Efeito do estresse hídrico e salino na germinação e vigor de sementes de maxixe

The objective of this work was to evaluate the germination and vigor of two lots of gherkin seeds in different osmotic potentials using polyethylene glycol (PEG 6000) and sodium chloride (NaCl). Seeds of the 'North' cultivar were sown in germitest paper moistened in solutions of polyethylene glycol and sodium chloride in osmotic potentials of 0, -0.3, -0.6 and -0.9MPa. The experimental design was completely randomized in a factorial 2x4 design (solutions x osmotic potential), with four replications. Seed vigor was evaluated by the germination test, first germination count, length and dry weight of root and hypocotyl. It is concluded that the reduction in osmotic potential from -0.3MPa induced by PEG 6000 and NaCl reduces the germination and vigor of gherkin's seeds. The osmotic stress induced by PEG 6000 produced more severe effects than saline in physiological quality of gherkin's seeds.

Selective protection of the cerebellum against intracerebroventricular LPS is mediated by local melatonin synthesis

Although melatonin is mainly produced by the pineal gland, an increasing number of extra-pineal sites of melatonin synthesis have been described. We previously demonstrated the existence of bidirectional communication between the pineal gland and the immune system that drives a switch in melatonin production from the pineal gland to peripheral organs during the mounting of an innate immune response. In the present study, we show that acute neuroinflammation induced by lipopolysaccharide (LPS) injected directly into the lateral ventricles of adult rats reduces the nocturnal peak of melatonin in the plasma and induces its synthesis in the cerebellum, though not in the cortex or hippocampus. This increase in cerebellar melatonin content requires the activation of nuclear factor kappa B (NF-κB), which positively regulates the expression of the key enzyme for melatonin synthesis, arylalkylamine N-acetyltransferase (AA-NAT). Interestingly, LPS treatment led to neuronal death in the hippocampus and cortex, but not in the cerebellum. This privileged protection of cerebellar cells was abrogated when G-protein-coupled melatonin receptors were blocked by the melatonin antagonist luzindole, suggesting that the local production of melatonin protects cerebellar neurons from LPS toxicity. This is the first demonstration of a switch between pineal and extra-pineal melatonin production in the central nervous system following a neuroinflammatory response. These results have direct implications concerning the differential susceptibility of specific brain areas to neuronal death.
