The research aims to determine the parameters of oxidative stress and inflammatory processes and compare these parameters with the image obtained using positron emission tomography (PET) with 2-deoxy-2-[fluorine-18]fluoro- D-glucose (18F-FDG) integrated with computed tomography (CT) in the group of oncological patients.
The effects of a nutraceutical combination (NC) containing low-dose monacolin K and berberine on lipid profile, proprotein convertase subtilisin/kexin type 9 (PCSK9), subclinical inflammation and arterial stiffness were investigated in human immunodeficiency virus (HIV)-infected patients receiving stable antiretroviral therapy (ART).
This study evaluates the effect of balanced and sustainable diet application on fat composition, insulin resistance and inflammation marker in obese people. Intervention: Obese subject will receive intervention on balanced and sustainable diet application Control: Obese subject will receive a balanced diet application only
This study uses an experimental design to conduct a double-blind, randomized, crossover study where participants receive both diesel exhaust and a mental stress test in a controlled setting. My hypothesis is that the synergistic effect of stress and air pollution will result in higher levels of stress and inflammation (measured via biological markers) as well as poorer cardiovascular disease related outcomes compared to the independent effect of each exposure separately.
Demonstrate the ability of subjects suffering from sinus pain to self-treat with the SYNUS Pain Relief device and to obtain pain relief compared to a sham/placebo device.
The primary objective of this clinical trial is to evaluate the safety of autologous engineered corpora cavernosa + albuginea constructs for treatment of complex penile deformities. Autologous endothelial and smooth muscle cells obtained from enrolled subjects' corpora cavernosa biopsy sample, will be culture expanded in vitro and used to seed decellularized corpora cavernosa + albuginea obtained from cadaveric-donors to create autologous bioengineered corpora cavernosa/albuginea constructs for repair of damaged penile tissues.
Open heart surgery requires the use of a cardiopulmonary bypass (CPB) circuit. As blood flows across the artificial surfaces of the CPB circuit, platelets are activated and consumed. This activation results in a profound inflammatory reaction and need for transfusion. This reaction is intensified in younger, smaller patients undergoing longer, more complex open heart surgery. Nitric oxide is naturally released by vascular endothelial surfaces and acts as a signaling molecule which prevents platelet activation. The investigators hypothesize that the addition of the nitric oxide to the sweep gas of the oxygenator during cardiopulmonary bypass surgery will replace this natural endothelial function and thus prevent platelet activation and consumption. The investigators plan to test this hypothesis with a pilot double blinded, randomized trial of 40 patients less than a year of age undergoing cardiac surgery requiring CPB.
Effects of acute intermittent hypoxia on brain function imaging and systemic inflammation Patients with obstructive sleep apnea (OSAS) may have neurological cognitive impairment. The reason is not clear. Intermittent hypoxia is one of the main manifestations of OSAS. The investigators hypothesize that acute intermittent hypoxia (AIH) can lead to abnormal metabolic activity in some regions of the brain, which may be associated with systemic inflammation. The investigators proposed in 12 to 15 cases of healthy volunteers, in the form of breathing in the nitrogen intermittently, were observed before and after AIH MRI diffusion tensor imaging (DTI) changes in brain regions and at the same time understand the inflammatory factors and the change of oxidative stress in the human body. The investigators look at the data from different brain regions of the brain DTI anisotropic score (FA), radial diffusion coefficient (RD), axial diffusion coefficient (AD) and peripheral blood interleukin-6 (IL - 6), interleukin-8 (IL - 8), interleukin-10(IL - 10), tumor necrosis factor alpha (TNF-α), Interleukin-1 beta (IL-1β), Leptin, high sensitivity reactive protein(hsCRP), Intercellular Adhesion Molecule 1(ICAM 1),Vascular cell adhesion protein 1(VCAM-1) , E-selectin, endothelin-1(ET - 1), 8-iso-PGF2α,3-nitrotyrosine(3-NT),hypoxia-inducible factor 1α(HIF 1α). Statistical data processing includes: the matching t test of the above indicators before and after AIH; The relationship between DTI and peripheral blood inflammatory factors was analyzed by single factor. Using DTI as the dependent variable, the peripheral blood inflammatory factor was analyzed by multifactor correlation. Ultimately, the effect of AIH on the brain's regional functions will be understood, and whether the effect is related to systemic inflammation.
The study will examine the use and impact of a meditation app delivered to adult workforce populations facing extreme time demands. Enrollees will be randomized to either app or a wait-list group, and will be assessed in terms of job and daily functioning, well-being, and biomarkers of immune function and stress physiology, and neural structure and function prior to randomization and again at multiple time points after participants commence app engagement. In order to assess efficacy, we will examine the longitudinal changes in all measures in both the mindfulness group, compared to wait-list control group.
This pilot study will examine the benefit of this amino acid based hydration solution in patients with IBD who have undergone a total colectomy and have either ileostomies or jpouches. Findings from this study and possible future studies could have broad implications for patients with malabsorption resulting from many underlying conditions, including IBD.
