The periodic shedding of part or all of a chitin-based cuticle, which is then replaced by a new cuticle. An example of this is found in Drosophila melanogaster.

OBSOLETE. The chemical reactions and pathways involving the fat body. A fat body is a fat-containing cellular structure which serves as an energy reserve. As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a microvillus on a follicle cell. A microvillus is a thin cylindrical membrane-covered projection on the surface of an animal cell containing a core bundle of actin filaments.

The morphological, biochemical and genetic changes that induce the differentiation of non-pathogenic parasites into pathogenic metacyclic parasites in the Trypanosomatidae species. The pathogenic parasites are known as metacyclic trypomastigotes in Trypanosoma and metacyclic promastigotes in Leishmania.

The process of hardening of a chitin-based cuticle.

Catalysis of the reaction: 4-hydroxytryptamine + ATP = 4-hydoxytryptamine 4-phosphate + ADP + H(+).

OBSOLETE. Synthesis and deposition of a protein-based noncellular, hardened, or membranous secretion from an epithelial sheet. An example of this is found in Caenorhabditis elegans.

Catalysis of the reaction: tryptamine + reduced acceptor + O(2) <=> 4-hydroxytryptamine + acceptor + H(2)O.

The regulated release of milk from the mammary glands and the period of time that a mother lactates to feed her young.

Binding to a pyrimidine ribonucleoside, a compound consisting of a pyrimidine base linked to ribose.

Binding to a ribonucleoside, a compound consisting of a purine or pyrimidine nitrogenous base linked to ribose.

Catalysis of the reaction: 2 S-adenosyl-L-methionine (SAM) + 4-hydroxytryptamine 4-phosphate (norbaeocystin) <=> 2 S-adenosyl-L-homocysteine + psilocybin.

The adhesion of the puparia of Diptera to their substrate; normally effected by a 'glue' secreted by the larval salivary gland and expectorated at the time of pupariation.

The attachment of a multicellular organism to a surface or material.

A protein activation cascade that contributes to blood coagulation and consists of the interactions among high molecular weight kininogen, prekallikrein, and factor XII that lead to the activation of clotting factor X.

A sequential series of modifications to a set of proteins where the product of one reaction catalyzes the following reaction, ultimately leading to the generation of a mature protein. Modifications typically include proteolysis or covalent modification, and may also include binding events.

The sequential process in which the multiple coagulation factors of the blood interact, ultimately resulting in the formation of an insoluble fibrin clot; it may be divided into three stages: stage 1, the formation of intrinsic and extrinsic prothrombin converting principle; stage 2, the formation of thrombin; stage 3, the formation of stable fibrin polymers.

The stopping of bleeding (loss of body fluid) or the arrest of the circulation to an organ or part.

Binding to a deoxyribonucleotide, any compound consisting of a deoxyribonucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the deoxyribose moiety.

A protein activation cascade that contributes to blood coagulation and consists of the self-limited process linking exposure and activation of tissue factor to the activation of clotting factor X.
