1. Effect of monoamine oxidase B A644G variant on nicotine dependence and/or schizophrenia risk
Abstract Objectives Schizophrenia (Sch) is a severe and chronic mental illness. Smoking prevalence is higher in patients with Sch than general population. We aimed to investigate the effects of MAOB gene A644G variant on nicotine dependence (ND) and Sch+ND risk in Turkish population and to evaluate by bioinformatic analysis. Methods Present study include

2. Combined structure- and ligand-based virtual screening to evaluate caulerpin analogs with potential inhibitory activity against monoamine oxidase B
Abstract Natural marine products can help increase the quality of life in patients with neurological diseases. A large number of marine products act against Alzheimer's disease through varying pathways. According to structure- and ligand-based analyses, caulerpin, an alkaloid primarily isolated from the genus Caulerpa, possesses activity against monoamine ox

3. Evaluation of the neurotoxic effects of ayahuasca tea / Avaliação dos efeitos neurotóxicos do chá ayahuasca
Ayahuasca tea is a psychotropic beverage that has caused controversy due to the fact of being used indiscriminately by some group of people and the ease of purchase in the worldweb. The tea is derived by boiling the bark of the liana Banisteriopsis Caapi (B. Caapi) together with the leaves of Psychotria Viridis (P.Viridis). B. Caapi contains alkaloids as har

4. Correlation between total nitrite/nitrate concentrations and monoamine oxidase (types A and B) and semicarbazide-sensitive amine oxidase enzymatic activities in human mesenteric arteries from non-diabetic and type 2 diabetic patients
The aim of this study was to determine the correlation between total nitrite/nitrate concentrations (NOx) and the kinetic parameters of monoamine oxidase enzymes (MAO-A and MAO-B) and semicarbazide-sensitive amine oxidase (SSAO) in human mesenteric arteries. Arteries were from non-diabetic and type 2 diabetic patients with sigmoid or rectum carcinoma for who

5. PERFIL FARMACOLÓGICO DO TIPO ANTIDEPRESSIVO DO COMPOSTO 3-(4-FLUOROFENILSELENIL)-2,5 DIFENILSELENOFENO: ENVOLVIMENTO DO SISTEMA SEROTONINÉRGICO / ANTIDEPRESSANT-LIKE PHARMACOLOGICAL PROFILE OF 3-(4- FLUOROPHENYLSELENYL)-2,5-DIPHENYLSELENOPHENE: INVOLVEMENT OF SEROTONERGIC SYSTEM
Depression is a serious, recurrent and incapacitating psychiatric condition with a heavy social burden. The pharmacological approach to this disorder employs therapy with antidepressant drugs, which have side effects and numerous limitations. In view of the promising pharmacological properties of containing-selenium molecules, this study evaluated the effect

6. AVALIAÇÃO DO ENVOLVIMENTO DA ENZIMA MONOAMINA OXIDASE B EM MODELOS DE DOR PÓS-OPERATÓRIA E NEUROPÁTICA EM CAMUNDONGOS / ASSESSMENT OF MONOAMINE OXIDASE B INVOLVEMENT ON MODELS OF POSTOPERATIVE AND NEUROPATHIC PAIN IN MICE
As monoaminas possuem uma função modulatória importante nas vias descendentes do controle da dor e estão envolvidas no mecanismo antinociceptivo de diversos fármacos comumente utilizados no tratamento de síndromes dolorosas. Nesse estudo, nós avaliamos a participação da monoamina oxidase B (MAO-B), uma enzima chave envolvida no metabolismo das monoa

7. EFEITO DE 2-ARIL(HETEROARIL)-4,5-DIIDRO-1H-IMIDAZÓIS SOBRE A ATIVIDADE DA ENZIMA MONOAMINA OXIDASE IN VITRO / EFFECT OF 2-ARYL-HETEROARYL-4,5-DIHYDRO-1H-IMIDAZOLES ON MONOAMINE OXIDASE ACTIVITY IN VITRO.
A monoamina oxidase (MAO) é uma enzima que contém o dinucleotídeo adenina-flavina (FAD) e que está presente na membrana externa da mitocôndria de células neuronais, glia e outras células. Seu papel inclui a regulação dos níveis de aminas biogênicas e xenobióticas no cérebro e em tecidos periféricos pela desaminação oxidativa. Com base na espe

8. Influências de um inibidor seletivo da monoamino-oxidase tipo-B (IMAO-B) na sensibilização comportamental para anfetamina em camundongos / Influences of a selective inhibitor monoamine oxidase type-B (IMAO-B) in behavior sensitization for amphetamine in mice.
A sensibilização comportamental é caracterizada por aumento no efeito comportamental de uma droga após administrações repetidas. Este fenômeno é intensamente aplicado em estudos com modelos animais que enfocam a dependência de drogas. A maioria destas drogas promove adaptações em sistemas de neurotransmissão, (ex. sistema dopaminérgico), como é

9. Distribution of membrane-bound monoamine oxidase in bacteria.
The distribution of membrane-bound monoamine oxidase in 30 strains of various bacteria was studied. Monoamine oxidase was determined by using an ammonia-selective electrode; analyses were sensitive and easy to perform. The enzyme was found in some strains of the family Enterobacteriaceae, such as Klebsiella, Enterobacter, Escherichia, Salmonella, Serratia, a

10. Pressor sensitivity to tyramine in patients with headache: relationship to platelet monoamine oxidase and to dietary provocation.
The pressor responses to oral and intravenous tyramine were not different from controls in migrainous patients with or without a history of attacks triggered by foods. However, patients who reported a dietary trigger were more likely to develop headache after tyramine administration than those without such a dietary history. Pressor responses to intravenous

12. cDNA cloning of human liver monoamine oxidase A and B: molecular basis of differences in enzymatic properties.
The monoamine oxidases play a vital role in the metabolism of biogenic amines in the central nervous system and in peripheral tissues. Using oligonucleotide probes derived from three sequenced peptide fragments, we have isolated cDNA clones that encode the A and B forms of monoamine oxidase and have determined the nucleotide sequences of these cDNAs.
