Lactobacillus pentosus B231 Isolated from a Portuguese PDO Cheese: Production and Partial Characterization of Its Bacteriocin.
Probiotics Antimicrob Proteins 6 , 95-104, (2014) Bacteriocin B231 produced by Lactobacillus pentosus, isolated from an artisanal raw cow's milk protected designation of origin Portuguese cheese, is a small protein with an apparent relative mass of about 5 kDa and active against a large number of Listeria mo... |

Glycan complexity dictates microbial resource allocation in the large intestine.
Nat. Commun. 6 , 7481, (2015) The structure of the human gut microbiota is controlled primarily through the degradation of complex dietary carbohydrates, but the extent to which carbohydrate breakdown products are shared between members of the microbiota is unclear. We show here, using xy... |

Chiral separation of D/L-aldoses by micellar electrokinetic chromatography using a chiral derivatization reagent and a phenylboronic acid complex.
Anal. Bioanal. Chem 407 , 6201-6, (2015) A novel method was developed for D/L-isomeric separation of aldopentoses and aldohexoses as their (S)-(+)-4-(N,N-dimethylaminosulfonyl)-7-(3-aminopyrrolidin-1-yl)-2,1,3-benzoxadiazole derivatives using phenylboronate buffer containing sodium dodecyl sulfate a... |

Using substrate engineering to harness enzymatic promiscuity and expand biological catalysis.
Nat. Chem. Biol. 2 , 724-8, (2006) Despite their unparalleled catalytic prowess and environmental compatibility, enzymes have yet to see widespread application in synthetic chemistry. This lack of application and the resulting underuse of their enormous potential stems not only from a wariness... |

Functions of Armigeres subalbatus C-type lectins in innate immunity.
Insect Biochem. Mol. Biol. 52 , 102-14, (2014) C-type lectins (CTLs) are a superfamily of calcium-dependent carbohydrate binding proteins containing at least one carbohydrate-recognition domain (CRD) and they are present in almost all metazoans. Insect CTLs may function as pattern-recognition receptors an... |

Aberrant expression of claudin-4 and -7 in hepatocytes in the cirrhotic human liver.
Med. Mol. Morphol. 48(1) , 33-43, (2015) The liver comprises hepatocytes and non-parenchymal cells such as bile duct epithelial cells. Claudin-4 and -7 are not expressed in hepatocytes under physiological conditions. It was reported that claudin-7 increased in human pulmonary fibroses. We therefore ... |

Transplantation of human stem cell-derived hepatocytes in an animal model of acute liver failure.
Surgery 158 , 349-59, (2015) Hepatocyte cell transplantation can be life-saving in patients with acute liver failure (ALF); however, primary human hepatocyte transplantation is limited by the scarcity of donor hepatocytes. We investigated the effect of stem cell-derived, hepatocyte-like ... |

Anti-tumour effect of metformin in canine mammary gland tumour cells.
Vet. J. 205 , 297-304, (2015) Metformin is an oral hypoglycaemic drug used in type 2 diabetes. Its pharmacological activity reportedly involves mitochondrial respiratory complex I, and mitochondrial respiratory complex inhibitors have a strong inhibitory effect on the growth of metastatic... |

HIV-1 pathogenicity and virion production are dependent on the metabolic phenotype of activated CD4+ T cells.
Retrovirology 11 , 98, (2015) HIV-1, like all viruses, is entirely dependent on the host cell for providing the metabolic resources for completion of the viral replication cycle and the production of virions. It is well established that HIV-1 replicates efficiently in activated CD4+ T cel... |
