Сочетание анкилозирующего спондилита и артериита Такаясу: описание клинического случая

The paper describes a rare clinical case of ankylosing spondylitis (AS) with concurrent with Takayasu arteritis (AT). It considers the common immunopathogenetic mechanisms that can link these two diseases. Taking into account that there may be common triggering factors for AS and AT, it is necessary to make an examination to diagnose AT when a patient with AS is found to have fever, an increase in the indicators of acute phase inflammation, and the objective signs of cardiovascular disease characteristic of large-vessel vasculitis.Представлено клиническое наблюдение редкого сочетания анкилозирующего спондилита (АС) с артериитом Такаясу (АТ). Рассмотрены общие иммунопатогенетические механизмы, которые могут связывать эти два заболевания. Учитывая возможное наличие единых провоцирующих факторов развития АС и АТ, при выявлении у пациента с АС лихорадки, повышения острофазовых показателей воспаления, объективных признаков поражения сердечно-сосудистой системы, характерных для васкулита крупных сосудов, необходимо проводить обследование с целью диагностики АТ

Polyphosphates as a source of enhanced P fluxes in marine sediments overlain by anoxic waters: Evidence from (31)P NMR

Sedimentary phosphorus (P) composition was investigated in Effingham Inlet, a fjord located on the west coast of Vancouver Island in Barkley Sound. Solid-state (31)P nuclear magnetic resonance (NMR) spectroscopy was applied to demineralized sediment samples from sites overlain by oxic and anoxic bottom waters. The two sites were similar in terms of key diagenetic parameters, including the mass accumulation rate, integrated sulfate reduction rate, and bulk sediment organic carbon content. In contrast, P benthic fluxes were much higher at the anoxic site. (31)P NMR results show that P esters and phosphonates are the major organic P species present at the surface and at depth in sediments at both sites. Polyphosphates were only found in the surface sediment of the site overlain by oxic waters. The varying stability of polyphosphates in microorganisms under different redox conditions may, in part, explain their distribution as well as differences in P flux between the two sites

Biosynthesis and secretion of bovine growth hormone in Escherichia coli under the control of the secretory vector containing a promoter and signal sequence of alkaline phosphatase gene

A recombinant plasmid was constructed containing the gene for bovine growth hormone joinea with the regulatory region and the region coding the signal sequence of the Escherichia coli alkaline phosphatase gene. In conditions of phosphorus starvation, which c~s derepression of alkaline phosphatase, expression was shown of the gene for bovine growth hormone, in addition to partial processing and secretion of protein into periplasm
