Upon induction, Bacillus megaterium 216 produces the bacteriocin megacin A-216, which leads to lysis of the producer cell and kills B. megaterium and a few other bacterial species. The DNA region responsible for megacinogeny was cloned in B. megaterium. The nucleotide sequence of a 5,494-bp-long subfragment was determined, and the function of the genes on this fragment was studied by generating...

A CO(1-0) on-source spectrum of the well-known carbon star IRC +10 216 taken with the IRAM 30m telescope in June 1996 shows excess emission between –18.3 and –14.3 km s −1 at the red wing of the underlying profile. The excess emission is confirmed in January 1997 but is absent in April 1997 and June 1998 IRAM spectra. Such a transient feature has not been seen before in this star or any other A...

We extend the result of Lemma 4, [1] to case that e = 0 and ℓ 1 which was missing in but used proof Theorem 1, .

Whether structural changes of the erythrocyte membrane increase the susceptibility to hemolysis particularly of the relatively older cell population during the early phase of a 216-km ultrarace was tested in six male runners (age 53.6 +/- 10.4 yr, height 175.8 +/- 11.1 cm, body mass 75.9 +/- 8.4 kg). Erythrocyte membrane spectrins were lowest (P < 0.001) after 42 km (75.59 +/- 5.25% of prerace)...

Tumors induced in mice by UV radiation often express highly immunogenic tumor-specific transplantation antigens (TSTA). The 216 gene, which encodes a TSTA of the C3H tumor UV-1591, has been cloned and characterized as a novel major histocompatibility complex Class I antigen. The purpose of this study was to determine whether the 216 gene-encoded TSTA can function as a tumor rejection antigen wh...

The skeleton's osteogenic response to mechanical loading can be affected by loading duration and rest insertion during a series of loading events. Prior animal loading studies have shown that the cortical bone response saturates quickly and short rest insertions between load cycles can enhance cortical bone formation. However, it remains unknown how loading duration and short rest insertion aff...
