| the role of alternating air and silicore overlays in preventing decubitus ulcers. | patients with chronic neurological diseases who were at high risk of decubitus ulcers were randomly assigned to alternating air on silicore mattress overlays for a period of 3 months. of 148 subjects who completed the trial, more than 50% in each group developed one or more ulcers. no statistically significant differences between groups were found in the incidence, severity, healing duration or the location of the ulcers; with the exception of a significant difference (p less than 0.001) in the ... | 2007 | 2394540 |
| lauryl sulphate haemoglobin: a non-hazardous substitute for hicn in haemoglobinometry. | the haemiglobincyanide (hicn) method for measuring haemoglobin is used extensively worldwide; its advantage is the ready availability of a stable and internationally accepted reference standard/calibrator. however, its use may create a problem, especially in automated analysers, as the waste disposal of large volumes of reagent containing cyanide may constitute a potential toxic hazard. as an alternative, conversion of haemoglobin to a sulphate derivative by nontoxic sodium lauryl sulphate has b ... | 2007 | 1794230 |
| [induction of autoreactive t-cells by bacterial stress proteins in hla-dr4 donors]. | from the peripheral blood of hla-dr4+ healthy donors or patients with rheumatoid arthritis autoreactive t-cell lines were obtained after stimulation with bacterial heat-shock protein. all lines obtained express an alpha/beta-t-cell receptor and they are predominantly cd4+. the determination of the fine specificity of those autoreactive t cells showed, that either amino-acid position #71 or #86 of the hla-dr beta 1 chain was critical for recognition by the antigen receptor. | 2007 | 1855814 |
| inbreeding in saguenay-lac-st-jean (quebec, canada): a study of catholic church dispensations 1842-1971. | saguenay-lac-st-jean (slsj) is a rather geographically isolated region of quebec which shows a high occurrence of hereditary disorders. it has been suggested that high inbreeding might explain this situation. we studied the inbreeding in the slsj region by 10-year periods from 1842 till 1971 using the catholic church dispensations. the values of the mean inbreeding coefficient were found to be low during the whole period, reaching a peak of 22.94 x 10(-4) during the period 1902-1911. the values ... | 2007 | 1797631 |
