  Apelin is a hormone with lymphangiogenesis potential, associated with tumor growth and lymph node metastasis, and is reported to stimulate tumor vascularization. This study aimed to investigate the response of the apelin hormone in cattle with and without Enzootic Bovine Leukosis (EBL) infection, based on physiological parameters such as breed, age, and body condition score (BCS). A total of 120 Simmental and Montafon cattle of varying ages (<2, 2-8, and >8) and BCS categories (<2, 3-3.5, and >= 4) were included in the study. Serum apelin hormone levels were measured using the ELISA technique in blood samples collected from the neck vein ( Vena jugularis) of the animals. The analysis of mean serum apelin (ng/mL) values revealed that, among EBL-positive cattle, the highest value was 2.77 ng/mL in Simmental cattle aged 2-8 years with a BCS of 3-3.5, while a value of 2.69 ng/mL was observed in Montafon cattle aged >8 years with a BCS of 3-3.5. For EBL-negative cattle, the highest mean serum apelin value was 2.24 ng/mL, recorded in Simmental cattle aged 2-8 years with a BCS of 3-3.5, whereas it was 1.45 ng/mL in Montafon cattle aged >8 years with the same BCS. In conclusion, this study demonstrated for the first time the effect of apelin hormone levels in cattle with or without EBL, depending on physiological parameters such as age, breed, and BCS. It is suggested that the apelin hormone, which is involved in neoplastic lymphocyte cell infiltration in the lymphoreticular tissues of cattle, and plays a role in regulating tumor growth in EBL, a malignant tumor disease, may contribute to eradication programs. Moreover, the evaluated parameters may prove valuable for disease prevention and control strategies.

  The Relationship of Mitochondrial-derived Peptide (MOTS-c) and Brain Mitochondrial Carrier Protein 1 (BMCP1) Response in Sheep with Some Physiological Parameters

  Bayraktar, B.; Demir, N.; Aksakal, V.

  Background: Mitochondria are organelles called power plants of the cell, which are found in eukaryotic cells and are responsible for the production of energy needed by the cells through aerobic respiration. Mitochondrial dysfunction causes endocrinological, cardiovascular, metabolic and neurodegenerative diseases. The aim of this study was to examine the effects of body condition score (BCS), lactation, pregnancy, age and gender on Mitochondrial-Derived Peptide (MOTS-c) and Brain Mitochondrial Transporter Protein 1 (BMCP1) levels in Akkaraman sheep. Methods: Sheep are classified into 3 categories according to BCS (BCS<2, BCS=3-3.5, BCS≥4). In creating groups in terms of BCS, it was determined by the palpation method applied to the waist area. The sheep included in the study were divided into 4 groups: early lactation, early pregnancy, late pregnancy (dry period) and age (female and male sheep).1st group, ewes in the first period of pregnancy (on the 100th day of the first pregnancy) (n= 30), 2nd group, ewes in the early lactation period (n= 30), 3rd group, ewes in the dry period (the last two months of pregnancy) (n= 30) and in the 4th group, <2 (young) (n=30), 2-8 (adult) (n=30), 8> (old) (n=30), male and female sheep (n=30) of different ages. =180) total of 270 animals. Blood samples were taken from the jugular vein of the sheep before the morning feeding. MOTSc and BMCP1 levels were determined in blood serum samples by ELISA method. Result: In the study, serum MOTS-c and BMCP1 levels in sheep during lactation and pregnancy were determined to be lowest in the VKS<2 group and highest in the VKS ≥4 groups. Likewise, in age and gender groups, the highest level was detected in young lambs and yearlings in the VKS<2 group, while the highest level was detected in old sheep and rams in the VKS ≥4 group. As a result, it was determined that different age, gender, pregnancy and lactation periods affected serum MOTS-c and BMCP1 levels depending on the change in BCS (P<0.05). It was concluded that MOTS-c and BMCP1 may be useful parameters in the evaluation of mitochondrial function, energy metabolism and metabolic profile.

  Effect of kangaroo mother care and white noise on physiological-stress parameters in heel lancing: randomized controlled study

  Kirbaş, Zila Özlem; OdabaşI Aktaş, Elif; Bayraktar, Bülent; Özkan, Hava

  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. Trial Registration: NCT06278441, registered on 19/02/2024.
