Structure and Function of the Bi-Directional Bacterial Flagellar Motor

Biomolecules, 2014
The bacterial flagellum is a locomotive organelle that propels the bacterial cell body in liquid environments. The flagellum is a supramolecular complex composed of about 30 different proteins and consists of at least three parts: a rotary motor, a ...

Bistable molecular conductors with a field-switchable dipole group

, 2002
A class of bistable "stator-rotor" molecules is proposed, where a stationary bridge (stator) connects the two electrodes and facilitates electron transport between them.

Euler-Lagrange models with complex currents of three-phase electrical machines and observability issues [PDF]

, 2009
A new Lagrangian formulation with complex currents is developed and yields a direct and simple method for modeling three-phase permanent-magnet and induction machines. The Lagrangian is the sum a mechanical one and of a magnetic one.

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.

Damping seal for turbomachinery [PDF]

, 1985
A damping seal between a high speed rotor member and stator member that separates pressurized fluid compartments is described. It is characterized by the rotor member having a smooth outer surface and the stator member having its bore surface roughened ...

Incidence and Outcome of Infants With Cancer in Canada: A Report From Cancer in Young People in Canada Database

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Infants with cancer are rare and face unique challenges. Our study aims to describe the incidence of infantile cancers in Canada and to compare treatment‐related mortality (TRM) and their outcomes with those of older children. Methods We conducted a retrospective cohort study using the Cancer in Young People in Canada database ...

The Dynamic Ion Motive Force Powering the Bacterial Flagellar Motor

Frontiers in Microbiology, 2021
The bacterial flagellar motor (BFM) is a rotary molecular motor embedded in the cell membrane of numerous bacteria. It turns a flagellum which acts as a propeller, enabling bacterial motility and chemotaxis.

Evaluating the Genetic Overlap Between Congenital Heart Disease and Neuroblastoma Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Children with congenital heart disease (CHD) have elevated neuroblastoma (NB) risk, potentially due to shared neural crest origins. We analyzed rare exonic de novo single‐nucleotide variants in 702 CHD and 454 NB trios from the Neuroblastoma Epidemiology in North America Study, Gabriella Miller Kids First Program, and a published cohort. Seven
