1. Efficacy of phosphocreatine pre-administration on XIAP and Smac in ischemic penumbra of rats with focal cerebral ischemia reperfusion injury
Abstract Purpose: To observe the efficacy of phosphocreatine pre-administration (PCr-PA) on X-linked inhibitor of apoptosis protein (XIAP), the second mitochondia-derived activator of caspase (Smac) and apoptosis in the ischemic penumbra of rats with focal cerebral ischemia-reperfusion injury (CIRI). Methods: A total of 60 healthy male Sprague Dawley (SD)

2. Thalamic metabolic abnormalities in patients with Huntington's disease measured by magnetic resonance spectroscopy
Huntington's disease (HD) is a neurologic disorder that is not completely understood; its fundamental physiological mechanisms and chemical effects remain somewhat unclear. Among these uncertainties, we can highlight information about the concentrations of brain metabolites, which have been widely discussed. Concentration differences in affected, compared to

6. CREATINE INCREASES Na+,K+-ATPase ACTIVITY AND PREVENTS SEIZURES INDUCED BY PENTYLENETETRAZOLE IN RATS / CREATINA AUMENTA A ATIVIDADE DA Na+,K+-ATPase E PREVINE O APARECIMENTO DAS CONVULSÕES INDUZIDAS POR PENTILENOTETRAZOL EM RATOS
Creatine, an endogenous guanidino compound produced on liver, kidneys, pancreas, testes and brain, has been aim of several studies over the last years. Although most studies attribute the effects of creatine to their energetic buffer role, recent findings have suggested actions non-related to energy metabolism. Researches have shown that this compound may ac

7. Espectroscopia por ressonância magnética de prótons em epilepsia mioclônica juvenil sugere o comprometimento de uma rede neuronal específica
OBJECTIVES: The neuroanatomical basis and the neurochemical abnormalities that underlay juvenile myoclonic epilepsy (JME) are not fully defined. While the thalamus plays a central role in synchronization of widespread regions of the cerebral cortex during a seizure, emerging evidence suggests that all cortical neurons may not be homogeneously involved.

9. EFEITO DA ADMINISTRAÇÃO AGUDA DE CREATINA SOBRE A MEMÓRIA EM RATOS / EFFECT OF THE SYSTEMIC INJECTION OF CREATINE ON THE MEMORY OF RATS
Glucose is the most important energy substrate for the central nervous system. Besides its energetic function, glucose facilitates memory in experimental animals, an effect that has been related to its energy functions. Other important cerebral energy substrate is creatine, which is endogenously synthesized and converted to phosphocreatine, an immediate and

12. Serum aldolase and phosphocreatine kinase in umbilical cord blood
Aldolase was estimated in the cord blood of 81 newborn infants and phosphocreatine kinase in 87 infants. There is a wide range in the results, with some values falling in the range reported in children with muscular dystrophy or of carriers of the disease. There is no correlation of the serum enzyme levels with the infant's birth weight. High levels of phosp
