Longevity

The goal of this observational study is to learn about the long-term effects of Dezawa MuseCells to treat various diseases. The Primary Goal: What is the short-term and long- term outcomes of Dezawa Musecells? Participants treated with Dezawa MuseCells as part of their regular medical care and will answer online survey questions about symptoms and clinical outcomes for 5 years.

Examining the effects of PeptiStrong and protein on muscle function in older adults

The goal of this clinical trial is to learn if daily collagen peptide supplementation can stabilize or lengthen telomeres and improve related markers of cellular aging in adults aged 50-70 years with overweight and low-to-moderate physical activity (healthy volunteers without major chronic disease). Main questions it aims to answer are: Does six months of collagen peptides stabilize or extend telomere length and increase telomerase activity compared with placebo? Are any telomere-related changes associated with lower inflammation, healthier body composition, and better functional health? Researchers will compare collagen as an intervention to a placebo group to see if collagen will influence aging markers. Participants will take collagen peptides or a placebo daily for 24 weeks. They will attend three study visits: one before starting the intervention (T0), one at 3 months (T1), and one at 6 months (T2). At each visit, blood samples will be collected to measure telomere length, telomerase activity, and inflammation/redox markers. Participants will also undergo body composition assessments using bioelectrical impedance, complete functional tests of muscle strength and mobility, and fill out questionnaires on health and vitality.

This study is a multi-site clinical trial designed to evaluate how the body absorbs and processes Kaempferol, a naturally occurring compound found in many plant-based foods. The primary purpose of the study is to measure the pharmacokinetics and biological absorption of Kaempferol in healthy adults. Participants will receive Kaempferol and undergo scheduled blood and urine collections over a short study period. These samples will be used to measure Kaempferol levels in the body and to assess safety and tolerability. In addition, selected biological samples will be analyzed to explore molecular changes associated with Kaempferol exposure using advanced laboratory methods. The study will be conducted at multiple research centers in the United States using a standardized protocol to ensure consistency across sites. The information collected will help improve understanding of how Kaempferol is absorbed and metabolized in humans and will support future research and regulatory evaluation.

This study investigates whether taking the amino acid L-serine, either alone or in combination with targeted strength training, can have a positive effect on mental performance, brain function, and physical fitness in older people. Healthy, independent women and men aged 65 to 85 are eligible to participate. Participants will be randomly assigned to one of three groups: placebo, L-serine, or L-serine combined with strength training. Cognitive tests, physical performance tests, and blood and brain tests will be conducted over a period of 48 weeks. The aim is to gain a better understanding of how nutrition and exercise can contribute to healthy aging.

The goal of this randomized, controlled trial is to evaluate the effectiveness of alternative therapies (metformin alone, with rapamycin, and with low-dose naltrexone) in maintaining weight loss in patients weaning off GLP-1 medications. The main questions it aims to answer are: * Whether the combination of metformin, with or without rapamycin or low-dose naltrexone, will be adequate to maintain the relative weight of individuals gradually discontinuing GLP-1 receptor agonist use. * Whether individuals discontinuing GLP-1 receptor agonist use who instead use a combination of metformin, with or without rapamycin or low-dose naltrexone, will experience less weight regain over the course of six months post-cessation than those who do not use any alternative medications. Researchers will compare the four groups: 1) control, 2) metformin, 3) metformin + rapamycin, and 4) metformin + low-dose naltrexone, to assess changes in the percentage of weight regain, metabolic indicators (e.g., HbA1c, lipid profile), and quality of life PROs, six months after cessation of GLP-1 therapy. Participants will: * Administer the assigned intervention following a dosing and administration protocol provided by the study and medical team. * Complete a medical intake for overall health status, medical history and demographic information, * Complete patient-reported outcomes/surveys and assessments * Complete blood work at baseline and every 16 weeks thereafter to measure CBC, CMP, and standard health biomarker panels (e.g., cholesterol, glucose, creatinine, sodium, potassium). * Share data from health wearables with the research team throughout the study to improve the accuracy of evaluating activity, sleep, heart rate, and other related healthspan measures.

The demographic life expectancy enhancement of the past 150 years imposes an urgent challenge in Western and economically growing societies to stimulate the healthy lifespan that is lagging behind. Families surviving into exceptionally high ages (longevity) in good physical and mental health illustrate that this is physiologically possible. Such families harbor cross generational socio-genetic mechanisms that mediate healthy aging and protection from (multi)morbidity. The purpose of our research is: to identify gene variants associated with healthy aging and protection from (multi)morbidity; to study the social-, environment- and behavioral factors of familial longevity, their role in (multi-)morbidity and its interaction with the genetic component.
