The article discusses the main problems of the component method implemented in Eurocode 3 and offers approaches aimed at eliminating the existing shortcomings. The authors investigate the possibility of introducing additional n -linear components that sufficiently accurately describe the behavior of the flange joints for various stages of the stress-strain state of the connection. The key aspects and principles of modeling nodal connections using n -linear components, including the structure of components, methods of their modeling, are determined. The analysis of the performance of the new computational model of the system is carried out, theoretical diagrams of «force-displacement» ( F -δ) of n -linear components and diagrams of «flexing moment-angle of rotation» ( M -φ) for a node with n-linear components are constructed. A numerical experiment on modeling a typical node is carried out and the results obtained are compared with theoretical prerequisites.

Authors:   Saint Petersburg State University of Architecture and Civil Engineering, Kamenev I. V.
Published: November 2023

In this paper, the verification of the mathematical model previously proposed by the author for studying the stress-strain state of multilayer cylindrical panels from CLT is carried out. For this purpose, the calculation results of the author's model of three shells of different geometry made of a different number of layers are compared with the calculation results of such structures obtained in PC «Lira-SAD».Structures fixed along the contour in a hinged and rigid manner were subjected to the action of a small evenly distributed transverse load, with the greatest possible panel deflections of 4 mm. The comparison of the deformed state was carried out by the biggest deflection and the deflection in the center of the shells, as well as by the shape of the deformed state of the structures. At the same time, there was studied the influence of the number of functions in the expansion in the Ritz method on the accuracy of the proposed mathematical model. It is shown that with 16 or more terms in the expansion, the deflection calculation error in comparison with the Lira-SAPR PC does not exceed 10%.

Published: November 2023

Government spending is one of the pillars of fiscal decentralisation which plays an important role in overcoming poverty. However, many empirical studies are still being debated, especially at the regional level. Government spending can contribute to reducing poverty depending on the type of government spending. This study focuses on specific types of government spending that contribute to productivity, such as government spending on infrastructure, health, education, and social assistance. The study aims to analyze the effect of regional government expenditures on infrastructure, education, health, social protection, and economic growth on poverty reduction. The measurements of poverty used in this study include Headcount Index, Poverty Gap Index, and Poverty Severity Index. The data were analyzed using a panel data regression from 2015-2020 through multiple regression models directly and indirectly. The estimation results of the direct effect show that only government spending on health can reduce poverty through its three indicators, while government spending on social protection is ineffective. Government expenditures on infrastructure and education are only significant in reducing the income gap between the poor and the depth of poverty. The indirect effect results in the four government spending types being statistically significant on all poverty indicators through accelerating economic growth. Therefore, economic growth at the regional level is an important variable that strengthens the relationship between government spending and poverty reduction for all poverty indicators in the region. In addition, government spending on social protection is helpful for the poor but needs to optimize its utilization with more precise targets.

Obesity is defined as an increase in total body mass due to excess fat, as measured by the body mass index. Obesity affects metabolism through factors such as insulin resistance, which triggers the development of chronic diseases. Lipid and ApoB/ApoA-I ratios can be considered additional assessments, especially in patients at high risk of cardiovascular diseases such as diabetes. This study aims to determine the relationship between lipid and ApoB/ApoA-I ratios with Homa-IR in in non-diabetes mellitus adult subjects. The method used in this study was a cross-sectional study involving a total of 80 non-diabetic adult subjects, consisting of 38 male and 42 female subjects. The results showed that there were significant differences between the ratios of CHOL/HDL, TG/HDL, ApoB/ApoA-I, and HOMA-IR in non-obese and obese non-DM adult subjects (4.64 ± 2.18 vs 5.23 ± 1.87, p = 0.045; 2.38 ± 1.20 vs. 3.18±1.77, p=0.013;0.58±0.17 vs. 0.66±0.17, p=0.035 and 1.47±0.80 vs. 3.34±4.37, p = 0.000), and there was no significant difference between LDL/HDL (p = 0.117). The correlation test results between the ratios of CHOL/HDL to HOMA-IR, LDL/HDL to HOMA-IR, TG/HDL to HOMA-IR, and ApoB/ApoA-I to HOMA-IR in non-DM adult subjects (p=0.05, r=0.308; p=0.037, r=0.233; p=0.000, r=0.402; p=0.19, r=0.261). This study concluded that there was a significant correlation between lipid and ApoB/ApoA-I ratios with Homa-IR in non-diabetes mellitus adult subjects.

Organisational culture stands as a fundamental prerequisite for the efficacious operation of any given organisation. The primary aim of this study is to discern potential alterations within the dimensions of organisational culture across the pre-COVID-19, contemporary, and favoured paradigms within the realm of public administration. The data set was obtained from a cohort of 1189 officials in the Czech Republic. The Organisational Culture Assessment Instrument (OCAI) was deployed for the purposes of conducting an online survey. The dominance of the clan archetype across all examined time frames has been corroborated. In addition, a statistically significant manifestation of these dimensions has been determined. In relation to pertinent variables, specifically gender, age, tenure, manager gender, and the dimensions typifying organisational culture, no statistically significant correlations have emerged. Respondents have not reported a sense of work-life imbalance in the aftermath of the pandemic. In summary, it is deduced that the pandemic has not exerted a drastic influence on the metamorphosis of organisational culture within the ambit of public administration. This study provides invaluable information on the repercussions of the pandemic within a sphere that, as an intangible constituent, often goes under-recognised. Mastery of the positioning of dimensions across diverse archetypes is of paramount significance for managers, as it can provide guidance in the cultivation of an apt organisational culture.
The tragedy of the time horizon
Authors: Böhme Kai
Published: November 2023

Future-orientated thinking needs to be strengthened in planning and policy making to respond to the challenges posed by ‘presentism’. Despite the inherent uncertainty of the future, effective planning and policy making require the ability to envision potential future developments and implications of today´s decisions. The ’tragedy of the time horizon’ emphasises the detrimental effects of short-term thinking on various domains, including the environment, economic stability, and social equity. It encompasses the multifaceted challenges posed by short-term thinking and the neglect of long-term consequences. To combat this, we must boost our future literacy, i.e. the capacity to imagine, read, and use the future, both at the individual and societal levels. Future literacy is vital for navigating uncertainty, making strategic decisions, embracing innovation, enhancing social resilience, and promoting sustainable development. This requires a collective effort to improve future literacy skills, foster imagination and creativity, and overcome the challenges of ‘the tyranny of now’. Envisioning positive futures is crucial for inspiring hope, collaboration, and informed decision-making,particularly in a rapidly changing world.
Successful use of intravenous and oral levetiracetam in a goat to control refractory seizures secondary to suspected polioencephalomalacia
Authors: Stapley Emma D. , Breuer Ryan M. , Burton Alexandra J.
Published: November 2023

OBJECTIVE

To assess the clinical efficacy and plasma concentrations of levetiracetam in a goat with seizures.

ANIMAL

A 5-month-old doeling.

CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES

The goat was referred because of progressive anorexia and lethargy over 3 days. Clinical signs consisted of weakness, obtundation, opisthotonos, anisocoria, and cortical blindness. Initial evaluation was most consistent with polioencephalomalacia.

TREATMENT AND OUTCOME

Neurologic improvement occurred within 4 hours of thiamine administration, with appetite returning over 12 hours. On day 3 of hospitalization, the goat suffered acute onset repetitive seizures that were incompletely responsive to standard interventions over 3 hours. Administration of IV levetiracetam (60 mg/kg) produced resolution of seizure activity within 20 minutes. Levetiracetam was continued twice daily IV, then PO after day 6. Plasma concentrations were above or within therapeutic ranges (5 to 45 μg/mL) as previously established for other species, following both IV and PO levetiracetam. Oral administration (60 mg/kg, PO, q 12 h) resulted in plasma levetiracetam concentrations of 48.1 μg/mL 2 hours after a dose and 23.4 μg/mL 2 hours prior to the next dose.

CLINICAL RELEVANCE

Levetiracetam is a newer anticonvulsant commonly used in humans and small animals due to its efficacy, cost, and wide safety margin. Its use has not previously been reported in domestic small ruminants. In this case, levetiracetam showed excellent clinical efficacy in the face of refractory seizures, with no apparent side effects. Plasma concentrations during oral administration were at the high end of the therapeutic range, indicating absorption in a nonmonogastric species. Further studies are warranted to determine optimal dosing in small ruminants.

Published: November 2023

The purpose of the study was to evaluate the possibilities of MRI in determining the stage of hemorrhagic stroke (HS) depending on structural and perifocal changes in children.

Materials and methods. The study included 46 patients (including 19 boys and 27 girls) aged from the 29th day of life to 18 years, with a clinical picture of cerebrovascular accident and the presence of HS in the brain substance (BS) during an MRI study. For statistical analysis, patients were divided into two groups: group 1 – patients examined in the first 48 hours from the onset of neurological symptoms (21 people), group 2 – after 48 hours (26 people). Comparison in two groups was carried out according to MR signs: the presence of perifocal cytotoxic edema, the presence of perifocal hemorrhagic impregnation, the presence of a cytoplasmic rim. Intergroup comparisons on a qualitative basis were carried out using Fisher's exact test.

Results. As a result of the study, differential diagnostic criteria for the stages of HS in children were determined by analyzing the MRI semiotics of hematoma in combination with the symptom complex of perifocal changes (CPC) in the form of perifocal cytotoxic edema, perifocal hemorrhagic impregnation and cytoplasmic rim. Statistically significant differences in the frequency of occurrence of signs of perifocal cytotoxic edema and perifocal hemorrhagic impregnation in the groups were found. The presence of perifocal cytotoxic edema was statistically significant (p = 0.027) more common in group 1 (47% (n = 10), 95% CI 26–69) than in group 2 (16% (n = 4), 95% CI 5–36). The presence of perifocal hemorrhagic soaking was statistically significantly (p = 0.003) more common in group 1 (81% (n = 17), 95% CI 57–93) than in group 2 (36% (n = 9), 95% CI 18–57). In addition, a statistically significant (p = 0.005) difference was found in the incidence of CPC, which was observed in group 1 (28% (n = 6), CI 12–52) and was not observed in group 2 (0%, (n = 0), 95% CI 0–17).

Conclusions. The use of T2, T1, FLAIR, SWI and DWI modes (b = 1000) in combination with ADC in the protocol of MRI examination of children is mandatory, and only a comparison of the characteristics of the MR signal from a hematoma in combination with an analysis of perifocal changes allows us to differentiate the stage of hemorrhage. HS in the acute and early subacute stages has a similar MRI semiotics, therefore, it is necessary to assess the complex of perifocal changes, which allows to differentiate these stages, as it is determined in patients examined in the first 48 hours (p < 0.05) and is not observed after two days. SWI analysis makes it possible to differentiate the late subacute stage of hematoma from chronic due to different characteristics of the MR signal, and also allows you to establish the presence of perifocal hemorrhagic impregnation, which contributes to the differential diagnosis of hemorrhage in the early stages of the pathological process.

Authors: Kulumbegov Bidzina , Chikovani Tinatin , Gotua Maia , Kikodze Nino , Magen Eli
Published: November 2023

Background: Endothelin-1 (ET-1) and interleukin-33 (IL-33) can modulate the activation of mast cells and basophils in the pathophysiology of allergic diseases, interplaying with other mediators of “low-grade inflammation.” Objective: To compare
ET-1, IL-33, the neutrophil-lymphocyte ratio (NLR), eosinophil-lymphocyte ratio (ELR), platelet-lymphocyte ratio (PLR), eosinophil-basophil ratio (EBR), systemic immune inflammation index (SII), and system inflammation response index (SIRI) in patients with chronic spontaneous urticaria (CSU)
and are antihistamine sensitive (AHS), antihistamine resistant (AHR), omalizumab sensitive (OmS), and omalizumab resistant (OmR). Methods: A prospective observational study enrolled 68 consecutive patients with CSU diagnosed and managed according to the dermatology section
of the European Academy of Allergology and Clinical Immunology (EAACI), the European Union funded network of excellence, the Global Allergy and Asthma European Network (GA2LEN), the European Dermatology Forum (EDF), and the World Allergy Organization guidelines. Patients with a urticaria control
test score of >12 are considered treatment sensitive, and ≤ 12 are considered resistant. The control group consisted of 20 sex-matched subjects without urticarial diseases. Total immunoglobulin E (IgE), antinuclear antibodies (ANA), thyroid stimulating hormone, antithyroid peroxidase,
mean platelet volume (MPV), NLR, ELR, PLR, EBR, SII, SIRI, ET-1, and IL-33 were measured at the study entry and compared between the study groups. Results: Thirty AHS group, 38 AHR group, and 20 control group patients were included. The AHS, AHR, and control groups did
not differ in demographic parameters, but the CSU groups were characterized by higher indicators of inflammation. In comparison with the AHS group, the AHR group was characterized by higher levels of IL-33 (p = 0.007), ET-1 (p = 0.032), C-reactive protein (p = 0.016), MPV (p = 0.002), and
higher rates of positive ANA (p = 0.019). Of the 38 patients from the AHR group, 30 (79%) were included in the OmS group and 8 (21%) were included in the OmR group. The OmR group was characterized by higher levels of C-reactive protein (p = 0.022), EBR (p < 0.001), higher rates of ANA (p
= 0.004), and lower levels of ET-1 (p = 0.025) than the OmS group. Conclusion: Our study did not confirm NRL, PRL, SII, and SIRI, PLR as the biomarkers of treatment response to antihistamines and/or omalizumab in CSU. Higher blood levels of IL-33 and ET-1 characterize AHR
CSU.
Uncertainty and Sensitivity Study on Lateral Jet Interaction for Hypersonic Missile

Published: November 2023

The demanding working environment of hypersonic missiles imposes high requirements on the reliability and stability of the reaction control system. This work aims to investigate the impact of uncertainties in freestream and jet parameters on the flowfield and aerodynamic performance of a missile with a lateral jet. Initially, the influence of angle of attack and Mach number on aerodynamic characteristics is evaluated. The findings indicate that the lateral jet control effect is enhanced as the Mach number increases. Moreover, the interference force/moment does not vary linearly with the angle of attack, and there are notable differences in the flow characteristics when the jet is on the windward and leeward sides. Subsequently, six parameters are selected as input variables. The uncertainties of the output results are analyzed using a stochastic expansion based on the nonintrusive polynomial chaos method. Sensitivity analysis is performed using Sobol indices to estimate the relative contributions of each parameter to the overall uncertainty. Within the given uncertainty interval, the surface pressure of the missile exhibits significant variation, with a maximum uncertainty of approximately 480%. The uncertainty of the recirculation zone range is 50.14%, while the pitch moment amplification factor has an uncertainty of 52.44%. The freestream Mach number, angle of attack, and jet pressure ratio are identified as key factors affecting the aerodynamic performance, surface pressure coefficient, and jet penetration height. Conversely, the contribution of other parameters can be considered negligible.
Design Optimization of Lambda-Wing Planform and Vortex Generators for Longitudinal Instability Alleviation
Authors: Lee Seonguk , Kim Chongam
Published: November 2023

This paper focuses on optimizing the planform and vortex generators (VGs) to improve longitudinal stability of the lambda-wing aircraft by alleviating pitchup. The optimizations are performed in two stages using a Reynolds-averaged Navier–Stokes (RANS) solver that can accurately capture the vortical flow structure, affecting the pitchup. First, the planform configuration is optimized to minimize the rise in the pitching moment while maintaining aerodynamic and stealth performances. The designed planform delays the pitchup by 4 deg and increases the usable lift by 31% due to the leading-edge vortex (LEV) flow over the outboard wing. Second, the VGs are installed and optimized to reduce the sudden increase in the pitching moment at high angles of attack. The designed VGs partially eliminate the separated flow and recover the LEV on the outboard wing, suppressing the radical change in the pitching moment by 75%. Some quantitative difference in aerodynamic coefficients is observed in unsteady RANS computations, but the vortical flow unsteadiness minimally affects the flow structure, and the stability improvement remains over 80%. Overall, the generation and sustainability of the LEV are critical aerodynamic factors to secure longitudinal stability in designing the lambda-wing aircraft.

The article is devoted to the study of the notion of provisional measures under Article 35 of the Brussels Ibis Regulation.The purpose of the study is to analyse the jurisdictional grounds for the application of provisional measures by courtsof the Member States of the European Union. The authors argue that the Brussels Ibis Regulation establishes a dual-track jurisdictional system for the application of provisional measures in cases where the court is seised of the meritsof the case and when the court is not seised of the merits of the case. The application of both bases for provisionalmeasures is consistent with the principle of lis pendens, and therefore if the court that was the first to hear the first ap-plication for interim relief has priority to apply such measures. The analysis was based on the scientific literature on the peculiarities of the application of provisional measures andcase law of the Court of Justice of the European Union. The following methods were used to write the article: analysis,systematic, and legal interpretation.
Protecting Incapacitated Patients’ Rights and Best Interests
Authors: Avci Ercan
Published: November 2023

Contemporary medical ethics requires providing healthcare services in accordance with the patient’s values, preferences and interests based on the rights to self-determination and privacy. Incapacitated patients utilise these rights through substitute decision-makers in light of the substituted judgement and best interest standards. In this context, the article aims to briefly study informed consent and focus on protecting incapacitated patients’ rights and best interests. The article underscores the importance of promoting the autonomy of every patient as much as possible. However, in the case of the lack of decisional capacity and advance directives, surrogates should decide for incapacitated patients based on patients’ known/documented/expressed wishes/ preferences and best interests. Nevertheless, due to the high possibility of the misinterpretation of patients’ values, preferences and interests by surrogates as well as potential financial and social conflicts between patients and their surrogates, in the event of medical procedures with serious consequences, such as life-sustaining support, surrogates should be requested to provide convincing evidence proving that their decisions are in line with the patient’s values, preferences and interests.

Research has been carried out on the effect of potassium hydroxide catalyst concentration on the yield of coconut oil (Cocos nucifera) transesterification and continued to characterize the reaction results. The concentration of potassium hydroxide used was 1, 2, and 3% by weight of coconut oil with ethanol as the reactant. The data processing used was the one-way analysis of variation and its characterization from a physicochemical perspective, followed by the analysis of gas chromatography-mass spectroscopy (GCSM) and infrared spectrophotometry. Based on the data processing results, potassium hydroxide concentrations of 1, 2, and 3% did not affect the yield of the transesterification reaction of coconut oil, and the results were 74.5264%, 71.9330%, and 69.0420%. The characterization results show that the physicochemical properties of the reaction products, such as acid number, density, and viscosity, comply with the Indonesian National Standard (SNI) for biodiesel. The results of the GCMS analysis showed that nine peaks were dominated by ethyl laurate.
Hemilabile Quinone Ligands Enable Nickel-Catalyzed C−S(Alkyl) Bond Formation in the Carbosulfenylation of Unactivated Alkenes
Authors: Li Zi-Qi , Alturaifi Turki , Joannou Matthew , Liu Peng , Engle Keary
Published: November 2023

A three-component coupling approach towards structurally complex dialkylsulfides is described via the nickel-catalyzed 1,2-carbosulfenylation of unactivated alkenes with organoboron nucleophiles and alkylsulfenamide (N–S) electrophiles. Efficient catalytic turnover is facilitated using a tailored N–S electrophile containing an N-methyl methanesulfonamide leaving group, allowing catalyst loadings as low as 1 mol%. Regioselectivity is controlled by a collection of monodentate, weakly coordinating native directing groups, including sulfonamides, amides, sulfinamides, phosphoramides, and carbamates. Key to the development of this transformation is the identification of quinones as a family of hemilabile and redox-active ligands that tune the steric and electron properties of the metal throughout the catalytic cycle. DFT results show that the duroquinone (DQ) ligand adopts different coordination modes in different elementary steps of the Ni-catalyzed 1,2-carbosulfenylation—binding as an X-type redox-active durosemiquinone radical anion to promote alkene migratory insertion with a less distorted square planar Ni(II) center, while binding as an L-type ligand to promote N–S oxidative addition at a more electron-rich Ni(I) center.

JEAN-PAUL SARTRE AND EXISTENTIAL LIBERTY
Authors: Dũng Nguyễn Tiến
Published: November 2023

These days, numerous Sartre’s existential thoughts are still misunderstood. One of the reasons for this misunderstanding is that many authors have divided his life and thoughts into two parts. To understand the essence of Sartre’s conception of liberty, we cannot fail to clarify the interrelationship of his life and the content of his philosophy.

Ẩn dụ ngữ pháp là một trong những hiện tượng ngôn ngữ được giới thiệu bởi Halliday trong công trình nghiên cứu về ngữ pháp chức năng hệ thống của ông. Bài viết này phân tích ẩn dụ tư tưởng trong các hợp đồng kinh tế tiếng Việt dựa trên lý thuyết ngữ pháp chức năng hệ thống. Mục đích của bài viết là tìm ra các đặc trưng trong ẩn dụ tư tưởng, phương thức thể hiện, các dạng không tương thích (ẩn dụ) và tương thích (không ẩn dụ). Kết quả nghiên cứu cho thấy, ẩn dụ tư tưởng trong hợp đồng được hiện thực hóa thông qua danh hóa cụm động từ và danh hóa cú / mệnh đề. Trong đó, danh hóa cú / mệnh đề chiếm ưu thế hơn rất nhiều so với danh hóa cụm động từ. Danh hóa cụm động từ diễn ra ở hầu hết các quá trình chuyển tác. Trong danh hóa mệnh đề, Cú bị bao được danh hóa, giữ vai trò như cụm danh từ làm Chu cảnh trong các cú quá trình không tương thích chiếm ưu thế nhất trong các kiểu danh hóa cú / mệnh đề.

Quirky Desires and Well-Being
Authors: Bruckner Donald
Published: November 2023

According to a desire-satisfaction theory of well-being, the satisfaction of one’s desires is what promotes one’s well-being. Against this, it is frequently objected that some desires are beyond the pale of well-being relevance, for example: the desire to count blades of grass, the desire to collect dryer lint and the desire to make handwritten copies of War and Peace, to name a few. I argue that the satisfaction of such desires – I call them “quirky” desires – does indeed contribute to a desirer’s well-being, when (and only when) the desirer is able to provide what Anscombe calls a desirability characterization of the object of the desire. One successfully provides such a characterization when one is able to describe the object of desire in such a way as to make comprehensible to others what she sees as positive, worthy of pursuit, in that object. To make the case, I consider common desires such as the desires to take a walk on the beach, drink a beer or listen to music. I argue that, although the well-being relevance of such common desires normally is not questioned, their satisfactions contribute to well-being just in case the same condition is met. I then argue by analogy with common desires that quirky desires are also relevant to well-being just in case that condition is met. After sketching this solution to the problem of quirky desires, I show that this response is better than other responses that have been given by desire theorists. I then develop several aspects of this account in response to objections that can be raised against it. Among these (to name a few) are the objection that my account does not apply to the well-being of infants and other inarticulate persons; the objection that intrinsic desires, such as for pleasure, cannot be given desirability characterizations; and the objection that desirability characterizations must advert to pleasure or to objectively good properties of the object of desire, so that my account reduces either to hedonism or to an objective view of well-being.

The paper was aimed at deter­mination of the quantitative activity of iNOS and Arg1, as well as M1 and M2 phenotype macrophages in women with endometrioid disease to establish their role in the pathogenesis of endometriosis. A prospective study was performed in gynecological units of the medical facilities of Poltava city. 140 women of reproductive age who made up the main group (110 women with endometrioid disease) and the control group (30 women without endometrioid disease) voluntarily participated in the study. All women underwent planned surgical treatment for existing gynecological pathology. Before surgical treatment, women were examined in accordance with the current Orders of the Ministry of Health of Ukraine. The spectrophotometric method was used to determine the enzymatic markers of macrophages (in the endometrium and peritoneal fluid) polarized into M1(iNOS) and M2 (Arg1) phenotypes. The type of macrophages was determined individually in each patient according to the ratios: in iNOS>Arg1, the M1 macrophage type prevailed; in Arg1>iNOS, the M2 macrophage type prevailed. When examining endometrial samplings in women from the main group, the iNOS indicator was by 1.4 times higher compared to women from the control group. The obtained results at the stage of entry into the abdominal cavity showed that mostly women from the main group suffered from the pelvic adhesion, especially stage 3 and stage 4. Among the obtained results, the increased quantitative activity in the peritoneal fluid of both iNOS and Arg1 in women of the main group was significant compared to the control group. When comparing the stages of endometrioid disease to the rates of quantitative activity of macrophage enzyme markers (in peritoneal fluid), it was found that the increase in the stage of the disease (from stage 3 to stage 4) caused an increase in the quantitative activity of Arg1 by 1.9 times and a decrease in the quantitative activity of iNOS by 2.9 times. Therefore, the planning of surgical intervention for women with endometrioid disease should consider a significant percentage of the pelvic adhesive disease, especially at the severe stages. Initiation of the chronic aseptic inflammatory process in endometrioid disease is caused by an increased quantitative activity of iNOS in the endometrium. In the pathogenesis of endometrioid disease, the presence of M2 phenotype macrophages in the peritoneal fluid is important, while the switching of macrophage phenotypes from a pro-inflammatory subpopulation to an anti-inflammatory one is crucial.
