Early hyperthyroidism induces an aberrant growth of hippocampal mossy fibers both in the fascia dentata (supragranular layer) and in Ammon's horn (infrapyramidal layer of CA3). Using a quantitative autoradiographic method, we found a corresponding increase in kainic acid binding sites supporting previous observations of a very close association between mossy fiber terminals and kainic acid bind...

Curtisia dentata is used in African traditional medicine to treat variety of infections. C. dentata leaves were collected from Buffelskloof Nature Reserve, South Africa. The ethanol, chloroform, ethyl acetate and acetone extracts were evaluated for antimicrobial activity using micro dilution assay against Escherichia coli, Pseudomonas aeruginosa, Mycobacterium smegmatis, Mycoplasma hominis, Can...

Three new pterosins, named as semipterosin A (1), B (2) and C (3), together with 11 known pterosins (4–14), were isolated from the aerial parts of Pteris semipinnata. Their structures elucidated by HRESI-MS, NMR spectral data, CD literature comparisons. assessed for their anti-inflammatory activity. Compounds 1–3 inhibited NF-kB induction 40.7%, 61.9% 34.0%, respectively. This is first report i...

Plant species capable of hyper-accumulating heavy metals are of considerable interest for phytoremediation, and differ in their ability to accumulate metals from the environment. This work aims to examine (i) arsenic accumulation in three fern species [Chinese brake fern (Pteris vittata L.), slender brake fern (Pteris ensiformis Burm. f.), and Boston fern (Nephrolepis exaltata L.)], which were ...

BACKGROUND Morphological and ploidy changes of the arsenic hyperaccumulator, Chinese brake fern (Pteris vittata) callus tissue are described here to provide insight into fern life cycle biology and for possible biotechnology applications. Pteris vittata callus was studied using transmission and scanning electron microscopy, and flow cytometry. RESULTS Callus induction occurred both in light a...
