Arbuscular Mycorrhizal Inoculation Enhances Endurance to Severe Heat Stress in Three Horticultural Crops
Authors: Reva Maxym , Cano Custodia , Herrera Miguel-Angel , Bago Alberto
Published: March 2021

Global climate change is increasing temperatures worldwide, which greatly affects all biological relationships. Plant and soil ecosystems are also suffering in this new scenario, especially in semi-arid areas where water resources are limited. Regarding agricultural crops, temperatures that increase dramatically negatively affect fruit production and quality, making it mandatory to find sustainable practices to cope with these new situations. Symbiotic microorganisms in general and arbuscular mycorrhizal fungi in particular have been revealed as promising methods of alleviating stress that are respectful of the environment and soil equilibrium. In this work, we demonstrate the suitability of an ultra-pure, in vitro-issued arbuscular mycorrhizal inoculant for alleviating severe heat stress when applied to three important agricultural crops (tomato: Solanum lycopersicum L.; pepper: Capiscum annuum L.; cucumber: Cucumis sativus L.) under agronomic conditions. Inoculated plants had greatly improved endurance under heat stress because of increased vigor, productivity, and fruit quality. Considering the actual scenario of global climate change, our results shed a light of hope and indicate more sustainable cultivation practices adapted to global change.
Instabilities of quantum critical metals in the limit $N_f\rightarrow0$
Authors: Säterskog Petter
Published: March 2021

We study a model in 2+1 dimensions composed of a Fermi surface of
N_fNf
flavors of fermions coupled to scalar fluctuations near quantum critical
points (QCPs). The N_f\rightarrow0Nf→0
limit allows us to non-perturbatively calculate the long-range behavior
of fermion correlation functions. We use this to calculate charge, spin
and pair susceptibilities near different QCPs at zero and finite
temperatures, with zero and finite order parameter gaps. While
fluctuations smear out the fermionic quasiparticles, we find QCPs where
the overall effect of fluctuations leads to enhanced pairing. We also
find QCPs where the fluctuations induce spin and charge density wave
instabilities for a finite interval of order parameter fluctuation gaps
at T=0T=0.
We restore a subset of the diagrams suppressed in the
N_f\rightarrow0Nf→0
limit, all diagrams with internal fermion loops with at most 2 vertices,
and find that this does not change the long-range behavior of
correlators except right at the QCPs.

Published: March 2021

During 2020, at the level of legislative initiatives, there is an active discussion about the content of education and outreach activities. Due to the «vagueness» of the concepts of «education» and «educational activity» in academic circles, it is difficult to differentiate various kinds of activities that are valuable in broadcasting high-quality and meaningful information to a wide audience. The authors of the article consider the essential features of education in relation to the objectives of non-formal education and the principles set forth in the Model Law of 2002. The purpose of the article is to propose the author's definition of the concepts of «education» and «educational activity», considering the educational and educational potential in the conditions of mediatization of information and communication, leisure and educational environment. The empirical basis of the article is the materials of scientific publications, the content of the Model Law «On educational activities» and the Concept of educational activities presented in «Education for the future». Research results: 1. The authors considered the connection between education and educational activities, carried out their substantive analysis, determined their mission and revealed their mechanisms and principles of organization. 2. The qualitative component of educational activities is considered both at the level of providing the opportunity to carry out worldview, value-orientated, educational functions, and at the level of particular practices. 3. The principles of educational activities are determined.

Psychological factors of student youth‘s responsible behavior.
Authors:   Chernyshevsky Saratov State University (Saratov), Fadeeva Tatyana
Published: March 2021

The article considers the problem of studying the determinants of the types of responsible behavior of young people. It is assumed that there are similarities and differences in the determination of the types of responsible behavior of the youth. The study involved 70 students (average age – 22 years old, SD = 2.19; men – 12%). We used the standardized methods "Questionnaire for the diagnosis of the personal symptom complex of responsibility" (Kocharyan I.A.), "Methods for the study of self-attitude" (Panteleev S.R.), the questionnaire "Determining the level of self-esteem" (Kovalev S.V.), "Social Desirability Scale" (D. Crown, D. Marlowe). We established that the most pronounced types of social behavior of youth are "ethics" and "self-sacrifice". It is shown that the severity of the type of social responsibility is determined by various combinations of psychological characteristics. The most complex regression equation characterizes the type of responsible behavior “Normalizations”. The least pronounced prediction of responsible behavior was revealed in relation to its types: "Fidelity to principle" and "Self-confidence". The results of this study can be useful for further study of the problems of social responsibility, as well as for the development of programs for the formation of youth's social responsibility in educational organizations.
How COVID-19 impacts Vietnam’s banking stocks: An event study method
Authors: Lai Cao Mai Phuong
Published: March 2021

The banking industry is one of the major industries in the Vietnamese stock market, so understanding how the industry index reacts to unusual events such as COVID-19’s impact is very important for the development of the Vietnamese stock market. This study examines the response of the banking sector index to three lockdown/blockage announcements to prevent the COVID-19 epidemic in Vietnam in 2020. Three times of lockdown/blockage: On February 13, 2020, blockade of Son Loi commune, Vinh Phuc province; on March 30, 2020, Vietnam announced the nationwide epidemic of COVID-19 and then nationwide lockdown, and on July 28, 2020, blockade in Da Nang. In the first case, the abnormal returns changed the sign around the notification date indicating that the stock price deviated from its fair value, but accumulating abnormal returns CAR (0;3] and CAR (0; 2] are both positive and statistically significant, which means that investors are more secure when the epidemic area is tightly controlled. The nationwide lockdown was the event that had the strongest impact on the stock price when both AR and CAR were negative and statistically significant before and after the date of the event’s announcement. Nationwide lockdown was the event that had the strongest impact on stock prices as both AR and CAR were negative in the days before and days after the event. This result supports the theory of imperfect substitution. Only AR [2] was positive and statistically significant, showing that the blockade event in Da Nang had a slight impact on the banking sector’s stock price.

Authors: Qiao Lin , Shi Yu , Cheng Qingli , Liu Bingtao , Liu Jing
Published: March 2021

The Fe-Mn oxides composite prepared by a chemical co-precipitation method was used as a heterogenous peroxydisulfate catalyst for the decomposition of aniline. This study investigated the mechanism of aniline degradation by PDS activated with catalyst. Reactive species resulting in the degradation of aniline was investigated via radical quenching experiments with different scavengers, including methanol, tert-butyl alcohol, EDTA and sodium azide. Based on the experiments made here, it is speculated that the predominant reactive species responsible for the degradation of aniline may be holes and singlet molecular oxygen rather than SO4·− and ·OH radicals. The degradation of compounds in catalyst/peroxydisulfate system was put forward. The three possible intermediates were speculated by high performance liquid chromatography-mass spectrometry, and two possible degradation pathways were proposed.
Development of ANN model for discharge prediction and optimal design of sharp-crested triangular plan form weir for maximum discharge using linked ANN–optimization model
Authors: Ayaz Md. , Mansoor Talib
Published: March 2021

Triangular plan form weirs are advantageous over a normal weir in two ways. Within the limited channel width, use of such a weir increases the crest length and hence for a given head, increases the discharge and for a given discharge, reduces the head in comparison with a normal weir. In a previous study, researchers proposed an empirical equation to compute the discharge coefficient of a triangular plan form weir. The prediction error on the discharge coefficient was ±7% from the line of agreement. In the present study, an ANN model has been utilized to train randomly selected 70% data, with 15% tested and validation made for the remaining 15% data. The model predicts the discharge coefficient with a prediction error in the range of ±2.5% from the line of agreement, thereby decreasing the prediction error in Cd by 64%. Also, the sensitivity analysis of the developed ANN model has been performed for all the parameters (weir height, skew weir length and flow depth) involved in the study and the weir height was found to be the most sensitive parameter. Furthermore, the linked ANN–optimization model has been developed to find the optimal values of design parameters of a triangular plan form weir for maximum discharge.

Published: March 2021

Compreender o processo da amamentação além de suas determinações hormonais e fisiológicas e avaliar seu sucesso não somente pelos aspectos meramente técnicos, é um desafio atual. O paradigma da amamentação ainda ancorado em uma visão biologicista precisa ser modificado, pois a amamentação deve ser compreendida não apenas como biologicamente determinada, mas também socioculturalmente condicionada. É indispensável que se construa um novo olhar sobre o Aleitamento Materno, que valorize sua vivência na realidade social, cultural, e econômica da díade mãe e filho. Neste sentido, o presente artigo apresenta o relato de experiência da visita domiciliária como tecnologia de cuidado no incentivo ao aleitamento materno exclusivo para nutrizes de uma Estratégia de Saúde da Família de um município do Sul de Minas Gerais, Brasil. Observou-se que a visita domiciliária contribui para a manutenção do aleitamento materno exclusivo, além de possibilitar que o acadêmico de Enfermagem desenvolva competências para ações assistenciais e educacionais, fato que a torna uma tecnologia de cuidado efetiva.

Clinical Trial Data Sharing for COVID-19–Related Research (Preprint)
Authors: Dron Louis , Dillman Alison , Zoratti Michael J , Haggstrom Jonas , Mills Edward J , Park Jay J H
Published: March 2021

UNSTRUCTURED

This paper aims to provide a perspective on data sharing practices in the context of the COVID-19 pandemic. The scientific community has made several important inroads in the fight against COVID-19, and there are over 2500 clinical trials registered globally. Within the context of the rapidly changing pandemic, we are seeing a large number of trials conducted without results being made available. It is likely that a plethora of trials have stopped early, not for statistical reasons but due to lack of feasibility. Trials stopped early for feasibility are, by definition, statistically underpowered and thereby prone to inconclusive findings. Statistical power is not necessarily linear with the total sample size, and even small reductions in patient numbers or events can have a substantial impact on the research outcomes. Given the profusion of clinical trials investigating identical or similar treatments across different geographical and clinical contexts, one must also consider that the likelihood of a substantial number of false-positive and false-negative trials, emerging with the increasing overall number of trials, adds to public perceptions of uncertainty. This issue is complicated further by the evolving nature of the pandemic, wherein baseline assumptions on control group risk factors used to develop sample size calculations are far more challenging than those in the case of well-documented diseases. The standard answer to these challenges during nonpandemic settings is to assess each trial for statistical power and risk-of-bias and then pool the reported aggregated results using meta-analytic approaches. This solution simply will not suffice for COVID-19. Even with random-effects meta-analysis models, it will be difficult to adjust for the heterogeneity of different trials with aggregated reported data alone, especially given the absence of common data standards and outcome measures. To date, several groups have proposed structures and partnerships for data sharing. As COVID-19 has forced reconsideration of policies, processes, and interests, this is the time to advance scientific cooperation and shift the clinical research enterprise toward a data-sharing culture to maximize our response in the service of public health.
Interpretable prediction for in-hospital adverse stroke events with feature engineering (Preprint)
Authors: Zhang Shuo , Li Runzhi , Wang Nan , Song Bo , Dai Honghua , Xu Yuming
Published: March 2021

BACKGROUND

Stroke is the leading cause of death and disability. And the burden of stroke is rapidly increasing worldwide. In-hospital adverse stroke events prediction help significantly to improve the precise risk stratification and management of patients.

OBJECTIVE

To interpretably predict the in-hospital adverse events in patients with ischemic stroke, we design a novel feature engineering equipped with machine learning methods. It can optimize dataset, select features and eliminate bias. Especially, we further explore the interpretability of prediction model.

METHODS

We use the feature engineering to retrospectively analyze 3-years registered ischemic stroke patient dataset by the process: data preprocessing, feature selection and feature weighting. Then we construct prediction models based on common machine learning methods and analyze the interpretability from the contribution of all features by SHAP (global perspective) and visual analysis of PDP (local perspective) respectively. Among the prediction models, we use multiple candidate predictors including demographic characteristics, medical history, stroke severity, medication history and clinical measurement indicators. The evaluation metrics of the model include: Specificity, Sensitivity, Area Under the Cure(AUC).

RESULTS

The experimental subject is 2310 eligible patients. Feature engineering can effectively optimize dataset, select more valuable features and eliminate statistical and social biases. Finally, we obtain the best experiment performance based on XGB, the AUC of XGB is 0.784 on the original dataset. We also give some experiment results after the feature selection, e.g., the AUC of XGB is 0.747 for dataset selected by the top 15 features, the specificity and the sensitivity is 0.789 and 0.705. The top 4 features, consisting of age, NIHSS score, atrial fibrillation and ability to walk within 48 hours of admission, are sorted according to the SHAP value. We can also clearly observe how these above 4 features affect the prediction results of the model through PDP.

CONCLUSIONS

The designation of feature engineering enables machine learning methods to achieve more better and objective effect considering comprehensive decisions based on specific research conditions. In addition, the exploration of interpretability will extend the application prospect of machine learning methods.
Involvement of End Users in the Development of Serious Games for Health Care Professions Education: Systematic Descriptive Review (Preprint)
Authors: Maheu-Cadotte Marc-André , Dubé Véronique , Cossette Sylvie , Lapierre Alexandra , Fontaine Guillaume , Deschênes Marie-France , Lavoie Patrick
Published: March 2021

BACKGROUND

On the basis of ethical and methodological arguments, numerous calls have been made to increase the involvement of end users in the development of serious games (SGs). Involving end users in the development process is considered a way to give them power and control over educational software that is designed for them. It can also help identify areas for improvement in the design of SGs and improve their efficacy in targeted learning outcomes. However, no recognized guidelines or frameworks exist to guide end users’ involvement in SG development.

OBJECTIVE

The aim of this study is to describe how end users are involved in the development of SGs for health care professions education.

METHODS

We examined the literature presenting the development of 45 SGs that had reached the stage of efficacy evaluation in randomized trials. One author performed data extraction using an ad hoc form based on a design and development framework for SGs. Data were then coded and synthesized on the basis of similarities. The coding scheme was refined iteratively with the involvement of a second author. Results are presented using frequencies and percentages.

RESULTS

End users’ involvement was mentioned in the development of 21 of 45 SGs. The number of end users involved ranged from 12 to 36. End users were often involved in answering specific concerns that arose during the SG design (n=6) or in testing a prototype (n=12). In many cases, researchers solicited input from end users regarding the goals to reach (n=10) or the functional esthetics of the SGs (n=7). Most researchers used self-reported questionnaires (n=7).

CONCLUSIONS

Researchers mentioned end users’ involvement in the development of less than half of the identified SGs, and this involvement was also poorly described. These findings represent significant limitations to evaluating the impact of the involvement of end users on the efficacy of SGs and in making recommendations regarding their involvement.

“Female Rebellion” in Anna Barkova’s Play Nastasya Kostyor (1923)
Authors: Zuseva-Özkan Veronika B.
Published: March 2021

The article examines the figure of the woman warrior and the theme of the “female rebellion” in the hitherto understudied play by Anna Barkova Nastasya Kostyor (1923) in the context of gender studies. Characters, motifs, and the play’s plot are placed against the background of the Barkova’s early work that heavily focused on the “woman question” and invented “new” femininity drawing from the archetypal image of the female warrior in literature and art. The author argues that in this play, Barkova for the first time relates the figure of female warrior to eschatological ideas and utopianism of the Silver Age, namely to Sophia myth. The problem of the ambivalent nature of the female character is in the focus of discussion. The essay explores the sources of this character — from the mystical snake woman of Russian Symbolists to Joan of Arc and the “female ataman” Alena Arzamasskaya (the character of the so-called “Stepan Razin legend”). It describes radical gender inversions in Barkova’s play and explores its original response to the topoi of female warrior that are abundant in this work.
On the Fragmentation in Literature
Authors: Smirnova Natalia N.
Published: March 2021

The aim of this article is to outline the ways to research fragmentation in literature. It raises the following problems, relevant for literary theory: a) each period has different understanding of what is a whole and what is a fragment; b) ideas about the essence and the meaning of fragmentary forms (including the views on increasing / decreasing complexity in literature) are also different; c) the special logic of fragmentation as a technique emerges only in the era of authorship (as opposed to traditionalism), i.e. the individual vision, or the author’s view that destroys the canon. The problem of fragmentation is fundamental for our understanding of the perception and construction of the text, since in different historical periods, the concept of the fragment being contingent on tradition, reread and reinvented in different ways, is in continuous dialogue with its time. The essay concludes that what is considered to be the whole in one historical period turns out to be a fragment in the other, and vice versa.

Audit committee effectiveness characteristics and auditor switches involving industry specialists
Authors: Singhvi Ankita , Feng Nancy Chun
Published: March 2021

The aim of this study is to investigate the association between audit committee effectiveness characteristics and auditor switches to or from an industry specialist audit firm. This study uses data on auditor changes from Audit Analytics, financial data from North American Compustat, and hand-collected data including audit committee characteristics (such as audit committee chair tenure, the proportion of auditing experts on the audit committee, etc.), the number of audit committee meetings and stock ownership from proxy statements between 2005 and 2011. The results reveal that firms with audit committees that have a large proportion of auditing experts are more likely to choose an industry specialist auditor when the firm switches its auditor. Furthermore, the results also show that the longer the tenure of the audit committee chair is, the more likely that the firm switches from a non-specialist to a specialist auditor. This study adds to the literature by exploring the association between audit committee effectiveness characteristics and auditor switches involving industry specialists. The findings inform regulators regarding the impact that audit committee effectiveness characteristics have on auditor switches involving specialists

Histidine protonation states are key in the LigI catalytic reaction mechanism
Authors: ZHAO LINA , Mondal Dibyendu , Li Weifeng , Mu Yuguang , Kaldis Philipp
Published: March 2021

Lignin is one of the world’s most abundant organic polymers, and
2-pyrone-4,6-dicarboxylate lactonase (LigI) catalyzes the hydrolysis of
2-pyrone-4,6-dicarboxylate (PDC) in the degradation of lignin. The pH
has profound effects on enzyme catalysis and therefore we studied this
in the context of LigI. We found that changes of the pH mostly affects
surface residues, while the residues at the active site are more subject
to changes of the surrounding microenvironment. In accordance with this,
a high pH facilitates the deprotonation of the substrate. Detailed free
energy calculations by the empirical valence bond (EVB) approach
revealed that the overall hydrolysis reaction is more likely when the
three active site histidines (His31, His33 and His180) are protonated at
the ɛ site, however, protonation at the δ site may be favored during
specific steps of reaction. Our studies have uncovered the determinant
role of the protonation state of the active site residues His31, His33
and His180 in the hydrolysis of PDC.

Published: March 2021

Leadership has been appeared since human to begin establishing a community in the world and it continuously grows further because of its usefulness. Particularly, the leadership is a pivotal aspect to increase the management process in any organization. However, it still needs to investigate deeply so that it can be understood comprehensively by practitioners and scholars. Consequently, the study is aimed to explore the history, theories, and basic concepts of leadership. Based on the literature review, it was revealed that leadership history can be traced based on its etymology and philosophy even though the topic of leadership had been known from the ancient age. Moreover, some leadership theories that influence its existence are genetic, great man, trait, behaviour, path-goal, contingency, transformational, and skill. Furthermore, leadership can be conceptualized as the leader’s personal ability to influence others (followers) through relationships, interactions, behaviours and credibility to attain the defined goals. Therefore, this study contributes to advance the leadership literature and emphasize its connection to the field of management. Further studies are recommended to investigate how leadership practices can improve the management process in the organization.

Published: March 2021

Abstract- The determinants of bank performance can be grouped into three groups, namely; 1) bank specific factors related to management decisions and policy objectives, 2) industry factors related to industrial structure and market growth, and 3) macroeconomic factors that reflect the economic conditions in which the bank operates. This study analyzes the effect of bank-specific factors and industry factors on banking performance using panel data regression analysis on a sample of 39 Indonesian Commercial Banks during the 2015-2019 period. Bank specific factors consist of bank size, efficiency, and capital adequacy, while the industrial factor in this study is the market structure which includes market concentration and market share. Banking performance is measured by Return on Equity and Net Interest Margin. The results of this study indicate that bank size and efficiency (BOPO) has a negative and significant effect on banking performance. Capital adequacy and market concentration have no effect on banking performance. Meanwhile, the market share variable has a positive and significant effect on banking performance as measured by Net Interest Margin but does not affect banking performance as measured by Return on Equity. Keywords : bank size, efficiency, capital adequacy, market structure, banking performance Abstrak- Determinan kinerja bank dapat dikelompokkan menjadi tiga kelompok yaitu ; 1) faktor spesifik bank yang terkait dengan keputusan manajemen dan tujuan kebijakan, 2) faktor industri yang terkait struktur industri dan pertumbuhan pasar, dan 3) faktor makroekonomi yang mencerminkan keadaan ekonomi dimana bank beroperasi. Penelitian  ini menganalisis pengaruh faktor spesifik bank dan faktor industri terhadap kinerja perbankan dengan menggunakan analisis regresi data panel pada sampel dari 39 Bank Umum Konvensional Indonesia selama periode 2015-2019. Faktor spesifik bank terdiri atas ukuran bank, efisiensi, dan kecukupan modal sedangkan faktor industri dalam penelitian ini adalah struktur pasar yang meliputi konsentrasi pasar dan pangsa pasar. Kinerja perbankan diukur dengan Return on Equity dan Net Interest Margin.

The diversity of freshwater fish in Way Sindalapai River is quite abundant but there has not been much study on the diversity of fish in Way Sindalapai River. This study aims to determine the diversity of freshwater fish species in Way Sindalapai River, Liwa Botanical Garden. The study began with a preliminary survey with a purposive sampling method and sampling was carried out at 3 sampling locations. The tools used in this study include fishing nets (gill nets), fishing rods, scoop, traditional fishing gear (raas), Global Positioning System (GPS), rulers, and cameras. The sampling points include upstream, middle, and downstream areas. The method used in sample identification is by measuring the morphometry of the samples directly at the sampling location which includes total length, standard length, head length, and height, and collection of fish samples photos. Research parameters and data analysis include environmental factors, the diversity index, the evenness index, and the dominance index. The results showed that 170 fishes were found, 8 species, 2 families, and 4 genera. The fish diversity index in the Way Sindalapai river is included in the medium category from the Shanon-Wiener index calculation results, starting from the upstream, middle, downstream, respectively 1.37; 1,34 and 1,22. Evenness index at all locations are included in the low category from the Shannon-Evenness index calculation results, respectively 0.16; 0.14; and 0.12. The dominance index at all locations is included in the low category based on Simpson's dominance index, which has a value of 0.35; 0.32; and 0.28. Based on the conservation status of the IUCN Red List, ichthyofauna in the Way Sindalapai river is 5 species of low risk (least concern) namely Barbodes microps (wader goa), Rasbora bunguranensis (seluang), Barbodes binotatus (wader cakul), Thynnichtys thynnoides (lumoh), Channa striata (bogo). One species that is critically endangered is Rasbora tawarensis (depik), and two species are lacking information (data deficient) namely Rasbora sumatrana (seluang), and Rasbora semilineata (seluang)

Objetivo:   Este artigo tem como objetivo central compreender a evolução intelectual da Identidade Organizacional (IO) e as oportunidades de estudos futuros em estratégia.Método: Usamos as técnicas bibliométricas de citação e cocitação para avaliar a estrutura intelectual que suporta os estudos sobre IO. A partir de uma amostra de 587 artigos disponíveis na base Web of Science, identificamos os 26 artigos referenciados que suportam os trabalhos atuais.Originalidade/Relevância: Passaram-se 35 anos desde o artigo seminal de Albert e Whetten (1985). Os estudos sobre identidade organizacional cresceram significativamente deste então. Pelo reconhecimento da importância do conceito e pela aparente maturidade do campo, é importante revisitar e compreender os trabalhos que têm influenciado os trabalhos atuais sobre identidade organizacional.Resultados:  Os resultados indicaram que a partir do trabalho seminal mencionado, estudos foram influenciados sobre identidade organizacional e mudança estratégica segundo três abordagens: visão socialmente construída; visão do ator social; e visão institucionalista. Além destes estudos também foram influenciados por trabalhos relacionados às práticas e processos na identificação organizacional.Contribuições teóricas: O estudo permitiu compreender a estrutura intelectual dos estudos em identidade organizacional, proporcionando a indicação de pesquisa futura.

A histopathological analysis of 13 apocrine gland tumors and 22 sebaceous gland tumors in dogs was performed, which were submitted to the Department of Veterinary Pathology from 1 January 2010 to 31 December 2012. An association between the immunohistochemical expression of E-cadherin and Ki-67, the type, and the biological behavior of the tumors was investigated. The mean age of dogs with apocrine gland tumors was 10.15 years, and 10.91 years for sebaceous gland tumors. According to the histopathological analysis, 53.8% carcinomas and 46.2% adenomas of the apocrine glands were found. In the sebaceous gland tumors, epitheliomas were dominant (50.0%), followed by adenomas (36.4%) and carcinomas (13.6%). Survival time in dogs with sebaceous gland tumors was shortest in patients with diagnosed epitheliomas, intermediate in adenomas, and longest in carcinomas. The incidence of metastases was low in the groups with sebaceous adenomas and epitheliomas, and recurrence was most common in carcinomas. The average survival time was about the same for apocrine gland adenomas and carcinomas, with a higher incidence of metastases and recurrence for carcinomas. Immunohistochemical analysis of E-cadherin and Ki-67 expression confirmed the efficiency of this method for the accurate histological classification of apocrine and especially sebaceous gland tumors. The analyzes performed showed that the location and intensity of E-cadherin expression can be helpful in predicting the biological behavior of sebaceous gland tumors. In contrast to sebaceous gland tumors, the analysis of apocrine gland tumors showed that there was no correlation between E-cadherin expression and the biological behavior of apocrine gland tumors.

The effect of Theranekron® on rat ovaries was evaluated in healthy and ischemia-reperfusion injury models. The rats were divided into four groups: group 1: control, group 2: Theranekron® (single dose of 0.3 mg/kg intraperitoneally), group 3: torsion + detorsion, and group 4: torsion + detorsion + Theranekron® (single dose 0,3 mg/kg, intraperitoneally). The ovaries were homogenized by sonication before the analysis and supernatant glucose-6-phosphate dehydrogenase activity, reduced nicotinamide adenine dinucleotide phosphate, reduced glutathione and total protein levels were evaluated spectrophotometrically. Ovary tissues were histologically examined. In group 2, glucose-6-phosphate dehydrogenase activity was significantly reduced (P<0.01) compared to the control group and an increased number of atretic follicles, and hyperaemic and haemorrhagic regions were seen histologically; in group 3, although glucose-6-phosphate dehydrogenase activity was not changed, intense hyperaemia and hemorrhage was observed in the veins of the medulla region and in the cortex. Group 4 showed a decrease in glucose-6-phosphate dehydrogenase activity compared to the control group (P<0.01). Histologically, when compared to group 3, group 4 showed fewer atretic follicles and decreased hyperaemia and hemorrhage in the ovaries, excluding the medulla region. There were no significant differences regarding reduced glutathione and reduced nicotinamide adenine dinucleotide phosphate levels between the groups. The Theranekron® dose applied had some negative effects, such as reduced glucose-6-phosphate dehydrogenase activity, an increased number of atretic follicles, and hyperemia in the corpus luteum and medulla region in intact rat ovaries. Although it reduced glucose-6-phosphate dehydrogenase activity, Theranekron® may have had slight remedial effects on rat ovaries with ischemia-reperfusion injury.
