Effects of GABA(A) receptor blockade on regional cerebral blood flow and blood-brain barrier disruption in focal cerebral ischemia.

Oak Z Chi et al.

Journal of the neurological sciences, 301(1-2), 66-70 (2010-11-26)

In cerebral ischemia, transmission by the inhibitory neurotransmitter, γ-aminobutyric acid (GABA) is altered. This study was performed to determine whether blockade of GABA(A) receptor would affect regional cerebral blood flow (rCBF) and blood-brain barrier (BBB) permeability in a focal ischemic

Conformations of helical Aib peptides containing a pair of L-amino acid and D-amino acid.

Yosuke Demizu et al.

Journal of peptide science : an official publication of the European Peptide Society, 18(7), 466-475 (2012-05-24)

A pair of L-leucine (L-Leu) and D-leucine (D-Leu) was incorporated into a-aminoisobutyric acid (Aib) peptide segments. Thedominant conformations of four hexapeptides, Boc-L-Leu-Aib-Aib-Aib-Aib-L-Leu-OMe (1a), Boc-D-Leu-Aib-Aib-Aib-Aib-L-Leu-OMe(1b), Boc-Aib-Aib-L-Leu-L-Leu-Aib-Aib-OMe (2a), and Boc-Aib-Aib-D-Leu-L-Leu-Aib-Aib-OMe (2b), were investigated by IR,¹H NMR, CD spectra, and X-ray crystallographic analysis.

The effects of isoflurane pretreatment on cerebral blood flow, capillary permeability, and oxygen consumption in focal cerebral ischemia in rats.

Oak Z Chi et al.

Anesthesia and analgesia, 110(5), 1412-1418 (2010-03-23)

We performed experiments to test whether isoflurane pretreatment produces vascular effects, especially at the levels of arterioles and capillaries affecting regional cerebral blood flow (rCBF), O(2) supply and consumption, or capillary permeability in focal cerebral ischemia. Because inducible nitric oxide

Methyl jasmonate-induced defense responses are associated with elevation of 1-aminocyclopropane-1-carboxylate oxidase in Lycopersicon esculentum fruit.

Mengmeng Yu et al.

Journal of plant physiology, 168(15), 1820-1827 (2011-07-27)

It has been known that methyl jasmonate (MeJA) interacts with ethylene to elicit resistance. In green mature tomato fruits (Lycopersicon esculentum cv. Lichun), 0.02mM MeJA increased the activity of 1-aminocyclopropane-1-carboxylate oxidase (ACO), and consequently influenced the last step of ethylene

In silico interpretation of cw-ESR at 9 and 95 GHz of mono- and bis- TOAC-labeled Aib-homopeptides in fluid and frozen acetonitrile.

Silvia Carlotto et al.

The journal of physical chemistry. B, 115(44), 13026-13036 (2011-10-06)

In this paper, we address the interpretation of molecular properties of selected singly and doubly spin-labeled peptides from continuous-wave electron spin resonance (cw-ESR) spectroscopy. This study is performed by means of an integrated computational approach that merges a stochastic treatment
