Conservation of the 5'-Terminal Nucleotide Sequences of Ribosomal 18-S RNA in Eukaryotes. Differential Evolution of Large and Small Ribosomal RNA [PDF]

open access: yesEuropean Journal of Biochemistry, 1976
The 5'-terminal nucleotide sequences of ribosomal 18-S and 28-S RNA of seven species of eukaryotes including three mammals, one bird, one amphibian, one echinoderm and one slime mold, were analyzed either by means of terminal phosphorylation of RNA with polynucleotide kinase of by fingerprint analysis of uniformly labeled RNA. The following conclusions

Crowding Promotes the Switch from Hairpin to Pseudoknot Conformation in Human Telomerase RNA [PDF]

open access: yesJ. Am. Chem. Soc., 2011, 133 (31), pp 11858--11861, 2011
Formation of a pseudoknot in the conserved RNA core domain in the ribonucleoprotein human telomerase is required for function. In vitro experiments show that the pseudoknot (PK) is in equilibrium with an extended hairpin (HP) structure. We use molecular simulations of a coarse-grained model, which reproduces most of the salient features of the ...

Long non‐coding RNAs as therapeutic targets in head and neck squamous cell carcinoma and clinical application

open access: yesFEBS Open Bio, EarlyView.
Long non‐coding RNAs (lncRNAs) occupy an abundant fraction of the eukaryotic transcriptome and an emerging area in cancer research. Regulation by lncRNAs is based on their subcellular localization in HNSCC. This cartoon shows the various functions of lncRNAs in HNSCC discussed in this review.

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.

Multifunctional Hydroxyapatite Coated with Gallium Liquid Metal‐Based Silver Nanoparticles for Infection Prevention and Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

Opportunities in Therapeutic mRNA Stabilization: Sequence, Structure, Adjuvants and Vectors

open access: yesAdvanced Therapeutics, EarlyView.
Current mRNA lipid nanoparticles rely on cold storage, which increases the cost and reduces access to the vaccines. As mRNA expands to other clinical opportunities, better methods to stabilize the medicines during shipping, storage, and delivery are needed.

Cytauxzoon felis and 'Candidatus Mycoplasma haemominutum' coinfection in a Brazilian domestic cat (Felis catus)

open access: yesRevista Brasileira de Parasitologia Veterinária
This article describes the first detection of Cytauxzoon felis, using molecular techniques, in a naturally infected domestic cat from Brazil, South America. Coinfection with 'CandidatusMycoplasma haemominutum' was also found. The molecular identification

Spatiotemporal Transcriptomic Profiling Reveals the Dynamic Immunological Landscape of Alveolar Echinococcosis

open access: yesAdvanced Science, EarlyView.
An unprecedented high‐resolution spatial atlas of the E. multilocularis infection foci is obtained, revealing the dynamic functions of neutrophils, Spp1+ macrophages, and fibroblasts during disease progression. The transition of parasite control strategy from “active killing” to “negative segregation” by the host may provide instructive insights into ...

Nucleotide sequence of a crustacean 18S ribosomal RNA gene and secondary structure of eukaryotic small subunit ribosoraal RNAs [PDF]

open access: yesNucleic Acids Research, 1984
The primary structure of the gene for 18 S rRNA of the crustacean Artemia salina was determined. The sequence has been aligned with 13 other small ribosomal subunit RNA sequences of eukaryotic, archaebacterial, eubacterial, chloroplastic and plant mitochondrial origin.

Morphological and molecular phylogenetic analysis of Bivesicula claviformis Yamaguti, 1934 infecting the tomato hind Cephalopholis sonnerati (Serranidae) in Saudi Arabia

open access: yesJournal of King Saud University: Science, 2022
Groupers are large predators in the Serranidae family that feed on fish and small invertebrates. Identification of parasitic taxa of groupers was done concerning their morphological and biological characteristics.
