Periprosthetic knee infection by Mycobacterium bovis and Candida guilliermondii in the context of a zoonosis: a case report and review of the literature.

Introduction: Periprosthetic joint infections are a major challenge for treating physicians. Musculoskeletal infections with Mycobacterium bovis are extremely rare, with an assumed incidence of 0.08-0.

Minimal-invasive percutaneous reduction and transsacral screw fixation for U-shaped fractures.

Study Design: Technical note and case series.

Objective: To introduce an innovative minimal-invasive surgical procedure reducing surgery time and blood loss in management of U-shaped sacrum fractures.

Summary Of Background: Despite their seldom appearance, U-shaped fractures can cause severe neurological deficits and surgical management difficulties.

The DUF579 domain containing proteins IRX15 and IRX15-L affect xylan synthesis in Arabidopsis.

Xylan is the principal hemicellulose in the secondary cell walls of eudicots and in the primary and secondary cell walls of grasses and cereals. The biosynthesis of this important cell wall component has yet to be fully determined although a number of proteins have been shown to be required for xylan synthesis. To discover new genes involved in xylan biosynthesis we explored the psyllium (Plantago ovata Forsk) seed mucilaginous layer through EST profiling.

Porphyrins promote the association of GENOMES UNCOUPLED 4 and a Mg-chelatase subunit with chloroplast membranes.

In plants, chlorophylls and other tetrapyrroles are synthesized from a branched pathway that is located within chloroplasts. GUN4 (GENOMES UNCOUPLED 4) stimulates chlorophyll biosynthesis by activating Mg-chelatase, the enzyme that commits porphyrins to the chlorophyll branch. GUN4 stimulates Mg-chelatase by a mechanism that involves binding the ChlH subunit of Mg-chelatase, as well as a substrate (protoporphyrin IX) and product (Mg-protoporphyrin IX) of Mg-chelatase.

Monostotic fibrous dysplasia of the spine: report of a case involving a cervical vertebra.

Monostotic fibrous dysplasia of the spine is a rare entity. Only 26 cases, of which 11 were located in the cervical spine, are to be found in the literature. We report a 56-year-old male patient with cervicobrachialgia of half year's duration.
