Background:
Bursitis is a chronic inflammatory condition characterized by the deposition of cholesterol, macrophage infiltration, and bursal wall calcification. Bursitis is, however, rarely found in the sacrococcygeal region where it may present as a space-occupying mass.

Case Description:
A 64-year-old male with rheumatoid arthritis presented with 3 years’ duration of difficulty sitting and walking due to a soft-tissue mass involving the coccyx region. Once the patient’s MR demonstrated a cystic lesion with erosion of the coccyx, the patient underwent gross total resection of the lesion that proved to be pathologically consistent with bursitis. Postoperatively, the patient’s complaints fully resolved.

Conclusion:
Bursitis may present as a soft-tissue tumor-like lesion in the coccyx that favorably responds to gross total surgical excision.

Published: May 2021

Interactive molecular dynamics in virtual reality (IMD-VR) simulations provide a digital molecular playground for students as an alternative or complement to traditional molecular modelling kits or 2D illustrations. Previous IMD-VR studies have used molecular mechanics to enable simulations of macromolecules such as proteins and nanostructures for theclassroom setting with considerable success. Here, we present the INTERACHEM molecular visualizer, intended for reactive IMD-VR simulation using semiempirical and ab initio methods.INTERACHEM visualizes not only the molecular geometry, but also 1) isosurfaces such as molecular orbitals and electrostatic potentials, and 2) two-dimensional graphs of time-varyingsimulation quantities such as kinetic/potential energy, internal coordinates, and user-applied force. Additionally, INTERACHEM employs speech recognition to facilitate user interaction and introduces a novel “atom happiness” visualization using emojis to indicate the energeticfeasibility of a particular bonding arrangement. We include a set of accompanying exercises that we have used to teach chemical reactivity in small molecular systems.

Authors: Pektaş Gökhan , Kırlı İsmail 
Published: May 2021

Objective: This study aims to clarify the effects of intravenous iron supplementation on biomarkers for oxidative stress in women with iron deficiency anemia.
Methods: This is a cross-sectional review of 40 healthy women and 40 women who underwent intravenous iron treatment due to anemia. Biochemical markers for oxidative stress were determined for both healthy controls and anemic patients. These markers were also evaluated at hour 1 and day 30 of intravenous iron treatment.
Results: The patients with anemia had significantly higher catalase activity and total oxidant status (TOS) but significantly lower nitrate and total anti-oxidant status (TAS) than the healthy controls (p=0.0245, p<0.0001, p=0.0437 and p<0.0001 respectively). At hour 1 of intravenous iron treatment, nitrate, nitrite, nitric oxide, total thiol and TAS values were significantly lower and TOS values were significantly higher than those before the administration of treatment (p=0.0322, p=0.0003, p=0.0005, p<0.0001, p<0.0001 and p=0.004). At day 30 of intravenous iron treatment, catalase activity, nitrate, total thiol and TOS values were significantly lower than those before the administration of treatment (p=0.0332, p=0.0015, p=0.0391 and p<0.0001 respectively) and at hour 1 of treatment (p=0.0498, p<0.0001, p=0.0004 and p<0.0001 respectively). At day 30 of intravenous iron treatment, nitric oxide and TAS values were significantly higher than those before the administration of treatment (p=0.0480 and p=0.001 respectively) and at hour 1 of treatment (p<0.0001 for both).
Conclusion: Intravenous iron replacement prompts oxidative stress at hour 1 of infusion in adults with anemia but this increase resolves partially in the following 30 days.

OPTICAL COHERENCE TOMOGRAPHY-ANGIOGRAPHY, A NEW DIAGNOSTIC AND FOLLOW-UP TOOL FOR GLAUCOMA
Authors: İnan Sibel , İnan Ümit Übeyt 
Published: May 2021

Glaucoma is an optic neuropathy and is one of the leading causes of irreversible blindness worldwide. There are studies on the role of vascular dysfunction in the pathogenesis of glaucoma. Evaluation of intraocular blood flow will be useful in elucidating the pathogenesis. Various techniques are available for the diagnosis and follow-up of patients with glaucoma. Optical coherence tomography angiography (OCTA) has emerged as new technology to detect the vascular effects of glaucoma.
Objectives: Optical coherence tomography angiography is a new technology and many publications have been made in the field of glaucoma. In this article, we aimed to review the studies conducted on the role of OCTA technology in glaucoma pathogenesis and to draw attention to how OCTA can be helpful for diagnosis and follow-up in glaucoma patients.
Methods: Whole literature through PubMed for the keywords of optical coherence tomography angiography (OCTA) and glaucoma were scanned. This review included articles up to February 2021. Only English languages articles were included.
Results: Optical coherence tomography angiography provides a rapid and noninvasive quantitative assessment of the microcirculation of the retina, optic nerve, and choroid. Optical coherence tomography angiography uses the action of red blood cells as an intrinsic contrast agent. It has high reproducibility. Optical coherence tomography angiography studies have shown that microcirculation in the superficial optic nerve, peripapillary retina, and the macula is reduced in glaucoma patients. Optical coherence tomography angiography parameters in the peripapillary region are thought to be better biomarkers in advanced glaucoma than OCT parameters.
Conclusion: Optical coherence tomography angiography is a new technology that has the potential to provide useful information in the diagnosis and follow-up of patients with glaucoma.

Published: May 2021

The aim of this study was to investigate the extraction method for R. tomentosa and C. zeylanicum leaves and the evaluation of antibacterial and antioxidant activities of crude extracts. The results of the study showed that the active ingredients of crude extracts were clearly separated by Thin-layer chromatography and the presence of rhodomyrtone in R. tomentosa crude extract and cinnamaldehyde in C. zeylanicum crude extract. R. tomentosa crude extract was antibacterial activity against Staphylococcus aureus with 13.1 mm of inhibition zone, but is not effective against Salmonella Typhimurium. C. zeylanicum leaf extract did not show antibacterial activity on both S. aureus and S. Typhimurium. At a dilution of 1/2 of the R. tomentosa crude extract can completely inhibit S. aureus growth. This study also indicated the presence of antioxidant compounds such as flavonoids, tannins, phenols and terpenoids in C. zeylanicum and R. tomentosa crude extracts. The results showed that R. tomentosa and C. zeylanicum crude extracts should be used as a biotherapy alternative to antibiotic therapy. However, further study would be needed to investigate the antibacterial activity of crude extracts in vivo.

Characterization of Erosion Resistant Cr3C2-NiCr Plasma Sprayed Coatings
Authors: Kim D.-Y. , Han M.-S. , Youn J.-G. 
Published: May 2021

Abstract
Properties of an erosion resistant Cr3C2 - NiCr coating have been studied as a function of both plasma spraying process variables and heat treatment. The as-sprayed Cr3C2 - NiCr coating revealed low hardness value of 380-470 Hv, which provided the coating with a poor erosion resistance. This is directly attributed to the decomposition of Cr3C2 constituent into Cr7C3 and graphite phases during the spraying. It was not the effective way to control the process variables such as arc current and stand-off distance for preventing the decomposition of Cr3C2 constituent. A proper heat treatment on the as-sprayed coating increases the hardness of the coating in a great extent up to 900Hv so that the erosion resistance of the coating is clearly improved. This was confirmed to be attributed to the recovery of Cr3C2 at the expense of graphite phase and the formation of Cr2O3 by the heat treatment. In addition, the formation of Cr2O3 phase plays an important role of increasing the erosion resistance of the coating by healing the microcracks of the as-sprayed coating. These are the microstructural features responsible for the high erosion resistance of the coating after a proper heat treatment.

Use of Combined Plasma Cleaning/Coating Process for the Cathodic Protection of Reinforced Concrete Structures
Authors: Finkelshteyn A. , Bimman A.L. 
Published: May 2021

Abstract
Considering the number of concrete structures such as bridges, overpasses, trestles etc., their maintenance and repair form a significant part of the highway administration budget. Cathodic protection is becoming more popular because it helps reduce maintenance and renovation costs. Arc-sprayed zinc and zinc/aluminum alloy coatings are widely used in cathodic protection systems. The surface preparation of concrete is critical to the quality of coating and hence, the quality of the cathodic protection. Typically, sandblasting with surface brushing is used as preparation. This method has several technical, economic and ecological deficiencies: weather/humidity limitations, difficult removal of organic contaminants from the surface, an irrevocable loss of blasting media, high dust level, etc. An objective of this proceeding is to describe a plasma cleaning process as a successful alternative to sandblasting and to show the possibilities of combined plasma cleaning/coating process for the cathodic protection of reinforced concrete structures. This environmentally friendly process will result in better anodic coatings at lower cost and fewer concrete structure repairs.
