Isoprenaline versus nitroglycerine in head-up tilt test

Indian Heart Journal, 2017
Background: HUTT test is used in evaluation of syncope. Isoprenaline and isosorbide dinitrate are used to increase the sensitivity of the test. These drugs act by different mechanisms.

Heart rate recovery and diastolic blood pressure ratio on the treadmill test predict an induction and recurrence of vasovagal syncope [PDF]

The Korean Journal of Internal Medicine, 2019
Background/Aims The induction and recurrence of syncope is a concerning situation that could be unpredicted in the vasovagal syncope (VVS). We investigated a simple predictor for the induced and recurrent VVS during Head-Up table-tilt Test (HUT) and ...

Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes

FEBS Letters, EarlyView.
The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.

Signal-to-Noise Eigenmode Analysis of the Two-Year COBE Maps

, 1994
To test a theory of cosmic microwave background fluctuations, it is natural to expand an anisotropy map in an uncorrelated basis of linear combinations of pixel amplitudes --- statistically-independent for both the noise and the signal.

The anti‐CRISPR protein AcrIE8.1 inhibits the type I‐E CRISPR‐Cas system by directly binding to the Cascade subunit Cas11

FEBS Letters, EarlyView.
In this study, we present the structure of AcrIE8.1, a previously uncharacterized anti‐CRISPR protein that inhibits the type I‐E CRISPR‐Cas system. Through a combination of structural and biochemical analyses, we demonstrate that AcrIE8.1 directly binds to the Cas11 subunit of the Cascade complex to inhibit the CRISPR‐Cas system.

The role and importance of the tilt table test in pediatrics: Single-center experience and review of literature

Heart and Mind, 2020
Introduction: The head-up tilt table test is noninvasive diagnostic procedure, which is used in the diagnosis of syncope. Syncope presents a benign short-term disorder of cerebral circulation with the sudden loss of consciousness and muscle tone.

Effects of head tilt on visual field testing with a head-mounted perimeter imo. [PDF]

PLoS ONE, 2017
A newly developed head-mounted perimeter termed "imo" enables visual field (VF) testing without a fixed head position. Because the positional relationship between the subject's head and the imo is fixed, the effects of head position changes on the test ...

Repeated tilt testing in patients with tilt-positive neurally mediated syncope [PDF]

Europace, 2005
In this study we have included 222 patients with apparent neurally mediated syncope and with a positive diagnostic tilt test. The mean age was 33.4+/-21.2 years (median 25.3): there were 107 men (median age 25.3) and 115 women (median age 22.6). The age difference between males and females was statistically significant (P = 0.002).

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Tilt-Strain Changes Linked to a Jacking System Test

Civil and Environmental Engineering, 2022
A sector of the San Marco Hospital (Catania, Italy) was the subject of a jacking test in order to demonstrate the substitutability of the seismic isolator. A monitoring system, included tiltmeters and strain gauges, was applied to one column.
