Perforating Internal Root Resorption Sealed with Single-Cone Technique Using Bioceramic Sealer: A Case Report.

Am J Case Rep

January 2025

Department of Restorative Dentistry, College of Dentistry, Umm Al-Qura University, Mekkah, Saudi Arabia.

BACKGROUND Internal root resorption (IRR) is a rare dental condition characterized by the progressive resorption of dentin within the root canal, often resulting from infection, trauma, or orthodontic treatment. When IRR progresses to perforation, it creates a communication pathway with periodontal tissues, necessitating effective endodontic therapy and perforation repair. Bioceramic sealers, known for their biocompatibility and flowability, have emerged as a promising alternative to traditional materials for filling and sealing the root canal system.

This study develops an Artificial Neural Network (ANN)-based framework to model the transmission dynamics and long-term disability outcomes of Ebola Virus Disease (EVD). Building on existing deterministic SEIR models, we extend the framework by introducing a disability compartment, capturing the progression of Ebola survivors to chronic health complications, such as post-Ebola syndrome. The proposed model stratifies the population into various epidemiological states, incorporating delays to better reflect the natural progression and intervention strategies associated with EVD.

Aim: New phenyldiazene scaffold-linked heterocyclic pyrazole, pyrimidinone, pyrimidinthione, and/or triazine rings have been developed and synthesized.

Methods & Results: Cytotoxicity of our derivatives was estimated on four cancer and VERO normal cell lines targeting EGFR (epidermal growth factor receptor) and VEGFR-2 (vascular endothelial growth factor receptor-2) enzymes. Our new derivatives selectively inhibited both VEGFR-2 and EGFR as they have the essential structural requirements for inhibitors of both receptors.

To concentrate omega-3 fatty acids (-3) in fish oil (FO), olein and super olein fraction (OF) of FO were produced by winterization. For this purpose, FO was slowly cooled to -50°C (24 h), the mixture of crystallized and non-crystallized phases was separated, filtrate was coded as OF (yield 32%), 35% of OF was kept for storage study and analytical purpose, remaining 65% was further slowly cooled down to -75°C (24 h) and filtered, filtrate was coded as super olein (SF, yield 23%). GC-MS analysis showed that unsaturated fatty acids increased due to successive winterization.

Background: Ecthyma is a deeper form of impetigo involving the epidermis and dermis causing ulcerative plaques. Pathogens commonly responsible for the disease (group A beta-hemolytic streptococcus and Staphylococcus aureus) typically afflicts children, presenting during early stages with skin lesions that can closely resemble other vesicular and ulcerative dermatoses, such as those observed in mpox infection. The ongoing global outbreak of monkeypox has escalated the urgency for clinicians to accurately differentiate between these conditions due to their overlapping dermatological manifestations.

MXene-based multilayered and ultrawideband absorber for solar cell and photovoltaic applications.

Sci Rep

January 2025

Department of Information Technology, College of Computers and Information Technology, Taif University, P.O. Box 11099, Taif, 21944, Saudi Arabia.

We proposed the ultrawideband solar absorber using the multisized metal resonator oriented on the top of the multilayered Metal-SiO₂-MXene-MgF₂-Tungsten structure. We have carried out a numerical investigation of this structure for the 100-2500 THz frequency, which covers the infrared, visible, and UV spectra. The proposed solar absorber is numerically investigated for the different physical parameters, such as the height of the layers, unit cell size, and resonator orientation, to identify optimized results for the high absorption capacity.
