OBJECTIVES: The focus of this review was on proteins and peptides found in saliva. Of greatest interest were those neuropeptides relevant to nociception and to the pathogenesis of chronic pain syndromes. An additional goal was to develop a…

Beta-endorphin (BE) and cholecystokinin (CCK) were measured in fresh PBMC isolated from human subjects and rats. The BE and CCK PBMC contents increased significantly with age both in human and rat models. Moreover, polyclonal stimulation induced a…

Severe weight loss associated with cancer continues to be a major cause of morbidity in cases of childhood malignancy. The etiology is not completely understood but is probably multifactorial, including reduced ingestion and altered metabolism of…

Importance: The death of a close relative is associated with an increased mortality risk among the bereaved, but much less is known about the potential association of the death of a sibling in childhood with mortality in this population. Objective:…

Organisms respond to infection with complex adaptations involving bidirectional communication between the immune and neuroendocrine systems. The idea of intercellular communication between the neuroendocrine and immune systems via common signal…

The treatment of severe pain with opioids has thus far been limited by their unwanted central side effects. Recent research promises new approaches, including opioid analgesics acting outside the central nervous system, targeting of opioid…

The opiate-like peptide beta-endorphin and adrenocorticotropin are concomitantly secreted in increased amounts by the adenohypophysis in response to acute stress or long-term adrenalectomy as well as in vitro in response to purified corticotropin…

The timing of the measurement of biological samples (e.g. biomarkers) is not always standardized. Biomarkers are the focus of many recent studies and treatments. The purpose of this study was to determine the timing of the release of beta-endorphin…

Pain is difficult and sometimes frustrating to treat, even though new devices and new approaches have been developed in recent years. Pain varies tremendously from one patient to the next, and there are also some studies suggesting that the intensity…

Bisphosphonates are a unique class of drugs. As a family, they are characterized pharmacologically by their ability to inhibit bone resorption, whereas, pharmacokinetically, they are classified by their similarity in absorption, distribution, and…

Neuropeptides, initially thought to be common features of gut and brain, are only synthesized in immune cells and modulate immune functions. The presence and possible functions of these peptides in immune cells in both physiological or pathological…

CB(2) cannabinoid receptor-selective agonists are promising candidates for the treatment of pain. CB(2) receptor activation inhibits acute, inflammatory, and neuropathic pain responses but does not cause central nervous system (CNS) effects,…

We investigated the contractile mechanisms of action of three putative gastroprokinetic agents (cisapride, metoclopramide, and domperidone) on the linear phase of gastroduodenal emptying of solid meals in six healthy conscious dogs. The spatial and…

Stress is known to either up or down regulate immunity. In this study, mice were subjected to handling combined with rectal temperature measurement (RTM) stress or handling only stress. We investigated whether there were any significant differences…

The history of diphosphonates began with studies of inorganic pyrophosphate. This compound was found to occur in many biological fluids and inhibited the precipitation of calcium phosphates. It also slowed the transformation of amorphous calcium…

Introduction: In certain patients, "directives on the adequacy of therapeutic effort" (DAET) known as advanced care planning are important tools to align medical care to patient's and family's objectives of care. Purpose: To describe characteristics…

Background: Perinatal loss is a traumatic and complex experience that contributes to negative maternal psychological states and adverse outcomes impacting fetal development, maternal-fetal/infant bonding, marital/partner relationships, and child…

ENS consists of a complex network of neurons, organised in several plexuses, which interact by means of numerous neurotransmitters. It is capable of modulating the intestinal motility, exocrine and endocrine secretions, microcirculation and immune…

In rats that were fasted for 2 to 3 days there was a decline in hypothalamic, but not pituitary, beta-endorphin. There was no change in pituitary or hypothalamic adrenocorticotropin content as a result of fasting. Endogenous opiates may be involved…

The focus of neurogastroenterology in Rome II was the enteric nervous system (ENS). To avoid duplication with Rome II, only advances in ENS neurobiology after Rome II are reviewed together with stronger emphasis on interactions of the brain, spinal…

Development of analgesic tolerance and withdrawal-induced pain enhancement present serious difficulties for the use of opioids for pain control. Although neuronal mechanisms to account for these phenomena have been sought for many decades, their…

BACKGROUND: Sampling in the absence of accurate or comprehensive information routinely poses logistical, ethical, and resource allocation challenges in social science, clinical, epidemiological, health service and population health research. These…

The stress system orchestrates brain and body responses to the environment. Cortisol (in humans) or corticosterone (in rodents) are important mediators of the stress system. Their action-in concert-is crucial for individual differences in coping with…

Corticosteroids have potent immunosuppressive and anti-inflammatory effects. Although corticosteroids are an important weapon in the clinical arsenal for treating inflammatory episodes, the mechanisms underlying the actions and regulation of…
