New methods of diffusion metallization AISI W1-7 steel have been developed. The paper proposes a comparative analysis the properties and characteristics after three chemical heat treatment: nitriding, nitrogen titration by physical deposition from gas phase, chromium plating with subsequent titanium alloys. results are presented as comprehensive coatings: metallographic, micro-X-ray spectral, X...

BACKGROUND The position of plate fixation for clavicle fracture remains controversial. Our objective was to perform a comprehensive review of the literature and quantify the surgical parameters and clinical indexes between the anterior inferior plating and superior plating for clavicle fracture. METHODS PubMed, EMBASE, and the Cochrane Library were searched for randomized and non-randomized s...

BACKGROUND AND PURPOSE Although plating is considered to be the treatment of choice in distal tibia fractures, controversies abound regarding the type of plating for optimal fixation. We conducted a systematic review to evaluate and compare the outcomes of locked plating and non-locked plating in treatment of distal tibia fractures. PATIENTS AND METHODS A systematic review was conducted using...

Many laboratories are experiencing growing shortages of trained microbiology technologists and technicians. Consequently, there is considerable interest in new automation that could potentially lessen labor demands for specimen processing. In this study, we present the first published evaluation of a new microbiology instrument, the Walk Away Specimen Processor (WASP), manufactured by Copan, In...

BACKGROUND To compare risk of carpal tunnel syndrome (CTS) in distal radius fracture (DRF) patients after 7 treatments using bridging external fixation (BrEF), non-bridging external fixation (non-BrEF), plaster fixation, K-wire fixation, dorsal plating fixation, volar plating fixation, and dorsal and volar plating by performing a network meta-analysis. MATERIAL AND METHODS An exhaustive search ...

Ni-B binary coating and Ni-B-W ternary were successfully prepared on titanium alloy (TC4) substrates by electroless plating to improve the hardness wear resistance, followed annealing treatment for better mechanical properties tribological properties. The morphology, composition, microstructure, properties, behaviors of coatings characterized. Both as-plated amorphous, while composition morphol...

The systems and software development industry is characterized by a paradigm of project failure. There are various factors that can lead to project failure .One such factor is gold plating. Gold plating can cause various problems in the projects like increase in project complexity, use of more resources, and increase in time and budget of the project and many more. If effects of gold plating ar...

background: the well documented source for adult multipotent stem cells is spermatogonial stem cells (sscs). they are the foundation of spermatogenesis in the testis throughout adult life by balancing self-renewal and differentiation. the aim of this study was to assess the effect of percoll density gradient and differential plating on enrichment of undifferentiated type a spermatogonia in diss...

A new method of quantifying Candida spp. and Torulopsis glabrata suspensions, the spiral inoculation system, was studied to compare its accuracy, efficiency, and cost with the standard pour plating and spread plating methods. Concentrations of yeast suspensions ranging from 10(2) to 10(5) CFU were quantified simultaneously by the three methods. Linear regression analysis was used to determine t...

BACKGROUND Management of deep sternal wound infection (DSWI) in cardiac surgical patients still remains challenging. A variety of treatment strategies has been described. Aim of this cohort study was to analyse two different treatment strategies for DSWI: titanium sternal plating system (TSFS) and muscle flap coverage (MFC). METHODS Between January 2007 and December 2011, from 3122 patients u...
