The Nucleosome Core Particle

Nucleosomes are the DNA-histone complex, where the DNA strand is wound around the histone core. The histone core is an octamer containing two copies of H2A, H2B, H3, and H4 histone proteins. The paradox Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...

A hyperglycemic clamp is used for measuring insulin release with a maintained higher blood glucose concentration. A hypoglycemic clamp is for measuring glucose production induced by counter-regulatory responses. Both methods use the same surgical procedure. Here, we present a clamp technique to assess systemic glucose metabolism.

Patch Clamp Electrophysiology

Neuron cell membranes are populated with ion channels that control the movement of charge into and out of the cell, thereby regulating neuron firing. One extremely useful technique for investigating the biophysical properties of these channels is called patch clamp recording. In this method, neuroscientists place a polished glass micropipette against a cell and apply suction to form a high resistance seal. This process isolates a small “patch” of membrane that contains one or more ion channels.

We present a protocol to use 3D-printed mounts to fix increment cores in the field without the necessity of unpacking and gluing them on wooden mounts. The new GSC holder allows placing the cores in a core microtome to cut their surface and directly transfer them to digital image capturing.
FAQs
The cladding stream shapes the interface around the central core while the two fluids move in parallel under predominantly laminar conditions. Because this arrangement avoids turbulent mixing, the surrounding phase can focus, sheath, or encapsulate the core. That control helps organize materials into structures with defined dimensions and composition.
Predominantly laminar movement keeps the core and cladding phases arranged as parallel streams rather than promoting turbulent intermixing. Maintaining this organized interface is important when researchers need the surrounding fluid to remain spatially associated with the core. The result is greater control over material organization and the structure formed downstream.
The key feature is the spatial relationship between the central core and the surrounding cladding phase. Their organized parallel movement allows the cladding to perform different roles, including narrowing or focusing the core, surrounding it as a sheath, or enclosing it through encapsulation. These roles determine how the resulting material is organized.
The workflow begins by introducing the core and cladding fluids separately into a microfluidic device. The central stream then travels within the surrounding stream, with both phases moving in parallel under predominantly laminar conditions. This configuration establishes a controlled interface that can be used to generate organized droplets, fibers, particles, or cell-containing structures.
In bioengineering, the configuration supports biomaterial fabrication, cell encapsulation, tissue engineering, and microscale delivery systems. Its value comes from controlling how materials or cells are positioned within a surrounding phase. That organization can help produce structured outputs with controlled dimensions and composition for different research and development goals.
Researchers can use the controlled core-cladding arrangement to form uniform droplets, fibers, particles, and cell-containing structures. The method also provides control over the dimensions and composition of these outputs. Such outcomes are relevant when bioengineering experiments require reproducible material organization, encapsulated cells, or microscale structures for delivery and tissue-related work.
