Background/Aim: Glioblastomas (GBMs) are the most malignant primary brain tumor. New treatment strategies against disease urgently needed, as therapies not completely efficient. In this study, we evaluated antitumorigenic activity of carotenoid fucoxanthin (Fx) on human GBM cells in vitro. Materials and Methods: GBM1 cell viability proliferation was assessed by MTT reduction, Ki67 single cloning assays. migration invasion were analyzed wound healing Transwell Apoptosis necrosis flow...
Summary Recent ornithological surveys of humid forest remnants in the Serra da Ouricana near Boa Nova, southern Bahia, Brazil, revealed existence an as yet unnoticed montane Atlantic avifauna. Among 220 species recorded, 27 represent range extensions several hundred kilometres, others were preceded only by single or a few old, disputed records from and at least two are undescribed taxa. A portion this avifauna has been recorded other mountainous areas interior Bahia (Chapada Diamantina,...
Summary The goal of this study was to use GC‐MS and UHPLC‐UV‐VIS‐based metabolomic tools combined with chemometric analysis discriminate between fruit blackspot physiological disorder independently storage condition (regular air or controlled atmosphere) without (hereafter referred as ‘Control’). looked at polar metabolites, enzymes, fatty acids oxidative stress markers. Fruit high levels lenticel damage are more likely develop blackspot, which appears be exacerbated by H 2 O peroxidation...
Presence of toxic compounds in marine coastal waters has increased exponentially since Industrial Revolution. In this way, we aimed to evaluate biochemical and physiological changes occurring within Hypnea musciformis after short-term exposure gasoline. was cultivated without gasoline then exposed various concentrations it (0.001 % - 1.0 %, v/v) for periods 30 min, 1 h, 12 h 24 h. A Pricncipal Compound Analysis UV-vis spectral window (200-700 nm) able discriminate gasoline-exposed samples...
We report the rediscovery of Cherry-throated Tanager Nemosia rourei in southern Espírito Santo, Brazil, February 1998, and first substantive observations its behaviour, vocalizations other aspects natural history. Approximately 10 individuals, occasionally groups up to five birds, were located humid montane forest at 1,100 m a.s.l. privately owned “Fazenda Pindobas IV” (20°19′S, 41°17′W). This small population appears be safe, as property owners are preserving remaining native there, hope...
This work evaluated the biofloc technology cultivation of Ulva ohnoi on its growth performance and biocompounds contents. was cultivated under an initial density 6 g·L-1 for 28 days using water from a tank which exchanged daily at 90% rate. Temperature, salinity, illuminance were measured daily. Algae their adjusted weekly. Results showed average plant 1.15%·day-1 (49.5 g·week-1). A significant difference observed when comparing (2.64 ± 0.3%) final (4.62 0.2%) ulvan concentration, in...
The analysis of fucoxanthin (FCX) in algal biomasses presents some limitations, especially regarding the sample preservation after collection until extraction pigment. FCX stability was evaluated biomass samples one diatom and three brown seaweed species (Phaeophyceae) their extracts stored at -20ºC -80ºC, for 60 days. Fucoxanthin quantified through UHPLC-DAD. methanolic micro/macroalga -80ºC were more effective preserving xanthophyll, comparatively to biomasses. Besides, chromatographic...
Abstract This work evaluated the cultivation of macroalgae Ulva ohnoi on performance algal biomass and changes in its proximate biochemical composition after a biofloc system. U. was cultivated three experimental units with aeration, heating, initial density 6 g L -1 for 28 days. The water used collected from matrix tank exchanged 90% once day throughout experiment. Temperature, salinity illuminance were measured twice day. To evaluate growth macroalgae, weekly weighing performed, daily rate...
