The oxidation behavior of both Pd43Cu27Ni10P20 bulk metallic glass (Pd4-BMG) and its amorphous foam containing 45 pct porosity (Pd4-AF) was investigated over the temperature range of 343 K (70 C) to 623 K (350 C) in dry air. The results showed that virtually no oxidation occurred in the Pd4-BMG at T< 523 K (250 C), revealing the alloy’s favorable oxidation resistance in this temperature range. ...

BACKGROUND The Aral Sea region is a natural area seriously polluted by human activities. Recent surveillance revealed the increased prevalence of diverse chronic diseases in children. AIMS To investigate the function of renal tubules, which are most at risk of damage as a result of heavy metal intoxication, in children of the Aral Sea region. METHODS A group of 205 children living in Kazali...

OBJECTIVE To assess the success of buccal mucosal graft (BMG) urethroplasty by the dorsal onlay technique in long anterior urethral stricture (> 2 cm long) through the midline perineal incision. MATERIALS AND METHODS From January 1998 to December 2003, 43 patients with long anterior urethral strictures were managed by dorsal onlay BMG urethroplasty. After voiding trial, they were followed up ...

PURPOSE To describe the results of penile hypospadias repair using the Snodgrass method with buccal mucosa graft (BMG), supported by double dartos flap as a second layer. MATERIALS AND METHODS In a prospective cohort study, 21 consecutive patients underwent hypospadias repair using the Snodgrass method and BMG as the urethral plate, with the addition of double dartos flap for covering the neo...

Considering the special relation of human multiple myeloma (MM) to bones, it is of importance to clarify the early steps of bone involvement in this disease. In this work, using bone histomorphometry (including histoenzymologic and kinetic studies for the first time), we have evaluated the bone remodeling (i.e., bone resorption and bone formation rates) of 16 individuals with early MM in compar...

BACKGROUND Sodium palmitate causes apoptosis of β-cells, and the anti-apoptotic protein Bcl-2 has been shown to counteract this event. However, the exact mechanisms that underlie palmitate-induced pancreatic β-cell apoptosis and through which pathway Bcl-2 executes the protective effect are still unclear. METHODS A stable Bcl-2-overexpressing RINm5F cell clone (BMG) and its negative control (...

The use of biocompatible materials, including bulk metallic glasses (BMGs), for tissue regeneration and transplantation is increasing. The good mechanical and corrosion properties of Ti40Zr10Cu38Pd12 BMG and its previously described biocompatibility makes it a potential candidate for medical applications. However, it is known that surface properties like topography might play an important role ...
