Performance of a 'Transitioned' Infiltration Basin Part 2: Nitrogen and Phosphorus Removals.

Infiltration basins have been widely used for stormwater runoff management. However, their longevity could be compromised over time, up to the point of operational failure. This research study showed that a 'failed' infiltration basin can 'transition' into a wetpond/wetland-like practice and provide water quality benefits.

Performance of a 'Transitioned' Infiltration Basin Part 1: TSS, Metals, and Chloride Removals.

The water quality performance of a 'failed' stormwater infiltration basin that has 'transitioned' to a wetpond/wetland has been evaluated over a three-year period. Total suspended solids, heavy metals, and chloride in highway runoff and discharge from the transitioned basin were measured during 38 storm events. The transitioned basin provided significant reductions in TSS Event Mean Concentrations (EMCs) and mass in the runoff.

Overexpression of sarcolipin decreases myocyte contractility and calcium transient.

Objective: Sarcolipin (SLN) is a novel 31-amino-acid protein associated with the sarcoplasmic reticulum (SR) whose function in cardiac muscle is poorly defined. In this study, we tested the hypothesis that SLN is a regulator of SR Ca(2+) transport function by overexpressing SLN in adult rat ventricular myocytes which express low levels of SLN.

Methods: Expression of SLN mRNA in rat tissues was analyzed by Northern blot as well by RT-PCR analysis.
