Giant macular hole in Alport syndrome

Source: Morita, M., et al. Bacterial Cell Culture at the Single-cell Level Inside Giant Vesicles. J. Vis. Exp. (2019).This video demonstrates a method for culturing and observing individual bacterial cells encapsulated inside giant vesicles anchored to a supported lipid bilayer. The system enables stable, long-term imaging of single-cell growth dynamics in a confined, physiologically relevant...

This beginners' guide presents a general protocol for the preparation of Giant Unilamellar Vesicles (GUVs) via the droplet transfer method, discussing the critical steps and providing insights to help possible adjustments required for different applications, including synthetic biology and...

We present a protocol to determine the levels of overall macular pigment, lutein, and zeaxanthin optical density in the central and parafoveal regions of the retina. The protocol includes a novel adjustable track system used to measure macular pigment optical density in the foveal...

We demonstrate single-cell culture of bacteria inside giant vesicles (GVs). GVs containing bacterial cells were prepared by the droplet transfer method and were immobilized on a supported membrane on a glass substrate for direct observation of bacterial growth. This approach may also be adaptable to other...

Reconstituting functional membrane proteins into giant liposomes of defined composition is a powerful approach when combined with patch-clamp electrophysiology. However, conventional giant liposome production may be incompatible with protein stability. We describe protocols for producing giant liposomes from pure lipids or small liposomes containing ion...

Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...
