Longevity pathways converge on autophagy genes to regulate life span in Caenorhabditis elegans Autophagy‚ translated from Greek means to ‘self eat’. It is a basic catabolic mechanism involving cell degradation of unwanted or dysfunctional cellular components through the lysosome. Autophagy has been speculated to alter lifespan in organisms. Autophagy is triggered in response to varied stress and physiological conditions like food deficit‚ hyperthermia‚ etc. At molecular level‚ an autophagy pathway

Gladstone’s liberalism undoubtedly played a huge role in deiciding the structure of domestic legislation of his first ministry‚ However it is believed that pressure and practicality are possible factors as well. Gladstone led a political party that was itself the product of the changing social and economic conditions taking place in Britain during the 19th century. It is important that we understand Gladstone’s involvement in poltics was very much directly related to his religious beliefs. Much

Examining the RNA Interference Mechanism in the dpy-13 Gene in C. Elegans Through Feeding Mehdi Misto Lab: Monday 1:00 – 4:50 PM 11 December 2012 Introduction: RNA interference‚ or RNAi‚ is a biological process in which RNA molecules reduce the gene expression of an organism. This is done typically by causing the destruction of specific mRNA molecules. RNAs are direct products of genes‚ these small RNAs can bind to other mRNA molecules to either increase or decrease their activity like in the example

Introduction Globalisation‚ defined as the process of increasing integration and interdependence between countries and societies through the movement of people‚ goods‚ service‚ information and communication‚ such that events occurred in a part of the world will affect the others (Baylis‚ Smith & Owens 2008; Fischer 2003; Hill‚ Wee & Udayasankar 2012; Robins 2000) and is linked with the theory of modernisation (Modelski 1972 and Morse 1976).

Although genes play a significant part to a successful life in this world‚ the path and success of one’s life is not determined solely on DNA as demonstrated by Eugene‚ Anton and in particular‚ Vincent who clearly "exceeds his potential".

positions taken when decoding an image are said to be dominant‚ negotiated and oppositional. Choose two images‚ one from the genre of documentary and one from advertising‚ and explain the process of encoding and decoding to explain these three positions the viewer may take when decoding your chosen images. Stuart Hall’s text‚ “Encoding‚ Decoding” identifies three positions one can take in decoding an image. These three positions are dominant‚ negotiated and oppositional. In light of Hall’s theory

"The defendant who seeks to avoid criminal liability on the basis that s/he was suffering from a mental disorder at the time of the alleged crime must have a defence that falls within one of the following‚ legally recognised‚ categories: Insanity‚ Diminished Responsibility or Automatism. While‚ at one level or another‚ these "mental disorder defences" share common characteristics‚ they each differ significantly. Unfortunately‚ this point does not appear to be fully appreciated in English Law." Discuss

1. Introduction Since the discovery of plasmid‚ various methods have been developed to isolate plasmid DNA. All the methods have one common and important target of isolating plasmid DNA of high quality and quantity in less time. These methods are not completely safe because of use of toxic chemicals compounds. The developed protocol for plasmid extraction is based on the alkaline lysis method of plasmid preparation (extraction at pH 8.0) with slight modifications. Cell lysis reagent sodium dodecyl
