A New Technique for Harvesting Limbal Stem Cell Tissue for Transplantation Using an Automated Microkeratome and a Novel Globe-Fixation System.

Purpose: To introduce an unprecedented technique, instrumentation, and setup for the superficial limbus harvest from the human cadaver donor whole globe.

Methods: We studied several superficial limbus harvest alternatives, developed a preferred approach with our available instruments, and optimized it on a handful of (seropositive) cadaver donors of whole globes.

Results/technique: The globe was pressurized to about normal intraocular pressure by viscoelastic injection through the optic nerve stump.

Covid-19 shock: Development of strategic management framework for global energy.

Energy resources are vital for the economic development of any nation, and they are currently recognised as an essential commodity for human beings. Many countries are facing various levels up to severe energy crisis due to limited natural resources, coupled with the Covid-19 pandemic. This crisis can lead to the shutdown or restriction of many industrial units, limited energy access, exacerbating unemployment, simultaneous impacts on people's lives.
