Assessing Antifungal Resistance and Biofilm-Forming Capacity of Candida parapsilosis Isolates from Makeup Sponges
Full text linkCandida parapsilosis, insan derisini ve mukoza zarlarını kolonize edebilen, biyofilm oluşturma yeteneği nedeniyle antifungal tedavilere direnç geliştirebilen fırsatçı bir patojendir. Bu çalışmada makyaj süngerlerinden izole edilen Candida parapsilosis izolatlarının antifungal dirençlilikleri ve biyofilm oluşturma kapasiteleri araştırılmıştır. 46 Candida parapsilosis izolatı arasındaki biyofilm oluşturma kapasiteleri kristal viyole kantitatif yöntemi kullanılarak belirlenmiştir. İzolatlardaki amfoterisin B direnci agar disk difüzyon yöntemi kullanılarak değerlendirilmiştir. Biyofilm üreten türlerin antifungal dirençlilikleri ise gradyan test yöntemi ile değerlendirilmiştir. Kristal viyole analizi sonucunda, izolatların çoğunun zayıf biyofilm üreticisi olduğu 17 izolatın ise orta düzeyde biyofilm üreticisi olduğu belirlendi. Agar disk difüzyon yöntemiyle amfoterisin B'ye karşı izolatların 19,73 ± 1,54 mm ile 23,71 ± 0,70 mm arasında inhibisyon zonu verdiği tespit edildi. Orta düzeyde biyofilm üreticisi olan 17 izolatın ise flukonazol, itrakonazol, klotrimazol, amfoterisin B ve nistatin antifungallerine duyarlı olduğu belirlendi. Çalışmada, makyaj süngerlerinin Candida parapsilosis için rezervuar görevi görebileceğini ve biyofilm oluşturan izolatların antifungal duyarlılığının değerlendirilmesinin önemini vurgulamaktadır. Bu bulgular, kişisel bakım ürünlerinin hijyenik kullanımı ve enfeksiyon kontrol önlemlerinin uygulanması açısından önemlidirCandida parapsilosis is an opportunistic pathogen that can colonize human mucous membranes and skin and develop resistance to antifungal treatments due to its ability to form biofilms. This study investigated the biofilm formation capacities and antifungal resistance of Candida parapsilosis isolates obtained from makeup sponges. The biofilm formation capacities among 46 Candida parapsilosis isolates were determined using the crystal violet quantitative method. Amphotericin B resistance in the isolates was evaluated with the agar disk diffusion method. The antifungal resistances of biofilm-producing species were assessed using the gradient test method. The crystal violet analysis revealed that most isolates were weak biofilm producers, with 17 exhibiting moderate biofilm production. It was determined that the isolates gave inhibition zones between 19.73 ± 1.54 mm and 23.71 ± 0.70 mm against amphotericin B by the agar disk diffusion method. It was concluded that 17 isolates with moderate biofilm production were susceptible to the antifungal agents clotrimazole, fluconazole, itraconazole, amphotericin B, and nystatin. The study emphasizes that makeup sponges may serve as reservoirs for Candida parapsilosis and highlights the importance of evaluating the antifungal susceptibility of biofilm-forming isolates. These findings are significant for the hygienic use of personal care products and implementing infection control measures
3D Bioprinting Strategies for Melatonin-Loaded Polymers in Bone Tissue Engineering
No full textBone pathologies are still among the most challenging issues for orthopedics. Over the past decade, different methods are developed for bone repair. In addition to advanced surgical and graft techniques, polymer-based biomaterials, bioactive glass, chitosan, hydrogels, nanoparticles, and cell-derived exosomes are used for bone healing strategies. Owing to their variation and promising advantages, most of these methods are not translated into clinical practice. Three dimensonal (3D) bioprinting is an additive manufacturing technique that has become a next-generation biomaterial technique adapted for anatomic modeling, artificial tissue or organs, grafting, and bridging tissues. Polymer-based biomaterials are mostly used for the controlled release of various drugs, therapeutic agents, mesenchymal stem cells, ions, and growth factors. Polymers are now among the most preferable materials for 3D bioprinting. Melatonin is a well-known antioxidant with many osteoinductive properties and is one of the key hormones in the brain-bone axis. 3D bioprinted melatonin-loaded polymers with unique lipophilic, anti-inflammatory, antioxidant, and osteoinductive properties for filling large bone gaps following fractures or congenital bone deformities may be developed in the future. This study summarized the benefits of 3D bioprinted and polymeric materials integrated with melatonin for sustained release in bone regeneration approaches.Open access funding provided by Scientific and Technological Research Council of Trkiye (TBIdot;TAK).This work requires no ethical approval or patient consent.

The Concept of Expectation in Behavioral Finance Theory: A Bibliometric Analysis
No full textBehavioral economics is a subfield of economics that reveals how individuals' economic decisions are influenced by cognitive, emotional, and psychological factors. In behavioral economics, individuals are not only seen as actors who interpret economic indicators and make rational decisions but they are also considered in terms of their emotions and motivations. Therefore, behavioral economics investigates how certain emotional and psychological motivations affect economic decisions. Behavioral finance theory, from the same perspective, examines the financial decisions individuals make within the context of psychological and emotional variables. In behavioral finance theory, the most important emotional determinant is the concept of "expectation." In this context, the study investigates how the concept of "expectation" is addressed in studies examining the field of behavioral finance theory using the bibliometric analysis method. This research examines databases such as Web of Science, Scopus, and Google Scholar between the years 1985-2022, based on criteria such as the number of publications, citations, leading authors, countries, and institutions, aiming to reveal the evolution of the concept of expectation over time. In this regard, the study finds that the effects of the concept of expectation in behavioral finance theory have been examined more frequently since the 2000s. These studies primarily focus on risk perception and loss aversion behaviors. © 2025, World Scientific and Engineering Academy and Society. All rights reserved
Bariatric Surgery and Remission of Metabolic Syndrome: A Meta-analysis of Randomised Controlled Trials and Prospective Studies
No full textBackground Studies have discussed the efficacy of bariatric surgery (BS) in remission of individual components of metabolic syndrome (MS). We aimed to analyse the prevalence of MS following BS. Methods On October 5, 2023, we conducted a literature search on PubMed, Scopus, Web of Science, and Cochrane. RevManv5.4 was used for the analysis. Results MS patients who underwent BS had lower odds of MS within the first year post-BS (OR 0.14, 95%CI 0.12-0.17); patients who had a preoperative BMI 42) had lower odds of MS post-BS compared with younger patients (OR 0.05 versus OR 0.17). There was not a difference in MS prevalence between 1 and 2 years postoperatively (OR 1.07, 95%CI 0.72-1.58). Asians reported the highest reduction in MS post-BS (OR 0.08). MS patients who received medical treatment had three times the odds of having MS compared with patients who underwent BS. Patients who had BS reported a decline in their anti-hypertensives and oral anti-diabetic drugs (OR 0.26, 95%CI 0.15-0.46, OR 0.11, 95%CI 0.07-0.16, respectively). There was not a significant difference in MS prevalence between patients who underwent RYGB and those who had SG (OR 2.16, 95%CI 0.74-6.26). Conclusions BS is superior to medical treatment in the remission of MS. Age, preoperative BMI, and country of origin affect the rates of MS remission. BS results in a sustainable resolution of MS across 1, 2, and 5 years post-surgery. A tailored approach is warranted to achieve the best outcomes

Impacts of crowding stress on aquatic animals and its mitigation through feed additives supplementation - a review
No full textThis work is licensed under the Creative Commons Attribution-NonCommercial-NoDerivatives 3.0 License.Continuous and sustainable aquaculture development is essential to provide affordable protein sources for the global population. Nevertheless, the intensification of fish farming at high stocking density led to chronic crowding stress that could impair the growth performance, immune system, and antioxidant capacity of an aquaculture species. Consequently, the prevalence of disease outbreaks increases, resulting in low aquaculture production. Various countries remain highly dependent on antibiotics and chemotherapies to overcome this problem. Recently, researchers have proposed and developed alternative solutions using environmentally-friendly feed additives, such as probiotics, phytobiotics, and synthetic immune stimulants, to mitigate crowding stress. The feed additives reportedly alleviate crowding stress, promote growth performance, enhance gut microbiota, immune system, and antioxidant capacity, and stimulate disease resistance, contributing to the overall improvement of the health status of aquaculture species and boosting aquaculture production. The application of feed additives in aquafeed has been investigated in various aquaculture species to explore their beneficial effects at optimum doses. The study outcomes illustrated that feed additives in aquafeed are promising in mitigating crowding stress among aquaculture species. Herein, this review paper discussed and summarised the impacts of crowding stress on the growth, immune system, and antioxidant capacity of aquatic animals. In addition, this review highlighted the potential of feed additives such as probiotics, phytobiotics, and synthetic immune stimulants in mitigating crowding stress in aquatic animals was highlighted in this review.Matching Grant Universiti Malaysia Kelantan [R/MTCH/A0700/00387A/009/2023/01161]; Ministry of Higher Education, Malaysia under the Niche Research Grant Scheme (NRGS) [R/NRGS/A0.700/00387A/006/2014/00152]This research was funded by the Matching Grant Universiti Malaysia Kelantan(R/MTCH/A0700/00387A/009/2023/01161) and the Ministry of Higher Education, Malaysia, under the Niche Research Grant Scheme (NRGS) (R/NRGS/A0.700/00387A/006/2014/00152)
Spatial distribution and isotopic signatures of N and C in mosses across Europe
No full textThe accumulation of nitrogen (N) in moss tissue has proven to be a reliable marker of increasing N deposition. However, this measurement does not offer additional data about the origin of pollution. In this respect, the analysis of the N isotopic ratios might be a helpful tool in providing supplementary information about the nature of the nitrogenous species in biomonitoring surveys. Furthermore, isotopic signatures have been extensively used in the study of N and carbon (C) biogeochemical cycles. The main purpose of this study was to determine N and C elemental contents and their stable isotopes in mosses to investigate atmospheric pollution patterns across Europe. We aimed at identifying the main N polluted areas and evaluating the potential use of isotopic signatures in the attribution of pollution sources at a regional scale. With these objectives in mind, >1300 samples from 15 countries from Europe, all of them participants of the ICP-Vegetation programme 2005–2006, were analyzed for their C and N contents and ?15N and ?13C. The results were compared to those derived from EMEP model, which provided modeled deposition and emission data, as well as to the predominant land uses at the sampling sites (based on CORINE Land Cover). This evaluation suggests that additional measurements of stable C and N isotopes in mosses could be a valuable tool in European environmental surveys. Such measurements not only provide useful information for identifying probable pollution sources but also enable the quantification of their contributions, serving as biological indicators of significant environmental processes. This study presents the first quantitative assessment of major atmospheric nitrogen (N) sources based on stable isotope analysis on a European scale, establishing a framework for evaluating historical changes in N across the region.Universidad de Navarra; Universidade de Santiago de Compostela, USC; Asociación de Amigos de la Universidad de Navarr
The Individual and Combined Effects of Electrolyzed Water and Chitosan Coating Applications on the Storage Stability of Fresh Strawberries
No full textFresh strawberry is very susceptible to spoilage and has limited storage stability due to its fast metabolism. The main focus of this research was to evaluate if electrolyzed water (EW) (30 ppm or 90 ppm) and 1% chitosan coating can be applied individually and in combination to evaluate individual and synergistic effects on extending the storage stability of fresh strawberries. The samples were analyzed (the gas composition, pH, degrees Brix, weight loss, spoilage rate, texture as well as total anthocyanin and total phenolic composition) for the 5 weeks at 4 degrees C. At the end of storage, the O2 in the trays reduced from 21 to 13% in the groups treated with chitosan, and the CO2 ratio increased from 0.03 to 14%. The most dramatic change in gas exchange, pH, and degrees Brix occurred in the control group during storage. The decrease was less in the chitosan-coated ones. Although there is no linear change in color values (L* and a*), it can be said that EW application has a more conservative feature, especially on a*. At the end of the storage, the combination of chitosan and EW had a spoiled fruit rate of 25-30% by weight, while this rate reached 67% in the control group. The hardness value of strawberries decreases throughout storage. Although there was a decrease in total anthocyanin and total phenolic components during the 5 weeks of storage, the highest protection was measured in samples where chitosan and EW were applied together. As a result of this study, the remarkable synergistic efficacy carried out by the combined application of the chitosan coatings and the EW (30 ppm or 90 ppm) makes it an attractive promising sustainable substitute for artificial preservatives while maintaining their fresh-like quality and improved appeal within the food industry.Scientific and Technological Research Council of Turkiye (TUBITAK)Open access funding provided by the Scientific and Technological Research Council of Turkiye (TUBITAK)
Applications of Equivalent Curves to Ruled Surfaces
No full textIn this paper, the characterization of equivalent curves in E3 is used to define ruled surfaces whose base curves are equivalent curves and to examine the relationships between them. At the same time, an equivalence relation for ruled surfaces is obtained. The equivalence classes resulting from this relation are studied. It is concluded that all ruled surfaces in the equivalence class of a developable surface are developable. Thus, a method is established to obtain an infinite ruled surface from a ruled surface. Finally, a new method is given to obtain a developable surface.anakkale Onsekiz Mart University The Scientific Research Coordination Unit [FDK-2022-4238]This study was supported by Canakkale Onsekiz Mart University The Scientific Research Coordination Unit, Project number: FDK-2022-4238
