Recently, two novel highly selective mu-opioid receptor (MOR) agonists, endomorphin-1 and endomorphin-2, have been isolated from bovine as well as human brains and were proposed to be the endogenous ligand for MOR. Later, endomorphin-1 and…

Background: Pediatric patients with advanced cancer and their caregivers have unique psychosocial needs. Anxiety often worsens throughout treatment for both patients and parents, and, if undertreated, can cause suffering. Animal-assisted interaction…

OBJECTIVE: This multicenter, parallel-group, randomized trial examined the effects of an animal-assisted intervention on the stress, anxiety, and health-related quality of life for children diagnosed with cancer and their parents. METHOD: Newly…

OBJECTIVE: To evaluate changes in resting energy expenditure (REE) as well as protein and carbohydrate metabolism in dogs with osteosarcoma (OSA). ANIMALS: 15 weight-stable dogs with OSA that did not have other concurrent metabolic or endocrine…

There has been a dramatic change in the therapeutic approach to patients with Paget's disease of bone over the last 40 years. In the 1960s, only symptomatic therapy could be given, with control of pain the main objective. Analgesics and nonsteroidal…

Loss of body weight in cancer patients strongly influences morbidity and mortality. Recent studies have suggested that both tumor and host factors play a major role in tissue catabolism in cachexia, leading to upregulation of degradative pathways in…

Discovering the hormonal and neural mechanisms that promote affiliative social behavior is a high priority in behavioral neuroscience. Although studies with standard laboratory rodents have afforded many important insights, exciting advances are also…

Mechanisms that lead to cachexia are still poorly understood. The neurohormonal changes that occur in severe disease states may cause an imbalance between protein synthesis and degradation at the cellular level, followed by muscle wasting. Here, we…

Endomorphin (EM)-1 and EM-2 are opioid tetrapeptides, reported within the central nervous system, which have very high specificity and affinity for the mu-opioid receptor. We have used newly developed and well-characterised radioimmunoassays (RIAs)…

This study is concerned with dynamic processes that underly the rapid, degenerative changes associated with the "dying" stage of the multicellular organism's life cycle. The interaction between negative and positive feedback cycles is discussed:…

In this review a case is presented for the use of mathematical modelling in the study of pain. The philosophy of mathematical modelling is outlined and a recommendation is made for the use of modern nonlinear techniques and computational neuroscience…

Opioids are the most effective and widely used drugs in the treatment of severe pain. They act through G protein-coupled receptors. Four families of endogenous ligands (opioid peptides) are known. The standard exogenous opioid analgesic is morphine.…

This study investigated the involvement of endogenous opioid peptides in mediating cold water swim (CWS) stress-induced antinociception (SIA) in rats with unilateral hind paw inflammation induced by Freund's complete adjuvant (FCA). Following 0.5, 1…

Basal and dexamethasone-suppressed adrenal glucocorticoid secretion and hypothalamic beta-endorphin (BE) release in vitro were investigated in rats deprived of food for 24, 48, 72, and 96 h. Fasting for up to 48 h neither caused significant changes…

This presentation will cover the history, recent developments in, and implications of the ability of both the immune and neuroendocrine systems to produce POMC. The discovery of POMC in immune cells was one of the events that heralded a molecular…

Proopiomelanocortin (POMC) is the polypeptide precursor of ACTH. First discovered in anterior pituitary corticotroph cells, it has more recently been revealed to have many other physiological aspects. The fine molecular mechanisms of ACTH…

This manuscript reviews the use of an off-line combination of liquid chromatography (LC) and mass spectrometry (MS) to quantify endogenous neuropeptides in biological tissues and fluids, and tandem MS (MS/MS) to optimize the molecular specificity of…

Chronically painful conditions are frequently associated with sleep disturbances, i.e. changes in sleep continuity and sleep architecture as well as increased sleepiness during daytime. A new hypothesis, which has attracted more and more attention,…

Numerous causes of pneumothorax, pneumomediastinum, and pneumopericardium have been described in the literature. The authors report a unique case in which one or more causes may have contributed to the patient's condition.
