Neurons of cerebellar nuclei in the rat brain had a marked surface coat which was stained with cationic iron colloid or aldehyde fuchsin. Neurons with a similar surface coat were also noted in the retrosplenial cortex. The surface coat was stained doubly with cationic iron colloid and aldehyde fuchsin. Digestion with hyaluronidase eliminated the stainability of the surface coat to both agents. ...

1. The variability of species combinations and membership assembly patterns in an insect pre-dispersal seed predator guild were studied at various spatial and temporal resolutions using presence/absence and abundance data in null models. The guild consists of seven beetle species (four bruchids and three curculionids) and one moth species that live on a perennial vetch, Vicia tenuifolia Roth (L...

The author investigated aquatic fungi developing on the seeds of some plants in various types of water bodies of Podlasie Province. The bait method was used to isolate the fungi. Seventy-four aquatic fungal species were found on seeds of three species of plants: Cannabis sativa hemp-seeds 59, Fagopyrum esculentum buckwheat-seeds 55 and on Vicia sativa vetch-seeds 44 in water of four various bod...

In the cerebral cortex, the plant lectin Vicia villosa (VVA) selectively stains the surfaces of nonpyramidal neurons. This lectin binds specifically to alpha- and beta-linked N-acetylgalactosamine (GalNac). VVA-reactive carbohydrate is highly concentrated in layer 4 of the primary visual cortex of the cat, where it is associated exclusively with GABAergic local circuit neurons. We have studied ...

Experiments were conducted at three sites across southern New South Wales, Australia, over years (2008 to 2010), evaluate the agronomic and quality parameters of two wheat (Triticum aestivum L.), barley (Hordeum vulgare oat (Avena sativa L.) one triticale (× Triticosecale) variety, grown as monocultures or in combination with purple vetch (Vicia benghalensis L.). Harvests occurred when individu...

a long-term rotation experiment was established in 2001 to compare conservation or reduced tillage systems (shallow rototiller and chisel tillage) with conventional tillage system using mouldboard plough in a semi-arid region with mediterranean climate. field experiments were conducted to determine weed density and profitability of cropping systems in a crop rotation of winter wheat (triticum a...

Chondroitin sulfate proteoglycans (CSPGs) of the extracellular matrix help stabilize synaptic connections in the postnatal brain and impede regeneration after injury. Here, we show that a CSPG of the lectican family, versican, also promotes presynaptic maturation in the developing brain. In the embryonic chick optic tectum, versican is expressed selectively by subsets of interneurons confined t...

Murine L3T4 T cells freshly isolated from Peyer's Patch were fractionated based on differential adherence to Vicia villosa agglutinin (VVA). VVA adherent cells secreted IL-5, but not IL-2, after stimulation with Con A and IL-1. In striking contrast, VVA nonadherent PP L3T4 T cells secreted IL-2, but not IL-5, under the same conditions. In addition, supernatants from VVA adherent, but not from V...
