Transthyretin, a New Cryptic Protease

Microsciadin, a New Milk-Clotting Cysteine Protease from an Endemic Species, Euphorbia microsciadia

In the present work, a new branch of biotechnological advantage of the latex of an endemic perennial plant, Euphorbia microsciadia has been introduced. A novel cysteine protease, designated as microsciadin, was purified from the latex of Euphorbia microsciadia by a combination of sequential usage of SP-Sepharose Fast Flow column in two different pHs and a final gel filtration ...

Oculoleptomeningeal amyloidosis associated with a new transthyretin variant Ser64.

BACKGROUND A Canadian family with oculoleptomeningeal amyloidosis with both central and peripheral nervous system disorders was described in 1988. Death of affected family members resulted from recurrent cerebral hemorrhage. OBJECTIVE To determine if oculoleptomeningeal amyloidosis is caused by a mutation in transthyretin (prealbumin). METHODS DNA isolated from peripheral blood and archival...

A Sympatric Cryptic Species of Mammal: a New Species

-A new species of bat from the genus Rhogeessa is described, which would not have been recognized as distinct if the karyotypes had not been available. The discovery of this species clearly documents that it is possible for two sympatric species of mammals to be so similar in external and cranial morphology that without chromosomal, genic, or some other data, a researcher would never realize a ...

A New Cryptic Lactura from Texas (Lepidoptera, Zygaenoidea, Lacturidae)

A new species of Lactura is described from Texas: Lactura rubritegulasp. n. Identity of the new species can be reliably determined by both larval and adult characters, CO1 haplotypes, and its late-spring period of flight activity. Male genitalic features overlap with those of L. basistriga (Barnes & McDunnough, 1913), whereas female structures differ markedly between the pair. The new Sideroxyl...
