The prospective association between obesity and major depression in the general population: does single or recurrent episode matter?
Our findings add to the available evidence that obesity might specifically be associated with the onset of multiple episodes of major depression (MDD-R). Although the reverse association was not found, MDD-R tends to be also associated with subsequent development of obesity, but larger studies are needed to fully assess this issue. The heterogeneity of MDD should be considered when examining the effect of obesity on MDD.
Endothelin-3 produces potent gallbladder contraction in vitro, acting mainly via ET(B) receptors and also interacting with ET(A)receptors. The receptors are located on the smooth muscle, but in possum gallbladder, neural receptors may also be involved. These findings suggest that ET-3 may regulate motility of possum and human gallbladder.
