Authors: Светлов Роман Викторович , Протопопова Ирина Александровна
Published: September 2024

В статье предлагается обзор изучения наследия Платона в отечественной культуре и науке. Анализируется известная концепция о платоно-византийских корнях русской интеллектуальной и духовной культуры; подчеркивается значение «открытия Платона» в России в xviii-xix столетиях. Рассматриваются судьбы исследований платоновского наследия и оценок философии Платона в советское время. Основное внимание в статье уделяется современному состоянию изучения «платоновского вопроса». Проанализированы основные подходы и тенденции, начавшие формирование еще в 1980-х, а также новые веяния, особенно характерные для 2010-х. Описана история институализации этих исследований в нашей стране в научно-академическом, образовательном, издательском и общественном контекстах. Показано, как в отечественной науке оцениваются и используются традиционный анализ учения Платона («эволюционный подход»), какую роль сыграли тюбингенская оценка «неписаной философии» и аналитический подход к платоновским текстам. Особое внимание уделено формированию в отечественной науке институционального подхода», а также расширению влияния «драматического» прочтения платоновских текстов, в частности - в контексте не только метафизики, но и философии политики, философии математики.

The article offers an overview of the studies dedicated to Plato’s legacy in Russian culture and humanities. The well-known concept of Platonico-Byzantine roots of Russian intellectual and spiritual culture is analyzed. Attention is paid tothe ‘discovery of Plato’ in Russia in the xviii-xix centuries, and the history of translations of Platonic corpus into Russian. The authors also review the vicissitudes ofstudies of Plato’s legacy and assessments of Plato’s philosophy in the Soviet period. But primarily, the article focuses on the current state of the ‘Platonic question’. Themain approaches and trends which started emerging in the 1980s, as well as new ones,especially characteristic of the 2010s, are analyzed. The article describes the history of institutionalization of these studies in Russia in academic, educational, publishing,and social contexts. It is shown how the traditional analysis of Plato’s teaching (the so-called ‘development approach’) is evaluated and used in Russian humanities, and what role the Tübingen assessment of Plato’s ‘unwritten philosophy’ has played. The authors mention the growing influence of the ‘analytical approach’ to Platonic textsand outline the specifics of the ‘analytical history of philosophy’ in Russia. Specialattention is paid to the formation in Russian humanities of the ‘institutional approach’ and to the expanding influence of the ‘dramatic’ reading of Plato’s texts - not only in the context of metaphysics but also in connection with the philosophy of politics, the philosophy of mathematics.
The “Self Selfness” as a Methodological and Linguistic Principle of Alexei Losev’s Philosophy
Authors: Гравин Артём Андреевич
Published: September 2024

В статье рассматривается «са́мое само́» («самость») как языковой и методологический принцип философии всеединства Алексея Лосева. Склонность к универсализму обусловливала отношение Лосева к всеединству как наиболее логически последовательной философской позиции, подразумевающей объединяющий принцип и объединяемую им цельную систему знания. В ряде своих ранних работ Лосев имплицитно и логически выводит принцип онтологической неявленности и языковой невыразимости одного (единого), не анализируя подробно и не именуя его в виде какой-либо определенной категории. Этот принцип получил свое наименование «са́мое само́» в одноименной работе. Са́мое само́, по Лосеву, предполагает неявленное и явленное измерение и в то же время полагается допредикативной, внекатегориальной и внеонтологической «категорией». Исходя из этого, фактическое мышление самости вне субъективного и объективного бытия (что в синтезе для Лосева означает бытие личности) определяет характер самого этого мышления в его целостности и, как следствие, характер основанного на нем философского дискурса. При гипотетическом расширении содержания термина «са́мое само́» представляется возможным провести его структурные аналогии с категорией «ипостась» в богословско-персоналистическом значении.

This article examines the “self selfness” as a linguistic and methodological principle of Alexei Losev’s philosophy of all-unity. The inclination to universalism determined Losev’s attitude to all-unity as the most logically consistent philosophical position, implying a uniting principle and an integral system of knowledge that it unites. In some of his early works, Losev implicitly and logically deduces the principle of ontological indistinctness and linguistic inexpressibility of the One, without analyzing in detail and without naming it in the form of any definite category. This principle got its designation as the “self selfness” in the work of the same name. The “self selfness”, according to Losev, presupposes an apophatic and cataphatic dimension and, at the same time, it is assumed to be a pre-predicative, out-of-category and out-of-ontology “category”. Therefore, the actual thinking of the self outside of subjective and objective being (which in synthesis means the being of the person for Losev) determines the nature of this very thinking in its integrity and, as a consequence, the nature of the philosophical discourse based on it. With a hypothetical expansion of the content of the term “self selfness”, it is possible to draw its structural analogies with the category of “hypostasis” in the theological-personalistic sense.
ARistotle. On Sleep and WaKing (A TRanslation and Notes)
Authors: Месяц Светлана Викторовна
Published: September 2024

Трактат Аристотеля О сне и бодрствовании () входит в число малых психологических сочинений философа, традиционно объединяемых в сборник под названием . Основную тему трактата составляет поиск развернутого определения сна, включающего в себя указание на формальную, материальную, целевую и действующую причины этого состояния. Аристотель спрашивает, что такое сон, каково его назначение, состоянием какой части тела и души он является и какие причины отвечают за его возникновение. Проведенное исследование позволяет философу установить, что сон представляет собой временное прекращение ощущения, вызванное неспособностью главного органа чувств осуществлять естественную для него деятельность; что причиной сна является периодическое вытеснение тепла из верхней части тела в малую область сердца под давлением стекающих вниз тяжелых и влажных испарений; а целью и назначением - отдых, без которого животное не могло бы продолжать бодрствовать. Предлагаемый читателю первый перевод трактата на русский язык снабжен подробными комментариями, в которых анализируется ход рассуждения Аристотеля, раскрывается содержание основных понятий его учения о душе и обсуждаются отдельные сложные места этого сочинения.

Aristotle’s treatise () belongs to the series of short psychological works of the philosopher traditionally grouped together under the title . Considering sleep as one of the most important vital functions in which both soul and body share, Aristotle seeks a definition of sleep that would indicate not only its essential form and goal, but also its material and efficient causes. In order to define sleep in terms of his theory of four causes, Aristotle considers what it is, what its purpose is, in which part of the body and soul it takes place, and what agent brings it about. In the course of the study it becomes clear that sleep consists in a temporary inactivity of senses caused by the incapacity of the primary sense-organ to carry out its natural activity. The inability of this organ is in its turn due to the periodic displacement of the natural heat from the upper part of the body into the small region of the heart under the pressure of heavy and moist vapors flowing down. And the final cause of sleep is to give rest to the senses so that the animal can stay awake. This publication of the first Russian translation of Aristotle’s treatise is provided with detailed commentary, which analyzes the course of Aristotle’s argument, explains basic concepts of his doctrine of the soul and discusses the most challenging passages.
The Metamorphosis Goliae Episcopi (Text, Translation, and Notes)
Authors: Гараджа Алексей Викторович
Published: September 2024

В публикации представлены текст и комментированный русский перевод «голиардской» поэмы xii века «Метаморфоза епископа Голиафа», приписываемой перу Уолтера Мапа (1130 – ок. 1210), придворного английского короля Генриха II, но в действительности написанной кем-то из учеников либо последователей Петра Абеляра (ок. 1079 – 1142) вскоре после осуждения философа на соборе в Сансе (1141) под давлением Бернарда Клервосского (1090–1153). Первая половина xii века ознаменована возрождением интереса к платоновской философии и к академическим — университетским — формам организации научной деятельности. Вместе с тем это время проведения Григорианских реформ в католической церкви, важным моментом которых было насаждение целибата среди священнослужителей, закрепленного Вторым Латеранским собором (1139). Но именно клирики занимались наукой и преподаванием в школах, создававшихся при культовых центрах. Отсюда коллизия между ученостью и любовью — полноценной и полнокровной, за которую Абеляр был наказан особенно жестоко. Автор поэмы старается показать, что любовь и ученость должны не противопоставляться и разлучаться, а подпитывать и дополнять друг друга. Естественным образцом берется при этом «Бракосочетание Филологии и Меркурия» Марциана Капеллы (fl. ок. 410–420). «Метаморфоза» подразумевает, по-видимому, осуществление именно такого проекта сочетания любви и науки в пику церковному мракобесию. Перевод выполнен по изданию Уинтропа Уэзерби (2017).

The publication presents the text and a commented Russian translation of the xii-century Goliardic poem , wrongly attributed to Walter Mapes (1130 – ок. 1210), a courtier of King Henry II of England, but in reality written by a student or champion of Peter Abelard (c. 1079 – 1142) soon after the philosopher’s condemnation at the Council of Sens (1141) executed under the pressure of Bernard of Clairvaux (1090–1153). The first half of the xii century is marked by the renascent interest for the Platonic philosophy, and for academic or “universitarian” forms of organization of scholarly activities. At the same time, it was the epoch of Gregorian reforms within the Catholic Church, including, as an important point, the imposition of celibacy among the clergy, which had been prescribed by the Second Lateran Council (1139). But it was precisely the clerics who learned and taught at the schools that were created at various ecclectical centers, cathedrals and abbeys. Hence a collision between learning and love, a full-fledged and full-blown love, for which Abelard had been punished with an especial cruelty. The author of the poem attempts to show that love and learning are not to be opposed and separated, but on the contrary, are supposed to nourish and complement each other. The obvious model is supplied by by Martianus Capella (fl. c. 410–420). The “metamorphosis” apparently intends an implementation of such a purported mating of love and scholarship against ecclesiastical monastic obscurantism. The translation is based on Winthrop Wetherbee’s edition of the text (2017).
ANALYSIS OF WATER AVAILABILITY OF MADI IRRIGATION NETWORK
Authors: Pradanapa Permada Garah , Soeryamassoeka S. B. , Yulianto Eko
Published: September 2024

This research analyzes the water availability of the Madi Irrigation Network through detailed assessments of evapotranspiration and discharge data from 2008 to 2019. The study reveals significant seasonal and inter-annual variations in evapotranspiration rates, which typically increase during warmer months and decrease in cooler periods. This fluctuation is closely linked to climatic conditions, influencing agricultural water demand. Monthly discharge data further illustrates these variations, showing high discharge rates in the rainy season (e.g., January and December) and lower rates during drier periods (e.g., August and September). The 80% dependable discharge rates reflect similar seasonal trends, with notable peaks and troughs correlating with rainfall patterns. These insights underscore the importance of adaptive water management strategies to optimize irrigation practices, manage water resources effectively, and address the impacts of climate variability. By understanding these patterns, water managers can better plan for periods of surplus and scarcity, enhancing agricultural productivity and sustainability.

Published: September 2024

The investigation of inhomogeneous surfaces, where various local structures co-exist, is crucial for understanding interfaces of technological interest, yet it presents significant challenges. Here, we study the atomic configurations of the (2 × m) Ti-rich surfaces at (110)-oriented SrTiO3 by bringing together scanning tunneling microscopy and transferable neural-network force fields combined with evolutionary exploration. We leverage an active learning methodology to iteratively extend the training data as needed for different configurations. Training on only small well-known reconstructions, we are able to extrapolate to the complicated and diverse overlayers encountered in different regions of the heterogeneous SrTiO3(110)-(2×m) surface. Our machine-learning-backed approach generates several new candidate structures, in good agreement with experiment and verified using density functional theory. The approach could be extended to other complex metal oxides featuring large coexisting surface reconstructions.
Electro-Inductive Effects Are Additive
Authors: Westphäling Johannes , Lee Hanna , Baik Mu-Hyun
Published: September 2024

The electro-inductive effect has recently emerged as a potential alternative to traditional functional groups for modulating the chemical properties of molecules. By covalently attaching a reactive molecule to an electrode surface and applying positive or negative voltage, electrons can be withdrawn from or injected into the immobilized molecule, mimicking the inductive effect of electron-withdrawing or electron-donating functional groups. To explore whether the magnitude of the electro-inductive effect changes when molecules are attached to the electrode via multiple linkers or at different molecular positions, four derivatives of mercaptobenzonitrile—3,4-dimercaptobenzonitrile, 4- mercaptobenzonitrile, 3,5-dimercaptobenzonitrile, and 3-mercaptobenzonitrile—were self-assembled into monolayers on a gold electrode surface. The electro-inductive effect was quantified by measuring the vibrational stretching frequencies of the nitrile group using surface-enhanced Raman spectroscopy. Our findings suggest that the electro-inductive effect exhibits additive and positional characteristics similar to those of conventional functional groups. The para position is significantly more effective than the meta position, and linking the molecule to the electrode through two anchors is more effective than using a single anchor.

Authors: Handke Maria , Beierlein Frank , Imhof Petra , Schiedel Matthias , Hammann Simon
Published: September 2024

Lipids are major constituents of food but are also highly relevant substructures of drugs and are increasingly applied for the development of lipid-based drug delivery systems. Lipids are prone to oxidative degradation, thus affecting the quality of food or medicines. Therefore, analytical methods or tools that enable to assess the degree of lipid oxidation are of utmost importance to guarantee food and drug safety. Herein, we report the design, synthesis, and application of the first-in-class fluorogenic triacylglycerols that enable a dynamic monitoring of lipid oxidation via straightforward fluorescence readout. Our fluorogenic triacylglycerols can be used both in an aqueous and lipid-based environment. Further, we showed that the sensitivity of our fluorescent tracers towards oxidation can be tuned by incorporating either saturated or unsaturated acyl chains in their triacylglycerol core structure. With this, we provide a first proof-of-principle for the applicability of fluorescently labelled triacylglycerols as tracers to monitor the dynamics of lipid oxidation, thus paving the way for novel discoveries in the area of lipid analytics.

Published: September 2024

Carba-sugars – carbohydrate mimics in which the ring oxygen is replaced by a methylene group – are carbohydrate analogs of natural or synthetic origin that can have important biological functions. Especially, carba-aminosugars and glycosides containing carba-aminosugars are potent antibiotics. Furthermore, they have been shown to induce the self-cleavage reaction of the glmS riboswitch and thereby inhibit the ability of bacteria to synthesize glucosamine-6-phosphate, which is required to build up the bacterial cell wall. We report the synthesis of a library of 20 carba-glucosamine derivatives with various substituents at the carba-position including amines, alkyl, alkoxy, and aryloxy derivatives, fluorine derivatives, glycosylated derivatives and a cyclopropane derivative. The compounds were obtained in an efficient way starting from late-stage synthetic intermediates of an earlier developed synthesis of carba-substituted carba-glucosamines. All carba-glucosamine mimics were tested for their antibacterial properties against Bacillus subtilis and some of them displayed promising activities in a filter disc assay.
Exploring Flavone Reactivity: A Quantum Mechanical Study and TDDFT Benchmark on UV-Vis Spectroscopy
Authors: BHATIA MANJEET
Published: September 2024

Flavones exhibit a range of pharmacological and diverse biological activities, making them valuable candidates for drug development and complementary medicine. In this study, inclusive investigations of the chemical reactivity, kinetic stability, and biological activity of the flavone molecule are performed using B3LYP/6-311++G(d, p) density functional theory (DFT). The proton affinity (PA), ionisation energy (IE), and electron affinity (EA) along with global reactivity parameters such as chemical potential (µ), chemical hardness (η), softness (σ), electrophilic index (ω), and electronegativity (χ) of flavone molecule are computed. A comparative study with different DFT/correlation functional such as wB97XD, M062X, and MP2 shows that the adopted DFT method is reliable and computationally economical. Benchmark calculations using B3LYP, CAM- B3LYP, PBE0, M06-2X, LC-wHPBE, and wB97XD on the excited electronic states and absorption spectra indicate that CAM-B3LYP, M06-2X, and wB97XD are the most effective for predicting the absorption spectra of Flavone.
Development and Comparison of 3D Seismic Geology and Shear-wave Velocity Models of Metro Vancouver
Authors: Adhikari Sujan , Molnar Sheri
Published: September 2024

This study presents a 3D regional modeling of seismic geology and shear wave velocity (Vs) in Metro Vancouver for seismic microzonation and hazard prediction. Leveraging an extensive geodatabase compiled from invasive and non-invasive in situ data, including lithological logs and seismic field data, we delineated four major geological units: Holocene post-glacial and Pleistocene inter/glacial sediments, and Tertiary sedimentary and Pre-Tertiary Coast Mountain plutonic rocks.
Seismic geology model integrates the four primary geological formations, leveraging significant impedance-based surfaces derived from meticulously analyzed borehole stratigraphic logs and Vs depth profiles sourced from 2333 georecords, enhancing its depth and accuracy. Through a meticulous comparison with established interpreted geological cross-sections, we have reaffirmed the robustness and reliability of our seismic geology modeling approach. A numerical 3D “geotechnical layer” Vs model with 11 isovelocity surfaces was developed using 688 Vs depth profiles. Comparison with microtremor amplification spectra confirms our 3D models' reliable use in predicting site amplification. We find that the combination of local geology (thicknesses) and Vs information outperforms prediction in fundamental peak frequency compared to using only local geology combined with regional Vs information. Our study contributes to advancing understanding of seismic hazards in Metro Vancouver, highlighting the importance of incorporating localized seismic site conditions for precise regional seismic hazard assessments.

A análise dos parâmetros morfométricos pelo emprego de técnicas de Processamento Digital de Imagens (PDI) e Sistema de Informação Geográfica (SIG) constitui um instrumento adequado para análise ambiental, pois fornece uma visão integrada da paisagem dentro de um ambiente computacional. A compartimentação geomorfológica neste ambiente auxilia o diagnóstico ambiental e estudos para a realocação das atividades humanas. Neste contexto, o presente estudo tem por objetivo fazer uma compartimentação geomorfológica na bacia do rio Corrente/BA, definindo critérios de utilização da área conforme a dinâmica natural. Inicialmente confeccionou-se o Modelo Digital de Terreno (MDT) da bacia do rio Corrente a partir de 23 cartas topográficas (1:100 000) em formato digital. As cartas foram interpoladas pelo método TOPOGRID do programa ArcInfo. A partir do MDT foram gerados os mapas morfométricos de declividade, direção de fluxo e área de contribuição da bacia. Os mapas foram contrapostos a partir da análise de gráficos de dispersão e emprego de técnicas de processamento digital de imagens (composições coloridas e manipulação de contraste). Isto possibilitou a definição de padrões geomorfológicos distintos, que podem auxiliar a formulação de prognósticos para a definição de diretrizes para o uso do solo.

Published: September 2024

O trabalho foi desenvolvido em vasos, em casa-de-vegetação, para avaliar o efeito residual da adubação potássica com rochas moídas sobre o desenvolvimento vegetativo e o acúmulo de potássio (K) por plantas de soja em Latossolo Vermelho distroférrico (LVdf) e Neossolo Quartzarênico (NQ), anteriormente cultivados com girassol. As rochas fontes de potássio, arenito vulcânico, brecha alcalina, carbonatito, biotita xisto e ultramáfica alcalina, além da fonte padrão de K, cloreto de potássio, foram aplicadas nas quantidades de 0, 150 e 300 mg kg-1 de K2 O por ocasião da semeadura do girassol. Avaliou-se a produção de matéria seca da parte aérea das plantas colhidas no florescimento pleno, além das concentrações e o acúmulo de K nos tecidos. Também avaliou-se, ao final do cultivo, o K disponível no solo pelo extrator Mehlich-1. Tanto a produção quanto o acúmulo de K foram influenciados pelas fontes de potássio utilizadas. As rochas ultramáfica alcalina e biotita xisto apresentaram as maiores eficiências agronômicas residuais para a produção de matéria seca e como fonte de liberação lenta de K. O carbonatito apresentou viabilidade de utilização como fonte de K, porém com solubilidade mais lenta que a ultramáfica alcalina e a biotita xisto. O arenito vulcânico não apresentou viabilidade agronômica como fonte de K. O extrator Mehlich-1 não se mostrou adequado para avaliar a disponibilidade de K em solos adubados com a brecha alcalina.

Published: September 2024

A Savana brasileira, conhecida como Cerrado, é o principal tipo de vegetação no Brasil Central, cobrindo aproximadamente 23% do território nacional. É formado por um mosaico de coberturas como campestres, arbustiva e florestal, e apresenta uma fenologia típica, resultante da variação pluviométrica e alta dependência geobotânica nesta região. Imagens adquiridas na mesma área em tempos diferentes representam uma valiosa fonte de informação para o monitoramento regular da superfície terrestre, permitindo descrever a evolução da cobertura da terra, fenologia da vegetação entre outros. Desta forma, o objetivo deste trabalho é identificar as assinaturas temporais do cerrado na região do Ecomuseu do Cerrado através do processamento de série temporal de imagens MODIS. A metodologia pode ser subdivida nas seguintes etapas: (a) elaboração do cubo das imagens de NDVI, onde o perfil “Z” corresponde à assinatura temporal do NDVI, (b) eliminação do ruído utilizando a transformação Mininum Noise Fraction (MNF), e (c) análise da assinatura temporal do NDVI. O estudo concluiu que o NDVI é útil na diferenciação entre os tipos de vegetação do Cerrado. A formação florestal apresentou os maiores valores de NDVI entre os perfis temporais, além da menor variação entre as estações.

Realizar um trabalho sobre a temática agrária é efetuar uma analise temporal, econômica e social, bem como relatar as reais situações de desigualdades vistas no espaço agrário nacional em especial o espaço agrário paraibano. Estas relações estão inseridas no contexto nacional, como um dos “gritos” dados pela sociedade, para mostrar ao mundo os contrastes, descriminações, explorações, e a imparcialidade com que se trata a Reforma Agrária. O objetivo deste trabalho foi analisar as condições de vida no que cerne mais especificamente as condições e relações de trabalho, renda, moradia e continuidade no espaço agrário do Assentamento Santa Helena I-Sapé/PB. Utilizou-se para fundamentação do estudo, a matriz teórica do espaço. Neste sentido o espaço é concebido como um conjunto de sistemas orientados em objetivos e ações. Na perspectiva metodológica que se consistiu de um levantamento, documental e bibliográfico, para fundamentar as propostas de estudo. Para tanto se destaca alguns autores, que contribuíram de maneira valorosa que são: Castro (1967); Lemos (1996); Moreira (1997); Pereira (2005) e Varela (2006), entre outros, como pesquisas em site do MST, INCRA e IBGE, que contribuíram para execução do trabalho. Através das idéias e temáticas destes autores, foi se construindo um conhecimento científico necessário para se elaborar o trabalho. Posteriormente foram efetuadas as visitas/pesquisas de campo que se constituíram como materialização do estudo, durante o período de janeiro 2006 a fevereiro 2007. Durante a pesquisa foram valorizadas as preocupações relacionadas com a história oral de cada um, atuando como elemento significante que contribuiu para a execução do trabalho, e fez entender que a Reforma Agrária é o primeiro passo a primeira conquista. Investir neste projeto é dá suporte social para promover a equidade entre os camponeses e corrigir o abismo existente entre as classes majoritárias e minoritárias.

Relevance. Despite the capabilities of modern medicine, Wilson’s disease remains a diagnostic challenge for many doctors. Many symptoms are often overlooked, leading to delayed diagnosis and, as a result, early disability and death of patients at a young age. The rarity of this disease and the lack of data on liver damage in this disease make the topic of our study particularly relevant. Purpose – based on a retrospective and prospective analysis of 102 patients with Wilson’s disease, we studied structural changes in the liver and evaluated the level of the most common biochemical markers of its function. Materials and methods. Based on a review of current data on the topic of our study, we analysed the literature, original articles, randomised controlled trials, meta-analyses and book chapters. We used clinical and neurological, biochemical neuroimaging and ultrasound methods of research. Results. Our study, as well as a review of the world literature, showed that all patients with Wilson’s disease, in the neurological phase of the disease, have both structural and functional liver disorders. It was found that pathological processes in the liver are most often asymptomatic and have a minimal degree of enzymatic activity, but with significantly reduced compensatory adaptive capabilities. Conclusions. Despite the fact that Wilson’s disease is a rather rare, genetically determined disease, it is common in the practice of both neurologists and general practitioners, due to liver dysfunction, therefore, early diagnosis and timely pathogenetic treatment lead to regression of symptoms and improvement of the quality and duration of life of patients.

Published: September 2024

Background. Heparin-induced thrombocytopenia (HIT) is a complication of heparin therapy caused by the body's immune response. Even though heparin therapy is performed to prevent thrombotic events, the antibodies formed in response cause platelet activation and subsequent release of thrombin, which leads to the opposite result: an increased risk of venous and/or arterial thrombosis. Purpose – is to analyze and summarize data from literary sources devoted to the study of timely diagnosis, prevention and treatment of heparin-induced thrombocytopenia. Materials and methods. Publications were selected by keywords in PubMed (https://pubmed.ncbi.nlm.nih.gov/) and Google Scholar databases (https://scholar.google.com/), published in 2017–2022. Results. The article analyzes available data from meta-analyses of conducted studies on the frequency of complications of heparin therapy, its impact on the further course of the disease, existing theories of pathogenesis, methods of diagnosis and treatment. Diagnosis of the gastrointestinal tract is difficult. Such main symptoms as thrombocytopenia and thrombus formation are extremely non-specific, which complicates the diagnosis of HIT. Special attention is paid to critically ill patients with already pronounced thrombocytopenia, in whom it is impossible to detect HIT based on the platelet count alone. In the article, we paid a lot of attention to diagnostic scales and diagnostic tests that allow timely diagnosis and treatment. Conclusions. The study suggests that a delay in the diagnosis of HIT leads to a worsening of the clinical outcome for patients, while a timely and correct diagnostic scenario allows for the prescription of alternative anticoagulants to prevent complications and obtain optimal treatment outcomes for patients with a negative HIT status.

Background

Female collegiate cross-country (XC) runners have a high incidence of running-related injury (RRI). Limited reports are available that have examined potential intrinsic factors that may increase RRI risk in this population.

Purpose

To examine the relationships between RRI, hip muscle strength, and lower extremity running kinematics in female collegiate XC runners.

Study Design

Prospective observational cohort.

Methods

Participants included twenty female NCAA collegiate XC runners from Southern California universities who competed in the 2019-20 intercollegiate season. A pre-season questionnaire was used to gather demographic information. Hip muscle strength was measured with isokinetic dynamometry in a sidelying open-chain position and normalized by the runner’s body weight (kg). Running kinematic variables were examined using Qualisys 3D Motion Capture and Visual 3D analysis. RRI occurrence was obtained via post-season questionnaires. Independent t-tests were used to determine mean differences between injured and non-injured runners for hip abductor muscle strength and selected running kinematics. Pearson correlation coefficients were calculated to examine relationships between hip muscle performance and kinematic variables.

Results

End-of-the-season RRI information was gathered from 19 of the 20 participants. During the 2019-20 XC season, 57.9% (11 of 19) of the runners sustained an RRI. There were no significant differences between mean hip abductor normalized muscle strength (p=0.76) or mean normalized hip muscle strength asymmetry (p=0.18) of injured and non-injured runners during the XC season. Similarly, no significant differences were found between mean values of selected kinematic variables of runners who did and who did not report an RRI. Moderate relationships were found between hip abductor strength variables and right knee adduction at footstrike (r=0.50), maximum right knee adduction during stance (r=0.55), left supination at footstrike (r=0.48), right peak pronation during stance (r=-0.47), left supination at footstrike (r=0.51), and right peak pronation during stance (r=-0.54) (all p≤0.05).

Conclusions

Hip abduction muscle strength, hip abduction strength asymmetry, and selected running kinematic variables were not associated with elevated risk of RRI in female collegiate XC runners.

Published: September 2024

A biodiversidade brasileira abrange seu vasto território composto por seis biomas distintos. No entanto, essa riqueza está sob ameaça devido à intensa ação antropogênica, o que inclui a exploração de recursos naturais. O tráfico de animais silvestres é uma prática ilícita que resulta na retirada de milhões de animais da natureza a cada ano, alimentando um mercado lucrativo nacional e internacional. Esta atividade representa uma ameaça alarmante à diversidade biológica, comprometendo ecossistemas e bem-estar animal. Apesar dos esforços das autoridades, essa prática criminosa persiste. Normativas jurídicas como a Constituição Federal de 1988 e a Lei de Crimes Ambientais estabelecem medidas coercitivas e preventivas para combater esse problema, atribuindo sanções aos infratores. Este estudo adota uma abordagem qualitativa utilizando o método dedutivo para analisar profundamente esse fenômeno, identificando suas causas, consequências, estratégias de contenção e as legislações pertinentes. O objetivo é aumentar a consciência sobre a importância da preservação da fauna silvestre e a urgência de ações efetivas para enfrentar essa ameaça à biodiversidade brasileira. O artigo conclui que apesar da regulamentação vigente há fragilidades sancionatórias e punitivas que se relacionam aos altos índices de apreensões.
