The purpose of this clinical study is to demonstrate that the Parsortix™ PC1 system enables the capture and harvest of circulating tumor cells (CTCs) from the peripheral blood of patients with metastatic breast cancer (MBC) and not from healthy volunteers (HVs). The study is also designed to demonstrate that the CTCs harvested by the Parsortix PC1 system from MBC patients can be used effectively for different types of evaluations (e.g. cytopathology, FISH, qPCR, RNAseq, etc.). This is an investigational study. The Parsortix PC1 system is not FDA approved and is currently being used for research purposes only.
Japanese male healthy volunteers will receive NPF-08. The efficacy of NPF-08 will be assessed by intestinal cleaning degree. The safety of NPF-08 will be evaluated based on adverse events and adverse drug reactions observed from the date of administration to 7 days after administration.
The development of an innovative imaging agent capable of non-invasively detecting vulnerable plaques is a major objective of research in cardiovascular pathology. Such a tool would allow for better identification of patients at risk of acute events. We showed that 99mTechnetium (99mTc)-labeled fucoidan was able to target P-selectine expressed by activated platelets in vitro in humans and in vivo in a model of abdominal aortic aorta thrombus and endocarditic vegetations in rats. One of the objectives of the Nanoathero program is the clinical translation of the 99mTc-fucoidan. As a first step, we will assess the safety, biodistribution and dosimetry of this new radiopharmaceutical in humans.
The purpose of this study is to test the influences of gaze training (GT) on the acquisition of laparoscopic surgical skills. For this purpose, the investigator will compare variants of GT in the second of 2 experiments. These questions will be evaluated using the validated Fundamentals of Laparoscopic Surgery (FLS) module 1, with the overall goal of developing a surgical training curriculum that achieves expert level skill in an expedited timeframe. This research provides a novel approach to general surgery training that has the potential to reduce the amount of time and repetitions required to achieve expert laparoscopic skills.
Skin pigmentation (melanin) absorbs ultra violet type B (UVB) radiation found in sunlight and is believed to be responsible for darker-skinned persons' generally low 25(OH)D status. This phenomenon is found in immigrants living in Northern countries and their 25(OH)D responses to UVB-irradiation seem low. We hypothesized that objectively measured skin pigmentation and/or pigment genes influence UVB-induced 25(OH)D increase significantly in combination with other influential parameters. The influence of objectively measured constitutive and facultative skin pigmentation on UVB-induced 25(OH)D increase over time was investigated together with other possible influential parameters. These other influential parameters include sex, age, weight, height, BMI, number of fatty fish meals per week, Fitzpatrick Skin Type and 25(OH)D start level. The genetic parameters include 33 Vitamin D receptor and pigment SNPs. This is a single-centre, open and non-blinded clinical trial. No randomisation was used, as the participants were allocated into two groups based on their Fitzpatrick Skin type and ethnic origin. The light-skinned group included participants with Fitzpatrick Skin type II-IV and were of Northern origin (Denmark, the Faroe Islands and the UK). The darker-skinned included Fitzpatrick Skin Types V-VI originating from countries located at latitudes below 50 degrees N. Thus, it could be ensured that the participants represented a wide range of skin pigmentation. The light-skinned (N = 22) and the darker-skinned subjects (N = 18) were exposed to identical UVB doses on identical body areas over nine weeks with weekly measurements of 25(OH)D. The UVB-induced 25(OH)D synthesis was investigated in summer-pigmented skin with melanin throughout the epidermis and during winter when ambient UVB exposure is negligible. Demographic data (gender, age, weight, height, Fitzpatrick Skin Type, measured constitutive and facultative skin pigmentation (PPF)) was collected/measured and registered in prior to study start. The number of daily consumed fatty fish meals was recorded in a questionnaire. Serum 25(OH)D was analysed weekly.
The planned study is to determine the pharmacokinetic properties of Esketamine and safety assessment with inhaled Esketamine after different number of inhalations and different dosing sequences within three parts of the study.
Background: Artificial sweeteners like sucralose are found in many foods and drinks. Sucralose might affect hormones and cause health changes. Objective: To see if sucralose changes how medicines are absorbed and processed, how hormones are secreted, gut bacteria, and how fat cells are metabolized. Eligibility: People ages 18-60 who: - Are black or Hispanic - Weigh more than 110 pounds - Have a body mass index of 25-40 - Do not have a condition that requires drug treatment Design: Participants will be screened with: - Medical history - Physical exam - Blood, heart, and urine tests Participants must not eat or drink anything with artificial sweeteners throughout the study. Over 7 days, Participants will answer questions, and give daily urine samples and 1 stool sample. Participants will repeat these throughout the study. Overnight Visit 1: participants will fast starting the night before. They will get breakfast at the visit. The visit includes: - An IV will be placed in the arm. Participants will get 2 tablets of medicines. Blood will be drawn several times over 24 hours. - A piece of fat tissue may be taken from the abdomen (biopsy). - Participants will have a sweet drink. Blood samples will be taken over 2 hours. Then participants will be randomly assigned to take either a sucralose capsule or placebo. They will take it twice a day for 2 weeks. They will complete two 24-hour food diaries. Overnight Visit 2 repeats Visit 1 except the biopsy. Then participants will take the capsules for another 2 weeks. Overnight Visit 3 repeats Visit 1. Participants may be contacted by phone within 4 weeks after they finish.
The investigator showed that a night of sleep deprivation halved the duration of an inspiratory endurance test and that this loss of endurance could be secondary to a lack of activation of the pre-motor cortex. However, the inspiratory endurance test is associated with a feeling of dyspnea that could lead to premature arrest, and the inspiratory drive is complex, both automatic and voluntary. The investigator can reproduce this results on a simpler drive. During the execution of an exercise involving repeated contractions of the hand it is possible to record the activation of the pre-motor cortex corresponding to the phase of preparation of the movement. The amplitude of these premotor potentials is proportional to the developed motive force. The purpose of this study is to assess the impact of sleep deprivation on the muscular endurance of non-dominant in healthy subjects. Hypothesis: Sleep deprivation causes a decrease in manual motor endurance by decreasing cortical pre-motor control. Main objective: To compare the motor endurance of healthy subjects after a night's sleep and after a sleepless night. Secondary objective: To compare the amplitude of premature cortical control at the beginning of the endurance test after a night's sleep and after a sleepless night.
The purpose of this study is to evaluate the pharmacokinetics (PK), safety and tolerability and pharmacodynamics (PD) of lanadelumab in healthy adult Japanese subjects and matched non-Hispanic healthy adult Caucasian subjects.
