We report evidence of a novel mechanism by which polychlorinated biphenyls might act as potent inducers of inflammation. Aroclor 1242 (A1242), a polychlorinated biphenyl mixture, and 2,2',4,4'-tetrachlorobiphenyl (PCB47), a constituent of A1242 that produces the same patterns of effects, impaired the oxidative burst of human neutrophils by inhibiting the antioxidant enzyme superoxide dismutase,...

In the present study, collagen was obtained from tissues of invasive sea urchin (Diadema setosum) rapidly spreading in Mediterranean. As a result, yield isolated determined to be 23.78±1.33% (dry weight). According SDS-Page (Sodium Dodecyl Sulfate-Polyacrylamide gel electrophoresis) analysis, it contains (α1)2α2, (Molecular Weight (MW) 124, 114 kDa) resembling calfskin and ß chains (MW 245 kDa)...

A nivel Metodológico, una tipo básica, descriptivo, diseño no experimental transeccio...

The Eastern tropical Pacific holds extensive oxygen minimum zone (OMZ) areas where pelagic denitrification occurs. Sedimentary nitrogen isotopes are believed to record their history, which provides indirect evidence for the past extent of upper ocean depletion. We present a new high-resolution sedimentary δ 15 N ODP Site 1242 located in Equatorial during Mid-Pleistocene Transition. shows increa...

ABSTRACT An analysis of the Large Magellanic Cloud (LMC) WC4 star BAT99-9 (HD 32125, FD 4, Brey 7, WS 3) shows that still contains photospheric nitrogen. Three N emission features (N v ??1238, 1242, iv ?1719, and ??3479–3485) are unambiguously identified in spectrum. cmfgen models yield an N/C ratio 0.004 ± 0.002 (by number) a C/He $0.15_{-0.05}^{+0.10}$. Due to similarity other stars, good fit...
