Purpose: This study investigates the capabilities of ultrasonography (US) in determing the stage of orbital inflammation in patients with granulomatosis with polyangiitis (GPA).
Material And Methods: The study included 24 patients (8 men and 16 women) with diffuse orbital tissue involvement in GPA. Group 1 (active stage) included nine patients, while group 2 (inactive stage) consisted of 18 patients. Three patients were in both groups. In four patients (16.7%), the inflammation was bilateral, while the remaining 20 (83.3%) had unilateral orbital involvement. A total of 13 US examinations were conducted in group 1, and 22 in group 2. All patients underwent orbital US, including duplex scanning of ocular and orbital vessels, along with multiplanar combined spatial analysis of the orbital inflammatory mass.
Results: The ultrasound characteristics in orbital GPA, specifically acoustic density, presence of pathological blood flow within and around the inflammatory mass, and flow intensity varied according to the stage of the inflammatory process.
Conclusion: Ultrasound is a non-invasive and accessible method for assessing inflammation activity in orbital GPA.

Objective: The production of 3-dimensional models and materials according to preoperative virtual surgical planning is a time-consuming process and causes high costs. We aimed to demonstrate the navigation mediated reconstruction of the patients who underwent the removal of a tumoral mass in midfacial region according to their preoperatively prepared surgical plannings.
Study Design: Patients who underwent the removal of tumoral mass and reconstruction in their midfacial region were included in the study.

The ruthenium compounds have been known to have the wide range of potential applications as anticancer, antibacterial and anti-diabetic etc. The ligand substitutions play a vital role in enhancing the pharmacological and biological activities. In the present study, three ruthenium-metal based complexes, designated as (I-III), were synthesized and characterized employing element analysis, FTIR and HNMR.

A 66-year-old woman presents with unilateral orbital inflammation of several years of evolution, initially classified as idiopathic orbital inflammatory disease (IOID) subtype myositis. She presented with pain, eyelid inflammation and significant elevation of intraocular pressure, as well as radiological signs of exophthalmos and superior rectus myositis. She was treated with corticosteroids, with partial response.

Lithium-sulfur batteries (LSBs) offer high energy density and environmental benefits hampered by the shuttle effect related to sluggish redox reactions of long-chain lithium polysulfides (LiPSs). However, the fashion modification of the d-band center in separators is still ineffective, wherein the mechanism understanding always relies on theoretical calculations. This study visibly probed the evolution of the Co 3d-band center during charge and discharge using advanced inverse photoemission spectroscopy/ultraviolet photoemission spectroscopy (IPES/UPS), which offers reliable evidence and are consistent well with theoretical calculations.
