Filter by:This study will investigate the effect of caffeine and time of day on brain excitability using excitatory brain stimulation. The investigators will recruit a healthy participant and conduct a concurrent iTBS/fNIRS protocol for 20 consecutive sessions over four weeks with or without caffeine consumption before the stimulation. Moreover, the experiment will be conducted at different times of the day (morning or afternoon)
Intermittent theta-burst stimulation (iTBS) is a promising treatment for major depressive disorder. However, fewer than 50% of patients show sufficient response. Therefore, the optimal treatment protocol is worth investigating. Recent studies show that the relationship between stimulation intensity and prefrontal hemodynamic response is not linear but in an inverse U-shape by exploring the hemodynamic changes before and after iTBS. Concurrent transcranial magnetic stimulation (TMS)/functional near-infrared spectroscopy (fNIRS) setup allows the investigators to observe the prefrontal hemodynamic response during stimulation. The aim of this study is to investigate the effects of different intensities on brain activity during and after the stimulation using fNIRS.
Kinesio taping (KT) is an elastic adhesive tape with physiological effects, often used in rehabilitation and sports medicine. KT, which can stay in the body for 3 to 5 days, exerts a pulling force on the skin thanks to its wave-like structure and elasticity, and increases the gap between the subcutaneous soft tissue and fascia with its lifting effect. In this way, it reduces the superficial pressure and causes an increase in lymph circulation. In addition, with the effect it creates on the muscles, it allows maximum contraction and relaxation of the muscle and creates positive effects on the deep lymphatics. Another effective approach to increase blood circulation is exercise. Exercise, which is known to have many benefits, has been shown to increase both systemic circulation and muscle blood flow. There are findings in the literature that KT can increase the effectiveness of exercise, but it has been stated that this issue is not clear and more studies are needed. In order to evaluate the effects of KT on increasing the effectiveness of exercise and on circulation, the oxygen saturation of the muscle in the application area can be measured. As a matter of fact, "Moxy muscle oxygen monitor" has been used in the literature, which measures regional oxygen saturation (SmO2) and total hemoglobin (THb) in capillaries under the muscle. The Moxy muscle oxygen monitor is a lightweight (42 g) and small (dimensions: 61 × 44 × 21 mm) device that measures regional blood flow and oxygenation by placing it on the skin non-invasively with near-infrared spectroscopy (NIRS). Its validity in measuring muscle oxygenation was vigorous or fairly good, and its reliability was found to be moderate to high in low-intensity exercises (SROC: r = 0.842-0.993, ICC: r = 0.773-0.992, p < .01). It is thought that the application of KT, which is known to increase lymphatic and venous circulation, together with exercise will increase the amount of oxygen in the muscles. To the best of our knowledge in the literature, no study has been found in which this effect of KT is presented objectively. For this reason, it is aimed to examine muscle oxygenation with the Moxy muscle oxygen monitor, which provides objective data on KT applied with exercise.
The dual isotope method has been recently developed and used to evaluate indispensable amino acid (IAA) digestibility of various protein food such as legumes, eggs and chicken meat in healthy adults and children. The dual isotope method is an indirect method based on the measurement in plasma of absorbed IAA from a deuterium (2H) intrinsically labeled test protein compared against the same IAA of a carbon 13 (13C) intrinsically labeled standard protein of known digestibility or crystalline amino acids (AA) of theoretical 100% digestibility. However, digestibility data estimated with the dual isotope method have not been directly compared with ileal IAA digestibility directly determined through ileal digesta sampling. The goal of this study is to assess the IAA digestibility of intrinsically 2H-hen's egg in healthy volunteers using both indirect and direct methods.
Chiropractic adjustment has been shown to gap certain joints in the spine, thereby improving mobility in individuals with decreased movement capabilities. During normal motion, joints in the spine produce sounds and vibrations called crepitus. The purpose of this study is to assess how this crepitus may be used as an indicator for joint degeneration in healthy human subjects and those with low back pain, and if chiropractic adjusting causes change in this crepitus. We hypothesis that change in crepitus after adjustment may be a useful indication of changes in joint mobility and joint stiffness.
The purpose of this dietary intervention is to study the effects of several dietary fibers on the gut microbiota at the personal level. Hypothesis 1: Intake of specific dietary fibers improves the blood lipid profile depending on the personal microbiota of the participants. Hypothesis 2: detailed food intake analysis and continuous monitoring of gut microbiota enables to draw causative interrelationships between food components, bacteria of gut microbiome and health characteristics.
The purpose of the study is to evaluate the safety and tolerability of: single ascending dose (SAD) and multiple ascending dose (MAD) administration of JNJ-64457744, administered to healthy adult participants (Part 1 and Part 3), including a cohort of Asian participants (Part 1); and after single dose administration of JNJ-64457744 to chronic hepatitis B (CHB) participants who are virologically suppressed on nucleos(t)ide analog (NA) treatment (tenofovir disoproxil fumarate [TDF], tenofovir alafenamide [TAF], or entecavir [ETV]) (Part 2).
This is a randomized, double-blind, placebo-controlled phase I bridging study to evaluate the PK, PD, safety and tolerability of SR1375 in healthy subjects.
The aim of this study is to determine, quantify and understand the potential prebiotic and anti-inflammatory effects of the pecticpolysaccharide rhamnogalacturonan I (RG-I). The effects of these dietary fibre fractions on barrier function will also be investigated.
This trial is intended to examine the basic pharmacokinetics of BI 456906 and total [14C]-radioactivity, including mass balance, excretion pathways and metabolism following a single subcutaneous (SC) dose of BI 456906 (C-14) in (otherwise) healthy male volunteers with normal body weight, overweight or obesity.
