O'Harte FPM, Parthsarathy V, Hogg C, Flatt PR. Apelin-13 analogues show potent in vitro and in vivo insulinotropic and glucose lowering actions. Peptides 2018; 100:219-228. [PMID: 29412822 DOI: 10.1016/j.peptides.2017.12.004] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2017] [Revised: 12/01/2017] [Accepted: 12/04/2017] [Indexed: 01/08/2023]
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.
