In this study, research was conducted to predict the probability of cervical cancer occurrence associated with the use of hormonal contraceptives. Cervical cancer is influenced by various environmental factors; however, the human papillomavirus (HPV) is detected in 99% of cases, making it the primary attributed cause. Additionally, although cervical cancer ranks 10th in overall female cancer incidence, it is nearly 100% preventable among known cancers. Early-stage cervical cancer typically presents no symptoms but can be detected early through regular screening. Therefore, routine tests, including cytology, should be conducted annually, as early detection significantly improves the chances of successful treatment. Thus, we employed artificial intelligence technology to forecast the likelihood of developing cervical cancer. We utilized the logistic regression algorithm, a predictive model, through Microsoft Azure. The classification model yielded an accuracy of 80.8%, a precision of 80.2%, a recall rate of 99.0%, and an F1 score of 88.6%. These results indicate that the use of hormonal contraceptives is associated with an increased risk of cervical cancer. Further development of the artificial intelligence program, as studied here, holds promise for reducing mortality rates attributable to cervical cancer.

The aim of this study was to analyze the antioxidant properties of different cultivars of grape skin extract in an in vitro system. The extracts were prepared from eight grape cultivars: ‘Campbell Early’ (CE), ‘Kyoho’ (K), ‘New Kyoho’ (NK), ‘Muscat of Alexandria’ (MOA), ‘Seibel’ (S), ‘Morgen Schow’ (MS), ‘Gold Finger’ (GF), and ‘Meru’ (M). The total phenolic acid contents were highest in MS and K. Resveratrol content was high in NK (50.88 mg/1 g of coat), and quercetin content was significantly higher in K (0.68 mg/1 g of coat) than in the other grape species (0.21-0.44 mg/1 g of coat). The K and MS grape species, in which total phenol content was comparatively high (K: 24.15 μg/mL, MS: 25.52 μg/mL), also showed a high level of electron donating activity (K, 53%; MS, 59%). The hydrogen radical scavenging activity of M (50.36%) was significantly higher than the other grape species, including the S (50.21%), MS (49.43%), and K (49.06%) cultivars. Antioxidant activity varied depending on grape species, but overall it was highest in the MS and K cultivars.
