—To optimize the essential amino acid (EAA) profile for mature striped bass Morone saxatilis, diets with graded levels of three essential amino acids—lysine (Lys), threonine (Thr), and total sulfur amino acids (Tsaa) methionine and cysteine—were fed to 4-year-old striped bass females. The relative concentrations of these EAAs were maintained in ratios similar to those determined from the analys...

Sources of variation in Finnish Landrace and Targhee birth weights from pregnancies following natural matings and intra-breed, inter-breed and 2-breed embryo transfers were studied. Birth weights were recorded on 94 lambs from naturally mated ewes and 117 transfer lambs. Two analyses were done, one on observed weights, and one on deviations of observed weights from weights predicted from litter...

BACKGROUND Obesity, the condition of excessive accumulation of fat is a poorly understood disorder and is a risk factor for type II diabetes, hypertension, and hyperlipidaemia. Recently, a putative mouse obese gene was cloned and its product, termed ob protein, was shown to be involved in the regulation of body weight. MATERIALS AND METHODS Bacterial and insect cells were used for expression ...

Free methionine levels in rin and normal tomato fruits were determined microbiologically. Similar levels (1750 mug/100 g fresh weight) for mature green fruits of both rin and a normal isogenic line suggest that the lack of ripening of rin fruits is not due to low methionine levels. Methionine levels of mature green rin and normal fruits were 1750 mug/ 100 g fresh weight. Normal fruits ripened e...
