We investigated the in vitro effects of citrulline (0.1, 2.5 and 5.0 mM) and ammonia (0.01, 0.1 and 1.0 mM), and the influence of resveratrol (0.01 mM, 0.1 mM and 0.5 mM) on pyruvate kinase, citrate synthase, succinate dehydrogenase (SDH), complex II, and cytochrome c oxidase activities in cerebral cortex, cerebellum and hippocampus homogenates of 60-day-old male Wistar rats. Results showed that 2.5 and 5.0 mM citrulline decreased pyruvate kinase activity in cerebral cortex and, at a concentration of 5.0 mM, increased its activity in hippocampus. Additionally, 5.0 mM citrulline increased citrate synthase activity in the cerebellum of rats. Citrulline (5.0 mM) reduced complex II and cytochrome c oxidase activities in cerebral cortex and hippocampus. With regard to ammonia, at 0.1 and 1.0 mM, decreased complex II activity in cerebral cortex and at 1.0 mM decreased its activity in cerebellum and hippocampus. Ammonia (1.0 mM) also decreased cytochrome c oxidase activity in cerebral cortex and cerebellum of rats. Resveratrol was able to prevent most of the alterations caused by these metabolites in the biomarkers of energy metabolism measured in the cerebrum of rats. Data suggest that these alterations in energy metabolism, caused by citrulline and ammonia, are probably mediated by the generation of free radicals, which can in turn be scavenged by resveratrol.There is disagreement about whether the locomotor activity produced by serotonin (5-HT) 1A/1B receptor agonists is ultimately mediated through a dopaminergic mechanism or is independent of dopamine (DA) system functioning. Using a developing rat model, we examined whether DA neurotransmission is necessary for the locomotor activity produced by 5-HT1A/1B receptor stimulation. Depending on experiment, male and female preweanling rats were pretreated with vehicle, the monoamine-depleting agent reserpine, the 5-HT synthesis inhibitor 4-chloro-DL-phenylalanine methyl ester hydrochloride (PCPA), the DA synthesis inhibitor ∝-methyl-DL-p-tyrosine (AMPT), or the D1 and D2 receptor antagonists SCH 23390 and raclopride, respectively. After completing the pretreatment regimen, the behavioral effects of saline and the 5-HT1A/1B receptor agonist RU 24969 were assessed during a 2-h test session. Locomotor activity in the center and margin of the testing chamber was recorded. RU 24969's locomotor activating effects were sensitive to blockade of the D2 receptor, but not the D1 receptor. The DA synthesis inhibitor (AMPT) significantly attenuated the RU 24969-induced locomotor activity of preweanling rats, as did the 5-HT synthesis inhibitor PCPA. The latter result suggests that presynaptic 5-HT1A/1B receptors may have a role in mediating RU 24969-induced locomotion during the preweanling period. selleck kinase inhibitor DA neurotransmission, especially involving D2 receptors, is necessary for the 5-HT1A/1B-mediated locomotor activity of preweanling rats. The actions of PCPA, reserpine, and SCH 23390 differ substantially between preweanling and adult rats, suggesting that the neural mechanisms underlying these DA/5-HT interactions vary across ontogeny.Apatinib is a novel, highly selective small-molecule inhibitor of the tyrosine kinase VEGFR-2. Although its safety and efficacy in the treatment of advanced gastric cancer (GC) and other solid tumors have been confirmed, the precise molecular mechanism underlying its efficacy remains unclear. The purpose of this study was to investigate the mechanism by which apatinib regulates the biological functions of GC cells in vitro. The CCK-8 assay was used to detect the inhibitory effect of apatinib at different concentrations on the proliferation of SGC7901 and MKN45 human GC cells. The effects of apatinib on apoptosis, autophagy, and cell cycle-related genes in SGC7901 and MKN45 cells were detected by Western blotting and real-time quantitative PCR (RT-qPCR). JC-1 staining, flow cytometry, Hoechst 33342 staining, dansylcadaverine (MDC) staining, and Transwell assays were used to detect the effects of apatinib on apoptosis, the cell cycle, autophagy, and invasion and migration capacities, respectively, in SGC7901 and MKN45 cells. The inhibitory effect of apatinib on the proliferation of GC cells was dependent on concentration. Apatinib significantly promoted apoptosis and autophagy. It also altered the cell cycle distribution and inhibited the invasion and migration of GC cells. In general, apatinib inhibited the proliferation of GC cells by promoting apoptosis and autophagy, regulating the cell cycle and inhibiting the invasion and migration capacities of GC cells.We analysed the Horizon 2020 project database, currently the European Union's (EU) largest framework programme for research and innovation-nearly 80 billion euros available over 7 years (2014-2020), to estimate the amount and type of EU-supported biomedical and health research and funding distribution among EU member states and non-European countries. Out of 20,877 projects as of 14th January 2019, a total of 4865 projects were classified as human health related. Ninety-four countries/territories worldwide participated in at least one biomedical project. The EU-15 original member states showed the highest participation as project leaders/partners and for acquired funding. Strong unequal funding distribution and participation between EU-15 and the 13 newest members-with EU-15 receiving about 87% of funding and EU-13 only 3%-have been evidenced. For both EU-15 and EU-13 we detected about 20% of projects involving the public and private sectors, according to Horizon 2020 guidelines. The largest percentage of projects was in the areas of biotechnological research (28.28%) and "basic research" (26.95%); these two sectors together accounted for 46.99% of the total funding assigned (7.9 billion euros). Research in neurosciences and neurological diseases appeared to be an increasing study area. Neurological and mental diseases covered about 21% of projects. Epidemiological studies accounted for about 5% of the total projects and for 14% of funding. Strong correlations were shown by indicators of financial and scientific capacity to identify success rates in obtaining EU funding, making the gap between countries with strong and weak research infrastructures difficult to overcome.
