Striking and widespread microglial activation in the brains of Southdown lambs with type II glucocerebrosidosis (neuronopathic Gaucher disease).

Glucocerebrosidosis (termed Gaucher disease in humans) is a lysosomal storage disease, caused by a deficiency of the enzyme glucocerebrosidase, which results in accumulation of the glycolipid substrate glucocerebroside in the macrophage-monocyte system. Three principal forms are recognized in humans, two being neuronopathic and resulting in neurodegeneration. Only two spontaneously arising cases have been described in domestic animals, one in a dog and the other in a flock of Southdown sheep.

Preclinical and clinical evaluation through serial colonoscopic evaluation of neratinib-induced diarrhea in HER2-positive breast cancer-A pilot study.

The irreversible pan-HER tyrosine kinase inhibitor neratinib is approved for patients with HER2-positive, early-stage and metastatic breast cancer (BC). Neratinib-associated diarrhea is the most common reason for early discontinuation. Preclinical studies identified mechanisms of neratinib-induced diarrhea and rationale for prophylactic and preventive measures.

Ferroptosis - a potential feature underlying neratinib-induced colonic epithelial injury.

Purpose: Neratinib, a small-molecule tyrosine kinase inhibitor (TKI) that irreversibly binds to human epidermal growth factor receptors 1, 2 and 4 (HER1/2/4), is an approved extended adjuvant therapy for patients with HER2-amplified or -overexpressed (HER2-positive) breast cancers. Patients receiving neratinib may experience mild-to-severe symptoms of gut toxicity including abdominal pain and diarrhoea. Despite being a highly prevalent complication in gut health, the biological processes underlying neratinib-induced gut injury, especially in the colon, remains unclear.

Study of the Structure of Hyperbranched Polyglycerol Coatings and Their Antibiofouling and Antithrombotic Applications.

While blood-contacting materials are widely deployed in medicine in vascular stents, catheters, and cannulas, devices fail in situ because of thrombosis and restenosis. Furthermore, microbial attachment and biofilm formation is not an uncommon problem for medical devices. Even incremental improvements in hemocompatible materials can provide significant benefits for patients in terms of safety and patency as well as substantial cost savings.
