Physical, chemical and biological properties of MTA Angelus and novel AGM MTA: an in vitro analysis.

Introduction: Mineral trioxide aggregate (MTA) is a calcium silicate-based cement that has changed conventional dental therapeutic approaches. This study aimed to evaluate physical, chemical and biological properties of novel AGM MTA, in comparison with MTA Angelus.

Methods: The samples were prepared according to the manufacturer's instructions.

The relationship between intrinsic capacity and functional ability in older adults.

Introduction: Intrinsic Capacity in integrated geriatric care emphasizes the importance of a thorough functional assessment. Monitoring the intrinsic capacity of older individuals provides standardized and reliable information to prevent early disability. This study assessed the relationship between intrinsic capacity and functional ability in older adults.

Neural reshaping: the plasticity of human brain and artificial intelligence in the learning process.

Unlabelled: This study explores the concept of neural reshaping and the mechanisms through which both human and artificial intelligence adapt and learn.

Objectives: To investigate the parallels and distinctions between human brain plasticity and artificial neural network plasticity, with a focus on their learning processes.

Methods: A comparative analysis was conducted using literature reviews and machine learning experiments, specifically employing a multi-layer perceptron neural network to examine regression and classification problems.

Effects of cypermethrin exposure on learning and memory functions and anxiety-like behavior in rats.

Background: Cypermethrin (CYP), a synthetic pyrethroid widely used to control plant pests, has been associated with various diseases in humans exposed to pesticides, either directly or indirectly. This study aimed to examine the effects of CYP on learning and memory functions, as well as anxiety-like behavior.

Methods: Forty male Wistar rats (8 weeks old) were randomly assigned to 4 groups: The first group served as the control, while the other three groups received different doses of CYP (5, 20, and 80 mg/kg) via gavage once daily for one month.

Delays in chemotherapy and radiotherapy of breast cancer during COVID-19 pandemic.

Background: During the COVID-19 pandemic, hospitals were overwhelmed with infected patients, leading to a disruption in the delivery of services. Patients with cancer, including breast cancer, rely on timely treatment, as delays can reduce survival rates. In this study, we investigated delays in treatment and the factors contributing to delays in chemotherapy and radiotherapy for these patients.
