Erythropoietin-producing hepatocellular (Eph) receptors comprise the largest group of surface receptors and are responsible for cellular signals. Eph/ephrin signaling has been identified to play a role in key cancer development and progression processes, especially in the upper gastrointestinal tract. The Eph/ephrin system has been described as a tumor suppressor in duodenal cancer, while in esophageal, gastric, hepatic, and pancreatic cancer, the system has been related to tumor progression.

Titanium dioxide nanotubes incorporated into conventional glass ionomer cement alter the biological behavior of pre-odontoblastic cells.

Colloids Surf B Biointerfaces

February 2025

Faculdade São Leopoldo Mandic (SLMANDIC), Rua José Rocha Junqueira 13, Swift, Campinas, SP 13045-755, Brazil; Department of Comprehensive Dentistry, University of Maryland, School of Dentistry, 650 W Baltimore St., Baltimore, MD 21201, USA. Electronic address:

The objective was to address the repercussion of adding titanium dioxide nanotubes (TiO-nt) into high-viscosity conventional glass ionomer cement (GIC) on the biological properties of pre-odontoblastic cells (MDPC-23) challenged by lipopolysaccharides (LPS - 2 μg/mL). TiO-nt was added to Ketac Molar EasyMix at 3, 5, 7 %, whereas unblended GIC served as control. Analyses included proliferation (n=6; 24, 48, 72 h), metabolism (MTT; n=6; 24, 48, 72 h); morphology laser microscopy (n=3; 24, 48, 72 h); proteome assessments IL-1β, IL-6, IL-10, VEGF, TNF-α (n=3; 12, 18 h); mRNA levels (RT-PCR) of Il-1β, Il-6, Il-10, VEGF, TNF-α (n=3; 12, 18 h) and DSPP (n=3; 24, 72, 120 h).

Article Synopsis
  • * This review examines existing research on the prognostic implications of HNSCC’s histopathologic subtypes, noting a lack of studies focusing specifically on treatment outcomes for each subtype.
  • * The review highlights that some subtypes, like verrucous and cuniculatum, have better prognoses compared to others like basaloid and spindle cell, and it emphasizes the need for more molecular research to develop targeted therapies and improve prognostic assessments.

Pathogens

September 2024

Department of Morphology and Pathology & Biotechnology Graduate Program (PPGBiotec), Center for Biological and Health Sciences (CCBS), Federal University of São Carlos (UFSCar), Km 235 Washington Luís Road, São Carlos 13565-905, SP, Brazil.

Article Synopsis
  • - The study analyzed the presence and behavior of oral bacteria in 59 patients with orofacial clefts receiving surgical rehabilitation, focusing on factors like age, gender, and surgical history.
  • - Salivary samples were collected and tested using traditional microbiological methods and advanced techniques to identify MRSA strains and overall staphylococcal colonization, with 55.9% of patients showing signs of colonization at different points.
  • - Factors influencing oral bacterial colonization during treatment included surgical asepsis practices, the potential for new bacterial colonization in treated areas, and the patients' repeat visits to medical facilities, which might elevate MRSA acquisition risk.

Improving Self-Healing Dental-Restorative Materials with Functionalized and Reinforced Microcapsules.

Polymers (Basel)

August 2024

Division of Biomaterial and Biomedical Sciences, Department of Oral Rehabilitation and Biosciences, Oregon Health & Science University, Portland, OR 97201, USA.

Article Synopsis
  • Dental resin composites often fail due to microcracks that can lead to larger cracks and restoration issues.
  • The study focuses on enhancing self-healing dental resins through the optimization of microcapsules that release healing agents when damaged.
  • Functionalized microcapsules with silanizing agents showed better healing efficiency, particularly the bilayer approach using TEOS and MPTMS, achieving up to 35% toughness recovery compared to standard microcapsules.

Objectives: To assess the impact of different concentrations TiO-nt incorporated into a glass ionomer cement on the proliferation, mitochondrial metabolism, morphology, and pro- and anti-inflammatory cytokine production of cultured fibroblasts (NIH/3T3), whether or not stimulated by lipopolysaccharides (LPS-2 μg/mL, 24 h).

Methods: TiO-nt was added to KM (Ketac Molar EasyMix™, 3 %, 5 %, 7 % in weight); unblended KM was used as the control. The analyses included: Cell proliferation assay (n = 6; 24/48/72h); Mitochondrial metabolism assay (n = 6; 24/48/72h); Confocal laser microscopy (n = 3; 24/48/72h); Determination of biomarkers (IL-1β/IL-6/IL-10/VEGF/TNF) by using both multiplex technology (n = 6; 12/18 h) and the quantitative real-time PCR assay (q-PCR) (n = 3, 24/72/120 h).

Objectives: This prospective randomized multicenter clinical trial (PRMCT) investigated postoperative pain after single-visit root canal treatments in teeth affected by pulp necrosis (PN), and asymptomatic apical periodontitis (AAP) (with apical radiolucent areas) or normal periradicular tissues (without apical radiolucent areas) comparing different instruments' kinematics and apical instrumentation limits.

Methods: Before chemomechanical preparation, 240 patients/teeth were randomly distributed into four groups (n = 60) according to the instruments' kinematics (rotary or reciprocating) and apical instrumentation limits (with or without intentional foraminal enlargement [IFE]). After that, specimens were submitted to the same irrigation and obturation techniques, and the patients were referred to undergo the definitive restorations.

Article Synopsis
  • The study examined the occurrence of luxation injuries and related dental fractures in patients treated at a Brazilian dental school clinic from 2012 to 2022.
  • Data were collected from 366 clinical records, highlighting that men were more likely to experience luxation injuries than women, with extrusive luxation being the most common type.
  • Results indicated that patients with luxation injuries sought care more quickly and had a higher likelihood of needing endodontic treatment, particularly for injuries resulting from traffic accidents, though luxation combined with fractures did not increase treatment needs.

Placenta

January 2023

Department of Pathology, School of Medical Sciences, University of Campinas (UNICAMP), Campinas, São Paulo, Brazil; Department of Pathology, School of Medicine, University of Utah (UU), Salt Lake City, UT, United States. Electronic address:

Article Synopsis
  • - Villitis of unknown etiology (VUE) is an inflammatory condition marked by the presence of maternal CD8 +T cells in the placenta, with its causes still under discussion.
  • - The disease likely stems from immune system dysregulation, where maternal T cells react to fetal antigens, prompting the onset of VUE.
  • - This review draws parallels between VUE, graft vs host disease (GVHD), and allograft rejection to deepen understanding of VUE's mechanisms, potentially informing future treatment approaches.
