Methods for the control of wandering Jew (Tradescantia fluminensis) are reviewed and one selected to eradicate this weed from a forest remnant near the lower Rangitikei River. The botanical importance of the forest is assessed in the context of Manawatu Plains Ecological District. Its future conservation management is related to other problem weeds, notably Cobaea scandens, Solanum jasminoides,...

OBJECTIVE The development of vertebrae is a complex phenomenon that is correlated with distinct morphological and biochemical alterations in the paraxial mesenchyme and glycoconjugates. The purpose of this study is to investigate the glycosylation pattern in paraxial mesenchyme-forming vertebrae by using the lectin histochemical technique. MATERIALS AND METHODS In this descriptive-analytic st...

Trypanosoma cruzi at various stages of maturation and differentiation have been isolated by conventional cellular fractionation procedures and characterized by cell surface markers using 30 highly purified lectins encompassing all known sugar specificities. Cell surface carbohydrates of the various T. cruzi stages were analyzed by agglutination and lectin-binding assays. Specific receptors for ...

Thursday, July 12, 1849, was a pleasant summer day in the hamlet of Bond Head, Ont., 40 miles north of Toronto. For most of the locals — largely Irish Protestants — it was a festive occasion featuring a parade in memory of William of Orange, a celebration traditionally lubricated with fiery homebrew. Mrs. Featherstone Osler’s lack of interest in these proceedings is easily understood: she was b...

The turkey sperm glycocalyx is known to contain residues of sialic acid, alpha-mannose/alpha-glucose, alpha- and beta-galactose, alpha-fucose, alpha- and beta-N-acetyl-galactosamine, monomers and dimers of N-acetyl-glucosamine, and N-acetyl-lactosamine. Potential changes in these carbohydrates during in vitro semen storage at 4 degrees C were evaluated using males of both high- and low-sperm-mo...

As part of the extracellular matrix (ECM), perineuronal nets (PNs) are polyanionic, chondroitin sulfate proteoglycan (CSPG)-rich coatings of certain neurons, known to be affected in various neural diseases. Although these structures are considered as important parts of the neurovascular unit (NVU), their role during evolution of acute ischemic stroke and subsequent tissue damage is poorly under...
