Effects of 17 beta-estradiol on early gonadal development and expression of genes implicated in sexual differentiation of a South American teleost, Astyanax altiparanae
(Elsevier B.V., 2020-10-01)
Gonadal sex differentiation in teleost fish shows greater plasticity as compared to other vertebrates, as it can be influenced by a variety of factors such as exogenous sex steroids. Exogenous estrogens, such as 17 ...
4-Methylesculetin, a natural coumarin with intestinal anti-inflammatory activity, elicits a glutathione antioxidant response by different mechanisms
(2020-01-05)
4-methylesculetin (4 ME) is a natural antioxidant coumarin with protective effects on the intestinal inflammation, in which oxidative stress plays a key role in its aetiology and pathophysiology. Based on this, we examined ...
Neither altered incubation temperature during fetal development nor preferred rearing temperature improves leg bone characteristics of broilers
(2020-10-01)
The present study evaluated whether broiler femoral and tibiotarsal characteristics (as assessed at slaughter age) could be improved if birds were reared under their preferred temperature and whether continuous high or low ...
CB1 and CB2 receptors in the bed nucleus of the stria terminalis differently modulate anxiety-like behaviors in rats
(2021-08-30)
The endocannabinoid system is implicated in anxiety, but the brain sites involved are not completely understood. The bed nucleus of the stria terminalis (BNST) has been related to anxiety and responses to aversive threats. ...
Chemotherapy drugs and inflammatory cytokines enhance matrix metalloproteinases expression by oral mucosa cells
(2021-07-01)
Objective: Oral mucositis (OM), the most common side effect of cancer therapy, is associated with pro-inflammatory cytokines and matrix metalloproteinases (MMPs) increased expression. Although there are approaches for OM ...
Warming weakens facilitative interactions between decomposers and detritivores, and modifies freshwater ecosystem functioning
(Wiley-Blackwell, 2018-07-01)
Warming is among the major drivers of changes in biotic interactions and, in turn, ecosystem functioning. The decomposition process occurs in a chain of facilitative interactions between detritivores and microorganisms. ...
Favourable effects of Bacillus subtilis and Bacillus licheniformis on experimental periodontitis in rats
(2016-06-01)
Objectives The purposes of this study were to evaluate, in rats: i) the effects of Bacillus species on the development of experimental periodontitis (EP) via microtomographic, immunological and hematological assays (Experiment ...
EFFECT OF FOOD SHORTAGE ON GROWTH, ENERGETIC RESERVES MOBILIZATION, AND WATER QUALITY IN JUVENILES OF THE REDCLAW CRAYFISH, CHERAX QUADRICARINATUS, REARED IN GROUPS
(Crustacean Soc, 2014-09-01)
The aim of this study is to analyze the impact of food shortage on growth performance, by means of energetic reserves (proteins, glycogen and lipids) mobilization and hepatopancreas cells analysis in C. quadricarinatus ...
Specific parameters of infrared LED irradiation promote the inhibition of oxidative stress in dental pulp cells
(2021-11-01)
Objectives: The present study aimed to assess the oxidative stress and the viability of dental pulp cells stimulated by lipopolysaccharide (LPS) and submitted to photobiomodulation (PBM) with infrared light-emitting diode ...
Interaction of epigallocatechin-gallate and chlorhexidine with Streptococcus mutans stimulated odontoblast-like cells: Cytotoxicity, Interleukin-1β and co-species proteomic analyses
(2021-11-01)
Objectives: The dentin therapeutic agent chlorhexidine has inflammatory and cytotoxic characteristics urging investigation of alternatives like the natural compound epigallocatechin-gallate. The aim is to verify the effect ...
