The ubiquitous m7G cap of eukaryotic mRNAs and of precursors to the spliceosomal small nuclear RNAs (snRNAs) is the result of an essential RNA modification acquired during transcript elongation. In trypanosomes, the m7G cap is restricted to the spliced leader (SL) RNA and the precursors of U2, U3, and U4 snRNAs. mRNA capping in these organisms occurs posttranscriptionally by trans splicing, whi...

Thin films of topological insulators are often capped with an insulating layer since topological insulators are known to be fragile to degradation. However, capping can hinder the observation of novel transport properties of the surface states. To understand the influence of capping on the surface states, it is crucial to understand the crystal structure and the atomic arrangement at the interf...

diabetes mellitus is a chronic disease which affects the healing ability of the pulp and periodontium. the aim of the present study was to assess the histopathologic response of dental pulp to pulp capping using mta or cem cement in diabetic rats. thirty two wistar male rats aged between 8 and 10 weeks (weight: 200-250g) were divided into two groups of diabetic (n=16) and healthy (n=16) animals...

statement of problem: recently, it has been proposed that different adhesive materials can be used for direct pulp capping. previous studies have demonstrated that multi steps dentin adhesives could form reparative dentin similar to calcium hydroxide (ch). purpose: the aim of this study was to evaluate the histological pulp response of ninety mechanically exposed cat pulps to two adhesive resin...

introduction: direct pulp capping (dpc) is coverage of exposed pulp by a biocompatible material after traumatic or carious exposure. the purpose of this procedure is to seal against bacterial leakage, stimulate dentinal barrier formation, and maintain the vitality of pulp. several factors contribute to the consequence of this treatment such as material and the procedural technique. the aim of t...

BACKGROUND Talon cusp is a supernumerary structure projecting from the dento-enamel junction to a variable distance towards the incisal edge of an anterior tooth. Studies have shown that it consists of enamel, dentine and a variable amount of pulp tissue. Hyperactivity of the enamel organ during morphodifferentiation has been attributed to its formation. Most previous reports have been made con...

Fusion and talon cusps are rare developmental dental anomalies affecting both primary and permanent dentitions. Talon cusps normally occur on the palatal surface of permanent maxillary incisors, while fused teeth are more common in the primary anterior dentition. An understanding of these dental anomalies and their associated problems are important to provide prophylactic measures, thereby prev...

Incorporating a one-dimensional (1D) perovskite capping layer on top of absorber, improves the stability solar cells (PSCs). Dissimilarity matrices gives an comparison overview across capping-absorber pairs.

Purpose: Morphological dental anomalies of the maxillary lateral incisors are relatively common. However, their simultaneous occurrence is a relatively rare event. We report a case of dens invaginatus and talon cusp concurrently affecting maxillary lateral incisors. The etiology, pathophysiology, association with other dental anomalies, as well as various treatment modalities of these anomalies...
