Acute Changes in Electrophysiological Brain Dynamics in Elite Karate Players
(Springer international Publishing Ag, 2020) Balcıoğlu, Taylan Hayri; Balcioglu, Taylan Hayri; Ozcan Cakir, Canan Elif; Goksel Duru, Dilek; Antrenörlük Eğitimi Bölümü
Regular physical exercise has enhanced effects on the human anatomy and functionality. Recently, an effect of a single set of exercise is shown to have positive effects on mood and on cognitive functioning. The aim of this study is to investigate the effect of a single bout of moderate exercise on the brain electrophysiological dynamics in resting-state condition and under the mental workload situation from elite-level athletes. For this purpose, electroencephalogram (EEG) is measured before and after the exercise sessions from 17 elite karate players who are members of the national karate team of Turkey. Blood lactate measurements are implemented to monitor the volunteers before EEG measurements. EEG data are analyzed using three metrics: conventional band power of each electrode, coherence metrics between electrodes for each band and source coherence values corresponding to each frequency band. Each metric is statistically analyzed between pre- and post-values, and results revealed that in all frequency bands, right parietal electrode had increased connection values which are thought to be related to ongoing sympathetic nervous system response observed during the recovery period. Another finding is the enhanced connectivity of frontal sources under the resting state as well as during the increased mental workload periods.

Adsorption Mechanisms, Kinetics and Photoactivities of Green Synthesized Hydroxyapatite Supported Zno and La-Zno Catalysts
(Pergamon-elsevier Science Ltd, 2024) Tuncel Turan, Duygu; Okte, A. Neren; Temel Eczacılık Bilimleri Bölümü
In this study, hydroxyapatite (HAP) is synthesized by a co-precipitation method from the waste eggshell, utilized as a support for ZnO (ZnO-HAP) and La-ZnO (La-ZnO-HAP) and employed to degrade methyl orange (MO) and methylene blue (MB) dyes under UV irradiation. Water vapor adsorption as relative humidity (84 % RH) on the HAP structure and the as-prepared catalysts are also examined. The characteristic ZnO and HAP reflections are detected in X-ray diffraction (XRD) analysis of ZnO-HAP, La-ZnO-HAP and humidified samples. ZnO and La-ZnO existence is also verified by scanning electron microscopy-energy dispersive X-ray (SEM-EDX) analysis, UV-Vis diffuse reflectance (UV-Vis DRS) spectra and X-ray photoelectron spectra (XPS). ZnO and La-ZnO loading on the HAP induce the formation of mesoporous structures with high surface areas. Dark adsorption capacities and photoactivities of the as-prepared samples are explored regarding electrostatic interactions, Lewis acid-base interactions and hydrogen bonding for both MO and MB. In particular, La-ZnO-HAP 500 degrees C and La-ZnO-HAP 500 degrees C (RH) exhibit improved adsorption abilities and photoactivities. The pseudo-second order model describes the kinetic behavior of all samples under dark conditions. Unhumidified samples follow Langmuir isotherm while Freundlich isotherm better fits humidified ones. Under irradiation, the Langmuir-Hinshelwood kinetic model describes the photoactivities of all samples. The four recycling tests confirm the stabilities of HAP 100 degrees C, HAP 500 degrees C, ZnO-HAP 500 degrees C and La-ZnO-HAP 500 degrees C. This study suggests that the ZnO or La-ZnO loaded HAP catalysts prepared in the presence and absence of humid conditions are considered promising materials for environmental remediation.

(Taylor & Francis Ltd, 2024) Şener, Göksel; Koroglu, M. Kutay; Hersek, Irem; Ertas, Busra; Sen, Ali; Sener, Goksel; Ercan, Feriha; Eczacılık Meslek Bilimleri Bölümü
The possible protective effects of Myrtus communis L. (MC) extract on a high fat diet (HFD)-induced testicular injury in a rat model were investigated using histological and biochemical methods. Wistar albino rats were divided into three groups: a standard diet control group; a HFD group; and an HFD+MC group. The HFD and HFD+MC groups were fed with a HFD for 16 weeks. MC extract (100 mg/kg) was given orally five days a week to the rats in the HFD+MC group during the last four weeks of the experiment. Leptin, triglyceride, high-density lipoproteins, cholesterol, estrogen, testosterone, LH and FSH were analyzed in blood serum. Sperm parameters were evaluated from the epididymis. Testicular morphology, proliferative, apoptotic and NADPH oxidase-2 (NOX2)-positive cells were evaluated histologically. Testicular oxidative stress parameters were analyzed biochemically. In the HFD group, lipid and hormone profiles were changed, abnormal spermatozoa, degenerated seminiferous tubules with apoptotic and NOX2-positive cells were increased in number, and sperm motility and germinal proliferative cells decreased compared to the control group. Moreover, testicular malondialdehyde, 8-hydroxy-2-deoxyguanosine and myeloperoxidase levels increased, whereas glutathione and superoxide dismutase levels decreased in the HFD group compared to the control group. All these histological and biochemical features were ameliorated by MC treatment of HFD-fed rats. In conclusion, HFD caused alterations in sperm parameters and testicular morphology by increasing oxidative damage and apoptosis. MC extract may have potential protective effects by inhibiting oxidative damage.

Analysis of Selected Steroid Hormones in Sea of Marmara Sediment Samples by Lc-esi/Ms-ms
(Istanbul Univ, Fac Pharmacy, 2023) Yurdun, Türkan; Yurdun, Turkan; Eczacılık Meslek Bilimleri Bölümü
Background and Aims: Sediment is the general name given to the muddy structure located at the bottom of aquatic environments such as the sea. In our study, the amounts of steroid hormones were investigated in the sediment samples taken from the Marmara Sea. According to other studies, it has been determined that the excess of the hormone load in the sediments may be an indicator of human/animal sourced pollution, as well as the negative effects of the hormones mixed in the seas with the ecological cycle on the health of humans and animals.Methods: In our study, 31 selected human/animal, plant, natural and synthetic hormone-steroids were studied using Liquid Chromatography Electrospray Ionization Tandem Mass Spectrometry (LC-ESI/MS-MS). Methanol and QuEChERS were used as extraction methods. Sediment samples were taken from a total of 27 points selected for sampling at the Marmara Sea.Results: According to the results we found, the androgens: androsterone (24.50-1718.18 ng g-1), testosterone (86.30-1600.32 ng g-1); the estrogens: mestranol (33.73-228.32 ng g-1), equilin (53.44-1232.53 ng g-1); the progestagens; pregnenolone (37.50374.76 ng g-1), progesterone (39.96-405.60 ng g-1); levonorgestrel (325.25 and 937.93 ng g-1); the fecal sterols: cholestanone (57.57-1726.32 ng g-1), coprostanol + epicoprostanol (51.43-1370.33 ng g-1); and the plant sterol; campesterol (35.30-1859.90 ng g-1) were the compounds detected.Conclusion: Estrogens and progestogens are active components of birth control pills, and cholestanone and coprostanol + epicoprostanol are steroids that are indicative of human/animal pollution. Coprostanol + epicoprostanol and cholestanone, which are indicators of fecal pollution, were detected in all sediment samples. In our study, steroid hormones were detected for the first time in Sea of Marmara sediments and possible environmental risks were evaluated.

(Sagamore Publishing Llc, 2023) Pınar, Salih; Ozer, Dilara; Pinar, Salih; Antrenörlük Eğitimi Bölümü
The aim of this study is to examine the motor skill levels of children aged 3-6 years with Autism spectrum dis-order (ASD) in comparison with their typically devel-oping (TD) peers and to reveal their needs for motor support programs. The research group consisted of 88 participants aged 3-6 years, including 43 children (40 boys and 3 girls) diagnosed with ASD attending spe-cial education and rehabilitation institutions, and 45 TD children (23 boys and 22 girls) receiving pre-school education in a private institution (ASD=57.4 months, +/- 9.32 - TD=59.06 months, +/- 8.61). The Peabody Devel-opmental Motor Scale-2 (PDMS-2) and the Turkish Ver-sion of the Gilliam Autism Rating Scale-2 (GARS-2-TV) were used as data-collection tools in the study. The Mann-Whitney U test was used for the two-group com-parisons of the parameters that did not exhibit normal distribution in the analysis of the data. The Spearman correlation analysis was applied to determine the relationship between the variables. The significance was evaluated at the p<0.05 level. As a result of the research, the balance, locomotor and manipula-tive skills and total gross motor scores of the children with ASD were found to be lower than those of the TD children (p<0.05). In addition, it was observed that there was a significant correlation between GARS-2 -TV scores and PDMS-2 scores of the children with ASD (p<0.05).

Analyzing Critical Success Factors of Sustainable Knowledge Management: an Interval-Valued Neutrosophic Approach
(Mdpi, 2024) Çaloğlu Büyükselçuk, Elif; Bulak, Muhammet Enis; Buyukselcuk, Elif Caloglu; Endüstri Mühendisliği Bölümü
Knowledge management (KM) is a structured approach that includes the organized procedures of generating, capturing, arranging, storing, retrieving, distributing, and harnessing an organization's knowledge resources to attain its goals and improve its effectiveness. Encountering uncertainty and managing imprecise information are fundamental aspects of KM that cannot be avoided. In this context, sustainable KM aims to solve these issues and address prioritizing the long-term sustainability and efficiency of knowledge-related processes within an organization. The aim of this study is to structure a sustainable KM concept for organizations and identify the most common critical success factors (CSFs) with a novel analytical approach. In this context, the Interval-Valued Neutrosophic methodology, which is one of the multi-criteria decision methods (MCDMs), was adopted to evaluate and weight the determined CSFs. Four main headings-KM, environmental, economical, and social criteria-are evaluated along with their subfactors. Our findings show that KM is found to be the most important, and environmental factors followed KM. When the results are examined in terms of subfactors, cleaner production is found to be the most significant, with a global weight value of 11.13.

(Elsevier Science inc, 2023) Öztürk, Gizem; Kolcu, Merve; Hemşirelik Bölümü
Purpose: This study was conducted to determine the relationship between child and parents' health behaviors and childhood obesity. In addition, an adaptation of the Turkish version of the Family Health Behavior Scale (FHBS) was performed in this study.Design and methods: This is a descriptive and methodological study. The research sample consisted of 358 parents who have a child between the ages of 5 and 12 studying in one of the seven state schools at the kindergarten, primary, and secondary school levels in Istanbul. Data were collected between February 2022 to May 2022 using the Parent and Child Descriptive Information Form, the Family Nutrition and Physical Activity (FNPA) Screening Tool, and the FHBS. IBM SPSS 25.0 (IBM, Armonk, NY, USA) and SPSS AMOS 21.0 software were used to analyze the data.Results: It was found that the confirmatory factor analysis result of FHBS confirmed the original structure of the scale, and Cronbach's Alpha coefficient was calculated as 0.80. A positive correlation was found between the parents' total scores of FNPA and FHBS (r:0.511, p < 0.001).Conclusions: It is recommended to evaluate the child and their parents holistically in preventing and managing childhood obesity. School health nurses should plan family-centered interventions to improve health behaviors and carry out these interventions with a multidisciplinary team. Moreover, it has been determined that FHBS is a valid and reliable measurement tool for the Turkish population.

(Springer Publishing Co, 2024) Seren, Arzu Kader Harmanci; Alan, Handan; Turkmen, Emine; Gungor, Serkan; Baykal, Ulku
Background and Purpose: Assessing student satisfaction is essential in evaluating the quality of education. The number of valid and reliable tools that measure students' satisfaction with online education is limited. This methodological study aimed to assess the psychometric properties of the online education student satisfaction scale. Methods: Eleven academicians from the nursing field provided expert opinions on content validity. Separate 25 students evaluated the language clarity of the draft scale. The study sample included 525 third- and fourth-year nursing students. Finally, a group of 30 nursing students different from the sample participated in the test-retest. The study created an item pool based on the recent literature. The researchers calculated the items' content validity rates and the scale's content validity index by taking the experts' opinions. In addition, item-total score correlation analysis, exploratory factor analysis, discrimination analysis, stability test, and internal consistency analysis were performed. Results: An item with a low-correlation value was excluded from the scale. The correlation coefficients of the remaining items were between .536 and .811. In the second round of exploratory factor analysis, a five-factor structure emerged that explained 72.1% of the total variance. In addition, item discrimination, stability, and internal consistency test results ensured that the scale was valid and reliable. Conclusions: The online education student satisfaction scale with five subdimensions containing 28 items is a valid and reliable tool. Researchers, educators, and managers may use it to evaluate students' satisfaction with online education.

Assessment of the Quality and Reliability of Information on Nutrition After Bariatric Surgery on Youtube
(Springer, 2020) Sevdin, Sezen; Kermen, Seda; Sevdin, Sezen; Yildiz, Nida; Guclu, Duygu; Beslenme ve Diyetetik Bölümü
Background YouTube (TM) is a platform that many people, including patients, use to access health information. Recent studies have revealed that videos on YouTube (TM) are misleading or that medical videos may not contain appropriate information. This study aimed to assess the quality and reliability of videos on nutrition after bariatric surgery. Materials and Methods The keywords "after bariatric surgery diet" and "weight loss surgery postop diet" were used, and the first 100 videos for each keyword on YouTube (TM) were analyzed by considering the source, duration, content, and the number of likes of the video. The popularity of the video was calculated using the video power index (VPI) and view rate. The educational quality of the videos was evaluated using the DISCERN score, the Journal of the American Medical Association (JAMA) score, the Global Quality Score (GQS), the usefulness score, and a novel postoperation nutrition score (PONS). Results One hundred fourteen patients were included in the study. The mean duration and number of views were 12.51 min and 87,558.46, respectively. The DISCERN score, JAMA score, GQS, and usefulness score of the physicians or dietician-based videos were significantly higher than those of the patient-based videos (p < 0.001). Positive correlations were found between the VPI and view ratio, as well as between the duration and number of likes. Additionally, the DISCERN score was significant correlated with the duration and number of likes. Significantly positive correlations were found between the usefulness score and duration, usefulness score and number of likes, and PONS and duration (p < 0.01). Conclusions Informational videos on nutrition after bariatric surgery on YouTube (TM) are of low quality. Although the videos uploaded by physicians and dieticians have higher quality, only a few are available. Additionally, patients prefer to watch low-quality videos.

Balance Training in Modern Dancers Proprioceptive-Neuromuscular Training Vs Kinesio Taping
(Science & Medicine inc, 2018) Tekin, Demet; Agopyan, Ani; Baltaci, Gul; Terapi ve Rehabilitasyon Bölümü
Kinesio tape and proprioceptive exercises are both used for increasing balance in dancers. The purposes of this study were to: a) determine the acute effect of kinesio tape (KT) application on the ankle joint on balance performance, b) investigate the effects of an 8-week proprioceptive-neuromuscular (PN) training program on balance performance, and c) compare their effects vs modern dance technique classes alone. Thirty-three trained, university-level modern dance students (9 male, 24 female) were divided randomly into three groups: kinesio tape (KT, n=11), proprioceptive-neuromuscular (PN, n=11), or control (n=11). Static (turn-out passe-opened eyes/releve and turn-out passe-closed eyes/flat foot), semi-dynamic (airplane), and dynamic balance (monopodalic-straight and -transverse in a turn-out passe-eyes opened/flat foot) tests were performed before and after the intervention. One day after pre-tests, KT mechanical correction technique was applied to the left ankle joint (supporting leg) in the KT group, and tests were repeated to determine the acute effect of KT. The PN group participated in an 8-week balance training program (2 days/wk, 60 min/day) involving exercises using stable and unstable surfaces. Significant improvements were observed for all static and dynamic balance tests in the PN group; semi-dynamic airplane and dynamic monopodalic-straight and transverse tests improved in the KT group; and only semi-dynamic airplane test scores changed significantly for the control group (p<0.05). Our findings suggest that with the exception of the semi-dynamic airplane test, both PN training and KT application were more effective at improving balance performance for modern dancers than modern dance technique classes alone.

(Springer, 2024) Umay, Ebru; Eyigor, Sibel; Demirag, Kubilay; Kaymak Karatas, Gulcin; Gundogdu, Ibrahim; Giray, Esra; Adiguzel, Emre
There is no study about all aspects of oropharyngoesophageal (OPE) dysphagia from diagnosis to follow-up in a multidisciplinary manner in the world. In order to close this gap, we aimed to create a recommendation study that can be used in clinical practice, addressing all aspects of dysphagia in the ICU in detail with the opinion of experienced multidisciplinary experts. This recommendation paper was generated by a multidisciplinary team, using the seven-step process and a three-modified Delphi round via e-mail. Firstly, 15 open-ended questions were created, and then detailed recommendations including general principles, management, diagnosis, rehabilitation, and follow-up were created with the answers from these questions, Each recommendation item was voted on by the experts as overall consensus (strong recommendation), approaching consensus (weak recommendation), and divergent consensus (not recommended).In the first Delphi round, a questionnaire consisting of 413 items evaluated with a scale of 0-10 was prepared from the opinions and suggestions given to 15 open-ended questions. In the second Delphi round, 55.4% were accepted and revised suggestions were created. At the end of the third Delphi round, the revised suggestion form was approved again and the final proposals containing 133 items were created. This study includes comprehensive and detailed recommendations, including a broad perspective from diagnosis to treatment and follow-up, as detailed as possible, for management of dysphagia in patients with both oropharyngeal- and esophageal-dysphagia in ICU.

(Kare Publ, 2024) Dikeç, Gül; Saritas, Merve; Oban, Volkan; Hemşirelik Bölümü
Objectives: In the past two decades, the number of publications on stigma has increased in the literature. This study aimed to conduct a bibliometric analysis of publications related to stigmatization in the psychiatric nursing literature. Methods: In this study, a search was performed on the PubMed database on September 11, 2022, with the Medical Searching Terms "(Stigmatization [Title OR Abstract] OR Social Stigma [Title OR Abstract]) OR (Stigma [Title OR Abstract] OR Stereotyping [Title OR Abstract] OR Discrimination [Title OR Abstract]) AND (Psychiatric Nursing [Title OR Abstract] OR Nursing [Title OR Abstract])." Between 1990 and 2022, 10,571 studies published in English, available in full text, and published in journals indexed with SCI, SSCI, and ESCI were found. Results: The number of published articles reached the highest number in 2020, with an increase of 4.05 times in 30 years; it was determined that 92.8% of the publications were of the descriptive study, and Happell was the most productive author in this field. Frequently, articles were published in the Journal of Psychiatric and Mental Health Nursing (n=762), Journal of Psychosocial Nursing and Mental Health Services (n=550), International Journal of Mental Health Nursing (n=480), Issues in Mental Health Nursing (n=445), and Journal of Advanced Nursing (n=429). It was determined that the top five most frequently repeated keywords were humans, female, psychiatric nursing, male, and adult, respectively. Conclusion: The findings obtained from this study can provide information about the number of publications, research types, researchers, and institutions, as well as give ideas for new research strategies in psychiatric nursing literature. Establishing cooperation between institutions and authors can guide psychiatric nurses in creating projects to reduce stigma.

Can Financial Transactions Reveal the Change in Social Fabric Triggered by Urban Regeneration?
(Elsevier Sci Ltd, 2024) Özbay Daş, Zühal; Dass, Zuhal Ozbay; Ozbay, Ayse Elif Ozsoy; Bozkaya, Burcin; Balcisoy, Selim; Ekonomi ve Finans Bölümü
In this study, we aimed to investigate the relationship between single-building scaled urban regeneration, driven by the Disaster Risk Transformation Law, and urban segregation in Maltepe district. Following stricter building codes, the district underwent significant demolition and construction between 2014 and 2015. We employ construction data and credit card transaction data to analyze the demographic changes. We find that urban regeneration due to building renewal may have diverse context-dependent effects on the demographic tapestry of communities, their culture and history. While some neighborhoods showed positive response to increased local amenities and resulted in reduced mobility outside their local area, leading to greater income segregation from the rest of the city, others behaved in the opposite direction. Similarly, the transformation process has attracted a more educated and higher-income inflow of residents in some neighborhoods compared to others. Herein, we employ new big data and mobility-driven metrics from computational social science such as diversity, loyalty and assortativity to reveal the link between urban regeneration and segregation. Our findings provide important clues and insights to urban planners for developing urban policies leading to neighborhood designs that are more connected to each other (hence reducing segregation) while still offering modern amenities expected by their residents.

Carvacrol Improves Cognitive Dysfunction by Decreasing Amyloid-Β Accumulation and Regulating Neuroinflammation in Ovariectomized Renovascular Hypertensive Rats
(Springer, 2024) Şener, Göksel; Ertas, Busra; Aydin, Yasemin; Sener, Goksel; Eczacılık Meslek Bilimleri Bölümü
Hypertension contributes to both the development and progression of brain damage and cognitive dysfunction in the postmenopausal period in women. Carvacrol (CAR), which can easily cross the blood-brain barrier, exhibits neuroprotective properties due to its antioxidant, anti-inflammatory, and anti-apoptotic effects. In the present study, we have examined the effect of CAR treatment on learning-memory impairment in a post-menopausal hypertensive rat model that was induced by ovariectomy following two-kidney, one-clip renovascular hypertension surgery. From the third week after the establishment of renovascular hypertension in ovariectomized rats, CAR (40 mg/kg) was administered once daily for consecutive 7 weeks by gastric gavage. Systolic blood pressure was estimated by the tail-cuff method once a week. At the end of the study, cognitive functions were evaluated with behavioral tests and also neurochemical changes were measured in serum, cortex, and hippocampus by ELISA test. Blood pressure was decreased with CAR treatment in hypertensive rats. Serum estrogen levels decreased in ovariectomized rats and did not change with CAR treatment. CAR demonstrated beneficial effects on learning and memory tests as determined by increased recognition index, the number of platforms crossed, and time spent in the target quadrant. Due to CAR treatment, there was a marked reduction in the hippocampal and cortex amyloid-beta, osteopontin, interleukin-6 and tumor necrosis factor-alpha levels, and acetylcholinesterase activity, while an increment in neprilysin and interleukin-10 levels was found. In conclusion, since CAR suppressed amyloid-beta deposition and neuroinflammation in ovariectomized-hypertensive rats, it is thought that it may be protective against memory disorders in postmenopausal hypertensive women.

Challenging Discrimination in Different Areas: Turkey
(Peter Lang AG, 2021) Köseoğlu, Nihan; Apak, D.; Siyaset Bilimi ve Uluslararası İlişkiler Bölümü
This book aims to evaluate the issue of discrimination in Turkey from different points of view. Valued academics have addressed issues of discrimination in different fields such as press, sports media, social media, politics, political discourse, immigration, economics, architecture, gender, identity, and violence. Turkey is also encountered in both implicit and explicit examples of discrimination in a way as it is in many other countries. Discrimination can be adopted through discourses and can be reproduced in a wide range from politics to sports, from media to economy and can also be carried over generations. Although legal arrangements have been made against discrimination, discrimination is still active in different parts of society and in different areas. © Peter Lang GmbH Internationaler Verlag der Wissenschaften Berlin 2021.

Combined Spectroscopic and Chromatographic Techniques Augmented With Chemometrics for the Authentication of Black Cumin ( Nigella Sativa L . ) Seed Oil
(Academic Press inc Elsevier Science, 2024) Karaman Ersoy, Şeyda; Ersoy, Seyda Karaman; Kaya, Elif Nilay; Senol, Onur; Apak, Resat; Temel Eczacılık Bilimleri Bölümü
Edible oils adulteration has a great concern because of its health and economical effects. Black cumin seed oils (BCSOs) are one of the most adulterated edible oils. In this case, the purpose of this research was to investigate authenticity of commercial BCSOs by spectroscopic and chromatographic techniques combined with orthogonal partial least square -discriminant analysis (OPLS-DA) and hierarchical cluster analysis (HCA). Sixteen commercial BCSO samples (100 % pure-certified and other BCSOs), potential blending oils (sunflower, corn, and soybean oils), and twenty-one synthetically adulterated BCSO samples blended with sunflower (SFO), corn (CO), and soybean (SBO) oils at levels of 5 %, 10 %, 15 %, 20 %, 30 %, 40 %, and 50 % (v/v) were analysed. Screening of potential fingerprinting markers such as thymohydroquinone (THQ), thymoquinone (TQ), carvacrol (CRV), tocopherol isomers ( alpha-, gamma -, and delta -), as well as total antioxidant capacity and phenolic content analysis were carried out utilizing spectrophotometric CUPRAC, ABTS, and Folin Ciocalteu ' s assays. Commercial pure and fraudulent BCSOs and synthetically adulterated samples were successfully classified in OPLS-DA graphs with 95 % confidence level. Even to five percent detection limit for SFO, CO and SBO adulteration were prominently monitored. In consequence, the proposed spectroscopic and chromatographic methods seem to be a practically applicable, sensitive and versatile protocol that can be used as an alternative fingerprinting procedure to determine adulteration of commercial BCSOs.

Comparative Cross-Sectional Study on Sexual Function of Couples During Pregnancy: Assisted Reproductive Techniques Versus Spontaneous Conceptions
(Womens Health & Action Research Centre, 2024) Dinmez, Sinem; Dinmez, Sinem; Torun, Sebahat D.; Osmanoglu, Usame O.; Ebelik Bölümü
This study aims to compare the sexual functions of couples undergoing assisted reproductive techniques (ART) with those conceiving spontaneously during pregnancy. A total of 102 couples participated in this cross-sectional study, with 68 couples in the spontaneous conception group and 34 couples in the ART group. Data collection was conducted face-to-face in the antenatal clinic using separate "Descriptive Information Form" for women and men, "Female Sexual Function Index (FSFI)" for women, and "Libido Scoring System (LSS)" for men. Descriptive statistical methods, Chi-square and Fisher exact tests, t-test, and Pearson correlation test were used for data analysis. It was observed that the mean FSFI total scores of women who conceived spontaneously and through ART during pregnancy were at a good level (>= 30), while the mean LSS scores of their partners were at a moderate level (5-7). No statistically significant distinction existed among the groups. Further research is advisable by adjusting the sample selection criteria, such as gravida, duration of ART treatment, and gestational age.

Comparison of Motorcyclists’ Hand Grip Strength and Reaction Time
(Didactic Asociation Andalucia, 2022) Tekin, D.; Tekin, Demet; Agopyan, A.; Terapi ve Rehabilitasyon Bölümü
The purpose of this study was to compare hand grip strength and reaction times in male motorcycle racers grouped according to different ages and the classes of motorcycle used and determine the relation between these characteristics. Sixty-five healthy male motorcycle racers were divided into four groups according to their age and the power of the motorcycles’ engine: (Group-1 [G1] = 600-CC/23-34 years; Group-2 [G2] = 600-CC/35-48 years; Group-3 [G3] = 1000-CC/23-34 years; Group-4 [G4] = 1000-CC/35-48 years). Then, Nelson’s reaction time and maximal hand grip strength were measured for both hands. There were no significant differences between the groups’ grip strength (p>0.05). It was found that G1’s right-and left-hand reaction time was faster than that of G2, and G1’s left-hand reaction time was faster than that of G3 (p<0.05). The right-hand visual reaction time was found to have a negative weak correlation with the left-hand absolute grip strength (r=-0.247, p=0.047), and there was a weak positive correlation between the left-hand visual reaction time and height (r=0.315, p=0.011). G1’s right-hand visual reaction time was better than that of G2 (p< 0.001), and G1’s visual left-hand reaction time was better than those of G2 (p< 0.034) and G3 (p< 0.011). Although the absolute and relative hand grip strength values did not differ according to the ages and the engine power of the motorcycle used, it was found that the simple reaction time increased with increasing age. © 2022 Didactic Asociation Andalucia.
