Abstract:

Background: Periprosthetic bone remodelling may increase fracture risk and deplete bone stock around hip implants. These changes are in part caused by implant design, advocating an early evaluation of bone remodelling properties of new implants. This can be done by repeated dual-energy x-ray absorptiometry (DXA) measurements. We know that radiopaque cement falsely elevates bone mineral density (BMD) in single measurements, however, its impact on repeated measurements, i.e. BMD changes is unexplored. We have therefore investigated whether the presence of radiopaque cement affect repeated BMD me

Abstract:

Poly(methyl methacrylate) (PMMA) bone cements have been widely used in clinical practices. In order to enhance PMMA’s imaging performance to facilitate surgical procedures, a supplementation of radiopaque agent is needed. However, PMMA bone cements are still facing problems of loosening and bacterial infection. In this study, a multifunctional coating to simultaneously encapsulate drug and prevent the infection of radiopaque agent has been developed. Barium sulfate (BaSO4), a common radiopaque agent, is used as a substrate material. We successfully fabricated porous BaSO4 microparticles, then

Abstract:

A new microcatheter-delivered, highly-flexible, fully-retrievable intracranial stent has been developed in order to facilitate the endovascular treatment of wide-necked aneurysms, though it might also prove useful for other intracranial pathology. The nitinol stent has radiopaque proximal and distal markers, is available in a wide range of sizes and is as flexible as a micro-guidewire. It is electrolytically detached, allowing retrieval even after full deployment. The stent is compatible with all currently available embolic agents and does not degrade MR images.

Abstract:

Most healthcare experts agree that there is a growing disparity between the availability of technology and society's ability to pay for it. Because consumerism in healthcare has become so intimidating to many practitioners, they are often compelled to provide the best, most highly advanced technologies available, regardless of their costs, to all patients. As one study notes, “technological advance is the dominant factor in the upward spiral in healthcare costs.” There is general agreement that some controls must be placed on our healthcare expenditures as evidenced by the call for “healthcare

Root resorption is largely pathologic and known to be initiated by several factors, including pulpal necrosis, trauma, periodontal treatment, orthodontic treatment, and bleaching agents.

The resorptive defect is often detected by the routine radiographic examination. A characteristic radiopaque line generally separates the image of the lesion from that of the root canal

Abstract:

Presented was the comparative characteristic of modern methods of diagnosing tissue viability in the diabetic foot syndrome with the assessment of their advantages and disadvantages. An analysis of articles was conducted devoted to diagnostic methods that are used in diabetic foot syndrome. Doppler ultrasound investigation of lower extremity arteries makes it possible to determine the level of trophic disturbances, the degree of stenosis, the type of blood flow, however the informativeness of the method decreases during distal forms of lesions, mismatch of indicators of regional ischemia and h

Abstract:

Aim. To investigate the prognostic value of serum N-terminal pro-brain natriuretic peptide (NT-proBNP) in the development of acute kidney injury (AKI) in patients with acute decompensated chronic heart failure (ADCHF). Subjects and methods. Eighty-three patients (55 (66%) men and 28 (34%) women; mean age, 65±11 years) with ADCHF were examined. AKI was diagnosed and classified according to the 2012 Kidney Disease Improving Global Outcomes Clinical Practice guidelines. To rule out contrast-induced AKI, the investigation enrolled only patients in whom radiopague agents had not been injected 7 day

Abstract:

Rigid bronchoscopy is a procedure that is performed in order to directly visualize the upper and lower airway, and is carried out for either a diagnostic or therapeutic purpose. Suspected foreign body (FB) aspiration is the most common indication for performing this procedure in the pediatric age group at the Philippine Children’s Medical Center where a recent census (May 2008 to April 2009) showed that of 21 cases where rigid bronchoscopy was performed, 10 were for suspected FB aspiration. A review of 101 cases in the same institution showed that the average age of patients with FB aspiration

Abstract:

AbstractAn important method used to make medical implants radiologically visible is based on introduction of radiopaque bromine or iodine containing methacrylic monomers. Thus, 2-(2-bromopropionyloxy) propyl methacrylate (BPPM) and 2-(2-bromoisobutyryloxy) propyl methacrylate (BIPM) were synthesized with the aim to use them as radiopaque agents. The free radical initiated copolymerization of BPPM and BIPM with methyl methacrylate (MMA) were performed directly in a thermostatic cell of the NMR spectrometer. The copolymer compositions obtained from 1H NMR spectra led to the determination of the

Abstract Objective This study was aimed to develop a method combining computed tomography (CT) and fluorescence imaging, allowing identification of microvasculature in anatomical donors and facilitating translational research and education. Methods We investigated homogeneity and radiopacity of 30 different mixtures including radiopaque substances povidone–iodine (Betadine), barium sulfate (BaSO4), and bismuth subsalicylate (Pepto-Bismol) varying in suspension and dilution with agar, latex, or gelatin. Three candidate mixtures were selected for testing the extent of perfusion in renal vasculat

Abstract:

Background: Prostacyclin and its stable analogues are vascular protective agents that have been used clinically to reduce blood vessel constriction. Recent studies indicate they stimulate angiogenesis in response to tissue ischemia, but their role in arteriolar growth remains unclear. In the current study, we test the hypothesis that the prostacyclin stable analogue carbaprostacyclin (cPGI2) facilitates arteriolar growth in ischemic hindlimbs. Methods and Results: Catheters were attached to osmotic pumps in order to continuously deliver either cPGI2 or saline (control) locally into ischemic mo
