12,4-Dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-onel DIMBOA was extracted with ethyl acetate from acidified water homogenates of corn (Zea mays L.) seedlings. Pure DIMBOA or ethyl acetate extracts of corn tissue were added to bacterial growth medium at five concentrations (measured as hydroxamates). DIMBOA and corn extracts were more inhibitory to soft rot bacteria (Erwinia spp.) that are nonp...

The basidiomycete Laetiporus sulphureus var. miniatus belongs to the Aphyllophorales, Polyporaceae, and grows on the needleleaf tree. The fruiting bodies of Laetiporus species are known to produce N-methylated tyramine derivatives, polysaccharides, and various lanostane triterpenoids. As part of our ongoing effort to discover biologically active compounds from wood-rotting fungi, an anti-inflam...

The validity of the published description of Hyla rufitela is questioned because the origin of the described tadpoles does not correspond to the distribution of this species. The present description, based on tadpoles that were hatched from two egg masses from the Caribbean lowland of Costa Rica, includes tadpoles raised to adult frogs to verify the species. The newly described tadpoles differ ...

recurring "innovations" in institutional reform, T. G. Davies on Ernest Jones (not quite the demolition job that the Introduction implies), and Virginia Berridge on the vicissitudes of the disease model of addiction. James Birley's 1974 lecture, the first in the book, compares the work of psychiatrists and painters; Berrios's entire essay (1988), the last, can be read as an amplification of Bir...

Furanoterpenoid accumulation in response to microbial attack in rotting sweetpotatoes has long been linked to deaths and lung edema of cattle in the world. However, it is not known whether furanoterpenoid ipomeamarone accumulates in the healthy-looking parts of infected sweetpotato storage roots. This is critical for effective utilization as animal feed and assessment of the potential negative ...

An indigenous wood rotting edible Lentinus kauffmanii isolated from Keeriparai forest of Western Ghats was studied for extracellular peroxidase production. Peroxidases are major extracellular lignolytic enzymes involved in lignocellulosic degradation. Physical factors such as pH, temperature and nutritional factors such as carbon, nitrogen sources and amino acids were standardized for the growt...
