A computational study on dynamic behavior of articular cartilage under cyclic compressive loading and magnetic field.

The dynamic behavior of articular cartilage (a soft porous biological tissue) with strain-dependent nonlinear permeability under cyclic compressive loading and magnetic field is investigated computationally. The compressive force is applied on top surface of the cylindrical plug of the tissue by means of a porous filter. The study of mechanical and deformational behavior of soft porous tissues such as articular cartilage under dynamic compressive loading and magnetic field is useful in understanding the underlying mechano-biological process that may lead to the development of a treatment and recovery protocol in a diseased state.

Comparative bond failure rate of orthodontic brackets when bracket base is treated with micro-abrasive blasting . acid etching: eighteen month randomized control trial and scanning electron microscope study.

Background: The aim of this study was threefold. Firstly, it aimed to introduce and detail a novel method for chemically etching the bases of stainless-steel orthodontic brackets. Secondly, the study sought to investigate the structural alterations within the brackets' microstructure following chemical etching compared to those with sandblasted bases, using electron microscopy analysis.

Cannabis use by individuals with spinal cord injury in the UK: a call for improved patient education and physician awareness for pain and spasticity management.

Study Design: Prospective observational qualitative study.

Objective: Cannabis is used by patients for the treatment of chronic pain, spasticity, sleep issues or mood disorders such as anxiety and depression. Since 2018, it has been authorised in the United Kingdom for medical use as an unlicensed medicine.

Interplay between leadership and patient safety in dentistry: a dental hospital-based cross-sectional study.

Objectives: The study aimed to study the association of leadership practices and patient safety culture in a dental hospital.

Design: Hospital-based, cross-sectional study SETTING: Riphah Dental Hospital (RDH), Islamabad, Pakistan.

Participants: All dentists working at RDH were invited to participate.

Formative experiences and psychological distance in the lives of contemporary environmentalists.

Introduction: We use the term "environmentalists" to describe the people who are highly and actively engaged and involved in environmental issues like climate change. Environmentalists consistently advocate, research, or volunteer to do the work needed to address environmental challenges. Factors that drive contemporary environmentalists remain understudied.
