We present a measurement of the K-band luminosity function (LF) of field galaxies obtained from near-infrared imaging of a sample of 345 galaxies selected from the Stromlo-APM Redshift Survey. The LF is reasonably well fitted over the 10-mag range 226 < MK < 216 by a Schechter function with parameters a ˆ 21:16 ^ 0:19; M* ˆ 223:58 ^ 0:42 and f* ˆ 0:012 ^ 0:008 Mpc, assuming a Hubble constant of...

BACKGROUND The vulnerability-stress hypothesis is an established model of schizophrenia symptom formation. We sought to characterise the pattern of the cardiac autonomic response to mental arithmetic stress in patients with stable schizophrenia. METHODS We performed heart rate variability (HRV) analysis on recordings obtained before, during, and after a standard test of autonomic function inv...

α s2-casein f(183-207) and lactoferricin [lactoferrin f(17-41)] are two potent 3 antibacterial peptides derived from bovine milk proteins. The aim of this work was to 4 evaluate if the antimicrobial activity of natural compounds employed in food 5 preservation such as nisin could be enhanced by combination with the aforementioned 6 milk peptides. Combinations with lactoferrin were also performe...

Let α ∈ (0, 2) and consider the operator Lf(x) = ∫ [f(x+ h)− f(x)− 1(|h|≤1)∇f(x) · h] A(x, h) |h|d+α dh, where the ∇f(x) · h term is omitted if α < 1. We consider the martingale problem corresponding to the operator L and under mild conditions on the function A prove that there exists a unique solution.

The BrCN cleavage of lacteferrin-a or -b (LF-a or LF-b) led to the observation of four fragments by SDS-PAGE, whose molecular masses were 77, 58, 52, and 30kDas, or 74, 54, 47, and 30 kDas, respectiyely. N-TeTmina} amino acEd sequence analyses show that the sequences of 58, 52, and 30 kDa fragments (residues 6"71, 130-471, and 472-689) of LF-a coincide vvith those of the 54, 47, anG 30kDa fragm...

Given a C-function f on a compact riemannian manifold (X, g) we give a set of frequencies L = Lf (ε) depending on a small parameter ε > 0 such that the relative L-error ‖f−f ‖ ‖f‖ is bounded above by ε, where f L denotes the L-partial sum of the Fourier series f with respect to an orthonormal basis of L(X) constituted by eigenfunctions of the Laplacian operator ∆ associated to the metric g.

Lactoferrin (Lf) is an iron-binding multi-functional glycoprotein which has numerous physiological functions such as iron transportation, anti-microbial activity and immune response. In this study, different in silico approaches were exploited to investigate Lf protein properties in a number of mammalian species. Results showed that the iron-binding site, DNA and RNA-binding sites, signal pepti...
