Aktağ, Işıl Gürsul; Cömert, Ezgi Doğan; Gökmen, Vural
This study investigated the impact of sulfuring, various drying methods, and storage with different packaging on the formation of α-dicarbonyl compounds and 5-hydroxymethylfurfural in dried apricots. Changes in the concentrations of α-dicarbonyl compounds, 5-hydroxymethylfurfural, sugars, and color were monitored in the samples (sulfured/non-sulfured, oven-/sun-dried, polyethylene/vacuum/modified atmosphere packaging) during storage at room temperature for 12 months. Among α-dicarbonyl compounds, 3-deoxyglucosone was the most prevalent, reaching 1356.8 ± 70.6 mg/kg dry matter in sulfured oven-dried apricots after drying. Methylglyoxal reached its peak at 723.2 ± 9.9 mg/kg dry matter in sulfured sun-dried apricots after storage. 5-Hydroxymethylfurfural remained at significantly lower levels than the dominant α-dicarbonyl compounds. Both α-dicarbonyl compounds and 5-hydroxymethylfurfural increased significantly during storage, irrespective of packaging, while sulfuring influenced the type of α-dicarbonyl compounds formed. These findings underscore the significance of processing and storage in influencing α-dicarbonyl compounds accumulation, providing valuable insights into maintaining the safety and quality of dried apricots.

Gürçayır, Dilek; Karabulut, Neziha; Söylemez, Nilgün
Purpose: This study investigates not only the impact of first aid training but also how the Teach-Back method influences teachers’ overall epilepsy knowledge, attitudes toward epilepsy, and self-efficacy in managing epileptic seizures. Methods: A total of 166 preschool teachers who filled out the questionnaire form and gave their consent were included in the study between April and June 2022. A quasiexperimental single-group pre-test post-test design was used in the study, Data were collected using the questionnaire form, Epilepsy Knowledge Scale, Childhood Epilepsy Attitude Scale and General Self-Efficacy Scale. The research data were collected by the researchers through face-to-face interviews. Results: It was determined that the rate of correct answers given by preschool teachers to most questions about first aid practices in epileptic seizures increased significantly after the training (p < 0.05). There was a significant improvement in preschool teachers’ first aid practices at the end of the training compared to before the training. The mean score of the Epilepsy Knowledge Scale before the training was 11.16 ± 4.04, after the training was 14.59 ± 2.08, and the difference was statistically significant (p < 0.001). The mean Childhood Epilepsy Attitude Scale score before the training was 47.90 ± 4.02, after the training was 51.53 ± 4.55, and the difference was statistically significant (p < 0.001). Conclusion: Epilepsy education significantly improved teachers’ knowledge and attitudes towards childhood epilepsy. However, the increase in general self-efficacy remained limited. This situation reveals the necessity of practical and long-term programs in addition to theoretical education.

Dogan, Ebru; Altin, Serdar; Guler, Seval Hale; Guler, Omer; Altin, Emine
In this study, a high entropy oxide material was fabricated from its alloy using mechanical alloying technique in the form of (FeNiMnCrV)3O4 with a symmetry of Fd-3m, and their structural properties were investigated by XRD, SEM-EDS dot mapping, and XPS analyses. The EDS analysis results of oxide and alloy show that Fe, Ni, Mn, Cr, and V have similar ratios for both samples. The elemental ratios were also measured by ICP-MS and the results support the EDS and XPS data. The alloy and oxide powders were used for the production of the anode materials for the half-cell configuration of the battery. The CV analysis of both cells showed that they have similar characteristic redox reactions and the main difference between the two electrodes is the current density values in the peaks. The initial capacity value of the (FeNiMnCrV)3O4 for 10 mA/g was found as 1070 mAh/g for the first cycle which is promising results as an anode material for Li-ion cells.

Maulida, Siti; Eriani, Kartini; Fadli, Nur; Siti-Azizah, Mohd N.; Kocabas, Filiz K.; Kocabas, Mehmet; Wilkes, Martin; Handayani, Luvi S.; Rahayu, Sri R.; Muchlisin, Zainal A.
Sperm quality is preserved through the crucial involvement of antioxidants, which play a vital role in minimizing the occurrence of reactive oxygen species (ROS) during the cryopreservation process. The suitability of the type and concentration of antioxidants are species-dependent, and this study is crucial in order to improve the quality of the climbing perch sperm post-cryopreservation. Therefore, this study aimed to determine the best type and concentration of antioxidants for cryopreservation of climbing perch Anabas testudineus sperm. To achieve this, 6 types of antioxidants, namely, ascorbic acid, beta-carotene, glutathione, butylated hydroxytoluene (BHT), myo-inositol, and alpha-tocopherol, with inclusion of a control were tested in 3 replications at three concentration levels of 0 mg/L (control), 20 mg/L, 40 mg/L, and 60 mg/L. Sperm was diluted in a glucose-base extender at a ratio of 1:60 (sperm: glucose base), then 10 % DMSO and 5 % egg yolk was added before cryopreservation for two weeks. The results showed that the type and concentration of antioxidants had a significant effect on the motility and viability of cryopreserved climbing perch sperm (P < 0.05), where the best results for ascorbic acid, beta-carotene, glutathione, myo-inositol, and alpha-tocopherol were obtained at a concentration of 60 mg/L, while BHT was at a concentration of 20 mg/L. The best results for glutathione, myo-inositol, and alpha-tocopherol were significantly different from other treatments, while the best results for ascorbic acid and beta-carotene (60 mg/L) were not significantly different from the 40 mg/L concentration, while the best results for BHT were not significantly different from the control treatments. Therefore, the best concentration of glutathione, myo-inositol, and alpha-tocopherol was 60 mg/L, while for ascorbic acid and beta-carotene it was 40 mg/L, and BHT was not recommended. DNA integrity analysis indicated the absence of fragmentation in all samples, including fresh, control, and treated sperm. Based on practical and economic considerations, myo-inositol at 60 mg/L was recommended for cryopreservation of climbing perch A. testudineus sperm.

Kasimoğlu, Necla; Gürarslan Baş, Nazan
Aim: The aim of this study is to evaluate the relationship between parental attitudes toward childhood epilepsy and spiritual orientations. Methods: This descriptive study was conducted online between May and July 2022 with 417 parents residing in the eastern part of Turkey. Data were collected using a descriptive information form, the Social Attitudes Scale toward Childhood Epilepsies, and the Spiritual Orientation Scale. The obtained data were analyzed using the SPSS software package, employing descriptive statistics such as frequency, percentage, mean, standard deviation, as well as inferential statistics including independent samples t-test, ANOVA, multiple linear regression and correlation tests. Results: The Total Social Attitudes Scale Score toward Childhood Epilepsies was calculated as 45.10 ± 7.81, and the Spiritual Orientation Scale Score was 89.88 ± 30.30 for parents with an average age of 36.64 ± 8.26. It was found statistically significant and high (p > 0.05) for parents who are female, have a higher level of education, and have previously received education about epilepsy regarding both the Total Social Attitudes Scale Score toward Childhood Epilepsies and the Spiritual Orientation Scale Score. A statistically significant positive correlation was found between the Total Social Attitudes Scale Score toward Childhood Epilepsies and the Spiritual Orientation Scale Score. Conclusion: According to the findings of the research, parents' attitudes towards childhood epilepsy are positive, and their spiritual orientation levels are high. As parents' spiritual orientation levels increase, their positive attitudes towards childhood epilepsy also increase.

Aktağ, Işıl Gürsul; Gökmen, Vural
This study investigated the acrylamide formation in model systems, laboratory-scale produced apple juice concentrates obtained from different stages of process, and commercial apple juice concentrates at different Brix levels during the storage. Changes in the concentrations of reducing sugars, asparagine, 5-hydroxymethylfurfural, 3-deoxyglucosone, and acrylamide were monitored. In addition, Schiff bases of 3-deoxyglucosone and 5-hydroxymethylfurfural with asparagine were confirmed using high-resolution mass spectrometry in order to understand the contribution of intermediates to acrylamide formation. The results revealed that acrylamide formed in both acidic-aqueous model systems and laboratory-scale apple juice concentrates during production. The concentrations of 3-deoxyglucosone, 5-hydroxymethylfurfural, and acrylamide increased significantly (p < 0.05) with the increase in Brix levels whereas asparagine levels decreased in commercial apple juice concentrates during storage. The concentration of acrylamide reached at the maximum level of 0.30 ± 0.02 µmol/kg dry matter in 70°Bx of the concentrates. The findings showed that long-term storage of apple juice concentrates at high Brix levels contributes the acrylamide formation even in unsuitable systems such as acidic and high moisture medium. The confirmation of Schiff base of 3-deoxyglucosone and 5-hydroxymethylfurfural with asparagine demonstrated that the acrylamide formation was attributed to the accumulation of intermediates leading to the conversion of asparagine to acrylamide.

Aktağ, Işıl Gürsul; Hamzalıoğlu, Aytül; Gökmen, Vural
This study aimed to survey the content of Maillard reaction products in different UHT-treated milk products and to assess how formation of these products and lysine blockage is affected by the composition. For this purpose, different commercial UHT milks including milk (whole, semi-skimmed and skimmed), lactose-hydrolyzed, protein-fortified, lactose-hydrolyzed protein fortified and follow-on infant milks were analyzed. Among the Maillard reaction products, dicarbonyl compounds, 5-hydroxymethylfurfural, furosine, N-ε-carboxymethyllysine and N-ε-carboxyethyllysine were monitored. The results showed that fortification of UHT milks with protein and carbohydrates as well as hydrolysis of lactose promoted the Maillard reaction. Among the dicarbonyl compounds, 3-deoxyglucosone formation, which was the dominant dicarbonyl compound in milks, varied between 3.12–12.67 mg/L, 13.45–21.98 mg/L and 4.59–40.38 mg/L in lactose hydrolyzed, lactose-hydrolyzed protein-fortified and follow-on infant milks whereas it was 0.22-0.40 mg/L in milks, respectively. Similarly, 5-hydroxymethylfurfural could not be detected in milks, whereas mean 5-hydroxymethylfurfural concentration was found to be 56.3 mg/L and 31.5 mg/L in protein-fortified milks and lactose-hydrolyzed protein-fortified milks, respectively. Accordingly, % blocked lysine, furosine, N-ε-carboxymethyllysine and N-ε-carboxyethyllysine content of different UHT milks were found to be significantly higher than milks (p < 0.05). This is the first study reporting the Maillard reaction products in protein-fortified and infant milks.
