13. Geração e vetorização de instruções de multiplicação e acumulação para processadores DSP SIMD
Application specific processors - as opposed to general purpose processors - account for an ever increasing percentage of the processors sold each year. These processors are widely used in electronic devices such as cellular phones and digital cameras, medical monitoring devices, modems, military radar systems, electronic components in vehicles and set-top b

14. Suco de laranja concentrado : comportamento reologico a baixas temperaturas
This work determined the Mow behaviour of orange juice (pear orange), with 10 per cent of suspended pulp, in the concentrations of 55,0, 60,0 and 64,2 °Brix. The temperature range for the concentrations of 64,2 and 55,0 °Brix was from 20,5 to -19,4 (>C and for concentrations of 60,0 °Brix from +20,0 to -23,0 °C. Experimental data were fitted by Casson, H

15. Clinical significance of upper airway dysfunction in motor neurone disease.
BACKGROUND--To assess the occurrence, functional characteristics and prognostic value of upper airway dysfunction in motor neurone disease, 27 patients unselected for respiratory symptoms were studied. METHODS--Upper airway function was evaluated by analysis of the maximal flow-volume loop. Neurological diagnosis was established from the clinical history and

16. Loop of Henle bicarbonate accumulation in vivo in the rat.
We have carried out perfusion studies on hydropenic and bicarbonate-loaded rats to provide direct in vivo observations on bicarbonate accumulation in the short loops of Henle. Analysis of early distal tubular fluid was made during bicarbonate-free saline perfusion from the end proximal to the early distal site, documenting accumulation of "new" bicarbonate.

17. The flow-volume loop: reproducibility of air and helium-based tests in normal subjects
A statistical technique new to lung function testing is described and has been applied to a study of flow-volume loop tests in normal subjects. Maximal expiratory flow-volume loops were performed on air, then breathing an 80% helium: 20% oxygen mixture for three deep breaths (3B) then three minutes (3M) twice daily for five consecutive days on 25 asymptomati

18. Comparison of normal and asthmatic circadian rhythms in peak expiratory flow rate.
A computer technique (cosinor analysis) has been used to evaluate circadian rhythms in airway calibre in normals and asthmatics. Two hundred and twenty-one normal subjects recorded peak expiratory flow rate (PEFR) at home four times a day for seven days. Rhythm detection was statistically significant in 145 of them (65.6%) who showed a mean amplitude of 8.3%

19. Segmental analysis of renal glucose transport in young female rats.
Free-flow micropuncture studies were performed on twenty-seven young female Sprague-Dawley rats before and after 10% extracellular volume expansion to evaluate glucose reabsorption at the accessible sites of both surface and papillary nephrons. In the distal nephron segments no significant glucose reabsorption was observed for the distal tubule and papillary

20. Isolation of molecular probes associated with the chromosome 15 instability in the Prader-Willi syndrome.
Flow cytometry and recombinant DNA techniques have been used to obtain reagents for a molecular analysis of the Prader-Willi syndrome (PWS). HindIII total-digest libraries were prepared in lambda phage Charon 21A from flow-sorted inverted duplicated no. 15 human chromosomes and propagated on recombination-proficient (LE392) and recBC-, sbcB- (DB1257) bacteri

21. Consequences of potassium recycling in the renal medulla. Effects of ion transport by the medullary thick ascending limb of Henle's loop.
The consequences of K recycling and accumulation in the renal medulla were examined by measuring the effect of elevated K concentration on ion transport by the medullary thick ascending limb of Henle's loop. Perfused and bathed in vitro, thick limbs from both mouse and rabbit displayed a graded, reversible reduction of transepithelial voltage after increasin

22. Specific In Vivo Labeling of Cell Surface-Exposed Protein Loops: Reactive Cysteines in the Predicted Gating Loop Mark a Ferrichrome Binding Site and a Ligand-Induced Conformational Change of the Escherichia coli FhuA Protein
The FhuA protein of Escherichia coli K-12 transports ferrichrome, the antibiotic albomycin, colicin M, and microcin 25 across the outer membrane and serves as a receptor for the phages T1, T5, φ80, and UC-1. FhuA is activated by the electrochemical potential of the cytoplasmic membrane, which probably opens a channel in FhuA. It is thought that the proteins

23. Modulation of renal medullary ionic hypertonicity by prostaglandins: data from tissue admittance studies in the rat.
1. Modulation of the cortico-papillary electrolyte gradient by prostaglandins (PG) was studied in the kidney of anaesthetized rats. The intrarenal PG activity was varied by synthesis blockade with indomethacin (Ind) or meclophenamate (Me) and by intrarenal infusion of prostaglandin E2 (PGE2). 2. The interstitial electrolyte concentration in the medulla was c

24. Localization of binding sites of staphylococcal enterotoxin B (SEB), a superantigen, for HLA-DR by inhibition with synthetic peptides of SEB.
Staphylococcal enterotoxins are major causes of food poisoning and toxic shock syndrome. Their ability to bind to major histocompatibility complex (MHC) class II molecules has been suggested to be the first step in the mechanism whereby they cause illness. By flow cytometric analysis, the sites of interaction of staphylococcal enterotoxin B (SEB) with HLA-DR
