Spins at work: probing charging and discharging of organic radical batteries by electron paramagnetic resonance spectroscopy
Organic radical batteries (ORBs) are a promising class of electrochemical power sources employing organic radicals as redox-active groups. This article reports on the development of a versatile on-substrate electrode setup for spectroelectrochemical Electron Paramagnetic Resonance (EPR) measurements on redox conductive polymers for ORBs. Quantitative in operando EPR experiments performed on electrochemical cells with a di-TEMPO Ni-Salen polymer as active electrode material demonstrate a strong decrease in the number of paramagnetic centers upon oxidizing the film. The distinct EPR signatures of the TEMPO-containing polymer and its fragments in different molecular environments are used to study its degradation upon repeated cycling. A comparison between the number of EPR-active sites and the number of electrochemically active charges, as measured by cyclic voltammetry, provides information on the nature of the degradation process. Low-temperature ex situ pulse EPR measurements on the oxidized polymer film reveal the spectrum of dilute nitroxide species, which may be associated with electrochemically inactive islands. These experiments pave the way for advanced EPR techniques for accurately determining distances between adjacent paramagnetic centers and thus for identifying performance-limiting loss mechanisms, which can eventually help develop strategies for making ORBs powerful contenders on the path towards sustainable electrochemical power sources
a [Ni(Salen)]‐TEMPO redox‐conducting polymer for organic batteries
Redox-active nitroxyl-containing polymers are promising candidates as possible replacements for inorganic based energy-storage materials, due to their high energy density and fast redox kinetics. One challenge towards the implementation of such a system is the insufficient electrical conductivity, impeding the charge collection even with highly conductive additives. Herein, the first implementation of a polymeric bis(salicylideniminato) nickel (NiSalen) conductive backbone as an active charge-collecting wire is reported. NiSalen simultaneously serves as a charge collector for nitroxyl pendants and supports the redox capacity of the material. This novel polymer exhibits a specific capacity of up to 91.5 mAh g−1, retaining 87 % of its theoretical capacity at 800 C and more than 30 % at as high as 3000 C (66 % capacity retention after 2000 cycles). The properties of the new material upon operation was studied by means of operando electrochemical methods, UV-Vis, and electron paramagnetic resonance spectroscopy
Label-free macroscopic fluorescence lifetime imaging of brain tumors
Advanced stage glioma is the most aggressive form of malignant brain tumors with a short survival time. Real-time pathology assisted, or image guided surgical procedures that eliminate tumors promise to improve the clinical outcome and prolong the lives of patients. Our work is focused on the development of a rapid and sensitive assay for intraoperative diagnostics of glioma and identification of optical markers essential for differentiation between tumors and healthy brain tissues. We utilized fluorescence lifetime imaging (FLIM) of endogenous fluorophores related to metabolism of the glioma from freshly excised brains tissues. Macroscopic time-resolved fluorescence images of three intracranial animal glioma models and surgical samples of patients\u27 glioblastoma together with the white matter have been collected. Several established and new algorithms were applied to identify the imaging markers of the tumors. We found that fluorescence lifetime parameters characteristic of the glioma provided background for differentiation between the tumors and intact brain tissues. All three rat tumor models demonstrated substantial differences between the malignant and normal tissue. Similarly, tumors from patients demonstrated statistically significant differences from the peritumoral white matter without infiltration. While the data and the analysis presented in this paper are preliminary and further investigation with a larger number of samples is required, the proposed approach based on the macroscopic FLIM has a high potential for diagnostics of glioma and evaluation of the surgical margins of gliomas
Оценка качества жизни с помощью вопросника Health Utilities Index у детей c бронхиальной астмой тяжелого персистирующего течения на фоне лечения омализумабом
Background. Quality of life (QoL) is an important parameter that provides additional information about changes in health status. Objective. Our aim was to study the change in QoL of patients with severe persistent bronchial asthma (BA) during the treatment with genetically engineered biological preparation (GIBP) omalizumab in addition to daily background therapy. Methods. The QoL assessment was conducted using the Health Utilities Index Mark 3 and Mark 2 (HUI3, HUI2) questionnaires at two points (1st point and 2nd point — in 6 months) in 47 children with severe BA at the age of 13 (7; 17) years, 72% of them are boys. At the same points, QoL was evaluated using the PAQLQ (S) specialized pediatric questionnaire (Standardized Pediatric Asthma Quality of Life Questionnaire). Results. Depending on the duration of omalizumab therapy, all children were divided into 5 groups: 1st group — children who did not receive treatment with monoclonal antibodies at the 1st point; in 2, 3, 4, 5-th groups, the QoL assessment was performed on GIBP treatment for different time. In children of the 1st group whose QoL was evaluated before starting GIBP therapy and in 6 months, a statistically significant change in scores on the Health Utilities Index questionnaire was noted: the multi-attribute indices HUI2 and HUI3 improved, respectively, by 21.3 and 10.71% (p = 0.041 and 0.086). According to the HUI2 classification system, a significant improvement in the emotion attribute was revealed, which positively correlated with the overall indicator and the emotion indicator of the PAQLQ (S) questionnaire. In the remaining groups, the indicators of the Health Utilities Index questionnaire did not change significantly. Conclusion. The study results showed that the dynamics of the quality of life in children with severe persistent BA is an important additional criterion in a comprehensive assessment of the efficacy of targeted bioengineering therapy. Качество жизни (КЖ) — важный параметр, обеспечивающий дополнительную информацию об изменениях в состоянии здоровья. Цель исследования — изучить изменение КЖ пациентов с бронхиальной астмой (БА) тяжелого персистирующего течения на фоне лечения генно-инженерным биологическим препаратом (ГИБП) омализумабом в дополнение к ежедневной базисной терапии. Методы. Оценка КЖ проводилась с помощью вопросников Health Utilities Index Mark 3 и Mark 2 (HUI3, HUI2) в двух точках (1-я точка и 2-я точка — через 6 мес) у 47 детей с тяжелым течением БА в возрасте 13 (7; 17) лет, из них 72% мальчиков. В этих же точках КЖ было оценено с использованием специализированного детского вопросника PAQLQ(S) (Standardised Paediatric Asthma Quality Of Life Questionnaire). Результаты. В зависимости от длительности терапии омализумабом все дети были разделены на 5 групп: 1-я — дети, которые в 1-й точке не получали лечение моноклональными антителами; во 2, 3, 4, 5-й группах оценка КЖ проводилась на фоне ГИБП в течение разного времени. У детей 1-й группы, у которых КЖ оценивалось до начала терапии ГИБП и через 6 мес, отмечалось статистически значимое изменение баллов по вопроснику Health Utilities Index: мультиатрибутные индексы HUI2 и HUI3 улучшились, соответственно, на 21,3 и 10,71% (р=0,041 и 0,086); по данным классификационной системы HUI2 выявлено достоверное улучшение атрибута «эмоции», который положительно коррелировал с общим показателем и показателем «эмоциональная сфера» вопросника PAQLQ(S). Заключение. Результаты исследования показали, что динамика качества жизни у детей с тяжелой персистирующей БА является важным дополнительным критерием в комплексной оценке эффективности применения таргетной биоинженерной терапии.

British Historian Paul Dukes on the Regions of Russia in the Context of its History
The article is devoted to the study of the history of Russia’s northern and eastern regions by Paul Dukes (1934–2021), a fellow of the Royal Society of Edinburgh, Professor Emeritus at the University of Aberdeen. Based on the British historian’s scholarly publications and his travelogue sharing his personal impressions of Russian hinterland, the article presents his understanding of the specifics of the Russian North, the Urals, and the Far East in the history of Russia. It has been shown that the British historian made a significant contribution to English-language historiography by creating an image of the regions that are peripheral but nonetheless very significant for Russia and the world. He worked in the genre of analytical narrative and his scholarship was based upon the works of Russian, Soviet, and Western historians, historical documents, and his own impressions. Historicism, objectivism, broad outlook, comparativism, and the ability to adjust his research optics to micro- and macromodes depending on the tasks and specifics of the study were typical traits of the style of Paul Dukes’ writing. The image of the Russian North was shaped by the personal impressions of the British traveler; as an outside observer, he captured the details and circumstances of the post-Soviet period, which, however, did not spoil the warmth of perception of traditional values and hospitability of the northerners. Path-breaking in the English-language historiography, his monograph on the history of the Urals from the early Russian colonization to the present day reveals to the foreign reader the significance of the largest metallurgical region for the development of Russia and the world. Manchuria in Russian and Soviet history is considered in the context of intense international rivalry
