Optic nerve perineuritis and retroperitoneal panniculitis: rare first presentations of Behçet's disease.

A 46-year-old woman was admitted to our hospital because of high fever and lumbago. CT revealed increase in density of fat tissue around the aorta, suggesting retroperitoneal panniculitis. The following day, she reported of leg pain, pain in the mouth, painful urination and right eye pain that was exacerbated by eye movement.

Docosahexaenoic acid production and lipid-body formation in Schizochytrium limacinum SR21.

Schizochytrium limacinum SR21, a thraustochytrid (Labyrinturomycota), is a heterotrophic marine microorganism. SR21 has attracted recent attention because of the production of docosahexaenoic acid (DHA). We obtained highly concentrated SR21 zoospores and successfully observed synchronous growth.

Production of Fab fragment corresponding to surface protein antigen of Streptococcus mutans serotype c-derived peptide by Escherichia coli and cultured tobacco cells.

The cDNA of a mouse Fab fragment was cloned from a hybridoma cell line that produces a mouse monoclonal antibody, KH5, that reacts with the peptide fragment of the surface protein antigen of Streptococcus mutans serotype c (PAc). After transfection with cDNA, recombinant Fab fragments were produced by Escherichia coli (T15 Fab) and cultured tobacco cells (X253 and X262 Fabs). The antipeptide activities of T15 and X253 were similar to that of KH5.

Different frequencies of Streptococcus anginosus infection in oral cancer and esophageal cancer.

Multiple cancers frequently occur in the upper aerodigestive tract. The high incidence rate of multiple carcinomas in this region is often explained in terms of involvement of the same underlying risk factors. It has been reported that the oral bacterium Streptococcus anginosus (S.

Differences in pyrenoid morphology are correlated with differences in the rbcL genes of members of the Chloromonas lineage (volvocales, chlorophyceae).

Chloromonas is distinguished from Chlamydomonas primarily by the absence of pyrenoids, which are structures that are present in the chloroplasts of most algae and are composed primarily of the CO2-fixing enzyme Rubisco. In this study we compared sequences of the rbcL (Rubisco large subunit-encoding) genes of pyrenoid-less Chloromonas species with those of closely related pyrenoid-containing Chlamydomonas species in the "Chloromonas lineage" and with those of 45 other green algae. We found that the proteins encoded by the rbcL genes had a much higher level of amino acid substitution in members of the Chloromonas lineage than they did in other algae.
