12 obese subjects will receive peripheral administration of placebo and 4 escalating doses of PYY1-36 and another 12 obese subjects will receive peripheral administration of placebo and 4 escalating doses PYY3-36 on 5 different test days within one week. The patients will be tested in a single blinded dose escalating protocol. Measurements of appetite, ad libitum energy intake, blood pressure and blood sampling will be performed during the test day.
Allocation: Non-Randomized, Control: Placebo Control, Endpoint Classification: Efficacy Study, Intervention Model: Crossover Assignment, Masking: Single Blind, Primary Purpose: Treatment

Accumulating evidence suggests that the natriuretic peptide (NP) hormonal system has important effects on metabolism. However, more information is needed to better understand the effects o...
To evaluate the safety and immunogenicity of a combination of microparticulate monovalent HIV-1 MN synthetic branched peptide candidate vaccine for oral administration and monovalent HIV-1...
The investigators are examining: 1. the relationships of insulin levels and natriuretic peptide hormone levels, and 2. the effects of administering an infusion of natriuretic peptide...
To evaluate the chemical efficacy and safety of intranasally administered peptide T on neurocognitive function in HIV seropositive individuals. Previous studies have shown that treatment ...
The study is a phase I multicentre randomized, open, parallel-arm clinical trial conducted to investigate the IMP, namely 111In-CP04. The study consists of preclinical (to establish a cli...
Despite greater health education, obesity remains one of the greatest health challenges currently facing the world. The prevalence of obesity among children and adolescents and the rising rates of pre...
Acute effects of intravenous cocaine administration on serum concentrations of ghrelin, amylin, glucagon-like peptide-1, insulin, leptin and peptide YY and relationships with cardiorespiratory and subjective responses.
Food intake and use of drugs of abuse like cocaine share common central and peripheral physiological pathways. Appetitive hormones play a major role in regulating food intake; however, little is known...
Hypothalamic damage may alter glucagon-like peptide-1 (GLP-1) secretion and be involved in the pathogenesis of obesity. We aim to evaluate the metabolic features and the dynamic changes of GLP-1 level...
Several chemotherapeutic agents used for cancer treatment induce dose-limiting peripheral neuropathy that compromises patients' quality of life and limits cancer treatment. Recently, mitochondrial dys...
Spexin, a novel peptide, has potential implications in obesity, satiety and energy homeostasis. The current study examined the relationship of spexin with various biomarkers of cardiovascular disease ...
A 27-amino acid peptide with histidine at the N-terminal and isoleucine amide at the C-terminal. The exact amino acid composition of the peptide is species dependent. The peptide is secreted in the intestine, but is found in the nervous system, many organs, and in the majority of peripheral tissues. It has a wide range of biological actions, affecting the cardiovascular, gastrointestinal, respiratory, and central nervous systems.
A condition of having excess fat in the abdomen. Abdominal obesity is typically defined as waist circumferences of 40 inches or more in men and 35 inches or more in women. Abdominal obesity raises the risk of developing disorders, such as diabetes, hypertension and METABOLIC SYNDROME X.
Administration of a drug or chemical by the individual under the direction of a physician. It includes administration clinically or experimentally, by human or animal.
The production of PEPTIDES or PROTEINS by the constituents of a living organism. The biosynthesis of proteins on RIBOSOMES following an RNA template is termed translation (TRANSLATION, GENETIC). There are other, non-ribosomal peptide biosynthesis (PEPTIDE BIOSYNTHESIS, NUCLEIC ACID-INDEPENDENT) mechanisms carried out by PEPTIDE SYNTHASES and PEPTIDYLTRANSFERASES. Further modifications of peptide chains yield functional peptide and protein molecules.
A 30-kDa protein synthesized primarily in the ANTERIOR PITUITARY GLAND and the HYPOTHALAMUS. It is also found in the skin and other peripheral tissues. Depending on species and tissues, POMC is cleaved by PROHORMONE CONVERTASES yielding various active peptides including ACTH; BETA-LIPOTROPIN; ENDORPHINS; MELANOCYTE-STIMULATING HORMONES; and others (GAMMA-LPH; CORTICOTROPIN-LIKE INTERMEDIATE LOBE PEPTIDE; N-terminal peptide of POMC or NPP).
Obesity is the condition in which excess fat has accumulated in the body (mostly in subcutaneous tissues). clinical obesity is considered to be present when a person has a BMI of over 30 (Oxford Dictionary of Medicine). It is becoming increasing common i...
