The neonatal Fc receptor (FcRn) transports maternal immunoglobulin (IgG) across epithelia to confer passive immunity to mammalian young. In newborn rodents, FcRn transcytoses IgG from ingested milk across the intestinal epithelium for release into the bloodstream. We used electron tomography to examine FcRn transport of Nanogold-labeled Fc (Au-Fc) in neonatal rat jejunum, focusing on later aspe...

The Frankl’s conjecture, formulated in 1979. and still open, states that in every family of sets closed for unions there is an element contained in at least half of the sets. FC-families are families for which it is proved that every union-closed family containing them satisfies the Frankl’s condition (e.g., in every union-closed family that contains a oneelement set a, the element a is contain...

BACKGROUND The present study examined putative modulators and indices of brain serotonergic and dopaminergic function, perceptual responses, and endurance exercise performance following caffeine co-ingested with a high fat meal. METHODS Trained humans (n = 10) performed three constant-load cycling tests at 73% of maximal oxygen uptake (VO2max) until exhaustion at 10 degrees C remove space thr...

We examine the topological characteristic cohomology classes of complexified vector bundles. In particular, all the classes coming from real vector bundles are computed. We use characteristic classes with the axioms of Milnor and Stasheff [6]. Introduction Definition (Real generator bundles). We consider a real vector bundle F → B and a complex vector bundle E → B over the same base space B. If...

Let μ be a Ruelle measure on the configuration space ΓRd with a pair potential φ. Then the generator of the corresponding intrinsic Dirichlet form (Eμ, H 0 (ΓRd ;μ)) is an extension of the Dirichlet operator ∆φ on L (ΓRd ;μ) with domain FC∞ b defined by ∆φ = div Γ φ∇. Here FC∞ b is the set of smooth cylinder functions, ∇Γ the gradient of the Riemannian structure on ΓRd and div Γ φ the correspon...
