When muscles are not contracting, the local energy demand by muscle and use of specific fuels used to produce energy by oxidative metabolism are minimal. The time people spend sitting inactive (sedentary time) typically comprises more than half of the day. This sedentary behavior is associated with elevated risk of diabetes, cardiovascular diseases, some cancers, and multiple conditions leading to poor aging. From a progressive series of experiments, the driving goal is to develop a physiological method for sustaining contractile activity via oxidative metabolism over more time than is possible by traditional exercise (hours, not minutes per day). Developing a physiological method suitable of prolonged muscular activity for ordinary people (who are often unfit) requires gaining fundamental insights about muscle biology and biomechanics. This also entails a careful appreciation of the ability to isolate specific muscles in the leg during controlled movements, such as the soleus muscle during isolated plantarflexion. This includes quantifying specific biological processes that are directly responsive to elevated skeletal muscle recruitment. The investigators will focus on movement that is safe and practical for ordinary people to do given their high amount of daily sitting time. This includes developing methods to optimally raise muscle contractile activity, in a way that is not limited by fatigue, and is feasible throughout as many minutes of the day as possible safely. This also requires development of methodologies to quantify specific muscular activity, rather than generalized body movement. There is a need to learn how much people can increase muscle metabolism by physical activity that is perceived to them as being light effort. It is important to learn if this impacts systemic metabolic processes under experimental conditions over a short term time span in order to avoid confounding influences of changes in body weight or other factors.
This prospective study aims to assess the feasibility and implementation of a plant-based, weight-loss program in an office setting. The study will also assess changes in body weight, blood pressure, plasma lipids, glycated hemoglobin, and body composition with a 12-week, plant-based, weight-loss program. These health benefits may illustrate feasibility to physicians and healthcare professionals elsewhere.
The rationale of this research is that deep phenotyping of individuals at the extremes of cholesterol efflux will identify key determinants of efflux that are potential novel therapeutic targets to prevent or reverse Atherosclerotic Cardiovascular Disease (ASCVD). The investigators propose to carry out the objective by studying participants at extreme low and high cholesterol efflux identified from the investigator's study in the population-based Dallas Heart Study by accomplishing the following aims: 1) determine the heritability of and genomic factors associated with cholesterol efflux by establishing a family pedigree of extreme low and high efflux and sequencing candidate genes involved in HDL metabolism; and 2) identify the protein and lipid signature of extreme low and high cholesterol efflux in a sex- and ethnicity-specific manner using mass spectroscopy and ELISA in FPLC-derived fractions. The investigators expect to identify genetic variants and sex- and ethnicity-specific combinations of proteins and lipids in participants with extreme low and high efflux that may lead to novel ways to modulate efflux. This proposal leverages a well-phenotyped population-based study to characterize the gene-protein-lipid signature of 1) extremes of cholesterol efflux in a sex- and ethnicity-specific manner. Successful completion of these aims will have immediate and direct impact on the use of cholesterol efflux as a clinically relevant biomarker of therapeutic benefit and are necessary for the clinical development of appropriate new targets for manipulation of the key atheroprotective function of cholesterol efflux to reduce ASCVD.
The purpose of this study is to evaluate the safety and efficacy of sequential use of CoolSculpting (Cryolipolysis) and radiofrequency treatment of the submental and submandibular area.
The purpose of this study is to evaluate the safety and efficacy of non-invasive reduction of subcutaneous fat along the jawline with Cryolipolysis.
Evaluate the safety and efficacy of non-invasive subcutaneous fat layer reduction in the flanks.
The purpose of this study is to collect data to help researchers identify factors, such as certain proteins or genetic codes, that are secreted from muscle that are associated with the beneficial effects of exercise.
The Physical Activity and Nutrition in Children (PANIC) Study is a single-centre controlled trial on the effects of a combined physical activity and dietary intervention on cardiometabolic risk factors and other health outcomes in a population sample of children from the city of Kuopio, Finland. The study provides novel scientific information for the identification of cardiometabolic diseases and other chronic diseases since fetal period and for the prevention of these chronic diseases since childhood. The main hypothesis of the PANIC study is that individuals at increased risk of cardiometabolic diseases and other chronic diseases can be identified in childhood and that it is possible to start the prevention of these chronic diseases by a long-term physical activity and dietary intervention since childhood.
Closer examination of granular lipid data in a large population offers numerous opportunities to generate new knowledge, ranging from studies examining concordance between commonly used lipid parameters to phenotypic characterization of rare or extreme disorders of lipid metabolism, opening possibilities to better personalize future treatment of abnormal blood lipids. STUDY POPULATION: The Very Large Database of Lipids (VLDL) includes adults and children who were clinically referred for a Vertical Auto Profile (VAP). Patient samples originated predominantly from outpatient primary care clinics in the U.S. (85%), along with specialty clinics and inpatient settings. LIPID MEASUREMENTS: The VAP test (VAP Diagnostics Lab, Birmingham, Alabama, USA) directly measures cholesterol concentrations of low density lipoprotein, very low density lipoprotein, intermediate density lipoprotein, high density lipoprotein, their subfractions, and lipoprotein(a). Triglycerides in the database are directly measured using the Abbott ARCHITECT C-8000 system (Abbott Park, Illinois, USA). Lipid distributions in the database closely match those from the population-representative National Health and Nutrition Examination Survey (NHANES). STUDY PROCEDURES: This database was investigator-initiated. Only de-identified data reach the investigational site. The master database is housed at The Johns Hopkins Hospital in Baltimore, Maryland, and maintained by Drs. Jones and Martin. The current database (2nd harvest) includes 5,051,467 patients whose laboratory samples were collected from October 1, 2015 and June 30, 2019. Only electronic data, and not blood samples, are sent to Hopkins. The academic investigators have unrestricted access to study data, take responsibility for the accuracy of analyses, and have authority over manuscript preparation and submission. VARIABLES: The variables currently in the VLDL database are testing date, age, sex, fasting/nonfasting, and components of the VAP test. From these primary variables, many additional variables were derived for inclusion in the master database. Other analytes measured by validated assays in subsets of the VLDL database include apolipoprotein B (apoB), apolipoprotein A1 (apoAI), high-sensitivity C-reactive protein (hsCRP), homocysteine, uric acid, insulin, hemoglobin A1c, 25-hydroxy vitamin D, cystatin C, lipoprotein-associated phosphatase (Lp-PLA2), thyroid stimulating hormone (TSH), free T3 and T4, pro-brain natriuretic peptide (pBNP), direct bilirubin, creatine phosphokinase (CPK), creatinine and other components of the comprehensive metabolic panel, magnesium, and phosphate.
