In this paper, we derive a polyphase analysis to determine the optimum filters in a subband adaptive filter (SAF) system. The structure of this optimum solution deviates from the standard SAF approach and presents its best possible solution only as an approximation. Besides this new insight into SAF error sources, the discussed analysis allows to calculate the optimum subband responses and the ...

In an earlier work done in our laboratory, we have been able to isolate a sperm agglutinating strain of Escherichia coli from the semen sample of a male attending infertility clinic. Further, factor responsible for sperm agglutination (SAF) was isolated and purified, and, using SAF as a tool, corresponding SAF binding receptor from human spermatozoa has been purified. Characterization of SAF an...

We were interested by the article from De Corte et al. about the poor long-term outcome after acute kidney injury (AKI) [1]. Besides initial oliguria, the three predictors for dialysis dependence were age, diabetes, and chronic kidney disease (CKD), which have previously been related to the accumulation of advanced glycation end-products (AGEs) as evaluated by skin autofluorescence (sAF). sAF i...

Because it is often difficult to diagnose invasive Candida infections, a sensitive hemagglutination inhibition assay to detect the surface antigen, mannan, was developed. Mannan antigenemia was detected early in the course of infection in 4 of 14 patients with systemic candidiasis and 2 of 5 patients with invasive gastrointestinal candidiasis. Mannan was not detected in 48 patients with noninva...

A procedure is given for the insolubilization of yeast mannan by entrapment in a polyacrylamide gel. Specific anti-mannan antibodies were separated by immunosorption from all other antibodies of a rabbit antiserum against whole, Formalininactivated Candida utilis cells. Colloidal gold coated with the anti-mannan and anti-non-mannan antibody fractions was used for the ultrastructural visualizati...

BACKGROUND Most preclinical studies are carried out on mice. For internal dose assessment of a mouse, specific absorbed fraction (SAF) values play an important role. In most studies, SAF values are estimated using older standard human organ compositions and values for limited source target pairs. OBJECTIVE SAF values for monoenergetic photons of energies 15, 50, 100, 500, 1000 and 4000 keV we...

OBJECTIVES The aim of the present study was to investigate immunotoxic effect of safranal (SAF), a main component of Crocus sativus essential oil, using Balb/c mice. MATERIALS AND METHODS SAF was administered intraperitoneally at doses of 0.1, 0.5 and 1 ml/kg for 3 weeks. Hystopathological examination of spleen and bone marrow, cellularity of spleen, delayed type of hypersensitivity (DTH) res...

Segregation of chromosomes during cell division requires correct formation of mitotic spindles. Here, we show that a scaffold attachment factor A (SAF-A), also known as heterogeneous nuclear ribonucleoprotein-U, contributes to the attachment of spindle microtubules (MTs) to kinetochores and spindle organization. During mitosis, SAF-A was localized at the spindles, spindle midzone and cytoplasmi...

BACKGROUND The metabolic syndrome (MetS) comprises several cardiometabolic risk factors associated with increased risk for both type 2 diabetes and cardiovascular disease. Skin autofluorescence (SAF), a non-invasive biomarker of advanced glycation end products accumulation, is associated with cardiovascular complications in subjects with diabetes. The aim of the present study was to examine the...

BACKGROUND We aimed to analyze the relationships between skin autofluorescence (SAF) and incident macrovascular events and renal impairment after 4 years of follow-up in patients with type 1 diabetes (T1D). METHODS Two hundred and forty-three patients (51.2 ± 16.7 years old) with T1D participated. SAF was measured by AGE-Reader-TM at inclusion. Macrovascular events (MVE), estimated glomerular...
