Prolonged Fasting and FGF-21 Levels

2014-08-27 03:19:38 | BioPortfolio


This study will look at the effect of 72 hours of fasting (not eating) on levels of proteins that are involved in metabolism. These proteins will be measured in blood and fat tissue. The investigators' hypothesis is that fasting will cause changes in these proteins.


The purpose of this study is to examine how fasting affects levels of several proteins involved in metabolism. Studies done in animals show that fasting causes changes in proteins involved in fatty acid metabolism and the structure of fat cells. In this study, we wish to learn whether these factors change when humans are fasted.

This study will involve a 72 hour fast. During the fast, study participants may consume only water and vitamins. Participants will spend 3 days and nights in the Clinical Research Center at the Beth Israel Deaconess Medical Center. Daily blood samples will be taken, as well as two fat samples, one before the fast and one at the end of the fast.

Role of Leptin in the Neuroendocrine and Immune Response to Fasting

The purpose of this study will be to determine whether giving leptin (r-metHuLeptin) to a person when he or she is fasting will reverse changes in metabolism, and hormone levels, and immun...

Substrate Metabolism, Growth Hormone Signaling, and Insulin Sensitivity During Fasting

Background: Calorie restriction increases longevity in many species and attenuate the development of chronic disorders including type 2 diabetes, cardiovascular diseases and cancer. In mic...

Studying the Starvation Effect on Androgen Metabolism in 20 Healthy Young Women and Comparison to Women With PCOS.

The Impact of Intermittent Fasting on Human Metabolism and Cell Autophagy

InterFast is a Cohort study with an embedded randomized controlled pilot trial. Study participants will be healthy subjects and subjects who already practice Alternate Day Fasting. The tri...

Effects of PCSK9 Inhibition by Evolocumab on Postprandial Lipid Metabolism in Type 2 Diabetes

Postprandial lipemia is highly prevalent in type 2 diabetes subjects even with normal fasting triglyceride values. Humans are mostly in a postprandial rather than in a fasting state and th...

Adipose Transcriptome Analysis Provides Novel Insights into Molecular Regulation of Prolonged Fasting in Northern Elephant Seal Pups.

The physiological and cellular adaptations to extreme fasting in northern elephant seals (Mirounga angustirostris, NES) are remarkable and may help to elucidate endocrine mechanisms that regulate lipi...

Hemodilution is not the only reason of difference: Comparison of fasting and non-fasting lipoproteins in paired samples.

Low-density lipoprotein cholesterol (LDL) is an important risk factor for cardiovascular disease (CVD) and generally measured after 8-12 h fasting. However, some recent studies have pointed that non...

Predictors of Incident Type 2 Diabetes Mellitus in Japanese Americans with Normal Fasting Glucose Level.

Little is known about the natural course of normal fasting glucose (NFG) in Asians and the risk factors for future diabetes.

Prolonged fasting-induced metabolic signatures in human skeletal muscle of lean and obese men.

Insulin resistance is a well-known physiological adaptation to prolonged fasting in healthy skeletal muscle. Obesity is associated with insulin resistance and metabolic inflexibility in skeletal muscl...

The role of kidney in the inter-organ coordination of endogenous glucose production during fasting.

The respective contributions to endogenous glucose production (EGP) of the liver, kidney and intestine vary during fasting. We previously reported that the deficiency in either hepatic or intestinal g...

Medical and Biotech [MESH] Definitions

An autosomal recessive fructose metabolism disorder due to absent or deficient fructose-1,6-diphosphatase activity. Gluconeogenesis is impaired, resulting in accumulation of gluconeogenic precursors (e.g., amino acids, lactate, ketones) and manifested as hypoglycemia, ketosis, and lactic acidosis. Episodes in the newborn infant are often lethal. Later episodes are often brought on by fasting and febrile infections. As patients age through early childhood, tolerance to fasting improves and development becomes normal.

Heat production, or its measurement, of an organism at the lowest level of cell chemistry in an inactive, awake, fasting state. It may be determined directly by means of a calorimeter or indirectly by calculating the heat production from an analysis of the end products of oxidation within the organism or from the amount of oxygen utilized.

Abstaining from all food.

Hereditary disorders of pyruvate metabolism. They are difficult to diagnose and describe because pyruvate is a key intermediate in glycolysis, gluconeogenesis, and the tricarboxylic acid cycle. Some inherited metabolic disorders may alter pyruvate metabolism indirectly. Disorders in pyruvate metabolism appear to lead to deficiencies in neurotransmitter synthesis and, consequently, to nervous system disorders.

A screening phenotype consisting of both elevated WAIST CIRCUMFERENCE and elevated fasting TRIGLYCERIDES level.
