However, the differences between crude and purified enzymes such as thermostability, resistance to Ba(2+), Mn(2+), Hg(2+), Zn(2+), Cu(2+), 1,10-phenanthroline, 2,2′-bipyridyl, and PMSF (phenylmethylsulfonyl fluoride) were observed.

Conclusions: The results suggested the purified keratinase is predominantly extracellular proteins when strain F6 was

grown on keratinous substrates. The protease, in combination with other components, is effective in feather degradation. The strain F6 is more suitable for feather degradation than its purified keratinase.

Significance and Impact of the Study: The novel nonpathogenic Cl-amidine manufacturer T. atroviride F6 with high feather-degrading activity showed potentials in biotechnological process of converting feathers into economically useful feather meal.”
“Background: Despite optimal and early surgical treatment of non-small-cell lung cancer (NSCLC), many patients MCC 950 die of recurrent NSCLC. We investigated

the association between gene methylation and recurrence of the tumor.

Methods: Fifty-one patients with stage I NSCLC who underwent curative resection but who had a recurrence within 40 months after resection (case patients) were matched on the basis of age, NSCLC stage, sex, and date of surgery to 116 patients with stage I NSCLC who underwent curative resection but who did not have a recurrence within 40 months after resection (controls). We investigated whether the methylation of seven genes in tumor and lymph nodes was associated Phospholipase D1 with tumor recurrence.

Results: In a multivariate model, promoter methylation of the cyclin-dependent kinase inhibitor 2A gene p16, the H-cadherin

gene CDH13, the Ras association domain family 1 gene RASSF1A, and the adenomatous polyposis coli gene APC in tumors and in histologically tumor-negative lymph nodes was associated with tumor recurrence, independently of NSCLC stage, age, sex, race, smoking history, and histologic characteristics of the tumor. Methylation of the promoter regions of p16 and CDH13 in both tumor and mediastinal lymph nodes was associated with an odds ratio of recurrent cancer of 15.50 in the original cohort and an odds ratio of 25.25 when the original cohort was combined with an independent validation cohort of 20 patients with stage I NSCLC.

Conclusions: Methylation of the promoter region of the four genes in patients with stage I NSCLC treated with curative intent by means of surgery is associated with early recurrence.”
“Aim: To investigate the applicability of rpoB gene, which encodes the beta subunit of RNA polymerase, to be used as an alternative to 16S rRNA for sequence similarity analysis in the thermophilic genus Geobacillus. Rapid and reproducible repetitive extragenic palindromic fingerprinting techniques (REP- and BOX-polymerase chain reaction) were also used.
