Filter by:The purposes of this research study are to investigate closed-loop and personalized focused ultrasound as a technique to study how the brain works and to evaluate the safety and effectiveness of the Attune ATTN201 device. This study will objectively assess brain parenchyma morphology, and neuropsychiatric and neuropsychological function, following Transcranial Focused Ultrasound (tFUS) exposure. Electroencephalographic recordings during parametric sweeps will be obtained for observation of changes in the brain network activity, primarily focused on the Central Medial Thalamus (CMT). The CMT maintains strong network connectivity to the cortex and plays a potent role in sleep induction. tFUS has recently emerged as a powerful tool for targeted deep brain neuromodulation and has, in theory, the ability to modulate the activity of the CMT without affecting overlying tissue.
The most important regulatory system in the body is the autonomic nervous system. There are several studies that evaluate the effect of techniques applied at the base of the skull on the autonomic nervous system. The aim of this study is to evaluate the effect of the flying buttress technique on the autonomic nervous system.
The main purpose of this study is to conduct blood tests to measure how much LOXO-783 is in the bloodstream and how the body handles and eliminates LOXO-783 when administered alone or in combination with cholestyramine in healthy participants. The study will also evaluate the safety and tolerability of LOXO-783 with and without cholestyramine. Participation could last up to 63 days including screening period.
Neuromuscular electrical Stimulation (NMES) can minimize muscle atrophy and complications related to muscle disuse and help improve neuromuscular performance. Medium and low-frequency currents have been assessed regarding the generation of evoked torque, sensory discomfort, muscle fatigue, and peripheral oxygen extraction. In addition, metabolic stress is also linked to muscle strength gain, an important aspect to be evaluated in addition to NMES physical parameters. Thus, the aim of this study is to compare the effects of different NMES protocols applied to the triceps surae muscle for evoked torque, muscle fatigue, sensory discomfort, and peripheral oxygen extraction in healthy individuals. This is a crossover, experimental, randomized, double-blind trial composed of apparently healthy participants. All NMES protocols will be tested on the same individual with randomization of the sequence of intervention protocols. There will be a total of 5 encounters with seven days between them. Session 1 will evaluate the anthropometric measures, the maximum intensity for each intervention protocol, and the sequence of intervention protocols for each individual will be randomized. Sessions 2, 3, 4, and 5 will be composed equally with the assessment of the maximum voluntary and evoked joint torque of the triceps surae muscle through the isokinetic dynamometer, evaluation of muscle fatigue through the H-reflex, M-wave, fatigue index, time-torque-integral, and recruitment curve, evaluation of peripheral oxygen extraction through NIRS (Near Infrared Spectroscopy), electromyographic signals to assessed the RMS (root mean square) and the median frequency, evaluation of the level of sensory discomfort through the Visual Analog Pain Scale and finally by the NMES protocol. The EENM protocols will be as follows: CR10% (Russian Current at 2500 Hz, modulated in 50 Hz bursts, 200 µs and 10% duty cycle - 2 ms of 18 ms bursts and interbusrts), CA10% (Aussie Current with 1000 Hz, modulated in 50 Hz bursts, 500 µs and 10% duty cycle - 2 ms of 18 ms bursts and interbusrts), CP500 (pulsed current with 50 Hz, 500 µs phase) and CP200 (Pulsed current with 50 Hz, 200 µs phase). all protocols will be performed on the triceps surae muscle.
The Wim Hof Method is a multi-disciplinary approach to physical and mental well-being combining cold exposure, breathing exercises, and meditation. This study evaluated the effects of a 15-day WHM intervention on cardiovascular parameters at rest and during a cold pressor test, as well as on various psychological parameters.
The main aim of the study is to investigate the modulatory effects of intranasal oxytocin (24IU) on fear in naturalistic social and non-social contexts and the underlying neural mechanisms.
This is a randomized, double-blind, placebo-controlled, single ascending dose study to evaluate the safety, pharmacokinetics, and pharmacodynamics of WAL0921 in healthy subjects.
The purpose of this study is to characterize immediate changes in pain sensitivity during stretching to the point of pain, stretching in a pain free range, and a cold water immersion task. Participants will attend three sessions during which they will undergo pain sensitivity assessment and complete the assigned intervention.
The baby blues are a significant event which can occur immediately following childbirth and is a normal experience occurring in up to 76% of new mothers, characterised by mood swings, irritability, crying spells and sadness typically lasting 10-14 days. Research suggests that the more severe and longer duration of the baby blues, the higher risk of later postnatal mood disorders. Therefore, this represents a critical period which could benefit from an intervention which may prevent symptom onset or an increase in the severity of mood disorders later in the postpartum. Flavonoids are a plant bioactive found in certain fruits vegetables and beverages. Evidence suggests that consumption of flavonoid rich foods can improve physical health, mood and cognition. Prior research investigating flavonoid intervention in mothers in the first 6 months and 1 year postpartum found significant benefits to mood in the new mothers after daily flavonoid supplementation, showing promise for the management of mood in a key period for mothers, where risk of PND is high. The immediate postpartum also represents a period of cognitive changes reported to affect up to 80% of new mothers. In addition, women during this time are at an increased risk of high blood pressure and hypertension, which is thought to be a risk factor for the onset and severity of depressive symptoms and cognitive decrements. Flavonoids have been reported to improve cognition and cardiovascular health, therefore, introducing a flavonoid intervention during the immediate postpartum could have benefits to cognition and blood pressure in new mothers. The aim of the current study will be to explore whether the implementation of a high flavonoid diet across a 30-day period will positively affect maternal mental health, cognition and blood pressure. Participants will be assigned to one of three groups; high flavonoid diet, low flavonoid diet or a control condition for 30-days, starting at days 0-4 after birth. They will have visits from the researcher at 6 separate time points between the third trimester and 12 weeks postpartum. At each visit, participants will be asked to complete mood questionnaires (PANAS-NOW, EPDS, PSAS, STAI, EPDS-P) followed by a cognitive battery (MANT, Spatial n-back, RAVLT and PRMQ) and blood pressure recordings (systolic and diastolic blood pressure). Between visits, participants will be contacted by the researcher to record retrospective 24hr food recalls (Intake24).
To investigate the effect of two different dosages collagen hydrolysate (CH) on postprandial blood glucose and insulin profile in prediabetic and normo-glycaemic subjects.This will be investigated in a cross-over randomized double-blind placebo controlled study design.
