    Notes: Abstract— Of the amino acids found in the CNS of 10-day-old rats the concentration of glycine alone was significantly higher in the spinal cord than in all other regions. Spinal levels of glycine, cystathionine, isoleucine and lysine from 1- and 10-day-old rats did not differ significantly from adult values, whereas the levels of most other amino acids, including GABA, glutamate, glutamine and taurine, were higher in the young animals than in the adults. Aspartate was the only amino acid found in lower concentration in the spinal cord of young animals than in adult animals. These and other observations support the conclusion that glycine is used as an inhibitory transmitter in rat spinal cord early in postnatal life. There was a general decrease in the activity of serine hydroxymethyltransferase and a slight increase in the activity of glycine:2-oxoglutarate aminotransferase in the CNS during development. The activity of neither enzyme correlated on a regional basis with the glycine content. The high level of hydroxymethyltransferase activity in the cerebellum of 10-day-old rats suggests that the activity of this enzyme reflects cell growth rate.

    Notes: Water companies in England and Wales produce reports using environmental performance indicators which have been developed in-house. However, there is no recognised methodology for the development of these indicators, and an analysis of available guidance led to the proposal of an appropriate model. This model was tested by semi-structured interviews of water-company managers, and a questionnaire was completed by managers from other industries. The responses from the interviews supported the inclusive, quality-driven approach advocated by the model, and indicated a need to examine (a) the style of management, (b) the staffing structure in water companies, (c) the connection between environmental management systems and indicator development, (d) types of objectives and targets, and (e) the use of indicators as public-relations tools. The result is a methodology for indicator development which can be applied by managers in industry.

    Notes: The interaction with adhesion molecules expressed by vascular endothelium is the first step in lymphocyte infiltration into tissues. At both cutaneous and mucosal sites interleukin-10 (IL-10), IL-12 and transforming growth factor (TGF)-β are important regulators of chronic inflammatory disease, where cutaneous lymphocyte-associated antigen (CLA) and αE integrin (CD103) may be expressed. Unlike CLA, CD103 is not believed to play a role in tissue-specific homing but may help to retain T cells within epithelial layers. We have previously shown that IL-12 alone can together with an unknown cofactor increase the expression of CLA. Stimulation with streptococcal pyrogenic exotoxin C (SpeC) increased the expression of CD103 by CD8+ but not CD4+ T cells. While IL-12 increased superantigen-stimulated expression of CLA, this cytokine strongly inhibited the CD103 expression, and a combination of IL-12 and TGF-β completely abrogated the induced CD103 expression. Conversely, IL-10 suppressed CLA but increased CD103 expression.These findings indicate that, in addition to suppressing the development of Th1-mediated inflammatory responses, IL-10 may also inhibit the migration of CD8+ T cells into the skin while IL-12 promotes such migration. Thus, the expression of CLA and CD103 may be antagonistically regulated by IL-10 and IL-12, and the balance between these cytokines could influence the T-cell migration of inflammatory cells into epithelial tissues.

    Notes: The association of psoriasis with throat infections by streptococcus pyogenes suggests a potential antigenic target for the T cells that are known to infiltrate dermis and epidermis of psoriatic skin. Streptococcal M protein shares an extensive sequence homology with human epidermal keratins. Keratins 16 (K16) and 17 (K17) are mostly absent from uninvolved skin but are upregulated in psoriatic lesions. There is increasing evidence that CD8+ T cells play an important effector role in psoriasis and M protein-primed T cells may recognize these shared epitopes in skin via molecular mimicry. To identify candidate epitopes, peptides with sequences from K17 were selected on the basis of predicted binding to HLA-Cw6 and sequence similarities with M6 protein. Matched peptides from the sequence of M6 protein and a set of peptides with poor predicted binding were also selected. Cw6+ individuals with psoriasis and Cw6+ healthy controls, having a family history of psoriasis, were recruited. PBMCs were incubated with the peptide antigens. T-cell activation in the CD4+, CD8+ and later the skin-homing cutaneous lymphocyte-associated antigen (CLA)-expressing subset of CD8+ T cells was evaluated by CD69 expression and intracellular IFN-γ accumulation using flow cytometry. We demonstrate that Cw6+ psoriasis patients had significant CD8+ T-cell IFN-γ responses to peptides from K17 and M6 protein selected on the basis of sequence homology and predicted HLA-Cw*0602 binding. These responses were about 10 times more frequent in the skin-homing cutaneous lymphocyte-associated antigen-expressing (CLA+) subset of CD8+ T cells. CD4+ T cells showed only borderline responses. CD8+ T cells from Cw6 + nonpsoriatic individuals responded to some M6 peptides but very rarely to K17 peptides, and this also applied to the CLA+CD8+ subset. These findings indicate that psoriatic individuals have CD8+ T cells that recognize keratin self-antigens and that epitopes shared by streptococcal M protein and human keratin may be targets for the CD8+ T cells that infiltrate psoriatic skin lesions.

    Notes: The amyloid β/A4 protein precursor (APP) has been shown to be implicated in age-associated plastic changes at synapses that might contribute to memory loss in Alzheimer's disease. As APP has previously been reported to have multiple functions during normal development, we have employed a one-trial passive avoidance task in day-old chicks to study its role in the process of memory formation. Administration of anti-APP antibodies, injected 30 min pretraining, prevented memory for a one-trial passive avoidance task in day-old chicks without effects on general behaviour or initial acquisition. Amnesia was apparent by 30 min post-training and lasted for at least 24 h. The same result was obtained by down-regulation of APP expression by APP-antisense, injected 8–12 h pretraining. However, injections of anti-APP antibodies or APP antisense at later post-training time did not cause amnesia for the task. Unlike antibodies and antisense, injection of the APP328–332 pentapeptide, in either orientation, 30 min pretraining, rescued the memory and prevented antisense-induced amnesia. The post-training time within which the antibody- and antisense-induced amnesia, and within which the APP peptides prevent amnesia, correspond to that during which memory formation is vulnerable to disruption of the putative signal transduction functions of APP. These results suggest that: (i) APP is required during an early phase of memory formation, and (ii) the memory enhancing effect of secretory APP is localized within a 5-mer sequence of growth-promoting domain.

    Notes: Summary Intra-arterial measurement is considered the gold standard for continuous, beat-to-beat arterial blood pressure monitoring. However, arterial cannulation can be difficult and may cause complications such as thrombosis and ischaemia. Recently, a tonometric system, the Colin CBM-7000 has been developed for noninvasive beat-to-beat measurement of arterial blood pressure from the radial artery. We assessed the level of agreement between the CBM-7000 and invasive radial artery measurements in 15 patients on a neuro-intensive care unit. Agreement of systolic, diastolic and mean arterial pressure values was limited, with ≈ 34% of mean arterial pressures differing by over 10 mmHg. In many cases, this was due to a downward drift of the noninvasive measurements over time. Furthermore, there was a tendency to underestimate low pressures and overestimate high pressures. In our opinion, the Colin CBM-7000 cannot be recommended for continuous blood pressure monitoring in the intensive care setting.
