Increasing time interval and decreasing allergen dose interval improves ex vivo desensitization of human blood basophils KU Leuven Vrije Universiteit Brussel
BACKGROUND: Desensitization is a method for inducing temporary tolerance to allergen. The mechanism underlying desensitization is yet to be established. METHODS: Basophil granulocytes in whole blood from grass pollen allergic subjects were desensitized ex vivo by sequential addition of increasing allergen concentrations. At each step basophil activation (CD193 + CD63+ ) was monitored with and without (background activation) allergen challenge at ...
Does the time interval between antimüllerian hormone serum sampling and initiation of ovarian stimulation affects its predictive ability in in vitro fertilization-intracytoplasmic sperm injection cycles with a gonadotropin-releasing hormone antagonist? A Vrije Universiteit Brussel
Objective
To investigate whether the time interval between serum antimüllerian hormone (AMH) sampling and initiation of ovarian stimulation for in vitro fertilization-intracytoplasmic sperm injection (IVF-ICSI) may affect the predictive ability of the marker for low and excessive ovarian response.
Design
Retrospective cohort study.
Setting
University-based tertiary center.
Patient(s) ...

Validation and reference interval of activated clotting time in dogs using a point-of-care analyzer Universiteit Gent
BACKGROUND Activated clotting times (ACT) are measured to titrate anticoagulant dose during intravascular procedures. Point-of-care (POC) analyzers could improve test practicality and accuracy compared to manual tests, but a reference interval (RI) for dogs is lacking. OBJECTIVES To establish a RI for ACT in adult dogs using a POC analyzer, to quantify longitudinal intra-subject variability and to investigate device reliability and inter-device ...
Methylphenidate, interstimulus interval, and reaction time performance of children with attention deficit/hyperactivity disorder : a pilot study Universiteit Gent
Thirteen children with attention deficit/hyperactivity disorder (ADHD: DSM-IV-TR) participated in the pilot study. They carried out a Go/No-Go test with a short (2 seconds) and long (6 seconds) interstimulus interval (ISI) when on placebo and a therapeutic dose of methylphenidate (MPH). For the long-ISI placebo condition the responses were slow and inaccurate. This pattern of response may be due to underactivation of the readiness-to-respond ...
Expanding the time interval between ovulation triggering and oocyte injection Vrije Universiteit Brussel
STUDY QUESTION: Is the time interval between ovulation triggering and oocyte denudation/injection associated with embryological and clinical outcome after ICSI?
SUMMARY ANSWER: Expanding the time interval between ovulation triggering and oocyte denudation/injection is not associated with any clinically relevant impact on embryological or clinical outcome.
WHAT IS KNOWN ALREADY: The optimal time interval between ovulation ...
Time interval between maternal electrocardiogram and venous Doppler waves in normal pregnancy and preeclampsia: a pilot study. Universiteit Hasselt
Purpose: To evaluate the time interval between maternal electrocardiogram (ECG) and venous Doppler waves at different stages of uncomplicated pregnancy (UP) and in preeclampsia (PE). Materials and Methods: Cross-sectional pilot study in 40 uncomplicated singleton pregnancies, categorized in four groups of ten according to gestational age: 10 – 14 weeks (UP1), 18 – 23 weeks (UP2), 28 – 33 weeks (UP3) and ≥ 37 weeks (UP4) of gestation. A fifth ...
Climate warming shifts the time interval between flowering and leaf unfolding depending on the warming period Universiteit Antwerpen
The timing of flowering (FL) and leaf unfolding (LU) determine plants' reproduction and vegetative growth. Global warming has substantially advanced FL and LU of temperate and boreal plants, but their responses to warming differ, which may influence the time interval between FL and LU ( increment LU-FL), thereby impacting plant fitness and intraspecific physiological processes. Based on twigs collected from two flowering-first tree species, ...
Time-measured phylogenies of gag, pol and env sequence data reveal the direction and time interval of HIV-1 transmission KU Leuven
OBJECTIVE: To investigate whether time-measured phylogenetic analysis of longitudinal viral sequences can establish the direction and timing of HIV-1 transmission in an epidemiologically linked transmission cluster of three homosexual men. DESIGN: An HIV-1-infected homosexual man (patient 1) and his long-term HIV-negative partner (patient 2) engaged in a triangular relationship with an additional partner (patient 3). On the basis of phylogenetic ...
Impact of vascular calcification on corrected QT interval at the time of renal transplantation KU Leuven
Sudden death is the major cause of cardiac mortality in dialysis patients, accounting for approximately 60% of cardiovascular deaths. A prolonged QT interval and arterial calcification have been associated with increased cardiovascular morbidity and mortality in different patient populations including patients with chronic kidney disease (CKD). In the present study, we aimed to elucidate the association of vascular calcification with corrected ...
