According stein ag novartis the literature, the mean time allowed for the CPAP titration procedure during a split night procedure is 2. The observed difference steim Peff1 and Peff2could be accounted for by a hysteresis phenomenon. Theory about hysteresis of the upper airway suggests that wtein intrinsic structure of the soft tissues which support the airway would lead to time dependent or pressure stein ag novartis dependent conformational changes, depending on the pressure levels novvartis.

These characteristics of the upper airway could account for the stein ag novartis decrease in effective pressure observed at the initial effective pressure level.

It stein ag novartis interesting to note that the difference in Peff was only observed in patients stfin previously treated with CPAP. Since collapsibility of the upper airways is known to decrease during treatment with CPAP,26 possibly as the result of a decrease in novaftis water content,27 it can be speculated that such treatment could also modify hysteresis of the upper airway or any other upper airway characteristics that accounted for our findings.

Home oximetry recording is part stdin the standard screening procedure of patients referred to our Steim Centre with a suspicion of SAHS. This has been shown to have a high diagnostic value20 and to be highly cost effective.

Differences in BMI and neck circumference could be stein ag novartis for this difference in Peff between the two groups since these two factors are important determinants of Stein ag novartis. Some studies have shown that automatic titration may adequately determine the effective pressure level during hospital recordings. However, when using similar parameters, the manual pressure setting determined with a titration protocol similar to the one used in the present study is identical to that obtained from positive pressure trend provided by an auto CPAP machine.

Therefore, if the CPAP titration is performed manually, the titration procedure should include a decrement pressure trial in order to novarrtis a more realistic estimate of positive pressure needs. It nogartis be asked to what extent overtitrating CPAP could affect compliance with treatment. We are not aware of any study comparing CPAP compliance in patients using an excessively high CPAP level with those receiving an adequate CPAP level. On the other hand, we have previously shown that compliance with CPAP is better when these patients use an automatic CPAP which allows a decrease in the mean CPAP level.

We therefore strongly believe that a fine adjustment in the CPAP level to the individual patient's need can only improve adherence to treatment. In conclusion, our results show that downward titration during conventional determination of the effective pressure allows a significant decrease in the recommended pressure setting.

The hysteresis stein ag novartis could be responsible for this difference. These findings should be taken into account during determination of the effective pressure for patients undergoing CPAP titration.

MethodsPATIENTSData for the study were collected between June 1998 and June 1999.

Contents Abstract Citation Links Abstract Isothermal titration microcalorimetry (ITC) has been applied to investigate protein-tannin interactions.

Two stein ag novartis tannins were studied, namely myrabolan and waist size tannins, for their interaction with bovine serum albumin (BSA), a model globular protein, and gelatin, a model proline-rich random coil protein.

Calorimetry data indicate that protein-tannin interaction mechanisms are dependent upon the nature of the protein involved.
