Objective: This review article discusses investigational subretinal gene therapies for retinal vascular diseases, including AVA-101, an adeno-associated viral (AAV) 2 vector expressing soluble vascular endothelial growth factor (VEGF) receptor 1, ABBV-RGX-314, an AAV8 vector expressing an anti-VEGF-A antibody fragment, and EXG102-031, an AAV8 vector expressing a recombinant protein that blocks VEGF family members and angiopoietin 2.

Design: Review article CONCLUSION: Subretinal injection is a commonly used delivery route for investigational gene therapy agents which is theorized to provide relative immune privilege, thereby reducing the risk of inflammation, while providing high transgene expression in photoreceptors and retinal pigment epithelium. Subretinal injection of AVA-101 demonstrated safety and tolerability in Phase I and IIa trials, but failed to maintain visual acuity and control exudation.

Fire exclusion over the last two centuries has driven a significant fire deficit in the forests of western North America, leading to widespread changes in the composition and structure of these historically fire-adapted ecosystems. Fuel treatments have been increasingly applied over the last few decades to mitigate fire hazard, yet it is unclear whether these fuel-focused treatments restore the fire-adapted conditions and species that will allow forests to persist into the future. A vital prerequisite of restoring fire-adaptedness is ongoing establishment of fire-tolerant tree species, and both the type and reoccurrence of fuel treatments are likely to strongly influence stand trajectories.

Assessing the basis for regulatory crediting of virus LRVs for secondary biological wastewater treatment: A systematic review.

Water Res

November 2024

Southern Nevada Water Authority, P.O. Box 99954, Las Vegas, NV 89193, United States. Electronic address:

Regulatory frameworks for potable reuse often include stringent log reduction value (LRV) targets to ensure public health protection against exposure to viruses and protozoa. To achieve overall LRV targets and reduce associated capital and operational costs, it is important to maximize LRV credits awarded to each unit process in a potable reuse treatment train. This may include processes that are historically uncredited or undercredited, such as secondary biological wastewater treatment incorporating activated sludge and secondary clarification.
