The efficiency of traditional, intermediate and improved parboilers was compared through their effects on certain physical and cooking quality traits. Two varieties (NERICA 4 and Gambiaka) commonly cultivated and consumed in Benin were used. Results showed that the traditional parboiler had the highest level of heat-damaged grains (90%) with the improved equipment having the least (17%). The improved and intermediate parboiling technology produced grains of comparable hardness (4 kg and 6 kg, respectively, for Gambiaka and NERICA 4) while the traditional method resulted in a sample with the least hardness for both Gambiaka (4 kg) and NERICA 4 (3 kg). The improved method and the intermediate technology using wooden sticks at the bottom of the vessel had higher water uptake (2.97 ml/grain) and grain swelling ratios (5.41) as compared to the traditional and intermediate methods using a container with a perforated bottom.

The purpose of this study was to investigate the imputation error and loss of reliability of direct genomic values (DGV) or genomically enhanced breeding values (GEBV) when using genotypes imputed from a 3,000-marker single nucleotide polymorphism (SNP) panel to a 50,000-marker SNP panel. Data consisted of genotypes of 15,966 European Holstein bulls from the combined EuroGenomics reference population. Genotypes with the low-density chip were created by erasing markers from 50,000-marker data. The studies were performed in the Nordic countries (Denmark, Finland, and Sweden) using a BLUP model for prediction of DGV and in France using a genomic marker-assisted selection approach for prediction of GEBV. Imputation in both studies was done using a combination of the DAGPHASE 1.1 and Beagle 2.1.3 software. Traits considered were protein yield, fertility, somatic cell count, and udder depth. Imputation of missing markers and prediction of breeding values were performed using 2 different reference populations in each country: either a national reference population or a combined EuroGenomics reference population. Validation for accuracy of imputation and genomic prediction was done based on national test data. Mean imputation error rates when using national reference animals was 5.5 and 3.9% in the Nordic countries and France, respectively, whereas imputation based on the EuroGenomics reference data set gave mean error rates of 4.0 and 2.1%, respectively. Prediction of GEBV based on genotypes imputed with a national reference data set gave an absolute loss of 0.05 in mean reliability of GEBV in the French study, whereas a loss of 0.03 was obtained for reliability of DGV in the Nordic study. When genotypes were imputed using the EuroGenomics reference, a loss of 0.02 in mean reliability of GEBV was detected in the French study, and a loss of 0.06 was observed for the mean reliability of DGV in the Nordic study. Consequently, the reliability of DGV using the imputed SNP data was 0.38 based on national reference data, and 0.48 based on EuroGenomics reference data in the Nordic validation, and the reliability of GEBV using the imputed SNP data was 0.41 based on national reference data, and 0.44 based on EuroGenomics reference data in the French validation.

We have investigated the influence of a single oral administration of indomethacin on blood glucose, plasma free fatty acids (FFA), alpha-amino-nitrogen, insulin and glucagon concentrations in young healthy subjects. Two groups of 6 subjects were studied, the first received a standardized 500 kcal mixed meal without any previous drug administration (controls) whereas the second group received 50 mg indomethacin 2 h before ingesting an identical meal. Plasma indomethacin concentration reached its maximum (2.36 +/- 0.36 micro g/ml) 15 min after administration and declined to 0.45 +/- 0.04 micro g/ml after 2 h. Indomethacin ingestion was followed by a significant increase in blood glucose and plasma FFA reaching their maximum value at 45 min and returning to basal levels at 120 min. No simultaneous changes in plasma alpha-amino-nitrogen, insulin or glucagon levels were detected during this period. The meal was followed by a rise in blood glucose and plasma insulin as well as by a decrease in plasma FFA concentration. No significant differences were detected between the controls and the subjects receiving indomethacin. In controls, the meal was followed by a rise in plasma alpha-amino-nitrogen and a modest although significant increase in glucagon levels. In indomethacin-treated subjects, the increment of alpha-amino-nitrogen was less marked and the increase in plasma glucagon was not observed. Thus, indomethacin by itself can exert several metabolic effects; however, it does not deteriorate the blood glucose or insulin profile after a regular meal. The present work is the first to demonstrate that an inhibitor of prostaglandin synthesis inhibits the plasma glucagon rise occurring after a physiological stimulus such as a normal meal. On the basis of previous in vitro experiments, we suggest that this effect results from an inhibition of glucagon secretion by the PG synthesis inhibitor. [less ▲]

Hepatocytes isolated from fetal quail livers (Coturnix coturnix japonica) were cultured in vitro. Their capacity to metabolize drugs and xenobiotics was explored with typical cytochrome P450 substrates: ethoxycoumarin (known to be metabolized by several P450s), ethoxyresorufin (essentially dealkylated by P450IA1), and testosterone (specifically hydroxylated at several positions by several P450s). The cells could be kept metabolically active in culture for at least 4 days. Their drug-metabolizing activities were inducible by the usual P450 inducers, like phenobarbital and benzanthracene, but also by Aroclor 1254, a PCB mixture. The results obtained indicate that this experimental model could certainly be very helpful in ecotoxicological studies. [less ▲]

Inoculation with Actinomyces pyogenes and administration of prostaglandin (PG) F-2alpha were used to induce late embryonic mortality (LEM) in heifers (n = 8) on Days 30-38 of pregnancy in order to compare the profile for bovine pregnancy associated glycoprotein 1 (PAG1), progesterone and 15-keto-13,14-dihydro-PGF(2alpha) (PGFM). Two pregnant heifers were used as controls. Inoculation into the uterine body caused LEM, as established by ultrasonography in each heifer within 24 h of treatment. When the inoculum was injected into the first part of the cervix, LEM occurred in one of two heifers (Heifer A) between 48 and 72 h after treatment. Similarly, PGF(2alpha) treatment caused LEM in three of four heifers. In six of eight heifers, PAG1 started to decrease steadily when it was accompanied by the subsequent death of the embryo. Inoculation through the cervix caused luteolysis in three of four heifers within 6-10 days after induction. After induction of LEM, PGFM concentrations showed a two to 3.8 fold increase in three of four heifers during the following six days, and from that time changed within normal ranges. The results of this study indicate that a PAG1 assay may provide an alternative method to ultrasonography for determining LEM in the cow. [less ▲]

Histone deacetylase (HDAC) inhibitors are a novel class of promising anti-cancer agents. Little information is available on the capacity of structurally different HDAC inhibitors to induce terminal cell differentiation in different cell types in relation to enzyme inhibition and subtype selectivity. Consequently, the aim of this study was to provide a comprehensive comparison of these effects. New biarylalanine inhibitors of HDAC were synthesized and compared to a series of standard inhibitors from different laboratories. Chromatographically purified rat liver and immunoprecipitated FLAG-tagged recombinant human HDACs were used as sources of HDAC activity. Enzyme inhibition was studied using a fluorescent substrate and its conversion was monitored by high-performance liquid chromatography. The ability to induce cell differentiation was compared in murine (Friend DS-19) and human (K562) erythroleukemic cell lines, and was quantified by benzidine staining. Inhibition of cell proliferation was evaluated by cell counting. All HDAC inhibitors were identified as potent inhibitors of erythroleukemic cell proliferation. However, we observed a complex pattern of differentiation induction: structurally similar inhibitors resulted in disparate activity profiles, whereas similar profiles were detected within distinct structural classes. Among the newly synthesized biarylalanine compounds, a 3'-methoxy derivative was identified as a very effective inducer of terminal cell differentiation. We conclude that investigation of subtype selectivity of selected HDAC inhibitors does not provide a clear link between selectivity and the observed cellular activity profile. The predictive value of in vitro HDAC inhibition assays for identifying anti-proliferative compounds has been emphasized. [less ▲]

The slenderness of plated structures together with a generalised use of high strength steel leads to a great importance of stability phenomena. The practical way to deal with such problems is to use rules proposed in design codes. A common alternative to design codes is the use of non linear finite element simulations. One of the most sensitive point in these simulations is the choice of the initial imperfections to be introduced in the model. The present paper discusses the effect of initial imperfections on the calculated collapse load. Several parameters are considered (shape, magnitude and direction). Results of numerical simulations are also compared with those of a design using Eurocode 3 or ECCS Recommendations. Two cases of plate geometry are studied (plate with one single stiffener and plate with multiple stiffeners). [less ▲]

REASONS FOR PERFORMING STUDY: Pulmonary capillary stress failure, largely as a result of high pulmonary vascular pressures, has been implicated in the aetiology of EIPH. However, the role of the respiratory system in determining the magnitude of EIPH has received little attention. HYPOTHESIS: Horses breathing a gas of greater density than air will exhibit greater transmural pulmonary arterial pressures (TPAP) and more severe EIPH, and horses breathing a gas of lower density than air will exhibit lower TPAP and less severe EIPH, both compared with horses breathing air. METHODS: Following a warm-up, 8 Thoroughbred horses were exercised for 1 min at 10, 11 and 12 m/sec (5 degrees incline) breathing air or 21% oxygen/79% helium or 21% oxygen/79% argon in a randomised order. Heart rate, respiratory rate, pulmonary arterial pressure and oesophageal pressure were measured during exercise. Bronchoalveolar lavage fluid (BALF) was collected from the dorsocaudal regions of the left and right lungs 40 min post exercise and red blood cell (RBC) counts were performed. RESULTS: The exercise tests induced mild EIPH. Maximum changes in oesophageal pressure were lower on helium-oxygen compared to argon-oxygen (P<0.001). TPAP and median RBC counts did not differ between gas mixtures. BALF RBC counts from the left lung correlated with counts from the right lung (P<0.0001). However BALF RBC counts from the left lung were higher than those from the right lung (P = 0.004). CONCLUSION: As alterations in pulmonary arterial and oesophageal pressure caused by changes in inspired gas density were of similar magnitude, TPAP remained unchanged and there was no significant effect on EIPH severity. POTENTIAL RELEVANCE: Manipulations that decrease swings in intrapleural pressure may only decrease the degree of EIPH in horses severely affected by the condition [less ▲]

This study aimed at measuring the functional consequences and the pulmonary cytology changes following a simulation of pulmonary haemorrhage. Pulmonary function tests including lobeline-induced hyperventilation, cytology of tracheo-bronchial wash (TBW) and thoracic radiographs were performed before, as well as 1, 7, 14 and 28 days after, the instillation of 300 ml of blood into the lungs of 4 horses deemed free of exercise-induced pulmonary haemorrhage (Group 1). Control data (Group 2) were obtained by instilling the same volume of saline into the lungs of the same horses in a crossover design (control). The instillation of blood or saline resulted in an increase in the number of neutrophils in the TBW. Thoracic radiographs showed increased opacity in the caudodorsal region of the lungs in 4/4 (Day 1) and 2/4 horses (Day 7), in Group 1, and in 2/4 (Day 1) and 0/4 horses (Day 7) in the control group. These changes were attributed to the instillation procedure rather than the nature of the instilled material. Breathing mechanics and arterial blood gases at rest were not affected in either Groups 1 or 2. However, the maximal expiratory peak flow recorded during lobeline-induced hyperventilation was significantly lower (P<0.05) and the total pulmonary resistance significantly higher (P<0.05) on Day 1 in Group 1, but not Group 2. These observations suggest that expiratory flows might be partly limited in bleeders when breathing at high airflow [less ▲]
