Transforming growth factor β1 (TGF-β1) has a large role in the control of autoimmunity. Single nucleotide polymorphisms (SNP) in the promoter of TGF-β1 cytokine gene are known to alter the production of this important cytokine. Decreased levels of

Reducing friction is an important target for any lubricant oil formulator. There are several ways, such as utilisation of multi-grade oils with low viscosity at low temperature, or use of friction modifiers, to reduce friction in automotive engines a
