Comparison of Intravenous and Periarticular Administration of Corticosteroids in Total Knee Arthroplasty
Authors: Hatayama Kazuhisa , Terauchi Masanori , Oshima Atsufumi , Kakiage Hibiki , Ikeda Keiko , Higuchi Hiroshi
Published: December 2020

Background:

Corticosteroids are widely used in total knee arthroplasty (TKA) to relieve postoperative pain and prevent postoperative nausea. The aim of this prospective, randomized controlled study was to compare the effects of intravenous and periarticular administration of corticosteroids on pain control, prevention of postoperative nausea, and inflammation and thromboembolism markers following TKA.

Methods:

One hundred patients undergoing TKA were randomly allocated to either the intravenous administration or periarticular injection group. The intravenous administration group received 10 mg dexamethasone 1 hour before and 24 hours after the surgical procedure, as well as a periarticular injection placebo during the procedure. The periarticular injection group received a 40-mg injection of triamcinolone acetonide during the surgical procedure, as well as an intravenous administration placebo 1 hour before and 24 hours after the procedure. Postoperative pain scores at rest and during walking and nausea scores were recorded according to the 0-to-10 Numerical Rating Scale. Interleukin-6 (IL-6), C-reactive protein (CRP), and prothrombin fragment 1.2 (PF1.2) were measured preoperatively and postoperatively.

Results:

Pain scores at rest and during walking 24 hours postoperatively were significantly lower in the periarticular injection group than in the intravenous administration group. Nausea scores showed no significant difference between groups. IL-6 at 24 and 48 hours postoperatively also showed no significant difference between groups. CRP at 24 and 48 hours postoperatively was significantly lower in the intravenous administration group than in the periarticular injection group. In contrast, CRP at 1 week postoperatively was significantly higher in the intravenous administration group than in the periarticular injection group. The mean PF1.2 was significantly lower in the intravenous administration group than in the periarticular injection group at 4 hours postoperatively. Two cases of deep venous thrombosis in each group were detected with use of ultrasonographic examination.

Conclusions:

Periarticular injection of corticosteroids showed a better pain-control effect at 24 hours postoperatively than did intravenous administration, whereas the antiemetic effect was similar between treatments. Although intravenous administration had a better anti-thromboembolic effect than periarticular injection, the incidence of deep venous thrombosis was low in both groups.

Traumatic Posterior Hip Dislocation and Epiphysiolysis in a High School Football Player with Successful Outcome at 4 Years Follow-up
Authors: Nazareth Alexander , Cooper Benjamin , Hollenbeck Steven Matt
Published: December 2020

Case:

We describe a case of posterior hip dislocation in a 13-year-old boy after a contact football injury with attempted closed reduction resulting in complete separation of the epiphysis from the femoral neck metaphysis with associated femoral head fracture and posterior dislocation of the femoral head. Treatment was emergently performed with a greater trochanteric osteotomy, open reduction internal fixation using cannulated screws, and additional small diameter drill holes in the femoral head to promote blood flow. The patient did well postoperatively and at over 4 years follow-up had no evidence of avascular necrosis and returned to full athletics participation.

Conclusion:

Particular attention should be taken when reducing hip dislocations in the adolescent population who may be predisposed to epiphysiolysis. Preservation of periosteal soft-tissue attachments and the use of small diameter drill holes to promote femoral head blood flow may have contributed to the excellent outcome.

Authors: Bernstein Derek T. , Kluemper Chase T. , Kearns Kenneth A.
Published: December 2020

Case:

A 43-year-old man with chronic right shoulder pain and dysfunction due to recurrent anterior instability, irreparable subscapularis tear, and glenohumeral arthritis presented to our practice. After workup and counseling, he was treated with anatomic total shoulder arthroplasty augmented by anterior capsular reconstruction using human acellular dermal allograft. At 15 months postoperatively, his forward elevation, external rotation, and internal rotation were 160, 45, and T12, nearly equal to contralateral values. His glenohumeral joint remained reduced, and no complications were encountered.

Conclusion:

We report the first known anterior capsular reconstruction performed in combination with anatomic shoulder arthroplasty.
Concomitant Dislocation of the Hallucal Interphalangeal Joint and Extra-Articular Dislocation of Its Sesamoid
Authors: Lynch-Wong Matthew , Hashem Feras , Al-Baqali Mohammed , Wong-Chung John
Published: December 2020

Case:

A 22-year-old man sustained closed dislocation of the hallucal interphalangeal joint (HIPJ). Painful limitation of movements persisted 2 months after closed reduction. Magnetic resonance imaging revealed dislocation of the hallucal interphalangeal joint sesamoid (HIPJS) from its intra-articular attachment on the superior surface of the plantar plate to an extra-articular subcutaneous location, plantar and lateral to the flexor hallucis longus tendon. The HIPJS was enucleated through a plantar approach, and the foot remains pain-free 18 months later.

Conclusions:

This case represents an unusual combination of HIPJ dislocation and extra-articular dislocation of its sesamoid. Raised awareness of the HIPJS, its normal anatomical location, and configuration will avoid delayed diagnosis.
The Evolution of the Role of Women in the Family and the Public Sphere (The Case of Domestic Women’s Periodicals of the Late 19th ‒ Early 20th Century )
Authors:   Lobachevsky State University of Nizhny Novgorod, Natalia O. Avtaeva , Vasilisa A. Beynenson ,   Lobachevsky State University of Nizhny Novgorod, Ksenia A. Boldina ,   Lobachevsky State University of Nizhny Novgorod
Published: December 2020

The purpose of the article is to consider the process of transformation of the image of a woman and the dominant family model in the main historical periods in the national female periodicals from the end of the 18th century to the present days. The authors note that the image of a woman in the gender media is changing due to the changes in the global and local agenda, in particular, due to the changes in the position of a woman in the family, the structure of a family, and decreasing of the number of family members. These transformations can also be explained by the change in the state’s requests for the promotion of a certain image, for example, the image of a patriotic woman during the Second World War and a mother woman in the post-war period. Over the course of many historical periods, rubrics devoted to the arrangement of everyday life, the relationship of the sexes, health and beauty, and motherhood remain the traditional rubrics of women’s publications. During more than two hundred years of publications, the image of a woman in them has gone through stages from primordial patriarchal models through a surge of individualization and independence to a moderate combination of the role of the homemaker and the installation of autonomy from men. The article also outlines the main trends in the development of modern women’s online publications, which, on the one hand, have inherited the theme and structure of traditional women’s magazines, and on the other, have the features of blogs. If certain characteristic images of a woman in the press gain or lose relevance, the changes in the family model in women’s media can be considered irreversible: there is no return to the image of a patriarchal multi-generational family. The study was based on the methods of historical review, thematic analysis and content analysis of publications of women’s magazines of various historical periods. Keywords: women’s periodicals, the history of women’s periodicals, the image of a woman in the media, media images, gender identity, family model, women’s online media
Kensur Nawang Nima’s Treatise “The Lamp of Collected Quotations from Classical Works of the Buddhist History”: the Genesis of the Buddhist Monastic System in Northwest China
Authors:   Buryat State University, Andrey A. Bazarov ,   Institute for Mongolian, Buddhist and Tibetan Studies, Siberian Branch, Russian Academy of Sciences, Vladimir V. Khartayev ,   Institute for Mongolian, Buddhist and Tibetan Studies, Siberian Branch, Russian Academy of Sciences
Published: December 2020

The article is devoted to the analysis of the Buddhist monastic history in Northwest China, described in the treatise of the Buryat scholar Kensur Nawang Nima “The lamp of collected quotations from classical works of the Buddhist history”. This work is an example of Buddhist historical thought, which was developed in the traditional culture of the Buryats in the pre-revolutionary period. The authors of the article claim that “The lamp of collected quotations” has a specificity of presentation, determined by the author’s personality, historical and cultural circumstances. This specificity is related to the post-classical period of the history of Tibetan scholasticism, within which the work was written. Buddhist historical thought tried to understand the results of the most important stages of the Buddhist history in the vast region based on the works of previous generations. The treatise can be described as a scholastic work and Nawang Nima as an outstanding scholar and theorist of his time. Analysis of the structure of the work has showed that the author focused primarily on the history of the Geluk School, which he belonged to. Due to this specificity, most of the text is devoted to the biography of the founder of the school Je Tsongkhapa. The volume of work directly related to the history of Buddhist monasteries in northwestern China is extremely small. Nawang Nima describes the Genesis of the Geluk Buddhist monasteries: Chacung (bya khyung), Kumbum (sku ‘bum byams pa gling), Gonlung (dgon lung byams pa gling), Ganden (lga ldan dam chos gling), Rongwo (rong bo dgon chen), Labrang (bla brang bkra shis ‘khyil), Chone (сone dgon chen), etc. This fragment of the work “The lamp of collected quotations from classical works of the Buddhist history” is a fundamental historical description of the most important religious and cultural processes in the territories of Inner Asia in the period from the 19th up to the 20th century. Keywords: Buddhism, history, monastery, Buryatia, Tibet, Northwest China, Nawang Nima
Mongolian Studies in the USSR During the Great Patriotic War of 1941–1945
Authors:   Buryat State University, Oksana N. Polyanskaya
Published: December 2020

The article is devoted to the history of Mongolian studies in the USSR during the Great Patriotic War of 1941–1945. This research is based on the correspondence of the leading Russian specialists in Mongolian studies of the early 20th century N. N. Poppe and V. L. Kotvich, who successfully continued their research work in the 1920s–1940s. The paper makes reference to letters from the Polish Academy of Learning (Krakow) that contain aims of Soviet Mongolian studies, a work plan for 1941 and the scientific results of Mongolian cabinet of the USSR Institute of Oriental studies of the Academy of Sciences in the 1930s. It also focuses on memoirs by Lydia Leonidovna Viktorova published in 2003 as an important source for studying the activities and personal qualities of the Orientalists of the stated period. Lydia Leonidovna was a participant of the Great Patriotic War (an interpreter ‒ 1943–1944), a lecturer of Mongolian Philology Department and the Faculty of Oriental Studies at Leningrad State University (since 1956). She was a student of that faculty during the war (1945–1948) and in the first post-war years (1945–1948). The analysis of the correspondence makes it possible to conclude that the evacuated Institute of Oriental Studies continued its work in Tashkent, focusing mainly on the requirements put forward by the war. Mongolian studies were given renewed momentum in Buryat-Mongolian Research Institute of Language, Literature and History, Buryat-Mongolian Pedagogical Institute in Ulan-Ude, as well as in Irkutsk State University. As a result of evacuation and reorganization of the country’s central universities during the Great Patriotic War, leading orientalists, specialists in history and linguistics came to work in the national republics of the USSR and Siberia. The article reflects the wartime activity of such specialists in Mongolian studies as S. A. Kozin, T. A. Burdukova, K. M. Cheremisov, G. N. Rumyantsev, N. P. Shastina, D. D. Amogolonov, D. A. Abasheev and others. Keywords: Mongolian studies in the USSR, Institute of Oriental Studies of the USSR Academy of Sciences, Leningrad State University, Buryat-Mongolian Pedagogical Institute, Buryat-Mongolian Research Institute of Language, Literature and History, the Great Patriotic War

Authors:   Kerch Polytechnic College, Valery A. Dozmorov
Published: December 2020

The article discusses the views of Russian scientists who studied medieval Western European culture, namely the cultural-historical school in medieval studies at the turn of the 19th‒20th centuries. The relationship between historical science and modernity is an important issue. Only through the disclosure of the diverse influences of modernity on historical science, a genuine understanding of its actual development can be possible. The goal is to create a holistic image of the cultural and historical direction of Russian medieval studies of the early XX century in the context of the era. Demonstration of interaction, interrelation of Russian historiography of the beginning of the XX century with the cultural environment of the Silver Age. The objectives of the study: firstly, to present the main manifestations of the Silver Age culture; secondly, to consider the problems of Western European culture in the works of Russian historians of the early XX century. We used the following methods to achieve the goal: first, a holistic method that allows you to know the phenomenon in the context of the era. In order to understand a certain part (the cultural-historical direction in Russian medieval studies of the beginning of the 20th century ‒ in this case), it is necessary to understand the era as a whole, the cultural environment (culture of the Silver Age), which affects its constituent parts. Further, a historical-comparative method that allows us to present Russian historiography in the beginning of the 20th century against the backdrop of a pan-European context. A genetic method that allows you to determine the relationship between Russian medieval studies of the beginning of the 20th century and the previous tradition, in this case, the development of medieval studies in the second half of the 19th century. Overall, domestic medieval studies of the beginning of the 20th century developed in the traditions of pan-European medieval studies of the same time. Many of the points that, one way or another, are discussed in the writings of historians of this time were found, with some exceptions, reflected in further developments already during the second half of the 20th century. Keywords: culture of the Silver age, Russian medieval studies, Russian philosophy of the XX century, the Renaissance, the situation in Russia
Servants in Russian Zemstvo Hospitals in the Second Half of the XIX – Early XX Centuries
Authors:   Pushkin Leningrad State University, Anastasia E. Zhukova
Published: December 2020

The article studies professional structure and position of the service staff of zemstvo (county) hospitals in post-reform Russia. The relevance of the subject arises from the lack of historical research aimed at studying such a group of employees of zemstvo hospitals as servants. Recognizing the importance of this category of workers for the effective functioning of medical institutions, as well as fragmentary coverage of this topic in Russian historiography, the author sets the goal of studying the zemstvo hospital serving staff in Russia in the 1860s – 1900s. The study is based on a wide range of sources, including financial reports of the hospitals, proceedings of the county sessions, medical congresses. These sources contain information on the material situation, living conditions and activities of the servants. Using the methods of social history and everyday life history, an analysis of the main characteristics of this group of medical institutions staff is carried out. As a result, the professional categories of servants, existing during the period under review were identified: they include nurses, servants/maids, cooks, watchmen, laundresses, stokers, etc. The article characterizes the serving staff of the hospitals. Moreover, the study observes material factors, such as salaries and living conditions of employees, which were one of the most critical problems for both employees and employers. Low salary, lack of acceptable working and living conditions, implementation of a wide range of functions that often go beyond direct duties – all this made the servants’ position in zemstvo hospitals extremely unfavorable. This could not but affect hospitals organization, the quality of patient care and keeping conditions. Contemporaries drew attention to the existing problems by raising these issues at the county meetings and doctors’ congresses, calling for better work and living conditions for the servants. However, no significant changes or improvements were made in the post-reform period. Keywords: servants, service staff, zemstvo hospitals, history of medicine, Russian Empire

Javaneraffen versus Akazienmonokulturen auf Sumatra
Authors: Zahorka Herwig
Published: December 2020

Auf Sumatra wurden in den letzten beiden Jahrzenten viele Nutzholzplantagen für die Zellstoff- und Papierproduktion angelegt. Große Flächen des tropischen Regenwaldes wurden dafür gerodet. Javaneraffen fallen nun in großen Gruppen in Akazienmonokulturen ein, um sich statt von Waldfrüchten von Blättern und Rinde der Akazien zu ernähren. Von Affen geschälte Akazien werden von Pilzen befallen und sterben ab. Da der große Holzbedarf der Konzerne wegen dieser Verluste weniger stark aus Plantagen gedeckt werden kann, besteht die Gefahr, dass vermehrt im Regenwald Holz geschlagen wird.

großen wissenschaftlichen Leistungen von Stefan Vogel (1925–2015) Teil 5a. Öl statt Nektar – die Ölblumen (Allgemeine Aspekte)
Authors: Weber Anton , Gerlach Günter , Dötterl Stefan
Published: December 2020

Nach der Entdeckung der Parfümblumen hat Stefan Vogel einen weiteren neuen Blumentypus erkannt und erforscht: die Ölblumen. Hier wird von den Blüten fettes Öl als Sammelgut angeboten, das in den sogenannten Elaiophoren gebildet wird. Das Öl wird von spezialisierten Bienen (Vertreter mehrerer Gruppen der Apidae-Apinae und zwei Gattungen der Melittidae-Melittinae) mit hochdifferenzierten Sammelstrukturen an den Beinen oder am Hinterleib gesammelt, und, mit Pollen vermischt, als Futter für die Brut verwendet. In reiner Form wird es auch zum Imprägnieren der Brutzellen genutzt. In über 20, teils sehr umfangreichen Publikationen hat Vogel Ölblumen in 10 Familien meist tropisch- und subtropischer Verbreitung nachgewiesen, beschrieben und den Bestäubungsmodus aufgeklärt (eine weitere Familie bzw. Gattung wurde von Simpson & Neff 1981 hinzugefügt). In diesem Beitrag werden allgemeine Aspekte der Ölblumen (Entdeckungs- und Erforschungsgeschichte, Vorkommen bei den Angiospermen, Grundtypen von Elaiophoren, Nutzung des Öls, Öl-Chemie, Überblick über ölsammelnde Bienen), dargelegt. In der nächsten Ausgabe dieser Zeitschrift wird eine Auswahl von Ölblumen näher beschrieben und illustriert.

The purpose of this study was to identify the relationships between transformational leadership dimensions and the dimensions of teacher self-efficacy in Malaysian Chinese Independent High Schools (CIHS) in Malaysia. This study employed a cross-sectional quantitative survey research design. Data were collected from five CIHS in Pulau Pinang. A total of 384 respondents from CIHS were participated in this study. This study used partial least squares structural equation modelling (PLS-SEM) approaches for data analysis. Findings showed that the charisma dimension has significant relationship with each dimensions of teacher self-efficacy: instructional strategies (β = 0.244, p < 0.05), classroom management (β = 0.264, p < 0.05), and student engagement (β = 0.192, p < 0.05). However, dimension of motivation inspiration has no significant relationships with each dimension of teacher self-efficacy: instructional strategies (β = −0.159, p = 0.061), classroom management (β = −0.185, p = 0.066), and student engagement (β = −0.195, p = 0.068). The dimension of individualised consideration has no significant positive relationship with instructional strategic (β = 0.109, p = 0.130). However, individualised consideration has significant positive relationship with classroom management (β = 0.309, p = 0.001) and student engagement (β = 0.336, p < 0.001). The dimension of intellectual motivation has significant positive relationship with instructional strategic (β = 0.225, p = 0.016). In contrast, no significant relationships were found between intellectual motivation and classroom management (β = 0.100, p = 0.162) as well as intellectual motivation and student engagement (β = 0.336, p < 0.001). Transformational leadership contributed 16.1% variance explained on instructional strategies, 15.8% variance explained on classroom management, and 18.1% variance explained on student engagement dimension. Implications and direction for future studies were discussed.

O objetivo deste estudo foi apontar as falhas de gestão do processo em uma indústria de calçados de pequeno porte por meio das técnicas de simulação de eventos discretos (SED) e do mapa do fluxo de valor (MFV) com vistas a eliminar o desperdício e aumentar a produtividade e, assim, aumentar as receitas da empresa. As metodologias foram baseadas em Rother e Shook (2003) para o desenvolvimento do MFV e em Chwif e Medina (2015) para a construção da modelagem e simulação de eventos discretos. As extrações das informações e dados foram realizadas por meio de câmeras de vídeo, observação direta, indireta e entrevistas informais na empresa. Posteriormente, realizou-se a montagem do estado atual do MFV, modelagem e simulação do modelo, seguido da análise de sensibilidade de três cenários e encerrando com o MFV do estado futuro. O resultado dos cenários obtidos permitiu identificar um aumento de 67,57% no volume da produção, uma redução de 51,02% no lead time e uma redução de 23,13% no custo do produto. Ainda houve a homogeneidade no tempo de disponibilidade dos colaboradores e oportunidades de investimentos na empresa por meio da redução dos gastos. Conclui-se, assim, que as técnicas aplicadas na produção auxiliam nas tomadas de decisão tanto para eventos inesperados quanto para o aprimoramento do processo produtivo.

A energia solar pode ser convertida em energia térmica, utilizada no aquecimento de água através de coletores solares, ou em energia elétrica, por meio de sistemas fotovoltaicos. Visto que o chuveiro elétrico representa uma parcela significativa do consumo residencial brasileiro, o uso da energia solar para esta finalidade se justifica pelas suas aplicações. A proposta deste trabalho é analisar a complementaridade entre sistemas fotovoltaicos e sistemas de aquecimento solar de água, em termos técnicos (área disponível) e econômicos (custo de implementação), a fim de suprir a demanda de energia elétrica e de água quente para banho de residências do extremo sul catarinense. Foram analisados quatro sistemas fotovoltaicos (análise amostral) instalados nas cidades de Turvo, Criciúma e Meleiro, com potências nominais entre 1,25 e 4,16 kWp. Os sistemas que originalmente supriam toda a demanda de energia elétrica da unidade consumidora foram redimensionados a fim de excluir a demanda energética do chuveiro elétrico, a qual foi projetada para ser atendida por dois métodos diferentes: exclusivamente por um sistema de aquecimento solar de água ou por um sistema de aquecimento híbrido solar/elétrico. Os sistemas híbridos foram dimensionados conforme a norma ABNT NBR 15569, enquanto os sistemas de aquecimento puramente solar foram simulados através do software System Advisor Model (SAM), assim como o redimensionamento dos sistemas fotovoltaicos. Por fim, verificou-se que há área disponível suficiente na maioria dos casos analisados, porém, nas quatro unidades consumidoras observadas, a complementaridade entre sistemas fotovoltaicos e sistemas de aquecimento solar de água não é economicamente viável, sendo que a integração única do sistema fotovoltaico se apresenta mais oportuna e atrativa.

Published: December 2020

Este artigo apresenta o desenvolvimento da técnica de modulação space vector para um inversor multinível híbrido assimétrico com nove níveis na tensão de fase, com o objetivo de aperfeiçoar as características dos sinais de saída gerados pelo inversor através da seleção dos vetores de comutação. A introdução contextualiza o uso de inversores multiníveis e mostra algumas características das técnicas de modulação que podem ser usadas nesses conversores. A seguir, é exposta a topologia do inversor multinível híbrido assimétrico e, depois, são apresentados os passos necessários para o desenvolvimento da técnica de modulação space vector, determinados como: definição dos estados de chaveamento; definição dos vetores de comutação no plano ?-?; identificação dos planos limites e dos planos de separação; obtenção das matrizes de decomposição; e, finalmente, definição da sequência de comutação. Duas sequências de comutação são escolhidas para obtenção da tensão de saída do inversor, sendo a qualidade do sinal gerado avaliada através de índices de desempenho implementados em software de simulação matemática. A primeira sequência de comutação é obtida realizando uma escolha aleatória dos vetores de comutação, enquanto a segunda sequência é selecionada para melhorar a qualidade do sinal gerado pelo inversor. Como resultado, a tensão de saída do inversor apresentou menor distorção harmônica, menor fator de distorção de primeira ordem e menor tensão de modo comum. Através desta comparação prova-se a importância de uma criteriosa seleção dos vetores de comutação para inversores multiníveis.

Published: December 2020

No presente artigo é proposto o desenvolvimento de algoritmos de filtragem para sistemas lineares discretos no tempo num cenário de fusão de dados. O objetivo foi desenvolver filtros ótimos robustos, onde os sistemas são sujeitos a incertezas paramétricas e podem operar sob diferentes condições de falhas. A abordagem utilizada para o desenvolvimento dos filtros ótimos deste trabalho foi baseada em dois métodos de otimização, a saber: o método dos mínimos quadrados regularizados e o método da função penalidade. As estimativas tipo Kalman e as correspondentes equações de Riccati são obtidas, matematicamente, como uma extensão de resultados já conhecidos na literatura. Em seguida, foram realizadas simulações no Scilab com o objetivo de verificar a possibilidade dos algoritmos apresentados funcionarem quando estão suscetíveis a diversas condições de falhas. A principal contribuição deste trabalho, foi mostrar que é possível obter filtros ótimos, mesmo quando estes apresentam incertezas paramétricas em todos os parâmetros do sistema e, além disso, estão condicionados a diversos modelos de medidas. Mas para tanto, é necessário utilizar uma técnica denominada fusão de dados, esta por sua vez, possibilita obter informações dos modelos de medidas mesmo quando o sistema está sujeito a falhas. Os resultados obtidos demonstram a eficácia da técnica proposta, pois a mesma permite reduzir significativamente as limitações inerentes ao uso de uma única medida.
Predictive Biomarkers and Novel Targets in the Treatment of Metastatic Renal Cell Carcinoma
Authors: Zhang Haibao , Zhu Guodong
Published: December 2020

Renal cell carcinoma (RCC) is one of the most lethal urologic malignancies.
Partial or radical nephrectomy is the major surgical management for localized RCC, however,
almost 30% of patients will develop recurrence and metastasis after surgery. Metastatic
RCC (mRCC) is a disease with a very poor prognosis, and the 5-year survival of
the mRCC is commonly less than 10%. Unfortunately, mRCC is highly resistant to chemo
and radiotherapy. Therefore, mRCC treatment has become a big challenge for researchers
as well as clinicians. RCC is characterized as clear genetic background, especially
with von Hippel-Lindau (VHL) gene loss or mutation in more than 70% of the cases.
Several molecular factors and signaling pathways have been discovered to possess impact
on the progression of RCC, including VHL-HIF-VEGF angiogenesis signaling,
PI3K/AKT/mTOR signaling, epithelial-to-mesenchymal transition-related pathways, and
Wnt/β-catenin pathway, which play crucial roles in the growth, invasiveness, metastasis
and angiogenesis of RCC. Based on the recent studies of these signaling pathways, some
medicines as well as immune check-point inhibitors have been developed, which have
shown potential therapeutic effects for mRCC. Therefore, our current review aims to summarize
the recent progress of the treatment for mRCC, with a special focus on the strategies
to improve the responsiveness of medicines in patients with mRCC.

Background:

The global health emergency due to SARS-CoV-2 causing the COVID-19 pandemic
emphasized the scientific community to intensify their research work for its therapeutic solution. In this study,
Indian traditional spices owing to various medicinal properties were tested in silico for their inhibitory activity
against SARS-CoV-2 proteins. SARS-CoV-2 spike proteins (SP) and main proteases (Mpro) play a significant
role in infection development were considered as potential drug targets.

Methods:

A total of 75 phytochemicals present in traditional Indian spices retrieved from the published literature
and Dr. Duke’s Phytochemical and Ethnobotanical Database, were docked with Mpro (PDB IDs: 6YNQ),
and the SP (PDB IDs: 6LXT and 6YOR).

Results:

Through the screening process, 75 retrieved phytochemicals were docked with spike protein (PDB
IDs: 6LXT and 6YOR) and main protease (PDB ID: 6YNQ) of SARS-CoV-2. Among them, myricetin, a flavonoid
(rank score: 6LXT: -11.72383; 6YOR: -9.87943; 6YNQ: -11.68164) from Allium sativum L and Isovitexin,
an example of flavone (rank score: 6LXT: -12.14922; 6YOR: -10.19443; 6YNQ: -12.60603) from Pimpinella
anisumL were the most potent ligands against SP and Mpro of SARS-CoV-2. Whereas, Astragalin from Crocus
sativus L.; Rutin from Illicium verum, Oxyguttiferone from Garcinia cambogia; Scopolin from Apium
graveolens L, Luteolin from Salvia officinalis, Emodin, Aloe-emodin from Cinnamomum zeylanicium and
Apigenin from Allium sativum L showed better inhibition against Mpro than SP of SARS-CoV-2. The amino acid
residues like SER, LYS, ASP and TYR were found playing important role in protein-ligand interactions via
hydrogen bonding and Vander Waals forces.

Conclusion:

Optimal use of traditional spices in our daily meals may help fight against COVID-19. This study
also paves the path for herbal drug formulation against SARS-CoV-2 after wet lab validation.
