Incidental findings on cone beam computed tomography and reasons for referral by dental practitioners in indore city (m.p).

Abstract: Materials and Methods: A retrospective analysis of 795 records that were referred for CBCT imaging at Institutional and Oracal CBCT Centre, Indore was undertaken. Referrals from both within and outside institution, as well as from private practitioners were considered. The reason for CBCT referral, provision diagnosis, final diagnosis and any incidental diagnosis were recorded. results: This retrospective chart audit revealed that 56.7 % were male and 43.3% were females. Greatest source of patients was referred by oral surgeons (21.9%) followed by oral and maxillofacial radiologist (14.2%) and prosthodontist (9.3%). The most common reason for referral was for implant analysis (24.2%) and the most common incidental finding diagnosed by CBCT was oral malignancies. conclusion: In Institutional set­up, CBCT referrals were mostly for the reason of planning implant placement followed by trauma whereas private practitioners used CBCT mostly for implant placement followed by impaction. CBCT was being utilized more by Oral surgeons in private sector whereas it in an Institutional setup majority of referrals from Department of Oral Diagnosis and Radiology. Findings that were most commonly diagnosed incidentally on CBCT were Orofacial malignancies followed maxillary sinus pathologies.

QSAR studies on imidazopyridazine derivatives as PfPK7 inhibitors

Abstract: Quantitative structure–activity relationship (QSAR) studies were carried out on a series of 35 recently synthesised imidazopyridazine derivatives to investigate the structural requirements of their inhibitory activity against malarial kinase, Plasmodium falciparum protein kinase 7 (PfPK7). Partial least square (PLS) methodology coupled with various feature selection methods, viz. stepwise (SW), genetic algorithm (GA) and simulated annealing, was applied to derive QSAR models which were further validated for statistical significance and predictive ability by internal and external validation. The statistically significant best 2D-QSAR model having correlation coefficient r 2 = 0.9190 and cross-validated squared correlation coefficient q 2 = 0.8575 with external predictive ability of pred_r 2 = 0.7212 was developed by SW-PLS with the descriptors like StNE-index, T_N_O_2, T_N_O_7, YcompDipole and SaasCE-index. Molecular field analysis was used to construct the best 3D-QSAR model using GA-PLS method, showing g...

Soft X-Ray Emission in the (1.0-1.5 keV) Window with Nitrogen Filling in a Low Energy Plasma Focus

Abstract: A study of soft X-ray emission in the 1.0–1.5 keV energy range from a low energy (1.15 kJ) plasma focus has been conducted. X-rays are detected with the combination of Quantrad Si PIN-diodes masked with Al (50 μm), Mg (100 μm) and Ni (17.5 μm) filters and with a pinhole camera. The X-ray flux is found to be measurable within the pressure range of 0.1–1.0 mbar nitrogen. In the 1.0–1.3 keV and 1.0–1.5 keV windows, the X-ray yield in 4π-geometry is 1.03 J and 14.0-J, respectively, at a filling pressure of 0.25 mbar and the corresponding efficiencies are 0.04% and 1.22%. The total X-ray emission in 4π-geometry is 21.8 J, which corresponds to the system efficiency of about 1.9%. The X-ray emission is found dominantly as a result of the interaction of energetic electrons in the current sheath with the anode tip. Images recorded by the pinhole camera confirm the emission of X-rays from the tip of the anode.

Nano-micronutrients [γ-Fe2O3 (iron) and ZnO (zinc)]: green preparation, characterization, agro-morphological characteristics and crop productivity studies in two crops (rice and maize)

Abstract: Nanotechnology based fertilizer production possessing the desired chemical composition, can improve plant nutrition and may reduce the environmental impact and enhance the plant productivity. In this work, we have demonstrated the green preparation and characterization of nano iron (γ-Fe2O3) and zinc (ZnO), and the subsequent agro-morphological modification (germination, shoot length, root length, seedling length, vigor index and dry matter production (DMP) (fresh and dry weight), the effect on the crop productivity (1000 grain weight, seed length, seed thickness, seed width) and the mechanism of uptake in rice (Oryza sativa) and maize (Zea mays L.). The highest seed germination percentage (100%) and seedling vigor index values (27 500 and 36 500) were observed after using 500 ppm of nanoscale γ-Fe2O3 treatment in rice and maize, respectively. In the case of nanoscale ZnO, the highest seed germination percentages (100% and 99%) and seedling vigor index values (32 400 and 33 660) were observed at 1000 and 2000 ppm in rice and maize seeds, respectively. The results of the micro plot field studies revealed that yield attributes such as the total grain weight (g m−2), 1000 grain weight, seed length, seed thickness, seed width and yield (kg ha−1) were also highly influenced by the foliar application of nanoscale γ-Fe2O3 (500 ppm) and ZnO (750 ppm) in rice and maize, respectively.
