Бренд:

Microarray is a novel technology to identify gene expression of thousands of genes simultaneously. This work is attempted to perform microarray data analyses to determine differential gene expression using the open-source R programming environment in conjunction with the open-source Bioconductor software.We describe procedures for analysis of data using box plots and recommended procedures from Affymetrix for quality control are discussed. The Robust Multichip Averaging (RMA) and MAS5 procedure was used for background correction, normalization and summarization of the AffyBatch probe-level data to obtain expression level data and to discover differentially expressed genes.. Heatmaps are used to demonstrate over and under expressed genes in conjunction with t-statistics for determining interesting genes while pFDR was performed to remove false negative. We showed, with real data, how implementation of functions in R and Bioconductor successfully identified differentially expressed genes that may play a role in obesity.

"Only a man who knows what it is like to be defeated can reach down to the bottom of his soul and come up with the extra ounce of power it takes to win when the match is even"- Muhammad Ali. Such were the words of the great boxing legend. In 1984, Ali was diagnosed with Parkinson's syndrome, a disease much more common in those subjected to severe head trauma, such as boxers. Ali began showing symptoms of the disease soon after retiring from the boxing ring in 1981. But his condition was not diagnosed until three years later. By that stage he had developed tremors, his speech was slurred, and his body movements had become slow. Doctors prescribed drugs which alleviated the worst of his symptoms.Despite the disability, he remains a beloved and active public figure. In 1985, he served as a guest referee at the inaugural WrestleMania event. Such determination can help anyone to combat the disease.

Microarray data analysis of M.tuberculosis whole genome using Genesis

Microarray data analysis of M.tuberculosis whole genome using Genesis drushti bhatt yogesh jasarai and himanshu pandya statistical approach to study microarray analysis using bioconductor
Бренд:

DNA microarrays are a powerful tool to investigate differential gene expression for thousands of genes simultaneously. Although DNA microarrays have been widely used to understand the critical events underlying growth, development, homeostasis, behavior and the onset of disease, the management of the resulting data has received little attention. Presently, the fluorescent dyes Cy3 and Cy5 are most often used to prepare labeled cDNA for microarray hybridizations. Raw microarray data are image files that have to be transformed into gene expression formats – a process that requires data manipulation due to systematic variations which may be attributed to differences in the physical and chemical dye characteristics. There are different approaches to analyse the large-scale gene expression data in which the essence is to identify gene clusters. This approach has allowed us to determine expression profiles of novel developmentally regulated genes. Finally we get some genes which highly coexpressed and may be involved in pathogenesis.

Analysis of cold stress using Affymetrix microarrays

Analysis of cold stress using Affymetrix microarrays drushti bhatt yogesh jasarai and himanshu pandya statistical approach to study microarray analysis using bioconductor
Бренд:

Recently, there have been emerging demands to analyse the function of genes from the gene expression profiles. DNA microarray is one of the most powerful tools, which enables the expression profiling of thousands of genes simultaneously. It has also proven to be an extremely valuable tool to efficiently utilize the enormous amount of information provided by the completion of numerous genome projects. Data clustering analysis has been widely applied to extract information and also to identify groups of genes or samples displaying a similar expression profile. In this experiment we have used the Affymetrix microarray Technology which is also known as GeneChip microarray. By using this Technology I have written this work on rice gene expression. In my book I have tried to find out which genes are regulated by cold stress, the genes that are affected by cold stress. The method is based on a generalized linear model. Several statistical tests have been done for the analysis and simulated datasets are used to show that the method performs substantially better than other common methods in the field. We have also used Hierarchical Clustering method to get the pattern of the unknown gene.

A Statistical Approach In Modelling Maize Prices Volatility

A Statistical Approach In Modelling Maize Prices Volatility drushti bhatt yogesh jasarai and himanshu pandya statistical approach to study microarray analysis using bioconductor
Бренд:

Volatility provides a measure of the possible variation or movement in the price of a commodity experienced over a given period of time . In this study, volatility of maize prices for Kenya, Uganda, and Tanzania in comparison with the FAO Global prices for the period of January 2003 to August 2011 is estimated. The study employs measures of dispersion like unconditional standard deviation and the coefficient of variation together with a 20% band around the trend line compared with time series models, the ARMA and EGARCH. Maize prices in Kenya, Tanzania, and FAO Global were found to be time varying and thus estimated using the EGARCH model and the average unconditional standard deviation used as a measure of volatility. Volatility of Uganda maize prices was constant over time and was estimated using ARMA (1,1). The study shows that by both methods, maize prices in Uganda were the most volatile followed by Kenya, Tanzania and then FAO Global implying that volatility in the East African markets is high compared to the global maize market.
