Tumorilysin was found in diffusion chambers implanted s.c. or i.p. in A/BiF/F50+, DBA/2J and C57BL/6J mice. Chambers with 0.45-micrometer pores implanted s.c. were most densely covered by a syncytium of macrophages and had the most consistently active tumorilysin, compared with smaller-pored chambers or those implanted i.p. The lysin acted on cultures of murine sarcomas induced by foreign bodie...

BACKGROUND The present study aimed to compare the safety and efficacy for novices to conduct intubation with the Bonfils intubation fiberscope (BIF) using the transillumination-assisted or midline approach technique in patients with normal airways. METHODS In this prospective randomized control study, 10 trainees were assigned to the transillumination-assisted technique group (T group) or the...

Banded iron formations (BIFs) record a time of extensive Fe deposition in the Precambrian oceans, but the sources and pathways for metals in BIFs remain controversial. Here, we present Fe- and Nd-isotope data that indicate two sources of Fe for the large BIF units deposited 2.5 billion y ago. High-εNd and -δ(56)Fe signatures in some BIF samples record a hydrothermal component, but correlated de...

AIMS The potential use of bifidobacteria as indicators for faecal contamination was studied along a sheep meat production and processing chain. The levels of bifidobacteria were compared with those of Escherichia coli. Total viable counts were followed along the chain (244 samples). METHODS AND RESULTS Forty-three per cent of the samples contained bifidobacteria, of which 15% were solely dete...

T he topic of the “credit crunch” received considerable attention during the early 1990s. As a result, several initiatives aimed at eliminating regulatory disincentives to lending were put in place. For example, documentation requirements recently were reduced to the legal minimum for loans to small and medium-sized businesses. Also, examiners and bankers were encouraged to emphasize the charac...

The non-intercepting Beam Induced Fluorescence (BIF) monitor for transverse beam profile measurements was successfully tested for different ion species and energies from 5 to 750 MeV/u at the GSI accelerators [1]. Starting from its first implementation [2] we systematically investigated technical aspects such as the proper choice of optics and gain factors, as well as physical aspects like the ...

Evidence of Earlyto Mid-Cryogenian (c. 780 Ma and c. 740 Ma) glacial activity is summarized for the northern Arabian–Nubian Shield (ANS), including structural framework, stratigraphy, lithological descriptions and relationships with younger and older units, banded iron formation chemostratigraphy, other characteristics, geochronological constraints, and discussion. The ANS is a broad tract of j...

The Endengue Banded Iron Formation (BIF) is located in the northwestern edge of Congo craton Cameroon. Here, we report geochemical data trace and rare earth elements (REE) BIF samples from Archean Ntem complex investigate their environmental setting. Two types occur at area, both containing minimal contamination terrestrial material. Total REE (ΣREE) contents Type 1 are extremely low, ranging 0...

Interactions between water and ferrous rocks are known to generate natural H 2 in oceanic continental domains via the oxidation of iron. Such generation has been mainly investigated through alteration Fe 2+ -silicate some -carbonates. So far, magnetite ( α -Fe 3 O 4 ) never considered as a potential source mineral for since it is by-product every chemical reaction leading formation , despite be...
