| The objectives of the study were toevaluate allelic frequencies and to test the associationof polymorphisms in the calpastatin (CAST) andμ-calpain (CAPN1) genes with meat tenderness in 3French beef breeds. A total of 1,114 Charolais, 1,254Limousin, and 981 Blonde d’Aquitaine purebred youngbulls were genotyped for 3 SNP in the CAST gene and4 SNP in the CAPN1 gene. Two of these markers, 1in each gene, can be found in Australian or Americancommercial genetic tests. Others have previously beenreported in American studies or are newly evidencedSNP. The quantitative traits studied were Warner-Bratzler shear force and a tenderness score evaluatedby trained sensory panels. All the SNP were informativein the 3 breeds. Associations of individual markersor haplotypes... |

| La production de la chaleur de 64 brebis de 7 types génétiques d’ovins a été mesurée en chambres respiratoires pour déterminer l’influence sur leurs dépenses énergétiques, de conditions climatiques bien contrôlées simulant les intempéries rencontrées en alpage. À 15°C, en air calme, la thermogenèse des brebis est en moyenne de 3,55 kcal/kgPo,75 par h. Une réduction de 5°C de la température ambiante ou un vent turbulent de 2 à 4 m/s entraîne une augmentation de 9% de la thermogenèse. Exposées à la pluie et au vent, les brebis s’immobilisent, la tête basse et le dos au vent. La thermogenèse des brebis Préalpes et Mourérous augmente rapidement (en 1,5 h) et fortement (+101% et +120% respectivement) et, dans une moindre mesure, celle des brebis Communes... |

| Within a population of Charolais young bulls, two extreme groups of longissimus thoracis muscle samples, classified according to Warner−Bratzler shear force (WBSF) of 55 °C grilled meat, were analyzed by 2D-electrophoresis. Muscle analyses were performed on 4 bulls of the “tender” group (WBSF = 27.7 ± 4.8 N) and 4 bulls of the “tough” group (WBSF = 41.2 ± 6.1 N), at 3 post-mortem times: D0, samples taken within 10 min post-mortem; D5 and D21, samples kept at 4 °C under vacuum during 5 and 21 days. Proteins of muscle samples were separated in two fractions based on protein solubility in Tris buffer: “soluble” and “insoluble”. Proteins of both fractions were separated by 2D-electrophoresis. Evolution of spots during the 3 post-mortem times was analyzed by... |

| Rats with carnitine deficiency due to trimethylhydrazinium propionate (mildronate) administered at 80 mg/100 g body weight per day for 10 days developed liver steatosis only upon fasting. This study aimed to determine whether the transient steatosis resulted from triglyceride accumulation due to the amount of fatty acids preserved through impaired fatty acid oxidation and/or from up-regulation of lipid exchange between liver and adipose tissue. In liver, mildronate decreased the carnitine content by ∼13-fold and, in fasted rats, lowered the palmitate oxidation rate by 50% in the perfused organ, increased 9-fold the triglyceride content, and doubled the hepatic very low density lipoprotein secretion rate. Concomitantly, triglyceridemia was 13-fold greater... |
