Angiotensin II acts on cultured rat aortic vascular smooth muscle cells to stimulate phospholipase C-mediated hydrolysis of membrane phosphoinositides and subsequent formation of diacylglycerol and inositol phosphates. In intact cells, angiotensin II induces a dose-dependent increase in diglyceride which is detectable after 5 s and sustained for at least 20 min. Angiotensin II (100 nM)-stimulat...

Nonlinear structural equation modeling provides many advantages over analyses based on manifest variables only. Several approaches for the analysis of latent interaction effects have been developed within the last 15 years, including the partial least squares product indicator approach (PLS-PI), the constrained product indicator approach using the LISREL software (LISREL-PI), and the distributi...

The molecular structures of two salicylaldehyde thiosemicarbazone derivatives, namely salicylaldehyde 4-phenylthiosemicarbazone, C(14)H(13)N(3)OS, (I), and 4-methoxysalicylaldehyde 4-phenylthiosemicarbazone, C(15)H(15)N(3)O(2)S, (II), both of potential pharmacological interest, are found in the keto (thione) tautomeric form. The first compound represents a second triclinic polymorph of composit...

A donor-acceptor compound based on N,N,N',N'-tetramethyl-p-phenylene-diamine and 1,2,4,5-tetracyanobenzene (TMPD:TCNB) has been synthesized. The crystal structure of the black 1:1 complex formed between TMPD and TCNB has been determined by single crystal X-ray diffraction at room temperature. The compound crystallizes in the triclinic space group P-1 with cell dimensions: a = 7.4986(15) å, b =7...

such ion-sink methods as feo coated strips, (pi), can adsorb and collect p from soil solution. ion sink methods function similar to plant-root surface, adsorbing available p ions from the p pool in the soil. the objective of this study was to compare pi test with olsen, ab-dtpa, bray 2 and mehlich 2 methods to estimate the availability of soil p in alfalfa (medicago sativa). available p was det...

Thyrotropin-releasing hormone (TRH) stimulated the rapid and specific hydrolysis of phosphatidylinosito1 (PI) and its conversion to 1,2-diacylglycerol and phosphatidic acid (PA) in GH3 cells, cloned rat pituitary cells that secrete prolactin. The TRH induced fall in the level of PI occurred by 15 s and resulted in a lower steady state level by 2 min (1.78 f 0.05 uersus 1.38 f 0.03 nmol of PI/1...

Results A cohort of 204 patients was studied. Age 51 +/9 years; 156 (76,5%) were male; Logistic Euroscore (LE) of 5.1 +/8.4, LVEF 58 +/11. Surgery was 86 (42.2%) CABG, 79 (38.7%) valvular, 16 (7.8%) combined surgery and 23 (11.3%) others. 28 (13.7%) were self-employed. 15 of them already had a PI at the time of surgery. Patients with PI presented a LE of 6.7+/3.9 Vs. 11+/5 (p = 0.006); age 53+/...

In the present study the structure of obsessive±compulsive phenomena in non-clinical adolescents was investigated by `The Padua Inventory' (PI). The PI is a self-report measure of obsessive and compulsive symptoms which is used in clinical and research settings. The use of PI in adolescents has been limited by the lack of normative data. Consequently, adolescent validation has both theoretical ...
