Transmission electron microscopy (TEM) is the method of choice to image the ultrastructure of cells or tissues. TEM allows the visualization of molecular complexes up to an atomic resolution. Thus, TEM data have led to important conclusions about cellular processes and supported findings obtained by functional analyses. In this chapter, we describe the preparation of Drosophila tissues for TEM and provide reliable step-by-step protocols for applying classical chemical fixation or high-pressure freezing-freeze substitution (HPF-FS) to preserve cellular structures.

Recently, 3-D porous architecture of the composites play a key role in cell proliferation, bone regeneration, and anticancer activities. The osteoinductive and osteoconductive properties of β-TCP allow for the complete repair of numerous bone defects. Herein, β-TCP was synthesized by wet chemical precipitation route, and their 3-D porous composites with HBO and Cu nanoparticles were prepared by the solid-state reaction method with improved mechanical and biological performances.

GV-58 is known to increase the opening time of the mammalian P-type calcium channel in presynaptic motor nerve terminals. GV-58 is suggested as a therapeutic agent for dampening the symptoms of amyotrophic lateral sclerosis. To further understand the mechanisms of GV-58 actions, the and crayfish neuromuscular junctions were used as models.

White tea has been scientifically proven to exhibit positive biological effects in combating chronic diseases, including cancer, metabolic syndrome, etc. Nevertheless, the anti-aging activity and mechanism of white tea on organisms exposed to a high-fat diet remain unexplored. Herein, we prepared a white tea aqueous extract (WTAE) from white peony in Fuding and assessed its in vivo antioxidant and anti-aging effects by employing a senescence model induced by lard, delving into the underlying molecular mechanisms through which the WTAE contributes to lifespan improvement.

The heart of larval serves as a model preparation in addressing cardiac function, as known genetic mutations can be mimicked to examine therapies. Pharmacological agents and function of proteins, like TRPA1, which affect ionic transport and ion concentrations can be investigated for their action on cardiac function in this model. To maintain function, the larval heart tube needs to remain viable; thus, a physiological saline is required.
