Bioprinting In article 2203021 by Carlos Mota and co-workers, a polysaccharide-based hydrogel human mesenchymal stromal cell spheroids are combined to obtain bioink. Using the spheroid-based bioink, contructs were bioprinted successfully differentiated post-bioprinting cartilagelike tissues.

The tracking technique is one of the most critical techniques in wireless sensor network applications. The methodology of most recently proposed tracking schemes is to predict the object locations based on a single object moving model, and periodically activate nearby sensors to monitor the target. In most real-world situations, a target moves with different movement patterns, and thus, accurat...

MotA and MotB are integral membrane proteins that form the stator complex of the proton-driven bacterial flagellar motor. The stator complex functions as a proton channel and couples proton flow with torque generation. The stator must be anchored to an appropriate place on the motor, and this is believed to occur through a putative peptidoglycan-binding (PGB) motif within the C-terminal peripla...

The polar flagellum of Vibrio alginolyticus rotates remarkably fast (up to 1,700 revolutions per second) by using a motor driven by sodium ions. Two genes, motX and motY, for the sodium-driven flagellar motor have been identified in marine bacteria, Vibrio parahaemolyticus and V. alginolyticus. They have no similarity to the genes for proton-driven motors, motA and motB, whose products constitu...

A locus encoding polypeptides associated with flagellar structure and function was identified, sequenced, and characterized in Treponema phagedenis and Treponema pallidum. This locus includes homologs of the FlgD, FlgE, MotA, MOB, FliL, and FliM polypeptides found in Salmonella typhimurium and Bacillus subtilis. These polypeptides are extensively conserved between the two treponemes. Several ad...

Campylobacter jejuni is an important cause of bacterial diarrhea worldwide. The pathogenesis of C. jejuni is poorly understood and complicated by phase variation of multiple surface structures including lipooligosaccharide, capsule, and flagellum. When C. jejuni strain 81-176 was plated on blood agar for single colonies, the presence of translucent, non-motile colonial variants was noted among ...

This paper proposes two novel motion-vector based techniques for target detection and target tracking in surveillance videos. The algorithms are designed to operate on a resource-constrained device, such as a surveillance camera, and to reuse the motion vectors generated by the video encoder. The first novel algorithm for target detection uses motion vectors to construct a consistent motion mas...

Pseudomonas aeruginosa causes severe respiratory tract infections in patients with cystic fibrosis (CF). We have been examining nonopsonic phagocytosis of P. aeruginosa by macrophages. To study the P. aeruginosa-macrophage interaction at the molecular level, we have constructed a transposon Tn5G bank in a clinical isolate of P. aeruginosa (strain 4020) and identified mutants resistant to nonops...
