Modifying reaction time tasks parameters in the automated IntelliCage identifies heightened impulsivity and impaired attention in the 3xTg-AD model of Alzheimer's disease.

Background: The 3xTg-AD transgenic mouse model of Alzheimer's disease (AD) is an important tool to investigate the relationship between development of pathological amyloid-β (Aβ) and tau, neuroinflammation, and cognitive impairments. Traditional behavioral tasks assessing aspects of learning and memory, such as mazes requiring spatial navigation, unfortunately suffer from several shortcomings, including the stress of human handling and not probing species-typical behavior. The automated IntelliCage system was developed to circumvent such issues by testing mice in a social environment while measuring multiple aspects of cognition.

Postsurgical consequences in lower third molar surgical extraction using micromotor and piezosurgery.

Background: One of the most critical and crucial steps in surgical extraction is cutting the bone or osteotomy, for which many techniques are used, e.g., chisels and mallet, rotary instruments, and ultrasound bone-cutting instruments.

Unicystic ameloblastoma with mural proliferation: conservative or surgical approach?

Ameloblastoma occurs in a wide variety of forms. Various forms of ameloblastomas have various treatment modalities ranging from a conservative approach to surgical resection with reconstruction. We report a case of unicystic ameloblastoma with mural proliferation in a 17-year-old girl, who presented with a swelling in the lower left jaw associated with dull aching pain and was managed initially by a conservative approach followed by surgical enucleation on recurrence.
