BACKGROUND Shoulder arthroplasty is increasing in the United States. Reverse shoulder arthroplasty (RSA) has emerged as an alternative treatment for end-stage glenohumeral pathology. Until recently, administrative coding practices have not differentiated RSA from traditional total shoulder arthroplasty (TSA), and thus national procedural volume has been unknown. The purpose of this study was to...

Background: Recurrent spontaneous abortion (RSA) is a frequent reproductive problem, with three or more abortions affecting 1 to 2%, two or more abortions affecting up to 5% of women of reproductive age. Some polymorphisms are supposed to be etiology in this group.Vitamin D receptor (VDR) gene polymorphism seems to be a good ones to be searched due to their function on placenta. Materials and M...

background: human leukocyte antigen-e (hla-e)is a non-classical major histocompatibility complex (mhc) class i antigens which expressed on extra villous cytotrophoblast, which interacts with nkg2a, is an inhibitory receptor on natural killer (nk) cells and leading to down regulation of immune response in the maternal-fetal interface and provides maternal immune tolerance of the fetus. objective...

Many secreted proteins are synthesized with aminoterminal propeptides which are removed prior to secretion. There is increasing interest in the physiological roles of these propeptides, especially as mediators of intracellular protein trafficking. To investigate whether or not the propeptide of serum albumin offers an advantage in albumin secretion, we used oligonucleotide-directed mutagenesis ...

BACKGROUND AND PURPOSE Radiostereometric analysis (RSA) is a highly accurate tool for assessment of polyethylene (PE) wear in total hip arthroplasty (THA); however, PE wear measurements in clinical studies are often limited to plain radiographs. We evaluated the agreement between PE wear measured with PolyWare software, which uses plain radiographs, and by model-based RSA, which uses stereo rad...

Respiratory sinus arrhythmia (RSA, or high-frequency heart-rate variability) is frequently employed as an index of cardiac vagal tone or even believed to be a direct measure of vagal tone. However, there are many significant caveats regarding vagal tone interpretation: 1. Respiratory parameters can confound relations between RSA and cardiac vagal tone.2. Although intraindividual relations betwe...

The telecommunications industry is greatly concerned about customer churn due to dissatisfaction with service. This has started investing in the development of machine learning (ML) models for prediction extract, examine and visualize their customers’ historical information from a vast amount big data which will assist further understand needs take appropriate actions control churn. However, hi...

The Rivest–Shamir–Adleman (RSA) cryptosystem is currently the most influential and commonly used algorithm in public-key cryptography. Whether security of RSA equivalent to intractability integer factorization problem an interesting issue mathematics Coron May solved above fundamental proved polynomial-time equivalence computing secret key factoring. They demonstrated that modulus N=pq can be f...
