Analysis of metalothionein in patients with malignant liver tumors.

Background: Malignant liver tumors are highly aggressive with a poor prognosis. Metalothionein (MT) is a low-molecular intracellular protein, whose primary function is to regulate the homeostasis of heavy metals in many organisms. There are only few studies focusing on the molecular mechanisms of MT expression.

Spectrophotometric and chromatographic analysis of creatine:creatinine crystals in urine.

Creatinine is the end product of the catabolism of creatine and creatine phosphate. Creatine phosphate serves as a reservoir of high-energy phosphate, especially in skeletal and cardiac muscle. Besides typical known changes in serum and urinary creatinine concentrations, rare cases associated with changes in serum and urinary creatine levels have been described in the literature in humans.
