Reduction in Pulse Pressure during Standing Can Distinguish Neurogenic Orthostatic Hypotension

open access: yesDiagnostics, 2021
Background: We investigated whether changes in the pulse pressure (PP) reduction ratio during the head-up tilt test (HUTT) can aid in distinguishing neurogenic orthostatic hypotension (OH) from non-neurogenic OH. Methods: We enrolled consecutive patients

The usefulness of the head-up tilt test in patients with suspected epilepsy [PDF]

open access: yesSeizure, 2014
It is estimated that approximately 20-30% of patients diagnosed with epilepsy have been misdiagnosed, and neurocardiogenic syncope (NCS) might frequently be the real cause of transient loss of consciousness (TLOC) episodes. We assessed the role of the head-up tilt test (HUTT) in patients previously diagnosed with refractory epilepsy to evaluate the ...

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

open access: yesFEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Pediatric patients’ head-up-tilt-test with pharmacological challenge, it is safe? [PDF]

open access: yesArchivos de cardiolog�a de M�xico (English ed. Internet), 2020
