High magnesium or potassium hair accumulation is not associated with ischemic stroke risk reduction: a pilot study.

Objectives: Various studies suggest that deficiency of magnesium and potassium may be associated with increased risk of ischemic stroke. However, single time-point serum measurements may not be suitable for assessing long-term tissue levels.

Patients And Methods: We investigated Mg and K levels in hair of patients with acute ischemic stroke.

Molecular and clinical consequences of in vivo silicones biodegradation.

The object of the publication is the presentation of data referring to in vivo silicones biodegradation and their potential clinical and molecular consequences. Summing up, one needs to state that the products of silicones biodegradation are not biologically indifferent. In particular, different types of silanols are inhibitors of proteolytic enzymes and regulators of many metabolic processes as well as affect the cell growth and division, which distinctly indicates the potentially strong pharmacological action.
