Extracellular vesicles (EVs), including exosomes, play a key role in inter and intracellular communication, promoting the proliferation and invasion of recipient cells to support tumor growth and metastasis. Metastasis comprises multiple steps that first include the detachment of tumor cells through epithelial to mesenchymal transition (EMT), allowing the physical dissemination to distant organs. Thereafter, cancer-derived exosomes are still critical components for preparing the tumor microenvironment by (i) enabling tumor cells to escape from the immunological surveillance and (ii) arranging the pre-metastatic site for the engraftment of detached cancer cells...

BACKGROUND: - Abbreviation of preoperative fasting to 2 hours with maltodextrin (CHO)-enriched beverage is a safe procedure and may enhance postoperative recovery. Addition of glutamine (GLN) to CHO beverages may include potential benefits to the metabolism. However, by adding a nitrogenous source to CHO beverages, gastric emptying may be delayed and increase the risk of bronchoaspiration during anesthesia. OBJECTIVE: - In this study of safety, we aimed at investigating the residual gastric volume (RGV) 2 hours after the intake of either CHO beverage alone or CHO beverage combined with GLN...

Paracoccidioidomycosis is the most prevalent systemic mycosis in Latin America, yet few therapeutic options exist. Our aim was to search for new compounds with high efficacy, low toxicity, shorter treatment time and affordable cost. We studied two synthetic 6-quinolinyl chalcones, 3b and 3e, to determine their effects on VERO cells, antifungal activity, survival curve, interaction with other drugs and phenotypic effects against several isolates of Paracoccidioides spp. In this study, we verified that the compounds were not toxic, exhibited superior in vitro activity compared with that shown by trimethoprim-sulfamethoxazole, and after 5 days of treatment, decreased the fungal cell viability by approximately 70%...

Toxigenic Dinophysis spp. are obligate mixotrophic dinoflagellates that require a constant supply of prey-Mesodinium rubrum-to achieve long-term growth by means of kleptoplasty. Mesodinium rubrum is, however, a fast moving, jumping ciliate exhibiting an effective escape response from suspensivorous predators. In the present study, a series of laboratory experiments evaluating the motility and survival of M. rubrum in the presence of Dinophysis cells and/or substances contained in their culture medium was designed, in order to assess the mechanisms involved in prey capture by Dinophysis spp...

Pavlovian aversive conditioning requires learning of the association between a conditioned stimulus (CS) and an unconditioned, aversive stimulus (US) but also involves encoding the time interval between the two stimuli. The neurobiological bases of this time interval learning are unknown. Here, we show that in rats, the dorsal striatum and basal amygdala belong to a common functional network underlying temporal expectancy and learning of a CS-US interval. Importantly, changes in coherence between striatum and amygdala local field potentials (LFPs) were found to couple these structures during interval estimation within the lower range of the theta rhythm (3-6 Hz)...

Altered metabolism, associated with acidification of the extracellular milieu, is one of the major features of cancer. As pH regulation is crucial for the maintenance of all biological functions, cancer cells rely on the activity of lactate exporters and proton transporters to regulate their intracellular pH. The major players in cancer pH regulation are proton pump ATPases, sodium-proton exchangers (NHEs), monocarboxylate transporters (MCTs), carbonic anhydrases (CAs) and anion exchangers (AEs), which have been shown to be upregulated in several human malignancies...
