Triple band gap coupled microstrip U-slotted patch antenna using L-slot DGS for wireless applications

Abstract: This paper presents a resonant type triple-band micro-strip U-slotted patch antenna with compact size. This is realized by using an L-slot loaded ground and U-slotted Patch antenna. A triple band antenna design is presented for antenna miniaturization at Wi-MAX/WLAN applications at 3.5 GHz (Wi-MAX) and 5.8 GHz and 7.5 GHz (WLAN) using L-slot defected ground structure (DGS) and U-slotted patch antenna. By adjusting the geometries and the sizes of these U-slot and L-slot structure, three different resonance modes can be effectively created for three distinct frequency bands; respectively. The antenna was designed using CST V.12 simulator.

Percutaneous autogenous bone marrow injection for delayed union or non-union of long bone fractures after internal fixation

Abstract: Objectives The aim of this study was to assess the results of percutaneous injection of autologous bone marrow in the treatment of fractures presenting with delayed union or non-union after internal fixation. Methods This prospective study was carried out at the Orthopeedics Department from June 2005 to June 2010. A total of 93 patients with delayed union and non-union (56 delayed unions and 37 non-unions) of the long bone were recruited from the Emergency and Outpatient Departments and treated with percutaneous autologous bone marrow injections. The clinical results of this study were rated on the basis of the criteria of union. All patients were followed for 24 months. Results All the fractures (delayed union and non-union) were united within 12 weeks. Most of the patients had discomfort at the donor site for few days; none had problems of persistent pain. The results were excellent in 68.81% (64/93) of cases, good in 19.35% (18/93) of cases, and poor in 11.82% (11/93) of cases. Conclusion Percutaneous autologous bone marrow injection is an effective and safe method for the treatment of diaphyseal non-union and delayed union. Thus, it is concluded that with an adequate amount of autologous bone marrow injection, successful union in delayed union and non-union of fractures of long bones can be achieved.

Dentistry and the myasthenia gravis patient: a review of the current state of the art

Abstract: Myasthenia gravis (MG) is a chronic neuromuscular disease characterized by muscular weakness and fatigability. Dental management of patients diagnosed with MG presents a challenge to the oral health care provider. The purpose of this article was to review the etiology, pathogenesis, diagnosis, and clinical signs and symptoms associated with MG, highlighting the role of the oral health care provider in the process of diagnosis and management of the oral and dental complications that might be associated with the disease, while avoiding myasthenic crisis. A discussion of the recent approaches to treatment of the disease and current research on MG is presented.
