The cholix toxin gene (chxA) was first identified in V. cholerae strains in 2007, and the protein was identified by bioinformatics analysis in 2008. It was identified as the third member of the diphtheria toxin group of mono-ADP-ribosyltransferase toxins along with P. aeruginosa exotoxin A and C. diphtheriae diphtheria toxin. Our group determined the structure of the full-length, three-domain c...

03 "Monumentality," she vmtes, "creates the sense of social cohesion that is central to the consolidation of a community by impressing upon people the importance and power of a thing or a person Central to this impression of social power is the sense of long-lastingness; the perception that this city, building, institution, or artwork—and the values it represents— will last through generations,...

The Peters family is a Yale family, and Jack Peters' branch of the family extended to five generations at Yale when my third daughter, Barbara, received her M.D. degree, with honors, in 1979. We trace our origins back to when Andrew Peters came to America from England in 1702 and settled in Andover, Massachusetts. Our family's Yale connection goes back to Jack's grandfather, Thomas McClure Pete...

Nowadays smartphones and tablets are used nearly everywhere at any time. The need for mobile networks with high bandwidth increases fast as all of those network elements require Internet connection for almost all applications. The radio access technologies ranging from GSM over UMTS to the currently upcoming LTE networks become more and more complex and with it the effort of controlling this co...

During his visit to the American University of Beirut, I was indeed lucky when Professor Holmdahl MH invited me to his Department of Anaesthesiology, University Uppsala, Sweden. I was also, doubly honored and surprised when the internationally famous Professor asked me not to call him Professor Holmdahl, “call me Martin and I call you Anis”. His invitation to me to spend the first week of my vi...

Serine-arginine-rich (SR) proteins play a key role in alternative pre-mRNA splicing in eukaryotes. We recently showed that a large SR protein called Son has unique repeat motifs that are essential for maintaining the subnuclear organization of pre-mRNA processing factors in nuclear speckles. Motif analysis of Son highlights putative RNA interaction domains that suggest a direct role for Son in ...

The auditory brainstem nuclei, angularis (NA), magnocellularis (NM), and laminaris (NL) of the chicken, Gallus, contain terminals that stain for antibodies against the inhibitory neurotransmitter, gamma-aminobutyric acid (GABA). Some of these terminals originate from cells surrounding nucleus magnocellularis. Results from this study indicate that the majority of the GABAergic terminals found in...
