Recognizing early MRI signs (or their absence) is crucial in diagnosing metachromatic leukodystrophy
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1999-2009, December 2022., 2022 Abstract Objectives Metachromatic leukodystrophy (MLD) has characteristic white matter (WM) changes on brain MRI, which often trigger biochemical and genetic confirmation of the diagnosis. In early or pre‐symptomatic disease stages, these typical MRI changes might be absent, hampering early diagnosis.

Convection in axially symmetric accretion discs with microscopic transport coefficients [PDF]
Monthly Notices of the Royal Astronomical Society, Volume 464,
Issue 1, p.410-417, 2017, 2016 The vertical structure of stationary thin accretion discs is calculated from the energy balance equation with heat generation due to microscopic ion viscosity {\eta} and electron heat conductivity {\kappa}, both depending on temperature. In the optically thin discs it is found that for the heat conductivity increasing with temperature, the vertical ...

A mathematical model for describing the retinal nerve fiber bundle trajectories in the human eye:Average course, variability, and influence of refraction, optic disc size and optic disc position [PDF]
, 2012 Previously we developed a mathematical model for describing the retinal nerve fiber bundle trajectories in the superior-temporal and inferior-temporal regions of the human retina, based on traced trajectories extracted from fundus photographs.

The anterior nucleus of the thalamus plays a role in the epileptic network
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 2010-2024, December 2022., 2022 Abstract Objectives We investigated both the metabolic differences and interictal/ictal discharges of the anterior nucleus of the thalamus (ANT) in patients with epilepsy to clarify the relationship between the ANT and the epileptic network. Methods Nineteen patients with drug‐resistant epilepsy who underwent stereoelectroencephalography were studied ...

Stability of a hot two-temperature accretion disc with advection [PDF]
, 1997 The effects of radial advection and thermal diffusion were considered in investigating the linear stability of an optically thin, two-temperature accretion disc. If the disc has only very little advection, we proved that the thermal instability exists when the disc is geometrically thin.

Review on Optic Disc Localization Techniques [PDF]
, 2017 The optic disc (OD) is one of the important part of the eye for detecting various diseases such as Diabetic Retinopathy and Glaucoma. The localization of optic disc is extremely important for determining hard exudates and lesions.

Optical coherence tomography in the evaluation of disc edema
Kerala Journal of Ophthalmology, 2019 Optic disc oedema is a common clinical problem where the ophthalmologist plays an important role in the diagnosis, management. Many optic nerve diseases can cause disc oedema like papilloedema, papillitis, anterior ischaemic optic neuropathy, central ...

On the reliability of protostellar disc mass measurements and the existence of fragmenting discs [PDF]
, 2014 We couple non-magnetic, hydrodynamical simulations of collapsing protostellar cores with radiative transfer evolutionary models to generate synthetic observations. We then use these synthetic observations to investigate the extent to which a simple method for measuring protostellar disc masses used in the literature recovers the intrinsic masses of the

Fragmentation favoured in discs around higher mass stars [PDF]
, 2020 We investigate how a protoplanetary disc's susceptibility to gravitational instabilities and fragmentation depends on the mass of its host star. We use 1D disc models in conjunction with 3D SPH simulations to determine the critical disc-to-star mass ratios at which discs become unstable against fragmentation, finding that discs become increasingly ...
