Ca and Mg are essential nutrients, and deficiency can cause serious health problems. Thus, lack of Ca and Mg can lead to osteoporosis, with incidence rising both in absolute and age-specific terms, while Mg deficiency is associated with type II diabetes. Prevention via vitamin D or estrogen is controversial, and the bioavailability of Ca and Mg from supplements is significantly lower than that from milk products.

Colorectal cancer (CRC) is a leading cause of cancer mortality, with many patients presenting with malignant colorectal obstruction (MCO). Self-expandable metal stents (SEMSs) have emerged as a minimally invasive key intervention, both as a bridge to surgery (BTS) in curative setting sand for palliation in advanced disease. This review aims to provide an evidence-based analysis of SEMS indications, contraindications, and efficacy across curative and palliative contexts, with focus on long-term outcomes.

Background: The metal oxide nanoparticles possess unique properties such as biological compatibility, superior reactivity, and capacity to develop reactive oxygen species, due to this they have drawn significant interest in cancer treatment. The various MONPs such as cerium oxide, Copper oxide, Iron oxide, Titanium dioxide, and Zinc oxide have been investigated for several types of cancers including brain, breast, cervical, colon, leukemia, liver, lung, melanoma, ovarian, and prostate cancers. However, traditional physiochemical synthetic methods for MONPs commonly include toxic materials, a major concern that raises questions regarding their biocompatibility and safety.

Background: The anticancer activity and radiosensitizing effect of Auranofin, an an-tirheumatic and an approved gold metallic drug, have been investigated from multiple perspectives. In this study, the action of the new gold complex compound TPN-Au(I)-MM4 was compared with that of auranofin.

Methods: The inhibitory effect of 10 μM and 50 μM concentrations on cell proliferation was investigated using the human colon cancer cell lines HCT116 and SW480.

Plastic products contain complex mixtures of chemical compounds that are incorporated into polymers to improve material properties. Besides the intentional chemical additives, other compounds including residual monomers and non-intentionnaly added substances (NIAS) as well as sorbed pollutants are usually also present in aged plastic. Since most of these substances are only loosely bound to the polymer via non-covalently interactions, i.
