Synovial Osteocondromatosis in Metacarpophalengeal Joint: A Case Report

open access: yesSouthern Clinics of Istanbul Eurasia, 2017
Synovial osteochondromatosis is a benign metaplasia involving the synovial membrane, bursas, and tendon sheaths. In the literature, involvement of the hand joints is not common.

Phase locking below rate threshold in noisy model neurons [PDF]

open access: yes, 2010
The property of a neuron to phase-lock to an oscillatory stimulus before adapting its spike rate to the stimulus frequency plays an important role for the auditory system.

The influence of membrane excitations on bioethanol production in a forced fermentor

open access: yesJournal of King Saud University: Engineering Sciences, 2018
Modeling and numerical simulation are implemented to investigate the influence of membrane excitations on the production of bioethanol in a forced fermentor. Three well developed attractors in the frequency locking, quasi-periodic and chaotic regions are

Orexin enhances firing activities of neurons in neonatal rat sublaterodorsal tegmental nucleus

open access: yesDi-san junyi daxue xuebao, 2020
Objective To investigate the effect and underlying mechanism of orexin in modulating the firing activties of sublaterodorsal tegmental nucleus (SLD) neurons and its possible role in mediating rapid eye movement (REM) sleep regulation.

General Considerations Related to the Membrane Material Locking Models ‒ A Short Rewiew

open access: yesBULETINUL INSTITUTULUI POLITEHNIC DIN IAȘI. Secția Matematica. Mecanică Teoretică. Fizică, 2021
Abstract The problem of clogging membrane pores has become an area of interest for the vast majority of researchers in the field, because according to the literature, membrane materials are very sensitive when it comes to clogging and blocking pores.

Gap junctions, dendrites and resonances : a recipe for tuning network dynamics [PDF]

open access: yes, 2013
Gap junctions, also referred to as electrical synapses, are expressed along the entire central nervous system and are important in mediating various brain rhythms in both normal and pathological states.

Dynamics of subnuclear chromatin organization during "C. elegans" development : a role for H3K9 methylation [PDF]

open access: yes, 2012
In eukaryotic cells, DNA is packaged into chromatin. This imposes an accessibility barrier to all genetic processes, while at the same time offering the means for tight control.

Spike-timing dependent plasticity and feed-forward input oscillations produce precise and invariant spike phase-locking

open access: yesFrontiers in Computational Neuroscience, 2011
In the hippocampus and the neocortex, the coupling between local field potential (LFP) oscillations and the spiking of single neurons can be highly precise, across neuronal populations and cell types. Spike phase (i.e.

Mycolactone A vs. B: Multiscale Simulations Reveal the Roles of Localization and Association in Isomer-Specific Toxicity

open access: yesToxins, 2023
Mycolactone is an exotoxin produced by Mycobacterium ulcerans that causes the neglected tropical skin disease Buruli ulcer. This toxin inhibits the Sec61 translocon in the endoplasmic reticulum (ER), preventing the host cell from producing several ...

Membrane locking in the finite element computation of very thin elastic shells [PDF]

open access: yesESAIM: Mathematical Modelling and Numerical Analysis, 1998
The locking phenomenon is described in terms of lack of robustness (i.e. lack of uniformity of the finite element convergence \(h\searrow 0\) with respect to the thickness of the shell \(2\varepsilon\)). We prove that any finite element scheme consisting of piecewise polynomial functions necessarily exhibits locking for certain shells (and probably for
