Abstract:

Traction substation reliability is of vital importance for railway transportation safety. To illustrate traction substation reliability, irreparable and reparable reliability models of three types of traction substation Electrical main connection have been established. Based on analysis of simple series and parallel reliability system, system irreparable reliability model is analyzed. The ways of how to get mean time to failure (MTTF) and mean time to first failure (MTTFF) of reparable system are achieved. By comparative analysis of the value of MTTF and MTTFF among three kinds of traction sub

Background: Superior capsular reconstruction (SCR) was recently introduced as a treatment for irreparable superior rotator cuff tears in younger patients. Purpose/Hypothesis: The purpose was to assess the biomechanical strength of 3 methods for fixation of the graft to the glenoid for SCR. It was hypothesized that a 4-anchor technique would provide greater load to failure than 3-anchor techniques. Study Design: Controlled laboratory study.

Abstract:

A methodology was developed for estimating the remaining life of a nonoverlaid continuously reinforced concrete pavement. The models presented use several key predictors: the early-age crack distribution pattern in the concrete caused by volumetric changes, the coarse aggregate type used, and the presence or absence of a swelling subgrade that will accelerate the rate of failure development in later life due to dynamic loadings. Considering these factors, the models can accurately estimate the additional 18-kip equivalent single axle loads (ESALs) that will take the pavement from its current c

In Moira Buffini's Welcome to Thebes (2010) Antigone fails to reach her tragic destiny, the city of Thebes fails to become an autonomous democratic state, and the audience fails to witness the splendour of the ancient heroine.

Abstract:

Background: Superior capsular reconstruction (SCR) is an alternative to reverse shoulder arthroplasty for irreparable rotator cuff tears (IRCTs). The reconstructed capsule acts as a static restraint to prevent superior migration of the humeral head. Traditional SCR uses a fascia lata autograft, which has shown failure at the greater tuberosity. An Achilles tendon–bone allograft has been proposed to improve the failure rate. Purpose: To evaluate the surgical outcomes of SCR using an Achilles tendon–bone allograft for the treatment of IRCTs. Study Design: Case series; Level of evidence, 4. Metho

Abstract:

Heart failure commonly results from an irreparable damage due to cardiovascular diseases (CVDs), the leading cause of morbidity and mortality in the United States. In recent years, the rapid advancements in stem cell research have garnered much praise for paving the way to novel therapies in reversing myocardial injuries. Cell types currently investigated for cellular delivery include embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), and adult stem cell lineages such as skeletal myoblasts, bone-marrow-derived stem cells (BMSCs), mesenchymal stem cells (MSCs), and cardiac ste

BACKGROUND: Recently, reverse total shoulder arthroplasty (RTSA) has been accepted as a main treatment option in irreparable massive rotator cuff tear with cuff arthropathy. The purpose of this study was to evaluate the early complication incidence and the preliminary clinical results of RTSAs performed in single institute.METHODS: Fifty-seven RTSAs (56 patients) were performed between April 2011 and March 2013. The indications for RTSA were cuff tear arthropathy and irreparable massive rotator cuff tear with or without pseudoparalysis. Exclusion criteria were revision, preoperative infections

Abstract:

Cilostazol is effective in controlling pathophysiological pathways similar or identical to those involved in nonmaturation and failure of the arteriovenous access. This case–control study examined whether cilostazol would improve maturation rates and durability of vascular access for hemodialysis. The treatment group included 33 patients who received cilostazol for ≥30 days prior to creation of a dialysis access and continued with cilostazol therapy for ≥60 days after surgery. The matched (gender, age, race, diabetes, and the year of surgery) control group included 116 patients who underwent t

Abstract:

We report the case of a 70-year-old male with Parkinson’s disease (PD) and recurrent traumatic left shoulder dislocations. This case is rare because (1) he had a massive irreparable rotator cuff tear and end-stage arthritis (i.e., rotator cuff-tear arthropathy) of the same shoulder and (2) his shoulder was ultimately reconstructed with a reverse total shoulder arthroplasty (RTSA). His first dislocation occurred after a fall. Recurrent shoulder dislocations occurred despite successful closed reduction and physical therapy. Initial surgical treatment included an open capsular-labral reconstructi

Introduction Primary reverse shoulder arthroplasty has been reported to provide good outcomes. The majority of designs utilize a large portion of the glenoid. Some studies have reported worrisome rates of notching and stress fractures of the acromion or scapular spine. The purpose of this study was to determine the outcome and complications of a bone-preserving reverse prosthesis with limited ingrowth glenoid surface paired with an onlay humeral component.

Abstract Abstract 2197 Poster Board II-174 Background: Imatinib is very effective for patients with CML in chronic phase (CP). While some patients (pts) may fail therapy with imatinib (because of resistance or intolerance), effective salvage therapy is available with new generation TKI (dasatinib, nilotinib, bosutinib). Currently the efficacy of each therapy is judged by their individual impact on overall survival (OS) and event free survival (EFS). However calculations of EFS for a patient does not take into account the effect of successful salvage therapy with subsequent TKI. We therefore st

Abstract:

The rotator cuff is a complex anatomical and biomechanical structure which allows stabilization of the shoulder joint in the correct position and movements in it. The rotator cuff tears remain the most frequent injury as compared to those of other anatomical structures of the shoulder joint and reach the incidence of 21%, according to a number of authors. Such injuries are prone to inducing a fat replacement of muscle tissues in elderly patients against the background of degenerative changes in the structure of the rotator cuff. These injuries are hard-to-heal, and the incidence of relapses af

Abstract:

Recovery from injury is usually accompanied by cell replication, in which new cells replace those irreparably damaged. After acute renal failure, normally quiescent kidney cells enter the cell cycle, which in tubule segments is accompanied by the induction of cell cycle inhibitors. We found that after acute renal failure induced by either cisplatin injection or renal ischemia, induction of the p21 cyclin-dependent kinase (cdk) inhibitor is protective. Mice lacking this gene developed more widespread kidney cell death, more severe renal failure, and had reduced survival, compared with mice with
