Abstract Transparent sodium phosphate glass–ceramics system according to the composition (55- x ) P 2 O 5 .(30 + )ZnO.15Na where = 0, 2.5, 5, 7.5, and 10 was prepared with melt quenching technique. Different techniques such as XRD infrared spectroscopy (FTIR) were used investigate structure of studied glass samples nano composite. revealed formation crystalline phase. The phase Na Zn (P 7 ZnP .Zn has been detected which varies ZnO concentration. density increased whereas molar volume...
Being one of the most important tools in industrial and medical fields, red-NIR laser has caught a lot attention research studies to improve its emission efficiency stability lasing materials, both thermally mechanically. In this regard, intensity generated from Er3+ ions doped glass network was enhanced by adding Yb3+, Nd3+, Ce3+ ions. A host 44P2O5–15ZnO–10Pb3O4–15NaF–15MgF2–1Er2O3 proposed as material reinforced 0.5 1 mol% or (labeled PZPbNMEr3+:RE3+). The structural variations resulting...
Abstract A blue emitter of Er 3+ ions doped a host glass chemical composition 30B 2 O 3 –30Bi –20Li O–10BaO–10PbO was fabricated to be used in optoelectronics devices. Four proposed concentrations , which are 0.5, 1, 2, and 4 mol%, were suggested study the impact on structural, thermal, photoluminescence properties considered glass, respectively. The phase checking produced glasses using X-ray diffraction patterns showed amorphicity formation. Impact structural network extensively studied...
Background The diagnosis of sonographically indeterminate adnexal masses (AM) signifies a major challenge in clinical practice. Early detection and characterization have increased the need for accurate imaging evaluation before treatment. Purpose To assess validity reproducibility ADNEX MR Scoring system AM. Study Type A prospective multicenter study. Population In all, 531 women (mean age, 44 ± 11.2 years; range, 21–79 years) with 572 Field Strength/Sequence 1.5T /precontrast T 1 ‐weighted...
Abstract Background The inflatable penile prosthesis (IPP) is typically the preferred implant for Peyronie’s disease (PD) and malleable prostheses (MPPs) have been discouraged. Aims To evaluate effectiveness patient satisfaction of MPP vs IPP in patients with PD. Methods Men PD erectile dysfunction who elected surgery constituted study population. Preoperatively, demographic comorbidity parameters were recorded. Curvature was measured a goniometer at maximum rigidity after intracavernosal...
Gliomas are a type of brain tumor that requires accurate monitoring for progression following surgery. The Brain Tumor Reporting and Data System (BT-RADS) has emerged as potential tool improving diagnostic accuracy reducing the need repeated operations. This prospective multicenter study aimed to evaluate reliability BT-RADS in predicting (TP) postoperative glioma patients its acceptance clinical practice. enrolled with history partial or complete resection high-grade glioma. All underwent...
White light emitters remain in the need of continual development and research for new materials. In this context, a low phonon energy glass containing Er3+ ions was prepared using conventional melt/casting technique. The chemical compositions synthesized materials were analyzed X-Ray Fluorescence (XRF) measurements. Diffraction (XRD) pattern strongly affirms non-crystalline essence produced behavior both density Fourier Transform Infrared (FTIR) spectroscopy denoted that have modifier role...
Intracorporeal injections (ICIs) of vasoactive substances during penile Doppler ultrasound (PDU) are a common investigation for erectile dysfunction (ED) diagnosis. ICI can be responsible priapism, pathological condition prolonged erection not related to sexual stimulation. The aim our study is investigate the effectiveness physical exercise and medical treatment as noninvasive therapy restore detumescence in erections after ICI.Data were prospectively collected on men undergoing PDU three...
Effect of Co and Mo ions on the sodium zinc borophosphate glasses network was investigated. Both structural optical properties were studied by Xray diffraction, density, Infrared spectroscopy absorption. Only a broad halo is observed in X-ray diffraction patterns indicating non-crystalline nature prepared samples. Density related parameters such as molar volume average boron-boron separation showed that glass became more compact increasing oxide. Fourier Transform (FTIR) results free -...

Four grades of gadolinium doped lead borosilicate glasses were prepared using the normal melt-quenching process as well a free sample. The structural changes induced by Gd3+ ions content in network examined FTIR and density. analysis measurements indicates that Gd2O3, evidently, has an obvious effect on glass network. Analysis optical data reveals compositional dependence band gap Urbach energy. Variation these parameters been associated with occurring increase content. values considered...
Reported cases encountered difficulty in differentiating between inflammatory carcinoma and breast edema caused by congestive heart failure especially if the is unilateral. Our presented case an elderly woman with unilateral due to that was initially suspected have cancer based on clinical findings. However imaging studies showed pattern no definite underlying mass. This resolved standard treatment of failure. Congestive may be a possible cause patient background
Introduction Iliac aneurysms occur in 10% of patients with abdominal aortic (AAA). There are three different endovascular approaches to their treatment the context infrarenal Endovascular Aortic Aneurysm Repair (EVAR): occlusion by coiling internal iliac, incorporation using an iliac branch device, and delaying repair a bell bottom limb. We sought determine outcomes associated these strategies our practice. Methodology The study was combined prospective cohort retrospective arm: patient...
