Appropriate regulation of the Hog1 mitogen-activated protein kinase (MAPK) pathway is essential for cells to survive osmotic stress. Here, we show that the two sensing mechanisms upstream of Hog1 display different signaling properties. The Sho1 branch is an inducible nonbasal system, whereas the Sln1 branch shows high basal signaling that is restricted by a(More)
The arenavirus Lassa is found in West Africa, where it sometimes causes a severe illness called Lassa fever. Lassa fever has been seldom investigated outside of a few hyperendemic regions, where the described epidemiology may differ from that in areas of low or moderate incidence of disease. Through a prospective cohort study, we investigated the(More)
Alveolar soft-part sarcoma (ASPS) is a rare tumor. Cure is based solely on radical surgery. The general prognosis is poor. The tongue is an unusual site in adults, but not in children. Tumor removal can cause a severe impact on quality of life, even if reconstruction is possible. ASPS is a highly vascularized tumor and antiangiogenic therapy may have a(More)
Cells are subjected to dramatic changes of gene expression upon environmental changes. Stress causes a general down-regulation of gene expression together with the induction of a set of stress-responsive genes. The p38-related stress-activated protein kinase Hog1 is an important regulator of transcription upon osmostress in yeast. Genome-wide localization(More)
Diabetic nephropathy is the dominant cause of hypertension in insulin-dependent diabetics, and long-term rigid antihypertensive treatment inhibits the progression of nephropathy, probably even when there is renal insufficiency. In our clinical study 14 insulin-dependent diabetics with diabetic nephropathy and renal failure (glomerular filtration rate [GFR](More)
In 92 particularly unstable IDDM patients we have tried to avoid any gap in daily insulin supply by applying one out of four newly designed combinations of regular and depot insulin. The short-term effect after three weeks and the long-term effect after greater than or equal to 12 months (data from 30 patients only) of these new regimens were compared with(More)
The aetiopathogenesis of the diabetic nephropathy today is still unknown. Uncontested is the contribution of chronic hyperglycemia in the pathogenesis of diabetic nephropathy. For this, there are convincing evidences from clinical and experimental experiences including transplantation surgery. The quality of the metabolic adjustment of the diabetics from(More)
A transversal investigation carried out on 551 children and a longitudinal study of 55 infants showed the disappearance of maternal anti-plasmodium antibodies during the first year of life. Out of 212 new-borns surveyed for one year, 59 (28%) were infested by Plasmodium, but never during the first two months of life. This infestation was not related to the(More)
Among 216 women who had given birth in the rural health maternity centre of Maférinyah (Guinea), 32% had parasitemia with no clinical signs. Antimalarial antibodies could be measured only for 156 women and were present in all of them. Serological antimalarial tests were carried out on 133 newborns, all of whom had antibodies. The serological results of 122(More)
