13. Espectroscopia de fósforo por ressonância magnética em malformações do desenvolvimento cortical
IntroductionMalformations of cortical development (MCD) result from disruptions in the dynamic process of cerebral corticogenesis and are important causes of epilepsy, motor deficits and cognitive impairment.ObjectivesThe aim of this study was to evaluate phospholipids metabolism in vivo in a series of patients with epilepsy and MCD.MethodsThirty-seven patie

14. P2X7 receptor mediates activation of microglial cells in prostate of chemically irritated rats
Purpose Evidence shows that adenosine triphosphate (ATP) is involved in the transmission of multiple chronic pain via P2X7 receptor. This study was to investigate the P2X7 and microglial cells in the chronic prostatitis pain. Materials and Methods Rats were divided into control group and chronic prostatitis group (n = 24 per group). A chronic prostatitis

15. Ação do inibidor da enzima dipeptidil peptidase 4 sobre o pré-condicionamento isquêmico em pacientes portadores de diabetes mellitus tipo 2 e doença arterial coronariana estável / Effect of dipeptidyl peptidase-4 enzyme inhibitor on ischemic preconditioning in patients with type 2 diabetes and symptomatic coronary artery disease
Ischemic preconditioning (IPC) refers to the phenomenon in which short periods of myocardial ischemia and reperfusion promote resistance to a subsequent prolonged ischemic insult. Some hypoglycemic drugs, such as glibenclamide and repaglinide, are able to inhibit this protective phenomenon probably by its effects as blockers of adenosine triphosphate-depende

16. Modelo de regulação dos nucleotídeos extracelulares no líquido superficial das vias respiratórias
Extracellular nucleotides play a key role in the regulation of mucociliary clearance and thus are essential in protecting the airways against inhaled pathogens. Adenosine triphosphate (ATP), adenosine diphosphate (ADP) and adenosine monophosphate (AMP) nucleotides are secreted by the respiratory epithelium to the airway surface liquid, where they are metabol

17. Avaliação do modelo de hiperargininemia sobre parâmetros neuroquímicos, moleculares e compartamentais em peixe-zebra (Danio rerio): uma abordagem sobre o sistema purinérgico
Hyperargininemia is a rare disease caused by an innate error of the metabolism (EIM) biochemically characterized by the accumulation of arginine in body tissues due to arginase deficits. Mental retardation and other neurological symptoms are common in hyperargininemic patients. Several mechanisms have been proposed to describe the neurotoxicity of hiperargin

18. ATIVIDADE DE ECTOENZIMAS E DE COLINESTERASES E BIOMARCADORES DE ESTRESSE OXIDATIVO EM PACIENTES COM CÂNCER DE PULMÃO / ACTIVITY OF ECTOENZIMAS AND CHOLINESTERASES AND OXIDATIVE STRESS BIOMARKERS IN PATIENTS WITH LUNG CANCER
Lung cancer has become one of the most commonly diagnosed neoplastic diseases, as well as one of the most lethal worldwide, characterized, therefore, as a public health problem. This spread of lung cancer in the world population, which is clearly seen in statistics, is closely related to smoking, and smoking is considered one of the main risk factors that le

19. Chi-square analysis of the reduction of ATP levels in L-02 hepatocytes by hexavalent chromium
This study explored the reduction of adenosine triphosphate (ATP) levels in L-02 hepatocytes by hexavalent chromium (Cr(VI)) using chi-square analysis. Cells were treated with 2, 4, 8, 16, or 32 μM Cr(VI) for 12, 24, or 36 h. Methyl thiazolyl tetrazolium (MTT) experiments and measurements of intracellular ATP levels were performed by spectrophotometry or bi

20. Analysis of the NTPDase and ecto-5'-nucleotidase profiles in serum-limited Trichomonas vaginalis
Trichomonas vaginalis is a parasite of the human urogenital tract that causes trichomonosis, the most prevalent non-viral sexually transmitted disease. Ectonucleoside triphosphate diphosphohydrolase (NTPDase) family members, which hydrolyse extracellular ATP and ADP and ecto-5′-nucleotidase, which hydrolyses AMP, have been characterised in T. vaginalis.

21. Participação do sistema purinérgico no locus coeruleus (LC) no controle cardiorrespiratório e térmico em normocapnia e hipercapnia em ratos não anestesiados
O LC é considerado uma região quimiossensível a CO2/pH em mamíferos e anfíbios, especificamente os neurônios noradrenérgicos. A neuromodulação purinérgica no LC desperta um interesse particular uma vez que a adenosina 5-trifosfato (ATP) atua como neuromodulador em várias áreas do tronco encefálico envolvidas na regulação cardiorrespiratória,

22. Gadolinium increases the vascular reactivity of rat aortic rings
Gadolinium (Gd) blocks intra- and extracellular ATP hydrolysis. We determined whether Gd affects vascular reactivity to contractile responses to phenylephrine (PHE) by blocking aortic ectonucleoside triphosphate diphosphohydrolase (E-NTPDase). Wistar rats of both sexes (260-300 g, 23 females, 7 males) were used. Experiments were performed before and after in

24. A intrigante bioquímica da niacina: uma revisão crítica
Niacin (nicotinamide, nicotinic acid) interferes on homeostasis, DNA regulation, signaling and longevity. Nicotinic acid reduces synthesis of lipoproteins-apo-B and increases HDL. Its antilipemic action in liver produces: 1) inhibition of DGAT2, with decreased triacylglycerol synthesis, 2) downregulation of the b-chain of adenosine triphosphate synthase, lea
