Heptamethyl cobyrinate was transformed into hexamethyl 8-nor-cobyrinate. The crucial step involved the synthesis of new, vitamin B12 derived cobryketone via palladium-catalyzed cleavage of the sp(3)-sp(3) carbon-carbon bond with the liberation of the ketone. The replacement of sp(3) carbon atom with

Although a higher consumption of alcohol, which is a methyl-group antagonist, was previously associated with colorectal cancer risk, mechanisms remain poorly understood. We hypothesized that excess alcohol consumption might increase risk of colorectal carcinoma with hypomethylation of insulin-like growth factor

Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disease characterised by paroxysmal attacks of serosal inflammation. Colchicine is highly effective in preventing these attacks but it may also disrupt the intestinal absorption of vitamin B12. We hypothesised that patients

Reports from some Western countries indicate that mandatory folate food fortification (FFF) has substantially reduced the prevalence of folate deficiency, leading to calls for folate testing following FFF to be limited to specific indications such as macrocytic anaemia. This is
