Generating golden Syrian hamsters with conditional alleles via zygote microinjection of CRISPR/Cas9

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We established the first conditional knockout (cKO) model in the golden Syrian hamster by CRISPR/Cas9‐mediated genome editing. Cas9 protein, two sgRNAs, and a donor plasmid carrying loxP‐flanked exon 2 of the ApoF gene were microinjected into one‐cell embryos. The floxed allele was efficiently generated (up to 27%) and transmitted through the germline.

Analytical Formulation of the Electric Field Induced by Electrode Arrays: Towards Automated Dielectrophoretic Cell Sorting

open access: yesMicromachines, 2017
Dielectrophoresis is defined as the motion of an electrically polarisable particle in a non-uniform electric field. Current dielectrophoretic devices enabling sorting of cells are mostly controlled in open-loop applying a predefined voltage on micro ...

Ionogel Actuators: A Review

open access: yesSmartBot, EarlyView.
Ionogels dynamically and functionally couple ionic liquids with polymer networks, enabling multiscale programmable deformation and motion under electrical, magnetic, optical, thermal, humidity, and chemical stimuli. This article systematically elucidates the constituent components, structural design, and multiscale actuation mechanisms of ionogel ...

Robotic Cell Micromanipulation Skill Learning via Imitation‐Enhanced Reinforcement Learning

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Humans can learn complex and dexterous manipulation tasks by observing videos, imitating and exploring. Multiple end‐effectors manipulation of free micron‐sized deformable cells is one of the challenging tasks in robotic micromanipulation. We propose an imitation‐enhanced reinforcement learning method inspired by the human learning process ...

Immune involvement in neuropsychiatric disorders: Insights from single‐cell transcriptomic studies

open access: yesPsychiatry and Clinical Neurosciences, EarlyView.
Neuropsychiatric disorders pose profound challenges to both research and treatment, largely due to their clinical heterogeneity and the limited understanding of their underlying biological mechanisms. While bulk RNA sequencing (bulk RNA‐seq) has been widely used to study gene expression, it cannot resolve cell‐type‐specific signals or detect rare ...

Advanced trajectory engineering of diffraction-resisting laser beams [PDF]

open access: yes, 2013
We introduce an analytical technique for engineering the trajectory of diffraction-resisting laser beams. The generated beams have a Bessel-like transverse field distribution and can be navigated along rather arbitrary curved paths in free space, thus ...

Studies on the non-specific esterases of Saccharomyces cerevisiae : a thesis in partial fulfillment [sic.] of the requirements for the degree of Master of Science in Microbiology at Massey University [PDF]

open access: yes, 1984
Twenty wine-making and three laboratory strains of Saccharomyces cerevisiae were examined for non-specific esterases by Polyacrylamide Gel Electrophoresis.
