What Does Affect Theory Do? Or, How to Pay Attention to the Possibilities of Attending
Authors: Alhomoud Hiba
Published: November 2021

The present paper explores the role of affect theory in social and political critique, specifically in terms of how it relates to modes of attending in the context of theorizing. In this regard, I examine why affect theory has markedly reshaped the contours of social and political academic discourse in recent decades, and what alternatives to theorizing it introduces or enables new openings to. In order to answer these questions, I delve into the works of various scholars who use affect theory as a framework for theorizing. I posit that engaging in an affective mode of attending enables attention to structures of bifurcation rather than binaries, by conceptualizing theory in terms of beside-ness rather than beyond-ness. In doing so, I aim to shed light on what an affective mode of attending might be, and what affect theory can teach us about what it means to attend, or how to engage in alternative attendings. I conclude the paper with a consideration of the ‘So what?’ question—in other words, why is the attention to attending significant? By attending to the possibilities inherent in alternative attendings, affect theory illuminates that there need not be ‘outside-ness’ understood in the sense of ‘beyond-ness’ for there to be an out- side in the sense of an alternative. To attend to something from a different stance, which then conditions different contours for the possibilities enabled from that stance, means that there exist multiple ‘outsides’ from within the supposed ‘inside’.

The Impact of the Criminalization of HIV Non-Disclosure on the Health and Human Rights of “Black” Communities
Authors: Wilson Ciann
Published: November 2021

The criminalization of HIV non-disclosure has become a hot topic for discussion and debate amongst human rights advocates, HIV/AIDS service providers, and people infected and affected by HIV/AIDS. This paper explores the inherent problems with HIV non-disclosure laws. These laws are ambiguous and pose a serious threat to public health policy and programming by obstructing the fundamental human rights of people infected and affected by HIV/AIDS. Using a human rights framework, this paper explores the impact of non-disclosure laws on the health and rights of African, Caribbean, and Black-Canadian communities and proposes ways to address the shortcomings of HIV non-disclosure laws and inadequate social policies.
Understanding Health Equity: Key Concepts, Debates, and Developments in Canada
Authors: Khan Attia
Published: November 2021

Health inequalities exist and persist due to the quality and distribution of the social determinants of health, i.e., the day to day circumstances people live in. These circumstances are determined by governing policies and practices which are influenced by the State’s political ideology and its socio-economic structures. Using a political economy approach, this paper takes a critical review of the literature on health equity in the Canadian context and clarifies key concepts pertaining to health equity and human rights. Findings of this review show that Canada has been performing poorly in addressing growing health inequalities, in part because of Canada’s increasingly neo-liberal stance on public health over the last decade. This paper will argue that a human rights framework can offer a concrete tool for restructuring public policies and for taking action against these inequalities. By placing health equity on the policy agenda, Canada can help reduce social and income inequalities and optimize the health of its populations.
Determinants of domestic energy prices in Nigeria (1980-2020)
Authors:   Obafemi Awolowo University, Ile Ife, Osun State. Nigeria, Patrick Ologbenla
Published: November 2021

The study examined the factors that influence the domestic prices of petroleum using the price of premium motor spirit (PMS) in Nigeria from 1980 to 2020. The study employed Autoregressive Distributed Lag model for the data analysis. The scope of the data used from the analysis of the study ranges from 1980 to 2020. The study found out that there exist a positive relationship between petroleum pump price and inflation and the result is statistically significant at 5% level of significance. The study also discovered that both oil output and oil import are the prime factors affecting the prices of domestic energy in Nigeria. The study recommended that our refineries should be put in good shape so we can save the cost of having to export to other countries for refining as this contributed to the high cost of selling the product in Nigeria. The study also recommended diversification of the economy in favour of the real sectors as this will help provide more goods for exports thereby improving on the balance of payment.
Classification Approaches for Treating Low Back Pain Have Small Effects That Are Not Clinically Meaningful: A Systematic Review With Meta-analysis
Authors: Tagliaferri Scott D. , Mitchell Ulrike H. , Saueressig Tobias , Owen Patrick J. , Miller Clint T. , Belavy Daniel L.
Published: November 2021

Objective

To determine whether classification systems improve patient-reported outcomes for people with low back pain (LBP).

Design

Systematic review with meta-analysis.

Literature Search

The MEDLINE, Embase, CINAHL, Web of Science Core Collection, and Cochrane Central Register of Controlled Trials databases were searched from inception to June 21, 2021. Reference lists of prior systematic reviews and included trials were screened.

Study Selection Criteria

We included randomized trials comparing a classification system (eg, the McKenzie method or the STarT Back Tool) to any comparator. Studies evaluating participants with specific spinal conditions (eg, fractures or tumors) were excluded.

Data Synthesis

Outcomes were patient-reported LBP intensity, leg pain intensity, and disability. We used the revised Cochrane Collaboration Risk of Bias Tool to assess risk of bias, and the Grading of Recommendations Assessment, Development and Evaluation approach to judge the certainty of evidence. We used random-effects meta-analysis, with the Hartung-Knapp-Sidik- Jonkman adjustment, to estimate the standardized mean difference (SMD; Hedges' g) and 95% confidence interval (CI). Subgroup analyses explored classification system, comparator type, pain type, and pain duration.

Results

Twenty-four trials assessing classification systems and 34 assessing subclasses were included. There was low certainty of a small effect at the end of intervention for LBP intensity (SMD, −0.31; 95% CI: −0.54, −0.07; P = .014, n = 4416, n = 21 trials) and disability (SMD, −0.27; 95% CI: −0.46, −0.07; P = .011, n = 4809, n = 24 trials), favoring classified treatments compared to generalized interventions, but not for leg pain intensity. At the end of intervention, no specific type of classification system was superior to generalized interventions for improving pain intensity and disability. None of the estimates exceeded the effect size that one would consider clinically meaningful.

Conclusion

For patient-reported pain intensity and disability, there is insufficient evidence supporting the use of classification systems over generalized interventions when managing LBP. J Orthop Sports Phys Ther 2022;52(2):67–84. Epub 15 Nov 2021. doi:10.2519/jospt.2022.10761
THE ANTINOMY OF FREEDOM AND FATE IN DOSTOEVSKY’S LIFE: FROM UNCERTAINTY TO THE CHOICE OF HIS LIFE PATH (TO THE 200TH ANNIVERSARY OF THE WRITER’S BIRTH)
Authors:   State Fire Academy of EMERCOM of Russia, Kirichek A.
Published: November 2021

The first article of the series uses the method of biographical analysis to examine the development of the antithesis regarding freedom and fate, freedom and necessity in the period of the writer’s youth, when formation of his creative personality was developing. It is concluded that the struggle for freedom leads to ambivalence resulting in gaining his own path of life connected with literature. Dostoevsky at the same time plunges himself into the abyss of self-will which causes a number of severe trials associated with imprisonment.

Predicting pelvic congestion syndrome: Concomitant pelvic pain diagnoses do not affect venography or embolization outcomes
Authors: Macher Jared , Brahmbhatt Akshaar , Shetty Anisha , Chughtai Komal , Baran Timothy , Baah Nana Ohene , Dogra Vikram
Published: November 2021

Objectives:

Pelvic congestion syndrome (PCS) is a challenging diagnosis to make secondary to nonspecific presenting symptoms and imaging findings. This retrospective review aims to discern predictive factors which can guide the decision to perform catheter-based venography and prognosticate outcomes.

Material and Methods:

A retrospective analysis of patients who underwent catheter venography for PCS between January 2014 and December 2019 was performed. Multiple factors, including patient demographics, clinical history, pre-procedural imaging, venographic findings, and treatment outcomes 180 days post-procedure, were included in the analysis. Venographic findings were used to separate patients into two groups (positive or negative), with these factors compared across groups. Regression analysis controlled for the confounding effects of age and body mass index (BMI). Treated subjects were separated based on outcome (partial, no response, complete response, or technical failure), and comparisons were performed.

Results:

Eighty patients were included in the initial analysis. Two patients were excluded due to prior embolization or portal hypertension. Seventy-eight patients were included in the final analysis. Sixty-two patients had positive findings, and 16 had no venographic findings to suggest PCS. A history of prior pregnancy was a significant predictor of positive venographic results (odds ratio = 5.99, P = 0.007). BMI was significantly lower in those with positive venographic results (P = 0.047). Presence of concomitant diagnoses did not affect venographic findings or treatment outcomes. No factors predicted treatment outcomes. Five of the treated patients had subsequent successful pregnancies.

Conclusion:

A lower BMI supports the decision to perform venography for suspected PCS. In addition, patients who carried concomitant potentially confounding diagnoses for chronic pelvic pain were found to have similar rates of venographic findings suggesting PCS, as well as similar treatment outcomes.

Blepharoptosis is currently a serious pathology, the treatment of which does not always bring a satisfactory result. The article provides a review of the literature, describes the methods of surgical treatment of this ophthalmopathology. Each method is distinguished by indications, outcomes, efficiency. The method of surgical intervention depends on the cause of ptosis, the function of the levator muscle, the patient's age, visual acuity and a number of other indicators, but the main criteria are the degree of preservation of the levator function and lowering of the upper eyelid. The classic algorithm for treating patients with blepharoptosis involves shortening the levator or suspending the muscle that raises the upper eyelid to the eyebrow. Key words: ptosis of the upper eyelid, resection of the levator, function of the levator, operations of suspending type.

В статье представлены результаты комплексного исследования медного боевого топора абашевской культуры, происходящего с территории Мало-Кизильского селища. Топор исследовался методами нейтронной томографии и радиографии, электронной сканирующей микроскопии; публикуются результаты его исследования методом ОЭСА. В результате установлено, что топор отлит из мышьяковистой меди месторождения Таш-Казган; специального воздействия на процесс охлаждения отливки не зафиксировано, отливка выполнена качественно, вредное воздействие растворимых примесей снивелировано, в металле выявлен малый процент литейных дефектов (0,18 % от его общего объема). Все это позволяет предположить его использование в качестве оружия ближнего боя, о чем косвенно свидетельствует и характер травм, зафиксированных на черепах из Пепкинского кургана. Радиоуглеродная AMS-дата для коллективного захоронения из этого могильника позволяет отнести время распространения подобного оружия в Среднем Поволжье к периоду к концу III или рубежу III-II тыс. до н. э.

The paper reports on the comprehensive study of a copper battle axe attributed to the Abashevo culture which was discovered at the Malo-Kizilskoe open settlement. The battle axe was examined by neutron tomography and radiographic analysis, and electron scanning microscopy methods; the paper provides results of its examination by optical emission spectrometry. The analysis established that the axe was cast from the copperarsenic ore coming from the Tash-Kazgan deposit; special treatment during the cast cooling was not recorded, casting is of good quality. Harmful effect of dissoluble impurities was reduced to minimum, the metal shows a small percentage of recorded casting defects (0,18 % of its total volume). All this suggests that it was used as a close combat weapon which is also indirectly confirmed by the nature of injuries documented on the skulls from the Pepkino kurgan. The radiocarbon AMS-date of the multiple grave in this kurgan enables the authors to date the period when such weapons were used in the Middle Volga region to the end of III mill. BC or the transitional period from III to II mill. BC.

В статье представлены результаты изучения шести краниоскопических признаков на 487 черепах раннего и среднего этапов эпохи бронзы из степной и лесостепной зон Восточной Европы. Выборки сформированы в основном по культурно-территориальному принципу. Межгрупповая изменчивость изученных признаков анализировалась с помощью таблиц сопряженности, точного критерия Фишера и метода главных компонент. Зафиксировано значительное морфологическое разнообразие локальных групп ямной культуры, сопоставимое с различиями между современными географически отдаленными европеоидными популяциями разного происхождения. Отмечено сходство носителей полтавкинской культуры и населения катакомбных культур, проживавших к северу от нижнего течения Дона. Происхождение носителей катакомбных культур более южных регионов - вдоль левых притоков Нижнего Дона, в волго-донском междуречье и в Северо-Западном Прикаспии - вероятно, связано с населением Кавказа и Закавказья.

The paper explores six cranioscopic attributes on 487 skulls dating to the early and the middle stages of the Bronze Age. The skulls originate from the steppe and the forest-steppe belts in Eastern Europe. The samples were selected mostly based on the cultural and regional principle. The inter-group variability of the attributes was analyzed with the help of contingency tables, the Fisher exact test and the principal components method. The analysis revealed substantial morphological diversity of the Yamnaya local groups which is comparable with the differences between modern geographically remote Caucasian populations of different origin. The paper highlights resemblance between the Poltavka individuals and the individuals from the Catacomb cultures who lived north of the Lower Don region. The origin of the Catacomb individuals inhabiting the regions located further to the south along the left tributaries of the Lower Don, the Volga-Don interfluve and the northwestern Caspian region is apparently linked to the population of the Caucasus and Transcaucasia.
AND SETTLEMENTS AT THE UPPER PALEOLITHIC RAKHAT SITE (LAYER 2) IN SOUTHEASTERN KAZAKHSTAN

Published: November 2021

История изучения верхнего палеолита Казахстана начинается с 1940-х гг. К сегодняшнему моменту открыты единицы стоянок с погребенными культурными останками. На некоторых из них в разное время фиксировались уровни обитания с остатками поселений, содержавших углубленные очаги, кострища, прокалы и т. д. Но подробные публикации этих материалов отсутствуют. Неудовлетворительная сохранность органических останков и продуктов горения в лессовидных суглинках мешали полноценному изучению и уверенной интерпретации различного рода объектов. В 2019 г. на стоянке Рахат удалось обнаружить культурные слои (слои 1-3) с каменными находками и археологическими объектами в виде ям различной функциональной принадлежности. В статье делается попытка обследовать и структурировать объекты с выделением жилой площадки в наиболее информативном культурном слое 2. В совокупном единстве каменный инвентарь из слоев 1-3 стоянки Рахат находит аналогии среди памятников начала эпипалеолита Ближнего Востока и Средней Азии (кебаран, ранний зарзиан, ~20-18 тыс. л. н.).

The history of studies related to the Upper Paleolithic in Kazakhstan began in the 1940s. Very few sites with buried human remains have been discovered so far. Some sites reveal occupation layers with remains of settlements and traces of sunken hearths, fire pits, calcined fragments, etc., dating to different periods. However, there are no relevant publications of these materials. Poor preservation conditions of organic residue and combustion products in loess-like loams prevent scholars from studies of all aspects of various objects and offer their interpretation with confidence. Excavations conducted at Rakhat in 2019 revealed occupation layers (layers 1-3) with stone finds and archaeological objects such as pits of various functions. The paper attempts to explore and present these objects in a structured mode in order to identify a dwelling site in occupation layer 2, which is the most informative. Stone tools coming from Rakhat layers 1-3 find analogies among the sites dating from the early stage of the Epipaleolithic of Near East and Central Asia (Kebaran, early Zarzian, ca. 20 000-18 000 years ago).

В работе представлены результаты петрографического анализа неолитической посуды Среднего Поволжья. Для изучения были отобраны 52 образца керамики елшанской и средневолжской культур с 11 памятников данного региона (рис. 1-4). Петрографический анализ керамики позволяет установить минералогический состав глин и отощителей, выявить рецептуру керамического теста, определить температуру и условия обжига, а также предположить возможные источники сырья. В результате проведенных исследований было установлено, что при изготовлении неолитической посуды существовала определенная региональная специфика. Полученные результаты не противоречат типологическим построениям исследователей, стратиграфическим наблюдениям и способствуют расширению понимания керамического производства в лесостепном Поволжье.

The paper reports on the results of petrographic analysis of Neolithic vessels from the Middle Volga region. The analysis included 52 ceramic samples of the Elshanka and the Middle Volga cultures originating from 11 sites of this region (Fig. 1-4). Petrographic analysis of ceramics offers an opportunity to identify the mineralogical composition of clays and tempering materials, identify the formulation of ceramic paste, determine temperature and conditions of firing as well as suggest possible raw material deposits. Our studies have found that manufacturing of Neolithic vessels had some regional distinctive features. The results obtained are quite consistent with typological classifications of researchers, and stratigraphical observations, adding essentially to our understanding of ceramic production in the forest-steppe belt of the Volga region.

В статье представлены новые результаты изучения керамики волосовской культуры территории Среднего Поволжья. В ходе обобщающего исследования было выявлено, что в ранней волосовской керамике преобладают прямые и утолщенные венчики. Преимущественно прямая профилировка сосудов. Высок процент орнаментированной посуды, общая схема орнаментации горизонтальная и вертикальная. В качестве элемента орнамента превалируют оттиски гребенчатого штампа. При подсчете коэффициента сходства 9 рассмотренных в работе памятников, относящихся к ранней волосовской культуре, было выявлено, что наиболее высокие коэффициенты сходства получены при подсчете по формам венчиков и элементам орнамента. По результатам технико-технологического анализа также выражена стандартизация рассматриваемых материалов.

The paper presents new results of study of ceramics from the Volosovo culture sites located in the Middle Volga region which is important for research of the Volosovo culture. This synthesis-oriented research has found that straight and thick rims predominate among the early Volosovo ceramics. Vessel profiling is predominantly straight. The ornamented vessels account for a large percentage share of the found vessels, the decoration pattern is organized horizontally and vertically. The comb stamp imprints predominate as a decorative element. The calculations of the similarity coefficient for nine sites attributed to the Early Volosovo culture demonstrate that the highest similarity coefficients have been obtained for rim shapes and decorative pattern elements. The results of the technical and technological analysis also demonstrate standardization of the analyzed materials.

Даргавский могильник является одним из уникальных памятников на юге России. где сохранились немногочисленные. но информативные находки из органики. В 2019 г. в ходе раскопок Терским отрядом ИА РАН катакомб № 97 (IX в.) и 98 (втор. пол. VIII - перв. пол. IX в.) для палинологического анализа отобрано три образца: № 1 - содержимое кожаного мешочка (катакомба № 97). № 2 - бусина из помета (катакомба № 97) и № 3 - грунт из стеклянного стакана (катакомба № 98). По данным палинологического анализа установлено содержимое кожаного мешочка (мука или зерно) и стеклянного стакана (напиток. содержащий культурные злаки. или хлебное изделие. накрывающее стакан). принадлежность бусины. изготовленной из помета мелкого рогатого скота, определен сезон погребения в катакомбе № 97 (два первых летних месяца). Наличие хелицер клещей в мешочке и телиоспор головни в стакане может свидетельствовать о зараженности запасов вредителями и патогенными грибами. Результаты определения шерсти из катакомбы № 97 позволяют предположить, что на погребенной была верхняя одежда из овечьей шкуры. Изученные находки тесно связаны с дохристианскими представлениями оставившего могильник раннесредневекового населения о непосредственной связи мира мертвых с плодородием и урожаем.

The Dargavs cemetery is one of the unique sites in the South of Russia that has preserved few but informative organic residue. In 2019 during the excavations of catacombs No. 97 (9 century) and No. 98 (second half of the 8 - first half of the 9 century the Terskiy team of the Institute of Archaeology, RAS, selected three samples for palynological analysis. Sample No. 1 is contents of a small leather bag (Catacomb No. 97); Sample No. 2 is a bead from animal droppings (catacomb No. 97) and Sample No. 3 - soil from a glass tumbler (catacomb No. 98). The palynological analysis established the contents of the leather bag (flour or grains) and the glass tumbler (a drink containing cultivated gramineous plants or some bread stuff placed over the glass tumbler), the origin of the bead made from droppings of goats or sheep. The season of the burial in catacomb No. 97 was determined as the first two summer months. Presence of the chelicerae of ticks in the bag and teliospores of blight in the tumbler suggests that the stored food was contaminated with pests and pathogenic fungi. The determination of wool in catacomb No. 97 suggests that the buried person wore an outer coat made from sheep skin. The examined finds are closely related with pre-Christian beliefs of the early medieval population that has left this cemetery concerning direct links between the world of the dead and fertility and harvest.

Проведены исследования кинетических закономерностей сушки измельченного и обезэфиренного водяным паром сырья кориандра. Рассмотрены существующие технологии сушки растительного сырья и обосновано, что для обезэфиренного сырья кориандра наиболее целесообразной является кондуктивная сушка. Показано, что кондуктивная сушка обезэфиренного кориандра на малотоннажных предприятиях может осуществляться в жаровнях, применяемых при производстве растительных масел. Определены исходные массы образцов обезэфиренного кориандра и массовых долей влаги и летучих веществ в них, проведена сушка образцов в сушильном шкафу при температурах 100°С и 115°С, при этом каждые 10 мин производили взвешивание и рассчитывали убыль массы образцов. По результатам исследований построены кривые сушки u = f(τ) и кривые скорости сушки N = f(u) обезэфиренного кориандра. Выявлено, что для исследуемого диапазона температур сушки критическое влагосодержание обезэфиренного кориандра одинаково и равно 43%. По полученным данным определены интенсивность и скорость испарения влаги в 1-м и 2-м периодах сушки. Результаты проведенных исследований могут быть использованы при анализе работы и расчетах оборудования для реализации процесса сушки обезэфиренного кориандра в производстве.

Kinetic regularities of drying of coriander grinded and deprived of essential oils by steam distillation have been investigated. Existing technologies of drying for plant materials have been considered. It has been proved on reasonable grounds that conductive drying is more expedient for raw materials based on coriander deprived of essential oils. It has been shown that in small scale enterprises conductive drying of coriander deprived of essential oils can be carried out in heaters used for production of vegetable oils. Initial masses of samples of coriander deprived of essential oils were determined including mass fractions of moisture and the content of volatile substances in them. Samples were dried in a cupboard drier at the temperature 100°C and 115°C, weighed every 10 minutes and their mass loss was evaluated. Using the obtained data, curves of drying u = f(τ) and curves of drying speed N = f(u) of coriander deprived of essential oils were drawn. It has been found out that for the examined range of temperatures the critical moisture content for coriander deprived of essential oils is the same and equal to 43%. According to the obtained data, the intensity and the speed of water evaporation at the first and the second stages of drying have been determined. The results of the carried out research can be used in the analysis of performance and estimation of equipment to put the process of drying of coriander deprived of essential oils into operation.

Приведен обзор применяемых в настоящее время способов биологического контроля заболеваний растительного сырья. Несмотря на быстрый рост научных исследований в области продления сроков хранения растительного сырья, предотвращение его потерь от микробиальной порчи по-прежнему является актуальной задачей. Отмечено, что химические методы контроля заболеваний растений являются токсичными и представляют угрозу для здоровья потребителя; в настоящее время ведется поиск альтернативных, более безопасных и экологичных способов контроля заболеваний продуктов растениеводства. Показано, что таковыми являются методы биологического контроля микробиальной порчи. Рассмотрены биопрепараты, пригодные для борьбы с фитопатогенами растений, а также новые перспективные штаммы бактерий, которые могут быть применены для борьбы с микробиальной порчей. Сделан вывод о перспективности разработок технологий биологического контроля микробиальной порчи продукции растениеводства.

One-Step Biocatalytic Synthesis of Sustainable Surfactants Using Selective Amide Bond Formation

Published: November 2021

N-alkanoyl-N-methylglucamides (MEGAs) are non-toxic surfactants widely used in pharmaceutical and biochemical applications and hence more sustainable syntheses towards these compounds are highly desired. Here we present an aqueous, enzymatic synthesis route towards MEGAs and analogues using carboxylic acid reductase (CAR), which has been engineered to catalyse amide bond formation (CAR-A). Compared to lipase catalysed reactions, this biocatalyst is capable of selective amide bond formation between amino-polyols and fatty acids without the competing esterification reaction being observed. The wide substrate scope of CAR-A catalysed amidation was exemplified by the synthesis of 16 amides including several commercially relevant targets. The ATP co-factor could be recycled from cheap polyphosphate using a kinase. This work establishes acyl-phosphate mediated chemistry as a selective strategy for biocatalytic amide bond formation in the presence of competing alcohol functionalities.
Chiral control of spin-crossover dynamics in Fe(II) complexes

Published: November 2021

Iron-based spin-crossover (SCO) complexes hold tremendous promise as multifunctional switches in molecular devices. However, real-world technological applications require the excited high-spin (HS) state to be kinetically stable – a feature that has only been achieved at cryogenic temperatures in the light-induced excited spin-state trapping effect. Here we demonstrate HS state trapping by controlling the chiral configuration of FeII(4,4’-dimethyl-2,2’-bipyridine)3 in solution, associated for stereocontrol with enantiopure ∆- or Λ-TRISPHAT anions. We characterize the HS state relaxation using a newly developed ultrafast circular dichroism technique in combination with transient absorption and anisotropy measurements. We find that the decay of the HS state is accompanied by ultrafast changes of its optical activity, reflecting the coupling to a symmetry-breaking torsional twisting mode, contrary to the commonly assumed picture. Furthermore, we show that the diastereoselective ion-pairing with the enantiopure anions suppresses the vibrational population of the identified twisting mode, thereby achieving a four-fold extension of the HS lifetime. Transferred to the solid state, this novel strategy may thus significantly improve the kinetic stability of iron(II)-based magnetic switches at room temperature.
Cell-free biosynthesis of ω-hydroxy acids boosted by a synergistic combination of alcohol dehydrogenases

Published: November 2021

The activity orchestration of an unprecedented cell-free enzyme system with self-sufficient cofactor recycling enables the step-wise transformation of aliphatic diols into -hydroxy acids at the expense of molecular oxygen as electron acceptor. The efficiency of the biosynthetic route was maximized when two compatible alcohol dehydrogenases were selected as specialist biocatalysts for each one of the oxidative steps required for the oxidative lactonization of diols. The cell-free system reached up to 100% conversion using 100 mM of linear C5 diols, and performed the dessymetrization of prochiral branched diols into the corresponding -hydroxy acids with an exquisite enantioselectivity (ee > 99%). Green metrics demostrate a superior sustanability of this system compared to traditional metal catalysts and even to whole cells for the synthesis of 5-hydroxy petanoic acid. Finally, the cell-free system was assembled into a consortium of heterogeneous biocatalysts that allowed the enzyme reutilization. This cascade illustrates the potential of systems biocatalysis to access new heterofunctional molecules such as -hydroxy acids.
Strategies for Computer-Aided Discovery of Novel Open-Shell Polymers

Published: November 2021

Organic π-conjugated polymers with a triplet ground state have been the focus of recent research for their interesting and unique electronic properties, arising from the presence of the two unpaired electrons. These polymers are usually built from alternating electron-donating and electron-accepting monomer pairs which lower the HOMO-LUMO gap and yield a triplet state instead of the typical singlet ground state. In this paper we use density functional theory calculations to explore the design rules that govern the creation of a ground state triplet conjugated polymer, and find that a small HOMO-LUMO gap in the singlet state is the best predictor for the existence of a triplet ground state, compared to previous use of pro-quinoidal character. This work can accelerate the discovery of new stable triplet materials by reducing the computa- tional resources needed for electronic-state calculations and the number of potential candidates for synthesis.
