Pulsed TIG Cladding of a Highly Carbon-, Chromium-, Molybdenum-, Niobium-, Tungsten- and Vanadium-Alloyed Flux-Cored Wire Electrode on Duplex Stainless Steel X2CrNiMoN 22-5-3.

The hardfacing process aims to increase the life span of structural components in the petrochemical, mining, nuclear and automotive industries. During operation, these components are subject to demands of abrasion wear, cavitation erosion and corrosion. Duplex stainless steels are characterized by high mechanical characteristics and corrosion resistance, but poor behavior to abrasive wear and cavitation erosion.

The Impact of Intraocular Treatment on Visual Acuity of Patients Diagnosed with Branch Retinal Vein Occlusions.

Branch retinal vein occlusions are a significant cause of vision loss and present several ophthalmic and systemic risk factors, including age, hypertension, hyperlipidemia and glaucoma. Retinal vein occlusion is the second-most-common retinal vascular disease. This study evaluated the effects of Ozurdex in contrast to a combination therapy with anti-vascular endothelial growth factor (VEGF) and cortisone in treatment-naive branch retinal vein occlusions-macular edema (BRVO-ME) cases, at 4-month and 6-month follow-ups.

Corneal endothelial changes induced by pars plana vitrectomy with silicone oil tamponade for retinal detachment.

Silicone oils are effective intraocular tamponade agents in the treatment of severe retinal detachments, because they maintain the adhesion between neurosensory retina and retinal pigment epithelium, thanks to their ability to remove aqueous humor from the surface of the retina. To understand their effectiveness, it is important to know the characteristics of silicone oils. Patients should be closely monitored due to many complications associated with intraocular silicon oil, such as inflammatory reaction, raised intraocular pressure, refraction disorders, cataract, and emulsification.

Endothelial corneal cell damage after pars plana vitrectomy: analogy of different intraocular tamponade agents.

A reduction in the corneal endothelial cells multitude after anterior pole intervention is well established in numerous researches, but there are few articles that follow the impact of vitreoretinal interventions on the cornea, especially when endotamponade agents are used. The assessment of the endothelial corneal cells is needed since it facilitates the personal evaluation of the functional endothelial stock. Specular microscopy investigation offers a scale of the functional strength of the endothelium of cornea, which is vital before all intraocular interventions.

Internal Hexagon vs Conical Implant-Abutment Connections: Evaluation of 3-Year Postloading Outcomes.

Different types of internal implant-abutment connections, namely hexagon and conical, have been used for implant restoration. However, data regarding the benefits of these internal connections in terms of clinical outcomes are scarce. Accordingly, the aim of this study was to compare radiographic marginal bone loss (RMBL) and associated implant complications between implants with internal hexagon (IH) connections and those with internal conical (IC) connections.

Triamcinolone acetonide induces sterile endophthalmitis in patients with intermediate uveitis: A case report series.

Due to their anti-inflammatory, antiangiogenic and antiedematous properties, corticosteroids have been commonly used in the treatment of retinal diseases. Intravitreal administration of steroids offers the maximal drug efficacy and the lowest risk of systemic side effects. The authors report three cases of presumed sterile endophthalmitis induced by triamcinolone acetonide (TA) in three eyes with intermediate non-infectious uveitis.

Clinical outcomes of micropulse transscleral cyclophotocoagulation in refractory glaucoma-18 months follow-up.

The aim of this study is to evaluate the clinical outcomes of micropulse transscleral cyclophotocoagulation (mTSCPC) in cases of refractory glaucoma. Patients with refractory glaucoma were selected to undergo mTSCPC, using the MP3 handpiece from Iridex Laser Systems. Follow-up examinations occurred on a regular basis for 18 months after the procedure.

Implant survival rate and marginal bone loss of 6-mm short implants: a 2-year clinical report.

Purpose: This study aimed to evaluate (1) the association between implant diameter and marginal bone loss (MBL) of short (6 mm) implants and (2) the survival rates of short implants.

Materials And Methods: Thirty-three 6-mm implants were placed in the mandibles of 16 qualified patients. The selected sites had > 5 mm ridge width and < 9 mm bone height.
