Cone beam computed tomography - extending its arm to explore new possibilities.

Purpose: To determine whether the greyscale value depicted in cone beam computed tomography (CBCT) differentiates different benign osseous lesions of jaws and to measure the greyscale value of various osseous lesions of jaws and to find the correlation (if any) of these greyscale values to that of histopathological diagnosis.

Material And Methods: This study was conducted in the Department of Oral Medicine and Radiology of the Dental Institute after obtaining approval from the Ethical Committee. CBCT scans of osseous lesions of jaws confirmed with histopathological reports depicting cystic or tumour-like lesions were included in the study.

Effect of Fluoride Concentration in Drinking Water on Intelligence Quotient of 12-14-Year-Old Children in Mathura District: A Cross-Sectional Study.

Aims: The aim was to assess and correlate the influence of the concentration of fluoride in ingested water on the intelligence quotient (IQ) of 12-14-year-old youngsters in Mathura district.

Materials And Methods: A total of 219 children were selected, 75 from low F area, 75 medium F area, and 69 from high F area. The concentration of fluoride in the routinely ingested water was estimated using "Ion Selective Electrode method"; then, Raven's Test was utilized to estimate the IQ of the study participants.

Functional investigations of retroviral proteinribonucleic acid complexes by nanospray Fourier transform ion cyclotron resonance mass spectrometry.

Nanospray-FT-ICR has been employed to investigate the processes of genome dimerization, selection, and packaging in human immunodifficiency virus type 1, which are mediated by specific interactions between the nucleocapsid protein (NC) and the structural elements formed by the genome's packaging signal [Psi- ribonucleic acid (RNA)]. This analytical platform allowed for the unambiguous characterization of all the non-covalent complexes formed in vitro by simultaneous RNARNA and proteinRNA binding equilibria. Competitive binding experiments involving the isolated RNA elements were completed to evaluate their ability to sustain specific protein interactions.
