The management of oral carcinoma leads to both cosmetic and functional deficit to the patient and the confirmatory histopathology is a time consuming process which may be a reason for a reduced follow up and compliance of the patient. We hereby use this study as an opportunity to tell that narrow band imaging (NBI) serves both the above purposes in an earlier period and in a non-invasive manner and thereby improving the lifestyle of the patients. To find out a better non-invasive and time saving diagnostic tool in the management of premalignant and malignant oral lesions in its earlier period. A prospective cross sectional study of 38 patients presenting to the department of ENT, MGMMC, MYH, Indore was taken with suspicious lesions and subjected to endoscopic examination by both white light and NBI and samples were sent to histopathological examination for confirmation. The Intrapapillary Capillary Loop were identified through NBI with Type I (50%) and Type II (31%) to be the most common pattern both correlating with the histopathological squamous cell carcinoma. The sensitivity and specificity of White Light Endoscopy is to be 75.75% and 76.43% respectively and of NBI to be 93.93% and 80% respectively. Narrow band imaging is found to be an optical diagnostic tool in the diagnosis of the lesions at an earlier stage and preventing from further functional and structural deterioration by the disease progression.

Background: 22q11 deletion syndrome consists of a variable grouping of phenotypic features and immunological defects secondary to the loss of genetic material located in the 22q11.2 band. The 22q11 deletion spectrum encompasses different syndromes related to the same etiology and with overlapping anomalies, including DiGeorge syndrome, velocardiofacial syndrome, among others.

Germanium (Ge) colloidal quantum dots (CQDs) were synthesized by thermal decomposition of GeI using capping ligand mixtures of oleylamine (OAm), octadecene (ODE), and trioctylphosphine (TOP). Average diameters could be tuned across a wide range, from 3 to 18 nm, by adjusting reactant concentrations, heating rates, and reaction temperatures. OAm promotes decomposition of GeI to Ge and serves as a weakly bound capping ligand.

The proton bond is a pivotal chemical motif in many areas of science and technology. Its quantum chemical description is remarkably challenged by nuclear and charge delocalization effects and the fluxional perturbation that it induces on molecular substrates. This work seeks insights into proton bonding at sub-kelvin temperatures.

In recent years, research on chiral bound states in the continuum (BIC) has surged, leading to the development of various chiral metasurfaces with narrow bandwidths by breaking of in-plane and out-of-plane symmetries. However, the ability to dynamically tune the working band remains relatively unexplored, which is valuable for chiral sensing applications. Optical phase-change materials, with tunable dielectric constants and switchable properties during phase transition, offer the potential for dynamic control of optical metasurfaces.

Band selection is a common approach to reduce the data dimensionality of hyperspectral imagery. It extracts several bands of importance in some sense by taking advantage of high spectral correlation. In medical imaging, narrow-band imaging (NBI) is an imaging technique for endoscopic diagnostic medical tests, where light of specific blue and green wavelengths is used to enhance the detail of certain aspects of the surface of the mucosa.
