[14C]Cadaverine was applied to leaves of Lupinus polyphyllus, L. albus, L. angustifolius, L. perennis, L. mutabilis, L. pubescens, and L. hartwegii and it was preferentially incorporated into lupanine. In Lupinus arboreus sparteine was the main labelled alkaloid, in L. hispanicus it was lupinine. A pulse chase experiment with L. angustifolius and L. arboreus showed that the incorporation of cad...

The genus Habroteleia Kieffer is revised. Seven species are recognized, three are redescribed: H. flavipes Kieffer, H. persimilis (Kozlov & Kononova), H. ruficoxa (Kieffer); and four species are described as new: H. mutabilis Chen & Talamas, sp. n., H. salebra Chen & Talamas, sp. n., H. soa Chen & Talamas, sp. n., and H. spinosa Chen & Johnson, sp. n. Four species are treated as junior synonyms...

A Streptomyces strain MS-6-6 with promising anti-tuberculous activity was isolated from soil samples in Saudi Arabia. The nucleotide sequence of its 16S rRNA gene (1426 bp) evidenced a 100% similarity to Streptomyces mutabilis. Through an anti-tuberculous activity-guided approach, a polyketide macrolide was isolated and identified as treponemycin (TP). The structure of the isolated compound was...

BACKGROUND Nummular eczema is an idiopathic inflammatory skin disease that mostly has a chronic and relapsing course. Many factors are thought to be responsible for this condition, such as atopic dermatitis, dry skin, emotional stress or seasonal variation. OBJECTIVE The purpose of the study was to assess clinical findings and aggravating factors of nummular eczema and to evaluate characteris...
