A study conducted by researchers at Shaheed Beheshti University of Medical Sciences in Tehran, Iran, has found that cooking, particularly frying, contributes significantly to indoor air pollution. The study focused on the production of carbonyls, specifically acetaldehyde (ACT) and acrolein (ACR), during the frying process. The researchers conducted a meta-analysis of 10 papers and found that the pooled concentration of ACT and ACR emitted during frying was 0.079 and 0.154 mg/m3, respectively. The study also estimated the inhalation exposure and health risks associated with these compounds, as well as their potential to form ozone. The research concluded that there is a potential cancer risk associated with ACT and ACR exposure during frying. [Extracted from the article]

Researchers at Tarbiat Modares University in Tehran, Iran have conducted a study on tumor growth and drug application in cancer. The study focuses on a free boundary model of tumor growth that includes heterogeneity or different types of tumor cells caused by mutations and different values of drug and nutrient concentrations. The researchers used mathematical modeling and numerical methods to fit the order of fractional derivatives, coefficients, and rates of the model. The study concludes that despite noise, the prediction of the tumor radius is acceptable. This research has been peer-reviewed and published in Mathematical Methods in the Applied Sciences.

TENG devices have unique advantages such as self-powering, lightweight, and flexibility, making them suitable for various applications. The report examines the mechanisms and electrical parameters of different electrical stimulation techniques for cancer treatment, as well as the pros and cons of each method. It also explores recent advancements in the field of TENGs for cancer treatment. The research has been peer-reviewed and provides valuable insights into the potential of TENGs in improving cancer treatment methods. [Extracted from the article]

Researchers from Sharif University of Technology in Tehran, Iran have conducted a study on cancer treatment. They designed a tracking controller to reduce tumor density in the shortest possible time with minimal side effects. The study used a mathematical model of the human body under chemovirotherapy, which included tumor cells, viruses, immune cells, and a chemotherapeutic drug. The researchers found that a discrete controller performed better than a continuous controller, and proposed an optimal treatment schedule with limited drug and virus dosage. The research has been peer-reviewed and published in Scientia Iranica. [Extracted from the article]

A new report from Shahid Beheshti University in Tehran, Iran, discusses the potential of DNA-based logic systems in cancer research. The researchers propose an automatic design flow to facilitate the creation and implementation of large-scale DNA logic circuits, which could be used for early cancer detection. The study highlights the feasibility, accuracy, efficiency, and simplicity of this design flow, suggesting that it could open up new possibilities for researchers in the field. The research has been peer-reviewed and published in Scientia Iranica. [Extracted from the article]

A new study conducted by researchers at Tehran University of Medical Sciences in Iran focuses on the synthesis and biological evaluation of a group of compounds called 12-aryl-11-hydroxy-5,6-dihydropyrrolo[2",1":3',4']Pyrazino[1',2':1,5]Pyrrolo[2,3-d]Pyridazine-8(9h)-ones. The researchers used a synthetic procedure to obtain these compounds and then evaluated their cytotoxic activities against three human cancer cell lines. One compound, the 3-nitrophenyl derivative, showed promising antiproliferative activity against all tested cell lines, particularly against the Panc-1 cell line. The researchers also confirmed the induction of apoptosis and cell cycle arrest in Panc-1 cancer cells by this compound. Further validation was done using the Western blotting assay to assess the inhibition of kinases and induction of cellular apoptosis. [Extracted from the article]
