Hydrogen sulfide is an endogenous gasotransmitter and its mechanism of action involves activation of ATP-sensitive K(+) channels and phosphodiesterase inhibition. As both mechanisms are potentially involved in malignant hyperthermia (MH), in the present study we addressed the involvement of the
OBJECTIVE
To study the alteration of hydrogen sulfide (H(2)S)/ cystathionine-beta-synthase (CBS) system during recurrent febrile seizures (FS) in the hippocampus of developing rats.
METHODS
The rats were randomly divided into control group (n=8) and hyperthermia-treated group (n=22). Which was
BACKGROUND AND PURPOSE
Human malignant hyperthermia (MH) syndrome is induced by volatile anaesthetics and involves increased levels of
cystathionine β-synthase (CBS)-derived H
2 S within skeletal muscle. This increase contributes to skeletal muscle hypercontractility.
AIM
Whereas some patients have important changes in body core temperature (Tb) during systemic inflammation, others maintain a normal Tb, which is intrinsically associated to immune paralysis. One classical model to study immune paralysis is the use of repeated administration of
Homocystinuria presenting as cerebral venous thrombosis is not usual. We report on a 13-year-old boy who was admitted to the hospital due to severe headache, nausea, vomiting and fever (38 degrees C). The patient was Marfan like and presented left hemiparesis and meningeal irritation sings. He was
We tested the hypothesis that the neuromodulator hydrogen sulfide (H2S) in the preoptic area (POA) of the hypothalamus modulates the febrigenic signaling differently in sedentary and trained rats. Besides H2S production rate and protein expressions of H2S-related synthases cystathionine β-synthase
The presence of the H2 S pathway in skeletal muscle (SKM) has recently been established. SKM expresses the three constitutive H2 S-generating enzymes in animals and humans, and it actively produces H2 S. The main, recognized molecular targets of H2 S, that is, potassium channels and PDEs, have been
Hydrogen sulfide (H(2)S) is a gaseous neuromodulator endogenously produced in the brain by the enzyme cystathionine β-synthase (CBS). We tested the hypothesis that H(2)S acts within the anteroventral preoptic region of the hypothalamus (AVPO) modulating the production of prostaglandin (PG) E(2) (the
Thermoregulatory responses to lipopolysaccharide (LPS) are affected by modulators that increase (propyretic) or decrease (cryogenic) body temperature (Tb). We tested the hypothesis that central hydrogen sulfide (H2S) acts as a thermoregulatory modulator and that H2S production in the anteroventral
