Wear Resistance of Light-Cure Resin Luting Cements for Ceramic Veneers.

The purpose of this study was to compare the wear resistance of light-cure resin luting cements for veneers with that of other luting materials investigated in earlier studies. An Alabama wear-testing machine was used to measure the wear resistance of four recent light-cure resin luting cements for veneers (G-Cem Veneer; Panavia V5 LC; RelyX Veneer Cement; and Vario-link Esthetic LC). The volume loss ranged from 0.

Development of the membrane ceiling method for in vitro spermatogenesis.

Spermatogenesis is one of the most complex processes of cell differentiation and its failure is a major cause of male infertility. Therefore, a proper model that recapitulates spermatogenesis in vitro has been long sought out for basic and clinical research. Testis organ culture using the gas-liquid interphase method has been shown to support spermatogenesis in mice and rats.

Increase in the number of female doctors and the challenges that Japan's medical system must face.

Japan has seen an increase in female physicians recently, yet it still lags behind other Organization for Economic Cooperation and Development (OECD) countries. A major barrier has been the historical discrimination against women in medical school admissions. In recent years, female enrolment in medical schools has risen, surpassing 40% in 2024, reflecting a broader societal shift.

Disruption of the Enterococcus faecalis-Induced Biofilm on the Intraocular Lens Using Bacteriophages.

Purpose: To compare the effects of bacteriophages (phages) and vancomycin on Enterococcus faecalis-induced biofilms on the intraocular lens.

Methods: E. faecalis strains EF24, GU02, GU03, and phiEF14H1 were used.
