Hybrid Steel and Its Potential for Bearing Applications
Authors: Andersson Jan-Erik , Lindberg Fredrik , Ooi Steve
Published: September 2020

A novel bearing alloy has been designed utilizing the combination of alloy carbides and intermetallic precipitation hardening. The addition of nickel and aluminum to the steel not only increases the hardness via order strengthening with the precipitation of nickel aluminide but is also found to promote synergy precipitation hardening by limiting the precipitation coarsening of chromium (Cr) carbide. The aluminum content in the steel also promotes the formation of the passive layer in the steel that contains 5 wt.% Cr. It is called Hybrid Steel and is commercially produced by Ovako; it is designed to offer long bearing life and to operate at elevated temperatures. Furthermore, it has the potential to be used in corrosive and hydrogen environments.
Generation of Sharp Wave-Ripple Events by Disinhibition

Published: September 2020

Sharp wave-ripple complexes (SWRs) are hippocampal network phenomena involved in memory consolidation. To date, the mechanisms underlying their occurrence remain obscure. Here, we show how the interactions between pyramidal cells, parvalbumin-positive (PV+) basket cells, and an unidentified class of anti-SWR interneurons can contribute to the initiation and termination of SWRs. Using a biophysically constrained model of a network of spiking neurons and a rate-model approximation, we demonstrate that SWRs emerge as a result of the competition between two interneuron populations and the resulting disinhibition of pyramidal cells. Our models explain how the activation of pyramidal cells or PV+cells can trigger SWRs, as shownin vitro, and suggests that PV+cell-mediated short-term synaptic depression influences the experimentally reported dynamics of SWR events. Furthermore, we predict that the silencing of anti-SWR interneurons can trigger SWRs. These results broaden our understanding of the microcircuits supporting the generation of memory-related network dynamics.

SIGNIFICANCE STATEMENTThe hippocampus is a part of the mammalian brain that is crucial for episodic memories. During periods of sleep and inactive waking, the extracellular activity of the hippocampus is dominated by sharp wave-ripple events (SWRs), which have been shown to be important for memory consolidation. The mechanisms regulating the emergence of these events are still unclear. We developed a computational model to study the emergence of SWRs and to explain the roles of different cell types in regulating them. The model accounts for several previously unexplained features of SWRs and thus advances the understanding of memory-related dynamics.

—We have estimated the P–T conditions of formation of basaltoid melts: P = 1.15–1.06 GPa and T = 1379–1293 ºC. Olivine pyroxenites (Ol + Cpx + Grt) are assumed to be a mantle source for nepheline-normative basanitic melts. During ascent, the melt trapped mantle xenoliths, which were disintegrated into olivine and augite xenocrysts. A decrease in pressure and temperature led to the crystallization of highly magnesian (Mg# = 86) olivine and diopside and Timgt + Ilm ± Pl phenocrysts. Then, the Ol + Cpx + Timgt + Pl microlite paragenesis formed. Alkaline aluminosilicates (acid plagioclase + nepheline + leucite) were the last to crystallize in the rock interstices. The presence of residual glass indicates that the last stage of crystallization took place under subsurface conditions. The volcanic area of southern Transbaikalia (Khentei Ridge) resulted, most likely, from the mantle plume impact on the lithosphere. The age of this area is estimated at 3.51 Ma. PREMA was the main mantle source for these volcanics, and the contribution of HIMU was strongly subordinate. In geochemical features the studied volcanics correspond to mafic rocks of oceanic islands. They are similar in composition to alkali basalts of the South Baikal volcanic area.

—We present results of petrographic, geochemical, and mineralogical studies of apogranite metasomatites associated with sulfide–quartz gold ore veins. The studies show a predominance of muscovite and quartz–muscovite metasomatites. Formation of muscovite metasomatites was accompanied by the accumulation of W, Sc, Zr, Hf, Ga, REE, U, Th, Ta, and Nb and the genesis of new accessory minerals: monazite-(Ce), apatite, zircon, scheelite, W-containing rutile, uraninite, thorianite, cassiterite, etc. Compared with the primary granites, quartz–muscovite metasomatites are richer in Pb, Bi, As, Sb, Co, Ni, Ba, In, Cd, Mo, Te, Ag, and Au (elements of the gold ore assemblage). The high contents of these trace elements are due to abundant galena, fahlores, chalcopyrite, and pyrite among the accessory minerals. Metasomatism of granites was followed by the removal of SiO2, which was then spent for the formation of quartz veins. We have revealed that the distribution of metasomatites of different types within a dike body affects directly the distribution of sulfide–quartz veins and thus determines the ore content of the dike body fragments.

Published: September 2020

—A combination of modern analytical methods was used to study terrestrial organic matter from upper Paleozoic rocks in the central part of the Vulyui hemisyneclise (East Siberia) sampled from the depth interval 3370–6458 m penetrated in the Srednevilyuiskaya-27 superdeep well. In this study, we used 71 core samples to trace depth variations in the geochemical characteristics of organicmatter during middle–late mesocatagenesis and apocatagenesis: organic carbon content (Corg), Rock-Eval pyrolysis parameters (HI, Тmax), carbon isotope composition, thermal maturity (RVto, %), hydrocarbon type composition (hydrocarbons, resins, and asphaltenes), distributions of n-alkanes (TIC), steranes (m/z 217), and terpanes (m/z 191), and standard biomarker indices with increasing degree of thermal maturity. It is shown that during late mesocatagenesis and apocatagenesis, the pyrolysis parameters and biomarker indicators are no longer effective as indicators of organic-matter maturity and genesis.
Cholangiopancreatoscopy: Expanding the Diagnostic Indications of Endoscopic Retrograde Cholangiopancreatography
Authors: Pereira Pedro , Costa-Moreira Pedro , Macedo Guilherme
Published: September 2020

Besides the adverse effects associated with endoscopic retrograde cholangiopancreatography (ERCP), indirect visualization of the biliopancreatic system through fluoroscopy has limited its diagnostic and therapeutic efficacy. Direct visualization through cholangiopancreatoscopy may overcome this limitation and allow the resolution of many dilemmas related to the diagnostic and therapeutic drawbacks of ERCP. Herein, we discuss the current indications of single-operator cholangioscopy (SOC) concerning the diagnostic interventions within the biliopancreatic system. The current role of SOC in the diagnosis of pancreatobiliary stenosis, primary sclerosing cholangitis, intraductal papillary mucinous neoplasm, and pre-surgical mapping of neoplastic lesions were reviewed. There is growing data in the literature supporting the early implementation of SOC in the diagnostic algorithm of pancreatobiliary diseases. In selected cases, this could prevent diagnostic delay and reduce the risks and costs related to repeated ERCPs. This potential characterizes SOC as safety and cost-effective.

Background and Aims: The prevalence of Helicobacter pylori (H. pylori) infection is higher in developing countries and is often linked to lower socioeconomic status. Few studies have investigated the association between H. pylori and individual level characteristics in Europe, where several countries have a high prevalence of H. pylori infection. The study aimed to identify risk factors for H. pylori infection among adults in a large clinical trial in Latvia.

Methods: 1,855 participants (40-64 years) of the “Multicenter randomized study of H. pylori eradication and pepsinogen testing for prevention of gastric cancer mortality” (GISTAR study) in Latvia tested for H. pylori IgG antibodies were included in a cross-sectional analysis. Sociodemographic, lifestyle and medical factors were compared for participants seropositive (H. pylori+) and seronegative. Mutually adjusted odds ratios (OR) were calculated for H. pylori+ and factors significant in univariate analysis (education, smoking, binge drinking, several dietary habits, history of H. pylori eradication and disease), adjusting for age, gender and income.

Results: Of the participants 1,044 (55.4%) were H. pylori seropositive. The infection was associated with current (OR: 1.34, 95%CI: 1.01-1.78) and former (OR: 1.38; 95%CI: 1.03-1.85) smoking, binge drinking (OR: 1.35; 95%CI: 1.03-1.78), having ≥200g dairy daily (OR: 1.37; 95%CI: 1.11-1.69), and very hot food/drinks (OR: 1.32; 95%CI: 1.03-1.69) and inversely with ≥400g vegetables/fruit daily (OR: 0.76; 95%CI: 0.60-0.96), history of H. pylori eradication (OR: 0.57; 95%CI: 0.39-0.84), peptic ulcer (OR: 0.55; 95%CI: 0.38-0.80) and cardiovascular disease (OR: 0.78; 95%CI: 0.61-0.99).

Conclusions: After mutual adjustment, H. pylori seropositivity was associated with lifestyle and in particular dietary factors rather than socioeconomic indicators in contrast to the majority of other studies.

Published: September 2020

Desde março de 2020, quando a Organização Mundial de Saúde declarou que o mundo vivia uma pandemia de COVID-19, acompanhamos um quadro sanitário sem precedentes nos últimos 100 anos. As medidas atuais contra a doença objetivam o controle da transmissão e envolvem ações individuais e sociais de higiene e distanciamento físico, enquanto a busca poruma vacina se mostra como a esperança para vencer a pandemia. Considerando o contexto social de clamor por uma nova vacina, este ensaio crítico discute o paradoxo e as contradições da relação indivíduo-sociedade no contexto da COVID-19, à luz da hesitação vacinal como fenômeno histórico e socialmente situado. Este ensaio aponta que as tomadas de decisão sobre(não) vacinar ou sobre (não) seguir as medidas preventivas e de controle da propagação da COVID-19 são conformadas por pertencimentos sociais e atravessadas por desigualdades que tendem a se exacerbar. A infodemia que cerca a COVID-19 e a hesitação vacinal reflete a tensão entre o risco cientificamente validado e o risco percebido subjetivamente, influenciado pelacrise de confiança na ciência. Percepções de risco e adesão a medidas de saúde extrapolam aspectos subjetivos e racionais e refletem valores e crenças conformados pelas dimensões política, econômica e sociocultural.

Incorporation of betel leaf extract (BE) into chitosan and chitosan/vanillin (CH/Vn) blend films was carried out in order to improve the mechanical, thermal and antimicrobial properties of chitosan films. The influence of morphology, crystallinity and glass transition temperature (T g) on the mechanical properties of chitosan/betel leaf extract (CH/BE) and chitosan/vanillin/betel leaf extract (CH/Vn/BE) films was analyzed. The smooth homogeneous morphology, decreased crystallinity and shift of T g to a higher value resulted in improved mechanical properties. Scanning electron microscopy, atomic force microscopy, X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis and Fourier transform infrared studies indicated that inclusion of BE into CH/Vn led to enhanced physicochemical properties. The results of antimicrobial activity, oxygen gas permeability and contact angle measurements confirmed the significantly improved activity and hydrophilic nature of the blend films compared with those of pure chitosan. The authors confirmed that the plant-extract-doped polymer material can be a novel antimicrobial agent for food-packaging application. Addition of BE at a higher weight percentage is a major limitation that has a major influence on the properties of the blend films.
E-Resources Usage Fosters Self-Learning among the Engineering Student Community
Authors: Prafulla Andhe , Chowdappa N.
Published: September 2020

This paper presents a brief analysis of the engineering college students' e-resource usage needs vis-a-vis habits. The research analysis led to many outcomes and one of them is about the e-resource usage being a dominant factor in the particular engineering student community's self-learning process. Self-learning is attributed to be the major contribution to the academic and professional growth of a person at any point of time. The use of e-resources in and out on day to day basis is forcing the student to become self reliant and helps him to learn how to self-learn many a thing. This self-learning aspect in a student is very encouraging as waiting for an expert to actually teach them everything is time-consuming and next to impossible in this era of many student - single teacher ratio. The information spewing every second from various corners of the globe makes it necessary for each and every student to master the art of self-learning to stay abreast with the happenings in his area of study or interest. This forceful need for information search using e-resources is gradually becoming a necessity and ultimately a habit.

Published: September 2020

The aim of this study is to investigate the experimental abstraction processes of 7th grade students in relation to the variables of attitude, anxiety, self-efficacy and motivation towards mathematics. This is a mixed method correlational study using a sequential explanatory design with two distinct stages. The study group consist of 91 students attending public schools in Ordu city center who were selected by using criterion sampling technique. The data collection tools used in the study are Abstraction Test (AT) which was developed by the researchers and consisting of 8 open ended, gap filling and multiple choice questions, Clinical Interview Processes conducted with the students, Mathematics Attitude Scale developed by Duatepe and Çilesiz (1999), Math Anxiety Scale developed by Erol (1989), Mathematical Self-Efficacy Scale developed by Umay (2001) and Mathematics Motivation Scale developed by Githua and Mwangi (2003)- adapted to Turkish by Ayan (2014). In the analysis of the qualitative data obtained from the study, Action Sequence formed by the researchers and the Clinical Interviews conducted with students were used while Pearson-Correlation analysis techniques were used for the analysis of the quantitative data of the study. As a result of the study, it was seen that students generally do not perform well in the process of knowledge construction and they have misconceptions about the concept of slope. In addition, a significant positive relationship was found between students' knowledge construction processes and attitude-self-efficacy scores towards mathematics, while a significant negative relationship was found between knowledge construction processes and anxiety levels. In the light of the results obtained from the study, some suggestions were made for the literature and teaching environments.

Hasan Ferit Alnar’ın Kanun Konçertosu’nda yer alan müzikal ve teknik zorluklar, stratejik çalışmalarla kolaylaştırılabilir. Bu araştırmada, Hasan Ferit Alnar’ın Kanun Konçertosu’nda yer alan bazı pasajlardaki müzikal ve teknik zorluklara ilişkin stratejik çalışma önerilerine yer vererek, kanunilere Kanun Konçertosu’nu çalışırken öğrenme ve icra etme kolaylığı sağlamak amaçlanmaktadır. Bu bağlamda, araştırmacı tarafından daha önce icra edilen Kanun Konçertosu’nda kanunilerin çalışırken zorlanabileceği pasajlar belirlenmiştir. Belirlenen pasajların çalışılmasına yönelik metin kenarına not alma, gruplama ve örgütleme stratejilerinden melodik örgütleme ve armonik örgütleme stratejileri seçilmiş ve örneklendirilmiştir. Bu araştırma, teorik boyutta bir özel durum çalışması olarak nitelendirilebilir. Alnar’ın Kanun Konçertosu’nun günümüze kadar az sayıda kanuni tarafından icra edildiği söylenebilir. Bu durumun eserin icra zorluğundan kaynaklandığı düşüncesiyle verilen stratejik çalışma önerilerinin Kanun Konçertosu’nu icra edecek kanunilere eserin çalışılmasında kolaylık sağlayacağı ve kanunileri eseri icra etmeye teşvik edeceği düşünülmektedir. Bununla birlikte stratejik çalışma yoluyla Hasan Ferit Alnar’ın Kanun Konçertosu’nu icra edecek kanunilerin sayısının artacağı umulmaktadır. Literatürde kanun alanında bir eserin çalışılmasında stratejik çalışma önerilerine ilişkin bir çalışmaya rastlanılmamıştır. Bu yönüyle de araştırmanın, kanunilere farklı bakış açılarını sunması açısından alana katkı sağlayacağı düşünülmektedir.
Safe Place

Published: September 2020

Interprofessional collaborative practice (ICP) is an essential skill in today’s healthcare environment that can be cultivated through interprofessional education (IPE) in higher education, as students are in the process of developing their professional identities. Undergraduate social work field students and nursing students in clinical rotation explored their experiences together in clinical supervision groups co-led by instructors from both fields. Researchers used a mixed methods approach to measure changes in feelings and skills related to ICP among students who participated in clinical supervision groups. Eighteen nursing and social work students participated; those involved in the interprofessional clinical supervision groups performed better on the Inter-professional Socialization and Valuing Scale (ISVS) than the comparison group. Qualitative themes indicated that students enhanced their interprofessional knowledge; improved their interprofessional communication skills; and increased their comfort levels on an interprofessional team. Implications and suggestions for implementation are discussed.
It’s Time to Go!

Published: September 2020

Interprofessional education provides an opportunity for allied health professions to gain knowledge of health care team roles, and how discrete disciplines collaborate to contribute to a healthcare team. This interprofessional activity used simulation scenarios with simulated patient actors to introduce students in three healthcare disciplines to the communication and collaboration skills used by teams for hospital discharge planning and follow-up care in a home setting. Participation in the simulations was voluntary and open to students majoring in either social work, recreation therapy, and nursing. Three, two-person teams, representing each discipline, participated in a two-part, unfolding simulation to assist with the discharge of an older adult from the hospital, and an assessment and care/teaching one week later in his home. Following the simulation, students wrote reflective journals about their experiences, and completed a brief survey. Post simulation responses to the RIPLS Questionnaire, and one of its subscales, yielded positive results in relation to improved attitudes towards interprofessional learning and positive professional identity. Students’ reflective journals reinforced the impact of interprofessional educational activities on acquiring knowledge about other disciplines. Lessons learned from this activity are being used to develop future interprofessional scenarios to augment the academic preparation of pre-professional healthcare workers in multiple disciplines.
Governing 'risky' sexualities: Representation of dementia and sexuality in the news media
Authors: Grigorovich Alisa
Published: September 2020

Drawing on critical scholarship on sexuality, disability and gerontology, this paper examines representations of dementia and sexuality across recent North American, European and Australian news media sources. Attending to the affects mobilized within these representations demonstrates how they support the constitution of the sexualities of persons with dementia as dangerous, and thus as requiring surveillance and restriction. I argue that the media stigmatizes persons with dementia by constructing them as either sexual predators or asexual victims. The first construct explicitly incites disgust and fear towards the sexualities of men with dementia, while the second elicits a superficial form of caring towards women with dementia. Such representations preclude the recognition and support of the sexual rights of persons with dementia, including their right to experience sexual pleasure.
A Duoethnographic Exploration of Disability Ally Development
Authors: Abes Elisa S. , Zahneis Megan E.
Published: September 2020

We explore through duoethnography how our relationship and dialogue across identity differences — a non-disabled white, cisgender, Jewish, lesbian professor and a disabled white, cisgender heterosexual student — mediated our development as disability allies. Couched in the relationship we developed through our work together in the academic discipline of disability studies, we explore structural and intersectional allyship, the power of language, and internalized ableism. We share the transformational learning that occurred for us through our duoethnographic dialogues and encourage vulnerable relationship-building across differences to explore the complexities of allyship. Both of us leave this study with more questions to explore, and we hope this work inspires others to engage in further reflections, dialogues, and allyship.

The Strategic Approach to Coping Scale (SACS) is a tool designed to measure coping strategies in terms of the Multiaxial Model of Coping. The aim of this article is to present our work towards adapting the SACS to the Polish cultural context. The Polish translation of this measure and the Rotter Incomplete Sentence Blank were applied to 1,074 Poles from 11 sample groups at risk of social exclusion. Principal component analysis performed on the data showed six components rather than the original nine. Second-order factor analysis carried out on the subscale scores revealed three factors partially consistent with the original theoretical assumptions. Convergences and discrepancies of the resulting structure versus the original one are discussed, along with reliability and the preliminary theoretical validity of the method.

Purpose of the study was analysis the particulars of morphological capability of the uterine scar after the previous Caesarean section.Materials and methods. The paper presents the data of morphological study of 100 fragments of uterine scar tissue, which were divided into two groups on clinical grounds. The first group included 50 fragments of the so-called “clinically capable” scars, and the second group included 50 fragments so-called “clinically incapable” scars. Assessment of the uterine scar tissue was performed by immunohistochemical study with monoclonal antibodies, as well as Van Gieson's and Masson's stain.Study results. More pronounced structural changes of the actual muscle fibers and microcirculatory disorders were observed in form of changes in architecture and areas of myometrium tissue homogenization in the group with “clinically incapable” scars using hematoxylin and eosin stain of the uterine scar tissue. In the differentiation of fibrous connective tissue using Van Gieson's stain method in the group of "clinically incapable" scars were manifested as replacement of muscular tissue with connective tissue with the formation of discrete muscular tissue fibers, and expressed perivascular fibrosis. Degenerative-ischemic changes of uterine scar tissue were found in the group of “clinically incapable” scars using immunohistochemical study with monoclonal antibodies to α-SMA. Pathomorphological study of the uterus scar revealed that hypoxic-degenerative changes and irregularity of maturation of collagen tissue, as well as pronounced replacement of muscle tissue with connective tissue with formation of separately immersed fibers of muscle tissue took place in the “clinically incapable” group. Immunohistochemical study with monoclonal antibodies to α-SMA and to CD31 revealed the more pronounced degenerative ischemic changes in the “clinically incapable” group.Conclusions. The revealed changes in the structure of the uterine scar tissue indicate that the state of myometrium, vascular component, regenerative capacity in the “clinically incapable” group on 43.4% worse than in the “clinically capable” group, and may manifest negatively with excessive functional loading of the uterine wall during pregnancy and childbirth.
Menopause. A problem that is not out of date. Specialist comment and updated data from the National Consensus on the Management of Patients in Menopause

Climacteric is a physiological transition period in a woman’s life during which the reproductive system involutive processes against the age-related changes are dominated in the body, and characterized by reduction of menstrual and generative function due to genetically programmed cessation of ovarian function.There are 4 periods of menopause: menopausal transition period, menopause, perimenopause and menopause.This document provides an overview of existing diagnosis and treatment methods of menopausal disorders in women, proposed algorithms for diagnosis and treatment of this disease to prevent heart diseases, osteoporosis and improve the quality of ukrainian women life.No need for hormonal laboratory research to diagnosis of perimenopause and menopause for most healthy women aged over 45 with the following features: vasomotor symptoms on a background of irregular menstruation in perimenopause; absence of menstruation for the last 12 months or appearance of menopausal symptoms after hysterectomy at menopause.The most common symptoms of menopause are vasomotor symptoms (hot flashes, night sweats, palpitations, labile blood pressure); psychological (emotional lability, depression, anxiety, irritability, sleep disturbances, poor memory and concentration); general physical symptoms (asthenia, headache, pain in muscles and joints, skin discomfort); urogenital and sexual (vaginal itching, burning, dryness and dyspareunia, frequent and urgent urination, decreased libido).The only pathogenetically effective method for the correction of menopausal disorders is menopausal hormone therapy. For this therapy are used natural estrogen (17β-estradiol, estradiol valerate, estriol) in combination with progestins (dydrogesterone) or androgens. It is possible parenteral (injections), transdermal, vaginal and oral hormone introduction.To correct the climacteric syndrome, urogenital disorders are used short courses of menopausal hormone therapy (for 1–5 years). For the prevention and treatment of osteoporosis menopausal hormone therapy lasts over 3 years if necessary, in combination with a bisphosphonate.

Objective of the study: was to evaluate the efficacy and safety of the Clofan® drug (clotrimazole, vaginal suppositories 500 mg) for treatment of candidiasis vulvovaginitis (CVV) in the third trimester with multiple pregnancy after using assisted reproductive technologies.Materials and methods. 32 women with multiple pregnancies were examined after using assisted reproductive technologies with CVV symptoms in the third trimester. General clinical research methods, vaginal smear microscopy, and culture studies using culture media were used to confirm the diagnosis. Spores and yeast fungal cells were isolated by smear microscopy of vaginal contents in all women. Examination was carried out before treatment, 1 week and 4 weeks after treatment. A single intravaginal suppository Clofan® 500 mg was used at night.Results. 7 days after Clofan® use clinical recovery was observed in 30 (93.8%) patients, and a significant symptoms reduction in 2 (6.2%) patients. Elimination of concomitant pathogenic and conditionally pathogenic bacterial microflora was achieved in 27 patients (84.4%). The absence of Candida albicans DNA in vaginal secretion after treatment was also noted in 27 patients (84.4%). The threat of preterm birth was observed in 2 cases (6.2%), premature discharge of amniotic fluid in 3 (9.4%) cases, candidal postpartum endometritis and joint discrepancy in the postpartum period were absent in all cases.Conclusions. The study showed the high efficiency of Clofan® in the treatment of CVV in the III trimester in multiple pregnancy after assisted reproductive technologies. This helped to reduce the frequency of the threat of premature birth, premature discharge of amniotic fluid and postpartum complications. Clofan® is an effective and safe topical preparation for CVV, and it also has a pronounced therapeutic effect on gram-positive bacteria and anaerobes. A low incidence of side effects against the background of its use was found.

Objective of the study: to evaluate the possible impact of manganese and nickel on the state of gonadotropic pituitary function and prolactin secretion.Materials and methods. For the study 2 groups of women were selected. The control group consisted of 38 women of reproductive age without reproductive system pathology. The main group consisted of 52 women who were diagnosed with polycystic ovarian syndrome (PCOS) in accordance with the Rotterdam Consensus criteria. Mass spectrometry was used in both groups to determine the indicators of manganese and nickel in serum. Evaluation of luteinizing hormone (LH), follicle-stimulating hormone (FSH) and prolactin in serum was performed by the enzyme immunoassay. To assess the statistical significance of data (p) we used the Mann-Whitney U-test and Student's t-test. Spearman's coefficient was used for correlation analysis.Results. Studies have shown that women with PCOS compared with the control group showed increased manganese levels (p = 0.0093) and nickel levels (p = 0.00019) in serum. Prolactin (p = 0.0024) and LH levels (p = 0.0001) were increased in the group of women with PCOS too. FSH in both groups practically did not differ (p = 0.074). Significant individual fluctuations in the secretion of gonadotropins and prolactin were observed in the main group. In authors’ opinion, this may be a sign of pituitary dysfunction. Only correlation between manganese-prolactin and manganese-LH levels was found in the group of women with PCOS. There was no relationship between level of trace elements and hormones in all other cases.Conclusion. Increased levels of manganese and nickel in serum were found in women with PCOS. Elevated prolactin and LH levels in women with PCOS may be associated with increased manganese exposure. Nickel exposure does not affect gonadotropin and prolactin levels in women with PCOS.
Use of placenta cryoextract for restoring the morphofunctional state of reproductive organs in animals with syndrome of premature ovarian insufficiency. Experimental substantiation

Published: September 2020

Objective of the study was to determine the placenta cryoextract impact on the restoration of the morphofunctional ability of the BALB/c mice uterus and ovaries after modeling their premature ovarian failure syndrome (POF) in the experiment.Materials and methods. A model of POF was created in 60 BALB/c mice which were divided into 2 groups of 30 animals: group 1 – with a model of POF without treatment, group 2 – with a model of POF and treatment with a placental cryoextract. The 3 (control) group included 30 intact BALB/c mice.Results. 4 weeks after creation of experimental POF in animals of group 1 histological examination of ovary showed an increase in interstitial tissue, replacing the generative structures of the ovary. An increased number of fibroblast cell elements and collagen fibers were also shown, indicating the growth of the organ stroma. Weight dropped sharply to 17.5 g, followed by a slow recovery in all animals of groups 1 and 2 after reproduction of the POF model. In this case, the weight in animals of group 2corresponded to the indices of control group already at 5th week and amounted to 21 g, reaching 22.1 g at 8th week. Animals in the 1 group restored their weight to 21.1 g only at 8th week. 5 weeks after POF simulation a complete restoration of estrous cycles occurred in 20% of in group 1 and in 70% in group 2. At week 8th the number of effective mating in group 1 was only 30%, while in group 2 this indicator increased to 80%.Conclusion. Intraperitoneal administration of cryopreserved placenta extract in mice with experimentally simulated POF leads to restoration of uterus morphological structure and partial restoration of ovarian structure with appearance of follicle-like generative elements in them.

Elektif cerrrahi planmalasında hastada bulunan demir eksikliği anemisinin preoperatif tedavi edilmesi morbidite ve mortalitede azalma ile ilişkili bulunmuştur. Oral demir tedavisinin yetersiz kaldığı ya da operasyon öncesi sürenin kısıtlı olduğu durumlarda İV demir tedavisi uygulanmalıdır. Gebelerde preoperatif dönemde klinik semptomu olmasa bile intraoperatif ya da postoperatif dönemde peripartum kardiyomyopati (PPKMP) gelişebileceği her zaman akılda bulundurulmalıdır.Bu olgu sunumuyla plasental invazyon anomalisi bulunan, sezaryen operasyonu sırasında ani KMP gelişen, peroperatif anemi tedavisi için intravenöz demir tedavisi uyguladığımız gebe hastayı güncel literatür ışığında tartışmayı amaçladık.
Intention and Goal-Conciliation
Authors: Rauen Fábio José
Published: September 2020

I analyze in this study potentialities of modeling communicative interactions assuming one can conceive processes of ostensive communication as converting practical intentions into informative and communicative intentions. So, one can only achieve collaboratively a practical intention through the recognition the speaker intends to make mutually manifest or more manifest certain set of assumptions by overtly or communicative ostensible stimuli. Firstly, I present the goal-conciliation abductive-deductive architecture in the case of self-conciliation, then I discuss a case of collaborative heteroconciliation, and finally, I draw some considerations about intention in the light of an approach to communication as a proactive agency.
