Chest physiotherapy (CPT) is a commonly used technique in mechanically ventilated critically ill patients. This study examines the hemodynamic and metabolic changes associated with CPT and measures the attenuation by two doses of intravenous fentanyl (1.5 micrograms/kg and 3.0 micrograms/kg) on these changes. Heart rate, systolic and mean blood pressures, cardiac output, oxygen consumption (VO2...

Cryptotanshinone (CPT), a natural compound isolated from the plant Salvia miltiorrhiza Bunge, is a potential anticancer agent. However, little is known about its anticancer mechanism. Here, we show that CPT inhibited cancer cell proliferation by arresting cells in G(1)-G(0) phase of the cell cycle. This is associated with the inhibition of cyclin D1 expression and retinoblastoma (Rb) protein ph...

Carnitine palmitoyltransferase I (CPT I) catalyzes the conversion of acyl-CoA to acylcarnitine at the outer mitochondrial membrane and is a key enzyme in the control of long-chain fatty acid (LC-FA) oxidation. Because myocardial LC-FA oxidation increases dramatically after birth, we determined the extent to which CPT I expression contributes to these changes in the perinatal lamb. We measured t...

CPT-11 is a first-line chemotherapeutic agent for the treatment of colorectal cancer in clinic. Previous studies including ours have demonstrated that CPT-11 is, however, toxic to the intestinal epithelium and resident peritoneal macrophages. By interacting with B1 cells, the resident peritoneal macrophages play critical roles in the maintenance of gastrointestinal homeostasis. It remains there...

6-Hydroxymethylacylfulvene (MGI-114) is a semisynthetic analogue of the toxin illudin S, a product of the Omphalotus mushroom. MGI-114 induces cytotoxicity in a variety of solid tumors in vivo, including the refractory HT29 human colon cancer xenograft. In this study, the potential application of MGI-114 in the treatment of colon cancer was further explored by evaluating the activity of MGI-114...

In this paper five members of the “Community Psychoanalytic Track and Consortium” (CPT&C) in San Francisco, California, each holding different positionalities functioning roles, come together dialog with shared aim to bring themselves their readers inside CPT&C. This writing project recapitulates principles CPT&C's vision itself: form polyvocal groups task supporting other our various community...

Camptothecin-l 1 (CPT-11) is a new derivative of camptothecin, a plant alkaloid antitumor agent, and a good candidate for clinical trials because of higher antitumor activity, less toxicity, and high aqueous solubility. CPT-11 is known to be altered into an active form, SN-38, by esterase in in vivo. CPT-11-resistant cells (PC-7/CPT) established from a human nonsmall cell lung cancer cell (PC-7...

BACKGROUND Attentional dysfunction is related to functional disability in patients with neuropsychiatric disorders such as schizophrenia, bipolar disorder, and Alzheimer's disease. Indeed, sustained attention/vigilance is among the leading targets for new medications designed to improve cognition in schizophrenia. Although vigilance is assessed frequently using the continuous performance test (...
