Thromboelastometry (ROTEM) Assessing Hypercoagulability in Patients Referred for Thrombophilia Screening

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction Thrombophilia, a blood coagulation disorder, poses risks of venous thromboembolism (VTE). Coagulation assays may not be sufficient to assess VTE risk and global assays such as Rotational Thromboelastometry (ROTEM) may add valuable information.

Update on laboratory practice for the diagnosis of lupus anticoagulant and the antiphospholipid syndrome

Exploration of Immunology, 2023
Antiphospholipid syndrome (APS) is defined as an autoimmune and prothrombotic disorder in patients with the persistent presence of antiphospholipid antibodies (aPLs).

Activated Protein C Resistance Testing: An Update From Australasia/Asia‐Pacific

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction Activated protein C resistance (APCR) represents a risk factor for thrombosis and is usually due to factor V Leiden (FVL). Clinicians may order either test (i.e., APCR or FVL) to help assess ‘thrombophilia’ in patients who present with thrombosis. APCR testing is usually achieved using clot‐based assays, whereas FVL is assessed by

First Results from Viper: Detection of Small-Scale Anisotropy at 40 GHZ [PDF]

, 1999
Results of a search for small-scale anisotropy in the cosmic microwave background (CMB) are presented. Observations were made at the South Pole using the Viper telescope, with a .26 degree (FWHM) beam and a passband centered at 40 GHz. Anisotropy band-power measurements in bands centered at l = 108, 173, 237, 263, 422 and 589 are reported ...

Measuring Direct Oral Anticoagulant (DOAC) Levels: Applications, Limitations, and Future Directions

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction There are important challenges with the measurement and interpretation of direct oral anticoagulant (DOAC) anticoagulant effect including a lack of therapeutic ranges, inaccuracy of routinely available coagulation assays, lack of established thresholds for clinically significant effect, and uncertainty about how to apply the ...

From VIPERS to SDSS: Unveiling galaxy spectra evolution over 9 Gyr through unsupervised machine-learning [PDF]

A&A 687, A76 (2024)
Aims: This study aims to trace the chronological evolution of galaxy spectra over cosmic time. Focusing on the VIPERS dataset, we seek to understand the diverse population of galaxies within narrow redshift bins, comparing our findings with the previously mapped diversity of SDSS galaxies.

Vascular dysfunction in women with recurrent pregnancy loss: Possible association with antiphospholipid antibodies

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 206-214, April 2025.
Abstract Objective Antiphospholipid antibodies (aPL) are recognized to have a pivotal role in recurrent pregnancy loss (RPL) and cardiovascular disease. Therefore, we assessed the vascular function of women with RPL and examined the association with each type of aPL.

Vibrationally resolved electronic spectra including vibrational pre-excitation: Theory and application to VIPER spectroscopy [PDF]

, 2017
Vibrationally resolved electronic absorption spectra including the effect of vibrational pre-excitation are computed in order to interpret and predict vibronic transitions that are probed in the Vibrationally Promoted Electronic Resonance (VIPER) experiment [L. J. G. W. van Wilderen et al., Angew. Chem. Int. Ed. 53, 2667 (2014)]. To this end, we employ

Systemic lupus erythematosus‐associated autoantibodies in sickle cell disease: Spontaneous emergence in a patient and in transgenic sickle mice

British Journal of Haematology, Volume 206, Issue 4, Page 1213-1217, April 2025.
Summary We describe a patient with sickle cell disease (SCD) and elevated antiphospholipid antibodies (aPL) who developed multi‐organ failure resembling catastrophic antiphospholipid syndrome. Autoimmune screening revealed several autoantibodies characteristic of systemic lupus erythematosus (SLE). Notably, routinely housed and unmanipulated transgenic
