Classification has been used extensively in several problems domains. Automated gender classification is an area of great significance and has great potential for future research. It offers several industrial applications in near future such as monitoring, surveillance, commercial profiling and human computer interaction. Different methods have been proposed for gender classification like gait, iris and hand shape. However, majority of techniques for gender classification are based on facial information. In this paper, a comparative study of gender classification using different techniques is presented. The major emphasis of this work is on the critical evaluation of different techniques used for gender classification. The comparative evaluation has highlighted major strengths and limitations of existing gender classification techniques. Taking an overview of these major problems, our research is focused on summarizing the literature by highlighting its strengths and limitations. This study also presents several areas of future research in the domain of gender classification.

Using pharmacological and molecular approaches to manipulate intracellular O2*-, here we report that an increase in intracellular O2*- anion induces Na+/H+ exchanger 1 (NHE-1) gene promoter activity resulting in increased NHE-1 protein expression, which strongly correlates with the resistance of cells to death stimuli. In contrast, exposure to exogenous hydrogen peroxide suppressed NHE-1 promoter activity and gene expression, and increased cell sensitivity to death triggers. Furthermore, the increase in cell sensitivity to death upon downregulation of NHE-1 gene expression correlates with reduced capacity of cells to recover from an acid load, while survival upon overexpression of NHE-1 appears independent of its pump activity. These findings indicate that NHE-1 is a redox-regulated gene, and provide a novel intracellular target for the redox control o...
