NLRC4, an inflammasome , is a cytosolic multiprotein complex involved in the initiation and modulation of the immune response. Periodontitis is a chronic inflammatory disease that can start with localized inflammatory reactions created by the supporting tissues surrounding the teeth against microorganisms and then result in loss of teeth. It has been said that proinflammatory cytokines released in the microenvironment of periodontitis can increase the expression of NLRC4 inflammasome genes. The authors think that NLRC4 may play a role in the periodontitis. The aim of this study is to compare the NLRC4, IL-1β and IL-10 levels of healthy and periodontitis individuals.
Background: Muscular strength training interventions have long been a cornerstone in the prevention, non-surgical management and rehabilitation of the entire spectrum of musculoskeletal injuries and diseases. The key goal of strength training, especially during rehabilitation, is to regain healthy musculoskeletal function. Yet, there remains a fundamental lack of understanding with regards to the relationship between subject-specific musculoskeletal biomechanics (i.e. multi-body dynamics function) and different types of strength training interventions because of limitations in assessing these parameters outside the research setting. Thus, clinicians, physiotherapists and coaches continue making training recommendations based on subjective and generalised guidelines, with ineffective or possibly harmful consequences for individual patients and athletes. Goal: This project aims to advance strength training guidelines and monitoring of training safety and efficiency by means of subject-specific anatomically-based modelling, biomechanical analysis of musculoskeletal function and mobile monitoring of training volume and muscular fatigue in the athletic and recreational setting. Method: For validation purposes, the investigators will conduct an 8-week intervention study in healthy volunteers with three levels of strength training volume of the key muscle-tendon groups associated with knee joint stability and relate the changes in musculoskeletal and biomechanical parameters to the training-specific parameters and muscular fatigue from mobile monitoring through correlation analysis. Relevance: In Switzerland, more than 1.3 Mio people are members of a fitness center. Strength training is not only a cornerstone in the maintenance of fitness and rehabilitation from musculoskeletal injuries and diseases as the most frequently reported health issues.
Mescaline (the active substance in Peyote and San Pedro cacti) is a classic and long known serotonergic psychedelic substance (hallucinogen) that is widely used for recreational, spiritual, and/or ethno medical purposes. Despite its long history, modern data on the acute effects of mescaline on human is lacking. Mescaline produces prototypical psychedelic effects, similar as lysergic acid diethylamide (LSD) and psilocybin. The serotonin 2A (5-HT2A) receptor is thought to primarily mediate acute alterations of consciousness induced by LSD and psilocybin. However, the contributory role of the 5-HT2A receptor in mescaline-induced alterations of consciousness is unclear. Using 5-HT2A receptor antagonist ketanserin, the psychedelic experience induced by LSD and psilocybin can be attenuated and shortened. The present study therefore explores the role the 5-HT2A receptor in mescaline-induced altered states of consciousness using escalating doses of mescaline and the 5-HT2A receptor blocker ketanserin administered before a high dose of mescaline. Objective: The present MDR-study will characterize the subjective effects of different doses of mescaline using modern psychometric instruments and examine the contribution of the 5-HT2A receptor in the mescaline-induced alterations of consciousness. Design: Double-blind, placebo-controlled, 6-period cross-over design with six treatment conditions. 1) Placebo (Pla + Pla), 2) 100 mg mescaline (Pla + 100mg mescaline), 3) 200 mg mescaline (Pla + 200mg mescaline), 4) 400 mg mescaline (Pla + 400mg mescaline), 5) 800 mg mescaline (Pla + 800mg mescaline), and 6) 40mg ketanserin and 800mg mescaline (Ket + 800mg mescaline). Participants: 16 healthy participants aged ≥ 25 and ≤ 65 years (8 female, 8 male)
The purpose of this study is to evaluate the safety and tolerability of single and multiple doses of nipocalimab following subcutaneous (SC) administration compared with intravenous (IV) administration in healthy participants.
The main purpose of this study is to evaluate two different devices that may be used to inject medication just under the skin. Participants will receive placebo; no active drug will be given. The study will last up to five weeks for each participant, including a one-week overnight stay in the study center.
The serotonin (5-HT) and oxytocin releaser and so-called "empathogen" 3,4-methylenedioxymethamphetamine (MDMA) acutely produces positive feelings, empathy, and trust. MDMA is used recreationally (ecstasy), as research tool to study 5-HT and oxytocin function, and is investigated for MDMA-assisted psychotherapy. MDMA is metabolized in part (10%) to the psychoactive metabolite 3,4-methylenedioxyamphetamine (MDA) which itself is also a recreational substance and has also been used to assist psychotherapy in the past. The present study aims to describe and directly compare for the first time the effects of MDMA and MDA in the same healthy volunteers and using modern psychological and psychometric tests. Additionally, although amphetamines including MDMA and MDA induce mainly positive subjective effects they may also produce negative subjective drug effects including anxiety in particular at the onset of the subjective response and the rapid onset of euphoria may increase the risk of abuse. Additionally, blood pressure may increase rapidly at drug onset. A possible solution to mitigate anxiety, abuse-related rapid euphoria increases and/or rapid blood pressure changes at onset consist of slowing the onset of the drug effect by using a slow-release formulation of MDMA. In the present study, the investigators will characterize the effects of lysine-MDMA and lysine-MDA and compare their effects with MDMA/MDA to test the concept of attenuated effects across both substances.
The ExpoBiome project will analyze the impact of fasting on patients with Parkinsons's Disease (PD) or rheumatoid arthritis (RA) on a clinical level as well as the effect of fasting on their immune system and gut microbiota. ExpoBiome will combine metagenomics and other "omics" [meta-transcriptomics, meta-proteomics and (meta-)metabolomics], bioinformatic analyses and biostatistics under a systems biology framework to gain new mechanistic insights into microbiome-immune system interactions in the context of chronic diseases with inflammatory signatures. Besides a one time crossectional study of healthy participants, patients with RA and PD a longitudinal fasting study with two arms (RA and PD) is planned.
The purpose of this study is to evaluate the safety and tolerability of JNJ-68179280 compared with placebo after administration of single ascending oral doses of JNJ-68179280 administered to healthy participants (Part 1), multiple ascending oral doses of JNJ-68179280, administered to healthy participants once daily (Cohorts 1 through 4) or twice daily (Cohort 5) over 14 consecutive days (Part 2) and multiple ascending oral doses of an alternative JNJ-68179280 formulation, administered to healthy participants once daily over 14 consecutive days (Part 3 if conducted).
The purpose of this study is to evaluate the relative bioavailability and food effect of a single dose of milvexian administered as direct compression (DC) oral tablets and roller compacted (RC) oral tablets compared with milvexian administered as Phase 2 oral capsules (Part 1) and of new concept tablets consisting of a single dose of milvexian administered as oral Tablet 1 and Tablet 2 compared with milvexian administered as Phase 2 oral capsules (Part 3) in healthy participants under fasting and fed conditions; to characterize the pharmacokinetics (PK) of multiple twice daily (BID) doses for 5 days of milvexian administered as DC oral tablets and Phase 2 oral capsules in healthy participants (Part 2) and to assess the effects of dosing time and food timing on the PK of single-dose of milvexian Phase 3 oral tablet formulation in healthy participants (Part 4).
