The population dynamics of Heterodera glycines as influenced by alachlor, fenamiphos, and ethoprop alone and in herbicide-nematicide combinations were studied in the field. Numbers of H. glycines juveniles and eggs were higher at midseason and harvest where nematicides were applied.

Effect of estradiol on the amino acid-accepting activity of uterine tRNAs and their participation in protein synthesis.

Estradiol (E2) induces a complementary increase in both the amount of mRNA and the rate of translation of the mRNA in the uterus of ovariectomized mature rats. The mechanism of the translational effect was evaluated by measuring the functional capacity of uterine tRNA isolated from control, E2 (1 h)- and E2 (14 h)-treated ovariectomized rats to support amino acid acceptor activity and uterine protein synthesis. The specific amino acid acceptor activity (SAA) of deacylated tRNA for 18 individual amino acids was determined using a tRNA-dependent rat liver tRNA synthetase preparation.

Ribosome-associated estradiol-binding components in the uterus and their relationship to the translational capacity of uterine ribosomes.

Estradiol transiently increases the rate of peptide elongation on uterine ribosomes from ovariectomized mature rats during the first 2 h after hormone injection, suggesting the existence of direct or indirect estradiol receptor interaction with ribosomes. Characterization of estradiol-binding components on isolated uterine ribosomes, microsomes, and cytosol under identical assay conditions indicated that microsomes and cytosol contain estradiol-binding components with similar affinities for estradiol (Kd = 0.5 nM) and sucrose gradient sedimentation characteristics (3.

Effects of diet concentrate level and sodium bicarbonate on site and extent of forage fiber digestion in the gastrointestinal tract of wethers.

Four adult wethers (45 kg) with permanent ruminal and abomasal cannulae were used in a repeated measures Latin-square arrangement of treatments to quantitate the effects of diet concentrate level and sodium bicarbonate (NaHCO3) on site and extent of forage fiber digestion in the gastrointestinal tract. Experimental diets consisted of Kentucky-31 tall fescue hay, soybean meal and a semi-purified concentrate mixture in ratios of 95:5:0, 76:4:20, 57:3:40 and 38:2:60; NaHCO3 represented 0 or 7.5% of the concentrate mixture.

Isolation of a precursor and a nascent chain form of glucose-6-phosphate dehydrogenase from rat uterus and regulation of precursor processing by estradiol.

SDS-polyacrylamide gel electrophoresis of anti-glucose-6-phosphate dehydrogenase immunoprecipitates from radiolabeled uterine tissue extracts previously revealed three proteins: A, B and C, which were tentatively identified as a 60-64 kDa precursor form, a 57 kDa predominant form, and a 40-42 kDa nascent peptide form of the enzyme, respectively. A peptide-mapping technique was used to examine structural homologies among A, B and C. Following the labeling of uterine proteins with [35S]methionine, labeled proteins A, B and C were isolated by immunoprecipitation and electrophoresis.

National survey of hospital pharmacy facilities: adequacy of facilities and changes planned.

The adequacy of existing space allocations for hospital pharmacy facilities and planned changes are described. A 12-page questionnaire was sent in July 1982 to the chief pharmacists in a random sample of 1846 hospitals in the United States stratified by 10 hospital types. The respondents in each hospital type and size were categorized by their perceived adequacy of existing space for pharmacy facilities and their plans for adding pharmacy functions and staff.

National survey of hospital pharmacy facilities: space allocations and functions.

Space allocations for hospital pharmacies and the demand on these facilities in terms of the external environment and functions performed are described. A 12-page questionnaire was sent in July 1982 to the chief pharmacists in a random sample of 1846 hospitals in the United States stratified by 10 hospital types. The respondents in each hospital type were categorized by variables characterizing the external environment.

National survey of hospital pharmacy facilities: planning and design experience.

Recent major renovation or construction programs of hospital pharmacy facilities and pharmacists' involvement in the planning process for those new facilities are described. A 12-page questionnaire was sent in July 1982 to the chief pharmacists in a random sample of 1846 hospitals in the United States stratified by 10 hospital types. The percentage of hospitals of each type involved in an ongoing or recent (within the preceding 10 years) major renovation or construction project of all or part of the pharmacy was determined.

National survey of hospital pharmacy facilities: introduction.

This paper introduces three articles that report results of a national survey of hospital pharmacy facilities conducted in July 1982. A historical perspective of pharmacists' involvement in facilities planning and examples of internal and external factors influencing the optimal design of hospital pharmacies are presented. The survey aimed to identify and describe existing hospital pharmacy facilities, the adequacy of existing facilities, the anticipated need for facilities, and the processes used for planning facilities.

Platelet aggregation in non-insulin-dependent diabetes is associated with platelet fatty acids.

Platelet aggregation was measured in 15 patients having non-insulin-dependent diabetes mellitus (NIDDM) at the time of diagnosis and after three months of dietary treatment. Mean fasting plasma glucose fell from 13.0 to 8.

Influence of Selected Cultural Practices on Winter Survival of Pratylenchus brachyurus and Subsequent Effects on Soybean Yield.

Planting date of soybean, Glycine max, influenced winter survival of Pratylenchus brachyurus in microplots at two locations in North Carolina. Delayed planting resulted in a linear decrease (P = 0.05) in the numbers of P.

Influence of Planting Date on Population Dynamics and Damage Potential of Pratylenchus brachyurus on Soybean.

Planting date was used as a variable to determine the effects of time and different environmental conditions on the population dynamics and damage potential of Pratylenchus brachyurus on soybean at two locations in North Carolina. An initial population slightly less than the damage threshold (275 nematodes/500 cm(3) soil) was used to minimize the influence of host damage on this nematode's population dynamics and to gain greater precision in characterizing factors which influence the damage potential of P. brachyurus to soybean.

Overestimation of Yield Loss of Tobacco Caused by the Aggregated Spatial Pattern of Meloidogyne incognita.

Overestimation of yield loss caused by Meloidogyne incognita on tobacco was calculated as a function of the statistical frequency distribution of sample counts. Sampling frequency distributions were described by a negative binomial model, with parameter k, and the resulting probability generating function was used to calculate discrete damage probabilities. Negative binomial damage predictions were compared to mean-density estimates of damage.

Inhibition of the aminoacylation of selected tRNA molecules by an estrogen-regulated factor on uterine ribosomes. Regulation of aminoacylation of tRNA by estrogens.

Administration of estradiol to ovariectomized mature rats for 1 h induces a transient increase in the peptide elongation rate on uterine ribosomes. An inhibitor of the peptide elongation rate, which appears to be regulated by estrogen treatment in vivo, can be extracted from ribosomes of estrogen-deprived rats. The extracted inhibitor or a native inhibitor-ribosome complex affects the rate of the peptide elongation reaction in a uterine cell-free protein synthesis system by inhibiting the ability of selected tRNAs in the assay to be charged with amino acids by their respective aminoacyl-tRNA synthetases.

Serum and liver enzymes of collagen synthesis in hepatic murine schistosomiasis mansoni.

Serum galactosylhydroxylysyl glucosyltransferase (S-GGT), liver galactosylhydroxylysyl glucosyltransferase (L-GGT), liver hydroxylysyl galactosyltransferase (L-GGal-T) and liver prolyl hydroxylase (L-PH) activities were measured in CF1 female mice each week for 10 weeks after infection with Schistosoma mansoni (50 cercariae per mouse). None of the enzyme activities measured were significantly increased in the first six weeks following the infection. However, the activities increased thereafter reaching a maximum of seven-fold for S-GGT, five-fold for L-GGT, three-fold for L-GGal-T and ten-fold for L-PH compared with control animals.
