In this review we examine the advantages of genetically engineered drug delivery systems with emphasis on ELP and SLP constructions. Methods for fabrication and relevant biomedical applications will also be discussed.Controlled nano-systems for drug delivery are designed to deliver therapeutical drugs to desirable sites on demand. Due to the diverse physiological functions of peptides, it is reasonable to introduce peptides into anti-tumor nano-system. The integration of peptides into nanomaterials has complementary advantages, which not only avoids the rapid degradation of peptides in vivo, but also improves the intelligence and functionality of the nano-system. We summarized the functional peptides with targeting and stimulus-responsive properties, and the present review outlined the most relevant and recent developed peptide-based multifunctional nanomaterials for tumor therapy. To report current results of a new surgical technique, tubularized reconstructed plate urethroplasty (TRPU) in distal hypospadias repair which allows the tubularization of urethral plate without incision or grafting. This study is a prospective single surgeon series. Between January 2019 and March 2020, total of 158 patients underwent hypospadias repair, and 29 selected patients had TRPU procedure. Demographic data, duration of follow-up, complications were recorded. A vertical incision is made starting from halfway up the glans. This incision creates a diamond like defect which enables wedge removal of a segment of spongiosum tissue from the base of urethral plate extending to the hypospadiac meatus. Vertica
