Abstract
Nine structurally modified apelin-13 analogues were assessed for their in vitro and acute in vivo antidiabetic potential. Stability was assessed in mouse plasma and insulinotropic efficacy tested in cultured pancreatic BRIN-BD11 cells and isolated mouse pancreatic islets. Intracellular Ca2+ and cAMP production in BRIN-BD11 cells was determined, as was glucose uptake in 3T3-L1 adipocytes. Acute antihyperglycemic effects of apelin analogues were assessed following i.p. glucose tolerance tests (ipGGT, 18 mmol/kg) in normal and diet-induced-obese (DIO) mice and on food intake in normal mice. Apelin analogues all showed enhanced in vitro stability (up to 5.8-fold, t½ = 12.8 h) in mouse plasma compared to native apelin-13 (t½ = 2.1 h). Compared to glucose controls, stable analogues exhibited enhanced insulinotropic responses from BRIN-BD11 cells (up to 4.7-fold, p < 0.001) and isolated mouse islets (up to 5.3-fold) for 10-7 M apelin-13 amide (versus 7.6-fold for 10-7 M GLP-1). Activation of APJ receptors on BRIN-BD11 cells increased intracellular Ca2+ (up to 3.0-fold, p < 0.001) and cAMP (up to 1.7-fold, p < 0.01). Acute ipGTT showed improved insulinotropic and glucose disposal responses in normal and DIO mice (p < 0.05 and p < 0.01, respectively). Apelin-13 amide and (pGlu)apelin-13 amide were the most effective analogues exhibiting acute, dose-dependent and persistent biological actions. Both analogues stimulated insulin-independent glucose uptake by differentiated adipocytes (2.9-3.3-fold, p < 0.05) and inhibited food intake (26-33%, p < 0.001), up to 180 min in mice, versus saline. In contrast, (Ala13)apelin-13 and (Val13)apelin-13 inhibited insulin secretion, suppressed beta-cell signal transduction and stimulated food intake in mice. Thus, stable analogues of apelin-13 have potential for diabetes/obesity therapy.

Abstract
Depression remains a significant public health issue globally; 121 million people are affected by depression health education campaigns. Regardless of the prevalence of depression and recent health education campaigns to reduce the burden of depression, many people are still stigmatized and sometimes excluded from the society in which they live. Using qualitative research, the aim of this study was to explore lay people's perceptions and attitudes of mental disorder and in particular depression. A purposive sample of 22 lay people were each asked to read a case scenario which was then followed up by the researcher using open-ended questions to explore their knowledge and attitudes and beliefs relating to depression. The data was analysed using Braun & Clarke's strategy of thematic analysis. The results revealed that many of the participants were familiar with the concept of depression, either through their own experiences of the disorder or through knowing people with depression. The participants also drew from psychosocial explanations of depression and located depression as part of the human condition. The paper suggests that lay people's concepts of depression offer rich complex and diverse perspectives that enhance professional views and may lead to a greater understanding of uptake and acceptance of care for depression.

Abstract
Toneburst-evoked auditory brainstem responses (ABRs) were recorded in a captive subadult male leopard seal. Three frequencies from 1 to 4 kHz were tested at sound levels from 68 to 122 dB peak equivalent sound pressure level (peSPL). Results illustrate brainstem activity within the 1-4 kHz range, with better hearing sensitivity at 4 kHz. As is seen in human ABR, only wave V is reliably identified at the lower stimulus intensities. Wave V is present down to levels of 82 dB peSPL in the right ear and 92 dB peSPL in the left ear at 4 kHz. Further investigations testing a wider frequency range on seals of various sex and age classes are required to conclusively report on the hearing range and sensitivity in this species.

Abstract
Dysfunctional swallowing is an uncommon, but important cause of bronchiectasis. We describe a child with a brainstem tumor, who developed bronchiectasis caused by chronic aspiration secondary to a dysfunctional swallow. The case highlights the importance of thorough and repeated evaluation before a diagnosis of idiopathic bronchiectasis is made. If dysfunctional swallow is found further investigation to ascertain the cause is indicated.

Abstract
AIM To investigate the clinical range and severity of radiological findings in a cohort of patients with primary ciliary dyskinesia (PCD) receiving tertiary care. MATERIALS AND METHODS The case notes and clinical test results of 89 children attending the paediatric respiratory disease clinic at our institution were retrospectively analysed. Demographic details including age at diagnosis and common presenting signs and symptoms were studied. Results of chest radiographs, microscopy, and high-resolution computed tomography (HRCT) for quantification of lung damage were analysed. RESULTS In a cohort of 89 children with PCD, a presentation chest radiograph was available in 62% of patients (n=55), with all but one demonstrating changes of bronchial wall thickening. HRCT of the lungs, available in 26 patients, were scored using the system described by Brody et al. analysing five specific features of lung disease, including bronchiectasis, mucus plugging, peribronchial thickening, parenchymal changes of consolidation, and ground-glass density, and focal air-trapping in each lobe. Peribronchial thickening was observed using HRCT in 25 patients, while 20 patients had bronchiectasis. Severity scores were highest for the middle and the lingular lobes. CONCLUSION The radiographic findings of the largest reported cohort of patients with PCD are presented, with associated clinical findings. Dextrocardia remains the commonest finding on chest radiography. HRCT demonstrates peribronchial thickening and bronchiectasis, which is most marked in the lower zones. Radiological scoring techniques developed for assessment of cystic fibrosis can also be applied for the assessment of disease severity in this patient population.

Abstract
Increasingly, lay people are appointed as members to health service committees. The term 'lay' is used loosely and the reasons for involving lay people are seldom clearly defined. This paper argues that the different roles that lay people play need to be explicitly defined in order for their contributions to be realized. Although lay members of health service committees are generally assumed to be working for patients' interests, our observations lead us to think that some lay people tend to support professionals' or managers' interests rather than patients' interests as patients would define them. We suggest that lay people fall into three broad categories: supporters of dominant (professional) interests, supporters of challenging (managerial) interests and supporters of repressed (patient) interests. These alignments should be taken into account in appointments to health service bodies. Further research is needed on the alignments and roles of lay members.

Abstract
BACKGROUND It is difficult to quantify thresholds in most colour vision tests, and this is especially the case for tritan hues, where a strong age-related increase of threshold has been reported. With the development of computer-graphic methods it is possible to remove brightness clues caused by lens absorption. This study attempts to give normative values for colour contrast thresholds and assess the age related changes therein. PATIENTS AND METHODS 115 patients aged between 6 & 71 years were tested for central and peripheral colour contrast sensitivity. No patient had any systemic or eye disease. As a preliminary, heterochromatic flicker balance between the luminosities of the R and G and B and G phosphors was established, so that all colours subsequently generated were isoluminant for the person tested. Then, using a modified binary search technique, colour contrast thresholds were established using both 2 degree optotypes, for central vision, and a ring, 12.5 degrees in radius for peripheral vision. In the latter case, the observer had to name the position of the missing quadrant in the ring. Stimuli were presented for 200 msec at 1 Hz. Colours were modulated on protan, deutan or tritan colour axis. RESULTS No correlation between age and central colour vision thresholds was observed. By contrast a significant but only minor increase of peripheral colour vision threshold was observed for the peripheral protan and tritan axis. DISCUSSION The present system removes luminance clues from colour vision tests and permits both central and peripheral retina to be tested. The results are simple in that the influence of age can be neglected. The variability of threshold results is small, and it is easy to detect the relatively large changes associated with disease. Since high-quality monitors are standardised and calibrated, providing the stimulus parameters described are adhered to, the results given here for upper limits of normal may be used for other similar systems.

Abstract
Monocyte chemoattractant protein (MCP-1) is a specific chemoattractant for monocytes/macrophages that could have a role in the influx of macrophages into the corpus luteum (CL) during structural luteolysis. In this study, reverse transcription-polymerase chain reaction and in situ hybridization were used to investigate MCP-1 mRNA expression in CL collected from 18 heifers between Days 15 and 20 of the estrous cycle. There was expression of mRNA encoding MCP-1 in luteal tissue from all cows; however, expression was greater in animals that had undergone luteolysis at the time of CL collection as compared to animals in which the CL was still functional. Similarly, in situ hybridization showed greater expression of mRNA encoding MCP-1 in CL after functional luteolysis. There was also evidence of increased MCP-1 mRNA expression in an animal with a functional CL where the systemic concentration of prostaglandin F2alpha metabolite was high at the time of tissue collection. T lymphocyte populations, identified by immunohistochemistry, had a distribution similar to that of cells expressing MCP-1 mRNA within the CL, but other cell types were also involved. These results demonstrate an increase in MCP-1 mRNA after functional luteolysis in the cow, which may be related to the influx of macrophages that occurs at this time.

Abstract
Nurse prescribing was initiated in the United Kingdom in October 1994 in eight demonstration sites. The evaluation of this extension to the community nurses' role explored both economic and qualitative benefits to patients, carers, nurses and other health care professionals. In this paper the impact of nurse prescribing on patients is explored. Benefits experienced by patients are described along with the difficulties encountered. The patients' views regarding nurses as prescribers are also explored. Data were collected by means of interviews with patients/carers, the focus of which was to evaluate changes associated with nurse prescribing. Patients raised a number of issues associated with their relationship with nurses. Patients valued nurses for both their accessibility and approachability, which led them to discuss health issues which would not otherwise have been brought to the attention of the general practitioner. The arguments which support the incorporation of these qualities into an expanded nursing role are presented.

Abstract
From October 1994 qualified district nurses and health visitors from eight demonstration sites in England have been able to prescribe from a limited list of formulary items. Data collected from nurses formed only one part of the evaluation of nurse prescribing. These data highlighted a number of areas where prescribing nurses were faced with difficult decisions. A number of authors have considered how both doctors and nurses make decisions, and the factors which may influence the decision making process. With reference to the literature this paper focuses on the findings related to decision making in the context of nurse prescribing.

Abstract
In 1994 the law was changed to allow nurses to prescribe from a limited formulary. The Department of Health commissioned research to evaluate nurse prescribing in eight pilot sites in England. This article presents part of this research. In particular, it examines how patients perceived the role of nurses and health visitors as prescribers. The study involved interviewing patients seen by community nurses before and after the introduction of nurse prescribing. The advantages patients identified coincided with the anticipated benefits, while the disadvantages that had been anticipated before the study were not confirmed. Patients were positive about nurses as prescribers and in some instances preferred nurses to doctors.

Abstract
Population based studies have demonstrated that having a first degree relative with a hip fracture is predictive of future hip fractures. Postmenopausal bone mineral density (BMD), ultrasound of calcaneus and hip axis length are associated with hip fracture, with the association for ultrasound and hip axis length being independent of BMD. The aim of this study was to determine the genetic component of these three important risk factors. We performed a classical twin study using 500 normal female twins, 128 identical and 122 non-identical pairs, aged 50 to 70 years. We measured bone mineral density at multiple sites, hip axis length (distance from the inner rim of the acetabulum to the greater trochanter), broadband ultrasound attenuation and velocity of sound of the calcaneus. Bone density had a strong genetic component at all sites with estimates of heritability ranging from 0.46 to 0.84. Hip axis length and velocity of sound had major genetic components with estimates of 0.62 and 0.61 respectively, which remained virtually unchanged after adjustment for bone mineral density. Broadband ultrasound attenuation had a moderate genetic component with an estimate of 0.53, which was reduced further to 0.45 after adjustment for BMD. In summary, all three bone measurements, which are independently associated with hip fracture, are independently heritable. This study suggests that a combination of different genetic factors acting on the structure, dimensions and density of bone may explain the importance of family history as a risk factor for hip fracture.

Abstract
We report a family in which autosomal dominant congenital nystagmus cosegregates with a balanced 7;15 translocation. Ophthalmic investigation showed predominantly horizontal nystagmus with a small rotatory component and no significant loss of visual function. This finding suggests a possible localisation for autosomal dominant congenital nystagmus (McKusick 164100).

Abstract
PURPOSE To investigate two apparent anomalies of the human electroretinogram: the "on" and "off" components of the cone based PIII are unequally sized, and transitions from red to green, which are electroretinographically silent, yield reverse transitions (green to red) in which a-waves develop. METHODS Ganzfeld electroretinograms were obtained with intense 100 msec flickering flashes from red and green light-emitting diode. Such stimuli light-adapt the retina, and the responses are caused by the excitation of long and medium wavelength cones. RESULTS In the 10-20 msec after the beginning of a flash (black to green or black to red) the beginning of rapid receptor-generated a-wave is seen. Ten to twenty milliseconds after the end of the flash, the beginning of a rapid positive-going off response, also derived from receptors can be seen. If the retina is stimulated by the abrupt change from one wavelength of light to another (eg, from "green" to "red"), at times > 20 msec after the change there are always slow changes in potential (presumably caused by postsynaptic activity) regardless of the relative intensities of red and green. However, if the two light intensities are adjusted appropriately, 10-20 msec after the transition from green to red no electroretinographic a-wave (or off response) develops--the transition is "silent." When the transition reverses (changes back from red to green), an a-wave occurs. In the same way if a red-to-green transition is made silent by altering the relative light intensities, the green-to-red reversal evokes an a-wave. This occurs for numerous pairs of red and green intensities. Rod intrusion or minor electroretinogram components do not explain this result. The relative red:green intensity in two color-anomalous subjects is different to that in three normal subjects. The rule for a silent transition is that the decrease in excitation in one cone type should be twice the increase in excitation in the second cone type. CONCLUSIONS The most likely cause is a reduction in the amplitude of cone receptor potentials 20-50 msec after the onset of the stimulus, caused by a sign-reversing feedback mechanism such as that described in amphibians. This implies that the chromatic signals for color vision required by theorists are partly generated in the cones.

Abstract
Thirty one eyes with established glaucoma, 61 high risk ocular hypertensive (OHTs) eyes, 66 medium risk OHT eyes, 58 low risk OHT eyes, and 47 control eyes have been followed for up to 2 years by clinical examination and pattern electroretinography (PERG). The study was 'masked' so electrophysiological and clinical data were kept separate. Criteria have been devised which enable PERG measurements to distinguish all established glaucomatous eyes from all normal controls; these criteria demonstrate abnormalities in some OHT eyes, particularly those at high risk. The PERG abnormality is greatest in eyes with established glaucoma in which the intraocular pressure has been lowered by treatment. The PERG becomes smaller as the degree of clinical abnormality increases. Test-retest variability of the PERG is sufficiently low to ensure that most of those first described as abnormal continue to be so.

Abstract
Colour contrast sensitivity (CCS) of a large cohort of glaucomatous patients, ocular hypertensive patients (OH), and normal persons was measured at six-month intervals during a two-year period. The OHs were graded into high, medium, and low risk groups. 69% of glaucomatous patients and 32% of all OHs had CCS thresholds greater than the mean plus 2 SDs of the controls. Satisfactory specificity and sensitivity could not be obtained by adjusting the criterion of threshold. In abnormal eyes, progressive small increases of threshold occurred during the study, but glaucomatous eyes with normal thresholds on the first visit retained normal thresholds in the subsequent visits. Although our system is very sensitive and precise, the proportion of abnormalities detected is no greater than with other techniques. In some glaucomatous patients there is a true preservation of colour vision which does not merely reflect the limitations of the test employed.

Abstract
Christine Hogg and Fedelma Winkler review the major and varied changes being introduced in the management of community health councils by different regional health authorities in the wake of the NHS Bill. This piecemeal approach may lead to more variations in the standards of service that individual CHCs offer the public and they argue that there needs to be a coherent policy about the role of CHCs and evaluation and monitoring of their functions.

Abstract
Eighty-five adults with horizontal concomitant strabismus were treated with an injection of a low dose of botulinum toxin A (BTXA) into the lateral or medial rectus muscle. The ocular deviation was reduced by an average of 60% independently of its size and whether or not surgery had previously been performed. The change was temporary, however, except in those cases with binocular functions, when fusion was re-established. Repeated low dose injections can maintain the improvement, but at higher doses, although larger reductions are produced, temporary local side effects--ptosis and vertical strabismus--are common. The technique is simple, well tolerated, and has no systemic side effects.
