The Home Library

Too often a home library is like the purple cow; it does not exist. True, many homes possess a Bible, a hymn book, and a set of subscription books bought from a too-persuasive book agent by some credulous ancestor; but if stone walls do not a prison make, certainly books do not necessarily make a library

Books - Why Not?

Christmas is coming. Many of us are thinking over carefully, even anxiously, what will make the best gifts for the children. Candy and sweets too often result in regrets and castor oil; toys - yes. they are exciting for a time, but too many mean distraction and tend to develop an inability to concentrate for any length of time. Wrecks and breakage come quickly. Then why not books, at least one or two, in place of half the candy and half the toys

DEMAND FOR NUTRIENTS: THE HOUSEHOLD PRODUCTION APPROACH

The household production approach is used to characterize the household's preference toward nutrients in food consumption. Elasticities of substitution and Hicksian price elasticities are estimated, price- and expenditure-nutrient elasticities are calculated. Results show that protein is the most expensive nutrient, and that nutrients played an important role in determining households' food consumption.Consumer/Household Economics, Demand and Price Analysis, Food Consumption/Nutrition/Food Safety,

Effects of Daily Zinc, Daily Multiple Micronutrient Powder, or Therapeutic Zinc Supplementation for Diarrhea Prevention on Physical Growth, Anemia, and Micronutrient Status in Rural Laotian Children: A Randomized Controlled Trial.

ObjectivesTo evaluate the optimal zinc supplementation strategy for improving growth and hematologic and micronutrient status in young Laotian children.Study designIn total, 3407 children aged 6-23 months were randomized to receive either daily preventive zinc tablets (7 mg/d), high-zinc, low-iron micronutrient powder (10 mg/d zinc, 6 mg/d iron, and 13 other micronutrients), therapeutic zinc supplementation for diarrhea (20 mg/d for 10 days per episode), or daily placebo powder; all were followed for ~9 months. Anthropometry, hemoglobin, zinc, and iron status were assessed at baseline and endline. Analyses were by intention-to-treat, using linear and modified Poisson regression.ResultsAt baseline, mean (±SD) age was 14.2 ± 5.1 months and stunting and anemia prevalence were 37.9% and 55.6%, respectively. At endline, zinc deficiency in the preventive zinc (50.7%) and micronutrient powder (59.1%) groups were significantly lower than in the therapeutic zinc (79.2%) and control groups (78.6%; P < .001), with no impact on stunting (37.1%-41.3% across the groups, P = .37). The micronutrient powder reduced iron deficiency by 44%-55% compared with other groups (P < .001), with no overall impact on anemia (P = .14). Micronutrient powder tended to reduce anemia by 11%-16% among children who were anemic at baseline (P = .06).ConclusionsDespite improving zinc status, preventive zinc and micronutrient powder had no impact on growth. The micronutrient powder improved iron status and tended to reduce anemia among the subset of previously anemic children.Trial registrationClinicalTrials.govNCT02428647

Rod saturation in b-wave of the rat electroretinogram under two different anesthetics

B-wave increment threshold experiments in the rat show that "rod saturation" occurs at different background levels with different anesthetics. Rod saturation builds up over the first 60 sec of light adaptation in pentobarbital anesthetized but not in urethane anesthetized animals. These and other findings suggest that "rod saturation" can occur when the rod photoreceptors themselves are not saturated.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/24962/1/0000389.pd
