High frequency of inadequate test requests for antiphospholipid antibodies in daily clinical practice [PDF]

open access: yes, 2011
Background: We have empirically noted that many physicians routinely request anti-phospholipid antibodies (aPL) without a correct clinical indication. The aim of this study was to evaluate retrospectively whether aPL testing at our Thrombosis Centre was ...

Single-Layer Sequential Rotation Network in Gap Waveguide for a Wideband Low-Profile Circularly Polarized Array Antenna

open access: yesIEEE Access, 2022
A low-profile circularly-polarized sequential rotation fed $4\times 4$ array antenna working in the Ka-band from 27.5 GHz to 31 GHz is presented. The particularity of the antenna lies in its single-layer sequential rotation feed network implemented in ...

Locking Local Oscillator Phase to the Atomic Phase via Weak Measurement [PDF]

open access: yes, 2012
We propose a new method to reduce the frequency noise of a Local Oscillator (LO) to the level of white phase noise by maintaining (not destroying by projective measurement) the coherence of the ensemble pseudo-spin of atoms over many measurement cycles ...

Acute promyelocytic leukemia (APL): remaining challenges towards a cure for all

open access: yesLeukemia and Lymphoma, 2019
The application of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO) has revolutionized the treatment of acute promyelocytic leukemia (APL). More than 80–90% of patients are expected to be cured with a combination of ATRA, ATO and/or chemotherapy.

Triple Antiphospholipid (aPL) Antibodies Positivity Is Associated With Pregnancy Complications in aPL Carriers: A Multicenter Study on 62 Pregnancies

open access: yesFrontiers in Immunology, 2019
Objective: Antiphospholipid antibodies (aPL) are risk factors for thrombosis and adverse pregnancy outcomes (APO). The management of the so called “aPL carriers” (subjects with aPL positivity without the clinical criteria manifestations of APS) is still ...

Risk-adapted treatment of acute promyelocytic leukemia: results from the International Consortium for Childhood APL.

open access: yesBlood, 2018
Pediatric acute promyelocytic leukemia (APL) can be cured with all-trans retinoic acid (ATRA) and anthracycline. However, most published trials have employed high cumulative doses of anthracyclines.

Localisation of Vertical Auditory Phantom Image with Band-limited Reductions of Vertical Interchannel Crosstalk

open access: yesApplied Sciences, 2020
Direct sound that is captured by the upper layer of a three-dimensional (3D) microphone array is typically regarded as vertical interchannel crosstalk (VIC), since it tends to produce an undesired effect of the sound source image being elevated from the ...

Anti-phospholipid-antibodies in patients with relapsing polychondritis [PDF]

open access: yes, 1998
Relapsing polychondritis (RP) is an extremly rare multisystemic disease thought to be of autoimmune origin. In order to assess if RP is associated with anti-phospholipid antibodies (aPL), clinical data and sera of 21 patients with RP were collected in a ...

Multicenter randomized trial of arsenic trioxide and Realgar‐Indigo naturalis formula in pediatric patients with acute promyelocytic leukemia: Interim results of the SCCLG‐APL clinical study

open access: yesAmerican journal of hematology/oncology, 2018
Intravenous arsenic trioxide (ATO) has been adopted as the first‐line treatment for acute promyelocytic leukemia (APL). Another arsenic compound named the Realgar‐Indigo naturalis formula (RIF), an oral traditional Chinese medicine containing As4S4, has ...
