RESUMEN

BACKGROUND: Circumcision is a surgical operation that is frequently performed throughout the world due to religious, cultural, and medical reasons. The best age for circumcision is still debatable, with different procedures depending on geography, culture, and surgeon preference. OBJECTIVE: This study aims to immunohistochemical examination using S100 staining and histologically evaluate the neurovascular structures in foreskin samples obtained from children aged 0-3 years and 6-11 years. The goal is to provide guidance in determining an appropriate age for circumcision based on these data. STUDY DESIGN: Concerns regarding potential effects on glans sensitivity and sexual function led to the investigation and comparison of sensory innervation in the foreskin of children aged 0-3 and 6-11 years, a total 54 samples, divided into pre-phallic (0-3 years) and post-phallic (6-11 years) groups, were examined. The mean number of Meissner and Pacinian corpuscles, Ruffini endings, free nerve endings and the diameters of arteries were investigated. RESULTS: Our findings show that compared to the 6-11 age group, the 0-3 age group had considerably lower sensory innervation in terms of, Meissner's corpuscles, Pacinian corpuscles, Ruffini endings and free nerve endings. Additionally, the diameter of arteries was noticeably smaller in the 0-3 age group. CONCLUSIONS: In conclusion, this study supports the idea that circumcision performed in the early years of life may be associated with less adverse effects on neurovascular structures.

RESUMEN

Background/aim: This study aimed to determine the proliferation and apoptotic effects of extracts from Cornus mas L. and Berberis vulgaris fruits on human breast cancer cells (MCF-7). Materials and methods: The Cornus mas L. and Berberis vulgaris fruits, which constitute the herbal material of the study, were turned into 80% acetone extract after washing. The total phenolic content in Berberis vulgaris fruit extracts was determined calorimetrically using Folin-Ciocalteu reagent. The spectrophotometric method was used to determine the total flavonoid amount of the extracts. In order to measure the antioxidant capacity of Cornus mas L. and Berberis vulgaris fruits and extracts, DPPH Radical Scavenging Power test and Cu (II) ion reducing antioxidant capacity method were applied. Cell viability rates were determined by the XTT method. Flow cytometric measurement was performed to examine the apoptotic role of the extracts in the cell by using the Annexin-V/7-AAD commercial kit. Results: According to the data, Berberis vulgaris fruit extract appeared more effective on MCF-7 breast cancer cells in both 24 and 48 hours of exposure. Analyses made to examine the phenolic component and antioxidant capacity properties of the fruits used in the study and the results we encountered when we exposed the cell were found to be compatible with each other. Annexin-V/7-AAD method showed that the apoptotic effects of the extracts in 48 hour exposures were more effective. Conclusion: It has been determined that Cornus mas L. and Berberis vulgaris fruits, which are rich in phenolic components with high flavonoid content and high antioxidant capacities, support the apoptosis of cancer cells.
