Dental trauma is such a situation wherein the patient is affected both socially and psychologically. During their first dental visit, these patients with trauma are in pain and need emergency treatment. Such patients are quite apprehensive because of impaired functions, esthetics, and phonetics. The prime objective while handling such cases is successful pain management with immediate restorati...

The current empirical study was conducted to investigate the wall neighborhood impact on the two-dimensional flow structure and heat transfer enhancement behind a square cylinder. The low- velocity open-circle wind tunnel was used to carry out the study tests considering the cylinder diameter (D)-based Reynolds number (ReD) of 5130. The selected items to compare were different gap he...

This paper investigates the flow characteristics along a ribbed square duct using time-resolved particle image velocimetry. The Reynolds number, defined by main velocity (1.82 m/s) and hydraulic diameter (80 mm), is 10 000. rotation numbers are 0, 0.13, 0.26, 0.39, 0.52. blockage aspect ratios of 0.1 1, respectively. As number increases, recirculation zone on suction side becomes larger, reatta...

SUMMARY A successful bilateral ear composite graft nonmicrosurgical reattachment is presented. In cases where suitable vessels are unavailable for microsurgical revascularization, the reconstructive challenge can be formidable for salvaging the unique anatomic and aesthetic structure of the ear. The case is presented of an 18-year-old woman who was a victim of an assault wherein both of her ear...

INTRODUCTION Densiron(®) 68 is a high-density liquid used to tamponade inferior retinal detachments. We present a case series of 12 patients treated with Densiron as an intraocular tamponade agent. METHODS A retrospective analysis of 12 eyes in 12 patients was carried out. The primary endpoint was anatomic reattachment of the retina following removal of Densiron oil. RESULTS All patients ha...

PURPOSE To identify changes in S- and M-sensitive cone opsin gene expression following retinal detachment (RD) and reattachment. METHODS Cat retinas were detached for 1, 3, 7, or 28 days, or reattached after 1 h, 1 day, or 3 days of RD and fixed in 4% paraformaldehyde. Pieces of mid-peripheral retina were removed from the same region of each detached, normal (attached), and reattached retina ...

Retinal detachment, the separation of the neural retina from the retinal pigmented epithelium, starts a cascade of events that results in cellular changes throughout the retina. While the degeneration of the light sensitive photoreceptor outer segments is clearly an important event, there are many other cellular changes that have the potential to significantly effect the return of vision after ...

PURPOSE To determine the effects of reattachment on the molecular and cellular events initiated by a retinal detachment lasting 1 hour or 1 day. METHODS Experimental retinal detachments were created in the right eyes of nine cats. Reattachments were performed 1 hour (n = 3) or 1 day (n = 3) after the detachment, and the animals were killed 3 days after detachment. Three-day detached (n = 3) a...

In the present case reports, it was aimed to present the treatment of 2 non-complicated crown fracture trauma cases using reattachment technique. In the first case 12-years-old patient was applied to our clinic due to crown fracture. In the clinic examination the tooth’s mobility was within the normal limits and tooth was not tender to percussion. There was also cold-sensitivity due to the expo...
