To date, 18 cases have been published in the literature as single-case reports, based chiefly on CD99 positivity (17 patients). Molecular confirmation by fluorescence in situ hybridization was performed in 9 patients, and FLI1 immunohistochemical (IHC) analysis was not performed in any of these published cases. Herein, we present thirteen patients of more comprehensive primary round cell sarcomas of the urinary bladder with EWSR1 rearrangement. selleck Clinicopathologic parameters including demographics; clinical presentation; histopathologic, IHC, and molecular profiles; and management and follow-up data of 13 patients with primary round cell sarcomas with EWSR1 rearrangement (Ewing family of tumor) of the urinary bladder were analyzed. The studied patients (n = 13) included 6 ing from 5 to 24 months). Six patients either died of disease (n = 3) or other causes (n = 3). Five patients were alive with metastases to the liver (n = 1), liver and lung (n = 2), liver and abdominal wall (n = 1), and kidney (n = 1). Based on our experience with the largest series to date and aggregate of the published data, ES/round cell sarcomas with EWSR1 rearrangement occurring in the bladder have bimodal age distribution with poor prognosis despite aggressive therapy. Owing to its rarity and age distribution, the differential diagnosis is wide and requires a systematic approach for ruling out key age-dependent differential diagnoses aided with molecular confirmation.Wound management has attracted significant interest in view of the broad demand market. Dressings are playing crucial roles in wounds management because they can protect the wound from external infection, and accelerate the healing process. Among the various available dressing materials, hydrogels have appealed increasing attention for their tunable chemical, physical and biological properties, and three-dimensional cross-linked polymer networks which can absorb and retain large amount of water. Although hydrogels have become representative of soft dressing materials, the design of conventional hydrogel materials still needs improvement. Nowadays, novel self-healing hydrogel wound dressings hopefully optimize the defects of mechanical property over conventional hydrogel thus extend their usage lifespan due to their potential of autonomous self-recovery against damage, which have gained much momentum recently. This presented review mainly focuses on research status of self-healing hydrogel for wound management. The polymers suitable for hydrogel forming, and the appropriate molecular design of the hydrogel network for achieving self-healing properties are discussed, followed by the applications of self-healing hydrogel as wound dressing. Finally, we discuss the future perspectives of self-healing hydrogel as wound dressing, and provide the recommendations for its possible developing orientation.Dry modification of starch, especially by microwave-assisted heating, has attracted increasing attention due to its various advantages, including energy saving, high conversion, rapidity, and avoidance of volatile organic solvents in organic synthesis. This work focuses on two fundamental issues 1) effect of starch microstructure on dry modification; 2) effect of acid anhydride in solid and liquid states on the dry reaction, since their interfaces with solid starch are significantly different. Cornstarches with different amylose/amylopectin ratios were used to demonstrate the effect of starch microstructure, while two acid anhydrides, maleic (solid) and acetic (liquid) anhydrides, were used to study the reaction mechanisms. FTIR, SEM, XRD, and DSC were used to study the performance of modified starches and the mechanisms. It was found that
