Perineuronal Nets (PNNs) are specialized extracellular matrix structures of the brain that are found around specific neurons. PNNs play a role in structural and developmental plasticity, it remains unknown how they are affected by drugs of addiction. In the US, drug use has a very profound impact medically, economically, and socially. We used a conflict model which mimicked human drug seeking b...

Molecular markers have become a useful tool simplifying and speeding up breeding work. They are also helpful in the genetic analysis of complex agronomic traits. The investigations concern the use of already available SCAR markers for molecular analysis of breeding materials. The markers are the apple powdery mildew resistance gene Pl2, originating from Malus zumi, and the apple scab resistance...

Collection data and biological information is presented on the Fergusobia (Nematoda: Neotylenchidae)/ Fergusonina (Diptera: Fergusoninidae) mutualism inducing galls on Angophora in Australia. Three species and two morphospecies have been recognised. Fergusobia colbrani Davies n. sp. is described from soft spheroid leaf galls on Angophora floribunda. It is characterised by a combination of morph...

A great increase in hybridization frequency of cultured rodent cells was obtained when conventional cell fusion using 50% polyethylene glycol (PEG) was combined with a cell agglutination produced by plant lectins. The rate of appearance of hybrid colonies was found to be correlated with the extent of cell agglutination by lectin, as well as with cell fusion induced by subsequent PEG treatment. ...

Isolates of Campylobacter jejuni, C coli, C fetus and C laridis were tested for agglutination reactions with a panel of five lectins: Arachis hypogaea, Bauhinia purpurea, Solanum tuberosum, Triticum vulgaris and Wisteria floribunda. Twenty three patterns of agglutination (lectin types) were recorded among 376 isolates. Patterns were consistent and reproducible. Only 4.5% of isolates were untypa...

Alchornea cordifolia leaves are used ethno-botanically for the treatment of bacterial and fungal infections. The present study is aimed at investigating antimicrobial wound-healing effects gel formulation from ethyl acetate liquid fractions ethanol leaf extract cordifolia. was subjected to liquid-liquid fractionation using n-heptane acetate. fraction further vacuum chromatography (VLC) by gradi...
