Preoperative Assessment of Medication-Related Osteonecrosis of the Jaw Using [18F]fluoride Positron Emission Tomography (PET)/CT and [18F]fluorodeoxyglucose PET/MRI in Correlation with Histomorphometry and Micro-CT—A Prospective Comparative Study

open access: yesDiagnostics
Objectives: The purpose of this study was to investigate the imaging characteristics of medication-related osteonecrosis of the jaw (MRONJ) using [18F]fluoride positron emission tomography/computed tomography (PET/CT) and [18F]fluorodeoxyglucose (FDG ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, Volume 600, Issue 11, Page 1621-1637, June 2026.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

pH-Sensitive mesoporous zirconium diphosphonates for controllable colon-targeted delivery

open access: yes, 2010
pH-Sensitive mesoporous zirconium diphosphonates have been successfully synthesized through the surfactant-assisted procedure using the organophosphonate derivative of piperazine, 1,4-bis(phosphomethyl)piperazine (BPMP), and ZrCl4 as the metal precursor.

Interactions at the Organic/Inorganic Interface:  Molecular Modeling of the Interaction between Diphosphonates and the Surfaces of Barite Crystals

open access: yes, 2016
Molecular modeling techniques are used to investigate the interaction of alkyldiphosphonate molecular anions with the surfaces of barium sulfate. We show that the most stable sites are on the (100) and (011) surfaces with the [PO3]2- groups of the ...

Systemic amyloid light‐chain amyloidosis beyond ANDROMEDA: Diagnostic challenges and therapeutic updates

open access: yesCA: A Cancer Journal for Clinicians, Volume 76, Issue 3, May/June 2026.
Abstract Systemic immunoglobulin light‐chain amyloidosis is a rare but life‐threatening plasma cell disorder characterized by the production of misfolded monoclonal light chains that deposit as amyloid fibrils, leading to pathologic tissue remodeling and progressive multiorgan dysfunction.

Nitroxide‐Mediated Polymerization Synthesis of Geminal Bisphosphonate‐Functionalized (Co)polymers and Their Affinity to Hydroxyapatite Surface

open access: yesJournal of Polymer Science, Volume 64, Issue 8, Page 1692-1703, 15 April 2026.
A novel styrenic monomer bearing gem‐bisphosphonate groups is synthesized in a single step. The nitroxide‐mediated (co)polymerization of this monomer proceeds in a well‐controlled manner, yielding bisphosphonate‐functionalized (co)polymers with low dispersity.

Bipyridine-triggered modulation of structure and properties of zinc-diphosphonates: coordination role vs. template rule

open access: yes, 2018
Two layered zinc-diphosphonates driven by 4,4′-bipy are prepared and their structural diversities are caused by the distinct roles of 4,4′-bipy in the process of assembly. The luminescence and proton conduction are studied.

Influence of bisphosphonates on alveolar bone density: a histomorphometric analysis

open access: yesBrazilian Oral Research, 2010
This study is a histomorphometrical analysis of the influence of the bisphosphonate alendronate on alveolar bone density. Eighteen male Wistar rats were randomly assigned to a control group (n = 9) that received no medication and an experimental group (n
