Collecting neural cells from patients is an efficient way of monitoring health of an individual target, which, in turn, benefits the enhancement of medicines. The fabricated sample of neural cells is exposed to potential drugs for the analysis of neuron responses. 3D cell-printing as an emerging biofabrication technology has been widely used to mimic natural 3D models in in vitro tissue research, especially in vitro brain-like tissue constructs in neuroscience. Fabricated brain-like tissue constructs provide a 3D microenvironment for primary neural cells to grow within. After more than several weeks of in vitro culturing, the formation of neural circuits in structures equips them with the capability of sensitively responding to a stimulus. In this study, an in vitro layered brain-like tissue construct is first proposed and later developed by 3D cell-printing technology. The layered stru Publishing Ltd.This paper attempts to systematise all published experimental results for the Dose Reduction Factor (DRF) offered by leaded eyewear on clinicians performing interventional procedures. That way it presents a comprehensive analysis of the issue and a comparison of the various equipment models at different exposure geometries. Its main purpose is, however, to clarify the best choice for DRF within the possible diverse contexts and approaches to eye lens dose assessment. Evidence has been obtained that the lowest estimates of DRF are associated with the larger scatter incidence angles and that, except for a little better performance exhibited by wraparound eyeglasses, there is no real distinction between the DRFs for the different equipment categories. The dataset as a whole confirms that, when measurements for the concerned eyewear model and irradiation conditions are unattainable, assuming DRF=2
