Peyer's patches

Examples of Peyer's patches in the following topics:

• Histology of the Small Intestine

  • The jejunum and ileum do not have Brunner's glands in the submucosa, while the ileum has Peyer's patches in the mucosa, but the duodenum and jejunum do not.
  • Peyer's patches are organized lymph nodules.
  • Peyer's patches function as the immune surveillance system of the intestinal lumen and facilitate the generation of the immune response within the mucosa.

• Regulating Immune Tolerance

  • M cells are located in the Peyer's patch, which is a lymphoid nodule.
  • The dendritic cells migrate to an underlying tissue called a Peyer's patch.
  • Antigen-presenting cells, T cells, and B cells aggregate within the Peyer's patch, forming organized lymphoid follicles.

• Lymphoid Tissue

  • It is found mainly in the lymph nodes, but also in the lymphoid follicles in tonsils, Peyer's patches, spleen, adenoids, skin, and other areas associated with the mucosa-associated lymphoid tissue (MALT).

• Typhoid Fever

  • Third stage: a number of complications can occur: intestinal hemorrhage due to bleeding in congested Peyer's patches and intestinal perforation in the distal ileum.

• Maturation of B Cells

  • After reaching the IgM+ immature stage in the bone marrow, these immature B cells migrate to secondary lymphoid tissues (such as the spleen, lymph nodes, Peyer's patches, etc.) where they are called transitional B cells, and some of these cells differentiate into mature B lymphocytes.

• Patch Manager

  • Another frequent response to a patch is a freewheeling discussion, not necessarily about the patch itself, but about whether the concept behind the patch is good.
  • The patch manager's job is to make sure that patches don't "slip through the cracks."
  • The patch manager watches every mailing list thread that results from a patch posting.
  • When a patch gets no reaction at all, the patch manager waits a few days, then follows up asking if anyone is going to review it.
  • If she wants to ignore the patch completely, that's fine too; the patch manager will make sure it isn't forgotten.

• Transdermal Drug Administration

  • A transdermal patch is a medicated adhesive patch that is placed on the skin to deliver a specific dose of medication through the skin and into the bloodstream.
  • Vapor patch: In this type of patch, the adhesive layer not only serves to adhere the various layers together, but also to release vapor.
  • These patches administered scopolamine for motion sickness.
  • The highest-selling transdermal patch in the United States is the nicotine patch, which releases nicotine in controlled doses to help with cessation of tobacco smoking.
  • A 21mg dose Nicoderm CQ patch applied to the left arm.

• Documentation Manager

  • Documentation patches are usually much easier to review and apply than code patches.
  • Since the quantity is high, but the review burden fairly low, the ratio of administrative overhead to productive work is greater for documentation patches than for code patches.
  • Furthermore, most of the patches will probably need some sort of adjustment, in order to maintain a consistent authorial voice in the documentation.
  • In many cases, patches will overlap with or affect other patches, and need to be adjusted with respect to each other before being committed.
  • And the same patch manager (see the section called "Patch Manager") can track both code and documentation patches, filing them wherever the development and documentation teams want them, respectively.

• Vitiligo

  • The most notable symptom of vitiligo is depigmentation of patches of skin that occurs on the extremities.
  • Although patches are initially small, they often enlarge and change shape.
  • In mild cases, vitiligo patches can be hidden with makeup or other cosmetic camouflage solutions.

• Choosing Committers

  • A person might post only small patches, fixing fairly simple problems in the code; but if the patches apply cleanly, do not contain bugs, and are mostly in accord with the project's log message and coding conventions, and there are enough patches to show a clear pattern, then an existing committer will usually propose that person for commit access.
  • Many projects insist that the potential committer demonstrate a certain level of technical expertise and persistence, by submitting some number of nontrivial patches—that is, not only do these projects want to know that the person will do no harm, they want to know that she is likely to do good across the code base.
