ExsD is a negative regulator of the Pseudomonas aeruginosa type III secretion regulon

ML McCaw, GL Lykken, PK Singh… - Molecular …, 2002 - Wiley Online Library
Expression of the Pseudomonas aeruginosa type III secretion system is induced by contact
with eukaryotic cells, serum or low Ca 2+ concentrations. We report that ExsD, a unique …

A novel anti‐anti‐activator mechanism regulates expression of the Pseudomonas aeruginosa type III secretion system

N Dasgupta, GL Lykken, MC Wolfgang… - Molecular …, 2004 - Wiley Online Library
Expression of the Pseudomonas aeruginosa type III secretion system (TTSS) is coupled to
the secretion status of the cells. Environmental signals such as calcium depletion activate the …

A secreted regulatory protein couples transcription to the secretory activity of the Pseudomonas aeruginosa type III secretion system

ML Urbanowski, GL Lykken… - Proceedings of the …, 2005 - National Acad Sciences
The type III secretion system (T3SS) of Pseudomonas aeruginosa is an important virulence
determinant. Transcription of the T3SS is highly regulated and intimately coupled to the …

Anyonic superconductivity

JD Lykken, J Sonnenschein, N Weiss - Physical Review D, 1990 - APS
The renormalized Chern-Simons term at finite density is shown to vanish when the renormalized
coefficient at zero density takes values Ne 2 2 π. Thus in the Chern-Simons description …

Square‐wave analysis of skin impedance

DT Lykken - Psychophysiology, 1970 - Wiley Online Library
A method is described for studying skin impedance phenomena, based on analysis of waveforms
of current through the skin produced by square voltage pulses. In several experiments, …

Kaluza-Klein states from large extra dimensions

T Han, JD Lykken, RJ Zhang - Physical Review D, 1999 - APS
We consider the novel Kaluza-Klein (KK) scenario where gravity propagates in the (4+ n)-dimensional
bulk of spacetime, while gauge and matter fields are confined to the (3+ 1)-…
