Filter by:Light and ultrasound can be interesting alternatives to reduce abdominal fat. Thus, the main objective of this study will be to evaluate the effects of these isolated techniques and their association in subcutaneous abdominal localized fat. These techniques will be used adding muscle electrostimulation in all groups. A total of 40 female participants will be recruited at the university outpatient, which will be distributed among four experimental groups: light + sham ultrasound + electrostimulation; light sham + ultrasound + electrostimulation; combined treatment (light + ultrasound) + electrostimulation; sham combined treatment + electrostimulation. The treatments will consist of eight sessions, twice a week for a month, being 90 minutes per session.
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.
The goal of this clinical trial is to determine the effect of elevated plasma ceramides on peripheral vascular function. Subjects will consume a high fat meal consisting of long chain fatty acids (to increase plasma ceramides) or medium chain fatty acids (control). Subjects' vascular function will be assessed with laser Doppler flowmetry to measure their artery function and with the CytoCam device to assess their peripheral microvascular endothelial function.
Heart failure with preserved ejection fraction (HFpEF) was considered as a heterogeneous disease with multi-organ and multi-system design, which is related to various complications, such as hypertension, obesity and arteriosclerosis. Studies have found that hypertension and obesity are respectively associated with increased arterial stiffness. However, there is still no research investigating the the relationship between lipids distribution and arterial stiffness in HFpEF patients.
The excess of localized fat causes changes in the body contour and consequently changes in the properties of the skin and in the connective tissue, providing sagging skin. Tecartherapy known as High Frequency Capacitive and Resistive Electrical Transfer Therapy (Tecartherapy) emerged to contribute to the treatment of these aesthetic affections, it is a non-invasive electrothermal therapy that acts on cell biostimulation through tissue heating and can help to reduce fat localized and improve the aspect of flaccidity, through the stimulation of neocollagenesis and neoelastogenesis. This is the aim of this research is to evaluate the effects of Tecartherapy on localized fat and abdominal skin flaccidity with clinical and histological results. The sample will have 61 participants, who will be evaluated pre and post treatment through evaluation protocols, photographs and questionnaires. The research will have two treatment groups. Being Group 1: Tecartherapy and Group 2: placebo (equipment turned off). 10 Tecartherapy sessions will be held once a week in the abdominal region and flanks. The parameters used will be: for an area of 300cm², 1MHz, Capacitive Mode: 60mm Disk, Default 100W, Time of 10 minutes, keeping temperature up to 42ºC, Resistive Mode: 60mm Disk: Default 110W, Time of 10 minutes, keeping temperature up to 42ºC, with a total treatment time of 20 minutes for the 300cm² area. After treatment, a biopsy of the subcutaneous tissue and skin will be performed in a volunteer, the tissue will be collected during the surgical procedure of abdominoplasty for histological analysis. The reassessment will be carried out three times, being 30, 60 and 90 days after the initial session, with the repetition of all mentioned exams and photos for analysis of the results, of all participants.
The aim of the study is to evaluate modifications in the metabolism of polyunsaturated fatty acids (PUFA) and biosynthesis of the lipid mediators N-acylethanolamines (NAE), both known to induce and be induced by the nuclear peroxisome proliferator-activated receptor (PPAR)-α, which may also explain the well-established improved lipid and energy metabolism after bariatric surgery. The study is focused on understanding the weight loss mechanisms in order to develop targeted dietary protocols.
IBI306 is a bio-innovative drug against proprotein convertase subtilisin 9 (PCSK-9) monoclonal antibody. Currently, cholesterol-lowering drugs with multiple mechanisms of action are on the market or under development. Among them, anti-PCSK-9 monoclonal antibodies have received widespread attention due to their good safety and efficacy. The results of existing preclinical studies show that IBI306 has a clear structure, good stability, and is not inferior to other drugs of its kind in terms of drug activity, animal pharmacokinetics (PK)/pharmacodynamics (PD) and safety. This study is divided into two phases: the dose exploration phase (the first phase) and the confirmatory phase (the second phase). Each stage is divided into screening period, treatment period, and safety follow-up period. The first phase of this research is the randomized design of open labels. The second stage is an open, single-arm design. The main purpose of the first phase of the study: to evaluate the tolerability and safety of multiple-dose repeated administration of IBI306 in the Chinese population with hypercholesterolemia, and to recommend the dose for the second phase. The main purpose of the second phase of the study: to evaluate the effectiveness of IBI306 in the Chinese homozygous familial hypercholesterolemia population. Secondary research purpose: To evaluate the safety and immunogenicity of IBI306 in Chinese homozygous familial hypercholesterolemia population.
The study is a randomized, cross-over, double-blind, controlled trial in which participants with mildly elevated levels of cholesterol will receive two 4-week interventions (e.g. kori-tofu or control), with a wash-out period of 4 weeks in between. During the intervention periods, subjects will eat 3 slices of bread per day, representing a Kori-tofu dose of 34.5 grams or a matched reference. Fasting total and LDL cholesterol will be determined at the start and end of each of the two intervention periods.
Retrospective observational study of the efficacy and safety of statin monotherapy or statins in combination with ezetimibe in patients receiving lipid-lowering therapy in both primary and secondary prevention of cardiovascular diseases (CVD). The study will include patients receiving lipid-lowering therapy in both primary and secondary prevention of CVD who have received therapy of interest for ≥ 3 months in the 2 years preceding the signing of informed consent, i.e. statins as monotherapy or in combination with ezetimibe in a stable mode (without dose adjustment and/or statin replacement). Effectiveness of therapy will be evaluated based on the data on changes in baseline levels of total cholesterol (CS), low density lipoproteins (LDL), high density lipoproteins (HDL), triglycerides (TG), data on which will be obtained from primary medical records. Demographic and anthropometric data on patients, information on the history of hyperlipidemia and concomitant diseases will also be obtained. Also, the study will collect data on the development of adverse reactions of particular interest during therapy (liver/muscle damage, major cardiovascular events (MACE).
A systematic collection of retrospective and prospective data based on non-interventional patient observation, aimed to assess the risks, course and outcomes of a disease or a group of diseases: - the retrospective part: database of patients with cardiovascular risks; - the prospective part: observation of patients in the real world medical practice.
