C major variations

Equivalent Keys in HFE, C*, and Variations

In this article, we investigate the question of equivalent keys for two Multivariate Quadratic public key schemes HFE and C∗−− and improve over a previously known result, to appear at PKC 2005. Moreover, we show a new non-trivial extension of these results to the classes HFE, HFEv, HFEv-, and C∗−−, which are cryptographically stronger variants of the original HFE and C∗ / MIA schemes. In partic...

Variations in vitamin C levels in leukemias

Vitamin C is a six-carbon lactone that is synthesized from glucose in the liver of most mammalian species, but not by humans. Vitamin C is an electron donor and therefore a reducing agent. All known physiological and biochemical actions of vitamin C are due to its action as an electron donor and therefore it is good free radical scavenger. In humans, vitamin C acts as an electron donor for eigh...

Epigenetics: a major cause of variations on the same theme

The Human Genome project is gradually finalizing the last details of the Human DNA sequence. It is only a matter of time before all 23,000 genes and their gene products will have been mapped and characterized. The results of this historic achievement have brought some interesting findings to light. The polymorphic sequence variants (SNP) and copy variants (PCV) in the genome have opened new ave...

Genetic variations among three major ethnic groups in Nigeria using RAPD

Genetically, every individual is unique; this may stem from inheritance, geographical locations, and/or environmental interactions. This study examined the possibility of developing a cheap and easy-to-use marker that can distinguish among the three ethnic groups in Nigeria using RAPD-PCR. Five RAPD primers, OPA1-3 and OPC1-2, were randomly selected and used to amplify DNA samples isolated from...
