previous reports showed that elevated levels of glucocorticoids following morphine withdrawal play an important role in memory impairment. in addition, glucocorticoid receptor (gr) inhibitors improved memory perfor-mance in morphine withdrawal mice. since mineralocorticoid receptor (mr) and grs complement each other, the aim of the current study was to evaluate the effects of spironolactone on ...

To evaluate the significance of the renal resistive index (RI) as a noninvasive marker of renal histological damage and a prognostic indicator, we examined RI by Doppler ultrasonography in 202 chronic kidney disease (CKD) patients who underwent renal biopsy. RI increased as the CKD stage progressed and correlated with age, systolic blood pressure, estimated glomerular filtration rate (eGFR), an...

A partir disto, argumentamos que é...

Extracellular proteases of Porphyromonas gingivalis specific for arginyl peptide bonds are considered to be important virulence factors in periodontal disease. In order to determine the number, inter-relationship and kinetic properties of these proteases, extracellular enzymes with this peptide-bond specificity were purified and characterized from P. gingivalis W50. Three forms, which we denote...
