Photo-induced Valence Changes Observed by Photoelectron Spectroscopy of Thin Films of l -Cysteine on Ag(100), (110), and (111) Surfaces Grown in Saliva-emulated Aqueous Solution

Infrared laser-induced valence changes of sulfur, oxygen, and nitrogen atoms of l-cysteine molecules attached to the surfaces of crystalline silver are investigated through photo-electron spectroscopy. The obtained spectra depend on the Miller index of the surface of the silver s...

Descriptive Histological and Histomorphometrical Comparison of Four Xenogeneic and Synthetic Bone Blocks for Mandibular Onlay Augmentation in Rabbits

Background: This exploratory study provided a primarily descriptive comparison of two xenogeneic and two synthetic blocks for mandibular onlay augmentation in rabbits. Methods: Twelve rabbits received bilateral block grafts, providing 24 sites allocated to Bio-Oss® Block, SP-Bloc...

Effect of Silica-Based Abrasive Ingredients on Fluoride Concentration in Toothpaste: An In Vitro and In Vivo Study

Background/Objectives: Toothpastes have recently been developed with purposes ranging from strengthening teeth and restoring periodontal tissue to removing stains and alleviating tooth sensitivity. Although the individual effects of each component are well understood, their inter...

Positive selection of IgG over IgM plasma cells through BCR isotype–specific antigen presentation and signaling

During a primary immune response, B cells can undergo isotype switching from an immunoglobulin M (IgM) B cell receptor (BCR) to an IgG BCR. B cells that have switched to IgG give rise to more bone marrow long-lived plasma cells (PCs) compared with those expressing IgM, but how BC...

Association Between Oral Frailty and Body Mass Index in Late-Stage Older Adults Stratified by Sarcopenia Status

Objectives: Oral frailty is associated with sarcopenia and underweight; however, its relationship with sarcopenic obesity remains unclear. This cross-sectional study investigated the associations between oral frailty and body mass index (BMI) categories (underweight/obesity), str...

Adipose Stem Cell Mitochondrial Transplantation in ART: From Biological Rationale to Clinical Milestone

Oocyte quality is the primary determinant of success in assisted reproductive technologies (ART), and mitochondrial dysfunction is increasingly recognized as a central mediator of poor oocyte competence across advanced maternal age, recurrent implantation failure, polycystic ovar...
