Panaeolus punjabensis M. Asif, Q. Firdous, A. Izhar, Niazi & Khalid sp. nov. was collected from three different localities (Bahawalnagar, Kasur, and Lahore) in Punjab, Pakistan. Morphological observations phylogenetic analyses based on nuclear encoded internal transcribed spacers (ITS1-5.8S-ITS2 = ITS) D1/D2 domain of large subunit (28S) rDNA confirmed the taxonomic distinctness this specie...

When closed manipulation fails to restore articular congruity in comminuted, displaced fractures of the distal radius, open reduction and internal fixation is required. Results of surgical stabilization and articular reconstruction of these injuries are reviewed in this retrospective study of 49 patients with 52 displaced, intra-articular distal radius fractures. Forty-three patients (87%) with...

This study investigates the causal effect of first round China’s Great Western Development Strategy (GWDS) on total factor productivity (TFP) Chinese manufacturing firms employing geographic regression discontinuity design. It uses firm-level data from Annual Survey Industrial Firms (ASIF) database 1998 to 2007. To follow principle design and ensure validity our identification strategies, only ...

AIM The study was aimed at esthetic and functional results as well as patient tolerance after reconstruction with reconstruction plate. The follow-up ranged from 1 to 4 years. MATERIALS AND METHODS A retrospective study of 36 patients who had mandibular reconstruction with AO/ASIF stainless steel reconstruction plates after oncologic resection was evaluated. The indications and postoperative ...

We report our experience in 42 patients, using corticocancellous bone grafts and lag screw fixation for un-united scaphoid fractures. Using a grading system, we analysed the suitability of the method for three types of nonunion. We recommend the operation for the treatment of scaphoid nonunion, except where there is avascular necrosis of the proximal pole.
