| 1 | Analysis of the formation conditions and characteristics of interphase and random vanadium precipitation in a low-carbon steel during isothermal heat treatment显示文摘The characteristics of nanosized precipitates in steels depend on the heat-treatment parameters. The effects of characteristics of vanadium precipitates formed during isothermal heat treatment on the hardness of the ferrite matrix in low-carbon vanadium-alloyed steel were investigated through analysis of transmission electron microscopy images and microhardness measurements. The results show that, during isothermal holding in the temperature range from 675 to 750℃, only interphase precipitation occurs, whereas only random precipitation occurs in the ferrite matrix during holding at 600℃. Furthermore, during isothermal heat treatment between 600 and 675℃, both random and interphase precipitates occurred in the ferrite. Nanoscale vanadium carbides with different atomic ratios of vanadium(V) and carbon(C) were the dominant precipitates in the random and interphase precipitates. The sizes of random precipitation carbides were smaller than those of interphase ones. Also, the sample isothermally heat treated at 650℃ for 900s exhibited a higher hardness with a narrower hardness distribution. | Sayed Ghafar Hashemi B.Eghbali | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，3： | 4 |
| 2 | Methods to shorten the duration of an external fixator in the management of tibial infections显示文摘Massive segmental bone loss due to chronic osteomyelitis represents a considerable challenge to orthopedic surgeons and is a limb threatening condition.The only option available in such a clinical situation is segment transport using the Ilizarov technique of distraction osteogenesis;yet the most common problem in cases of bone transport with the Ilizarov technique in massive bone loss,is the long duration of the fixator.In addition to autologous bone grafting,several mechanical,biologic,and external physical treatment modalities may be employed to promote bone formation and maturation during segment transport in osteomyelitis patients.Mechanical approaches include compressive loading of the distraction regenerate,increased frequency of small increments of distraction,and compression-distraction.Intramedullary nailing and hemicorticotomy can reduce the time in external fixation;however,these techniques are associated with technical difficulties and complications.Exogenous application of low-intensity pulsed ultrasound or pulsed electromagnetic fields may shorten the duration of external fixation.Other promising modalities include diphosphonates,physician-directed use(off-label use)of bone morphogenetic proteins,and local injection of bone marrow aspirate and platelet gel at the osteotomy site.Well-designed clinical studies are needed to establish safe and effective guidelines for various modalities to enhance new bone formation during distraction osteogenesis after segment transfer. | Khaled M Emara Khaled Abd Al Ghafar Mohamed Ahmed Al Kersh | 2011 | World Journal of Orthopedics2011，2，9： | 4 |
| 3 | Vulvar granular cell tumor显示文摘Granular cell tumors are rare,usually benign,soft tissue neoplasms of neural origin.They occur more often in females than males,the peak age incidence is in the fourth through fifth decades.They can occur anywhere in the body with up to 15% situated in the vulva.The commonest presentation is as an asymptomatic mass.Microscopic findings are usually sufficient,but immunohistochemistry can also be helpful in confirming the diagnosis.The vulvar tumors are benign in 98% of cases with 2% reported as malignant.In this case report we describe a woman with a granular cell tumor confirmed by biopsy who underwent excision of the mass but with focal extension to the resection margin on microscopy.Our recommendation of re-excision was declined.Since it is not uncommon with these tumors to find groups of tumor cells extending beyond the macroscopic limits of growth,we conclude that it is advisable to have margins assessed intraoperatively by frozen section such that further excision can be performed for positive margins.Our patient has been followed for 18 mo without recurrence,should the tumor recur,re-excision,with frozen section control,is indicated.Recurrence rates are reported as 2%-8% with clear margins and 20% with positive margins. | Michel E Rivlin G Rodney Meeks Mohamed A Ghafar Jack R Lewin | 2013 | World Journal of Clinical Cases2013，1，4： | 2 |
