Background: Angiotensin converting enzyme (ACE) upregulation in stromal cells of joints affected by rheumatoid arthritis may lead to higher tissue angiotensin II that is a vasoconstrictor and mitogen factor. To date, the role of angiotensin II on regulating blood flow in inflamed joints has not been studied. Methods: Acute and chronic joint inflammation was induced in rabbits by intra-articular...

Previous studies have shown that induction of 2kidney -1clip Goldblatt hypertension (2K-1C) induction in rats eliminates hypertensive response after inactivating of the central nucleus of the amygdale (ACe). The present study investigated the possibility of alteration in local renin angiotensin system (RAS) activity in ACe after hypertension induction. Clamps were placed on the left renal arter...

We describe the architecture of a novel ontology and rule editor ACE View. The goal of ACE View is to simplify viewing and editing expressive and syntactically complex OWL/SWRL knowledge bases by making most of the interaction with the knowledge base happen via Attempto Controlled English (ACE). This makes ACE View radically different from current OWL/SWRL editors which are based on formal logi...

Changes in arterial stiffness and structure occur during cardiovascular diseases and can be modified by angiotensin-converting enzyme (ACE) inhibitors. In the present study we investigated the role of membrane-bound ACE (t-ACE) in the regulation of arterial structure and mechanics. Large and small arteries of t-ACE-/- mice were isolated to determine the passive pressure-diameter relationship. W...

GABAergic inputs have been demonstrated in the central nucleus of the amygdala (ACe). However, the contribution of these inhibitory inputs to the cardiovascular responses elicited from the ACe is not known. Experiments were done in chloralose-anesthetized, paralyzed, and artificially ventilated male Wistar rats to investigate the effects of microinjections of GABA, the selective GABAA-receptor ...

We examined the topology of angiotensin-converting enzyme (ACE) mRNA expression, activity, and shedding in myocardial infarction-induced heart failure and sought to elucidate the source of the increased plasma ACE activity in this model. Three months after coronary ligature, lung, scar, and remaining viable left ventricular tissues were analyzed for ACE mRNA expression as well as tissue and sol...

Measurement of serum angiotensin-converting enzyme (ACE) activity can be helpful in the diagnosis and disease monitoring of sarcoidosis. Elevated serum ACE activity is found in 60-70% of sarcoidosis patients. Usually, the ACE activity is mildly increased (<3-fold the upper limit of the reference range) in sarcoidosis patients. Extremely elevated ACE activity is suggestive of the benign conditio...

Attempto Controlled English (ACE) is a knowledge representation language with an English syntax. Thus ACE can be used by anyone, even without being familiar with formal notations. The Attempto Parsing Engine translates ACE texts into discourse representation structures, a variant of first-order logic. Hence, ACE turns out to be a logic language equivalent to full first-order logic. The two view...

BACKGROUND Angiotensin-converting enzyme (ACE; Kininase II; CD143) hydrolyzes small peptides such as angiotensin I, bradykinin, substance P, LH-RH and several others and thus plays a key role in blood pressure regulation and vascular remodeling. Complete absence of ACE in humans leads to renal tubular dysgenesis (RTD), a severe disorder of renal tubule development characterized by persistent fe...
