We have previously shown that interleukin-1 (IL-1), a polypeptide known to mediate many aspects of the acute phase response to infection, suppresses food intake when injected intraperitoneally into fasted rats. IL-1 acts at the level of the hypothalamus to induce fever. In view of the large number of peptides that have been shown to alter food intake as(More)
Cancer patients frequently suffer from fatigue, a complex syndrome associated with tiredness and depressed mood. Cancer-related fatigue (CRF) can be present at the time of diagnosis, escalates during treatment, and can persist for years after treatment. CRF negatively influences quality of life, limits functional independence, and is associated with(More)
The influence of academic examinations on immunity and lung function was investigated in 64 adolescents to determine if stress-related changes would differ between healthy and asthmatic students. Blood samples were collected on three occasions: 1 month prior, during, and 2-3 weeks after exams. Leukocyte subsets were enumerated, and in vitro assays were(More)
Anorexia is a common response to infection which is thought to be mediated, at least in part, by interleukin (IL-1), an immunoregulatory peptide secreted by activated monocytes. Cholecystokinin (CCK) is a neuropeptide that suppresses food intake and gastric emptying when injected into healthy animals. There is increasing evidence of bidirectional(More)
The Bcl-2 family of proteins plays a critical role in controlling immune responses by regulating the expansion and contraction of activated lymphocyte clones by apoptosis. ABT-737, which was originally developed for oncology, is a potent inhibitor of Bcl-2, Bcl-x(L), and Bcl-w protein function. There is evidence that Bcl-2-associated dysregulation of(More)
AIMS Fatigue is a common occurrence in cancer patients regardless of tumor type or anti-tumor therapies and is an especially problematic symptom in persons with incurable tumor disease. In rodents, tumor-induced fatigue is associated with a progressive loss of skeletal muscle mass and increased expression of biomarkers of muscle protein degradation. The(More)
Chronic prenatal stress contributes to poor birth outcomes for women and infants. Importantly, poor birth outcomes are most common among minority and low income women. To investigate underlying mechanisms, we tested the hypothesis that chronic stress related to minority or low income status is associated with glucocorticoid resistance as indicated by(More)
Cancer patients frequently suffer from fatigue, a complex syndrome associated with loss of muscle mass, weakness, and depressed mood. Cancer-related fatigue (CRF) can be present at the time of diagnosis, during treatment, and persists for years after treatment. CRF negatively influences quality of life, limits functional independence, and is associated with(More)
Interleukin-1 is a small molecular weight peptide that is thought to mediate much of the acute phase response to infection, including fever and anorexia and gastric stasis. In the present study, we examined the effects of recombinant human IL-1 alpha (rhIL-1a) on food intake and gastric emptying, and the role of prostaglandins (PG) in IL-1 induced(More)
OBJECTIVE To determine whether labor-associated inflammatory markers differ between low-risk, nulliparous women in preactive vs active labor at hospital admission and over time. STUDY DESIGN Prospective comparative study of low-risk, nulliparous women with spontaneous labor onset at term (n = 118) sampled from 2 large Midwestern hospitals. Circulating(More)
