Exaptation, Degeneracy and Innovation [PDF]

open access: yes
In innovation processes, exaptations are innovation-development processes through which an initial attribution of new functionality to existing artifacts leads to new artifacts and eventually new markets.

Sex‐Stratified Association of Regional Dopamine Transporter Binding With Disease Progression in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To clarify the clinical relevance of dopamine transporter single‐photon emission computed tomography (DAT‐SPECT) abnormalities in amyotrophic lateral sclerosis (ALS), with a prespecified focus on sex‐stratified associations with disease progression and short‐term prognosis.

Uniqueness of solutions to a system of differential inclusions

open access: yesElectronic Journal of Differential Equations, 2000
In this paper we study the uniqueness of solutions to the initial and Dirichlet boundary-value problem of differential inclusions $$ Delta u_i+ablacdotvec {B_i} (u_1,u_2,dots,u_N)in {partial F_i(u_i) over partial t}, quad i=1,2,dots,N, $$ where $vec{B_i}(

Similar excitability through different sodium channels and implications for the analgesic efficacy of selective drugs

open access: yeseLife
Nociceptive sensory neurons convey pain-related signals to the CNS using action potentials. Loss-of-function mutations in the voltage-gated sodium channel NaV1.7 cause insensitivity to pain (presumably by reducing nociceptor excitability) but clinical ...

Filtering Statistics on Networks

open access: yesEntropy, 2020
Compression, filtering, and cryptography, as well as the sampling of complex systems, can be seen as processing information. A large initial configuration or input space is nontrivially mapped to a smaller set of output or final states.

Subclinical Optic Nerve Involvement in Radiologically Isolated Syndrome: Multimodal Detection and Diagnostic Impact

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We aimed to determine the frequency of subclinical optic nerve (ON) lesions using MRI, optical coherence tomography (OCT), and visual evoked potentials (VEP) in radiologically isolated syndrome (RIS), and to assess their diagnostic and prognostic significance.

Benchmarking antibody discovery fidelity and reproducibility with an assay-locked residue fidelity index

open access: yesBioTechniques
Reproducibility in antibody discovery is undermined by dropout, paratope degeneracy, and immunogen imprinting. Although guidelines exist, the field lacks a shared, assay-locked metric to benchmark these liabilities across discovery pipelines.

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 ...

Heritability of types of a pregeometry relative to a family of relational structures

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
A series of geometrical and topological properties induced by structures, including degeneration, modularity, local modularity, projectivity, local finiteness, etc., play an important role in clarifying structural relationships and in classifying basic ...

Criticality and degeneracy in injury-induced changes in primary afferent excitability and the implications for neuropathic pain

open access: yeseLife, 2014
Neuropathic pain remains notoriously difficult to treat despite numerous drug targets. Here, we offer a novel explanation for this intractability.
