Characterization of methane microseepage from natural gas reservoirs in mild climate: A case study of Xinchang gas field.

Methane microseepage from oil and gas fields significantly contributes to atmospheric methane level, making it a critical factor in global climate change. Therefore, accurate monitoring of surface flux and investigating migration mechanism are pivotal to evaluating and mitigating the impact of methane microseepage. In this study, methane microseepage from natural gas reservoirs in a mild climate was investigated, using Xinchang gas field as a case study.

Chinese herbal medicine for the treatment of small intestinal bacterial overgrowth (SIBO): A protocol for systematic review and meta-analysis.

Background: Chinese medicine has a unique theory and the Chinese herbal medicine treatment is based on the integral concepts and syndrome differentiation of the Traditional Chinese Medicine system. Although antibiotics remain the mainstay of SIBO treatment, various alternative or adjunctive therapies are available, including prokinetic agents, dietary interventions, probiotics, and herbal combinations. There is accumulating evidence demonstrating the antimicrobial properties of a growing number of herbs including garlic, black cumin, cloves, cinnamon, thyme, all-spices, bay leaves, mustard, and rosemary.

Distributed Event-Triggered Cooperative Control for Frequency and Voltage Stability and Power Sharing in Isolated Inverter-Based Microgrid.

The distributed cooperative control for frequency and voltage stability and power sharing in microgrid considering the limitation of communication network is concerned in this paper. Two types of novel event-triggered mechanism with distributed architecture are first proposed, which can greatly reduce the communication burdens among power source inverters. Based on the event-triggered schemes, distributed restoration mechanism is constructed, which can restore the frequency and voltage magnitude of microgrid and realize the fair utilization of all power sources with comparative less requirements for the transmission data.

[Hip arthroplasty for failed internal fixation of femoral neck fractures].

Objective: To investigate the result of hip arthroplasty for failed internal fixation of femoral neck fractures.

Methods: From June 2007 to January 2014, 29 cases who underwent hip arthroplasty for failed of internal fixation of femoral neck fractures were reviewed. There were 12 males and 17 females.

Protein Phosphatase 2A Mediates Oxidative Stress Induced Apoptosis in Osteoblasts.

Osteoporosis is one of the most common bone diseases, which is characterized by a systemic impairment of bone mass and fragility fractures. Age-related oxidative stress is highly associated with impaired osteoblastic dysfunctions and subsequent osteoporosis. In osteoblasts (bone formation cells), reactive oxygen species (ROS) are continuously generated and further cause lipid peroxidation, protein damage, and DNA lesions, leading to osteoblastic dysfunctions, dysdifferentiations, and apoptosis.

[Hip arthroplasty for the severe comminuted proximal femoral fracture with psilateral acetabulum fracture].

Objective: To investigate the results of hip arthroplasty for the treatment of severe comminuted proximal femoral fracture with ipsilateral acetabulum fracture.

Methods: From June 2007 to September 2013, 8 patients (8 hips) with severe comminuted proximal femoral fracture combined with ipsilateral acetabulum fracture were treated with hip arthroplasty. All patients were male and using biological prosthesis.

[Effectiveness of total hip arthroplasty for severe developmental dysplasia of hip in adults].

Objective: To evaluate the effectiveness of the total hip arthroplasty (THA) for severe development dysplasia of the hip (DDH) in adults.

Methods: Between July 2007 and January 2013, 25 patients (27 hips) with severe DDH underwent THA with cementless prosthesis. There were 10 males (11 hips) and 15 females (16 hips) with an average age of 38.
