Protocol for generating human cerebral organoids from two-dimensional cultures of pluripotent stem cells bypassing embryoid body aggregation.

Human cerebral organoids (hCOs) provide an excellent model for the study of human brain development and disease. Here, we present a protocol to obtain hCOs directly from two-dimensional (2D) pluripotent stem cell (PSC) cultures, avoiding cell dissociation and posterior embryoid body (EB) aggregation. We describe steps for subjecting 2D cultures to a neural fate and subsequently developing hCOs.

Theoretical Studies on Assembly, Physical Stability, and Dynamics of Viruses.

All matter must obey the general laws of physics and living matter is not an exception. Viruses have not only learnt how to cope with them but have managed to use them for their own survival. In this chapter, we will review some of the exciting physics that are behind viruses and discuss simple physical models that can shed some light on different aspects of the viral life cycle and viral properties.

Zirconium-Polycarboxylato Gel Systems as Substrates to Develop Advanced Fluorescence Sensing Devices.

This study presents the development of zirconium polycarboxylate gel systems as substrates for advanced fluorescence sensing devices. Zirconium-based metal-organic gels (MOGs) offer a promising alternative due to the robustness of the Zr-O bond, which provides enhanced chemical stability. In this work, zirconium polycarboxylate gels were synthesized using green solvents in a rapid room temperature method.

Host-specific viral predation network on coral reefs.

Viral infections are major modulators of marine microbial community assembly and biogeochemical cycling. In coral reefs, viral lysis controls bacterial overgrowth that is detrimental to coral health. However, methodological limitations have prevented the identification of viral hosts and quantification of their interaction frequencies.
