3D printing-based frugal manufacturing of glass pipettes for minimally invasive delivery of therapeutics to the brain.
Article in Neuroprotection (Chichester, England), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: Intracerebral delivery of agents in liquid form is usually achieved through commercially available and durable metal needles. However, their size and texture may contribute to mechanical brain damage. Glass pipettes with a thin tip may significantly reduce injection-associated brain damage but require access to prohibitively expensive programmable pipette pullers. This study is to remove the economic barrier to the application of minimally invasive delivery of therapeutics to the brain, such as chemical compounds, viral vectors, and cells. Methods: We took advantage of the rapid development of free educational online resources and emerging low-cost 3D printers by designing an affordable pipette puller (APP) to remove the cost obstacle. Results: We showed that our APP could produce glass pipettes with a sharp tip opening down to 20 μm or less, which is sufficiently thin for the delivery of therapeutics into the brain. A pipeline from pipette pulling to brain injection using low-cost and open-source equipment was established to facilitate the application of the APP. Conclusion: In the spirit of frugal science, our device may democratize glass pipette-puling and substantially promote the application of minimally invasive and precisely controlled delivery of therapeutics to the brain for finding more effective therapies of brain diseases.
