Effect of length of productive life on genetic trend of milk production and profitability: A simulation study

Longevity is an important economic trait in dairy cattle. Including this trait in a breeding scheme, increases profit. The aim of this study was to evaluate the relationship between length of productive life (LPL), genetic trend of milk production and profitability of herds. LPL has been defined as time from first calving to culling.A Dynamic stochastic model was used to simulate dairy herd system. This model consisted of biological characteristics such as reproduction, genetic and economic components. Both discrete (time-oriented) events such as freshening and breeding as well as continuous processes such as milk production and feed consumption were simulated individually for each animal. The basiccharacteristics of the animal component included pedigree, genetics, age at calving, number of service per conception, number of lactations and LPL. Other characteristics included time-oriented characteristics such as weight, age, physiological status, lactation stage, open days, pregnancy days,estrus cycle, service date and feed requirements. The herd was described as several animal groups: young stock (<1 year old), heifers (>1 year old) and several groups of lactating and dry cows. Increasing mean LPL of herd from 35 to 65 months over 20 years resulted in decreased herd genetic merit of milk from 2025 to 1751 kg and mean of herd genetic trend per year was decreased from 101.24 to 87.56 kg, because of increased generation interval. Increasing LPL resulted in increased profit. Increasing LPL was associated with decreased costs for raising replacement heifers and sale of surplus heifers increased. The ratio of cumulative discounted profit (CDP) for herds with 40, 45, 50, 55, 60 and 65 months of LPL to the lowest level of LPL (35 month), were 1.22, 1.43, 1.55, 1.68, 1.79 and 1.90respectively across time

The impact of information quantity and strength of relationship between training set and validation set on accuracy of genomic estimated breeding values

Recent advances in genomic selection are a revolution in animal breeding. A genome consisting 10 chromosomes each with 100 cM in length with 100 equally spaced markers (1 cM) were simulated. After 50 generations of random mating in a finite population (Ne = 100) in order to create sufficient linkage disequilibrium, population was expanded to two different population sizes of 500 and 1000. This structure was conserved until generation 59. Only females of generations 51 to 58 had phenotypicrecords and were included in the training set. The generation 59 was assumed as juveniles without any phenotypic records (validation set). Two measures of heritability (h2 = 0.1 and h2 = 0.5) were considered.Each simulation was replicated 10 times and results were averaged across replications. The results showed that using individuals of more recent generations in training set led to higher accuracy of genomic estimated breeding values (GEBVs) than individuals from more distant generations. However, increase in the amount of phenotypic records in training set even from individuals of older generations will increase accuracy of GEBVs. Number of phenotypic records in training set was shown to haveimportant role in accuracy of GEBVs especially for low heritability traits

Threshold Voltage Compensation Error in Voltage Programmed AMOLED Displays

© 2005-2012 IEEE. A new accurate voltage-programmed pixel circuit for active-matrix organic light-emitting diode (AMOLED) displays is presented. Composed of three TFTs and one storage capacitor, the proposed pixel circuit is implemented both in a-Si and a-IGZO TFT technologies for the same pixel size for fair comparison. The simulation result for the a-Si-based design shows that, during a programming time of {\hbox{90}}μ \hbox{s} , the pixel circuit was able to compensate for a 3 V threshold voltage (V\rm th) shift of the drive TFT with almost no error. In contrast, the a-IGZO-based pixel circuit, has a larger current error (of around 8%), despite its proven three-fold higher speed.Authors thank to the EPSRC under Project EP/M013650/1

Experimental Modeling of Cyclists Fatigue and Recovery Dynamics Enabling Optimal Pacing in a Time Trial

Improving a cyclist performance during a time-trial effort has been a challenge for sport scientists for several decades. There has been a lot of work on understanding the physiological concepts behind it. The concepts of Critical Power (CP) and Anaerobic Work Capacity (AWC) have been discussed often in recent cycling performance related articles. CP is a power that can be maintained by a cyclist for a long time; meaning pedaling at or below this limit, theoretically, can be continued for infinite amount of time. However, there is a limited source of energy for generating power above CP. This limited energy source is AWC. After burning energy from this tank, a cyclist can recover some by pedaling below CP. In this paper we utilize the concepts of CP and AWC to mathematically model muscle fatigue and recovery of a cyclist. Then, the models are used to formulate an optimal control problem for a time trial effort on a 10.3 km course located in Greenville SC. The course is simulated in a laboratory environment using a CompuTrainer. At the end, the optimal simulation results are compared to the performance of one subject on CompuTrainer.Comment: 6 pages, 8 figure

Glutathione, cell proliferation and differentiation

All organisms require an equivalent source for living. Reduced glutathione is the most abundant thiol containing protein in mammalian cells and organs. Glutathione was discovered by Hopkins in 1924 who published his findings in JBC. It is a three peptide containing glutamic acid, cystein and glycin and is found in reduced and oxide forms in cell. High concentration of glutathione and its high reduced/oxide potential makes GSH a powerful antioxidant and the first defense line against free radicals. However, glutathione is the most efficient tool for detoxification of xenobiotic. In several studies, the effect of GSH on different cell types has been investigated and so, in this study, a review of the glutathione function, focusing on cell proliferation and differentiation would be carried out.Key words: Glutathione, proliferation, differentiatio

Closure of complicated palatal fistula with facial artery musculomucosal flap

Background: Palatal fistulas occur most commonly as a complication of cleft palate surgery. Treatment of these fistulas, especially when they are wide and scarred, is a challenge for both patients and plastic surgeons, with a high rate of recurrence. Methods: The authors have operated on 22 cases of wide, scarred, recurrent palatal fistula with the use of the facial artery musculomucosal flap, first introduced by Pribaz et al. in 1992. The patients were operated on from March of 2001 to December of 2002 and ranged in age from 2 to 21 years. This flap is axial, centered over the facial artery, and can be raised inferiorly based or superiorly based. All of these patients with cleft palate had been operated on before. In one case, because of a very wide fistula, a bilateral facial artery musculomucosal flap was used. Results: There were two cases of partial necrosis and one case of complete failure, probably caused by twisting of the whole pedicle. The nasal lining was made using turndown flaps of the fistula margin. Because of hanging the base of the flap (inferiorly based) and producing bite block during mastication, the pedicle had to be divided and the flap inset secondarily 1 month later. Conclusions: The facial artery musculomucosal flap is an alternative for closing the scarred, wide, recurrent fistula, and is associated with a high rate of success. The flap should be included among the techniques of any plastic surgeon who performs palatal surgery
