Background: Endothelial progenitor cells (EPCs) have been well-studied for their differentiation potential and paracrine activity in vitro and in experimental animal studies. EPCs are the precursors of endothelial cells (ECs) and a rich source of pro-angiogenic factors, and hence, possess enormous potential to treat ischemic heart through myocardial angiogenesis. Their proven safety and efficacy observed during the pre-clinical and clinical studies have portrayed them as a near ideal cell type for cell-based therapy of ischemic heart disease.

Integrating sustainability goals into the selection of suitable soil stabilization techniques is a global trend. Several bio-inspired and bio-mediated soil stabilization techniques have been recently investigated as sustainable alternatives for traditional techniques known for their high carbon footprint. Enzyme Induced Carbonate Precipitation (EICP) is an emerging bio-inspired soil stabilization technology that is based on the hydrolysis of urea to precipitate carbonates that cement sand particles.

Waste management involves various procedures and resources for proper handling of waste materials in compliance with health codes and environmental regulations. Landfills are one of the oldest, most convenient, and cheapest methods to deposit waste. However, landfill utilization involves social, environmental, geotechnical, cost, and restrictive regulation considerations.

Doxorubicin (DOX) is a chemotherapeutic agent widely used in human malignancies. Its long-term use cause neurobiological side effects. The aim of the present study was to investigate the prophylactic effect exerted by daily administration of ellagic acid (EA) and rosmarinic acid (RA) on DOX-induced neurotoxicity in rats.

The anticancer drug doxorubicin causes testicular toxicity as an undesirable effect. The present study was undertaken to investigate the possible protection of ellagic acid and rosmarinic acid during doxorubicin administration. For this purpose eight groups of male Sprague-Dawley rats were used (n = 10), one group received vehicle served as control, and other groups received 5 mg/kg doxorubicin twice a week for 2 weeks for a cumulative dose of 20 mg/kg, ellagic acid (10 mg/kg/day, 14 consecutive days p.

Objective: To evaluate the sensitivity and specificity of abdominal computed radiography (CR) for the diagnosis of enterolithiasis in horses and to examine how these parameters are affected by the number and anatomic location of enteroliths and by gas distension of the gastrointestinal tract.

Design: Retrospective case series.

Animals: Horses ? 1 year old that underwent abdominal CR and subsequent exploratory laparotomy or postmortem examination.
