We began analyzing https://www.ahajournals.org/doi/10.1161/01.CIR.103.12.1649, but it redirected us to https://www.ahajournals.org/doi/10.1161/01.CIR.103.12.1649. The analysis below is for the second page.

Title[redir]:
Upregulation of β3-Adrenoceptors and Altered Contractile Response to Inotropic Amines in Human Failing Myocardium | Circulation
Description:
Background—Contrary to β1- and β2-adrenoceptors, β3-adrenoceptors mediate a negative inotropic effect in human ventricular muscle. To assess their functional role in heart failure, our purpose was to compare the expression and contractile effect of β3-adrenoceptors in nonfailing and failing human hearts. Methods and Results—We analyzed left ventricular samples from 29 failing (16 ischemic and 13 dilated cardiomyopathic) hearts (ejection fraction 18.6±2%) and 25 nonfailing (including 12 innervated) explanted hearts (ejection fraction 64.2±3%). β3-Adrenoceptor proteins were identified by immunohistochemistry in ventricular cardiomyocytes from nonfailing and failing hearts. Contrary to β1-adrenoceptor mRNA, Western blot analysis of β3-adrenoceptor proteins showed a 2- to 3-fold increase in failing compared with nonfailing hearts. A similar increase was observed for Gαi-2 proteins that couple β3-adrenoceptors to their negative inotropic effect. Contractile tension was measured in electrically stimulated myocardial samples ex vivo. In failing hearts, the positive inotropic effect of the nonspecific amine isoprenaline was reduced by 75% compared with that observed in nonfailing hearts. By contrast, the negative inotropic effect of β3-preferential agonists was only mildly reduced. Conclusions—Opposite changes occur in β1- and β3-adrenoceptor abundance in the failing left ventricle, with an imbalance between their inotropic influences that may underlie the functional degradation of the human failing heart.

How Does Doi.org Make Money? {💸}

We don't see any clear sign of profit-making.

Websites don't always need to be profitable; some serve as platforms for education or personal expression. Websites can serve multiple purposes. And this might be one of them. Doi.org might be making money, but it's not detectable how they're doing it.
