Authors: Tyazhelov Olexiy , Khasawneh Ayham Adli Mohammad , Karpinska Olena , Karpinsky Mykhaylo , Bitsadze Marianna
Published: June 2023

Disruption of joint mobility (contracture) is a frequent consequence of the treatment of injuries or orthopedic diseases, when the method of immobilization is used in the treatment process. One of the physiotherapeutic methods of preventing contractures and restoring joint mobility after long-term immobilization is vibration therapy. Objective. Create a concept of the effect of low-frequency vibration on joints and peri-articular tissues after immobilization. Methods. The work was performed using a meta-analysis of literature sourcesfrom scientific databases. The publications were analyzed, which considered the impact of vibration on joints or had data on its biologicalimpact on body tissues. Results. The physiological impact of vibration on the body is based on mechanical, physico-chemical and thermal effects. The expression of the physiological response depends on the frequency and amplitude of oscillations, conditions of conducting and localization. The concept is based on the features of the impact of vibration on the structural elements of limbs and joints. The vibration applied to the limb irritates mechanoreceptors,  which send a signal to the central nervous system, and thanks to motoneurons, muscle contraction occurs, which affects peripheral blood flow and blood oxygenation. Accordingly, redox processes in tissues are launched. Micromovements caused by vibration contribute to the nutrition of cartilage and metabolism in the synovial fluid, improving the nutrition of periarticular tissues. This contributes to the recovery of both joint and adjacent tissues. Contraction of muscles through motoneurons gives impetus to a gradual increase in their motor activity and strength, restoration of nutrition and cartilage surface - to restoration of mobility. Conclusions. The created conceptual model of the effect of low-frequency vibration on joints with limited mobility due to immobilization takes into account tissue changes under its influence. The concept involves restoration of nutrition of tissues and muscles adjacent to the joint. It is vibration, due to the possibility of transmitting vibrational energy between tissues, that enables the processes of muscle contraction, which increase the blood supply and metabolism of the joint.

Published: June 2023

Bone pathology begins in the early stages of chronic kidney disease (CKD), but clinical consequences — bone pain and fractures — occur mainly at stage 5 of the disease (VD) in patients who use methods renal replacement therapy. Objective. To find out the frequency, localization and possible predictors of fractures in patients with CKD VD stage on the background of hemodialysis according to the results of a prospective study. Methods. 254 patientswere included in the cohort prospective open study with CKD VD stage, which was treated with hemodialysis hemodialysis during 2018‒2022. The study was conducted in two stages. On the first, based on the analysis of medical documentation, received data on the presence of fractures of all localizations, diabetes, hypertension, secondary hyperparathyroidism, hyperhydration, type of initial vascular access, eKt/V, body mass index (IMT), peripheral vasculardisease. At the second stage, a prospective study of new cases of fractures was conducted. Results. Examined72 (32.3 %) women and 151 (67.7 %) men, average age — (49.4 ± 14.03) years — did not differ significantly depending on gender (p = 0.1088). The most frequent cause of CKD stage VD was glomerulonephritis — 111 patients (49.77 %). At the time of the beginning of observation, 30 cases were ascertained fractures in 26 patients, and at the end — 62 in 51 patients. By the results of univariate Cox regression analysis it was established that independent predictors of occurrence new fractures are the patientʼs age, female gender, smoking, presence of peripheral vascular diseases, BMI, as well as serum albumin, parathyroid hormone, calcium, phosphorus, alkaline phosphatase, and vitamin D levels. Conclusions. The developed method of fracture risk assessment for patients with CKD VD stage on the background of hemodialysis is individualized, accessible in execution and interpretation, allows to distinguish patients with increased risk the occurrence of fractures with the help of standard bases clinical and laboratory indicators.
BONE REGENERATION AFTER IMPLANTATION OF CALCIUM PHOSPHATE CEMENTS BASED ON METASTABLE TRICALCIUM PHOSPHATE (IN VIVO EXPERIMENTAL STUDY)
Authors: Poplavska Karolina , Ashukina Nataliya
Published: June 2023

Calcium phosphatCalcium phosphate cement (CPC) is a material used to fill bone defects. Its advantages include being able to fill irregularly shaped spaces, its similarity to bone tissue, and ease of biodegradation. However, insufficient durability and unpredictable rate of resorption limit CPC use. Objective. Study the dynamics of morphological changes in rat femurs after implanting two types of CPC based on metastable αʹ‒tricalcium phosphate(αʹ‒TCP) into defects in the distal metaphysis. Methods. 42 male white rats were used in the study. In each rat, defects were created in the distal metaphysis of the left femur and filled with one of the two types of CPC. The animals were split into two groups: І (n = 21) — CPC based on αʹ‒TCP powder; ІІ (n = 21) — CPС based on αʹ‒TCP powder reinforced with hydroxyapatite (HA) whiskers (4 % mass). Both varieties of CPC were developed and prepared at the Department of Solid-State Physics at the V. N. Karazin Kharkiv National University (Ukraine). 14, 30, and 60 days after the surgery, the animals were sacrificed, and histological analyses were performed. Results. For both types of CPC, inflammation was not observed in the region around the implant at 14, 30, or at 60 days. Bone tissue formed on the surface of the materials. The stages of bone repair were similar to the known stages of bone repair. As a result of the resorption of the CPC, 60 days after surgery the CPC comprised 26.83 % of the area of the defect in group I and 29.93 % in group II. The rest of the area was composed of lamellar bone. The two groups did not differ significantly in rate of CPC resorption or bone tissue formation. Conclusions. The two types of CPC studied, based on αʹ‒TCP (group I) and αʹ‒TCP reinforced with HA whiskers (group II), are biocompatible, osteoconductive, and osteoinductive. In addition, these materials are biodegradable and, with time, are replaced by bone tissue.

Published: June 2023

Large joint damage often leads to inability to work and disability that requires long-term treatment. The development of osteoarthritis is accompanied by changes in the muscles and special rehabilitation measures are needed to restore their strength, symmetry of the load during standing and steps during walking. Objective. To determine the most vulnerable muscles of the lower extremities in the conditions of osteoarthritis of the hip and knee joints using a mathematical model. Methods. Three mathematical models were created in the OpenSim system. Model 1 (normal): extension/flexion — 10°/0°/45°; removal/adduction — 5°/0°/12°; rotation — 3°/0°/3°, foot turning — 5°. Model 2 with flexion-adduction contracture of the hip: flexion setup — 20°,adduction setting — 10°, foot turning — 10°, shortening of the femur by 2 cm. Model 3: flexion contracture of the knee joint — 0/20°/50°. Results. With combined hip contracture, the isometric strength of the muscles decreases by almost 60 %. In the case of flexion contracture of the knee joint, the rectus femoris muscle is more stretched and requires 3.5 % more force to extend the knee. In the presence of adductor contracture of the hip joint,the thigh's thin muscle is in a contractile state, which reduces its strength by almost 90 %. In the case of knee contracture, this muscle is primarily in a stretched state, so more force is required to extend the knee — in our model, by 6 %. With changes in the lower extremity due to the development of hip contracture, the gastrocnemius muscle can lose up to 78 % of its strength, and the knee muscle — up to 5%. In conditions of knee joint contracture,the most vulnerable muscles are the pelvic stabilizer muscles (m. tensor fasciae latae) — a decrease in strength of up to 44.4 %, and the knee (m. semimembranosus) — up to 54.5 %. Conclusions. Contractures of the hip and knee joints lead to a loss of muscle strength of the lower limb, which negatively affects its functioning and recovery after arthroplasty.

De influencer a primera dama: Mariana Rodríguez en las elecciones a la gubernatura de Nuevo León, México 2021
Authors: Álvarez-Monsiváis Edrei , Marañón Felipe
Published: June 2023

Se realizó un análisis de contenido, de corte cuantitativo, sobre las publicaciones en Instagram de la influencer Mariana Rodríguez, esposa del candidato a la gubernatura, Samuel García, durante las elecciones de Nuevo León en 2021. El estudio se guía en tres preguntas referente a los elementos que lograron un mayor engagement (cantidad de likes y comentarios), el rol del perfil de Instagram de Rodríguez durante la campaña y qué encuadre político fue utilizado en mayor medida. Los resultados demuestran una tendencia hacia el encuadre de escolta (M=.58), al registrar fotos y videos de Mariana en los que aparece a un lado de su esposo y usando los logos y eslóganes de campaña; mientras que el encuadre político de juego estratégico fue el más reiterado (M=.59), al indicar la viabilidad de campaña sin emitir propuestas. Se concluye que el perfil de Instagram sirvió como una estrategia de campaña que buscó humanizar a Samuel a partir de auto representar a Mariana desde su roles tradicionales de esposa. Lo anterior en detrimento de fomentar un espacio deliberativo con propuestas de campaña que permitiera a sus seguidores decidir la dirección de su voto.
"I think women can do anything": Postfeminist Sensibilities and the Male Gaze in Charlie's Angels (2019).
Authors: Van Belle Jono , Lietaert Jasmine , Joye Stijn
Published: June 2023

This article considers Mulvey's male gaze in today's postfeminist media culture in the latest remake of Charlie's Angels. Male gaze is analyzed as form, as production ecology, and as narrative. Since the inception of Charlie's Angels in the 1970s, the TV and feature film franchise has tried to balance feminist concerns with notions of femininity, in more and less successful ways. Although the 2000 remake of Charlie's Angels could be considered as an exemplar of objectifying and sexualizing women, the 2019 film barely presents such instances. Instead, it offers a male gaze directed at a female audience and internalized as a measure of success for its female protagonists and the implied female audience. Through practices of othering, and by placing male characters in morally inferior positions, the female audience is presented with hegemonic conceptions of white, middle-class femininity as an ideal that female viewers can and should aspire to be.

Published: June 2023

Bu çalışmanın amacı, dönem içinde kaydedilen alacak karşılıklarının kazanç yönetimi için kullanılıp kullanılmadığını araştırmaktır. Muhasebe standartlarının, özellikle 2018 yılında TFRS 9’un yürürlüğe girmesiyle, yöneticilere sağladığı takdir alanını genişletmesi, alacak karşılıklarının araştırılmasının en önemli gerekçesidir. Bu çalışmada, kazanç yönetimi davranışlarını alacak karşılıkları üzerinden incelemek için ampirik literatüre yön veren ilk önemli araştırma olan McNichols & Wilson çalışmasında geliştirilen modeli referans alan modifiye bir model kurgulanmıştır. Çalışmada referans model ve modifiye model, panel veri analizinde havuzlanmış en küçük kareler ve sabit etkiler regresyon modelleriyle test edilmiştir. Modellerin çıktıları benzer ve her ikisi de anlamlı olmasına rağmen, modifiye modelin açıklayıcılık düzeyi daha yüksektir. Her iki modelin çıktısı, endeks dışı borsa şirketleri ve denetim raporunda olumlu görüş almayan şirketler için kazanç yönetimini ima eden değerlerin daha yüksek olduğuna işaret eder. Betimleyici analizler bu sonucu doğrulamaktadır. Bu çalışma, Borsa İstanbul özelinde kazanç yönetimini alacak karşılıkları üzerinden inceleyen ilk modelleme çalışmasıdır. Bu çalışmada sunulan model, alacak karşılıklarındaki aşırılıkları daha geniş çerçevede ele alan değişkenlerle araştıracak çalışmalara bir çerçeve oluşturmaktadır.
A Study on the Symbolic Meanings of “Travel to a Different Underwater World” and “Fish Wife” in a Mongolian Oral Folktale－With a focus on The Young Man, The Dreamer－
Authors:   The Korean Association for Mongolian Studies, LEE AN NA
Published: June 2023

Folktales have long been transmitted, embodying the life issues and wishes of people in interesting symbols and reflecting the fundamental collective unconsciousness of the human mind. This study set out to investigate the inner world of the main character’s ego and examine his journey of finding his “self” deep in his unconsciousness in The Young Man, The Dreamer, which is a folktale whose storytelling unit is a dream. There is a young man made by the king to dream a dream for the king’s greater desire. One night, he dreams of becoming a king himself and is banished to a distant sea, where he saves a fish, travels a different world at the underwater palace of the Dragon King, and takes the fish as his wife, thus realizing his dream of becoming a king himself. Here, the man on a white horse that brings the young man to the underwater palace represents the inner “spirit”(Geist) of the main character that guides him. The underwater world represents his unconsciousness. The fish lady, who is the yellow dog brought from the underwater world, represents “anima,” which is the female character of his unconsciousness. The Dragon King at the underwater palace represents the archetypical image of his “self”. The king that puts the young man in hardship represents the “negative father image” inside the main character. Taboos or prohibited matters in this kind of tales have an attribute of being broken, which expands an event and prolongs time for the main character’s maturity while training the inside of the main character and assisting him with his complete self-growth. The narrative of this folktale shows the process of the dreaming young man living in a deficient mundane world opening up his unconsciousness through dreams and seas and tells a story of finding his anima and exploring his “self” as the transcendent center of his spirit.

Bu makalede Mağrib coğrafyası muhaddislerinden Kâbisî’nin (ö. 403/1012) Mâlik b. Enes’in (ö. 179/795) Muvatta’ının İbnü’l-Kâsım rivâyetindeki muttasıl senedleri bir araya getirmek üzere kaleme aldığı Kitâbü Mülahhısi’l-Muvatta’ eserine yazmış olduğu mukaddime ele alınmaktadır. Söz konusu mukaddimede müellif Kitâbü Mülahhısi’l-Muvatta’ın telif amacı ve eserde izlediği yöntemi belirtmesinin yanı sıra bazı hadis usûlü meselelerine yer vermiştir. Onun bu kısımda ele aldığı hadis usûlü kavramlarının ve konularının tespit edilmesi çalışmanın ana gayesini oluşturmaktadır. Bu bağlamda önce Kâbisî’nin hayatı ve ilim tahsîlinden söz edilmiş, ardından bahse konu olan eserinin özelliklerine ilişkin birtakım bilgiler sunulmuştur. Sonrasında onun eserinin mukaddimesinde değindiği hadis usûlü kavramları ve bu konulara yönelik açıklamaları ayrı başlıklar altında incelenmiştir. Meşrik rıhlesi dönüşünde Mağrib’in Doğu literatürüne ait bazı hadis eserleri ile tanışmasına öncülük eden Kâbisî’nin hadis usûlü bağlamındaki görüşlerinden istifâde edip ona referansta bulunan Endülüs bölgesi âlimleri tespit edilmeye çalışılmıştır. Ayrıca Kâbisî’nin hadis usûlü ile ilgili bahsettiği konularda Mâlik’in yaklaşımlarını benimsediği ve ona atıfla meseleleri izaha yöneldiği kısımlar ve Mâlik’ten farklılaştığı hususlar zikredilmiştir.

Objective

Acute appendicitis is the most common cause of nonobstetric

acute abdomen in pregnant women. The

fact that sympathomatology brings to mind primarily

obstetric causes in pregnant patients, physiological

leukocytosis is observed throughout pregnancy, and

limitations in imaging methods cause confusion in the

diagnosis. This makes the need for detailed evaluation

in laboratory parameters inevitable. The aim of

the study is to reveal the relationship of laboratory

parameters such as neutrophil lymphocyte ratio

(NLR), platelet lymphocyte ratio (PLR), lymphopenia

with the diagnosis of appendicitis and its diagnostic

power.

Material and Method

In the evaluation of 31 patients who were operated

on with the diagnosis of acute appendicitis during

pregnancy between January 2017 and February

2021 were evaluated. Correlation and roc analysis

were performed by evaluating patients' demographic

data, laboratory results, ultrasonography or magnetic

resonance imaging reports and intraoperative

findings.

Results

A significant correlation was found between

detection of appendicitis in exploration and increased

neutrophils, leukocytosis, and NLR (p: 0.014, p:

0.015, p: 0.020, respectively). Again, the presence

of lymphopenia, high NLR and increased palletelet /

lymphocyte ratio (PLR) were found to be associated

with prolonged hospitalization (p:0.037, p:0.008, and

p:0.024, respectively). Roc analysis also showed that

leukocytosis [AUC: 0.938 (95%CI: 0-1.00, p:0.019)],

neutrophil elevation [AUC: 0.938 (95%CI: 0-1.00,

p:0.019)] and NLR [AUC: 0.917 (0-1.00 p: 0.025)]

was found to have the power to reveal the presence

of significant acute appendicitis.

Conclusion

It is recommended to use hemogram parameters and

imaging methods effectively in the diagnosis of acute

appendicitis in pregnants.

RİFAMPİSİN KAYNAKLI BEYİN DOKUSU HASARINDA LİNALOOL’UN İYİLEŞTİRİCİ RÖLÜ
Authors: ÖZGÖÇMEN Meltem , AZIRAK Sebile
Published: June 2023

Objective

In this study linalool (LN), which has antihyperglycemic,

hypolipidemic and antioxidant properties, is intended

to be used in the treatment of neurodegenerations

and neural disorders that may occur due to rifampicin

(RF). For this reason, it was aimed to examine the

effects of LN on the expression of genes, biochemical

and histopathological parameters in these metabolic

pathways against neurotoxicity that may occur due

to RF, and to investigate the protective effects of LN,

which has antioxidant properties.

Material and Method

Thirty healthy male Spraque-Dawley rats were divided

into five groups (group 1; control, group 2; solvent

control (DMSO); group 3, RF; group 4, LN; group 5;

RF+LN). Brain tissues were taken for biochemical,

histological and gene expressions analyses. Blood

samples were taken to measure blood glucose levels.

Results

Rifampicin treatment significantly increased CYP1A1

and CYP1A2 mRNA gene expression and blood

glucose levels, while reducing brain weight according

to findings. On the other hand, there was a significant

decrease in CYP1A1 and CYP1A2 mRNA gene

expression and blood glucose levels in the RF+LN

group, while a significant improvement in brain weight

was observed and as a result of histological analyzes,

it was observed that the damage caused by RF

decreased in the groups given LN.

Conclusion

LN was found to be highly effective in protecting the

brain from the toxic effects of RF.

Traditional Chinese Medicine (TCM) is widely used in health preservation and non-radical treatment because of its relatively gentle therapeutic effect, which is reflected in many products. Especially in atomization therapy, TCM shows its strong potential. This experiment focused on analyzing the extract of green tea (tea polyphenols) in a nebulizer, which is very similar to e-cigarettes. After intravenous injection of relevant drugs into small experimental pigs, the results of blood tests and the HE staining of organ sections showed no abnormalities in the experimental group. Since the dose of intravenous injection is much larger than that of nebulized inhalation, the safety of the product was verified by the experiment. The relevant analysis results obtained in this experiment will be used for comparison with subsequent, longer-term (more than 3 months) injection experiments.
МОРАЛЬНАЯ ДЕГРАДАЦИЯ РУССКОГО ДВОРЯНСТВА XIX ВЕКА В КОМЕДИИ «СВАДЬБА КРЕЧИНСКОГО» А. В. СУХОВО-КОБЫЛИНА
Authors: ILICA Sevgi
Published: June 2023

В русской литературе XIX века было множество разнообразных идей и мнений, отражающих мнения и взгляды различных групп и людей. Некоторые из этих идей были уникальными и глубокими, в то время как другие были типичными для того времени. Хотя интерес к политической роли аристократии уже не был настолько популярным, как раньше, интерес к истории и значимости высших слоев дворянства сохранялся. Некоторые интеллигентные люди начали задумываться о исторических судьбах этих слоев и их значимости в прошлом, что сделало эту тему более актуальной для обсуждения и исследования. Русский драматург Александр Васильевич Сухово-Кобылин (1817-1903) отличется от многих других писателей своего времени, которые критиковали дворянскую культуру и традиции за ее роскошь и отсталость. Сухово-Кобылин видит в этой культуре не только недостатки, но и ценности, которые следует сохранять и развивать. Он считает, что высшее общество должно играть важную роль в развитии культуры и образования, и что дворянская культура и традиции могут дать важный вклад в этом процессе. В России в тот период происходили культурные изменения, которые включали в себя рост городской культуры, образования и науки, а также изменения в общественном мнении и ценностях. В своей комедии "Свадьба Кречинского" Сухово-Кобылин отразил эту моральную деградацию и выразил свои мнения и взгляды на это явление. Цель исследования заключается в анализе комедии «Свадьба Кречинского» русского драматурга Сухово-Кобылина и выявлении мнений и взглядов автора на дворянство того времени. Для достижения этой цели используется историко-литературный метод анализа художественного текста, который позволяет понять, как произведение отражает эпоху и общество, в которых оно было создано.
Cloning by Gibson Assembly v1
Authors: Cordeiro-Spinetti Eric
Published: June 2023

Gibson assembly is a molecular cloning method that allows for the joining of multiple DNA fragments in a single, isothermal reaction. It is named after its creator, Daniel G. Gibson, who is the chief technology officer and co-founder of the synthetic biology company, Telesis Bio. - Wikipedia Daniel G. Gibson, of the J. Craig Venter Institute, described a robust exonuclease-based method to assemble DNA seamlessly and in the correct order, eponymously known as Gibson Assembly. The reaction is carried out under isothermal conditions using three enzymatic activities: a 5’ exonuclease generates long overhangs, a polymerase fills in the gaps of the annealed single strand regions, and a DNA ligase seals the nicks of the annealed and filled-in gaps. This method has been widely adopted and is a major workhorse of synthetic biology projects worldwide.

Published: June 2023

Geçmişten günümüze kadar mikro ve makro boyutta pek çok ekonomik buhran meydana gelmiştir. Finansal krizlerin sayısı çoğaldıkça ve etkisi derinleştikçe iktisatçılar ve hükümetler ortak paydada birleşip krizleri öngörülebilir kılmaya çalışmışlar ve çok önemli sonuçlar elde etmişlerdir. Günümüze gelindiğinde de krizler öngörülebilir hale getirilmiştir. Buradan yola çıkarak finansal krizler incelenmiş sebep-sonuç ilişkilerine odaklanılmıştır. Krizlerin gruplandırılması ve modellemeleri hakkında araştırmalar yapılmıştır. Öncü göstergeler indeksi açılımı yapılmış, etkisi ve başarısı irdelenmiştir. Öncü göstergeler indeksini etkileyen bağımsız değişkenler tespit edilmiş; bu değişkenlerin öncü göstergeler indeksine olan etkisi araştırılmış ve Türkiye modeli kurulmuştur. Çalışmanın amacı kriz dönemlerinin öncü göstergesi olan bileşik öncü göstergeler üzerinde etkili olduğu düşünülen PMI, API, BTI ve tüketici güven indekslerinin ilişkilerinin belirlenmesidir. Hem iş adamları görüşü hem tüketici görüşleri hem de finansal gidişatın durumu ile krizleri öncülemede ne denli başarılı olduğu belirlenmeye çalışılmıştır.
