Despite the availability of various therapeutic approaches, treatment efficacy is often limited by drug resistance and severe side effects. Consequently, there is a growing need for novel and more effective treatment strategies with fewer adverse effects. In recent years, microalgae have emerged as promising sources of bioactive compounds with potential anticancer properties. MCF-7 cells were treated with various concentrations of Tetraselmis suecica extract for 24 h under in vitro conditions. Cell viability was assessed using the 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) assay, while gene expression analysis of apoptosis-related markers (Caspases-3, -8, -9, Bax, Bcl-2, AKT, and PTEN) was evaluated using real-time polymerase chain reaction (RT-PCR). Apoptotic cell death was further evaluated by Annexin V-FITC/PI flow cytometry assay. Treatment with Tetraselmis suecica extract resulted in a dose-dependent inhibition of cell viability, reducing MCF-7 cell survival to 36% at a concentration of 100 mg/mL. The extract significantly upregulated the expression of pro-apoptotic genes (Caspase-3, -8, -9, Bax) and PTEN, while downregulating anti-apoptotic Bcl-2 and AKT. Flow cytometric analysis confirmed enhanced apoptosis in treated cells, with early apoptosis increasing from 0.189% to 8.79% and late apoptosis from 0.45 to 6.9%.These findings suggest that Tetraselmis suecica exerts significant anticancer effects on MCF-7 breast cancer cells by modulating both intrinsic and extrinsic apoptotic pathways.

The scientific communities are searching for more effective strategies to control the condition as a result of its concerning implications. This study introduced and applied a nonlinear mathematical model to analyse the changing conditions of malaria disease transmission within a community. Our research represents a significant advancement in the field of disease prevention by incorporating two additional control factors into the mathematical model that is recommended. These factors are indicative of mosquito pesticide and treatment. Both equilibrium points and the reproduction number (R_{0}) are computed. When (R_{0} < 1), the disease-free equilibrium state is stable both locally and globally. If (R_{0} > 1) and the Routh–Hurwitz requirements are met, the endemic equilibrium point arises and is stable. We illustrate the utility of the model by applying it to the real-world scenario of a disease outbreak in India. We use annual data gathered from 2001 to 2022 from India to optimize the proposed model. This allows for an evaluation of how well the proposed model reflects real-life conditions. The variance in the significance level (R_{0}) was measured using a sensitivity analysis of the LHS-PRCC. The optimum control problem was formulated using Pontryagin’s maximal approach. Using an iterative forward–backward Runge–Kutta fourth order approach, the optimality system was stimulated. The primary findings demonstrate that every control parameter effectively stops the spread of malaria.</div>","PeriodicalId":600,"journal":{"name":"Iranian Journal of Science and Technology, Transactions A: Science","volume":"50 2","pages":"763 - 773"},"PeriodicalIF":1.4,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686701","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}

We have used maximum likelihood and maximum product spacing estimation methods in the classical approach. Bayesian estimation has been obtained under informative gamma prior via likelihood and product spacing function. Moreover, we used the Monte Carlo simulation study to compare the results of all methods. In the third part of this article, we propose two criteria for finding the optimal censoring schemes using the variable neighbourhood search (VNS) algorithm. We obtained the single optimal design using each criterion and the compound optimal design using both criteria simultaneously.

Insect farming is an emerging solution, and Tenebrio molitor (mealworm) is a popular choice due to its ease of rearing, harvesting, and feeding. This study aims to assess how dietary factors affect the body length and weight of T. molitor larvae. Seven diets were prepared, ranging from pure wheat bran (W) as a control to combinations of barley (A, B), chickpea (C, D), and corn (E, F) brans. The type of food significantly influenced the larval and adult insect weight and length. Larvae fed diet W (122.99 mg) and diet D (114.99 mg) showed the highest and lowest weight, respectively. Insects fed with diet W showed the longest length (1.30 cm), while those fed with diet C had the shortest length (1.21 cm). Focusing on the fourth larval stage onwards resulted in low mortality rates. However, diets C (97.7% survival) and B (98.8% survival) exhibited the lowest survival rates. Larval pupation rates differed significantly, with 43.3% of larvae on a 100% wheat bran diet pupating by the 13th instar, compared to 32.9% on a 50% corn bran diet by the 15th instar. These findings emphasize the significant impact of diet on the development of T. molitor. As the global demand for sustainable food sources grows to address future food security challenges, understanding these dietary factors in insect farming is essential.</div>","PeriodicalId":600,"journal":{"name":"Iranian Journal of Science and Technology, Transactions A: Science","volume":"50 1","pages":"223 - 234"},"PeriodicalIF":1.4,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147339917","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}
