Filter by: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 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.
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.
This is a randomized single-blind, placebo-controlled, Phase 1, single ascending dose (SAD) and repeat dose (RD), safety and tolerability study of AVB-S6-500 in healthy subjects. A SAD portion of the study consists of 4 sequential dose escalation cohorts, whereas RD portion of the study consists of a single cohort receiving 4 weekly doses of AVB-S6-500. In both SAD and RD study arms, subjects are randomized to receive either a study intervention (AVB-S6-500) or matching placebo.
Do daily high (4 tablets) or intermediate (2 tablets) administration of the broccoli-based dietary supplement Avmacol® have improved bioavailability over a broccoli sprout beverage rich in sulforaphane and its biogenic precursor, glucoraphanin? The beverage formulation has been used successfully in the investigators' previous intervention studies in regions of China with high levels of air pollution to reduce the body burden of carcinogenic and toxic pollutants. The investigators seek to evaluate a more stable, less expensive formulation of a broccoli sprout preparation that can be used for disease prevention in future studies.
The purpose of this Phase 1, randomized, open-label, two-period crossover study is to characterize and compare the pharmacokinetic (PK) profiles and evaluate the safety of the AG-348 tablet and capsule formulations after single-dose administration in healthy adult subjects. Pharmacokinetic sampling will take place serially at specified times during conduct of the study.
This is a double-blind, placebo-controlled, ascending dose, multi-cohort trial. The study will be conducted in 2 parts: a single ascending dose (SAD) part, followed by a multiple ascending dose (MAD) part. In SAD, all subjects will receive 1 dose of SPR994 (100, 300, 600 or 900 mg) or placebo, except for subjects enrolled in food effect cohorts in which subjects will receive one dose following a 10 hour fast and a second dose in the fed state following a minimum 5 days washout period. There is a single, optional, open-label control cohort that may enroll, in which all 8 subjects will receive Orapenem® (tebipenem pivoxil fine granules). In MAD, subjects will receive multiple doses of SPR994 (300 or 600 mg) or placebo for 14 consecutive days at either BID or TID dosing. In both parts, cohorts will be exposed to increasing doses of SPR994 with various extended release formulations.
