AIM The aim of this report is to present a case of Type III dens invaginatus in a maxillary lateral incisor with a periapical lesion and its successful treatment using a combination of surgical and non-surgical therapy. BACKGROUND The morphology of the root canal system is unique for individual teeth. A precise understanding of the morphology is very important for a successful root canal trea...

A 78-year-old woman presenting with fever and occipital headache was referred to our service with suspicion of meningitis. Neurological examination was normal except for cervical stiffness. CRP level was increased to 18.7 mg/dl. Cerebrospinal fluid examination was normal. Cervical CT image at C1/C2 level showed right dominant semicircular calcifications posterolateral to the odontoid process (d...

In this paper we report the electrochemical synthesis of core@shell dendrimer-encapsulated nanoparticles (DENs) consisting of cores containing 147 Au atoms (Au147) and Pt shells having!54 or !102 atoms (Au147@Ptn (n1⁄4 54 or 102)). The significance of this work arises from the correlation of the experimentally determined structural and electrocatalytic properties of these particles with density...

PURPOSE To evaluate the change of axial length (AL), intraocular pressure (IOP), and corneal astigmatism after scleral shortening with scleral invagination in the rabbit eye. METHODS The authors performed scleral shortening (3 mm) with scleral invagination in two groups of 6 eyes each: 180 degrees (group 1) and 360 degrees (group 2). RESULTS Average AL shortening was more prominent in group...

High-resolution solution (1)H NMR spectroscopy has been used to characterize the size of Pd dendrimer-encapsulated nanoparticles (DENs). The Pd nanoparticles measured by this technique contain 55, 147, 200, or 250 atoms, and they are encapsulated within sixth-generation, hydroxyl-terminated poly(amidoamine) PAMAM dendrimers (G6-OH). Detailed analysis of the NMR data shows that signals arising f...

In this paper, we extend two classical results about the density of subgraphs of hypercubes to subgraphs G of Cartesian products G1 × · · · × Gm of arbitrary connected graphs. Namely, we show that |E(G)| |V (G)| ≤ d2 max{dens(G1), . . . , dens(Gm)}e log |V (G)|, where dens(H) is the maximum ratio |E(H′)| |V (H′)| over all subgraphs H ′ of H. We introduce the notions of VC-dimension VC-dim(G) an...

Dendritic ecological networks (DENs) are a unique form of ecological networks that exhibit a dendritic network topology (e.g. stream and cave networks or plant architecture). DENs have a dual spatial representation; as points within the network and as points in geographical space. Consequently, some analytical methods used to quantify relationships in other types of ecological networks, or in 2...

BACKGROUND Partial thickness sclerectomy is the most commonly employed scleral shortening technique used in conjunction with pars plana vitrectomy in the repair of myopia-associated macular holes in patients with staphyloma. Recently, scleral shortening induced through scleral invagination has been advocated as an adjunct in retinal translocation surgery. OBJECTIVE To determine whether a corr...

PURPOSE OF THE STUDY Surgical treatment is preferred in our department in all patients with type II and type III dens fractures, regardless of their age, with the exception of non-displaced or completely reduced fractures in young patients. The aim of this study was to evaluate patients over 65 years of age treated by direct osteosynthesis of the dens or posterior atlanto-axial fixation and spo...
