Validity of using the Assessment of Motor and Process Skills to estimate overall home safety in persons with psychiatric conditions.

Objective: Occupational therapists often base estimates of home safety on their behavioral observations of a client performing functional activities during a hospitalization. To examine this practice, this study investigated the predictive validity of the Assessment of Motor and Process Skills (AMPS) to the overall home safety of persons with psychiatric conditions associated with cognitive impairments.

Method: Ability in activities of daily living (ADL) of 20 participants was evaluated with the AMPS before discharge from an inpatient psychiatric unit.

Adolescent health spending and measures in state Title V Maternal and Child Health Programs.

This study examines how state public health agencies report using Title V Maternal and Child Health Block Grant funds to improve the health of adolescents. The Title V Information System was analyzed to identify state level expenditures allocated to pediatric primary and preventive care and to identify measures that monitor adolescents' primary and preventive health care as defined by adolescent clinical preventive guidelines such as Bright Futures and Guidelines for Adolescent Preventive Services. Most states do not report expending 30 percent or more on primary and preventive care, nor do they report measuring adolescents' receipt of primary or preventive health services.

Pharmacokinetics and tissue distribution of the nonadecapeptide Moli1901 in rats and mice.

1. Administration of aerosolized, radiolabelled Moli1901 (duramycin, 2622U90), a 19 amino acid polycyclic peptide, to rats resulted in the deposition of high amounts of radiolabel in the respiratory tract, with deposited radiolabel persisting almost unchanged through 7 days after dosing. Little to no radiolabel was present in the bloodstream of these rats.

New graduate RNs in a float pool. An inner-city hospital experience.

Nurse managers and nurse educators alike have historically discouraged hiring new graduate RNs into a float pool and have preferred experienced nurses with multiple clinical skills. With a nursing shortage and changing marketplace, we need different strategies for recruitment and retention and ways to improve our clinical practice. A new graduate RN offers a nursing service an opportunity to employ a motivated, ready-to-learn, educationally prepared and intellectually stimulated nurse who happens to have limited clinical experience.

Evidence that a copper-metallothionein complex is responsible for fluorescence in acid-secreting cells of the Drosophila stomach.

Copper cells were originally identified in Drosophila midgut epithelium by their striking orange fluorescence in copper-fed larvae. Here, we examined copper cell fluorescence in light of the previous observations that (1) a similar fluorescent signal in yeast is produced by a complex between copper and metallothionein, and (2) metallothionein is expressed constitutively in the copper cell region and inducibly in other regions of the Drosophila midgut. Pulse-feeding experiments with 1 mM CuCl2 revealed that fluorescence appeared rapidly in copper cells (<5 min) and slowly in other cells of the midgut (days), suggesting a constitutive cofactor in the former and an inducible cofactor in the latter.

Characterisation of a chicken anaemia virus variant population that resists neutralisation with a group-specific monoclonal antibody.

A variant population of chicken anaemia virus (CAV), termed P310 2A9-resist, that resists neutralisation by the monoclonal antibody (MAb) 2A9, was selected from Cux-1 virus that had been passaged 310 times (P310) in MDCC-MSB1 cells. Substantially higher concentrations of MAb 2A9 were required to neutralise the selected virus compared to those required to neutralise a low-passage (P13) Cux-1 isolate. Virus neutralisation tests showed that serum from chickens infected with the P310 2A9-resist virus neutralised P13 virus and that serum from chickens infected with P13 virus conversely neutralised the P310 2A9-resist virus.

Effect of tourniquet pressure and intra-individual variability on plasma fibrinogen, platelet P-selectin and monocyte tissue factor.

Small differences in levels of certain haemostatic components may be clinically significant. It is important therefore to eliminate potential sources of confounding variability. This study investigated the effect of removing tourniquet pressure prior to sample collection on plasma fibrinogen levels, platelet P-selectin and monocyte tissue factor expression.

Effect of parainfluenza-3 virus challenge on cell-mediated immune function in parainfluenza-3 vaccinated and non-vaccinated calves.

A group of four conventional, colostrum-fed calves was vaccinated with live parainfluenza type 3 (PI-3) virus vaccine at 1 and 5 weeks of age. A group of four control calves was treated with cell culture medium at the same time. Two weeks after the second vaccination, both groups of calves were challenged with PI-3 virus by a combined respiratory route.

Pharmacokinetics and hematological effects of the PEGylated thrombopoietin peptide mimetic GW395058 in rats and monkeys after intravenous or subcutaneous administration.

GW395058, a potent PEGylated peptide human thrombopoietin receptor (HuTPOr) agonist in vitro, is being evaluated for the treatment of thrombocytopenia. GW395058 shares no sequence homology with TPO. In this report the pharmacokinetics and hematological effects of GW395058 in rats and monkeys are described.

Antigenicity and pathogenicity characteristics of molecularly cloned chicken anaemia virus isolates obtained after multiple cell culture passages.

The Cux-1 isolate of chicken anaemia virus (CAV), which had received 310 (P310) cell culture passages, was substantially less pathogenic than virus that had been passaged 13 times (P13). Molecularly cloned virus isolates, selected from the P310 and P13 virus populations using recombinant DNA cloning and transfection procedures, reacted differently with 4 CAV-specific monoclonal antibodies (MAbs), which had been raised to low-passage Cux-1 virus. In contrast to the strong immunofluorescence (IF) reactivities exhibited by all P13 cloned isolates tested, 80% and 57% of the P310 cloned isolates reacted weakly with MAbs 2A9 and 4H4, which are directed against conformational epitopes on the capsid protein, VP1.

Studies on the efficacy of intranasal vaccination for the prevention of experimentally induced parainfluenza type 3 virus pneumonia in calves.

The efficacy of intranasal vaccination in preventing or limiting disease of the lower respiratory tract induced by parainfluenza 3 (PI3) virus was evaluated under experimental conditions, using a commercially available live vaccine containing a temperature-sensitive strain of PI3 virus. In a preliminary study four colostrum-deprived calves were vaccinated intranasally at one week and again at two months of age, and two similar calves were given an intranasal placebo. After the second vaccination serum antibodies to PI3 virus were detected in all four vaccinated calves, but not in the control animals.

Access to medical care for adolescents: results from the 1997 Commonwealth Fund Survey of the Health of Adolescent Girls.

Purpose: This study examined the factors associated with access to care among adolescents, including gender, insurance coverage, and having a regular source of health care.

Methods: Analyses were done on the 1997 Commonwealth Fund Survey of the Health of Adolescent Girls, a nationally representative sample of in-school adolescents in 5th through 12th grade. Access to health care, missing needed care, and whether the adolescent had private time with their provider were assessed.

Vascular surgical society of great britain and ireland: contribution of malnutrition to postoperative morbidity in vascular surgical patients.

BACKGROUND: In an elderly population of surgical patients, poor mobility, poor diet and chronic disease contribute to a significant risk of malnutrition. Malnutrition is associated with muscle weakness, fatigue, poor wound healing and immunological dysfunction. The aim of the study was to establish the prevalence of malnutrition in vascular surgical patients and to compare postoperative infection rates in well nourished and malnourished patients.

Cytotoxic interactions between bovine parainfluenza type 3 virus and bovine alveolar macrophages.

This paper describes an investigation of the cytotoxic activity of bovine alveolar macrophages for parainfluenza type 3 (PI-3) virus-infected target cells, using 51Cr release assays. Alveolar macrophages from uninfected calves were shown to be capable of killing PI-3 virus infected cells without the presence of antibody or complement (antibody-independent cell-mediated cytotoxicity). The level of killing was shown to vary from animal to animal with specific lysis values ranging from <5% to 70%.

Adolescents' access to care: teenagers' self-reported use of services and perceived access to confidential care.

Background: Most surveys on adolescents' use of health services rely on parental report, and this may underestimate adolescents' use of confidential services.

Objective: To investigate adolescents' report of their own use of health services, access to care, and knowledge and use of confidential services.

Method: A random digit-dialed survey of 14- to 19-year-old adolescents was conducted in Monroe County, New York.

Investigation of the attenuation exhibited by a molecularly cloned chicken anemia virus isolate by utilizing a chimeric virus approach.

Molecular cloning of the Cux-1 isolate of chicken anemia virus (CAV), which had been passaged 173 times in cell culture, resulted in the isolation of an attenuated strain, designated cloned isolate 10, which reverted to virulence following 10 passages in young chicks (D. Todd, T. J.

Gordon Memorial Lecture. Chicken anaemia virus--a glimpse of the future?

This paper uses background information about chicken anaemia virus as a guide to how the study and control of virus diseases of poultry may develop in the future. It is predicted that "new' viruses will be discovered in poultry, many of which will be difficult to grow in vitro and whose pathogenicity may appear uncertain. When new diseases/syndromes arise in the future, it should be a priority activity to define their pathology.

Sequence of porcine circovirus DNA: affinities with plant circoviruses.

The complete nucleotide sequence (1759 nt) of the ssDNA genome of porcine circovirus (PCV) was determined from a cloned dsDNA replicative form isolated from PCV-infected cells. Sequence analysis detected no significant nucleic acid or protein similarity with another animal circovirus, chicken anaemia virus (CAV) but, surprisingly, the highest protein similarity was obtained between the product of the largest predicted PCV ORF (ORF1; encoding a potential protein of 35.7 kDa) and a putative protein encoded by the plant circovirus banana bunchy top virus (BBTV).

Bovine adenovirus type 10: properties of viruses isolated from cases of bovine haemorrhagic enterocolitis.

The isolation, serological classification and growth properties of adenoviruses isolated from fatal cases of haemorrhagic enterocolitis in calves are described. Four viruses, from different submissions, were isolated in cultures of calf testis cells and were identified as adenoviruses by electron microscopy. The four isolates were serologically identical and were classified as bovine adenovirus type 10 in cross-neutralisation tests with other bovine, ovine and porcine adenovirus species.

Development of a novel scintillation proximity competitive hybridization assay for the determination of phosphorothioate antisense oligonucleotide plasma concentrations in a toxicokinetic study.

A novel scintillation proximity competitive hybridization assay was developed for determining plasma concentrations of compound 4003W94, a 15-base phosphorothioate antisense deoxyribonucleotide that is currently under preclinical evaluation for the treatment of restenosis following coronary artery angioplasty. The principle of the assay involves the hybridization binding of antisense (4003W94) to a biotinylated sense oligonucleotide to form a double-stranded nucleic acid complex on the surface of scintillation proximity beads derivatized with streptavidin. As in a competitive radioimmunoassay, there is an inverse relationship between the amount of radioactivity in the final binding complex and the amount of 4003W94 present in the sample being analyzed.

Investigation of the transfection capability of cloned tandemly-repeated chicken anaemia virus DNA fragments.

Chicken anaemia virus (CAV) is an icosahedral virus, 25 nm in diameter, which, on the basis of its circular single-stranded DNA genome, has recently been classified in the family, Circoviridae. We have investigated whether infectious, monomeric CAV DNA from recombinant plasmids containing tandemly-repeated CAV replicative form (RF) DNAs, following transfection, was generated by homologous recombination or a replicational release mechanism involving rolling circle replication (RCR) of DNA. Experiments designed to locate the virus strand origin of RCR and/or sites of recombination were performed by sequence analyses of hybrid viruses generated after transfection with cloned tandemly-repeated RFs specified by the sequence-distinct Cux-1 and 26P4 isolates.
