An unusual cause of rapidly progressive glomerulonephritis associated with ANCA vasculitis and ovarian malignancy - a relapse 39 years after initial treatment.

A 69-year-old woman presented with severe anemia, proteinuria, microscopic hematuria and rapidly progressive renal failure. She was admitted to the nephrology department due to severe deterioration of renal function with complaints of malaise, fever, dry cough and occasional epistaxis that appeared 2 months prior to admission. Histopathologic examination of a specimen from kidney biopsy and immunologic findings revealed ANCA positive pauci-immune crescentic glomerulonephritis.

Influence of Process Parameters on the Characteristics of Additively Manufactured Parts Made from Advanced Biopolymers.

Over the past few decades, additive manufacturing (AM) has become a reliable tool for prototyping and low-volume production. In recent years, the market share of such products has increased rapidly as these manufacturing concepts allow for greater part complexity compared to conventional manufacturing technologies. Furthermore, as recyclability and biocompatibility have become more important in material selection, biopolymers have also become widely used in AM.

Evaluation of Boride Layers on C70W2 Steel Using a New Approach to Characterization of Boride Layers.

In this study, boride layers on C70W2 steel, obtained by boronizing at temperatures ranging from 870 to 970 °C and durations from 4 to 8 h, were investigated. The characterization of the layers was carried out using a new approach based on the change in the volume fraction of the boride phase. Analysis of the change in volume fraction showed that an increase in temperature and duration resulted in thicker layers, with temperature having a greater influence.
