Filter by:The overall aim is to to provide a normal material for the composition and spatial heterogeneity of the following in the healthy lung: i) immune cell populations and their activation patterns, ii) the surrounding cytokine-chemokine milieu, including trans-compartmental fluxes of these mediators between the lung and bloodstream, and iii) the lung microbiome. Main hypotheses: - Absolute and relative immune cell counts in bronchoalveolar lavage fluid (BALF) are similar to those previously reported by other methods6,7. - No trans-compartmental flux of cytokines between the lungs and bloodstream is present, but cytokine concentrations (notably IL-6 and IL-8) vary with the immune-cell-microbiome composition. - Immune cell (mainly T cell) activation, differentiation, and gene expression patterns are expected to differ between blood and BALF in a manner that depends on the regional diversity of the pulmonary microbiome.
We will seek consent from participants to use the data and biospecimens collected according study protocol to address additional research questions for MGUS, SMM, MM, and other conditions. Our overarching hypothesis is that early detection of MGUS/SMM in a high- risk population, along with the comprehensive characterization of genomic/epigenomic and microenvironmental/immune regulators of disease progression will lead to strategies that intercept disease progression and improve survival.
This trial is conducted in China. The aim of the trial is to investigate safety, tolerability, pharmacokinetics and pharmacodynamics of RAY1225
The purpose of this study is to investigate the effect of moderate altitude (>1000 m.a.s.l.) on sleep examinations (polysomnography).
This is an open-label, randomized, single-dose per period, two-period, crossover study to evaluate the relative bioavailability of decitabine and tetrahydrouridine ingested as a modified-release combination formulation compared to THU and decitabine ingested as immediate-release capsules
There are times in life when people cannot use their muscles, such as during illness or injury. Muscle and mitochondria (the 'energy factory' in cells) health decline very quickly when people cannot use their muscles, but certain foods can help reduce these declines. Recent research suggests that Urolithin A, which is a natural compound that can be produced after eating pomegranates, nuts, and berries, improves muscle health. In this study, the investigators aim to investigate if a protein beverage (standard care during disuse) with or without Urolithin A can reduce or prevent the loss of muscle health while wearing a knee brace (muscle disuse).
This Study will evaluate the effects of renal function on pharmacokinetics and safety of DA-8010
The aim of this study is investigated the effect of high fat Ketogenic Diet (HFKD) in weight reduction compared to the low-fat diet (LFD) among Saudi overweight and obese women. A randomized acute controlled trial of twenty-eight healthy overweight or obese women in Saudi Arabia, aged between 18 and 40 with a body mass index between 25 and 34.5 kg m2 and fat parentage above 30% . The participants have followed ether HFKD or LFD for 12 weeks.
3,4-methylenedioxymethamphetamine (MDMA) is a psychoactive substance and prototypical empathogen acutely inducing feelings of heightened mood, empathy, trust and closeness to others. The current study investigates differences in duration of acute effects and side effects after administration of a single dose of MDMA compared to a repeated administration.
This study has two parts: Part A and Part B. The purpose of Part A of this study is to learn about the safety, tolerability, and how PF-07328948 is processed by the body when multiple doses of PF-07328948 are given to healthy participants. The purpose of Part B of this study is to understand the amount of PF-07328948 that would be available in the body after taking a single pill. The amount will be compared to the amount of PF-07328948 in a suspension in healthy adults. Part B will be conducted if the results of Part A support further study of PF-07328948. The study is seeking participants who: - are females who are not able to give birth to a child of 18 years of age or older. - are males of 18 years of age or older. - have a BMI of 20.0 to 35.0 kg/m2. - have total body weight of more than 50 kg (110 lbs). Participants in Part A will be randomly selected to receive either PF-07328948 or placebo (a pill that has no medicine in it). Participants in Part B will receive PF-07328948 as suspension and tablet form, both taken by mouth after food or during fasting. For a given participant in Part A, the total study is going to last up to about 12 weeks. This includes from the time of selection till the last follow-up phone call. The participants will be selected if they are fit for the study 28 days before the first dose of the study medicines. Participants who are selected will be admitted to the study site on Day -2 for around 19 days. Following discharge, participants will return for an on-site follow-up visit 7 to 10 days after receiving the final dose of the study medicine. The follow-up contact may be via a telephone call and will happen 28 to 35 days after the final dose of study medicine is given. For a given participant in Part B, the total study is going to last up to about 10-12 weeks. Participants will stay overnight at the CRU for 23 days (Sequence 1) or 18 days (Sequence 2), starting with check-in. In Sequence 1, there will be a minimum of 10 days between doses in Period 1 and 2, and at least 7 days between doses in Period 2 and Period 3. In Sequence 2, there will be a minimum of 7 days between each dose.
