Age studies can furnish other basic data such as stock age structure, age at first maturity, spawning frequency, individual and stock responses to changes in the habitat, recruitment success, etc. Age and growth data also permit the determination of population changes due to fishing rates. Because a scale holds the growth history of the fish, it can also be used to determine length at all ages up to the current one. The present study results were showed that the fishes of ages 1, 1+, 2, 2+, 3, 3+, and 4, when the age level was increased, the length also increases but fish weight remains stable during ages 1+ and 2 and increase is seen only after age 3. The age of fish may be determined by various methods depending upon their suitability to the species concerned. In certain cases more than one method may be employed chiefly to verify the results obtained by the other.

EBFs have been characterised for their roles in differentiation of B-lymphocytes and neural cells.Recently,a new role for some EBFs in bone development has been investigated. However,their expression profile and regulation in the somites (axial skeleton precursor) have yet to be elucidated. I have found cEbf somitic expression in medial (cEbf1) and lateral (cEbf2 and cEbf3) sclerotomal domains and later around vertebral cartilage anlagen of body,pedicles (cEbf1) and arch (cEbf2 and cEbf3).I have presented a model in which expression cEbf1 is initiated by low dose of BMP4 from lateral mesoderm and maintained by Shh from notochord.However, the other two chick Ebf genes are induced by BMP4 and inhibited by high dose of Shh.I have also found that cEbf1 can induce other sclerotomal markers,Pax1 and Sox9,and dermomyotomal marker,MyoD,but antagonises lateral markers,cEbf3 and Pax3.Thus,cEbf1 is a sclerotomal marker expressed in axial skeletogenic tissues under control of Shh and Bmp4 and that this expression is crucial for sclerotome development and mediolateral patterning of somites. ····· 1036191989

Visual processing in the retina information is partly accomplished by laterally orientated horizontal cells. Two connexins, Cx52.6 and Cx55.5 has been shown to be expressed in zebrafish horizontal cells. Sequence analysis of zfCx55.5 and zfCx52.6 has revealed only limited homology of these connexins to other connexins from fish and higher vertebrates. ZfCx52.6 shows around ~57% amino-acid homology with zfCx55.5, where as the zfCx55.5 has been shown to share about 50% homology with the mouse Cx57. Both of these connexins have been found to show highly restricted expression in the horizontal cells of zebrafish retina. The molecular mechanism responsible for their cell specific expression are unveiled in this dissertation. Moreover, connexins perform various functions for which gap-junction communication seems to be dispensable.

The reason for disc degeneration involves a decrease in the concentration of living cells, a decline in the nutrient supply, accumulation of degraded extracellular matrix molecules, and exposure to heavy mechanical loading over a long period of time. Disc degeneration is significant healthcare problem that is in need of more reliable and cost-effective solutions. However, few effective treatment options are available at present, and treatment relies on disectomy, foraminotomy, laminectomy, or spinal segment fusions. The biological treatment of disc degeneration using tissue engineering techniques offers significant potential for minimizing the limitations of artificial discs and intensive surgery. Tissue engineering methods focus on repairing or regenerating the damaged tissue by culturing disc-specific cells with appropriate survival and growth and factors in a 3-D scaffolding that offers appropriate mechanical support. ····· 1036191902

The finding that similar genes are often regulated in a similar manner (co-regulated or `co-expressed`) has directed several `guilt-by-association` approaches in order to reverse-engineer the cellular transcriptional networks using gene expression data as a compass. This kind of studies has been considerably assisted in the recent years by the development of high-throughput transcript measurement platforms, specifically gene microarrays and next-generation sequencing. In this work, several approaches are described for improving the extraction and interpretation of the information contained in plant transcriptional data, obtained from microarrays or through next generation sequencing. Applications of these theoretical approaches, ranging from Pearson correlation to LASSO and hybrid methods, are described for the reverse engineering of tuber growth transcriptional networks, for the prediction of essential genes and in the task of defining the full transcriptome of the extremophile plant Thellungiella salsuginea. ····· 1036191572

The pathogenesis of HCV has not been fully explained, although steatosis is considered to contribute greatly to liver fibrosis progression, modulating host-cell lipid metabolism. Suspected underlying molecular mechanisms include interactions between HCV proteins and intracellular lipid metabolic pathways. Recent studies have suggested that the nucleocapsid of HCV (core) acts as a pathogenic factor involved in lipid droplet accumulation, changes in lipogenic gene expression and/or the activity of lipogenic proteins in a genotype-specific manner. In this book, we have tried to summarize the current knowledge regarding HCV-induced steatosis and the regulation of expression of host genes and receptors that aid in the viral life cycle and promote liver diseases. ····· 1036191478
