Matters of development and experience: Evaluation of dog and human emotional expressions by children and adults.

Emotional facial expressions are an important part of across species social communication, yet the factors affecting human recognition of dog emotions have received limited attention. Here, we characterize the recognition and evaluation of dog and human emotional facial expressions by 4-and 6-year-old children and adult participants, as well as the effect of dog experience in emotion recognition. Participants rated the happiness, anger, valence, and arousal from happy, aggressive, and neutral facial images of dogs and humans.

Macronutrient and energy database for the 1995 Exchange Lists for Meal Planning: a rationale for clinical practice decisions.

For more than 50 years the exchange lists have been one method of meal planning for persons with diabetes as well as for those on weight-loss regimens. Little research has been conducted, however, concerning the methodologic basis of the system or its clinical effectiveness. Justification for specific food inclusions and general food groupings for the 1995 revision of the Exchange Lists for Meal Planning is provided by a database of foods and associated energy and macronutrient values.

Psychiatric disorder in a familial 15;18 translocation and sublocalization of myelin basic protein of 18q22.3.

Two related patients with similar clinical features consisting of a few dysmorphic signs and psychiatric disturbance were reported to have a partial trisomy of chromosomes 15(pter-q13.3) and 18(q23-qter) deriving from a familial translocation t(15;18). One patient is affected by bipolar disorder and the other by schizoaffective disorder.

Involvement of carbonic anhydrase in ammonia flux across rumen mucosa in vitro.

Carbonic anhydrase activity in mucosa of the sheep rumen wall was completely inhibited by acetazolamide and ethoxyzolamide. This inhibition significantly reduced ammonia flux across mucosal discs in vitro but was ineffective if short-chain fatty acids were present in the bathing solution. The findings are discussed in relation to the mechanism of ruminal ammonia absorption.

Toothpastes.

It is well known that plaque is the main cause of caries and parodontopathies, which puts the role of toothpastes as an important means of prevention of odontopathies to the foreground. Toothpastes can be more or less oriented towards having a particular effect, such as cleaning, anticaries effect, antimicrobial effect or inhibition of the formation of tartar. Toothpastes contain substances which promote dental health, such as abrasives (silicium dioxide, brushite, calcite, calcite and aragonite, gibbsite etc.

Influence of short-chain fatty acids on ammonia absorption across the rumen wall in sheep.

The effects of short-chain fatty acids (SCFA) on ammonia net absorption from the sheep rumen in vivo and on ammonia transport across rumen wall mucosa in vitro were studied. Ammonia net absorption was directly, though in a non-linear manner, correlated with the SCFA concentration in the artificial rumen fluid. Almost 70% of total ammonia absorption was dependent upon the presence of SCFA when 12 mmol l-1 ammonia and 67.

Understanding the use of the exchange lists for meal planning in diabetes management.

The Exchange Lists for Meal Planning has been in existence since 1950 and was updated in 1976 and 1986. The lists were designed to provide a universal system for the nutrition management of diabetes mellitus. The current edition emphasizes a high-carbohydrate, low-fat diet and is widely used by persons with diabetes and by diabetes educators.

Ammonia absorption from the isolated reticulo-rumen of sheep.

In fistulated sheep (50-60 kg live weight) the absorption of ammonia from the reticulo-rumen in vivo was studied applying the technique of the temporarily isolated and washed reticulo-rumen. It was found that, at ammonia concentrations between 3 and 18 mM, ammonia efflux and ammonia net absorption were linearly related to the ammonia concentration in the artificial rumen fluid, whereas influx of ammonia nitrogen from endogenous sources remained almost constant. When the concentration of unionized NH3 was changed at the ratio 1:10:76 by varying the pH from 5.

Failure of 1,25-(OH)2-vitamin D3 to affect calcium flux across sheep rumen wall mucosa in vitro.

Isolated pieces of mucosa from the sheep rumen wall mounted between half-chambers were used in conventional incubation studies (1 h, 39 degrees C) with buffer solutions resembling rumen fluid (= mucosal fluid) and extracellular fluid (= serosal fluid), respectively. The mucosal-to-serosal (ms) flux of calcium was studied by use of 45CaCl2 with and without 1,25-(OH)2-vitamin D3 in the serosal incubation fluid. Different concentrations of the vitamin had no effect on Ca ms-flux.

Concentrations of volatile fatty acids and acetate production rates in the forestomachs of grazing camels.

1. Concentration profiles of volatile fatty acids (VFA), fluid volumes and turnover rates, and acetate production rates were measured in two different seasons in the forestomachs of four fistulated dromedary camels grazing in the Kenyan thornbush savannah. 2.

Flux of calcium across the sheep rumen wall in vivo and in vitro.

Experiments were carried out in vivo and in vitro to study the flux of Ca2+ across the sheep rumen wall. Buffer solutions with five different Ca2+ concentrations in the range 0.2-3.

Flux of inorganic phosphate across the sheep rumen wall in vivo and in vitro.

Experiments were done in vivo and in vitro to study the flux of inorganic phosphate (P1) across the rumen wall in sheep. The technique of the temporarily isolated and washed reticulo-rumen was applied to measure P1 net flux at nine different P1 concentrations in the buffer solutions introduced into the reticulo-rumen for 1 h. Six sheep were either P replete (4.

Effect of bezafibrate and colestyramine in patients with primary hypercholesterolemia.

40 patients with primary hypercholesterolemia were included in a randomized cross-over trial comparing effects and tolerance of bezafibrate (Cedur) (200 mg t.i.d.

Exchange lists: revised 1986.

A committee composed of members of The American Dietetic Association and the American Diabetes Association has revised Exchange List for Meal Planning. Changes were made, as deemed necessary, on the basis of nutritional recommendations for persons with diabetes as understood in 1986. Major changes include rewriting the text to make it more useful in the education of persons with diabetes; changing the order of the exchange lists to emphasize a high-carbohydrate, high-fiber diet, as well as to better reflect the order of foods in menu planning; adding symbols to foods high in fiber and sodium; changing nutritive values for the starch/bread and fruit lists; adding lists of combination foods, free foods, and foods recommended only for occasional use; developing a data base; and initiating a plan for field testing and evaluation.
