Toxicity assessment of zero valent iron nanoparticles on Artemia salina

Environmental Toxicology, 2017
The present study deals with the toxicity assessment of two differently synthesized zero valent iron nanoparticles (nZVI, chemical and biological) as well as Fe2+ ions on Artemia salina at three different initial concentrations of 1, 10, and 100 mg/L of ...

GMP reductase in Artemia salina

Biochimica et Biophysica Acta (BBA) - Enzymology, 1974
Abstract 1. 1. A GMP reductase (NADPH:GMP oxidoreductase (deaminating), EC 1.6.6.8) activity has been characterized, and partially purified, in Artemia salina extracts. The enzyme is specific for NADPH, has a k m of 0.01 mM for GMP, is maximally active at a pH value of approx. 8.5, requires thiol groups and is resistant to heating at

The hemoglobins of Artemia salina—III. Characterization

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1976
1. 1. Three brine shrimp hemoglobins (Hb-1, Hb-2, and Hb-3) have the same sedimentation coefficient (S20,w = 11.3S). The three native molecules have a molecular weight of about 230,000 and are stable at ionic strength 0.04–2.04 and pH 7.5–9.8. 2. 2.

Physical properties of Artemia salina ribosomes

Biochemistry, 1978
Eukaryotic ribosomes were isolated from the cryptobiotic embryos and from the further-developed free-swimming nauplii of the brine shrimp Artemia salina. Analytical boundary sedimentation and photon correlation spectroscopy yielded, respectively, the standard sedimentation and diffusion coefficients at infinite dilution, s degrees 20,w = 81 +/- 1 S and

Accumulation of cadmium by Artemia salina

Marine Biology, 1979
The relative importance of accumulation of cadmium by Artemia salina (L.) directly from solution and from ingested food has been studied at 3 cadmium concentrations (0.1, 1 and 10 ppm) under controlled experimental conditions. At each cadmium concentration, A.

Functional properties of the hemoglobins of Artemia salina L.

Comparative Biochemistry and Physiology Part A: Physiology, 1978
Abstract 1. 1. In hypoxic conditions Artemia salina L. forms 3 hemoglobins, which until now had only been characterized by their electrophoretic mobility. 2. 2. We have analysed the oxygen-binding properties of these 3 hemoglobins. 3. 3.

The genetics of Artemia salina: VII. Reproductive isolation

Journal of Heredity, 1976
Fifteen of 20 gonochoristic Artemia populations are crossfertile with diploid San Francisco shrimps, producing fertile F1 and viable F2 progeny. Partial sex linkage of white eye was observed and frequency of crossing over between the white and sex loci did not exceed the range of values observed in San Francisco shrimps.

On the Mode of Activation of Sequestered Messengers in Artemia salina

Differentiation, 1976
Activation of the dormant embryos of Artemia salina was marked by a rapid increase in 32P uptake which reached a stationary phase after 6 h of activation. The increase in 32P uptake by whole cysts was paralleled by its incorporation into nucleotides. Fractionation of acid-soluble nucleotides and alkaline hydrolysate of nucleic acids on Dowex-1-formate ...
