It has been shown by a number of observers that the administration of iodides both to dogs and to human beings causes an increase in the output of nitrogen in the urine. One of the earliest observers (1) working with dogs showed that this was in part at the expense of the nitrogen excreted in the feces, but that the total amount of nitrogen excreted was none the less increased. We have been abl...

We measured carbon, nitrogen, protein, bacterial and microalgal abundance, and minerals p e c ~ f ~ c surface area m sediments from the feeding zone of undisturbed Saccoglossus korualewskyi, as well as In their fresh egesta. Comparison of results using surficial material (> 1 mm) and the top 3 mm of sediments indicated ingestion of surficial material by the enteropneusts. Assuming the surficial...

background outer membrane protein d (pd) is a highly conserved and stable protein in the outer membrane of both encapsulated (typeable) and non-capsulated (non-typeable) strains of haemophilus influenzae. as an immunogen, pd is a potential candidate vaccine against non-typeable h. influenzae (nthi) strains. objectives the aim of this study was to determine the cytokine pattern and the opsonic a...

Four treatments were assigned to determine the effects of dietary potential digestible fiber (pdF) and crude protein (CP) levels in mid lactating Holstein cows on milk production and nitrogen efficiency. Sixteen primiparous (n=8) and multiparous (n=8) Holstein cows (body weight (BW)=546±72 kg; days in milk (DIM)=118±50 day) were allocated to one of four diets in balanced randomized complete des...

1. Comparisons of the nitrogen content of TMV-infected and uninfected tobacco leaf discs at various times after inoculation show that virus synthesis is associated with a net increase in protein content. This excess protein is due to: (a) TMV, (b) an excess in insoluble protein which develops soon after inoculation and ends about 100 hours before cessation of TMV synthesis, and (c) an excess in...

the aim of this study was to investigate the genotype effect on nitrogen remobilization and its relationship with yield and grain protein concentration in genotypes of wheat during grain filling. twelve wheat cultivars different in origin and varying with grain yield and grain protein percentage were selected. a randomized complete block design was used. plants were harvested at anthesis and ma...
