Hyperhomocysteinemia in patients with cognitive impairment

Cognitive impairment is common in elderly people and represents clinical feature of neurodegenerative diseases. Not all of patients with Mild Cognitive Impairment (MCI) finally develop dementia and it is interesting to investigate the role of possible markers for early diagnosis. Hyperhomocysteinemia is associated to several pathologies including cognitive impairment; aim of this study is to evaluate the correlation between cognitive performance assessment and homocysteine plasma levels. Total 74 patients and 75 healthy controls were enrolled and MCI were defined by a MMSE score lower than 26 after adjustment for years of schooling. Homocysteine plasma levels were determined. Homocysteine levels significantly raised in patients with cognitive impairment and showed a significant negative association with MMSE score. Finally, our data show that a moderate risk of cognitive impairment could be associated to high homocysteine plasma levels

Erratum: By promoting cell differentiation, miR-100 sensitizes basal-like breast cancer stem cells to hormonal therapy

This article has been corrected: Due to errors in image assembly, the flow cytometry profiles depicting the isotype matched control (IMC) for CD49f on both scramble (scr) and miR-100 reported in Figure 6 are incorrect. Additionally, we noticed that the IMC reported for CD24 and CD10 in miR-100 are the same. Being both CD24 allophycocianin (APC) and CD10 APC IgG1, they should have the same IMC, as already reported. The corrected Figure 6 is shown below. The authors declare that these corrections do not change the results or conclusions of this paper
