13. Caracterização patológica e parasitológica de Prosthenorchis elegans em Callithrix geoffroyi primate de vida livre da Mata Atlântica
RESUMO: Prosthenorchis elegans é um acantocéfalo intestinal descrito em primatas neotropicais. Apesar do parasitismo por P. elegans já ter sido descrito de saguis da Mata Atlântica brasileira, não há relatos da infecção em saguis-da-cara-branca (Callithrix geofroyi) de vida livre. O objetivo deste estudo é relatar um caso de parasitismo por P. elega

15. Choledocystus elegans (Digenea: Plagiorchiidae) de Leptodactylus paraensis (Amphibia: Leptodactylidae) da Amazônia brasileira
Resumo Os trematodas são parasitas de vários grupos de vertebrados incluindo os anfíbios, contudo o que se conhece sobre a taxonomia destes parasitas ainda é confusa. O trematoda Choledocystus elegans foi encontrado no intestino delgado de Leptodactylus paraensis na Amazônia oriental e apresenta as seguintes características: vários espinhos pontiagudo

16. Selenocysteine modulates resistance to environmental stress and confers anti-aging effects in C. elegans
OBJECTIVE: The free radical theory of aging suggests that cellular oxidative damage caused by free radicals is a leading cause of aging. In the present study, we examined the effects of a well-known anti-oxidant amino acid derivative, selenocysteine, in response to environmental stress and aging using Caenorhabditis elegans as a model system. METHOD: The r

17. Biotransformation of bromhexine by Cunninghamella elegans, C. echinulata and C. blakesleeana
Abstract Fungi is a well-known model used to study drug metabolism and its production in in vitro condition. We aim to screen the most efficient strain of Cunninghamella sp. among C. elegans, C. echinulata and C. blakesleeana for bromhexine metabolites production. We characterized the metabolites produced using various analytical tools and compared them with

20. Rosmarinus officinalis L. increases Caenorhabditis elegans stress resistance and longevity in a DAF-16, HSF-1 and SKN-1-dependent manner
Improving overall health and quality of life, preventing diseases and increasing life expectancy are key concerns in the field of public health. The search for antioxidants that can inhibit oxidative damage in cells has received a lot of attention. Rosmarinus officinalis L. represents an exceptionally rich source of bioactive compounds with pharmacological p

21. Artemisia annua increases resistance to heat and oxidative stresses, but has no effect on lifespan in Caenorhabditis elegans
Abstract It is suggested that oxidative stress induced by cellular reactive oxygen species is one of the major causal factors of aging. The effect of dietary supplementation of anti-oxidants on response to environmental stressors and lifespan has been studied in various model organisms. In the present study, we examine the effect of Artemisia annua extract o

22. Coupling DLLME-CE for the Stereoselective Analysis of Venlafaxine and Its Main Metabolites after Biotransformation by Fungi
Fungal biotransformations have become very important in the study of chiral drugs because the reactions performed by these microorganisms may be enantioselective. However, analyses of analytes present in liquid culture medium have proved to be very difficult due to the complexity of this matrix. The aim of this work was to couple dispersive liquid-liquid mic

23. Corynebacterium diphtheriae putative tellurite-resistance protein (CDCE8392_0813) contributes to the intracellular survival in human epithelial cells and lethality of Caenorhabditis elegans
Corynebacterium diphtheriae, the aetiologic agent of diphtheria, also represents a global medical challenge because of the existence of invasive strains as causative agents of systemic infections. Although tellurite (TeO32-) is toxic to most microorganisms, TeO32--resistant bacteria, including C. diphtheriae, exist in nature. The presence of TeO32--resistanc

24. Lifespan extension and increased resistance to environmental stressors by N-Acetyl-L-Cysteine in Caenorhabditis elegans
OBJECTIVE: This study was performed to determine the effect of N-acetyl-L-cysteine, a modified sulfur-containing amino acid that acts as a strong cellular antioxidant, on the response to environmental stressors and on aging in C. elegans. METHOD: The survival of worms under oxidative stress conditions induced by paraquat was evaluated with and without in vi
