Published: June 2023

Introducción: La enfermedad degenerativa de la columna lumbar es frecuente, pero aún existen dudas en relación con los criterios de inestabilidad.
Objetivos: Analizar la relación del signo del fluido facetario lumbar como criterio de inestabilidad vertebral segmentaria.
Materiales y Métodos: Pacientes con enfermedad lumbar crónica, que presentan hidrartrosis facetaria en la resonancia magnética y las radiografías de columna lumbar dinámicas. Se analizan la prevalencia del sexo, la edad, la sintomatología principal y el dolor a la extensión unilateral o bilateral.
Resultados: Se evaluó a 139 pacientes (62% mujeres), con un promedio de edad de 50.8 años; el principal motivo de consulta fue lumbalgia (76%). El 65% refería dolor en extensión; el 35%, dolor unilateral y el 30%, dolor bilateral. El 14% tenía espondilolistesis de bajo grado en L4-L5 y el 7%, en L5-S1. La hidrartrosis era unilateral en el 20% y bilateral en el 80%; el nivel de hidrartrosis más frecuente era en L4-L5 (58%). El 6% tenía solo inestabilidad traslacional y el 2%, mixta. Un 8% presentaba Modic I y un 5%, Modic II.
Conclusiones: La presencia de fluido facetario no es un criterio de inestabilidad vertebral segmentaria, al margen del nivel y el segmento localizado, o la presentación facetaria lumbar unilateral o bilateral.

Published: June 2023

Introducción: Los bloqueos facetarios intrarticulares y radiculares selectivos son útiles como método diagnóstico y terapéutico para el manejo del dolor lumbar crónico. El objetivo de este estudio fue describir y analizar los resultados de dichos bloqueos.
Materiales y Métodos: Se realizó un estudio de cohorte retrospectivo con datos de pacientes sometidos a bloqueos facetarios intrarticulares y radiculares selectivos guiados por tomografía computarizada, entre enero de 2014 y febrero de 2015. Se analizaron los datos demográficos, el puntaje en la escala analógica visual antes del bloqueo y después, y se analizó la asociación de estos factores con los resultados.
Resultados: El estudio incluyó a 68 pacientes con bloqueo facetario intrarticular y 89 con bloqueo radicular selectivo. En ambos grupos, el dolor mejoró significativamente (p <0,05). Hubo una asociación entre la mejoría del dolor con los bloqueos facetarios intrarticulares y el sexo y la edad, y entre la mejoría lograda por los bloqueos radiculares selectivos y el tipo de dolor inicial.
Conclusiones: Los bloqueos facetarios intrarticulares y los bloqueos radiculares selectivos son un métododiagnóstico útil en el manejo del dolor lumbar crónico y su acción terapéutica es significativa, aunque hacen falta estudios para conocer su efecto analgésico a mediano y largo plazo, y así poder mejorar la calidad de vida de los pacientes.

Introducción: El uso del sistema de barras magnéticas para el tratamiento de la escoliosis de comienzo temprano es un método utilizado en los últimos 10 años; su eficacia está respaldada por la bibliografía, pero no está exento de complicaciones.

Objetivo: Analizar retrospectivamente una serie de 37 pacientes tratados con barras magnéticas en escoliosis de comienzo temprano.

Materiales y Métodos: Se realizó un estudio retrospectivo entre 2014 y 2019. Se dividió a los pacientes en: grupo 1 (procedimientos primarios con barras magnéticas) y grupo 2 (conversiones de sistema tradicional a barras magnéticas).

Resultados: Se incluyó a 19 niñas y 18 niños (edad promedio 8 años al operarse), las etiologías fueron variadas. Entre el grupo 1 (n = 28) y el grupo 2 (n = 9), el seguimiento promedio posoperatorio fue de 3.6 años. El valor angular promedio preoperatorio de escoliosis era de 64° (rango 39°-101°) y el de cifosis, de 51° (rango 7°-81°). El valor angular promedio de escoliosis en el posoperatorio inmediato fue de 41° (rango 17°-80°) y el de cifosis, de 34° (rango 7°-82°). Se produjeron 2 roturas de barra y una cifosis de unión proximal, 2 aflojamientos de tornillos proximales, una falla del sistema de distracción de barras magnéticas y una infección del sitio quirúrgico.

Conclusiones: Nuestros resultados preliminares, aunque son a corto plazo, sugieren que la barra magnética podría ser un método eficaz en este tipo de enfermedad.

Alteración de la marcha y poliartralgia como manifestación de escorbuto en un niño. Presentación de un caso
Authors: Girard María Florencia , Santana María Nella , Casaccio Bruno Gabriel
Published: June 2023

La vitamina C o ácido ascórbico es imprescindible para el correcto funcionamiento del organismo. Los seres humanos no pueden sintetizarla; en consecuencia, dependen estrictamente de su aporte exógeno. Su déficit causa escorbuto, un cuadro que se manifiesta con fatiga, mialgias y poliartralgias, hemorragias en la piel y sangrado de las encías. Es una enfermedad infrecuente. La mayoría de los casos publicados corresponden a niños con restricciones alimentarias por trastornos del neurodesarrollo. La respuesta satisfactoria al aporte de ácido ascórbico confirma el diagnóstico. La sospecha de esta enfermedad evitaría exámenescomplementarios innecesarios y el tratamiento temprano ayudaría a revertir los síntomas y prevenir complicaciones. Se presenta el caso de un varón de 13 años que consulta por dolor en ambas caderas con progresión hacia las rodillas, sumado a pérdida de la fuerza y hematomas en los miembros inferiores. El objetivo de esta presentación es resaltar la importancia de la anamnesis alimentaria completa y evitar un abordaje tardío con múltiples intervenciones.

Published: June 2023

Objetivo: Realizar una descripción anatómica de las estructuras involucradas en el abordaje para la técnica de abordaje lateral (fusión intersomática lateral extrema) basada en imágenes de resonancia magnética en decúbito dorsal.

Materiales y Métodos: Se llevó a cabo un estudio observacional, descriptivo, retrospectivo, de 200 pacientes evaluados con resonancia magnética de columna lumbosacra. Se tomaron mediciones en cortes axiales para determinar el posicionamiento de la vena cava, la arteria aorta, y el ancho y la altura del músculo psoas a fin de delimitar zonas de seguridad y de riesgo.

Resultados: La muestra final incluyó a 164 pacientes con una edad media de 50.4 años en los hombres y 50.6 años en las mujeres. La arteria aorta abdominal en su recorrido hasta el espacio L3-L4 se ubica predominantemente del lado izquierdo en la zona A y, al llegar al espacio L4-L5, en el 95,7% de los pacientes, se observó la bifurcación de las arterias ilíacas. La vena cava mostró una tendencia de localizaciónhacia el lado derecho y su bifurcación a nivel de L4-L5.

Conclusiones: La planificación preoperatoria y la delimitación de la zona segura representan un método sencillo para evaluar la posición relativa de las estructuras anatómicas neurales y vasculares en relación con el área quirúrgica. Este método puede ayudar a los cirujanos de columna a prevenir complicaciones perioperatorias.

Precise determination of Young’s modulus of amorphous CuZr/nanocrystalline Cu multilayer via nanoindentation
Authors: Lassnig Alice , Zak Stanislav
Published: June 2023

Extracting mechanical data of thin films on rigid substrates using nanoindentation is compromised by the mechanical properties of underlying substrates, which may falsify the obtained results. With ongoing miniaturization, the substrate influence becomes more pronounced. In this study we present an experimental approach to extract the true Young’s modulus of crystalline-amorphous multilayers by means of nanoindentation. We used 1 µm thick multilayers comprised of amorphous CuZr and nanocrystalline Cu. All films were deposited onto two rigid substrate types with Young’s moduli below and above the ones expected for the deposits (film-to-substrate hardness and elastic moduli ratios between 0.3 to 1.1 and 0.6 to 1.5, respectively). Linear extrapolation of indentation data to zero indentation depth allows to precisely determine the real film’s Young’s modulus. Same investigations were performed on monolithic Cu and CuZr films of same thickness. While the hardness values change with the variation of the bilayer thickness of the multilayer structures, the Young’s modulus is not affected by the interfaces.

Synthesis and characterization of polyurethane films based on castor oil-derived polyols with heparin and low-molecular-weight chitosan for cardiovascular implants
Authors: Uscátegui Maldonado Yomaira Lisnedy , Díaz Barrera Luis Eduardo , Valero Valdivieso Manuel Fernando , Coy-Barrera Ericsson
Published: June 2023

Applications of polyurethanes (PUs) depend on several physicochemical factors due to the presence of varied monomers involving several ratios. The present study aimed to synthesize various chitosan/heparin-inserted PUs to examine the addition effect on the mechanical and biological properties of the PU-based polymeric material. The PUs were synthesized from unmodified castor oil and isophorone diisocyanate, including chitosan and heparin as fillers. The FTIR, thermal, and mechanical characterization of materials with and without fillers exhibited properties that can be considered within the accepted values. In addition, considering the non-cytotoxicity and antibacterial activity, these synthesized polymers can be exploited as biomaterials. The results also showed that these PUs offer a competitive advantage over other materials since the observed good mechanical and biological properties were found to be within the optimal range for the biomaterial design to myocardial or vascular tissue engineering.

A 24-Hour Movement Behavior for Young Children in South Korea
Authors: Song Yoonkyung , Jeon Justin Y.
Published: June 2023

PURPOSE: This study aimed to investigate the 24-h movement behavior of young children in Korea and examine the associations of their physical activity (PA) and screen time (ST) with parental cognition and behavior in homes and neighborhood environments.METHODS: Participants included 164 young children (4.4±1.2 years; boys 42.1%) and their parents. Young children’s sleep, PA, ST, parental cognitions and behaviors, and home and neighborhood environment were measured via parental reports using the Parents’ Role in Establishing Healthy Physical Activity and Sedentary Behavior Habits Questionnaire. Two-tailed independent sample t-tests or Mann–Whitney U tests, and correlation analyses were performed.RESULTS: The average sleep time of toddlers was 9.8±0.8 h/day, the total time of PA was 72.1±40.0 min/day, and the ST was 87.6±70.5 min/day. The adherence rate to the guidelines for sleep, PA, and ST increased with age except for 2-year-olds, and PA was found to be significantly lower than the guidelines at each age. Parental support for their children was positively associated with young children’s PA (r=0.195, p<.01), and negative parental outcome expectations for limiting young children’s ST were associated with young children’s ST (r=0.275, p<.01).CONCLUSIONS: Young children in South Korea do not meet PA, ST, and sleep guidelines. Parental cognition may play an essential role in establishing young children’s behavior. These findings can inform family-based interventions to increase PA and minimize ST.

Authors: Kim Kitae , Kim Youngsook , Baek Donggyu , Park Jaebum , Song Junkyung
Published: June 2023

PURPOSE: This study examined the effect of anticipatory control strategies on stable upright posture and consistency in archery performance among skilled elite archers.METHODS: Nine skilled archery players participated in this study and performed repeated shooting trials under two different shooting conditions: clicker and non-clicker. In the clicker condition, archers shot in response to clicker signals, whereas in the non-clicker condition, they used an anticipatory strategy to determine shooting time in a self-paced manner without using the clicker. A motion capture system with six infrared cameras was used to measure the coordinates of the bow and archers’ hands, which were then used to calculate the aiming precision index and draw-related variables. Electromyography of the lower leg muscles and the center of pressure (COP) were also analyzed for a short period immediately before release to determine the differences in anticipatory postural adjustments (APAs) between the two shooting conditions.RESULTS: The non-clicker condition resulted in a relatively short drawing duration and better precision index. The COP speed rapidly increased immediately before the release (i.e., APAs), and the rate of increase was lower in the non-clicker condition than in the clicker shooting condition. Furthermore, smaller APAs were significantly correlated with better-aiming precision in the non-clicker condition.CONCLUSION: These findings suggest that using an anticipatory strategy rather than reacting to a clicker can improve archery performance consistency by reducing APA and ensuring a stable shooting posture. This strategy can be used in archery training to predict clicker signals during the aim-release stage.
Aerobic Exercise-Mimetic Effects of Resveratrol on the Prevention of Vascular Endothelial Senescence
Authors: Kim Ji-Seok
Published: June 2023

PURPOSE: Regular exercise has been shown to have anti-aging effects on the vascular system by improving endothelial function and diminishing oxidative stress. However, adherence to an exercise regimen can be difficult for some individuals, particularly those with limited mobility. This study investigated the effects of resveratrol as an exercise mimetic for preventing and improving oxidative stressinduced senescence in vascular endothelial cells.METHODS: Cultured human umbilical vein endothelial cells were used to investigate the reversal effects of laminar shear stress and the protective effects of resveratrol on oxidative stress-induced premature senescence. Senescence was estimated using SA-β-gal staining and western blot analysis, whereas oxidative stress levels were evaluated using MitoSOX staining. Matrigel tube formation and scratch assays were also performed to assess endothelial angiogenic and migration functions.RESULTS: The study showed that laminar shear stress could partly normalize premature endothelial senescence. Resveratrol pretreatment attenuated reactive oxygen species production and prevented senescence in H2O2-induced premature aging. Additionally, resveratrol contributed to maintaining endothelial cells’ angiogenic and migratory functions.CONCLUSIONS: This study demonstrated that laminar shear stress can mitigate the effects of oxidative stress-induced premature senescence. Resveratrol may be a potential substitute for exercise to prevent age-related damage to the endothelium by increasing resistance to oxidative stress and improving endothelial function.
Impact of Cigarette Smoking and Exercise on Arterial Stiffness: A Narrative Literature Review
Authors: Park Wonil , Sung Soon-Chang , Hong Kwang-Seok
Published: June 2023

PURPOSE: Smoking often causes acute and chronic cardiovascular disorders. Cigarette smoking increases oxidative stress, reduces nitric oxide bioavailability, and changes the extracellular matrix, impairing arterial stiffness. However, regular physical activity and smoking cessation significantly and rapidly reverse the detrimental effects. This narrative review summarizes the relevant research that describes the impacts of cigarette smoking on the cardiovascular system and demonstrates the therapeutic or preventative roles of exercise and smoking cessation in smoking-associated arterial stiffness.METHODS: We used scientific search engines, including PubMed, Web of Science, Google Scholar, and Wiley Online Library, to identify previous studies exploring the effects of smoking, exercise, and smoking cessation on arterial stiffness.RESULTS: We discussed the most important therapeutic and/or preventive roles of exercise and smoking cessation in decreasing arterial stiffness. Most studies have demonstrated that acute and chronic smoking increase arterial stiffness. Smoking and physical activity were negatively associated. However, this relationship was often attenuated or reversed during adult exercise interventions. In addition, smoking cessation reversed the effects of smoking on arterial stiffness.CONCLUSIONS: Smoking increases the risk of acute and chronic cardiovascular disease. Cigarette smoking deteriorates arterial stiffness by altering the vascular walls. However, regular exercise and smoking cessation can improve or prevent impaired arterial stiffness.

Authors: Lee Mihyun , Lee Yonghee , Park Saejong
Published: June 2023

PURPOSE: The purpose of this study was to develop an estimation equation that predicts energy expenditure (EE) during swimming exercise based on heart rate (HR). And, we also evaluated the validation for field application and compare it with the existing speedbased swimming EE equation.METHODS: A total of 63 healthy adults (ages 19-49 years) who could swim at various speeds were conveniently sampled. The experiment was conducted in an indoor 25 m pool. The protocol (measurement of individual best performance, 0.4, 0.6, 0.8, <1.0 m/s) was performed for 4 minutes each according to the level of the individual. EE was evaluated using a portable respiratory gas analyzer (K4b2, Cosmed, Italy) and a swimming snorkel (Aqua Trainer Snorkel, Cosmed, Italy). HR was measured using a waterproof HR chest strap (Polar Electro Oy, Polar V800, Finland). A dummy control regression analysis was performed with the EE measured by the respiratory gas analyzer as the dependent variables and sex, age, height, weight, and HR during exercise as independent variables.RESULTS: The participants in this study were randomly divided into two groups; the equation development (n=42) and the validation group (n=21). The estimation of EE during swimming exercise is as follows; EEm=-18.197-1.966 (Gender: men=0, women=1)+.027 (Age, year)+.073 (Height, cm)+.008 (Weight, kg)+.092 (HR, bpm) R2=78% (adj. R2=77.2%). The HR-based swimming EE estimation equation (mean=0.7, difference=6.7) verified by the Bland & Altman plot showed the lowest error, followed by Monpetit (mean=1.6, difference=11.6) and Costill (Mean=0.4, difference=16.7).CONCLUSIONS: The EE during swimming was developed using physical characteristics such as sex, age, height, weight and HR in this study. This swimming EE equation might be used for commercial wearable devices.

In addition, there were significant differences between periods in left tibial torsion angle, non-weight-bearing anklerange of motion, bilateral weight-bearing ankle range of motion, bilateral AN, bilateral posteromedial, right PL, bilateral compositescore, and bilateral Shark skill test.CONCLUSIONS: Tibial rotation exercise is considered valuable as sports injury prevention training due to its effectiveness for lowerextremities functionally and structurally regardless of tibial rotation exercise type.
Blood Flow Restriction Exercise for Successful Aging
Authors: Lee Dohyeon , Ji Minje , Lee Sewon
Published: June 2023

PURPOSE: Generally, an increase in life expectancy is accompanied by various geriatric diseases. However, there is a possibility that geriatric diseases can be prevented and improved through exercise. Exercise is recommended for older adults, but high-intensity exercise (HIE) increases the risk of potential injury. Therefore, blood flow restriction exercise (BFRE) is attracting attention as an alternative for older people who cannot perform HIE. However, mechanisms underlying the physiological effects and benefits of BFRE in older adults have not yet been fully elucidated. This study aimed to summarize the effects of BFRE on aging-related physiological changes and examine its applicability as an effective intervention for successful aging.METHODS: A literature search of electronic databases, including PubMed, Web of Science, and Google Scholar, was conducted for literature published between January 1, 2000, and December 31, 2022.RESULTS: BFRE can effectively increase muscle mass and strength in older adults. Chronic BFRE improved blood pressure, vascular function, and arterial compliance. Although BFRE did not induce changes in bone mineral density (BMD) and cognitive function, positive effects were shown by increasing bone formation markers and neurotrophic factors expression. Relatively, the risk of side effects of BFRE was very low, and even older patients with cardiovascular diseases appeared to have no risk.CONCLUSIONS: This review confirms that BFRE can be an effective and safe intervention to increase muscle mass and strength and improve cardiovascular function. Moreover, BFRE can potentially improve BMD and cognitive function in older adults. In conclusion, BFRE can be an effective intervention for successful aging; additional follow-up studies are needed.

In the 21st century, where urban life and urban population continue to increase, the longing for green and the desire to return to nature attract people to destinations where nature-based activities is carried out. Eco-agro tourism, which is a type of tourism where eco-tourism and agro-tourism intersect, creates positive effects on the socio-cultural, economic and natural environment. Similarly, in the green economy approach, attention is drawn to the positive effects it creates in terms of economic welfare, quality of life and environmental protection. In addition, today the idea of destinations developing an economy based on environmentally friendly production is increasingly important. The study focused on eco-agro tourism, where the natural environment is placed at the center of the economic system in developing rural areas and sustainability in production and consumption can be achieved. It is thought that it is important to reveal the eco-agro tourism potential of the countryside from the perspective of the local people who know the region best. In addition, local people's ideas on eco-agro tourism for a sustainable "green economy" and "green-oriented development" should be known as it will show both the support they will give to tourism development and their participation in tourism activities. From this point of view, Kızıklı Village, which is connected to the Burhaniye district of Balıkesir, was chosen as the research sample. In the study, in which the qualitative research method was adopted, data were collected from 42 participants. The obtained data were subjected to content analysis, thematic groupings were made and their frequencies and percentages were presented to the reader. According to the data obtained from the field; it has been determined that Kızıklı village has eco-agro tourism potential, that the residents of the village will support eco-agro tourism development at a high level, and that eco-agro tourism can be the locomotive in strengthening the existing economic environment and making the green economy applicable in Kızıklı. Among the other results obtained from the research are that eco-agro tourism development and sustainability will be supported by the local people due to their positive contributions to the economic, natural and socio-cultural environment and that the local people will assume responsibilities as stakeholders.

The concept of luxury in the spirit sciences does not have a categorical status, meanwhile, luxury in the history of culture sometimes played a primary role. It is difficult to overstate the role of luxury in the development of art and technology. On the other hand, luxury often served as a cause for the ruin of cities and countries. The article focuses on the role of luxury in ancient ethics. Negative attitudes towards luxury contributed to a positive image of austerity. The positive image of austerity in the Hellenistic schools of antiquity served as the basis for the theoretical synthesis of creed and philosophy in Christianity. The spread of Christianity to the upper strata of Roman society was due to the fact that it was high society that was tired of luxury. Ascesis was subjected not to the poorest strata of society, but to the richest, so the problems of exploitation, it must be admitted, had no direct relation to the genesis of Christianity.

Published: June 2023

Modern society is on the threshold of a fundamental ontological transformation, in which a significant role is assigned to intelligent management systems that can change the face of society and determine the vector of its further development. The capabilities of intelligent management systems and the potential risks associated with its functioning quite reasonably acquire the status of an object of socio-philosophical analysis, the results of which should help to find an answer to the question of the fundamental possibility of transferring the entire volume of managerial manipulations to the competence of artificial management systems. The potential of possible transformations actualizes the need to discuss socially significant phenomena, such as: potential growth of unemployment, issues of ethics, moral choice and legal responsibility.

The problem of the abolition of privacy is quite common in modern discourse. Technology is ever-present in our daily lives, and, of course, they have a diverse impact on it. Despite the need for privacy, people often ignore all possible measures to ensure it, exposing their personal data to the public and ignoring information in user agreements, signing or accepting them without looking, without thinking about the possible consequences associated with a partial loss of privacy.
The antagonistic dimension of the political: from Carl Schmitt to Chantal Mouffe
Authors: Balakleets Natalia A. , Bakshutova Ekaterina V. , Mukhametshina Natalia S.
Published: June 2023

The article presents the results of the theoretical analysis of the phenomenon of the political, understood in its antagonistic dimension, in the context of classical and modern political and philosophical doctrines. The philosophical meanings and political implications of the antagonistic concepts of the political by Carl Schmitt and Chantal Mouffe, as well as the alternative concept of Ulrich Beck, are revealed. The authors interpretation of Schmitts friend-enemy distinction is proposed as an inclusive antagonism that retains its political significance in the presence of an open possibility of its constitution. On the basis of the analysis of U. Becks ideas outlined in his work The Invention of the Political, the theoretical inconsistency of the conflict-free model of the political is substantiated. The comparative analysis of the phenomenon of the political in the concepts of C. Schmitt and Ch. Mouffe has been carried out. The contingent nature of friend-enemy distinction, presented in the concept of Ch. Mouffe, in which antagonism becomes a modus of agonism, is substantiated.
Arnold Toynbee as a philosopher and the theologist: (post)metaphysical meanings of history
Authors: Faritov Vyacheslav T. , Borisova Tatyana V.
Published: June 2023

The article is devoted to the explication of post-metaphysical tendencies in the philosophy of history based on the concept of A. Toynbee. A comparative analysis of the historiosophical ideas of Toynbee with the teachings of O. Spengler, N.O. Lossky, A. Augustine and F. Nietzsche. The thesis is substantiated that the key points in determining the meaning of the historical process in Toynbees theory are the ideas of deification and the superman. It is concluded that Toynbees historiosophical concept is an attempt to respond to the situation of total devaluation of meaning-forming paradigms during the crisis of Western civilization.

The essence of fractal geometry is disclosed, the subject of study of which is the point as the self-similarity of Genesis. The essence of the torsion form of movement was analyzed. A new concept of space and time has been developed. The ideological and theoretical proximity of the provisions of modern science and ancient Eastern philosophy has been determined. G. Kantors axiom on continuity (1872), as well as K. Gdels incompleteness theorem, has been interpreted. The possibility of science entering the sphere of the nomen world has been proven. The theory of pulsating Chaos or Supersymmetry is based. It has been revealed that events occur not only in space and time, but that space and time themselves affect events.

Digestibility is the most important nutritional functionality of starchy foods. Unfortunately, in Indonesia, this functionality has not been extensively studied due to the relatively challenging methods involving enzymes. This research aims to determine the optimal pH and enzyme ratio of α-amylase (AA) and glucoamylase (GA) for starch hydrolysis tests and apply them to characterize steamed, baked, and fried wheat doughs. For optimization, hydrolysis was carried out at 37 °C with an enzyme-to-substrate ratio (E/S) of 100 mL/g for 120 min. Samples of wheat dough obtained from three major dough producers in Banyumanik, Semarang, Indonesia was then tested for starch hydrolysis, texture, chemical analyses, sensory, and hedonic test. The collected data were analysed using principal component analysis (PCA). Under the determined conditions, the optimal pH and AA/GA ratio were found to be 6.6 and 0.5. Regarding quality of processed doughs, the steamed dough exhibited a cohesive texture, a soft sensory profile with a pleasant aroma, sweet taste, and was most preferred by the panellists. The baked dough was hard in texture, high in ash content, and brown in colour. The fried dough poses high starch hydrolysis, chewy texture, adhesion, solid particles, protein content, and relatively high lipid. The sensory evaluation indicated that the fried dough poses an oily, rancid, foreign aroma, and bitter and salty taste. It can be concluded that at a temperature of 37 °C, an enzyme-to-substrate ratio of 100 mL/g, and a reaction time of 120 min, the optimal starch hydrolysis of processed wheat dough can be achieved at a pH of 6.6 and an AA/GA ratio of 0.5. Furthermore, steaming resulted in a unique property of dough compared to the baked and fried, while the latter two yielded products with similar properties.

Çalışanların iş ve aile yaşamları arasında sağlıklı bir denge kurarak bir yandan iş yaşamlarında verimli ve üretken olmaları, öte yandan özel yaşamlarında ailelerine daha fazla zaman ayırarak mutlu olmaları mümkündür. Fakat, iş ve aile yaşam alanlarının sürekli değişken yapıda olması bu dengenin kurulmasını zorlaştırmaktadır. İş-aile yaşam çatışması çalışanların kişisel mutlulukları ve yaşam tatminlerinin yanı sıra çalıştıkları işletmeler açısından önem taşıyacak şekilde iş stresi, iş doyumu ve örgütsel bağlılık düzeylerini de etkileyebilmektedir. İşaile yaşam çatışmasının etkin bir şekilde yönetilmesi için uygun insan kaynakları politikalarının üretilmesi, örgütsel düzenlemelerin ve uygulamaların gerçekleştirilmesi önemlidir. Bunun için ise, farklı kurumsal ortamlarda ve pazarlarda faaliyet gösteren işletmelerde çalışanların iş-aile yaşam çatışması düzeylerinin işleriyle ilgili tutum ve davranışlarını ne yönde ve ne derecede etkilediğinin belirlenmesi gerekir. Çalışanlar iş-yaşam dengelerini kurmaya çalışırken birtakım bireysel ve çevresel faktörlerin etkisi altına girmektedirler. Buradan hareketle, çalışmanın amacı yoğun çalışma saatleri yaşanan bankacılık sektörü kadın çalışanları için iş-yaşam dengesini etkileyen faktörlerin sıralı lojistik regresyon yöntemiyle analizidir. Analiz sonucunda; medeni durum, çocuk sayısı, evde yardımcının varlığı, çalışılan pozisyon, eş desteği, aile desteği ve yönetici desteğinin istatistik anlamlı etkili faktörler olduğu belirlenmiştir.
Secondary structure in polymorphic forms of alpha-synuclein amyloids

Numerous Alpha-synuclein amyloid structures available in PDB enable their comparative analysis. They are all characterized by a flat structure of each individual chain with an extensive network of inter-chain hydrogen bonds. The identification of such amyloid fibril structures requires determining the special conditions imposed on the torsion angles. Such conditions have already been formulated by the Authors resulting in the model of idealised amyloid. Here, we investigate the fit of this model in the group of A-Syn amyloid fibrils. We identify and describe the characteristic supersecondary structures in amyloids. Generally, the amyloid transformation is suggested to be the 3D to 2D transformation engaging mostly the loops linking Beta-structural fragments. The loop structure introducing the 3D organisation of Beta-sheet change to flat form (2D) introduces the mutual reorientation of Beta-strands enabling the large-scale H-bonds generation with the water molecules. Based on the model of idealised amyloid we postulate the hypothesis for amyloid fibril formation based on the shaking, an experimental procedure producing the amyloids.

Background and Objectives: Community-acquired pneumonia (CAP) is one of the most common life-threatening infec- tions, occurring in the community or within the first 48 hours of a patient's hospitalization. The present study aimed to investigate the frequency of pathogenic bacteria and their antibiotic resistance pattern in the sputum of patients with commu- nity-acquired pneumonia in Yasuj from 2018 to 2019.
Materials and Methods: In the present study, 128 patients with CAP were included. Under aseptic conditions clinical samples including sputum collected from each patient were sent to the Microbiology Laboratory. Specific culture media and biochemical tests were used to identify the bacteria. Antimicrobial resistance patterns of the isolates were examined by disc diffusion. DNA was extracted from sputum using the phenol-chloroform method. The PCR method was used for the molec- ular detection of bacteria. Data were analyzed using SPSS software version 22 and the chi-square test.
Results: The most common clinical symptoms in patients were sputum (68.8%), fever (64.1%), shortness of breath (60.2%), cough (50.8%), and chest pain (24.2%). A total of 133 bacteria were identified by culture and 117 bacteria by PCR. In the current study, the most prevalent organisms were Streptococcus pneumoniae (24.1%), Hemophilus influenzae (18%), Staph- ylococcus aureus (13.5%), and Moraxella catarrhalis (11.4%). Antibiogram test showed that most of the Gram-negative bacteria were resistant to levofloxacin (22.6%), rifampin (20.8%) and ceftriaxone (17%), and the highest resistance rate to clindamycin (43.1%), ciprofloxacin (43.1%) and amoxicillin (41.4%) were detected in the Gram-positive bacteria. Cefepime was the most effective antibiotic against Gram negative bacteria.
Conclusion: S. pneumoniae was the most prevalent bacteria identified by culture and PCR methods in patients with CAP, indicating an important role of this bacterium in the pathogenesis of CAP. According to the results, cefepime can be used to treat patients with CAP with Gram-negative bacteria. In the present study, S. pneumoniae, S. aureus, P. aeruginosa, H. influenzae, M. catarrhalis, and K. pneumoniae have been isolated from the CAP patient population with varying frequencies. This is consistent with various studies in different parts of the world.
