Entrapment of hemocyanin conformers as a tool for the definition of the structural model of cooperativity [PDF]
, 2013 Allostery has been established as a fundamental mechanism of regulation in most biological processes (Changeux, 2012). The most studied allosteric protein is hemoglobin, that has long been considered a paradigm for the investigation of allostery and ...

MORPHOLOGICAL VARIATION IN THE HORSESHOE CRAB LIMULUS POLYPHEMUS [PDF]
Evolution, 1981 Limulus polyphemus (L.) is one of the four species of horseshoe crabs alive today. These animals are well-known for their marked resemblance to fossils from the Mesozoic, and L. polyphemus has frequently been cited as an organism which has evolved very slowly over the last 200 million years (Mayr, 1963, p. 304; Selander et al., 1970; Williams, 1975, p.

Water Environment Research, Volume 97, Issue 2, February 2025.The paper reports on the ability of a Crustacean fish ectoparasitic to accumulate metals. The concentration of various metals in the parasite is compared to the concentration in the water and sediment in six localities along an anthropogenically impacted river.

Low Oxygen Levels Slow Embryonic Development of Limulus polyphemus
, 2016 The American horseshoe crab Limulus polyphemus typically spawns in the upper intertidal zone, where the developing embryos are exposed to large variations in abiotic factors such as temperature, humidity, salinity, and oxygen, which affect the rate of ...

Les constituants osmotiquement actifs des muscles et leur contribution à la régulation isosmotique intracellulaire chez Limulus polyphemus [PDF]
, 1966 peer reviewed1. The chemical composition of the blood and of the intracellular medium of the muscles has been studied in the king crab (Limulus polyphemus) and compared with that of marine decapods (Crustaceans) and of a scorpion, Androctonus australis ...

Non‐gonadal expression of piRNAs is widespread across Arthropoda
FEBS Letters, Volume 599, Issue 1, Page 3-18, January 2025.PIWI‐interacting RNAs (piRNAs) are known to protect the germline genome from transposable elements. Recently, evidence for their non‐gonadal expression has begun to emerge in some species. In this Perspective article, we combine an extensive literature review with a large analysis of transcriptomic data across arthropod species to investigate non ...

A Study on the Application of Recombinant Factor C (rFC) Assay Using Biopharmaceuticals
MicroorganismsGram-negative bacterial endotoxins can cause pathophysiological effects such as high fever when introduced into the bloodstream. Therefore, endotoxin testing is necessary when producing injectable pharmaceuticals.
