Towards understanding the phylogenetic history of Hydrozoa: Hypothesis testing with 18S gene sequence data

open access: yesScientia Marina, 2000
Although systematic treatments of Hydrozoa have been notoriously difficult, a great deal of useful information on morphologies and life histories has steadily accumulated. From the assimilation of this information, numerous hypotheses of the phylogenetic

Poly(A)-specific ribonuclease regulates the processing of small-subunit rRNAs in human cells [PDF]

open access: yes, 2016
Ribosome biogenesis occurs successively in the nucleolus, nucleoplasm, and cytoplasm. Maturation of the ribosomal small subunit is completed in the cytoplasm by incorporation of a particular class of ribosomal proteins and final cleavage of 18S-E pre ...

Interleukin-18 [PDF]

open access: yesJournal of Leukocyte Biology, 2003
Abstract Interleukin-18 (IL-18), a recently described member of the IL-1 cytokine superfamily, is now recognized as an important regulator of innate and acquired immune responses. IL-18 is expressed at sites of chronic inflammation, in autoimmune diseases, in a variety of cancers, and in the context of numerous infectious diseases.

The 18S rRNA genes of Haemoproteus (Haemosporida, Apicomplexa) parasites from European songbirds with remarks on improved parasite diagnostics

open access: yesMalaria Journal, 2023
Background The nuclear ribosomal RNA genes of Plasmodium parasites are assumed to evolve according to a birth-and-death model with new variants originating by duplication and others becoming deleted.

Reference Gene Selection for Expression Analyses by qRT-PCR in Dendroctonus valens

open access: yesInsects, 2020
Dendroctonus valens is the main pest of the genus Pinus. To facilitate gene expression analyses, suitable reference genes for adults and mature larvae of D. valens under different temperature conditions were determined.

Epiparasitic plants specialized on arbuscular mycorrhizal fungi [PDF]

open access: yes, 2002
Over 400 non-photosynthetic species from 10 families of vascular plants obtain their carbon from fungi and are thus defined as myco-heterotrophs. Many of these plants are epiparasitic on green plants from which they obtain carbon by 'cheating' shared ...

Denervated Schwann cells attract macrophages by secretion of leukemia inhibitory factor (LIF) and monocyte chemoattractant protein-1 in a process regulated by interleukin-6 and LIF [PDF]

open access: yes, 2002
Injury to peripheral nerves results in the infiltration of immune cells, which remove axonal- and myelin-derived material. Schwann cells could play a key role in this process by regulating macrophage infiltration.
