Heterotropic regulation and negative homotropic cooperativity

open access: yesFEBS Open Bio, EarlyView.
We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Epilepsy‐Associated Variants of a Single SCN1A Codon Exhibit Divergent Functional Properties

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Pathogenic variants in SCN1A, which encodes the voltage‐gated sodium channel NaV1.1, are associated with multiple epilepsy syndromes exhibiting a range of clinical severity. SCN1A variants are reported in different syndromes, including Dravet syndrome, which is associated with loss‐of‐function, whereas neonatal/infantile‐onset ...

Research on the selection of rotation stopping block’s arrangement for single-type low-floor tram

open access: yes机车电传动, 2022
Single-type low-floor trams have been widely used in the construction of urban light rail transit in recent years. As a common component of low-floor trams, the rotation stopping block can limit the relative swing angle range between the car body and the

Effectiveness of rTMS on Working Memory and Inhibitory Impairments in Patients With Post‐Stroke Executive Deficits

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Stem Cell Transplantation in Friedreich Ataxia: Cure for Leukemia but No Effect on Neurological Progression

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Friedreich Ataxia (FRDA) is a neurodegenerative disorder of children and young adults associated with cardiomyopathy and other systemic complications. We report a 10‐year‐old girl who presented simultaneously with Acute Myelogenous Leukemia and FRDA who was successfully treated for her leukemia with allogeneic hematopoietic stem cell ...

Three-dimensional comparative strain analysis of the capsuloligamentous complex during passive glenohumeral motion

open access: yesJournal of Orthopaedic Surgery and Research
Background Understanding the three-dimensional biomechanical behavior of the capsuloligamentous complex, considering it as a single sheet of fibrous tissue, is beneficial for assessing patients with limited glenohumeral range of motion in vivo.
