BACKGROUND The angiotensin II type 1 receptor (AT2R1) is the receptor for angiotensin II, a potent vasoconstrictor produced by ACE from angiotensin I. A recent study by Biller and colleagues revealed a gender-specific association between the AT2R1 1166 A/C gene polymorphism and disease susceptibility as well as a co-dependent association between AT2R1 1166 A/C and the angiotensin-converting enz...

AIMS (a) To measure infant angiotensin converting enzyme (ACE) activity in healthy term infants at birth and during the first three months of life. (b) To determine the relation between serum ACE activity and infant feeding practice during this period. (c) To investigate the relation between serum ACE activity and birth weight and other potential contributing factors including acid-base status ...

Occurrence of angiotensin converting enzyme (ACE) in mammary gland and tongue taste epithelium was demonstrated for the first time. Six times higher ACE activity in lactating mammary gland, than non-lactating mammary gland, suggested pregnancy and lactation hormonal dependent expression of ACE in female mammals. ACE activity was highest in choroid plexus, less in spinal cord and moderate in cer...

Electrophilic additions of DL- and L-Cys to propenoic acid afforded (RS)- and (R)-2-amino-3-(2-carboxyethylthio)propanoic acids [(RS)- and (R)-ACE], respectively. (RS)-ACE was found to exist as a conglomerate based on its melting point, solubility, and infrared spectrum. (RS)-ACE was optically resolved by preferential crystallization to yield (R)- and (S)-ACE. The obtained (R)- and (S)-ACE were...

The beneficial effect of ACE inhibitors in hypertension and heart failure may relate, at least in part, to their capacity to interfere with bradykinin metabolism. In addition, recent studies have provided evidence for bradykinin-potentiating effects of ACE inhibitors that are independent of bradykinin hydrolysis, i.e. ACE-bradykinin type 2 (B(2)) receptor 'cross-talk', resulting in B(2) recepto...

The purpose of the present study was to investigate the effects on blood pressure and myocardial hypertrophy in SHRs (spontaneously hypertensive rats) of RNAi (RNA interference) targeting ACE (angiotensin-converting enzyme). SHRs were treated with normal saline as vehicle controls, with Ad5-EGFP as vector controls, and with recombinant adenoviral vectors Ad5-EGFP-ACE-shRNA, carrying shRNA (smal...

Attempto Controlled English (ACE) is a controlled natural language specifically constructed to write software specifications. ACE specifications are computer-processable and can be unambiguously translated into a first-order logic language. The current version of ACE deals only with singular phenomena. We discuss how ACE can be extended with plurality. The extension proves to be difficult in th...

It is shown how thinking in terms of the protocol used can help clarify problems related to anthropic reasoning, such as the Doomsday Argument and the Sleeping Beauty Problem. There is a complex of problems related to anthropic reasoning, the Doomsday Argument [Leslie 1996] and the Sleeping Beauty Problem [Elga 2000] perhaps chief among them, that have generated a great deal of heat in the phil...

OBJECTIVE Angiotensin II (AII) and aldosterone are not always fully suppressed during chronic angiotensin converting enzyme (ACE) inhibitor treatment. In congestive heart failure (CHF) such failure of hormonal suppression is associated with increased mortality. This study examined how common AII and aldosterone increases are observed during routine clinical practice. PATIENTS AND METHODS 91 p...

BACKGROUND The angiotensin-I converting enzyme (ACE) plays a central role in the renin-angiotensin system, acting by converting the hormone angiotensin-I to the active peptide angiotensin-II (Ang-II). More recently, ACE was shown to act as a receptor for Ang-II, and its expression level was demonstrated to be higher in melanoma cells compared to their normal counterparts. However, the function ...
