Abstract
The identification and SAR development of a series of negative allosteric modulators of the GABAA α5 receptor is described. This novel series of compounds was optimised to provide analogues with high GABAA α5 binding affinity, high α5 negative allosteric modulatory activity, good functional subtype selectivity and low microsomal turnover, culminating in identification of ONO-8590580.

Abstract
Dobutamine stress echocardiography has become widely accepted as a safe, reliable and cost effective modality for the evaluation of patients with suspected myocardial ischemia or for prognostic stratification and outcome assessment in patients with known coronary artery disease. while the benefits of this means of cardiovascular testing are very clearly apparent, it is important to understand and recognize possible complications. This paper discusses the occurrence of sustained, nonischemic ventricular tachycardia during dobutamine stress echocardiography in the absence of functional, physiologic or anatomic evidence of coronary artery disease or cardiomyopathy.

Abstract
Tryptase, a neutral protease, is selectively concentrated in the secretory granules of human mast cells, and its release into the circulation serves as a clinical marker of mast cell activation. The current study describes a new, more sensitive ELISA utilizing a newly developed, mouse monoclonal IgG1 antibody for capture called B12 and capable of detecting tryptase in normal plasma and serum. The greater sensitivity of the new immunoassay results in part from a greater portion of tryptase being detected. Mean levels of tryptase in serum from normal subjects from Richmond, Virginia (4.9 ng/ml; n = 56), Munich, Germany (3.8 ng/ml; n = 19), and Amersfoort, The Netherlands (1.9 ng/ml; n = 8) were as indicated. In 62 subjects with ongoing allergic rhinitis, tryptase levels were no different in serum than for 19 normal controls, indicating that local mast cell activation is not necessarily reflected in the circulation. In 61 subjects sensitive to honey bee or yellow jacket venom by history, the 17 destined to have a severe, hypotensive response to a sting challenge had higher levels of tryptase at baseline than mild reactors, nonreactors, and controls, suggesting that baseline levels of tryptase may predict the severity of the clinical response to allergen in sensitive subjects.

Abstract
This paper describes the way in which prism and cylinder lenses may be used to disguise orbital dystopia when the affected eye is blind. The lenses used can correct the height of the eye, the opening of the eyelids or the rotation or slant of the eye. Four cases are presented to illustrated this technique, which may be used either instead of, or as an adjunct to orbital surgery. An investigation of these effects is described using a mannikin head fitted with an optician's trial frame, with measuring by the reflex metrograph. This revealed that an inferiorly displaced eye may be elevated by 4 to 5 mm, that the vertical eyelid opening may be widened (or narrowed) by just under 20% and that an adverse slant of the eye may be rotated in either direction by about 4 degrees.

Abstract
To assess attitudes toward chronically and acutely mentally and physically ill individuals, 106 undergraduates read one of four vignettes describing a hospitalized individual, with each vignette divided along the factors of diagnosis (schizophrenia or cancer) and chronicity (acute or chronic). Then they completed the Community Acceptance Scale and responded to 19 rationally derived paired adjectives. A series of 2 × 2 univariate analyses indicated that individuals with diagnoses of schizophrenia were viewed significantly more pejoratively than individuals with diagnoses of cancer. Similarly, individuals with chronic courses of treatment were viewed significantly more negatively than individuals with acute courses of treatment. Surprisingly, however, no univariate interactions reached statistical significance. Findings suggest that the lack of acceptance of the chronically mentally ill individual is a function of the devaluation associated with psychiatric diagnosis.
