External Validation of the International IgA Nephropathy Prediction Tool in Older Adult Patients.

Purpose: The International IgA Nephropathy Prediction Tool (IIgAN-PT) can predict the risk of End-stage renal disease (ESRD) or estimated glomerular filtration rate (eGFR) decline ≥ 50% for adult IgAN patients. Considering the differential progression between older adult and adult patients, this study aims to externally validate its performance in the older adult cohort.

Patients And Methods: We analyzed 165 IgAN patients aged 60 and above from six medical centers, categorizing them by their predicted risk.

Sonographic measurement of renal size in patients undergoing chronic hemodialysis: Correlation with residual renal function.

Previous studies have reported that renal size may change when the function is compromised. However, it is not known whether sonographically measured renal size reflects the residual renal function (RRF) in patients undergoing chronic hemodialysis. A total of 140 patients undergoing chronic hemodialysis (≥3 months) were investigated in the present study.

Andrographolide induced acute kidney injury: analysis of 26 cases reported in Chinese Literature.

Aim: Some Chinese herbs have been known for their kidney toxicity. Andrographolide, the primary component of a traditional medicinal herb, Andrographis paniculata, is widely used in China for the treatment of upper and lower respiratory tract infection, and dysentery etc. The aim of the study was to identify and summarize any case of kidney injury attributed to its use in the Chinese literature.

Evaluation of Ca3Co2O6 as cathode material for high-performance solid-oxide fuel cell.

A cobalt-based thermoelectric compound Ca(3)Co(2)O(6) (CCO) has been developed as new cathode material with superior performance for intermediate-temperature (IT) solid-oxide fuel cell (SOFC). Systematic evaluation has been carried out. Measurement of thermal expansion coefficient (TEC), thermal-stress (σ) and interfacial shearing stress (τ) with the electrolyte show that CCO matches well with several commonly-used IT electrolytes.

Controllable synthesis of hollow bipyramid β-MnO(2) and its high electrochemical performance for lithium storage.

Three types of MnO2 nanostructures, viz., α-MnO2 nanotubes, hollow β-MnO2 bipyramids, and solid β-MnO2 bipyramids, have been synthesized via a simple template-free hydrothermal method. Cyclic voltammetry and galvanostatic charge/discharge measurements demonstrate that the hollow β-MnO2 bipyramids exhibit the highest specific capacity and the best cyclability; the capacity retains 213 mAh g(-1) at a current density of 100 mA g(-1) after 150 cycles.

Nitrogen-doped porous carbon nanofiber webs as anodes for lithium ion batteries with a superhigh capacity and rate capability.

Nitrogen-doped carbon nanofiber webs (CNFWs) with high surface areas are successfully prepared by carbonization-activation of polypyrrole nanofiber webs with KOH. The as-obtained CNFWs exhibit a superhigh reversible capacity of 943 mAh g(-1) at a current density of 2 A g(-1) even after 600 cycles, which is ascribed to the novel porous nanostructure and high-level nitrogen doping.

[Curative machanism of Shenle capsule on 5/6 nephrectomy rats].

Objective: To explore curative machanism of Shenle capsule on the 5/6 nephrectomy rats.

Method: Fibrin plate method was applied to examine activity of urinary plasminogen activator(PA). Semi-quantitative analysis was used to observe stained intensity and area of tissue-type plasminogen activator, urokinas-type plasminogen activator/ plasminogen activator inhibitor(tPA, uPA/PAI-1)in remnant renal tissue.
