Levodopa-induced dyskinesia severely limits the use of levodopa in Parkinson's disease and constitutes a debilitating complication of dopaminergic treatment in late stage. Among several neurobiological mechanisms identified so far, the investigators have established in experimental models the key role of D1 receptor hypersensitivity and a"Ras-ERK" signalling pathway. As the very same dopamine receptor machinery and the Ras-ERK pathway are present in blood lymphocytes, the inves...
The purpose of this study is to investigate the influence of difference positioning on extension and efficacy of brachial plexus anesthesia at 20 minutes by using the axillary plexus block with supine positioning and a lateral positioning onto the non-anaesthetized side, combined with 20° Trendelenburg positioning.
Knowing the dramatic increase in thrombin generation during sepsis, our research hypothesis is that AMPK-induced ACC phosphorylation in platelets is increased and that this might modulate platelets metabolism and more particularly platelets inflammatory mediators content, coming from AA and lipids.
Fetuin-A has been identified as a novel physiological regulator of insulin action in vitro, in intact cells and in vivo in animals. Previous research has shown that circulating levels of fetuin-A were increased in animal models of insulin resistance and diabetes. Additionally, several human investigation studies demonstrate a correlation of fetuin-A levels with body mass index, insulin resistance, and a fatty liver. Recently, the investigators have elucidated the role of fetuin...
Fragile X Syndrome (FXS) is caused by loss of FMR1 expression on the X chromosome that leads to increased mRNA translation, which results in hyperactivation of ERK (extracellular signal-regulated kinase) and mTORC1 (mechanistic target of rafampicin complex 1) signaling and consequently in synaptic dysfunction and neurological development. There is presently no cure for FXS. Recent studies suggest that metformin (a widely prescribed drug for type II diabetes in children and adul...
Patient positioning is an essential part of a preventive strategy for neurocritical care patients. The aim of the study will be to determine whether the positioning of the bed is the same or better compared to the positioning of the patient's bed in the presence of pressure ulcer.
Primary: - To assess the safety and tolerability and to find the maximum tolerated dose of the combination administration of RAD001 plus docetaxel when given to patients with metastatic breast cancer who are being considered for standard docetaxel treatment (phase I). - To characterize the pharmacokinetics of RAD001 and docetaxel when co-administered (phase I). Secondary: - To assess the clinical efficacy of the combination reg...
Rational of the study: There are arguments to think that the closure of macular holes can be obtained without a strict positioning under certain conditions, i.e. hole size ≤ 400 µm, if the patient avoids the position laid down on the back. In order to be able to confirm these observations, it is necessary to make a randomized study with an adequate number of patients. Aim of the study: To show that the percentage of success (anatomical closure confirmed by OCT) is not...
The purpose of this trial is to test the hypothesis that at the end of 28 days, infants and children with acute lung injury treated with prone positioning would have more ventilator-free days than those treated with supine positioning.
The macular hole formation takes place in the centre of the retina. A closure of the macular hole is believed to take place if the central retinal area is kept dry in the postoperative period. Therefore the eye is filled with a gas mix and the patients are urged to avoid the supine position in the first postoperative days. The investigators have developed a positioning measuring device which can measure the extent of supine positioning time. Patients are to carry the positionin...
Randomized clinical study in order to evaluate the accuracy of pedicle screw positioning during spine surgery performed with MySpine patient match positioning guide or Free hand technique.
Recent studies have shown that dysregulation of ANXA1 expression are associated with tumorigenesis. Overexpression of ANXA1 protein is found in a wide variety of human tumors, such as breast 10, liver 11, pancreatic cancer14 and glial tumors15. In contrast, reduced levels of ANXA1 protein expression have been reported in ESCC4, 5, gastric6, breast7, head and neck SCC8 and prostate cancer9. No previous study on ANXA1 protein expression has been reported in the cancer of oral ...
Prone positioning has been shown to improve survival in patients with acute respiratory distress syndrome (ARDS). However, a recent large observational study found that prone positioning was used in only 7% of all ARDS patients, and 16% in the severe category. However, this study did not focus on the prone position per se. In present study, the investigators would like to explore the rate of use of prone positioning in ARDS patients and the reasons why this treatment was not ap...
Femtosecond laser-assisted cataract surgery consists in nuclear lens fragmentation, followed by ultrasound phacoemulsification of nuclear lens, which is then removed. It can be assumed that fragmenting the nuclear lens in more pieces could facilitate the post-laser ultrasound phacoemulsification to extract the lens, with a lesser amount of ultrasonic energy. The decrease of ultrasonic energy delivered during cataract surgery is beneficial to the patient because it optim...
Normal cells primarily produce energy with the help of the "mitochondria". These "small organs" are also called the "powerhouses of the cell" turn the sugars, fats and proteins that we eat into forms of chemical energy that the body can use to carry on living. This process is called oxidative phosphorylation. In addition to the help from the mitochondria and oxidative phosphorylation, most cells can produce energy by lactic acid fermentation. This process is less energy efficie...
Objectives: Primary endpoint: -Assess the clinical activity of RAD 001 plus depot octreotide as defined by progression free survival duration defined by RECIST criteria in treated and untreated patients with metastatic, unresectable low grade neuroendocrine carcinoma. Secondary endpoints: - Assess the progression free survival duration of patients with metastatic, unresectable low grade neuroendocrine carcinoma treated with RAD 001 plus depot octreotide....
We are proposing a clinical investigation of the pathogenesis of insulin resistance (IR) in skeletal muscle and adipose tissue (AT), focusing specifically on the contributions of glucose delivery, transport and phosphorylation. The primary methodology will be dynamic PET imaging, using three tracers that respectively portray the kinetics of glucose delivery, bi-directional trans-membrane glucose transport and glucose phosphorylation. The three tracers are: 1) [15O]-H2O for quan...

Northwell Health Visits (NHV) is a three year pilot replication of the evidence-based model, Family Connects, which is a brief universal Nurse Practitioner home visiting program for new mothers and their infants. We seek to compare outcomes among mothers and infants enrolled in the NHV enhanced intervention arm, those enrolled in the NHV screening-only arm, and those in the control arm. NHV will follow a three- armed randomized control trial design.
The purpose of this study is to analyze the findings of 30 surgeons and 30 nuclear radiologists of 61 individual thyroid scans. The goal is to determine if surgeons are more prone to making a definitive diagnosis based on a given scan than a nuclear radiologist. Accuracy of localization of the two groups will be analyzed. A secure website has been designed to which the physician will be able to login and view and rate the quality of each image and make a localizing diagnosis....
The mechanisms behind heart failure are largely unknown. Despite an increasing arsenal of pharmacological therapies, cardiovascular disease is still the most common cause of death in the western world, which demonstrates a pronounced need for more patient-related mechanistic research. Cachexia and limited exercise capacity are the symptoms that best match prediction of heart failure, both of which are symptoms involving a dysfunctional skeletal muscle. An increased understandin...
This is a prospective, randomized study of total hip arthroplasty with and without the use of Radlink surgical positioning software. The investigators are interested in discovering whether the use of the Radlink software will provide more accurate acetabular cup position when compared with surgeon estimates based on visual inspection of fluoroscopic images.
