Tidal-driven NO emission is a stronger resister than CH to offset annual carbon sequestration in mangrove ecosystems.

The mangrove ecosystems store a significant amount of "blue carbon" to mitigate global climate change, but also serve as hotspots for greenhouse gases (GHGs: CO, CH and NO) production. The CH and NO emissions offset mangrove carbon benefits, however, the extent of this effect remains inadequately quantified. By applying the 36 h time-series observations and mapping cruises, here we investigated the spatial and temporal distribution of GHGs and their fluxes in Dongzhaigang (DZG) bay, the largest mangrove ecosystem in China, at tidal and monthly scales.

Successful extracorporeal membrane oxygenation for heart failure after adolescent idiopathic scoliosis surgery.

Purpose: Spine surgery, particularly deformity correction, is associated with a high risk of peri-operative or post-operative complications, and these complications can lead to catastrophic consequences. This case report will present the etiology and treatment process of the peri-operative cardiac arrest during scoliosis correction surgery.

Method: In this report, we present a case of cardiac arrest during posterior correction surgery in a 17-year-old female patient with adolescent idiopathic scoliosis.

Outcomes after arthroscopic treatment for scaphoid nonunion using ipsilateral radius bone graft and a headless compression screw: a comparison between the patients with and without avascular necrosis.

Purpose: To determine whether avascular necrosis can affect clinical outcomes or the union incidence after arthroscopic bone grafting for the treatment of scaphoid nonunion.

Methods: This retrospective comparative study included thirty-four patients with scaphoid nonunion that underwent arthroscopic bone graft from the ipsilateral radius and internal fixation. The patients were divided into two cohorts (group A, with avascular necrosis, n = 15; group B, without avascular necrosis, n = 19) based on pre-operative magnetic resonance imaging findings.

Are functional outcomes and reoperation rates really better than those of cementless stems in displaced femoral neck fractures? An updated systematic review and meta-analysis of randomized controlled trials in current-generation stem designs.

Background: The aim of the study was to conduct a systematic review and meta-analysis to compare the functional outcomes and reoperation rates of cemented and cementless hip arthroplasty for treating displaced femoral neck fractures in elderly patients.

Methods: Systematic searches were conducted of literature up to December 2018 on PubMed, Embase, Cochrane, and Web of Science for randomized controlled trials (RCTs) concerning current-generation stem designs only. Two reviewers independently determined eligibility, extracted the outcome data and assessed the risk of bias of eligible studies.

Enantioselective vinylogous aldol/lactonization cascade reaction between β,γ-unsaturated amides and trifluoromethyl ketones: facile access to chiral trifluoromethyl dihydropyranones.

An efficient asymmetric vinylogous aldol/lactonization cascade reaction between β,γ-unsaturated amides and trifluoromethyl ketones has been developed. Using a chiral cyclohexanediamine-based tertiary amine-thiourea catalyst, optically active trifluoromethyl dihydropyranones have been constructed in moderate-to-excellent yields (up to 99%) with excellent stereoselectivities (96-> 99.5% ee).

Dynamic Hip Screw with Trochanter-Stabilizing Plate Compared with Proximal Femoral Nail Antirotation as a Treatment for Unstable AO/OTA 31-A2 and 31-A3 Intertrochanteric Fractures.

Background: The dynamic hip screw (DHS) with the addition of an angular stable trochanter-stabilizing plate (TSP) has been considered the ideal treatment for the unstable intertrochanteric fracture type. However, there have been few comparisons between DHS+TSP augmentation with intramedullary (IM) nailing. The aim of this retrospectively registered study was to compare the clinical outcomes of patients with the unstable type of intertrochanteric fractures treated with DHS+TSP or IM nailing (proximal femoral nail antirotation (PFNA)).

Is all-inside with suspensory cortical button fixation a superior technique for anterior cruciate ligament reconstruction surgery? A systematic review and meta-analysis.

Background: To compare the clinical results of all-inside anterior cruciate ligament reconstruction (ACLR) using suspensory cortical button fixation and full tibial tunnel drilling.

Methods: Systematic searches were conducted of published literature up to November 2019 on PubMed, Embase, and Cochrane for studies comparing all-inside ACLR using suspensory cortical button fixation and full tibial tunnel ACLR. Two reviewers independently determined eligibility, extracted the outcome data, and assessed the risk of bias of the eligible studies.

Surgical treatment of postburn heterotopic ossification around the elbow: Three case reports.

Rationale: Heterotopic ossification (HO), which is defined as the formation of new bone in tissues that do not normally ossify, is an infrequent yet debilitating complication of burns. Herein, we report three patients who suffered from elbow HO after burn injury due to a dust explosion event. This is a case report that includes the most cases involved in a single mass casualty incident in the presented literature.
