Sirtuins – universal regulators of cell function

Sirtuins as regulators of mammalian aging

the discovery that overexpression of yeast Sir2 deacetylase extends lifespan by as much as 30% over a decade ago [1], much effort has been invested in researching whether this effect is conserved in higher organisms as well. Indeed, in wormsand flies, two separate groups found that SIR2 extended lifespan as well, by 50% and 18%, respectively [1]. In parallel to the work in worms and flies, rese...

Sirtuins as Regulators of the Yeast Metabolic Network

There is growing evidence that the metabolic network is an integral regulator of cellular physiology. Dynamic changes in metabolite concentrations, metabolic flux, or network topology act as reporters of biological or environmental signals, and are required for the cell to trigger an appropriate biological reaction. Changes in the metabolic network are recognized by specific sensory macromolecu...

‏‎interpersonal function of language in subtitling

‏‎translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...

Altered expression of cell cycle regulators in adult T-cell leukemia/lymphoma patients

Abstract Background: Adult T-cell leukemia/lymphoma (ATLL) is caused by human T-cell lymphotropic virus type-1 (HTLV-1).  HTLV-1 oncogenes can induce malignancy through controlled gene expression of cell cycle checkpoints in the host cell. HTLV-I genes play a pivotal role in overriding cell cycle checkpoints and deregulate cellular division. In this study, we aimed to determine and comp...
