“The clinical course and risk factors for developing end-stage renal disease (ESRD) after heminephrectomy in
living kidney donors have scarcely been investigated. We reviewed medical records and identified eight case donors who developed chronic kidney disease (CKD) stage 5 or ESRD, and subsequently investigated the association between postoperative clinical courses and changes in renal function. Cyclopamine order To conduct a case-control study, we also selected a control group comprising 24 donors who had maintained stable renal function and were matched for age, sex and follow-up time since donation. Except for one donor who developed ESRD caused by a traffic accident, none of the donors developed progressive renal dysfunction immediately after donation. Their renal functions remained stable for a long period of time, but started to decline after developing new comorbidities, especially risk factors known as progression factors (proteinuria or hypertension) or accelerating factors (cardiovascular [CV] event or infection) of CKD. As compared with the control donors, incidence of postoperative persistent proteinuria, acute CV event, severe infection and hospitalization due to accelerating factors of CKD were significantly higher in the case donors. These results suggest the importance of long-term (more than 10 years)
follow-up of donors with special attention on the risk factors of CKD.”
“Microsized aluminum/epoxy resin composites were prepared, and the thermal click here and dielectric
properties of the composites were investigated in terms of composition, aluminum particle sizes, frequency, selleck chemical and temperature. The results showed that the introduction of aluminum particles to the composites hardly influenced the thermal stability behavior, and decreased T of the epoxy resin; moreover, the size, concentration, and surface modification of aluminum particles had an effect on their thermal conductivity and dielectric properties. The dielectric permittivity increased smoothly with a rise of aluminum particle content, as well as with a decrease in frequency at high loading with aluminum particles. While the dissipation factor value increased slightly with an increase in frequency, it still remained at a low level. The dielectric permittivity and loss increased with temperature, owing to the segmental mobility of the polymer molecules. We found that the aluminum/epoxy composite containing 48 vol % aluminum-particle content possessed a high thermal conductivity and a high dielectric permittivity, but a low loss factor, a low electric conductivity, and a higher breakdown voltage.
