The complete sequence of the 8.2 kb segment left of MAT on chromosome III reveals five ORFs, including a gene for a yeast ribokinase.

We report here the DNA sequence of a segment of chromosome III extending over 8.2 kb. The sequence was determined using the random clone strategy followed by oligonucleotide-directed sequencing. The segment contains five long open reading frames, YCR521, 522, 523, 524 and 526, with only short distances between them. YCR523 (333 codons) encodes a ribokinase, a new function for yeast. YCR526 originates inside the MAT cassette, which is in continuity with the present segment, and extends over 358 codons outside of MAT. YCR524 (923 codons) codes for a putative membrane protein. YCR521, 522 and 524, have each been disrupted by insertion of a URA3 cassette and are non-essential genes. An active ARS element is located within YCR523 or its vicinity.

Preemptive renal transplantation in adults.

Recent studies have clearly demonstrated that preemptive renal transplantation is associated with better graft and patient survival. It improves the quality of life and is a cost-effective option compared to conventional transplantation. We report our experience with this concept and review the literature. We retrospectively analyzed all adult kidney transplantations performed in our center between March 1986 and May 2004: among 463 renal transplantations 44 were preemptive (9.5%). Mean follow-up was 45.7 +/- 6 months in preemptive versus 62.3 +/- 2.6 months in the other group. At the end of the study, graft survivals were 93.2% and 77.1%, respectively (P = .02). Patient survival rates were similar in both groups. In the preemptive group, grafts were more likely to come from living donors (P < .001) and cold ischemia time was shorter (P = .02). A subgroup case-control study showed that cost saving for dialysis in the preemptive group was about 119,000 Euros per patient. More preemptive patients had professional activity before (P = .0002) and after transplantation (P = .02). Our results and data from the literature support the place of preemptive transplantation as the optimal mode of renal replacement therapy for medical and socioeconomic reasons.

Trinucleotide repeats and other microsatellites in yeasts.

Microsatellites are direct tandem DNA repeats found in all genomes. A particular class of microsatellites, called trinucleotide repeats, is responsible for a number of neurological disorders in humans. We review here our current state of knowledge on trinucleotide repeat instability, and discuss the molecular mechanisms that may be involved in trinucleotide repeat expansions leading to fatal diseases in humans. We also present original data on microsatellite distribution in several microbial genomes, and on the use of microsatellites as physical markers to accurately and easily genotype yeast strains.

[Erythema multiforme induced by the combination of phenytoin and cerebral irradiation].

The authors report the case of erythema multiforme characterized by its cephalic onset and its rise after association phenytoin and cranial irradiation, for glioblastoma with epileptic fits. Eight similar cases are observed in literature with the same timing. Benign outcome is not always the rule because 2 patients died. This type of reaction being not forseeing, and outcome very varying, we suggest to avoid phenytoin in patients having a cerebral tumor revealed by epilepsy and needing a cranial irradiation.
