Kırbaş, Zila Özlem; Bayraktar, Bülent; Aktaş, Elif Odabaşı
This study aimed to determine salivary cardiac troponin I and cortisol hormone levels in primary school students to evaluate the cardiac response depending on age and gender variables. The sample of the study consisted of a total of 180 children, including boys and girls aged 8, 9, and 10 years old. The ELISA technique determined cTnI and cortisol hormone levels in saliva samples taken from the children included in the study. There was a significant difference between the salivary cTnI levels and the age levels of the children in the groups (p<0.001). A significant difference was found between the mean level of salivary cortisol hormone and the gender and age variables of the child (p<0.001). As a result of the study, a positive, weak, and statistically significant correlation was found between salivary cTnI and cortisol hormone levels (p<0.05). In the model created for the dependent variable of saliva cTnI, it was found that 7.5% of the variance was explained by the independent variables (R2 adjusted=.075), and the age variable was a statistically significant positive predictor (p<0.001). In the model created for the dependent variable of cortisol hormone, it was found that 48.4% of the variance was explained by the independent variables (R2 adjusted=.484), and age and gender were positive statistically significant predictors (p<0.001). Within the scope of the data obtained in our current study, it was determined that cortisol hormone levels were also high in children with high salivary cardiac troponin I levels. It is thought that examining and monitoring cardiac troponin I and cortisol hormone levels may be useful parameters in the nursing care and practice of children with heart disease risk and disease.

Glossophobia (fear of public speaking, presentation anxiety) is an anxiety disorder characterized by extreme fear and anxiety about public speaking. Glossophobia is a very common phobia worldwide, reportedly affecting 75% of the population. This study aims to examine the effects of different aroma inhalations (Thyme and Juniper) on public speaking anxiety, and salivary cortisol hormone levels in university students. The sample of the research consisted of a total of 104 university students, male and female, between the ages of 18-20. In the first step, cortisol hormone levels were determined using the ELISA technique in the saliva samples taken from the university students included in the study. The average salivary cortisol hormone level and public speaking anxiety levels of the university students participating in the study showed a positive and statistically significant relationship (p=0.001). There is a significant negative correlation between the participants' public speaking anxiety and post-thyme oil status at a 99% confidence level and a 1% significance level, r=-.318. When public speaking anxiety and juniper oil were analyzed, a significant negative relationship was found at r=-.290, a 99% confidence level, and a 1% significance level. It was also concluded that inhalation of 2% thyme essential oil in individuals with high glossophobia is both safe and beneficial in reducing anxiety levels.

Orthorexia nervosa (ON) is a type of eating disorder marked by an excessive preoccupation with eating healthily to preserve and promote health, which surpasses normal levels of concern. This study aims to investigate the correlation between orthorexic tendencies, anthropometric measurements, and several other characteristics among university students. A cross-sectional study was done with a sample size of 307 university students from various departments, consisting of 228 females and 79 males. The data-gathering process consisted of administering a demographic information form and the ORTO-11 questionnaire. Anthropometric measurements, such as weight, height, waist circumference, hip circumference, and chest circumference, were measured. In addition, Body Mass Index (BMI) was calculated. The TANITA BC-418 equipment was used to measure the weight of the participants, while a flexible tape measure was used to measure their height, waist circumference, hip circumference, and chest circumference. The BMI was calculated by the individual's weight (in kilograms) by the square of their height (in meters). The data analysis encompassed the utilization of descriptive statistics, t-tests, variance analysis, and Pearson correlation analysis. A score of 25 or lower on the ORTO-11 scale was categorized as orthorexic, whereas a score higher than 25 was deemed normal. The average age and orthorexia scores of the subjects were 20.81±1.86 and 27.76±4.42 for females, and 21.38±4.14 and 28.11±4.37 for males, respectively. It was determined that 29.3% of the participants were found to display orthorexic tendencies, while the remaining 70.7% did not. There were no statistically significant variations in age, hip circumference, and orthorexia scores across genders (p>0.05). No statistically significant relationship was found between the total orthorexia scores and BMIs of the individuals (r=-.051, p>0.05). ON is associated with psychological and social complications, which in turn contribute to the development of disordered eating patterns. The results of this study indicate that determining the frequency of orthorexic tendencies among university students may contribute to the development of strategies for its prevention.

Kirbaş, Zila Özlem; Bayraktar, Bülent; Aktaş, Elif Odabaşi
Background: Adolescence is the period in which physical and emotional changes occur through hormones, the individual acquires gender characteristics and prepares for the adult role psychologically and physically. Dysfunctional attitudes are beliefs and attitudes that can lead to depression by causing negative thoughts about oneself, others, and the future.Dysfunctional attitudes negatively affect children’s mental health. Hormones have a significant impact on human behavior and cognitive functions. However, little is known about the role and influence of hormones on dysfunctional attitudes. Apelin is a hormone responsible for controlling emotions by regulating emotional behavior. The level of dysfunctional attitudes is one of the important issues in nursing practice in terms of protecting and improving children’s mental health. However, little is known about the role and impact of hormones on dysfunctional attitudes.This study aimed to examine adolescents’ dysfunctional attitudes and salivary apelin hormone levels in terms of sociodemographic variables. Methods: The study was conducted in a relational screening model with 151 adolescents aged 9–14 years who were reported to be clinically healthy in Türkiye. Apelin hormone levels were analyzed by ELISA technique in the saliva samples of the participants. In the evaluation of dysfunctional attitudes, the relationship between the score obtained from the dysfunctional attitude scale and salivary hormone levels was evaluated. Results: In the study, a negative, strong and statistically significant correlation was found between the average salivary apelin hormone level and dysfunctional attitudes of adolescents (p =.000). Mean salivary hormone levels of apelin in adolescent girls and boys were 0.696 (SD 0.052) ng/ml, respectively; while 0.671 (SD 0.047) ng/ml was determined (p =.002), dysfunctional attitudes scale scores were 52.95 (SD 14.43); it was determined as 59.04 (SD 14.22) (p =.006). On the other hand, the highest average salivary apelin hormone level (p =.038). and the lowest level of dysfunctional attitudes were determined in adolescent girls aged 13–14 years (p =.028). Conclusions: In our study, we found that while the salivary apelin hormone levels of adolescents decreased, their dysfunctional attitudes increased. We found that adolescents’ dysfunctional attitudes decreased with age. In contrast, apelin hormone levels increased with age.

Purpose: Little is known about the relationship between apelin and serotonin in emotion regulation. This study aimed to examine children’s emotional regulation skills and salivary apelin and serotonin levels. Methods: This is a cross-sectional study performed in Türkiye. The research was completed with the participation of 146 children, 8–10 years old, from the general population. Emotion Regulation Skills Scale for Children (CERS) was used to assess children’s levels of emotion regulation skills. Apelin and serotonin levels were examined by ELISA technique in saliva samples obtained from children. Results: A statistically significant correlation was found between the mean total score of the CERS and the mean apelin and serotonin levels (p ˂.01). We found that females had higher emotion regulation skills compared to males, older higher than younger ones (p ˂.01). The regression analysis results show that age and gender together explain 50.5% of the variance in CERS scores, while apelin and serotonin together explain 35.8% of the variance. When all four variables (age, gender, apelin, and serotonin) are included in the model, they explain 51.3% of the variance in CERS scores. Conclusion: Older age and female gender explained most of emotion regulations skills.Key points It was determined that the average salivary apelin and serotonin levels increased with increased age, and with increased age ERS also increased. More research is needed as this is the first time that the relationship between emotion regulation skills and serotonin and apelin levels has been examined.

A chronic microbial infection that is mediated by the host's immune system is the cause of periodontal disease. As the world's population grows, phytotherapy is a therapeutic strategy that makes use of a renewable resource that can provide less costly medicines. This study aimed to investigate the therapeutic effects of eugenol administration on periodontitis by examining the effects of eugenol at different doses biochemically, histopathologically, and radiologically in rats with experimental periodontitis. Thirty-two Sprague Dawley male rats were divided into four groups: 1. the healthy control group (CG), 2. The experimental periodontitis group (PG), 3. The experimental periodontitis+10 mg/kg eugenol group (EG10), and 4. the experimental periodontitis+20 mg/kg eugenol group (EG20). Alveolar bone loss was measured using micro-CT imaging. The TNF-α, IL-6, leptin, asprosin, and apelin levels were analyzed in the serum samples of rats. Histological and immunohistochemical analyses were performed. The data were analyzed statistically. The serum TNF-α, IL-6, leptin, asprosin, and apelin levels were found to be statistically significantly lower in the eugenol-applied groups (EG10 and EG20) than in the PG (p < 0.05). There was a statistically significant difference in the TNF-α, IL-6, leptin, asprosin, and apelin levels between the EG10 and EG20 (p < 0.05). In the measurements made using micro-CT imaging, alveolar bone loss was found to be at the lowest FR1 level, and in histopathological analysis, the least inflammation was observed in the EG20. It was concluded that the application of 20 mg/kg eugenol in rats with experimental periodontitis was a safe dose, was beneficial in alleviating bone loss, and had a positive effect on the healing process.

Background: Newborns are exposed to varying degrees of stressful interventions due to procedures such as heel lancing used in routine metabolic screenings. It is an examination of the effects of white noise and kangaroo care on some physiological parameters and stress markers (cortisol and glucose-regulated protein 78-GRP78) in heel lancing in newborns. Methods: Randomized controlled study was conducted at a gynecology service of a hospital between January and September 2023. 90 babies were divided into three groups: 30 babies in the Kangaroo Care Group (KCG), 30 babies in the White Music Group (WMG), and 30 babies in the Control Group (CG). All babies were randomly divided into groups. Stress parameters were measured by saliva collection method and physiological parameters by saturation device. Results: A statistically significant difference was determined between the total crying time, pulse and saturation values according to the groups (p < 0.001; p = 0.001). A statistically significant difference was determined between the mean values of cortisol and GRP78 measurements according to group and time interaction (p < 0.001). KCG was more effective in reducing total crying time and stabilizing pulse, saturation, salivary cortisol, GRP-78 values compared to WNG and CG. Conclusion: It was concluded that white noise and kangaroo care help reduce newborns’ stress in the case of heel lancing. Practical implications: The practice of kangaroo care and the use of white noise methods may assist healthcare professionals as supportive methods in stress management during invasive procedures.

The aim of the present study was to evaluate the treatment potential of Punica granatum L. peel powder in an experimentally induced sepsis model in rats. Sepsis was induced in 10-week-old, male, Wistar Albino (n=24) rats. The animals were divided into four groups: Sham-operated (S) Group, Control (C) Group, Treatment-1 (T1) Group, and Treatment-2 (T2) Group. To induce the sepsis model, the cecal ligation and puncture procedure was performed. The P. granatum peel powder (200 mg/kg; per os) was applied one hour before (T1) and 10 hours after (T2) surgery in a volume of 2 mL. At the end of the experimental procedure, microbial and histopathological analyses were performed. The histopathological scores on the liver, lungs, heart, kidney, spleen, and pancreas were evaluated. Escherichia coli, Staphylococcus aureus and E. coli + S. aureus were isolated from blood cultures. Severe bacteria were detected in the blood of the group C animals. It was found that there were fewer bacteria in groups T1 (n=2) and T2 (n=4) compared with group C. There were no lesions in the pancreas tissues of any groups. Vascular changes, degeneration, and necrosis were common in the organs in all cases of group C compared to group S. The findings in group T1 were similar to those in group C, however, it was seen in fewer animals. It was determined that there was a general improvement in group T2, and in addition the existing lesions were moderate in severity. In conclusion, P. granatum L. peel powder prevented CLP-induced lung injury in experimental rats. Thus, P. granatum L. peel powder may be an alternative therapeutic agent against lung tissue injury induced by sepsis. The recovery from inflammation was better in group T2 than in the other groups. According to the results of the current study, P. granatum peel powder was found to be effective in the treatment of sepsis with antimicrobial and anti-inflammatory functions.

The aim of this study was to investigate the effect of Lactobacillus reuteri E81 (LRE) probiotic supplementation on heat stress responses in chukar partridges (Alectoris chukar). The birds were divided into two groups, one of which was exposed to heat stress (HS). Within each group, four subgroups, each including 64 birds, were created for the three treatment doses (200, 400 or 600 mg/kg) of LRE and the control. The experiment was started with day-old birds, kept at a temperature of 25 8C or 37 8C. After a 7-day adjustment period, the LRE supplementation lasted for 35 days. The levels of different adipokines, including visfatin (VF), adiponectin (ADP), chemerin (CHEM), as well as the concentration of plasma citrulline (CIT) and the levels of thyroid hormones (T3 and T4) and thyroid-stimulating hormone (TSH) in the blood were measured at 21 and 42 days of age. A significant correlation (P < 0.01) was found between LRE supplementation and the decrease in serum VF, ADP, CIT, T3 and T4 levels in partridges exposed to HS. On the other hand, no significant relationship was found between LRE supplementation and the serum CHEM and TSH levels (P > 0.05). We concluded that the addition of 600 mg/kg LRE is beneficial in preventing intestinal damage and inflammation provoked by HS.

This study was conducted to investigate adipokine [Apelin and brain-derived neurotrophic factor (BDNF)] and cardiac troponin (cTnI) response that emerged after adding an essential oil mixture (EOM) (Eucalytus glabutus labii, Thymus vulgaris, Cymbopogon nardus, and Syzygium aromaticum) at different rates to the drinking water of broilers in which thyroid dysfunction (hypo-and hyperthyroidism) had been experimentally induced. In the present study, 150 1-day-old Ross-308 male broiler chicks were used. They were divided into five groups, each with 30 animals. The groups were designed to include five subgroups: control (C), hypothyroid, hypothyroid + 250 ppm EOM, hyperthyroid, and hyperthyroid + 250 ppm EOM, with six animals in each group. At the end of the experiment, Apelin, p-BDNF, cTnI, T3, T4, and thyroid-stimulating hormone (TSH) levels were investigated in blood serum samples obtained by cervical dislocation from four randomly selected animals from each subgroup, making 100 animals in total. It was found that EOM administration resulted in a dose-dependent increase in p-BDNF and apelin levels, and a decrease in T4 levels in the experimentally induced hypo-and hyper-thyroidism groups, but did not affect T3 and cTnI levels. Conversely, an increase in TSH level was observed in the hypothyroidism groups, whereas a decrease was observed in groups with hyperthyroidism. This study is the first to examine adipokine (Apelin and BDNF) and cTnI response to EOM administration in thyroid dysfunction.

The present study was aimed at investigating the effects of the dietary use of different doses of Moringa oleifera essential oil (MOEO) on performance parameters, internal organ weights and meat quality in Japanese quails (Coturnix coturnix japonica) exposed to Heat Stress (HS). For this purpose, 320 male day-old quail chicks were used. Seven days of preliminary (physical exercise) and a 35-day fattening period were applied. The animals were divided into 8 groups, each including 40 animals according to temparature (C: 25 °C and SC: 37 °C) and dietary doses (C, 200, 400 and 600). Each group was divided into 4 subgroups, each comprising 10 animals. The consequences of this study showed that, in the stress-free (HSF) groups, while all of the different doses of dietary MOEO positively affected growth performance, feed intake and feed efficiency, in the HS groups, similar positive effects were observed with the use of 200 ppm of dietary MOEO. While no effect was detected on internal organ weights on Days 21 and 42 in the HSF and HS groups, a dose-dependent increase was determined in the intestinal pH value on day 42 in the HS group (p <.05). Additionally, in the analysis of meat quality on the 21st and 42 days compared to the controls, no effect was observed on the meat colour parameters value and TBARS level in the HS and HSF groups. Based on the consequences of this study, it is considered that, MOEO could be used as an alternative product in poultry, at a dose of 200 ppm, to reduce the detrimental effects of HS.HIGHLIGHTS Temperature stress, performance parameters and serious problems in the health of poultry. Moringa olifera helps regulate performance parameters in poultry exposed to heat stress. Since the addition of Moringa oleifera to the diets does not affect the organ weight and meat quality in 21 and 42 days, it does not cause any negative effects for the consumer.

The purpose of this study was to examine the effect of adding an essential fatty acid mixture (EOM; Eucalyptus globulus Labill, thymus vulgaris, Cymbopogon nardus, and Syzygium aromaticum) to the drinking water in the heat stress broilers on the adipokine (Apelin, BDNF) response, the histopathologic changes in liver and intestines, and some biochemical parameters. This study lasted for a total of 42days, including the physical exercise period (7days) and the fattening period (35days). A total of 400 Ross 308 male broilers (1-d-old) were randomly divided into 8 groups (50 animals per group), each of which was exposed to various conditions of temperature (C: 22°C and SC: 36°C) and treatment dose (C, 250, 500 and 750mL/1000 L). Each group was divided into 5 subgroups, each comprising 10 animals. In the stress-free groups, whereas the Apelin level linearly decreased, the BDNF level linearly increased. In histopathology, the liver tissue was found to be normal in all groups whereas the duodenum villi length was found to increase in the group of 750mL/1000 L. No statistically significant difference was found between the stressed groups and the non-stressed groups in terms of VLDL, Glucose, Total bilirubin, ALT, and TG (p >.05). While Apelin level increased in the stressed groups, the BDNF level increased in the group of 250mL/1000 L. In the histopathological examination, a small amount of coagulation necrosis was detected in hepatocyte, a diffuse hydropic degeneration was observed in hepatocytes, and finally a dilatation and hyperaemia were seen in sinusoid in the groups of EOM-500mL/1000 L and EOM-750 m/1000 L compared to the control group. Whereas there was no difference between the group of EOM-250mL/1000 L and the control group in terms of duodenum villa length, there was a significant decrease in other groups (p <.00). In conclusion, this study showed that adding 250mL/1000 L of EOM to the drinking water had a positive effect on the serum levels of Apelin and p-BDNF in the groups exposed to stress (p <.05).HIGHLIGHTS Heat stress results in serious annual economic losses in the poultry industry. Essential oil fatty mix acids have positive effects on poultry health. Apelin and BDNF may be a protective factor against deleterious consequences of chronic exposition to heat stress.
