Absence seizures: Update on signaling mechanisms and networks
Epilepsia Open, EarlyView.Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose A single hip–knee–ankle angle (HKA) angle does not reflect the biomechanics of native, arthritic or prosthetic knees. Since HKA varies throughout flexion, dynamic coronal alignment is best represented by a kinematic curve plotting HKA against the range of motion.

RATCHETING OF STAINLESS STEEL 304 UNDER MULTIAXIAL NONPROPORTIONAL LOADING [PDF]
, 2020 Ratcheting tests are conducted on stainless steel 304 under uniaxial, torsional, and combined axial-torsional loading. The ratcheting strain is predicted based on the constitutive theory that incorporates a modified Ohno-Wang kinematic hardening rule and

Lasers in Surgery and Medicine, EarlyView.ABSTRACT Objectives Perforated appendicitis commonly results in intra‐abdominal infection requiring prolonged antibiotic therapy. Intraoperative antimicrobial adjuncts are limited, and photodynamic therapy (PDT) may provide a targeted, resistance‐independent approach.

Myosin's mechanical ratchet [PDF]
Proceedings of the National Academy of Sciences, 2006 Myosin molecular motors bind to and exert force upon actin filaments. Between 24 (1) and 37 (2) myosin subfamilies are currently recognized (3), the myriad members of which are specialized for tasks ranging from muscle contraction through to mechano-sensation and signaling, cell polarization, the sliding and tensioning of cytoskeletal elements ...

Ratchet nanofiltration of DNA [PDF]
Lab on a Chip, 2013 The DNA nanofilter is a microfabricated electrophoretic separation device consisting of a periodic array of thin slits (circa 60 nm) separated by deeper wells (circa 320 nm). We demonstrate that this device can act as a tuneable, clog-free filter when operating in a low frequency, asymmetric field inversion mode.

On the Assembly of Actin Polymerization‐Powered Motors
Macromolecular Rapid Communications, EarlyView.Actin polymerization‐powered motors have the highest speed when the actin recruiting‐polymerizing proteins are immobilized in polymer brushes on their surface. These motors orbit around larger tracer particles at pH above the isoelectric point of ActA but dock onto the tracer particles’ surface at lower pH. ABSTRACT Nano‐ and micromotors are a class of
