Significantresearch efforts are currently directed towards the synthesis and studies of durable anion exchange membranes (AEMs) with the aim to develop alkaline fuel cells and electrolyzers able to operate efficiently without platinum-groupmetal catalysts [1]. The grand challenge is to identify and synthesize polymeric AEM materials possessingthe necessary chemical and thermal stability. Studies o

Objective: To find out what factors influence the outcome of operations for ischaemic bowel disease. Design: Retrospective study. Setting: University hospital, Sweden. Main outcome measures: Morbidity and mortality. Subjects: 74 patients, mean age 75 years (range 40-98), operated on for acute bowel ischaemia between 1987 and 1996. Results: A total of 75 emergency operations were done, including 42

Objective: To validate a 7-day estimated dietary record routine with standardized portion sizes and household measuring in a clinical setting with the doubly labelled water (DLW) method as the reference method. Design: Energy expenditure was measured with deuterium (2H) and oxygen-18 (18O), and water loss was estimated by 2H dilution as part of the DLW measurements. Energy and water intake was mea

Two patients (one with glaucoma with field loss, one with ocular hypertension) with previously known optic disc haemorrhage were followed with frequent disc photography, computerized perimetry and tonometry for a period of one year. Nine haemorrhages were seen in three of the four eyes studied. Three bleedings showed sudden enlargements, interpreted as re-bleedings, during the absorption phase. Ha

The present article discusses the role of computerized perimetry in the management of patients with suspect and manifest glaucoma. The value of visual field examination is compared to that of inspection and photography of the optic disc and to some extent to retinal nerve fibre layer photography. Computerized perimetry is related to standard manual visual field examination. Guidelines are offered

Sixty-three normal subjects and 94 abnormal patients, most of whom had glaucoma, were tested in the central visual field using a threshold-related, eccentricity-compensated, spatially adaptive suprathreshold screening program and a full-threshold program on the Humphrey field analyzer. The initial stimulus locations on the screening test were identical to those of the threshold test; additional sc

During the last few years computerised perimetry has become a clinical reality. This new technique eliminates the operator's error, ensures reproducibility of test procedures and parameters and makes visual field testing of large numbers of patients possible. Great differences exist between computerised perimeters. Differences in hardware for example, the way in which stimuli or field charts are p

With laser iridotomy it may often be difficult to achieve total penetration of the iris, particularly in very light or very dark irides. It may be impossible to determine with the slit-lamp whether a small laser iridotomy is functionally penetrating. We describe a straightforward method to test iridotomies for aqueous flow patency. Transcorneally introduced fluorescein is used to delineate any aqu

Seventy-seven eyes with primary open angle glaucoma and exfoliation glaucoma were subjected to laser trabeculoplasty and followed in a prospective way. The full 360 degrees circumference was treated, but the patients were randomized in two groups: In group 1 the full treatment was given in one session, and in group 2 it was divided into two sessions one month apart. During the follow-up time of 3

Computerized visual field testing with the Competer automatic perimeter including automatic profile perimetry revealed early glaucomatous field loss in 9 of 10 eyes with photographically demonstrable retinal nerve fibre layer (RNFL) defects after optic disc haemorrhages despite the fact than conventional routine perimetry had failed to do so. In 7 of these cases the Competer central pattern test w

2500-3000 eyes with ocular hypertension, with or without established glaucoma in the fellow eye, were followed with automatic perimetry for several years. Forty-five eyes showed a documented change from repeated normal fields to reproducible glaucomatous visual field loss. The location of the defective points in the first pathological field of each eye was registered. The resulting frequency distr
