New taxa are described from Grus canadensis tabida: Brephosceles petersoni sp. n. (Alloptidae); Pseudogabucinia reticulata sp. n. (Kramerellidae); Geranolichus canadensis sp. n., and Gruolichus wodashae, gen. et sp. n. (Pterolichidae). Observations on resource partitioning by these mites are given.

Generally, heavy metals enter into the aquatic environment through atmospheric deposition, erosion of geological matrix or due to anthropogenic activities caused by industrial effluents, domestic sewage and mining wastes. The present study analyzed the concentration of seven elements (Cd, Cu, Mn, Ni, Pb, Zi and Hg) in eight seaweeds such as Centrocerous clavutum, Sargassum wightii, Colpemenia s...

We have proposed that the basal ganglia act as the central switching mechanism for the action selection system of the vertebrate brain. Simulation of our functional model of basal ganglia demonstrated that their output was consistent with this action selection hypothesis. Here we extend this model by incorporating anatomically-inspired local inhibitory axon collateral networks into two basal ga...

Senna reticulata (Willd.) H. S. Irwin & Barneby (Fabaceae) is a pioneer tree which colonizes open areas in Amazonian floodplains. It is very abundant throughout Amazonia along the nutrientrich whitewater rivers, and can be considered to be one of the most efficient colonizers of open areas. It possesses a very high tolerance towards flooding of the roots and stem, and performs extremely high ph...

Introduction Parkinson’s disease is a progressive neurodegenerative movement disorder characterized by reduction and slowness of movement (akinesia and bradykinesia), muscle rigidity, and tremor. The core pathology of the disease is the degeneration of midbrain dopaminergic neurons in the substantia nigra pars compacta that project to the striatum and other basal ganglia nuclei. The striatum is...

ABSTRACT. This work aimed to investigate, for the first time, chemical composition and cytotoxicity of Dillenia reticulata King’s essential oil. The oil was obtained through hydrodistillation, its volatile components were analyzed gas chromatography (GC-FID) chromatography-mass spectrometry (GC-MS) techniques. Twelve components, which constitutes more than 99.49% content, successfully identifie...
