Comparative analysis of remineralizing efficacy of strontium-doped bioactive glass, BioMin, and NovaMin containing dentifrice on artificial white spot lesions after chlorhexidine pretreatment - An study.

Aim: This study aimed to compare the remineralizing efficacy of strontium-doped bioactive glass, BioMin, and NovaMin containing dentifrices on artificial white spot lesions (WSLs) after chlorhexidine (CHX) pretreatment using energy-dispersive X-ray analysis (EDAX).

Materials And Methodology: Twenty-four samples of maxillary first premolars extracted for orthodontic purposes were selected. Artificial WSLs were produced by immersing the samples in a prepared demineralizing solution for 3 days.

Design, fabrication and performance assessment of a solar cooker with optimum composition of heat storage materials.

Solar energy as an inexhaustible source of energy has been the primary interest of many researchers for the last four to five decades due to its wide applications such as domestic cooking systems. The current work aims to determine the optimum cooker surface area with the aid of analytical heat loss and design equations. The top, bottom and side heat loss coefficients are calculated by an iterative procedure solved using MATLAB.

Computational investigations on the hemodynamic performance of a new swirl generator in bifurcated arteries.

Hemodynamic behaviour of blood in the bifurcated arteries are closely related to the development of cardiovascular disease. The secondary flows generated at the bifurcation zone promotes the deposition of atherogenic particles on the outer walls. The present study aims at suppressing the development of atherosclerosis plaque by inducing helical flow structure in the arterial passage.

Metastasis of renal cell carcinoma to urinary bladder: A rare case report with review of literature.

Metachronous metastatic renal cell carcinoma (RCC) to bladder is rare incidence. We report a case of RCC with metachronous metastasis to the urinary bladder occurring 2 years postradical nephrectomy. In a follow-up for the past 1 year, the patient is doing well.
