| In livestock the double-muscled phenotype is well known and has been selected in certain breeds, in order to increase carcass yield. Even though the chromosomal location of the gene responsible for the double-muscled phenotype in cattle has been known for a long time, the gene was identified more recently with studies in mice. In fact, mutations present in the growth factor myostatin gene cause the double-muscled phenotype. Myostatin is a negative regulator of muscle mass and plays a key role in muscle homeostasis. Myostatin also appears to be involved in the control of adipogenesis and osteogenesis. This review provides an update on the current state of the knowledge of myostatin and on the rational use of such knowledge in agronomy for meat production. |

| La mention "Agriculture Biologique" sur un produit garantit une manière de produire, mais l’obligation de résultats est limitée à la conformation et l’état d’engraissement de la carcasse, d’où des questions sur les qualités alimentaires du produit viande. |

| The major drawback of Ka band, operating frequency of the AltiKa altimeter on board SARAL, is its sensitivity to atmospheric liquid water. Even light rain or heavy clouds can strongly attenuate the signal and distort the signal leading to erroneous geophysical parameters estimates. A good detection of the samples affected by atmospheric liquid water is crucial. As AltiKa operates at a single frequency, a new technique based on the detection by a Matching Pursuit algorithm of short scale variations of the slope of the echo waveform plateau has been developed and implemented prelaunch in the ground segment. As the parameterization of the detection algorithm was defined using Jason-1 data, the parameters were re-estimated during the cal-val phase, during... |
