Surgical Treatment of Piriformis Syndrome.

Background: Piriformis syndrome (PS) is an uncommon disease characterized by symptoms resulting from compression/irritation of the sciatic nerve by the piriformis muscle. Uncertainty and controversy remain regarding the proper diagnosis and most effective form of treatment for PS. This study analyzes the diagnostic methods and efficacy of conservative and surgical treatments for PS.

PMMA-Etching-Free Transfer of Wafer-scale Chemical Vapor Deposition Two-dimensional Atomic Crystal by a Water Soluble Polyvinyl Alcohol Polymer Method.

We have explored a facile technique to transfer large area 2-Dimensional (2D) materials grown by chemical vapor deposition method onto various substrates by adding a water-soluble Polyvinyl Alcohol (PVA) layer between the polymethyl-methacrylate (PMMA) and the 2D material film. This technique not only allows the effective transfer to an arbitrary target substrate with a high degree of freedom, but also avoids PMMA etching thereby maintaining the high quality of the transferred 2D materials with minimum contamination. We applied this method to transfer various 2D materials grown on different rigid substrates of general interest, such as graphene on copper foil, h-BN on platinum and MoS2 on SiO2/Si.

Comparison of Perioperative Blood Loss in Primary Non-cemented Total Hip Arthroplasty for Rapidly Destructive Coxarthrosis and Osteonecrosis of the Femoral Head.

Purpose: The purpose of this study is to compare the perioperative blood loss in primary non-cemented total hip arthroplasty (THA) performed for rapidly destructive coxarthrosis (RDC) with the perioperative blood loss in primary non-cemented THA for typical osteonecrosis of the femoral head (ONFH).

Materials And Methods: From January 2000 to December 2013, 19 patients were diagnosed with RDC (group 1) and 40 patients were diagnosed typical Ficat stage IV ONFH (group 2), comparison of perioperative blood loss between group 1 and group 2 in primary noncemented THA was done. Patients with preoperative usage of steroid or anticoagulants medication and with hemodynamic abnormal blood test results were excluded.

Treatment of subtrochanteric nonunion of the femur: whether to leave or to exchange the previous hardware.

Objective: Our aim was to compare the clinical results of two different methods for treatment of subtrochanteric nonunion: an additional fixation to the previous hardware, and exchange of previous hardware.

Methods: We retrospectively analyzed 19 cases of subtrochanteric nonunion, and compared clinical results from 10 cases (Group 1) with exchange of the previous hardware, and 9 cases (Group 2) with retained previous hardware and an additional fixation. Autogenous bone grafting were performed for all cases.

Postoperative mortality and factors related to mortality after bipolar hemiarthroplasty in patients with femoral neck fractures.

The purpose of this study was to determine the mortality rate and factors related to mortality in elderly patients with acute and monotraumatic femoral neck fractures. This study included 241 patients with femoral neck fractures after bipolar hemiarthroplasty. We analyzed the mortality rate and the relationship between postoperative mortality and risk factors, such as age, sex, body mass index, the time to surgery, and the Society of Anesthesiologists' score.

Modified posterior approach to total hip arthroplasty to enhance joint stability.

Unlabelled: We modified the posterior approach by preserving the external rotator muscles to enhance joint stability after primary THA. We asked whether this modified posterior approach would have a lower dislocation rate than the conventional posterior approach, with and without a repair of external rotator muscles. We retrospectively divided 557 patients (670 hips) who had undergone primary THA into three groups based on how the external rotator muscles had been treated during surgery: (1) not repaired after sectioning, (2) repaired after sectioning, or (3) not sectioned and preserved.

Bacterial diversity in selenium reduction of agricultural drainage water amended with rice straw.

Bacterial reduction of the Se oxyanions selenate [Se(VI)] and selenite [Se(IV)] to elemental selenium [Se0] is an important biological process in removing Se from drainage water. This study was conducted to characterize the molecular diversity of bacterial populations involved in Se reduction of drainage water amended with rice (Oryza sativa L.) straw and also to monitor the bacterial community shifts during the course of the study.

Kocuria marina sp. nov., a novel actinobacterium isolated from marine sediment.

An actinobacterial strain was isolated from marine sediment taken from the Troitsa Bay of the Gulf of Peter the Great, East Siberian Sea, and subjected to a taxonomic investigation. The isolate, designated KMM 3905T, was Gram-positive, aerobic, non-motile and coccoid. The strain tolerated up to 15 % NaCl in growth media, although its presence was not essential for growth.
