Authors: K.V. Klester , E.B. Klester , V.A. Elykomov
Published: July 2023

Objective: to analyze the clinical manifestations and frequency of postcovid syndrome in COPD patients, depending on the presence of metabolic syndrome.
Materials and methods. There were 222 patients under outpatient supervision for a year after the new coronavirus infection (NCI): group I – 15 patients with COPD without MS, group II – 155 patients with COPD with MS. Group III (comparison) - 52 patients with MS without COPD, comparable in age and gender. Patients were included in the study as NCI became ill. During visits after 6 and 12 months, a comprehensive examination was carried out with an assessment of complaints, objective status, and a quality of life questionnaire; the HADS questionnaire, the frequency of exacerbations of COPD, blood oxygen saturation (SaO2), spirometry, 6-MWT (exercise tolerance), laboratory tests (CBC, biochemical blood analysis); chest CT; echocardiography. All patients filled out a questionnaire for the primary self-assessment of the health of patients who had undergone NCI. This study was conducted in accordance with the principles of the Helsinki Declaration; written informed consent was obtained from all patients before being included in the study.
Results. Postcovid syndrome is more often detected in patients of group II (34.3%; p<0.05), less often in group I and III (6.7% and 18.4%, respectively). When assessing the symptoms of NCI in COPD patients with MS, even after a year of follow-up, the following prevailed: weakness (81.1%), subfebrility (48.5%), pain in the heart area (40.1%). When analyzing the psychoemotional status, it was noted that in patients with MS on the background of COPD, the level of personal and situational anxiety and depression in the post-covid period increased 2.5 times and was maximally expressed in the long-term period (a year after the NCI).
The greatest impact of the transferred NCI had on the aggravation of the degree of dyspnea in group II patients after 6 and 12 months (p<0.05) and an increase in the frequency of exacerbations (p<0.05).
Conclusion: The presence of MS in patients with COPD causes more frequent development of postcovid syndrome, which requires mandatory medical correction. Of the clinical manifestations of NCI, weakness, muscle pain, prolonged subfebrility with night sweats, anxiety and depressive disorders persisted for the longest time. The course of COPD was characterized by an increase in the number of exacerbations.

Assessment of the intensity of free-radical processes that change their activity in response to exogenous and endogenous intoxication is carried out by biochemical methods of determining the state of the antioxidant system of the body (AOS). This is a complex of methods, one indicator of which is the level of lipid peroxidation by accumulation of malondialdehyde (MDA).
Revealing certain features of the mutually regulating influence of the processes of lipid oxidation and antioxidant system of the body may serve as a criterion for evaluation and prognosis of the course of the pathological process in endogenous toxicity and correction of therapeutic tactics.
Peroxidation in the elderly and old age is of particular importance, since there is still no definitive opinion on the dynamics of the physiological course of lipid peroxidation in this age group, the criteria for the transformation of peroxidation reactions from normal to pathogenic.
In this work we evaluated the antioxidant activity and duration of the preservation effect on the antioxidant protection of the organism of the drug "Tameron" (sodium luminol) with different methods of parenteral administration in the model of age-related lower primates.
At intramuscular and intravenous injection of the drug "Tameron" in experimental animals a marked decrease in the concentration of MDA in blood plasma was observed. This suggests a decrease in the activity of peroxidation processes and activation of antioxidant protection of the body, which is especially important in age-matched animals.
It should be noted the preservation of low indicators of oxidative stress indicator in the representatives of the experimental group for a long time period (about a year) and suggest a pronounced antioxidant prolonged effect of the studied preparation, accompanied by alignment of MDA concentration throughout the group to statistically similar values.

Authors: M.V. Skvortsova , Kh.M. Bataev
Published: July 2023

To improve the quality of drug care for patients with arterial hypertension, using a sociological survey, we determined prognostic parameters that determine the risks of developing the disease, which included: hereditary burden, duration of the disease, blood pressure indicators, the presence of concomitant diseases, the frequency of blood pressure measurement, lifestyle, adherence to treatment, quality of life indicators, assessment of the significance of factors in the choice of antihypertensive drugs.
The results of the analysis of patient survey data showed that most patients do not underestimate the significance of these parameters, do not have enough knowledge necessary for effective treatment.
As an organizational and functional form of improving the professional interaction of medical and pharmaceutical specialists in order to meet the information needs and improve the quality of life of patients, the creation of a medical and pharmaceutical school was recommended. The main purpose of the functioning of the Medical and Pharmaceutical School is to increase the educational level of patients.

Authors: V.I. Shemonaev , A.V. Mashkov , A.S. Patrushev
Published: July 2023

With the advent and introduction of composite materials into dental practice at the end of the 20th century, patients' requirements for the aesthetics of prostheses have increased dramatically. At about the same time, a new material appeared – zirconium dioxide, which has good aesthetic qualities, excellent strength characteristics, chemical stability and bio-inertia. However, for all its advantages, it also has a number of disadvantages, one of which is poor adhesion to fixing cements. To date, many methods have been proposed to improve the adhesion of prostheses made of zirconium dioxide, each of which has its own strengths and weaknesses. The purpose of this review is to analyze, compare and systematize existing methods and materials proposed to improve the adhesion of zirconium dioxide to fixing cements, as well as their evaluation to study current trends in surface conditioning methods with predictable results. Materials and methods. This study was conducted using the PubMed search engine. 42 articles were selected for the time period from 2016 to 2022. Search keywords: zirconia, zirconia adhesion, bond strength test. The articles used were selected according to the following criteria: publications in English, in vitro studies, studies with shear/tensile strength tests, systematic reviews. Only articles related to dentistry were considered. Conclusions. The selected literature describes many methods that enhance the adhesion of zirconium to fixing cements. However, their comparison and evaluation are difficult due to the authors' use of various tests and thermal cycling time. This is confirmed by our comparative evaluation of these methods according to criteria independent of each other. Currently, there is no generally accepted and standardized protocol for adhesive preparation of the surface of structures made of zirconium dioxide, which gives time-stable results. Additional research is needed.

The problem of treatment of teeth with endoparodontal lesions remains relevant today. This article discusses a clinical case of treatment of a patient with chronic generalized periodontitis who has a combined lesion of the periodontal and apical periodontal in the lower premolar region. The purpose of the study is evaluation of the effectiveness of the treatment of endoparodontal tooth lesion and the further possibility of prosthetics of the tooth.
Materials and methods. For the diagnosis of pathology and in the course of treatment, the following additional research methods were used: CT, OPTG and targeted radiography. Mechanical processing was carried out with manual steel tools. Drug treatment was carried out using solutions of 3% sodium hypochlorite and 17% EDTA For temporary obturation of the root canal, a material based on calcium hydroxide with the addition of a radiopaque substance was used. To further improve the quality of disinfection and adhesion of the filling material to the root canal wall, the method of photodynamic action on the root canal wall was applied in the 2nd visit. Permanent obturation of the root canal was carried out by the method of lateral condensation of gutta-percha in combination with a siler based on ecoxide resin. The reduction of the focus of bone tissue destruction was confirmed clinically and radiologically. Thus, we managed to avoid tooth extraction and it became possible to use this tooth as a support on a non-removable orthopedic structure.

Published: July 2023

The article discusses the causes of the development of radiation-induced heart disease - one of the significant complications of chest radiation therapy. Treating cancer with this method triggers the mechanism of pathological changes in the heart. There are a number of risk factors contributing to this complication in patients. The most common clinical forms of radiation-induced heart disease are identified, as well as a characteristic of their signs. The timing of the appearance of these signs for each form may be different, in addition, they vary depending on the reason for the use of radiation therapy. The possibilities of diagnosing selected conditions are indicated, which oncologists and doctors of other specialties should actively apply in the tactics of managing patients who have undergone oncological diseases of the mammary glands or chest organs. These diagnostic methods are not different from the main methods of diagnosing cardiac diseases, they are affordable and safe. The article also provides methods for the primary and secondary prevention of radiation-induced heart disease, which begin with the choice of a method of treatment for an oncological patient. Now there are many radiotherapy options that reduce the dose and area of radiation, which can minimize the risks of deterioration in the quality of life and prognosis of the patient. The next important principle is the correction of lifestyle and modifiable cardiovascular risk factors. Also indicated are variants of drugs used in cardiac practice, with the help of which, possibly, in the future, the prevention of radiation-induced heart disease will be carried out, but so far they are at the stage of clinical trials.

This article discusses the problems of providing drug care to children. The aim of the work was to identify the prerequisites for the creation of a Russian indicative list of medicines for children based on the assessment of rationality and structural analysis of drug prescriptions in pediatric practice. The study used the methods of content analysis, statistical analysis, graphical method. The sample consisted of 2,900 prescriptions for drugs and other pharmacy products made by doctors of various profiles to children aged 0 to 17 years. The study showed that 92% were medicines (MP), the rest - other pharmacy products (biologically active additives, cosmetics, medical products, etc.). An analysis was also carried out by the frequency of prescriptions, by dosage forms, by anatomical-therapeutic-chemical (ATC) classification and by prescriptions outside the instructions (off-label, in our study, we attributed to off-label those cases when drugs were prescribed to children aged , not officially permitted in the instructions for medical use). Nurofen for children (Ibuprofen) oral suspension was the most frequently prescribed medication in the study sample. When analyzing according to the first level of the ATC classification, the largest percentage of prescriptions fell on group R - "Respiratory system". From the sample studied by us, most often children were prescribed drugs in liquid dosage forms, namely, drops for oral administration, in off-label prescriptions, for the most part, solid dosage forms (tablets) were found. It was found that in most cases drugs were prescribed outside the instructions for children aged 1 to 3 years - 39% of all off-label prescriptions. In our opinion, to improve the pharmaceutical care provided to children, it is necessary to create a Russian indicative list of essential medicines for children, which should be periodically reviewed and republished in order to contain only relevant and reliable information.

The purpose of this study was to investigate the effectiveness of a multidimensional curriculum in improving the students' high-level thinking skills in middle and elementary schools. The method used was the experimental method with a quasi-experimental design by testing a multidimensional curriculum model integrated with scientific, creative, and future thinking competencies in the experimental group and comparing it to the control group. The participants involved in this study were 500 students divided into two groups, namely the experimental and control. The experimental group consisted of 250 students with a composition of elementary school (grades 4-6) and junior high school students (grades 9-12). The instrument used to measure the students' thinking skills was a questionnaire that contained three dimensions, namely scientific thinking, creative thinking, and future thinking. Data analysis was then carried out. First, factor analysis was used for the item scale analysis for each competency, the Pearson correlation to investigate the relationships between the competencies, paired sample tests to investigate the pre-test and post-test differences, and repeated tests to determine the results based on all variables. The results show that a multidimensional curriculum is proven to be effective at increasing the high-level thinking skills of elementary and middle school students. The improvement in higher-order thinking skills at the junior high school level is more significant than that of the elementary school students because the development of high-level thinking skills are by then sufficiently trained to think scientifically, creatively, and for the future compared to elementary school students. The dimensions of ability that have the most significant improvement are the ability to think about the future and the dimensions of the ability to think creatively. The strongest correlation between higher-order thinking skills and curriculum dimension elements was found in the correlation between creative thinking (identifying and solving problems). This research has the implication that the multidimensional curriculum in its implementation must be accompanied by the use of learning methods that are able to encourage students to think scientifically, creatively, and be able to predict the future.

Sanayileşme, modernleşme ve küreselleşme akımı ile hızlanan kentleşme oranı, yeni ihtiyaçlar ortaya çıkartmıştır. Bu durum üretim ile tüketim miktarını arttırdığından hem atmosferde sera gazları birikmiş hem de doğal kaynaklar tüketilmiştir. Gittikçe ısınan ekosistem, küresel ısınmaya yol açtığından iklimsel değişimler başlamış ve sürdürülebilirlik kavramı önem kazanmıştır. Nitekim geleneksel yerleşimler ve bu yerleşimlerde konumlanan yapılar, yerel malzeme kullanılarak topoğrafyaya ve iklime uyumlu inşa edildiklerinden söz konusu kavramı taşıyan en değerli örnekler arasında yer almaktadır. Böylelikle enerji korunumları yüksek olmuştur. Ayrıca toplumların geçmişleri hakkında bilgiler içeren ve tüm insanlığın evrensel değeri olan birer kültürel miras niteliğindedirler. Bu bağlamda geçmiş ile gelecek arasında köprü kurmaktadırlar. Ancak iklim değişikliği karşısında tahribata uğrayacakları ve enerji korunumlarının risk teşkil edeceği öngörülmektedir. Dolayısıyla doğru bir biçimde muhafaza edilmeleri önem arz etmektedir. Bu çalışmanın amacı Türkiye ve İtalya’dan seçilen UNESCO Dünya Miras Listesi ile Dünya Miras Geçici Listesi’ne alınan kültürel mirasların iklim değişimi bağlamında sürdürülebilirliklerini ve enerji korunumlarını irdelemektir. Çalışma boyunca kapsamlı bir literatür taraması yapıldıktan sonra Sassi di Matera, Ferrara, Siena, Safranbolu, Cumalıkızık ve Mardin tarihi yerleşimlerinin iklim değişikliği karşısında sürdürülebilirlikleri ile enerji korunumları analiz edilmiştir.

Bu çalışmada doğrusal regresyon analizinin varsayımlarının sağlanmadığı durumlarda kullanılabilecek olan kantil regresyon analizi ile Türkiyede 2000-2020 yılları arasındaki CO2 emisyonu ve birincil enerji tüketimi arasındaki ilişkinin modellenmesi amaçlanmıştır. Çalımanın ilk böümünde uygun regresyon modeli elde edildikten sonra, veri setine aykırı değerler eklenerek bu gözlemlerin varlığında sonuçlar yeniden elde edilmiş ve kantil regresyonun performansı değerlendirilmiştir. Uygun modelin seçiminde hata kareler ortalamasının karekökü (RMSE) ve ortalama mutlak hata (MAE) kriterleri kullanılmıştır. Elde edilen sonuçlara göre; Türkiye’de 2000-2020 yılları arasında ortalama CO2 emisyonu 289.62±68.12 milyon ton ve ortalama birincil enerji tüketimi 4.66±1.21 exajoule olarak belirlenmiştir. CO2 emisyonundaki değişimin %98.74’nün birincil enerji tüketimi ile açıklandığı ve değişen varyans probleminin varlığında kantil regresyon analizinin, doğrusal regresyon analizinden daha güvenilir sonuçlar verdiği elde edilmiştir. Kantil regresyon modeline göre; birincil enerji tüketimindeki bir exajoule’luk artışın CO2 emisyonunun τ=0.50. kantilinde yaklaşık olarak 54.3 milyon ton artışa sebep olacağı belirlenmiştir. Aykırı değerlerin varlığında τ=0.25 ve τ=0.50 için elde edilen kantil regresyon modelleri en uygun modeller olup birbirine oldukça yakın sonuçlar vermiştir. Bu modellerin, CO2 emisyonu ve birincil enerji tüketimi arasındaki ilişkinin modellenmesinde çıkarsama amaçlı kullanılması önerilmektedir.

Çalışmamızda, pamuk ve elyaf gibi ürünlerin boyanmasında kullanılan bir boyar madde olan asit blue 25’in atık sulardan Çaldıran/Diatomit ile bertaraf edilmesi incelenmiştir. Çalışmada derişimin (40 ppm, 80 ppm ve 120 ppm) ve sıcaklığın (293 K, 308 K ve 323 K) etkinliği de araştırılmış, elde edilen veriler Langmuir, Freundlich, D-R izoterm modellerine uygulanmıştır. Çalışma neticesinde hesaplanan izoterm hesaplamaları bizlere çalışmamızın Freundlich izoterm modeline daha iyi uyum sağladığını ve bu izoterme ait korelasyon katsayılarının tüm sıcaklıklarda 0.99’den büyük olduğunu göstermiştir. Paralel bir şekilde D-R izoterm modeli yardımıyla hesaplanan D-R adsorpsiyon serbest enerjisi ise tüm sıcaklıklar için 8 kJ/mol değerinden küçük bulunmuştur. Termodinamik hesaplamalar yardımıyla bulunan Gibbs serbest enerji değerlerinin negatif olması, adsorpsiyon işleminin kendiliğinden meydana geldiğini göstermiştir.

Tuz Stresinin Bitkiler Üzerindeki Etkileri ve Geliştirilen Tolerans Mekanizmaları
Authors: SEVGİ Büşra , LEBLEBİCİ Sema
Published: July 2023

Jeolojik, hidrolojik ve antropojenik birçok faktörün neden olduğu tuz stresi, bitkilerin hemen hemen tüm gelişme dönemlerinde olumsuz etkilere sebep olan oldukça karmaşık bir abiyotik strestir. Tuz stresinin neden olduğu ozmotik stres, bitki hücresindeki iyonik dengeyi ve genel homeostazı bozar. Bu abiyotik stres, osmotik strese neden olarak bitkilerin kullanabileceği su miktarını kısıtladığı gibi, iyonik stresi de tetikleyerek bitkilerde iyon miktarının toksik seviyelere ulaşmasına neden olmaktadır. Ayrıca bitkilerde reaktif oksijen türlerinin (ROT) artışını tetikleyen ikincil bir oksidatif stres oluşumuna neden olmaktadır. Genel olarak tuz stresine maruz kalan bitkilerde turgor kaybı, stoma iletkenliği ve fotosentez hızında azalma, besin dengesizliği, biyokütlenin azalması ve büyümenin yavaşlaması yaygın etkiler arasında görülür. Bitkiler bu olumsuz etkilerle baş edebilmek ve tuza tolerans oluşturabilmek için tuz alımı ve iyon taşınmasının kontrolü, ozmolitlerin ve antioksidanların sentezi veya birikimini içeren çeşitli savunma mekanizmaları geliştirmişlerdir. Farklı bitkiler, genotipe, adaptasyon kabiliyetine ve bitkinin diğer özelliklerine bağlı olarak tuzluluğa farklı tepkiler vermektedir. Endüstrileşmenin ve insan faaliyetlerinin hızla arttığı küreselleşen dünyada tuzluluğa dayanıklı transgenik bitkilerin geliştirilmesi verimliliği ve ürün kalitesi daha yüksek bitkiler elde etmek için oldukça önemlidir. Yüksek tuz konsantrasyonlarında yaşamlarını sürdürebilen halofitler ise, istenilen gen kaynağının sağlaması açısından tuza toleranslı glikofit bitkilerin yetiştirildiği çoğu transgenik çalışmada model organizmalar olarak kullanılmaktadır.

A new alternative approach has been suggested for evaluating the heat capacities of stannous selenide (SnSe), based on the Einstein-Debye approximation. It is well known the thermal behavior of solids is a very important theoretical problem that has been explored thoroughly with the development of Einstein, Debye and recently developed Einstein-Debye approximations. Many additional thermophysical characteristics of materials may be analyzed using the Einstein-Debye approach employed in this study. As an application, the heat capacities have been computed by using the Einstein-Debye method for SnSe in the temperatures range between 40 and 900 K. The temperature dependence of heat capacities have been computed and found to be in good accord with the literature throughout a wide temperature range.

Among these cereals, barley is an important cereal used in human and animal nutrition, and the most widelycultivated plant after wheat. There are biotic and abiotic factors which affect the yield and quality parameters of barley. Of the biotic factors, barley leaf stripe (agent: Pyrenophora graminea (anamorph: Drechslera graminea) is an important fungal disease. Infections can occur in diseased seeds and in the presence of suitable environmental conditions. Hence, the use of disease-free seeds and resistant cultivars (cvs.) against this pathogen are crucial. With this in mind, this study was carried out with a highly virulent isolate of Pyrenophora graminea, obtained from the Disease and Pest Resistance Unit culture collection in 57 registered barley cultivars in the greenhouses of the Central Research Institute of Field Crops (TARM) in 2021. The experiments were conducted in 3 replications in a randomized block design. Of 57 registered barley cultivars 62%, 15% and 36% of these barley cultivars expressed resistance, moderate resistance, and susceptible reactions, respectively. As a result of the analysis of variance performed on the results obtained, it was concluded that the difference between the mean values of 57 varieties was statistically significant at 1% level (P

This study was conducted during the 2017 and 2018 growing seasons to determine the yield performances, phenological and pomological characteristics of ten 21-year-old loquat cultivars grown under Mediterranean conditions at Dörtyol, Hatay, Turkey. The flowering of the cultivars was observed in detail and the earliest flowering was found in ‘Akko XIII’ and the latest in ‘Ottaviani’ cultivars. Among the tested cultivars, the highest yield was found in ‘Champion’ (168 kg tree-1, 387.36 g cm-2) whereas the earliest and latest ripening cultivars were found as ‘Akko XIII’ and ‘Lapta M’, respectively. The highest values in terms of fruit weight, seed weight and seed number were obtained from ‘Baduna 5’ variety as 50.60 g, 9.59 g and 4.50 fruits, respectively. In terms of fruit flesh/seed ratio, ‘Hafif Çukurgöbek’ (5.33) had the highest value, while ‘Lapta M’ (3.29) had the lowest. The highest total soluble solids, pH and acidity values were measured in ‘Hafif Çukurgöbek’ (13.70%), ‘Lapta B2’ (3.85) and ‘Lapta M’ (1.15), respectively. The cultivars used in the study were compared using the Weighted-Rankit Method according to their important characteristics and the cultivar ‘Hafif Cukurgöbek’ got the highest score. However, the results showed that most of the cultivars used in the experiment, except ‘Lapta M’, could be grown economically in the Mediterranean climate.

This research evaluates a semi-automatic incubator designed for hatching quail eggs using locally available materials, with the aim of increasing the quail population, since quails do not naturally incubate their eggs. The objective is to produce meat that competes with broilers as a rich source of protein. The study includes three experimental variables: three incubation temperatures (37, 37.5, and 37.7°C), three turning times (2, 6, and 12 times per day), and three post-hatching periods for chicks to remain in the incubator (2, 6, and 12 hours). The measurements include the percentage of total hatchability within the first 3 hours, as well as rates of deformation and mortality. The results of this research indicated that the manufactured semi-automatic incubator was able to maintain a high hatching percentage, low deformation percentage, and a low mortality percentage when using an incubation temperature of 37.5°C, turning the eggs 12 times per day, and allowing the chicks to stay in the incubator for 12 hours after hatching. Therefore, it is recommended to utilize the manufactured semi-automatic incubator for hatching quail eggs under the above-mentioned parameters.

Ölüm, ayrılık, doğal afetler ve savaş gibi olaylar insanlığın ortak acılarını yansıtır. Bu acılara verilen tepkiler toplumdan topluma, kültürden kültüre değişkenlik gösterdiği gibi aynı toplumda yöreden yöreye de farklılık arz etmektedir.
İnsanları acıya, hüzne, kedere gark eden söz konusu vakalar sonucu yakılan ağıtların Türk kültüründe köklü bir geçmişi vardır. Edebiyatımızın ninni, mani, tekerleme, efsane, destan, hikâye ve masal gibi sözlü kültürlerinin diğer
bir halkası da ağıtlardır. Türk insanı, bu dayanılmaz acılar karşısında çaresizliğini “ağlama” eylemiyle bir nevi müzikal bir havaya büründürerek “ağıt yakma, ağıt düzme, ağıt etme, ağıt söyleme” diye tarif edilen şiirlerle terennüm
ederek dile getirmiştir. Genel olarak ölen kimsenin ardından söylenen şiirler olarak bilinen ağıtlar, ağlamayı meşrulaştıran deprem, yangın, sel, savaş, ayrılık, askere gitme ve gelin gitme gibi hadiseleri de kapsamaktadır. Bu
çalışmada, Sivas Elbeyli yöresi Güney köyünde ağıt yakma geleneğine bağlı olarak icra edilen ağıtlara yer verilmiştir. Güney Köyü Ferdî Halk Edebiyatı Ürünleri adlı yüksek lisans tezinden türetilen çalışmada “Ağıt Yakma Geleneği
ve Sivas Güney Köyü Ağıtları” bölümü üç alt başlıkta sınıflandırılmıştır. Erkek ağıtçılara ait on beş, kadın ağıtçılara ait yirmi ve altı adet de anonim ağıt bulunmaktadır. Genel kabul doğrultusunda çalışmada, kadınların yakmış
oldukları ağıtlar çoğunluktadır. Ağıtların büyük bölümü belli kişiler tarafından söylenmiştir. Ağıtlar, hikâyeli şiirlerdir. Bu hikâyeler; yöreye ait bilgiler, coğrafî özellikler, sosyal yapı, kişiler hakkında bilgi, kültürel birikimin
aktarılması gibi işleve sahiptir. Genel olarak ölüm ve ayrılık üzerine yakılan bu ağıtların hikâyesi tespit edilenlerin hikâyelerine yer verilmiştir.
