Filter by:A Prospective, randomized, double-blinded, placebo-controlled trial will be conducted at the pediatric dialysis unit, Children's Hospital, Ain Shams University in order to investigate the benefits of melatonin supplementation on oxidative stress, inflammation and to assess sleep quality by using PSQI questionnaire in pediatric hemodialysis patients.
Depending on the anesthesiologist's habits, injection or not of a 1.5 mg/kg bolus of lidocaine at induction of anesthesia followed by a continuous infusion of 1.5 mg/kg/h. Additional blood sample at 3 different times without additional puncture compared to usual management: 1) during the placement of the venous line before induction (Reactive Oxygen Species), 2) 1h after the end of induction at the time of blood gas to adapt ventilation (Reactive Oxygen Species), 3) at 24h of the beginning of the intervention (Reactive Oxygen Species and antioxidant molecular profile).
The subject of doctoral dissertation: Assessment of the effects of a meatless, ketogenic restrictive diet on body composition, strength capacity, oxidative stress and immune response During planning of research and topic of the doctoral dissertation, it was considered how to modify a standard ketogenic diet rich in saturated fatty acids so that the use of this model of nutrition has the most anti-inflammatory effect. Therefore, it was decided to conduct a research to check whether a diet rich in omega-3 polyunsaturated fatty acids will show such an effect when following a high-fat diet. Hypotheses: 1. The ketogenic diet reduces systemic inflammation. 2.The ketogenic diet reduces oxidative stress. 3. The ketogenic diet reduces body fat. 4. A ketogenic diet does not worsen strength performance.
This study aims to obtain data on the potential influence of Vine to Bar product(s) containing Chardonnay marc on cardiometabolic health. These initial studies will inform the design and timing of data collection for future dietary intervention trials that will examine the influence of Chardonnay marc intake on outcomes/biomarkers of both cardiometabolic health and the gut microbiome. This includes collecting data on the potential differences in response to the products based on the unique food matrix for each of the products that will be tested. Moreover, as there is a paucity of data on the influence of cocoa flavanol intake on vascular function beyond 4 hours post intake, the response of the selected outcomes will be assessed after 6 hours of flavanol intake. This is a time point that captures the increased circulating presence of microbial derived flavanol metabolites.
Vitamin D deficiency is now considered a global problem in general population, but it seemed to be more prominent in chronic kidney disease (CKD) patients, especially those on regular hemodialysis. Being a key regulator in mineral metabolism, there's also emerging evidences linking vitamin D deficiency with inflammation and oxidative stress, which are both recognized as constant threats to cardiovascular outcomes in hemodialysis patients. It's prospective, randomized trial that's carried out to evaluate the effect of weekly versus, monthly oral cholecalciferol, on vitamin D (25(OH)D) levels, oxidative stress markers, inflammatory markers and secondary hyperparathyroidism in hemodialysis patients. Fifty eligible hemodialysis patients were randomly assigned to either Group A (Oral 50.000IU Cholecalciferol, once weekly) or Group B (Oral 200.000IU Cholecalciferol, once monthly), for 3 months. Serum levels of (25(OH)D), serum malondialdehyde (MDA), serum superoxide dismutase (SOD), serum high sensitive (hsCRP), calcium, phosphorus, and intact parathormone (iPTH) levels, were all assessed at baseline and at the end of the study
Primary Ovarian Insufficiency (POI) is dysfunction of ovaries before 40 years of age. It has been reported that genetic factors, endocrine disorders, previous pelvic surgeries, chemotherapy and radiotherapy, and autoimmune mechanisms play a role in 10%, however the etiology has not been clarified in 90% of the cases. Oxidative stress and autoimmunity has been shown to be responsible in the etiopathogenesis of POI. Prolidase is an imidodipeptidase. Prolidase was shown to be related with oxidative stress and autoimmune diseases in previous studies. In addition, it is thought that the level of prolidase plays a role both in the etiopathogenesis and progression of diseases. This study aims to investigate the level of prolidase enzyme in women with POI.
Recent research evidence suggests that cottonseed oil (CSO) may have both direct and indirect anti-inflammatory and anti-oxidative impacts linked to bioactive components of CSO and favorable alterations in lipid metabolism. These impacts are directly related to non-communicable diseases such as diabetes, cardiovascular diseases, and cancer. Our overarching hypothesis is that the effect of CSO consumption on oxidative stress markers (isoprostanes), inflammatory cytokines, metabolic biomarkers, and bile acid metabolism will be beneficial for reversing disease pathophysiology linked to oxidative stress, inflammation, and bile acids. Our long-term goal is to establish effective and practical therapeutic strategies utilizing dietary incorporation of CSO to prevent or reverse these diseases. The following hypotheses will be tested in the proposed investigation: H1: CSO consumption will lower exercise-induced oxidative stress, and the effect of CSO will be greater than that of OO for lowering of exercise-induced oxidative stress. H2: CSO consumption will lower inflammatory cytokines and metabolic markers linked to the inflammation process in human participants, and the effect of CSO will be greater than that of OO for lowering inflammation. H3: Features of serum bile acids, serum metabolomes, and lipidomes distinguishing CSO and OO treatment correspond to metabolic pathways illuminating the health benefits of CSO treatment. H4: Metabolic and inflammatory impacts of dietary oils will be greater for 60 g/d of CSO compared to 30 g/d.
The main objective of our study is to evaluate the effect of eye drops with antioxidants on mild to moderate dry eye symptoms in patients with diabetic retinopathy, evaluating the levels of inflammatory cytokines and oxidative stress in the tear film. The researchers intend to include 78 patients, divided into three intervention groups, who will be randomly assigned an eye drop with antioxidants, where the patient must apply one drop in each eye for 1 month. In the study, the characteristics of the surface of the eye will be evaluated and tear samples will be taken from each eye, before and after the intervention with the eye drops. Subsequently, the clinical and sample results will be evaluated to compare the effects between them.
American Indian populations continue to suffer disproportionately from health problems including such nutrition-related chronic diseases as diabetes and heart disease. This research project will therefore investigate how a traditional Indigenous food called chokeberry (Aronia melanocarpa) impacts epigenetic and metabolic health in relation to resiliency markers in American Indian participants. The process of research with American Indian communities is significant in that it can inform best practices in community engagement orientations, approaches, and models in future research settings.
The present clinical investigation has been proposed to further substantiate the evidence of the antioxidant and anti-inflammatory activity of the extract in the healthy adult population with BMI ranging from ≥25.0 kg/m2 and ≤ 34.9 kg/m2 . The antioxidant effect of the 56 days of oral administration of the extract (1000 mg/day) will be primarily assessed by change in the level of 8-isoprostane from baseline to the end of the study and the anti-inflammatory activity of the extract will be investigated by the change in the level of CRP and IL-6. In addition, the effect on lipid peroxidation and DNA damage will be assessed by serum level of MDA before and after 2 months of extract administration. Further, metabolic endotoxemia will be assessed by the change in the plasma level of lipopolysaccharides. Weight and waist circumference are included as secondary outcomes as the clinical indicators of reduction in oxidative stress and inflammation. Overweight and obesity significantly impact the health-related quality of life31 in the affected individuals and flavonoids have previously been shown to improve the quality of life in controlled clinical studies therefore, Investigator included health-related quality of life as a secondary objective of the study. The safety of the 2-month administration of the extract will be examined by a change in the vitals, liver, and kidney function biomarkers (SGOT, SGPT, ALP, and creatinine).
