Caesalpinia echinata seeds stored in laboratory environmental conditions lose their viability in one month whilst under low temperatures germination is maintained for 18 months of storage. These seeds are tolerant to desiccation, keeping their viability up to 0.08 gH2O.gDW-1. Since soluble carbohydrates are believed to be involved with desiccation tolerance and seed storability, the aim of this...
An investigation of the ethanolic extract from stems of Caesalpinia echinata Lam (Leguminosae-Caesalpinioideae) led to the isolation of five new cassane diterpenes along with known lambertianic acid. Their structures were determined based on spectroscopic methods. A preliminary study on leishmanicidal activity demonstrated that compounds 1, 2 and 6 were found to inhibit the growth of amastigote...
چهار گونه جدید بنام‌های: Jurinea cartilaginea, Polygonum botuliforme, Tavernieria echinata, Verbascum scoparium نامگذاری و شرح داده می‌شوند. علاوه بر این گونه‌های زیر برای اولین بار از ایران گزارش می‌گردند: Amberoba lippii, Cadaba farinosa, Chenopodium ambrosoides, Crepis aspera, Fagonia glutinosa var. glutinosa, Lomatogonium carinthiacum, Medicago intertexta var. ciliaris, Medicago rugosa, ...
CEL-III is a hemolytic lectin isolated from Cucumaria echinata. Although recombinant CEL-III (rCEL-III) expressed in Escherichia coli showed very weak hemolytic activity compared with native protein, it was considerably enhanced by refolding in the presence of Ca(2+). This suggests that Ca(2+) supported correct folding of the carbohydrate-binding domains of rCEL-III, leading to effective bindin...
PURPOSE This study was conducted to compare the prelinguistic communicative abilities of toddlers with hearing loss and without hearing loss during the 2nd year of life and shortly before the emergence of productive single-word lexicons. METHOD The participants were 28 toddlers with hearing loss who participated in an early intervention program and 92 toddlers with normal hearing at similar l...
