Graphis upretii is a new lichen species discovered in Vietnam. The species is characterized by a loosely corticate, rough, whitish grey to greyish green thallus, elongate and irregularly branched lirellae with an apically thin complete thalline margin (negrosina morph), laterally carbonized, entire proper exciple, clear hymenium, hyaline, 16~20 transversely locular ascospores, and about 50~95 ×...

Nucleotide sequence of the psbK gene of the cyanobacterium Synechocystis 6803 The psbK gene is found in chloroplast, cyanelle and cyanobacterial genomes (1-3). It encodes a low molecular weight photosystem H-associated polypeptide (1). This gene is closely linked to the psbl gene in chloroplast genomes. We have previously reported the isolation and restriction mapping of a Synechocystis 6803 AE...

Extracts from the seed of the African shea tree Vitellaria paradoxa C.F. Gaertn have been used traditionally for the treatment of arthritic conditions. However, little is known about the mechanisms by which benefit is conferred. This single-site, 15-week randomized, double-blind, parallel, placebo-controlled study examined a range of biomarkers in 89 patients with osteoarthritis of the knees an...

Distribution data describing the current shea range were obtained from John Hall (University of Wales, Bangor); for details, see previous reports and Vitellaria paradoxa: a monograph (Hall et al., 1996). In 2010, these records were supplemented with shea plot data from Burkina Faso, Mali and Ghana, and with the collection localities of herbarium specimens held at the Royal Botanic Gardens, Kew ...

The presence of thioredoxin was demonstrated in 20 strains of cyanobacteria as well as in one phototrophic bacterium Rhodopseudomonas sulfidophila and in Thiobacillus denitrificans. Thioredoxin activity was not found in Cyanophora paradoxa and in Porphyridium cruentum using the thioredoxin-dependent PAPS-sulfotransferase activity from Synechococcus 6301 as assay system.

Vitellaria paradoxa (C.F.Gaertn.) is a multi-purpose tree species distributed in narrow band across sub-Saharan Africa.
