    Combating with COPD by QiGong Physical and Mental Exercise

    Kaplan Serin, Emine

    Physical activity levels of patients with chronic obstructive pulmonary disease (COPD) are low due to the symptoms of COPD. The patients diagnosed with COPD are headed for complementary and alternative treatments to reduce the COPD symptoms, facilitate the treatment, and increase their physical activity. One of these treatments is QiGong, which is not yet common in our country. QiGong is a type of exercise based on ancient Chinese medicine, and mainly consists of active and passive exercises. These exercises open energy channels in the body, and thus prevent and/or heal diseases by establishing energy balance in the body through meditation, breath control, and bodily exercises. According to a literature review abroad, there are a small number of scientific studies related the therapeutic effect of QiGong exercises on symptom control, anxiety, reduction of stress and depression, increase in physical activity and quality of life, and the development of lung function of patients with COPD. By considering the educative role of nurses, it is important that the nurse has adequate knowledge of the treatment and care of patients with COPD. Therefore, this review is compiled to be informative about the effects of QiGong in the treatment of COPD, and assistance to subsequent studies.

    On the Construction of a Semiparametric Family of Bivariate Copulas Using the Opposite Diagonal Section of Copulas

    Susam, Selim Orhun; Chesneau, Christophe

    In this article, a new semiparametric family of bivariate copulas is proposed and studied. The copulas of this family innovate in their construction; they are based on an original univariate generating function involving the opposite diagonal section of intermediary copulas. Several of their crucial properties are examined. In the practical part, we use them to estimate the reliability parameter in a stress-strength-dependent setting, including an estimation approach based on the Bernstein copula. Finally, their applicability and good performance are confirmed using a data set related to the logarithmic concentrations of two chemical elements in water samples.

    Determination of oxidative stress responses caused by aluminum oxide (γ-Al2O3 and α-Al2O3) nanoparticles in Gammarus pulex

    Serdar, Osman; Aydin, Ayşe Nur; Çimen, Isıl Canan Çiçek

    The rapid growth in the use of aluminum oxide nanoparticles (Al2O3 NPs) in various fields such as medicine, pharmacy, cosmetics industries and engineering, and the fact that these NPs and their wastes mix with the aquatic environment and damage the aquatic ecosystem, affect the organisms in the water, enter the food chain and reach humans is a major problem is cause for concern. The aim of this study is to investigate the oxidative stress caused by two separate forms of aluminum oxide, γ-Al2O3 and α-Al2O3, in Gammarus pulex, which is a good indicator species, with biochemical parameters. For this purpose, G. pulex was exposed to different concentrations (0, 10, 20, 40 ppm) of γ-Al2O3 and α-Al2O3 separately. The experiments were carried out for 24 and 96 h by creating 3 repeated experimental groups consisting of 4 groups. For biomarker analysis, superoxide dismutase (SOD), catalase (CAT) activities and glutathione (GSH) and thiobarbituric acid (TBARS) levels were performed using an ELISA kit. As a result of the in experimental study, it was observed that both nanoparticles affected oxidative stress and antioxidant parameters after 96 h compared to the control group. Increases in SOD activity were observed, γ-Al2O3 caused a decrease in CAT activity at 24 h, and α- Al2O3 caused increases in CAT activity at 96 h. Decreases in GSH levels and increases in TBARS levels have been observed.

    Muchlisin, Zainal Abidin; Aldila, Dhea Febby; Sarah, Putri Inten; Eriani, Kartini; Hasri, Iwan; Fadli, Nur; Muhammadar, Abdullah Abbas; Handayani, Luvi Syafrida; Maulida, Siti; Siti-Azizah, Mohd Nor

    There is no known artificial breeding method for depik fish Rasbora tawarensis. Sperm extender and the dilution ratio are crucial factors in the artificial breeding of fish. The current study aimed to assess the effect of several common fish sperm extenders and its dilution ratio on sperm characteristics and fertilization of depik fish eggs. Two series of experiments were performed to find the best extender and its dilution ratio. In the first experiment, five types of extenders were tested: Ringer's solution, physiological solution, coconut water, sugarcane water, and roomie water. The second experiment studied four dilution levels of sperm and extender (v/v): 1:20, 1:30, 1:40, and 1:50. Every treatment was conducted in four replicates and the experiments were conducted consequently so that the findings in the first experiment were applied in the second. The first experiment showed that Ringer's is the best extender for depik sperm with sperm motility, fertilization and hatching rates of 71.00%, 69.30%, and 53.66%, respectively; and the second experiment revealed that Ringer's at dilution ratio 1:40 gave higher sperm motility, fertilization, and hatching rates of 74.66, 70.33, and 59.00%, respectively. In conclusion, Ringer's solution was the most favorable extender for sperm which yielded best fertilization results at 1:40 dilution ratio (sperm:extender, v/v) in depik fish.

    Evaluation of antioxidant, antimicrobial, and bioactive properties and peptide sequence composition of Malatya apricot kernels

    Aydın, Çağlar Mert; Çelikbıçak, Ömür; Hayaloğlu, Ali Adnan

    BACKGROUND: This study used four different apricot (Prunus armeniaca) kernels cultivated in Malatya during two consecutive years. The varieties were Hacihaliloglu, Hasanbey, Kabaasi, and Zerdali. The physicochemical properties of the kernels were determined, and the bioactive content of the kernels was evaluated using kernel hydrolysates prepared using trypsin. RESULTS: With regard to the physicochemical properties of the kernels, the dry matter ratio and protein content were the highest in the Hacihaliloglu variety; the ash ratio was the highest in the Kabaasi variety, and the free oil ratio was the highest in the Hasanbey variety. The bioactive compound content changed according to kernel variety. Angiotensin-converting enzyme inhibitors activity was found to be the highest in the Hacihaliloglu and Hasanbey varieties, which had the lowest amygdalin content, and Zerdali had the highest amygdalin content. The antioxidant and antimicrobial effects of the kernels varied, with Hasanbey and Kabaasi generally having the highest content in both analyses. Moreover, a concentration of 20 mg mL−1 of the hydrolysate was determined to have a destructive effect for the microorganisms used in this study. The storage protein of the kernels, except Hacihaliloglu, was found to be Prunin 1, with the longest matching protein chain in the kernels being R.QQQGGQLMANGLEETFCSLRLK.E. CONCLUSION: The results suggest that the peptide sequences identified in the kernels could have antihypertensive, antioxidative, and Dipeptidyl peptidase IV (DPP-IV) inhibitory effects. Consequently, apricot kernels show potential for use in the production of functional food products. Of the kernels evaluated in this study, Hacihaliloglu and Hasanbey were deemed the most suitable varieties due to their higher bioactive content and lower amygdalin content.

    Fastener and rail surface defects detection with deep learning techniques

    Yilmazer, Merve; Karakose, Mehmet

    The railways, which are frequently used by countries for both passenger and freight transportation, should be checked periodically. Controls made with classical methods are slow and there are often overlooked faults. This work suggests a novel deep learning-based technique for identifying fastener and railway track surface defects. Within the scope of the proposed method, firstly, the railroad track was observed using an autonomous drone. Shaky images in the recorded video were removed with a video stabilization algorithm. Frames were created and labeled from the video, and rail and fastener regions were detected using the Faster R-CNN deep neural network. Fault detection was performed through ResNet101v2-based classification using different datasets for identifying surface detects in rails and different datasets for the detection of fasteners. The proposed method was experimentally shown to have a 98% accuracy rate for detecting rail surface flaws and a 95% accuracy rate for detecting fastener flaws. A user interface was developed to display the identified faulty images on computers, tablets, and mobile phones via a mobile application. The system, which was previously proposed in a different study, was retrained by going through the video stabilization step, thus improving the fault detection rate, and the method was also included in the user interface module. This study contributes to the processing of ever-increasing video data with deep learning-based methods. It is also anticipated that it will benefit researchers working in the field of railway non-contact fault detection.

    Predicting and optimizing maximum flexural strength of planar composite plate shear walls – concrete filled with the application of LR and RSM

    Polat, Erkan; Polat, Elifcan Göçmen

    Traditional theoretical models, while conservative, overlook the complex, nonlinear interactions between material and geometric parameters that influence wall flexural strength. Additionally, the extent to which these models maintain their conservative assumptions across varying parameters remains uncertain. This study aims to develop advanced predictive models for the flexural strength of planar composite plate shear walls—concrete filled (C-PSW/CF) by employing Linear Regression (LR) and Response Surface Methodology (RSM). Central Composite Design (CCD) was utilized to design numerical experiments to analyze the effects of varying parameters, including steel plate yield strength, concrete compressive strength, wall depth, depth-to-thickness ratio, and reinforcement ratio. A validated complex finite element modeling (FEM) procedure was used to analyze numerical experiments involving varying parameters of the selected variables. Both LR and RSM were applied to the generated dataset to formulate predictive equations for the maximum moment capacity of walls. Interaction plots were developed to reveal the nonlinear relationships between the variables and identify the most effective parameters influencing the wall strength. Comparisons between theoretical predictions, RSM, and LR models revealed that RSM provided the most accurate predictions, closely aligning with FEM results and effectively capturing the nonlinear interactions between wall parameters. The findings of this paper contribute to the development of more practical, accurate and optimized design methods for C-PSW/CF, ultimately improving both structural safety and efficiency.

    The Relationship Between Compassion Fatigue and Professional Self-Concept in Psychiatric Nurses

    Durmaz, Hatice; Karakaş, Sibel Asi; Erçel, Şeyda

    The current study examined the relationship between compassion fatigue and professional self-concept in psychiatric nurses. Participants included 156 nurses working in a mental health and disorders hospital in Turkey. Data were collected via a sociodemographics form, the Compassion Fatigue subscale of the Professional Quality of Life Scale, and Professional Self-Concept Scale. Participants exhibited low levels of compassion fatigue and high levels of professional self-concept. A significant negative relationship was found between participants’ mean compassion fatigue scores and mean professional satisfaction, professional competence, and professional self-concept scores (p < 0.05). Professional satisfaction, professional competence, and professional self-concept decreased with increasing compassion fatigue. Nurses should be provided emotional support through in-service training and effective communication to prevent burnout.

    Maxillary sinus detection on cone beam computed tomography images using ResNet and Swin Transformer-based UNet

    Çelebi, Adalet; Imak, Andaç; Üzen, Hüseyin; Budak, Ümit; Türkoğlu, Muammer; Hanbay, Davut; Şengür, Abdulkadir

    Objectives: This study, which uses artificial intelligence-based methods, aimed to determine the limits of pathologic conditions and infections related to the maxillary sinus in cone beam computed tomography (CBCT) images to facilitate the work of dentists. Methods: A new UNet architecture based on a state-of-the-art Swin transformer called Res-Swin-UNet was developed to detect the sinus. The encoder part of the proposed network model consists of a pre-trained ResNet architecture, and the decoder part consists of Swin transformer blocks. Swin transformers achieve powerful global context properties with self-attention mechanisms. Because the output of the Swin transformer generates sectorized features, the patch expanding layer was used in this section instead of the traditional upsampling layer. In the last layer of the decoder, sinus diagnosis was conducted through classical convolution and sigmoid function. In experimental works, we used a data set including 298 CBCT images. Results: The Res-Swin-UNet model achieved more success, with a 91.72% F1-score, 99% accuracy, and 84.71% IoU, outperforming the state-of-the-art models. Conclusions: The deep learning-based model proposed in the present study can assist dentists in automatically detecting the boundaries of pathologic conditions and infections within the maxillary sinus based on CBCT images.

    An evaluation of societal perception of monkeypox in terms of disease anxiety and stress levels: A Turkish sample

    Yeşiltepe, Akgün; Ayşe, Ç.A.L.

    Objective: The purpose of this research was to examine community perception of monkeypox in terms of epidemic anxiety and stress levels. Methods: This research was performed as a descriptive, cross-sectional study. The research was conducted with 1001 individuals between September and December 2022. AMOS 24, JAMOVI, and SPSS version 25 software were employed. The data were collected using a descriptive form, the Epidemic Anxiety Scale, and the Perceived Stress Scale. Results: The mean Epidemic Anxiety Scale score was 52.47 ± 14.52, and the mean Perceived Stress Scale score was 41.88 ± 6.83. Significant positive correlation was determined between the Epidemic Anxiety Scale and the Perceived Stress Scale (r = 0.350, p =.000). A one-unit increase in perceived stress caused a 0.360 increase in epidemic anxiety (ß = 0.360). In addition, having heard of and fearing monkeypox, thinking about its ability to cause an epidemic, and perceived stress emerged as significant predictors of epidemic anxiety. Conclusion: The community was found to exhibit a moderate level of epidemic anxiety and a low level of perceived stress. Epidemic anxiety levels increased in line with perceived stress levels. We recommend that individuals in need receive support by determining epidemic anxiety and perceived stress levels in the community.

    Aydin, Handan; Torgut, Gülben

    In this study, firstly, the copolymer of acrylonitrile (AN) and styrene (St) was synthesized by solution polymerization method using 2,2′-azobisisobutyronitrile (AIBN) as an initiator. The composites of copolymer incorporating lanthanum (III) chloride (3, 6, 9 and 18 wt%), the rare earth element (REE), were prepared and thin films were produced by thermal evaporation method for optical measurement. The samples were characterized by attenuated total reflectance Fourier transform infrared (ATR–FTIR), scanning electron microscopy–energy dispersive spectroscopy (SEM–EDS) and X-ray diffraction (XRD). The glass transition temperature, which is one of the thermal properties of the synthesized copolymers and composites, was examined with a differential thermal analyzer. The changes in the optical properties of the samples produced with LaCl3 dopant were investigated using the UV–VIS spectroscopy. The optical band gaps of the samples were calculated using Tauc equation. As a result of the optical studies, it was observed that there was a change in the conductivity properties of the samples with the addition of LaCl3. The present results showed the advantage of using LaCl3 as a filler to improve the optical properties of poly(AN-co-St) samples.

    World of Crayfish™: a web platform towards real-time global mapping of freshwater crayfish and their pathogens

    Ion, Mihaela C.; Bloomer, Caitlin C.; Bărăscu, Tudor I.; Oficialdegui, Francisco J.; Shoobs, Nathaniel F.; Williams, Bronwyn W.; Scheers, Kevin; Clavero, Miguel; Grandjean, Frédéric; Collas, Marc

    Freshwater crayfish are amongst the largest macroinvertebrates and play a keystone role in the ecosystems they occupy. Understanding the global distribution of these animals is often hindered due to a paucity of distributional data. Additionally, nonnative crayfish introductions are becoming more frequent, which can cause severe environmental and economic impacts. Management decisions related to crayfish and their habitats require accurate, up-to-date distribution data and mapping tools. Such data are currently patchily distributed with limited accessibility and are rarely up-to-date. To address these challenges, we developed a versatile e-portal to host distributional data of freshwater crayfish and their pathogens (using Aphanomyces astaci, the causative agent of the crayfish plague, as the most prominent example). Populated with expert data and operating in near real-time, World of Crayfish™ is a living, publicly available database providing worldwide distributional data sourced by experts in the field. The database offers open access to the data through specialized standard geospatial services (Web Map Service, Web Feature Service) enabling users to view, embed, and download customizable outputs for various applications. The platform is designed to support technical enhancements in the future, with the potential to eventually incorporate various additional features. This tool serves as a step forward towards a modern era of conservation planning and management of freshwater biodiversity. Copyright 2024 Ion et al.

    The effects of Cinnamomum zeylanicum extract (CZE) at different rations (0%, 1%, 3% and 5%) on gelatin (GL)–polyvinyl alcohol (PVA) blend films were evaluated in relation to the structural, tensile strength, physical, antimicrobial and antioxidant properties of the films in this study. The results showed that water barriers of the film samples decreased, but the UV-blocking property increased and became opaque at the highest GLPVA5 film. The tensile strengths of GLPVA, GLPVA1, GLPVA3 and GLPVA5 films were 1.21, 1.78, 1.62 and 1.95 MPa, respectively. The antimicrobial effect of these films was determined against Escherichia coli, Enterococcus faecalis, Salmonella typhimurium and Bacillus cereus according to the parallel stick method. Antioxidant properties of cinnamon extract were investigated using 2,2-diphenyl-1-picryl-hydrazil (DPPH) methods. The % inhibition of DPPH was found to be 82.00. No antibacterial effect was detected for B.cereus and E. faecalis at 0%, 1%, 3% and 5%. While no activity was observed in 0%, 1% and 3% cinnamon, 7.5 and 3.0 mm zones were detected in S. typhimirium and E. coli, respectively, in 5% cinnamon. The results suggest that the film samples could be used in a potential packaging with antioxidant and antibacterial properties.

    Development and in-depth experimental characterization of novel TiZrNbHfTaOx reinforced 316L stainless steel for advanced nuclear applications

    Güler, Ömer; Albayrak, M. Gökhan; Başgöz, Öyküm; Kavaz, E.; Alkarrani, Hessa; ALMisned, Ghada; Tekin, H.O.

    Oxide Dispersion Strengthened (ODS) materials are known for their exceptional performance in high-temperature and radiation environments. This study explores the radiation shielding properties of 316L Stainless Steel reinforced with TiZrNbHfTaOx High-Entropy Oxide (HEO). By integrating HEOs into the 316L stainless steel matrix, we aim to enhance its structural and radiation shielding properties. The HEO was synthesized using high-energy ball milling and oxidation processes, followed by thorough characterization using X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS). Our results indicate significant improvements in both gamma-ray and neutron shielding properties. The 316L SS samples reinforced with 20 % HEO exhibited the highest mass attenuation coefficients (MAC), lowest half-value layers (HVL), and highest effective atomic numbers (Zeff) across all tested photon energies. These enhancements are attributed to the high atomic number elements and unique synergistic effects of HEOs. Neutron shielding was evaluated through equivalent dose rate measurements, with the 20 % HEO sample demonstrating the highest absorbed dose rate percentage and superior neutron interaction cross-sections. Benchmarking against standard materials confirmed the superior performance of HEO-reinforced 316L SS, making it a promising candidate for advanced radiation shielding in nuclear reactors and other high-radiation environments. Our findings suggest that HEO reinforcement not only improves mechanical properties but also significantly enhances the radiation protection capabilities of 316L stainless steel.
