[Validation of the Montreal Cognitive Assessment (MoCA) as a screening tool for mild cognitive impairment in the population of Buenos Aires, Argentina].

Introduction: The Montreal Cognitive Assessment (MoCA) test is a brief tool for neuropsychological assessment.

Objective: to validate the MoCAin the population of Buenos Aires, Argentina, to allow for the use of the test for the detection of Mild Cognitive Impairment (MCI).

Methods: The sample consisted of 269 adults over 60 years old and of schooling of more than 6 years (healthy adults n = 115 and MCIn = 154).

Nanoparticle corona for proteins: mechanisms of interaction between dendrimers and proteins.

Protein absorption at the surface of big nanoparticles and formation of 'protein corona' can completely change their biological properties. In contrast, we have studied the binding of small nanoparticles - dendrimers - to proteins and the formation of their 'nanoparticle corona'. Three different types of interactions were observed.

[Effect of intravenous laser irradiation on some blood biochemical indicators in the acute stage of lacunar infarcts].

Objective: To investigate the dynamics of lipid metabolism, C-reactive protein (CRP), lipid peroxidation and antioxidant system in lacunar infarction (LI) in chronic cerebral ischemia.

Material And Methods: Two groups of patients were studied. The main group included 31 patients who received intravenous laser irradiation of blood (ILIB) with semiconductor laser (wavelength - 0.
