Steroidogenesis vs. steroid uptake in the heart: do corticosteroids mediate effects via cardiac mineralocorticoid receptors?
Both cortisol/corticosterone and aldosterone accumulate in the cardiac interstitium. The presence of HSD11B2 and mineralocorticoid receptors/glucocorticoid receptors at cardiac tissue sites allows both steroids to exert their effects via separate mechanisms.
Delayed inoculation into selective enrichment broth following a period in transport medium, even with a low inoculum, gave a similar and acceptable GBS detection rate to direct inoculation. Hence, Amies transport medium with charcoal is an appropriate transport medium to use, where it is not practical for clinical specimens to be directly inoculated into selective enrichment broth and as endorsed in the Centers for Diseases Control (CDC) Guidelines, 2002.
