Head-up tilt test with clomipramine challenge in vasovagal syndrome—a new tilt testing protocol [PDF]

European Heart Journal, 2003
The aim of the study was to randomly compare clomipramine, used as a challenge-agent during head-up tilt test, with isoproterenol, used in the conventional test, in patients with vasovagal syndrome.The serotonergic re-uptake inhibitor clomipramine was infused (5mg in 5min) at the start of head-up tilt test (Clom-HUT) in 126 patients (mean age 41+/-16 ...

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.

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).

Inflation and Alternatives with Blue Tensor Spectra

, 2014
We study the tilt of the primordial gravitational waves spectrum. A hint of blue tilt is shown from analyzing the BICEP2 and POLARBEAR data. Motivated by this, we explore the possibilities of blue tensor spectra from the very early universe cosmology ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Carotid sinus hypersensitivity as a cause of multiple falls in an elderly patient: a case report

Revista Médica de Minas Gerais
The carotid sinus is a neurovascular structure composed of baroreceptors responsible for detecting changes in blood pressure. When the baroreflex response of the carotid sinus becomes excessively sensitive, it can result in symptoms such as syncope ...

Orientation illusions and after-effects : inhibition between channels [PDF]

, 1975
-The apparent ilt from vertical has been examined for vertical sinusoidal gratings in the presence of an inducing grating which was tilted 12 ’ from vertical. The amount of apparent tilt depended on the contrast of the test grating.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

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 ...
