Non-cavitated Lesions

Non-cavitated lesions are early-stage dental caries in which mineral is lost from enamel or dentin while the tooth surface remains intact. They develop when bacterial acids repeatedly lower the pH of dental biofilm, driving demineralization that may appear as a chalky white or brown opacity before structural collapse occurs. Because the surface is still preserved, these lesions can often be identified through visual examination and adjunctive detection methods and managed with preventive approaches that promote remineralization, such as fluoride exposure and improved plaque control. Studying non-cavitated lesions helps explain caries progression and supports minimally invasive dentistry.

Acoustic cavitation in liquids submitted to power ultrasound creates transient extreme conditions inside the collapsing bubbles, which are the origin of unusual chemical reactivity and light emission, known as sonoluminescence. In the presence of noble gases, nonequilibrium plasma is formed. The "hot" particles and the photons generated by collapsing bubbles are able to excite species in solution.

Here we present protocols for detergent-free homogenization of cultured mammalian cells based on nitrogen cavitation and subsequent separation of cytosolic and membrane-bound proteins by ultracentrifugation. This method is ideal for monitoring the partitioning of peripheral membrane proteins between soluble and membrane fractions.

A microfluidic chip was fabricated to produce pairs of gold dots for tandem bubble generation and fibronectin-coated islands for single-cell patterning nearby. The resultant flow field was characterized by particle image velocimetry and was employed to study various bioeffects, including cell membrane poration, membrane deformation, and intracellular calcium response.

We developed a method to successfully remove, process, section, and stain, for histopathological evaluation, mammary tissue that had originally been fixed on slides as whole mounts. This method may promote the collection and evaluation of mammary gland whole mounts in reproductive and developmental test guideline studies.
