Structure of Agency Formation Stages in Students: Consistency, Integrity, Formalization
Authors: Panov V.I. , Kaptsov A.V.
Published: September 2021

The article proposes a parallel-sequential formalized scheme for describing an ecopsychological model of agency formation through learning actions of students that includes seven stages. We were able to formulate mathematically based coefficients of consistency and integrity of the stages of agency formation in accordance with this model. It is empirically shown that in the samples of students (of universities: N1=79; M1=19.6; SD1=2.4, all females; of secondary vocational schools: N2=47; M2=16.6; SD2=0.68; all males; of schools, 9th grade: N3=45; M3=15.2; SD3=0.42, males — 43%; 11th grade: N4=52; M4=16.9; SD4=0.38, males — 38%) the model of the agency formation stages is described by a two- factor structure, depending on the motives and the objectives of learning activity. The composition of the factors of the agency formation stages is determined by the orientation on the perspective goals of learning activity which consist of the stages ‘Critic’, ‘Master’ and ‘Creator’, as well as on the current actual goals that includ the stages ‘Observer’, ‘Apprentice’ and ‘Student’.

Published: September 2021

Com este trabalho objetivou-se tratar o lodo de laticínios por meio da compostagem, utilizando a combinação de recursos naturais disponíveis na própria empresa, no que se refere aos parâmetros temperatura, pH, umidade, relação C/N e volume e peso. Foram avaliados sete tratamentos constituídos por lodo de laticínio puro e misturas de lodo com demais resíduos (esterco bovino, podas de grama e cinzas de caldeiras). Para isso, utilizou-se o delineamento inteiramente casualizado, com sete tratamentos e três repetições. Ao longo de 123 dias de avaliação, a variação na temperatura nos compostos permaneceu apenas na fase mesofílica. Ao final do monitoramento os valores de Ph foram de 5,14; 7,16; 9,60; 7,54; 9,96; 10,06 e 9,91 para os tratamentos T1, T2, T3, T4, T5, T6 e T7, respectivamente. Em relação à umidade dos tratamentos, com exceção do T1, os tratamentos avaliados apresentaram valores próximos aqueles considerados adequados à compostagem. Por sua vez, o T4 obteve uma relação C/N melhor que os demais tratamentos (7,75). Entre os compostos finais, verificou-se que nos tratamentos 1 e 4 ocorreram maiores reduções de volume (62% e 58,18%) e de peso (52,45% e 51,33%) respectivamente. Conclui-se que dos compostos produzidos com lodo de laticínios e suas combinações, tem-se o T4, responsável pelos melhores resultados, quanto a reduções de peso e volume, pH, teor de umidade e relação C/N. Recomenda-se a adição de grama ao lodo de laticínios como a técnica mais indicada para redução e adequação destes parâmetros.

Published: September 2021

A maioria dos solos brasileiros possui baixa fertilidade natural. A principal característica é a deficiência de fósforo (P) e alta capacidade de adsorção de P. Isso gera a necessidade de adicionar fertilizantes minerais fosfatados, orgânicos ou organomineral. Essa adição pode causar alterações na dinâmica do P no solo. Assim, o objetivo deste estudo foi avaliar as frações P no solo em função da aplicação de fertilizante orgânico, organomineral e fosfato mineral, em diferentes classes de solo. O delineamento experimental utilizado foi o inteiramente casualizado, em esquema fatorial 3x3. Os tratamentos consistiram de três fontes de P (fosfato mineral, orgânico e organomineral) em três classes de solo (LATOSSOLO VERMELHO Distrófico, ARGISSOLO AMARELO Distrófico e NEOSSOLO QUARTZARÊNICO), cultivados com Glycine max e depois com Urochloa (sin. Brachiaria) ruziziensis, nas mesmas unidades. Para o fracionamento de P, foi realizada uma coleta de todas as unidades experimentais aos 270 dias após a implantação do experimento. A adubação orgânica com fosfato aumentou o P total do solo, principalmente as formas não lábeis, enquanto a adubação mineral contribuiu para incrementos nas frações lábeis de P nos solos. Em solos arenosos, os níveis lábeis de P são maiores.

Published: September 2021

A competência legal do cirurgião-dentista para prescrever medicamentos está amparada na Lei nº 5.081/1966, que regulamenta o exercício desse profissional no Brasil. Todavia, apesar das normativas, ainda ocorrem erros na prescrição. O objetivo deste estudo foi analisar a qualidade das prescrições odontológicas e a compreensão do paciente em relação ao tratamento farmacológico proposto. Foram utilizados questionários validados para análise das prescrições e verificação da compreensão dos pacientes sobre elas. O percentual de prescrições com grafia legível variou de 94 a 100%. A maior dificuldade dos pacientes foi relatar a indicação das precauções e reações adversas dos medicamentos. Concluiu-se que as prescrições emitidas pelos cirurgiões-dentistas, de maneira geral, apresentaram boa legibilidade, entretanto mostraram inconformidades com a legislação. Grande parcela de pacientes não soube informar com segurança os dados que garantam o uso seguro e eficaz do fármaco.

Objective: To investigate the effect of lip closure on reduction of cleft palates when no pre-surgical infant orthopedics (PSIO) are used. Study design: Retrospective patient chart-review in our department for Cranio-Maxillofacial Surgery at the University Medical Centre Freiburg, Germany. 19 patients at the age of 5.9 ± 2.1 months with surgical treatment of uni- (UCLP), or bilateral cleft lip and palate (BCLP) without any use of PSIO were included. Results: Early soft tissue correction of the lip leads to an effective reduction of the maxillary arch without any use of PSIO. The presented conventional and digital measurements appeared to be reliable. A successful reduction of the cleft width (UCLP = 3.88 ± 2.42mm, BCLP = 7.33 ± 5.00mm), the width of the alveolar arch (1.91 ± 1.36mm) and the sagittal depth of the alveolar arch (3.07 ± 2.71 mm) could be achieved with the presented workflow. Conclusions: Cleft reduction was obtainable without PSIO when lip closure after Tennison-Randall was performed.

Authors: Rahman Bushra , Goswami Mousumi
Published: September 2021

Objective: In a tooth with deep dentinal caries; judicious removal of infected dentin and isolating affected dentin from oral fluids with suitable biocompatible material is called indirect pulp therapy (IPT). This randomized clinical trial was done to evaluate and compare the efficacy of Biodentine, Theracal LC and. Dycal as an indirect pulp capping agent in young permanent teeth. Study Design: IPT was performed in 60 young permanent molars with caries approaching pulp in 55 healthy children using Biodentine, Theracal and Dycal. A 2–3mm layer of GIC was placed over the intervening material followed by restoration of cavity with composite. Clinical and radiographic examinations were conducted at 3 weeks, 3 months, 6 months,12 months, 18 months and 24 months. The data was compared using chi-square test at a significance level of 0.05. Results: By end of 24 months ,54 teeth presented for follow up with overall success rate of 100% in Theracal, 94.44% in Biodentine, and 77.78% in Dycal. Overall success of Theracal was statistically significant in comparison to Biodentine and Dycal at 24 months follow up (p= 0.03)

Conclusions: Radiographic and clinical outcomes of Theracal and Biodentine suggest their use as an alternative material for IPT in young permanent molars with higher success.

Published: September 2021

Objectives: To investigate the effect of Co-curing versus Staged-curing and No-bonding on retention of different resin-based sealants (RBS). Study design: For shear bond strength (SBS) and microleakage tests, 90 extracted premolars were divided equally into 3 groups (I, II, III). Each group was further subdivided equally into 3 subgroups (a, b, c). No-bonding subgroups did not receive a bonding agent, Staged-curing subgroups received a bonding agent that was cured before sealant application, while Co-curing subgroups received a bonding agent that was cured after sealant application. Seal-it was applied for group I, Helioseal-F for group II and Clinpro for group III. SBS buttons were tested using Instron machine, while microleakage specimens were examined using micro-CT. Results: Clinpro showed the highest SBS values in Staged-curing and No-bonding groups (8.72±2.39, 12.51±3.16) respectively. Staged-curing was significantly greater in SBS values than those for other groups (P<0.05). There was a significant difference in microleakage values of Staged-curing among different RBS (P = 0.003), while there was no significant difference in values of No-bonding and Co-curing among different RBS (P = 0.541, P = 0.521). Conclusions: The use of a bonding agent as Staged-curing was more effective in improving sealant retention than No-bonding and Co-curing.

Published: September 2021

Objective: To compare the shear bond strength (SBS) after thermocycling of four universal adhesives applied in self-etch mode on dentin and etch-and-rinse mode on enamel. Study design: Flat 144 buccal or lingual dentin and enamel surfaces from 72 non-carious primary molars were prepared. Samples were segregated into 12 groups (n=12): Adper Single Bond 2 etch-and-rinse (SB_T) and Clearfil SE Bond self-etch (SE_S) applied to enamel and dentin served as controls. Scotch Bond Universal Adhesive (SBU), Clearfil S3 Bond Universal Adhesive (SEU), Tetric N-Bond Universal Adhesive (TEN), and All Bond Universal (BIS) were applied in etch-and-rinse mode to enamel and in self-etch mode to dentin. They were thermocycled for 5000 cycles. SBS testing and the evaluation of fracture mode were performed. Results: SB_T showed statistically higher SBS than other adhesive groups using etch-and-rinse mode on enamel. SE_S and BIS had statistically higher SBS than other adhesive groups using self-etch mode on dentin. Mixed failure was the most common failure mode in each group. Conclusion: The universal adhesives did not show higher SBS than SB_T when using etch-and-rinse on enamel. All universal adhesives showed higher SBS than SB_T and had SBS similar to SE_S, except SBU when using self-etch mode on dentin.

Published: September 2021

Taxation plays an important role in investment decisions and on net profit. In this view, this paper examines the fiscal determinants of investments realized by non-financial corporations in European Union (EU) countries. More exactly, the influences of profit tax and other important taxes like consumption and labor tax on the rate of investment are analysed. For this purpose, we use a panel analysis for 28 Member States from 2008 to 2018. In the presence of variables cointegration, we apply the fully modified ordinary least square (FMOLS) for investigating the long-run impact of taxation. Our results show a negative influence of the profit tax and a positive influence of consumption tax on the investment expansion. In addition, we find that the profit tax rate decreased after 2008 representing one of the most important fiscal measure adopted by the majority of EU Member States in order to stimulate the investment increase. The results are important for the governments, corporate governance of the companies and the investors, in order to understand the efficiency of their decisions to recover after a crisis. Keywords: Corporate tax policy, Rate of investment, Panel data.

Authors:   University of Mostar, Mostar, Bosnia and Herzegovina School of Business, Soldo Sara
Published: September 2021

People obtain more knowledge, information and skills on the job market. Thus, the management of human resources is being more crucial for every organization. The concept of workplace learning is becoming an essential factor for businesses success, especially in the times of crisis. It helps companies to stay competitive on the market and helps them to respond promptly to the challenges caused by rapid changes due to the fourth industry revolution. The concept of “Industry 4.0” represents the fast gains of developed technologies and applications in industries that help with increasing the productivity, but also require the employees to continuously improve and learn in order to be able to integrate with new technological improvements. However, different authors have different definitions of what job satisfaction really is. It is an extensively researched yet a barely understood phenomenon in organizations. Job satisfaction yields to subjective perception of how one feels about work. Thus, various factors, both external and internal, are associated with it. This paper aims to provide the definitions and reviews of active workplace learning measures used in empirical studies in human resource development and most commonly used measures for job satisfaction. The research paper can provide organizations and practitioners with the information on different approaches that can be used to measure and identify employees’ preferences and to help them find a way to satisfy their workers and keep them at their side in this fast-changing work environment. Keywords: workplace learning measurement, job satisfaction measurement, industry 4.0

Increasing awareness about providing the necessary care of oral health is essential for patients with a removable prosthesis. The awareness is less interested in dental disorders, being busier with the systemic ones. Planning prosthetic management should only be done after a thorough evaluation of the underlying systemic conditions because the treatment plan might vary accordingly. Previous studies have demonstrated that many systemic diseases are associated with removable prosthesis (RP) procedures. We aim to discuss the feasibility and outcomes of the removable prosthesis for medically compromised patients, including many conditions as diabetes mellitus, cardiovascular, renal, hematological, pulmonary, gastrointestinal disorders and immunocompromised patients. Taking adequate care of oral hygiene practices is recommended for these patients. In addition, it is necessary to have frequent care, but short follow-up visits to make sure that the modalities are still valid for additional use, and to investigate for potential complications and adverse events. Adequate prophylaxis against some diseases might also be the only convenient solution. Therefore, proper management of the medical condition might be associated with the enhanced success of the modality with favorable outcomes and better quality of life. Making unified protocols to deal with these patients is also suggested to enhance the practice among the different clinical settings.
Progress in Entropy Principle, as Disclosed by Nine Schools of Thermodynamics, and Its Ecological Implication
Authors: Wang Lin-Shu
Published: September 2021

The entropy principle has been commonly considered to be a selection principle. A history/philosophy-of-science analysis of development in thermodynamic thought was carried out based on a historical account of contributions to thermodynamics of nine Schools of thermodynamics plus that of Mayer/Joule (the Mayer-Joule principle), publication of A Treatise of Heat and Energy, development in maximum entropy production principle (MEPP), and process ecology formulated by Ulanowicz. The analysis discloses the dual nature in the entropy principle, as selection principle and causal principle, and that as well in thermodynamics: as equilibrium thermodynamics (Gibbsian thermodynamics) and as “engineering” thermodynamics in a general sense. Entropy-growth-potential (EGP) as the causal agent and the theory of engineering thermodynamics entail the concept of causal necessity, as suggested by Poincare. Recent development of the entropy principle into maximum entropy production principle (MEPP) is then critically analyzed. Special attention is paid to MEPP’s explanatory power of biological orders vs. that of process ecology: whereas MEPP asserts universal approach to physics and biology based on physical necessity and efficient causation, the case for “EGP as the causal agent and process ecology” allows biology to be different from physics by allowing the additional presupposition of causal necessity and efficacious causation.

Published: September 2021

The Mataloko geothermal system in Ngada-Flores Regency, East Nusa Tenggara, is located in three active volcanic mountains (Inerie, Ebulobo, and Inielika). The contribution of high levels of CH4 and exhaust emissions of SO2 due to its utilization as a geothermal power plant (GPP) impacts the environment. This study aims to analyze and spatially model the distribution and impact of SO2 and CH4 gas levels in the Mataloko GPP area. The quantitative descriptive method was used through direct measurement at gas wells and laboratory testing. The results showed a tendency to increase SO2 levels in the MT-4 gas-well with levels of 8.00 ppm exceeding the quality standard, which could disturb the environment in the Mataloko-GPP area. Impact of high SO2 will experience dry sediment because it is not combustible in the air, then it will drop slowly to be absorbed by soil and plants. Droplets of acid gas blown by the wind and left on trees and buildings are even inhaled into the breath. In addition, the advantages of model with surfer 12 software can help identify the distribution of SO2 and SO4 emissions in the generating area.

Published: September 2021

Chicken skin is a source of animal protein hydrolysate, which has a potential as an antioxidant. This study aimed to determine the effect of different concentrations of the enzyme papain on the degree of hydrolysis, antioxidant capacity, percentage of reducing power (%RP) and amino acid composition of chicken skin protein hydrolysate. Hydrolysis was carried out using papain with various concentrations (3%, 4% and 5%, w/w protein substrate) at pH 7 and 50℃ for 6 h. The degree of hydrolysis was determined by spectrophotometry. Antioxidant capacity and %RP was determined by ferric reducing antioxidant power method and expressed in milligram of ascorbic acid equivalent per gram of sample, and amino acid composition were determined using high-performance liquid chromatography. The results showed that variations in papain concentration had a significant effect (P<0.05) on the degree of hydrolysis, antioxidant capacity and %RP of chicken skin hydrolysate. The papain concentration of 4% resulted in the optimum protein hydrolysate with a degree of hydrolysis of 61.68%±0.64%, an antioxidant capacity of 8.72±0.30 mg AA/g sample and a %RP of 54.12%±1.78%. The protein hydrolysates of the treated chicken skin showed a high content of amino acids, namely, glycine, glutamate, proline, arginine and aspartate.

Распространенность болезней органов дыхания у жителей промышленного города
Authors: Величко Л.Г. , Пашков А.Н.
Published: September 2021

В общей структуре заболеваемости среди взрослого и детского населения ведущее место занимает патология органов дыхания. К одной из основных причин, вызывающих поражение бронхолегочного аппарата, относят ухудшение экологического состояния воздушного бассейна. Чаще всего это связано с поступлением во внешнюю среду большого количества химических соединений в виде отходов промышленных предприятий и автотранспорта. В этих зонах отмечается повышенное содержание в воздухе таких загрязнителей, как оксид серы, углерода, диоксид азота и др. Попадая в организм, они вызывают поражение верхних и нижних дыхательных путей. В результате у детей и взрослых формируются различные заболевания органов дыхания (острые и хронические), вплоть до инвалидизации.

Современные кристаллические пьезоэлектрики для других форм использования, в частности резонаторов, фильтров, датчиков, линий задержек в радиолокаторах и др. успехами учѐных значительно расширился. Приводятся кристаллические традиционные и новые пьезоэлектрики и некоторые их характеристики. Отмечается, что в кристаллических пьезоэлектриках, а также в пьезоэлектрических керамиках в молекулах содержатся атомы кислорода. На основе физхимии микромира, разработанных Ф.М. Канаревым, предлагается обоснование появления искры в пьезоэлектриках при ударном воздействии ими или о них за счѐт энергетики космического вакуума. Приводятся данные теории СЭВ (суперэлектромгнитного взаимодействия) для объяснения этого эффекта. Указывается, что закон сохранения энергии абсолютно верен в замкнутой энергетической системе и не может использоваться в открытой энергетической системе.

Bel canto sangonderrigbeginsels met spesiale verwysing na die begrip appoggio – ŉ tweedelige ondersoek in die pedagogiek van Werner Nel (Artikel 1)
Authors: Olivier Antoinette
Published: September 2021

Opsomming Gedurende sy vaste ampstermyn (1974–2010) as sangdosent by die Skool vir Musiek van die Potchefstroomse Universiteit vir Christelike Hoër Onderwys – sedert 2004 bekend as die Noordwes-Universiteit (Potchefstroomkampus) – is Werner Nel verantwoordelik vir die tegniese ontwikkeling wat sangstudente sou benodig om vokale kunsmusiek in die Europese tradisie uit te voer. Hierdie artikel ondersoek die stemtegniese beginsels wat Nel gebruik het om sy studente op te lei, met spesiale verwysing na die sentrale en kennelik moeilike begrip appoggio. Laasgenoemde is ŉ kernbelangrike stemtegniese en -estetiese ideaal van die bel canto sangtegniek en dit word gevolglik in hierdie artikel as vertrekpunt gebruik om Nel se onderrigmetodes, onderrigbeginsels of opvoedkundige benadering rakende effektiewe asemhaling vir esteties bevredigende klankproduksie in oënskou te neem. Die metodes van data-insameling vir hierdie enkele, beskrywende gevallestudie sluit beide ŉ tradisionele en sistematiese literatuuroorsig van die bel canto sangtegniek in, sommige van Nel se handgeskrewe en getikte dokumente, asook semi-gestruktureerde onderhoude met Nel en geselekteerde deelnemers wat by hom gestudeer het en wat huidig professioneel werk as sangers en pedagoë. Abstract During his fixed tenure (1974–2010) as singing lecturer at the School for Music of the Potchefstroom University for Christian Higher Education – known as the North-West University (Potchefstroom campus) since 2004 – Werner Nel was responsible for the technical development that singing students would need to perform vocal art music in the European tradition. This article investigates the voice-technical principles that Nel used to teach his students, with special reference to the fundamental and admittedly difficult concept appoggio. The latter is a voice-technical and aesthetic ideal of core importance for the bel canto singing technique and accordingly it is used in this article as a point of departure to examine Nel’s teaching methods, teaching principles or educational approach concerning effective breathing for aesthetically pleasing sound production. The methods of data collection for this single, descriptive case study includes both a traditional and systematic literature overview of the bel canto singing technique, some of Nel’s handwritten and typed documents, as well as semi-structured interviews with Nel and selected participants who studied with him and who currently work professionally as singers and pedagogues.

Published: September 2021

Inorganic nanoparticles are utilized for therapeutic, diagnostic, or in combination, theranostic purposes. The latter involves simultaneous sensing, imaging, or tracking of drug delivery. Furthermore, these nanoparticles can differ in their morphologies, which affect outcomes such as the effectiveness of hyperthermia, induction, drug loading, circulation time by escaping the body's immune system, imaging modality clarity, and biosensing. However, design of these theranostics is limited by the lack of a method to predict their therapeutic efficacy. Herein, we report a simple and novel computational approach via algebraic and geometric calculations of surface area (SA) to volume (V) ratios (SA:V) which can help predict the efficacy of the inorganic nanoparticles of the investigated morphologies. The approach comprises a coding platform for the program and uses Python 3 on a Windows 10 operating system. Analyses of 29 polyhedral morphologies that inorganic nanoparticles could assume ex silico showed that only particular concave and convex morphologies in this size regime are more productive over the standard sizes as well as a few noted in literature for baseline comparison. Our results provide a method that can aid in predicting the efficacy of inorganic nanoparticles with certain morphology giving rise to their fundamental basis and eventual implementation ex silico.

The Ministry of Health (MOH) in the Kingdom of Saudi Arabia (KSA) established a National School-based Screening Program (NSBSP) for health screening of school-going children. Students from specific grades were systematically screened for several health problems including obesity, visual and auditory problems, dental cavities, scoliosis, and attention-deficit/hyperactivity disorder (ADHD). This cross-sectional study aimed to determine the prevalence of these health problems among primary school students based on secondary data obtained from the NSBSP. We included 444,259 screened school children from the 1st and 4th grades of 50% of the selected schools (both private and public) across the KSA during the academic year 2018-2019. Among them, the most prevalent health problems identified were dental cavities (38.7%), eye refractory errors (10.9%), and overweight and obesity (10.5%); the less prevalent problems included ADHD (2.81%), auditory problems (0.6%), and scoliosis (0.48%). A greater prevalence of most health problems was observed in girls than boys. The NSBSP successfully aided the detection of health conditions with high and low prevalence among primary school students in the KSA, and thus, identification of health problems of specific concern. Implementation of effective school health services for the prevention, early detection, diagnosis, and treatment of these health problems is imperative.

The aim of the work was to update the distribution range of Aedes (Stegomyia) albopictus Skuse in the Americas, review the blood-feeding patterns and compare the minimum infection rate (MIR) of the dengue virus (DENV) between studies of vertical and horizontal transmission. The current dis-tribution of Ae. albopictus encompasses 21 countries in the Americas. Extensive review has been conducted for the blood-feeding patterns of Ae. albopictus. The results suggest that the mosquito is capable of feeding on 16 species of mammals and five species of avian. Humans, dogs, and rats are the most common host. Eight arboviruses with the potential to infect humans and animals have been isolated in Ae. albopictus. In the United States of America (USA), Eastern equine encephalitis virus, Keystone virus, La Crosse Virus, West Nile virus, and Cache Valley virus were isolated in the Asian mosquito. In Brazil, Mexico, Colombia, and Costa Rica, DENV (all serotypes) has been frequently identified in field-caught Ae. albopictus. Overall, the estimated MIR in Ae. albopictus infected with DENV is similar between horizontal (10.95) and vertical transmission (8.28). However, in vertical transmission, there is a difference in the MIR values if the DENV is identified from larvae or adults (males and females emerged from a collection of eggs or larvae). MIR es-timated from larvae is 14.04 and in adults is 4.04. In conclusion, it has to be highlighted that Ae. albopictus is an invasive mosquito with wide phenotypic plasticity to adapt to broad and new areas, it is highly efficient to transmit the DENV horizontally and vertically, it can participate in the inter-endemic transmission of the dengue disease, and it can spread zoonotic arboviruses across forest and urban settings.

Published: September 2021

Background. MRI-detected inflammation around the metacarpophalangeal (MCP-)joints is prevalent in RA and poses a markedly increased risk of RA-development when present in arthralgia patients. Such inflammation is called ‘peritendinitis’, since anatomy literature reports no presence of a tenosynovial sheath at these tendons. However, the presence or absence of a synovial sheath at these extensor tendons has never been studied. Methods. A macroscopy and microscopy study of extensor-tendons at the MCP-joints of two embalmed human hands was performed. Routine histology was performed with Haematoxylin-Eosin staining. Results. We found evidence for the presence of synovial lining around extensor-tendons at MCP-joints. A delimited space surrounding the extensor digitorum tendon was observed, which was lined with an epithelium representing fibroblast-like synoviocytes. Conclusion. Contrast-enhancement around extensor tendons at MCP joints observed on MRI in RA represents tenosynovitis and thus inflammation of synovial tissue. Further studies with larger numbers of specimen are warranted to study anatomic variants. In addition, the molecular composition of the tenosynovium remains to be characterized.

Breast cancer (BC) is the most common type of cancer in both men and women alike, but it is more prevalent in women. Natural compounds that can modulate the oncogenic process can be considered a significant anti-cancer agent for treating BC. These natural compounds are more effective than synthetic drugs, which have profound side effects on the normal cell and resistance to cancer cells. Genistein is a type of dietary phytoestrogen included in the flavonoid group with a similar structure of estrogen that might provide a strong alternative and complementary medicine to existing chemotherapeutics drugs. Several research studies demonstrated that it can target the estrogen receptor (ER), Human epidermal growth factor receptor-2 (HER2), and Breast cancer gene-1 (BRCA-1) in multiple BC cell lines, as well as sensitize cancer cell lines to this compound when used at an optimal inhibitory concentration. Genistein effectively showed anti-cancer activities through apoptosis induction, arresting cell cycle, inhibiting angiogenesis with metastasis, reducing inflammation, mammosphere formation, tumor growth, up-regulating tumor suppressor gene, and downregulating oncogene in suppressing cancer progression in vitro and animal model study. In addition, research studies have also suggested that these phytochemicals synergistically reverse the resistance mechanism of chemotherapeutic drugs, increasing the efficacy of some chemoinformatics drugs. Our review article aims to unbox and validate the molecular pharmacology in breast tissue, cell-specific anti-cancer mechanism with synergistic activity, and possible pharmacokinetic parameters of Genistein as a potential alternative therapeutic option for the treatment of BC.
