Abstract Activities of X-prolyl dipeptidyl-aminopeptidase (EC 3.4.14.1) and amine oxidase (EC 1.4.3.6) in serum were assayed in two groups of patients, children two to nine years old and adults 23 to 60 years old, with hypertrophic scars after severe burn. The peptidase activity tended to be low initially for several months after the burn, but then returned to normal after six months. These changes were marked in the child group, less so in the adult group. Similar but less-pronounced changes were also observed in serum amino oxidase activity. The two serum enzyme activities showed a significant positive correlation (r = 0.668, p less than 0.001, n = 27) in the patients.

The aggressive display in Betta splendens is particularly prominent, and vital to its adaptation to the environment. Methylmercury is an organic variation of Hg that presents particularly pronounced neuro-behavioral effects. The present experiments aim to test the effect of acute and chronic poisoning with methylmercury on the display in Bettas. The animals were poisoned by trophic means in both experiments (16 ug/kg in acute poisoning; 16 ug/kg/day for chronic poisoning), and tested in agonistic pairs. The total frequency of the display was recorded, analyzing the topography of the agonistic response. The methylmercury seems to present a dose- and detoxification-dependent effect on these responses, with a more pronounced effect on motivity in acute poisoning and on emotionality in the chronic poisoning. It is possible that this effect could be mediated by alteration in the mono-amino-oxidase systems.

Aldehydes are a class of carbonyl compounds widely used as intermediates in the pharmaceutical, cosmetic and food industries. To date, there are few fully enzymatic methods for synthesizing these highly reactive chemicals. In the present work, we explore the biocatalytic potential of an amino oxidase extracted from the etiolated shoots of Lathyrus cicera for the synthesis of value-added aldehydes, starting from the corresponding primary amines. In this frame, we have developed a completely chromatography-free purification protocol based on crossflow ultrafiltration, which makes the production of this enzyme easily scalable. Furthermore, we determined the kinetic parameters of the amine oxidase toward 20 differently substituted aliphatic and aromatic primary amines, and we developed a biocatalytic process for their conversion into the corresponding aldehydes. The reaction occurs in aqueous media at neutral pH in the presence of catalase, which removes the hydrogen peroxide produced during the reaction itself, contributing to the recycling of oxygen. A high conversion (>95%) was achieved within 3 h for all the tested compounds.

Distimia é um transtorno depressivo de natureza crônica, mas de menor gravidade que a depressão maior, cujos sintomas persistem por mais ou menos dois anos. Este artigo aborda aspectos relativos à eficácia do tratamento farmacológico na distimia, a partir de resultados de revisões sistemáticas recentemente concluídas. Em termos de eficácia, os resultados foram similares para as diferentes classes de drogas, tais como tricíclicos (ADT), inibidores seletivos da recaptação da serotonina (ISRS), inibidores da mono-amino-oxidase (IMAO) e outras drogas (sulpirida, amineptina, e ritanserina). Os pacientes tomando tricíclicos relataram um maior número de efeitos adversos, comparado com placebo. Em resumo, o tratamento farmacológico da distimia é eficaz, sem efeito diferencial entre os diversos antidepressivos. O uso de tricíclicos está associado à maior ocorrência de efeitos adversos e de desistências. Apesar de a distimia ser uma doença crônica, existe ainda informação limitada sobre a qualidade de vida dos pacientes e sobre o tratamento a médio e longo prazo.
