Filter by:There are experimental evidences of the importance of high intensity exercises in health outcomes improvement. However, there are limited knowledge about possibility to affect health outcomes in adolescents through exercises programs introduced into physical education (PE) lesson. Moreover, there is lack of the studies identifying people who do not respond to stimuli, as well as examining potential determinants of non-responsiveness. Thirdly, there are no studies examining the modification of exercise dose that should be reflected in the response in such individuals. Aim of this human experiment is to examine the effects of one cycle of 8-weeks high-intensity interval training (HIIT) implemented in physical education lesson on: (1) body composition (proportions of the body fat to the body muscles), (2) resting blood pressure, (3) physical efficiency. Study are conducted for two years (two cycles). Each year 300 students of two secondary schools, are involved in project: 15-16-year-olds in first year, 18-19-year-olds in second year. Students are divided in experimental groups -performing 8-weeks (twice a week) cycle of HIIT implemented into PE lesson, and the control groups - students following a typical PE programme. Each cycle consists of two parts. First part is related to the 8 weeks of HIIT training, while second part is related to the dose-expose study. All participants are examined during project before (Pre), after (Post) and Follow-Up intervention. Second part is planned after a break of several months. Persons who do not respond to the exercise stimulus in the first part will follow individually modified programmes. They will be measured before and after this additional training. To examine the assumed HIIT-induced changes in participants the investigators will apply: (1) anthropometric measurements: body height and weight, and BMI will be calculated, (2) body mass composition (fat and muscle mass), (3) resting blood pressure, (4) beep test which is field motor specific test to assess physical efficiency. The results of this project will help to answer the fundamental questions about HIIT induced morphological and physiological effects in adolescents, what is important from scientific and public health point of view. Particularly, in view of the growing pandemic of obesity, common elevated blood pressure and steadily declining physical fitness in children and adolescents.
The experiment is a simple cross-sectional study with three groups (n=10) in each group, young and old healthy men and obese young men. The study will investigate the composition of the adipose tissue extra cellular matrix. The main questions to answer, - is there differences in the adipose tissue extracellular matrix in obese compared to young men is there differences in the adipose tissue extracellular matrix in old compared to young men
The purpose of this research is to collect data on the short and long-term effects of facial fat grafting by injectable tissue replacement and regeneration in the midfacial zone, with the use of the VialityTM system. The Viality system is a US Food and Drug Administration (FDA) cleared device.
The aim of the study is to verify the efficacy of microfragmented autologous adipose tissue with the Lipogems® system, in the treatment of perianal fistulas of m. Crohn's. The Lipogems® International, Milan, Italy, system is a sterile and disposable device that allows to harvest adipose tissue, process it and use it for intraoperative autologous transplantation of human adipose tissue mesenchymal cells that have a gene expression profile and phenotypic similar to that of adipose stem cells. The system consists of a container with metal beads capable of carrying out, by handling, a mechanical micro-fragmentation of the lipoaspirate and of a washing and filtering system which allows to progressively reduce the size of the adipose tissue clusters down to 0.2-0.8 mm and eliminate blood and oily residues. The processed Lipogems® is fluid and easily injectable and is rich in mesenchymal cells and pericytes. The processed Lipogems® will be injected around the fistulous tract and the tissue area closing the internal orifice to promote healing.
Muscle mass loss is a common adverse effect of cancer. Muscle mass loss occurs with or without reduction in body weight. Cancer cachexia (CC) is the involuntary loss of body weight of >5% within 6 months and it occurs in 50-80% of patients with metastatic cancer. It is estimated that CC is a direct cause of up to 30% of all cancer-related deaths. No treatment currently is available to prevent CC, likely because the chemical reactions that causes of this devastating phenomenon in unknown. No treatment currently is available to prevent muscle mass loss in patients with cancer but is urgently needed as the reduced muscle mass and function is associated with impaired physical function, reduced tolerance to anticancer therapy, poor quality of life (QoL), and reduced survival. There is evidence of an interdependence between informal caregiver (e.g. spouse) and patient QoL. Thus, identifying caregiver distress and needs can potentially benefit QoL for patients with cancer cachexia. Despite the enormous impact on disease outcomes, it is not known why the loss of muscle mass and function occurs and very few studies have investigated the underlying molecular causes in humans. In particular, there is a severe lack of studies that have obtained human skeletal muscle and adipose tissue sample material. Such reference sample materials will be invaluable to obtaining in-depth molecular information about the underlying molecular causes of the involuntary but common muscle mass and fat mass loss in cancer. At a whole body level, cancer cachexia is associated with reduced sensitivity to the hormone insulin, high levels of lipids in the blood, and inflammation. Within the skeletal muscle, the muscle mass loss is associated with elevated protein breakdown and reduced protein build-up while emerging, yet, limited data also suggest malfunction of the power plants of the cells called mitochondrions. The role of malnutrition and how it contributes to weight loss is understood only to the extent of the observed loss of appetite and the reduced food intake because of pain, nausea, candidiasis of the mouth, and breathlessness. Evidence is increasing that the environment of the intestinal system could be implicated in cancer cachexia, yet, the possible effect of cancer and the cancer treatment on the intestinal environment is not understood. Thus, large and as yet poorly understood details of this syndrome precede a later weight loss. Exercise training could help restore muscle function and how the chemical reactions works in cancer. In healthy people, and patients with diabetes, cardiovascular disease, and obesity exercise potently improves health. Exercise has been thought to slow down the unwanted effects of cancer cachexia by changing the reactions mentioned above. Thus, there is a tremendous gap in our knowledge of how and if exercise can restore the cells power plants function, muscle mass, strength, and hormone sensitivity in human cachexic skeletal muscle. Tackling that problem and examining potential mechanisms, will enable us to harness the benefits of exercise for optimizing the treatment of patients with cancer. The data will provide novel clinical knowledge on cachexia in cancer and therefore addressing a fundamental societal problem. Three specific aims will be addressed in corresponding work packages (WPs): - investigate the involvement of hormone sensitivity of insulin and measure the chemical reactions between the cells in patients with lung cancer (NSCLC) and describe the physical performance and measure amount of e.g. muscles and adipose tissue across the 1st type of cancer treatment and understand how that is related to the disease and how patients and informal caregiver feel (WP1). - find changes in the chemical reactions in skeletal muscle, adipose tissue (AT), and blood samples in these patients, to understand how to predict how the disease will develop (WP2). - measure changes of skeletal muscle tissue in response to exercise and see if it might reverse the hormone insensitivity and improve muscle signaling and function (WP3). The investigators believe that: - the majority of patients with advanced lung cancer, at the time of diagnosis already are in a cachectic state, where they lose appetite, and have hormonal changes, and an overall altered chemical actions between the cells affecting both muscle mass and AT. The investigators propose that all this can predict how the disease will progress, and how patient- and informal caregiver fell and how they rate their quality of life. - lung cancer and the treatment thereof is linked with changes in the blood, the muscle tissues, and the adipose tissues, especially in patients experiencing cachexia, that could be targeted to develop new treatment. - exercise can restore the muscles and improve insulin sensitivity and improve the function of the cells power plants in patients with lung cancer-associated muscle problems.
Cancer cachexia is defined as a weight loss of more than 5% over the last 6 months, a loss of body fat and muscle atrophy. It is found in 80% of patients with advanced cancer. In this context, white adipose tissue is a particularly interesting target since its depletion precedes the loss of muscle mass, and is sufficient to induce a decrease in the response to anti-cancer treatments and in the survival of patients. This cachexia is associated with advanced tumors that present acidosis and metastasis. In this clinical study the investigators would like explore the acid environment effect on the human adipose tissue depletion and more specifically on adipocyte lipolysis. The main objective of the "TuLip" clinical study is therefore to validate in human subcutaneous and visceral adipocytes that factors secreted by tumor cells cultivated in acid tumor environment stimulate the release of lipids from adipose tissue. Adipocytes retrieves from this study will also be used to validate identified potential lipolytic factors derived from these cells.
This study investigated the cellular and molecular characteristics of AT-MSCs obtained from autologous AT therapy in patients with high transphincteric perianal fistulas of crytoglandular origin. Adipose tissue was injected into anal fistulas. Characteristics of adipose tissue mesenchymal stemcells (AT-MSC) was investigated and compared in patients with fistula that healed after the treatment (responders) to patients who failed to heal (non-responders)
This study is designed to provide objective evidence regarding the safety of eon® treatment of the flanks.
This is a community project carried out jointly by the Technological Institute of Higher Studies of the West (ITESO), the University Center of Tonalá of the University of Guadalajara (CUTonalá) and the University Center of Health Sciences of the University of Guadalajara ( CUCS) with advice from the National Institute of Public Health (INSP), financed by the Tresmontes Lucchetti company and endorsed by the Jalisco Association of Nutritionists, AC (AJANUT). This project follows the provisions of the "National Strategy for the Prevention and Control of Overweight, Obesity and Diabetes" signed by the executive branch of the Federal Government. In particular, this project is inserted within the Public Health Strategy, in the strategic axis of Health Promotion and educational communication (while still having an impact on the axes of Epidemiological Surveillance and Prevention). In addition, it follows the agreement in which the general guidelines for the expenditure and distribution of food and beverages prepared and processed in the schools of the National Educational System were obtained, proposed by the Ministries of Health and Public Education. The aforementioned referrals are intended to protect and improve the health of Mexican children.
Brown fat is a type of fat, found in both children and adults, which can produce heat and regulate the body's metabolism and energy use. White fat is the more common type of fat which is used to store extra calories. Understanding more about differences between brown and white fat may allow us to develop new approaches to improve the body's metabolism.
