Work-Related Musculoskeletal Disorders Among Occupational Therapists in Turkey: a Cross-Sectional Study
(Taylor & Francis inc, 2024) Bektas, Selen Aydoner; Degerli, Medine Nur Ozata; Altuntas, Onur; Bumin, Gonca
Work-related musculoskeletal disorders are a common cause of absentism and work disability. As work-related musculoskeletal disorders represent an increasingly important issue for occupational therapists, this study determined musculoskeletal disorders among occupational therapists in Turkey. A total of 238 occupational therapists participated and completed the Nordic Musculoskeletal Questionnaire. As a result, 73.1% of participants reported experiencing neck pain and 72.3% reported experiencing low back pain at 12 months. Statistically significant differences were found between participants with and without work-related musculoskeletal disorders regarding gender, experience, workplace type, treatment, and daily working hours (p < 0.05). Occupational therapists may experience work-related musculoskeletal disorders due to not practicing proper body mechanics or non-provision of transferring equipment.

(Elsevier, 2023) Ede, Seren; Özbeyli, Dilek; Erdogn, Omer; Cevik, Ozge; Kanpalta, Fatma; Ercan, Feriha; Senerg, Goksel
Background and study aims: This study aimed to investigate the possible protective effects of parsley extract (Petroselinum Crispum; PC) against oxidative liver damage caused by bile obstruction in rats. Material and methods: Bile duct ligation (BDL) method was used to induce liver injury in rats. The rats were divided into the three groups each consisting of 8 rats; Sham-operated control (C), bile duct ligated + saline treated (BDL), and BDL + PC treated groups. PC extract was given at a dose of 2 g/kg orally for 28 days. Aspartate amino transferase (AST), alanin amino transferase (ALT), and bilirubin levels were analyzed in sera. In order to determine free radicals in liver injury, luminol and lucigenin chemiluminescence tests used. Oxidative stress was evaluated through superoxide dismutase, glutathione, malondialdehyde, Na+/K+-ATPase and 8-hydroxy guanosine levels. Furthermore, inflammation marker myeloperoxidase, apoptosis marker caspase-3, and fibrosis markers TGF- beta and hydoxyproline were investigated. The liver tissues were also examined for histological evaluations.Results: While PC treatment decreased AST and ALT levels which increased with BDL, oxidant damage parameters also decreased with this treatment. Conclusion: The present study, which is the first research for PC extract on cholestasis induced liver damage, demonstrated that PC extract could be a potential therapeutic agent against liver fibrosis and need further studies.

(International Society of Musculoskeletal and Neuronal Interactions, 2024) Reyhanıoglu, D.A.; Yıldırım, G.; Sengun, I.Ş.; Kara, B.
Objective:To evaluate the use of a computer-based biodex balance exercise system (BBS) on balance, neuropathic pain, clinical presentation and nerve function in patients with diabetic peripheral neuropathy (DPN). Methods: A total of 32 participants with DPN were randomly assigned in a 1:1 ratio to an intervention group (IG) or control group (CG). The IG performed exercises using the BBS twice weekly for 8 weeks, while CG were informed regarding diabetes self-management. At baseline and after study completion, participants underwent balance (postural stability and fall risk) and neuropathic pain assessment (DN4 questionnaire) and were screened using the Michigan Neuropathy Screening Instrument and nerve conduction test. Results: Among the baseline participants, 14 in the IG and 13 in the CG completed the study. Balance training improved postural stability (overall, p<0.001), fall risk (p<0.001), neuropathic pain (p=0.01) and symptoms (p<0.001), and clinical presentation (p=0.02), but not nerve function, within the IG. At follow-up, IG displayed significantly improved stability (p<0.001) and fall risk (p=0.02) and decreased neuropathic symptoms (p=0.01) compared to the CG. Conclusion: Computer-based balance exercises improve balance, pain, and clinical presentation of DPN, but not nerve function, in patients with DPN.

Prevalence of Obesity in Prepubertal and Pubertal With Turkish Population Type 1 Diabetes
(Springer Japan Kk, 2021) Ozkaya, Volkan; Eren, Erdal; Ozgen Ozkaya, Sebnem; Denkboy Ongen, Yasemin
To determine the prevalence of prepubertal and pubertal obesity in children and adolescents with type 1 Diabetes Mellitus (Type 1 DM). One hundred fifty children and adolescents aged 6-18 years with Type 1 DM who attended the Pediatric Endocrinology Polyclinic and were diagnosed with type 1 DM were included in the study. Tanner staging was used to estimate pubertal status. Age- and gender-specific body mass index (BMI) percentile between 85 and 95% was accepted as overweight and > 95% as obese. It was determined that the overweight prevalence rates in children and adolescents with type 1 DM were 13.3% and the obesity rate was 14.3%. It was found that while the overweight prevalence rates (14.1%) were higher in males, the obesity prevalence was higher in females (19.0%). The obesity prevalence rates at the prepubertal and pubertal stages were found to be 17.1% and 13.8%, respectively. The obesity prevalence at the pubertal stage was higher in girls (22.4%) than boys (3.9%) (p < 0.05). The rates both of overweight and obesity in boys decreased from prepubertal to pubertal periods, while those rates increased in girls. Our results indicated that the obesity prevalence in prepubertal and pubertal children and adolescents with type 1 DM was higher compared to healthy peers in the literature. The authors believe that the risk factors for obesity in this population should be determined and obesity-prevention programs for diabetes should be prepared.
Ameliorative Effects of Myrtus Communis L. Extract Involving the Inhibition of Oxidative Stress on High Fat Diet-Induced Testis Damage in Rats
(Taylor & Francis Ltd, 2024) Coskunlu, Busra; Koroglu, M. Kutay; Hersek, Irem; Ertas, Busra; Sen, Ali; Sener, Goksel; Ercan, Feriha
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.

Hepatitis B Immunization Data of Patients Living With Hiv/Aids: a Multi-Centre Study
(Natl inst Public Health, 2022) Ozturk, Servet; Ozel, Ayse Serra; Ergen, Pinar; Senbayrak, Seniha; Agalar, Canan
Objectives: Human immunodeficiency virus (HIV) and hepatitis B virus (HBV) are the two leading viruses that cause the greatest number of virus-related morbidities in the world. HIV/HBV coinfection is correlated with high morbidity and mortality. For this particular reason hepatitis B vaccination is crucial for people living with HIV. Methods: Patients who are being followed-up for HIV/AIDS and who have received a hepatitis B vaccine in 4 HIV clinics over a 5-year time period have been studied. Our multi-centered, retrospective, cross-sectional and observational study investigates factors that affect hepatitis B vaccination immune response of individuals living with HIV. The patients have been studied for the parameters such as age, sex, CD4 count at the time of diagnosis or vaccination, HIV-RNA levels, comorbidities, vaccine dosage, success of immunization after vaccination, and the demographics of the patients who have and have not developed immunity. Results: Of 645 patients that are being followed-up in our clinics, 158 received hepatitis B vaccine; 39 of these 158 patients have been excluded from the study because they did not fulfil the inclusion criteria. Finally, 119 patients were evaluated in the study, 17 of the patients (14.3%) were females and 102 (85.7%) were males. The median age was 41.11 +/- 10.09 (min-max: 18-75). Twenty-three of the patients (19.3%) were at the stage of AIDS during diagnosis while 80.7% were at the stage of HIV infection. Ninety-one of the patients (76.5%) have been administered a single dose hepatitis B vaccine on the standard 0, 1st, 6th month vaccination schedule, whereas 23.5% were administered a double dose on the same vaccination schedule. When further evaluated to find whether the patient was able to develop sufficient immunity (anti-HBs >= 10), it was found that the immune response was statistically significantly higher in the patients whose CD4 count was greater than 200 at the time of the first diagnosis and vaccination (p = 0.05 and p = 0.001, respectively). The patients have also been evaluated according to the number of doses they received (1 vs. 2). The immune response of the patients who received two doses was statistically significantly higher (p = 0.041). Conclusion: We can conclude that in the patients with CD4 count less than 200 at the time of their diagnosis and vaccination a high dose recombinant hepatitis B vaccine should definitely be administered as the normal dose and higher dose have similar side effect profiles and the higher dose provides greater immunity.

A Single-center's Early Surgical Outcomes of Living Donor Liver Transplantation
(Elsevier Science inc, 2023) Anilir, Ender; Oral, Alihan; Atasoy, Alp; Civan, Hasret Ayyildiz; Topcu, Feyza Sonmez; Bayramoglu, Mert; Unal, Bulent
Background. Living donor liver transplantation (LDLT) has become an increasingly common surgical option because the number of cadaveric donors is insufficient to fulfill the organ needs of patients facing end-stage cirrhosis. Many centers are investigating different surgical techniques to achieve lower complication rates. We aimed to examine our complication rates in light of demographic data, graft data, and perioperative findings as a single-center experience. Methods. The study included one hundred and three patients who underwent LDLT for endvein, and bile anastomosis type rates; anhepatic phase; cold ischemia time; operation time; and blood product transfusion rates were analyzed. Biliary complications in patients with single or multiple biliary anastomoses, right or left liver transplants, and with or without hepatic artery thrombosis were analyzed statistically. Results. There was no significant difference in biliary complications between patients who underwent single or multiple bile anastomosis (P = .231) or patients receiving right lobe and left lobe transplants (P = .315). Although there was no statistically significant difference in the rate of portal vein thrombosis between the regular and reconstructed portal vein anastomosis groups (P = .693), the postoperative portal vein thrombosis rate was statistically higher in patients with left lobe transplants (P = .044). Conclusions. Vascular and biliary complication rates can be reduced with increasing experience.

Melatonin Improves Liver and Pancreatic Tissue Injuries in Diabetic Rats: Role on Antioxidant Enzymes
(Springer int Publ Ag, 2023) Ertik, Onur; Bayrak, Bertan Boran; Sener, Goksel; Yanardag, Refiye
PurposeMelatonin (Mel) is an indolamine mainly synthesized by the pineal gland and many other organs. It plays an important role in scavenging free radicals and stimulating antioxidant enzymes. The goal of this study was to investigate the effect of Mel and/or insulin treatment on oxidative liver and pancreas injuries in diabetic rats.MethodsMale Wistar albino rats were assigned into 5 groups. Group I: control animals. Group II: diabetes was induced via a single dose of STZ (60 mg/kg) administered intraperitoneally. Group III: diabetic rats treated with Mel (10 mg/kg/day). Group IV: diabetic rats given insulin (6U/kg) subcutaneously. Group V: diabetic rats that received insulin and Mel at the same dose and time. After 12 weeks of the experiment, the animals were decapitated, liver and pancreas tissues were collected.ResultsThe results indicated that reduced glutathione levels in liver and pancreatic tissue decreased, while protein carbonyl, advanced oxidized protein products and lipid peroxidation levels were elevated in diabetic group. Antioxidant enzyme activities decreased in liver tissues but increased in pancreatic tissues of the diabetic group. Administration of Mel, insulin or Mel + insulin reversed these biochemical changes in the diabetic animals.ConclusionThis work shows that in long-term oxidative stress conditions caused by STZ-induced diabetes, either Mel or Mel + insulin administration may improve the deteriorated oxidant/antioxidant system in both the liver and pancreas tissues. These results suggested that Mel alone or Mel + insulin treatments might have a significant role in protecting against liver and pancreatic damage in STZ diabetic rats via different antioxidant effects.
Unraveling the Persistent Renal Impact of Intrauterine Growth Restriction and Catch-Up Growth: Integrating Morphological Insights with Metabolomic Profiling
(Springer, 2025) Esrefoglu, Mukaddes; Koktasoglu, Fatmanur; Bayindir, Nihan; Cimen, Fatma Bedia Karakaya; Kirmizikan, Seda; Hekimoglu, Emine Rumeysa; Selek, Sahabettin
The study aimed to investigate the long-term effects of IUGR and consequent catch-up growth on metabolic health by using a comprehensive approach that included histopathological, immunohistochemical, biochemical, and metabolomics analyses. Sprague-Dawley pregnant rats either undergo bilateral uterine artery ligation or a sham surgery on the 19th day of gestation. The offspring reached catch-up growth, kidney samples were collected at postnatal weeks 2, 4, and 8 for analysis. IUGR rats exhibited a spectrum of changes including reduced glomeruli number, proliferating cell number, altered oxidative stress markers, various enzymes involved in Krebs cycle, mitochondrial dynamics, and energy metabolism. Examination of the 8-week-old cohort identified a broader spectrum of metabolic alterations, notably in the biosynthesis of phenylalanine, tyrosine, and tryptophan, phenylalanine, tyrosine, glyoxylate, dicarboxylate, pyruvate, alanine, aspartate, and glutamate metabolism, glycolysis/gluconeogenesis and citrate (TCA) cycle. Our metabolomics analysis provides insights into the potential disease susceptibility of individuals born with IUGR, including obesity, diabetes, hypertriglyceridemia, cardiovascular diseases, and mental retardation. These findings underscore the intricate interplay between intrauterine conditions and long-term metabolic health outcomes, highlighting the need for further investigation into preventive and therapeutic strategies to mitigate the risk of metabolic diseases in individuals with a history of IUGR.

Extracorporeal Shockwave Therapy Versus Graston Instrument-Assisted Soft-Tissue Mobilization in Chronic Plantar Heel Pain a Randomized Controlled Trial
(American Podiatric Medical Association, 2022) Pisirici, P.; Cil, E.T.; Coskunsu, D.K.; Saylı, U.; Subasi, F.
Background: Although there are studies showing that extracorporeal shockwave therapy (ESWT) and instrument-assisted soft-tissue mobilization methods are effective in chronic plantar heel pain (CPHP) treatment, there is a need for studies comparing these techniques. We compared the effectiveness of ESWT versus instrument-assisted soft-tissue mobilization using Graston Technique (GT) instruments in addition to stretching exercises (SEs) in CPHP. Methods: Sixty-nine patients were randomly assigned to three groups: ESWT+SEs (group 1), GT+SEs (group 2), and SEs only (control group) (ratio, 1:1:1). The SEs, twice daily for 8 weeks, were standard for all. Group 1 received low-intensity ESWT; in group 2, GT was the selected method. Visual analog scales (for initial step and activity pain), the Foot Function Index (FFI), the 12-item Short-Form Health Survey (SF-12), and the Tampa Scale for Kinesiophobia were used pretreatment, posttreatment, and at 8-week and 6-month follow-up. Results: Visual analog scale and FFI scores improved posttreatment and during follow-up in all groups (P < .001). Although effect sizes were greater in groups 1 and 2 than in the control group in initial step pain posttreatment and at 8-week follow-up, group 2 had the highest effect size at 6 months. Mean SF-12 scores in groups 1 and 2 improved on the post-treatment assessment. Furthermore, group 2 showed significant improvements in FFI scores compared with the other groups at 6-month follow-up (F = 6.33; P = .003). Conclusions: Although ESWT+SEs and GT+SEs seem to have similar effects on initial step pain posttreatment and at 8-week follow-up, GT+SEs was found most effective for improving functional status at 6 months in the management of CPHP. © 2022, American Podiatric Medical Association.

Comparative Cross-Sectional Study on Sexual Function of Couples During Pregnancy: Assisted Reproductive Techniques Versus Spontaneous Conceptions
(Womens Health & Action Research Centre, 2024) Dulger, Ozlem; Dinmez, Sinem; Torun, Sebahat D.; Osmanoglu, Usame O.
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.

The Factors Associated With School Readiness: Sensory Processing, Motor, and Visual Perceptual Skills, and Executive Functions in Kindergarten Children
(Routledge Journals, Taylor & Francis Ltd, 2023) Aydoner, Selen; Bumin, Gonca
Many developmental skills are related to children's school readiness in the early years, and these skills are essential for later achievement. Some of these skills include sensory processing, motor and visual perceptual skills, and executive functions. To date, limited research has examined these skills associated with school readiness. This study investigated the relationship between sensory processing, motor and visual perceptual skills, and executive functions, and school readiness in kindergarten children. A total of 138 kindergarten children administered the Sensory Profile, the Bruininks-Oseretsky Test 2- Brief Form, the Test of Visual Perceptual Skills-3, the Childhood Executive Functioning Inventory, and the Primary School Readiness Scale. The results showed that sensory processing, motor and visual perceptual skills, and executive functions were correlated with children's school readiness, and these skills were also highly predictive of children's school readiness (p < 0.05). It is necessary for future studies to consider these skills when assessing school readiness and to include strategies to develop these skills in intervention programs.
Development and Psychometric Properties of the Self-Efficacy Scale for Symptom Management and Self-Care in Patients with Cardiac Surgery
(Springer Publishing Co, 2025) Aksut, Rabia Saglam; Capik, Canturk; Elmas, Tugce Bozkurt
Background and Purpose: Evaluating self-efficacy for symptom management and self-care is crucial for ensuring follow-up care after cardiac surgery. As there is not yet a validated measurement tool for this evaluation, the aim of this study was to develop the Self-Efficacy Scale for Symptom Management and Self-Care (SESMSC: Cardiac Surgery) in patients with cardiac surgery and to examine its psychometric properties. Methods: The Symptom Management Theory and Bandura's Self-Efficacy Theory were used as the theoretical background for scale development. A multiphase design was utilized. The initial development phase consisted of item generation and expert panel review. The second phase comprised a three-step validation process: (a) face and content analysis (CFA) for construct validity, and (c) Cronbach's alpha, test-retest, and item- total correlation analysis to assess internal consistency reliability. The sample (n = 401) was randomly divided into two subsamples for EFA and CFA (EFA group: n = 201; CFA group: n = 200). Results: EFA suggested a 20-item, two-factor structure with factor loadings of .342-.782. The two subscales of the scale were labeled symptom management self-efficacy and self-efficacy for ch's alpha, test-retest, and item-total correlation results demonstrated acceptable internal consistency reliability. Implications for Practice: The SESMSC: Cardiac Surgery may be a useful tool to evaluate self-efficacy for symptom management and self-care after cardiac surgery. Further evaluation in independent samples is needed to investigate its psychometric properties and usefulness in clinical practice.
Clinical Outcomes of Conservative Versus Surgical Treatment for Patients With Proximal Humeral Fracture Before Physiotherapy
(Acta Medica Belgica, 2024) Kus, G.; Alpozgen, A. Zengin; Gungor, F.; Ozdincler, A. Razak; Altun, S.
Fear of movement, pain, and loss of shoulder function are the most common problems irrespective of their approach to management after proximal humeral fracture (PHF). However, it has been unclear whether there could be differences between both treatments in early clinical outcomes. It can help physiotherapists to guide in choosing treatment approaches. This study aimed to compare kinesiophobia, pain, range of motion (ROM), shoulder function, and Quality of life (QoL) in patients treated with either conservative (CT) versus surgical (ST) after PHF. In addition, it aimed to determine correlations between fear of movement and seconder outcome measures. This cross-sectional study enrolled the patients having 5-6 weeks (being permitted active movement) after being treated either CT or ST and receiving no physical therapy. Pain, passive and active ROMs, shoulder function, fear of movement, and QoL were evaluated. 42 patients were recruited. Kinesiophobia scores were similar (p=0.55) and moderate in both groups. There was a significant difference in degrees of shoulder active flexion, active and passive abduction in favor of the CT group (p=0.05, p=0.02, p=0.04, respectively). However, there was no difference between groups regarding the remaining clinical outcomes. Furthermore, kinesiophobia showed a moderate negative correlation with energy/fatigue, social functioning, and general health. These findings showed that patients treated surgically did not have more kinesiophobia, less function, and QoL before starting physiotherapy, despite having soft tissue damage and different types of fractures. However, surgically treated patients had significantly less range of motion.
Implementation of an AI-Enhanced Motor and Cognitive Intervention: A Case Study in Developmental Delay
(Routledge Journals, Taylor & Francis Ltd, 2025) Bektas, Selen Aydoner; Bumin, Gonca
This study aimed to explore the implementation of an AI-enhanced motor and cognitive intervention for a 7-year-old child with developmental delay. A case study design was employed using an A-B framework (pre-test, intervention, post-test) over 12 weeks. The intervention incorporated AI-based tools such as Lumosity, Just Dance, and Cogmed for tailored motor and cognitive activities. The Bruininks-Oseretsky Test of Motor Proficiency-2 Brief Form (BOT-2 BF) and the Dynamic Occupational Therapy Cognitive Assessment for Children (DOTCA-Ch) were used to evaluate outcomes. Post-intervention, significant improvements were observed in BOT-2 BF and DOTCA-Ch scores, indicating enhanced motor coordination, and cognitive abilities. AI-enhanced interventions demonstrated the potential to address developmental delays by providing adaptive, engaging, and effective therapeutic activities. The findings highlight the feasibility of integrating AI tools into therapy, with implications for broader adoption in addressing developmental challenges. Further research is recommended to explore generalizability and long-term effects.

Assessment of the Psychometric Properties of the Online Education Student Satisfaction Scale: a Methodological Study
(Springer Publishing Company, 2024) Harmancı Seren, A.K.; Alan, H.; Türkmen, E.; Gungor, S.; Baykal, Ü.
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. © Copyright 2024 Springer Publishing Company, LLC.

Comparison of in Vitro Antifungal Activity Methods Using Extract of Chitinase-Producing aeromonas Sp. Bhc02
(Springer, 2023) Cadirci, Bilge Hilal; Yilmaz, Gulesme
Biological control to prevent fungal plant diseases offers an alternative approach to facilitate sustainable agriculture. Since the chitin in fungal cell walls is a target for biocontrol agents, chitinases are one of the important antifungal molecules. In this study, the aim was to investigate a new chitinase isolated from a fluvial soil bacterium and to show the antifungal activity of the characterized chitinase by comparing the three common methods. The bacterium with the highest chitinase activity was identified as Aeromonas sp. by 16 S rRNA sequence analysis. Following the determination of the optimum enzyme production time, the enzyme was partially purified, and the physicochemical parameters of the enzyme were investigated. In the antifungal studies, direct Aeromonas sp. BHC02 cells or partially purified chitinase were used. As a result, in the first method in which the Aeromonas sp. BHC02 cells were spread on the surface of petri dishes, no zone formation was observed around the test fungi spotted on the surface. However, zone formation was observed in the methods in which the antifungal activity was investigated using the partially purified chitinase enzyme. For example, in the second method, the enzyme was spread on the surface of PDA, and zone formation was observed only around Penicillum species among the test fungi spotted on the surface. In the third method, in which the necessary time was given for the formation of mycelium of the test fungi, it was observed that the growth of Fusarium solani, Alternaria alternata and Botrytis cinerea was inhibited by the partially purified chitinase. This study concludes that the results of the antifungal activities depend on the method used and all fungal chitins cannot be degraded with one strain's chitinase. Depending on the variety of chitin, some fungi can be more resistant.
Psychometric Properties and Transcultural Adaptation of Turkish Version of the Basel Assessment of Adherence to Immunosuppressive Medication Scale
(Baskent Univ, 2025) Koken, Zeliha Ozdemir; Ordin, Yaprak Sarigol; Seren, Arzu Kader Harmanci
Objectives: This study aimed to translate BAASIS (Basel Assessment of Adherence to Immunosuppressive Medication Scale) into Turkish and to test the psychometric properties of the translated Turkish version of the instrument. Materials and Methods: In this single-center crosssectional study, we included 100 kidney transplant recipients in a university hospital in a western city of Turkiye. The Translation and Cultural Adaptation Report from Professional Society for Health Economics and Outcomes Research was used for the transcultural adaptation of BAASIS to Turkish. We tested the validity of the BAASIS Turkish version by the level of evidence according to the American Educational Research Association guidelines: content validity, internal structure, and relations to other variables. We calculated item-total correlations of the BAASIS Turkish version to examine internal consistency reliability. Results: The content validity index score of BAASIS was calculated as 1.00, indicating agreement between the experts. Exploratory factor analysis evaluated the internal structure of BAASIS, and the coefficients for inter-item correlations ranged from 0.170 to 0.395. The Immunosuppressive Treatment Adherence Scale and the BAASIS nonadherent scores were significantly correlated (r = 0.673, P < .001). The coefficients for item-total correlation analyses ranged from 0.160 to 0.470. Conclusions: The BAASIS Turkish version has acceptable psychometric properties. The scale can be used in clinical practice and research projects in transplantation to assess immunosuppressive medication adherence.

Effects of Manual Versus Instrumental Spinal Manipulation on Blood Flow of the Vertebral and Internal Carotid Arteries in Participants With Chronic Nonspecific Neck Pain: a Single-Blind, Randomized Study
(Elsevier inc, 2023) Kocabey, Burcu; Coskunsu, Dilber Karagozoglu; Guven, Koray; Agaoglu, Mustafa H.; Yuce, Selvi
Objective: The aim of this study was to compare the hemodynamic effects of manual spinal manipulation (MSM) and instrumental spinal manipulation (ISM) on the vertebral artery (VA) and internal carotid artery (ICA) in participants with chronic nonspecific neck pain (NNP). Methods: Thirty volunteers aged 20 to 40 years old with NNP over 3 months duration were included. Participants were randomly divided into the following 2 groups: (1) MSM group (n = 15) and (2) ISM group (n = 15). Ipsilateral (intervention side) and contralateral (opposite side of intervention) VAs and ICAs were evaluated using spectral color Doppler ultrasound before and immediately after manipulation. Measurements were recorded by visualizing the ICA carotid sinus (C4 level) and the VA at the V3 segment (C1-C2 level). The blood flow parameters of peak systolic velocity (PSV), end-diastolic velocity, resistive index, and volume flow (only for VA) were evaluated. The spinal segment, in which biomechanical aberrant movement was detected by palpation in the upper cervical spine, was manually manipulated in the MSM group. The same methodology was performed for the ISM group using an Activator V instrument (Activator Methods). Results: Intragroup analysis exhibited no statistically significant difference between the MSM and ISM groups in terms of PSV, end-diastolic velocity, resistive index of ipsilateral and contralateral ICA and VA, in addition to volume flow of both VAs preintervention and postintervention (P > .05). Within the intergroup analysis, there was a significant difference in ipsilateral ICA PSV (P = .031) (preintervention vs postintervention difference was -7.9 & PLUSMN; 17.2 cm/s [95% confidence interval, -17.4 to 1.6] in the ISM group and 8.7 & PLUSMN; 22.5 cm/s [95% confidence interval, -3.6 to 21.2]) in the MSM group (P < .05). Other parameters did not show any significant difference (P > .05). Conclusion: Manual and instrumental spinal manipulations applied to the upper cervical spine in participants with chronic NNP did not appear to alter blood flow parameters of the VAs and ICAs.

Objectives: Nutritional obesity causes oxidant damage in the body and cataract formation in the lenses by increasing the formation of free radicals. Myrtus communis leaf extracts (Myr) have antioxidant properties, and apocynin (Apo) is an effective NADPH-oxidase inhibitor. The data on tissue boron levels are quite lacking. The aim of this novel study was to investigate the effects of Myr and Apo treatment on boron levels and oxidative lens damage in rats fed a high-fat diet (HFD). Materials and Methods: Wistar albino male rats were randomly divided into four groups: the control group, HFD group, HFD + Myr group, and HFD + Apo group. Body weight and blood lipids were determined before and after the experiment. After decapitating the rats, the lenses were removed and homogenized. Catalase (CAT) and superoxide dismutase (SOD) activities and boron, malondialdehyde (MDA), and reduced glutathione (GSH) levels in the lens homogenates were determined. Results: The HFD increased serum triglyceride (p<0.05), total cholesterol level (p<0.001), body weight (p<0.001), and lens MDA levels (p<0.01) and decreased lens GSH (p<0.05) and boron level (p<0.01), SOD (p<0.001), and CAT activity (p<0.001). However, Myr and Apo treatment reduced the rats' body weight (p<0.001), serum triglyceride (p<0.05), and total cholesterol level (p<0.001) and increased lens boron (p<0.01; p<0.001), GSH levels (p<0.05; p<0.01), and CAT activity (p<0.001). Conclusion: Both Myr and Apo may be able to reduce oxidative stress in the lenses of obese rats caused by HFD by increasing boron levels.
