We performed primary immature Sertoli cell culture to investigate whether or not anti-cancer agents would have a direct effect on rat Sertoli cells. Sertoli cells, isolated from testes of 18-day-old rats, were cultured in pellets with medium for 5 days. The concentration of transferrin in cultured medium were measured as the function of Sertoli cells. The anti-cancer agents cis-diamminedichloroplatinum (CDDP), adriamycin and vinblastine were selected for this study, and added to the culture medium. CDDP decreased the level of transferrin concentration in cultured medium, namely 0.5 microgram/ml of CDDP resulted in 54.9% of the transferrin concentration in the medium compared with that without any anti-cancer agents (p < 0.05), and 1.0 micrograms/ml of CDDP produced transferrin concentrations of 57.5% and 46.2% (p < 0.05), respectively. Adriamycin (0.4 microgram/ml) and vinblastine (0.5 microgram/ml) produced transferrin concentrations of 35.2% and 31.3% in cultured medium (p < 0.05), respectively. These findings revealed that anti-cancer agents have direct damaging effects on rat Sertoli cells.

Selenium is an essential element with various industrial and medical applications, hence the current considerable attention towards the genesis and utilization of SeNPs. SeNPs and other nanoparticles could be achieved via physical and chemical methods, but these methods would not only require expensive equipment and specific reagents but are also not always environment friendly. Biogenesis of SeNPs could therefore be considered as a less troublesome alternative, which opens an excellent window to the selenium and nanoparticles' world.

This study focuses on the design, synthesis, and evaluation of benzimidazole derivatives for their anti-tumor activity against A549 and PC-3 cells. Initial screening using the MTT assay identified compound 5m as the most potent inhibitor of A549 cells with an IC of 7.19 μM, which was superior to the positive agents 5-Fluorouracil and Gefitinib.

Purpose: Patients with partial or complete DPD deficiency have decreased capacity to degrade fluorouracil and are at risk of developing toxicity, which can be even life-threatening.
Case: A 43-year-old man with moderately differentiated rectal adenocarcinoma on capecitabine presented to the emergency department with complaints of nausea, vomiting, diarrhea, weakness, and lower abdominal pain for several days. Laboratory findings include grade 4 neutropenia (ANC 10) and thrombocytopenia (platelets 36,000).

Both the surgical non-cultured melanocyte-keratinocyte transplant procedure (MKTP) and intradermal injection of 5-Fluorouracil (5-FU) are effective in the treatment of vitiligo. Intrablisters injection of MKTP was done in one study with better results than MKTP application after ablative CO2 laser of the reciepient area. However, intrablister injection of 5-FU was not done before.
