TRITERPENE GLYCOSIDES AS PLANT GROWTH REGULATORS: POTENTIAL AND PROSPECTS FOR USE (RE-VIEW)
Authors: Davidyants Eleonora Sergeyevna
Published: May 2023

The increased interest in the study of the growth-regulating activity of triterpene glycosides (TG) in recent years is largely due to the need to create new highly effective environmentally friendly plant growth biostimulants, the use of which is considered as an important strategy in managing the productivity and stress resistance of agricultural crops. Тhe review presents information available in the literature on phytoregulatory activity TG with an emphasis on their growth-stimulating properties. The physiological effects of TG in bioassays on phytohormonal activity are considered. The auxin- gibberellin- and cytokinin-like effect of TG on growth and metabolism (changes in the activity of enzymes: α-amylase, peroxidase, catalase, polyphenol oxidase, IAA oxidase, nitrate reductase, chlorophyll and protein content), was shown depending on the structure of TG, concentration and the tested plant. The issues of the mechanism of the growth-stimulating action and the possible involvement of TG and free triterpenes in physiological processes in plants are discussed. The relationships between the structure and phytoregulatory activity of TG was analyzed. The effect of exogenous TG and triterpenoids on plants under abiotic stresses, as well as the possibility of using some TG, extracts of saponin-bearing plants (Сamellia sp., Silphium perfoliatum, Medicago sativa, Glycine max, Vigna radiata, Glycyrrhiza glabra, Moringa oleifera, Solidago gigantea, Centella asiatica, Eclipta alba, Quillaja saponaria, Bacopa monnieri et al.) and plant extracts containing triterpenoids (Abies sibirica, Betula sp.) in crop production as plant growth regulators, is considered.

Authors: Usmanova Nargiza Kudiratullaevna , Yuldasheva Nigora Karimovna , Gusakova Svetlana Dmitriyevna , Botirov Erkin Khozhiakbarovich
Published: May 2023

Lipids and phenolic compounds of seeds with an admixture of the leaf mass of Melilotus officinalis (L.) Pall, Fabaceae family, have been studied. It was found that the content of neutral lipids (NL) in seeds is 2.93%, polar lipids (PL) – 3.15%. triacylglycerides and free fatty acids (LC) dominate in NL, which are accompanied by hydrocarbons, carotenoids, esters of phytosterols with LC, triterpenols, phytosterols and modified chlorophylls. Phytosterols were the main component of unsaponifiable substances isolated from NL, and hydrocarbons, carotenoids, phytosterols, aliphatic alcohols and triterpenols were also found. Glycolipids (GL), consisting of esters of sterylglycosides, sterylglycosides, monohalactosyl- and digalactosyldiglycerides, predominate in PL. Phospholipids (FL) include phosphatidylethanolamines, phosphatidylcholines, and phosphatidylinosites.

Twelve components were identified in the composition of fatty acids (LC) of NL, in GL and FL – 13 components with a significant predominance of saturated fatty acids (52.95–85.73%), mainly palmitic 16:0. A feature of fatty acids of NL is the high (16.67%) content of lauric 12:0 acid, which is also present in GL (3.87%), and in FL (1.62%).

Three individual phenolic compounds were isolated from various fractions of the 75% alcohol extract of the aboveground part, which, based on the study of spectral data, were identified with p-hydroxybenzoic, p-hydroxycoric acids and androsin.

Authors: Dronova Anastasiya Vladimirovna , Dyakova Нина Алексеевна
Published: May 2023

This literature review is devoted to the tuberous yacon (Smallanthus sonchifolius), a perennial plant of the family Asteraceae, which is widely used in traditional medicine. Yacon tubers are characterized by a sufficiently high content of inulin for industrial production. The data provided in the review show that Smallanthus sonchifolius has a proven prebiotic effect due to its high content of fructooligosaccharides as well as other chemical compounds and has great potential as a prebiotic. In addition to the prebiotic effect, yacon has a wide range of pharmacological effects, including antidiabetic, hypoglycemic, hypolipidemic, anti-inflammatory, antitumor, immunostimulatory, antioxidant, antidepressant, hepatoprotective, spermatogenic, antibacterial, antifungal, antiparasitic, analgesic. Infusions made from yacon leaves can be not only effective agents against hyperglycemia, but also a relatively rich source of polyphenolic antioxidants. Yacon has potential as a plant supplement to treat male infertility and normalize low testosterone levels, such as in LOH-syndrome. The diversity of pharmacological action of yacon is due to the content of different groups of biologically active substances described in the review. The underground organs, leaves, and flowers of yacon contain various chemical compounds, including phenolic acids, sesquiterpene lactones, fructooligosaccharides of inulin type β (2→1), tannins, flavonoids, saponins, and anthracene derivatives.

A katolikus egyház társadalmi tanításának üzenete
Authors: Zsinka László
Published: May 2023

A Katolikus Egyház 2021-ben emlékezett meg XIII. Leó pápa Rerum novarum (1891) kezdetű enciklikája kibocsátásának 130. évfordulójáról. A nevezetes dokumentumot a katolikus társadalmi tanítás alapkövének szokták tekinteni, ami azóta sokat gazdagodott, és számottevő fejlődésen ment keresztül. Széleskörű hatása miatt nem meglepő, hogy az enciklika évfordulója a tudományos világban is visszhangot keltett. A Nemzeti Közszolgálati Egyetem például konferencia megszervezésével akarta kifejezésre juttatni a problémakör jelentőségét. Azóta Ferenc pápa másodszor érkezik Magyarországra, és a katolikus egyházfő látogatása a hívők lelki közösségének megerősítésén túl újult erővel veti fel az Egyház és a (poszt)modern társadalom közötti sokrétű kölcsönhatások kérdését. Különös figyelmet érdemel e téren a katolikus szociáletika, aminek eredeti szemlélete alkotó módon járult hozzá a 20. század politikai és gazdasági gondolkodástörténetének alakulásához.
A magyar mezőgazdaságban rejlő lehetőségek
Authors: Szabó Bálint
Published: May 2023

A közepes fejlettségi csapdából való kitörésnél mind a hazai és nemzetközi szakirodalom, mind a közbeszéd (helyesen) a tudás alapú gazdaság és a magas hozzáadott értékű munkahelyek megteremtésére helyezi a hangsúlyt. Egy jól funkcionáló társadalomban azonban az állampolgárok mentális és fizikai egészségi állapotának javítása is megkerülhetetlen nemzetstratégiai szempont lenne. Kicsit profánul megfogalmazva azért, mert egy egészségesebb munkaerő produktívabb, magasztosabban szemlélve pedig azért, mert az esélyek egyenlőségét megteremtve egy működő népegészségügyi rendszer senkit sem hátráltathatna az önmegvalósításban. Ennek persze egyik legfontosabb építőeleme a betegellátás, érdemes azonban a prevencióról, jelen esetben a táplálkozásról is szót ejteni, kiváltképp azért, mert a magyar felnőttkorú lakosság 24,5%-a tekinthető túlsúlyosnak, ami az elmúlt években nem, hogy csökkent volna, hanem emelkedett (noha meg kell jegyezni az emelkedő tendencia pár kivétellel valamennyi EU-tagországra igaz)[1].
Mezőgazdasági átalakulás a 21. században – Mi jön a traktor után?

Noha a negyedik ipari forradalomhoz kötődő technológiai újításokat legtöbbször az infokommunikációs szektorhoz társítjuk, ezeknek a fejlesztéseknek az esernyője a gazdaság minden területét, így a mezőgazdaságot is magában foglalja. Az agráriumban bekövetkező foglalkoztatáscsökkenés egy gazdaság fejlődésével természetesen relatíve és abszolút is csökken (Magyarországon például háromszor annyian dolgoztak az agrárszektorban a rendszerváltáskor, mint most). A technológiai fejlődés azonban nemcsak a munkahelyek megszűnésével, hanem új munkakörök létrejöttével is jár. A most kibontakozóban lévő digitális forradalom a mezőgazdaságban ezt különösen igazzá teszi, a korszerű eljárásoknak köszönhetően egy teljesen új szolgáltatóipar fog ráépülni az agráriumra.

Type 2 diabetes with obesity and hypertension: prevalence and sociodemographic risk factors in Yemen
Authors: Mareai S. S. , Gawli K.
Published: May 2023

BACKGROUND: Diabetes Mellitus is a rapidly growing and challenging health issue of the 21st century. Type 2 diabetes (T2D) is a major risk factor for obesity and hypertension (HTN). The prevalence of HTN and obesity in T2D patients is not well documented in the country of Yemen. AIM: The focus of this study was to assess the prevalence of hypertension and obesity in patients with type 2 diabetes mellitus in Yemen.

METHODS: A cross-sectional study was carried out in Dhamar city hospitals. Patients diagnosed with diabetes (300 males and females: 30 years old and/or above) visiting an endocrinology and diabetes clinic in Dhamar city hospital for the first time were examined and evaluated for blood glucose levels, mode of treatment, duration of the disorder and body mass index. Socio-demographic and clinical data were collected using pretested questionnaires. Ethical approval was obtained from corresponding ethical committees from Dhamar University and hospitals. Data were analyzed using SPSS 23 version.

RESULTS: The prevalence of overweight and/or obesity in T2D was 60.67%, and hypertension was 35.66%. The occurrence of T2D was predominant in females (56.33%), patients with an age over 50 years (61%), and rural dwellers (74%). The mode of treatment was mainly through oral antihyperglycemic and hypoglycemic agents (79.3%). A large population (66.3%) showed poor control of blood glucose levels ranging from more than 131 to 500 mg/dL and the type of work these patients were involved in was mostly physically inactive (64%). The body mass index revealed that more than 35% were found to be overweight and 23% to be obese. Patients with hypertension and undergoing treatment for the same showed a significant (P < 0.001) increase in blood glucose level compared to those who were not diagnosed with HTN.

CONCLUSION: The prevalence of obesity, HTN, and poor glycemic control in patients with T2D is high, especially in females.

Published: May 2023

BACKGROUND: High prevalence of anemia in diabetes mellitus (DM) determines the relevance of studying its pathogenetic aspects, the role of anemia in DM complications development and the issue of differential diagnosis between iron deficiency anemia (IDA) and anemia of chronic disease (ACD)).

AIM: To establish the diagnostic value of classical parameters for diagnosing anemia in DM and propose an optimized algorithm for the differential diagnosis of ACD and IDA in DM type 1 and 2 using new markers.

MATERIALS AND METHODS: The observational, single-centre, comparative, controlled, single-stage study. Patients underwent assessment of glycated hemoglobin, creatinine, microalbuminuria; indicators of iron metabolism — hematocrit, the number of erythrocytes, reticulocytes, hemoglobin, serum iron, transferrin, ferritin, the level of soluble transferrin receptors (sTfR), sTfR/logFerpitin index, and inflammation markers — erythrocyte sedimentation rate (ESR), leukocyte count, high sensitive CRP and TNF-α. ROC-analysis was used to assess the differential diagnosis markers informative content.

RESULTS: We examined 135 patients: 51 with DM 1 and 84 with DM 2. The patients were stratified into groups based on anemia type: 1) ACD 2) IDA 3) latent iron deficiency 4) without ferrokinetics disorders. According to the ROC-analysis in DM patients, the following parameters had high information content in ACD. ESR — sensitivity 92%, specificity 85%, diagnostic threshold 26.5 mm/h (area under the curve (AUC) 0.943; p<0.0001); leukocyte count — sensitivity 69%, specificity 64%, diagnostic threshold 7.50x109/l (AUC 0.727; p=0.007), microalbuminuria — sensitivity 71%, specificity 72%, diagnostic threshold 29.5 mg/l (AUC 0.744; p=0.003). In DM sTfR and the sTfR /logFerritin index had high information content in IDA at diagnostic thresholds different from those for general population. The sensitivity of sTfR 71%, the specificity 71%, diagnostic threshold 1.42 ng/mL (2.9 ng/mL for general population) (AUC 0.765; p=0.024). The sensitivity of sTfR/logFerritin index 100%, the specificity 97%, diagnostic threshold 1.48 (2.0 for general population) (AUC 0.983; p=0.024).

CONCLUSION: In differential diagnosis of IDA and ACD in DM, ESR, leukocyte count, microalbuminuria, sTfR and sTfR/logFerritin index have a high diagnostic value. This allows proposing them as additional markers for differential diagnosis of anemia in DM.

Research on the development and intelligent application of power environmental protection platform based on big data
Authors: Shao Dan , Shi Li Bin , He Zhi Guo , Guo Run Zhou
Published: May 2023

In order to improve the practical effect of the power environmental protection platform, this paper combines the big data technology to develop and design the power environmental protection platform. In this paper, a power factor correction (PFC) and resonant half-bridge joint controller is used to combine the traditional two-level topology into one-level topology. Moreover, this paper adopts a fixed frequency half-bridge LLC resonant converter with a simple control circuit to obtain a stable resonant half-bridge controller with a fixed output voltage. The choice of this overall power topology architecture can not only meet the design requirements, save costs and simplify the control of the circuit, but also improve the efficiency of the whole machine and the performance of the power environmental protection platform. The experimental research shows that the power environmental protection platform based on big data proposed in this paper can effectively improve the effectiveness of power environmental protection strategies.

The notices of new publications in magazines and newspapers were part of the marketing policy of publishers. The wording and format of these advertising columns in the, mainly London, newspapers reveal much about the sophisticated manner in which the editors communicated their purpose in marketing newly published books. Besides the reviews, it is here, in these brief notices and advertisements, that we can map out barely noticeable shifts in the early reception of Sterne’s fiction and his sermons (see Brandtzæg et al., “Advertising” 28). Digital archives such as ECCO, the Burney Collection, and British Periodicals are of great help today.

He joined the cause of the Hungarian War of Independence and was among thedefenders of the fortress of Komárom, led by György Klapka. After they surrendered, Schlesinger emigrated overseas, traveling from Liverpool to New York in December 1849. In the US, he met the Venezuelan General, Narciso López (1797-1851), andjoined his expedition, aimed at the liberation of Cuba from Spanish rule. The essay discusses the career of Schlesinger as a rubber entrepreneur in El Salvador and as a railroad constructor in Guatemala.
Culture and Language Maintenance Efforts of the Hungarian Community in San Diego
Authors: Forintos Éva
Published: May 2023

In this paper, I argue that members of the Hungarian community (who are assumed to be first-generation Americans) living in the city of San Diego, California and have assimilated into the mainstream culture of their adopted country, have developed anidentity that can be regarded as a combination of their native language and culture as well as their dominant language and culture. This distinctively dynamic identity contributes to the maintenance of their heritage language and culture. Through negotiating their identity via intentional code-mixing in their written discourse, they invite members of the mainstream group to learn about and become interested in their culture. Among the many types of significant influences that minority communitymedia can have on ethnic identity construction, there is an opportunity for the community to be present inside and outside of the group as well as operating as an essential communicator of culture and a creator of cultural artifacts. The illustrative material analyzed in this paper is sourced from the House of Hungary (San Diego) website and the latest issues of their newsletter.
“The Book Of eternal brass”: The Bible and the Laws in William Blake’s The [First] Book of Urizen and Emanuel Swedenborg’s The Last Judgment
Authors: Spalovszky Csaba József
Published: May 2023

William Blake was an artist and thinker whose character was as controversial as it was misunderstandable, even in his own time, let alone after his death. His works reflect a philosophical and theological system that is very diff erent from what we are used to in connection with the eighteenth and nineteenth centuries, more precisely, from our usual assumptions about the periods of the Enlightenment and Romanticism. The universe he created out of contemporary and earlier philosophical systems, the influence of religious movements like the Moravians and theologians like Emanuel Swedenborg or thinkers like Johann Kaspar Lavater, together with his own personal faith and idiosyncratic interpretations, might seem to be chaotic: a form of disorder, at least for the fi rst encounter. However, this apparent disorder is not a chaos, but the result of a new way of seeing the world, which is grounded in a unique understanding of the relationship between language and thinking.
"There's no cure for the Internet" - Surveillance, Spectatorship, and Sanctuary in Black Mirror
Authors: Novák Zsófia
Published: May 2023

The British-American anthology series Black Mirror (2011-2019) constructs delicately balanced worlds that are “just realistic enough to get under the viewer’s skin, yet just extreme enough to grab attention and not let go until [the] bleak resolution” (33). The episodes that I will examine here may be read as examples of surveillance capitalism’s modus operandi. “Hated in the Nation” and “Fifteen Million Merits” present over-technologized societies characterized by a complete lack of privacy, eliminating both sanctuary and exit—which, as Zuboff also contends, is closely correlated with the individual’s lack of agency in- or outside the (social) hive (444). Although the selected episodes are characterized by substantial differences in tone, setting, plot, and aesthetic and psychological strategies, surveillance and spectatorship— complicating boundaries between externality and internality—have central functions in both. Concerned both with the characters’ experience and with the audience’s position(ality) and identification processes in the act of viewing, this essay analyses the mechanics of the filmic text in the episodes, looking at how it problematizes the central issues of spectatorship, surveillance, and (the lack of) sanctuary.

Este trabajo presenta la viabilidad de los refrigerantes R1234ze(E) y R516A para ser usados en la refrigeración doméstica como reemplazo directo del R134a. Se evaluó un refrigerador doméstico instrumentado con el fin de caracterizar su desempeño. Se definió la carga óptima de refrigerante a través del mínimo consumo de energía, resultando una carga de 80 g para el R516A y 84 g para el R1234ze(E), lo que representó una carga menor con respecto al R134a (90 g). Acorde a la carga óptima, los principales resultados indicaron que ambos refrigerantes son viables para ser usados en la refrigeración doméstica, mostrando comportamientos térmicos similares en ambos compartimentos del refrigerador. Además, estos refrigerantes presentaron un menor consumo de energía en comparación al R134a. El R1234ze(E) mostró un incremento del 8% en el coeficiente de desempeño (COP, por sus siglas en inglés) con respecto al R134a. Así, el R1234ze(E) puede ser considerado como un refrigerante a largo plazo, mientras que el R516A puede ser una mejor opción mediante modificaciones al diseño del refrigerador, lo que ayuda a mejorar su COP.

Piadas de bêbado sem-vergonha: quebrando e reforçando o estereótipo
Authors: Gil Francisco Baptista
Published: May 2023

Partindo do discurso de Lucio Oliveira, por meio das suas histórias em quadrinhos humorísticas em Edibar, este texto tem como objetivo analisar os estereótipos sociais a partir dos pressupostos teóricos da Análise de Discurso. O nosso intuito é compreender como o humor de Edibar é articulado em torno dos estereótipos das funções sociais do homem e da mulher. Sabendo que os estereótipos são rótulos sociais, conceitos, ou modelos de imagem atribuídas a determinadas pessoas, pretende-se discutir como as referências a alguns padrões podem provocar o seu reforço ou a sua desconstrução como crítica social.Palavras-chave: Análise de Discurso; Estereótipos Sociais; Humor; Quadrinhos. Shameless drunk jokes: breaking and reinforcing stereotypesAbstract: Starting from Lucio Oliveira's discourse, through his comics and his graphic and humoristic work in Edibar, this text aims to analyze social stereotypes from the theoretical assumptions of Discourse Analysis. Our intention is to understand how humor is articulated around some stereotypes, the social roles of men and women in the marital context. Knowing that stereotypes are social labels. concepts, ideas or image models attributed to certain people, we intend to discuss how references to some standards can cause their reinforcement or their deconstruction as social criticism.Keywords: Discourse Analysis; Social Stereotyping; Humor; Comics.

Planning and execution of voluntary movement depend on the contribution of distinct classes of neurons in primary motor and premotor areas. However, timing and pattern of activation of GABAergic cells during specific motor behaviors remain only partly understood. Here, we directly compared the response properties of putative pyramidal neurons (PNs) and GABAergic fast-spiking neurons (FSNs) during spontaneous licking and forelimb movements in male mice. Recordings centered on the face/mouth motor field of the anterolateral motor cortex (ALM) revealed that FSNs fire longer than PNs and earlier for licking, but not for forelimb movements. Computational analysis revealed that FSNs carry vastly more information than PNs about the onset of movement. While PNs differently modulate their discharge during distinct motor acts, most FSNs respond with a stereotyped increase in firing rate. Accordingly, the informational redundancy was greater among FSNs than PNs. Finally, optogenetic silencing of a subset of FSNs reduced spontaneous licking movement. These data suggest that a global rise of inhibition contributes to the initiation and execution of spontaneous motor actions.

SIGNIFICANCE STATEMENTOur study contributes to clarifying the causal role of fast-spiking neurons (FSNs) in driving initiation and execution of specific, spontaneous movements. Within the face/mouth motor field of mice premotor cortex, FSNs fire before pyramidal neurons (PNs) with a specific activation pattern: they reach their peak of activity earlier than PNs during the initiation of licking, but not of forelimb, movements; duration of FSNs activity is also greater and exhibits less selectivity for the movement type, as compared with that of PNs. Accordingly, FSNs appear to carry more redundant information than PNs. Optogenetic silencing of FSNs reduced spontaneous licking movement, suggesting that FSNs contribute to the initiation and execution of specific spontaneous movements, possibly by sculpting response selectivity of nearby PNs.
Metamodal Coupling of Vibrotactile and Auditory Speech Processing Systems through Matched Stimulus Representations

It has been postulated that the brain is organized by “metamodal,” sensory-independent cortical modules capable of performing tasks (e.g., word recognition) in both “standard” and novel sensory modalities. Still, this theory has primarily been tested in sensory-deprived individuals, with mixed evidence in neurotypical subjects, thereby limiting its support as a general principle of brain organization. Critically, current theories of metamodal processing do not specify requirements for successful metamodal processing at the level of neural representations. Specification at this level may be particularly important in neurotypical individuals, where novel sensory modalities must interface with existing representations for the standard sense. Here we hypothesized that effective metamodal engagement of a cortical area requires congruence between stimulus representations in the standard and novel sensory modalities in that region. To test this, we first used fMRI to identify bilateral auditory speech representations. We then trained 20 human participants (12 female) to recognize vibrotactile versions of auditory words using one of two auditory-to-vibrotactile algorithms. The vocoded algorithm attempted to match the encoding scheme of auditory speech while the token-based algorithm did not. Crucially, using fMRI, we found that only in the vocoded group did trained-vibrotactile stimuli recruit speech representations in the superior temporal gyrus and lead to increased coupling between them and somatosensory areas. Our results advance our understanding of brain organization by providing new insight into unlocking the metamodal potential of the brain, thereby benefitting the design of novel sensory substitution devices that aim to tap into existing processing streams in the brain.

SIGNIFICANCE STATEMENTIt has been proposed that the brain is organized by “metamodal,” sensory-independent modules specialized for performing certain tasks. This idea has inspired therapeutic applications, such as sensory substitution devices, for example, enabling blind individuals “to see” by transforming visual input into soundscapes. Yet, other studies have failed to demonstrate metamodal engagement. Here, we tested the hypothesis that metamodal engagement in neurotypical individuals requires matching the encoding schemes between stimuli from the novel and standard sensory modalities. We trained two groups of subjects to recognize words generated by one of two auditory-to-vibrotactile transformations. Critically, only vibrotactile stimuli that were matched to the neural encoding of auditory speech engaged auditory speech areas after training. This suggests that matching encoding schemes is critical to unlocking the brain's metamodal potential.
Just agricultural science: The green revolution, biotechnologies, and marginalized farmers in Africa
Authors: Dowd-Uribe Brian
Published: May 2023

Contemporary agricultural development has changed in significant ways since the green revolution (GR). Its goals have expanded beyond national development to the achievement of environmental and social goals, and, notably, targeted gains for marginalized farmers. Moreover, advances in molecular breeding have expanded the tools used to achieve such goals. This research examines a prominent agricultural biotechnology program, pest resistant (Bt) cowpea in Burkina Faso, and asks whether and how this program can best achieve its goal of delivering benefits for marginalized farmers. I argue that 2 substantially criticized assumptions of GR-era agricultural development—the scale-neutrality of seeds and the sufficiency of expert technical knowledge—continue to guide the Bt cowpea project and limit its ability to deliver benefits for marginalized farmers. The presence of these guiding assumptions can be located in key programmatic decisions that work at a cross purpose to the project’s social goals, notably (a) the choice of parent variety favoring commercial producers, (b) an absence of institutions to extend adoption and benefits, and (c) a lack of meaningful farmer inclusion. This case adds to a body of research that shows that biological innovations alone—what I call “just agricultural science”—are not sufficient to drive socially just outcomes for marginalized farmers without accompanying social innovations.
“A German Artwork for the German People”
Authors: Hughes Lesley
Published: May 2023

The opera Mathis der Maler (1935), based on the sixteenth-century German painter Matthias Grünewald, is Paul Hindemith’s most iconic work. Because of its artist protagonist, scholarship on Mathis has traditionally focused on how Hindemith may have used the figure of Grünewald to express his views on aesthetics, the position of the artist in society, and/or his position under the Nazi regime. Little attention has been paid, however, to the cultural significance of Grünewald as a factor behind Hindemith’s choice of topic. This article examines the reception history of Grünewald from his rediscovery in the late nineteenth century through the interwar period in Germany. Drawing on contemporary periodicals and the scholarly literature, I show how the artist became a symbol of German Kultur in the nationalist context of the Franco-Prussian War and the First World War. This symbolic status arguably attracted Hindemith to Grünewald as an operatic subject at the beginning of the Third Reich. Not only did the topic align with National Socialist rhetoric about promoting German art, it also allowed Hindemith to draw parallels between himself and Grünewald, portraying himself and his work as inherently German. Given Hindemith’s determination to avoid controversy in the first tumultuous months of the Nazi regime, I conclude that Mathis represented an accommodation to the rapidly shifting social and political environment.
