Influence of a High-fat Diet in the Progression of Apical Periodontitis.

Introduction: This study evaluated the effects of a high-fat diet (HFD) on the progression of apical periodontitis (AP) in rats.

Methods: Eight-week old Wistar rats (N = 24) were included in this study. Half of the animals received an HFD and the other half a control diet (CD).

Cigarette smoke impairs granulosa cell proliferation and oocyte growth after exposure cessation in young Swiss mice: an experimental study.

Background: Cigarette smoke is associated with decreased female fertility, causing damage to ovarian function and disturbing follicle development. However, the effects of cigarette toxicants on ovarian function depend on duration and intensity of exposure. The aim of this study was to assess the effects of brief, intense exposure to tobacco smoke on granulosa cell number, oocyte growth, and follicle size during puberty in female Swiss mice.
