Identifying soil landscape units at a district scale is important as it allows for sustainable land-use management. However, given the large number of soil properties that need to be understood and mapped, cost-effective methods are required. In this study, we used a digital soil mapping (DSM) approach where remote and proximal sensed ancillary data collected across a farming district near Bour...

in order to investigate the effects of saline waters on some soil characteristics, this experiment was conducted with three irrigation water salinity treatments contains 1.7-3.4, 8-9 and 11-12.5 dsm-1 (low, medium and high salinity) and two irrigation water managements with four replications in a wheat-fallow-sugar beet-safflower rotation. results show that in (1) irrigation management with low...

OBJECTIVE This study evaluated the potential impact of proposed DSM-5 diagnostic criteria for autism spectrum disorder (ASD). METHOD The study focused on a sample of 933 participants evaluated during the DSM-IV field trial; 657 carried a clinical diagnosis of an ASD, and 276 were diagnosed with a non-autistic disorder. Sensitivity and specificity for proposed DSM-5 diagnostic criteria were ev...

Endothelin-1 (ET-1) is secreted from endothelial and vascular smooth muscle cells (VSMC) after intracellular hydrolysis of big ET-1 by endothelin converting enzyme (ECE). The metallopeptidase called ECE-1 is widely thought to be the physiological ECE, but unequivocal evidence of this role has yet to be provided. Endothelial cells express four isoforms of ECE-1 (ECE-1a, ECE-1b, ECE-1c, and ECE-1...

Endothelin-converting enzyme-1 and -2 (ECE-1 and -2) are membrane-bound metalloproteases that can cleave biologically the inactive endothelin-1 (ET-1) precursor to form active ET-1 in vitro. We previously reported developmental defects in specific subsets of neural crest-derived tissues, including branchial arch-derived craniofacial structures, aortic arch arteries, and the cardiac outflow trac...

We have previously reported the intracellular localization of the endothelin-converting enzyme-1 (ECE-1) in human umbilical vein endothelial cells. In the present study, we provide the first immunocytochemical and biochemical evidence for the presence of ECE-2 in human cells. ECE activity was determined by conversion of exogenously added big endothelin-1 (big ET-1) to ET-1 in subcellular fracti...

Endothelin-converting enzyme-1 (ECE-1) is a membrane-bound metalloprotease that catalyses the conversion of inactive big endothelins into active endothelins. Here we have examined whether the three isoforms of human ECE-1 (ECE-1a, ECE-1b and ECE-1c) are modified by the covalent attachment of the fatty acid palmitate and have evaluated a potential functional role of this modification. To do this...

Endothelin-converting enzyme-1 (ECE-1) is a membrane-bound metalloprotease that cleaves biologically inactive big endothelin-1 (ET-1) into active ET-1. ET-1 is involved in the cardiovascular homeostasis and the development of cardiovascular diseases including pulmonary arterial hypertension and heart failure. Atrial natriuretic peptide (ANP) is an endogenous hormone that is released from the...
