[Diagnostics of pneumothorax with ultrasound].

The article deals with a method of pneumothorax diagnostics based on verification of four ultrasound sings--lung sliding absence, B-lines absence, lung pulse absence and lung point presence. Use of ultrasound allows to quickly diagnose a pneumothorax and to monitor the condition of pleural space. Introduction of the ultrasound methods into routine work ICU specialists can increase safety of patients.

[Molecular basis of Parkinson's disease linked with mutations in the LRRK2 gene].

Parkinson's disease (PD) is a common neurodegenerative disorder. Disease symptoms correlate with the degeneration of dopaminergic neurons in substantia nigra pars compacta. A number of factors are supposed to take part in PD pathogenesis including alpha-synuclein aggregation, oxidative stress, mitochondrial dysfunction and apoptosis, although the precise molecular mechanism of neudegeneration remains unknown.

[Apoptosis of peripheral blood lymphocytes in patients with LRRK2-assoctated Parkinson's disease].

Mutations in the Leucine Reach Repeat Kinase 2 (LRRK2) gene are the most frequent cause of familial Parkinson's disease (PD). Although the precise physiological and pathological role of LRRK2 is unclear, a direct link between mutant LRRK2 and apoptosis has been suggested. Using flow cytometric analysis (PI+Annexin V(FITC)) we showed increased spontaneous apoptosis of peripheral blood lymphocytes in patients with LRRK.

[Molecular genetics and clinical aspects of monogenic diabetes mellitus].

The paper is dedicated to clinical and laboratory aspects of Diabetes Mellitus non-immune forms, such as neonatal Diabetes Mellitus, Maturity Onset Diabetes of young (MODY), DIDMOAD-syndrome, Wolframe syndrome, Alstrom syndrome and its determinating genes. The analysis of proper clinical results are present in this paper.

[Clinical features of LRRK2-associated Parkinson's disease].

Mutations in the Leucine Reach Repeat Kinase 2 (LRRK2) gene are the most frequent cause of familial Parkinson's disease (PD). Previously, we have sequenced the coding region of the LRRK2 gene in 85 PD patients and showed the prevalence of G2019S-associated PD (G2019S-PD) among all cases of LRRK2-associated PD in Russia. Screening of the most frequent LRRK2 mutations (G2019S, R1441C, R1441G) in the extended sample of PD patients (100 familial cases, 14 relatives and 230 sporadic cases) revealed two novel families with G2019S-PD in the addition to LRRK2-associated PD cases identified earlier.
