We present two cases of rare human poisoning in one family following ingestion of cooked leaves from the tobacco tree plant, Nicotiana glauca. The toxic principle of N. glauca, anabasine (C10H14N2), is a small pyridine alkaloid, similar in both structure and effects to nicotine, but appears to be
Calnexin (CNX) is an integral membrane protein of endoplasmic reticulum (ER) and is a critical component of ER quality control machinery. It acts as a chaperone and ensures proper folding of newly synthesised glycoproteins. CNX shares a considerable homology with its luminal counterpart calreticulin
Harpins are bacterial protein elicitors that induce hypersensitive response-like necrosis when infiltrated into nonhost plants such as tobacco (Nicotiana tabacum L.) (Z.-M. Wei, R.J. Laby, C.H. Zumoff, D.W. Bauer, S.Y. He, A. Collmer, S.V. Beer [1992] Science 257: 85-88). Activity of a 49-kD
The polyadenylation signal of rice tungro bacilliform virus (RTBV) was characterized by mutational and deletion analysis. The cis-acting signals required to direct polyadenylation conformed to what is known for plant poly(A) signals in general and were very similar to those of the related
It will be well to restate the main problem at this point and to examine how far the accumulated data can help to elucidate it. The problem is this: Why are old mice generally resistant to all forms of peripheral inoculation of vesicular stomatitis virus when intracerebral injection is equally fatal
In 1850 the Belgian Count Hypolyte Visart de Bocarmé was accused of having killed his brother-in-law Gustave Fougnies by poisoning with nicotine. Bocarmé had isolated nicotine from tobacco leaves (Nicotiana tabacum). J. S. Stas (1813-1891) was committed expert and managed to convince the poisoner.
"Mimi-bukuro" is a book written by Moriyasu Negishi in the Edo period. M. Negishi (1737-1815) was a magistrate in the town of Edo. He was very much interested in listening and recording many kinds of stories, which were told by the various kinds of people, such as public officers, samurais,
