Self‐oscillating isolated‐buck (fly‐buck) converter [PDF]

open access: yesThe Journal of Engineering, 2021
Abstract This study presents a self‐oscillating fly‐buck converter. The primary objective of this research is to lower the final bill of materials cost of a fly‐buck converter. The fly‐buck converter is based on a relaxation self‐oscillation circuit.

PGAM5 promotes lasting FoxO activation after developmental mitochondrial stress and extends lifespan in Drosophila

open access: yeseLife, 2017
The mitochondrial unfolded protein response (UPRmt) has been associated with long lifespan across metazoans. In Caenorhabditis elegans, mild developmental mitochondrial stress activates UPRmt reporters and extends lifespan.

Loss of a proteostatic checkpoint in intestinal stem cells contributes to age-related epithelial dysfunction

open access: yesNature Communications, 2019
Protein homeostasis maintenance (proteostasis) is critical for cell function, but declines during aging. Here the authors detail a proteostatic checkpoint in Drosophila intestinal stem cells coordinating cell cycle arrest with protein aggregate clearance,

Cellular Senescence Is Induced by the Environmental Neurotoxin Paraquat and Contributes to Neuropathology Linked to Parkinson’s Disease

open access: yesCell Reports, 2018
Exposure to the herbicide paraquat (PQ) is associated with an increased risk of idiopathic Parkinson’s disease (PD). Therapies based on PQ’s presumed mechanisms of action have not, however, yielded effective disease therapies.

Viral gene drive in herpesviruses

open access: yesNature Communications, 2020
Current gene drive strategies are restricted to sexually reproducing species. Here the authors develop a gene drive in herpesviruses that allows the spread of an engineered trait through a viral population.
