Filter by:Significant increase in the levels of serum adiponectin, ADA, and hsCRP was reported in all RA patients compared to controls. Compared to patients with early RA, the increase in these markers significantly correlated with disease activity (DAS-ESR), lower f-BMD, radiographic scoring, pain, FFI, and functional limitations in patients with established RA. Adiponectin showed a negative correlation with serum levels of both ADA and hsCRP. By using ROC curve analysis, optimal cut-off values of adiponectin (28.8 µg/ml), ADA (27.3 IU/L), and hsCRP (1.6 mg/L) could be used to estimate early RA in 45 % of the patients. Similarly, using cut-off values of adiponectin (32.8 µg/ml), ADA (26.1 IU/L ml), and hsCRP (2.5 mg/L), established RA could be predicted in 55 % of patients with 98-99% accuracy.
NIH Precision Medicine Initiative, started in May 2018, will enroll one million people through an online portal. It hopes to identify genetic variants affecting a variety of human phenotypic outcomes. A giant set of data like this may enable an association of genetic variants with a certain phenotype. However, the association is often compromised due to the collection of phenotypic data that is not well controlled or standardized creating "noisy" data. These phenotypic "noises" can be largely eliminated in clinical studies with stringent criteria and standardization of outcome measurements. In this study, by looking mainly at genetic information and nerve conduction speed, we hope to eliminate the extra "noises" in the data set. Eliminating the extra "noises" should allow us to be able to determine if there are genetic differences between neurological disorders and healthy controls, and if these genetic differences can be attributed to the speed of the nerve conduction.
The research project includes two components that assess exercise physiology parameters, cerebrovascular reserve, cognitive functions and cardiac function in coronary heart disease patients at rest, during an acute exercise, and after two different periodized training programs.
There is growing evidence that central blood pressure is a better predictor of hypertensive end-organ damage and cardiovascular outcome than routine brachial readings. The investigators aimed to evaluate the accuracy of a novel device for the non-invasive determination of central blood pressure based on automated oscillometric radial pulse wave analysis.
A pilot study, the purpose of which is to use accelerometers to quantify UE use (1 and two hand use) in healthy controls and people post-stroke from which the investigators will develop use-based feedback to improve recovery in the home setting. The objectives of this pilot study are to: i.) determine the feasibility of using accelerometers to quantify amount of UE use in the home setting in healthy individuals and individuals chronic post-stroke, ii.) quantify and compare the unilateral activity of the weaker (paretic) versus stronger (non-paretic) UEs, iii.) quantify and compare amount of UE use in healthy controls to that of people chronic post-stroke (side matched unimanual use for each arm and bilateral use) in the home, and iv.) assess the effect of a few sessions of in-home accelerometer used-based feedback on unilateral and bilateral UE use. v.) assess kinematic, kinetic, and EMG data during UE movements bilaterally and between healthy controls and subjects post-chronic stroke pre and post feedback (for the people after stroke).
This proposed project is designed to collect data and specimens from patients/subjects presenting to the University of Michigan with a disease affecting the pancreas (or specific control populations). This protocol is focused on collecting data, blood samples, and tissue on subjects with pancreatic diseases, including pancreatic cancer, pancreatic cysts, pancreatitis, diabetic controls, jaundice/biliary obstruction controls, and otherwise healthy controls. We are collecting up to 50 mls of blood for research purposes only. Plasma, serum and buffy coat are collected and stored according to strict SOPs.
In the present proposal the investigators wish to assess the effect of a single session with the device known as Exer-Rest® which applies Whole Body Periodic Acceleration (WBPA) on baseline airway blood flow (Qaw) and in Qaw variation, in current smokers, glucocorticoid-naïve asthmatics, and age-matched healthy never-smokers, with the expectation that the treatment will transiently increase the Qaw, and to a greater extent in the current smokers and patients with asthma who have endothelial dysfunction.
The principal purpose of this study is to identify hyper-responsive, responsive and non-responsive groups of healthy human subjects based on their airway neutrophilic response to ozone exposure, and to perform micro-array analyses on DNA collected from recovered airway cells to explore possible differences in gene expression profiles between the three groups
