Regionally distinct GFAP promoter expression plays a role in off-target neuron expression following AAV5 transduction.

Astrocyte to neuron reprogramming has been performed using viral delivery of neurogenic transcription factors in GFAP expressing cells. Recent reports of off-target expression in cortical neurons following adeno-associated virus (AAV) transduction to deliver the neurogenic factors have confounded our understanding of the efficacy of direct cellular reprogramming. To shed light on potential mechanisms that may underlie the neuronal off-target expression of GFAP promoter driven expression of neurogenic factors in neurons, two regionally distinct cortices were compared-the motor cortex (MC) and medial prefrontal cortex (mPFC)-and investigated: (1) the regional tropism and astrocyte transduction with an AAV5-GFAP vector, (2) the expression of Gfap in MC and mPFC neurons; and (3) material transfer between astrocytes and neurons.

Executive Summary: Topical Management of Malignant Cutaneous Wounds: Canadian Best Practice Recommendations for Health Care Professionals Developed by Nurses Specialized in Wound, Ostomy and Continence Canada (in collaboration with the Canadian Palliative Care Nursing Association).

Malignant cutaneous wounds pose unique challenges in patient care, requiring specialized attention to alleviate local symptoms and enhance health-related quality of life. As the prevalence of these wounds continues to rise with improving cancer survival rates, it is essential to establish comprehensive best practice recommendations for their topical management. To address this need, a task force was assembled from across Canada, consisting of members from Nurses Specialized in Wound, Ostomy, and Continence Canada and the Canadian Palliative Care Nursing Association.

Structural brain preservation: a potential bridge to future medical technologies.

When faced with the prospect of death, some people would prefer a form of long-term preservation that may allow them to be restored to healthy life in the future, if technology ever develops to the point that this is feasible and humane. Some believe that we may have the capacity to perform this type of experimental preservation today-although it has never been proven-using contemporary methods to preserve the structure of the brain. The idea is that the morphomolecular organization of the brain encodes the information required for psychological properties such as personality and long-term memories.

Offset integrity reduces environmental risk: Using lessons from biodiversity and carbon offsetting to inform water quality offsetting in the catchments of the Great Barrier Reef.

Environmental offsetting has been developed as a mechanism to facilitate the benefits from economic development while avoiding or minimizing environmental harm. This is achieved by compensating for environmental impacts at one location by generating equivalent environmental improvements elsewhere. However, experience with biodiversity and carbon offsetting indicates it can be difficult to ensure the integrity of offsets.
