Several biomarkers have been developed to track the development of ovarian cancer and identify the illness at an early stage. A promising development for ovarian cancer is using cancer antigen 125 (CA125). The objective of this work is to identify the CA125 marker by utilizing an indium tin oxide polyethylene electrode. The advantage of the designed biosensor is that it is very cheap, disposable, practical, and easy to use. The necessary parameters for the developed biosensor have been optimized in detail. Repeatability, reproducibility, regeneration, storage, and selectivity studies have been completed to characterize the proposed biosensor. Electrochemical impedance spectroscopy and cyclic voltammetry techniques were used for all experimental investigations of the proposed biosensor. The immunosensor offers a large linear detection range (0.01-100 pg/mL). Moreover, this developed sensor has a 0.018 pg/mL limit of detection and a 0.06 pg/mL limit of quantification. The high accuracy of this biosensor was observed in five commercial human serums.
Principles of environmentally sustainable agriculture for building resilient and resource-efficient food systems
(Tubitak Scientific & Technological Research Council Turkey, 2025) Cakmakci, Ramazan; Cakmakci, Songul; Cakmakci, Muhammet Fatih
As the demand for greater quantities of higher-quality food grows with population expansion, climate change, urbanization, and unsustainable agricultural practices accelerate the loss of arable land, ultimately threatening agricultural sustainability. Population growth necessitates a transition to nutritious, safe, and healthy food production systems that ensure higher yields, less reduced waste, improved social outcomes, and the integration of economic, social, and environmental sustainability principles. Urgent global challenges such as resource depletion, biodiversity loss, and climate change necessitate the protection of ecosystems and the sustainable use of natural resources. Agricultural systems must enhance food production and supply productivity, strengthen system resilience, and improve resource efficiency and sustainability. The sustainable development of agricultural systems based on resilience and productivity is important to ensure food security. The aim of this review is to compile, describe, and propose future strategies for promising food systems-including transformative innovations and alternative farming techniques-to facilitate the transition toward resilient, resource-efficient, and sustainable agriculture, and to mitigate long-term challenges. It also provides recommendations for future research, sustainability, resilience, and emerging food trends aimed at promoting sustainable food systems and green technologies, protecting ecosystems, resources, and biodiversity, and optimizing waste management and natural resource use. This article focuses on future sustainable food production and security, environmental protection, alternative protein sources, and innovative agricultural techniques; it highlights scientific and technological advancements, emerging research directions, and offers a comprehensive perspective on resilient, resource-efficient, and sustainable food production systems.
Integrated geochemical, geoelectrical, and UAV-based methods for analyzing the Gzeylülaı landslide Çnkae(aakl, Tükyeri)
(Tubitak Scientific & Technological Research Council Turkey, 2025) Erenoglu, Oya; Ulugergerli, Emin; Erenoglu, R. Cueneyt; Akbas, Abdullah; Erginal, A. Evren
The number of reactivations increased in the G & uuml;zelyal & imath;-Erenk & ouml;y landslide area after 2013 in & Ccedil;anakkale, T & uuml;rkiye, where historical landslide activity has been recorded since 1875. This area is home to numerous summer residences and experiences ongoing slow-moving landslide activity along a 400-m-long slope, extending from the heavily trafficked & Ccedil;anakkale-& Idot;zmir highway to the coastline. In this study, the nature of the reactivations was evaluated by considering the conditioning and triggering factors that contributed to the landslide. The evaluation was based on geochemical analyses, field observations, geoelectric measurements, and unmanned aerial vehicle (UAV) data. The results revealed that the sliding occurred along a moist slip surface, rich in various clay minerals such as illite, montmorillonite, and vermiculite, at a depth of approximately 4.5 m, as determined by ERT (Electrical Resistivity Tomography). Vertical movements within the landslide area, including rises and subsidences, accounted for changes of up to 0.1 m between 2013 and 2023. Chemical Index of Weathering (CIW), Chemical Index of Alteration (CIA), and Plagioclase Index of Alteration (PIA) calculations obtained from the X-ray fluorescence (XRF) spectroscopy analysis indicate that the sliding surface is subjected to strong weathering, and these values are compatible with the X-Ray diffraction (XRD) data.
