Ceramic high-rate timing RPCs

Following some previous work, we report here considerable improvements on the counting rate capability of timing RPCs by the use of ceramic electrodes with a resistivity of 109 [Omega][dot operator]cm. The X-ray sensitivity of the detector depends linearly on the counting rate with a slope of 9% per 100 kHz/cm2, free from charge depletion effects, while keeping a timing accuracy, measured with 511 keV synchrono...

Clinical aspects of polycystic disease of the kidney in the adult.

Acute renal insufficiency as presentation form of multiple myeloma.

Multiple Myeloma (MM) causes a wide range of serious clinical, alterations, including acute renal failure (ARF) often present and contributing to the global mortality of this neoplasm. ARF usually occurs well after MM is diagnosed. We describe a case of ARF in a 42 years old male patient requiring urgent hemodialysis that subsequently proved to have MM. The singularity of this case lead us to review cases of AR...

Cytomegalovirus infection in kidney transplantation.

150 patients, subjected to kidney graft transplantation between January 1988 and December 1989, were studied. Mean +/- 95% CL age was 37.5 +/- 2.03 (range 12-69) years. IgG and IgM antibodies levels (ELISA) cytomegalovirus (CMV) were investigated in the donor before organ harvesting and in the kidney recipients on 1st and 21th days and then on the 3rd, 6th and 9th months after transplantation. Patients lacking ...

Kidney disease and pregnancy. Experience at the nephrology unit of Saint Mary's...

29 pregnancies in 27 renal patients were reviewed. The etiology of renal disease was mainly glomerular (14 patients). At the beginning of pregnancy 11 patients had renal failure and 14 patients had a high blood pressure. Only two patients had pregnancy related worsening of the renal function (the two patients had a normal renal function before pregnancy). Maternal morbidity was infrequent with no mortality. Fet...
