Robust and accurate cancer diagnosis and classification is very important in cancer treatment. A microarray data produce a large amount of data that are irrelevant, noisy and highly dimensional. Most of the genes are uninformative which degrades the performance of data mining and machine learning tasks. To reduce the curse of dimensionality, a preprocessing step known as feature selection is done. Feature selection is referred as selecting only a fraction of features that are most predictive of a given outcome. To deal with these issues, classification tools should robustly learn to identify a subset of informative genes embedded in large data set that has high dimensional noises. In this paper, an integrated approach of FNT (Flexible Neural Tree) and swarm optimization is proposed to simultaneously optimize the selection of feature subset and the classifier. A hierarchical neural network like structure is flexible neural tree (FNT).which is automatically created and optimized using evolutionary like algorithms to solve a given problem. Because of the most distinctive feature of flexible neural tree structure, it is not necessary to set the structure and weights of neural networks prior the problem is solved. The architecture of FNT is created with Ant Colony Optimization (ACO) and the parameters of the neural tree are optimized by Particle Swarm Optimization (PSO) algorithm and its enhancement (EPSO). The experimental results indicate that the proposed technique is feasible and efficient for the classification of microarray data. Copyright © 2012 ACM.

An overview of the weaving industry, one of the important sector for Indian textile industry, is presented. During April-December 2008, the cotton textiles including handlooms exports have amounted to $3,765 billion, recording a decline of 11.39 per cent over the exports during the corresponding period of 2007. Indian weaving industry has conventionally been one of the most promising sectors of huge employment. In fact, after agriculture, this industry is the largest provider of work force. Though weaving is one of the important sector for Indian textile industry, it has not been given due attention like spinning sector. Moreover structure of the industry plays, a major rote in making it competitive. Nature of this sector is mainly unorganized. Over 38,00,000 weaving industries have been built throughout the country, and more than 15,00,000 domestic weaving industries have been set up in the North and Eastern parts of the country.

Pretreatment of knitted fabrics is essential as it forms the base or all further processing. New alternatives have replaced conventional alkaline scouring and bleaching performed at high temperatures, which cause pollution to environment. This paper discusses the effect of bio pretreatment on lycra cotton weft knits in comparison with chemical pretreatment. It was observed that enzymatic pretreatment resulted in improved properties essential for further processing.

Cancer is one of the leading causes of death in humans. It is believed that plants can provide potential bioactive compounds for the development of "new leads" to combat cancer and other diseases. The present study focuses on the ability of the different extracts (aqueous, methanol, and chloroform) of the leaves of Zea mays in influencing the process of apoptosis induced by hydrogen peroxide (H2O2) in Hep2 (laryngeal carcinoma) cells. Various apoptosis-related parameters, such as cell viability, morphological changes, nuclear changes, and apoptotic index were characterized. sulforhodamine B and MTT assays were used to quantify the extent of cell death in the group exposed to H2O2, plant extracts, and their combination. Treatment with H2O2 caused cytotoxicity in cancer cells. The administration of leaf extract also caused an increase in the death of cancer cells. Oxidatively stressed cancer cells co-treated with all the Z. mays leaf extracts (except the chloroform extract) demonstrated cytotoxicity on a par with the H2O2-treated groups. This indicated that the aqueous and methanol leaf extracts did not influence the cytotoxic action of H2O2 in the cancer cells. Thus, various apoptosis-related events in Hep2 cells exposed to leaf extract throw light on the potential anticancer activity of the Z. mays leaves. The maximum activity was exerted by the methanolic extract followed by the aqueous and chloroform extracts. © 2013, International Pharmacopuncture Institute.

Man-Made Textiles in India | Year: 2011
Today, eco-friendly Multifunctional finishing of textile has been provided with the consumers increasingly awareness towards the health and hygiene. Consumers worldwide are looking for clothing, which provides greater comfort and remains fresh and odor-free in use. In this paper, an attempt has been made to discuss the importance of herbal finishes to the Denim fabric using Methanolic extracts of Jatropha leaves and Seena Auriculata and Aqueous extract of Euphorbia Hirta by exhaustion method to enhance the multifunctional property. This work will throw more light on the value addition and marketability of the Denim related products.
