Published: January 2022

Pre-drying prior to freezing may reduce several freezing drawbacks. Nevertheless, drying may cause nutritional quality losses. Instant Controlled Pressure Drop process has been proposed to intensify pre-drying process. This research is dedicated to study the evolution of the main bioactive compounds (total phenolics, flavonoid, and tannins contents) of quince dehydrofrozen fruits. Fresh samples were subjected to air drying at 40 °C and 3 m s−1 air velocity down to a final water content of 0.3 g g−1 db. Pre-dried samples were Instant Controlled Pressure Drop (DIC) treated under different conditions, i.e. saturated steam pressure (P) and treatment time (t), following a 2-factor/5-level Experimental Design. Treated fruits were frozen at –30 °C then were thawed at 20 °C in order to study the impacts of DIC on phenolic compounds. Response Surface Methodology (RSM) confirmed that pressure was the most influencing parameter in terms of polyphenol, flavonoid, and tannins contents. Finally, DIC pre-treatment allowed the improvement of phenolic content retention compared to untreated DIC samples.

Authors: Kocherova V. V. , Popova N. G.
Published: January 2022

Background. The study of anemia causes in children born prematurely remains the urgent problem due to the continuous search for effective ways to prevent and treat it.

Objective. The aim of the study is to study the anemia severity in premature infants, peripheral blood test results (MCV, MCH, MCHС), serum iron, and ferritin at different gestational periods.

Materials and methods. 82 medical records of preterm infants were analyzed. 12 children were extremely premature (EР), 36 were very premature (VP), 27 were moderately premature (MP), and 7 were late premature (LP). The frequency of anemia, its severity, and laboratory indicators of iron metabolism were studied.

Results. In EР infants, anemia developed in 100% (severe and moderate form in 16.7%, mild in 66.6%), in VP — in 94.6% (of which severe form in 5.6%, moderate — 22%, mild — 67%). Severe forms were not detected in children over 32 weeks of gestation. In infants with ЕР, the iron level at 2 weeks Me (median) 10.6 μmol/l [8.8–12.1], which is lower than in the comparison groups: VP — 15.9 [12.3–18.9] (p = 0.007), MP — 18,7 [15.8–20.5] (p = 0.0002), LP — 14,0 [16.2–23.8] (p = 0.011). Serum ferritin in the EР group is 58.4 μg/l [52.8–71.7], lower than the level in children with OH — 165.5 μg/l [77.3–195] (p = 0.03). The indicators MCV, MCH did not reflect the etiology of anemia, MCHC is reduced in all groups. With oral subsidization of 3-valent iron, its level increase in EР: before treatment — 10.65 μmol/l [8.2–12.1], after 2 weeks — 21.95 μmol/l [17.8–23,9] (p = 0.011).

Conclusion. Severe and moderate degrees of early anemia of prematurity are diagnosed in the EР and VP groups. Significant deficiency of serum iron was detected in EР at the age of 2 weeks. MCHC less than 33.1% was registered in all gestational periods, it can be the marker of early anemia of prematurity. Iron supplement is required for EР.

Necrotizing fasciitis is a soft tissue bacterial infection that spreads rapidly resulting in the destruction of muscles, skin, and underlying tissue. Necrotizing fasciitis is defined as a fast and progressive inflammatory infection of the fascia leading to secondary necrosis of the subcutaneous tissue moving along the facial plane. Fournier gangrene is a type of necrotizing fasciitis involving the scrotum and perineal area. Patients suffering from acute necrotizing fasciitis require an effective regimen which includes surgical removal of devitalized tissues, systemic antimicrobials and mitigating underlying systemic disease processes. The burden of treating wounds following surgical debridement, on the other hand, can be challenging especially in the third world where resources are scarce resulting in suboptimal wound coverage and function. At primary care level we had the opportunity of using natural honey in 5 patients with non-healing wounds in either the lower limb or scrotum due to acute necrotizing fasciitis. This natural noninvasive approach offers a cost-effective and efficacious alternative to dermatotraction, skin grafting and negative pressure wound therapy. In these patients, the use of natural honey led to the restoration of the appearance and function of the fasciotomy wound especially in patients with co-morbidities or those refusing skin grafting due to cost, religious factors, etc. The authors present the clinical results followed by a discussion on the therapeutic properties of natural honey. This case series demonstrates the efficacy of topical raw honey as a catalyst for speeding the healing process by secondary intention thereby offering a safe and efficacious alternative for managing various wounds resulting from acute necrotizing fasciitis.

Background Soluble fiber has been shown to improve glycemic control by slowing the absorptions of glucose. And inositol has been shown to improve glycemic control in type 2 diabetes (T2D) and gestational diabetes via recruiting glucose transporter type 4 (GLUT4) to cell surface. However, neither inositol supplementation nor combination of inositol and soluble fiber supplementation has been studied in overweight. Objective To investigate if supplementation of inositol improves biological markers of glycemic control overweight and obesity, and that supplementation of inositol in combination with soluble fiber have synergistic effects to further improve these markers. Design A single cohort, uncontrolled, test-retest design was planned to be implemented over 5-weeks in which the participants supplemented 2 grams of myo-inositol twice daily for 4-weeks and then 2 grams of myo-inositol plus 2 grams of soluble fiber each twice daily for 1-week in overweight and obese subjects. Only one overweight subject was able to complete both phases of supplementation due to coronavirus disease-2019 (COVID-19), therefore the study is reported as a case study. Results Supplementation of 4 grams of myo-inositol daily for 4-weeks resulted in improved glucose parameters and lipid parameters including fasting blood glucose, post-prandial blood glucose, total blood cholesterol level, blood high-density lipoprotein (HDL) cholesterol level, and blood triglyceride level. The combination of inositol and soluble fiber supplementation further improved the total blood cholesterol level. Conclusion These results indicate there is potential benefit of inositol supplementation for sub-clinical hyperglycemic, overweight subjects on glycemic control.

Published: January 2022

Introduction Giving care to a patient at the end-of-life can be a challenging experience. The responsibilities of caregiving may include executing complex physical and mental tasks, financial planning, patient care, decision-making, emotional support and coordination of care. This mixed-methods observational study aims to identify the psychosocial and economic effects of caregiving for terminally-ill patients by carers on the Hospice Africa Uganda Kampala program. It used both quantitative and qualitative data of caregivers caring for terminally-ill patients attending Hospice Africa Uganda Kampala. Simple random sampling was conducted to select caregivers who were invited to participate in the study. Results Results indicate that the majority of patients who were receiving palliative care (60.9%, 103) had been diagnosed with cancer. Most participants (62%, n=105) had spent less than one year caring for their patients, while (18%, n=31) were cared for between 1-5 years. Our results show that the responsibility of caregiving has significant effects on the psychosocial well-being of caretakers. In particular, it reduced the amount of time they spent attending social gatherings and caring for their children, their religious commitment (p<0.05), as well as their level of fatigue and exhaustion (p<0.05), and negatively impacted job finding activities. Conclusion Terminal caregiving has significant effects on the psychosocial well-being and incomes of caretakers, and their ability to find a job alongside caring for the patient. Based on these findings, it is therefore recommended that caregivers be given ongoing support to help them provide care to their own family members and patients with life limiting illnesses early in the disease trajectory.

Background Convulsion is an event that can emotionally traumatise most parents. Inadequate knowledge regarding convulsion can cause parental anxiety. Aim This research sought to investigate the knowledge, attitudes, concerns and practices of parents regarding convulsion in children under five-years. Methods The study employed a community based cross-sectional survey design. Purposive, convenient and snowball samplings were used to select the study site and enroll participants to the study. The study was conducted in Muea Community, Buea Health District in Fako Division, South West Region of Cameroon. The study participants were made up of parents of children under 5-years of age and who had witnessed convulsion in a child. Respondents who met the inclusion criteria and gave their consent to participate in the study were selected. Data was collected using a semi-structured questionnaire made up of both open and closed-ended questions. Data was collected on the knowledge, attitudes, concerns and practices of parents regarding convulsions in children. Data collected was entered using a pre-designed EpiData version 3.1 and data from open-ended questions were analysed using systematic process of thematic analysis. Results A total of 100 respondents participated in the study. The study revealed that more than half of the respondents 53.7% had good knowledge on convulsion, 61.9% of the respondents had positive attitudes towards convulsion and 51.4% of parents had good practices regarding convulsion. This study also revealed that knowledge of convulsion had an association (p=0.05) with gender and marital status but was not dependent (p>0.05) on age and level of school attained. Conclusion The study concluded that even though more than half of the respondents were knowledgeable on convulsion, there is still need for proper parental education as inappropriate attitudes and practices like putting the child’s head in the toilet pit, which can lead to complications are still being practiced.

The authors consider themselves organizational and leadership developers. They have been active in the corporate world for a long time, working and consulting. Their work is based on morphological psychology, a psychological approach developed by Wilhelm Salber, that aims at understanding behavior as it is in constant state of change. It is not about measuring and explaining, but about describing and understanding how things interact and change. With its comprehensive approach in describing everyday life, morphological psychology is an excellent tool for examining and understanding corporate culture. In this book, the authors examine what constitutes leadership in the corporate work environment psychologically, how “change” is managed, and what happens between “perfection” and “explosion” in leadership.

Most of these options are invasive, which can be troublesome for patients, and also have side-effect profiles. Pulsed-electro magnetic stimulation therapy (PLMST) has gained interest in the field of sexual medicine. In the given case author presented a successful effect of in a case of erectile dysfunction.
"They would not like it if men taught in the foundation phase": SGBs' perceptions of the employment of male FP teachers
Authors: Kagola Obakeng , Khau Mathabo
Published: January 2022

Efforts to recruit and retain men in the Foundation Phase (FP) teaching and learning have been made all over the world. In South Africa, School Governing Bodies (SGBs) are tasked with the responsibility of diversifying schooling by recommending to the Department of Basic Education (DBE) the employment of teachers in all educational phases. Two and a half decades after the dawn of democracy in South Africa, the teaching of children in the early years is still dominated by women. This study explores how SGBs in the Eastern Cape province of South Africa approach the employment of male teachers in FP. Using a qualitative research approach, we used a semi-structured focus group discussion to generate data with five SGB parent-component members. We analysed the data thematically and found that SGBs' employment of male FP teachers is based on societal constructions of gender over employment policy guidelines. The SGB members showed a lack of policy understanding and at times misinterpreted the policies. These findings have implications for education policymakers and teacher training institutions in facilitating the smooth incorporation of males into FP teaching.
Measuring preservice teachers' ethnocentrism: A South African case study
Authors: West Joyce , Evans Rinelle , Jordaan Joyce
Published: January 2022

High degrees of ethnocentrism indicate intolerance towards that which is not one's own. When displayed by teachers towards learners, such attitudes may have detrimental effects on learner performance and hinder transformation in South African classrooms. Using Vygotskian sociocultural theory of human learning as a theoretical framework, this quantitative case study reports on the outcome of the electronically administered Generalised Ethnocentrism survey that measured 1,164 preservice teachers' ethnocentrism at a private higher education institution. Apart from providing biographical data, respondents answered 22 statements on a 5-point Likert-type scale about their beliefs pertaining to their own and others' culture, customs, and values. Results showed that preservice teachers manifest varying degrees of ethnocentrism but that those who attended multicultural schools scored significantly lower on the ethnocentrism scale than those who attended mono-ethnic schools. Respondents in the last stretch of their studies also obtained lower scores on the GENE scale than first and second years. This would suggest that greater exposure to social diversity and interaction across cultures plays a fundamental role in shaping ethnocentric beliefs and attitudes. An unexpected finding was that the instrument did not provide similar results as found in several studies, thus creating misgivings about its applicability in a context in which a minority ethnic grouping no longer held power. Policy makers and teacher educators should consider interventions to create more explicit and purposeful opportunities for preservice teachers to gain multicultural exposure and develop cultural competence. Assisting prospective teachers to identify their own ethnocentrism and knowing how to counter the many prevailing ideologies that promote, however inadvertently, ethnocentrism would prepare them for the realities of their future classroom and equip them to act as agents of change.

The article is devoted to the technical channels of Transient Electromagnetic Pulse Emanation (TEMPEST) information leakage. Methods of detection and measurement of TEMPEST, as well as broadband signals in general cases are briefly presented. The features of detection and measurement of broadband TEMPEST signals of modern digital interfaces (for example, DVI, HDMI, DisplayPort) are considered. These digital interfaces are selected as the most relevant at the moment, against analog ones that are coming out of mass use (VGA). The review of the main approaches to the identification of such signals is carried out. Detection and measurement of broadband TEMPEST signals is a non-trivial task, since both TEMPEST signals and broadband signals themselves have a low signal-to-noise ratio. A laboratory stand (an alternative measuring platform) is described in detail, where practical studies were carried out to identify and measure the broadband TEMPEST using the example of the HDMI interface. The influence of the shield camera on the results of research in cases of complete and partial screening of the object under study is demonstrated. The influence of the bandwidth value during measurements of the broadband TEMPEST on the displayed spectrum of such a signal is shown. After reaching a certain value of this bandwidth, the displayed spectrum becomes clearly distinguishable against the background of noise. The measurement of the signal levels of the broadband TEMPEST was carried out in two ways. The first method assumed that the spectrum of the broadband TEMPEST signal is continuous. In the second method, it was assumed that the spectrum of such a signal is discrete. Based on the results of these measurements, a conclusion was made about the actual nature of the spectrum of the signals of the broadband TEMPEST.

Reading comprehension has a critical importance for almost every aspect of individuals’ life. The aim of this study is to reveal the relations among students’ perceptions of their Turkish language teachers’ behaviours that encourage reading engagement, levels of reading enjoyment, reading self-efficacy, and reading success within the frame of a model, using PISA 2018 Turkey data. The study is based on the correlational research model and the sample includes 6450 (F= 3247, M= 3203) students who completed the PISA 2018 Turkey questionnaire. The data obtained from the PISA 2018 database were analyzed using the structural equation model (SEM) and the sobel test. SEM analyses revealed that the hypothesized model well fits the data and all the regression paths in the model are statistically significant. According to the research findings, teachers’ behaviours that encourage students’ reading engagement (TBESRE), reading enjoyment, and reading self-efficacy have significant direct effects on reading achievement. In addition, TBESRE has significant indirect effects on reading achievement through reading enjoyment and reading self-efficacy, and that reading self-efficacy has a significant indirect effect on reading achievement through reading enjoyment. Considering the findings of this study, it is recommended that teachers implement practices to encourage students' participation in reading activities and develop educational interventions to improve reading enjoyment and reading self-efficacy.

Authors: SÖZBİR Metin , UYSAL Ünal
Published: January 2022

Gaz türbinlerinde sıcaklık arttıkça verim ve güç artmaktadır. Fakat çok yüksek sıcaklıklara (≈2000°C) maruz kalındığında; sıcak gaz çıkış yolu üzerinde bulunan ekipmanların maruz kaldığı mekanik ve ısıl zorlamaların etkisi ciddi ölçüde arttığından özellikle gaz türbin kanatlarının soğutulması önem kazanmaktadır. Bu nedenle türbin kanatlarının mekanik veya ısıl zorlamalardan korunması ve güvenli şekilde çalışmasını sürdürebilmesi için etkin bir soğutma gereklidir. Üretici firmalar ve bilim adamları gaz türbinlerinin optimum verimi için türbin kanatlarında farklı soğutma yöntemleri geliştirme çalışmaları yapmaktadırlar. Bu geliştirme çalışmalarının çoğunluğunda çok kademeli ve sıralı yapıya sahip çarpmalı jetler ile jet geometrileri üzerinde odaklanılmıştır.
Bu çalışmada; kanat soğutma kanalına geometrik olarak benzer bir model üzerinde; hidrolik çapları eşit, dairesel, kare ve eşkenar üçgen tipli jetler kullanılarak, farklı Reynolds sayılarında hedef plakadaki ısı geçiş katsayısı dağılımı sıvı kristal termografi yöntemiyle deneyler yapılmıştır. Deneylerden elde edilen veriler kullanılarak jet geometrisinin, jet çapının, jet-hedef plaka aralığının ve Re sayısının yüzey ısı geçiş katsayısına etkisi araştırılmıştır. Deneysel çalışmalar sonucunda; ısı geçiş katsayısının Re sayısının artması ile akış yönünde arttığı görülmüştür. Plakalar arası aralık ve jet hidrolik çaplarının artırılmasıyla durağan bölgelerin arttığı ve ısı geçiş katsayısının bu bölgelerde azaldığı tespit edilmiştir. Çapraz akış, hedef-jet plaka aralığının artırılması ile akış yönünde azaldığı görülmüştür. En yüksek ortalama ısı geçiş katsayısının eşkenar üçgen jet plakalı modelde ve hedef plakla üzerinde en homojen ısı geçiş dağılımının dairesel jet plakalı modelde meydana geldiği tespit edilmiştir.
Review on the epidemiology of Bovine Rotavirus and its public health significance
Authors: Abebe Garoma Gichile
Published: January 2022

A literature review was made to assess the epidemiology, public health importance, diagnostic and control methods of bovine rotavirus. Rotavirus is the genus name under the family Reoviridae which is characterized by segmented genome. The emergence of new serotypes of the virus is related to the segmented nature of the viral genome which allows reassortment during mixed infections. The rotavirus genome consists of 11 double-stranded RNA gene segments encoding 6 nonstructural (NSP1–6) and 6 structural (VP1–4, VP6–VP7) proteins. Rotavirus A is a zoonotic disease and in children less than five years old, human rotavirus is reported to be the most common cause of gastritis. In animals, rotavirus infection usually affects calves within four weeks of age, causing huge economic losses due to death, reduction in weight gain and treatment costs. Bovine rotaviruses are globally distributed and cattle strains have been classified into 12 G types and 11 P types and among them G6, G8 and G10, and P [1], P [5] and P [11] are commonly prevalent bovine strains. However, the presence of 14 G type and 17 P type serotypes from human have reported in different surveillance studies worldwide. Among these, combinations of G1P [8], G2P [4], G3P [8], G4P [8], G9P [8] and G12P [8] are the most common human strains which are responsible for majority of human Rotavirus diseases. The virus is primarily transmitted by fecal-oral route or by direct contact. The excreta from infected animals and humans, excreta contaminated food; water, pasture and air are the potential source of infection for both animal and human rotaviruses. Age, seasonal pattern, strain diversity, poor herd management and housing system, host nutritional and immunological factors are important risk factors associated with rotavirus disease occurrences. The widely used diagnostic methods for detection of rotavirus antibody in human and animals are Enzyme-Linked Immunosorbent Assay (ELISA) and immune-chromatography while the presence of the rotavirus/antigen is identified by Enzyme Immunoassay (EIA). Electron Microscopy (EM), polymerase chain reaction (PCR) and nucleic acid hybridization. Vaccination is the primary strategy to prevent and control of bovine and human rotavirus infections. High level of antibody in pregnant animals is achieved through live attenuated and inactivated vaccines when administered at the late stage of pregnancy. In human, the two currently used vaccines are the RV5 vaccine (USA) and the RV1 vaccine (Belgium) types.

Indication-prescription study for the management of conjunctivitis in a Colombian population v1
Authors: Machado Alba Jorge
Published: January 2022

Introduction:Conjunctivitis is one of the most common ocular pathologies. Its treatment depends on its etiology, but an excessive use of antibiotics and corticosteroids, which in many cases are contraindicated, has been described. Objective: To describe the prescription patterns of medications used to treat conjunctivitis in a Colombian population. Methods: This was a cross-sectional study on the pharmacological treatment of patients diagnosed with conjunctivitis based on a drug-dispensing database of approximately 8.5 million people affiliated with the Colombian Health System. Some sociodemographic and pharmacological variables and comorbidities were considered. A descriptive analysis was performed. Results: A total of 8,708 patients were identified; they had a median age of 44.7 years, and 59.3% were women. The most common causes of conjunctivitis were unspecified (53.1%) and allergic (37.4%). The most commonly used drug was olopatadine (26.1%), followed by dexamethasone with neomycin and polymyxin B (25.0%). A total of 97.0% of the patients received ophthalmic prescriptions, while 12.8% received systemic medications. Glucocorticoids (40.3%), antibiotics (37.7%) and antihistamines (31.7%) were the most commonly used groups of ophthalmic drugs. Glucocorticoids and ophthalmic antibiotics were the medications most frequently prescribed by general practitioners for the treatment of viral or bacterial conjunctivitis. Conclusions: Many patients with conjunctivitis are not being managed according to the recommendations of clinical practice guidelines, which highlights that the widespread use of antibiotics with ophthalmic glucocorticoids could be considered potentially inappropriate prescriptions in many cases.
Психологическая классификация компьютерных игр
Authors:   Иркутский государственный университет, Кыштымова И.М. , Тимофеев С.Б. ,   Иркутский государственный университет
Published: January 2022

Авторы определяют компьютерную игру как многоуровневую и многокомпонентную систему, компоненты и уровни которой могут обладать различной степенью тесноты связей. На основе этого выдвигается предположение о том, что классификации, концентрирующиеся на отдельных компонентах игры, мало эффективны для изучения психологического влияния конкретных игр на личность геймеров. Отсутствие универсального классификационного конструкта, позволяющего осуществлять дифференцированный психологический анализ компьютерных игр обусловил актуальность исследования. Предлагаемая классификационная модель, состоит из слабо связных между собой компонентов с разной степенью выраженных в большинстве существующих игр. Модель представлена семью содержательными уровнями: двумя базовыми, свойственными для всех игр, и пятью вариативными. В состав уровней входят тридцать два компонента, степень выраженности которых может определять классификационные характеристики игры.

Published: January 2022

The installation of industrial servo systems and the determination of control parameters are limited to the skills and knowledge of the commissioner. In addition, commissioned systems are often not re-optimized if environmental influences or loads change. The goal of this research is to create an artificial neural network (ANN) model for servo systems that will keep the servo system's proportional, integral, and derivative (PID) parameters working optimally. For this process, a machine condition monitoring algorithm developed with the ANN technique, which uses the data such as actual current, torque, power, position to be obtained from the servo system on an industrial controller, for the control and rearrangement of the parameters.

Published: January 2022

The aim of the study was to determine the state of psychophysiological functions of skilled athletes specializing in academic rowing, in relation to the level of existing stress, emotional stability and the effectiveness of mental self-regulation and adaptability. To determine the state of psychophysiological functions, the maximum rate of movement of the hand (according to the method of tapping test) used diagnostic complex "Diagnostics-1" (MV Makarenko, VS Lyzogub). To study the strategies of coping with stress (coping strategies) and to determine the priority style of coping with stressful situations in athletes, the questionnaire "Identification of individual coping strategies" by E. Heim was used. To assess the current mental state of athletes (namely – the level of existing stress), emotional stability and effectiveness of mental self-regulation and adaptability, the test of color choice M. Luscher was used. In the studied group of athletes revealed the prevalence of respondents with a high level of stress resistance, high and medium level of emotional stability, average efficiency of mental self-regulation and adaptability. The most common coping strategies among the surveyed athletes were: in the cognitive sphere – "preservation of self-control", in the emotional – "optimism", in the behavioral – "distraction". In general, the use of adaptive stress management strategies outnumbered non-adaptive and relatively adaptive strategies among athletes. Specific psychophysiological markers of stress resistance, efficiency of mental self-regulation and adaptability of the examined athletes were indicators of strength and efficiency of sensorimotor activity. Emotional stability of the surveyed athletes was associated with the strength and functional mobility of nervous processes. The identified relationships between indicators of psychophysiological functions and psychological characteristics of athletes can have prognostic value and be used to optimize sports improvement in this sport.

Mushroom extracts show the multifunctional activity and have a wide range of applications for the treatment of various diseases, including cancer. However, the full composition of the compounds that produce macromycetes that exhibit antitumor properties has not yet been established. Impaired glucose metabolism and activation of gamma-glutamyltranspeptidase (GGT) in tumor cells may be a key marker of biochemical anaplasia in neoplasms. The aim of the study was to investigate the effect of crude extracts and cytokinin fractions isolated from the mycelial biomass of medicinal mushrooms on the biological properties of cells of hepatocyte-like cells of the HepG2 line (human hepatocellular carcinoma). The objects of the research were pure mushroom cultures of Hericium coralloides, Fomitopsis officinalis, Trametes (Coriolus) versicolor, Pleurotus ostreatus and Morchella esculenta. Cytokinin fractions from the extracts were isolated by centrifugation followed by fractionation and purification using ion exchange chromatography. Qualitative and quantitative analysis of cytokinins was performed by high-performance liquid chromatography. GGT activity was determined using the kit "Filisit" (Ukraine), glucose level – glucose oxidase method, with modifications for the cellular culture medium. The analysis of mycelial biomass of medicinal macromycetes revealed the presence of transzeatin, zeatin riboside, zeatin-O-glucoside and isopentenyladenine, that showed high activity in relation to cytokinin synthesis. Inhibition of glucose diffusion from the cultivation medium with the use of crude extracts and cytokinin fractions of medicinal mushroom and a decrease in GGT activity, more pronounced with the action of cytokinin fractions, compared with crude extracts, was noted. The difference between the effects of crude extracts and cytokinin fractions indicated the complex nature of the action of biologically active substances of medicinal mushroom. Presented results regarding the effects of crude extracts and cytokinin fractions of medicinal mushroom showed a normalizing effect on the main metabolic parameters which change in tumor cells, as a mechanism of biochemical anaplasia.

Introducción: La educación superior con un enfoque educativo basado en la valoración de la diversidad funcional y el reconocimiento de la existencia de barreras, permite a las personas ser incluidas efectivamente en la sociedad. Se analizaron factores como falencias y potencialidades que pueden influir en la vida universitaria de personas con o sin discapacidad física, mental o sensorial, para el acceso, la permanencia, participación y el egreso oportuno de la misma. Metodología: Se efectuó un estudio descriptivo de corte transversal, mediante análisis univariado y bivariado, que relaciona variables sociodemográficas con el nivel de funcionalidad en cuanto a la capacidad de desempeño y participación, considerando los 6 dominios del cuestionario para la Evaluación de la Discapacidad de la Organización Mundial de la Salud (Whodas 2.0). Resultados y Discusión: Se evidencia la importancia de desarrollar un diagnóstico inicial de los estudiantes que ingresen a las universidades con y sin discapacidad que limitan su participación y desempeño educativo, con el fin de potenciar sus habilidades, capacidades e intereses, para alcanzar un desempeño óptimo. Conclusiones: Se evidencian dificultades en el grado de funcionalidad de los dominios evaluados por el Whodas 2.0, lo que puede incrementar los porcentajes de deserción de los estudiantes principalmente en los primeros semestres.

Background Unstable pelvis injuries are one of the most difficult and severe trauma of musculoskeletal system that needs emergency measures. Aim of the study is the optimization of treatment tactics in unstable pelvis fractures in polytrauma patients. Маterial and methods This is a prospective study of treatment results of 96 polytrauma patients with unstable pelvic fractures type C. Unilateral injuries of the posterior pelvic ring were 85.42 % (n = 82), bilateral injuries were 14.58 % (n = 14) of cases. Diagnostic complex included physical examination, laboratory tests, X-rays and CT. Examination was carried out simultaneously with anti-shock measures and intensive care. Primary basic stabilization of the pelvis with an external device and fixation of the posterior ring were performed. Results and discussions Three patients died (3.13 %), the remaining 93 (96.87 %) patients completed treatment with good outcomes. The biomechanics of pelvic injuries shows us the necessity of external fixation. Unstable pelvis injuries in polytrauma patients with hemodynamic instability should be temporary stabilized to decrease the intrapelvic volume. Conclusions Primary stabilization of the pelvic ring is an effective therapeutic tactic that leads to a significant reduction in the severity of patients’ condition, prevention of post-traumatic complications and early functional recovery of the damaged organs.

Introduction Analysis of psycho-emotional aspects in children suffering from spinal deformities demonstrates a high level of dysfunctionality in mechanisms of personal and intra-family adjustment. There is a paucity of publications on the problem. Objectives included multidimensional psychometric assessment of parents' attitude toward children with spinal deformities and the correlation with psychological characteristics of patients. Material and methods Results of a survey performed for 45 patients who underwent operative treatment for spinal deformities of different etiology and their parents were reviewed. The patients' age ranged from 7 months to 17 years inclusive. Validated questionnaires used as survey tools included the "DOBR" questionnaire, FACES-3, SDQ and DERS. Patients were assigned to two age-related groups, Juniors aged from 7 months to 6 years inclusive and Seniors aged from 7 to 17 years inclusive. An intergroup and correlation analyses were performed in the study groups. Results Multidimensional analysis showed that parents of children with spinal deformities tend to downgrade the severity of the child's condition neglecting postoperative prescription standards that was more common for Seniors (p = 0.001). Parents look toward the maximum intra-family cohesion but do not have the necessary knowledge to achieve it. Emotional problems and social adjustment difficulties are more common for Seniors (p = 0.031). Conclusion Lack of adequate parental knowledge about the child's disease is the key factor behind the imbalance in intra-family functioning. Therapeutic intervention and parent management training can facilitate to psycho-emotional well-being in the family and postoperative improvements for maladapting children with spinal deformities.
El acervo autoritario en el sistema jurídico español y su impacto en la devaluación de la huelga como derecho social fundamental

This article carries out a philosophical-legal and genealogical analysis of the continuity, in the current regulation of the right to strike in Spain, of an authoritarian heritage from the Franco dictatorship, based on national unity, national security and public order. This heritage, which devaluates the character of the fundamental social right to strike and the very functioning of Spain according to the rule of law, is evidenced in the legal provision that regulates it, Royal Decree-Law 17/1977, approved during the transition to democracy, and in a criminal labor law that has limited its essential content.

Background: Meconium is a sterile, thick, black-green, odourless material that results from accumulation of debris in fetal intestine during the third month of gestation. The risk factors for meconium-stained amniotic fluid (MSAF) are both maternal and fetal. MSAF is associated with higher rate of caesarean delivery, increased need for neonatal resuscitation and meconium aspiration syndrome. This observational study was undertaken so that such expecting mothers can be screened at an early stage and prompt intervention can be done to minimize neonatal morbidity and mortality.Methods: This prospective observational study was conducted in department of paediatrics of Sri Guru Ram Das University from December 2014 to June 2016 included all deliveries with meconium stained amniotic fluid excluding Twins, neonates with congenital malformations, multi organ dysfunction or requiring surgical intervention.Results: The incidence of MSAF was 3.42% with 10.5% mortality. Various maternal factors including multiparity, bad obstetric history, pregnancy-induced hypertension (PIH), intrauterine growth restriction (IUGR), maternal diabetes, anaemia and non-reassuring cardiotocography (CTG) record were found to be statistically important and associated with poor outcome.Conclusions: MSAF and poor neonatal outcome is related to antenatal care. Thus, good antenatal and perinatal care can prevent morbidity and mortality in neonate by early identification of signs of fetal distress and passage of meconium inutero and improve outcome.
