At least 70% of the afferents to substantia nigra dopaminergic neurons are GABAergic. The vast majority of these arise from the neostriatum, the external globus pallidus and the substantia nigra pars reticulata. Nigral dopaminergic neurons express both GABA(A) and GABA(B) receptors, and are inhibited by local application of GABA(A) or GABA(B) agonists in vivo and in vitro. However, in vivo, syn...

BACKGROUND AND AIMS Plathymenia reticulata (Leguminosae) is a Brazilian tree that occurs in two biomes: Cerrado, a woody savanna vegetation, and the Atlantic Forest, a tropical forest. In this study, phenological patterns and their variability within and among populations located in these biomes and in transitional zones between them were assessed. METHODS During a 15-month period, individual...

Satsuma mandarin (Citrus unshiu Marc.), Hallabong [(C. Marc. × C. sinensis Osb.)×(C. reticulata Blanco)], Cheonhyehyang [((C. unshiu×C. sinensis)×C. reticulata)×(C. reticulate×C. sinensis)], and Redhyang (citrus hybrid 'Kanpei), which are citrus hybrids, mostly consumed in Korea. The flavor of peel depends on the composition content volatile essential oils. Limonene, ?-terpinene, ?-myrcene, lin...

The includes three species of Azolla (A. andreisii sp. nov., A. coloniensis, and 1), two Azollopsis intermedia tomentosa), Crybelosporites pannuceus, Gabonisporis cristata, Ghoshispora sp., Grapnelispora loncochensis, Molaspora (M. lobata M. reticulata), Paleoazolla pata...

Histopathological changes in gills of a native fish Capoeta aculeata, naturally-infected with parasites were studied. The specimens (15.5 to 22.8 cm) were collected from Choghakhor lagoon in West Iran. 35 (11%) of the total 318 studied fishes were infected with gill parasites. Overall, six protozoan and metazoan parasite species were collected from fishes including Ichthyophthirius multifiliis,...

The present work was conducted to isolate and identify different parasites from Indian Major Carp (IMC) Catla catla. During the study period the severity of infection and Parasitic Frequency Index (PFI, %) were also estimated in terms of months, seasons and length groups of fishes. For the investigative purpose different districts of West Bengal were selected considering the potential of fisher...

This study investigated the health of natural stocks of the oyster Crassostrea rhizophorae on the southern coast of Bahia in northeastern Brazil, during summer and winter 2010, at three localities (sampling points) in the estuaries of the Maraú (Camamu Bay) and Graciosa rivers. A total of 180 oysters (30/sampling point/season) were examined macroscopically for the presence of pathogens and anat...

BACKGROUND Mosquitoes transmit serious human diseases, causing millions of death every year. Vector control is facing a threat due to the emergence of resistance to synthetic insecticides. Insecticides of botanical origin may serve as suitable alternative biocontrol techniques in the future. Nine different locally available medicinally important plants suspected to posse larvicidal property wer...

The present study investigates the HPLC profiling of phenolic compounds, and antioxidant activities of Annona reticulata. Through HPLC assay, high levels of rutin hydrate (603.88 mg/100 g extract) and moderate amount of catechin, epicatechin, and p-coumeric acid were determined (99.00, 78.19, 85.38 mg/100 g extract, respectively). Some amount of vanillic acid, ellagic acid, and quercetin were a...
