Anti-herpetic tau preserves neurons via the cGAS-STING-TBK1 pathway in Alzheimer's disease.

Alzheimer's disease (AD) diagnosis relies on the presence of extracellular β-amyloid (Aβ) and intracellular hyperphosphorylated tau (p-tau). Emerging evidence suggests a potential link between AD pathologies and infectious agents, with herpes simplex virus 1 (HSV-1) being a leading candidate. Our investigation, using metagenomics, mass spectrometry, western blotting, and decrowding expansion pathology, detects HSV-1-associated proteins in human brain samples.

The development of murine bone marrow-derived mast cells expressing functional human MRGPRX2 for and studies.

Introduction: A subtype of human mast cells (MCs) found in the skin and to a lesser extent in the lung and gut express a novel G protein-coupled receptor (GPCR) known as Mas-related GPCR-X2 (MRGPRX2, mouse counterpart MrgprB2). In addition to drug-induced pseudoallergy and cutaneous disorders, MrgprB2 contributes to ulcerative colitis, IgE-mediated lung inflammation and systemic anaphylaxis. Interestingly, most agonists activate MRGPRX2 with higher potency than MrgprB2.

Evaluation of mandibular and maxillary second molar root canal anatomy in a Turkish subpopulation using CBCT: comparison of Briseno-Marroquin and Vertucci classifications.

Background: This retrospective study aims to characterise the root canal morphology of maxillary and mandibular second molars using cone-beam computed tomography (CBCT). The number of roots and canal configurations were evaluated using both the Vertucci and Benjamı´n Brisen˜ o Marroquı´n classification systems.

Methods: A total of 1084 second molar images (523 maxillary; 266 right and 257 left side and 561 mandibular; 285 right and 276 left side) were evaluated from 320 CBCT scans analyzed for the Turkish subpopulation.

Functional assessment of cancer therapy - head & neck (FACT-HN) translation and validation in Serbian.

This study aimed to translate and validate the Functional Assessment of Cancer Therapy - Head & Neck (FACT-HN) in a Serbian-speaking population, assessing its psychometric properties and utility in evaluating the quality of life in head and neck cancer patients. The research focuses on determining the translated questionnaire's reliability, validity, and cultural relevance. A total of 106 Serbian-speaking head and neck cancer patients completed the translated FACT-HN, along with other validated instruments, including the EORTC QLQ-C30, EORTC QLQ-HN43, CES-D, and GAD-7.

Modified Approach to Segmental Maxillary Surgery: Midline Osteotomy and Parasagittal Soft Tissue Incisions.

Traditional surgical techniques for segmental maxillary surgery include a combination of interdental osteotomies with paramidline bony cuts while keeping the palatal soft tissue intact. Besides surgical complexity, segmental maxillary procedures have been associated with higher incidence of relapse and complications. We present our experience with specific hard- and soft-tissue modifications (midline bony osteotomy and reflection of palatal soft tissue with carefully designed incisions) which will allow surgeons to perform larger expansions with a low incidence of complications and decreased relapse.

Parent-Targeted Oral Health Text Messaging for Underserved Children Attending Pediatric Clinics: A Randomized Clinical Trial.

Importance: Caries is the most common chronic childhood disease, with substantial health disparities.

Objective: To test whether parent-targeted oral health text (OHT) messages outperform child wellness text (CWT) messages on pediatric caries increment and oral health behaviors among underserved children attending pediatric well-child visits.

Design, Setting, And Participants: The parallel randomized clinical trial, Interactive Parent-Targeted Text Messaging in Pediatric Clinics to Reduce Caries Among Urban Children (iSmile), included participants who were recruited during pediatric medical clinic visits at 4 sites in Boston, Massachusetts, that serve low-income and racially and ethnically diverse (herein, underserved) populations.

Effects of epigallocatechin gallate on the development of matrix-rich biofilm.

In this study, we evaluated the impact of Epigalocatechin-3-gallate (EGCG) on biofilm development for 24 and 46 h using high-resolution confocal laser scanning microscopy. EGCG treatment led to the formation of interspaced exopolysaccharide (EPS)-microcolony complexes unevenly distributed on the surface of hydroxyapatite disc, forming a thinner and less complex biofilm structure with significantly reduced biomass, matrix volume, and thickness compared to the NaCl treated group (negative control). At 46 h, the biofilm of the EGCG-treatment group failed to form the bacterial-EPS superstructures which is characteristic of the biofilm in the negative control group.

Expression of beam hardening artifacts on horizontally stitched cone-beam computed tomography images.

Purpose: This study was performed to evaluate the expression of beam hardening artifacts generated by high atomic number materials in stitched cone-beam computed tomography (CBCT) images, compared to the traditional acquisition mode.

Materials And Methods: CBCT volumes were acquired using an acrylic resin phantom embedded with pairs of cylinders made from amalgam dental alloy, cobalt-chromium alloy, gutta-percha, titanium, and zirconium. These cylinders were placed within the overlapping zones of the stitching reconstruction area.

Clinical evaluation of the accuracy of two face scanners with different scanning technologies.

Multiarm-Assisted Design of Dendron-like Degradable Ionizable Lipids Facilitates Systemic mRNA Delivery to the Spleen.

Lipid nanoparticles (LNPs) have emerged as pivotal vehicles for messenger RNA (mRNA) delivery to hepatocytes upon systemic administration and to antigen-presenting cells following intramuscular injection. However, achieving systemic mRNA delivery to non-hepatocytes remains challenging without the incorporation of targeting ligands such as antibodies, peptides, or small molecules. Inspired by comb-like polymeric architecture, here we utilized a multiarm-assisted design to construct a library of 270 dendron-like degradable ionizable lipids by altering the structures of amine heads and multiarmed tails for optimal mRNA delivery.

The goat as a model for temporomandibular joint disc replacement: Techniques for scaffold fixation.

A state-of-the-art scaffold capable of efficiently reconstructing the temporomandibular joint (TMJ) disc after discectomy remains elusive. The major challenge has been to identify a degradable scaffold that remodels into TMJ disc-like tissue, and prevents increased joint pathology, among other significant complications. Tissue engineering research provides a foundation for promising approaches towards the creation of successful implants/scaffolds that aim to restore the disc.
