Using a function algebra characterization of exponential time due to Monien 5], in the style of Bellantoni-Cook 2], we characterize exponential time functions of linear growth via a safe course-of-values recursion scheme.

It is essential to understand the consumption pattern of food and how it changes over time to formulate sound economic policies as well as marketing and pricing strategies. In this study, we estimate the Quadratic Almost Ideal Demand System with six rounds of the Family Income Expenditure Survey exploiting the conditional linearity of the demand system. We find that the Filipino diet has become...

Small extracellular vesicles (sEVs) such as exosomes are nanocarriers of proteins, RNAs and DNAs. Isolation of pure sEV populations remains challenging, with reports of protein and lipoprotein contaminants in the isolates. Cellular uptake - a cornerstone for understanding exosome and sEV function - is frequently examined using lipophilic dyes such as PKH67 or CellMask to label the vesicles. In ...

Recently, we reported the isolation and identification of a potent vasoconstrictor enzyme from the rat submandibular gland, a member of the rat kallikrein gene family, which we named submandibular enzymatic vasoconstrictor (SEV). We studied whether messenger RNA (mRNA) for SEV is present in the kidney and isolated glomeruli, using the polymerase chain reaction assay with primers specific to the...

PURPOSE Sendai virus (SeV), a murine parainfluenza virus type I, replicates independent of cellular genome and directs high-level gene expressions when used as a viral vector. We constructed a nontransmissible recombinant SeV vector by deleting the matrix (M) and fusion (F) genes from its genome (SeV/DeltaMDeltaF) to enhance its safety. We also estimated the therapeutic efficacy of the novel ve...

The specification of the R7 photoreceptor cell in the developing eye of Drosophila is dependent upon activation of the Sevenless (SEV) receptor tyrosine kinase. By screening for mutations that suppress signaling via a constitutively activated SEV protein, we have identified a novel gene, daughter of sevenless (dos). DOS is required not only for signal transduction via SEV but also in other rece...

BACKGROUND The aim of this study was to evaluate the subjective elbow value (SEV) and compare it with the Mayo Elbow Performance Score (MEPS). The SEV is defined as the patient's subjective estimation of the elbow as a percentage of a normal elbow, which would correspond to 100%. METHODS The MEPS and the SEV were prospectively assessed in all patients treated for any elbow pathology. Two grou...

The pleckstrin homology (PH) domain-containing protein Daughter of Sevenless (DOS) is an essential component of the Sevenless receptor tyrosine kinase (SEV) signaling cascade, which specifies R7 photoreceptor development in the Drosophila eye. Previous results have suggested that DOS becomes tyrosine phosphorylated during SEV signaling and collaborates with the protein tyrosine phosphatase CSW....

Purpose The fixed flexion view (FFV) of the knee is considered useful for evaluating the joint space when assessing the severity of osteoarthritis (OA) of the knee. To clarify the usefulness of FFV for evaluation of the joint space and severity of knee OA, this study evaluated changes in the joint space on the FFV and standing extended view (SEV) in patients with knee OA. Materials and Method...
