E3 colicinogenic cells are immune to colicin E3. A protein called "E3 immunity protein" was previously isolated from E3 colicinogenic cells and shown to prevent the E3-induced in vitro inactivation of ribosomes. We now show that the structural gene for E3 immunity protein resides on the Col E3 plasmid, a plasmid which is present in E3 colicinogenic cells and carries the structural gene for coli...

As the number of systems which offer annotations on digital documents increases, robust anchoring of annotations is a key challenge. It is especially important if the annotator lacks write-access to the document being annotated. For example, if someone makes an annotation on a web page today and the web page changes tomorrow, what happens to the annotation? One approach is simply to “orphan” th...

BACKGROUND Clinical and epidemiological studies indicate that obstructive sleep apnea syndrome (OSAS) has a strong genetic basis. OBJECTIVES To investigate the apolipoprotein E (APOE) alleles as a genetic risk factor in OSAS. METHODS A total of 73 patients (37 male) were included. All underwent full-night polysomnography and were evaluated for APOE alleles. RESULTS The mean age was 51 ± 1...
