Öğe The Effects of Silver Nanoparticles (AgNPs) on Thermophilic Bacteria: Antibacterial, Morphological, Physiological and Biochemical Investigations(MDPI, 2024) Jahan, Israt; Matpan Bekler, Fatma; Tunç, Ahmed; Güven, KemalSince thermophilic microorganisms are valuable sources of thermostable enzymes, it is essential to recognize the potential toxicity of silver nanoparticles used in diverse industrial sectors. Thermophilic bacteria Geobacillus vulcani 2Cx, Bacillus licheniformis 3CA, Paenibacillus macerans 3CA1, Anoxybacillus ayderensis FMB1, and Bacillus paralicheniformis FMB2-1 were selected, and their MIC and MBC values were assessed by treatment with AgNPs in a range of 62.5-1500 μg mL-1. The growth inhibition curves showed that the G. vulcani 2Cx, and B. paralicheniformis FMB2-1 strains were more sensitive to AgNPs, demonstrating a reduction in population by 71.1% and 31.7% at 62.5 μg mL-1 and by 82.9% and 72.8% at 250 μg mL-1, respectively. TEM and FT-IR analysis revealed that AgNPs caused structural damage, cytoplasmic leakage, and disruption of cellular integrity. Furthermore, cell viability showed a significant decrease alongside an increase in superoxide radical (SOR; O2-) production. β-galactosidase biosynthesis decreased to 28.8% level at 500 μg mL-1 AgNPs for G. vulcani 2Cx, 32.2% at 250 μg mL-1 for A. ayderensis FMB1, and 38.8% only at 62.5 μg mL-1, but it was completely inhibited at 500 μg mL-1 for B. licheniformis 3CA. Moreover, B. paralicheniformis FMB2-1 showed a significant decrease to 11.2% at 125 μg mL-1. This study is the first to reveal the toxic effects of AgNPs on thermophilic bacteria.Öğe Advances and applications of nanomaterial-assisted phytoremediation(CRC Press, 2023) Jahan, IsratNanotechnology has the potential to drastically transform the agri-food sector with its significant applications to improve agricultural productivity and the efficiency of agrochemicals. The food sector has benefitted from the inclusion of nanoparticles in food matrixes and the nanoencapsulation of nutraceuticals. Smart packaging mate rials designed with the help of nanotechnology have been used for increasing the shelf life of stored food products. Nanomaterials have been extensively used for the delivery of important agrochemicals to enhance their bioefficacy, prevent their deg radation, and control their release. Various nanomaterials have been explored for remediation of arising environmental issues. Nanotechnology has also made a useful contribution to the utilization of huge agricultural and food wastes for production of valuable products. The existing and emerging applications of nanotechnology will contribute to environmental sustainabilityÖğe Multi-Faceted Evaluation of Psychosocial Function of Elderly Subjects(Cyprus Journal of Medical Sciences, 2022) Vural Doğru, Birgül; Utli, HediyeBACKGROUND/AIMS: With aging, physical, psychological and social changes occur and individuals lose their independence and become semi-or full dependent. Accordingly, physical, psycho-social problems can be seen in the older people and their functionality decreases. For this reason, the study was carried out for the purpose of multidimensional evaluation of cognitive and psycho-social functions of older people. MATERIALS and METHODS: The study was conducted between April 2018 and November 2018. This descriptive and cross-sectional study was performed in two different family health centers in Mardin province. The research was completed with a total of 200 older people who agreed to participate in the study. The data were collected using “Patients Information Form”, “Katz Index of Independence in Activities of Daily Living (Katz ADL)” and “Multidimensional Observation Scale for Elderly Persons (MOSES)”. The number, percent, mean, Mann-Whitney U, Kruskal-Wallis test and Spearman correlation analysis were used in the data analysis. RESULTS: The mean age of participants was 70.03±8.48 years. 54.2% of older people were female and 45.8% were male. The mean score of Multidimensional Observation Scale for Elderly Persons was 24.36±22.38. The mean score of the Katz Index of Independence in Activities of Daily Living was 16.32±3.14. There was a weak positive correlation between age and Multidimensional Observation Scale for Elderly Persons (p<0.001, r=0.43), and a moderate negative correlation was found between Katz Index of Independence in Activities of Daily Living and MOSES (p<0.001, r=-0.56). CONCLUSIONS: This study revealed that older people had high functional and independence levels, and this is due to the fact that older people who come to family health care centers form a sample group. However, multidisciplinary studies periodically are needed to evaluate the cognitive, psychological and social functioning of older people living at home.Öğe Effects of Massage Therapy on Clinical Symptoms of Older People(Journal of education and research in nursing (Online), 2022) Utli, HediyeNurses can improve outcomes of patient care by integrating complementary and alternative therapies with traditional medical practices. Among the non-pharmacological methods that can be used in geriatrics and gerontology are massage, aromatherapy, relaxation, meditation, therapeutic touch, biofeedback (neurotherapy), guided affective imagery (creative psychotherapy), reflexology, acupressure, and naturopathy. Massage therapy attracts the attention of healthcare professionals, patients, and families because it improves many symptoms, it has no side effects, it is easy to learn and apply, and is safe, effective, and economical. Massage therapy is used in geriatric patients for various purposes. For instance, it is effective in the management of pain, agitation, stress, anxiety, worry, and depression, it relieves constipation and improves the range of motion of the joints. Massage therapy together with pharmacological treatments reduces many symptoms of neurological diseases and neurological disease-associated risks, and it has a safe, supportive and positive effect. It is thought that this review, based on the effects of massage therapy, can be a guide especially for nurses working with elderly patients in the neurology clinic.Öğe The effect of acupressure or reiki interventions on the levels of pain and fatigue of cancer patients receiving palliative care: A randomized controlled study(ScienceDirect, 2022) Utli, Hediye; Dinç, Mahmut; Utli, Medical Doctor AdilObjective: Taking pain under control is important to calm the individual and reduce complications. This research was conducted with the aim of determining the effect of Acupressure or Reiki interventions on the levels of pain and fatigue of stage III and IV cancer patients receiving palliative care. Method: The research was a single-blind, repeated measures, randomized controlled study. Research data were collected between February and November 2022. The research sample consisted of Acupressure and Reiki intervention groups and a control group with 52 patients in each group for a total of 156 patients. Acupressure or Reiki was applied to their intervention groups for a total of eight sessions of 20 min each over four weeks, once a day on two days a week. Data were collected by means of a patient description form, an analgesic follow-up form, the Numeric Pain Rating Scale, and the Brief Fatigue Inventory. Results: In comparison with the control group, a significant reduction was seen over time in the levels of pain (p < 0.001), analgesic use (p < 0.001), and fatigue (p < 0.001) in the Acupressure or Reiki intervention groups. Conclusion: Acupressure or Reiki interventions were found to effective in reducing levels of pain, analgesic use, and fatigue.

The Wilcoxon test, Independent Sample t test, One-Way Anova and binary logistic regression were used in the analysis of data. Results: The Diabetes Self-Management Questionnaire (DSMQ) total mean score of the individuals with type 2 diabetes participating in the study during the COVID-19 pandemic was 5.25 ± 1.04. Their anxiety total mean score was 0.32 ± 1.56, and their total mean stress score was 7.06 ± 1.62. Being male, over the age of 65, married and having a diagnosis of diabetes for 6-11 years, increased smoking, the COVID-19 pandemic, reduced physical activity (not walking) and support obtained from health professionals, and increased anxiety and stress levels were found to be risk factors affecting diabetic self-management. Conclusions: The findings show that the COVID-19 pandemic has had a negative effect on the self-management levels of individuals with type 2 diabetes.Öğe Synthesis and characterization of silver nanoparticles decorated polydopamine coated hexagonal boron nitride and its effect on wound healing(Journal of Trace Elements in Medicine and Biology, 2021) Tarhan, Tuba; Şen, Özlem; Emanet Ciofani, Melis; Yılmaz, Deniz; Çulha, MustafaBackground: Wound healing is an essential physiological process involving many cell types and their products acting in a marvellous harmony to repair damaged tissues. During the healing process, cellular proliferation and extracellular matrix remodelling stages could be interrupted by undesired factors including microorganisms and altered metabolic activities. In such a case, the process requires some external stimulants to accelerate or remediate the healing stages. Methods: In this study, we report a multifunctional wound healing stimulating agent. In this context, hexagonal boron nitride (hBN) nanoparticles, silver nanoparticles (AgNPs) and polydopamine(pdopa) were used through mussel-inspired chemistry of dopamine to obtain pdopa coated hBN (hBN@pdopa) and AgNPs decorated hBN@pdopa (hBN@pdopa-AgNPs). These two nanostructures were investigated to observe stages of healing. Results: AgNPs were chosen for inflammation reduction and hBN for induced cell proliferation and migration. In in vitro experiments, firstly, high cellular uptake capacity and biocompatibility of hBN@pdopa and hBN@pdopa-AgNPs were evaluated. They were also tested for their reaction against increased concentration of reactive oxygen species (ROS) in injured cells. Finally, their effect on cellular migration, intracellular tube formation and F-actin organization were monitored by light and confocal microscopy, respectively. Conclusion: The results clearly indicate that the hBN@pdopa-AgNPs significantly decrease ROS production, promote wound closure, and reorganize tube formation in cells.Öğe Suriyeli Mülteci Ergenlerin Yaşadıkları Gelişimsel Sorunların Bazı Demografik Değişkenler Açısından İncelenmesi(İnsan & Toplum, 2020) Apak, Hıdır; Acar, Muhammet CevatBu çalışma, Suriyeli mülteci ergenlerin yaşadıkları gelişimsel sorunları; Milli Eğitim Bakanlığı okullarında okuyan öğrenci görüşleri ışığında ortaya koymayı amaçlamaktadır.
