OBJECTIVE: To investigate the influence of commercial peritoneal dialysate (CDS) on function of macrophage. METHODS: Cultured peritoneal macrophages were divided into two experimental groups and their controls.(1) Macrophages were cultured in conditioned culture medium containing 50%CDS (0.139 mol/L glucose) for 24 h. (2)Macrophage were exposed to CDS containing 0.139mol/L glucose for 10, 30 and 60 min respectively, and then cultured in CDS-free medium for 24 h. The nitric oxide (NO) production and MTT in two groups were measured. In each control group, CDS was replaced by same amount of culture medium. RESULTS: NO production and MTT reduction ability (related to cell viability) of experimental groups were remarkably lower than those of controls and the NO production and MTT reduction in 60min CDS-exposed group were lower than that of 10 min and 30 min CDS-exposed group. CONCLUSION: Dialysate may have detrimental effects on viability and other function of macrophage and these effects may related to time length of CDS exposure.

Umbu-caja and soursop from the Northeast region of Brazil are rich in nutrients and bioactive compounds and are widely processed by the fruit agroindustry. However, there is a lack of research examining the composition and nutritional/technological potential of these co-product fruits. The present study evaluated the nutritional and technological characteristics of umbu-caja and soursop co-product flours (UCF and SCF, respectively), in addition to cytotoxicity in healthy cells.

Breast cancer is the most common type of cancer in women worldwide. A common approach to cancer treatment in clinical practice is to use a combination of drugs to enhance the anticancer activity of drugs while reducing their side effects. In this regard, we evaluated the effectiveness of combined treatment with gemcitabine (GCB) and arsenic (ATO) and how they affect the cell death pathway in cancer cells.

Background/objectives: DNA vaccines are rapidly produced and adaptable to different pathogens, but they face considerable challenges regarding stability and delivery to the cellular target. Thus, effective delivery methods are essential for the success of these vaccines. Here, we evaluated the efficacy of capsules derived from the cell wall of the yeast as a delivery system for DNA vaccines.

Some specific anthraquinone derivatives (AQs) are known to be used widely as effective chemotherapeutic agents in the treatment of cancer. However, their fundamental shortcoming is the high rate of cardiotoxicity observed in treated patients, which is thought to be caused by the increase in production of reactive oxygen species (ROS) catalyzed by iron and copper. The development of improved AQs and other anticancer drugs with enhanced efficacy but reduced toxicity remains a high priority.

The Chansu injection (CSI), a sterile aqueous solution derived from Chansu, is applied in clinical settings to support antitumor and anti-radiation treatments. CSI's principal active components, bufadienolides (≥90%), demonstrate potential effects on pancreatic cancer (PDAC), but their underlying mechanisms remain unclear. This study aimed to elucidate the antitumor effects and pathways associated with CSI in PDAC.
