Tropical infection after a case of total hip arthroplasty.

In non-endemic areas, malaria is mainly an imported disease. This article reports a case of transfusion-related Plasmodium falciparum malaria in a non-endemic area. Despite initial clinical signs consistent with malaria, the diagnosis was not elicited because of the absence of any identified epidemiological risk factors.

Epilepsy caused by an abnormal alternative splicing with dosage effect of the SV2A gene in a chicken model.

Photosensitive reflex epilepsy is caused by the combination of an individual's enhanced sensitivity with relevant light stimuli, such as stroboscopic lights or video games. This is the most common reflex epilepsy in humans; it is characterized by the photoparoxysmal response, which is an abnormal electroencephalographic reaction, and seizures triggered by intermittent light stimulation. Here, by using genetic mapping, sequencing and functional analyses, we report that a mutation in the acceptor site of the second intron of SV2A (the gene encoding synaptic vesicle glycoprotein 2A) is causing photosensitive reflex epilepsy in a unique vertebrate model, the Fepi chicken strain, a spontaneous model where the neurological disorder is inherited as an autosomal recessive mutation.

Addition of the microchromosome GGA25 to the chicken genome sequence assembly through radiation hybrid and genetic mapping.

Background: The publication of the first draft chicken sequence assembly became available in 2004 and was updated in 2006. However, this does not constitute a definitive and complete sequence of the chicken genome, since the microchromosomes are notably under-represented. In an effort to develop maps for the microchromosomes absent from the chicken genome assembly, we developed radiation hybrid (RH) and genetic maps with markers isolated from sequence currently assigned to "chromosome Unknown" (chrUn).

The chicken RH map: current state of progress and microchromosome mapping.

The ChickRH6 radiation hybrid panel has been used to construct consensus chromosome radiation hybrid (RH) maps of the chicken genome. Markers genotyped were either from throughout the genome or targeted to specific chromosomes and a large proportion (one third) of data was the result of collaborative efforts. Altogether, 2,531 markers were genotyped, allowing the construction of RH reference maps for 20 chromosomes and linkage groups for four other chromosomes.
