    Notes: Summary High-performance liquid chromatography (HPLC) was used to separate chlordecone (Kepone), and two of its metabolites, hydrochlordecone and dihydrochlordecone. Elution of the three peaks occured after the solvent concentration reached 100% methanol and was maintained at 100% for approximately five minutes. The method was linear for chlordecone in the concentration range of 10 to 100 μg.

    Notes: Abstract Thirty-three neonatal renal masses were evaluated during a 2-year interval. The final diagnoses in these 33 patients were hydronephrosis [14], multicystic dysplastic kidney [10], renal vein thrombosis [3], obstructed upper pole duplication [2], polycystic kidney disease [2], nephroblastomatosis [1], and mesoblastic nephroma [1]. We recommend an integrated imaging approach that utilizes sonography to clarify anatomy and renal scintigraphy or excretory urography to determine renal function.

    Notes: Abstract Ninety percent of the nation's supply of bentonite is mined in Montana, South Dakota and Wyoming. These lands are difficult to reclaim because of the chemical and physical properties of the soil/spoil material and the arid/semiarid climate of the area. Replacement of the limited topsoil available has shown some benefit but supplies are generally inadequate. The use of inorganic amendments, such as sulfuric acid, gypsum, calcium chloride, vermiculite and perlite, have not shown consistent benefits in plant establishment and growth. Organic amendments; sawmill wood residues, straw and manure, have provided the greatest benefits in the reclamation of bentonite mined lands. Cultural and management practices are important in determining the long-term success of these reclaimed lands. Reclamation technology development for bentonite mined lands is recent and limited and the refinement and application of such technology will depend on increased activity and cooperation among researchers, regulators and the mining industry.
