EPR imaging by using an acyl-protected hydroxylamine, 1-acetoxy-3-carbamoyl-2,2,5,5-tetramethylpyrrolidine (ACP), in the head of a living rat after kainic acid (KA)-induced epileptic seizures was performed. ACP is a stable non-radical compound, but is easily deprotected with intracellular esterase
The concentration of adenosine triphosphate in the brain decreased before the onset of generalized convulsions in unanesthetized rats subjected to acute hypoxia or treated with hydroxylamine or pentylenetetrazole (Metrazol). As the convulsive episode continued, adenosine triphosphate decreased
The aim of the present study was to investigate the possible role of hydrogen sulfide (H(2)S) in the pathogenesis of recurrent febrile seizures (FS) in rats. On a rat model of recurrent FS, the ultrastructure of hippocampal neurons, the plasma level of H(2)S, the expressions of cystathionine
(Arylalkyl)azoles are a class of antiepileptic compounds including nafimidone, denzimol, and loreclezole (LRZ). Nafimidone and denzimol are thought to inhibit voltage-gated sodium channels (VGSCs) and enhance γ-aminobutyric acid (GABA)-mediated response. LRZ, a positive allosteric modulator of
1. The purpose of the present study was to investigate the interaction between hydrogen sulfide (H(2)S) and carbon monoxide (CO) during recurrent febrile seizures (FS) 2.H(2)S and CO are important intra- and intercellular messengers, regulating various brain functions. Our recent studies showed that
Nitroxides are stable free radical compounds that protect against the toxicity of reactive oxygen species in vitro and in vivo. Tempol (Aldrich, Milwaukee, WI, USA) is a cell-permeable hydrophilic nitroxide and has been shown to be an in vitro and in vivo radioprotector. The limitations of Tempol as
Hydrogen sulfide (H2S) is recognized as a new neuromodulator in regulating various brain functions. Some of our recent studies showed that H2S alleviates the hippocampal damage induced by recurrent febrile seizures (FS). In the present study, we used a rat model of recurrent FS and found that sodium
Starting from the corresponding acetophenone and glycine derivatives, a series of new 3-aminopyrroles was synthesized in few steps. Using this procedure with hydrazine and hydroxylamine instead of the glycinates provides access to 3-aminopyrazoles and 5-amino 1,2-oxazoles. The various derivatives
d-Tubocurarine (dtc) administered intracerebroventricularly (icv) to rats produced seizures. Gamma-aminobutyric acid (GABA) administered icv or hydroxylamine administered intraperitoneally (ip) protected the rats from dtc-induced seizures. GABA administered (ip) was ineffective. Local application of
Nitric oxide (NO) has been discovered recently to be a ubiquitous, endogenous mediator, which is responsible for a variety of normal physiological functions. However, NO also has been implicated in several pathophysiological processes. For example, the pulmonary toxicity of various nitrogen oxides,
The striatal neurochemical changes induced by pp'DDT (600 mg/kg) in mice were: an increase in the concentration of free ammonia, a decrease in the level of GABA and a reduction in the level of acetylcholine. These changes were maximal 5 h after treatment with pp'DDT, when the animals developed
This article aims to provide a research update on nitroxide radical compounds for application of anti-oxidative stress therapy. Nitroxide compounds such as 2,2,6,6-tetramethylpyperidine-1-oxyl (TEMPO) can catalytically react with reactive oxygen species (ROS) and are anticipated as new anti-oxidant
OBJECTIVE
To establish a specific procedure for the high-risk screening and diagnosis of organic acidurias and other inherited metabolic diseases in China.
METHODS
A nation-wide network for the high-risk screening and diagnosis of genetic metabolic diseases was formed to facilitate the
The anticonvulsive activity of seven newly-synthesized derivatives of barbituric acid, having a hydroxylamins groups substituted in second position, with respect to convulsive agents related with the GABA-ergic transmitter system: picrotoxin, bicuculline, thiosemicarbazide and 3-mercaptopropionic
