Clinical validity of fluorescence-based devices versus visual-tactile method in detection of secondary caries around resin composite restorations: diagnostic accuracy study.

Objectives: To assess the validity of light-induced and laser-induced fluorescence devices compared to the visual-tactile method for detecting secondary caries around resin composite restorations.

Materials And Methods: The study included 20 participants with 30 resin-composite restored teeth. Restorations' margins were examined using three diagnostic methods: the visual-tactile method (FDI criteria), the light-induced fluorescence camera (VistaCam iX), and the laser-induced fluorescence device (DIAGNOdent pen), and the reference was visual inspection after removal of defective restorations.

New local magnitude scales for Egypt.

Local magnitude (M) scales have been developed for Egypt based on 14,453 normalized Wood-Anderson amplitudes from 1670 earthquakes. These events were recorded by at least four seismic stations, with hypocentral depths of less than 40 km and earthquake magnitudes ranging from 0.1 to 6.

Screening and Impact of Neuropathic Pain in Young Individuals With Sickle Cell Disease.

Objective: To assess the frequency of neuropathic pain (NP) and its impact in young patients with sickle cell disease (SCD).

Methods: We used the ID-Pain (ID-P) questionnaire and a bedside clinical sensory testing (CST) as screening tools for NP and performed sensory nerve conduction study (SNCS) for all the participants. The impact of pain was assessed using Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaires and Pediatric Quality of Life Inventory (PedsQL) SCD module.

SARS-CoV-2 evolution balances conflicting roles of N protein phosphorylation.

All lineages of SARS-CoV-2, the coronavirus responsible for the COVID-19 pandemic, contain mutations between amino acids 199 and 205 in the nucleocapsid (N) protein that are associated with increased infectivity. The effects of these mutations have been difficult to determine because N protein contributes to both viral replication and viral particle assembly during infection. Here, we used single-cycle infection and virus-like particle assays to show that N protein phosphorylation has opposing effects on viral assembly and genome replication.

A novel method to assess photobiomodulation in stimulating regenerative capacity and vascularization in zebrafish.

Photobiomodulation (PBM) therapy is a continuously growing approach to stimulating healing and reducing inflammation and pain. However, its effects in the fields of regenerative medicine and tissue engineering are still under investigation. Studying PBM effects on the regenerative capacity of zebrafish can allow the application of novel clinical approaches where the impact of PBM will be cross-linked with the stem-cell therapeutic approaches.
