The cornea is unique in that it lacks vascular tissues. However, robust blood vessel growth and survival can be induced in the cornea by potent angiogenic factors. Therefore, the cornea can provide with us a valuable tool for angiogenic studies. This protocol demonstrates how to perform the mouse model of cornea pocket assay and how to assess the angiogenesis induced by angiogenic factors using this model.

This video demonstrates the hemocyte disturbance assay, evaluating hemocyte re-adhesion in Drosophila larvae's hematopoietic pockets. Mechanical disturbance releases resident hemocytes, elevating circulating hemocyte counts. Post-recovery, re-adherence of resident hemocytes is confirmed, illustrating reversibility.

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

FAQs
The sublingual mucosa is highly perfused, so active ingredients that dissolve against it can move into the bloodstream through mucosal absorption. This direct route supports systemic delivery without depending entirely on gastrointestinal uptake. In clinical administration, the result may be a more rapid or predictable effect when the medication is appropriate for sublingual use.
Positioning medication beneath the tongue limits the extent to which delivery depends on digestive conditions. It also reduces reliance on gastrointestinal uptake and exposure to first-pass hepatic metabolism, the initial processing of absorbed substances by the liver. These features can help preserve systemic availability for medications designed to be administered through the sublingual route.
Maintaining a tablet, film, or other suitable dosage form in the sublingual pocket allows it to dissolve directly against the mucosa. This sustained contact supports absorption at the intended site rather than allowing the dose to move immediately into the gastrointestinal tract. Consistent positioning can therefore contribute to more consistent systemic dosing.
The medication should be placed in the space beneath the tongue in the form prescribed for sublingual administration. It is then kept in that pocket so the tablet, film, or other dosage form can dissolve against the sublingual mucosa. This positioning maintains contact with the absorptive tissue and supports the intended systemic delivery pathway.
Clinicians may select sublingual administration when a suitable medication requires rapid or predictable systemic delivery. The approach is relevant when avoiding sole reliance on gastrointestinal uptake or reducing exposure to first-pass hepatic metabolism is important. Its use depends on whether the active ingredient and dosage form are appropriate for absorption through the sublingual mucosa.
When correctly matched to a suitable medication, this technique can support direct systemic absorption, consistent dosing, and a faster onset. The expected outcome depends on maintaining the dosage form against the sublingual mucosa while it dissolves. It is therefore useful for medication delivery situations in which timing and predictability of systemic exposure matter.
