To address these limitations, the generalized odd beta prime Generalized (GOBP-G) class of distributions is introduced, along with an extension called the generalized odd beta prime-Weibull (GOBPW) distribution. This new model offers enhanced flexibility and can represent a variety of data characteristics, from symmetric to skewed distributions, as well as diverse hazard rate patterns, such as increasing, bathtub, and decreasing trends. These features make the GOBPW model suitable for statistical analysis in biomedical and engineering applications. This study derives key properties of the GOBPW distribution, including its moments, moment-generating function, entropy measures, stress-strength function, quantile function, and order statistics. The cumulative and probability density functions are also developed, providing a foundational structure for the model. Multiple estimation methods are employed to assess the accuracy and reliability of parameter estimates. Monte Carlo simulations further validate the model's robustness across various conditions. The practical utility of the GOBPW model is demonstrated through applications to three datasets: remission times of 132 bladder cancer patients (CD1), survival times of 73 acute bone cancer patients (CD2), and blood cancer data (CD3). Various evaluation metrics, including Akaike information criterion (AIC), Bayesian information criterion (BIC), Hannan–Quinn information criterion (HQIC), and consistent Akaike's information criterion (CAIC) were used to assess the performance of the competing models. For CD1, the GOBPW model achieves the lowest AIC (381.0622) and BIC (772.1244) among competing models. For CD2, GOBPW again demonstrates superior performance with the lowest AIC (140.2969) and BIC (290.5938), by capturing the extreme value behavior of acute bone cancer survival times more effectively. For CD3, the GOBPW model provides the best fit with an AIC of 65.7700 and BIC of 141.5400, outperforming all other competing models. This research offers a valuable tool for enhanced decision-making in medical data analysis, positioning the GOBPW distribution as a powerful alternative to traditional statistical models.</div></div>","PeriodicalId":17848,"journal":{"name":"Kuwait Journal of Science","volume":"52 3","pages":"Article 100429"},"PeriodicalIF":1.2,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144115933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early GC, which can be multifocal and portend a worse prognosis, is classified into four types: Type-I (protruding), Type-II (superficial), Type-III (excavating), and Type-IV (infiltrating with lateral spreading). This research aimed to explore the possible anti-cancer properties of <em>Stevia rebaudiana</em> ethanol extract (EESR) on SGC-7901 GC cells. We conducted a thorough evaluation of the cytotoxic, anti-proliferative, anti-migratory, and pro-apoptotic effects of EESR, as well as its capacity to regulate the PI3K/AKT/mTOR signaling pathway. We used a range of assays, including 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium-bromide (MTT), clonogenic, Transwell chambers, Annexin-V, Western blotting, and molecular docking analysis, to investigate and understand the molecular pathways responsible for the bioactivity of EESR. The findings of our study showed that the viability of cells, capacity to form colonies, ability to migrate, and ability to invade were reduced in a manner that depended on the concentration of EESR. This decrease was accompanied by the initiation of apoptosis and the suppression of the PI3K/AKT/mTOR signaling pathway. The results showed statistically significant findings, with a substantial decrease (∗∗p &lt; 0.01) in colony formation and migration, as well as an increase in apoptotic cells (∗∗p &lt; 0.01) after EESR treatment. Additional molecular docking studies demonstrated substantial interactions between Stevioside, a crucial component of EESR, and the PI3K-mTOR protein complex. These noteworthy results demonstrate the potential of EESR as a natural therapeutic agent for GC.
