The murine suppressive factor of allergy (SFA) has been purified from a T-cell hybridoma and found to consist of two functionally and biochemically distinct protein molecules. One protein (17 kDa) modulates the low-affinity Fc receptor for IgE on lymphocytes (i.e., CD23); it decreases the binding avidity of IgE to CD23-bearing B cells without affecting quantitative expression of CD23 and is thu...

ments suggest that at physiological concentrations, only urate contributes to the artifactually high pre-dialysis values. When a standard serum sample was increased in concentration (in vitro) from 11.6 to 54 mmol/L in urea, from 97 to 1130 mmol/L in creatinine, and from 0.31 to 1.38 mmol/L in urate, values for apparent SFA were unaffected by urea or creatinine changes, but rose 13% in the pres...

Slow Feature Analysis (SFA) extracts features representing the underlying causes of changes within a temporally coherent high-dimensional raw sensory input signal. Our novel incremental version of SFA (IncSFA) combines incremental Principal Components Analysis and Minor Components Analysis. Unlike standard batch-based SFA, IncSFA adapts along with non-stationary environments, is amenable to epi...

BACKGROUND The apolipoprotein E (APOE) gene promoter polymorphism (-219G-->T) has been associated with increased risk of myocardial infarction, premature coronary artery disease, and decreased plasma apolipoprotein E concentrations. OBJECTIVE We aimed to determine in healthy subjects whether this polymorphism modifies the susceptibility of LDL to oxidation and the lipid response to the conten...

Background: The apolipoprotein E (APOE) gene promoter polymorphism ( 219G3T) has been associated with increased risk of myocardial infarction, premature coronary artery disease, and decreased plasma apolipoprotein E concentrations. Objective: We aimed to determine in healthy subjects whether this polymorphism modifies the susceptibility of LDL to oxidation and the lipid response to the content ...

The lamellar phase of a lyotropic solution in a confined geometry is investigated with a surface force apparatus (SFA). The measured interaction between the two SFA surfaces immersed in the mesophase is periodic, oscillatory, decaying, and discontinuous. A model is developed to account for the specific confining geometry of the SFA It is based on an array of concentric dislocation loops that al...
