In and ex Vivo Mitochondrial Function of the Heart

It has been suggested that mitochondrial dysfunction might play a role in the development of diabetic cardiomyopathy. From animal studies, it has been suggested that an altered PPAR and PGC1 expression is involved in the reduced cardiac mitochondrial function, however human data on cardiac mitochondrial function and PPAR regulation is scarce. The latter is due to the fact that there is no validated measurement for assessing cardiac mitochondrial function non-invasively in vivo....

In-Vivo Bleeding Volume Test for Platelet-Aspirin Interaction

Determination of a Dose-dependent Effect of GOS on Iron Absorption, and Addition of Vitamin C

Iron deficiency is still the most common and widespread nutritional disorder in the world according to WHO. In a recent iron absorption study in adult women with low iron stores in our lab (publication under review), we found that 15 g of GOS given with an iron supplement in the form of iron fumarate acutely increased iron absorption when given with water and a bread based meal. The dose of 15 g of GOS was tolerated well by the participants. As a follow up to the study m...

B-cryptoxanthin and Phytosterols on Bone Remodeling and Cardiovascular Risk Factors

We, the investigators, aim to study, in vitro and in vivo, the bioavailability of added b-cryptoxanthin and phytosterols and evaluate in vivo its effect on biochemical markers of bone remodelling and cardiovascular risk. Specifically, we will 1) assess the stability in the food and the bioavailability of b-cryptoxanthin in the presence of phytosterols (absorption modifiers) by using a complementary approach; in vitro and in vivo studies; and 2) we will study in post-menopausal ...

Ex Vivo Pilot Study of the Impact of Nasal Breathing During the Administration of Inhaled Corticosteroids by Inhalation Chamber in Asthmatic Children Ages Between 1 and 4-year-old

Nasal Administration of Sufentanil+Ketamine for Procedure-related Pain in Children

The aim of the study is to test the absorption and clinical effect of nasal administration of sufentanil+ketamine (nasal spray) for procedure-related pain in hospitalized children.

Bone Substitute in the Multi Traumatized Nasal Septum Reconstruction

The aim of this project is to evaluate the safety and efficacy of the biomaterial made of HAP/TCP (BCP, Kasios®), in septoplasties of multi traumatized human nose. The use of this biomaterial will avoid the graft sampling and we expect it to be a good substitute to support the nasal pyramid while favouring the respiratory epithelium regeneration. Thus, that would confirm previous in vitro and in vivo studies.

The Effect of 'Sniffing Position & Nasal Tip Lifting' in Nasotracheal Intubation

The goal of this prospective randomized study is to compare the effect of nasal tip lifting during nasotracheal intubation. The question the investigators are trying to answer is: If the nasal tip is tilted, will the E-tube be more likely to enter the lower passage during nasal intubation?

The intent of this study is to see if the rate that the body breaks down l-methamphetamine (l-MA) could be used as an accurate estimate for the rate that the body breaks down d-methamphetamine (d-MA). l-MA is sold over the counter as a nasal decongestant where as d-MA is the commonly abused form of methamphetamine.

Iron Long-Term Labelling Study Malawi

Conventional indirect indicators of iron status, using serum and red blood cell biomarkers, are confounded by inflammation from common infections in sub-Saharan Africa, a region with a high prevalence of iron deficiency, making the assessment of iron balance and efficiency of iron intervention difficult. A new method allowing accurate measurement of long-term oral iron absorption and allowing the estimation of iron requirements is highly needed. Such a novel method to quantify ...
