Only a few vaccines are commercially available against intestinal infections since the induction of a protective intestinal immune response is difficult to achieve. For instance, oral administration of most proteins results in oral tolerance instead of an antigen-specific immune response. We have shown before that as a result of oral immunization of piglets with F4 fimbriae purified from pathog...
Let k be an algebraically closed field of characteristic 2. Consider F4 ⊂ k and P(F4) ⊂ P(k). Let P be the set of points and let P̌ be the set of lines in P(F4). Each set contains 21 elements, each point is contained in exactly 5 lines, and each line contains exactly 5 points. It is known that the group of automorphisms of the configuration (P, P̌) is isomorphic to M21 ·D12, where M21(∼ = PSL(3,F...
Enterotoxigenic Escherichia coli (ETEC) are important intestinal pathogens that cause diarrhea in humans and animals. Although probiotic bacteria may protect against ETEC-induced enteric infections, the underlying mechanisms are unknown. In this study, porcine intestinal epithelial J2 cells (IPEC-J2) were pre-incubated with and without Lactobacillus rhamnosus ATCC 7469 and then exposed to F4+ E...
The semifields of order q6 which are two-dimensional over their left nucleus and six-dimensional over their center have been geometrically partitioned into six classes by using the associated linear sets in PG(3, q3). One of these classes has been partitioned further (again geometrically) into three subclasses. In this paper algebraic curves are used to construct two infinite families of odd or...
BACKGROUND AND RATIONAL Telaprevir-based therapy (TBT) has been extensively evaluated in clinical trials. So we designed a study to compare the efficacy and safety of TBT between patients with moderate fibrosis and those suffering from advanced fibrosis in clinical practice. A multicenter observational and ambispective study was conducted. It included 582 patients with chronic hepatitis C genot...
Oral immunization of both humans and animals with non-replicating soluble antigens often results in the induction of oral tolerance. However, receptor-dependent uptake of orally administered soluble antigens can lead to the induction of an antigen-specific immune response. Indeed, oral immunization of pigs with recombinant FaeG (rFaeG), the adhesin of the F4(K88) fimbriae of enterotoxigenic Esc...
In analogy to the corresponding measures of pseudorandomness for quaternary sequences introduced by Mauduit and Sárközy (for m-ary sequences) we introduce the well-distribution measure and correlation measure of order k for sequences over F4. Using any fixed bijection from F4 to the set of complex fourth roots of unity, we analyze the relation of these pseudorandomness measures for sequences ov...
Algebraic cryptanalysis usually requires to recover the secret key by solving polynomial equations. Faugère’s F4 is a well-known Gröbner bases algorithm to solve this problem. However, a serious drawback exists in the Gröbner bases based algebraic attacks, namely, any information won’t be got if we couldn’t work out the Gröbner bases of the polynomial equations system. In this paper, we in-dept...
The macrophage-specific antigen F4/80 has been localized in adult mouse bone and connective tissue. F4/80 positive cells form the centre of haemopoietic islands, line the periosteal and subendosteal bone surfaces and are a major component of connective tissue and the synovial membrane (presumptive type A cells). F4/80 is absent from fibroblasts, chondrocytes, osteoblasts, osteocytes, osteoclast...
