In the title dinuclear complex, [Yb(2)(C(8)H(7)O(3))(6)(C(10)H(8)N(2))(2)(H(2)O)(2)]·H(2)O, the Yb(III) atoms are coordinated by eight O atoms from four 2-(4-hy-droxy-phen-yl)acetate (HPAA) ligands and a water mol-ecule, and one N atom from a 4,4'-bipyridine (bipy) ligand in a distorted tricapped trigonal-prismatic geometry. Whereas four HPAA ligands coordinate to just two Yb(III) atoms, the re...

Ibuprofen, a non-selective inhibitor of cyclooxygenase, is one the most used non-steroidal anti- inflammatory drugs (NSAID) and pain relievers. Its effect on developing fetal neuroendocrine system when taken by pregnant mother does not well established. The aim this study was to evaluate long-term consequences administration ibuprofen rats with regard hormonal profile sexual differentiation bra...

Recent studies have shown that reduced fetal growth is associated with the development of the insulin resistance syndrome in adult life. The mechanisms are not known. However increased activity of the hypothalamic-pituitary-adrenal axis (HPAA) may underlie this association; the axis is known to be reset by fetal growth retardation in animals, and there is evidence in humans of an association be...

BACKGROUND Young adults born preterm at very low birth weight (VLBW, ≤1500 g) have higher levels of cardiovascular risk factors, including impaired glucose regulation, than their term-born peers. This could be mediated through altered hypothalamic-pituitary-adrenal axis (HPAA) response to stress. OBJECTIVE To compare HPAA, glucose and insulin responses provoked by psychosocial stress in VLBW ...

BACKGROUND The hypothalamus is an essential part of the brain that responds to a variety of signaling including stressful stimulations and acupuncture signals. It is also the key element of the hypothalamic-pituitary-adrenal cortex axis(HPAA). The effect of acupuncture is transmitted into the brain from the distance sensory receptor around the acupoints via peripheral nerves and body fluid. In ...

The enzyme NCS [(S)-norcoclaurine synthase; EC 4.2.1.78] found in the common meadow rue, Thalictrum flavum, and other plant species, is involved in the biosynthesis of BIAs (benzylisoquinoline alkaloids). This group of plant secondary metabolites comprises pharmacologically-active compounds such as morphine and codeine. NCS catalyses the condensation of 4-HPAA (4-hydroxyphenylacetaldehyde) and ...

A simple and mild procedure for the conversion of anilines into aryl isocyanates is described using the 3-hydroxypropylammonium acetate (HPAA) ionic liquid as a novel and efficient media has been explored in the synthesis of aryl isocyanates from the reaction of substituted urea with sodium nitrite in a water immiscible solvent. This ionic liquid can be easily recovered and reused for many time...
