Impact of bismuth oxide on structural, optical and gamma-ray shielding properties of calcium-sodium-borate glasses.

In the present study, we have prepared six glass samples of bismuth borate using the melt-quenching method with the composition (70-x)B2O3-10CaO-20Na2O-xBi2O3; x = 0, 3, 6, 9, 12 and 15 mol%. The density of the prepared glasses was determined using Archimedes principle. The X-ray diffraction patterns provide confirmation of the amorphous nature of the prepared samples, whereas the Fourier transform infrared measurements pointed to the existence of structural units like BO3, BO4, BiO3 and BiO6 within the glass network.

Assessment of Knowledge and Attitude Regarding Teledentistry Among Dental Professionals: A Cross-Sectional Study.

Background: Modern technologies have led to the development of new tools, practices, and digital techniques. However, their use in public health to provide adequate oral health facilities to the community is limited. One of the facilities that can help provide better oral health with minimal cost is teledentistry.

Assessment of Posterior Pharyngeal Airway Changes After Orthognathic Surgery Using Barium Sulfate.

Introduction:  Obstructive sleep apnea (OSA), caused by airway narrowing, is likely to occur if the mandibular plane to hyoid distance is greater than 15.4 mm and the posterior airway space (PAS) is less than 11 mm. OSA may be caused by mandibular deficit, bimaxillary retrusion, increased lower facial height, extended soft palate, a large tongue base, and a posteroinferiorly positioned hyoid bone.

Comparative Evaluation of Postoperative Pain in Primary Teeth Obturated With Zinc Oxide Eugenol versus Metapex: A Randomized Clinical Trial.

The fundamental objective of pulp treatment is to preserve the integrity and health of oral tissues. Pulp necrosis or irreversible pulpitis is the key indication for performing pulpectomy in primary teeth. It can be performed as a single-visit or multi-visit procedure using suitable obturating material.

Superolateral dislocation of the intact mandibular condyle: report of a rare case with a review.

Dislocation of the temporomandibular joint, which represents 3% of all dislocated joints reported in the body, occurs when the mandibular condyle is displaced anteriorly beyond the articular eminence. Although anterior dislocation of the mandibular condyle is well documented in the literature, superior, lateral, and posterior dislocation of the condyle is rare. Only a few reports documenting superolateral dislocation with anterior mandible fractures have been published in the past.

A facile and green strategy for the synthesis of Au, Ag and Au-Ag alloy nanoparticles using aerial parts of R. hypocrateriformis extract and their biological evaluation.

A facile and green strategy is reported here to synthesize gold (Au), silver (Ag) and gold-silver (Au-Ag) alloy nanoparticles (NPs) through bio-reduction reactions of aqueous corresponding metal precursors mediated by extracts of aerial parts of R. hypocrateriformis, which act as both reducing and stabilizing agents, under microwave irradiation. UV-vis spectrophotometer, XRD, FT-IR, FESEM/TEM, TGA and EDAX analysis were used to characterize the obtained NPs.

Development and Characterization of Genic SSR Markers from Indian Mulberry Transcriptome and Their Transferability to Related Species of Moraceae.

Improving mulberry leaf production with enhanced leaf quality holds the key to sustain the ever increasing demand for silk. Adoption of modern genomic approaches for crop improvement is severely constrained by the lack of sufficient molecular markers in mulberry. Here, we report development and validation of 206 EST derived SSR markers using transcriptome data generated from leaf tissue of a drought tolerant mulberry genotype, Dudia white.

A mini library of novel triazolothiadiazepinylindole analogues: synthesis, antioxidant and antimicrobial evaluations.

A new series of novel triazolothiadiazepinylindole analogues were synthesized with an aim to examine possible antioxidant and antimicrobial activities. The titled compounds (3a-z) were obtained in good yield by reacting 5-(5-substituted-3-phenyl-1H-indol-2-yl)-4-amino-4H-1,2,4-triazole-3-thiols 1a-c with 3-(2,5-disubstituted-1H-indol-3-yl)-1(4-substituted phenyl)prop-2-en-1-ones 2a-i. All the newly synthesized compounds were characterized by IR, (1)H NMR, mass spectroscopic and analytical data.

Development and characterization of microsatellite markers for Morus spp. and assessment of their transferability to other closely related species.

Background: Adoption of genomics based breeding has emerged as a promising approach for achieving comprehensive crop improvement. Such an approach is more relevant in the case of perennial species like mulberry. However, unavailability of genomic resources of co-dominant marker systems has been the major constraint for adopting molecular breeding to achieve genetic enhancement of Mulberry.

Solvent-free, microwave assisted Knoevenagel condensation of novel 2,5-disubstituted indole analogues and their biological evaluation.

A rapid, efficient and environmental benign methodology for the preparation of 2,5-disubstituted indole analogues is developed. 2,5-Disubstituted indole-3-carboxaldehydes (1a-c) undergo Knoevenagel condensation with barbiturates (2 &4), thiazolidine-2,4-dione (6) and 3-methyl-1H-pyrazol-5(4H)-one (8) in solvent-free, NH(4)OAc catalyzed, microwave assisted reaction. Structures of the products thus obtained were confirmed by their m.

Synthesis, antioxidant and DNA cleavage activities of novel indole derivatives.

A new series of novel indole derivatives containing barbitone moiety (5a-i) are synthesized by simple and efficient condensation of chalcones (3a-i) with barbituric acid (4). The synthesized compounds are screened for their antioxidant (free radical scavenging, total antioxidant capacity and ferric reducing antioxidant power) and DNA cleavage activities were evaluated. Among the synthesized compounds (5a), (5d) and (5g) exhibited excellent antioxidant activity and all the tested compounds in the series have exhibited promising DNA cleavage activities.

Potential transition state phosphoramidate inhibitors of beta-tubulin as antifilarial agents.

Transition state phosphoramidate inhibitors of beta-tubulin were designed as potential antifilarial agents. The reaction of 2-aminobenzimidazole with diisopropyl phosphite and carbon tetrachloride at a low temperature gave the unexpected 1-diisopropoxyphosphoryl-2-aminobenzimidazole, which on heating gave the novel benzimidazole derivative, 2-(diisopropoxyphosphoryl)aminobenzimidazole. Both products were fully characterized and the synthetic procedure to both compounds was optimized.
