624 The reduced Enigma

The reduced

This article describes a simplified cryptographic machine, based closely on the World War II Enigma. This ‘reduced Enigma’ exposes some of the design flaws of the original Enigma in a new way. Had the Axis powers built a reduced Enigma, the outcome of the war might have been different. A fully working reduced Enigma has been used very successfully in numerous public lectures, in school talks, a...

The Enigma of Human T-Cell Leukemia Virus Type-1 (HTLV-1) Infection in Iran

Human T-cell lymphotropic virus type-I (HTLV-I) was the first human retrovirus associated with malignancy.  The prevalence of HTLV-I infection varies significantly in different regions of the world.  In this study, the prevalence of HTLV-I infection among ethnic Jews living in Shiraz, South of Iran, was investigated. 286 blood samples were obtained.  HTLV-1 antibody assay on serum samples was d...

The role of Junk DNA

Many efforts have been done in order to explain the role of junk DNA, but its function remain to be elucidated. In addition the GC-content variations among species still represent an enigma. Both these two mysteries can have a common explanation: we hypothesize that the role of junk DNA is to preserve the mutations probability that is intrinsically reduced in GC-poorest genomes.

Metabolism of bisphenol A by hyper lignin-degrading fungus Phanerochaete sordida YK-624 under non-ligninolytic condition.

Recently, we reported the conversion of bisphenol A (BPA) to 4-(2-(4-hydroxyphenyl)propan-2-yl)benzene-1,2-diol (hydroxy-BPA) by hyper lignin-degrading fungus Phanerochaete sordida YK-624 under non-ligninolytic condition. In the present study, the metabolism of hydroxy-BPA by P. sordida YK-624 was demonstrated under non-ligninolytic condition. Under these conditions, approximately 66% of hydrox...
