Bacterial communities colonize epithelial surfaces of most animals. Several factors, including the innate immune system, mucus composition, and diet, have been identified as determinants of host-associated bacterial communities. Here we show that the early branching metazoan Hydra is able to modify bacterial quorum-sensing signals. We identified a eukaryotic mechanism that enables Hydra to spec...

The structure of the title polymer, }[Mg(C6H14N2O6P2)(H2O)4]·0.5H2O} n , is based on centrosymmetric MgO6 octahedra, which are linked by [(piperazine-1,4-diium-1,4-di-yl)bis-(methyl-ene)]di-phospho-nate ligands, forming chains parallel to [1-1-1]. These chains are connected via hydrogen bonds primarily formed between the phospho-nate groups and water mol-ecules. The latter constitute four of th...

Hexamethyl-phospho-ramide (hmp), tetra-thio-tungstate(VI), silver sulfide and lanthanum(III) nitrate are self-assembled to form discrete cations one-dimensional poylmeric anionic chains [AgWS(4)](n) (n) (-) in the title compound, {[La(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgWS(4)]}(n). The central La atom in the cation is coordinated by eight O atoms from two nitrate and four hmp ligands. Together wit...

The activity of human replication protein A (RPA) in DNA replication and repair is regulated by phosphorylation of the middle RPA2 subunit. It has previously been shown that up to nine different N-terminal residues are modified in vivo and in response to genotoxic stress. Using a novel antibody against phospho-Ser(29), a moiety formed by cyclin-Cdk, we observed that RPA2 was phosphorylated duri...

O presente artigo aborda a questão das dificuldades enfrentadas pelo aluno com deficiência auditiva, que faz uso de implante coclear, em seu processo alfabetização e letramento, considerando sua característica ser uma criança oralizada não usuária da Língua Brasileira Sinais (LIBRAS). Esse trabalho se fundamentou teoricamente nas autoras Magda Soares, Maria Cristina Fonseca Redondo Josefina Mar...
