Epoxyoctadecadienoic Acids from Crepis Conyzaefolia Seed Oil
The seed oil of Crepis eonyzaefolia (Gouan) Daile Torre contains previously unidentified (± )-eis-12,13epoxyoctadeca-trans-6-cis-9-dienoic (14 and eis-12,13-epoxyoctadeca-cis-6-cis-9-dienoic (2 ~{) acids and the more common vernolic [( ±)-12,13-epoxyoctadec-cis-9-enoic] (32 %) acid.
متن کاملInfluence of the Presence of B Chromosomes on DNA Damage in Crepis capillaris
The sensitivity of different plant species to mutagenic agents is related to the DNA content and organization of the chromatin, which have been described in ABCW and bodyguard hypotheses, respectively. Plant species that have B chromosomes are good models for the study of these hypotheses. This study presents an analysis of the correlation between the occurrence of B chromosomes and the DNA dam...
متن کاملThree-dimensional organization of chromosomes of Crepis capillaris by optical tomography.
The three-dimensional (3D) organization of chromosomes of Crepis capillaris (2n = 6) has been investigated. Root tips were fixed, macerated with enzymes and gently separated without squashing. The cells were then stained with DAPI and optically sectioned under computer control. Sections were stored as video images and processed to remove noise and out-of-focus information. Computer modelling wa...
متن کاملToxicity of Crepis lacera in grazing ruminants
BACKGROUND Crepis lacera is a plant from the Asteraceae family that is common in the Mediterranean region. Farmers believe that this plant may be deadly to small ruminants in areas of southern Italy. However, scientific evidence is lacking, and no proof exists that C. lacera is toxic to ruminants. Necropsies conducted on four sheep revealed lesions in their livers and kidneys. RESULTS In the ...
متن کاملFurther Experimental Studies in Tetany
It has been our aim to determine in what particular the blood is altered during tetany so that it can produce hyperexcitability of the motor nerves. As a working hypothesis it has been assumed that (1) there may be a lack of calcium in the blood and tissues; (2) there may be a circulating poison which like an oxalate could render inactive the circulating calcium; and (3) there may be a substanc...
