Fungus produces a toxic surprise

The newly isolated endophytic fungus Paraconiothyrium sp. LK1 produces ascotoxin.

We have isolated five endophytic fungi from the roots of Capsicum annuum, Cucumis sativus and Glycine max. The culture filtrates (CF) of these endophytes were screened on dwarf mutant rice (Waito-C) and normal rice (Dongjin-byeo). Endophyte CAC-1A significantly inhibited the growth of Waito-C and Dongjin-byeo. Endophyte CAC-1A was identified as Paraconiothyrium sp. by sequencing the ITS rDNA re...

Standard ultrasound has a poor accuracy in the detection of carotid plaque surface irregularities and ulcers, which are features of vulnerable lesions. Sonographic contrast agents can improve vessel wall lumen definition, thus potentially overcoming this limitation. Recent studies also suggest that contrast ultrasound can be used to study intraplaque neovascularizaion, a potential marker of hig...
