Aim: Calcium silicate-based cements have been widely used in dentistry mainly due to their physicochemical and biological properties. Commercially available materials use radiopacifiers containing metals (bismuth, tantalum, tungsten and/or zirconium). To investigate volumetric changes, in vivo biocompatibility and systemic migration from eight commercially available materials, including powder/liquid and 'ready-to-use' presentations.

Background: Acute neuroinflammatory and oxidative-stress (OS)-inducing stressors, such as high energy and charge (HZE) particle irradiation, produce accelerated aging in the brain. Anti-inflammatory and antioxidant foods, such as blueberries (BB), attenuate neuronal and cognitive deficits when administered to rodents before or both before and after HZE particle exposure. However, the effects of post-stressor treatments are unknown and may be important to repair initial damage and prevent progressive neurodegeneration.

Major depressive disorder (MDD) is a complex neuropsychiatric disorder potentially influenced by factors such as stress and inflammation. Chronic stress can lead to maladaptive brain changes that may trigger immune hyperactivation, contributing to MDD's pathogenesis. While the involvement of inflammation in MDD is well established, the effects of inflammatory preconditioning in animals subsequently exposed to chronic stress remain unclear.

Purpose: To evaluate the peritoneal histopathological changes and culture after the use of intravenous meropenem and intra-abdominal inoculation of 10% aqueous extract of anacardiaceae, in elderly rat model after autogenous fecal peritonitis induced.
Methods: Thirty 18-month-old Wistar rats received induction of autogenous fecal peritonitis and then were stratified into two groups: study I, treated with meropenem (40 mg/kg); and study II, treated with meropenem (40 mg/kg) and intraperitoneal 10% aqueous extract of anacardiaceae. Animals were monitored for 15 days until euthanasia.

cuniculi infection in rabbits represents a true challenge in both diagnosis and treatment of the disease. This study aims to describe and analyze all methods of identifying the presence of the microsporidian in a rabbit through antemortem and postmortem methods. The patient manifested clinical signs of vestibular disease and mild renal symptoms with no significant improvement under treatment, which finally led to euthanasia.
