Published: April 2018

Pazopanib has been reported to induce proteinuria; however, no pathological findings have been reported. We herein report the case of a 31-year-old man with rhabdomyosarcoma treated with pazopanib who developed nephrotic syndrome. A renal biopsy revealed endothelial injury with podocyte changes. Based on the biopsy findings, we diagnosed the patient with nephrotic syndrome caused by pazopanib. Following the discontinuation of pazopanib, the patient's proteinuria gradually decreased without any specific treatment. We should be careful when encountering drug-induced proteinuria in patients taking pazopanib.

Oxidative Stress Early After Hematopoietic Stem Cell Transplant.

Transplant Cell Ther

January 2025

Division of Bone Marrow Transplantation and Immune Deficiency, Cincinnati Children's Hospital Medical Center, Cincinnati, OH; Department of Pediatrics, University of Cincinnati, Cincinnati, OH.

Background: HSCT conditioning regimens cause massive lysis of hematopoietic cells with release of toxic intracellular molecules into the circulation.

Objectives: To describe the response to oxidative stress early after hemopoietic stem cell transplantation (HSCT) and assess the association of early oxidative stress with later transplant outcomes.

Study Design: Key components of in the body's physiological response to oxidative stress were studied in a cohort of 122 consecutive pediatric allogeneic HSCT recipients.

Purpose: We aimed to investigate the role of gallic acid treatment on spinal cord tissues after spinal cord injury (SCI) and its relationship with endoplasmic reticulum (ER) stress by histochemical, immunohistochemical, and in-silico techniques.

Methods: Thirty female Wistar albino rats were divided into three groups: sham, SCI, and SCI+gallic acid. SCI was induced by dropping a 15-g weight onto the exposed T10-T11 spinal cord segment.

Inflammation-proliferation transition plays a key role in the successful healing of a common burn type, second-degree burn. Gynura procumbens in vitro adventitious root nanohydrogel is currently being studied for its immunomodulatory to improve reparative environment. Root production and nanohydrogel preparation was done respectively by in vitro propagation and emulsion/ solvent diffusion with carbomer as a polymer.

The pathogenesis and management of heatstroke and heatstroke-induced lung injury.

Burns Trauma

January 2025

Treatment Center for Traumatic Injuries, The Third Affiliated Hospital, Southern Medical University, No. 183, Zhongshan Avenue West, Tianhe District, Guangzhou, 510063, Guangdong, China.

In the past two decades, record-breaking heat waves have caused an increasing number of heat-related deaths, including heatstroke, globally. Heatstroke is a life-threatening systemic condition characterized by a core body temperature >40°C and the subsequent development of multiple organ dysfunction syndrome. Lung injury is a well-documented complication of heatstroke and is usually the secondary cause of patient death.

Background: Lipopolysaccharide (LPS)-induced apoptosis of lung microvascular endothelial cells (ECs) is the main reason of lung edema and acute lung injury (ALI) in septic conditions. Telocytes (TCs) are a distinct type of interstitial cells found around the lung microvasculature, which may protect ECs through the release of shed vesicles. However, whether TCs protect against LPS-induced EC apoptosis and ALI has not been determined.
