Reversible Self-Assembled Monolayers (rSAMs) as Robust and Fluidic Lipid Bilayer Mimics.

Lipid bilayers, forming the outer barrier of cells, display a wide array of proteins and carbohydrates for modulating interfacial biological interactions. Formed by the spontaneous self-assembly of lipid molecules, these bilayers feature liquid crystalline order, while retaining a high degree of lateral mobility. Studies of these dynamic phenomena have been hampered by the fragility and instability of corresponding biomimetic cell membrane models.

Mutations in the rpoB gene of rifampicin-resistant Mycobacterium tuberculosis clinical isolates from Lithuania.

A total of 196 rifampicin (RMP) resistant Mycobacterium tuberculosis isolates were searched for mutations in the cluster I region of the rpoB gene. Seventeen different types of mutations were observed in 184 (93.9%) isolates.

High prevalence of drug-resistant tuberculosis, Republic of Lithuania, 2002.

Background: Nations of the former Soviet Union have the world's highest reported levels of resistance to anti-tuberculosis drugs. We conducted the first national survey of anti-tuberculosis drug resistance in the Republic of Lithuania.

Methods: We tested Mycobacterium tuberculosis isolates from all incident culture-positive pulmonary TB patients registered in 2002.

Molecular characterization of isoniazid-resistant Mycobacterium tuberculosis clinical isolates in Lithuania.

Mutations at codon 315 of the katG gene were detected in 312 of 364 (85.7%) isoniazid-resistant Mycobacterium tuberculosis isolates. Seven of 52 (13.
