Temperature regulates fatty acid desaturase and elongase at the transcriptional level and modulates the fatty acid profile in the early stage of the common carp (Cyprinus carpio)

open access: yesCzech Journal of Animal Science, 2023
This study explored the regulatory effect of temperature stress on fatty acid biosynthesis in the early stage of common carp (Cyprinus carpio) based on Δ6-fatty acids desaturase (Δ6FAD) and elongase-5 (ELOVL5) gene expression and fatty acid composition ...

Calibrated high-precision 17O-excess measurements using cavity ring-down spectroscopy with laser-current-tuned cavity resonance [PDF]

open access: yesAtmospheric Measurement Techniques, 2014
High-precision analysis of the 17O / 16O isotope ratio in water and water vapor is of interest in hydrological, paleoclimate, and atmospheric science applications. Of specific interest is the parameter 17O excess (Δ17O), a measure of the

Updating the occurrence of crassulacean acid metabolism (CAM) in the genus Clusia through carbon isotope analysis of species from Colombia

open access: yesPhotosynthetica, 2022
Clusia is a widely distributed neotropical genus with 321 currently described species. This remarkable genus is the only one known to contain trees sensu stricto with CAM photosynthesis. To survey the occurrence of CAM in Clusia species from Colombia, we

Effects of different dietary lipid sources on fatty acid composition and gene expression in common carp

open access: yesCzech Journal of Animal Science, 2020
The effects of fatty acid composition in artificial feed on the change in the fatty acid composition of carp muscles and the relationship between Δ6-Fad and Elovl5 genes participating in the regulation of fatty acid synthesis were studied. Juveniles were

Υγιή αδέρφια παιδιών με καρκίνο

open access: yesΨυχολογία: το Περιοδικό της Ελληνικής Ψυχολογικής Εταιρείας, 2020
Η κατανόηση του τρόπου με τον οποίο τα υγιή αδέρφια αντιλαμβάνονται και αναπαριστούν την υγεία και την αρρώστια ως καταστάσεις που επηρεάζουν ολόκληρη την οικογένεια αποτέλεσε τον βασικό άξονα αυτής της μελέτης.

De Sitter horizons & holographic liquids

open access: yesJournal of High Energy Physics, 2019
We explore asymptotically AdS2 solutions of a particular two-dimensional dilaton-gravity theory. In the deep interior, these solutions flow to the cosmological horizon of dS2.

Natural abundance of 15N of a spruce forest ecosystem under acid rain and manipulated clean rain field conditions

open access: yesJournal of Forest Science, 2008
We analysed stable isotopes of N in a spruce forest under ambient rainfall (no further manipulation of the atmospheric input) and clean rain application (10 years of reduced inorganic N- and acid-constituent input).

Quantum critical Eliashberg theory, the Sachdev-Ye-Kitaev superconductor and their holographic duals

open access: yesnpj Quantum Materials, 2022
Superconductivity is abundant near quantum critical points, where fluctuations suppress the formation of Fermi liquid quasiparticles and the BCS theory no longer applies.

Sum connectedness in proximity spaces

open access: yesApplied General Topology, 2021
The notion of sum δ-connected proximity spaces which contain the category of δ-connected and locally δ-connected spaces is defined. Several characterizations of it are substantiated. Weaker forms of sum δ-connectedness are also studied.

Methylglyoxal with glycine or succinate enhances differentiation and shoot morphogenesis in Nicotiana tabacum callus

open access: yesBiologia Plantarum, 2013
The aim of this study was to evaluate the influence of methylglyoxal (MG) on organogenesis and regeneration of tobacco (Nicotiana tabacum L.) plants from callus in media containing glycine or succinate.
