Comparative Evaluation of Penetration of Various Nano-sized Intra-canal Medicaments: An Confocal Laser Scanning Microscopic Study.

Background: To assess and contrast the depth of penetration of conventional calcium hydroxide, nanoparticle calcium hydroxide, silver nanoparticles, and combination of nanoparticle calcium hydroxide and silver nanoparticles into dentinal tubules using confocal laser scanning microscope.

Materials And Methods: Eighty human single-rooted teeth were decoronated and instrumented up to Protaper Universal F3. Teeth were separated into four groups at random ( = 20) following chemomechanical preparation.

A comparative study on surgical outcomes of trabeculectomy with and without anti-metabolites in juvenile open-angle glaucoma.

Purpose: To compare the surgical outcomes of trabeculectomy with and without anti-metabolites in patients with juvenile open-angle glaucoma (JOAG).

Methods: This retrospective comparative case series included 98 eyes of 66 patients with JOAG who underwent either trabeculectomy without anti-metabolites (group A, n = 53 eyes) or with anti-metabolites (group B, n = 45 eyes) with a minimum of 2 years follow-up. The main outcome measures were intra-ocular pressure (IOP), number of glaucoma medications, visual acuity, additional surgical interventions, surgical complications, and risk factors for failure.

Molecular dynamics simulation study on EngA: the presence of Mg at the active-sites promotes the functionally important conformation.

EngA, a GTPase contains two GTP binding domains [GD1, GD2], and the C-terminal KH domain shown to be involved in the later stages of ribosome maturation. Association of EngA to the ribosomal subunit in the intermediate stage of maturation is essential for complete ribosome maturation. However, this association was shown to be dependent on the nucleotide bound combinations.

A cationic amino acid polymer nanocarrier synthesized in supercritical CO for co-delivery of drug and gene to cervical cancer cells.

The present study was undertaken to investigate the ability of a drug curcumin-loaded polymer to inhibit the growth of cervical cancer cells by enhancing the anti-cancer efficiency of curcumin. We synthesized poly(methacryloyl beta-alanine) (PMBA) as a nanocarrier by radical polymerization in supercritical CO. The results showed that the curcumin encapsulated and folic acid (FA)-treated PMBA (Poly@Cur-FA) for 24 h activated the reactive oxygen species-mediated programmed cell death machinery in HeLa cells.
