Consumption of Ultra-Processed Foods Is Associated with Free Sugars Intake in the Canadian Population.

Excess sugar consumption can lead to noncommunicable diseases (NCDs) such as type 2 diabetes. Increasingly, ultra-processed foods (UPF) are suspected to be great contributors to free sugars intake in the population's diet. Thus, the aim of this study was to investigate the association between UPF consumption and free sugars intake in the Canadian population.

Eimeria tenella enolase and pyruvate kinase: a likely role in glycolysis and in others functions.

Two cDNA codings for glycolytic enzymes were cloned from a cDNA library constructed from the schizont stage of the avian parasite Eimeria tenella. Enolase and pyruvate kinase cDNA were fully sequenced and compared with sequences of enzymes from other organisms. Although these enzymes were already detected in the sporozoite stage, their expression was enhanced during the first schizogony in accordance with the anaerobic conditions of this part of the life cycle of the parasite.

Study of proteins associated with the Eimeria tenella refractile body by a proteomic approach.

Refractile bodies (RB), whose function is still unknown, are specific structures of Eimeriidae parasites. In order to study their proteome, RB were purified from Eimeria tenella sporozoites by a new procedure using a reversible fixation followed by centrifugation. RB proteins were resolved by two-dimensional electrophoresis.

The heat shock protein 90 of Eimeria tenella is essential for invasion of host cell and schizont growth.

The 90-kDa heat shock proteins (Hsp90) are important for stress tolerance, for newly synthesised protein folding and for the growth of various organisms. Participation of Hsp90 in the development of Apicomplexa, notably in Plasmodium falciparum and Toxoplasma gondii, has been proven. In this work, the importance of Hsp90 for Eimeria tenella, which is responsible for avian caecal coccidiosis, was studied.

Towards a reference map of Eimeria tenella sporozoite proteins by two-dimensional electrophoresis and mass spectrometry.

Eimeria tenella is a parasite of great importance as a disease causing agent in the poultry industry. Until recently, biological studies have focused on specific proteins, some of which play an important role in the parasite life cycle. Post-genomic studies will make it possible to understand the complexity of the parasites and their interactions with host cells.

Production of a functional chicken single-chain variable fragment antibody derived from caecal tonsils B lymphocytes against macrogamonts of Eimeria tenella.

Avian coccidiosis is due to a protozoan intracellular parasite belonging to the genus Eimeria which multiplies in the intestine of the host. In order to identify Eimeria antigens which reflect the natural avian humoral immune response, chicken hybridomas were produced by fusion of myeloma MuH1 with B lymphocytes from Eimeria tenella infected chicken. B lymphocytes used for fusions were isolated from tonsils at the basis of caeca where the parasite develops.

Gene discovery in Eimeria tenella by immunoscreening cDNA expression libraries of sporozoites and schizonts with chicken intestinal antibodies.

Specific antibodies were produced ex vivo from intestinal culture of Eimeria tenella infected chickens. The specificity of these intestinal antibodies was tested against different parasite stages. These antibodies were used to immunoscreen first generation schizont and sporozoite cDNA libraries permitting the identification of new E.
