What evidence exists on the ecological and physical effects of built structures in shallow, tropical coral reefs? A systematic map protocol.

Background: Shallow, tropical coral reefs face compounding threats from habitat degradation due to coastal development and pollution, impacts from storms and sea-level rise, and pulse disturbances like blast fishing, mining, dredging, and ship groundings that reduce coral reefs' height and variability. One approach toward restoring coral reef structure from these threats is deploying built structures. Built structures range from engineered modules and repurposed materials to underwater sculptures and intentionally placed natural rocks.

Pharmacy work: Intrinsic motivation and extrinsic rewards across role and setting.

Background: Pharmacists' and pharmacy technicians' stress and job turnover are at an all-time high. Both intrinsic motivations and extrinsic rewards play key roles in workplace satisfaction. Differences in workplace satisfaction have been identified when comparing chain pharmacies, independent pharmacies, and health systems work settings.

Status shields and pharmacy work: Differences among workers by role and context.

Status and workplace context directly affect employee experiences at work. This study looks at an understudied essential health professional group: pharmacy workers. Using survey data from 298 pharmacy workers in the United States we test how status, status shields, and work context relate to perceptions of one's work.

The Structuration of Community-Based Mental Health Care: A Duality Analysis of a Volunteer Group's Local Agency.

Using a lens of structuration theory, this study highlights the ways that specific structures within the current community-based model of mental health care might enable and constrain individuals and families living with mental illness. Through a case study of a volunteer mental illness advocacy group, the authors employed a duality analysis on a variety of data collected from the case (i.e.

Postnatal Phencyclidine (PCP) as a Neurodevelopmental Animal Model of Schizophrenia Pathophysiology and Symptomatology: A Review.

Cognitive dysfunction and negative symptoms of schizophrenia remain an unmet clinical need. Therefore, it is essential that new treatments and approaches are developed to recover the cognitive and social impairments that are seen in patients with schizophrenia. These may only be discovered through the use of carefully validated, aetiologically relevant and translational animal models.

Assessment of disease-related cognitive impairments using the novel object recognition (NOR) task in rodents.

The novel object recognition test (NOR) test is a two trial cognitive paradigm that assesses recognition memory. Recognition memory is disturbed in a range of human disorders and NOR is widely used in rodents for investigating deficits in a variety of animal models of human conditions where cognition is impaired. It possesses several advantages over more complex tasks that involve lengthy training procedures and/or food or water deprivation.

The involvement of distraction in memory deficits induced by NMDAR antagonism: relevance to cognitive deficits in schizophrenia.

Recognition memory, impaired in neuropsychiatric conditions and currently untreated, may be assessed by the novel object recognition (NOR) task with robust impairments induced by sub-chronic treatment with the N-methyl-d-aspartate receptor antagonist phencyclidine (PCP). The aim of the present study was to investigate how sub-chronic PCP produces its effects in this task. Forty adult female rats received vehicle or PCP (2mg/kg i.

Obstetric cholestasis, outcome with active management: a series of 70 cases.

Objective: To determine the nature and outcome of obstetric cholestasis in a United Kingdom population.

Design: Prospective analysis of clinical outcome in women diagnosed with obstetric cholestasis that is actively managed.

Setting: Antenatal population of three London hospitals between August 1999 and April 2001.

Pruritus may precede abnormal liver function tests in pregnant women with obstetric cholestasis: a longitudinal analysis.

Obstetric cholestasis is a liver disorder unique to pregnancy, which typically presents with pruritus. However, pruritus is common in pregnancy and the diagnosis of obstetric cholestasis is confirmed by finding abnormal liver function. We report 10 cases in which pruritus occurred before any abnormality in liver function tests (including total serum bile acids) and discuss the implications of this for clinical practice.

A high-resolution radiation hybrid map of the human genome draft sequence.

We have constructed a physical map of the human genome by using a panel of 90 whole-genome radiation hybrids (the TNG panel) in conjunction with 40,322 sequence-tagged sites (STSs) derived from random genomic sequences as well as expressed sequences. Of 36,678 STSs on the TNG radiation hybrid map, only 3604 (9.8%) were absent from the unassembled draft sequence of the human genome.

Antibodies to CD44 and integrin alpha4, but not L-selectin, prevent central nervous system inflammation and experimental encephalomyelitis by blocking secondary leukocyte recruitment.

The role of various adhesion molecules in lymphocyte homing to the brain and in inflammatory autoimmune disease of the central nervous system (CNS) was examined in mice. Activated T cell lines and clones expressed CD44 and integrin alpha4, but not L-selectin, and entered the CNS independent of their antigen specificity. mAbs directed against CD44 and integrin alpha4 prevented the transfer of experimental autoimmune encephalomyelitis (EAE) by myelin basic protein-specific T cells.

Relaxin induces an extracellular matrix-degrading phenotype in human lung fibroblasts in vitro and inhibits lung fibrosis in a murine model in vivo.

Pulmonary fibrosis is the common end stage of a number of pneumopathies. In this study, we examined the ability of the human cytokine, relaxin, to block extracellular matrix deposition by human lung fibroblasts in vitro, and to inhibit lung fibrosis in a bleomycin-induced murine model. In vitro, relaxin (1-100 ng/ml) inhibited the transforming growth factor-beta-mediated over-expression of interstitial collagen types I and III by human lung fibroblasts by up to 45% in a dose-dependent manner.

Treatment of experimental encephalomyelitis with a peptide analogue of myelin basic protein.

Following induction of experimental encephalomyelitis with a T-cell clone, L10C1, that is specific for the myelin basic protein epitope p87-99, the inflammatory infiltrate in the central nervous system contains a diverse collection of T cells with heterogeneous receptors. We show here that when clone L10C1 is tolerized in vivo with an analogue of p87-99, established paralysis is reversed, inflammatory infiltrates regress, and the heterogeneous T-cell infiltrate disappears from the brain, with only the T-cell clones that incited disease remaining in the original lesions. We found that antibody raised against interleukin-4 reversed the tolerance induced by the altered peptide ligand.

Insulin-like growth factor-I promotes successful fetal pancreas transplantation in the intramuscular site.

Background: Fetal pancreas (FP) has the capacity for exuberant proliferation and engrafts in the safe, accessible intramuscular site. These characteristics make FP transplantation an attractive approach to the treatment of diabetes mellitus. Insulin-like growth factor-I (IGF-I) is an important mediator of growth and maturation of many tissues and has been shown to induce fetal islet proliferation.

Phase 1 clinical trial of chimeric monoclonal anti-CD4 antibody in multiple sclerosis.

We conducted an open trial of cM-T412, a chimeric monoclonal anti-CD4 antibody, in 29 patients with MS. This antibody caused a prompt and long-lasting depletion of circulating CD4 (helper/inducer) lymphocytes. The mean (+/- SE) CD4 count for the group decreased from 870 (+/- 66) cells/mm3 at baseline to 76 (+/- 11) 3 hours after treatment, and then increased to 425 (+/- 38) at 1 month after treatment and 475 (+/- 39) at 6 months after treatment.

Induction of relapsing paralysis in experimental autoimmune encephalomyelitis by bacterial superantigen.

The role of infection in the pathogenesis of clinical relapses that occur in most autoimmune diseases, including multiple sclerosis, remains to be established. Experimental autoimmune encephalomyelitis (EAE) serves as a model for multiple sclerosis, with episodes of relapsing paralysis. In certain strains of mice, T-lymphocytes expressing the V beta 8 T-cell receptor (TCR) engage the amino-terminal epitope Ac1-11 of myelin basic protein, leading to EAE.
