A scanning electron microscopic study evaluating the sealing ability of MTA, BiodentineTM, and new light-cure MTA used for furcal perforation repair.

Background: To evaluate and compare the sealing ability of Mineral trioxide aggregate (MTA), BiodentineTM and light cure MTA used for the repair of furcal perforations using scanning electron microscope (SEM).

Material And Methods: The study sample comprised 45 extracted mandibular molars. The teeth were embedded in modeling wax.

Co-infection of malaria and dengue in pregnant women with SARS-CoV-2.

Physicians and obstetricians should be vigilant so that they can swiftly identify co‐infections of malaria and dengue in pregnant women with COVID‐19.

Review of the systems biology of the immune system using agent-based models.

The immune system is an inherent protection system in vertebrate animals including human beings that exhibit properties such as self-organisation, self-adaptation, learning, and recognition. It interacts with the other allied systems such as the gut and lymph nodes. There is a need for immune system modelling to know about its complex internal mechanism, to understand how it maintains the homoeostasis, and how it interacts with the other systems.
