ABSTRACT
This study aimed to evaluate the potential effects of Bisphenol F and S exposure on the skeletal structures of Sprague-Dawley rats. Given the increasing concern about the potential endocrine-disrupting effects of Bisphenol analogs on bone health, this research sought to elucidate their impact in conjunction with Melatonin. Using 80 male Sprague Dawley rats, bones were subjected to a 3-point bending test to assess mechanical properties, and histopathological evaluation was conducted after fixation and decalcification. Statistical analysis was performed using SPSS. The results of the mechanical tests revealed significant differences in deformation and elastic modulus values between groups treated with Bisphenol F+Melatonin and Bisphenol S+Melatonin compared to the control groups. However, the histological images showed no significant differences between the groups. In the discussion, it was noted that the injection of Bisphenol F and Melatonin together increased bone hardness, suggesting that Bisphenol F and Bisphenol S may mitigate the negative effects of melatonin on bone. We attributed the absence of histological differences to the male gender of the studied rats and previous exposure considerations. This study shows that Melatonin can reduce Bisphenol F and Bisphenol S' rapid adjustment effects and increase bone elasticity. The side effects of Bisphenol F and S, as well as the prophylactic effects of Melatonin, can be observed and improved by carefully adjusting the duration, dose, and gender selection.
ABSTRACT
Akabane virus (AKAV) is an arbovirus belonging to the family Bunyaviridae, genus Orthobunyavirus. AKAV consists of three-segment (L, M, and S RNA segments), negative single-stranded RNA. The aim of this study was to investigate an in situ hybridization method (ISH) in a Vero E6 cell line infected with Akabane virus. The 320 base pair amplicon was obtained by RT-PCR with a primer pair and labeled with digoxigenin. Akabane virus RNAs were seen as a granular pattern in the cytoplasm of infected cells. As a result, the expression of the particular Akabane virus gene area was successfully disclosed in the current investigation using the ISH method with a digoxigenin-labeled probe.
ABSTRACT
BACKGROUND: Wound healing involves the repair of skin and other soft tissues after an injury. Royal jelly, a product of bees, possesses antioxidant, anti-inflammatory, antibacterial, and antiviral properties. Melatonin, a circadian indoleamine, is produced in the pineal gland and other organs. This study explores the effects of melatonin and royal jelly, both individually and combined, on wound healing in geriatric and young mice. METHODS: The study includes 90 Balb/C mice divided into ten groups to assess the effects of royal jelly and melatonin on wound healing. Royal jelly was applied topically at a concentration of 300 mg/kg. Melatonin was formulated in a vaseline-based pomade at a concentration of 5 mg/kg. The substances were applied either separately or in combination to wounds created on the mice. RESULTS: Both substances significantly enhanced wound healing at a macroscopic level in both age groups. Melatonin was found to be more effective during the initial wound formation process, whereas royal jelly was more beneficial during the granulation phase. However, significant results at a histopathological level were observed only in geriatric animals. CONCLUSION: The findings suggest a potential new therapeutic approach to enhance wound healing, particularly in elderly individuals. However, these findings need to be supported through further research and clinical trials.
