Pharyngeal Stenosis and Swallowing Dysfunction Following Laryngectomy: A Scoping Review

Surgeries
Background: Pharyngeal stenosis (PS) is a common sequela of a total laryngectomy (TL), and the most common cause of postoperative dysphagia. Its exact incidence is not known.

Endoscopy in Pediatric Eosinophilic Esophagitis

Frontiers in Pediatrics, 2021
Endoscopy and mucosal biopsies are essential to the diagnosis of EoE. Together they either confirm or exclude mucosal eosinophilia and provide a visual inspection of the esophagus that may be consistent with EoE or suggest other underlying etiologies ...

Another possible interplay between gravitation and cosmology [PDF]

, 2010
I describe here some features of a non-geometrical approach to quantum gravity which leads to another picture of ties of gravitation and cosmology.

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe

Sums of Dilates

Combinatorics, Probability and Computing, 2008
The λ-dilate of a set A is λċA={λa : a∈A}. We give an asymptotically sharp lower bound on the size of sumsets of the form λ1ċA+ċċċ+λ k ċA for arbitrary integers λ1,. . .,λ k and integer sets A. We also establish an upper bound for such sums, which is similar to, but often stronger than Plünnecke's inequality.

A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.

Calculation Model of Radar Terrain Masking Based on Tensor Grid Dilation Operator

Remote Sensing
In recent years, the three-dimensional (3D) radar detection range has played an essential role in the layout of devices such as aircraft and drones. To compensate for the shortcomings of three-dimensional calculations for radar terrain masking, a new ...

Dilation and Asymmetric Relevance [PDF]

, 2019
A characterization result of dilation in terms of positive and negative association admits an extremal counterexample, which we present together with a minor repair of the result.

SPG4 and Dementia: Expanding the Clinical Spectrum

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Hereditary spastic paraplegia (HSP) is a group of disorders characterized by progressive spasticity and lower limb weakness, with mutations in SPG4/SPAST being the most common cause. Detailed studies and clinical and molecular comparisons across different populations are missing.

Cell type specificity of neurovascular coupling in cerebral cortex

eLife, 2016
Identification of the cellular players and molecular messengers that communicate neuronal activity to the vasculature driving cerebral hemodynamics is important for (1) the basic understanding of cerebrovascular regulation and (2) interpretation of ...
