Background: Oliguric acute kidney injury (AKI) is one of the critical conditions which needs emergent treatment due to the lack of the capacity of excreting toxins and fluids, and plasma membrane bleb formation is considered as one of the characteristic morphologic alterations in ischemic AKI in both animal models and human. We present here an autopsy case with clear electron microscopy images capturing a definitive instance of blebbing in ischemic AKI.

Case Presentation: A 66-year-old man was admitted for oliguric AKI with nephrotic syndrome (NS).

We describe a case of sarcoidosis in a previously healthy 39-year-old man with the development of an acute kidney injury, requiring renal replacement therapy, as the first manifestation of the disease. The course of the disease was complicated by a сatheter-associated bloodstream infection. According to the histological examination of kidney biopsy samples, granulomatous interstitial nephritis was diagnosed.

Objectives: This study aimed to develop a prediction model for the detection of early sepsis-associated acute kidney injury (SA-AKI), which is defined as AKI diagnosed within 48 hours of a sepsis diagnosis.

Design: A retrospective study design was employed. It is not linked to a clinical trial.

School of Basic Medicine, Jiamusi University, Jiamusi 154007, PR China. Electronic address:

The possible involvement of mTOR/p70S6K signaling in mediating Fibrillin-1 expression during the transition from acute kidney injury (AKI) to chronic kidney disease (CKD) after cardiac arrest and cardiopulmonary resuscitation (CA/CPR). A CA/CPR AKI model was established using male C57BL/6 mice aged 8-12 weeks. The expression of Fibrillin-1 and activation of the mTOR/p70S6K signaling pathway in kidney tissues were assessed at different time points.
