Concomitant chemotherapy in trimodal treatment of patients with muscle invasive bladder cancer: A systematic review of prospective trials.

Background And Objective: For selected patients with muscle-invasive bladder cancer (MIBC), trimodal therapy (TMT) incorporating transurethral resection of the tumor and chemoradiotherapy is an alternative to radical cystectomy. Concurrent chemotherapy (CC) is a pivotal component of TMT, however, the optimal CC protocol remains unknown. This systematic review aims to assess efficacy and safety outcomes of CC protocols used in TMT.

Effect of nephrotoxic treatment with gentamicin on rats chronically exposed to uranium.

Uranium is a radioactive heavy metal with a predominantly chemical toxicity, affecting especially the kidneys and more particularly the proximal tubular structure. Until now, few experimental studies have examined the effect of chronic low-dose exposure to uranium on kidney integrity: these mainly analyse standard markers such as creatinine and urea, and none has studied the effect of additional co-exposure to a nephrotoxic agent on rats chronically exposed to uranium. The aim of the present study is to examine the potential cumulative effect of treating uranium-exposed rats with a nephrotoxic drug.

Acetaminophen induces xenobiotic-metabolizing enzymes in rat: Impact of a uranium chronic exposure.

The extensive use of uranium in civilian and military applications increases the risk of human chronic exposure. Uranium is a slightly radioactive heavy metal with a predominantly chemical toxicity, especially in kidney but also in liver. Few studies have previously shown some effects of uranium on xenobiotic-metabolizing enzymes (XME) that might disturb drug pharmacokinetic.

Pravastatin limits radiation-induced vascular dysfunction in the skin.

About half of people with cancer are treated with radiation therapy; however, normal tissue toxicity still remains a dose-limiting factor for this treatment. The skin response to ionizing radiation may involve multiple inflammatory outbreaks. The endothelium is known to play a critical role in radiation-induced vascular injury.

Renal anemia induced by chronic ingestion of depleted uranium in rats.

Kidney disease is a frequent consequence of heavy metal exposure and renal anemia occurs secondarily to the progression of kidney deterioration into chronic disease. In contrast, little is known about effects on kidney of chronic exposure to low levels of depleted uranium (DU). Study was performed with rats exposed to DU at 40 mg/l by chronic ingestion during 9 months.
