| Introducción: las plantas son una fuente de diversidad natural por la gran variedad de compuestos que sintetizan. Particularmente las antraquinonas resultan un importante grupo de metabolitos secundarios con actividad antimicrobiana y antioxidante. Objetivos: evaluar la actividad antimicrobiana del extracto diclorometánico de raíces de Morinda royoc L., así como su toxicidad contra Artemia salina. Métodos: la actividad antimicrobiana se determinó utilizando el método de microdilución en placa de 96 pozos. Se evaluó la actividad del extracto frente a 7 aislados clínicos de Candida spp. y frente a las bacterias Staphylococcus aureus resistente a meticilina, Staphylococcus aureus ATCC 12598, Enterococus faecales, Escherichia coli, Acinetobacter baumanii,... |

| Los géneros Piper y Lepianthes han sido empleados como fuente de insecticidas y en la medicina natural. Son conocidas las propiedades antifúngica, insecticida, antialimentaria, estimulante, bactericida y citotóxica de muchos de sus extractos. El objetivo de este trabajo fue establecer las potencialidades de tres aceites esenciales de especies de estos géneros como candidatos para el desarrollo de productos con actividad plaguicida y antitumoral. Los aceites esenciales de P. auritum (CA1), P. aduncum subsp. ossanum (PAO1) y L. umbellata (LU1) fueron obtenidos por hidrodestilación empleando un equipo Clevenger y se evaluaron frente a Artemia salina, organismo indicador de actividad plaguicida y antitumoral. La actividad antibacteriana de los aceites... |

| Abstract: This study evaluates the antibacterial, cytotoxic activities, and phytochemical composition, of Callistemon citrinus, Hibiscus rosa-sinensis and Plumbago auriculata leaves and flowers, three ornamental plants in Mexico. However, in other countries offers a range of other uses. Ethanol extracts of C. citrinus leaf and flower presented stronger antibacterial activity than the extracts obtained from the other two plants. C. citrinus leaf showed low cytotoxicity (LC50 <600 µg/mL) on the brine shrimp test, whereas the ethanol extracts of H. rosa-sinensis and P. auriculata leaves showed no cytotoxic activity. Flower extracts obtained from the three plants did no exhibit cytotoxicity. GC-MS analysis revealed that the ethanol extract of P. auriculata... |

| Ethanol extracts from six selected species from the Cerrado of the Central-Western region of Brazil, which are used in traditional medicine for the treatment of infectious diseases and other medical conditions, namely Erythroxylum suberosum St. Hil. (Erythroxylaceae), Hyptis crenata Pohl. ex Benth. (Lamiaceae), Roupala brasiliensis Klotz. (Proteaceae), Simarouba versicolor St. Hil. (Simaroubaceae), Guazuma ulmifolia Lam. (Sterculiaceae) and Protium heptaphyllum (Aubl.) March. (Burseraceae), as well as fractions resulting from partition of these crude extracts, were screened in vitro for their antifungal and antibacterial properties. The antimicrobial activities were assessed by the broth microdilution assay against six control fungal strains, Candida... |

| The dried cysts of the brine shrimp <i>Artemia salina</i> are used all over the world as a most convenient source of live crustacean nauplii which are indispensable for the larval stages of many fishes and crustaceans. With the expansion of mariculture, the demand for the resting eggs of <i>Artemia</i> has greatly increased and at certain moments of the year it exceeds the offer. Hence it is even more regrettable that in most mariculture farms a considerable wastage of this precious live food occurs: the nauplii are usually hatched in uncontrolled conditions, and the instar stage at which the <i>Artemia</i> larvae are offered to the predator is not considered and varies from one experiment to another. From fundamental... |

| Myrcia hatschbachii D. Legrand (Myrtaceae) is a native and endemic species from Brazil. This study investigated the essential oil composition, phytotoxic potential, in vitro toxicity, antioxidant properties and antibacterial activity of species. Chromatographic analysis of essential oil identified trans-calamanene, (E)-caryophyllene and spathulenol as major components. Antioxidant capacity was determined by the DPPH• scavenging method and phosphomolybdenum complex formation assay. Antibacterial activity was evaluated using the Minimal Inhibitory Concentration test, demonstrating that the essential oil was active toward Enterococcus faecalis and Staphylococcus aureus. Phytotoxic activity of essential oil was analyzed by testing interference on germination... |

| A chronic toxicity bioassay was conducted with the microcrustacean Artemia salina as the testing organism for the toxic organophosphate diazinon in order to determine if the species is an appropriate indicator of pollution in aquatic environments. Tests of animal exposure to different concentrations of the toxicant were performed for 24, 48 and 72 hours after larvae hatching. Registered mortality data was used to obtain the lethal dose 50 (LD50) of the organophosphate for each exposure time, considering the immobilization of A. salina larvae as the mortality parameter. The lethal concentration (LD50) in the same exposure times was calculated by evaluating morphological changes on the three initial stages of larval development. Both doses were determined by... |

| The development of drugs for photodynamic therapy (PDT) is an important area of research due to their growing use in medical applications. Therefore, it is important to develop new bioassay methods for PDT photosensitizers that are inexpensive, easy to handle and highly sensitive to environmental conditions. Xanthene dyes (fluorescein, rose bengal B, erythrosine B and eosin Y) with LED light sources were investigated using Artemia salina as a bioindicator of photodynamic activity. In this study, three factors were investigated: (i) photosensitizers concentration, (ii) the LED irradiation time and (iii) the waiting time between the addition of the photosensitizers and the beginning of the irradiation. To analyze the photo-killing of A. salina, it was... |

| Artemia salina is an extremophile species that tolerates a wide range of salinity, especially hypertonic media considered lethal for the majority of other aquatic species. In this study, A. salina cysts were hatched in the laboratory and nauplii were acclimated at three different salinities (60, 139 and 212 ppt). Once in the adult phase, their hemolymph osmolality was measured. The animals were strong hypo-osmoregulators in the entire range of tested salinities, with up to 10 fold lower hemolymph osmolalities than their surrounding environment. Immunostaining of Na+/K+-ATPase was done on sections and on whole body mounts of adults in order to localize the ionocytes in different organs. An intense Na+/K+-ATPase immunostaining throughout the cells was... |
