An experiment was conducted to study the influence of three different forms of chromium (CrCl3.6H2O, Na2CrO4.4H2O and Cr2O3) on the utilization of two carbohydrates (glucose and cornstarch) by juvenile hybrid tilapia (Oreochromis niloticus x O. aureus). Average initial body weight

NAD(P)H:quinone oxidoreductase (Nqo1)-mediated detoxification of quinones plays a critical role in cancer prevention. Metals alter the carcinogenicity of AhR ligands, such as TCDD, by modulating the induction of Nqo1, but the mechanism(s) remain unresolved. To decipher the molecular mechanisms involved

A selective oxidation of primary alcohols to the corresponding aldehydes by shaking with chromium trioxide supported on aluminium silicate at room temperature under solvent free conditions is reported. This new procedure can also oxidise secondary alcohols.

This study is concerned with two specific chromium (Cr) exposure situations at a hard-process electroplating company. Its aims are to define variations in urinary Cr concentration and to clarify their exposure relationships. Airborne chromium exposure and urinary excretion were measured
