Aim: Determine if low-cost magnification devices (USB computer microscope, smartphone) enable the acquisition and maintenance of basic microsurgical skills by comparing skills learned using these devices against those learned using a surgical microscope. Determine whether skills acquired using these devices can be transferred to the surgical microscope.
Material And Methods: Twelve neurosurgical participants, ranging from faculty to postgraduate year-1 trainees, were randomly divided into three groups for training using a surgical microscope, smartphone, or USB microscope.

Despite advancements in engineered heart tissue (EHT), challenges persist in achieving accurate dimensional accuracy of scaffolds and maturing human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), a primary source of functional cardiac cells. Drawing inspiration from cardiac muscle fiber arrangement, a three-dimensional (3D)-printed multi-layered microporous polycaprolactone (PCL) scaffold is created with interlayer angles set at 45° to replicate the precise structure of native cardiac tissue. Compared with the control group and 90° PCL scaffolds, the 45° PCL scaffolds exhibited superior biocompatibility for cell culture and improved hiPSC-CM maturation in calcium handling.
