Pharmacological and philosophical considerations for the around-the-clock use of scheduled melatonin to promote sedation and reduce aggression in individuals with serious mental illness: a case report.

Melatonin, the endogenous hormone that helps maintain circadian rhythm, has been used exogenously for both primary and secondary sleep disorders. While the effects of melatonin given prior to planned sleep and to restore normal circadian sleep phases have been well studied, there is little information on the use of melatonin as a pharmacotherapeutic intervention for around-the-clock sedation to prevent agitation and aggressive patient behaviors. This is the first case report to our knowledge of melatonin used throughout the day, as a scheduled dose for prolonged treatment duration, to reduce aggression in a patient with severe mental illness.

Contribution of mucus concentration and secreted mucins Muc5ac and Muc5b to the pathogenesis of muco-obstructive lung disease.

Airway diseases, including cigarette smoke-induced chronic bronchitis, cystic fibrosis, and primary ciliary dyskinesia are associated with decreased mucociliary clearance (MCC). However, it is not known whether a simple reduction in MCC or concentration-dependent mucus adhesion to airway surfaces dominates disease pathogenesis or whether decreasing the concentration of secreted mucins may be therapeutic. To address these questions, Scnn1b-Tg mice, which exhibit airway mucus dehydration/adhesion, were compared and crossed with Muc5b- and Muc5ac-deficient mice.

Adjunct Histamine Blockers as Premedications to Prevent Carboplatin Hypersensitivity Reactions.

Objective: The objective of this study was to evaluate the impact of premedications given as an adjunct to carboplatin on the incidence of hypersensitivity reactions in women with ovarian cancer. Medications of interest include a histamine1 (H1 ) and histamine2 (H2 ) blocker in addition to dexamethasone.

Methods: This was a retrospective chart review evaluating the addition of an H1 and H2 blocker in addition to dexamethasone as standard premedications on the incidence of carboplatin hypersensitivity reactions (CHRs) in women with ovarian cancer.

Evaluation of intervention to prevent hypomagnesemia in cervical cancer patients receiving combination cisplatin and radiation treatment.

Purpose: The purpose of this study was to evaluate the impact of increasing the magnesium (Mg(2+)) supplementation in the pre- and posthydration of patients receiving cisplatin plus radiation (CisXRT) to prevent chemotherapy-induced hypomagnesemia (CIH) events.

Materials And Methods: The study was conducted on newly diagnosed cervical cancer patients receiving CisXRT. The first prospective intervention to prevent CIH was to increase the pre- and posthydration Mg(2+) from 1 to 2 g.

What women with ovarian cancer think and know about genetic testing.

Objectives: Few women with ovarian cancer undergo genetic testing for the Breast and Ovarian Cancer susceptibility genes, BRCA1 and BRCA2. With the prospect of BRCA-directed therapeutics, we investigated ovarian cancer patients' knowledge and willingness to undergo genetic testing.

Methods: All ovarian cancer patients seen in the Gynecology Center of a cancer center and a private clinic were asked to complete an anonymous questionnaire regarding knowledge and willingness to undergo BRCA testing.

Evaluating patients with mildly elevated transaminase levels.

S.B. is a 52-year-old woman with recurrent stage IV ovarian cancer.

Intracellular trafficking of interleukin-1 receptor I requires Tollip.

Interleukin-1 receptor (IL-1RI) is a master regulator of inflammation and innate immunity. When triggered by IL-1beta, IL-1RI aggregates with IL-1R-associated protein (IL-1RAcP) and forms a membrane proximal signalosome that potently activates downstream signaling cascades. IL-1beta also rapidly triggers endocytosis of IL-1RI.

Tollip regulates proinflammatory responses to interleukin-1 and lipopolysaccharide.

Activation of interleukin-1 (IL-1) receptor (IL-1R), Toll-like receptor 2 (TLR2), and TLR4 triggers NF-kappaB and mitogen-activated protein kinase (MAPK)-dependent signaling, thereby initiating immune responses. Tollip has been implicated as a negative regulator of NF-kappaB signaling triggered by these receptors in in vitro studies. Here, deficient mice were used to determine the physiological contribution of Tollip to immunity.

Inflammatory diseases: is ubiquitinated NEMO at the hub?

Many patients with Crohn's disease carry mutations in NOD2, a molecule that can both activate and attenuate the pro-inflammatory effects of NF-kappa B. Recent studies implicate NOD2-induced ubiquitination of the NF-kappa B regulator NEMO as a potential means of manipulating the NF-kappa B signal.

NALP3 forms an IL-1beta-processing inflammasome with increased activity in Muckle-Wells autoinflammatory disorder.

Mutations within the NALP3/cryopyrin/CIAS1 gene are responsible for three autoinflammatory disorders: Muckle-Wells syndrome, familial cold autoinflammatory syndrome, and CINCA. The NALP3 protein is homologous to NALP1, which is a component of the inflammasome, a molecular platform that activates the proinflammatory caspases-1 and -5. NALP3 (and other members of the NALP family) lacks the C-terminal, CARD-containing sequence of NALP1, and its role in caspase activation is unclear.

Ubiquitination of the Epstein-Barr virus-encoded latent membrane protein 1 depends on the integrity of the TRAF binding site.

The latent membrane protein 1 (LMP1) encoded by the Epstein-Barr virus functions as a constitutively activated receptor of the tumor necrosis factor receptor family. LMP1 is a short-lived protein that is ubiquitinated and degraded by the proteasome. We have previously shown that LMP1 recruits the adapter protein tumor necrosis factor receptor-associated factor 3 (TRAF3) to lipid rafts.

NALPs: a novel protein family involved in inflammation.

A newly discovered family of cytoplasmic proteins--the NALPs--has been implicated in the activation of caspase-1 by the Toll-like receptors (TLRs) during the cell's response to microbial infection. Like the structurally related apoptotic protease-activating factor-1 (APAF-1), which is responsible for the activation of caspase-9, the NALP1 protein forms a large, signal-induced multiprotein complex, the inflammasome, resulting in the activation of pro-inflammatory caspases.

Inhibition of interleukin 1 receptor/Toll-like receptor signaling through the alternatively spliced, short form of MyD88 is due to its failure to recruit IRAK-4.

Toll-like receptors (TLRs) and members of the proinflammatory interleukin 1 receptor (IL-1R) family are dependent on the presence of MyD88 for efficient signal transduction. The bipartite nature of MyD88 (N-terminal death domain [DD] and COOH-terminal Toll/IL-1 receptor [TIR] domain) allows it to link the TIR domain of IL-1R/TLR with the DD of the Ser/Thr kinase termed IL-1R-associated kinase (IRAK)-1. This triggers IRAK-1 phosphorylation and in turn the activation of multiple signaling cascades such as activation of the transcription factor nuclear factor (NF)-kappaB.

The inflammasome: a molecular platform triggering activation of inflammatory caspases and processing of proIL-beta.

Generation of Interleukin (IL)-1beta via cleavage of its proform requires the activity of caspase-1 (and caspase-11 in mice), but the mechanism involved in the activation of the proinflammatory caspases remains elusive. Here we report the identification of a caspase-activating complex that we call the inflammasome. The inflammasome comprises caspase-1, caspase-5, Pycard/Asc, and NALP1, a Pyrin domain-containing protein sharing structural homology with NODs.

Patterns of epithelial cell invasion by different species of the Burkholderia cepacia complex in well-differentiated human airway epithelia.

Burkholderia cepacia has emerged as a serious respiratory pathogen in cystic fibrosis (CF) patients. The clinical course of B. cepacia infections is variable, but approximately 20% of patients eventually succumb to the cepacia syndrome, which is characterized as a fatal necrotizing pneumonia with bacteremia.
