Evidence suggests that idiopathic Parkinson’s disease (PD) is the consequence of a neurodevelopmental disruption, rather than strictly a consequence of aging. Thus, we hypothesized that maternal supplement of omega-3 polyunsaturated fatty acids (ω-3 PUFA) may be associated with neuroprotection mechanisms in a self-sustaining cycle of neuroinflammation and neurodegeneration in lipopolysaccharide (LPS)-model of PD. To test this hypothesis, behavioral and neurochemical assay were performed in prenatally LPS-exposed offspring at postnatal day 21. To further determine whether prenatal LPS exposure and maternal ω-3 PUFAs supplementation had persisting effects, brain injury was induced on PN 90 rats, following bilateral intranigral LPS injection. Pre- and postnatal inflammation damage not only affected dopaminergic neurons directly, but it also modified critical features, such as activated microglia and astrocyte cells, disrupting the support provided by the microenvironment. Unexpectedly, our results failed to show any involvement of caspase-dependent and independent apoptosis pathway in neuronal death mechanisms. On the other hand, learning and memory deficits detected with a second toxic exposure were significantly attenuated in maternal ω-3 PUFAs supplementation group. In addition, ω-3 PUFAs promote beneficial effect on synaptic function, maintaining the neurochemical integrity in remaining neurons, without necessarily protect them from neuronal death. Thus, our results suggest that ω-3 PUFAs affect the functional ability of the central nervous system in a complex way in a multiple inflammation-induced neurotoxicity animal model of PD and they disclose new ways of understanding how these fatty acids control responses of the brain to different challenges.

Miconia rondoniensis occurs in secondary upland (terra firme) moist open forest in the Brazilian states of Rondônia, Mato Grosso and Amazonas. It can be recognized by the tree habit, large leaves with rounded to obtuse or subcordate bases and 5+2 basal veins (five main veins plus a faint submarginal pair), large inflorescences with proximal paraclades bearing quaternary branches and distal paraclades bearing tertiary branches, persistent hemi-elliptic bracteoles, short persistent calyx lobes, and capitate stigmas. The most striking feature of this new species is the thick pubescence on the branches and petioles, composed of trichomes having a long axis and short arms at the base, but inflated and lacking arms at the apex, resulting in a sorus-like surface covered with globose structures.

A new species belonging to the previously monotypic genus Panca Evans, 1955, P. moseri Dolibaina, Carneiro & O. Mielke sp. nov., from grasslands areas of Peru, Bolivia and Brazil is described. Adults and male and female genitalia of the new species are illustrated, described in detail, and compared with the type species of the genus, Lerodea subpunctuli Hayward, 1934, and with its externally most similar and sympatric species, Vidius mictra Evans, 1955. The systematic position of the genus Panca and its association with lowland open natural habitats of South America are discussed.
