Resumen
We describe a tunable double-clad Yb-doped fiber laser based on a long period fiber grating mechanically induced in a section of single mode holey fiber inserted into the laser cavity. The mechanically induced long period holey fiber grating acts as a wavelength-selective fiber filter whose central wavelength, linewidth, and strength can be tuned by changing the period, the length of the grating, and the applied pressure. The fiber laser gives a ? 12.6 nm tuning range, from ? 1079:4-1092nm, with slope efficiencies of 18.7-26.3% at this wavelength range, with respect to the launched pump power.

Armendariz-Borunda, J.",,"2000",,"Background/Aims: Excess type I collagen accumulation is a major feature of fibrotic diseases such as liver cirrhosis. Reversion of this disease has not been fully accomplished. Pbysiologically, collagen is degraded by interstitial collagenases, neutrophil collagenase (MMP-8) being the most active against type I collagen. Introduction of MMP-8 gene into liver cells could be an advantageous tool to potentiate fibrosis degradation. Methods: We cloned latent and active MMP-8 genes in prokaryotic and eukaryotic expression vectors and an adenoviral vector. Transfection of MMP-8 in HepG2 was effectuated by CaPO4, polylysine-lactose (P-L) and adenoviral transduction, and cells and culture supernatant were harvested 72 h after transfection for analysis of MMP-8 expression by reverse transcription-polymerase chain reaction and collagenolytic activity. Results and Conclusions: We show that a truncated neutrophil collagenase (tMMP-8) backing a portion of the carboxy terminus and with an intact aminoterminus (latent; l-tMMP-8) or a truncated amino terminus (active; a-tMMP-8) has enzymatic activity against native type I collagen, and the activity was inhibited by EDTA, 1,10-phenanthroline and TIMP-1. Both MMP-8 mRNA (latent and active) were detected by polymerase chain reaction in cells transfected with CaPO4, P-L and adenoviral transduction; however, relative expression of MMP-8 was enhanced when the plasmid was delivered as a P-L complex and increased by adenoviral infection. Finally, a-tMMP-8 cDNA was cloned in a vector under transcriptional control of a reguiated promoter (PEPCK-a-tMMP-8). HepG2 cells, transfected with the PEPCK-a-tMMP-8 plasmid DNA up-regulated expression of: A-tMMP-8 after incubation of the cells with butyryl-cAMP and glucagon, while stimulation with insulin slightly down-regulated its expression. Recombinant MMP-8 expressed by HepG2-transduced cells can efficiently degrade soluble type I collagen, which is potentially useful for gene transfer therapies.",,,,,,"10.1016/S0168-8278(00)80307-4",,,"http://hdl.handle.net/20.500.12104/45491","http://www.scopus.com/inward/record.url?eid=2-s2.0-0033762968&partnerID=40&md5=49c4717ef675295f867b92e53320d3f5",,,,,,"5",,"Journal of Hepatology",,"758 763",,"33",,"Scopus WOS",,,,,,"Active MMP-8; Collagen; Collagenase; Gene transfer",,,,,,"Truncated active matrix metalloproteinase-8 gene expression in Hepg2 cells is active against native type I collagen",,"Article"

The novelties belong to Cosmos section Discopoda and are described and illustrated. Morphologically, Cosmos pseudoperfoliatus resembles C. jaliscensis, C. peucedanifolius, C. palmeri and C. scabiosoides, but differs from them in having 4-7 leaf pairs on the stem, leaves tomentose on both faces, trullate external phyllaries, yellow disk florets with 4-5 lobes, and corky-tuberculate achenes. On the other hand, Cosmos ramirezianus is morphologically similar to C. montanus, but differs by its coriaceous and pinnatisect leaves, yellow internal phyllaries, yellow disk florets with light purple lobes, and by the persistence of paleae during fruiting. Phenology, distribution and habitat are provided as well as a key for the identification of the species in Cosmos section Discopoda. " 2013 Magnolia Press.
