A 38 year old patient with megalencephaly, mental retardation, and lifelong tremor developed levodopa responsive parkinsonism in his mid-30s followed by the appearance of dyskinesiae, motor fluctuations, hallucinations, and dementia. Brain MRI showed, as well as other changes, iron deposition in the globus pallidus, substantia nigra, and the pulvinar of the thalamus. Postmortem examination disc...

Introduced fishes comprise a substantial fraction of the fish fauna in 2 Bexar County waters: 35% in upper San Antonio River and 43% in Braunig Reservoir. Four species (Astyanax mexicanus, Poecilia latipinna, P. formosa, and Cichlasoma cyanoguttatum) are south Texas fishes displaced northward. Two species (Cyprinodon variegatus and Menidia beryllina) are recent introductions from estuarine wate...

Host plant resistance to the Diaprepes root weevil, Diaprepes abbreviatus (L.) was assessed for seedlings of 54 Poncirus trifoliata (L.) Raf. selections and two families of progeny from crosses between Citrus and P. trifoliata. Weight gain was consistently lower when larvae were reared in pots containing the progeny of Citrus reticulata Blanco 'Sunki' x P. trifoliata 'Flying Dragon' compared wi...

The hesionid polychaete Hesione reticulata von Marenzeller, 1879 was described from Enoshima Island, Japan and has been recorded also from the Red Sea. Depending on researchers, it has been regarded as either a distinct species or synonymous with older established ones. The type specimen has been lost. In order to clarify its taxonomic status, Hesione reticulata is herein redescribed, illustrat...

The pathogenic effects of Pratylenchus coffeae on growth and yield of tangelo (Citrus paradisi x C. reticulata) scions grafted on rough lemon (C jambhiri), sour orange (C. aurantium) and 'Cleopatra' mandarin (C. reticulata) rootstocks were evaluated under field conditions for 4 years. Pratylenchus coffeae on inoculated trees increased to significantly damaging population densities on rough lemo...

--This study examined habituation of the predator inspection behavior in the guppy (Poecilia reticulata) and its relationship with boldness (open field locomotion). Two different strategies were discovered: (1) initial inspection of a predatorlike fish, correlated with boldness; (2) subsequent surveillance, governed by a random underlying process and unrelated with boldness. The surveillance in...

El objetivo de este estudio fue analizar el crecimiento inicial a mediano plazo un asentamiento P. reticulata bajo diferentes dosis fósforo. experimento se llevó cabo en área del Bosque Atlántico, Sooretama, norte estado Espírito Santo, Brasil. Se probaron cinco P por árbol (0 g, 27 47 67 g y 87 g) diseño bloques al azar con tres repeticiones 18 plantas parcela. A los 3 meses, 9 meses 15 midió ...

Following behaviour among Neotropical stream fishes have been scarcely reported. This type of feeding association was observed in a small stream in the upper rio Paraná system between the catfish, Aspidoras fuscoguttatus, acting as a nuclear species, and Knodus moenkhausii, Poecilia reticulata, and Astyanax altiparanae as follower species. Aspidoras fuscoguttatus individuals dug in the bottom d...

Oil-resin fractions from Copaifera reticulata Ducke (Leguminosae-Caesalpinoideae) were evaluated for larvicidal activity on third larval instars of Aedes aegypti, in searching for alternative control methods for this mosquito. The bioactive fractions were chemically monitored by thinlayer chromatography, H and C nuclear magnetic resonance and mass spectrometry. Bioassays were performed using fi...

Antioxidant potential of leaves of three different species of Annona was studied by using different in vitro models eg., 1,1-diphenyl-2-picryl hydrazyl (DPPH), 2,2-azinobis-(3-ethylbenzothizoline-6-sulphonate) (ABTS), nitric oxide, superoxide, hydroxy radical and lipid peroxidation. The ethanolic extract of A. muricata at 500 microg/ml showed maximum scavenging activity (90.05%) of ABTS radical...
