Pfl : Progress Report ?

چکیده
Even the unimplemented language can be useful. By writing programmes using the language, one achieves a disciplined and structured programming style which is hard to attain in a less structured environment. The programmes can later be translated by hand into some other language. This approach was found to be very successful in a trial by a class of engineering students, using the first version of PFL; programmes were written more easily, and worked correctly sooner, than similar programmes written directly in assembly languages (3).

Pediatric-type nodal follicular lymphoma: an indolent clonal proliferation in children and adults with high proliferation index and no BCL2 rearrangement.
Pediatric follicular lymphoma (PFL) is a variant of follicular lymphoma (FL) presenting as localized lymphadenopathy in children. Unlike conventional adult FL, PFL typically does not recur or progress. Clear diagnostic criteria for PFL are lacking, and it is uncertain whether this indolent lymphoma is defined by age or may occur in adults. We analyzed 27 FL in patients < 40 years of age and fou...

متن کاملThe iron-sulfur cluster of pyruvate formate-lyase activating enzyme in whole cells: cluster interconversion and a valence-localized [4Fe-4S]2+ state.
Pyruvate formate-lyase activating enzyme (PFL-AE) catalyzes the generation of a catalytically essential glycyl radical on pyruvate formate-lyase (PFL). Purified PFL-AE contains an oxygen-sensitive, labile [4Fe-4S] cluster that undergoes cluster interconversions in vitro, with only the [4Fe-4S](+) cluster state being catalytically active. Such cluster interconversions could play a role in regula...
متن کاملLET's sponge: How the lncRNA PFL promotes cardiac fibrosis
Compared to their protein-coding counterparts, almost nothing is known about the role of long noncoding RNAs (lncRNAs) in cardiac fibrosis. In the current report, Liang and Pan et al. characterized the pro-fibrotic lncRNA PFL in respect to cardiac fibrosis in mice. PFL was upregulated in the hearts of mice after myocardial infarction and in fibrotic cardiac fibroblasts. Moreover, PFL competitiv...
متن کاملInactivation of E. coli pyruvate formate-lyase: role of AdhE and small molecules.
Escherichia coli AdhE has been reported to harbor three distinct enzymatic activities: alcohol dehydrogenase, acetaldehyde-CoA dehydrogenase, and pyruvate formate-lyase (PFL) deactivase. Herein we report on the cloning, expression, and purification of E. coli AdhE, and the re-investigation of its purported enzymatic activities. While both the alcohol dehydrogenase and acetaldehyde-CoA dehydroge...
