In the title compound, C21H24N2O2Si, a new pyridazin-3(2H)-one derivative, the carbonyl group of the heterocyclic ring and the O atom of the silyl ether are located on the same side of the pyridazinone ring and the C-C-O-Si torsion angle is -140.69 (17)°. In the crystal, mol-ecules are linked by pairs of strong N-H⋯O hydrogen bonds into centrosymmetric dimers with graph-set notation R 2 (2)(8). Weak C-H⋯π inter-actions are also observed.

Background The accurate diagnosis of intraductal carcinoma of the prostate (IDC-P) is occasionally challenging due to the similarity in pathological morphology between IDC-P and high-grade prostatic intraepithelial neoplasia (HGPIN). In this report, we reviewed the pathology of cases previously diagnosed as HGPIN to search for IDC-P cases effectively. In addition, we examined whether those cases had genetic abnormalities.

Department of Prosthodontics/Dental Material, Dr. Ziauddin Ahmad Dental College, Aligarh Muslim University, India.
Objectives: Calcium ions (Ca) play crucial role in tooth development, particularly in maintaining enamel density during amelogenesis. Ameloblasts require specific proteins such as amelogenin, ameloblastin, enamelin, kallikrein, and collagen for enamel growth. Recent research has highlighted the importance of calcium and fluoride ions, as well as the TRPM7, STIM, and SOCE pathways, in regulating various stages of enamel formation.

Objectives: To gain insight into the integrity of research in Otolaryngology-Head & Neck Surgery (OHNS) literature through characterising retracted articles, analysing the reason for their retraction, and the trends in the collected data.
Methods: Pubmed, Embase, and Retraction Watch Database were queried for retracted articles published between the dates of 1/31/92 and 9/30/22. Articles with titles relating to OHNS subjects and published in OHNS journals, as determined by Scimago Journal and Country Ranking, were selected for further analysis.
