Process Parameter Optimization for Laser Powder Bed Fusion of Fe-Si Alloy Considering Surface Morphology and Track Width of Single Scan Track.

A laser power bed fusion (L-PBF) manufacturing process was optimized by analyzing the surface morphology and track width of single scan tracks (SSTs) on Fe-3.4wt.%Si.

Tubeless percutaneous nephrolithotomy with non-absorbable hemostatic sealant (Quikclot®) versus nephrostomy tube placement: a propensity score-matched analysis.

The purpose of this study was to determine the efficacy and safety of tubeless percutaneous nephrolithotomy (PNL) using a non-absorbable hemostatic sealant (Quikclot(®)) as an adjunct compared to nephrostomy tube placement in patients exhibiting significant parenchymal bleeding following PNL. We identified 113 PNL cases performed between May 2011 and October 2014. For patients with insignificant parenchymal bleeding following stone removal, defined as a clear visualization of the surgical field at full irrigation of the nephroscope, tubeless PNL was performed.

CK2-NCoR signaling cascade promotes prostate tumorigenesis.

The aberrant expressions of casein kinase 2 (CK2) was found in prostate cancer patient and cell lines, but little is known of the detailed mechanisms implicated in prostate tumorigenesis. In this study, we report that both CK2 activity and CK2-mediated NCoR phosphorylation are significantly elevated in the androgen-independent prostate cancer cell line DU145 and PC-3 compared with RWPE1 and LNCaP cells. Increased phosphorylation inversely correlates with the mRNA level of the NCoR-regulated gene, interferon-γ-inducible protein 10 (IP-10).

Bladder neck injection of a polydimethylsiloxane-bulking agent under pneumovesicum for treatment of children with urinary incontinence: report of 3 cases.

Unlabelled: Abstract Introduction: To present the surgical technique and initial outcomes of bladder neck injection (BNI) of bulking agent under CO2-induced pneumovesicum to better visualize the bladder neck.

Subjects And Methods: Three children (one 12 year old and two 14 year olds) who underwent polydimethylsiloxane BNI under pneumovesicum for treatment of bladder neck incompetence were retrospectively reviewed. Patient diagnoses included an imperforate anus, joint hypermobility syndrome, and an ectopic ureter, respectively.

Retroperitoneoscopic partial nephrectomy in a horseshoe kidney.

A 21-year-old woman with a 4 cm enhancing cystic renal mass in the left moiety of a horseshoe kidney was treated through a retroperitoneal laparoscopic approach. The tumor was excised completely with cold scissors, and renal parenchyma suturing with a surgical bolster was done with Vicryl 2-0 sutures. Choosing the proper approach according to the location of the lesion and the surgeon's experience with both approaches are of importance in laparoscopic surgery in horseshoe kidney cases.

A prospective study of single-dose antibiotic prophylaxis in live donor nephrectomy.

Purpose: To perform a prospective analysis of the clinical outcomes of prophylactic antibiotic treatment before the standard surgical modality of living donor nephrectomy (LDN) without postoperative antibiotic treatment.

Materials And Methods: From November 2005 to June 2010, a total of 470 patients underwent LDN at our medical institution, and 280 of these patients were injected with 1 g cephalosporin 30 minutes before the operation. The group receiving prophylactic antibiotics was compared with a control group composed of 190 patients who received injections of 2 g cephalosporin per day for 5 days after the operation.
