Involvement of Escherichia coli YbeX/CorC in ribosomal metabolism.

YbeX of Escherichia coli, a member of the CorC protein family, is encoded in the same operon with ribosome-associated proteins YbeY and YbeZ. Here, we report the involvement of YbeX in ribosomal metabolism. The ΔybeX cells accumulate distinct 16S rRNA degradation intermediates in the 30S particles and the 70S ribosomes.

Deposition of Magnetite Nanofilms by Pulsed Injection MOCVD in a Magnetic Field.

This report is on the growth of Fe₃O₄ nanofilms on Al₂O₃(0001) and MgO(001) substrates with and without the presence of an external magnetic field using a pulsed injection metallorganic chemical vapour deposition (PI MOCVD) technique. The effects of growing magnetic oxide nanofilms in a 1 T field have been examined using various instrumental methods. It was found that the application of a magnetic field during PI MOCVD does not drastically alter the crystalline texture, surface morphology, and film thickness, but it significantly modifies the Fe₃O₄ film magnetisation and coercive field.

Lack of association of G-protein subunit gene C825T polymorphism with left ventricular hypertrophy in essential hypertension.

Background: The aim of the present study was to determine if there is an association of G-protein b3 subunit (GNB3) gene polymorphisms and left ventricular hypertrophy (LVH) in patients with essential hypertension (EH) in a St. Petersburg population.

Material/methods: We examined 135 patients (mean age 48 +/- 7 yrs) with mild to moderate EH recruited from the general population of an outpatient hypertension clinic.

Lack of association of the renin-angiotensin system genes polymorphisms and left ventricular hypertrophy in hypertension.

Objective: The aim of the present study was to determine if there is an association of different gene polymorphisms of renin-angiotensin system and left ventricular hypertrophy (LVH) in patients with essential hypertension (EH) in St Petersburg population.

Patients And Methods: We examined 156 patients (the mean age 49+/-8 years) with mild-to-moderate EH recruited from the general population of the outpatient clinic. Left ventricular mass was measured by echocardiography and left ventricular mass index (LVMI) was calculated.
