Abstract	The aim of this paper is to review some studies conducted with different learning areas in which the schemes of different participants emerge. Also it is about to show how mathematical proofs are handled in these studies by considering Harel and Sowder's classification of proof schemes with specific examples. As a result, it was seen that the examined studies were addressed in the learning areas of Analysis, Geometry, Algebra, Linear Algebra, Elementary Number Theory, Probability, Combinatorics, and MIX. Students in early grades tend more towards external and empirical proof schemes. On the other hand, the characteristics of the proof schemes become more sophisticated as the participants' profiles change to pre-service teachers or as they become more specializing in mathematics. Some results are as follows: the academic achievement levels, genders, and grade levels of the participants in the studies examined in this paper have indicated that they have similar traces with the schemes they use. In addition, it has been determined that new perspectives such as examining Harel and Sowder's classification with new lenses, revealing the overlooked roles of some dynamics in proof, or improving the framework provide an important research area in terms of revealing students' potentials.

Abstract	One of the major problems in food science is meeting the demand of the world's growing population, despite environmental limitations such as climate change, water scarcity, land degradation, marine pollution, and desertification. Preventing food from going to waste and utilizing nutritive by-products as food rather than feed are easy and powerful strategies for overcoming this problem. Rice is an important staple food crop for more than half of the world's population and substantial quantities of rice bran emerge as the main by-product of rice grain milling. Usually, rice bran is used as animal feed or discarded as waste. Although it is highly nutritious and comprises many bioactive compounds with considerable health benefits, the rapid deterioration of bran limits the exploitation of the full potential of rice bran. Hydrolytic rancidity is the main obstacle to using rice bran as food, and the enzyme inactivation process, which is termed stabilization, is the only way to prevent it. This study reviews the methods of stabilizing rice bran and other rice-milling by-products comprising rice bran in the context of the efficiency of the process upon storage. The effect of the process on the components of rice bran is also discussed.

Abstract	Cancer antigen 125 (CA125) and human epididymal secretory protein 4 (HE4) are critical biomarkers for ovarian cancer diagnosis and progression monitoring; therefore, sensitive determination of their levels in body fluids is crucial. In recent study, label-free CA125 and HE4 immunosensors were prepared using disposable screen-printed carbon electrodes modified with reduced graphene oxide, polythionine, and gold nanoparticles for the sensitive, fast, and practical determination of CA125 and HE4. Differential pulse voltammetry, square wave voltammetry, and electrochemical impedance spectroscopy methods were used for the electrochemical determination of antigens in four different linear ranges (1-100 pg mL

Abstract	Introduction Online learning provides a ubiquitous and self-paced learning experience, while face-to-face learning encourages commitment in a prescheduled formal instruction. Blended learning (BL) combines these two mediums and provides flexible learning opportunities. While faculty development programs have utilized these two mediums separately, BL has not been fully implemented locally until recently. Identifying elements that enable or hinder faculty within a newly implemented BL program can enhance the learning experience and support professional development. The current study aims to identify how junior and senior faculty members of medical departments at a Turkish university perceive enablers and barriers in a new BL faculty development program. Methods This research is a multiple case study with qualitative inquiry using in-depth interviews and thematic analysis. Using a BL approach, the research team designed faculty development activities based on the Four-Component Instructional Design model. Participants accessed the activities on a Moodle learning management system. Faculty experiences in blended faculty development were examined. The study group consisted of 26 participants, with 14 junior faculty in case 1 and 12 senior faculty in case 2 from different medical departments at a Turkish university. Data were collected and analyzed using qualitative methods. Results This study identified enablers and barriers within a BL faculty development program. While participants identified three barriers, they identified eight enabling elements in a BL program. A lack of time was the most critical barrier to participation in the program. Setting goals for personal development and obtaining skills in teaching were essential enablers within the BL program. Conclusion The use of an online platform to support face-to-face faculty development programs is beneficial in several ways for faculty. Faculty developers can utilize BL to foster engagement and motivate faculty for increased participation, especially if they seek to mitigate known barriers to a successful BL program. Online communication and activities are suggested to develop communities of practice in the workplace. Strategies to eliminate workload and provide guidance on time management are required for both junior and senior faculty.

Abstract	The study aimed to evaluate the efficacy of a seed film coating with Origanum vulgare Linnaeus essential oil (EO) against Clavibacter michiganensis subsp. michiganensis (Cmm) on tomatoes. Tomato seeds (cv. Rio Grande) coated with different doses of EO derived from O. vulgare were inoculated with Cmm (1.8 × 10<sup>8</sup> CFU/mL). O. vulgare's EO showed a remarkable inhibition effect on the Cmm growth. The EO effect against Cmm was determined based on the parameters, such as the inhibition zone and bacterial population in a seed. The GC-MS analysis of EO showed that carvacrol is the major component (at 74.05%), which may inhibit the bacterial growth. Later, we have expanded our studies to determine the inhibitory effect of the EO's mode of action on the pathogenic bacteria with a molecular docking analysis based on the molecular protein-ligand interaction. The results showed that carvacrol has a strong interaction with the bacterial expansin protein (PDB 4JJO) of Cmm and the qPCR analyses confirmed the effect of the O. vulgare treatment against Cmm. This original approach has the prominent potential to prevent seed transmission of Cmm for seed quality in the world, suggesting a method for paving the way for Cmm disease management.

Abstract	The aim of this single-blinded, randomized controlled study was to determine the effectiveness of vapocoolant spray in reducing pain related to venipuncture in young, healthy male blood donors. The participants were separated into 2 groups by randomization. The donors in the control group (n = 44) were not given any intervention during the blood collection process. Vapocoolant spray was applied to the donors in the vapocoolant spray group (n = 44). The pain score was 1.90 ± 1.47 for the vapocoolant spray group and 3.23 ± 2.21 for the control group, and the difference between the groups was found to be statistically significant (P = .02). The study result showed that the use of vapocoolant spray for pain management is an effective method of reducing pain related to venipuncture during the process of blood donation in young male donors.

Abstract	Background: Leptin is an adipokine encoded by the Ob (obese) gene and predominantly produced by adipocytes. The roles of both leptin and leptin receptor (ObR) in numerous pathophysiological conditions including mammary tumor (MT) development have been reported. Aim: To examine protein expression levels of leptin and its receptors (ObR) including the long form, ObRb, in MT tissue and mammary fat pad of a transgenic mammary cancer mouse model. Further, we investigated whether the effects of leptin on MT development are systemic or local. Materials and methods: MMTV-TGF-α transgenic female mice were fed ad libitum from week 10 up to week 74. Protein expression levels of leptin, ObR, and ObRb were measured in the mammary tissue samples of 74-week old MMTV-TGF-α mice with and without MT (MT-positive/MT-negative) by Western blot analysis. Serum leptin levels were measured by using the mouse adipokine LINCOplex kit 96-well plate assay. Results: Protein expression levels of ObRb were significantly lower in MT as compared to control tissue of mammary gland. In addition, protein expression levels of leptin were significantly higher in the MT tissue of MT-positive mice compared to control tissue of MT-negative mice. However, ObR protein expression levels in tissues of mice with and without MT were similar. Serum leptin levels at different ages were not significantly different between the two groups. Conclusion: Leptin and ObRb in the mammary tissue may play a critical role in the mammary cancer development, while contribution of short ObR isoform may be less important.

Abstract	We identified Myxobolus anatolicus Pekmezci, Yardimci, Yilmaz & Polat, 2014 and 4 novel Myxobolus species from the Anatolian khramulya Capoeta tinca (Cyprinidae) in northern Turkey based on morphology, histology, and phylogenetic analysis. M. karaeri sp. nov. plasmodia were observed in the skin doublets between fin rays, the surfaces of the operculum, the gill arch membrane, and in the skin of the fin base. M. samsunensis sp. nov. plasmodia were observed in epithelial tissue inside and on the surface and midline of the gill filaments. M. cakmaki sp. nov. presented as a typical vascular species, which develops in large plasmodia at the end of the gill filaments. The chondrophilic M. ekingeni sp. nov. was detected by histology inside the cartilaginous gill arch and the cartilaginous gill rays of the filaments. Phylogenetic analysis of small subunit ribosomal DNA sequences revealed that M. karaeri sp. nov. and M. samsunensis sp. nov. were clustered with Myxobolus species that infect gills, scales, and fins of cyprinids. M. cakmaki sp. nov. grouped with Myxobolus species that exclusively infect the gills of cyprinids. No molecular data were available for M. ekingeni sp. nov.

Abstract	The present study aimed to evaluate the effects of SOD (superoxide dismutase)-rich melon feed supplement on some performance parameters, serum biochemical and antioxidant indexes, and meat quality characteristics of weaned Tuj lambs. An independent measures design (between groups) was used to determine these effects of treatment. After one week of the adaptation period, twenty-four weaned lambs at the age of 60 ± 5.0 days with a body weight of 23.14 ± 0.5 kg were divided into two groups, i.e., the control group (CON) fed basal diet and experimental group (EXP) fed with basal diet + SOD-rich melon ( n = 12 per group). The results revealed a decrement in the ( p < 0.05) feed efficiency ratio (5.88 ± 0.40 vs. 6.59 ± 0.86 kg weight gain/kg feed) and higher carcass yield (61.76 ± 0.80 vs. 60.11 ± 1.07%) in the EXP group as compared to the CON group. Additionally, the EXP group showed a significant increase ( p < 0.05) in serum glucose and high-density lipoprotein levels, while there was a reduction in cholesterol, triglyceride, and low-density lipoprotein levels when compared to the CON group. The serum malondialdehyde was lowered (5.53 ± 0.47 vs. 5.98 ± 0.79 mmol/L) significantly ( p < 0.05), while glutathione concentration was higher ( p < 0.05) in the EXP group (17.82 ± 1.51 mmol/L) when compared to the CON group (16.54 ± 1.59 mmol/L). The cooking loss was also significantly ( p < 0.05) lower in the EXP group when compared to the CON group. In conclusion, the results indicate that SOD-rich melon supplement (30 g/ton of the concentrate feed) can considerably improve carcass yield, some serum biochemical parameters, and meat quality characteristics in Tuj lambs. Thus, the supplementation of lamb diets with a SOD-rich melon additive may be used as an effective nutritional approach to improve their performance and health.
