Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

An Unusual Mechanism of Closure of Muscular Ventricular Septal Defects
Case Reports in Pediatrics, 2017 Ventricular septal defects (VSDs) are the most common congenital heart defects. Most of the small or moderate size (

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein
FEBS Letters, EarlyView.Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Spontaneous closure of branchial sinus of the pyriform fossa [PDF]
BMJ Case Reports, 2018 Management of third and fourth branchial cleft anomalies are similar. These anomalies should be suspected in a child with recurrent low-anterior neck abscess. Investigations in the form of cross-sectional studies and examination of the pharynx under anaesthesia will facilitate diagnosis and resolution of abscess.

The ubiquitin system in normal and infected germinal center B cells
FEBS Letters, EarlyView.The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Spontaneous closure of a congenital lacrimal fistula
Journal of American Association for Pediatric Ophthalmology and StrabismusA congenital external lacrimal fistula appears as a small aperture inferonasal to the inner canthus, exuding clear fluid. It is thought to arise from an accessory duct connected to the lacrimal sac. Various operations have been described for ablation of congenital lacrimal fistula, but no prior study has documented spontaneous closure.

FEBS Letters, EarlyView.Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...
