sitúa como la unidad de transmisión cultural por imitación, así que la información cultural se transmite de cerebro a cerebro en unidades consideradas como simples (un concepto, una técnica, una costumbre, entre otros) y van conformando sistemas más complejos. Estas unidades, que el autor llama memes, son también replicadores a través de los cuales la cultura evoluciona. Entonces, ¿Cómo podemos relacionar los memes con la enseñanza del lenguaje, las ciencias naturales y las ciencias sociales en nuestra cultura? Pues bien, esta investigación se centra en el uso del meme como estrategia educativa y comunicativa para el desarrollo del aprendizaje significativo en las asignaturas de Lengua Castellana, Ciencias Naturales y Ciencias Sociales en estudiantes de ciclo V de una IED ubicada al sur de Bogotá. Para esto, se retoman autores como Heylighen (1976), Arango (2015) y Alzate (2018) entre otros autores del plano del Lenguaje; Castells, (2014), a su vez para el panorama de las ciencias naturales se indaga en autores como Chicaiza & Bastardo (2022). Todo esto con el fin de dar como resultado creaciones propias de memes que ahonden en el proceso y la praxis científica.

Published: December 2024

The objective of this research work is to analyze the unavailability of the population of the State of Hidalgo for access to information technologies through the generation of the index of material unavailability of ICT, which allowed the classification of the municipalities in five dimensions analyzed statistically and using georeferencing techniques. The variables selected for this purpose were Internet connectivity, use of fixed telephone, mobile telephone, and computer. The information used was taken from the 2020 Population and Housing Census, as it was the only source of information that met the required Municipal coverage.
Among the most significant findings, we found a clear tendency to use cell phones for connectivity instead of using the Internet on computer equipment; however, this brings with it the difficulty for efficient use in activities such as school homework.

AbstractObjectiveLittle is known about the disease progression of Parkinson's disease patients with subjective cognitive complaint (PD‐SCC). This longitudinal cohort study aims to compare the progression of clinical features and quality of life (QoL) in PD patients with normal cognition (NC), SCC, and mild cognitive impairment (MCI).MethodsA total of 383 PD patients were enrolled, including 189 PD‐NC patients, 59 PD‐SCC patients, and 135 PD‐MCI patients, with 1–7 years of follow‐up. Linear mixed models were applied to evaluate longitudinal changes in motor symptoms, nonmotor features (cognitive impairment, depression, and excessive daytime sleepiness), and QoL in PD.ResultsAt baseline, PD‐SCC patients had lower Beck Depression Inventory (BDI) scores and Parkinson's Disease Questionnaire‐39 (PDQ‐39) scores than PD‐NC patients (all p < 0.05). Longitudinal analyses revealed that the PD‐SCC group exhibited faster progression in terms of BDI scores (p = 0.042) and PDQ‐39 scores (p = 0.035) than the PD‐NC group. The PD‐MCI group exhibited faster progression rates in the Epworth Sleepiness Scale scores (p = 0.001) and PDQ‐39 scores (p = 0.005) than the PD‐NC group. In addition, the PD‐SCC group exhibited a greater reduction in attention (Trail Making Test Part A, p = 0.047) and executive function (Stroop Color‐Word Test, p = 0.037) than the PD‐NC group.InterpretationPD‐SCC patients exhibited faster deterioration of depression and QoL than PD‐NC patients, and SCC may be an indicator of initial attention and executive function decline in PD. Our findings provided a more accurate prognosis in PD‐SCC patients.

Published: October 2021

AbstractCopper‐catalyzed routes have been achieved for the synthesis of 3‐nitroquinolines from readily available nitroolefins and anthranils. This reaction proceeds via the [4+2] cycloaddition between anthranils and nitro‐styrenes under mild reaction conditions to obtain biologically important heterocycles. A wide range of diversely substituted nitro‐olefins and anthranils are successfully employed in this reaction to access a series of 3‐nitro‐quinolines in 81–93% yields. The synthetic utility of the present methodology is also illustrated in this manuscript.magnified image

Recent Total Syntheses of Cephalotaxine‐Type Alkaloids (2016–2021)
Authors: Jeon Hongjun 
Published: October 2021

AbstractOver the past decades, scientists have obtained a diverse range of interesting natural products, including alkaloids, terpenoids, and flavonoids from the genus Cephalotaxus. Among them, cephalotaxine‐type alkaloids have attracted considerable attention from chemists because of their intriguing pentacyclic structures as well as the diversity of naturally occurring analogs. Notably, homoharringtonine (Trade name: Synribo®) is a pharmaceutical drug, which was approved by the FDA in 2012 for the treatment of chronic myeloid leukemia, implying that cephalotaxine‐type alkaloids have medicinal value. Since the first total synthesis of cephalotaxine, almost 70 total syntheses of cephalotaxine‐type alkaloids have been reported, involving various synthetic methodologies. Because of their potential as molecular platforms for the development of organic chemistry, the total synthesis of cephalotaxine‐type alkaloids has been extensively studied. This review focuses on the recent 10 total syntheses of cephalotaxine‐type alkaloids reported in the period, 2016–2021. In addition, synthetic hallmarks, such as common synthetic routes and ring‐opening features of this class, were also addressed.

Published: October 2021

AbstractThe active site of [FeFe]‐hydrogenase (H2ase) is preorganized with an amine (azadithiolate) as a proton relay and a [4Fe4S] subunit as an electron reservoir, which together lower the overpotential for proton reduction and hydrogen oxidation by multiple‐site concerted proton–electron transfer (MS‐CPET). Herein, we report a mononuclear manganese complex,fac‐[Mn(CO)3(6‐(2‐hydroxyphenol)‐2‐pyridine‐2‐quinoline) Br] (1), as a rare model to fully mimic the functions of the H2ase. In1, a redox‐active bidentate ligand with a pendent phenol replicates the roles of the electron reservoir and the proton relay in the enzyme. Experimental and theoretical studies revealed two consecutive MS‐CPET processes in the catalytic cycle, in each of which an electron stored in the reductive ligand and a proton at the proximal phenol moiety are transferred to the Mn center in a concerted way. By virtue of this mechanism, complex1exhibited a low overpotential comparable to that of natural enzyme in electrochemical hydrogen production using phenol as a proton source.
Rhodium‐Catalyzed Asymmetric Hydrogenation of 3‐Benzoylaminocoumarins for the Synthesis of Chiral 3‐Amino Dihydrocoumarins
Authors: Xu Yunnan , Liu Delong , Deng Yu , Zhou Yi , Zhang Wanbin 
Published: October 2021

AbstractAn asymmetric hydrogenation of 3‐benzoylaminocoumarins was achieved for the first time using our BridgePhos‐Rh catalytic system, providing chiral 3‐amino dihydrocoumarins in high yields (up to 98 %) and with excellent enantioselectivities (up to 99.7 %ee). The relationship between the enantioselectivities of the hydrogenations and the dihedral angles and the resulting π‐π stacking effects of the BridgePhos‐Rh complexes, which were determined by X‐ray diffraction analysis, are discussed. The corresponding hydrogenated products allow for many transformations, providing several chiral skeletons with important physiological and pharmacological activities.
Acceptorless Dehydrogenation of Methanol to Carbon Monoxide and Hydrogen using Molecular Catalysts
Authors: Kaithal Akash , Chatterjee Basujit , Werlé Christophe , Leitner Walter 
Published: October 2021

AbstractThe acceptorless dehydrogenation of methanol to carbon monoxide and hydrogen was investigated using homogeneous molecular complexes. Complexes of ruthenium and manganese comprising the MACHO ligand framework showed promising activities for this reaction. The molecular ruthenium complex [RuH(CO)(BH4)(HN(C2H4PPh2)2)] (Ru‐MACHO‐BH) achieved up to 3150 turnovers for carbon monoxide and 9230 turnovers for hydrogen formation at 150 °C reaching pressures up to 12 bar when the decomposition was carried out in a closed vessel. Control experiments affirmed that the metal complex mediates the initial fast dehydrogenation of methanol to formaldehyde and methyl formate followed by subsequent slow decarbonylation. Depending on the catalyst and reaction conditions, the CO/H2 ratio in the gas mixture thus varies over a broad range from almost pure hydrogen to the stoichiometric limit of 1:2.
Dual‐Ion Intercalation and High Volumetric Capacitance in a Two‐Dimensional Non‐Porous Coordination Polymer
Authors: Banda Harish , Dou Jin‐Hu , Chen Tianyang , Zhang Yugang , Dincă Mircea 
Published: October 2021

AbstractIntercalation is a promising ion‐sorption mechanism for enhancing the energy density of electrochemical capacitors (ECs) because it offers enhanced access to the electrochemical surface area. It requires a rapid transport of ions in and out of a host material, and it must occur without phase transformations. Materials that fulfil these requirements are rare; those that do intercalate almost exclusively cations. Herein, we show that Ni3(benzenehexathiol) (Ni3BHT), a non‐porous two‐dimensional (2D) layered coordination polymer (CP), intercalates both cations and anions with a variety of charges. Whereas cation intercalation is pseudocapacitive, anions intercalate in a purely capacitive fashion. The excellent EC performance of Ni3BHT provides a general basis for investigating similar dual‐ion intercalation mechanisms in the large family of non‐porous 2D CPs.
Can morphotaxa be assessed with photographs? Estimating the accuracy of two‐dimensional cranial geometric morphometrics for the study of threatened populations of African monkeys
Authors: Cardini Andrea , de Jong Yvonne A. , Butynski Thomas M. 
Published: October 2021

AbstractThe classification of most mammalian orders and families is under debate and the number of species is likely greater than currently recognized. Improving taxonomic knowledge is crucial, as biodiversity is in rapid decline. Morphology is a source of taxonomic knowledge, and geometric morphometrics applied to two dimensional (2D) photographs of anatomical structures is commonly employed for quantifying differences within and among lineages. Photographs are informative, easy to obtain, and low cost. 2D analyses, however, introduce a large source of measurement error when applied to crania and other highly three dimensional (3D) structures. To explore the potential of 2D analyses for assessing taxonomic diversity, we use patas monkeys (Erythrocebus), a genus of large, semi‐terrestrial, African guenons, as a case study. By applying a range of tests to compare ventral views of adult crania measured both in 2D and 3D, we show that, despite inaccuracies accounting for up to one‐fourth of individual shape differences, results in 2D almost perfectly mirror those in 3D. This apparent paradox might be explained by the small strength of covariation in the component of shape variance related to measurement error. A rigorous standardization of photographic settings and the choice of almost coplanar landmarks are likely to further improve the correspondence of 2D to 3D shapes. 2D geometric morphometrics is, thus, appropriate for taxonomic comparisons of patas ventral crania. Although it is too early to generalize, our results corroborate similar findings from previous research in mammals, and suggest that 2D shape analyses are an effective heuristic tool for morphological investigation of small differences.
