Clarification of red grape juice by amine-functionalized magnesium silica aerogel Kara, Ilkay Turhan; Yucel, Sevil; Arici, Muhammet The clarification conditions and the selection of the clarification agent are pivotal in eliminating the haze components from red grape juice (RGJ) while minimizing the loss of functional color components. In this context, we synthesized a water glass-based APTES functionalized magnesium silica aerogel (MSA-NH 3 ) incorporating 61.44 molecules/nm 2 of amine groups, resulting in a positively charged zeta potential value of 33.9 mV (pH 3.4) for clarification of RGJ by targeting negatively charged polyphenols. The optimum clarification conditions using MSA-NH 3 were determined as 0.18 g MSA-NH 3 /L RGJ, 20 degrees C, and 60 min through the application of BoxBehnken design. Under these conditions, MSA-NH 3 exhibited excellent adsorption of haze components (3.61 NTU), outperforming the commercial bentonite-gelatine combination (BGC) (5.45 NTU). Furthermore, it exhibited greater efficacy in preserving anthocyanins while adsorbing browning components. MSA-NH 3 has a high potential to serve as a functional alternative clarification agent in the beverage industry due to its promising clarification performance.

COVID-19 Phobia in Pregnant Women and its Effect on Vaccination Attitude Gebelerde COVID-19 Fobisi ve Aşı Tutumuna Etkisi Akdemir, Arzu; Yakit Ak, Eda; Tandogan, Ozden; Oskay, Umran Objective: Coronavirus disease -2019 (COVID-19) vaccination rates among pregnant women are lower than the general population. This study aimed to determine the impact of COVID-19 phobia and vaccination attitudes among pregnant women. Methods: This descriptive and cross-sectional study was conducted online with 254 pregnant women between May 2022 and December 2022; sociodemographic characteristics, COVID-19 vaccination data, Coronavirus Phobia Scale, and Anti -vaccine Scale of women with pregnancies older than 12 weeks of gestation were compared. Results: Our study determined that 68.5% of pregnant women received COVID-19 vaccination before pregnancy and 4.7% during pregnancy. It was determined that 30% of pregnant women did not know about COVID-19 vaccines. It was determined that there was a significant positive correlation between COVID-19 phobia and anti -vaccination levels. COVID-19 phobia was higher in pregnant women with children and low economic income. It was determined that women who had never been vaccinated had higher levels of anti -vaccination. Conclusion: Lack of information, having children, low economic income, the belief that the vaccine will have adverse side effects on the pregnant woman and her baby, and COVID-19 phobia were associated with low vaccination rates in pregnant women. These factors should be considered to raise public awareness and increase vaccination in pregnant women.

Effect of polycystic ovary syndrome on the life quality of young women Tandogan, Ozden; Ak, Eda Yakit; Akdemir, Arzu; Oskay, Umran; Callioglu, Nihal OBJECTIVE: The study evaluated the opinions of polycystic ovary syndrome on the life quality of women. METHODS: A total of 249 women with polycystic ovary syndrome participated in this descriptive study between October 2022 and July 2023 in Istanbul, Turkey. FINDINGS: Polycystic Ovary Syndrome and Quality of Life was significantly correlated with age (p=0.000) and frequent weight loss diets (p=0.000) (p<0.01). Among the Polycystic Ovary Syndrome and Quality of Life total score and polycystic ovary syndrome symptoms, those with hormone imbalance and insulin resistance had the highest mean scores, while those with menstrual irregularity and fatigue had the lowest. CONCLUSION: Advancing age changes the quality of life of women with polycystic ovary syndrome. To prevent the negative impact of polycystic ovary syndrome on women's quality of life, it is recommended that health professionals develop effective care plans utilizing available evidence.

Intensive care nurses' compassion and patience levels and their attitude towards elderly people Turen, Sevda; Efil, Sevda; Turkoglu, Meryem; Issever, Merve Backgrounds: Intensive care nurses' attitudes towards the elderly and their emotional readiness before giving care can have an impact on the quality of care.Aims: The objective of this study was to investigate intensive care nurses' compassion and patience levels and their attitude towards elderly people.Methods: 'Data Gathering Form', the 'Compassion Competence Scale', the 'Patience Scale and the University of California at Los Angeles Geriatrics Attitude (UCLA-GA) were used.Results: A total of 212 intensive care nurses participated in the study. It was found that nurses whose time working in the intensive care unit and total professional experience were 6 years or more and those who were married and had children had higher levels of both compassion and patience. In addition, patience levels were significantly higher in nurses aged 29 or more. It was found that the nurses' sociodemographic and professional characteristics did not affect their UCLA-Geriatrics Attitudes total score.Conclusion: It was found in the study that there was a significant positive correlation between the nurses' compassion and patience levels and their attitudes toward elderly people.
