'We are largely left out': workplace and psychosocial experiences of Australian general practitioners during the initial months of the COVID-19 pandemic.

Background: The COVID-19 pandemic continues to exert a significant toll on the Australian primary healthcare system. Although wellbeing challenges faced by hospital-based healthcare workers are widely discussed, less is known about the experiences of general practitioners (GPs) during the initial phases of the pandemic. This paper reports qualitative survey data from Australian GPs, examining their workplace and psychosocial experiences during the initial months of the pandemic.

Biomechanics and strain mapping in bone as related to immediately-loaded dental implants.

The effects of alveolar bone socket geometry and bone-implant contact on implant biomechanics, and resulting strain distributions in bone were investigated. Following extraction of lateral incisors on a cadaver mandible, implants were placed immediately and bone-implant contact area, stability implant biomechanics and bone strain were measured. In situ biomechanical testing coupled with micro X-ray microscopy (µ-XRM) illustrated less stiff bone-implant complexes (701-822 N/mm) compared with bone-periodontal ligament (PDL)-tooth complexes (791-913 N/mm).

Stem cell factor and granulocyte colony-stimulating factor reduce β-amyloid deposits in the brains of APP/PS1 transgenic mice.

Introduction: Alzheimer's disease (AD) is widely recognized as a serious public health problem and heavy financial burden. Currently, there is no treatment that can delay or stop the progressive brain damage in AD. Recently, we demonstrated that stem cell factor (SCF) in combination with granulocyte colony-stimulating factor (G-CSF) (SCF+G-CSF) has therapeutic effects on chronic stroke.
