Let n > m 2:: 4 be positive integers. The edge framing number efr( Cm, Cn) of Cm and Cn is defined as the minimum size of a graph every edge of which belongs to an induced Cm and an induced Cn. We show that efr(Cm,Cn) = n+4 ifn = 2m-4 and m 2:: 5, efr(Cm,Cn) = n+5 if n = 2m-6 and m ~ 7 and efr(Cm1 Cn) = n+6 if n = 2m-8 (m ~ 10) or m = n -1 (where n ~ 5 and n ¢ {6,S}) or m = n 2 (n = 6 or n 2:: ...

Proper assembly of the class I heavy chain (HC), beta 2-microglobulin (beta 2m), and peptide must occur in the endoplasmic reticulum (ER) in order for MHC class I molecules to be expressed on the cell surface. Newly synthesized class I HC bind calnexin, an ER resident chaperone. These calnexin-associated class I HC appeared to lack the stable association with beta 2m in peptide transporter-defi...

Complex orthogonal designs (CODs) are used to construct space-time block codes. COD Oz with parameter [p, n, k] is a p × n matrix, where nonzero entries are filled by ±zi or ±z ∗ i , i = 1, 2, . . . , k, such that O H z Oz = (|z1| 2 + |z2| 2 + . . . + |zk| 2)In×n. Adams et al. in “The final case of the decoding delay problem for maximum rate complex orthogonal designs,” IEEE Trans. Inf. Theory,...

The proteinase "inhibitor" alpha 2-macroglobulin (alpha 2M) is able to entrap and form covalent linkages with diverse proteins during a transient proteinase-activated state. These complexes are rapidly endocytosed after binding to receptors present on macrophages and other cells. We have previously shown that compared to free hen egg lysozyme (HEL), alpha 2M-complexed HEL undergoes enhanced mac...

BACKGROUND Effects of prenatal iron supplementation on maternal postpartum iron status and early infant iron homeostasis remain largely unknown. OBJECTIVE We examined iron absorption and growth in exclusively breastfed infants in relation to fetal iron exposure and iron status during early infancy. DESIGN Longitudinal, paired iron-absorption (⁵⁸Fe) studies were conducted in 59 exclusively b...

OBJECTIVE The aim of the present study was to analyze alpha 2 Macroglobulin/MMP (alpha 2M/MMP) complex formation and to investigate whether MMP activity in alpha 2M/MMP complexes in serum can be used as a disease marker in rheumatoid arthritis (RA). METHODS High and low molecular weight (H/LMW) substrates and inhibitors and size exclusion were used to analyze alpha 2M/MMP complex formation. L...

We use methods of approximation theory to find the absolute minima on sphere potential spherical (2m−3)-designs with a non-trivial index 2m that are contained in union m parallel hyperplanes, m≥2, whose locations satisfy certain additional assumptions. The interaction between points is described by function dot product, which has positive derivatives orders 2m−2, 2m−1, and 2m. This includes cas...
