Filter by:The present study will compare the effect of Manapol to DaltonMax on select measures of health. Currently, both ingredients are sold both as a stand-alone dietary supplement and as an active ingredient within various multi-nutrient products. Immune function will be assessed using blood samples to determine white blood cell counts and distributions, and cytokine levels with/without lipopolysaccharide (LPS) challenge. Additionally, effects specific to antioxidant function and glucose regulation, glucose, insulin, lipid peroxidation, and advanced oxidation protein products will be observed. Antioxidant capacity will also be measured. as well as completion of weekly questionnaires regarding gut health, and microbiome analysis.
This study is designed to investigate the health impact of a vegan diet compared to a usual, omnivorous diet. The investigators plan to study these diets in twins, where one twin follows a vegan diet and the other twin follows an omnivorous diet, thus the investigators control for genetic differences that might impact the effect of the diet.
Gut microbiome manipulation to alter the gut-lung axis may potentially protect humans against respiratory infections. However, clinical trials of synbiotics, one of the microbiota-targeted intervention, in this regard is few. Therefore, this study aims to examine the effect of synbiotics on the incidence and severity of upper respiratory tract infection, gut microbiota composition and function, as well as biomarkers of immune function.
Assess the impact of a proprietary extract of Nerium oleander on immune function as evidenced by COVID-19 symptoms and mortality in COVID-19 positive patients and their close contacts compared to controls that did not receive the extract.
This study aims to investigate the impact of replacing meat consumption with plant-based meat alternative consumption on cardiovascular health, the gut microbiome, and metabolic status.
An individual's immune and metabolic status is coupled to consumed carbohydrates. Complex carbohydrates that are not digested by human enzymes may influence host biology by impacting microbiota composition and function, or act in a yet-unknown microbiota-independent manner. Prebiotics offer a promising safe route to influence host health, possibly via the microbiota. However, it remains largely unknown to what extent immune function and metabolism can be modulated by prebiotics.
The impact of different anesthetic techniques on the immune system remains unclear. Aim of this ex vivo / in vitro study was to determine the effects of general and neuraxial anesthesia on monocyte subset alteration and the release of prototypical pro- and anti-inflammatory cytokines. Twenty patients undergoing total knee replacement surgery were randomly assigned to receive either general anesthesia (ITN) or combined spinal/epidural anesthesia (CSE). CD14 and HLA-DR expression patterns on monocytes and intracellular TNF-alpha production were quantified via flow cytometry. TNF-α and IL-10 release were measured via enzyme linked immunosorbent assay (ELISA).
The researchers investigated the immune enhancing effects of AGP for Korean participants.
The primary objective is to contrast the degree to which increased consumption of dietary fiber vs. fermented food can decrease inflammation, increase microbiota diversity and can impact microbiota production of short-chain fatty acids (SCFA), potential normalizers of metabolic and immune dysfunction, in obese and non-obese adults.
A The aim of this study was to investigate the impact of consuming Weissella cibaria (W. cibaria) JW15 supplementation isolated from Kimchi, Korea traditional fermented food, on natural killer (NK) cell activity and circulating levels of cytokines and immunoglobulin (Ig).
