Dynamic Expression of the Type 1 Brugada ECG Pattern During Tilt Table Testing Using Continuous High Precordial Lead Positioning

Diagnostics
Background/Objectives: The Type 1 Brugada ECG pattern (BrP1) fluctuates according to autonomic influences. Tilt table testing induces changes in both sympathetic and parasympathetic activity. It may provide insights into the dynamic behavior of BrP1 when

Relationship between the mean platelet volume values and tilt-table test results in patients with vasovagal syncope

Medicine Science, 2018
Impaired sympathovagal balance, the main pathophysiological mechanism under the vasovagal syncope (VVS), may play a role on platelet sizes. Although it has been shown that mean platelet volume (MPV) is increased in patients with vasovagal syncope, its ...

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

Molecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Reprogramming tumor cells with LCOR mRNA nanotherapy to enhance immunotherapy

Molecular Oncology, EarlyView.
LCOR (Ligand‐dependent corepressor) mRNA encapsulated in polymeric nanoparticles restores LCOR activity in tumor cells, constraining aggressive tumor cell states and increasing tumor immunogenicity. This reprogramming makes tumor cells more vulnerable to T‐cell attack and enhances their response to immune‐checkpoint immunotherapy.

Reproducibility of tilt-table test with different dosages of sublingual nitroglycerin

, 2019
Reproducibility of tilt-table test potentiated with sublingual nitrate is significant since it is directly related to diagnostic accuracy of the test. Nitrates shorten the test time and increase the sensitivity of the test.

An outer membrane vesicle‐associated two‐track model for enterotoxigenic Bacteroides fragilis oncogenesis

Molecular Oncology, EarlyView.
Enterotoxigenic Bacteroides fragilis is a gut bacterium linked to bowel cancer. We propose that its toxin acts along two routes: at the cell surface, cutting the adhesion protein E‐cadherin and triggering inflammation; and inside the cell, delivered by bacterial vesicles, switching on NOD1 and cancer stem cell programs.

Asymptomatic Positive Tilt Test with Concurrent Atrial Fibrillation: A Diagnostic Challenge

Journal of the Practice of Cardiovascular Sciences
An elderly male was evaluated for recent-onset recurrent syncope. He has been a diabetic for the last 5 years and is on regular medications. The likely etiology of syncope was thought to be autonomic dysfunction secondary to diabetes, and hence, tilt ...

Reduced systemic vascular resistance is the underlying hemodynamic mechanism in nitrate-stimulated vasovagal syncope during head-up tilt-table test

Journal of Arrhythmia, 2015
Background: Nitroglycerin (NTG) challenge during head-up tilt-table testing (HUTT) is often utilized to determine the etiology of unexplained vascular syncope.
