Background: The Global Unite Shoulder System is the next generation of implant from the Depuy Global Shoulderline. The primary feature of the Global Unite is adaptability through the interchangeable modular bodies, modular suturecollars, and stems. Short-term functional and radiographic outcomes of the Global Unite Platform Shoulder Systemwere assessed as well as complication and revision rates...

The recognition of small molecules in hydrophobic cavities aqueous medium is a fundamental process molecular biology. Previously, we described the synthesis and conformational switching enantiopure alleno-acetylenic cage receptors as well their application model systems to study detail interplay space occupancy, conformation, complexation, chiral organic solvents. Now, report three functionaliz...

The large-scale conformation of DNA molecules plays a critical role in many basic elements of cellular functionality and viability. By targeting the structural properties of DNA, many cancer drugs, such as anthracyclines, effectively inhibit tumor growth but can also produce dangerous side effects. To enhance the development of innovative medications, rapid screening of structural changes to DN...

purpose: to evaluate the success rate of vitrectomy in giant retinal tears (gtr) and factors influencing it. methods: in an interventional case series, hospital records of 68 eyes of 63 patients operated for grt were reviewed. standard three port vitrectomy plus placement of an encircling band, retinopexy, and internal tamponade was performed for all eyes. possible influencing factors including...

the 1h and natural-abundance 13c-nmr spectra of 1-thiacyclooctan-3-one (1) have been measured from 25 to -100°c. coalescence is observed in the 1h-nmr spectra of (1) at about -80°c, and attributed to ring inversion in a boat-chair conformation, which is the predominant conformation of (1). the free energy of activation (dg¹) for this process is 9.2±0.2 kcal/mol. the 13c-nmr spectra of (1) is te...

statement of problem: recognition and determination of facial and dental midline is important in dentistry. currently, there are no verifiable guidelines that direct the choice of specific anatomic landmarks to determine the midline of the face or mouth. objectives: the purpose of this study was to determine which of facial anatomic landmarks is closest to the midline of the face as well as tha...

the presence of anatomic variations of paranasal sinuses must be noted in order to attain a full understanding and accurate diagnosis of chronic sinusitis. the frequency of anatomic variations in chronic sinusitis is different in various studies. the purpose of this study is to assess the frequency of anatomic variations in chronic sinusitis patients admitted to otolaryngology ward of shahid sa...

OBJECTIVE Compared with other lower cranial nerves, the glossopharyngeal nerve (GPhN) is well hidden within the jugular foramen, at the infratemporal fossa, and in the deep layers of the neck. This study aims to disclose the course of the GPhN and point out landmarks to aid in its exposure. METHODS The GPhN was studied in 10 cadaveric heads (20 sides) injected with colored latex for microsurg...
