Anticancer Properties of Essential Oils and Other Natural Products
Blowman, K.; Magalhães, M.; Lemos, M. F. L.; Cabral, C.; Pires, I. M.Essential oils are secondary metabolites with a key-role in plants protection, consisting primarily of terpenes with a volatile nature and a diverse array of chemical structures. Essential oils exhibit a wide range of bioactivities, especially antimicrobial activity, and have long been utilized for treating various human ailments and diseases. Cancer cell prevention and cytotoxicity are exhibited through a wide...
Reproductive trade-offs in a temperate reef fish under high pCO2 levels
Faria, A. M.; Lopes, A. F.; Silva, C. S. E.; Novais, S. C.; Lemos, M. F. L.; Gonçalves, E. J.Fishes are currently facing novel types of anthropogenic stressors that have never experienced in their evolutionary history, such as ocean acidification. Under these stressful conditions, energetically costly processes, such as reproduction, may be sacrificed for increased chances of survival. This trade-off does not only affect the organism itself but may result in reduced offspring fitness. In the present st...
Effects of imidacloprid exposure on Chironomus riparius Meigen larvae: linking ...
Azevedo-Pereira, H. M. V. S.; Lemos, M. F. L.; Soares, A. M. V. M.Imidacloprid (IMI) is an insecticide that interferes with the transmission of stimuli in the nervous system of insects. It is neurotoxic by mimicking nicotine through its binding to the nicotinic acetylcholine receptor. In this work, experiments comprising 96 h exposure followed by 48 h in clean medium were conducted to evaluate the toxicity of IMI to Chironomus riparius and its potential recovery. Behavioural ...
Developmental toxicity of endocrine disrupters bisphenol A and vinclozolin in a...
Lemos, M. F. L.; van Gestel, C. A. M.; Soares, A. M. V. M.Studies of the effects of endocrine-disrupting compounds (EDCs) on invertebrates are still largely underrepresented. This work aims to fill this gap by assessing the effects of bisphenol A (BPA) and vinclozolin (Vz) on the terrestrial isopod Porcellio scaber (common rough woodlouse). Male adult and sexually undifferentiated juvenile woodlice were exposed to the toxicants. Effects on molting regime and growth we...
Reproductive toxicity of the endocrine disrupters vinclozolin and bisphenol A i...
Lemos, M. F. L.; van Gestel, C. A. M.; Soares, A. M. V. M.Endocrine Disruptor Compounds (EDCs) have been largely studied concerning their effects on vertebrates. Nevertheless, invertebrates as targets for these chemicals have been neglected and few studies are available. Specifically for edaphic invertebrates, data concerning the effects of EDCs is residual. Influences of EDCs on the reproduction systems of these organisms, with consequences at the population level, a...
