Uniaxial tensile tests were conducted on a Zr-based bulk metallic glass (BMG) with a nominal composition of Zr52.5Cu17.9Ni14.6Al10.0Ti5.0 (at.%). An infrared (IR) camera was utilized in situ during tensile testing to observe shear band evolution and fracture in the BMG. This unique visualization technique revealed that the temperature along the axis of shear band propagation constantly decrease...

Cu50Zr45Al₅ bulk metallic glass (BMG) presents high fracture strength. For improving its plasticity and controlling its mechanical properties, superficial dealloying of the BMG was performed. A composite structure containing an inner rod-shaped Cu-Zr-Al amorphous core with high strength and an outer dealloyed nanoporous layer with high energy absorption capacity was obtained. The microstructure...

Objectives. To review the available literature describing the three most common approaches for buccal mucosal graft (BMG) augmentation during reconstruction of bulbar urethral strictures. Due to its excellent histological properties, buccal mucosa graft is now routinely used in urethral reconstruction. The best approach for the placement of such a graft remains controversial. Methods. PubMed se...

Surgical treatment of urethral strictures is a continually evolving process, and currently there is renewed controversy over the best means of urethral reconstruction. Buccal mucosa graft (BMG) has gained much interest because of its excellent short and long-term results, low post-operative complication rate, and relative ease of use [1,2]. A number of series reported success rate of 87-90% usi...

Due to cholestasis or adverse drug effects, the excretion of bilirubin conjugates can decrease; therefore, the level of bilirubin (B) and bilirubin glucuronides (BGs) increases in the serum with the concomitant shift of bilirubin diversus monoglucuronide (BDG/BMG) equilibrium. The aim of this study was to utilize the collagen-sandwich culture of hepatocytes as an in vitro model for studying B c...

Urethroplasty may involve the use of tissue substitution including buccal mucosa graft (BMG), penile fasciocutaneous flaps, or skin grafts. Stricture recurrence and fistula formation are some uncommon complications that can result from surgery. The development of squamous cell carcinoma (SCC) after BMG substitution urethroplasty is a new complication that we encountered that has not been descri...

BACKGROUND Conventional dentoalveolar osseous reconstruction often involves the use of graft materials with or without barrier membranes. OBJECTIVE To evaluate the efficacy of bone induction by bone matrix gelatin (BMG), delivered on an absorbable collagen sponge (ACS), compared to a placebo (ACS alone) in human alveolar socket defects. METHODS 20 alveolar sockets from 10 healthy adults wer...

Objectives. To compare the outcome of dorsal buccal mucosal graft (BMG) substitution urethroplasty by dorsal urethrotomy approach with ventral urethrotomy approach in management of stricture urethra. Methods and Materials. A total of 40 patients who underwent dorsal BMG substitution urethroplasty were randomized into two groups. 20 patients underwent dorsal onlay BMG urethroplasty as described ...
