Collaboration, facilities and communities in day care services for older people

HEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 1 2001
Sarah Burch BA
Abstract Collaborative working in care for older people is often seen as a desirable goal. However, there can be problems with this approach. This paper reports on a single blind randomized controlled trial which was carried out to compare outcomes of rehabilitation in two settings: a day hospital and social services day centres augmented by visiting therapists. The subjects were 105 older patients. Principal outcome measures were the Barthel Index, Philadelphia Geriatric Centre Morale Scale and the Caregiver Strain Index. Two aspects of the trial are examined here. Firstly, we investigated whether trial patients were more disabled than regular day centre attendees. Levels of health and well being amongst trial patients were compared with those of a random sample of 20 regular attendees from both of the participating day centres and an additional voluntary sector day centre. Secondly, key staff from the different settings were interviewed to assess how well the day centre model had worked in practice. Trial patients were significantly more disabled than regular day centre attendees according to the Barthel Index (P < 0.001), but this difference was no longer significant after three months of treatment. The day centre model had several problems, principally discharge policy, acceptability, facilities and attitudes of staff and regular attendees. Positive aspects of the day centre model, as well as successful rehabilitation, included shared skills, knowledge and resources. This paper suggests that collaborative working in day centres requires multipurpose facilities. If health staff maintain a permanent presence, benefits can include improved joint working, easier access to health care and the use of rehabilitative therapy as a preventative strategy. Day care settings can be analyzed as representing different types of communities. Allowing older users a greater degree of choice in facilities may increase the acceptability of care. [source]


A novel inducible tyrosine kinase receptor to regulate signal transduction and neurite outgrowth

JOURNAL OF NEUROSCIENCE RESEARCH, Issue 12 2009
Ronald W. Alfa
Abstract Nervous system growth factor gene delivery can promote axonal growth and prevent cell death in animal models of CNS trauma and neurodegenerative diseases. The ability to regulate growth factor expression or signaling pathways downstream from growth factor receptors remains a desirable goal for in vivo gene transfer. To achieve precise pharmacological modulation of neurotrophin activity, we have generated a chimeric trkA receptor (ItrkA) by fusing the entire intracellular domain of the trkA high-affinity NGF receptor to two intracellular, modified FK506 binding domains for the synthetic small molecule dimerization ligand AP20187. Rat PC12 cells were transduced with lentiviral vectors containing ItrkA and green fluorescent protein (GFP; via an internal ribosome entry site). Treatment of ItrkA-expressing PC12 cells with AP20187 induced neurite outgrowth and differentiation in a time- and dose-dependent fashion, with a half-maximal response at a concentration of 1 nM AP20187. Seventy percent of cells responded to AP20187 by day 3. Western blots demonstrated that AP20187 treatment resulted in phosphorylation of Erk1/2 and Akt in ItrkA-transduced PC12 cells but not in nontransduced, naïve cells. Phosphorylation levels were comparable to levels obtained with 50 ng/ml nerve growth factor (NGF). In addition, ItrkA lentiviral transduction of primary E15 dorsal root ganglion neurons significantly increased neurite growth three- to fourfold in the presence of AP20187 compared with control GFP transduced and naïve neurons. These results demonstrate that small ligand-induced dimerization of the intracellular domain of trkA can efficiently simulate the biological activity of NGF and provide a means to regulate intracellular neurotrophin receptor signaling. © 2009 Wiley-Liss, Inc.

Osman and police immunity in the English law of torts

LEGAL STUDIES, Issue 3 2000
Paula Giliker
This article examines and questions the nature of police immunity from claims for negligence in the investigation and suppression of crime, as stated by the House of Lords in Hill v Chief Constable of West Yorkshire. This issue has been discussed before the European Court of Human Rights in Osman v United Kingdom, where the court held that a blanket application of the immunity was contrary to art 6 of the European Convention on Human Rights. This article will argue that this decision does not overturn the basic public policy principles for the immunity stated in Hill and that further examination of this area of law is required. It is submitted that if the law is considered in terms of proximity rather than in terms of public policy immunity, a clearer understanding of the principles underlying this area of law can be reached together with the desirable goal of removing the term ,immunity' from this area of law.

Differences in lymphocyte gene expression between tolerant and syngeneic liver grafted rats

LIVER TRANSPLANTATION, Issue 3 2004
Masayuki Fujino
Induction of tolerance to allogeneic donor grafts is a clinically desirable goal in bone marrow and solid organ transplantation. We have taken the advantage of DNA microarray technology to investigate gene expression mechanism in regulatory cells. In the present study, using a tacrolimus (FK506) induced tolerance of the fully mismatched liver allograft rat model, we demonstrated that, in contrast with peripheral blood lymphocytes (PBLs) from syngeneic recipients, PBLs taken from tolerant recipients 100 days after transplantation were able to suppress the in vitro proliferation of allogeneic PBLs and to prolong the survival of second syngeneic recipients. We also compared messenger RNA profiles in PBLs from tolerant recipients with those from syngeneic recipients using a DNA microarray with probe sets corresponding to more than 8000 rat genes. There were 96 up-regulated and 103 down-regulated genes in the tolerant recipients. In the up-regulated group, there were 76 known genes and 20 expressed sequence tags (ESTs). In the down-regulated groups, there were 87 known genes and 16 ESTs. Our data indicated that FK506 treatment induced tolerance and expansion of regulatory cells and the DNA microarray technology was useful for this application and provided many informative insights into the mechanism of lymphocyte regulation.

Reactivity of Intein Thioesters: Appending a Functional Group to a Protein

CHEMBIOCHEM, Issue 9 2006
Jeet Kalia
Abstract The success of genome sequencing has heightened the demand for new means to manipulate proteins. An especially desirable goal is the ability to modify a target protein at a specific site with a functional group of orthogonal reactivity. Here, we achieve that goal by exploiting the intrinsic electrophilicity of the thioester intermediate formed during intein-mediated protein splicing. Detailed kinetic analyses of the reaction of nitrogen nucleophiles with a chromogenic small-molecule thioester revealed that the ,-hydrazino acetyl group was the optimal nucleophile for attacking a thioester at neutral pH to form a stable linkage. A bifunctional reagent bearing an ,-hydrazino acetamido and azido group was synthesized in high overall yield. This reagent was used to attack the thioester linkage between a target protein and intein, and thereby append an azido group to the target protein in a single step. The azido protein retained full biological activity. Furthermore, its azido group was available for chemical modification by Huisgen 1,3-dipolar azide,alkyne cycloaddition. Thus, the mechanism of intein-mediated protein splicing provides the means to install a useful functional group at a specific site,the C terminus,of virtually any protein. [source]
