Preparation and characterization of basolateral plasma-membrane vesicles from sheep parotid glands. Mechanisms of phosphate and D-glucose transport.

A procedure is described for the preparation of basolateral membrane vesicles from the acinar cells of the sheep parotid gland. The ouabain-sensitive K(+)-activated phosphatase activity was enriched 30-fold over the tissue homogenate; 45% of this activity was recovered in the final membrane fraction. The presence of membranes from other organelles was negligible. Evidence is presented for the location of Na(+)-dependent symporters for phosphate and D-glucose on the basolateral membrane.

Sensitivity to the displacement of facial features in negative and inverted images.

Subjects have previously been reported to show difficulties in recognising faces which are either inverted or in photographic negative. Experiments are reported in which a two-alternative forced-choice technique was used to measure sensitivity for distinguishing faces which have been modified by having the eyes moved vertically or horizontally. Subjects were less sensitive to such changes for inverted faces or negative faces, and were even less sensitive for faces that were both inverted and negative. No such effects were found for a control stimulus consisting simply of three solid circles in the same positions as the eyes and mouth of a face. When the stimuli consisted of eyes, nose, and mouth, but without a surround, no evidence of inversion or negation effects was found, which suggests that a facial surround is necessary. When the stimulus consisted of a facial surround with the eyes, nose, and mouth replaced by solid circles, effects of negation were found, but no effects of inversion. This dissociation of the effects of negation and inversion may suggest that they are the result of different underlying mechanisms.

Brucellosis complicated by aortic valve endocarditis.

A 30 year old veterinary surgeon developed a febrile illness with serological evidence of Brucellosis. He was known to have aortic valve disease and during the course of the illness, the clinical features of endocarditis became evident, with a vegetation visible echocardiographically on the aortic valve. Because of persisting fever despite appropriate antibiotic therapy, aortic valve replacement with a viable cryopreserved allograft aortic valve was undertaken. Organisms consistent with Brucella species were demonstrated in the excised vegetation. The patient received a six week course of antibiotics and his post-operative course was uneventful.

On weighing gains and investments at the margin of risk regulation.

Analysts have long noted an apparent discrepancy in the level of investment seemingly necessary to meet "acceptable" levels of public safety. At the margin of risk regulation, i.e., where safety determination is judged acceptable, the traditional cost-benefit calculus appears to contribute obvious rationale to the final political decision. Efforts are now being made to introduce a measure of consistency into the application of risk-cost benefit analysis to radiological protection. This paper reviews these efforts from a UK perspective. It also looks at how the issue was treated in a public setting through the Sizewell B Public Inquiry.
